Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently reporting channel state information (CSI) with limited overhead. In one aspect, if a user equipment (UE) is configured to transmit data and CSI to a base station periodically, the UE may transmit the CSI when the UE has data to transmit to the base station. In particular, the UE may transmit data and a CSI report during a transmission opportunity if the UE has data to transmit in the transmission opportunity. Otherwise, the UE may suppress transmission of the CSI report. In another aspect, a UE may be configured to transmit CSI to abase station when downlink channel conditions change. In particular, the UE may request to report CSI to the base station when channel conditions change, and the base station may trigger the UE to report the CSI after receiving the request.

Abstract: A UE may receive DCI from a first TRP scheduling a transmission of a TB from the first TRP and a second TRP. The UE may receive, from the first TRP a first set of CBGs of the TB in a first set of resources. The UE may receive, from the second TRP a second set of CBGs of the TB in a second set of resources that is different than the first set of resources. The first set of CBGs may be received based on a first MCS and the second set of CBGs may be received based on a second MCS. The UE may transmit, in a full-duplex mode, a message to the first TRP. The transmission to the first TRP may overlap in time with the reception from the first TRP. Accordingly, the first MCS may be lower than the second MCS.

Abstract: Data aware precoding techniques are disclosed. A transmitter may apply a precoder function to payload data to obtain a precoded data transmission. The precoder function may include a first portion, e.g., based on a channel measurement, and a second portion, e.g., based on data for transmission. The transmitter may transmit the precoded data transmission. A receiver may receive a precoded data transmission that is precoded based on a channel measurement and based on data comprised in the data transmission. The receiver may decode the precoded data transmission based on the channel measurement and the data comprised in the data transmission.

Abstract: Apparatus, methods, and computer program products for SSB adaptive power transmission are provided. An example method includes performing a measurement of a medium for transmission of an SSB. The example method further includes transmitting, based on the measurement, the SSB at an SSB candidate position from a set of SSB candidate positions, wherein transmitting the SSB comprises transmitting using a first transmission power level if the measurement is within a first range and transmitting using a second transmission power level if the measurement is within a second range, the second transmission power level being lower than the first transmission power level.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a request to apply demodulation reference signal (DMRS) bundling to uplink transmissions. The UE may transmit multiple uplink transmissions. The UE may transmit an indication of whether the UE is able to comply with the request based at least in part on whether the UE is able to maintain phase coherence across the multiple uplink transmissions. Numerous other aspects are provided.

Abstract: A user equipment (UE) determines an occurrence of a triggering event for providing negative acknowledgment (NACK) based feedback for a semi-persistent scheduling (SPS) transmission. The apparatus monitors for the SPS transmission. The apparatus transmits a NACK if the SPS transmission is not successfully received and refrains from sending an ACK if the SPS transmission is successfully received based on the occurrence of the triggering event for providing NACK based feedback. The base station determines an occurrence of a triggering event for a UE to provide NACK based feedback for an SPS transmission. The apparatus transmits the SPS transmission and determines that the UE successfully received the SPS transmission based on an absence of a NACK from the UE for the SPS transmission.

Abstract: Aspects relate to mechanisms for wireless communication devices for tone reservation. A user equipment (UE) receives an indication of one or more peak-reduction tone (PRT) resources for a transmission of one or more signals for a base station. The UE transmits a first signal to the base station on an uplink. The UE transmits a second signal to a relay entity on a sidelink for reception by the base station. The second signal is transmitted on the sidelink utilizing the one or more PRT resources.
