Abstract: This disclosure provides methods, devices and systems for channel sounding for wireless communications. Some implementations more specifically relate to scheduling sounding reference signal (SRS) resource sets for wireless devices having more than 4 receive (RX) antenna ports. In some implementations, a base station may determine an antenna switching capability of a user equipment (UE). The antenna switching capability indicates a number of RX antenna ports of the UE. The base station schedules a number of SRS resource sets for the UE based at least in part on the number of RX antenna ports in excess of four. For example, the number of RX antenna ports may be equal to 8. As another example, the number of RX antenna ports may be equal to 6. The base station further receives, from the UE, uplink transmissions of one or more SRS resources for each of the scheduled SRS resource sets.

Abstract: A method of wireless communication, by a user equipment (UE) supporting a four transmitter/six receiver (4T6R) antenna configuration, reports a sounding reference signal (SRS) switching capability. The method receives an SRS antenna switching configuration, and performs SRS antenna switching while transmitting multiple SRSs via SRS resources with multiple transmitters for different antenna ports, in accordance with the SRS antenna switching configuration. At least one of the different antenna ports may use at least two of the SRS resources. A quantity of the different antenna ports assigned to each SRS resource may be different for the SRS antenna switching. The UE may sound the different antenna ports an equal number of times, and at least one of the different antenna ports may use at least two of the SRS resources for the SRS antenna switching.

Abstract: Aspects relate to configuring active groups of antenna ports. An apparatus may support different groups of antenna ports. One or more of these groups may be designated as active (e.g., for a scheduled transmission). In some examples, a first apparatus may send to a second apparatus an indication of the active groups. The second apparatus may then use the active groups for a transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may receive a capability message from a user equipment (UE) based on a number of receive antennas exceeding a number of transmit antennas at the UE. The base station may configure the UE with a mapping between sounding reference signal (SRS) resources and bit sequences, or SRS resource indices (SRIs), based on the capability message. The base station may transmit a control message including one or more SRIs indicating respective SRS resources. The UE may use the one or more SRIs included in a control message from the base station to select respective SRS resources from a resource set. Once the UE selects one or more SRS resources, the UE may transmit one or more SRSs in the SRS resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive. from a base station, signaling that indicates an indirect assignment of a slot for transmitting sounding reference signals (SRSs) in multiple SRS resource sets. The UE may determine whether the slot is available for the indirect assignment based on a first set of characteristics associated with the multiple SRS resource sets and a second set of characteristics associated with the slot. If the UE determines that the slot is available for the indirect assignment, the UE may transmit SRSs in the multiple SRS resource sets during the slot. If the UE determines that the slot is unavailable for the indirect assignment. the UE may refrain from transmitting SRSs in one or more of the multiple SRS resource sets during the slot.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, configuration information regarding one or more available slots associated with transmitting sounding reference signal (SRS) information. The UE may receive, from the base station, dynamic downlink communication including slot information for determining a select available slot from among the one or more available slots. The UE may transmit, to the base station, the SRS information during the select available slot, determined based at least in part on the slot information and the configuration information. Numerous other aspects are described.

Abstract: Aspects of the present disclosure provide various devices, methods, and systems for dynamic spectrum sharing of a spectrum between different radio access technologies and multiple frequency division duplexing modes. Dynamic spectrum sharing (DSS) is a technology that allows wireless network operators to share a spectrum between different radio access technologies (RATs). DSS allows an operator to dynamically allocate some existing 4G spectrum to 5G use to deliver 5G services using a shared spectrum.

Abstract: Aspects of the disclosure relate to radio access networks with a capability to dynamically reconfigure a number of transmission-reception points (TRPs) in a single-frequency network (SFN) based on channel measurements. In one example, a mobile device receives a configuration message including a plurality of transmission configuration indicator (TCI) states, and potentially further including an indication identifying one or more of the TCI states as main TCI states. The message may further include an indication that it includes the plurality of TCI states. The UE receives a downlink traffic channel and demodulates the traffic channel based on only a subset of the TCI states (e.g., the main TCI state (s)). The UE further measures one or more channel parameters corresponding to each TCI state of the plurality of TCI states, and transmits a channel state information report based on the channel parameters. Other aspects, embodiments, and features are also claimed and described.

Abstract: Aspects of the present disclosure include methods, apparatuses, and computer readable media for configuring sounding reference signal (SRS) transmissions on subband full-duplex (SBFD) slots. In an example, a user equipment (UE) may determine a change from a first uplink (UL) bandwidth pattern to a second UL bandwidth pattern occurred within in a sub-band full duplex (SBFD) bandwidth. The UE may also configure one or more settings for a sounding resource signal (SRS) transmission based on the second UL bandwidth pattern. The UE may also transmit, to a base station, the SRS transmission according to the one or more settings for the SRS transmission.
