Abstract: A user equipment (UE) may identify at least one suitable configuration for sounding reference signal (SRS) antenna switching and transmit the at least one suitable configuration for SRS antenna switching to the base station via a medium access control (MAC) control element (CE) (MAC-CE) or a radio resource control (RRC) message. The base station may receive the at least one suitable configuration for SRS antenna switching from the UE, and transmit an active SRS antenna switching configuration to the UE, the active SRS antenna switching configuration based on the suitable configuration for SRS antenna switching received from the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit configuration signaling such as radio resource control (RRC) signaling to a user equipment (UE) which indicates a number of sounding reference signal (SRS) resource sets and respective SRS resources within each of the SRS resource sets that may be used for channel estimation. The base station may subsequently transmit a control message such as a medium access control (MAC) control element (CE) to the UE, which indicates an activation status for at least one SRS resource within the SRS resource set. Basedon the indicated activation status for the at least one SRS resource, the UE may transmit one or more SRSs to the base station.

Abstract: Aspects of the disclosure relate to utilizing SRS resources for various types of usages and configuring transmit power on the SRS resources. In an aspect, a user equipment (UE) may determine whether a time gap between a first sounding reference signal (SRS) resource for a first usage and a second SRS resource for a second usage in time is less than a time threshold. Further, the UE may transmit an SRS utilizing one of the first SRS resource or the second SRS resource for both the first usage and the second usage, in response to determining that the time gap is less than the time threshold.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a base station using antenna groups configured at a user equipment (UE) for CSI reporting. The base station may transmit an indication of the antenna group that the UE is to use for measuring and reporting CSI. Based on the received indication, the UE may measure a reference signal transmitted by the base station and received at the UE using one or more antennas of the antenna group in accordance with the indication. The UE may transmit, to the base station, a CSI report that is based on the measuring of the reference signal using the one or more antennas of the antenna group.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a first channel state information (CSI) for a first group of antennas of the UE and a second CSI for a second group of antennas of the UE, where the first group of antennas are different than the second group of antennas. The UE may transmit one or more of the first CSI or the second CSI in a CSI report. Numerous other aspects are provided.

Abstract: In some scenarios, SRS transmission over the full SRS bandwidth may be unnecessary and/or inefficient. Therefore, a need exists for approaches to SRS transmission over less than the full SRS bandwidth. Described herein are techniques and solutions of SRS transmission using only a portion of the full SRS bandwidth, or a partial SRS bandwidth. The present disclosure provides for SRS transmission using a partial SRS bandwidth through sounding patterns that use only the partial SRS bandwidth and/or using a partial SRS bandwidth through various SRS sequence generation configured for the partial SRS bandwidth. An apparatus receives an SRS configuration indicating a full SRS bandwidth; determines a frequency hopping pattern for SRS transmission based on the SRS configuration, and the frequency hopping pattern is limited to a partial SRS bandwidth less than the full SRS bandwidth; and transmits the SRS transmission to the base station based on the frequency hopping pattern.

Abstract: Aspects for time bundling an SRS resource over a plurality of instances are disclosed. The apparatus may include a user equipment (UE). The user equipment may receive a configuration from a base station for time-bundling at least one sounding reference signal (SRS) resource. The time-bundling may be performed by the UE transmitting a plurality of SRS signals at different times using an identical center frequency and at least two different frequency resource allocations. The UE may transmit the plurality of SRS signals based on the configuration.

Abstract: A configuration for a device to interleave a codeword, where the codeword is based on an enhanced noncoherent error correction code. The apparatus encodes a set of bits based on a noncoherent error correction code to generate a first codeword. The apparatus interleaves the first codeword to permute coded bits of the first codeword into a second codeword. The apparatus transmits the second codeword to a second device.
