In addition, multiple systems can also be combined (for example, a combination of LTE or LTE-A and 5G) for application.

[0106] In a communication system, a terminal can estimate uplink and / or downlink channels by sending an SRS to a network device. The network device configures SRS resources for the terminal to use for SRS transmission. When configuring SRS resources, the network device needs to understand the terminal's SRS-related capabilities and configure SRS resources based on the terminal's capabilities.

[0107] In some embodiments, a terminal may have one or more antenna ports, and the terminal may 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, the SRS resource 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 using the high-level parameter nrofSRS-Ports in the configuration information.

[0108] In the embodiments of the present disclosure, terms such as antenna port, SRS port, physical antenna, and antenna can be used interchangeably.

[0109] The SRS resource may occupy one or more symbols in the time domain (e.g., orthogonal frequency division multiplexing (OFDM) symbols). The symbols occupied by the SRS resource may be continuous in the time domain. In some embodiments, the number of available time domain resources, i.e., the number of symbols that the SRS resource may occupy, may be 1, 2, 4, 8, 10, 12, 14, etc. In some embodiments, the number of symbols occupied by the SRS resource may be configured by a high-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 may be configured by a high-level parameter startPosition in the configuration information.

[0110] Figure 2 is a schematic diagram of a mapping of SRS resources on time-frequency domain resources provided by an embodiment of the present disclosure. As shown in Figure 2, three SRS resources are mapped on the time-frequency domain resources, namely the first SRS resource, the second SRS resource, and the third SRS resource. The first SRS resource occupies 1 symbol in the time domain, and the symbol is the third symbol from the last symbol in the time slot where the first SRS resource is located. The high-level parameters nrofSymbol and startPosition related to the first SRS resource can be 1 and 3, respectively. The second SRS resource occupies 4 symbols in the time domain, and the last symbol of the second SRS resource is the second symbol from the last symbol in the time slot where the second SRS resource is located. The high-level parameters nrofSymbol and startPosition related to the second SRS resource can be 4 and 2, respectively. The third SRS resource occupies 2 symbols in the time domain, and the last symbol of the third SRS resource is the 0th symbol from the last symbol in the time slot where the third SRS resource is located. The third SRS resource-related high-level parameters nrofSymbol and startPosition may be 2 and 0, respectively.

[0111] The SRS resources can be arranged in a comb-like manner in the frequency domain. That is to say, the subcarriers occupied by an SRS resource are arranged at equal intervals. Obviously, the subcarriers occupied by an SRS resource are non-continuous. In some embodiments, the arrangement period of the subcarriers occupied by the SRS resources in the frequency domain can be 2, 4, etc. In some embodiments, the arrangement period of the subcarriers occupied by the SRS resources in the frequency domain can be configured by the high-level parameter transmissionComb in the configuration information. In some embodiments, the offset of the subcarriers occupied by the SRS resources in the frequency domain can be 0, 1, 2, 3, etc. In some embodiments, the offset of the subcarriers occupied by the SRS resources in the frequency domain can be configured by the high-level parameter combOffset in the configuration information.

[0112] Continuing with Figure 2, the first SRS resource is arranged in a comb-like pattern in the frequency domain, with an arrangement period of 2, and the offset of the first occupied subcarrier relative to the first subcarrier (lower edge) of the time-frequency resource is 0. The high-level parameters transmissionComb and combOffset related to the first SRS resource can be 2 and 0, respectively. Similarly, the high-level parameters transmissionComb and combOffset related to the second SRS resource can be 2 and 1, respectively, and the high-level parameters transmissionComb and combOffset related to the third SRS resource can be 4 and 0, respectively.

[0113] In some embodiments, the mapping of an 8-port SRS resource (i.e., an SRS resource supporting 8 SRS ports) to time-frequency resources can be performed using either time division multiplexing (TDM) or non-TDM. In some embodiments, whether the 8-port SRS resource uses the TDM method can be configured using the higher-level parameter transmissionComb in the configuration information. In some embodiments, for the non-TDM method, the mapping of the 8-port SRS resource to time-frequency resources can be achieved by arranging different combinations of period, subcarrier offset, and cyclic shift. In one example, the higher-level parameter transmissionComb associated with the 8-port SRS resource can be 2, and different cyclic shifts can be used. In another example, the higher-level parameter transmissionComb associated with the 8-port SRS resource can be 4 or 8, and different subcarrier offsets and cyclic shifts can be used. In some embodiments, for the TDM method, 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 two SRS port subsets. Each SRS port subset can include 4 SRS ports. For example, a first subset of SRS ports may include ports 0, 1, 4, 5, and a second subset of SRS ports may include ports 2, 3, 6, 7.

[0114] With the development of wireless communication technology, a terminal may have three transmitting antennas, where the three transmitting antennas are physical antennas. In this case, the terminal needs to report its own terminal capabilities to the network device so that the network device can configure SRS resources for the terminal.

[0115] The embodiments of the present disclosure provide a terminal capability reporting method for three transmitting antennas (hereinafter referred to as the terminal capability reporting method), a device, and a storage medium to implement terminal capability reporting for a terminal with three transmitting antennas.

[0116] In some embodiments, for a terminal with three transmit antennas (which may be denoted as Tx) (i.e., a terminal with three transmit antennas), the number of receive antennas (which may be denoted as Rx) is Y, and Y may be configured as an integer greater than 3. In one example, Y = 4, 6, or 8.

[0117] In some embodiments, the terminal RF architecture is a combination of transmit antennas (Tx) and receive antennas (Rx). In one example, the terminal RF architecture may include one of three transmit antennas and four receive antennas (3Tx / 4Rx), three transmit antennas and six receive antennas (3Tx / 6Rx), and three transmit antennas and eight receive antennas (3Tx / 8Rx).

[0118] In some embodiments, a terminal RF architecture of "xTx / yRx" corresponds to an antenna switching configuration denoted as "xTyR." In one example, a terminal RF architecture of 3Tx / 4Rx corresponds to an antenna switching configuration denoted as "3T4R," a terminal RF architecture of 3Tx / 6Rx corresponds to an antenna switching configuration denoted as "3T6R," and a terminal RF architecture of 3Tx / 8Rx corresponds to an antenna switching configuration denoted as "3T8R."

[0119] In some embodiments, the terms "antenna switching type", "antenna switching configuration", "antenna switching pattern" and the like may be used interchangeably.

[0120] In some embodiments, terms such as "x transmit antennas and y receive antennas," "xTx / yRx," and "xTyR" may be used interchangeably. In one example, "3 transmit antennas and 4 receive antennas" may be replaced by "3Tx / 4Rx" or "3T4R." In another example, "3 transmit antennas and 6 receive antennas" may be replaced by "3Tx / 6Rx" or "3T6R." In another example, "3 transmit antennas and 8 receive antennas" may be replaced by "3Tx / 8Rx" or "3T8R."

In one example, the value of the usage information element may be equal to "codebook," indicating that the function is codebook. For example, the value range of the usage information element may be {beamManagement, codebook, nonCodebook, antennaSwitching}. Therefore, for terminal 101, the value of the usage information element in the first information may be equal to codebook.

In one embodiment, the network device can be configured so that the 3-port SRS resources associated with the 3 transmit antennas of the terminal can be composed of one or more SRS resources. For the case where the 3-port SRS resources are composed of multiple SRS resources, the terminal needs to send the second information to the network device to indicate whether the terminal itself supports sending these multiple SRS resources at the same time domain position.

In one example, the value of the usage information element may be equal to "antennaSwitching," indicating that the function is antenna switching. For example, the value range of the usage information element may be {beamManagement, codebook, nonCodebook, antennaSwitching}. Therefore, for terminal 101, the value of the usage information element in the first information may be equal to "antennaSwitching." Of course, the fifth information may also be other information elements or signaling, which is not specifically limited in the present embodiment.

[0166] In some embodiments, when the function of the SRS resource set of the terminal is antenna switching, the first information includes at least one of the following: the maximum number of SRS resource sets based on antenna switching supported by the terminal, the maximum number of uplink MIMO transmission layers supported by the terminal, the maximum number of SRS resources in the SRS resource set based on antenna switching supported by the terminal, the maximum number of non-periodic SRS resources in an SRS resource set based on antenna switching supported by the terminal, third information, and fourth information.

[0169] In some embodiments, the maximum number of uplink MIMO transmission layers supported by a terminal is the MIMO-LayersUL information element.

[0172] In some embodiments, the third information may be a supportedSRS-TxPortSwitch information element. In one example, the value range of supportedSRS-TxPortSwitch may be {3T4R, 3T6R, 3T8R}. 3T4R represents 3 transmit antenna ports and 4 receive antenna ports, 3T6R represents 3 transmit antenna ports and 6 receive antenna ports, and 3T8R represents 3 transmit antenna ports and 8 receive antenna ports.

[0175] In some embodiments, when the number of receiving antennas of a terminal is greater than three, the terminal transmits SRS by antenna switching. Therefore, an antenna switching transmission gap is inserted between SRS resources. In one embodiment, an antenna switching transmission gap can be inserted between every two SRS resources, or an antenna switching transmission gap can be inserted between SRS resources whenever an antenna switch occurs.

[0176] In one example, when N SRS resources used to transmit SRS belong to the same SRS resource set, the fourth information may indicate that the terminal supports inserting an antenna switching transmission interval between the last symbol of the i-th SRS resource and the first symbol of the i+1-th SRS resource, where N is a positive integer and i is a positive integer less than or equal to N-1. Alternatively, the fourth information may indicate that the terminal supports inserting an antenna switching transmission interval between the last symbol of the i-th SRS resource and the first symbol of the i+1-th SRS resource. j The last symbol of the SRS resource is the same as the nth symbol after the jth switching. j+1 An antenna switching transmission interval is inserted between the first symbols of the SRS resources, where n j and n j+1 is a positive integer less than or equal to 3, j is a positive integer less than or equal to X-1, X is the number of times the receiving antenna is switched, and X is a positive integer.

[0185] In some embodiments, the sixth information may be a resourceType information element. In one example, the value range of the resourceType information element may be {periodic, semi-persistent, aperiodic}. Therefore, for terminal 101, the value of the resourceType information element in the first information may be equal to any one of periodic, semi-persistent, and aperiodic. Of course, the sixth information may also be other information elements or signaling, which is not specifically limited in the present embodiment.
