Abstract: The present disclosure provides systems, methods, and apparatuses for maintaining continuity of a buffer status report (BSR) from a user equipment (UE) when the UE is handed over between base stations. In one aspect, a base station or a component thereof may be configured to allocate a set of resources for transmission by a UE. The set of resources may have a capacity that is insufficient for an amount of data indicated by a BSR from the UE. The base station or component thereof may be further configured to transmit, to another base station in association with handover of the UE, an indication that the capacity of the set of resources is insufficient for the amount of the data indicated by the BSR.

Abstract: A delta configuration is signaled for handover of a wireless communication device (e.g., a user equipment, UE) from a first form of connectivity to a second form of connectivity. For example, a UE with master cell group (MCG) connectivity may be handed-over to multiple radio access technology-dual connectivity (MR-DC). In some examples, a UE with standalone (SA) connectivity may be handed-over to non-standalone (NSA) connectivity (e.g., dual connectivity). In conjunction with this handover the UE may be signaled as to whether the UE is to reuse a configuration from the first connectivity mode during the second connectivity mode.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to procedures for supporting conditional new radio (NR) secondary node (SN) addition and change by using conditional handover (CHO) procedures. A method that may be performed by a user equipment (UE) includes receiving, from a master node (MN), configuration information, identifying a set of candidate cells for a conditional addition or change of a SN for a the UE based on execution criteria, detecting the execution criteria is met for one of the candidate cells, and taking action to add or change to the candidate cell as an SN based on the detection.

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 or broadcast radio bearer (MRB) in a radio link control (RLC) acknowledged mode (AM). The UE may determine an adjustment of an RLC AM transmission window of a base station. The RLC AM transmission window may be associated with retransmission of RLC packets associated with the MRB. The UE may synchronize an RLC AM reception window of the UE with the RLC AM transmission window based at least in part on determining the adjustment of the RLC AM transmission window of the base station. The RLC AM reception window may be associated with reassembly of RLC packets associated with the MRB. 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 receive a configuration for a shared physical downlink shared channel (PDSCH). The UE may receive a first communication via the shared PDSCH and a first bearer based at least in part on the configuration, the first communication being one of a unicast communication or a multicast/broadcast communication. The UE may receive a second communication via the shared PDSCH and the first bearer or a second bearer based at least in part on the configuration, the second communication being the other of the unicast communication or the multicast/broadcast communication. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may receive an indication of a traffic pattern for application traffic. The BS may determine, based at least in part on one or more measurements associated with the traffic pattern, one or more parameters for at least one of a discontinuous reception (DRX) configuration for the application traffic, or a semipersistent scheduling (SPS) configuration for the application traffic. The BS may transmit, to a user equipment (UE) that is to receive the application traffic, an indication of the at least one of the DRX configuration or the SPS configuration. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for remote interference determination at a first base station based on assistance from one or more neighboring base stations of the first base station. Certain aspects provide a method for wireless communication by a first base station (BS). The method includes receiving from a second BS neighboring the first BS an uplink interference report request. The method further includes transmitting to the second BS an uplink interference report in response to the uplink interference report request, the uplink interference report comprising information indicative of uplink interference caused by one or more user equipments communicating on an uplink with the first BS.
