Abstract: A victim user equipment (UE) may experience cross-link interference (CLI) from a physical uplink shared channel (PUSCH) transmission from an aggressor UE or self-interference (SI) from a PUSCH transmission from a transmitter of the victim UE. The present disclosure provides for configuration of measurement resources and a CLI report for mitigation of CLI. A base station may transmit a configuration of the measurement resources including channel state information interference measurement (CSI-IM) resources and a configuration of a CLI report. The CSI-IM resources match PUSCH symbols or demodulation reference signal (DMRS) symbols of an aggressor UE. The victim UE measures a CLI or a SI on the CSI-IM resources. The victim UE reports the CLI or the SI to the base station according to the configuration of the CLI report. The base station may schedule transmissions to mitigate the CLI or the SI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration indicating one or more directions for applying directional digital pre-distortion (DPD) to mitigate interference in a direction to another UE. The UE may transmit a communication to a wireless node based at least in part on applying the directional DPD according to the configuration. Numerous other aspects are described.

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, information indicating that demodulation reference signal (DMRS) time domain bundling is enabled. The UE may determine a time domain bundling configuration based at least in part on the information indicating that the DMRS time domain bundling is enabled. Accordingly, in some aspects, the UE may perform channel estimation based at least in part on DMRSs received in different physical downlink control channel monitoring occasions based at least in part on the time domain bundling configuration. Numerous other aspects are provided.

Abstract: A method of wireless communication, by a transmitting device, includes encoding information packets with an outer code to generate a first outer codeword. The first outer codeword includes information packets in addition to parity packets. The method also includes transmitting, to a receiving device, the information packets and the parity packets of the first outer codeword, according to a sequence. A method of wireless communication by a receiving device, includes receiving packets belonging to a first outer codeword, the packets including information packets and parity packets. The method also includes storing the packets in a buffer; and flushing the packets from the buffer in response to satisfying a condition.

Abstract: This disclosure provides methods, devices and systems for harvesting radio frequency (RF) energy based on an energy harvesting EH indication signal. A transmitting device such as a base station may transmit, to a user equipment (UE), an EH indication signal that indicates a time period when radio frequency (RF) energy is to be available. The UE may receive the EH indication signal and harvest RF energy from the RF signal during the time period. The transmitting device may transmit an RF signal to the UE or another UE during the time period. The UE may receive a wake up indication indicating a second time period to monitor a control channel. The UE may split power between energy harvesting and receiving RF signals during the second time period.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication. A user equipment (UE) may identify a discrete Fourier transform (DFT) matrix including a number of rows and columns based on scheduled physical uplink control channel (PUCCH) resources including a number of symbols in a time domain and a number of sub-carriers in a frequency domain. The UE may select a codepoint from a sequence pool derived from the DFT matrix based on a payload value of uplink control information (UCI) to be transmitted on the PUCCH resources. The UE may transmit the selected codepoint on the scheduled PUCCH resources.
