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, a configuration message that is associated with a full duplex transmission mode. The configuration message includes at least one indicator of a resource for channel measurement, where the at least one indicator of the resource for channel measurement is associated with a plurality of resources for interference measurements that include at least one resource for self-interference measurement. Additionally, or alternatively, the configuration message includes at least one indicator of a format for a sub-band report, where the format indicates that the sub-band report is to include at least one of reference signal received power, signal-to-interference-and-noise ratio, or a combination thereof. The UE may transmit, to the base station, at least one report based at least in part on the configuration message. Numerous other aspects are described.

Abstract: Aspects of the disclosure relate to inter-band carrier aggregation. A user equipment (UE), for example, may obtain a measured configured maximum UE output power (PUMAX) and prioritize aspects of UE transmissions that contribute to PUMAX. Prioritization may be based, for example, on band priority, channel priority, service priority, or any combination thereof. The power levels related to the prioritized features may be changed by changing a power management maximum power reduction (P-MPR) of each feature associated with the transmission according to the prioritized order of the features. The UE may determine if an electromagnetic power density exposure level of the UE is at or below a predetermined maximum permissible exposure (MPE) level. The UE may continue to reduce the transmitter output power if the electromagnetic power density exposure level is greater than the predetermined MPE level. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods and devices for discontinuous reception signaling for wireless communications systems are described. A base station may determine a semi-persistent scheduling (SPS) configuration and a discontinuous reception configuration (DRX) associated with the semi-persistent scheduling (SPS) configuration for a user equipment (UE). The base station may transmit the SPS configuration to the UE. The SPS configuration may indicate one or more DRX parameters for the DRX configuration. A UE may receive the semi-persistent scheduling configuration from the base station. The UE may identify one or more DRX parameters for the discontinuous reception configuration based on the SPS configuration. The UE may monitor a downlink control channel in accordance with the DRX configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity, such as a base station, may receive, from a first network entity, a broadcast indicating a downlink control channel transmission pattern associated with the first network entity. The network entity may monitor a plurality of receive beams for a plurality of downlink control channel transmissions from the first network entity according to the downlink control channel transmission pattern and may select a communication beam according to one or more cross-link interference (CLI) measurements associated with one or more of the plurality of receive beams in accordance with the monitoring. The network entity may communicate with a user equipment using the selected communication beam and a first set of resources that at least partially overlap in time and frequency with a scheduled communication at the first network entity. The network entity may experience or may cause the measured CLI.

Abstract: In multi-beam communication, the UE may assist in the scheduling of beams utilized during the multi-beam communication by improving the manner in which the quality of the beam is reported to the network. The apparatus may measure a signal received from a base station on at least one beam. The apparatus may detect a triggering event for providing CSI for the at least one beam. The apparatus may transmit an uplink transmission comprising a CSI report in response to detecting the triggering event. The apparatus may receive an uplink request from a UE for providing CSI for at least one beam. The apparatus may transmit an indication scheduling a CSI report in response to the uplink request. The apparatus may receive an uplink transmission from the UE comprising the CSI report for the at least one beam.

Abstract: A UE receives a configuration for one or more downlink reference signal or downlink channel from a base station and receives an indication of one or more time and frequency resources for full-duplex communication at the base station. The UE skips reception of the one or more downlink reference signal or downlink channel based at least in part on the indication of the one or more time and frequency resources for the full-duplex communication at the base station. A UE receives, from a base station, an allocation of uplink resources for an uplink transmission and receives an indication of one or more time and frequency resources for full-duplex communication at the base station. The UE transmits the uplink transmission to avoid the one or more time and frequency resources for the full-duplex communication at the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to transmit, to a base station, capability signaling indicating a quantity of sounding reference signal (SRS) ports supported by an antenna panel of a set of antenna panels at the UE. The UE may receive control signaling indicating an SRS configuration including multiple SRS sets, multiple SRS resource lists, or both, where the multiple SRS sets or multiple SRS resource lists are associated with respective quantities of supported SRS ports. The UE may then transmit, to the base station and based on the control signaling, a measurement report indicating a quantity of sounding SRS, and transmit an SRS to the base station in accordance with the SRS configuration and the indicated quantity of SRS ports.
