[0034] Figure 1The block diagram of a wireless communication system to which the embodiments of the present application can be applied is shown.

Among them, the terminal 11 can be a mobile phone, a tablet personal computer, a laptop computer, a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), an augmented reality (AR), a virtual reality (VR) device, a robot, a wearable device, a flight vehicle, a vehicle user equipment (VUE), a shipborne device, a pedestrian user equipment (PUE), a smart home (home appliances with wireless communication functions, such as refrigerators, TVs, washing machines, or furniture, etc.), a game console, a personal computer (PC), a teller machine, or a self-service machine, etc., which are terminal-side devices.

As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of this application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0035] In addition, for ease of understanding, several technical terms involved in this application are described herein.

[0036] (1) The SRS port is a codebook-based Physical Uplink Shared Channel (PUSCH) transmission. In this regard, the NR protocol TS 38.331 [2] defines that the terminal reports its capability of "maximum supported number of SRS ports". For example, it can be reported through the maxNumberSRS-Ports-PerResource field in the SRS-Resources. Currently, the value range of this field is 1, 2, 4, that is, the terminal supports 1, 2, or 4 SRS ports.

[0037] (2) NR PUSCH non-coherent transmission

[0038] Coherent transmission is defined as a terminal capability. Considering the implementation cost of the terminal, NR does not require all terminals to be able to perform coherent transmission on all antenna ports. NR defines the following 3 types of terminal coherent transmission capabilities.

[0039] Fully-coherent transmission: All antenna ports can perform coherent transmission.

[0040] Partial-coherent transmission: The antenna ports within the same coherent transmission group can perform coherent transmission, while the antenna ports in different coherent transmission groups cannot. Each coherent transmission group contains 2 antenna ports.

[0041] Non-coherent transmission: No antenna ports can perform coherent transmission.

[0042] The NR uplink codebook includes fully coherent codewords for joint transmission of all antenna ports, partially coherent codewords for joint transmission of some antenna ports, and non-coherent codewords for which no antenna ports are jointly transmitted, so as to facilitate the base station to select and indicate the precoding matrix according to the different coherent transmission capabilities of the terminal. Among them, a column in the partially coherent codeword contains non-zero elements corresponding to the same coherent transmission antenna group; a column in the non-coherent codeword contains only one non-zero element.

[0043] (3) Downlink control information (DCI) indicates the layer and precoding matrix of the NR PUSCH

[0044] In Section 7.3.1.1.2 of Protocol TS38.212 [5], the indication method of DCI for "PUSCH transmission layer and precoding matrix" is defined, and only the two cases of 2 antenna ports and 4 antenna ports are defined.

[0045] Based on this, the technical solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

[0046] As Figure 2 shown, it is a schematic flowchart of a method 200 for uplink transmission provided by an exemplary embodiment of the present application. The method 200 can be but is not limited to being executed by a terminal, and can be specifically executed by hardware or software installed in the terminal. In this embodiment, the method 200 can at least include the following steps.

[0047] S210, the terminal obtains target information.

[0048] Among them, the target information includes at least one of terminal capability information, first configuration information, and second configuration information.

[0049] The terminal capability information can be implemented inside the terminal, and is used to indicate the number of antenna ports supported by the terminal. In this embodiment, the number of antenna ports supported by the terminal can be 1, 2, 3, 4, 5, 6, 8, etc., which is not limited here. It can be understood that the "antenna ports" mentioned in the context of the present application can include but are not limited to at least one of SRS ports and PUSCH ports.

[0050] The first configuration information includes at least one of the number of antenna ports (such as 1, 2, 4) in the uplink transmission resource and the port sequence of the antenna ports. In this embodiment, assuming that the uplink transmission resource is the SRS resource or the PUSCH resource, the first configuration information can be understood as the SRS resource configuration (SRS-Config) and the PUSCH resource configuration of the terminal by the network side device. For example, the network side device can perform semi-static configuration through Radio Resource Control (RRC) signaling. For example, the uplink transmission resource can be indicated through the nrofSRS-Ports field in srs-Config.srs-ResourceToAddModList.SRS-Resource in the RRC signaling of rrcReconfiguration. There is no limitation here.

[0051] The second configuration information includes at least one of the number of antenna ports for the target uplink transmission and the port sequence of the antenna ports, that is, the number of antenna ports and the port sequence of the antenna ports actually used by the terminal during the target uplink transmission.

[0052] It should be noted that the second configuration information provided in the embodiments of the present application is based on the pre-configuration of the uplink transmission resource (such as the SRS resource) by the network side. In order to meet the different transmission requirements of different terminals, the second configuration information is further used to re-indicate the number of antenna ports actually used and the port sequence of the antenna ports to the terminal. That is to say, compared with the related art, when the uplink transmission resource is configured for the terminal, the terminal can only use the uplink transmission resource for uplink transmission, resulting in a low flexibility of uplink transmission. In the present application, by additionally introducing the second configuration information, the "uplink transmission resource configuration" and "uplink transmission resource usage" in the related art can be decoupled from strong coupling, that is, the uplink transmission resources configured for the actually used uplink transmission resources can be the same or different. Thus, on the one hand, the flexibility of the network side device to configure the terminal is effectively improved. For example, different antenna ports can be configured for different terminals for uplink transmission. On the other hand, through the configuration of the second configuration information, the terminal can more flexibly determine the relevant information during the target uplink transmission, such as the number of antenna ports and the port sequence, and there is no need to change the uplink transmission resource configuration in the related art, avoiding additional resource overhead.

[0053] Among them, the number of antenna ports for the target uplink transmission in the second configuration information is different from the number of antenna ports in the uplink transmission resource in the first configuration information; or, the port sequence of the antenna ports for the target uplink transmission in the second configuration information is different from the port sequence of the antenna ports in the uplink transmission resource in the first configuration information; or, the number of elements in the port sequence of the antenna ports for the target uplink transmission in the second configuration information is different from the number of antenna ports in the uplink transmission resource included in the first configuration information; or, the number of antenna ports for the target uplink transmission in the second configuration information is different from the number of elements in the port sequence of the antenna ports in the uplink transmission resource included in the first configuration information. Among them, the number of elements can also be understood as the number of serial numbers included in the port sequence. For example, if the port sequence corresponding to 4 antenna ports is {1001, 1002, 1003, 1004}, then the number of elements in this port sequence is 4.

[0054] Optionally, for the foregoing first configuration information and second configuration information, they can be configured through different signaling respectively, or can be configured or carried through the same signaling. Among them, for the case where the first configuration information and the second configuration information are carried through the same signaling, the network-side device can reuse the RRC signaling (such as rrcReconfiguration, etc.) for configuring the first configuration information in related technologies. For example, a new added field is introduced in this RRC signaling to configure and indicate the second configuration information, that is, the second configuration information is carried in the new added field of the RRC signaling.

[0055] Exemplarily, assume that the uplink transmission resource is an SRS resource and the RRC signaling is rrcReconfiguration. Then, in related technologies, the network-side device can indicate the SRS resource (i.e., the foregoing uplink transmission resource) through srs-Config.srs-ResourceToAddModList.SRS-Resource in rrcReconfiguration, such as the number of SRS ports and the port sequence of SRS ports. Then, in order to increase the flexibility of the network-side device to configure the terminal, the network-side device can, in the way of a new added field, configure different SRS ports for different terminals.

[0056] For example, the network-side device can configure the second indication information, i.e., the number of SRS ports actually used by the terminal, such as "3", by introducing a new field, such as nrofSRS-Ports, in srs-Config.srs-ResourceSetToAddModList in rcReconfiguration.

[0057] For another example, the network-side device configures the second indication information, i.e., the port sequence of the SRS ports actually used by the terminal, such as "{0, 1, 2}", by introducing a new field, such as idxofSRS-Ports, in srs-Config.srs-ResourceSetToAddModList in rrcReconfiguration.

[0058] S220, the terminal determines the relevant information of the target uplink transmission according to the target information.

[0059] Wherein, the relevant information of the target uplink transmission may include but is not limited to at least one of the port sequence of the antenna port corresponding to the target uplink transmission and the number of antenna ports.

[0060] It can be understood that similar to the way of determining the relevant information of the target uplink transmission before the terminal performs the target uplink transmission, before receiving the target uplink transmission, the network-side device can also obtain the target information, determine the relevant information of the target uplink transmission according to the target information, and then receive the target uplink transmission according to the relevant information of the target uplink transmission.

[0061] It should be noted that for the case where the relevant information of the target uplink transmission is the number of antenna ports or the port sequence of the antenna ports, the terminal and the network-side device have a consistent understanding of the determination method of the number of antenna ports and the port sequence of the antenna ports, so as to ensure that the relevant information of the target uplink transmission determined by the terminal and the network-side device is consistent.

[0062] For the case where the relevant information of the target uplink transmission is the precoding matrix, the network-side device can monitor the uplink channel of the terminal according to reference signal measurement quantities (such as SRS measurement quantities), etc., determine the precoding matrix corresponding to the target uplink transmission according to the monitoring results, and indicate the determined result to the terminal to guide the terminal to determine the precoding matrix, so as to achieve the purpose of matching the target uplink transmission with the uplink channel.

[0063] In this embodiment, by obtaining the target information and determining the relevant information of the target uplink transmission according to the target information, where the target information includes at least one of terminal capability information, first configuration information, and second configuration information. Thus, the flexibility and applicability of the uplink transmission can be improved.

[0064] In addition, the uplink transmission method provided by this application can also enable the network-side device and the terminal to quickly negotiate and reach an agreement on the relevant information of the target uplink transmission.

[0065] As Figure 3 shown, it is a schematic flowchart of the uplink transmission method 300 provided by an exemplary embodiment of this application. The method 300 can be, but is not limited to, executed by a terminal, and can be specifically executed by hardware or software installed in the terminal. In this embodiment, the method 300 can at least include the following steps.

[0066] S310, the terminal obtains the target information.

[0067] S320, the terminal determines the relevant information of the target uplink transmission according to the target information.

[0068] Among them, the target information includes at least one of terminal capability information, first configuration information, and second configuration information. The terminal capability information is used to indicate the number of antenna ports supported by the terminal; the first configuration information includes at least one of the number of antenna ports in the uplink transmission resource and the port sequence of the antenna ports; the second configuration information includes at least one of the number of antenna ports for the target uplink transmission and the port sequence of the antenna ports.

[0069] It can be understood that the relevant descriptions of S310 - S320 can refer to the descriptions in the foregoing method embodiment 200. Of course, in addition to referring to the descriptions in the foregoing method embodiment 200, as an alternative implementation manner, depending on the different relevant information of the target uplink transmission, the determination process of the terminal based on the target information is also different. The determination process of the relevant information of the target uplink transmission will be described below with reference to Example 1 - Example 2.

[0070] Example 1

[0071] Suppose the relevant information of the target transmission is the number of antenna ports corresponding to the target uplink transmission. Then, the manner in which the terminal determines the number of antenna ports corresponding to the target uplink transmission according to the target information can include at least one of the following Manner 1 - Manner 4.

[0072] Manner 1: Determine the number of antenna ports supported by the terminal indicated by the terminal capability information as the first number; where the first number is the number of antenna ports corresponding to the target uplink transmission.

[0073] That is to say, compared with the prior art where the terminal can only perform uplink transmission according to the number of antenna ports in the uplink transmission resource, in this Mode 1, the terminal ignores the number of antenna ports in the uplink transmission resource and directly determines the number of antenna ports for the target uplink transmission according to the terminal capability information. Thus, the flexibility of the target uplink transmission is effectively improved to meet different transmission requirements of the terminal.

[0074] For example, if the terminal capability information indicates that the number of antenna ports supported by the terminal is 3 and the number of antenna ports in the uplink transmission resource is 4, then the terminal can determine that the number of antenna ports corresponding to the target uplink transmission is 3.

[0075] Mode 2: Determine a first number according to the smaller value between the number of antenna ports supported by the terminal indicated by the terminal capability information and the number of antenna ports in the uplink transmission resource in the first configuration information; wherein, the first number is the number of antenna ports corresponding to the target uplink transmission

[0076] That is to say, compared with the prior art where the terminal can only perform uplink transmission according to the number of antenna ports in the uplink transmission resource, in this Mode 2, the terminal can perform the target uplink transmission according to the smaller value between the number of antenna ports supported by the terminal and the number of antenna ports in the uplink transmission resource in the first configuration information. Thus, the flexibility and applicability of the target uplink transmission are effectively improved.

[0077] For example, if the terminal capability information indicates that the number of antenna ports supported by the terminal is 3 and the number of antenna ports in the uplink transmission resource is 4, then the terminal can determine that the number of antenna ports corresponding to the target uplink transmission is the smaller value of the two, that is, 3.

[0078] Mode 3: Determine a first number according to the smaller value between the number of antenna ports supported by the terminal indicated by the terminal capability information and the number of elements in the port sequence of the antenna ports in the uplink transmission resource in the first configuration information.

[0079] That is to say, compared with the prior art where the terminal can only perform uplink transmission according to the number of antenna ports in the uplink transmission resource, in this Mode 3, the terminal can perform the target uplink transmission according to the smaller value between the number of antenna ports supported by the terminal and the number of elements in the port sequence of the antenna ports in the uplink transmission resource in the first configuration information. Thus, the flexibility and applicability of the target uplink transmission are effectively improved.

[0080] For example, if the terminal capability information indicates that the number of antenna ports supported by the terminal is 3, and the port sequence of the antenna ports in the uplink transmission resource is {1001, 1002, 1003, 1004}, that is, the number of elements in the port sequence is 4, then the terminal can determine that the number of antenna ports corresponding to the target uplink transmission is the smaller value of the two, that is, 3.

[0081] Method 4: Determine the number of antenna ports in the second configuration information for the target uplink transmission or the number of elements in the port sequence as the first number.

[0082] That is to say, compared with the related art where the terminal can only perform uplink transmission according to the number of antenna ports in the uplink transmission resource, in Method 4, the terminal can ignore the number of antenna ports in the uplink transmission resource and instead perform the target uplink transmission according to the number of antenna ports in the second configuration information for the target uplink transmission. Thus, the signaling of "uplink transmission resource configuration" and "uplink transmission resource usage" in the related art can be decoupled from strong coupling. On the one hand, it effectively improves the flexibility of the network-side device in configuring the terminal. For example, different antenna ports can be configured for different users for uplink transmission. On the other hand, through flexible configuration in the form of the second configuration information, it is not necessary to modify the SRS resource configuration and the like in the related art, avoiding additional overhead.

[0083] For example, if the number of antenna ports in the second configuration information for the target uplink transmission is 3, and the number of antenna ports in the uplink transmission resource in the first configuration information is 4, or, then the terminal can determine that the number of antenna ports corresponding to the target uplink transmission is 3.

[0084] For another example, if the number of antenna ports in the second configuration information for the target uplink transmission is 3, and the port sequence of the antenna ports in the uplink transmission resource is {1001, 1002, 1003, 1004}, that is, the number of elements in the port sequence is 4, then the terminal can determine that the number of antenna ports corresponding to the target uplink transmission is the smaller value 3.

[0085] Correspondingly, for the network-side device, the method for the network-side device to determine the number of antenna ports corresponding to the target uplink transmission according to the target information is the same as that of the terminal, so that the network-side device and the terminal can quickly negotiate and reach an agreement on the number of antenna ports for the target uplink transmission to ensure communication consistency.

[0086] It can be understood that when determining the number of antenna ports for the terminal and the network-side device, which specific method among the foregoing methods 1-4 is adopted can be implemented by means such as protocol agreement and high-layer indication. However, no matter which method is adopted, it is necessary to ensure that the methods for the terminal and the network-side device to determine the number of antenna ports are the same.

[0087] Based on this, in an optional implementation manner, if the terminal and the network-side device determine a first number based on any one of the foregoing methods 1-4, that is, the number of antenna ports corresponding to the target uplink transmission, and the first number is less than the number of antenna ports in the uplink transmission resource in the first configuration information, that is, the second number, then when the terminal and the network-side device determine the port sequence of the antenna ports for the target uplink transmission, they can select the first number of elements from the port sequence of the antenna ports in the uplink transmission resource in the first configuration information as the port sequence of the antenna ports for the target uplink transmission.

[0088] Optionally, the foregoing method of "selecting the first number of port sequences from the port sequence of the antenna ports in the uplink transmission resource in the first configuration information" can be implemented by means such as protocol agreement. For example, assume that the first number is 3, the second number is 4, and N < Y, and the antenna port is the SRS port. Then, any one of the following a)-c) can be agreed upon by the protocol.

[0089] a) The protocol stipulates that among the 4 SRS ports (such as 1000-1003) configured by the network-side device, the first 3 SRS ports (that is, 1000-1002) are used for the 3-port uplink SRS transmission of the terminal.

[0090] Based on this, when the terminal determines that the number of antenna ports corresponding to the target uplink transmission is 3, it can determine that the port sequence is 1000-1002.

[0091] b) The protocol stipulates that among the 4 SRS ports (such as 1000-1003) configured by the network-side device, it is agreed that the last 1 SRS port (such as 1003) is not used for the 3-port uplink SRS transmission of the terminal.

[0092] Based on this, when the terminal determines that the number of antenna ports corresponding to the target uplink transmission is 3, it can determine that the port sequence is 1000-1002.

[0093] c) The protocol stipulates that among the 4 SRS ports (such as 1000-1003) configured by the network-side device, the last 1 SRS port (such as 1003) is indicated for "zero power" transmission, that is, it is not used for the 3-port uplink SRS transmission of the terminal.

[0094] Based on this, when the terminal determines that the number of antenna ports corresponding to the target uplink transmission is 3, it can determine that the port sequence is 1000 to 1002.

[0095] Based on the foregoing description, as an alternative implementation, assuming that the determination is based on the first number of antenna ports for the target uplink transmission, then the transmit power of the target uplink transmission can be evenly distributed among the first number of antenna ports, thereby ensuring the uplink transmission quality.

[0096] For example, assume that the first number is 3, and the terminal calculates the transmit power of the target uplink transmission (such as SRS or PUSCH, etc.) as P_dBm through the power control formula, and the conversion to the linear value is as shown in Equation (1).

[0097] P_linear = 1W * 10^(P_dBm / 10) / 1000 (1)

[0098] Based on this, when the terminal uses 3 antenna ports to send the target uplink transmission, the transmit power of each antenna port is P_linear_onePort = P_linear / 3. Wherein, "W" is watt.

[0099] In this Example 1, a simple and flexible uplink transmission scheme is provided, which enables the network side device and the terminal to quickly negotiate and reach an agreement on the antenna ports for the uplink transmission, improving the flexibility of the uplink transmission.

[0100] Example 2

[0101] Assume that the relevant information of the target transmission is the port sequence of the antenna ports corresponding to the target uplink transmission. Then, the manner in which the terminal determines the port sequence of the antenna ports corresponding to the target uplink transmission according to the target information may include at least one of the following Manner 1 - Manner 2.

[0102] Manner 1: Determine according to at least one of the terminal capability information and the first configuration information.

[0103] It should be noted that when determining the port sequence, the number of antenna ports of the target uplink transmission can be determined first in the port number determination manner as described in Example 1. Among them, if the determined number of the target uplink transmission is the same as the number of antenna ports in the uplink transmission resource configured in the first configuration information, then the port sequence of the antenna ports in the uplink transmission resource configured in the first configuration information can be determined as the port sequence of the antenna ports corresponding to the target uplink transmission.

[0104] If the determined number of the target uplink transmissions is less than the number of antenna ports in the uplink transmission resources configured in the first configuration information, then, a part can be selected from the port sequences of the antenna ports in the uplink transmission resources configured in the first configuration information as the port sequence of the antenna ports corresponding to the target uplink transmission, etc. Among them, the selection method of the port sequence can be determined by means such as protocol agreement, and the specific description can refer to the relevant description of the selection method of the antenna ports in the foregoing Example 1.

[0105] Method 2: Determine the port sequence of the antenna ports for the target uplink transmission in the second configuration information as the port sequence of the antenna ports corresponding to the target uplink transmission.

[0106] That is to say, compared with the related art in which the terminal can only perform uplink transmission according to the antenna port sequence in the uplink transmission resources, in Method 2, the terminal can ignore the number of antenna ports in the uplink transmission resources, but perform the target uplink transmission according to the port sequence of the antenna ports for the target uplink transmission in the second configuration information. Thus, the signaling of "SRS resource configuration" and "SRS resource usage" in the related art can be decoupled from strong coupling. On the one hand, it effectively improves the flexibility of the network-side device to configure the terminal. For example, different antenna ports can be configured for different users for uplink transmission. On the other hand, through the flexible configuration in the second configuration information, it is also not necessary to modify the SRS resource configuration, etc. in the related art, avoiding additional overhead.

[0107] Correspondingly, for the network-side device, the method for the network-side device to determine the port sequence of the antenna ports corresponding to the target uplink transmission according to the target information is the same as that of the terminal, so as to ensure communication consistency.

[0108] It can be understood that for the terminal and the network-side device to determine the port sequence of the antenna ports, which of the foregoing Methods 1-2 is specifically adopted can be implemented by means such as protocol agreement and high-layer indication. However, no matter which method is used, it is necessary to ensure that the methods for the terminal and the network-side device to determine the port sequence of the antenna ports are the same.

[0109] In this case, in this embodiment, in addition to the determination of the number of antenna ports and the port sequence of the antenna ports corresponding to the foregoing target uplink transmission, the terminal can also determine the precoding matrix corresponding to the target uplink transmission. The determination process of the precoding matrix will be introduced below in combination with Methods 1-2.

[0110] Method 1: The terminal receives first indication information sent by a network-side device. The first indication information is used to indicate a first precoding matrix, and the terminal determines a precoding matrix corresponding to the target uplink transmission according to the first precoding matrix.

[0111] Wherein, the first precoding matrix is a precoding matrix used for uplink transmission on a second number of antenna ports in the terminal and the network-side device. The second number is the number of antenna ports in the uplink transmission resource or the number of elements in the port sequence in the first configuration information. The number of antenna ports corresponding to the target uplink transmission (i.e., the first number) is less than the second number.

[0112] That is to say, when the number of antenna ports actually used by the terminal for the target uplink transmission is less than the number of antenna ports in the uplink transmission resource in the first configuration information, the network-side device may indicate the first precoding matrix in the uplink transmission resource to the terminal for the terminal to determine a precoding matrix corresponding to the target uplink transmission. Thus, by multiplexing the first precoding matrix in the uplink transmission resource to determine the precoding matrix corresponding to the target uplink transmission, on the one hand, the implementation complexity of the communication system can be reduced. For example, for the precoding matrices corresponding to the first number of antenna ports and the second number of antenna ports, the same codebook search method can be adopted, and the same parsing method can be used for the field indicating "precoding and number of layers" in DCI (scheduling PUSCH). On the other hand, it can also avoid problems such as resource overhead caused by additionally configuring the precoding matrix corresponding to the first number of antenna ports, avoiding resource waste.

[0113] Optionally, when the terminal determines a precoding matrix corresponding to the target uplink transmission according to the first precoding matrix, its implementation method may include at least one of the following.

[0114] (a) Delete or ignore a third number of row vectors from the first precoding matrix, and determine the first precoding matrix after deleting or ignoring the row vectors as the precoding matrix corresponding to the target uplink transmission, where the third number is determined according to the second number and the first number.

[0115] For example, assume the first precoding matrix is for uplink transmission on 4 antenna ports, and the first number is 3. Then, the terminal can delete and ignore the row vector of the last row from the first precoding matrix to obtain That is, the precoding matrix corresponding to the target uplink transmission.

[0116] In one implementation, the terminal can be instructed, through protocol agreement or high-layer configuration, etc., to actually delete or ignore the row vector of a specific row when performing row vector deletion or ignoring, so as to ensure the consistency of understanding of the precoding matrix determination method between the terminal and the network-side device, and further ensure that the precoding matrix determined by the terminal matches the uplink channel.

[0117] (b) Select the first number of row vectors from the first precoding matrix as the precoding matrix corresponding to the target uplink transmission.

[0118] For example, assume that the first precoding matrix is for uplink transmission on 4 antenna ports, and the first number is 3. Then, the terminal can select the row vectors of the first 3 rows from the first precoding matrix to obtain which is the precoding matrix corresponding to the target uplink transmission.

[0119] In one implementation, the terminal can be instructed, through protocol agreement or high-layer configuration, etc., to select the row vectors of which rows as the precoding matrix corresponding to the first number of antenna ports, so as to ensure the consistency of understanding of the precoding matrix determination method between the terminal and the network-side device, and further ensure that the precoding matrix determined by the terminal matches the uplink channel.

[0120] It should be noted that for the network-side device, the precoding matrix corresponding to the target uplink transmission can be determined through the measurement results of reference signals such as SRS, etc. Then, select the precoding matrix that can be used for the target uplink transmission from the precoding matrix, determine it as one of the first precodings, and indicate the first precoding matrix to the terminal through the first indication information.

[0121] In addition, when the network-side device selects the first precoding matrix for determining the precoding matrix corresponding to the target uplink transmission, its implementation process is similar to that of the terminal. For example, the network-side device can first determine which candidate precoding matrix among the candidate precoding matrices for the first number of antenna ports can obtain the precoding matrix corresponding to the target uplink transmission through row vector deletion, ignoring or selection, and then use it as the first precoding matrix and indicate it to the terminal.

[0122] Exemplarily, assume that the first quantity is 3, that is, when the terminal performs the target uplink transmission, it needs to be in the manner of 3 antenna ports and use the precoding matrix corresponding to 4 antenna ports configured in the first configuration information. Then, the terminal can, according to the first precoding matrix indicated by the received first indication information (such as DCI, etc.), that is, the precoding matrix corresponding to 4 antenna ports, and delete or ignore a certain row vector from this first precoding matrix in the manner agreed upon by the protocol, and use the remaining 3 row vectors as the precoding matrix during the target uplink transmission. Thus, on the one hand, it can effectively reduce the complexity of system implementation. For example, for 4 antenna ports and 3 antenna ports, the same codebook search method can be used, and the same parsing method can also be used for the fields indicating "precoding and number of layers" in DCI (scheduling PUSCH). On the other hand, it can also avoid the resource overhead that may be brought by additional codebook configuration.

[0123] Method 2: The terminal receives the second indication information sent by the network-side device, where the second indication information is used to indicate the precoding matrix corresponding to the target uplink transmission, and the terminal selects the precoding matrix corresponding to the target uplink transmission from the first set according to the second indication information.

[0124] Among them, the first set includes at least one candidate precoding matrix. The at least one candidate precoding matrix included in the first set is not configured by the network side for the first number of antenna ports on the terminal, but is determined according to the precoding matrices in the second set. Each precoding matrix in the second set is used for the uplink transmission of the second number of antenna ports, and the second number is greater than the number of antenna ports corresponding to the target uplink transmission, that is, the first number. The second number is the number of antenna ports or the number of elements in the port sequence in the uplink transmission resource in the first configuration information.

[0125] That is to say, for the case where the number of antenna ports actually used by the terminal during the target uplink transmission is less than the number of antenna ports in the uplink transmission resource in the first configuration information, the network-side device can determine the candidate precoding matrix set corresponding to the uplink transmission on the first number of antenna ports, that is, the first set, based on and for the precoding matrix set for the uplink transmission of the second number of antenna ports, that is, the second set, and then select the precoding matrix corresponding to the target uplink transmission from the first set and indicate it to the terminal. Thus, by reusing the first precoding matrix in the uplink transmission resource to determine the precoding matrix corresponding to the target uplink transmission, it can reduce the implementation complexity of the communication system, avoid problems such as resource overhead caused by additional configuration of the precoding matrix corresponding to the first number of antenna ports, and improve resource utilization.

[0126] Based on this, in one implementation manner, the determining manner for at least one candidate precoding matrix included in the first set determined according to the precoding matrices in the second set may include but is not limited to any one of a)-b).

[0127] a) Delete or ignore a third number of row vectors from each precoding matrix in the second set respectively, and determine the first set according to the precoding matrices after deleting or ignoring the row vectors, where the third number is determined according to the second number and the first number, and the first number is the number of antenna ports corresponding to the target uplink transmission.

[0128] b) Select a first number of row vectors from each precoding matrix in the second set respectively, and determine the first set according to the selected row vectors.

[0129] Among them, the determining manner of the first set in this manner 2 is similar to the manner of determining the precoding matrix corresponding to the target uplink transmission based on the first precoding matrix in the foregoing manner 1, and will not be limited herein. It should be noted that when determining the first set, the terminal can be instructed by means such as protocol agreement or high-layer configuration to actually delete or ignore or select which row vector when deleting or ignoring row vectors, so as to ensure the consistency of the understanding of the precoding matrix determination manner between the terminal and the network-side device.

[0130] Based on this, in an optional implementation manner, the precoding matrices included in the first set are non-zero matrices and there are no repetitions among the precoding matrices. Therefore, compared with the manner of scheduling the precoding matrix by the first indication information in manner 1, when scheduling the precoding matrix by the second indication information in this manner 2, signaling overhead can be saved. For example, compared with the first indication information, each second indication information can save 1 bit.

[0131] Exemplarily, assume that the first number is 3, that is, the terminal needs to perform the target uplink transmission in the manner of 3 antenna ports, and continue to use the precoding matrix set corresponding to 4 antenna ports configured in the first configuration information, that is, the second set. Then, as shown in Table 1, it is a table of the Transmitted Precoding Matrix Indicator (TPMI) corresponding to 4 antenna ports agreed by the protocol, which is used for the terminal to determine the precoding matrix according to the DCI sent by the network side. At the same time, as shown in Table 2, it is a TPMI table corresponding to 3 transmit antenna ports determined by the terminal and the network-side device based on the second set.

[0132] Based on this, when the terminal performs target uplink transmission in the manner of 3 transmit antenna ports, the terminal can, as described in Table 2, interpret the corresponding field "Precoding information and number of layers" in the second indication information (such as DCI) to obtain the layer information and TPMI, and then obtain the corresponding precoding matrix from the codebook according to the layer information and TPMI. Among them, since the first set determined based on the second set deletes duplicate or all-zero precoding matrices relative to the second set, the number of precoding matrices in the first set is less than that in the second set. Then, when scheduling the precoding matrix through the second indication information, it is also inevitable to save signaling overhead. For example, the precoding matrix indication information corresponding to Table 1 requires 4-bit overhead, while the precoding matrix indication information corresponding to Table 2 (i.e., the second indication information) only requires 3 bits. That is, the method of providing the precoding matrix determination method in Method 2 can save signaling overhead.

[0133] Table 1

[0134]

[0135] Compared with the method of performing uplink transmission based on a preconfigured precoding matrix in the related art, in this embodiment, by reusing the precoding matrix in the related art, the precoding matrix corresponding to the target uplink transmission is determined. Thus, on the one hand, the complexity of system implementation can be effectively reduced. For example, for 4 antenna ports and 3 antenna ports, the same codebook search method can be used, and the same parsing method can also be used for the field indicating "precoding and number of layers" in indication information such as DCI; on the other hand, the resource overhead that may be brought by additional codebook configuration can be avoided.

[0137]

[0138] Based on the description of the foregoing method embodiments 200-300, for ease of understanding, the following combines Figure 4 An exemplary description of the uplink transmission method provided in this application is as follows.

[0139] S410, the network side device and the terminal respectively obtain target information, such as terminal capability information, first configuration information, and second configuration information.

[0140] For example, the network side device may send RRC signaling to the terminal, and at least one of the first configuration information and the second configuration information is carried in the RRC signaling.

[0141] For example, the terminal may report terminal capability information to the network side device.

[0142] S420. The terminal and the network-side device determine relevant information for the target uplink transmission according to the target information, such as the number of antenna ports, port sequences, etc.

[0143] S430. The network-side device determines a precoding matrix corresponding to the target uplink transmission according to the reference signal measurement quantity.

[0144] S440. Send a first indication message or a second indication message to the terminal. The first indication message is used to indicate a first precoding matrix, and the second indication message is used to indicate the precoding matrix corresponding to the target uplink transmission.

[0145] S450. The terminal determines the precoding matrix corresponding to the target uplink transmission according to the first indication message or the second indication message.

[0146] S460. The terminal sends the target uplink transmission based on the determined number of antenna ports, port sequences, and precoding matrix corresponding to the target uplink transmission. Correspondingly, the network-side device sends the target uplink transmission according to the determined number of antenna ports, port sequences, and precoding matrix corresponding to the target uplink transmission.

[0147] It can be understood that the implementation processes of the steps in this example can refer to the descriptions of the foregoing method embodiments 200-300. To avoid repetition, no further limitations are provided here. In addition, the method for uplink transmission provided in this example may include but is not limited to the foregoing steps, such as it may include more or fewer steps than the foregoing S410-S450.

[0148] Such as Figure 5 As shown, it is a schematic flowchart of a method 500 for uplink transmission provided by an exemplary embodiment of the present application. The method 500 may be, but is not limited to, executed by a network-side device, and may specifically be executed by hardware or software installed in the network-side device.

[0152] It should be noted that when the network-side device obtains the target information, the obtaining method is different according to the difference of the target information.
