Abstract: Wireless communications systems and methods related to configuring a search space set for the communication of downlink control information (DCI) are provided. A first wireless communication device communicates, with a second wireless communication device, a search space (SS) configuration, wherein the SS configuration includes a first search space for uplink scheduling and a second search space for downlink scheduling, the second search space being different than the first search space. The first wireless communication device communicates, with the second wireless communication device, a scheduling grant in one of the first search space or the second search space based on the SS configuration and further communicates data based on the scheduling grant.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a dynamic indication of a transmission power difference between a reference signal and a downlink shared channel for a full-duplex zone. The UE may determine channel state information (CSI) based at least in part on the dynamic indication of the transmission power difference between the reference signal and the downlink shared channel for the full-duplex zone. The UE may transmit a CSI report that identifies the CSI. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit feedback to a base station indicating phase values for sub-bands in a bandwidth part (BWP). The base station may use the phase feedback to perform precoding on a set of beams. To support a reduced payload overhead for the feedback, the UE may implement differential phase feedback. For example, the UE may divide the BWP into a number of sub-band groups and may generate, for each sub-band group of each beam, a first set of bits indicating an absolute phase value for a first sub-band of the sub-band group. The UE may additionally generate a second set of bits indicating differential phase values for the other sub-bands of each sub-band group. The UE may report the first and second sets of bits for the beams to the base station for precoding.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform channel state information (CSI) measurements on one or more reference signal transmissions received from a base station. Based on the CSI measurements, the UE may generate a CSI report, and the UE may transmit the CSI report to the base station. In some cases, the generated CSI report may include a first portion and a second portion. The first portion may indicate whether the second portion of the CSI report includes full-band CSI feedback or partial-band CSI feedback. The second portion may provide the CSI feedback for one or more identified sub-bands. In some cases, the second portion may include a sub-band index indicating the identified sub-bands. Additionally or alternatively, the second portion may include a bitmap indicating a correspondence between multiple CSI feedback values and multiple corresponding sub-band indexes.

Abstract: Methods, systems, and devices for wireless communications are described which provide for efficient backhaul communications and identification of resources for cross-link interference (CLI) measurements and reporting. A common resource pool may be configured in which CLI measurements for resources within the resource pool have a common configuration. When providing information indicating resources that are to be measured for CLI, a bitmap that indicates resources within the common resource pool may be provided with CLI measurement configurations corresponding to the common resource pool configuration. Such a bitmap may be communicated via backhaul connections between neighboring base stations when initiating a CLI measurement. Various described techniques also provide for common configuration for CLI measurements, provide for efficient reporting of CLI measurements, and provide for accurate representation of CLI based on measurements at a victim UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first base station (BS) may detect remote interference, with one or more uplink communications on a physical uplink shared channel (PUSCH) associated with the first BS, caused by propagation of one or more reference signal (RS) communications, transmitted by a second BS, out of a coverage area of the second BS and into a coverage area of the first BS due to reflection of the one or more RS communications. The coverage area of the first BS and the coverage area of the second BS are non-overlapping coverage areas. The first BS may adjust, based at least in part on detecting the remote interference, one or more radio resource allocations of the PUSCH associated with the first BS. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described for enabling a network equipment to reduce interference for downlink (DL) transmissions to a first device by determining a transmit precoding matrix indicator (TPMI) for uplink (UL) transmissions transmitted by a second device based on feedback from the first device. The first device may determine a subset of possible TPMIs that the second device may use for UL transmissions for full-duplex communications. The first device may indicate the subset to the network equipment. Based on the subset indicated by the first device, the network equipment may determine a pairing of the first device and the second device for full-duplex communications. Additionally, the network equipment may determine a TPMI for the second device to use in UL transmissions and indicate the TPMI to the second device.
