Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine to discard a number of packets from a plurality of packets included in a packet stream. The plurality of packets may be associated with a context. The wireless communication device may determine that the number of packets to discard does not satisfy a threshold associated with the context. The wireless communication device may discard the number of packets. The wireless communication device may transmit the plurality of packets after discarding the number of packets based at least in part on the determination that the number of packets does not satisfy the threshold. Numerous other aspects are provided.

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 wireless communications by a user equipment (UE) capable of establishing a split bearer involving at least primary and secondary radio link control (RLC) entities. The techniques generally include deciding, based on one or more conditions, whether to submit a Packet Data Convergence Protocol (PDCP) protocol data unit (PDU) to the primary RLC entity or the secondary RLC entity according to one or more rules and submitting the PDCP PDU to at least one of the primary or secondary RLC entities in accordance with the decision.

Abstract: Aspects of the present disclosure provide mechanisms for fast hyper frame number (HFN) resynchronization of Packet Data Convergence Protocol (PDCP) Protocol Data Units (PDUs). A wireless communication device (e.g., a PDCP entity at a wireless communication device) can calculate a current PDCP count of a current PDCP PDU of a plurality of PDCP PDUs received from a radio link control (RLC) sublayer based on a PDCP sequence number (SN) of the current PDCP PDU and an HFN of a first missing PDCP PDU after a successfully received PDCP PDU. The PDCP count may be calculated using the HFN of the first missing PDCP PDU in response to a gap between the PDCP count of the first missing PDCP PDU and the actual PDCP count of the current PDCP PDU being greater than a PDCP window size.

Abstract: Apparatus, methods, and computer-readable media for facilitating prioritizing PDCP retransmission and/or control information in dual connectivity scenarios are disclosed herein. An example method for wireless communication at a first network node includes receiving PDUs for transmitting to a second network node while operating in a dual connectivity mode associated with a first RLC leg and at least a second RLC leg, the PDUs associated with at least one of control information or retransmission data. The example method also includes transmitting first scheduling information via the first RLC leg and transmitting second scheduling information via the second RLC leg based on the PDUs being associated with at least one of the control information or the retransmission data. The example first network node may include a UE or a base station.

Abstract: A method of wireless communication, by a user equipment (UE), includes setting up a secondary cell group (SCG) with a second radio access technology (RAT) that differs from a first RAT associated with a master cell group (MCG). The method also includes communicating wirelessly via the secondary cell group and the master cell group. The method further includes predicting a radio link failure (RLF) for the secondary cell group based on multiple inputs to a machine learning model. The method still further includes routing data transmission from the secondary cell group to the master cell group, after predicting the SCG RLF.
