Field of technology to which the invention relates

The present invention relates to the field of communications and, in particular, to a method and apparatus for processing information, a storage medium, a processor and an electronic device.

BACKGROUND OF THE INVENTION

Currently, in the prior art, in the process of determining the Hybrid Automatic Repeat reQuest (HARQ) process ID in the New Radio (NR) Uu system, the base station can allocate a downlink transmission resource with semi-persistent scheduling (SPS) for the terminal. When configuring an SPS transmission resource on the downlink, the base station may configure multiple HARQ process IDs for each set of SPS transmission resources. In addition, in an NR system, the base station may also allocate a configured uplink grant (UL CG for short) to the terminal. When configuring a UL CG resource, the base station may configure multiple HARQ process IDs for each set of UL CG resources.

It can be seen that the prior art only provides a method for determining a HARQ process ID when a base station configures a downlink SPS transmission resource or a UL CG resource, but a method for determining a HARQ process ID for a configured grant (abbreviated as CG) of a direct connection (SL) is not used.

Detailed description

In order for one skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments represent only a portion, and not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without expending inventive effort are within the scope of legal protection of the present invention.

It should be noted that the terms “first”, “second” or the like in the description, claims and drawings of the present invention are used to distinguish like items and are not necessarily used to describe a particular order or order of priority. It should be understood that data used in this manner may be exchanged under appropriate circumstances, so that embodiments of the present invention described herein may be implemented in a manner different from those depicted or described herein. In addition, the terms “including,” “having,” and any variations thereof are intended to cover non-exclusive inclusion, such as processes, methods, systems, products, or devices comprising a sequence of steps or elements, not necessarily limited to those steps or elements expressly enumerated, but may include other steps or elements not expressly listed or inherent in the processes, methods, products or devices.

In fig. 1 is a schematic illustration of a D2D transmission technology according to the prior art. As shown in FIG. 1, Device to Device (D2D) communication is a Sidelink (SL) transmission technology, which is different from the way communication data is received or sent through a base station in a traditional cellular communication system. Since the D2D system adopts a direct terminal-to-terminal communication method, the D2D system has higher spectral efficiency and lower transmission delay. Based on D2D transmission technology, two transmission modes, i.e., Mode A and Mode B, are defined for the Internet of Vehicles system in the third generation partnership project (3GPP).

In Mode A, the terminal's transmission resource is allocated to the base station. The terminal transmits data over a direct connection according to the resource allocated by the base station. The base station may allocate the resource for a single transmission to the terminal, or may allocate the resource to semi-persistent transmission to the terminal. In mode B, the terminal selects one resource in the resource pool for data transmission.

Since it is necessary to support autonomous driving in a NR vehicle-to-everything (V2X) system, there are higher requirements for data communication between vehicles, such as higher throughput, lower latency, higher reliability, greater coverage range and more flexible resource allocation. NR-V2X provides unicast and multicast modes. In addition, V2X with Long Term Evolution (LTE) also supports broadcast mode.

For unicast mode, unicast transmission is performed between a terminal on the sending side and a terminal on the receiving side. In fig. 2 is a schematic diagram of a unicast transmission mode according to the prior art. As shown in FIG. 2, UE1 is a sending-side terminal and UE2 is a receiving-side terminal, so that unicast transmission can be performed between UE1 and UE2.

For multicast transmission mode, the receiving side terminal includes all terminals in a communication group or all terminals within a certain transmission distance. In fig. 3 is a schematic diagram of a multicast transmission mode according to the prior art. As shown in FIG. 3, UE1, UE2, UE3 and UE4 constitute a communication group, in which UE1 is a data sender, and all other terminal devices UE2, UE3 and UE4 in the group are receiving-side terminals.

For the broadcast mode, the receiving side terminal may be any terminal. In fig. 4 is a schematic diagram of a broadcast mode according to the prior art. As shown in FIG. 4, if UE1 is a sending-side terminal, all other terminals UE2, UE3 and UE4 around UE1 can be set as receiving-side terminals.

In addition, NR-V2X introduces different transmission modes, i.e., mode 1 and mode 2. In mode 1 (i.e., the above-mentioned mode A), the network allocates transmission resource to the terminal, and in mode 2 (i.e., the above-mentioned mode B), the terminal selects the transmission resource. In order to increase the reliability of data transmission, a direct connection feedback channel is introduced. In fig. 5 is a schematic representation of the data transmission process in NR-V2X according to the prior art. As shown in FIG. 5, UE1 and UE2 represent a unicast communication link. UE1 sends direct connection data to UE2. UE2 sends forward connection feedback information, i.e., HARQ acknowledgment (ACK) or negative acknowledgment (NACK), to UE1 according to the detection result of received forward connection data. After receiving feedback information from UE2, UE1 decides whether to retransmit the data to UE2. In addition, UE1 may also decide whether the receiving side terminal UE2 should send feedback information. For example, for broadcast communication, the receiving side does not need feedback, but for unicast communication, the receiving side needs feedback to improve the reliability of the system. Specifically, UE1 contains indication information in Sidelink Control Information (SCI) to indicate whether the receiving side terminal needs to perform sidelink feedback.

NR-V2X also supports Mode 1 and Mode 2 resource allocation modes. In Mode 2, the terminal selects a transmission resource autonomously in the resource pool for direct connection transmission, that is, the above-mentioned Mode B. In Mode 1, the network side device allocates the resource for the terminal transmission of the configured direct connection grant, that is, in the above-mentioned mode A. Specifically, the network side device may allocate the configured direct connection grant transmission resource to the terminal by Dynamic Scheduling, and may also allocate the SL CG transmission resource to the terminal. For CG resource allocation mode, there are mainly two configured grant modes: type-1 Configured Grant and type-2 Configured Grant.

Configured permission type 1 means that the network side device configures the transmission resource of the configured direct connection permission for the terminal through Radio Resource Control (RRC) signaling information. All transmission resources and transmission parameters, including time domain resource, frequency domain resource, demodulation reference signal (DMRS) and modulation coding scheme (MCS), etc., are configured by RRC signaling information. The terminal then performs direct connection transmission on the configured time-frequency resources using the configured transmission parameters.

The configured Type 2 grant applies a two-stage resource allocation mode, that is, RRC mode plus Downlink Control Information (DCI). First, transmission resources and transmission parameters, including a period of time-frequency resources, and a number of HARQ processes, etc. are configured by RRC signaling information, and then transmission of the configured type 2 grant is activated by DCI, and other transmission resources and transmission parameters are simultaneously configured, including time domain resource, frequency domain resource and MCS, etc. After receiving the RRC signaling information, the user equipment (UE) cannot immediately use the resource and parameter configured by this upper layer parameter for direct connection transmission. However, the UE additionally needs to accept the appropriate DCI to activate and configure other transmission resources and transmission parameters before it can perform direct connection transmission. In addition, the network side device can disable configuration transfer via DCI. When a terminal receives DCI for deactivation, it can no longer use the transmission resource for direct connection transmission.

If a network-side device has allocated a transmission resource of a configured grant to a terminal, when the terminal has direct connection data to be transmitted, the terminal can directly use the transmission resource for transmission without sending a Scheduling Request (SR) or a Buffer Status Report. Report, BSR) to a device on the network side to request transmission resource, thereby reducing transmission delay. In the configured direct connection permission, the network side device allocates periodic transmission resources, and in each period, the network side device can configure multiple transmission resources. In fig. 6 is a schematic diagram of the configuration of a transmission resource by a network-side device according to the prior art. As shown in FIG. 6, the network-side device configured grant transmission resources are periodic retransmission resources, with four direct connection configured grant transmission resources included in each period.

In the resource allocation mode of mode 1, if the direct connection feedback is in the active state, the receiving side terminal will send feedback information to the sending side terminal according to the condition of receiving the direct connection data. The sending side terminal reports the forward link feedback (SL HARQ-ACK) information to the network side device. The network side device then decides whether to allocate the retransmission resource according to the SL HARQ-ACK reported by the sending side terminal.

In transmitting the configured forward connection grant, a network-side device may configure a transmission resource of the configured forward connection grant for the terminal and allocate a transmission resource of a Physical Uplink Control Channel (PUCCH). The terminal may report forward connection feedback information to the network side device in the PUCCH. If the network side device receives the NACK feedback information reported by the terminal, the retransmission resource will be allocated through dynamic scheduling, and the HARQ process ID must be specified in the dynamically scheduled DCI to indicate the HARQ process that owns the retransmission resource allocated to the terminal. Therefore, the network side device needs to determine the HARQ process ID corresponding to the forward link transmission.

It should be noted that the actions depicted in the flowchart graphics may be performed, for example, on a computer system having a set of computer-executable instructions, and although the flowchart shows a logical order, the actions shown or described may be performed in the order different from those contained in this document in some cases.

In an embodiment, an information processing method performed on a terminal device is provided. In fig. 7 is a flowchart of an information processing method according to an embodiment of the present invention. As shown in FIG. 7, the method includes the following steps.

In action S70, configuration information is received from a network side device, wherein the configuration information is used to configure a forward connection configured permission transmission resource, and the forward connection configured permission transmission resource is a transmission resource located in a resource pool.

In action S71, time domain information corresponding to the transmission resource of the configured direct connection permission is determined based on the configuration information.

In action S72, the ID of the first hybrid automatic retransmission request process is determined according to the time domain information corresponding to the transmission resource of the configured forward connection permission.

Through the above steps, configuration information can be received from a network-side device, wherein the configuration information is used to configure a transmission resource of the configured direct connection permission, and the transmission resource of the configured direct connection permission is a transmission resource located in a resource pool, time domain information corresponding transmission resource of the configured direct connection grant is determined by the configuration information, and the ID of the first process of the hybrid automatic retransmission request is determined according to the time domain information corresponding to the transmission resource of the configured direct connection grant, thereby achieving the object of providing a method for determining the HARQ process ID of the configured direct connection grant connections. In this way, the following technical effects are achieved: the technical gap due to which the HARQ process ID cannot be determined in terms of configured direct connection permission is effectively filled; the flexibility and variety of the method for determining the HARQ process ID is increased, and the technical problem of the lack of a method for determining the HARQ process ID for a configured direct connection enablement in the prior art is resolved.

In the configuration information, not only the transmission resource of the configured direct connection grant may be configured, but the PUCCH transmission resource may also be configured. Herein, the PUCCH transmission resource is the PUCCH resource corresponding to the configured direct connection permission transmission resource, that is, the forward connection feedback information associated with the direct connection data transmitted in the configured direct connection permission transmission resource is notified to the network side device by the resource PUCCH transmissions. For the terminal device, the ID of the first process of the hybrid automatic retransmission request may be determined according to the position in the time domain of the transmission resource of the configured direct connection grant.

A resource pool can be one of several resource pools. In particular, in FIG. 8 is a schematic diagram of a resource pool definition according to an optional embodiment of the present invention. As shown in FIG. 8, the resource pool is determined in a System Frame Number (SFN) period or a Direct Frame Number (DFN) period as follows. Taking a subcarrier spacing of 15 kHz as an example, the DFN period includes 10240 subframes (or slots) corresponding to subframes 0, 1, 2, ... and 10239, respectively. Subframes that cannot be used for direct connection transmission, such as synchronization subframe, downlink subframe, special subframe (i.e., downlink subframe and special subframe in TDD system) and reserved subframe, are removed, and the number of remaining subframes is The number of these remaining subframes can be divided by without a trace. Bitmap repeats periodically in the remaining subframes, where a bit equal to 1 indicates that the subframe in the remaining subframes corresponding to the bit belongs to the resource pool, otherwise it does not belong to the resource pool.

The DFN period includes 10240 subframes, and the synchronization signal period is 160 ms. Assuming that two synchronization subframes are included in one synchronization period, therefore, there are 128 synchronization subframes in one DFN period, and the length of the bitmap for indicating resources of the resource pool temporary domain is 10 bits. Thus, two reserved subframes are required, and the number of remaining subframes is (10240-128-2=10110) and can be divided by the length of the bitmap, i.e. 10, without remainder, so the remaining subframes are renumbered as 0, 1, 2, ... and 10109. The first three bits of the bitmap are 1, and the remaining seven bits are 0. That is, in the remaining subframes, the first three subframes in every 10 subframes belong to the resource pool, and the remaining subframes do not belong to the resource pool. Since the bitmap needs to be repeated 1011 times in the remaining subframes to indicate that all subframes belong to the resource pool, and 3 subframes are included in each bitmap period, a total of 3033 subframes belong to the resource pool in one DFN period. Each interval index in the resource pool corresponds to one interval index in the DFN period. For example, intervals 0, 1, 2, 3, 4 and 5 in the resource pool correspond to intervals 0, 2, 4, 13, 14 and 15 in the DFN period, respectively. The network-configured forward connection configured permission transmission resource will be associated with one resource pool, and the network-configured forward connection configured permission transmission resource is a transmission resource located in one resource pool.

In an embodiment, the time domain information corresponding to the configured direct connection grant transmission resource is an interval index of the configured direct connection permission transmission resource in the resource pool. For example, for the above embodiment, the resource pool in which the configured direct connection permission transmission resource is located includes 3033 subframes, so the time domain information corresponding to the configured direct connection permission transmission resource is an interval index in the resource pool, that is, an interval index in the range [ 0.3032].

Optionally, the time domain information corresponding to the transmission resource of the configured direct connection grant is a slot index in slots that may be used for the resource pool. For example, for the above embodiment, the set of slots that are optionally used for the resource pool are the remaining subframes for which the corresponding slot index range is [0, 10109].

Optionally, at least one of the following parameters may be determined by the above configuration information: (1) the transmission resource period of the configured direct connection enable; (2) the total number of HARQ process IDs corresponding to the currently configured resolution; (3) a HARQ process ID offset used to determine the ID of the first HARQ process corresponding to the currently configured resolution; (4) an interval corresponding to the time domain resource of the transmission resource of the configured direct connection permission.

In one implementation, the configuration information includes interval offset information and a period parameter, and the transmission resource of the configured direct connection permission is determined according to the interval offset information and the period parameter; wherein the interval offset indicating information is used to determine the time domain information of the first transmission resource of the configured forward connection grant in the system frame number period (or in the forward frame number period). The slot offset information is represented by a number of physical slots, wherein the number of slots represents a number of physical slots or a number of logical slots, wherein the logical slots represent slots in a resource pool associated with a transmission resource of a configured direct connection grant, or slots that may , are used for resource pooling.

The number of slots represents the number of physical slots or the number of logical slots, where the logical slots are slots in the resource pool associated with the transmission resource of the configured direct connection grant, or slots that may be used for the resource pool.

Optionally, in action S72, the ID of the first hybrid automatic retransmission request process is determined according to the time domain information corresponding to the transmission resource of the configured direct connection permission, which may include the following execution actions S720 and S722.

In action S720, the period parameter is determined based on the configuration information, where the period parameter is the transmission resource period of the configured direct connection permission.

In action S722, the ID of the first hybrid automatic retransmission request process is determined according to the time domain information corresponding to the transmission resource of the configured forward connection permission and the period parameter.

Optionally, the configured direct connection grant transmission resource period is represented by a number of slots, which is used to describe the number of slots in the resource pool where the configured direct connection permission transmission resource is located. Optionally, the transmission resource period of the configured direct connection grant is represented by a number of slots to describe the number of potential slots for the resource pool.

Optionally, the transmission resource period of the configured direct connection grant is represented by a number of logical slots or a number of physical slots.

If the periodicity parameter is represented by the number of slots, the corresponding first HARQ process ID is determined by the following formula according to the position in the time domain of the transmission resource of the configured direct connection grant in the resource pool where the configured direct connection grant is located.

HARQ process ID = [floor (CURRENT_slot/periodicity)] mod nrofHARQ-Processes + harq-procID-offset.

In the above formula, mod represents the modulo operation and floor represents the round down operation.

Still, as shown in FIG. 8, the network side device configures the transmission resource of the configured direct connection permission in the resource pool. The three intervals of the configured direct connection permission period represent three intervals in the resource pool. The first position of the configured direct connection permission interval is interval 2. According to the configured direct connection permission period, intervals such as interval 5, interval 8 and interval 11, etc. will include the configured direct connection permission transmission resource.

In the above formula for calculating the HARQ process ID, CURRENT_slot represents the slot where the transmission resource of the configured direct connection permission is located in the resource pool, namely slot 2, slot 5, slot 8, slot 11, slot 14, slot 17, ... and slot 3032, etc. The periodicity parameter represents the transmission resource period of the configured direct connection grant, which can be represented by the number of slots in the resource pool where the configured grant is located, that is, the period is 3 slots. If nrofHARQ-Processes=4 and harq-procID-offset=0 are configured, then the HARQ process IDs corresponding to the configured forward connection enable are 0, 1, 2 and 3, respectively. In this embodiment, the HARQ process IDs corresponding to the configured forward connection grant transmission resources at positions in the time domain such as slot 2, slot 5, slot 8, slot 11, slot 14 and slot 17, etc. are respectively 0, 1, 2, 3, 0 and 1, etc.

In the process of determining the ID of the first process of the hybrid automatic retransmission request according to the time domain information corresponding to the configured direct connection permission transmission resource, the network side device configures the configured direct connection permission transmission resource for the terminal. According to the position in the time domain of the transmission resource of the configured direct connection grant on the direct connection, the corresponding ID of the first HARQ process can also be determined by the following formula.

HARQ process ID = [floor (CURRENT_slot × 10/(numberOfSlotsPerFrame × periodicity))] mod nrofHARQ-Processes + harq-procID-offset.

Herein, in the above formula, the meanings of various parameters are as follows.

(1) numberOfSlotsPerFrame represents the number of slots contained in each radio frame (frame or radio frame).

(2) periodicity represents the transmission resource period of the configured direct connection grant and is represented in milliseconds (ms).

(3) nrofHARQ-Processes represents the total number of HARQ process IDs corresponding to the currently configured direct connection enable.

(4) harq-procID-offset is used to determine the ID of the first HARQ process corresponding to the currently configured forward connection enable; in an optional embodiment, the value of this parameter is 0 if the network side device does not configure this parameter.

CURRENT_slot represents the slot corresponding to the resource of the temporary domain of the transmission resource of the configured direct connection permission, the value range of this parameter is [0, N-1], N represents the total number of slots contained in the current resource pool, and the slot index is the index of the slot in the resource pool, where the configured direct connection permission is located.

In an optional embodiment, CURRENT_slot = [(DFN × numberOfSlotsPerFrame) + frame slot number]; where the slot number in the frame represents the transmission resource index of the configured direct connection grant in the radio frame, and its value range is [0, M-1], and M represents the total number of slots included in the radio frame; DFN represents the forward frame number; numberOfSlotsPerFrame represents the number of slots contained in each radio frame (frame or radio frame), which is determined by the subcarrier spacing of the forward connection carrier in which the forward connection transmission is located, or determined by the subcarrier spacing of the uplink.

In the above formula, mod represents the modulo operation and floor represents the round down operation.

Optionally, the above method may further include the following actuation S73.

In action S73, the first direct connection data is transmitted in a configured direct connection permission resource, wherein the first direct connection data corresponds to the ID of the first process of the hybrid automatic retransmission request.

The HARQ process ID corresponding to the configured direct connection grant transmission resource determined by the terminal device through the above method is the first HARQ process ID. The terminal device may use the first HARQ process ID to transmit the first direct connection data. The first forward connection data may include a forward connection physical control channel (PSCCH) and a forward connection physical shared channel (PSSCH). Additionally, the terminal device may also include the first HARQ process ID in the Sidelink Control Information (SCI), that is, the sidelink data transmitted on the PSSCH corresponds to the first HARQ process ID.

Optionally, the above method may further include the following operating actions S74 and S75.

In action S74, downlink control information is received from a network side device, wherein the downlink control information is used to schedule a forward connection transmission resource, and the downlink control information contains the ID of a first hybrid automatic retransmission request process.

In action S75, the first forward connection data is retransmitted in the forward connection transmission resource scheduled by the downlink control information.

In transmitting the configured direct connection grant, the network side device may configure a PUCCH transmission resource for the terminal device. The terminal may report forward connection feedback information to the network side device in the PUCCH transmission resource.

Optionally, the network side device configures one PUCCH transmission resource in each configured forward connection enable period. In one configured forward connection enable period, the terminal sends first forward connection data to the receiving side terminal via a configured forward connection enable transmission resource that corresponds to the ID of the first HARQ process. If the terminal receives forward connection feedback information NACK sent by the receiving terminal, it will report the NACK to the network via PUCCH in the period. If the network side device receives the NACK feedback information reported by the terminal, it dynamically allocates the retransmission resource for direct connection transmission by DCI and indicates the ID of the first HARQ process in DCI, so that the terminal device retransmits the first direct connection data in the direct connection transmission resource. direct connection scheduled by downlink control information.

Optionally, the above method may further include the following actuation S76.

In action S76, the second direct connection data is transmitted in a transmission resource of the configured direct connection permission based on the mapping relationship between the hybrid automatic retransmission request first process ID and the hybrid automatic retransmission request second process ID, wherein the second direct connection data corresponds to the second process ID hybrid automatic retransmission request.

When the terminal transmits direct connection data using the configured direct connection permission transmission resource, the ID of the first HARQ process is determined according to the time domain information of the configured direct connection permission transmission resource. Additionally, the terminal may determine in advance a mapping relationship between the first HARQ process ID and the second HARQ process ID. The terminal device may transmit second direct connection data in a transmission resource of the configured direct connection permission using the second HARQ process ID based on the mapping relationship. The second forward connection data may include PSCCH and PSSCH. Additionally, the terminal device may also include a second HARQ process ID in the SCI, that is, the direct connection data transmitted on the PSSCH corresponds to the second HARQ process ID.

Optionally, the above method may further include the following operating actions S77 and S78.

In action S77, downlink control information is received from a network side device, wherein the downlink control information is used for forward link transmission resource scheduling, and the downlink control information contains the ID of the first hybrid automatic retransmission request process.

In action S78, the second forward connection data is retransmitted in the forward connection transmission resource scheduled by the downlink control information.

The network side device determines that the process ID corresponding to the transmission resource of the configured direct connection grant is the ID of the first HARQ process, through the PUCCH transmission resource. When a network-side device receives a NACK, the retransmission resource is dynamically allocated for direct connection transmission via the DCI, and the ID of the first HARQ process is specified in the DCI. After receiving the DCI and obtaining the first HARQ process ID from the DCI, the terminal device may determine that the retransmission resource is a retransmission scheduling for direct connection transmission of the second HARQ process ID according to the mapping relationship between the first HARQ process ID and the second HARQ process ID.

It can be seen that the ID of the first HARQ process determined by the terminal device according to the time domain information of the configured direct connection permission transmission resource may be different from the ID of the second HARQ process used when data is transmitted using the configured direct connection permission transmission resource, and the terminal device may also determine a mapping relationship between the first HARQ process ID and the second HARQ process ID, so that the terminal device has greater flexibility or autonomy to determine the HARQ process ID for transmission over the direct connection.

The embodiment also provides another information processing method running on the network side device. In fig. 9 is a flow diagram of another information processing method according to one embodiment of the present invention. As shown in FIG. 9, the method includes the following steps S90 to S92.

In step S90, first configuration information is determined, wherein the first configuration information is used to configure a transmission resource of the configured direct connection permission, and the transmission resource of the configured direct connection permission is a transmission resource located in the resource pool.

In action S91, time domain information corresponding to the transmission resource of the configured direct connection permission is determined based on the first configuration information.

In action S92, the ID of the first process of the hybrid automatic retransmission request is determined according to the time domain information corresponding to the transmission resource of the configured direct connection grant.

Through the above steps, first configuration information is determined and sent to the terminal, wherein the first configuration information is used to configure a transmission resource of the configured direct connection permission, and the transmission resource of the configured direct connection permission is a transmission resource located in the resource pool, time domain information corresponding to the transmission resource configured direct connection permission is determined by the first configuration information, and the first process ID of the hybrid automatic retransmission request is determined according to the time domain information corresponding to the transmission resource of the configured direct connection permission, thereby achieving the object of providing a method for determining a HARQ process ID for the configured direct connection permission . In this way, the following technical effects are achieved: the technical gap due to which the HARQ process ID cannot be determined in terms of configured direct connection permission is effectively filled; and the flexibility and variety of the method for determining the HARQ process ID is increased, and the technical problem of the lack of a method for determining the HARQ process ID for a configured direct connection enablement in the prior art is solved.

In the first configuration information, not only a transmission resource of the configured forward connection permission may be configured, but also a PUCCH transmission resource may be configured. The configured direct connection permission transmission resources configured by the network side device for the terminal device are periodic, with no more than N_max (N_max = 2 or 3) configured direct connection permission transmission resources included in each period, and one PUCCH transmission resource configured in each period. The terminal device transmits direct connection data using a transmission resource of the configured direct connection permission in a period, and reports direct connection feedback information to the network side device using a PUCCH transmission resource. Then, the network side device determines whether to allocate the retransmission resource to the terminal according to the forward connection feedback information.

For the network side device, firstly, the PUCCH transmission resource can be determined according to the configuration information; second, the PUCCH is received in the transmission resource of the PUCCH, and according to the PUCCH, the SL CG period (i.e., the configured forward connection grant period to which the PUCCH belongs) corresponding to the PUCCH and the transmission resource of the configured forward connection grant in the period are determined, and then determined ID of the first HARQ process according to the time domain information of the transmission resource of the configured direct connection grant.

A resource pool can be one of several resource pools. In particular, still, as shown in FIG. 8, a resource pool is determined within one SFN or DFN period as follows. Taking a subcarrier spacing of 15 kHz as an example, the DFN period includes 10240 subframes (or slots) corresponding to subframes 0, 1, 2, ... and 10239, respectively. Subframes that cannot be used for direct connection transmission, such as synchronization subframe, downlink subframe, special subframe (i.e., downlink subframe and special subframe in TDD system) and reserved subframe, are removed, and the number of remaining subframes is The number of these remaining subframes can be divided by without a trace. Bitmap repeats periodically in the remaining subframes, with a bit equal to 1 indicating that the subframe in the remaining subframes corresponding to the bit belongs to the resource pool, otherwise it does not belong to the resource pool.

The DFN period includes 10240 subframes, and the synchronization signal period is 160 ms. Assuming that two synchronization subframes are included in one synchronization period, therefore, there are 128 synchronization subframes in one DFN period, and the length of the bitmap to indicate the resource pool temporary domain resources is 10 bits. Thus, two reserved subframes are required, and the number of remaining subframes is (10240-128-2=10110) and can be divided by the length of the bitmap, i.e. 10, without remainder, so the remaining subframes are renumbered as 0, 1, 2, ... and 10109. The first three bits of the bitmap are 1, and the remaining seven bits are 0. That is, in the remaining subframes, the first three subframes in every 10 subframes belong to the resource pool, and the remaining subframes do not belong to the resource pool. Since the bitmap needs to be repeated 1011 times in the remaining subframes to indicate that all subframes belong to the resource pool, and 3 subframes are included in each bitmap period, a total of 3033 subframes belong to the resource pool in one DFN period. Each interval index in the resource pool corresponds to one interval index in the DFN period. For example, intervals 0, 1, 2, 3, 4 and 5 in the resource pool correspond to intervals 0, 2, 4, 13, 14 and 15 in the DFN period, respectively.

Still, as shown in FIG. 8, the network side device configures the transmission resource of the configured direct connection permission in the resource pool. The three intervals of the configured direct connection permission period represent three intervals in the resource pool.

If nrofHARQ-Processes=4 and harq-procID-offset=0 are configured, then the HARQ process IDs corresponding to the configured forward connection enable are 0, 1, 2 and 3, respectively. In this embodiment, the HARQ process IDs corresponding to the configured forward connection grant transmission resources at positions in the time domain such as slot 2, slot 5, slot 8, slot 11, slot 14 and slot 17, etc. are respectively 0, 1, 2, 3, 0 and 1, etc.

In the process of determining the ID of the first hybrid automatic retransmission request process according to the time domain information corresponding to the configured direct connection permission transmission resource, the network side device configures the configured direct connection permission transmission resource for the terminal. According to the position in the time domain of the transmission resource of the configured direct connection grant on the direct connection, the corresponding ID of the first HARQ process can be determined by the following formula.

HARQ process ID = [floor (CURRENT_slot × 10/(numberOfSlotsPerFrame × periodicity))] mod nrofHARQ-Processes + harq-procID-offset.

In the above formula, mod represents the modulo operation and floor represents the round down operation.

Optionally, in action S91, determining the time domain information corresponding to the transmission resource of the configured direct connection permission based on the first configuration information may include the following operating actions S910 and S912.

In action S910, an uplink control channel sent by the terminal in an uplink transmission resource is received based on the first configuration information, wherein the uplink transmission resource and the configured forward connection permission transmission resource belong to the same configured forward connection permission period, and the channel The uplink control is used for the terminal to communicate forward connection feedback information.

In action S912, the time domain information corresponding to the transmission resource of the configured direct connection grant is determined according to the time domain information of the uplink transmission resource.

In the process of configuring the configured forward connection grant, the network side device also configures an uplink transmission resource for PUCCH transmission, so that in each configured forward connection grant period, there is a corresponding PUCCH transmission resource. The terminal device sends forward connection feedback information to the network side device via PUCCH. After receiving the PUCCH sent by the terminal device in the uplink transmission resource, the network side device can determine the position in the time domain of the transmission resource of the configured direct connection grant in the same period as the PUCCH, according to the PUCCH, and further can determine the HARQ process ID corresponding transmission resource configured to enable direct connection according to the above formula.

Optionally, the above method may further include the following actuation S94.

In action S94, at least one of the following parameters is determined: a first parameter and a second parameter; wherein the first parameter is used to determine a time interval between the uplink transmission resource and the forward connection reverse channel transmission resource, and the second parameter is used to determine the time interval between the forward connection reverse channel transmission resource and the configured forward connection grant transmission resource.

The PUCCH slot resource is an slot in an SFN period, and the transmission resource slot of a configured direct connection grant is an slot in an SFN period (or a DFN period). The time domain information of the transmission resource of the configured forward connection grant is determined according to the SFN index (or DFN index) and the slot number in the radio frame. The uplink transmission resource is used to transmit the PUCCH, and its position in the time domain is determined by the SFN and the slot number in the radio frame. Optionally, the SFN period start interval and the DFN period start interval, i.e., SFN #0 and DFN #0, are not aligned and there is a time interval between them.

In fig. 10 is a schematic diagram of a time interval existing between an SFN period and a DFN period according to an optional embodiment of the present invention. As shown in FIG. 10, the network side device configures the forward link configured grant transmission resource and the PUCCH resource, and configures the forward link configured grant period to be 10 ms, which corresponds to four HARQ process IDs, which are 0, 1, 2 and 3, respectively. Both the forward link carrier subcarrier spacing and the uplink carrier subcarrier spacing are 15 kHz, i.e., each radio frame includes 10 slots. The transmission instant of the PUCCH determined according to the configuration information is instant T, in which case instant T corresponds to SFN #0 transmission resource interval 8 of the configured forward connection grant and corresponds to DFN #58 interval 6.

Optionally, the network side device may know the time interval between the forward connection transmission time and the uplink transmission time, since the network side device receives the PUCCH at time T, and the time domain position in the forward connection corresponding to the position T in the PUCCH time domain may be determined according to the position of T in the PUCCH time domain.

It should be noted that the forward connection configured permission transmission resource associated with the PUCCH is the forward connection configured permission transmission resource in the same forward connection configured permission period as the PUCCH. The forward connection feedback information corresponding to the forward connection data transmitted in the configured forward connection permission transmission resource in this period is reported to the network side device via a PUCCH associated with the configured forward connection permission transmission resource, that is, the PUCCH in this period.

Thus, the network side device needs to determine the time interval between the uplink transmission resource and the forward link reverse channel transmission resource and/or the time interval between the forward link reverse channel transmission resource and the configured forward link enable transmission resource.

Optionally, in action S912, determining the time domain information corresponding to the transmission resource of the configured direct connection grant according to the time domain information of the uplink transmission resource may include the following execution action S9120.

In action S9120, the time domain information corresponding to the transmission resource of the configured forward connection grant is determined according to the time domain information of the uplink transmission resource and at least one of the first parameter and the second parameter.

In an optional embodiment, the first configuration information is further used to configure at least one of an uplink transmission resource and a first parameter.

If a network-side device receives a PUCCH at time T, a time domain position corresponding to a physical feedforward link channel (abbreviated as PSFCH) is determined according to the time interval between the PUCCH transmission resource and the PSFCH transmission resource. Further, the network side apparatus may determine a position in a time domain of a forward connection transmission resource of a configured forward connection grant in a period in which the PSFCH is located, and further determine a HARQ process ID corresponding to the forward connection transmission resource corresponding to the PUCCH.

For example, the network side device configures a transmission resource of a configured direct connection grant for a terminal in a resource pool and configures a PUCCH transmission resource. The resource pool contains a PSFCH transmission resource, and the period of the PSFCH is two slots, namely, every two slots in the resource pool include a slot for transmitting a PSFCH, and the configured time slot between the PUCCH time domain resource and the PSFCH is three slots. That is, when receiving the PUCCH, the network side device can determine the slot position of the PSFCH corresponding to the PUCCH according to the slot position of the PUCCH time domain resource. In an optional example, the slot position of the PSFCH is the slot in which the last PSFCH in the transmission resource period of the configured forward connection grant is located. That is, the network side device can determine the configured forward connection grant transmission resource interval in the period in which the PSFCH is located according to the PSFCH interval, and further can determine the HARQ process ID corresponding to the configured forward connection permission transmission resource.

That is, in the process of determining the HARQ process ID according to a position in the forward connection time domain corresponding to the transmission resource of the configured direct connection grant, the network side device can determine the forward connection HARQ process ID corresponding to the configured PUCCH transmission resource based on the time interval between direct connection and uplink.

Optionally, the above method may further include the following operating actions S95 and S96.

In action S95, second configuration information is sent to the terminal, wherein the second configuration information is used to configure a resource pool.

In action S96, the second parameter is determined according to the second configuration information.

In addition to sending the first configuration information to the terminal device, the network side device may also send second configuration information for configuring the resource pool to the terminal device. Additionally, a time interval between the forward connection feedback channel transmission resource and the configured forward connection enable transmission resource may be determined based on the second configuration information.

Optionally, the above method may further include the following actuation S97.

In action S97, downlink control information is sent to the terminal when the uplink control channel contains negative acknowledgment information, where the downlink control information is used to schedule a forward connection transmission resource, the downlink control information contains the ID of the first process of the hybrid automatic retransmission request, and downlink control information are used to schedule the terminal to retransmit the direct connection data corresponding to the ID of the first process of the hybrid automatic retransmission request in the direct connection transmission resource.

In transmitting the configured direct connection grant, the network side device may configure a PUCCH transmission resource for the terminal device. The terminal may report forward connection feedback information to the network side device in the PUCCH transmission resource. If the network side device receives the NACK feedback information reported by the terminal, the network side device dynamically allocates the retransmission resource for direct connection transmission over the DCI and indicates the ID of the first HARQ process in the DCI, so that the terminal device retransmits the first direct connection data to a forward link transmission resource scheduled by downlink control information. That is, the first HARQ process ID is contained in the DCI when the network-side device allocates a retransmission resource to the terminal device in a dynamic scheduling manner by the DCI, so that the terminal device can determine the first HARQ process ID corresponding to the retransmission resource scheduled by the DCI after receiving DCI.

Of course, in transmitting the configured direct connection grant, the network side device may not configure the PUCCH transmission resource for the terminal device. In this case, the terminal does not need to report forward connection feedback information to the network-side device, that is, retransmission is not required to be performed based on network scheduling. If the sending-side terminal receives a NACK on the PSFCH from the receiving-side terminal, the sending-side terminal may perform retransmission. However, in direct connection transmission, the sending-side terminal generally uses the transmission resource of the configured direct connection permission allocated by the network-side device. In this case, the HARQ process ID corresponding to the direct connection transmission is determined by the sending-side terminal itself and is not related to the position in the time domain of the transmission resource of the configured direct connection grant.

The embodiment also provides another information processing method running on the network side device. In fig. 11 is a flow diagram of another information processing method according to one embodiment of the present invention. As shown in FIG. 11, the method includes the following steps S1100 to S1102.

In action S1100, first configuration information is determined, wherein the first configuration information is used to configure an uplink transmission resource.

In action S1101, time domain information corresponding to the uplink transmission resource is determined based on the first configuration information.

In action S1102, the ID of the first hybrid automatic retransmission request process is determined according to the time domain information corresponding to the uplink transmission resource.

Unlike the information processing method shown in FIG. 9, in the information processing method shown in FIG. 11, the HARQ ID is no longer determined based on the time domain position of the forward link transmission resource, and the HARQ ID is determined based on the time domain position of the uplink transmission resource.

Optionally, the above method may further include the following operating actions S1103 and S1104.

In action S1103, the period parameter is determined based on the first configuration information, wherein the first configuration information is also used to configure the transmission resource of the configured direct connection permission, the transmission resource of the configured direct connection permission is used to transmit direct connection data, and the period parameter is used to determine the period of the transmission resource configured direct connection permission.

The configured direct connection permission transmission resource and the uplink transmission resource are connected, namely, forward connection feedback information corresponding to the direct connection data transmitted in the configured direct connection permission transmission resource is transmitted to the network side device in the uplink transmission resource.

In action S1104, the ID of the first hybrid automatic retransmission request process is determined according to the time domain information corresponding to the uplink transmission resource and the period parameter.

In the first configuration information, not only a transmission resource of the configured direct connection permission may be configured, but also an uplink transmission resource may be configured. The configured direct connection permission transmission resources configured by the network side device for the terminal device are periodic, with no more than N_max (N_max = 2 or 3) configured direct connection permission transmission resources included in each period, and one PUCCH transmission resource configured in each period. The terminal device transmits direct connection data using a transmission resource of the configured direct connection permission in a period, and reports direct connection feedback information to the network side device using a PUCCH transmission resource. Then, the network side device determines whether to allocate the retransmission resource to the terminal according to the forward connection feedback information.

Optionally, the time domain information corresponding to the configured direct connection permission transmission resource is an index of an interval of the configured direct connection permission transmission resource in the resource pool. The period parameter is represented by the number of intervals, and the number of intervals is the number of intervals in the resource pool or the number of potential intervals used for the resource pool.

A resource pool can be one of several resource pools. In particular, still, as shown in FIG. 8, a resource pool is determined within one SFN or DFN period as follows. Taking a subcarrier spacing of 15 kHz as an example, the DFN period includes 10240 subframes (or slots) corresponding to subframes 0, 1, 2, ... and 10239, respectively. Subframes that cannot be used for direct connection transmission, such as synchronization subframe, downlink subframe, special subframe (i.e., downlink subframe and special subframe in TDD system) and reserved subframe, are removed, and the number of remaining subframes is . The number of these remaining subframes can be divided by , bitmap repeats periodically in the remaining subframes, with a bit equal to 1 indicating that the subframe corresponding to the bit in the remaining subframes belongs to the resource pool, otherwise it does not belong to the resource pool.

The DFN period includes 10240 subframes, and the synchronization signal period is 160 ms. Assuming that two synchronization subframes are included in one synchronization period, therefore, there are 128 synchronization subframes in one DFN period, and the length of the bitmap to indicate the resource pool temporary domain resource is 10 bits. This requires two reserved subframes, and the number of remaining subframes is (10240-128-2=10110), which can be divided by the bitmap length of 10, so the remaining subframes are renumbered as 0, 1, 2, ... and 10109, where the first three bits of the bitmap are 1 and the remaining seven bits are 0. That is, in the remaining subframes, the first three subframes in every 10 subframes belong to the resource pool, and the remaining subframes do not belong to the resource pool. Since the bitmap needs to be repeated 1011 times in the remaining subframes to indicate that all subframes belong to the resource pool, and 3 subframes are included in each bitmap period, a total of 3033 subframes belong to the resource pool in one DFN period. Each interval index in the resource pool corresponds to one interval index in the DFN period. For example, intervals 0, 1, 2, 3, 4 and 5 in the resource pool correspond to intervals 0, 2, 4, 13, 14 and 15 in the DFN period, respectively. The network-configured forward connection configured permission transmission resource will be associated with one resource pool, and the network-configured forward connection configured permission transmission resource is a transmission resource located in one resource pool.

In an embodiment, the time domain information corresponding to the configured direct connection grant transmission resource is an interval index of the configured direct connection permission transmission resource in the resource pool. For example, for the above embodiment, the resource pool in which the configured direct connection permission transmission resource is located includes 3033 subframes, so the time domain information corresponding to the configured direct connection permission transmission resource is an interval index in the resource pool, that is, an interval index in the range [ 0.3032].

Optionally, the time domain information corresponding to the transmission resource of the configured direct connection grant is an interval index in the intervals that are used for the resource pool. For example, for the above embodiment, the set of slots that are optionally used for the resource pool is the remaining subframes, and the corresponding slot index range is [0, 10109].

Optionally, the above method may further include the following actuation S1105.

In action S1105, downlink control information is sent to the terminal, wherein the downlink control information is used to schedule a forward connection transmission resource, and the downlink control information contains the ID of the first hybrid automatic retransmission request process.

In an optional embodiment, the terminal sends a negative acknowledgment to the network side device in the uplink transmission resource. When the network side device detects a negative acknowledgment in the uplink transmission resource, it sends downlink control information to the terminal, and the downlink control information contains the ID of the first HARQ process. After receiving the downlink control information, the terminal can obtain the first HARQ process ID based on the downlink control information.

In transmitting the configured direct connection grant, the network side device may configure a PUCCH transmission resource for the terminal device. The terminal may report forward connection feedback information to the network side device in the PUCCH transmission resource. If the network side device receives the NACK feedback information reported by the terminal, it dynamically allocates the retransmission resource for direct connection transmission by DCI and indicates the ID of the first HARQ process in DCI, so that the terminal device retransmits the first direct connection data in the direct connection transmission resource. direct connection scheduled by downlink control information. That is, the first HARQ process ID is contained in the DCI when the network side device allocates a retransmission resource to the terminal device in a dynamic scheduling manner by the DCI, so that the terminal device can determine the first HARQ process ID corresponding to the retransmission resource scheduled by the DCI after receiving DCI.

For example, a network-side device sends first configuration information to the terminal, and the first configuration information is used to configure a configured forward connection enable transmission resource and an uplink transmission resource. The terminal transmits direct connection data in a transmission resource of the configured direct connection permission. If the forward connection feedback information received by the terminal is a NACK, the terminal transmits the NACK to the network side device in the uplink transmission resource. Then, the network side device determines the ID of the first HARQ process according to the time domain position of the uplink transmission resource, and schedules the direct connection transmission resource for the terminal by means of the DCI for the terminal to retransmit the direct connection data. In this case, the ID of the first HARQ process is contained in the DCI. The terminal is responsible for receiving the DCI, and according to the ID of the first HARQ process, it can determine that the DCI is a network side device retransmission plan for the NACK transmitted in the uplink transmission resource. Also, the terminal may determine that the DCI is a retransmission plan for the direct connection data transmitted in the transmission resource of the configured direct connection grant associated with the uplink transmission resource, and thus the terminal retransmits the direct connection data in the forward connection transmission resource. direct connection scheduled via DCI.

Of course, in transmitting the configured direct connection grant, the network side device may not configure the PUCCH transmission resource for the terminal device. In this case, the terminal does not need to report forward connection feedback information to the network-side device, that is, retransmission is not required to be performed based on network scheduling. If the sending-side terminal receives a NACK on the PSFCH from the receiving-side terminal, the sending-side terminal may perform retransmission. However, in direct connection transmission, the sending-side terminal generally uses the transmission resource of the configured direct connection permission allocated by the network-side device. In this case, the HARQ process ID corresponding to the direct connection transmission is determined by the sending-side terminal itself and is not related to the position in the time domain of the transmission resource of the configured direct connection grant.

The embodiment also provides another information processing method that runs on a network-side device. In fig. 12 is a flow chart of yet another information processing method according to one embodiment of the present invention. As shown in FIG. 12, the method includes the following steps S1200 to S1202.

In action S1200, configuration information is received from a network side device, wherein the configuration information is used for an uplink transmission resource.

In action S1201, time domain information corresponding to the uplink transmission resource is determined based on the configuration information.

In action S1202, the ID of the first hybrid automatic retransmission request process is determined according to the time domain information corresponding to the uplink transmission resource.

Unlike the information processing method shown in FIG. 7, in the information processing method shown in FIG. 12, the HARQ ID is no longer determined based on the time domain position of the forward link transmission resource, and the HARQ ID is determined based on the time domain position of the uplink transmission resource.

Optionally, the configuration information is also used to configure a transmission resource of the configured direct connection enable for transmitting direct connection data.

In the configuration information, not only the transmission resource of the configured direct connection grant may be configured, but the PUCCH transmission resource may also be configured. Herein, the PUCCH transmission resource is the PUCCH resource corresponding to the configured direct connection permission transmission resource, that is, the forward connection feedback information associated with the direct connection data transmitted in the configured direct connection permission transmission resource is notified to the network side device by the resource PUCCH transmissions. For the terminal device, the ID of the first process of the hybrid automatic retransmission request may be determined according to a position in the time domain of the uplink transmission resource.

Optionally, the above method may further include the following actuation S1203.

In action S1203, at least one of the following parameters is determined: a first parameter and a second parameter; wherein the first parameter is used to determine a time interval between the uplink transmission resource and the forward connection reverse channel transmission resource, and the second parameter is used to determine the time interval between the forward connection reverse channel transmission resource and the configured forward connection grant transmission resource.

The PUCCH slot resource is an slot in the SFN period, and the transmission resource slot of the configured forward connection grant is an slot in the SFN period (or DFN period). The time domain information of the configured forward connection grant transmission resource is determined according to the SFN index (or DFN index) and the transmission resource interval number of the configured forward connection permission in the radio frame. The uplink transmission resource is used to transmit the PUCCH, and its position in the time domain is determined by the SFN and the slot number in the radio frame. Optionally, a period start interval SFN and a period start interval DFN, i.e. SFN #0 and DFN #0 are not aligned and there is a time gap between them.

It should be noted that the forward connection configured permission transmission resource associated with the PUCCH is the forward connection configured permission transmission resource in the same forward connection configured permission period as the PUCCH. The forward connection feedback information corresponding to the forward connection data transmitted in the configured forward connection permission transmission resource in this period is reported to the network side device via a PUCCH associated with the configured forward connection permission transmission resource, that is, the PUCCH in this period.

Thus, the network side device needs to determine the time interval between the uplink transmission resource and the forward link reverse channel transmission resource and/or the time interval between the forward link reverse channel transmission resource and the configured forward link enable transmission resource.

Optionally, the above method may further include the following operating actions S1204 and S1205.

In action S1204, the time domain information corresponding to the transmission resource of the configured direct connection grant is determined according to the time domain information of the uplink transmission resource and at least one of the first parameter and the second parameter, and the correspondence relationship between the uplink transmission resource and the transmission resource is obtained configured direct connection permission.

In action S1205, the configured direct connection permission transmission resource corresponding to the ID of the first hybrid automatic retransmission request process is determined according to the ID of the first hybrid automatic retransmission request process and the correspondence relationship between the uplink transmission resource and the configured direct connection permission transmission resource.

If the network side device receives the PUCCH at time T, the ID of the first hybrid automatic retransmission request process is determined according to the time domain resource of the PUCCH, and then the time domain position corresponding to the Physical Sidelink Feedback Channel (PSFCH), determined according to the time interval between the PUCCH transmission resource and the PSFCH transmission resource. Further, the network side device may determine a position in a time domain of a transmission resource of the configured forward connection grant in a period in which the PSFCH is located, and further determine a transmission resource of the configured forward connection grant corresponding to the ID of the first HARQ process.

For example, the network side device configures a transmission resource of a configured direct connection grant for a terminal in a resource pool and configures a PUCCH transmission resource. The resource pool contains a PSFCH transmission resource, and the period of the PSFCH is two slots, namely, every two slots in the resource pool include a slot for transmitting a PSFCH, and the configured time slot between the PUCCH time domain resource and the PSFCH is three slots. That is, when receiving the PUCCH, the network side device can determine the ID of the first HARQ process according to the slot position of the PUCCH time domain resource. Further, the network side apparatus determines the slot position of the PSFCH corresponding to the PUCCH according to the time interval between the PUCCH transmission resource and the PSFCH transmission resource.

That is, in the process of determining the HARQ process ID according to the position in the time domain of the PUCCH transmission resource, the network side device can determine the HARQ process ID corresponding to the configured transmission resource of the configured forward connection grant based on the time interval between the forward connection and the uplink.

Optionally, the above method may further include the following actuation S1206.

Optionally, the above method may further include the following operating actions S1207 and S1208.

In action S1207, downlink control information sent by the network side device is received, wherein the downlink control information is used to schedule a forward connection transmission resource, and the downlink control information contains the ID of the first hybrid automatic retransmission request process.

In action S1208, the first direct connection data is retransmitted in the forward connection transmission resource.

In transmitting the configured direct connection grant, the network side device may configure a PUCCH transmission resource for the terminal device. The terminal may report forward connection feedback information to the network side device in the PUCCH transmission resource.

Optionally, the network side device configures one PUCCH transmission resource in each configured forward connection enable period. In one configured forward connection enable period, the terminal sends first forward connection data to the receiving side terminal via a configured forward connection enable transmission resource that corresponds to the ID of the first HARQ process. If the terminal receives forward connection feedback information NACK sent by the receiving terminal, it will report the NACK to the network via PUCCH in the period. If the network side device receives the NACK feedback information reported by the terminal and the ID of the first HARQ process is determined according to the time domain position of the PUCCH transmission resource, the network side device dynamically allocates the retransmission resource for direct connection transmission via DCI and indicates the first process ID HARQ in DCI such that the terminal device retransmits the first direct connection data in the forward connection transmission resource scheduled by the downlink control information.

Additionally, the terminal may determine in advance a mapping relationship between the first HARQ process ID and the second HARQ process ID. The terminal device may transmit second direct connection data in a transmission resource of the configured direct connection permission using the second HARQ process ID based on the mapping relationship. The second forward connection data may include PSCCH and PSSCH. Additionally, the terminal device may also include a second HARQ process ID in the SCI, that is, the direct connection data transmitted on the PSSCH corresponds to the second HARQ process ID.

Optionally, the above method may further include the following actuation S1210.

In action S1210, a mapping relationship is determined between the ID of the first hybrid automatic retransmission request process and the ID of the second hybrid automatic retransmission request process.

Optionally, the above method may further include the following actuating actions S1211 and S1212.

In action S1212, the second direct connection data is retransmitted in the forward connection transmission resource based on the mapping relationship between the ID of the first hybrid automatic retransmission request process and the ID of the second hybrid automatic retransmission request process.

The network side apparatus determines the ID of the first HARQ process by the PUCCH transmission resource, and determines the process ID corresponding to the configured direct connection permission transmission resource as the first HARQ process ID according to the correspondence relationship between the PUCCH and the configured direct connection permission transmission resource. When a network-side device receives a NACK, the retransmission resource is dynamically allocated for direct connection transmission via the DCI, and the ID of the first HARQ process is specified in the DCI. After receiving the DCI and obtaining the first HARQ process ID from the DCI, the terminal device may determine that the retransmission resource is a retransmission scheduling for direct connection transmission of the second HARQ process ID according to the mapping relationship between the first HARQ process ID and the second HARQ process ID.

It can be seen that the ID of the first HARQ process determined by the terminal device according to the time domain information of the configured direct connection permission transmission resource may be different from the ID of the second HARQ process used when data is transmitted using the configured direct connection permission transmission resource, and the terminal device may also determine a mapping relationship between the first HARQ process ID and the second HARQ process ID, so that the terminal device has greater flexibility or autonomy to determine the HARQ process ID for transmission over the direct connection.

The embodiment also provides another information processing method that runs on the terminal device.

The first process ID of the hybrid automatic retransmission request is determined according to the following formula.

HARQ process ID = [floor (CURRENT_slot/periodicity)] mod nrofHARQ-Processes + harq-procID-offset.

In this document, the meanings of the various parameters in this formula are as follows.

(1) CURRENT_slot represents the transmission resource slot index of the configured direct connection enable. Additionally, the parameter represents the interval index within the radio frame period. The range of values for this parameter is [0, N-1]. N represents the total number of slots contained in a radio frame period. For example, for a subcarrier spacing of 15 kHz, a radio frame contains 10 slots, and a radio frame period contains 10240 slots, hence the range of values for this parameter is [0, 10239].

(2) periodicity represents the transmission resource period of the configured direct connection enable. Optionally, the parameter is represented by a time period such as 100 ms, 200 ms, and 500 ms. The parameter is optionally represented by the number of intervals. Additionally, the parameter is represented by the number of physical intervals. For example, periodicity=100 intervals, 200 intervals, etc. In the case of a subcarrier spacing of 15 kHz, a period of 100 ms can correspond to 100 slots. In the case of a subcarrier spacing of 30 kHz, a period of 100 ms may correspond to 200 intervals, and so on.

(3) nrofHARQ-Processes represents the total number of HARQ process IDs corresponding to the configured direct connection enable.

(4) harq-procID-offset is used to determine the ID of the first HARQ process corresponding to the configured direct connection enable. Optional, if the network side device does not configure the parameter, the parameter value is 0.

In the above formula, mod represents the modulo operation and floor represents the round down operation.

In an optional embodiment, the terminal receives configuration information from the network side device and determines an interval where the configured forward connection permission transmission resource is located according to the configuration information.

Optionally, at least one of the following parameters may be determined by the above configuration information: (1) the transmission resource period of the configured direct connection enable; (2) the total number of HARQ process IDs corresponding to the currently configured resolution; (3) a HARQ process ID offset used to determine the ID of the first HARQ process corresponding to the currently configured resolution; (4) an interval corresponding to the time domain resource of the transmission resource of the configured direct connection permission.

In an optional embodiment, the configuration information includes information indicating an interval offset, information indicating a time domain resource, and a period parameter. The transmission resource of the configured direct connection grant is determined based on the interval offset indicating information, the time domain resource indicating information, and the period parameter. The interval offset indicating information is used to determine the time domain information of the first transmission resource of the configured forward connection grant in the system frame number period (or in the forward frame number period). Optionally, the slot offset information is represented by a number of physical slots. The time domain resource indicating information is used to determine the position in the time domain of the transmission resource of the configured direct connection permission configured in the configured direct connection permission period, for example, one, two or three values are determined according to the time domain resource indicating information, and these values represent intervals positions in the time domain of the transmission resources of the configured direct connection permission relative to the position in the time domain determined according to the interval offset indicating information. For example, if two values determined according to the time domain resource indicating information are 3 and 7, respectively, and the time domain position determined according to the slot offset indicating information is slot 1, the slots in which the transmission resources of the configured direct grant are located connections are slots 4 and 8. The period parameter is used to determine the transmission resource period of the configured direct connection enable and is represented by a time period or number of physical slots.

For example, the terminal receives configuration information sent by the network to configure transmission resources of the configured direct connection permission, and the transmission resource intervals of the configured direct connection permission determined according to the configuration information are: interval 2, 102, 202, 302, 402, 502, 602 , 702, 802, etc. The configured direct connection enable period is 100 slots, including three HARQ process IDs, and the HARQ process ID offset is 0. Therefore, the HARQ process IDs corresponding to the configured direct connection enable are 0, 1, and 2. Thus, the HARQ process IDs corresponding to various transmission resources of the configured direct connection permission are determined according to the above formula. Table 1 shows the mapping relationship between the transmission resources of the configured direct connection grant and the HARQ process ID. Table 1 is shown below.

The terminal device may use the second HARQ process ID to transmit the first direct connection data. The terminal determines the correspondence relationship between the ID of the first HARQ process and the ID of the second HARQ process. The first forward connection data may include PSCCH and PSSCH. Additionally, the terminal device may also include the second HARQ process ID in the forward connection control information (SCI), that is, the forward connection data transmitted on the PSSCH corresponds to the second HARQ process ID.

Optionally, the network side device configures one PUCCH transmission resource in each configured forward connection enable period. In the configured direct connection enable period, the terminal sends the first direct connection data to the receiving side terminal through the configured forward connection permission transmission resource. If the forward connection feedback information sent by the receiving side terminal located on the terminal is NACK, the terminal reports the NACK to the network side device via PUCCH in a period. According to the PUCCH transmission resource, the device on the network side can determine a position in the time domain of the configured direct connection grant transmission resource corresponding to the PUCCH to determine the HARQ process ID corresponding to the direct connection data transmitted in the configured direct connection grant transmission resource, namely, the ID of the first HARQ process . If the network-side device receives the NACK feedback information reported by the terminal, it dynamically allocates the retransmission resource for direct connection transmission over the DCI, and indicates the ID of the first HARQ process in the DCI, so that the terminal device retransmits the first direct connection data in the transmission resource over a direct connection scheduled by downlink control information.

Optionally, the above method may further include the following executive actions.

In the first action, the terminal receives the DCI from the network side device, wherein the DCI is used for forward connection transmission resource scheduling, and the downlink control information contains the ID of the first HARQ process.

The range of values for this parameter is [0, N-1]. N represents the total number of slots contained in a radio frame period.
