Abstract: Aspects directed towards Quality of Service (QoS) flow remapping are disclosed. In an example, upon detecting a mapping reconfiguration of a first QoS flow from a first data radio bearer (DRB) to another DRB, a Service Data Adaptation Protocol (SDAP) control protocol data unit (PDU) is generated indicating that a final SDAP data PDU associated with the first QoS flow has been transmitted on the first DRB. The SDAP control PDU is then transmitted via the first DRB. In another example, upon detecting a mapping reconfiguration of a first QoS flow from a first DRB to another DRB, an end marker parameter is set in an SDAP header of a first SDAP data PDU received from an upper layer after the mapping reconfiguration indicating that the first SDAP data PDU is a final SDAP data PDU associated with the first QoS flow transmitted on the first DRB.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a prioritization rule that indicates a relative priority for different uplink communications included in a group of uplink communications, wherein the group of uplink communications includes at least a first uplink communication and a second uplink communication to be transmitted by the UE using time-division multiplexing during a make-before-break handover procedure. The UE may transmit, based at least in part on the prioritization rule, the first uplink communication to a target base station and the second uplink communication to a source base station using time-division multiplexing during the make-before-break handover procedure. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first sidelink signal indicating a set of resources that are reserved at the UE for sidelink communications. The UE may perform multiple listen-before-talk (LBT) procedures using respective consecutive slots of the set of resources. The UE may transmit another sidelink signal using a portion of the set of resources following the multiple LBT procedures. The UE may release a remaining portion of the set of resources after transmitting the second sidelink signal. Another UE may receive the first sidelink signal including the indication of the set of resources. The other UE may detect the remaining portion of the set of resources that may be available for the other UE to use for first sidelink communications based on overbooking at the UE.

Abstract: Wireless communications systems and methods related to mobility with consideration for network slicing are provided. In one embodiment, a user equipment (UE) transmits in a first cell frequency of a network, a request for a network slice of the network that is not provided by the first cell frequency. The UE receives, in response to the request, an information for communicating in a second cell frequency of the network that provides the requested network slice. In one embodiment, a core network entity receives, from a network entity operating over a first cell frequency of a network, a request to provide a network slice of the network to a UE, the network slice not provided by the first cell frequency. The core network entity transmits, to the BS, information associated with a second cell frequency of the network providing the network slice.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) (e.g., Tx UE) may transmit or receive a first control message indicating a sidelink beam measurement configuration for performing a sidelink beam sweep procedure using a set of transmit beams. The first UE may select a subset of transmit beams from the set of transmit beams for the sidelink beam sweep procedure based on one or more parameters associated with the sidelink beam measurement configuration. The first UE may then transmit, to a second UE (e.g., Rx UE) during the sidelink beam sweep procedure, a set of sidelink reference signals using respective transmit beams of the subset of transmit beams.

Abstract: Wireless communications systems and methods related to discontinuous reception (DRX) extended-on operations and dynamic transmission patterns in sidelink are provided. A first user equipment (UE) determines a transmission pattern for a first sidelink based on an extended DRX on-duration associated with a second sidelink different from the first sidelink, wherein the first sidelink is between the first UE and a second UE, and wherein the second sidelink is between the second UE and a third UE. The first UE transmits, to the second UE over the first sidelink during the extended DRX on-duration based on the transmission pattern, a communication signal.

Abstract: Wireless communication techniques for utilizing beam-specific RSSI and CO in NR-U wireless communication are discussed. A UE may receive from a base station a first set of one or more RSSI measurement configuration parameters associated with a first reception beam as well as a second set of one or more RSSI measurement configuration parameters associated with a second reception beam. The second reception beam may be different than the first reception beam. The UE may transmit a report including at least one of a first indication of one or more RSSI measurements performed using the first reception beam based, at least in part, on the first set of one or more RSSI measurement configuration parameters or a second indication of one or more other RSSI measurements performed using the second reception beam based, at least in part, on the second set of one or more RSSI measurement configuration parameters.
