Abstract: Aspects relate to mechanisms for wireless communication devices to report sub-band (SB) channel state information (SB-CSI). A UE receives a physical downlink shared channel (PDSCH) transmission from a base station. The UE transmits either an acknowledgement (ACK) transmission or a negative acknowledgement (NACK) transmission to the base station in response to a reception of the PDSCH transmission. The UE determines whether to transmit a sub-band (SB) channel state information (SB-CSI) report to the base station based on whether the ACK transmission is transmitted to the base station or whether the NACK transmission is transmitted to the base station.

Abstract: A method of non-coherent wireless communication performed by a wireless communication device includes generating information bits for transmission to another wireless communication device. The method also includes identifying a configuration for a polar code encoder for encoding the information bits. The method further includes encoding a set of the information bits with a polar code encoding operation based on the configuration to generate a codeword, the configuration rendering the polar code encoding operation incapable of generating a codeword that is a bit-flipped counterpart of another codeword that the polar code encoding operation is capable of generating based on the configuration. The method still further includes transmitting the codeword via a wireless channel without a reference signal.

Abstract: Aspects described herein relate to receiving one or more downlink transmissions from a base station, and transmitting, based on comparing one or more parameter values of the one or more downlink transmissions to one or more threshold values, a sounding reference signal (SRS) to the base station over uplink resources. Other aspects relate to receiving, from a user equipment (UE), feedback related to decoding one or more downlink transmissions, wherein the feedback includes an indication that the UE is transmitting a SRS, and receiving, based on the indication, the SRS from the UE over uplink resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may select a precoding matrix of orthogonal beams. The base station may precode a channel state information reference signal (CSI-RS) transmitted to a user equipment (UE) using the precoding matrix of orthogonal beams. The base station may receive, from the UE, one or more reports that indicate one or more beam indices selected from beam indices associated with the precoding matrix of orthogonal beams. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may adjust a transmission parameter, associated with an uplink transmission from the UE, such that a phase for the uplink transmission is continuous across symbols of the uplink transmission. Adjusting the transmission parameter includes at least one of: rate-matching, puncturing, or power scaling one or more of the symbols within the uplink transmission, modifying at least one of a modulation and coding scheme or a power associated with a downlink transmission to the UE, or a combination thereof. The UE may further transmit, to a base station, the uplink transmission based at least in part on adjusting the transmission parameter. Numerous other aspects are provided.

Abstract: The apparatus of wireless communication is a UE and a base station. The UE received a control information indicating a reference signal (RS) mode for a non-coherent transmission of an UCI to the base station. The UE in the RS mode may map an RS according to an RS pattern and the UCI into resource elements assigned for a PUCCH to transmit the UCI and transmit an uplink control signal including the RS and the UCI to the base station over the PUCCH. The UE may determine a RS pattern and puncture the resource elements mapped with the code point of the UCI that corresponds to the RS pattern and map the RS based on the RS pattern. The UE may map the RS based on the RS pattern and map the code point by rate matching around the resource into which the RS is mapped.
