Before introducing the technical solution of this application, the relevant knowledge of this application will be described below:

Side communication: Side communication is direct communication between terminals. Fig. 1 shows a schematic structural diagram of a lateral communication system provided by an exemplary embodiment of the present application. The lateral communication system includes a first terminal 110 , a second terminal 120 and a network device 130 .

In side communication, according to the coverage of the network device 130 where the communicating terminal is located, it can be divided into side communication within the coverage of the network device 130, side communication covered by part of the network device 130, and outside the coverage of the network device 130. The sidewalk communication is described in detail as follows:

(a) in FIG. 1 : that is, side communication within the coverage of the network device 130 . In the lateral communication between the first terminal 110 and the second terminal 120 within the coverage of the network device 130, both the first terminal 110 and the second terminal 120 are within the corresponding coverage of the same network device. At this time, both the first terminal 110 and the second terminal 120 may perform sidelink communication based on the same sidelink configuration by receiving configuration signaling from the network device 130 .

(b) in FIG. 1 : that is, side communication covered by part of the network device 130 . The first terminal 110 is within the coverage of the network device 130 , the second terminal 120 is not within the coverage of the network device 130 , and some terminals performing lateral communication are within the coverage of the network device 130 . At this time, the first terminal 110 can receive the configuration signaling of the network device 130 and perform side communication according to the configuration signaling; while the second terminal 120 cannot receive the configuration signaling of the network device 130 . In this case, the terminal outside the coverage of the network device 130 (that is, the second terminal 120) will send the The information carried in the Physical Sidelink Broadcast Channel (Physical Sidelink Broadcast Channel, PSBCH) determines the sidelink configuration for sidelink communication.

(c) in FIG. 1 : that is, side communication outside the coverage of the network device 130 . Both the first terminal 110 and the second terminal 120 are outside the coverage of the network device 130 , and both the first terminal 110 and the second terminal 120 determine a sidelink configuration according to pre-configuration information to perform sidelink communication.

Device to Device/Vehicle to Everything (D2D/V2X):

Device-to-device communication is a sidelink transmission technology based on D2D. It is different from the way communication data is received or sent by network equipment in traditional cellular systems, so it has higher spectral efficiency and lower transmission delay. Taking the Internet of Vehicles system as an example, the Internet of Vehicles system adopts a terminal-to-terminal direct communication method, and two transmission modes are defined in 3GPP: the first mode and the second mode.

The first mode: The transmission resources of the terminal are allocated by the network equipment, and the terminal sends data on the sidelink according to the resources allocated by the network equipment; the network equipment can allocate resources for a single transmission to the terminal, and can also allocate resources for the terminal Resources for semi-static transfers. As shown in (a) of FIG. 1 , the first terminal 110 and the second terminal 120 are located within the coverage of the network device 130, and the network device 130 allocates transmission resources ( i.e. sideline transmission resources).

The second mode: the terminal selects a resource in the resource pool (Resource Pool, RP) for data transmission. As shown in (c) of Figure 1, the first terminal 110 and the second terminal 120 are located outside the coverage of the network device 130, and the first terminal 110 and the second terminal 120 can independently select transmission resources from the pre-configured resource pool performing sidelink transmission; or as shown in (a) of FIG. 1 , the first terminal 110 and the second terminal 120 autonomously select transmission resources from the resource pool configured for them by the network device 130 to perform sidelink transmission.

NR-V2X: Taking the terminal as a vehicle as an example, in NR-V2X, due to the need to support automatic driving, higher requirements are placed on the data interaction between vehicles, such as higher throughput, lower delay, Higher reliability, larger coverage, more flexible resource allocation, etc.

In Long Term Evolution (Long Term Evaluation, LTE), the data interaction between vehicles mainly supports the broadcast transmission mode. FIG. For example, it specifically includes the following three broadcast transmission methods:

(a) in Fig. 2: Unicast propagation mode. For unicast transmission, there is only one terminal at the receiving end. That is, unicast transmission is performed between the sending terminal 210 and one receiving terminal 220 .

(b) in Fig. 2: multicast propagation mode. Multiple receiver terminals 220 form a communication group, the sender terminal 210 sends data, and other terminals in the group are all receiver terminals.

(c) in Fig. 2: broadcast transmission mode. For broadcast transmission, the receiving terminal 220 is any terminal around the transmitting terminal 210 .

In NR-V2X, unicast and multicast transmission methods are introduced, for details, please refer to the foregoing content.

NR-V2X system frame structure: Figure 3 shows the time slot structure in NR-V2X, which is specifically described as follows:

(a) in Figure 3 represents a time slot structure that does not include a physical sidelink feedback channel (Physical Sidelink Feedback Channel, PSFCH) channel in a time slot; Figure (b) in Figure 3 represents a time slot structure that includes a PSFCH channel.

Exemplarily, the physical sidelink control channel (Physical Sidelink Control Channel, PSCCH) in NR-V2X starts from the second sidelink symbol that can be used for sidelink transmission in the time slot, occupying 2 or 3 OFDM symbols can occupy {10, 12, 15, 20, 25} physical resource blocks (Physical Resource Block, PRB) in the frequency domain. In order to avoid blind detection of the PSCCH by the terminal, only one number of PSCCH symbols and one number of PRBs are allowed to be configured in one resource pool.

In addition, because the subchannel is the minimum granularity of resource allocation in the frequency domain of the Physical Sidelink Shaerd Channel (PSSCH) in NR-V2X, the number of PRBs occupied by the PSCCH must be less than or equal to the number of PRBs contained in a subchannel in the resource pool. The number of PRBs, so as not to impose additional restrictions on PSSCH resource selection or allocation.

As shown in (a) of FIG. 3 , exemplary, the PSSCH also starts from the second sidelink symbol available for sidelink transmission in the time slot in the time domain, and the last time domain symbol in the time slot is The guard interval is the GP symbol, and the remaining symbols are mapped to the PSSCH. The first side row symbol in this time slot is the repetition of the second side row symbol. Usually, the receiving terminal uses the first side row symbol as an automatic gain control (Automatic Gain Control, AGC) symbol. Data is generally not used for data demodulation. The PSSCH occupies K sub-channels in the frequency domain, and each sub-channel includes N consecutive PRBs.

As shown in (b) of Figure 3, when a time slot contains a PSFCH channel, the second-to-last and third-to-last symbols in the time slot are used for PSFCH channel transmission, and a time domain symbol before the PSFCH channel is used as a GP symbol.

The second-order sidelink control information (Sidelink Control Information, SCI) mechanism in NR-V2X:

The second-order SCI is introduced in NR-V2X. The first-order SCI is carried in the PSCCH to indicate the transmission resources of the PSSCH, reserved resource information, MCS level, priority and other information. The second-order SCI is sent in the resources of the PSSCH , using the DMRS of the PSSCH to perform demodulation, and used to indicate information for data demodulation, such as the sending end ID, receiving end ID, HARQ ID, and NDI.

Fig. 4 shows a schematic diagram of resource mapping of the second-order SCI. Among them, the second-order SCI is mapped from the first demodulation reference signal (Demodulation Reference Signal, DMRS) symbol of the PSSCH, first in the frequency domain and then in the time domain. Specifically, the PSCCH occupies 3 symbols (symbols 1, 2, 3), and the DMRS of the PSSCH occupies symbols 4 and 11. The second-order SCI is mapped from symbol 4, and frequency division multiplexed with DMRS on symbol 4. The second-order The SCI is mapped to symbols 4, 5, and 6, and the resource size occupied by the second-order SCI depends on the number of bits of the second-order SCI.

Side feedback channel: In NR-V2X, in order to improve reliability, a side feedback channel is introduced. For example, for unicast transmission, the transmitting terminal sends sidelink data (including PSCCH and PSSCH) to the receiving terminal, and the receiving terminal sends HARQ feedback information (including ACK or NACK) to the transmitting terminal, and the transmitting terminal transmits HARQ feedback information (including ACK or NACK) to the transmitting terminal. The feedback information judges whether retransmission is required. Wherein, the HARQ feedback information is carried in a sidelink feedback channel, such as PSFCH.

Optionally, sidelink feedback is activated or deactivated through pre-configuration information, network device configuration information, or the sending terminal.

Specifically, if the sidelink feedback is activated, the receiving terminal receives the sidelink data sent by the transmitting terminal, and feeds back HARQ ACK or NACK to the transmitting terminal according to the detection result, and the transmitting terminal decides to send retransmission data according to the feedback information of the receiving terminal or new data. If the sidelink feedback is deactivated, the receiving terminal does not need to send feedback information, and the transmitting terminal usually sends data in the form of blind retransmission. For example, the transmitting terminal repeats sending K times for each sidelink data, instead of receiving The end-terminal feedback information determines whether to send retransmission data.

Format of the sidewalk feedback channel:

In NR-V2X, PSFCH is introduced. The PSFCH only carries 1-bit HARQ-ACK information and occupies 2 time-domain symbols in the time domain. The second symbol carries sideline feedback information, and the data on the first symbol is a copy of the data on the second symbol, but the first symbol is used as AGC and occupies 1 PRB in the frequency domain.

FIG. 5 shows a schematic diagram of a time slot structure of sidelink transmission resources, in which the positions of time domain symbols occupied by PSFCH, PSCCH, and PSSCH in a time slot are schematically shown.

In a slot, the last symbol is used as GP; the penultimate symbol is used for PSFCH transmission; the penultimate symbol data is the same as the PSFCH symbol data, which is used as AGC; the penultimate symbol is also used as GP; The first symbol in the time slot is used as AGC, and the data on this symbol is the same as the data on the second time domain symbol in the time slot; PSCCH occupies 3 time domain symbols; the remaining symbols can be used for PSSCH transmission.

Resources for sidewalk feedback channels:

In order to reduce the overhead of the PSFCH channel, a time slot in every N time slots is defined to include PSFCH transmission resources, that is, the period of the sidelink feedback resource is N time slots, where N=1, 2, 4, and the parameter N is the preset configuration or network device configuration. Schematically, when N=4, transmission of sidelink transmission resources is shown in FIG. 6 .

Among them, the feedback information of the PSSCH transmitted in time slots 2, 3, 4, and 5 is all transmitted in time slot 7, so the time slot {2, 3, 4, 5} can be regarded as a time slot set, For the PSSCH transmitted in the time slot set, the corresponding PSFCH is in the same time slot.

In addition, the resource of the sidelink feedback channel may be determined according to the time slot to which the PSSCH belongs and the starting position of the occupied subband. When N=4, FIG. 7 shows a schematic diagram of the corresponding relationship of sidelink transmission resources. Wherein, the PSSCHs transmitted in the same subband starting position in different time slots respectively correspond to different PSFCH resources in the feedback time slots.

Resource pool (ResourcePool, RP):

A resource pool is a collection of resources. The resource pool of the sidelink is a collection of time-frequency resources used for sidelink transmission. The resource pool of the sidelink can be configured through pre-configuration information or network configuration information.

Specifically, the sending terminal sends PSCCH/PSSCH in the sending resource pool configured for it, and the receiving terminal detects whether there is a PSCCH/PSSCH sent by other terminals in the receiving resource pool configured for it. If detected, the receiving terminal The transmission resource for sending the PSFCH is determined according to the transmission resource of the PSCCH/PSSCH and the configuration information of the PSFCH in the receiving resource pool.

After sending the PSCCH/PSSCH, the transmitting terminal determines resources for receiving the PSFCH according to the PSFCH configuration information in the sending resource pool, and performs PSFCH detection. In order to enable the sending terminal and the receiving terminal to perform data transmission normally, the sending resource pool configured for the sending terminal is generally the same as the receiving resource pool configured for the receiving terminal. Therefore, the sending terminal and the receiving terminal can determine the same PSFCH transmission resource according to the PSSCH transmission resource and the configuration information of PSFCH in their respective resource pools.

Mini-slot transmission:

In the Rel-15NR Uu interface transmission system, micro-slot transmission or scheduling is introduced, that is, the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) or physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) scheduled by the network equipment is not The time slot is used as the granularity, but the time domain symbols in the time slot are used as the granularity, so that the purpose of reducing the time delay can be achieved.

Fig. 8 shows a schematic diagram of scheduling of mini-slots. Among them, the Physical Downlink Control Channel (PDCCH) located at the head of the time slot can not only schedule the PDSCH located in the same time slot (with mini-slot 1 as the resource unit), but also schedule the PUSCH located at the end of the time slot (mini-slot 2 is used as a resource unit), so that uplink and downlink data can be quickly scheduled within one time slot.

In the NR system, it supports mini-slot scheduling with {2, 4, 7} time-domain symbols as the time-domain scheduling granularity.

Fig. 9 shows a flowchart of a method for determining sidelink transmission resources provided by an exemplary embodiment of the present application.

The embodiment of the present application is illustrated by taking the above method applied to the lateral communication system shown in FIG. 1 as an example. The lateral communication system includes a terminal and a network device, and the method is applied to the terminal. The method for determining the lateral transmission resource provided in the embodiment of the present application includes the following steps:

Step 102: The terminal receives the configuration signaling sent by the network device.

Configuration signaling may also be referred to as scheduling signaling. Optionally, the configuration signaling is radio resource control (Radio Resource Control, RRC) signaling or downlink control information (Downlink Control Information, DCI).

Schematically, the configuration signaling is used to determine time domain positions of one or more sidelink transmission resources.

Schematically, the first mini-slot interval is used to determine the first time-domain position of the first sidelink transmission resource, and the first time-domain position is determined based on the time-domain position received from the configuration signaling and the first mini-slot interval of.

• Configuration information for determining the second mini-slot interval.

The second mini-slot interval is used to indicate the number of mini-slots separated between the mini-slot to which the mth sidelink transmission resource belongs and the mini-slot to which the first sidelink transmission resource belongs. Schematically, the second mini-slot interval is used to determine the mini-slot to which the m-th sidelink transmission resource belongs, and the mini-slot to which the m-th sidelink transmission resource belongs is based on the time domain of the first sidelink transmission resource The location and the second mini-slot interval are determined. Wherein, m is an integer greater than 1.

Wherein, a mini-slot includes one or more time-domain symbols in a slot, and a slot may include multiple mini-slots. Specifically, the number of mini-slots in one time slot can be set according to actual needs, which is not limited in this application. Optionally, a time slot includes 2 mini-slots, and the indication information in the configuration signaling indicates that the time domain position of the first sidelink transmission resource is the first (or second) mini-slot in the time slot. time slot.

Optionally, the configuration signaling includes first signaling, and the first signaling includes but is not limited to at least one of the following information: configuration information for determining the interval of the first mini-slot, configuration information for determining the interval of the second mini-slot Interval configuration information and position information of the first sidelink transmission resource on the time slot to which it belongs.

For example, if the configuration signaling is DCI as an example, the terminal receives the DCI sent by the network device, and the time interval field of the DCI carries the index value of the first mini-slot interval, and the index value is used to determine the first sidelink transmission resource The number of mini-slots between the mini-slot to which the DCI belongs and the mini-slot to which the DCI belongs; at the same time, the DCI also carries first indication information, and the first indication information is used to indicate the second mini-slot interval, and the terminal can Determine the mini-slots to which other side-line transmission resources except the first side-line transmission resource belong, and the mini-slots to which other side-line transmission resources except the first side-line transmission resource belong The mini-slot to which the transmission resource belongs and the second mini-slot interval are determined.

For another example, a time slot includes two mini-slots, and the terminal receives the DCI sent by the network device, and the time interval field of the DCI carries an index value of the time slot interval, and the index value is used to determine the to which the first sidelink transmission resource belongs. The number of time slots between the time slot of the DCI and the time slot to which the DCI belongs; at the same time, the DCI also carries indication information, which is used to indicate that the first sidelink transmission resource corresponds to the second in the time slot to which it belongs. mini-slots.

Step 104: the terminal determines the time domain position of the sidelink transmission resource according to the configuration signaling.

Schematically, the sidelink transmission resources are used for sidelink transmission based on mini-slots; or, the sidelink transmission resources are transmission resources with a scheduling granularity of mini-slots; or, the sidelink transmission resources are used for sidelink micro-slots. time slot transmission.

Wherein, a mini-slot includes one or more time-domain symbols in a slot, and a slot may include multiple mini-slots. For example, one slot includes two mini-slots. Specifically, the number of mini-slots in one time slot can be set according to actual needs, which is not limited in this application.

According to the foregoing, the sidelink transmission resource is used to transmit at least one of the following: PSCCH, PSSCH, and PSFCH; the configuration signaling carries information related to the mini-slot to which the sidelink transmission resource belongs, including but not limited to the following At least one of the information: configuration information for determining the interval of the first mini-slot, configuration information for determining the interval of the second mini-slot, and position information of the first sidelink transmission resource on the associated time slot. Wherein, the first mini-slot interval refers to the number of mini-slots separated between the mini-slot to which the first sidelink transmission resource belongs and the mini-slot to which the configuration signaling belongs, or is used to indicate that the first sidelink The number of mini-slots between the mini-slots to which the transmission resources belong and the reference SFN; the second mini-slot interval refers to the mini-slots and the second mini-slots to which other sideline transmission resources except the first sideline transmission resources belong The number of mini-slots between the mini-slots to which the side-line transmission resource belongs.

Take the configuration signaling as DCI as an example, where the time interval field of DCI carries the first index value of the first mini-slot interval, and the first index value is used to determine the mini-slot to which the first sidelink transmission resource belongs The number of minislots separated from the minislot to which the DCI belongs. After receiving the DCI sent by the network device, the terminal can uniquely determine the time-domain position of the first sidelink transmission resource according to the mini-slot to which the DCI belongs and the number of intervals corresponding to the first index value. The time-domain position corresponds to a mini-slot.

Schematically, the determination of the time domain position of the first sidelink transmission resource can be determined through the time interval (Time gap) field in the configuration signaling.

The time interval is used to determine the time slot interval between the first side transmission resource and the time slot or mini-slot where the configuration signaling is located, and the first side transmission resource can be determined according to this information and the time domain position where the terminal receives the configuration signaling. The time domain location of the row transmission resource. Wherein, the first sidelink transmission resource may be in a time slot or in a mini-slot.

Optionally, take the configuration signaling as DCI as an example. The network device configures the time interval table through the parameter sl-DCI-ToSL-Trans. The elements in the table represent the number of time slots or mini-slots. The DCI The parameter is an index value, and the specific time interval size can be determined according to the index value and the time interval table.

Specifically, after receiving the DCI, the terminal determines the size of the specific time interval according to the parameter sl-DCI-ToSL-Trans and the time interval table, and then, according to the time domain position of the DCI and the size of the time interval, determines the first The temporal location of the sidelink transmission resource.

Optionally, the determination of the time domain position of the first sidelink transmission resource may also be determined through the time interval (sl-TimeOffsetCG-Type1) field in the configuration signaling.

Wherein, the time interval is used to determine the time interval between the first sidelink transmission resource and the reference SFN (sl-TimeReferenceSFN-Type1), and this parameter is expressed as the number of mini-slots. The time domain position of the first sidelink transmission resource can be determined according to the information and the time domain position of the reference SFN.

Among the sidelink transmission resources allocated by the network device to the terminal, there may be more than one sidelink transmission resource, and the time domain position of each sidelink transmission resource needs to be determined. After determining the time domain position of the first sidelink transmission resource, the terminal may determine the time domain positions of the remaining sidelink transmission resources according to the time domain position of the first sidelink transmission resource and the second mini-slot interval. It should be understood that when the sidelink transmission resources allocated by the network device to the terminal include N sidelink transmission resources, the second mini-slot interval includes N-1 mini-slot intervals, corresponding to The mini-slot interval between the other N-1 sidelink transmission resources and the first sidelink transmission resource.

Schematically, the time domain positions of other sidelink transmission resources except the first sidelink transmission resource can be determined by configuring a time domain resource assignment (Time resource assignment) field in the signaling.

Among them, the method of time domain resource allocation for indicating time domain resources is the same as that of SCI format 1-A, and the value of this parameter is represented by Time Resource Indication Value (TRIV), which is used to determine The time slot interval or mini-slot interval of the other N-1 sideline transmission resources other than the first sideline transmission resource relative to the first sideline transmission resource. In this application, the determination of the mini-slot intervals of the N-1 sidelink transmission resources except the first sidelink transmission resource relative to the first sidelink transmission resource through TRIV is taken as an example.

Based on the time domain position of the first transmission resource determined in the foregoing content, combined with this information, the time domain positions of the remaining N−1 transmission resources can be determined.

Exemplarily, the relationship between the value of TRIV and the number N of sidelink transmission resources allocated by the network device is as follows:

if N=1: TRIV=0;

If N=2: TRIV=t ₁ ;

If N=3:

When (t ₂ -t ₁ -1)≤15: TRIV=30(t ₂ -t ₁ -1)+t ₁ +31;

Otherwise: TRIV=30( _{t2 -} t1-1)+ _t1 +31;

Among them, t ₂ and t ₁ represent the time intervals of the second and third transmission resources relative to the first transmission resource respectively, represented by the number of mini-slots, when N=2, 1≤t ₁ ≤ 31; when N=3, 1≤t ₁ ≤30, t_1<t ₂ ≤31.

Taking N as 3 as an example, the timing of N (N=1, 2, or 3) sidelink transmission resources allocated by the network device to the terminal can be determined by combining the above two information and the time slot to which the signaling belongs. domain location.

Exemplarily, taking the configuration signaling as DCI as an example, FIG. 10 shows a schematic diagram of time slot intervals of sidelink transmission resources. Among them, DCI allocates 3 sideline transmission resources, and allocates PUCCH transmission resources, as follows:

A represents the time interval between the mini-slot to which the DCI belongs (i.e. mini-slot n) and the first sidelink transmission resource, which is determined by the time interval field in the DCI;

t ₁ represents the mini-slot interval between the allocated second sidelink transmission resource and the first sidelink transmission resource, which is determined according to the time domain resource allocation field in DCI;

t ₂ represents the mini-slot interval between the allocated third sidelink transmission resource and the first sidelink transmission resource, which is determined according to the time domain resource allocation field in the DCI.

As another example, the configuration signaling is still DCI as an example, where the DCI carries indication information A and indication information B, where the indication information A is used to indicate the distance between the first sidelink transmission resource and the time slot where the DCI is located. Time interval, according to the indication information A and the position of the time slot where the DCI is located, the time slot to which the first sideline transmission resource belongs can be determined, and the indication information B is used to indicate the microtime of the first sideline transmission resource on the time slot to which it belongs Gap position. After receiving the DCI sent by the network device, the terminal can determine the time domain position of the sidelink transmission resource according to the time slot to which the sidelink transmission resource belongs and the indication information B, and the time domain position corresponds to a mini-slot.

To sum up, in the method for determining sidelink transmission resources provided by the embodiment of the present application, by using mini-slots as the granularity, the terminal determines the time domain position corresponding to the sidelink transmission resources according to the configuration signaling. In the sidelink communication scenario The transmission scheduling of micro-slot granularity is realized, and the transmission delay is reduced.

The lateral communication system includes a terminal and a network device, and the method is applied to the network device. The method for sending lateral transmission resources provided in the embodiment of the present application includes the following steps:

Step 202: the network device sends configuration signaling to the terminal.

Schematically, the configuration signaling is used to determine time domain positions of one or more sidelink transmission resources.

Schematically, the sidelink transmission resources are used for sidelink transmission based on mini-slots; or, the sidelink transmission resources are transmission resources with a scheduling granularity of mini-slots; or, the sidelink transmission resources are used for sidelink micro-slots. time slot transmission.

According to the foregoing, the sidelink transmission resource is used to transmit at least one of the following: PSCCH, PSSCH, and PSFCH; the configuration signaling carries information related to the mini-slot to which the sidelink transmission resource belongs, including but not limited to the following At least one of the information: configuration information for determining the interval of the first mini-slot, configuration information for determining the interval of the second mini-slot, and position information of the first sidelink transmission resource on the associated time slot.

Optionally, the configuration signaling is RRC signaling.

Step 204: the terminal receives the configuration signaling.

According to the foregoing content, the terminal can acquire at least one of the following information according to the received configuration signaling: configuration information for determining the first mini-slot interval, configuration information for determining the second mini-slot interval, configuration information for the second mini-slot interval, The location information of a sidelink transmission resource on the time slot to which it belongs.

For example, if the configuration signaling is DCI as an example, the DCI sent by the network device to the terminal carries the index value of the first mini-slot interval in the time interval field of the DCI, and the index value is used to determine the first sidelink transmission resource The number of mini-slots between the mini-slot to which the DCI belongs and the mini-slot to which the DCI belongs; at the same time, the DCI also carries first indication information, and the first indication information is used to indicate the second mini-slot interval, and the terminal can Determine the mini-slots to which other side-line transmission resources except the first side-line transmission resource belong, and the mini-slots to which other side-line transmission resources except the first side-line transmission resource belong The mini-slot to which the transmission resource belongs and the second mini-slot interval are determined.

For another example, a time slot includes two mini-slots, and the terminal receives the DCI sent by the network device, and the time interval field of the DCI carries an index value of the time slot interval, and the index value is used to determine the to which the first sidelink transmission resource belongs. The number of mini-slots between the time slot of the DCI and the time slot to which the DCI belongs; at the same time, the DCI also carries indication information, which is used to indicate that the first sidelink transmission resource corresponds to the first sidelink transmission resource in the time slot to which it belongs. 2 mini-slots.

To sum up, in the method for sending sidelink transmission resources provided by the embodiment of the present application, by sending configuration signaling, the terminal can determine the time domain position corresponding to the sidelink transmission resource at the granularity of the micro-slot. The transmission scheduling at the micro-slot granularity is realized, and the transmission delay is reduced.

Fig. 12 shows a flowchart of a method for transmitting sidelink transmission resources provided by an exemplary embodiment of the present application. In this embodiment of the present application, the transmission method of the sidelink transmission resources is applied to the sidelink communication system shown in FIG. 1 as an example. The sidelink communication system includes terminals and network devices, and the configuration signaling includes the first signaling as an example. The method for transmitting sidelink transmission resources provided in the embodiment of the present application includes the following steps:

Step 301: The network device sends a second signaling to the terminal.

Schematically, the second signaling is used to configure the mini-slot interval set. Wherein, the set of mini-slot intervals includes at least one candidate mini-slot interval.

Optionally, the second signaling is RRC signaling, and the mini-slot interval set is carried in the parameter sl-DCI-ToSL-Trans.

Step 302: The terminal receives the second signaling.

After receiving the second signaling, the terminal can acquire the mini-slot interval set.

Exemplarily, taking the second signaling as the RRC signaling as an example, the network device sends the RRC signaling to the terminal, and the signaling includes the parameter sl-DCI-ToSL-Trans. Wherein, the parameter sl-DCI-ToSL-Trans={1, 2, 4, 6, 8, 12, 16, 32}.

After receiving the second signaling, the terminal can obtain a set of mini-slot intervals as {1, 2, 4, 6, 8, 12, 16, 32}. Wherein, the mini-slot interval set includes eight candidate mini-slot intervals.

Specifically, the first candidate mini-slot interval means that the interval between the mini-slot to which the first sidelink transmission resource belongs and the mini-slot to which the first signaling belongs is one mini-slot, and the second candidate The mini-slot interval refers to that the interval between the mini-slot to which the first sidelink transmission resource belongs and the mini-slot to which the first signaling belongs is 2 mini-slots, and the third candidate mini-slot interval refers to The interval between the mini-slot to which the first sidelink transmission resource belongs and the mini-slot to which the first signaling belongs is 4 mini-slots, and the fourth candidate mini-slot interval refers to the first sidelink transmission resource The interval between the mini-slot to which the first signaling belongs and the mini-slot to which the first signaling belongs is 6 mini-slots, and the fifth candidate mini-slot interval refers to the distance between the mini-slot to which the first sidelink transmission resource belongs and the first The number of intervals between the mini-slots to which a signaling belongs is 8 mini-slots, and the sixth candidate mini-slot interval refers to the mini-slot to which the first sidelink transmission resource belongs and the micro-slot to which the first signaling belongs. The number of slot intervals is 12 mini-slots, and the seventh candidate mini-slot interval means that the interval between the mini-slot to which the first sidelink transmission resource belongs and the mini-slot to which the first signaling belongs is 16 The mini-slot, the eighth candidate mini-slot interval means that the interval between the mini-slot to which the first sidelink transmission resource belongs and the mini-slot to which the first signaling belongs is 32 mini-slots.

Schematically, step 301 and step 302 are optional steps. That is, during the transmission of the sidelink transmission resource, the second signaling may be received before the current transmission, or may be received during the current transmission.

Step 303: The network device sends the first signaling to the terminal.

Schematically, the first signaling carries information related to the first mini-slot interval.

Wherein, the relevant information of the first mini-slot interval is used to determine the first mini-slot interval.

The first mini-slot interval is used to indicate the number of mini-slots separated between the mini-slot to which the first sidelink transmission resource belongs and the mini-slot to which the configuration signaling belongs. For example, if the configuration signaling includes the first signaling as an example, and the first mini-slot interval is 3, the interval between the mini-slot to which the first sidelink transmission resource belongs and the mini-slot to which the first signaling belongs is 3 mini-slots.

Optionally, the information about the first mini-slot interval includes a first index value of the first mini-slot interval. Wherein, the first index value is used to determine the first mini-slot interval in the mini-slot interval set.

Schematically, the value j of the first index value is used to indicate that the first mini-slot interval is the jth mini-slot interval in the mini-slot interval set.

Based on this, the terminal determines the number of mini-slots between the mini-slot to which the first sidelink transmission resource belongs and the mini-slot to which the first signaling belongs, and the number of intervals is determined according to the first index value.

Schematically, the first signaling carries mini-slot interval indication information, and the time-domain position of the first sidelink transmission resource can be determined according to the mini-slot interval indication information. For example, the mini-slot interval indication information is used to indicate the number of mini-slots separated between the time domain position of the first sidelink transmission resource and the time domain position of the reference SFN.

Step 304: The terminal receives the first signaling.

When the first signaling carries the first index value of the first mini-slot interval, the terminal may acquire the first index value after receiving the first signaling.

Taking the information about the first mini-slot interval including the first index value of the first mini-slot interval, and the first index value being 3 as an example, the network device sends the first signaling to the terminal, and the first signaling carried in the first signaling An index value is 3, and after receiving the first signaling, the terminal may determine that the first index value is 3 according to the first signaling.

Schematically, the first signaling is a configuration signaling sent by the network device to the terminal.

Optionally, the first signaling is DCI, and the first index value is carried in a time interval (Time gap) field of the DCI.

Taking the first signaling as DCI, the first index value carried in the time interval field of DCI is 2 (assuming that the index value starts from 0), and the mini-slot interval set includes the interval number of 5 mini-slots as an example, 5 The interval numbers of mini-slots are 1, 2, 4, 6, 8, respectively.

Wherein, the mini-slot interval set includes five candidate mini-slot intervals, and the first candidate mini-slot interval refers to the mini-slot to which the first sidelink transmission resource belongs and the mini-slot to which the first signaling belongs. The number of slot intervals is 1 mini-slot, and the second candidate mini-slot interval means that the interval between the mini-slot to which the first sidelink transmission resource belongs and the mini-slot to which the first signaling belongs is 2 The third candidate mini-slot interval means that the interval between the mini-slot to which the first sidelink transmission resource belongs and the mini-slot to which the first signaling belongs is 4 mini-slots.

After receiving the DCI, the terminal can obtain the first index value 2. Since the index value starts from 0, the index value 2 corresponds to the third index value in the sequence number of the index value. According to the first index value, the terminal determines that the interval number of the corresponding mini-slot is 4 in the mini-slot interval set. The terminal determines in the mini-slot interval set according to the first index value that the mini-slot to which the first sidelink transmission resource belongs is different from the mini-slot to which the first signaling belongs by 4 mini-slots.

Wherein, the mini-slot interval set may be obtained according to step 301 and step 302, or may be obtained before the transmission of the sidelink transmission resource this time.

Step 305: the terminal determines the first mini-slot interval according to the relevant information of the first mini-slot interval.

According to the foregoing content, the relevant information of the first mini-slot interval may optionally include the first index value of the first mini-slot interval, based on which, the terminal may determine the first mini-slot interval. In the following, it is taken as an example that the relevant information of the first mini-slot interval includes the first index value of the first mini-slot interval.

Based on this, the optional implementation of step 305 is as follows:

The terminal determines the first slot interval in the mini-slot interval set according to the relevant information of the first mini-slot interval.

Schematically, the first mini-slot interval is used to determine the first time-domain position of the first sidelink transmission resource, and the first mini-slot interval is the ith candidate mini-slot interval in the mini-slot interval set , i is determined according to the first index value.

According to step 301 and step 302, the terminal can obtain the mini-slot interval set; according to step 303 and step 304, the terminal can obtain the first index value. Based on this, the terminal may determine the first mini-slot interval in the mini-slot interval set according to the first index value.

Taking the first index value as 2 (assuming that the index value starts from 0) and the set of mini-slot intervals as {1, 2, 4, 6, 8} as an example, the terminal determines the first mini-slot interval according to the first index value is the third candidate mini-slot interval in the set of mini-slot intervals. That is, the first mini-slot interval is 4.

Step 306: the terminal determines a first time domain position of the first sidelink transmission resource.

Schematically, the first time domain position is determined based on the second time domain position and the first mini-slot interval, the second time domain position is the time domain position for receiving the first signaling, or the second time domain position is Refer to the time domain location corresponding to the SFN.

It should be understood that when the second time domain position is the time domain position corresponding to the reference SFN, the terminal may determine the first mini-slot interval according to the first signaling sent by the network device, further, according to the time domain position of the reference SFN and the The first mini-slot interval determines the first time domain position corresponding to the first sidelink transmission resource.

Wherein, the time interval indicated by the first signaling is based on the mini-slot granularity.

Specifically, after determining the first mini-slot interval, the terminal may determine the first time-domain position of the first sidelink transmission resource according to the first mini-slot interval.

Taking n as the first mini-slot interval as an example, the embodiment of the present application provides the following two optional methods for determining the first time domain position:

Determination mode 1: the first time domain position is a time domain position separated by n mini-slots after the second time domain position.

Referring to FIG. 13 , one time slot includes two mini-slots, and the terminal receives the first signaling sent by the network device in mini-slot 3, and the first signaling is carried in the PDCCH. That is, the first signaling is on mini-slot 3.

Take for example that the first index value is 2 (assuming that the index value starts from 0), and the set of mini-slot intervals is {1, 2, 4, 6, 8, 12, 16, 32}. According to the foregoing content, after receiving the first index value, the terminal may determine that the first mini-slot interval is 4 in the mini-slot interval set according to the first index value, that is, n=4.

According to the mini-slot 3 and the first mini-slot interval, the terminal can determine the first time domain position. Specifically, the time-domain position of mini-slot 3 after 4 mini-slots is the mini-slot to which the first sidelink transmission resource belongs. That is, according to determination mode 1, it may be determined that the first time domain position is mini-slot 7 .

Determination mode 2: the first time domain position is a time domain position separated by n logic mini-slots after the second time domain position.

Schematically, the first signaling also carries a first resource pool index, the first resource pool index is used to indicate the first target resource pool, the logical mini-slot is a mini-slot belonging to the first target resource pool, and the first The temporal location belongs to the first target resource pool.

Wherein, the resource pool refers to a resource set composed of schedulable resources of the terminal, and the resource pool limits the time-frequency resource range of the sidelink communication.

Referring to FIG. 14 , one time slot includes two mini-slots, and the terminal receives the first signaling sent by the network device in mini-slot 3, and the first signaling is carried in the PDCCH.

In addition, the network device configures two resource pools for the terminal, namely resource pool 1 and resource pool 2. Resource pool 1 includes mini-slots with even indexes, resource pool 2 includes mini-slots with odd indexes, and mini-slots 3 belongs to the mini-slot in resource pool 2.

Also take the example that the first index value is 2 (assuming that the index value starts from 0), and the set of mini-slot intervals is {1, 2, 4, 6, 8, 12, 16, 32}. According to the foregoing content, after receiving the first index value, the terminal may determine that the first mini-slot interval is 4 in the mini-slot interval set according to the first index value, that is, n=4.

Meanwhile, since the first signaling also carries the first resource pool index, the terminal can determine that the first target resource pool is the resource pool 2 according to the first resource pool index. According to the foregoing, the logical mini-slots belong to the mini-slots in the resource pool 2 .

Based on this, according to the first resource pool index, mini-slot 3 and the first mini-slot interval, the terminal can determine the first time domain position. Specifically, since the first target resource pool is resource pool 2, mini-slot 3 is in The time-domain positions separated by 4 logical mini-slots are the mini-slots to which the first sidelink transmission resource belongs. That is, according to determination mode 2, it may be determined that the first time domain position is mini-slot 11 .

Step 307: the terminal determines the time domain position of the mth sidelink transmission resource.

Schematically, the first signaling also carries first indication information, the first indication information is used to indicate the second mini-slot interval, and the time domain position of the mth sidelink transmission resource is based on the first time domain position and the second mini-slot interval is determined. Optionally, the first signaling is DCI or RRC, and the second mini-slot interval is carried in the time-domain resource allocation field of DCI or RRC, which can be represented by TRIV.

Wherein, the second mini-slot interval is used to indicate the number of mini-slots between the mini-slot to which the mth sidelink transmission resource belongs and the mini-slot to which the first sidelink transmission resource belongs, that is, to indicate The mini-slot interval of the m-th sidelink transmission resource relative to the first sidelink transmission resource, where m is an integer greater than 1.

After determining the time-domain position of the first sidelink transmission resource, the terminal needs to determine the time-domain positions of the remaining sidelink transmission resources. In step 307, the time domain position of the mth sidelink transmission resource is determined through the second mini-slot interval. Taking the second mini-slot interval expressed by TRIV as an example, the relationship between TRIV and the number of sidelink transmission resources can refer to the relational expression given in the foregoing content, or be set according to actual needs. Do limited.

Taking the number of sidelink transmission resources as 3 as an example, after determining the time domain position of the first sidelink transmission resource, the time domain of the second and third sidelink transmission resources can be determined according to t ₁ and t ₂ Location. Among them, t ₁ represents the mini-slot interval between the second sideline transmission resource and the first sideline transmission resource, and t ₂ represents the interval between the third sideline transmission resource and the first sideline transmission resource the mini-slot interval.

Optionally, in the case that the first signaling also carries the first resource pool index, the time domain position of the mth sideline transmission resource is a time domain spaced by p logic mini-slots after the first time domain position Location. Wherein, the first resource pool index is used to indicate the first target resource pool, p is the second mini-slot interval, the logical mini-slot is a mini-slot belonging to the first target resource pool, and the first time domain position belongs to the first Target resource pool, p is an integer not less than 0.

Schematically, in the embodiment of the present application, the steps on the terminal side can be independently an embodiment of a method for determining sidelink transmission resources, and the steps on the network device side can be independently an embodiment of a method for sending sidelink transmission resources , the specific explanation of the steps of the method for determining the sidelink transmission resources and the steps of the sending method can refer to the above content, and will not be repeated here.

To sum up, the sidelink transmission resource determination method and sending method provided by the embodiment of the present application enable the terminal to determine the first mini-slot interval by carrying information about the first mini-slot interval in the first signaling , so as to determine the mini-slot to which the first sidelink transmission resource belongs; at the same time, the terminal determines the mini-slots to which the remaining sidelink transmission resources belong according to the mini-slot to which the first sidelink transmission resource belongs. Optionally, the information about the first mini-slot interval includes a first index value of the first mini-slot interval, and the terminal determines the first mini-slot interval in the mini-slot interval set according to the index value, thereby determining the first Mini-slots to which sidelink transmission resources belong.

Fig. 15 shows a flowchart of another method for transmitting sidelink transmission resources provided by an exemplary embodiment of the present application.

In this embodiment of the present application, the transmission method of the sidelink transmission resources is applied to the sidelink communication system shown in FIG. 1 as an example. The sidelink communication system includes terminals and network devices, and the configuration signaling includes the first signaling as an example. The method for transmitting sidelink transmission resources provided in the embodiment of the present application includes the following steps:

Step 401: The network device sends the first signaling to the terminal.

Schematically, the first signaling carries the second indication information and the third indication information.

Schematically, the second indication information is used to indicate the time interval between the time slot to which the first sidelink transmission resource belongs and the reference SFN.

Taking the first signaling as DCI as an example, the terminal receives the DCI sent by the network device, and the time interval field of the DCI carries the second indication information, and the second indication information includes the second index value of the first time slot interval, and the second index The value is used to determine the number of slots between the slot to which the first sidelink transmission resource belongs and the slot to which the DCI belongs.

In addition, the third indication information is used to indicate the mini-slot position of the first sidelink transmission resource in the corresponding time slot.

Optionally, the third indication information includes an N-bit information field, and the N-bit information field is used to indicate the position of the mini-slot in the time slot. Wherein, the value of N depends on the maximum number of mini-slots included in a time slot. For example, if one time slot includes two mini-slots, then N=1; for another example, if one time slot includes four mini-slots, then N=2. In the case that a time slot includes two mini-slots, the first signaling includes a 1-bit information field, which is used to indicate the first mini-slot in the time slot when the value of the information field is 0. When the value of this information field is 1, it is used to indicate the second mini-slot in the time slot.

Step 403: The terminal determines the first time slot to which the first sidelink transmission resource belongs according to the second indication information.

According to the foregoing content, the second indication information is used to indicate the number of time slots between the time slot to which the first sidelink transmission resource belongs and the time slot to which the first signaling belongs.

Based on this, after receiving the first signaling, the terminal may obtain the second indication information, and determine the time slot position corresponding to the first sidelink transmission resource according to the second indication information.

Optionally, the second indication information includes related information of the first time slot interval, and the related information is used to determine the first time slot mentioned in the first sidelink transmission resource. For example, the second indication information includes a second index value of the first time slot interval, and the terminal determines the first time slot according to the index value.

Taking the first signaling as DCI as an example, the DCI time interval field carries a second index value of the first time slot interval, and the second index value is used to determine the time slot to which the first sidelink transmission resource belongs and the time slot to which the first sidelink transmission resource belongs. The number of slots between the slots to which the DCI belongs. After receiving the DCI sent by the network device, the terminal can uniquely determine the time slot to which the first sidelink transmission resource belongs according to the time slot to which the DCI belongs and the number of intervals corresponding to the first index value, which is the first time slot. Gap.

Step 404: The terminal determines the ith mini-slot of the first sidelink transmission resource in the first time slot according to the third indication information.

According to the foregoing content, the third indication information is used to indicate the mini-slot position of the first sidelink transmission resource in the corresponding time slot.

Based on this, after receiving the first signaling, the terminal may obtain the third indication information, and determine according to the third indication information that the first sidelink transmission resource is at the end of the i-th mini-slot in the first time slot.

Specifically, taking the example that the first time slot includes at least two mini-slots, the terminal may determine the mini-slot position of the first sidelink transmission resource in the at least two mini-slots according to the third indication information. For example, the third indication information is used to indicate that the first sidelink transmission resource corresponds to the second mini-slot in the time slot to which it belongs.

Step 405: the terminal determines the mini-slot to which the mth sidelink transmission resource belongs.

Schematically, the first signaling also carries fourth indication information, which is used to indicate the second mini-slot interval, and the mini-slot to which the mth sideline transmission resource belongs is based on the The time domain position of the row transmission resource and the interval of the second mini-slot are determined. Wherein, m is an integer greater than 1, and the time-domain position of the first sidelink transmission resource is a mini-slot position.

Optionally, the first signaling is DCI or RRC, and the second mini-slot interval is carried in the time-domain resource allocation field of DCI or RRC, which can be represented by TRIV.

Wherein, the second mini-slot interval is used to indicate the mini-slot interval of the mth sidelink transmission resource relative to the first sidelink transmission resource, and m is an integer greater than 1.

Among the sidelink transmission resources allocated by the network device to the terminal, there may be more than one sidelink transmission resource, and the time domain position of each sidelink transmission resource needs to be determined. After the mini-slot to which the first sidelink transmission resource belongs is determined, it is also necessary to determine the mini-slots to which the remaining sidelink transmission resources belong.

In step 405, the terminal may determine the mini-slot to which the m-th sidelink transmission resource belongs according to the second mini-slot interval, where m is an integer greater than 1. It should be understood that when the sidelink transmission resources allocated by the network device to the terminal include N sidelink transmission resources, the second mini-slot interval includes N-1 mini-slot intervals, corresponding to The mini-slot interval between the other N-1 sidelink transmission resources and the first sidelink transmission resource. Taking the second mini-slot interval expressed by TRIV as an example, the relationship between TRVI and the number of sidelink transmission resources can refer to the relational expression given in the foregoing content, or be set according to actual needs, and this application does not Do limited.

Taking the number of sidelink transmission resources as 3 as an example, after determining the mini-slot to which the first sidelink transmission resource belongs, the mini-slots to which the second and third sidelink transmission resources belong can be determined according to _t1 and _t2 . mini-slot. Among them, t ₁ represents the mini-slot interval between the second sideline transmission resource and the first sideline transmission resource, and t ₂ represents the interval between the third sideline transmission resource and the first sideline transmission resource the mini-slot interval.

Optionally, in the case that the first signaling also carries the second resource pool index, the mini-slot to which the mth sidelink transmission resource belongs is r intervals after the time domain position of the first sidelink transmission resource Time domain position of the logical mini-slot, m is an integer greater than 1. Wherein, the second resource pool index is used to indicate the second target resource pool, r is the second mini-slot interval, the logical mini-slot is a mini-slot belonging to the second target resource pool, and the first sidelink transmission resource The temporal location belongs to the second target resource pool.

To sum up, the method for determining and sending sidelink transmission resources provided by the embodiments of the present application enables the terminal to use the second indication information and the third indication information carried in the first signaling to enable the terminal to The third indication information determines the mini-slot to which the first sidelink transmission resource belongs; at the same time, the terminal determines the mini-slots to which the remaining sidelink transmission resources belong according to the mini-slot to which the first sidelink transmission resource belongs.

Fig. 16 shows a flowchart of another method for transmitting sidelink transmission resources provided by an exemplary embodiment of the present application. In this embodiment of the present application, the transmission method of the sidelink transmission resources is applied to the sidelink communication system shown in FIG. 1 as an example. The sidelink communication system includes terminals and network devices, and the configuration signaling includes the first signaling as an example. The method for transmitting sidelink transmission resources provided in the embodiment of the present application includes the following steps:

Step 501: The network device sends second signaling to the terminal.

Schematically, the second signaling is used to configure a time slot interval set.

Optionally, the second signaling is RRC signaling, and the time slot interval set is carried in the parameter sl-DCI-ToSL-Trans.

Step 502: The terminal receives the second signaling.

After receiving the second signaling, the terminal may acquire the time slot interval set.

Exemplarily, taking the second signaling as the RRC signaling as an example, the network device sends the RRC signaling to the terminal, and the signaling includes the parameter sl-DCI-ToSL-Trans. Wherein, the parameter sl-DCI-ToSL-Trans={1, 2, 4, 6, 8, 12, 16, 32}.

After receiving the second signaling, the terminal can obtain a set of time slot intervals as {1, 2, 4, 6, 8, 12, 16, 32}. Wherein, the slot interval set includes eight candidate slot intervals.

Schematically, step 501 and step 502 are optional steps. That is, during the transmission of the sidelink transmission resource, the second signaling may be received before the current transmission, or may be received during the current transmission.

Step 503: The network device sends the first signaling to the terminal.

Schematically, the first signaling carries the second indication information and the third indication information. Wherein, the second indication information includes information related to the first time slot interval.

Wherein, the relevant information of the first time slot interval is used to determine the first time slot interval, so that the terminal can determine the first time slot to which the first sidelink transmission resource belongs.

According to the foregoing, the second indication information is used to determine the first time slot to which the first sidelink transmission resource belongs, and the third indication information is used to determine the i-th slot of the first sidelink transmission resource in the first time slot. Time slot, i is an integer not less than 0. Wherein, the second indication information is used to indicate the number of time slots between the time slot to which the first sideline transmission resource belongs and the time slot to which the first signaling belongs, or the second indication information is used to indicate that the first side The time interval between the time slot to which the row transmission resource belongs and the reference SFN; the third indication information is used to indicate the mini-slot position of the first side row transmission resource in the time slot to which it belongs.

Schematically, the first time slot interval is used to indicate the number of time slots between the first time slot to which the first sidelink transmission resource belongs and the time slot to which the configuration signaling belongs. For example, if the first time slot interval is 4, then there are 4 time slots between the first time slot and the time slot to which the first signaling belongs.

Optionally, the related information of the first time slot interval includes a second index value of the first time slot interval. Wherein, the second index value is used to determine the first slot interval in the slot interval set.

Schematically, the value k of the second index value is used to indicate that the first slot interval is the kth slot interval in the slot interval set.

Based on this, the terminal can determine the number of time slots between the time slot to which the first sidelink transmission resource belongs and the time slot to which the first signaling belongs, and the number of intervals is determined according to the second index value.

Schematically, the second index value is used to determine the first slot interval in the slot interval set, and the slot interval set includes at least one candidate slot interval. Schematically, the terminal determines the number of time slots between the time slot to which the first sidelink transmission resource belongs and the time slot to which the first signaling belongs in the time slot interval set according to the second index value.

Step 504: the terminal receives the first signaling.

Since the first signaling carries the second index value of the first time slot interval, the terminal may obtain the second index value after receiving the first signaling.

Taking the related information of the first time slot interval including the second index value of the first time slot interval, and the second index value being 3 as an example, the network device sends the first signaling to the terminal, and the second index carried in the first signaling The value is 3, and after receiving the first signaling, the terminal may determine that the second index value is 3 according to the first signaling.

Schematically, the first signaling is a configuration signaling sent by the network device to the terminal.

Optionally, the first signaling is DCI, and the second index value is carried in a time interval field of the DCI.

Taking the first signaling as DCI, and the second index value carried in the time interval field of DCI is 2 (assuming that the index value starts from 0) as an example, the time slot interval set includes the number of intervals of 5 time slots, each of which is 1 , 2, 4, 6, 8.

Wherein, the time slot interval set includes five candidate time slot intervals, and the first candidate time slot interval refers to the number of intervals between the time slot to which the first sidelink transmission resource belongs and the time slot to which the first signaling belongs is 1 time slot, the second candidate time slot interval refers to the interval between the time slot to which the first sidelink transmission resource belongs and the time slot to which the first signaling belongs is 2 time slots, and the third candidate The time slot interval means that the interval between the time slot to which the first sidelink transmission resource belongs and the time slot to which the first signaling belongs is 4 time slots.

After receiving the DCI, the terminal can obtain the second index value 2. Since the index value starts from 0, the index value 2 corresponds to the third index value in the sequence number of the index value. According to the second index value, the terminal determines that the interval number of the corresponding time slot is 4 in the time slot interval set. The terminal determines in the time slot interval set according to the second index value that the time slot to which the first sidelink transmission resource belongs is different from the time slot to which the first signaling belongs by 4 time slots.

Wherein, the time slot interval set may be obtained according to step 501 and step 502, or may be obtained before the transmission of the sidelink transmission resource this time.

Step 505: the terminal determines the first time slot interval according to the relevant information of the first time slot interval.

According to the foregoing content, the relevant information of the first time slot interval may optionally include the second index value of the first time slot interval, based on which, the terminal may determine the first time slot interval. In the following, it is taken as an example that the relevant information of the first time slot interval includes the second index value of the first time slot interval.

Based on this, the optional implementation of step 505 is as follows:

The terminal determines the first time slot interval in the time slot interval set according to the relevant information of the first time slot interval.

Schematically, the first time slot interval is used to determine the first time slot to which the first sidelink transmission resource belongs, and the first time slot interval is the ith candidate time slot interval in the time slot interval set, and i is based on the The second index value is determined.

According to step 501 and step 502, the terminal can obtain the second index value; according to step 503 and step 504, the terminal can obtain the time slot interval set. Based on this, the terminal may determine the first slot interval in the slot interval set according to the second index value.

Taking the second index value as 2 (assuming that the index value starts from 0), and the set of slot intervals is {1, 2, 4, 6, 8} as an example, the terminal determines the first slot in the set of slot intervals according to the second index value One slot interval is the third candidate slot interval. That is, the first slot interval is 4.

Step 506: the terminal determines the first time slot to which the first sidelink transmission resource belongs.

Schematically, the first time slot is determined based on the second time domain position and the first time slot interval, the second time domain position is the time domain position for receiving the first signaling, or the second time domain position is the reference SFN The corresponding time domain position.

It should be understood that when the second time domain position is the time domain position corresponding to the reference SFN, the terminal may determine the first time slot interval according to the first signaling sent by the network device, further, according to the time domain position of the reference SFN and the first time slot interval A time slot interval determines the time domain position corresponding to the first sidelink transmission resource.

Wherein, the time interval indicated by the first signaling is based on time slot granularity.

Specifically, after determining the first time slot interval, the terminal may determine the first time slot to which the first sidelink transmission resource belongs according to the first time slot interval.

Taking q as the first time slot interval as an example, the embodiment of this application provides the following two optional determination methods:

Determination mode 1: the first time slot is a time domain position separated by q time slots after the second time domain position.

That is, the terminal may determine the first time slot according to the time slot to which the first signaling belongs and the first time slot interval.

For example, the terminal receives the first signaling sent by the network device in time slot 3, that is, the first signaling is in time slot 3.

Take the second index value as 2 (assume that the index value starts from 0), and the set of time slot intervals is {1, 2, 4, 6, 8} as an example. According to the foregoing content, after receiving the second index value, the terminal may determine that the first time slot interval is 4 in the time slot interval set according to the second index value, that is, q=4. According to the time slot 3 and the first time slot interval, the terminal can determine the first time slot.

Specifically, according to determination method 1, it can be determined that the time domain position of time slot 3 after an interval of 4 time slots is the first time slot to which the first sidelink transmission resource belongs.

Determination mode 2: the first time slot is a time domain position separated by q logical time slots after the second time domain position.

Schematically, the first signaling also carries a second resource pool index, the second resource pool index is used to indicate the second target resource pool, the logical time slot is a time slot belonging to the second target resource pool, and the first time slot Belongs to the second target resource pool.

Wherein, the resource pool refers to a resource set composed of schedulable resources of the terminal, and the resource pool limits the time-frequency resource range of the sidelink communication.

For example, the terminal receives the first signaling sent by the network device at time slot 3, and the network device configures two resource pools for the terminal, namely resource pool 1 and resource pool 2, resource pool 1 includes time slots with even indexes, Resource pool 2 includes mini-slots with odd indexes, and time slot 3 belongs to the time slots in resource pool 2 .

Also take the second index value as 2 (assume that the index value starts from 0), and the set of time slot intervals is {1, 2, 4, 6, 8} as an example. According to the foregoing content, after receiving the second index value, the terminal may determine that the first time slot interval is 4 in the time slot interval set according to the second index value, that is, n=4.

Meanwhile, since the first signaling also carries the second resource pool index, the terminal can determine that the second target resource pool is the resource pool 2 according to the second resource pool index. According to the aforementioned content, the logical time slots belong to the time slots in the resource pool 2 .

Based on this, according to the second resource pool index, time slot 3, and the first time slot interval, the terminal can determine the first time slot. Specifically, it can be determined according to determination method 2. Since the second target resource pool is resource pool 2, the micro Time slot 3 is at a time domain position separated by 4 logical time slots, that is, the first time slot to which the first sidelink transmission resource belongs.

Step 507: The terminal determines the ith mini-slot of the first sidelink transmission resource in the first time slot according to the third indication information.

According to the foregoing content, the third indication information is used to indicate the mini-slot position of the first sidelink transmission resource in the corresponding time slot.

Based on this, after receiving the first signaling, the terminal may obtain the third indication information, and determine according to the third indication information that the first sidelink transmission resource is at the end of the i-th mini-slot in the first time slot.

Specifically, taking the example that the first time slot includes at least two mini-slots, the terminal may determine the specific mini-slot position of the first sidelink transmission resource in the at least two mini-slots according to the third indication information. For example, the third indication information is used to indicate that the first sidelink transmission resource corresponds to the second mini-slot in the time slot to which it belongs.

Step 508: the terminal determines the mini-slot to which the mth sidelink transmission resource belongs.

Schematically, the first signaling also carries fourth indication information, which is used to indicate the second mini-slot interval, and the mini-slot to which the mth sideline transmission resource belongs is based on the The time domain position of the row transmission resource and the interval of the second mini-slot are determined, and m is an integer greater than 1. Optionally, the first signaling is DCI or RRC, and the second mini-slot interval is carried in the time-domain resource allocation field of DCI or RRC, which can be represented by TRVI.

Wherein, the second mini-slot interval is used to indicate the mini-slot interval of the mth sidelink transmission resource relative to the first sidelink transmission resource, and m is an integer greater than 1.

Schematically, step 508 is the same as step 405, which can be used as a reference and will not be repeated here.

Schematically, in the embodiment of the present application, the steps on the terminal side can be independently an embodiment of a method for determining sidelink transmission resources, and the steps on the network device side can be independently an embodiment of a method for sending sidelink transmission resources , the specific explanation of the steps of the method for determining the sidelink transmission resources and the steps of the sending method can refer to the above content, and will not be repeated here.

To sum up, the sidelink transmission resource determination method and sending method provided by the embodiment of the present application enable the terminal to determine the first time slot interval by carrying the relevant information of the first time slot interval in the second indication information, thereby determining The time slot to which the first sideline transmission resource belongs, and then the terminal determines the mini-slot position of the first sideline transmission resource in the time slot to which it belongs through the third indication information; at the same time, the terminal The associated mini-slot determines the mini-slot to which the remaining sidelink transmission resources belong. Optionally, the information about the first slot interval includes a second index value of the first slot interval, and the terminal determines the first slot interval in the slot interval set according to the index value, thereby determining the first sidelink transmission The slot to which the resource belongs.
