Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0124] In a communication system, a terminal can estimate the uplink and / or downlink channels by sending SRS (Sentence Responsive Analysis) to a network device. The network device configures SRS resources for the terminal to send SRS. When configuring SRS resources, the network device needs to be aware of the terminal's SRS-related capabilities and configure the SRS resources accordingly.

[0125] In some embodiments, a terminal may have one or more antenna ports, and the terminal can transmit SRS through one or more antenna ports. In this case, the SRS resources configured by the network device for the terminal may correspond to the number of antenna ports of the terminal. More specifically, SRS resources may have one or more SRS ports, and the number of SRS ports may correspond to the number of antenna ports of the terminal. In some embodiments, the number of SRS ports supported by the SRS resource may be 1, 2, 4, 8, etc. In some embodiments, the number of SRS ports may be configured through the higher-level parameter nrofSRS-Ports in the configuration information.

[0126] In the embodiments of this disclosure, the terms "antenna port", "SRS port", "physical antenna", and "antenna" can be used interchangeably.

[0127] In some embodiments, SRS resources may occupy one or more symbols in the time domain (e.g., orthogonal frequency division multiplexing (OFDM) symbols). The symbols occupied by SRS resources may be continuous in the time domain. In some embodiments, the number of available time-domain resources, i.e., the number of symbols that SRS resources can occupy, may be 1, 2, 4, 8, 10, 12, 14, etc. In some embodiments, the number of symbols occupied by SRS resources can be configured by the higher-level parameter nrofSymbol in the configuration information. In some embodiments, the position of the starting symbol of the SRS resource may be 0, 1, 2, 3, 4, 5, etc. In some embodiments, the position of the starting symbol of the SRS resource can be configured by the higher-level parameter startPosition in the configuration information.

[0128] In some embodiments, FIG2 is a schematic diagram of the mapping of SRS resources in the time-frequency domain according to embodiments of the present disclosure. As shown in FIG2, three SRS resources are mapped in the time-frequency domain: SRS resource A, SRS resource B, and SRS resource C. SRS resource A occupies 1 symbol in the time domain, and this symbol is the 3rd symbol counting backwards from the last symbol in the time slot where SRS resource A is located. The higher-level parameters nrofSymbol and startPosition related to SRS resource A can be 1 and 3, respectively. SRS resource B occupies 4 symbols in the time domain, and the last symbol of SRS resource B is the 2nd symbol counting backwards from the last symbol in the time slot where SRS resource B is located. The higher-level parameters nrofSymbol and startPosition related to SRS resource B can be 4 and 2, respectively. SRS resource C occupies 2 symbols in the time domain, and the last symbol of SRS resource C is the 0th symbol counting backwards from the last symbol in the time slot where SRS resource C is located. The high-level parameters nrofSymbol and startPosition related to SRS resource C can be 2 and 0, respectively.

[0129] In some embodiments, SRS resources can be arranged in a comb pattern in the frequency domain. That is, the subcarriers occupied by an SRS resource are arranged at equal intervals. Obviously, the subcarriers occupied by an SRS resource are not continuous. In some embodiments, the arrangement period of the subcarriers occupied by the SRS resource in the frequency domain can be 2, 4, etc. In some embodiments, the arrangement period of the subcarriers occupied by the SRS resource in the frequency domain can be configured by the higher-layer parameter transmissionComb in the configuration information. In some embodiments, the offset of the subcarriers occupied by the SRS resource in the frequency domain can be 0, 1, 2, 3, etc. In some embodiments, the offset of the subcarriers occupied by the SRS resource in the frequency domain can be configured by the higher-layer parameter combOffset in the configuration information.

[0130] Referring again to Figure 2, SRS resource A is arranged in a comb pattern in the frequency domain with a period of 2, and the offset of the first subcarrier occupied relative to the first subcarrier (lower edge) of the time-frequency resource is 0. The higher-layer parameters transmissionComb and combOffset associated with SRS resource A can be 2 and 0, respectively. Similarly, the higher-layer parameters transmissionComb and combOffset associated with SRS resource B can be 2 and 1, respectively, and the higher-layer parameters transmissionComb and combOffset associated with SRS resource C can be 4 and 0, respectively.

[0131] In some embodiments, the mapping of 8-port SRS resources (i.e., SRS resources supporting 8 SRS ports) on time-frequency resources can employ either time division multiplexing (TDM) or non-TDM methods. In some embodiments, whether the 8-port SRS resource uses TDM can be configured via the higher-layer parameter `transmissionComb` in the configuration information. In some embodiments, for non-TDM methods, the mapping of 8-port SRS resources on time-frequency resources can be achieved through different combinations of arrangement period, subcarrier offset, and cyclic shift. In one example, the higher-layer parameter `transmissionComb` associated with the 8-port SRS resource can be 2, and different cyclic shifts are used. In another example, the higher-layer parameter `transmissionComb` associated with the 8-port SRS resource can be 4 or 8, and different subcarrier offsets and different cyclic shifts are used. In some embodiments, for TDM methods, the 8-port SRS resource can occupy multiple symbols. In one example, the 8-port SRS resource can occupy 2 symbols. In this case, the 8 SRS ports corresponding to the 8-port SRS resource can be divided into 2 SRS port subsets. Each SRS port subset can include 4 SRS ports. For example, the first SRS port subset may include ports 0, 1, 4, and 5, and the second SRS port subset may include ports 2, 3, 6, and 7.

[0132] With the development of wireless communication technology, terminals may have three transmit antennas. To support terminals with three transmit antennas, the implementation scheme for the antenna switching SRS configuration needs further discussion. Therefore, how to enhance the antenna switching configuration of a terminal with three transmit antennas is a problem that urgently needs to be solved.

[0133] This disclosure provides a communication method, device, and storage medium for a terminal with three transmitting antennas, thereby enhancing the antenna switching configuration of a terminal with three transmitting antennas.

[0134] In some embodiments, for a terminal with 3 transmit antennas (which can be denoted as Tx) (i.e., a terminal with 3 transmit antennas), the number of receive antennas (which can be denoted as Rx) is Y, where Y can be configured as an integer greater than 3. In one example, Y = 4, 6, or 8.

[0135] In some embodiments, the combination of the terminal's transmitting antenna (Tx) and receiving antenna (Rx) may include one of three transmitting antennas and four receiving antennas (3Tx / 4Rx), three transmitting antennas and six receiving antennas (3Tx / 6Rx), or three transmitting antennas and eight receiving antennas (3Tx / 8Rx).

[0136] In one example, as shown in Figure 3, which is a schematic diagram of a terminal radio frequency architecture provided according to an embodiment of the present disclosure, (a) shows a 3Tx / 4Rx terminal radio frequency architecture, (b) shows a 3Tx / 6Rx terminal radio frequency architecture, (c) shows a 3Tx8 / Rx terminal radio frequency architecture, and (d) shows another 3Tx / 8Rx terminal radio frequency architecture.

[0137] In some embodiments, the terminal RF architecture of "xTx / yRx" corresponds to the antenna switching configuration denoted as "xTyR". In one example, the terminal RF architecture of 3Tx / 4Rx corresponds to the antenna switching configuration denoted as "3T4R", the terminal RF architecture of 3Tx / 6Rx corresponds to the antenna switching configuration denoted as "3T6R", and the terminal RF architecture of 3Tx / 8Rx corresponds to the antenna switching configuration denoted as "3T8R".

[0138] In some embodiments, terms such as "antenna switching configuration" and "antenna switching pattern" can be used interchangeably.

[0139] In some embodiments, terms such as "x transmit antennas and y receive antennas," "xTx / yRx," and "xTyR" can be interchanged. In one example, "3 transmit antennas and 4 receive antennas" can be replaced with one of "3Tx / 4Rx" or "3T4R." In one example, "3 transmit antennas and 6 receive antennas" can be replaced with one of "3Tx / 6Rx" or "3T6R." In one example, "3 transmit antennas and 8 receive antennas" can be replaced with one of "3Tx / 8Rx" or "3T8R."

[0140] As shown in Figure 3, when the terminal sends SRS, it needs to traverse all receiving antennas through antenna switching (AS, also known as antenna rotation) to achieve downlink channel state estimation.

[0141] The following describes the communication method (hereinafter referred to as the communication method) for a terminal with three transmitting antennas provided in this disclosure, in conjunction with different terminal radio frequency architectures.

[0152] In one example, for a terminal with 3 transmit antennas and 6 receive antennas (i.e., 3Tx / 6Rx), that is, x = 3 and y = 6. For the 3Tx / 6Rx RF architecture, the antenna switching configuration set (denoted as set 3) may include at least one of the following antenna switching configurations: 1 transmit port and 1 receive port (1T1R), 2 transmit ports and 2 receive ports (2T2R), 1 transmit port and 2 receive ports (1T2R), 1 transmit port and 3 receive ports (1T3R), 1 transmit port and 4 receive ports (1T4R), 2 transmit ports and 3 receive ports (2T3R), 2 transmit ports and 4 receive ports (2T4R), 3 transmit ports and 3 receive ports (3T3R), 3 transmit ports and 4 receive ports (3T4R), 1 transmit port and 6 receive ports (1T6R), 2 transmit ports and 6 receive ports (2T6R), and 3 transmit ports and 6 receive ports (3T6R).

[0153] In one example, for a terminal with 3 transmit antennas and 6 receive antennas (i.e., 3Tx / 6Rx), where x = 3 and y = 6, the antenna switching configuration set (denoted as set 4) for the 3Tx / 6Rx RF architecture can include at least one of the following antenna switching configurations: 1 transmit port and 1 receive port (1T1R), 2 transmit ports and 2 receive ports (2T2R), 1 transmit port and 2 receive ports (1T2R), 1 transmit port and 3 receive ports (1T3R), 1 transmit port and 4 receive ports (1T4R), 2 transmit ports and 4 receive ports (2T4R), 3 transmit ports and 3 receive ports (3T3R), 3 transmit ports and 4 receive ports (3T4R), 1 transmit port and 6 receive ports (1T6R), 2 transmit ports and 6 receive ports (2T6R), and 3 transmit ports and 6 receive ports (3T6R).

[0154] In some embodiments, the terminal can determine its supported antenna switching configurations based on at least one of one or more antenna switching configuration sets (such as at least one antenna switching configuration), an unsupported first antenna switching configuration, and an unsupported second switching configuration. In some embodiments, an unsupported first antenna switching configuration can be understood as an antenna switching configuration that the terminal's hardware implementation does not support. In one example, the number of receive ports in the first antenna switching configuration is 3 or 4. In some embodiments, an unsupported second antenna switching configuration can be understood as an antenna switching configuration with unbalanced port transmit power. In one example, the second antenna switching configuration may include at least one of the following: 3T4R, 2T3R.

[0155] In some embodiments, the terminal can determine the antenna switching configurations it supports based on one or more antenna switching configuration sets (such as at least one antenna switching configuration). In this case, the terminal can select an antenna switching configuration set based on its own hardware implementation and determine the antenna switching configurations it supports from at least one antenna switching configuration in that set. In one example, the terminal's RF architecture is 3Tx / 4Rx, and the terminal can determine that it supports antenna switching configurations in set 1 or set 2. In another example, the terminal's RF architecture is 3Tx / 6Rx, and the terminal can determine that it supports antenna switching configurations in set 3 or set 4. In this case, the terminal can support all antenna switching configurations in the determined antenna switching configuration set.

[0156] In some embodiments, the terminal may also determine its supported antenna switching configuration based on line switching configurations it does not support. In some embodiments, the terminal may also determine its supported antenna switching configuration based on a first antenna switching configuration it does not support. In some embodiments, the terminal may also determine its supported antenna switching configuration based on a second antenna switching configuration it does not support. In some embodiments, the terminal may also determine its supported antenna switching configuration based on a first antenna switching configuration and a second antenna switching configuration that it does not support. In this case, the terminal may support at least one default antenna switching configuration other than the unsupported antenna switching configuration (such as at least one of the first and second antenna switching configurations).

[0157] In some embodiments, the terminal may also determine its supported antenna switching configuration based on one or more antenna switching configuration sets and unsupported antenna switching configurations (such as at least one of the first antenna switching configuration and the second antenna switching configuration). In some embodiments, the terminal may also determine its supported antenna switching configuration based on one or more antenna switching configuration sets and unsupported first antenna switching configurations. In some embodiments, the terminal may also determine its supported antenna switching configuration based on one or more antenna switching configuration sets and unsupported second antenna switching configurations. In some embodiments, the terminal may also determine its supported antenna switching configuration based on one or more antenna switching configuration sets, unsupported first antenna switching configurations, and unsupported second antenna switching configurations. In this case, the terminal may first select one or more antenna switching configuration sets according to its own hardware implementation, and then determine an antenna switching configuration other than unsupported antenna switching configurations (such as at least one of the first antenna switching configuration and the second antenna switching configuration) from at least one antenna switching configuration in the selected antenna switching configuration set.

[0158] In some embodiments, the terminal does not support an antenna switching configuration with 3 receive ports. In one example, an antenna switching configuration with 3 receive ports may include at least one of the following: 1 transmit port and 3 receive ports (1T3R), 2 transmit ports and 3 receive ports (2T3R), or 3 transmit ports and 3 receive ports (3T3R).

[0159] In some embodiments, the terminal does not support an antenna switching configuration with 4 receive ports. In one example, an antenna switching configuration with 4 receive ports may include at least one of the following: 1 transmit port and 4 receive ports (1T4R), 2 transmit ports and 4 receive ports (2T4R), or 3 transmit ports and 4 receive ports (3T4R).

[0160] It should be noted that, for different radio frequency architectures, the antenna switching configurations that the terminal does not support may include other antenna switching configurations, and the number of receiving ports may also be other values. This disclosure does not specifically limit these aspects.

[0161] In some embodiments, the SRS configuration associated with the second antenna handover configuration can indicate a first SRS resource and a second SRS resource, where the number of ports in the second SRS resource is not equal to the number of ports in the first SRS resource. In some embodiments, the number of ports in the first SRS resource (denoted as N1) is less than the number of ports in the second SRS resource (denoted as N2), and the transmit power of each port on the symbol containing the first SRS resource (e.g., an orthogonal frequency division multiplexing (OFDM) symbol) is higher than the transmit power of each port on the symbol containing the second SRS resource. This situation affects the performance of downlink channel state estimation; therefore, the terminal may consider not supporting antenna handover configurations with unbalanced port transmit power. In some embodiments, the number of ports in the first SRS resource (denoted as N1) is greater than the number of ports in the second SRS resource (denoted as N2), and the transmit power of each port on the symbol containing the first SRS resource is lower than the transmit power of each port on the symbol containing the second SRS resource. This situation affects the performance of downlink channel state estimation; therefore, the terminal may consider not supporting antenna handover configurations with unbalanced port transmit power.

[0162] In some embodiments, the second antenna handover configuration is 3T4R, and the associated SRS resource can be a combination of one 1-port SRS resource and one 3-port SRS resource. In this case, the transmit power of the symbol containing the 1-port (N1=1) SRS resource (i.e., the first SRS resource) is higher than the transmit power of each port on the symbol containing the 3-port (N2=3) SRS resource (i.e., the second SRS resource). The transmit power of the symbol containing the first SRS resource is three times the transmit power of each port on the symbol containing the second SRS resource.

[0163] In some embodiments, the second antenna handover configuration is 2T3R, and the associated SRS resource can be a combination of one 1-port SRS resource and one 2-port SRS resource. In this case, the transmit power of the symbol containing the 1-port (N1=1) SRS resource (i.e., the first SRS resource) is higher than the transmit power of each port on the symbol containing the 2-port (N2=3) SRS resource (i.e., the second SRS resource). The transmit power of the symbol containing the first SRS resource is twice the transmit power of each port on the symbol containing the second SRS resource.

[0164] In some embodiments, the first SRS resource and the second SRS resource may belong to the same SRS resource set or to different SRS resource sets.

[0165] In some embodiments, the first antenna switching configuration and the second antenna switching configuration may be the same or different. In some embodiments, when there are multiple first antenna switching configurations and multiple second antenna switching configurations, the multiple first antenna switching configurations and the multiple second antenna switching configurations may or may not overlap.

[0166] In one example, for a terminal with 3 transmit antennas and 4 receive antennas (i.e., 3Tx / 4Rx), where x = 3 and y = 4, the terminal may not support antenna switching configurations with 3 receive ports.

In this case, the antenna switching configurations supported by the terminal include at least one of the following: 1 transmit port and 1 receive port (1T1R), 2 transmit ports and 2 receive ports (2T2R), 1 transmit port and 2 receive ports (1T2R), 1 transmit port and 3 receive ports (1T3R), 3 transmit ports and 3 receive ports (3T3R), 1 transmit port and 6 receive ports (1T6R), 2 transmit ports and 6 receive ports (2T6R), and 3 transmit ports and 6 receive ports (3T6R).

[0196] In one example, for a terminal with 3 transmit antennas and 6 receive antennas (i.e., 3Tx / 6Rx), where x = 3 and y = 6, the terminal may not support antenna switching configurations with 3 receive ports or 2T3R. In this case, the antenna switching configurations supported by the terminal include at least one of the following: 1 transmit port and 1 receive port (1T1R), 2 transmit ports and 2 receive ports (2T2R), 1 transmit port and 2 receive ports (1T2R), 1 transmit port and 4 receive ports (1T4R), 2 transmit ports and 4 receive ports (2T4R), 3 transmit ports and 4 receive ports (3T4R), 1 transmit port and 6 receive ports (1T6R), 2 transmit ports and 6 receive ports (2T6R), and 3 transmit ports and 6 receive ports (3T6R).

[0197] In one example, for a terminal with 3 transmit antennas and 6 receive antennas (i.e., 3Tx / 6Rx), where x = 3 and y = 6, the terminal may not support antenna switching configurations with 4 receive ports or 2T3R. In this case, the antenna switching configurations supported by the terminal include at least one of the following: 1 transmit port and 1 receive port (1T1R), 2 transmit ports and 2 receive ports (2T2R), 1 transmit port and 2 receive ports (1T2R), 1 transmit port and 3 receive ports (1T3R), 3 transmit ports and 3 receive ports (3T3R), 1 transmit port and 6 receive ports (1T6R), 2 transmit ports and 6 receive ports (2T6R), and 3 transmit ports and 6 receive ports (3T6R).

[0198] In step S402, the terminal determines its ability to support antenna switching intervals.

[0199] In some embodiments, the terminal's support capability for antenna switching gap (AS gap) includes at least one of the following: whether the terminal supports antenna switching with an antenna switching gap length of 0, and the supported antenna switching gap.

[0200] In one example, the antenna switching interval is the switching time required when a physical antenna or transmission channel is switched, and its value is related to the subcarrier spacing. Specific values ​​can be seen in Table 1 below.

[0201] Table 1

[0202] In some embodiments, the terminal's ability to support antenna switching intervals may be associated with subcarrier intervals.

[0203] In some embodiments, the terminal determines whether it supports antenna switching with an antenna switching interval length of 0. In some embodiments, the length of the antenna switching interval is the number of time units occupied by the antenna switching interval. Therefore, an antenna switching interval length of 0 means that the number of time units occupied by the antenna switching interval is 0. In this case, when the terminal sends SRS, it does not add an antenna switching interval between adjacent SR resource sets, thus achieving antenna switching with no switching delay.

[0204] In some embodiments, the terminal may also determine the length of the antenna switching interval it supports.

[0205] In some embodiments, the antenna switching interval may occupy one or more time units. The number of time units occupied by the antenna switching interval can be understood as the length of the antenna switching interval. In one example, the length of the antenna switching interval supported by the terminal includes at least one of the following: 0 time units, 1 time unit, and 2 time units. In one example, the terminal supports antenna switching intervals occupying at least one of 0 time units, 1 time unit, and 2 time units. In one example, the terminal supports at least one of antenna switching intervals occupying 0 time units, antenna switching intervals occupying 1 time unit, and antenna switching intervals occupying 2 time units.

[0206] In some embodiments, the time unit is a symbol, a cyclic prefix (CP) length, etc. In one example, the antenna switching interval supported by the terminal includes at least one of the following: 0 symbols, 1 symbol, and 2 symbols. In one example, the terminal supports an antenna switching interval occupying at least one of 0 symbols, 1 symbol, and 2 symbols. In one example, the terminal supports an antenna switching interval occupying 0 symbols, an antenna switching interval occupying 1 symbol, and an antenna switching interval occupying 2 symbols. In one example, the antenna switching interval supported by the terminal includes at least one of the following: 0 CP length, 1 CP length, and 2 CP length. In one example, the terminal supports an antenna switching interval occupying at least one of 0 CP length, 1 CP length, and 2 CP length. In one example, the terminal supports an antenna switching interval occupying at least one of 0 CP length, an antenna switching interval occupying 1 CP length, and an antenna switching interval occupying 2 CP length.

[0207] In some embodiments, the terminal may also determine the number of antenna switching intervals it supports. In one example, the number of antenna switching intervals can be 0, 1, or 2. In some embodiments, the number of antenna switching intervals is 0, indicating that no antenna switching interval needs to be added between SRS resources, thus achieving zero switching delay for antenna switching.

[0208] In step S403, the terminal sends the first information.

[0209] In some embodiments, the network device receives first information.

In one example, the value of the usage cell may be equal to "antennaSwitching," indicating that the function is antenna switching. For example, the value range of the usage cell may be {beamManagement, codebook, nonCodebook, antennaSwitching}. Therefore, for the terminal, the value of the usage cell in the first information may be equal to "antennaSwitching." Of course, the second information may also be other cells or signaling, and this disclosure does not specifically limit this.

[0216] In some embodiments, the first information may further include third information. The third information is used to indicate the antenna switching configuration supported by the terminal.

[0221] Through the embodiments of this disclosure, a terminal with three transmitting antennas reports its antenna switching support capability to the network, so that the network device can configure SRS resources corresponding to different antenna switching configurations for the terminal according to the terminal's antenna switching support capability, thereby enhancing the antenna switching configuration; furthermore, it can avoid incomplete downlink channel state information caused by the incompatibility between the antenna switching configuration configured by the network and the terminal's own capabilities, thereby reducing the loss of downlink throughput.
