Abstract: A base station may select an active set of serving cells for a user equipment (UE) from a configured cell set of the UE. The base station may select a cell of the active set of serving cells to perform a primary cell (PCell) function for the UE. The base station may select the cell and transmit an indication of the selected cell to the UE in layer 1 or layer 2 signaling, or the base station may select the cell using a common rule and the UE may select the cell using the common rule. Upon determining the cell, the UE may perform the PCell function with the cell.

Abstract: A user equipment (UE) reports, to a base station, UE duplex communication characteristics. The UE then communicates with the base station in accordance with the reported characteristics. The characteristics can include duplex communication modes supported by the UE. The modes can include receiving and transmitting concurrently with the base station; communicating in a first direction with the base station and concurrently communicating in an opposite direction with a second base station; communicating with the i in a first direction concurrent with the base station communicating in an opposite direction with another UE; and communicating in half duplex (HD) with the base station in HD. The UE can receive, from the base station, a command to communicate in a reported mode. In such cases, communicating, by the UE with the base station, in accordance with the reported duplex communication characteristics includes communicating with the base station in the commanded mode.

Abstract: A base station may identify a configuration of one or more time gap periods associated with FD beam pair quality measurement. The base station may transmit, to the UE, and the UE may receive, from the base station, an indication of the configuration of the one or more time gap periods associated with FD beam pair quality measurement. The UE may perform, during the one or more time gap periods, one or more measurements of a quality of one or more FD beam pairs. Each of the one or more FD beam pairs may include an uplink beam and a downlink beam. The UE may identify at least one failed FD beam pair in the one or more FD beam pairs based on the one or more measurements of the quality of the one or more FD beam pairs and an SI measurement.

Abstract: A user equipment (UE) detects a beam failure for a first beam pair being used for full duplex communication with a base station. The UE indicates the second beam pair for the full duplex communication to the base station to the base station. The UE applies the second beam pair for full duplex communication a period of time after indicating the second beam pair to the base station. The base station receives a beam failure recovery request (BFRQ) from the UE, the BFRQ indicating a beam failure for a first beam pair for full duplex communication at the UE. The base station receives an indication of a second beam pair selected by the UE for the full duplex communication at the UE that the UE will apply a period of time after the indication.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may indicate via control signaling a switching pattern for a bandwidth part (BWP) for communication between a user equipment (UE) and the base station. The switching pattern may include a set of slots associated with a full-duplex communications mode and a set of slots associated with a half-duplex communications mode. The UE and the base station may communicate in the half-duplex communications mode using the BWP, and the UE and the base station may communicate in the full-duplex communications mode using at least one of a first sub-BWP of the BWP for uplink signaling and a second sub-BWP of the BWP for downlink signaling. The base station may configure different resource allocations, operating parameters, and physical uplink control channel resources for the same configured transmissions or receptions for the half-duplex communications mode and the full-duplex communications mode.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a base station establishing full-duplex communications with a first user equipment (UE) and a second UE. The method may include the first UE receiving an interference threshold from the base station, receiving a pathloss reference signal from the second UE, and determining cross-link interference between the first UE and the second UE based on the pathloss reference signal. The method may include the first UE adjusting a transmit power setting of the first UE in accordance with the cross-link interference and transmitting to the base station an uplink metric report, the uplink metric report including an uplink metric of the first UE that is based on the adjusted transmit power setting of the first UE.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications device may select a first set of one or more configured or default beams for full-duplex communications with one or more transmission reception points (TRPs) during one or more full-duplex symbol periods. The first set of one or more default beams may include one or more uplink default beams, one or more downlink default beams, or a pair of uplink and downlink default beams.
