Abstract: Certain aspects of the present disclosure relate to methods and apparatus for enhanced user equipment (UE) capability exchange for transitioning a connection from a first radio access technology system to a second radio access technology system. An exemplary method performed by a UE includes communicating with a first base station (BS) via a connection of a first radio access technology (RAT), determining, based on the first RAT, to omit a set of capabilities of the UE from capabilities information of the UE regarding a second RAT, transmitting the capabilities information of the UE regarding the second RAT to the first BS via the first RAT, communicating with a second BS via the second RAT according to the capabilities information, and sending an update of the capabilities information of the UE regarding the second RAT via the second RAT.

Abstract: Aspects are provided which allow a UE to trigger initiation of an SR procedure in response to a decrease in an amount of received data or uplink grants following a measurement gap. The UE receives data from a first base station. The UE performs a measurement of a downlink signal from a second base station based on a measurement configuration. The UE transmits a scheduling request in response to a decrease in at least one of an amount of received downlink data or a number of received grants to transmit uplink data after the measurement is performed. As a result, inefficient data stalls caused by erroneous DRX determinations by a base station may be avoided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a first common frequency resource (CFR) configured for multicast downlink communications and associated with a first bandwidth part, and an indication of a second CFR configured for broadcast downlink communications and associated with a second bandwidth part. The UE may determine whether to switch a bandwidth part for receiving downlink communications based at least in part on the indication of the first CFR and the indication of the second CFR. 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 first configuration to perform an uplink communication using a first frequency spectrum band. The UE may receive a second configuration to receive a downlink communication using a second frequency spectrum band. The UE may determine an interference caused by at least one of the first frequency spectrum band or the second frequency spectrum band. The UE may reroute, based at least in part on the determination, the uplink communication to a first uplink path or a second uplink path associated with the first frequency spectrum band. Numerous other aspects are provided.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for terminating HARQ retransmissions. A wireless receiver may determine that a transmission of a first TB based on a first redundancy version is not received from a wireless transmitter. Based on the determination, the wireless receiver may transmit, to the wireless transmitter, a HARQ ACK to terminate one or more HARQ retransmissions associated with the different redundancy versions of the first TB.

Abstract: Wireless communication systems and methods related to Radio Link Control (RLC) status reporting are provided. A wireless communication device receives one or more radio link control (RLC) packet data units (PDUs) of a sequence of RLC PDUs. The wireless communication device determines missing RLC data PDUs in the sequence of RLC PDUs based on the received one or more RLC PDUs. The wireless communication device receives a first uplink (UL) grant. The wireless communication device transmits a first RLC status report including an indication of a first subset of the missing RLC PDUs less than all the missing RLC PDUs, the indication of the first subset of missing PDUs being based on a size of the first UL grant. The wireless communication device modifies a RLC status prohibit timer based on the transmitted first RLC status report indicating less than all the missing RLC PDUs.

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 radio bearer (MRB) in a radio link control (RLC) acknowledged mode; enter an idle state or an inactive state after the MRB has been configured; and maintain the MRB while the UE is in the idle state or the inactive state subject to one or more limitations associated with maintaining the MRB in the idle state or the inactive state. Numerous other aspects are provided.

Abstract: The disclosure provides for a user equipment (UE) handling radio link control (RLC) reset in wireless communications. Various techniques are described wherein RLC reset procedures are associated with various triggering conditions and predetermined time periods at RLC. Delays for initiation and execution of the RLC reset procedures are also described. In an aspect, the UE determines that at least one data unit to be received over a first logical channel is yet to be received by the UE and that there is data traffic over a second logical channel with higher priority than the first logical channel. In another aspect, the UE delays initiation of an RLC reset on a condition that the UE determines that at least one data unit is yet to be received over the first logical channel and that there is data traffic over the second logical channel.
