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: Certain aspects of the present disclosure provide techniques for implementing reflective quality of service (RQoS) in wireless communication systems. A method for implementing RQoS that may be performed by a user equipment (UE) generally includes receiving a plurality of downlink user data packets from a first base station (BS), determining at least one reflective quality of service (RQoS) mapping rule for one or more uplink packet transmissions based on a subset of the plurality of downlink user data packets, filtering the plurality of downlink user data packets based on the at least one RQoS mapping rule, and forwarding the plurality of downlink user data packets to a corresponding application entity of the UE based on the filtering.

Abstract: Wireless communications systems and methods related to uplink buffer management are provided. In some aspects, a user equipment receives a synchronization acknowledgment message destined for a device tethered to the user equipment and transmitted by an application server at a network to which the user equipment is connected. In some aspects, the synchronization acknowledgment message includes an application server receiver window size indicating available buffer space in a receive buffer of the application server. The user equipment can modify the application server receiver window size in the received synchronization acknowledgment message prior to transmitting the received synchronization acknowledgment to the tethered device.

Abstract: This disclosure provides systems, methods and apparatuses for using a media access control (MAC) control element (CE) for dynamic RLC entities selection. In one aspect, a base station (BS) may generate and transmit the control message to a user equipment (UE) to identify active radio link control (RLC) entities, a primary RLC entity, or other parameters relating to packet data convergence protocol (PDCP) duplication-based communication. In this case, the UE may use the control message to select an RLC entity and may transmit protocol data units (PDUs) to the BS using a data radio bearer (DRB) and the selected RLC entity.

Abstract: Embodiments include methods for managing a reordering timer performed by a processor of a wireless device. The processor may receive packets from a communication network and store the packets in a memory buffer of the wireless device. The processor may detect one or more conditions that affect an amount of time required to reorder or reassemble at least some of the packets received from the communication network. The processor may determine a timer adjustment based on the detected one or more conditions. The processor may adjust a timer with the determined timer adjustment. The processor may deliver one or more packets from the memory buffer in response to expiration of the adjusted timer.

Abstract: Aspects described herein relate to POLL timer enhancement in fifth generation new radio (5G NR). In an example, the aspects may include determining whether a count of packet data unit (PDU) without POLL associated with a current PDU sequence satisfies a threshold for maximum PDUs without POLL; determining whether a total transmission queue memory exceeds an uplink transmission queue memory threshold; generating a POLL bit based on a determination that the PDU without POLL count associated with the current PDU without POLL in-sequence satisfies the threshold for maximum PDUs without POLL and the total transmission queue memory exceeds the threshold for uplink transmission queue memory; and transmitting, to a network entity, the current PDU with the POLL bit.

Abstract: A user equipment (UE) may utilize multiple radio link control (RLC) entities to duplicate packet data convergence protocol (PDCP) packets for improved reception. The UE may receive a configuration for dual connectivity with a master cell group and with a secondary cell group, wherein the configuration identifies a plurality of configured RLC entities, each RLC entity being associated with one of the master cell group or the secondary cell group. The UE may receive, at the UE, an indication of an activation status for each of at least a first subset of the configured RLC entities from one cell group of the master cell group or the secondary cell group. The UE may set the activation status of each of the first subset of the configured RLC entities that are associated with the one cell group from which the indication is received based on the indication.
