The method 200 may optionally be applied to Figure 1 The system shown in the figure is not limited thereto. The method 200 may optionally be executed by a terminal. The method 200 includes at least part of the following contents.

[0121] In 210, the terminal determines resource or signal indication information.

[0122] Optionally, the resource or signal indication information is used to indicate a resource, or to indicate a signal.

[0123] In 220, the terminal determines an uplink or downlink signal that is quasi-co-located with the PUCCH to be transmitted according to the resource or signal indication information.

[0124] Optionally, the quasi-co-location of the PUCCH to be transmitted and the uplink or downlink signal includes: the quasi-co-location of the PUCCH to be transmitted and the uplink or downlink signal with respect to a spatial reception parameter.

[0125] It should be understood that the PUCCH to be transmitted is quasi-co-located with the uplink or downlink signal with respect to the spatial reception parameters, which means that the terminal can assume that the beam used to send the PUCCH to be transmitted is similar to or the same as the direction of the beam used to send or receive the uplink or downlink signal.

[0126] It should be understood that although most of the present application uses quasi-co-location as an example for quasi-co-location of spatial reception parameters, the embodiments of the present application are not limited to this. For example, the quasi-co-location of the embodiments of the present application can be quasi-co-location for other large-scale parameters such as Doppler frequency shift, Doppler spread, delay spread, average delay, average gain, etc.

[0127] Optionally, when the resource or signal indication information indicates a signal, the terminal determines the signal indicated by the resource or signal indication information as the uplink or downlink signal that is quasi-co-located with the PUCCH to be transmitted.

[0128] Optionally, the signal indicating the resource or signal information may be a signal sent before the PUCCH to be transmitted is sent.

[0129] Optionally, when the resource or signal indication information indicates a resource, the terminal determines the signal transmitted on the resource indicated by the resource or signal indication information as the uplink or downlink signal that is quasi-co-located with the PUCCH to be transmitted.

[0130] Optionally, the signal transmitted on the resource indicated by the resource or signal indication information may be a signal sent before the PUCCH to be transmitted is sent.

[0131] In 230, the terminal sends the PUCCH to be transmitted by utilizing the quasi co-location relationship between the PUCCH to be transmitted and the uplink or downlink signal.

[0132] Optionally, the terminal determines the transmission beam of the PUCCH to be transmitted by utilizing the quasi-co-location relationship between the PUCCH to be transmitted and the uplink or downlink signal; and transmits the PUCCH to be transmitted by utilizing the determined transmission beam.

[0133] Specifically, the terminal may determine the transmission beam of the PUCCH to be transmitted by utilizing the quasi-co-location relationship between the PUCCH to be transmitted and the uplink or downlink signal with respect to the spatial parameters.

[0134] In one method, when the signal quasi-co-located with the PUCCH to be transmitted is an uplink signal, the transmit beam of the uplink signal is determined as the transmit beam of the PUCCH to be transmitted, and a transmit beam with a direction close to that of the transmit beam of the uplink signal can also be determined as the transmit beam of the PUCCH to be transmitted.

[0135] In another manner, when the signal quasi-co-located with the PUCCH to be transmitted is a downlink signal, the receiving beam of the downlink signal is determined as the transmitting beam of the PUCCH to be transmitted, or the receiving beam with a direction close to that of the receiving beam of the downlink signal can be determined as the transmitting beam of the PUCCH to be transmitted.

[0136] Optionally, since the best beams used by the terminal to send PUCCH at different times may be different, the terminal may obtain resource or signal indication information in real time.

[0137] Therefore, in an embodiment of the present application, the terminal can obtain the first uplink and downlink signals that are quasi-co-located with the PUCCH to be transmitted based on the resources or signals indicated by the resource or signal indication information, and use the quasi-co-located relationship between the PUCCH to be transmitted and the uplink or downlink signal to send the PUCCH to be transmitted, thereby avoiding blindly sending the PUCCH to be transmitted, achieving reasonable sending of the PUCCH to be transmitted, and improving communication performance.

[0138] Furthermore, the terminal can select the transmit beam of the PUCCH to be transmitted according to the transmit or receive beam of the signal transmitted on the resource indicated by the resource or signal indication information, or according to the transmit or receive beam of the signal indicated by the resource or signal indication information. A more suitable transmit beam for the PUCCH to be transmitted can be selected to achieve a greater beamforming gain, thereby further improving communication performance.

[0139] Figure 3 3 is a schematic flow chart of a wireless communication method 300 according to an embodiment of the present application. The method 300 includes at least part of the following contents.

[0140] In 310, the terminal determines resource or signal indication information.

[0141] Optionally, the resource or signal indication information is used to indicate a resource, or to indicate a signal.

[0142] In 320, the terminal determines the transmission beam of the PUCCH to be transmitted according to the resource or signal indication information.

[0143] Optionally, based on the reception or transmission beam of the first signal indicated by the resource or signal indication information, the terminal determines the transmission beam of the PUCCH to be transmitted.

[0144] Optionally, the first signal indicated by the resource or signal indication information may be a signal sent before the PUCCH is sent.

[0145] Optionally, when the first signal is an uplink signal, the terminal determines the transmission beam of the first signal as the transmission beam of the PUCCH to be transmitted, or determines a transmission beam similar to the transmission beam direction of the first signal as the transmission beam of the PUCCH to be transmitted.

[0146] Optionally, when the first signal is a downlink signal, the terminal determines the receiving beam of the first signal as the transmitting beam of the PUCCH to be transmitted, or determines a receiving beam close to the direction of the receiving beam of the first signal as the transmitting beam of the PUCCH to be transmitted.

[0147] Optionally, based on the reception or transmission beam of the second signal transmitted on the resource indicated by the resource or signal indication information, the terminal determines the transmission beam of the PUCCH to be transmitted.

[0148] Optionally, the second signal transmitted on the first resource or the resource indicated by the signal may be a signal sent before the PUCCH is sent.

[0149] Optionally, when the second signal is an uplink signal, the terminal determines the transmit beam of the second signal as the transmit beam of the PUCCH to be transmitted, or determines a transmit beam close to the transmit beam direction of the second signal as the transmit beam of the PUCCH to be transmitted.

[0150] Optionally, when the second signal is a downlink signal, the receiving beam of the second signal is determined as the transmitting beam of the PUCCH to be transmitted, or the receiving beam with a direction close to the receiving beam of the second signal is determined as the receiving beam of the PUCCH to be transmitted.

[0151] In 330, the terminal sends the PUCCH to be transmitted using the determined transmission beam of the PUCCH to be transmitted.

[0152] Therefore, the terminal selects the transmission beam of the PUCCH to be transmitted according to the resource or signal indication information, and can select a more suitable transmission beam for the PUCCH to be transmitted to achieve a greater beamforming gain, thereby further improving the communication performance.

[0153] The above briefly introduces method 200 and method 300 respectively, and the content introduced below is applicable to both methods 200 and 300.

[0154] Optionally, the resource or signal indication information is sounding reference signal (Sounding Reference Signal, SRS) resource indication information, used to indicate one SRS resource among at least one SRS resource.

[0155] Specifically, the terminal can send SRS separately on at least one SRS resource. After receiving the SRS sent by the terminal, the network device can select an SRS resource (for example, an SRS resource carrying the best signal quality of the SRS) from the at least one SRS resource, and indicate the selected SRS to the terminal through SRS resource indication information.

[0156] Optionally, when the terminal sends SRS on multiple SRS resources, the transmission beams of different SRS resources may be different.

[0157] Optionally, each SRS resource of at least one SRS resource may have independent configuration parameters compared to other SRS resources, for example, an independent SRS transmission period, an independent SRS triggering method, an independent transmission beam, or an independent number of SRS transmissions when triggered to send SRS.

[0158] Optionally, the terminal may determine the SRS resources on which the SRS needs to be sent according to preset information.

[0159] Optionally, the resource or signal indication information is channel state information reference signal (CSI-RS) resource indication information, used to indicate a CSI-RS resource among at least one CSI-RS resource.

[0160] Specifically, the network device can send CSI-RS respectively on at least one CSI-RS resource, the terminal can receive the CSI-RS sent by each CSI-RS resource in the at least one CSI-RS resource, and obtain channel state information (Channel State Information, CSI) respectively, and send it to the network device. The network device can select a CSI-RS resource (for example, a CSI-RS resource with the best channel quality) from at least one CSI-RS resource according to the CSI corresponding to each CSI-RS resource, and indicate it to the terminal through CSI-RS resource indication information.

[0161] Optionally, when the terminal receives CSI-RS in different CSI-RS resources, the received beams adopted may be different.

[0162] Optionally, each CSI-RS resource of the at least one CSI-RS resource may have independent configuration parameters compared to other CSI-RS resources, for example, an independent CSI-RS transmission period and the like.

[0163] Optionally, the terminal may determine the CSI-RS resource on which the CSI-RS needs to be received according to preset information.

[0164] Optionally, the resource or signal indication information is synchronization signal block indication information, used to indicate a synchronization signal block in at least one synchronization signal block.

[0165] Optionally, the network device may randomly select a synchronization signal block from at least one synchronization signal block, or select a synchronization signal block with better or optimal synchronization performance for the terminal, and indicate it to the terminal through synchronization signal block indication information.

[0166] Optionally, the terminal may determine, based on preset information, a synchronization signal block that may be used to select for synchronization.

[0167] Optionally, the terminal determines the type of the resource or signal indication information according to whether beam reciprocity is available; and determines the resource or signal indication information having this type.

[0168] Optionally, the type of resource or signal indication information can be distinguished by the type of resource or signal indicated, for example, including three types: CSI-RS resource indication information, SRS resource indication information or synchronization signal block indication information.

[0169] In one embodiment, when the beam reciprocity is available, the terminal determines that the type of the resource or signal indication information is CSI-RS resource indication information or synchronization signal block indication information; wherein the CSI-RS resource indication information is used to indicate a CSI-RS resource in at least one CSI-RS resource, and the synchronization signal block indication information is used to indicate a synchronization signal block in at least one synchronization signal block;

[0170] In one manner, when beam reciprocity of the terminal is not available, it is determined that the type of the resource or signal indication information is SRS resource indication information, and the SRS resource indication information is used to indicate one SRS resource among at least one SRS resource.

[0171] It is described above that the terminal can determine the type of resource or signal indication information according to whether the beam reciprocity of the terminal is available.

[0172] In the embodiment of the present application, the network device may also indicate which type of resource or signal indication information the terminal uses to determine the uplink or downlink signal quasi-co-located with the PUCCH to be transmitted based on whether the beam reciprocity of the terminal is available, so that the terminal can use the type of resource or signal indication information indicated by the network to obtain the resource or signal indication information. The beam reciprocity of the terminal used by the network device may be notified to the network device by the terminal.

[0173] The above describes the content related to the types of resource or signal indication information, and the following describes the way in which the terminal obtains the resource or signal indication information. The resource or signal indication information obtained below can be any type of resource or signal indication information mentioned above.

[0174] Method 1): The terminal obtains the resource or signal indication information from the downlink control information DCI of the physical downlink shared channel PDSCH corresponding to the PUCCH to be transmitted.

[0175] Optionally, the PUCCH to be transmitted is used to carry a positive acknowledgement ACK command or a negative acknowledgement NACK command of downlink transmission, and the PDSCH carries the downlink transmission.

[0176] Optionally, according to the resource or signal indication information, the terminal determines the size of the power adjustment value corresponding to the transmit power control (TPC) command for the PUCCH to be transmitted carried in the DCI.

[0177] Specifically, different values ​​of the resource or signal indication information may correspond to different TPC mapping tables, which are used to determine the correspondence between the TPC command and the power adjustment value. The power adjustment value may be an absolute value (i.e., the power value to be adjusted) or an accumulated value (i.e., the value to be adjusted based on the original power value).

[0178] Optionally, the terminal determines, based on the resource or signal indication information, a closed-loop power control process to which the TPC command for the PUCCH to be transmitted carried in the DCI belongs.

[0179] Specifically, the resource or signal indication information can be used not only to determine the transmit beam of the PUCCH to be transmitted, but also to determine the current closed-loop power control process. The terminal determines in which closed-loop power control process the power adjustment value corresponding to the TPC command is accumulated based on the resource or signal indication information. The corresponding relationship between the value of the resource or signal indication information and the closed-loop power control process can be preset on the terminal, or configured to the terminal by the network device.

[0180] Mode 2): The terminal obtains the resource or signal indication information from the most recently received DCI for scheduling the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH).

[0181] In this implementation, the PUCCH to be transmitted may be used to carry an ACK command or a NACK command for downlink transmission or to carry CSI.

[0182] Method 3), obtaining the resource or signal indication information from the DCI, the DCI only includes the TPC command for the PUCCH and the resource or signal indication information for the PUCCH, and the first DCI includes the TPC command for the PUCCH to be transmitted and the resource or signal indication information for the PUCCH to be transmitted.

[0183] In this implementation, the PUCCH to be transmitted may be used to carry an ACK command or a NACK command for downlink transmission or to carry CSI.

[0184] Specifically, the resource or signal indication information of the PUCCH to be transmitted may be indicated together with the TPC command of the PUCCH to be transmitted.

[0185] For example, the first DCI includes N information fields, each of which includes a TPC command for a PUCCH and resource or signal indication information of the PUCCH. The terminal obtains the index of the information field corresponding to the PUCCH to be transmitted in all information fields of the DCI through high-layer signaling.

[0186] Method 4), obtaining the resource or signal indication information from high-level signaling.

[0187] In this implementation, the PUCCH to be transmitted may be used to carry an ACK command or a NACK command for downlink transmission or to carry CSI.

[0188] Mode 5): determining the resource or signal indication information according to the power control process used by the PUCCH to be transmitted.

[0189] In this implementation, the PUCCH to be transmitted may be used to carry an ACK command or a NACK command for downlink transmission or to carry CSI.

[0190] Specifically, the network device configures multiple power control processes for the terminal and indicates the power control process used by the terminal for the PUCCH to be transmitted. The terminal determines the resource or signal indication information according to the process used, wherein the corresponding relationship between the process and at least one resource or signal indication information (that is, at least one information value) can be pre-set on the terminal, or configured to the terminal by the network device.

[0191] Mode 6): The terminal obtains the resource or signal indication information from the CSI reporting configuration corresponding to the first CSI, and the PUCCH to be transmitted is used to transmit the first CSI.

[0192] In this implementation, the PUCCH to be transmitted can be used to carry CSI.

[0193] From the above introduction of various methods for obtaining resource or signal indication information, it can be seen that the resource or signal indication information is obtained through information from the network device. Therefore, the network device can flexibly adjust the beam used by the terminal to transmit PUCCH.

[0194] The above introduces a variety of methods for obtaining resource or signal indication information. The specific method to be adopted can be determined according to the PUCCH format of the PUCCH to be transmitted, and the method for obtaining the first resource or signal can be determined; the resource or signal indication information is obtained according to the determined acquisition method.

[0195] For example, for a PUCCH format that can be used to transmit CSI, method 2), 3), 4), 5) or 6) may be used to obtain resource or signal indication information.

[0196] For example, for a PUCCH format that can be used to transmit a NACK command or an ACK command, method 1), 2), 3), 4), or 5) may be used to obtain resource or signal indication information.

[0197] Optionally, different PUCCH formats use different acquisition methods for resources or signals. The format of the PUCCH for sending a NACK command or an ACK command may be acquired in a different manner from the format of the PUCCH for sending CSI.

[0198] Optionally, for different PUCCH formats, the resource or signal indication information may also be acquired in the same manner, for example, by using high-layer signaling to acquire the resource or signal indication information.

[0199] At this time, independent signaling or different information fields of the same signaling may be used to indicate resources or signal indication information corresponding to different PUCCH formats.

[0200] Therefore, in an embodiment of the present application, the terminal determines how to send the PUCCH to be transmitted (for example, determines the transmission beam) based on the resource or signal indication information, which can achieve more reasonable sending of the PUCCH to be transmitted and improve communication performance.

[0202] Optionally, the processing unit 410 is used to: determine resource or signal indication information; determine an uplink or downlink signal that is quasi-co-located with the PUCCH to be transmitted based on the resource or signal indication information; and the communication unit 420 is used to: send the PUCCH to be transmitted by utilizing the quasi-co-located relationship between the PUCCH to be transmitted and the uplink or downlink signal.
