[0058] For ease of understanding, some contents involved in the embodiments of the present application are described below:

[0059] 1. Sounding Reference Signal (SRS) for antenna switching.

[0060] Downlink transmission can be based on the channel state information (CSI) reported by the terminal, including precoding matrix and channel quality indicator (CQI) and other information for downlink transmission, or it can be based on SRS to measure the channel state information of the uplink channel. Based on the relevant assumption of channel reciprocity, it is believed that the channel state information of the uplink channel measured based on SRS can be used as downlink channel state information to obtain relevant configuration parameters of downlink transmission.

[0061] In terminal implementation, the number of receiving antennas is generally less than the number of transmitting antennas. Using only uplink antennas to send SRS will result in the network side equipment being unable to fully obtain the performance of downlink transmission. Therefore, SRS transmission for antenna switching is introduced. By switching antenna ports at different times to send different SRS, all antennas can be sent.

[0062] For example, the terminal has only one transmit RF link and two receive RF links. In order to obtain the channel information of the two receive RF links, the terminal reports the 1T2R capability. The network side device configures two SRS resources for the terminal. Different resources are switched to different antenna ports. The network side device can obtain complete downlink channel information by receiving two SRS resources.

[0063] At present, the capability is usually reported from the antenna implementation framework for one terminal. In the case of aggregated reception of multiple terminals, the implementation framework of the sending and receiving antennas of each terminal is different. It is impossible to use the current capability reporting information to assist the network side equipment to configure a suitable SRS to achieve antenna switching. For this reason, the transmission method of the present application is proposed.

[0064] The transmission method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0065] Reference Figure 2 , the present application implements a transmission method, such as Figure 2 As shown, the transmission method includes:

[0066] Step 201: The terminal sends capability information to the network side device, where the capability information includes at least one of antenna switching capability information, power level capability information and first information:

[0067] The antenna switching capability information is used to indicate at least two first antenna switching capability parameter information or one second antenna switching capability parameter information, wherein each of the first antenna switching capability parameter information is associated with a target object, and the second antenna switching capability parameter information is used to indicate the antenna switching capability of at least two target objects transmitting simultaneously;

[0068] The power level capability information is used to indicate at least two first power levels, one second power level or a target power level, the target power level includes the first power level and the second power level, each of the first power levels is associated with a target object, and the second power level is used to indicate the transmit power of at least two target objects transmitting simultaneously;

[0069] The first information includes at least one of the following: at least one first sounding reference signal SRS resource set, the first SRS resource set is an SRS resource set for uplink transmission; downlink transmission corresponding to multiple target information is coherent reception or incoherent reception; the number of channel state information CSI groups corresponding to multiple target information; the corresponding relationship between multiple target information and CSI groups; wherein the target information includes antenna capability or the target object;

[0070] The target object includes at least one of the following: a terminal, an antenna group, an antenna panel, a reference signal, an SRS resource set and beam information.

[0071] In an embodiment of the present application, the above-mentioned antenna grouping, antenna panel, reference signal, SRS resource set and beam information are associated with the terminal, and the above-mentioned first antenna switching capability parameter information can be understood as the antenna switching capability parameter information corresponding to each target object, that is, the corresponding antenna switching capability parameter information when each terminal transmits alone. The above-mentioned second antenna capability information can be understood as the antenna switching capability parameter information of at least two terminals for aggregate transmission. For example, taking two terminals as an example, the antenna switching capability of one terminal can be expressed as 1 transmitting antenna and 2 receiving antennas (1T2R), and the antenna switching capability of the other terminal can be expressed as 2T4R. At this time, the terminal can report two first antenna switching capability parameter information: 1T2R and 2T4R, or it can report one second antenna switching capability parameter information: 3T6R. Since the terminal reports the antenna switching capability information to indicate at least two first antenna switching capability parameter information or one second antenna switching capability parameter information, it can assist the network side device to realize the scheduling of multi-terminal aggregate transmission, thereby improving the uplink and downlink transmission performance.

[0072] Optionally, the first power level can be understood as the power level corresponding to each target object, that is, the power level corresponding to the terminal when transmitting alone. Since at least two first power levels are uploaded, the network side device can assist in configuring the transmission power of the terminal for aggregate transmission. The second power level can be understood as the power level corresponding to the aggregate transmission of at least two terminals. Since the second power level is reported, the network side device can configure the transmission power of the terminal for aggregate transmission based on the second power level.

[0073] Optionally, in some embodiments, the terminal defaults to the first SRS resource set among the multiple SRS resource sets as the first SRS resource set. The SRS resource set used for antenna switching can be understood or replaced by the SRS resource set used for downlink CSI acquisition.

[0074] Optionally, when the terminal reports that the downlink transmission corresponding to the target information is coherent reception or incoherent reception, the network side device can calculate CSI for downlink transmission based on the capabilities reported by the terminal. For example, the terminal reports multiple SRS resource sets, which correspond to the same or different antenna switching capabilities, and the terminal also reports the downlink antenna reception capabilities (such as coherent reception or incoherent reception) corresponding to multiple SRS resource sets. In this way, the network side device can calculate CSI for downlink transmission based on the capabilities reported by the terminal.

[0075] Optionally, when the terminal reports at least one of the number of CSI groups corresponding to multiple target information and the correspondence between multiple target information and CSI groups, the network side device can calculate the channel quality indicator (CQI) based on the reception of multiple SRS resource sets when calculating the downlink (DL) CSI based on the capability information reported by the terminal, and then schedule multi-terminal aggregate transmission based on the CQI. In the case of the target information packet SRS resource set, the SRS resource set can be used for at least one of antenna switching and uplink transmission.

[0076] For example, the terminal reports multiple SRS resource sets, which correspond to the same or different antenna switching capabilities. At the same time, the terminal also reports the CSI groups corresponding to the multiple SRS resource sets. Multiple SRS resource sets can correspond to one CSI group. Based on this capability information, the network side device will calculate a CQI based on the reception of multiple SRS resource sets when calculating the DL CSI.

[0077] For another example, the terminal reports multiple SRS resource sets, which correspond to the same or different antenna switching capabilities respectively. At the same time, the terminal also reports multiple CSI groups corresponding to the multiple SRS resource sets. Based on this capability information, the network side device will calculate multiple CQIs based on the multiple SRS resource sets when calculating the DL CSI.

[0078] Optionally, when the terminal reports the correspondence between the target information and the CSI grouping, the target information can be reported to the network side device in a grouping manner. The target information associated with an SCI grouping can be understood as a target information grouping, that is, the CSI grouping can be understood as a target information grouping, such as an SRS resource set grouping.

[0079] In an embodiment of the present application, capability information is sent to a network side device through a terminal, and the capability information includes antenna switching capability information, power level capability information and at least one of the first information: the antenna switching capability information is used to indicate at least two first antenna switching capability parameter information or one second antenna switching capability parameter information, wherein each of the first antenna switching capability parameter information is associated with a target object, and the second antenna switching capability parameter information is used to indicate the antenna switching capability of at least two target objects transmitting simultaneously; the power level capability information is used to indicate at least two first power levels, one second power level or a target power level, and the target power level includes the first power level and the second power level, each The first power level is associated with a target object, and the second power level is used to represent the transmission power of at least two target objects transmitting simultaneously; the first information includes at least one of the following: at least one first sounding reference signal SRS resource set, the first SRS resource set is an SRS resource set for uplink transmission; the downlink transmission corresponding to multiple target information is coherent reception or incoherent reception; the number of channel state information CSI groups corresponding to multiple target information; the correspondence between multiple target information and CSI groups; wherein the target information includes antenna capability or the target object; wherein the target object includes at least one of the following: terminal, antenna group, antenna panel, reference signal, SRS resource set and beam information. In this way, since the reporting of terminal capability information is clear, it can assist network-side equipment in scheduling multi-terminal aggregate transmission, thereby improving uplink and downlink transmission performance.

[0080] Optionally, in some embodiments, the first antenna switching capability parameter information or the second antenna switching capability parameter information includes x and y, wherein x represents the number of transmitting antenna ports and y represents the number of receiving antenna ports.

[0081] In an embodiment of the present application, the first antenna switching capability parameter information or the second antenna switching capability parameter information can be represented by xTyR, that is, the terminal can report one or more xTyRs, wherein each first antenna switching capability parameter information or the second antenna switching capability parameter information may include one or more xTyRs.

[0082] Optionally, in some embodiments, the first antenna switching capability parameter information satisfies at least one of the following:

[0083] The value of x in the at least two first antenna switching capability parameter information is the same;

[0084] The value of x in each of the first antenna switching capability parameter information is 1, 2 or 4;

[0085] The sum of the values ​​of y in the at least two first antenna switching capability parameter information is 2, 4, 6 or 8.

[0086] In the embodiment of the present application, limiting the value of x in the at least two first antenna switching capability parameter information to be the same can be understood as only terminals with the same transmitting antenna port can perform terminal aggregation, thereby avoiding reporting of the first antenna switching capability parameter information of terminals that cannot be aggregated.

[0087] Optionally, the value of y in different first antenna switching capability parameter information may be the same or different, which is not further limited here.

[0088] Optionally, in some embodiments, the second antenna switching capability parameter information satisfies at least one of the following:

[0089] The value of x in the second antenna switching capability parameter information is 1, 2 or 4;

[0090] The value of y in the second antenna switching capability parameter information is 2, 4, 6 or 8.

[0091] Optionally, in some embodiments, after the terminal sends the capability information to the network side device, the method further includes:

[0092] The terminal receives a first SRS configuration from the network side device, where the first SRS configuration includes a number of SRS ports a, a number of SRS resources b, and the first SRS configuration is used for antenna switching;

[0093] Among them, the value of a is equal to the number x of transmitting antenna ports in the first antenna switching capability parameter information or the second antenna switching capability parameter information, and the value of b is greater than or equal to the target value, and the target value is determined based on a and the number of receiving antenna ports in the first antenna switching capability parameter information or the second antenna switching capability parameter information.

[0094] In an embodiment of the present application, the first SRS configuration may be one or more. When the first SRS configuration is multiple, the multiple first SRS configurations correspond to the first antenna switching capability parameter information one by one, and the target value is determined based on a and the corresponding first antenna switching capability parameter information. Optionally, the target value may be a ratio of a to the number of receiving antenna ports in the first antenna switching capability parameter information or one second antenna switching capability parameter information.

[0095] Optionally, in some embodiments, after the terminal sends the capability information to the network side device, the method further includes:
