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: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for handling multi-UE scheduling conflicts. A first UE may receive group common DCI that schedules each of a plurality of UEs including the first UE for an uplink transmission or a downlink reception. The group common DCI may include per UE priority indications for each of the plurality of UEs. The first UE may resolve a conflict between first resources scheduled for the first UE that overlap in time with second resources scheduled for a second UE of the plurality of UEs. Resolving the conflict may include reducing self-interference associated with a full-duplex communication based on the per UE priority indications included in the group common DCI.

Abstract: This disclosure provides systems, methods, and devices that support subband full duplex configuration for wireless communication. Semi-static configuration of one or more downlink subbands, one or more uplink subbands, and one or more guard bands may be implemented via RRC signaling configured for subband full duplex communication. The RRC signaling may include subband frequency configuration pattern information and subband symbol and slot time configuration pattern information. Dynamic configuration of one or more downlink subbands, one or more uplink subbands, and one or more guard bands may be implemented by RRC signaling in combination with MAC-CE and/or DCI signaling. The RRC signaling may preconfigure wireless communications devices with a plurality of subband frequency configuration patterns and a plurality of subband symbol and slot time configuration patterns. The MAC-CE and/or DCI signaling may select and/or activate one or more subband frequency configuration patterns. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling identifying, for multiple beams, a set of quantized values for beam measurement reporting. The UE may receive a set of reference signals and each reference signal may be associated with a beam of the multiple beams. The UE may transmit a report indicating a set of power values that are based on the set of quantized values and the set of reference signals. Each power value of the set of power values may be associated with a respective beam of the multiple beams. The control signaling may also indicate a set of rules for vector-based beam management reporting for the multiple beams. The report may include a vector report and may indicate the set of power values based on the set of rules and the set of reference signals.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) that schedules an aperiodic channel state information reference signal (CSI-RS) report. The UE may determine, based at least in part on the DCI, a time duration between an end of the DCI and a start of a communication on a physical uplink shared channel that includes the aperiodic CSI-RS report. The time duration may be based at least in part on an aperiodic CSI beam switch latency threshold. The UE may generate the aperiodic CSI-RS report based at least in part on a CSI-RS measurement. The UE may transmit the aperiodic CSI-RS report based at least in part on the DCI associated with the time duration. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. A communication device, for example, a user equipment (UE) may select a default beam to use for downlink communication while operating in a full duplex mode. The UE may receive from another communication device, for example, a base station control signaling indicating the default beam for the UE to use for the downlink communication. A default beam (which may also be referred to as a full duplex beam) may be a default downlink beam or a default uplink beam. In some examples, the UE may select a default beam pair to use for downlink communication and uplink communication while operating in the full duplex mode. A default beam pair (which may also be referred to as a full duplex beam pair) may include both a default downlink beam and a default uplink beam.

The device can determine to use the default beam information for configuring the beam for a data channel communication based on determining explicit beam information is not configured. In addition, the device can transmit, based on determining to use the default beam information, the data channel communication based on the beam configured using the default beam information.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may experience multiple types of self-interference (SI), perform interference measurement procedures, and may identify interference mitigation procedures. The UE may identify a configuration for performing SI measurements (SIMs), where the configuration indicates a first transmission power associated with a first transmission and a second transmission power associated with a second transmission, where the second transmission power is higher than the first transmission power. The UE may transmit the first transmission at the first transmission power and the second transmission at the second transmission power, where the first transmission is associated with a first repetition frequency and the second transmission is associated with a second repetition frequency. The UE may measure SI based on transmitting the first transmission and the second transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a message to a transmission reception point (TRP) in a multi-TRP network that indicates a capability of the UE to support a communication scheme (e.g., a spatial division multiplexing (SDM) scheme, a single frequency network (SFN) scheme, a combined SDM and SFN scheme, or the like). The UE may receive a configuration that indicates parameters common to both the SDM scheme and the SFN scheme. The TRP may transmit an indication of an SDM scheme, an SFN scheme, a combined SDM and SFN scheme, or the like to the UE for communications between the UE and one or more TRPs. The UE may communicate with the one or more TRPs based on the communication scheme indicated by the TRP.

Abstract: Certain aspects of the subject matter described in this disclosure can be implemented in a method for wireless communication by a user equipment (UE). The method generally includes receiving, from a network entity, signaling that schedules an uplink or downlink transmission on resources that overlap with a time gap for switching from a first set of frequency resources to a second set of frequency resources; and taking an action to process the uplink or downlink transmission so that the uplink or downlink transmission does not overlap with the time gap.
