It is to be understood that data so used are interchangeable where appropriate, such that the embodiments of the present application may be performed in an order other than that shown or described herein, and that the objects distinguished by "first" and "second" are generally of the same type and do not limit the number of objects, e.g., the first object may be one or more. Note that "and / or" in the specification and claims represents at least one of the objects connected, and the character " / " generally represents an "or" relationship between the related objects.

[0018] It should be noted that the techniques described in the embodiments of the present application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be applied to other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in the embodiments of the present application are always used interchangeably, and the techniques described may be used in the above-mentioned systems and radio technologies, or in other systems and radio technologies. Although the following description describes a New Radio (NR) system for illustrative purposes and uses NR terminology in most of the description below, these techniques may be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems.

[0019] FIG. 1 is a block diagram of a wireless communication system to which the embodiment of the present application can be applied. The wireless communication system includes a terminal 11 and a network side device 12. Here, the terminal 11 may be called a terminal device or a user terminal (User Equipment, UE), and the terminal 11 may be a terminal side device such as a mobile phone, a tablet personal computer, a laptop computer (or called a notebook computer), a personal digital assistant (PDA), a palmtop computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID), a wearable device (Wearable Device) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE), etc., and the wearable device includes a bracelet, an earphone, glasses, etc. It should be noted that the specific type of the terminal 11 in the embodiment of the present application is not limited. The network side equipment 12 may be a base station or a core network, where the base station may be called a Node B, an evolved Node B, an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a transmitting receiving point (TRP), or any other suitable term in the art, and as long as the same technical effect is achieved, the base station is not limited to a specific technical term, and it should be explained that in the embodiments of this application, only a base station in an NR system is taken as an example, but the specific type of the base station is not limited.

[0020] In a multi-transmission point / multi-antenna panel (multi-TRP / multi-panel) scenario in a communication system, the reliability of transmission and the throughput performance can be increased. In a downlink link, a UE can receive the same or different data from multiple TRPs. In an uplink link, a UE can transmit different data to multiple TRPs. Here, multiple CORESETs that the network side can configure for a UE are associated with different RRC parameters CORESETPoolIndex and correspond to different TRPs. Each TRP schedules its uplink transmission PUSCH by transmitting its respective DCI, that is, in a multi-TRP scenario, a multi-DCI is adopted to schedule PUSCH transmission. The communication system further reinforces the PUSCH in the MTRP, and the UE can transmit the same data to two TRPs.

[0021] In the MTRP scenario, one transport block (TB) of the PUSCH can be repeatedly transmitted to multiple TRPs. The repeated transmission of the PUSCH adopts multiple sets of parameters including spatial relationships, precoding matrices, power control, etc., each for a different TRP. The conventional technology supports the repeated transmission of the PUSCH to adopt up to two sets of spatial relationships, and the corresponding TPMI also needs two sets of parameters. In the MTRP scenario, up to two SRS resource sets for codebook or non-codebook transmission can be configured. The SRI field and TPMI field of the corresponding DCI that schedules the PUSCH need to extend the original bit number by one to indicate the corresponding two sets of parameters. 0100

[0022] In uplink full power transmission, up to four SRS resources can be configured in each SRS resource set, and multiple TPMIs can be introduced to indicate full power transmission codebooks. However, the bit overhead of the SRI field and the TPMI field itself is very large. If the conventional method is continued to be adopted and the SRI field and the TPMI field are directly doubled, the overhead of the DCI will be very large. And the MTRP scenario may support PUSCH repetition transmission to more TRPs, in which case the conventional method will not be applicable.

[0023] In order to overcome the above drawbacks, this application proposes a PUSCH transmission method and apparatus.

[0024] Hereinafter, the PUSCH transmission method according to the embodiments of the present application will be described in detail with reference to several embodiments and application scenarios thereof in conjunction with the drawings.

[0025] FIG. 2 is a flowchart of a PUSCH transmission method according to an embodiment of the present application. As shown in FIG. 2, the method includes the following steps:

[0026] Step 200: the terminal determines, according to the received first indication information, a target transmission resource allocation indicated by the first indication information in at least one transmission resource allocation; Step 210. Transmitting a PUSCH according to the target transmission resource allocation; Here, the first instruction information is Sounding reference signal (SRS) resource indication information; Precoding matrix indication TPMI indication information; a phase tracking reference signal (PTRS) and a transmission port indication; The at least one transmission resource allocation includes: The network side is instructed in advance; being predefined by a protocol; Being pre-positioned; Indicated by the RRC layer; and / or is indicated by the MAC layer.

[0027] Alternatively, the target transmission resource allocation may be a resource allocation for transmitting a PUSCH of the terminal.

[0028] Alternatively, for codebook-based PUSCH transmission, the network side may configure an SRS resource set obtained for the UE based on uplink transmission CSI, and each SRS resource set may include two SRS resources, where the number of ports included in the two SRS resources may be the same, that is, both may be 1, 2, or 4 ports. The two SRS resources are configured to correspond to different beams.

[0029] The network side obtains uplink channel information by measuring SRS on different SRS resources, selects parameters such as spatial relationship, precoding matrix, power control, MCS, etc. of PUSCH transmission for the UE based on the uplink channel information, and indicates these transmission parameters for the UE through the SRI field / TPMI field / TPC field / MCS field in DCI format 0_1 / 0_2 for scheduling PUSCH. The spatial relationship and port that are the same as the SRS resource indicated by the SRI field can be adopted when transmitting PUSCH.

[0030] Alternatively, for non-codebook transmission, four SRS resources may be configured in each resource set SRS resource set for non-codebook transmission, and the number of ports of all SRS resources may be 1. In each SRS resource set, an associated CSI-RS for the UE to measure a downlink channel may be configured, and based on channel reciprocity, the UE may assume that the measured downlink channel is an uplink channel, and may calculate a precoding matrix for uplink transmission based on the channel information, and may adopt the precoding matrix to precode the SRS and transmit it to the network side, and the network side may determine the precoding used by the UE to transmit the PUSCH based on the measured precoded SRS, and indicate it by the SRI field of the DCI for scheduling the PUSCH. That is, the precoding matrix to be adopted for the PUSCH transmission may be indicated by indicating a subset of all precoded SRS resources transmitted by the UE by the SRI field.

[0031] Alternatively, SRS resource indication information may be employed to indicate an SRS resource, and the terminal may employ a spatial relationship and a port that are the same as the SRS resource to transmit the PUSCH.

[0032] Alternatively, the indication TPMI indication information may be employed to indicate a precoding matrix, and the terminal may employ the precoding matrix to precode the SRS.

[0033] Alternatively, PTRS transmission port indication information may be employed to indicate the PTRS transmission port, and the PTRS-DMRS association field may indicate in which layer the PTRS is uploaded, and the terminal may determine in which layer the PTRS is uploaded.

[0034] Alternatively, one layer may correspond to one DM-RS port.

[0035] Alternatively, the TPMI indication information, the PTRS transmission port indication information, and the TPMI indication information may indicate corresponding information in resource allocation for transmitting the PUSCH by any one or any combination of the TPMI indication information.

[0036] Alternatively, after determining the target transmission resource allocation, that is, after determining the resource allocation for transmitting the PUSCH, the PUSCH may be transmitted based on the resource allocation for transmitting the PUSCH.

[0037] Optionally, the terminal may determine, according to first indication information in the DCI, a target transmission resource allocation indicated by the first indication information; Here, the first indication information is used to indicate a target transmission resource allocation among at least one transmission resource allocation.

[0038] Optionally, the network side may include first indication information in DCI and send it to the terminal, and the terminal may obtain the first indication information therein after receiving the DCI, and determine a target transmission resource allocation indicated by the first indication information; As can be understood, the first indication information only includes indication content, and the specific transmission resource configuration content may be separately sent to the terminal by the network side, or may be pre-defined or pre-configured by a protocol, or may be indicated by the RRC layer, or may be indicated by the MAC layer.

[0039] Optionally, in an MTRP scenario, the PUSCH transmission may adopt at least one set of spatial relationships, at least one set of TPMI.

[0040] Alternatively, multiple sets of spatial relationships, multiple sets of TPMI parameters may be proposed, i.e., one or multiple transmission resource allocations may be proposed; alternatively, corresponding resource indication may be performed by multiple indication methods, and it is possible to support transmitting PUSCH to multiple TRPs while ensuring low overhead of DCI for scheduling PUSCH repeated transmission.

[0041] Optionally, when determining a target transmission resource allocation indicated by the first indication information, the terminal may determine the target transmission resource allocation indicated by the first indication information in one or more transmission resource allocations based on the first indication information.

[0042] The embodiments of the present application indicate at least one transmission resource configuration, i.e., multiple sets of transmission parameters, for UE PUSCH repeated transmission, while ensuring that DCI overhead is not increased excessively.

[0043] In an embodiment of the present application, a target transmission resource allocation for transmitting a PUSCH is instructed to a terminal by at least one of SRS resource indication information, TPMI indication information, and PTRS transmission port indication information, thereby reducing the bit overhead of the SRI field and / or the TPMI field when allocating PUSCH transmission resources.

[0044] Optionally, the SRS resource indication information includes an SRI field code point value; The terminal determines, based on first indication information in the DCI, a target transmission resource allocation indicated by the first indication information, determining target SRI field code point information among at least one SRI field code point information according to the SRI field code point value in the DCI; and determining, by the terminal, target SRI field code point information among at least one SRI field code point information, The network side is instructed in advance; being predefined by a protocol; Being pre-positioned; Indicated by the RRC layer; and / or being indicated by a MAC layer; Here, the SRI field code point information is associated with at least one SRS resource, or the SRI field code point information is associated with at least one SRS resource group.

[0045] Alternatively, the SRS resource indication information may include an SRI field code point value and may be a single low bit value.

[0046] Optionally, the at least one transmission resource configuration may include at least one SRI field code point information; Optionally, the SRI field codepoint information is associated with at least one SRS resource; Optionally, the SRI field code point information is associated with at least one SRS resource group; Optionally, the terminal can determine, based on the SRI field code point value, a target SRI field code point information indicated by the SRI field code point value among at least one SRI field code point information, and further obtain an SRS resource or an SRS resource group associated with the target SRI field code point information.

[0047] Alternatively, the different SRI field code point values ​​have a one-to-one correspondence with the at least one SRI field code point information, and the correspondence between the different SRI field code point values ​​and the at least one SRI field code point information is pre-indicated by a network side, or pre-defined by a protocol, or pre-configured, or indicated by a second signaling, and the second signaling is an RRC layer signaling or a MAC layer signaling.

[0048] Alternatively, the different SRI field code point values ​​may have a one-to-one correspondence with at least one SRI field code point information, and the terminal can determine target SRI field code point information that has a one-to-one correspondence with the SRI field code point value among the at least one SRI field code point information based on the SRI field code point value.

[0049] Alternatively, the correspondence between different SRI field code point values ​​and the at least one SRI field code point information may be pre-indicated by the network side, pre-defined by a protocol, pre-configured, or indicated by a second signaling, where the second signaling is an RRC layer signaling or a MAC layer signaling.

[0050] Optionally, the correspondence between different SRI field code point values ​​and the at least one SRI field code point information may be described by a table.

[0051] For example, as shown in Table 1 below, the network side configures two SRS resource sets for non-codebook transmission for the UE, and four SRS resources (with indexes 0, 1, 2, and 3) are configured in each resource set, and the UE receives higher layer signaling MAC CE from the network side, which includes four codepoints, where the SRI field of the DCI is 2 bits and corresponds to the four codepoints.

[0052] [Table 1]

[0053] Based on Table 1, when the SRI field code point value of the DCI scheduling PUSCH repeat transmission is 0, it indicates that the PUSCH repeat transmission corresponds to one set of spatial relationships, and all repeat transmission occasions of the PUSCH are transmitted adopting the same spatial relationship as the first SRS resource of the first SRS resource set.

[0054] When the SRI field codepoint value of the DCI for scheduling a PUSCH repeat transmission is 1, this PUSCH repeat transmission corresponds to two sets of spatial relationships, the first spatial relationship is the same as the first SRS resource of the first SRS resource set, and the second spatial relationship is the same as the first SRS resource of the second SRS resource set. The first and second repeat transmission occasions of the PUSCH repeat transmission adopt the first spatial relationship for transmission, and the third and fourth repeat transmission occasions adopt the second spatial relationship for transmission.

[0055] When the SRI field codepoint value of the DCI for scheduling a PUSCH repeat transmission is 2, it indicates that the PUSCH repeat transmission corresponds to two sets of spatial relationships, the first spatial relationship is the same as the second SRS resource of the first SRS resource set, and the second spatial relationship is the same as the first SRS resource of the second SRS resource set. The first and second repeat transmission occasions of the PUSCH repeat transmission adopt the first spatial relationship for transmission, and the third and fourth repeat transmission occasions adopt the second spatial relationship for transmission.

[0056] When the SRI field codepoint value of the DCI scheduling the PUSCH repeat transmission is 3, it indicates that the PUSCH repeat transmission corresponds to one set of spatial relationships, and all the PUSCH repeat transmission occasions are transmitted adopting the same spatial relationship as the second SRS resource of the second SRS resource set.

[0057] For example, as shown in Table 1 below, the network side configures two SRS resource sets for codebook transmission for the UE, and two SRS resources are configured in each resource set, and the UE receives higher layer signaling MAC CE from the network side, which includes four SRI field code point information, where the SRI field of DCI is 2 bits, and can be 00 or 01 or 10 or 11, corresponding to four SRI field code point values.

[0058] [Table 2]

[0059] For example, as shown in Table 2 below, the network side configures two SRS resource sets for non-codebook transmission for the UE, and four SRS resources (with indexes 0, 1, 2, and 3) are configured in each resource set, and the UE receives higher layer signaling MAC CE from the network side, which includes four SRI field code point information, where the SRI field of DCI is 2 bits and can be 00 or 01 or 10 or 11, corresponding to four SRI field code point values.

[0060] [Table 3]

[0061] According to Table 2, if the SRI field codepoint value of the DCI scheduling the PUSCH repeat transmission is 0, it may indicate that the PUSCH repeat transmission corresponds to two SRS resource groups, and the PUSCH transmission occasions are respectively associated with two SRS resource groups. The ports corresponding to the PUSCH transmission occasions associated with the first SRS resource group are the same as the SRS resource(s) with indexes 0, 1, and 2 in the first SRS resource set. The ports corresponding to the PUSCH transmission occasions associated with the second SRS resource group are the same as the SRS resource(s) with indexes 1, 2, and 3 in the first SRS resource set.

[0062] When the SRI field codepoint value of the DCI scheduling the PUSCH repeat transmission is 0, it indicates that the PUSCH repeat transmission corresponds to two SRS resource groups, and the PUSCH transmission occasion is associated with two SRS resource groups, respectively. The port corresponding to the PUSCH transmission occasion associated with the first SRS resource group is the same as the SRS resource(s) with indexes 1 and 2 in the first SRS resource set. The port corresponding to the PUSCH transmission occasion associated with the second SRS resource group is the same as the SRS resource(s) with indexes 2 and 3 in the first SRS resource set.

[0063] When the SRI field codepoint value of the DCI scheduling the PUSCH repeat transmission is 2, it indicates that the PUSCH repeat transmission is associated with one SRS resource group, and the ports corresponding to all transmission occasions of the PUSCH are the same as the SRS resource(s) with indexes 0, 1, 2, and 3 in the first SRS resource set.

[0064] When the SRI field codepoint value of the DCI scheduling the PUSCH repeat transmission is 3, it indicates that the PUSCH repeat transmission is associated with one SRS resource group, and the ports corresponding to all transmission occasions of the PUSCH are the same as the SRS resource(s) with indexes 0, 1, 2, and 3 in the second SRS resource set.

[0065] For example, as shown in Table 3 below, the network side configures two SRS resource sets for codebook transmission for the UE, and two SRS resources are configured in each set. The UE can receive a MAC CE, and the MAC CE activates one SRS resource in each set, that is, if the bit number of the SRI field is 0, there is no need to indicate SRI codepoint information, and the SRI field of the DCI indicates the SRI field codepoint value by 2 bits.

[0066] [Table 4]

[0067] For example, as shown in Table 4 below, the network side configures two SRS resource sets for codebook transmission for the UE, and each set has four SRS resources. The UE receives a MAC CE, and the MAC CE activates the two SRS resources in each set. The two SRS resources may have the same spatial relationship or the same port information, or may not be restricted. In this case, there is no need to indicate SRI field code point information, and the SRI field of the DCI indicates the SRI field code point value by 3 bits / 4 bits.

[0068] [Table 5]

[0069] For example, as shown in Table 5 below, when only one SRS resource is configured in each SRS resource set for codebook transmission configured by the network side, there is no need for the MAC CE to indicate this correspondence, i.e., a separate table. The number of SRI field bits of the DCI is determined by the number of SRS resource sets, and when the SRS resource set is 1, the SRI field of the DCI indicates the SRI field code point value by 0 bit (i.e., no indication is required), and when the SRS resource set is 2, the SRI field of the DCI indicates the SRI field code point value by 2 bits.

[0070] [Table 6]

[0071] Optionally, the multiple SRS resources or resource groups associated with the SRI field codepoint information belong to different SRS resource sets.

[0072] Alternatively, the multiple SRS resources or resource groups associated with the SRI field code point information may belong to different SRS resource sets.

[0073] Alternatively, only one SRS resource, two SRS resources, or four SRS resources may be configured in one SRS resource set.

[0074] Alternatively, only one SRS resource group, two SRS resource groups, or four SRS resource groups may be configured in one SRS resource set.

[0075] Alternatively, if the network side, protocol, MAC layer, or RRC layer configures multiple SRS resource sets for codebook transmission for the terminal, the multiple SRS resources associated with one SRS field code point information are from different SRS resource sets.

[0076] Alternatively, when the network side, protocol, MAC layer, or RRC layer configures multiple SRS resource sets for non-codebook transmission for the terminal, multiple SRS resource groups associated with one code point information may be from different SRS resource sets.

[0077] Alternatively, in each code point information, the number of SRS resources in all SRS resource groups may be the same.

[0078] Alternatively, the number of PUSCH transmission ports of the SRS resource associated with one code point information is the same.

[0079] Optionally, the SRS resources in each of the SRS resource groups belong to the same SRS resource set.

[0080] Alternatively, the SRS resources in each SRS resource group may be from the same SRS resource set.

[0081] Optionally, determining target SRI field code point information among at least one SRI field code point information based on the SRI field code point value in the DCI includes: determining a number of bits of the SRI field based on a number of the at least one SRI field code point information; and determining a range of values ​​of the SRI field code points in the DCI based on the number of bits of the SRI field.

[0082] Alternatively, the number of bits of the SRI field may be determined based on the number of at least one SRI field code point information. For example, if the number of SRI field code point information is 5, the number of bits of the SRI field may be at least 3 bits, and the range of the SRI field code point value may be 000 to 111, i.e., 0 to 7. For example, if the number of SRI field code point information is 4, the number of bits of the SRI field may be at least 2 bits, and the range of the SRI field code point value may be 00 to 11, i.e., 0 to 4.

[0083] Alternatively, when determining the SRS resource indication from the DCI, the SRS resource indication may be determined based on the SRS resource indication and / or based on a range of values ​​of the SRI field codepoint.

[0084] Optionally, transmitting a PUSCH based on the target transmission resource allocation includes: determining an SRS resource associated with a PUSCH repeated transmission occasion according to the target transmission resource configuration; and transmitting a PUSCH based on an SRS resource associated with the repeating transmission occasion.

[0085] Optionally, when the target transmission resource configuration is target SRI field code point information, determine a corresponding SRS resource according to the target SRI field code point information, that is, determine an SRS resource associated with a repeated transmission occasion of the PUSCH; Optionally, after determining the SRS resource associated with the repeated transmission occasion of the PUSCH, the PUSCH may be transmitted based on the SRS resource associated with the repeated transmission occasion.

[0086] Optionally, determining an SRS resource associated with a repeat transmission occasion of a PUSCH based on the target transmission resource configuration includes: Determining a mapping scheme between at least one SRS resource or resource group associated with the target SRI field code point information and a PUSCH transmission occasion; and determining an SRS resource associated with a repeat transmission occasion of the PUSCH based on the mapping scheme.

[0087] Alternatively, when determining a corresponding SRS resource based on the target SRI field code point information, a mapping scheme between at least one SRS resource or resource group related to the target SRI field code point information and a PUSCH transmission occasion may be determined, and an SRS resource related to a PUSCH repeated transmission occasion may be determined based on the mapping scheme.

[0088] As can be understood, the mapping relationship may be understood as a one-to-one correspondence between at least one SRS resource or resource group and a PUSCH transmission occasion.

[0089] Optionally, one transmission occasion of the PUSCH is associated with one or more SRS resources or SRSs.

[0090] Optionally, the transmission spatial relationship and port corresponding to one transmission occasion of the PUSCH are the same as the associated SRS resource or SRS resource group.

[0091] Alternatively, if the number of repeated transmissions of the PUSCH is two or more, the mapping scheme may be The at least one SRS resource or resource group may be interleaved or sequentially mapped with multiple repeated transmission times of the PUSCH.
