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: Methods, systems, and devices for wireless communications are described to indicate a single frequency network (SFN) mode and associated composite channel reference signals to a user equipment (UE). A UE and a base station may communicate via two or more transmission and reception points (TRPs) using an SFN transmission, which may represent a transmission having multiple beam configurations. The base station may transmit a configuration associated with a control channel that explicitly or implicitly indicates whether control channel transmissions are associated with an SFN mode or are configured with multiple candidate beam configurations. The base station may transmit an indication of activated beam configurations for the control channel. The UE may receive one or more reference signals from each TRP and, based on the SFN indication, may use information from the one or more reference signals to receive the control channel transmission.

Abstract: Methods, systems, and devices for wireless communications are described to support complexity reduction for a control resource set (CORESET). A low complexity user equipment (UE) may experience reduced performance if a number of resource block (RB) groups in a CORESET is above a given threshold, or if any symbols of a CORESET are multiplexed with any other signal or channel. A base station may configure a CORESET for a low complexity UE to support reduction in complexity of information detection compared with a CORESET configured for other UEs. The configured CORESET may be based on one or more capabilities of a low complexity UE and may include a reduced number of RB groups or may avoid overlapping with any other signal or channel. If a CORESET configured for a low complexity UE is does not support complexity reduction, the UE may suppress decoding search space candidates on the CORESET.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine downlink (DL) channel state information; and transmit a first sounding reference signal (SRS) and a second SRS, wherein the second SRS is precoded based at least in part on the DL channel state information. Numerous other aspects are provided.

Abstract: A method of wireless communication at a user equipment (UE) includes receiving, from a network node, a message indicating slots for transmitting a transport block on a physical uplink shared channel (PUSCH). The method also includes segmenting the transport block into code blocks. The method further includes encoding the code blocks to produce encoded code blocks. Each code block may be encoded at a coding path from a group of coding paths associated with a coding chain. The method still further includes transmitting the encoded code blocks in the slots on the PUSCH.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a user equipment (UE) may receive. from a base station, control signaling for a first sounding reference signal. The UE may determine, based on the configuration and a set of parameters associated with partial frequency sounding of the first sounding reference signal, a subset of a set of re sources configured for the first sounding reference signal, where the subset of the set of resources excludes at least one resource of the set of resources. The UE may transmit, to the base station, a second sounding reference signal over the subset of the set of resources.

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.
