Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing signaling for indicating a scheduled full duplex (FD) uplink (UL) and downlink (DL) traffic scheduling combination for differentiation of FD traffic. In some aspects, a BS may transmit a downlink control information (DCI) message that includes an indication of the scheduled FD UL and DL traffic scheduling combination. The FD UL and DL traffic scheduling combination may identify scheduled UL and DL transmissions for FD mode operation. The UE may receive the DCI message and identify the scheduled FD UL and DL traffic scheduling combination. In some aspects, the BS may provide a DCI message to the UE that indicates whether a DL transmission is being scheduled that at least partially overlaps with a scheduled UL transmission. The UE may initiate a power save mode based on the received DCI message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device (WCD) may transmit, to a second WCD, information for selecting transmission or reception directions for a first beam and a second beam for communications between the first WCD and the second WCD using a full duplex operation. The WCD may receive an indication to use, for the full duplex operation of the first WCD, the first beam to receive communications and the second beam to transmit communications. 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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit control signaling indicating a capability of the UE for supporting a first duplex mode and indicating a mode switching latency of the UE for switching between the first duplex mode and a second duplex mode. In some cases, the UE may transmit an indication of a set of supported full-duplex channel combinations, where each channel combination of the set of supported full-duplex channel combinations may include an uplink channel and a downlink channel. In some cases, the UE may transmit an indication of a duration for which the capability of the UE for supporting the first duplex mode is applicable. The UE may receive scheduling information based on the capability of the UE for supporting the first duplex mode and the mode switching latency, and communicate with a base station based on the scheduling information.

Abstract: Apparatus, methods, and computer-readable media for facilitating duplex mode per uplink control channel resource are disclosed herein. An example method for wireless communication at a user equipment includes receiving a physical uplink control channel (PUCCH) resource configuration from a base station, the PUCCH resource configuration indicating an uplink beam for transmitting an uplink transmission. The example method also includes identifying a downlink beam paired with the uplink beam for transmitting the uplink transmission, the paired downlink beam for full-duplex reception of a downlink transmission from the base station that overlaps in time with transmission of the uplink transmission. Additionally, the example method includes performing full-duplex communication with the base station by transmitting the uplink transmission using the uplink beam while receiving the downlink transmission using the paired downlink beam.

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: The present disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for an autonomous fallback for a full-duplex beam pair. In a first aspect, a first wireless device may determine an occurrence of a performance trigger for a current beam pair for full-duplex communication at the first wireless device and use a fallback full-duplex beam pair in response to determining the occurrence of the performance trigger. In a second aspect, the first wireless device may receive an indication from a second wireless device of an occurrence of the performance trigger for the current beam pair for full-duplex communication and using the fallback full-duplex beam pair for communication with the second wireless device in response to receiving the indication.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, prior to a first on duration of a discontinuous reception cycle, a first indication that the UE is to remain in an inactive state of the discontinuous reception cycle during the first on duration. The UE may receive, prior to a second on duration of the discontinuous reception cycle, a second indication that the UE is to transition to an active state during the second on duration, wherein the second indication indicates, based at least in part on the first indication indicating that the UE is to remain in the inactive state during the first on duration, and one or more physical cell identifiers for the UE to communicate with while in the active state. The UE may identify the one or more physical cell identifiers indicated in the second indication.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may store configurations for candidate physical cell identifiers (PCIs) that the UE may select from for inter-cell mobility. A base station or a UE or both may identify a first configuration indicating a number of configured PCIs for inter-cell mobility operations. The base station or the UE or both may identify a second configuration indicating a number of selected PCIs for inter-cell mobility operations. In some cases, the selected PCIs may be a subset of the configured PCIs. Identifying the number of configured PCIs and the number of selected PCIs by the base station and UE may be based on a capability report configured by the UE. The UE and the base station may perform an inter-cell mobility operation based on stored cell configurations associated with the configured PCIs and the selected PCIs.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive a message scheduling a first resource for a downlink communication between a base station and the first UE, the first resource overlapping with a second resource for a random access channel (RACH) occasion (RO) for use by one or more second UEs. The first UE may receive the downlink communication over the first resource based on receiving the message, where the first resource is full-duplexed with the second resource of the RO and may transmit, over a third resource, an indication of cross link interference between a RACH message transmitted over the second resource and the downlink communication. The first UE may receive a second downlink communication over a fourth resource based at least in part on transmitting the indication.
