Description

An information transmission method and its network element

technical field

The present invention relates to the field of communication technologies, and in particular, to an information transmission method and a network element thereof.

Background technique

For the Long Term Evolution (Long Term Evaluation, LTE) system, before data is uplinked, the user equipment needs to send a transmission scheduling request to the base station, and then the base station allocates uplink transmission resources to the user equipment according to the request, and sends the request to the user. Only after the device sends an uplink grant (UL grant) carrying the uplink transmission resource, the user equipment can use the uplink transmission resource for uplink data transmission. Therefore, in traditional LTE uplink data transmission, a certain time overhead will be generated from the time when the user equipment has an uplink data transmission requirement to when the eNB receives the uplink data transmission of the user equipment.

With the continuous development of communication technology, the ultra-reliable and low-latency communication technology of the fifth generation mobile communication technology (5G) has become the current mainstream trend. On the other hand, the use of Unlicensed Spectrum resources for data transmission is also One of the future data transmission trends. The corresponding coexistence specifications of the 5GHz unlicensed band resources include Transmit Power Control (TPC), Dynamic Frequency Selection (DFS), channel occupied bandwidth, and Listen before talk (LBT), etc. . Taking LBT as an example, if uplink data transmission is performed on unlicensed frequency band resources, both the user equipment and the base station need to compete for unlicensed spectrum resources through LBT. The more LBT times required, the greater the difficulty of transmission.

Uplink data transmission without uplink grant (UL grant free) is one of the future data transmission trends. Before transmitting uplink data through UL grant free, the user equipment does not need to wait for the dynamic scheduling indication information of the base station, which can not only reduce the time overhead of uplink data transmission, but also transmit on the unlicensed frequency band resources, which can also reduce the number of LBTs. On the other hand, in order to ensure the efficiency of uplink data transmission in the existing data transmission methods, the base station generally sends the uplink control information corresponding to the uplink data transmission to the user equipment dynamically, so as to realize link adaptation and thus ensure the efficiency of uplink data transmission. However, for the uplink data transmission mode based on UL grant free, the uplink data transmission of the user equipment no longer depends on the dynamic notification of the base station. Therefore, how to realize UL grant free transmission while ensuring the transmission efficiency of the uplink data and ensuring that the transmission of the uplink data can be adapted to the uplink transmission channel has become an urgent problem to be solved at present.

Detailed ways

The embodiments of the present invention can be applied to a wireless communication system, including an LTE system, a 4.5G wireless communication system or a 5G wireless communication system, and can be applied to a licensed spectrum or an unlicensed spectrum. When applied in a license-exempt spectrum, it can be used in an LTE system of Licensed Assisted Access (LAA), that is, an LAA-LTE system. The LTE system with assisted access to the licensed frequency band refers to an LTE system that uses a licensed frequency band and an unlicensed frequency band together through Carrier Aggregation (CA) or a non-CA manner. DC).

The LAA-LTE system corresponds to the scenario in which the licensed frequency band and the license-exempt frequency band are used jointly through carrier aggregation CA. The carrier included in the licensed frequency band or the cell operating in the unlicensed frequency band is used as the secondary cell, in which the primary cell and the secondary cell can be deployed in co-site or non-co-site deployment, and there is an ideal backhaul path between the two cells.

When the present invention is applied to the license-exempt frequency band, it is not limited to the above-mentioned CA scenario. Other deployment scenarios also include scenarios where there is no ideal backhaul path between two cells (primary cell and secondary cell), such as a large backhaul delay. , resulting in the inability to quickly coordinate information between the two cells, such as in a DC scenario. In addition, it can also be applied to independently deployed cells operating in the unlicensed frequency band, that is, the serving cell operating in the unlicensed frequency band can directly provide independent access functions without the assistance of cells operating in the licensed frequency band. For example, standalone LTE over unlicensed spectrum (Standalone ULTE) system.

In this embodiment of the present invention, network elements mainly refer to base stations and user equipments that can operate in a license-exempt frequency band. User equipment (User Equipment, UE) includes common user terminals such as mobile phones, tablet computers, etc., and may also include relay relays, that is, those that can perform data communication with the base station can be used as user equipment. Before introducing specific embodiments, some concepts such as base station, cell, spectrum, carrier, etc. involved in the present invention are briefly explained.

In this embodiment of the present invention, whether it is a licensed frequency band or an unlicensed frequency band, it can include one or more carriers, and the licensed frequency band and the unlicensed frequency band can perform carrier aggregation, and can include one or more carriers included in the licensed frequency band and the unlicensed frequency band. One or more carriers included in the frequency band are subjected to carrier aggregation.

In the present invention, the cell mentioned may be a cell corresponding to a base station, and a cell may belong to a macro base station or a base station corresponding to a small cell. The small cell here may include: a metro cell, a micro cell (Micro cell), pico cell (Pico cell), femto cell (Femto cell), etc. These small cells have the characteristics of small coverage and low transmit power, and are suitable for providing high-speed data transmission services.

A carrier in the LTE system can have multiple cells working on the same frequency at the same time. In some special scenarios, the concept of a carrier in the LTE system and a cell can also be considered equal. For example, in the CA scenario, when a secondary carrier is configured for the UE, the carrier index of the secondary carrier and the Cell Identification (Cell ID) of the secondary cell operating on the secondary carrier will be carried at the same time. In this case, it can be considered that The concepts of a carrier and a cell are equivalent, for example, the UE accessing a carrier is equivalent to accessing a cell. DC and standalone ULTE can also be based on this understanding. In the present invention, a cell will be taken as an example for introduction.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart of UL grant free transmission according to an embodiment of the present invention. In general, when the user equipment performs uplink data transmission, the user equipment needs to send a transmission scheduling request to the base station, and then the base station allocates uplink transmission resources to the user equipment according to the request, and sends the uplink transmission resources to the user equipment. The user equipment can use the uplink transmission resource for uplink data transmission. In the embodiment of the present invention, as shown in FIG. 1, UL grant free is used for data transmission, and the user equipment can determine the uplink control information without waiting for the dynamic scheduling indication information of the base station, and the uplink control information can be determined by the user equipment. After the information and uplink data are preprocessed, the preprocessed uplink control information and uplink data are sent to the base station through the physical uplink channel, which improves the transmission efficiency of the uplink data and ensures that the uplink data transmission can be adapted to the uplink transmission channel.

Please refer to FIG. 2, which is a schematic flowchart of an information transmission method provided by an embodiment of the present invention. As shown in FIG. 2, the information transmission method includes steps S101-S103.

S101, the user equipment determines uplink control information corresponding to the uplink data transmitted in the first time unit.

Specifically, when the user equipment has an uplink data transmission requirement, it may be determined to send the uplink data in the first time unit. In a possible embodiment, the time unit may be represented by a transmission time interval (Transmission TimeInterval, TTI), and the TTI may be measured by milliseconds (millisecond, ms), or by orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing) , OFDM) to measure, the time unit in the embodiment of the present invention is represented by TTI as an example. For example, 1 TTI may be 0.5ms, or 1 TTI may be 2 OFDM symbols. Wherein, the first time unit may be a time unit closest to the uplink transmission demand time of the user equipment, or may be a time unit delayed by a certain time range from the uplink transmission demand time of the user equipment. For example, considering that when the user equipment needs to perform uplink data transmission, it takes a certain amount of time to process the uplink data, such as encoding and modulation. Therefore, a certain delay time is required to process the uplink transmission data before the first time unit. As shown in FIG. 2a, FIG. 2a is a schematic diagram of uplink transmission data transmission provided by an embodiment of the present invention. The user equipment has an uplink data transmission requirement in the first TTI described in FIG. 2a, and then in the A time period The uplink data processing is performed within the first time period (the first time unit in FIG. 2a ), and the uplink data transmission is performed.

Optionally, in another possible embodiment, the first time unit may also be an uplink duration (Uplink duration, UL duration) on an unlicensed frequency band, and the UL duration may be pre-configured by the base station, such as The base station performs preconfiguration by sending a radio resource control (Radio Resource Control, RRC) signaling indication or a dynamic notification to the user equipment. Optionally, the UL duration can also be determined by the common control information indication on the licensed frequency band or the unlicensed frequency band, wherein the common control information can be transmitted through a common physical downlink control channel (CommonPhysicalDownlinkControlChannel, C-PDCCH), Or use the Cell Common Radio Network Temporary Identity (CC-RNTI) for scrambling, and the common control information can also be used to indicate the end position of downlink burst data transmission. As shown in FIG. 2b, FIG. 2b is a schematic diagram of a UL duration notified by a C-PDCCH in an unlicensed frequency band provided by an embodiment of the present invention, and the UL duration notified by the C-PDCCH may include a first time unit. Optionally, the UL duration and the downlink TTI where the C-PDCCH is located belong to the same transmission opportunity (Transmission Opportunity, TxOP), and TxOP may indicate that the device (such as user equipment or base station, etc.) is passing Clear Channel Assessments (Clear Channel Assessments, CCA) After (eg LBT) has competed for the opportunity to use the license-exempt frequency band resources, there is no need to re-evaluate the channel through CCA and continue to use the license-exempt frequency band. Therefore, the TxOP may include only the downlink time unit, or only the uplink time unit, or both the downlink time unit and the uplink time unit. The downlink time unit refers to a time unit for transmitting downlink data, and the uplink time unit refers to a time unit for transmitting uplink data. A time unit may include downlink data transmission and/or uplink data transmission, which is not limited herein. Optionally, the TxOP may also be a channel occupancy period (Channel Occupancy) or a maximum channel occupancy time (Maximum Channel Occupancy Time, MCOT). The downlink burst data transmission in FIG. 2b represents the time when the eNB performs downlink data transmission after competing for the unlicensed frequency band resource through CCA (eg LBT). The idle time unit therein may be used by the user equipment to perform CCA, but is not limited to this.

In this embodiment of the present invention, optionally, the first time unit may include transmission of uplink control information, or may not include transmission of uplink control information; in other words, the uplink control information may be transmitted through a physical uplink channel included in the first time unit transmission, or transmission through physical uplink channels included in other time units different from the first time unit.

In this embodiment of the present invention, the uplink data may be new transmission data or retransmission data, wherein, optionally, the new transmission data may be data transmission based on UL grant free, or the first new transmission data transmitted by the user equipment to the base station It is data transmission based on UL grant free, and the retransmitted data can be data transmission based on UL grant free or UL grant. For example, after the user equipment sends new transmission data to the base station based on UL grant free, and the base station receives the new transmission data but fails to process the new transmission data through demodulation or decoding, the base station will schedule the new transmission data based on the UL grant Retransmission. For another example, when the uplink transmission buffer is not zero, the user equipment transmits the first new transmission data to the base station based on the UL grant free, and the uplink data (new transmission data or retransmission data) transmitted after that are all based on the UL grant free. The UL grant is transmitted until the buffer of the user equipment is zero.

In this embodiment of the present invention, the uplink data may include uplink service data transmitted by the user equipment, and may also include uplink service data and an uplink reference signal transmitted by the user equipment, where the uplink reference signal may be used for demodulation of the uplink service data. The uplink control information may include hybrid automatic repeat request (HybridAutomatic Repeat Request, HARQ) information corresponding to the uplink data, wherein the HARQ information includes at least one of the following: HARQ Process Number (HARQ Process Number, HPN), new data indication ( New Data Indication, NDI) information, Redundancy Version (Redundancy Version, RV) information (used to accurately complete HARQ combining of uplink data). Optionally, the uplink control information only includes HARQ information. Optionally, the uplink control information may further include at least one of the following: modulation and coding scheme (Modulation Coding Scheme, MCS), resource allocation (Resource Allocation, RA) information, transmission block size (Transmission Block Size, TBS corresponding to uplink data) ), transmission power control (Transmission Power Control, TPC), user equipment identification (User Equipment Identification, UE ID) and the like. Optionally, more generally, the uplink control information based on UL grant free may also be called GCI (Grant-free Control Information). The content included in the downlink control information, taking the LTE system as an example, the GCI may include at least one item of uplink control information used in the UL grant. Format 0), DCI format 4, DCI format 0A, DCI format 0B, DCI format 4A, DCI format 4B to represent, but not limited to this.

Optionally, the above information may be preconfigured through RRC signaling sent by the base station, or may be predefined by the base station, but the uplink control information determined by the user equipment is selected by the user equipment and reported to the base station.

In this embodiment of the present invention, the HPN may be used to distinguish different uplink data. When the user performs uplink data transmission, in order to ensure the transmission efficiency of the uplink data, the base station will feed back an acknowledgment (Acknowledgement, ACK) or a non-acknowledgement (Non-Acknowledgement, ACK) to the user equipment after receiving the uplink data transmitted by the user equipment. NACK). Since it takes a certain time for the base station to demodulate or decode the uplink data, in order to improve the uplink transmission efficiency, the user equipment can continue to send the uplink data to the base station within the time range when the base station processes the uplink data. In order to facilitate the base station to identify different uplink data or perform HARQ combination processing on the uplink data, HPN can be introduced, and the user equipment reports the HPN to the base station, so that the base station can distinguish different uplink data transmitted by the user equipment according to the HPN. For example, at a certain moment, the base station performs ACK or NACK feedback for all received uplink data or uplink data for which ACK or NACK is not fed back. As shown in FIG. 2c, FIG. 2c is a schematic diagram of a base station feeding back multiple ACKs or NACKs at the same time according to an embodiment of the present invention. Uplink data and uplink data transmitted through PUSCH-2 are fed back with ACK or NACK at the fourth TTI, where the uplink data is carried in a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) for transmission. When the base station receives the HPN, it can distinguish different uplink data according to the HPN.

As shown in FIG. 2d, FIG. 2d is a schematic diagram of data transmission without NDI provided by an embodiment of the present invention. The user equipment sends the uplink data A in the first TTI and assumes that the HPN corresponding to the uplink data A is 1; the base station performs decoding and other operations after receiving the uplink data A, and determines that the uplink data A is received correctly and at a specific moment (such as the third TTI) to the user equipment for ACK feedback; if the user equipment does not receive ACK or receives ACK but is mistakenly detected as NACK, the user equipment will mistakenly believe that the base station has not received uplink data A or received uplink data A but decoded and other processing If it fails, at this time, the user equipment resends the uplink data A (assuming A') at a specific moment (eg, the fifth TTI), and the HPN corresponding to the uplink data A' is also 1 at this time. Assuming that the base station receives the uplink data A' in the fifth TTI, and since the base station has fed back the ACK to the uplink data A before, the base station will mistakenly believe that the uplink data A' is new data, so the data is processed Unnecessary data processing is performed during operations such as decoding.

As shown in FIG. 2e, FIG. 2e is a schematic diagram of another data transmission without NDI according to an embodiment of the present invention. The user equipment sends the uplink data A in the first TTI and assumes that the HPN corresponding to the uplink data A is 1; after the base station receives the uplink data A and undergoes decoding and other processing, it determines that the uplink data A is received incorrectly. At a specific time (such as the third TTI), NACK feedback is performed on the received uplink data A; if the user equipment mistakenly detects the NACK as ACK, the user equipment will continue to send the second at a specific time (such as the fifth TTI). Upstream data B, the HPN of the upstream data B is also assumed to be 1. After the base station receives the uplink data B, because the HPNs corresponding to the uplink data A and the uplink data B are both 1 and the base station has NACK feedback on the uplink data A, the base station will mistake the uplink data B as a duplicate of the uplink data A. Therefore, HARQ combining is performed on the uplink data A and the uplink data B. Obviously, this combining process is inaccurate.

In the embodiment of the present invention, when the base station performs HARQ combining processing on uplink data, in order to ensure the accuracy of HARQ combining and reduce unnecessary data processing, the base station needs to know whether the uplink data sent by the user equipment is newly transmitted data or retransmitted data, Hence the introduction of NDI. In this embodiment of the present invention, whether the NDI is inverted may be used to indicate whether the data is newly transmitted or the data is retransmitted. For example, the user equipment transmits new transmission data A to the base station, and the HPN corresponding to the new transmission data A is 1, then the user equipment can set the NDI to zero; if the user equipment determines that the base station does not receive the uplink data A correctly, then the user equipment The uplink data will be retransmitted to the base station, and the NDI is still 0 at this time; if the user equipment determines that the base station has correctly received the uplink data A, the user equipment can transmit new uplink data through the HARQ process with HPN of 1, and the NDI can be set to 1 at this time , that is, through the inversion of NDI, it is possible to distinguish whether data is newly transmitted or retransmitted. Optionally, in this embodiment of the present invention, a fixed value can also be set for NDI to distinguish newly transmitted data and retransmitted data. For example, if NDI=0 is set to indicate new transmission data, NDI=1 indicates retransmission data, and the user equipment transmits new transmission data A to the base station, NDI will be set to 0 to indicate that the current transmission data is new transmission data, and if the user equipment If it is determined that the base station has not correctly received the uplink data A, the user equipment will retransmit the uplink data A to the base station, and at this time, the NDI will be set to 0 to indicate that the current transmission data is retransmission data.

In this embodiment of the present invention, when the base station performs HARQ combining of uplink data, in order to obtain the HARQ combining gain, the user equipment may use different RVs when retransmitting uplink data. In order to ensure the gain of HARQ combining, the user equipment may transmit the RV corresponding to the uplink data to the base station through the physical uplink channel.

S102, the user equipment preprocesses the uplink control information and the uplink data.

Specifically, the preprocessing of the uplink control information and the uplink data by the user equipment may include two cases: the first is independent preprocessing, that is, the uplink control information and the uplink data may be preprocessed according to their respective According to the performance target requirements, determine the resources occupied by each, and perform preprocessing respectively. For example, the uplink control information corresponds to the first preprocessing, and the uplink data corresponds to the second preprocessing; the second is joint preprocessing, that is, the The uplink control information and the uplink data determine jointly occupied resources, and then perform joint preprocessing. Optionally, the preprocessing (which may also be the first preprocessing or the second preprocessing) may include at least one of sequence modulation, channel coding and rate matching. Further optionally, the preprocessing (which may also be the first preprocessing or the second preprocessing) may include functions such as channel interleaving, constellation modulation, resource mapping, precoding, etc. in addition to sequence modulation, channel coding, and rate matching. Other processing methods in which the base station obtains corresponding information according to the received uplink data.

It should be noted that, in this embodiment of the present invention, when the preprocessing includes channel coding, the first preprocessing mode (ie, the independent preprocessing mode) can be understood as the user equipment separately processing the uplink control information and the uplink data. Perform channel coding, that is, the uplink control information and the uplink data are coded independently; the second preprocessing method (that is, the joint preprocessing method) can be understood as the user equipment performing the uplink control information and the uplink data. Joint coding, that is, the uplink control information and the uplink data are jointly coded.

S103, the user equipment transmits the preprocessed uplink control information and uplink data to the base station through a physical uplink channel.

Specifically, the user equipment transmits the preprocessed uplink control information and uplink data to the base station through a physical uplink channel. The physical uplink channel may be a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), or may be other channels that carry uplink data and/or uplink control information, such as a physical uplink control channel (Physical Uplink Control Channel, PUCCH) . After receiving the preprocessed uplink control information and the uplink data, the base station may perform inverse processing on the preprocessed uplink control information and uplink data (that is, the inverse process of preprocessing, which may include channel decoding, channel at least one of decoding and rate matching), for example, when the preprocessing method adopted by the user equipment is channel coding, the base station adopts the inverse processing method for channel decoding to recover uplink control information and uplink data.

It should be noted that, in this embodiment of the present invention, the user equipment may transmit the preprocessed uplink control information and the uplink data to the base station through the same physical uplink channel, or may also transmit the preprocessed uplink control information and the uplink data to the base station through the same physical uplink channel. The uplink control information and the uplink data are transmitted to the base station through different physical uplink channels, that is, the physical uplink channel in S103 can be understood as the same physical uplink channel or as different physical uplink channels.

In the embodiment of the present invention, the user equipment determines the uplink control information corresponding to the uplink data transmitted in the first time unit, then preprocesses the uplink control information and the uplink data, and stores the preprocessed uplink control information. The information and the uplink data are transmitted to the base station through the physical uplink channel, and the uplink data and uplink control information are transmitted to the base station through the user equipment, which realizes the transmission of UL grant free while ensuring the transmission efficiency of the uplink data and the adaptability of the uplink data transmission. Upstream transmission channel.

Please refer to FIG. 3 , which is a schematic flowchart of another information transmission method provided by an embodiment of the present invention. As shown in FIG. 3, the another information transmission method includes steps S201-S206.

S201, the user equipment determines uplink control information corresponding to the uplink data transmitted in the first time unit.

Specifically, for a partial explanation of this step S201, please refer to the specific explanation of step S101 in FIG. 2, and details are not repeated here.

Optionally, the first time unit is a time unit in a time set, and the time set includes at least two time units; the user equipment according to the uplink control information corresponding to the first time unit and the first preset A rule is set to determine uplink control information corresponding to other time units in the time set except the first time unit. Optionally, other time units in the time set other than the first time unit may include all time units in the time set except the first time unit.

Specifically, in this embodiment of the present invention, the uplink control information includes, in addition to the control information corresponding to the uplink data transmitted in the first time unit, the control information corresponding to the uplink data transmitted in other time units other than the first time unit. control information. The other time units and the first time unit may be continuous time units or discontinuous time units, which are not specifically limited in this embodiment of the present invention. Taking the first time unit and other time units as continuous time units as an example, as shown in FIG. 3 a , FIG. 3 a is a schematic diagram of a time set. The uplink control information corresponding to the first time unit may also indicate uplink control information corresponding to uplink data transmitted by other time units, such as the second time unit, the third time unit, and the fourth time unit, respectively, and the specific indication methods may include two Type: In the first indication mode, the uplink control information included in the first time unit directly includes the uplink control information corresponding to the uplink data respectively transmitted in other time units; in the second indication mode, the first time unit is only included in the first time unit. The uplink control information corresponding to the uplink data transmitted in the time unit is determined, and then the uplink control information corresponding to the uplink data transmitted in other time units is determined through the first preset rule. For example, using the second indication method, it is assumed that the uplink control information not included in the first time unit (using the HARQ process number as an example) indicates that the HARQ process number corresponding to the uplink data transmitted in the first time unit is HPN1, The user equipment may determine HARQ process numbers corresponding to uplink data transmitted in other time units in the time set according to the HPN1 and the first preset rule. For example, the HARQ process numbers corresponding to the uplink data transmitted in the second time unit, the third time unit and the fourth time unit are HPN2, HPN3 and HPN3 respectively, at this time, HPN2=(HPN1+1) or HPN2=(HPN1+1 )mod N, HPN3=(HPN1+2) or HPN3=(HPN1+2)mod N, HPN4=(HPN1+3) or HPN4=(HPN1+3)mod N, where N represents the maximum number of HPNs, mod is the remainder operator. With this implementation, control information overhead can be saved. For another example, if the first indication manner is adopted, the uplink control information included in the first time unit directly includes HPN1, HPN2, HPN3, and HPN4, among which. HPN1 , HPN2 , HPN3 , and HPN4 correspond to HARQ process numbers corresponding to the uplink data transmitted in the first time unit, the second time unit, the third time unit and the fourth time unit respectively. It should be noted that, in this embodiment of the present invention, the first preset rule may be preconfigured or predefined.

Optionally, the uplink data may be transmitted through at least two uplink codewords, and the uplink control information refers to control information corresponding to the first uplink codeword in the uplink data; An uplink codeword and a second preset rule are used to determine uplink control information corresponding to other uplink codewords other than the first uplink codeword in the uplink data. Specifically, the uplink data may be transmitted through at least two uplink codewords, the uplink control information may be control information corresponding to the first uplink codeword in the uplink data, and the user equipment may use the first uplink codeword according to the control information. and the second preset rule, determine the uplink control information corresponding to all the uplink codewords in the uplink data except the first uplink codeword. Still taking the uplink control information as HPN as an example, assuming that the uplink data may include four uplink codewords (uplink space division data transmission), namely the first uplink codeword to the fourth uplink codeword, the uplink control information HPN1 may be for For the first uplink codeword, the second to fourth uplink codewords correspond to HPN2, HPN3, and HPN4, respectively. The user equipment can determine HPN2=HPN1+1 or (HPN2=HPN1+1)modN, HPN3=HPN1+2 or (HPN3=HPN1+2)modN according to HPN1 corresponding to the first uplink codeword and the second preset rule , HPN4=HPN1+3 or (HPN4=HPN1+3) mod N. Among them, N represents the largest number of HPNs, and mod is the remainder operator.

S202, the user equipment obtains a first resource occupied by the uplink control information and a second resource occupied by the uplink data.

Specifically, in this embodiment of the present invention, the first resource may be the number of modulation symbols, the number of coded bits, or a sequence such as a demodulation reference signal (Demodulation Reference Signal, DMRS) sequence, or a constant amplitude zero correlation (Constant Amplitude Zero Auto-correlation) sequence. Correlation, CAZAC) sequence, or m sequence, or pseudo-random sequence, or other types of sequences; the second resource can be the number of modulation symbols, the number of coded bits, or a sequence such as a DMRS sequence, or a constant amplitude zero correlation CAZAC sequence, or m Sequences, or pseudorandom sequences, or other types of sequences. The user equipment obtains the first resource occupied by the uplink control information, that is, the user equipment calculates the number of modulation symbols and coded bits occupied by the uplink control information, or obtains the sequence used by the user equipment to transmit the uplink control information; the user equipment obtains the uplink control information. The second resource occupied by the data is the number of coded bits and the number of modulation symbols occupied by the user equipment to calculate the number of coded bits occupied by the uplink data, or the sequence used by the user equipment to obtain and transmit the uplink control information. The number of modulation symbols, the number of coded bits or the sequence used for transmitting uplink control information may be the same or different from the number of modulation symbols, number of coded bits or the sequence used for transmitting uplink data.

Optionally, the first resource is calculated and obtained according to the number of valid information bits corresponding to the uplink control information, the number of target information bits corresponding to the uplink data, and the target resource corresponding to the uplink data; wherein, the The number of target information bits corresponding to the uplink data is the number of valid information bits corresponding to the uplink data or the preset number of information bits corresponding to the uplink data, and the target resource corresponding to the uplink data is the capacity of the second physical uplink channel or preset resources corresponding to the uplink data.

Optionally, the first resource may also be a preset resource corresponding to the uplink control information.

Optionally, the first resource may also be obtained by calculation according to the number of valid information bits corresponding to the uplink control information and the modulation and coding scheme MCS. In this way, the MCS may be pre-configured or pre-defined, the MCS may be the same as or different from the MCS corresponding to the uplink data, and the number of valid information bits corresponding to the uplink control information is pre-configured , or predefined. For example, for the uplink control information, the pre-configuration adopts the QPSK modulation method, the coding rate is fixed, and the pre-configured number of valid information bits is Xbit, then the user equipment can calculate the coded bits by X/(fixed coding rate)/2 Number represents the first resource, and 2 is the modulation order corresponding to QPSK.

Specifically, the manner of determining the above-mentioned first resource may include the following:

First, the user equipment determines the first resource according to the number of valid information bits corresponding to the uplink control information, the number of valid information bits corresponding to the uplink data, and the capacity of the second physical uplink channel.

In this embodiment of the present invention, a physical uplink channel (first physical uplink channel) used for transmitting uplink control information after the first preprocessing and a physical uplink channel used for transmitting uplink data after the second preprocessing The uplink channel (the second physical uplink channel) may be the same or different. It should be noted that, in this embodiment of the present invention, when the first physical uplink channel is the same as the second physical uplink channel, that is, when uplink control information and uplink data are transmitted through the same physical uplink channel, the same physical uplink channel may It is represented by the second physical uplink channel, and can also be represented by the first physical uplink channel. Correspondingly, the capacity of the second physical uplink channel is equal to the capacity of the physical uplink channel including uplink control information and uplink data transmission; when the first physical uplink channel When different from the second physical uplink channel, the second physical uplink channel is a channel including uplink data transmission, and correspondingly, the capacity of the second physical uplink channel is equal to the capacity of the physical uplink channel including uplink data transmission. In this embodiment of the present invention, the physical uplink channel capacity may be represented by the number of modulation symbols or the number of coded bits.

It should be noted that, in this embodiment of the present invention, the user equipment may further determine the first resource according to the number of valid information bits corresponding to the uplink control information, the number of valid information bits corresponding to the uplink data, and the second resource. In this manner, the second resource may be preconfigured or pre-defined. When the first physical uplink channel is the same as the second physical uplink channel, the capacity of the second physical uplink channel includes the second resource. In this case, the capacity of the second physical uplink channel may be equal to or greater than the second resource. When the capacity of the two physical uplink channels is greater than the second resource, the second resource is the part of the resources used for transmitting uplink data in the second physical uplink channel, that is, the second resource is the capacity of the second physical uplink channel and the first resource. Poor resources. When the first physical uplink channel is different from the second physical uplink channel, the capacity of the second physical uplink channel is equal to the second resource. For example, when the second resource is represented by the number of modulation symbols, the number of modulation symbols occupied by the second resource is Q' _UL-SCH =Q', or Q' _UL-SCH =Q'-Q' _CI . where Q' is the capacity of the second physical uplink channel (represented by the number of modulation symbols), and the second physical uplink channel includes the transmission of uplink data (corresponding to the case where the first physical uplink channel is different from the second physical uplink channel), or Including transmission of uplink data and uplink control information (corresponding to the case where the first physical uplink channel is the same as the second physical uplink channel), Q' _CI is the number of modulation symbols occupied by the first resource.

The following takes "the user equipment determines the first resource according to the number of valid information bits corresponding to the uplink control information, the number of valid information bits corresponding to the uplink data, and the capacity of the second physical uplink channel" as an example to illustrate several specific ways of calculating the first resource. . It should be noted that when "the user equipment determines the first resource according to the number of valid information bits corresponding to the uplink control information, the number of valid information bits corresponding to the uplink data, and the second resource", the "second resource" in the following formula can be used. The capacity of the physical uplink channel" is replaced with "second resource".

The first resource occupied by the uplink control information (taking the number of modulation symbols as an example), the calculation formula of Q' _CI can be any of the following:

Represents a rounding up of · up, Q' represents the capacity of the second physical uplink channel represented by the number of modulation symbols, O _CI represents the number of valid information bits corresponding to the uplink control information, O _UL-SCH represents the valid information bits corresponding to the uplink data number. In formula (2) and formula (4), β _offset is a value semi-statically configured by high-layer signaling or a predefined value, wherein the high-layer signaling may be Radio Resource Control (Radio Resource Control, RRC) signaling, It may also be Medium Access Control (Medium Access Control, MAC) signaling. The β _offset can be used to adjust the channel coding rate of the uplink control information, so as to ensure the performance of the uplink control information and effectively utilize the transmission resources.

Optionally, the capacity of the second physical uplink channel (Physical Uplink Channel, PUCH) may be calculated by formula (5).

Taking the Long Term Evolution (Long Term Evolution, LTE) system as an example, assuming that a time unit is a subframe (Subframe), then

N _SRS represents the number of symbols used to transmit Sounding Reference Signal (SRS) in the current subframe. If there is SRS transmission in the current subframe, N _SRS is the number of time domain symbols used to transmit SRS. SRS transmission, then N _SRS =0.

Optionally, on the second physical uplink channel, the transmission of multiple uplink data or the transmission of uplink data of multiple user equipments may be implemented by means of orthogonal multiplexing. The same time resources and frequency resources can be used for transmission, and the base station can distinguish the multiple uplink data; or, multiplexing means that the uplink data transmission of multiple user equipments can be transmitted using the same time resources and frequency resources, and The base station can distinguish the uplink data transmission of the multiple user equipments. Multiplexing can be achieved through space division orthogonality, for example, multiple uplink data use different space division codes to realize space division multiplexing, or, multiplexing can also be realized by non-orthogonal multiplexing, which is not specifically described in this embodiment of the present invention. limited. In this case, the capacity of PUCH can also be calculated by formula (7):

For example, taking LTE as an example, it is assumed that the physical uplink channel occupies 1 subframe in time, and a subframe includes 2 time slots, each time slot includes 7 OFDM symbols, and the physical uplink channel occupies 12 subcarriers in frequency , and there are two symbols in a subframe for DMRS transmission, the subframe does not include SRS, then according to formula (6), it can be calculated that the physical uplink channel includes 12*(2*7-2)=144 resources Element (Resource Element, RE). If each RE can carry one modulation symbol, the physical uplink capacity is 144 modulation symbols.

Assuming that four different uplink data can be transmitted at the same time on the physical uplink channel by a certain orthogonal method, that is, V _SF =4, then according to formula (7), the capacity of the PUCH is 36 (144/4) modulation symbols, that is, when the physical uplink channel carries 4 different uplink data, the physical uplink channel capacity corresponding to each uplink data transmission is 36 modulation symbols. The above four different uplink data may be sent by one UE or multiple UEs.

Optionally, A/B/C/D may be related to the maximum number of OFDM symbols occupied by the uplink control information in the physical uplink channel. For example, when uplink control information and uplink data are transmitted through the same physical uplink channel, assuming that the uplink control information occupies at most 2 OFDM symbols in the second physical uplink channel, A/B/C/D can be expressed as

in

Indicates the number of subcarriers occupied by the second physical uplink channel in frequency. Taking the LTE system as an example, assuming that the physical uplink channel occupies N _PRB resource blocks (Resource Block, RB) in the frequency domain, and one RB includes 12 subcarriers, then

In this embodiment of the present invention, the number of valid information bits O _CI corresponding to the uplink control information may be pre-configured by the base station, or pre-defined, or may be determined by the user equipment according to its own hardware conditions, which is not specified in this embodiment of the present invention. limited. For example, if the number of uplink HARQ buffers supported by the user equipment is 8, the HPN can be represented by 3 bits, that is, O _CI =3. For another example, the uplink control information includes HPNs for multiple time units, each time unit corresponds to one HPN, and the HPN can be represented by 3 bits, then when there are HPNs of N time units (N≥1, and a natural number), it needs to be indicated. , in one possible way, _OCI = 3N.

In this embodiment of the present invention, the number of valid information bits corresponding to uplink data may be pre-configured or predefined, for example, pre-configured as 32 bytes (Bytes). The number of valid information bits corresponding to the uplink data can also vary within a preconfigured set of information bits. For example, the set of valid information bits corresponding to the uplink data of the user equipment configured by the base station includes K types of bits, specifically {bits 1 , the number of bits 2, ..., the number of bits K}, the user equipment can select the number of valid information bits corresponding to the uplink data in the set, and calculate the first resource according to the number of valid information bits corresponding to the selected uplink data. In this manner, the base station may determine the number of valid information bits corresponding to the uplink data and/or determine the first resource by means of blind detection. Optionally, the number of valid information bits corresponding to the uplink data can be calculated or obtained by looking up the second resource occupied by the uplink data and the MCS corresponding to the uplink data, and the second resource and/or the MCS can be pre-configured or pre-configured. Defined. Further optionally, a resource allocation (Resource Allocation, RA) corresponding to the second resource is pre-configured, and the RA here includes indicating a location in time and frequency of a physical uplink channel used for transmitting uplink data. The user equipment can obtain the second resource by calculation through the RA, and then can determine the number of valid information bits corresponding to the uplink data according to the second resource and the MCS. Optionally, in this embodiment of the present invention, the number of valid information bits corresponding to the uplink data may correspond to a transmission block size (Transmission Block Size, TBS). It should be noted that, when the user equipment determines the number of valid information bits corresponding to the uplink data through the second resource and the MCS, in the case that the time resource of the physical uplink channel is fixed, the second resource can also use the RB occupied by the physical uplink channel. number to represent. The fixed time resource here means that, taking the LTE system as an example, the physical uplink channel may occupy one subframe in time. Therefore, the user equipment can determine the number of valid information bits corresponding to the uplink data according to the number of RBs and the MCS corresponding to the uplink data. Make sure that the MCS index and the MCS are in one-to-one correspondence).

The capacity of the second physical uplink channel is the capacity of the physical uplink channel used to transmit the uplink control information and the uplink data, or the capacity of the physical uplink channel used to transmit the uplink data. The capacity of the second physical uplink channel may be represented by the number of modulation symbols, or by the number of coded bits. The capacity of the second physical uplink channel may be preconfigured or pre-defined by the base station, or it may be calculated according to the target information bits corresponding to the uplink data and the MCS, and the target information bits corresponding to the uplink data and/or the MCS may be It is preconfigured or predefined, and is not specifically limited in this embodiment of the present invention.

It should be noted that, in this embodiment of the present invention, the valid information bits of the uplink control information can be understood as the original information bits of the uplink control information, or the original information bits of the uplink control information. Redundancy Check, the number of information bits after CRC); correspondingly, the number of valid information bits of the uplink data can be understood as the number of original information bits of the uplink data, or the number of information bits after the original number of information bits of the uplink data is introduced into the CRC.

As an example, the first resource occupied by the line control information is the number of coded bits, there are two ways to determine the first resource. The number of modulation symbols Q′ _CI calculated by any one of them is multiplied by the modulation order Q _m corresponding to the uplink control information to obtain the first resource (represented by the number of coded bits); the second is the calculation formula (1)～ (4) Or the number of modulation symbols Q′ _CI in formulas (8) to (11) is replaced by the number of coded bits Q _CI , where Q _CI is the first resource represented by the number of coded bits, and the second physical uplink channel The capacity is also represented by the number of coded bits, that is, Q' is represented by Q, and Q is also the capacity of the second physical uplink channel (calculated by the number of coded bits). The corresponding relationship between the modulation order Q _m and different modulation modes is shown in Table 1.

Second, the user equipment determines the first resource according to the number of valid information bits corresponding to the uplink control information, the preset number of information bits corresponding to the uplink data, and the physical uplink channel capacity.

In this embodiment of the present invention, when a user transmits uplink data, the number of information bits corresponding to the uplink data may be various, and one of the number of information bits corresponding to the plurality of uplink data may be selected as the predetermined number according to the transmission requirements of the uplink service or other factors. Let the number of information bits O _ini . The base station indicates the preset information bits of the uplink data to the user equipment through the downlink control information.

The main difference between the second method and the first method is that one of the parameters used when calculating the first resource is replaced by "the number of valid information bits corresponding to the uplink data" with "the preset number of information bits corresponding to the uplink data", that is, O _UL-SCH is replaced by O _ini and other parameters can remain unchanged. Based on the transmission mode of UL grant free, when the user equipment transmits uplink data, there may be multiple valid information bits corresponding to the uplink data, so as to realize link adaptation and/or service adaptation. When the user equipment actually performs uplink data transmission, it can select the number of valid information bits corresponding to one of the uplink data according to the uplink service transmission requirements or other factors, and perform uplink data transmission, unlike the prior art (based on UL grants). transmission mode), the base station needs to indicate the number of valid information bits corresponding to the uplink data of the user equipment through downlink control information, such as TBS. Therefore, when the user equipment itself selects the number of valid information bits corresponding to the uplink data (ie, one of the transmission methods based on UL grant free), the base station cannot know the number of valid information bits corresponding to the uplink data selected by the user equipment. Although the base station may determine the number of valid information bits corresponding to the uplink data selected by the user equipment through blind detection, the computational complexity of the base station is relatively high. Correspondingly, due to the uncertainty of the number of valid information bits corresponding to the uplink data, resulting in The complexity of determining the first resource by the base station is relatively high. In the second manner, the base station can calculate the first resource according to the preset number of bits of information corresponding to the uplink data, and then can decode the uplink control information according to the first resource, which reduces the processing complexity of the base station for acquiring the first resource .

Optionally, the uplink control information may include indication information, where the indication information is used to indicate the target information bit number of the uplink data. In this way, the base station first calculates the first resource according to the preset number of bits of information corresponding to the uplink data, then decodes the uplink control information according to the first resource, and can determine the corresponding uplink data according to the indication information included in the uplink control information. Therefore, the decoding process of the uplink data of the base station can also be simplified, and the complexity of the base station processing can be reduced.

The following example illustrates the relationship between the preset number of information bits corresponding to the uplink data and the number of valid information bits corresponding to the uplink data. The preset number of information bits corresponding to the uplink data is only used to calculate the first resource. When the user equipment actually transmits the uplink data, the number of effective information bits transmitted may or may not be equal to the preset number of information bits. For example, the set of valid information bits corresponding to the uplink data is: {1000bit, 2000bit, 3000bit, 4000bit}, that is, when the user equipment performs uplink data transmission, at least one can be selected from this set as the valid information bit number corresponding to the uplink data (When the uplink data is transmitted through at least two uplink codewords, the user equipment may select one or multiple ones from the set as the number of valid information bits corresponding to the uplink data). In the second way, the preset number of information bits can be configured as 500 bits, or it can be one of the above sets but is pre-configured or predefined by the base station, such as 500 bits (the number of bits will not change within a period of time). The user equipment calculates and obtains the first resource according to the preset number of information bits, the number of valid information bits corresponding to the uplink control information, and the capacity of the second physical uplink channel. Further optionally, assuming that the preset information corresponding to the uplink data is 500 bits, and the number of valid information bits selected when the user equipment performs uplink data transmission is 2000 bits, the indication information included in the uplink control information can indicate that the uplink data corresponds to valid information. The number of messages is 2000 bits.

Third, the user equipment determines the first resource according to the number of valid information bits corresponding to the uplink control information, the number of valid information bits corresponding to the uplink data, and the preset resources corresponding to the uplink data.

The main difference between the third method and the first method is that one of the parameters used in calculating the first resource is replaced by "capacity of the second physical uplink channel" with "preset resources corresponding to uplink data", and the description of other parameters Reference may be made to the description of the first manner, which is not repeated here. In this embodiment of the present invention, if the first resource is represented by the number of modulation symbols, Q' is replaced by Q' _symb , and if it is represented by the number of coded bits, Q is replaced by Q _bit , where Q' _symb and Q _bit represent respectively The preset resource corresponding to the uplink data represented by the number of modulation symbols and the number of coded bits. When the user equipment transmits uplink data, the effective resource (which can be understood as the second resource) corresponding to the uplink data may vary with the number of information bits of the uplink data and different MCSs, so as to realize link adaptation. Therefore, in order to realize link adaptation for data transmission, the effective resource corresponding to the uplink data, that is, the second resource, can be selected by the user equipment, but the first resource will vary with the second resource corresponding to the selected uplink data. However, in this case, the base station can only determine the effective resources corresponding to uplink data transmission and determine the first resource by performing blind detection on the selected effective resources, which will increase the complexity of the base station operation. In order to solve the above problem, the embodiment of the present invention uses the user equipment to calculate the first resource according to the preset resource corresponding to the uplink data, and sends the uplink control information to the base station through the physical uplink channel according to the first resource, so that the base station can use the uplink data according to the uplink data. The corresponding preset resource calculates the first resource, and obtains uplink control information, which facilitates the operation of the base station. Optionally, the uplink control information may include indication information, where the indication information is used to indicate the physical uplink channel capacity used by the user equipment for transmitting uplink data and/or uplink control information. Optionally, the uplink control information may include indication information, where the indication information is used to indicate the second resource corresponding to the uplink data.

It should be noted that, in this embodiment of the present invention, the preset resource corresponding to the uplink data is only used to calculate the first resource. When the user equipment actually transmits the uplink data, the effective resource (for example, the second resource) corresponding to the uplink data may include The capacity of the second physical uplink channel for uplink data transmission or the capacity of the physical uplink channel including uplink data and uplink control information transmission (which can be represented by the first physical uplink channel or by the second physical uplink channel), which can be equal to the uplink data The corresponding preset resources may also not be equal to the preset resources corresponding to the uplink data.

Fourth, the user equipment determines the first resource according to the number of valid information bits corresponding to the uplink control information, the preset number of information bits corresponding to the uplink data, and the preset resources corresponding to the uplink data.

For this mode, please refer to the specific descriptions in the second and third modes, which will not be repeated here.

Fifth, the first resource is a preconfigured resource corresponding to the uplink control information or a predefined resource corresponding to the uplink control information.

Specifically, the first resource may be directly pre-configured by the base station or pre-defined. The pre-configuration may be implemented by high-layer signaling such as RRC signaling or MAC signaling, and the pre-definition includes setting a fixed resource value.

Sixth, the first resource may also be determined according to the preset information bit number of the uplink control information and the MCS corresponding to the uplink control information, wherein the preset information bit number of the uplink control information may be preconfigured or predefined, The MCS corresponding to the uplink control information may be preconfigured or predefined.

In this embodiment of the present invention, when the physical uplink channel for transmitting uplink control information is the same as the physical uplink channel for transmitting uplink data, the second resource may be the capacity corresponding to the physical uplink channel, or may be the capacity of the physical uplink channel after removing the first resource. In other words, when the physical uplink channel for transmitting uplink control information is the same as the physical uplink channel for transmitting uplink data, the second resource may be the capacity of the second physical uplink channel, or the capacity of the second physical uplink channel after removing the first resource. remaining capacity. When the physical uplink channel for transmitting uplink control information is different from the physical uplink channel for transmitting uplink data, the second resource may be the capacity of the physical uplink channel used for transmitting uplink data, or in other words, the second resource is the capacity of the second physical uplink channel.

It should be noted that, in this embodiment of the present invention, the physical uplink channel capacity (including the capacity of the first physical uplink channel or the capacity of the second physical uplink channel) may refer to removing uplink reference signals such as DMRS from the physical uplink channel capacity Or the sounding reference signal, such as the number of modulation symbols occupied by the SRS, the number of coded bits, or the remaining capacity after the number of resource elements RE. Or more generally, it may refer to the remaining capacity after removing the capacity occupied by important signals (for example, reference signals) and important uplink transmission channels from the physical uplink channel capacity. Optionally, if the uplink data includes uplink service data and uplink reference signals, the physical uplink channel capacity (including the capacity of the first physical uplink channel or the capacity of the second physical uplink channel) may not exclude uplink reference signals such as DMRS or SRS occupied. The number of modulation symbols, or the number of occupied REs.

In the embodiment of the present invention, whether it is the number of valid information bits corresponding to the uplink data or the number of valid information bits corresponding to the uplink control information, the preconfigured value may be one or more than one. In the embodiment of the present invention No specific limitation is made.

Optionally, the second resource is calculated and obtained according to the target information bit number corresponding to the uplink data and the MCS; or, the second resource is a preconfigured resource corresponding to the uplink data or the corresponding uplink data. predefined resources. Optionally, the uplink control information includes second indication information, and the second indication information indicates the second resource.

Optionally, the second resource can be determined in three ways: first, the second resource is obtained according to the target information bit number corresponding to the uplink data and the MCS calculation, wherein the target information bit number corresponding to the uplink data includes the uplink data. The corresponding number of valid information bits or the preset number of information bits corresponding to the uplink data, the preset number of information bits corresponding to the uplink data and the MCS can be pre-configured; second, the second resource can be pre-configured or pre-defined. ; The third type, the second resource is determined by the second indication information in the uplink control information.

In this embodiment of the present invention, the control information included in the uplink control information refers to information indicated by a combination of bits or information indicated by a single bit included in the uplink control information.

S203, the user equipment performs first preprocessing on the uplink control information according to the first resource.

Specifically, the user equipment performs first preprocessing on the uplink control information according to the first resource. The first preprocessing may include at least one of sequence modulation, channel coding, and rate matching, and may also include channel interleaving, constellation modulation, resource mapping, and precoding in addition to sequence modulation, channel coding, and rate matching. other processing methods for the base station to obtain corresponding information according to the received uplink data.

For the first preprocessing, taking channel coding as an example, assuming that the first resource is the number of modulation symbols Q′ _CI , the user equipment can calculate and obtain the uplink control information according to Q′ _CI and the modulation order Q _m corresponding to the uplink control information The number of coded bits Q _CI , specifically, Q _CI =Q′ _CI *Q _m . The user equipment performs channel coding on the uplink control information according to the calculated number of coded bits and the number of valid information bits corresponding to the uplink control information, and obtains a coded bit stream of the uplink control information.

For the first preprocessing, taking sequence modulation as an example, the user equipment may carry the number of valid information bits corresponding to the uplink control information on the reference sequence or reference signal according to the reference sequence or reference signal. Optionally, the user equipment may select a sequence corresponding to the combination according to the different combinations of the valid information bits of the uplink control information. For example, if the target number of information bits of the uplink control information is 3, there are 8 different combinations of the valid information bits. mode, which can correspond to 8 different sequences respectively, as shown in Table 2. Table 2 is the mapping relationship table between valid information bit combinations and sequences of uplink control information,

In this way, the user equipment obtains the first resource occupied by the uplink control information. An understanding is that the user equipment obtains the sequence corresponding to the valid information bit combination of the uplink control information. Table 2 is used as an example. That is, sequences corresponding to all possible combinations of valid information bits of the uplink control information, ie, sequence 1 to sequence 8, are obtained. Further, when the user equipment performs the first preprocessing on the uplink control information according to the first resource, it can be understood that the user equipment determines the sequence according to a combination of valid information bits of the uplink control information to be transmitted. For example, still taking Table 2 as an example, assuming that the valid information bit combination transmitted by the user equipment in a certain time unit is 011, the user equipment obtains the sequence 4 corresponding to the valid information bit combination of the uplink control information. At this time, the user equipment transmits the preprocessed uplink control information through the first physical uplink channel, which can be understood as the user equipment transmits sequence 4 through the first physical uplink channel. Optionally, the first physical uplink channel here may be represented by physical uplink resources transmitted by bearer sequence 4, such as REs or RBs. In addition, in this manner, the user equipment obtains the first resource occupied by the uplink control information, and another understanding is that the user equipment obtains a sequence corresponding to a combination of valid information bits of the uplink control information to be transmitted For example, still taking Table 2 as an example, assuming that the valid information bit combination transmitted by the user equipment in a certain time unit is 011, the user equipment obtains the sequence 4 corresponding to the valid information bit combination of the uplink control information. Further, when the user equipment performs first preprocessing on the uplink control information according to the first resource, it can be understood that the user equipment determines that the sequence to be sent is sequence 4. At this time, the user equipment transmits the preprocessed uplink control information through the first physical uplink channel. It can be understood that the user equipment transmits sequence 4 through the first physical uplink channel. It should be noted that, optionally, the first The physical uplink channel may be represented by physical uplink resources transmitted by bearer sequence 4, such as REs or RBs.

Optionally, assuming that the number of valid information bits of the uplink control information is M, there are 2 ^M different combinations, which can correspond to 2 ^M different sequences respectively.

Optionally, when the first preprocessing is sequence modulation, the first preprocessing may also be that the user equipment modulates the number of valid information bits corresponding to the uplink control information to obtain modulation symbols, and then carries the modulation symbols on the sequence. , the sequence can be preconfigured or predefined. In this manner, the user equipment obtains the first resource occupied by the uplink control information, which can be understood as the sequence used by the user equipment to obtain and transmit the uplink control information. Further optionally, the user equipment performs first preprocessing on the uplink control information according to the first resource, which can be understood as the user equipment modulates valid information bits corresponding to the uplink control information to obtain modulation symbols, Then, the modulation symbol is processed according to the aforementioned determined sequence, for example, the modulation symbol is multiplied by the determined sequence, or other methods are adopted. The user equipment transmits the first preprocessed uplink control information to the base station through the first physical uplink channel. It can be understood that the user equipment transmits the sequence bearing the modulation symbol information through the first physical uplink channel.

Table 2 Mapping relationship between valid information bit combinations and sequences of uplink control information

Optionally, for the number of valid information bits corresponding to the uplink control information to be transmitted, after channel coding, if the number of coded bits obtained after channel coding does not match the first resource, the number of coded bits after channel coding also needs to be calculated. Rate matching is performed so that the number of coded bits after channel coding matches the first resource. The mismatch here means that the number of coded bits obtained after channel coding is not equal to the number of coded bits represented by the first resource. When the first resource is the number of modulation symbols, the number of coded bits represented by the first resource can be understood as the multiplication of the first resource by the corresponding modulation order. For example, assuming that the number of information bits to be transmitted is 10, and channel coding with a coding rate of 1/3 is used, the number of coded bits obtained after channel coding is 30. At the same time, it is assumed that the first resource is the number of modulation symbols and is 20, corresponding to The modulation method is QPSK, that is, the corresponding modulation order is 2, then the number of coded bits corresponding to the first resource can be calculated to be 40. Obviously, the number of coded bits (30) after channel coding is the same as the number of coded bits represented by the first resource. (40) No match, in this case, rate matching needs to be performed on the number of coded bits after channel coding, so that it matches the number of coded bits represented by the first resource. This description is also applicable to the description of the number of valid information bits corresponding to the uplink data.

It should be noted that, in this embodiment of the present invention, optionally, rate matching also means that when the uplink control information is transmitted through the first physical uplink channel, the uplink control information only uses part of the resources in the first physical uplink channel to perform For transmission, other resources in the first physical uplink channel are used to transmit reference signals such as DMRS and SRS.

Optionally, the first preprocessing includes a process of adapting the number of valid information bits corresponding to the uplink control information to the first resource, and the adaptation may mean that the number of valid information bits corresponding to the uplink control information is obtained through the first preprocessing. The number of bits after the first preprocessing is equal to the number of encoded bits represented by the first resource.

In this embodiment of the present invention, whether it is for the first preprocessing, the second preprocessing, or the third preprocessing, when the preprocessing includes channel coding, the specific channel coding method may adopt Reed Miller RM (Reed-Muller RM). ) (32, O) (O represents the input encoder bit length), or double Reed-Muller RM (Reed-Muller) (32, O) code or tail biting convolution code TBCC (Tail biting convolution code), or extremely Polar code, or Turbo coding, or other channel coding, which is not specifically limited in this embodiment of the present invention.

Specifically, the uplink control information after the first preprocessing can also be processed by at least one of the following processing procedures (for example, scrambling, modulation, Discrete Fourier Transform (DFT), resource mapping, inverse discrete Fourier transform) Leaf change (Inverse Discrete Fourier Transform, IDFT, etc.), and then transmitted to the base station through the first physical uplink channel. Wherein, for the specific explanation of the first physical uplink channel and the uplink control information after the first preprocessing, please refer to the detailed description of S202-S203, which will not be repeated here. After receiving the first preprocessed uplink control information, the base station may perform inverse processing on the preprocessed uplink control information (that is, the inverse process of preprocessing may include at least one of channel decoding, channel decoding, and rate matching. type), for example, when the preprocessing method adopted by the user equipment is channel coding, the base station adopts the inverse processing method for channel decoding to restore the uplink control information.

Optionally, the user equipment performs channel coding and/or rate matching on the uplink control information according to the first resource, obtains a coded bit stream of the uplink control information, and converts the coded bits of the uplink control information. The stream is transmitted to the base station through the first physical uplink channel.

Optionally, steps S203 and S204 can also be replaced by the following methods:

"The user equipment performs channel coding and/or rate matching on the uplink control information according to the first resource to obtain the encoded bit stream of the uplink control information, and passes the encoded bit stream of the uplink control information through the first resource. A physical uplink channel is transmitted to the base station."

S205, the user equipment performs second preprocessing on the uplink data according to the second resource.

Specifically, the user equipment performs second preprocessing on the uplink control information according to the second resource. The second preprocessing may include at least one of sequence modulation, channel coding, and rate matching, and may also include channel interleaving, constellation modulation, resource mapping, and precoding in addition to sequence modulation, channel coding, and rate matching. other processing methods for the base station to obtain corresponding information according to the received uplink data.

For the second preprocessing, taking channel coding as an example, assuming that the second resource is the number of modulation symbols Q' _UL-SCH , the user equipment can, according to Q' _UL-SCH and the modulation order Q' _m corresponding to the uplink control information, can The number of coded bits Q _UL-SCH of the uplink control information is obtained by calculation, specifically, Q _UL-SCH =Q′ _UL-SCH *Q′ _m . The user equipment performs channel coding on the uplink control information according to the calculated number of encoded bits and the number of information bits of the uplink control information, and obtains the encoded bit stream of the uplink control information as:

When the second preprocessing corresponds to sequence modulation or rate matching, for the partial description and explanation of the second preprocessing, please refer to the detailed explanation of the first preprocessing in step S203, and only need to replace the first preprocessing with the first In the second preprocessing, the uplink control information is replaced with uplink data, which is not repeated here.

S206, the user equipment transmits the second preprocessed uplink data to the base station through the second physical uplink channel.

Specifically, the uplink control information after the second preprocessing can also be processed through at least one of the following processing procedures (for example, scrambling, modulation, Discrete Fourier Transform (DFT), resource mapping, inverse discrete Fourier transform) Leaf change (Inverse Discrete Fourier Transform, IDFT, etc.), and then transmitted to the base station through the second physical uplink channel. Wherein, for the specific explanation of the second physical uplink channel and the uplink control information after the second preprocessing, please refer to the detailed descriptions of S202-S203, which will not be repeated here. After receiving the second preprocessed uplink data, the base station may perform inverse processing on the second preprocessed uplink data (that is, the inverse process of preprocessing may include at least one of channel decoding, channel decoding, and rate matching. type), for example, when the preprocessing method adopted by the user equipment is channel coding, the base station adopts the inverse processing method to decode the channel to recover the uplink data.

Optionally, the user equipment performs channel coding and/or rate matching on the uplink data according to the second resource, obtains an encoded bit stream of the uplink data, and passes the encoded bit stream of the uplink data through the second resource.
