Abstract: A receiving device re-establishing a packet data convergence protocol (PDCP) entity. The receiving device resets a robust header compression (ROHC) context. The receiving device receives packet retransmissions having header compression based on the ROHC. The receiving device performs decompression of the packet retransmissions. The receiving device discards duplicate packets after performing the decompression of the packet retransmissions.

Abstract: A configuration to adjust expiration of a PDCP reorder timer based on scheduler variations in dual connectivity. The apparatus receives, from a base station, a plurality of data packets. The plurality of data packets received from a first path and a second path. The apparatus detects at least one packet of the plurality of data packets at a PDCP is dropped based on an OOW. The apparatus determines a scheduling gap between the first path and the second path. The apparatus determines a timing relationship between the UE, the first path, and the second path. The apparatus determines consecutive sequence numbers associated with packets corresponding to the frame numbering sequence of the first path and the frame numbering sequence of the second path and a respective associated time. The apparatus adjusts a reorder timer based on the scheduling gap between the first path and the second path.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a transmission control protocol (TCP) packet loss based at least in part on a packet data convergence protocol (PDCP) payload of a packet. The UE may transmit a plurality of retransmission requests of the packet based at least in part on the detection of the TCP packet loss for the packet. Numerous other aspects are described.

Abstract: Some aspects of the present disclosure disclose methods and systems for managing transmission control protocol (TCP) acknowledgements (ACK) transmissions from a host or application processor to a modem of a user equipment. The UE may detect availability of buffer space in a memory buffer of a modem of the UE. Further, the UE may also detect that a host processor of the UE lacks credit sufficient for transmitting data from the host processor to the modem. The UE may then generate and transmit to the host processor a data flow control (DFC) command including credit sufficient for the host processor to transmit at least a portion of the data to the modem. In some instances, in response to the transmission of the DFC command, the at least the portion of the data may be received at the modem from the host processor.

Abstract: Methods executed by a processor element for providing data packets from a modem to an application processor in a computing device are disclosed. Exemplary implementations may reorder packets received by the modem from a plurality of parallel flows so as to provide to the application processor batches of packets from individual flows within the plurality of parallel flows.

Abstract: A user equipment (UE) may be configured with one or more queues at which packets are accumulated before being transferred between at least one higher layer and at least one lower layer. The UE may release packets from the one or more queues based on at least one set of parameters. The UE may determine one or more radio conditions associated with at least one traffic flow between the UE and a network. The UE may configure a set of parameters associated with transfer of packets for the at least one traffic flow between a lower layer of the UE and a higher layer of the UE based on the one or more radio conditions. The UE may communicate a first set of packets with the network for the at least one traffic flow based on the set of parameters.

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: Aspects of the present disclosure describe transmitting data in wireless communications. A set of packets for transmission in a defined sequence can be received where the set of packets includes two or more packets. It can be detected that a packet, of the set of packets, is a prioritized packet type. The packet can be prioritized for transmission ahead of its order in the defined sequence based on the detection of the prioritized packet type. The packet can be transmitted ahead of its order in the defined sequence to an access point.
