[0040] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0041] Please refer to Figure 1 , which shows a schematic diagram of a communication system provided by an embodiment of the present application. The communication system may include: a terminal device 10 and a network device.

[0042] The number of terminal devices 10 is usually multiple, and one or more terminal devices 10 may be distributed in a cell managed by each network device. The terminal device 10 may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile stations (MS), etc. For the convenience of description, in the embodiments of the present application, the above-mentioned devices are collectively referred to as terminal devices.

[0043] A network device is a device deployed in an access network to provide wireless communication functions for a terminal device 10. Network devices may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different wireless access technologies, the names of devices with network device functions may be different. For example, in a 5G NR system, it is called a gNodeB or a gNB. With the evolution of communication technology, the name "network device" may change. For the sake of convenience of description, in an embodiment of the present application, the above-mentioned devices that provide wireless communication functions for the terminal device 10 are collectively referred to as network devices. In one example, the network device and the terminal device 10 communicate with each other through some air interface technology, such as a Uu interface.

[0044] In one example, a network device may be deployed with multiple TRPs, for example, Figure 1 As shown, the network devices correspond to TRP1, TRP2...TRPn (TRP in Figure 1 The reference number is 20). The terminal device can use different transmission beams to send uplink channels (such as PUSCH) to different TRPs, and the network device can receive the uplink channels (such as PUSCH) sent by the terminal device through multiple TRPs. Exemplarily, due to the different relative orientations of different TRPs and terminal devices, the terminal device needs to use transmission beams with different beam directions to send uplink channels (such as PUSCH) to the TRP in the corresponding direction.

[0045] The "5G NR system" in the embodiments of the present disclosure may also be referred to as a 5G system or an NR system, but those skilled in the art may understand its meaning. The technical solution described in the embodiments of the present disclosure may be applicable to a 5G NR system or to a subsequent evolution system of the 5G NR system.

[0046] The technical solutions of the embodiments of the present disclosure can be applied to various communication systems, such as: Global System of Mobile Communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Advanced Long Term Evolution (LTE-A) system, New Radio (NR) system, NR system evolution system, LTE-based access to Unlicensed spectrum (LTE-U) system, NR-U system, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, Wireless Local Area Network (WLAN) system. Networks, WLAN), Wireless Fidelity (WiFi), next generation communication systems or other communication systems, etc.

[0047] 3GPP introduced collaborative transmission technology based on multiple TRPs in the 5G NR system. The application of multiple TRPs / Panels (antenna panels) in network equipment is mainly to improve the coverage at the edge of the cell, provide a more balanced service quality in the service area, and transmit data collaboratively between multiple TRPs / Panels in different ways. From the perspective of network morphology, network deployment with a large number of distributed access points plus centralized baseband processing will be more conducive to providing a balanced user experience rate and significantly reduce the latency and signaling overhead caused by handover. By utilizing the collaboration between multiple TRPs / Panels and transmitting / receiving channels from multiple beams in multiple directions, various occlusion / blocking effects can be better overcome, ensuring the robustness of link connections, and it is suitable for URLLC (Ultra Reliable Low Latency Communication) services to improve transmission quality and meet reliability requirements.

[0048] During the R16 (Release 16) research phase, the application of collaborative transmission technology based on multiple TRPs mainly enhanced the transmission of PDSCH (Physical Downlink Shared Channel). Since data transmission includes scheduling feedback of uplink and downlink channels, in the study of URLLC, only enhancing the downlink data channel cannot guarantee service performance. Therefore, the discussion in R17 continued to enhance PDCCH (Physical Downlink Control Channel), PUCCH (Physical Uplink Control Channel), and Physical Uplink Shared Channel (PUSCH).

[0049] The uplink transmission schemes of PUSCH include: 1. Codebook-based uplink transmission; 2. Non-codebook-based data transmission. The two uplink transmission schemes are described below respectively.

[0050] 1. Codebook-based uplink transmission.

[0051] In the NR system, the access network device can configure at most one SRS resource set for the terminal for codebook-based uplink transmission, which is achieved by configuring an SRS resource set as a "codebook".

[0052] When the access network device schedules PUSCH through downlink control information (DCI) format 0_1, and the access network device configures two SRS resources for uplink transmission based on the codebook for the terminal, the terminal determines the precoding and the number of transmission streams of PUSCH according to the SRS resource indication information (SRS Resource Indicator, SRI) and the transmitted precoding matrix indication information (Transmitted Precoding Matrix Indicator, TPMI) / transmitted Rank Indicator, TRI, and maps the data stream to the port of the SRS resource indicated by the SRI through the determined precoding for transmission.

[0053] When the base station configures multiple SRS resources for codebook-based uplink transmission for the terminal and there is an SRI indication field, an SRI indication field is used to indicate which SRS resource among the multiple SRS resources for codebook-based uplink transmission configured for the terminal by the base station. When the base station schedules PUSCH through DCI format 0_1 ​​and the base station only configures one SRS resource for codebook-based uplink transmission for the terminal, there is no SRI indication.

[0054] The data of the terminal in uplink transmission needs to be precoded using the precoding matrix indication information (Precoding Matrix Indicator, PMI) and stream number indication information (Rank Indicator, RI) specified by the network side, and the precoded data is mapped to the corresponding antenna port according to the spatial filter (SpatialRelationInfo) corresponding to the SRS resource indicated by SRI.

[0055] Schematically, Table 1 shows the indication method of SRI corresponding to multiple SRS resources.

[0056] Table 1

[0057] Bit field mapped to index <![CDATA[SRI(s),N SRS =2]]> 0 0 1 1

[0058] According to Table 1, when the designated bit of DCI takes the value of 0, the SRI field corresponding to the bit is used to indicate the use of the 0th SRS resource; correspondingly, when the designated bit of DCI takes the value of 1, the SRI field corresponding to the bit is used to indicate the use of the 1st SRS resource.

[0059] Table 2 shows the signaling indication methods of TPMI and RI for single-layer transmission with 4 antenna ports as an example, targeting different UE capabilities, where UE capabilities include full correlation, partial correlation and irrelevant.

[0060] Table 2

[0061]

[0062] The codebook subset corresponding to the uncorrelated type is all the precoded codewords in the codebook that correspond to any data stream transmitted through only one antenna port. The codebook subset corresponding to the partially correlated type is all the codewords in the codebook that meet the following conditions: any data stream is transmitted through one antenna port, or the first and third ports, or the second and fourth ports. The codebook subset corresponding to the fully correlated type is all the codewords in the codebook.

[0063] Indicatively, according to Table 2, taking the full correlation type as an example, when the bit value is 0, the corresponding expression transmission layer number is 1, and the corresponding TPMI information corresponding to the TPMI domain indicates that the 0th precoding matrix in the codebook is used for precoding.

[0064] Table 3 shows the form of the codebook.

[0065] Table 3

[0066]

[0067] 2. Non-codebook based uplink transmission.

[0068] In the NR system, the base station can configure at most one SRS resource set for the terminal for non-codebook based uplink transmission, which is achieved by configuring one SRS resource set as "noncodebook".

[0069] For non-codebook-based uplink transmission, the terminal sends a maximum number of SRS resources that can be transmitted simultaneously to the base station. The resource set can be configured with up to 4 SRS resources, and each SRS resource contains 1 SRS port. The base station can indicate to the terminal through SRI that one or more SRS resources are used for PUSCH precoding determination. The number of SRS resources corresponding to SRI is the number of streams transmitted by PUSCH. When the base station configures only one SRS resource for the terminal for non-codebook uplink transmission, DCIformat 0_1 ​​does not include SRI, and the terminal determines the precoding of PUSCH based on the configured SRS resources.

[0070] In the current R17 discussion, for multi-TRP enhancement, codebook-based PUSCH transmission introduces two TPMI domains and two SRI domains. When two SRS resource sets are configured, PUSCH uses the first SRI domain to indicate that the corresponding SRS resources are used for transmission in the first TRP direction. The specific precoding and number of layers used for transmission are indicated by the first TPMI domain. PUSCH uses the second SRI domain to indicate that the corresponding SRS resources are used for transmission in the second TRP direction. The specific precoding and number of layers used for transmission are indicated by the second TPMI domain.

[0071] However, this solution results in a large overhead of DCI signaling, which reduces the DCI demodulation performance in the multi-TRP scenario.

[0072] The present disclosure provides an uplink transmission method, please refer to Figure 2 , which shows a flowchart of an uplink transmission method provided by an exemplary embodiment of the present disclosure, taking the method applied in a terminal as an example, Figure 2 As shown, the method includes:

[0073] Step 201: receiving configuration signaling, where the configuration signaling includes a first indication field, and the first indication field is used to indicate TPMI indication information when a terminal sends a codebook-based uplink transmission of a PUSCH.

[0074] In some embodiments, the field used to indicate the TPMI indication field in the configuration signaling includes only the first indication field. In some embodiments, the configuration signaling includes any one of physical layer signaling, radio resource control (RRC) signaling, and media access control element (MAC CE). In this embodiment, the configuration signaling is implemented as RRC signaling as an example for description.

[0075] Optionally, the first indication field is used to indicate TPMI indication information when the terminal sends a codebook-based uplink transmission of PUSCH to one or at least two TRPs. In some embodiments, the TPMI indication information is used to indicate that the terminal configures a second TPMI domain during codebook-based uplink transmission; or, the TPMI indication information is used to indicate that the terminal does not have the ability to configure a second TPMI domain during codebook-based uplink transmission.

[0076] In some embodiments, the configuration signaling is directly configured by the network device to the terminal; that is, regardless of whether the terminal has the UE capability to support the second TPMI domain, the network device can send configuration information to the terminal to configure the terminal to determine the sending precoding through the configured TPMI domain during codebook-based transmission.

[0077] Alternatively, after receiving the UE capability reported by the terminal device, the network device sends the configuration signaling to the terminal according to the UE capability. That is, the terminal first sends UE capability related information to the network device, and the UE capability related information is used to indicate whether the terminal supports the ability to configure the second TPMI indication field in the DCI when supporting the collaborative transmission of PUSCH with at least two TRPs, so that the network device sends the configuration signaling to the terminal according to the UE capability related information.

[0078] Step 202: Determine the precoding used when sending the PUSCH based on the TPMI indication information.

[0079] In some embodiments, the precoding used when sending PUSCH in one TRP direction is determined based on the TPMI indication information; or, the precoding used when sending PUSCH in at least two TRP directions is determined based on the TPMI indication information.

[0080] In the embodiment of the present disclosure, when the TPMI indication information is used to instruct the terminal to indicate the precoding matrix through the TPMI field, the precoding of the PUSCH is determined through the TPMI information in the TPMI field.

[0081] In some embodiments, after determining the precoding used when sending the PUSCH, the transmit beam of the PUSCH is determined according to the precoding for transmission.

[0082] In some embodiments, the uplink transmission scheme of PUSCH includes codebook-based uplink transmission and non-codebook uplink transmission. For PUSCH transmission for different TRPs, the direction information can be indicated by the SRI field in the DCI signaling, and the specific precoding is indicated using the TPMI field.

[0083] Currently, the time division multiplexing (TDM) repetition modes of PUSCH mainly include PUSCH repetition type A and PUSCH repetition type B. Repetition type A and repetition type B are described below respectively.

[0084] Repetition type A: RRC signaling is used to configure repeated transmission between time slots, and the same transport block (Transport Block, TB) is repeatedly transmitted on multiple transmission opportunities (nominalrepetition). The transmission opportunity refers to the continuous time domain resources for transmitting PUSCH in the time domain. In transmission type A, one transmission opportunity is in one time slot, and different transmission opportunities are in different time slots. Transmission type A is mainly used at the edge of the cell, and therefore limits the number of transmission layers to one-sided transmission. A PUSCH is transmitted in K consecutive time slots, i.e., K transmission opportunities. Transmission starts at the Sth symbol in the starting time slot. Each transmission opportunity lasts for L symbols, and S+L does not exceed the slot boundary (slotboundary). For an illustration, please refer to Figure 3 , which shows a schematic diagram of repetition type A of PUSCH, such as Figure 3 As shown, during the transmission process of the PUSCH channel 310, the terminal device performs the first repeated transmission from the 4th symbol to the 7th symbol in the first time slot, and performs the second repeated transmission from the 4th symbol to the 7th symbol in the second time slot, wherein one time slot includes 14 symbols, namely the 0th symbol to the 13th symbol.

[0085] Repetition type B: Transmission type B can realize back-to-back continuous transmission for the same TB, and can cross time slot boundaries. This transmission type has no limit on the number of transmission layers and can support data transmission of uplink layers 1-4. In the time domain, a PUSCH starts transmission at the Sth symbol in the starting time slot, and sends K transmission opportunities continuously. Each transmission opportunity occupies L symbols continuously (back-to-back), and transmission S+L can cross time slot boundaries. That is, in transmission type B, one time slot can include one or more transmission opportunities.

[0086] Indicative, Figure 4 FIG. 4 is a schematic diagram showing a repetition type B of a PUSCH. Figure 4 As shown, a PUSCH starts transmission at the 4th symbol in the starting time slot, sends 4 transmission opportunities continuously, and each transmission opportunity occupies 4 symbols continuously. Figure 4 The transmission of a PUSCH channel 410 is shown.

[0087] For PUSCH based on multi-TRP transmission, the terminal further obtains spatial diversity gain and improves transmission reliability by jointly sending a unified TB of PUSCH to different TRPs. For different transmission opportunities, the transmission corresponding to different beam directions can be mapped. Specifically, the repeated transmission of multiple TBs can be mapped to K specific transmission opportunities through the following multiple possible mapping rules. Therefore, the transmission opportunities corresponding to beams sent to different TRPs are divided into two groups. Taking K=8 as an example, alternating mapping (cyclic mapping), eg: 12121212; sequential mapping (Sequential mapping), eg: 11221122; half-half mapping (Half-half mapping), eg: 11112222.

[0088] Optionally, the terminal determines a PUSCH transmission scheme according to the configured TPMI indication information. The PUSCH transmission scheme includes at least one of the following situations:

[0089] First, the precoding indicated by the TPMI information in the TPMI field is applied to all transmission opportunities of the PUSCH.

[0090] Optionally, regardless of whether the current transmission configuration is multi-TRP transmission, only the precoding corresponding to the TPMI information indicated by the network in the first TPMI field is used for PUSCH transmission, and is applied to all transmission opportunities of PUSCH. That is, for PUSCH transmission in one TRP direction or PUSCH transmission in multiple TRP directions, only the precoding corresponding to the TPMI information indicated by the network in the first TPMI field is used.

[0091] Second, the precoding indicated by the TPMI information in the TPMI field is applied to the first transmission opportunity of the PUSCH.

[0092] That is, the TPMI information indicated by the network in the first TPMI field is used, and the TPMI information is only used for the first transmission opportunity, and subsequent transmission opportunities may use the same or different precoding.

[0093] Optionally, the precoding preconfigured by the network is applied to the nth transmission opportunity of the PUSCH, where n>1, and n is an integer, and the same or different precodings are applied to different transmission opportunities.

[0094] Alternatively, the predefined precoding is applied to the nth transmission occasion of the PUSCH, where n>1, and n is an integer, and the same or different precodings are applied to different transmission occasions.

[0095] In some embodiments, a set of precodings associated with the TPMI information in the TPMI field and determined by the terminal for use according to certain known information is applied to the transmission timing of the PUSCH after the first transmission timing, and the same or different precodings are applied to different transmission timings.

[0096] Third, the precoding indicated by the TPMI information in the TPMI domain is applied to the first transmission opportunity in the transmission opportunity group corresponding to the sending of PUSCH in each TRP direction.

[0097] In some embodiments, transmission opportunities other than the first transmission opportunity use the same or different precoding.

[0098] In some embodiments, when the SRS resource set is configured as at least one and there is at least one SRI indication field, the precoding indicated by the TPMI field is applied to send PUSCH in the beam direction corresponding to the SRS resource indicated in each SRI field; or, when the SRS resource set is configured as at least one but there is no corresponding SRI indication field, the precoding indicated by the TPMI field is applied to send PUSCH in the beam direction corresponding to the resource of the SRS contained in each SRS resource set.

[0099] In summary, the uplink transmission method provided by the embodiment of the present disclosure considers a configurable uplink transmission scheme in the transmission of uplink PUSCH, supports the use of macro diversity to reduce the DCI signaling overhead caused by TPMI, and enhances the robustness of uplink repeated transmission.

[0100] Figure 5 FIG. 1 is a flow chart of an uplink transmission method provided by an exemplary embodiment of the present disclosure, and takes the method applied to a network device as an example for explanation. Figure 5 As shown, the method includes:

[0101] Step 501: Send configuration signaling to a terminal, where the configuration signaling includes a first indication field, and the first indication field is used to indicate TPMI indication information when the terminal sends a codebook-based uplink transmission of a PUSCH.

[0102] In some embodiments, the configuration signaling is directly configured by the network device to the terminal; that is, regardless of whether the terminal has the UE capability to support the second TPMI domain, the network device can send configuration information to the terminal to configure the terminal to determine the sending precoding through the configured TPMI domain during codebook-based transmission.

[0103] Alternatively, after receiving the UE capabilities reported by the terminal device, the network device sends the configuration signaling to the terminal according to the UE capabilities. That is, the network device receives the UE capability related information sent by the terminal, and the UE capability related information is used to indicate whether the terminal supports the ability to configure the second TPMI indication field in the DCI when supporting the collaborative transmission of PUSCH in at least two TRP directions.

[0104] Step 502: determine the precoding used when receiving the PUSCH based on the TPMI indication information.

[0105] In some embodiments, the TPMI indication information is configured to be applied to the precoding used when receiving PUSCH in one TRP direction, or the TPMI indication information is configured to be applied to the precoding used when receiving PUSCH in at least two TRP directions.

[0106] Optionally, the precoding indicated by the TPMI information in the TPMI field is configured to be applied to all transmission opportunities of the PUSCH.

[0107] Alternatively, the precoding indicated by the TPMI information in the TPMI field is configured to be applied to the first transmission opportunity of the PUSCH, and the preconfigured precoding or predefined precoding is used for the other transmission opportunities except the first transmission opportunity. That is, in the case of preconfiguration: configuration information is sent to the terminal, and the configuration information is used to configure the terminal with the precoding applied to the nth transmission opportunity of the PUSCH, n>1, and n is an integer, and the same or different precodings are applied to different transmission opportunities; in the case of predefinition: the precoding applied to the nth transmission opportunity of the PUCH is predefined, n>1, and n is an integer, and the same or different precodings are applied to different transmission opportunities.

[0108] Alternatively, the precoding indicated by the TPMI information in the TPMI domain is configured to be applied to the first transmission opportunity in the transmission opportunity group corresponding to the PUSCH received in each TRP direction, and the other transmission opportunities other than the first transmission opportunity use the same or different precoding.

[0109] In summary, the uplink transmission method provided by the embodiment of the present disclosure considers a configurable uplink transmission scheme in the transmission of uplink PUSCH, supports the use of macro diversity to reduce the DCI signaling overhead caused by TPMI, and enhances the robustness of uplink repeated transmission.

[0110] Figure 6 A flowchart of an uplink transmission method provided by an exemplary embodiment of the present disclosure is provided, and the method is applied in a communication system as an example for explanation. Figure 6 As shown, the method includes:

[0111] Step 601: The terminal sends UE capability related information to a network device.

[0112] UE capability related information is used to indicate whether the terminal supports the ability to configure the second TPMI indication field in the DCI when supporting the collaborative transmission of PUSCH with at least two TRPs.

[0113] Step 602: The network device sends a configuration signaling to the terminal. The configuration signaling includes a first indication field. The first indication field is used to indicate TPMI indication information when the terminal sends a codebook-based uplink transmission of a PUSCH.

[0114] In some embodiments, the configuration signaling includes only the first indication field.

[0115] In some embodiments, the configuration signaling includes any one of physical layer signaling, RRC signaling, and MAC CE. In this embodiment, the configuration signaling is implemented as RRC signaling as an example for description.

[0116] Optionally, the first indication field is used to indicate TPMI indication information when the terminal sends a codebook-based uplink transmission of PUSCH to one or at least two TRPs. In some embodiments, the TPMI indication information is used to indicate that the terminal does not have the ability to configure a second TPMI field during codebook-based uplink transmission.

[0117] Step 603: The terminal determines the precoding used when sending the PUSCH based on the TPMI indication information.

[0118] In some embodiments, the precoding used when sending PUSCH in one TRP direction is determined based on the TPMI indication information; or, the precoding used when sending PUSCH in at least two TRP directions is determined based on the TPMI indication information.

[0119] In the embodiment of the present disclosure, when the TPMI indication information is used to instruct the terminal to indicate the precoding matrix through the TPMI field, the precoding of the PUSCH is determined through the TPMI information in the TPMI field.

[0120] In some embodiments, the uplink transmission scheme of PUSCH includes codebook-based uplink transmission and non-codebook uplink transmission. For PUSCH transmission for different TRPs, the direction information can be indicated by the SRI field in the DCI signaling, and the specific precoding is indicated using the TPMI field.

[0121] Step 604: The terminal transmits PUSCH according to precoding.

[0122] In some embodiments, after determining the precoding used when sending the PUSCH, a transmit beam of the PUSCH is determined based on the precoding for transmission.

[0123] Step 605: The network device determines the precoding used when receiving the PUSCH based on the TPMI indication information.
