In a communication system, a terminal may estimate an uplink channel and/or a downlink channel by transmitting an SRS to a network device. The network device configures SRS resources for the terminal for transmitting SRS. When configuring SRS resources, the network device needs to know the capability of the terminal related to SRS and configure SRS resources for the terminal according to the capability of the terminal.

In some embodiments, the terminal may have one or more antenna ports, and the terminal may transmit SRS through the one or more antenna ports. In this case, the SRS resource 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 SRS resources may be 1, 2, 4, 8, etc. In some embodiments, the number of SRS Ports may be configured by high-level parameters nrofSRS-Ports in the configuration information.

In the embodiments of the present disclosure, terms of antenna port, SRS port, physical antenna, etc. may be replaced with each other.

The SRS resources may occupy one or more symbols (e.g., orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbols) in the time domain. Symbols occupied by SRS resources may be consecutive in the time domain. In some embodiments, the number of symbols that the available time domain resources, i.e., SRS resources, may occupy may be 1, 2, 4, 8, 10, 12, 14, etc. In some embodiments, the number of symbols occupied by SRS resources may be configured by higher layer parameters nrofSymbol in the configuration information.

Fig. 2 is a schematic diagram of mapping SRS resources on time-frequency domain resources according to an embodiment of the disclosure. As shown in fig. 2,3 SRS resources, that is, a first SRS resource, a second SRS resource, and a third SRS resource, are mapped on the time-frequency domain resource. The first SRS resource occupies 1 symbol in the time domain, and the symbol is the 3 rd symbol with the last symbol in the slot where the first SRS resource is located as the starting point forward number. The first SRS resource related higher layer parameters nrofSymbol and startPosition may 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 2 nd symbol of the starting point of the last symbol in the slot where the second SRS resource is located. The second SRS resource related higher layer parameters nrofSymbol and startPosition may 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 0 th symbol of the starting point forward number of the last symbol in the slot where the third SRS resource is located. The third SRS resource related higher layer parameters nrofSymbol and startPosition may be 2 and 0, respectively.

The SRS resources may be arranged in a comb-like manner in the frequency domain. That is, subcarriers occupied by one SRS resource are arranged at equal intervals. Obviously, the subcarriers occupied by one SRS resource are discontinuous. In some embodiments, the arrangement period of subcarriers occupied by SRS resources on the frequency domain may be 2, 4, etc. In some embodiments, the arrangement period of the subcarriers occupied by SRS resources on the frequency domain may be configured by a higher layer parameter transmissioncombo in the configuration information. In some embodiments, the offset of the subcarriers occupied by SRS resources in the frequency domain may be 0, 1, 2, 3, etc. In some embodiments, the offset of the subcarriers occupied by SRS resources in the frequency domain may be configured by higher layer parameters combOffset in the configuration information.

With continued reference to fig. 2, the first SRS resources are arranged in a comb shape in the frequency domain with an arrangement period of 2 and an offset of 0 of the occupied first subcarrier relative to the first subcarrier (lower edge) of the time-frequency resources. The higher layer parameters transmissioncombs and combOffset associated with the first SRS resource may be 2 and 0, respectively. Similarly, the higher-layer parameters transmissioncombs and combOffset related to the second SRS resource may be 2 and 1, respectively, and the higher-layer parameters transmissioncombs and combOffset related to the third SRS resource may be 4 and 0, respectively.

In some embodiments, mapping of 8-port SRS resources (i.e., SRS resources with 8 number of SRS ports supported) on time-frequency resources may take both time division multiplexing (time division multiplexing, TDM) and non-TDM forms. In some embodiments, whether the 8-port SRS resource is configured in a TDM manner may be configured by a higher layer parameter transmissioncombo in the configuration information. In some embodiments, for non-TDM approaches, mapping of 8-port SRS resources on time-frequency resources may be achieved by arranging different combinations of periodicity, subcarrier offset, and cyclic shift. In an example, the 8-port SRS resource related higher layer parameter transmissioncombo may be 2 and employ a different cyclic shift. In an example, the 8-port SRS resource related higher layer parameter transmissioncombo may be 4 or 8 and employ different subcarrier offsets and different cyclic shifts. In some embodiments, for TDM mode, the 8-port SRS resource may occupy multiple symbols. In an example, the 8-port SRS resource may occupy 2 symbols. At this time, 8 SRS ports corresponding to the 8-port SRS resource may be divided into 2 SRS port subsets. Each SRS port subset may include 4 SRS ports. For example, a first SRS port subset may include ports 0, 1, 4,5, and a second SRS port subset may include ports 2,3, 6, 7.

With the development of wireless communication technology, a terminal may have 3 transmitting antennas, where the 3 transmitting antennas are physical antennas, and in this case, the terminal needs to report its own terminal capability to a network device, so that the network device configures SRS resources for the terminal.
