Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration, for a multicast broadcast service (MBS) single frequency network (SFN) area, indicating configuration information for one or more multicast traffic channels. The UE may receive, in accordance with the configuration, a physical downlink control channel (PDCCH) communication scheduling an MBS SFN data communication associated with a multicast traffic channel, of the one or more multicast traffic channels. The UE may receive the MBS SFN data communication via a physical downlink shared channel (PDSCH) that is associated with both SFN communications and unicast communications or that is associated with only MBS SFN communications. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radio bearer may detect, at a packet data convergence protocol (PDCP) layer, expiry of a timer associated with a packet for transmission. The radio bearer may be configured to discard the packet upon expiry of the timer. Accordingly, the radio bearer may re-enqueue, at a modem of the radio bearer or at an application layer of the radio bearer and based at least in part on detecting expiry of the timer, the packet as a new packet for transmission before discarding the packet. Additionally, or alternatively, the radio bearer may retransmit the packet based at least in part on instructions from an application, executed on one or more processors of the radio bearer, that received the packet from the PDCP layer before the packet was discarded. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a trigger for transmitting a buffer status report (BSR). The UE may transmit, to a base station, a long BSR for a single logical channel group (LCG) with data to be transmitted based at least in part on at least one of a determination that a current buffer size for the single LCG is greater than a maximum buffer size indication in a short BSR or a determination that a current achievable uplink throughput using the short BSR is less than a configured uplink throughput. Numerous other aspects are described.

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 registering with a first public land mobile network (PLMN) of a first network operator in response to detection of an interruption event associated with a second PLMN of a second network operator; determining that the interruption event has ended; and taking one or more actions to communicate with the second PLMN in response to the ending of the interruption event, wherein taking the one or more actions to communicate with the second PLMN is based on a constraint associated with access attempts to the second PLMN.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify radio access technology (RAT) state information associated with the UE, the RAT state information including an indication of whether the UE is operating in a steady state or is operating in a transition state. The UE may adapt a codec rate associated with an application of the UE based at least in part on whether the UE is operating in the steady state or is operating in the transition state. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, during a packet data convergence protocol (PDCP) reordering timer period, whether one or more packet transfer criteria are satisfied. The UE may transfer, during the PDCP reordering timer period, one or more packets from a reordering window based at least in part on a determination that the one or more packet transfer criteria are satisfied. Numerous other aspects are provided.

Abstract: The apparatus of wireless communication may include a transmitter connected to a receiver through a split carrier including a first carrier and a second carrier, and the transmitter may be configured to schedule transmission data at PDCP level by splitting the transmission data to first packets and second packets based on a relative scheduling delay between the first carrier and the second carrier, and scheduling the first packets and the second packets on different links based on a scheduling proportion, and transmit the first packets via the first carrier and the second packets via the second carrier. The transmitter may sequentially transmit the transmission data starting at an offset as the second packets to a second RLC level associated with the second carrier, wherein the offset is determined based on the relative scheduling delay.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive downlink data that is associated with triggering a feedback message; transmit, before receiving the feedback message for the downlink data at a component of the user equipment, a scheduling request to request an allocation of a set of resources for transmitting the feedback message; and transmit the feedback message in connection with the set of resources. Numerous other aspects are provided.

Abstract: Aspects of a method, a computer-readable medium, and an apparatus are provided for wireless communication at a base station. The apparatus configures a user equipment (UE) with a first logical channel prioritization (LCP) configuration and a second LCP configuration for a logical channel. The apparatus indicates for the UE to use the first LCP configuration for uplink transmissions on a logical channel based on a first condition. The apparatus indicates for the UE to use the second LCP configuration for the uplink transmissions on the logical channel based on a second condition. The UE transmits uplink transport blocks based on the indicated LCP configuration for the logical channel.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, handling header compression in scenarios with concurrent connections, such as make-before-break (MBB) handover or dual connectivity (DC) scenarios. A method of wireless communication performed by a user equipment (UE) can include concurrently communicating with a first base station (BS) on a connection with the first BS and with a second BS on a connection with the second BS during a handover procedure. The UE maintains a context for a header compression protocol for the connection with the first BS and the connection with the second BS. The concurrently communicating includes using the header compression protocol context for sending one or more packets, receiving one or more packets, or both.
