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 second wireless device may transmit, to a first wireless device, a feedback message indicative of a transition from a first compression state to a second compression state. The first wireless device may transition, based on a state change indication corresponding to the feedback message, from the first compression state to the second compression state. The first wireless device may transmit, to the second wireless device based on the transition from the first compression state to the second compression state, one or more first data packets that are previously compressed based on the first compression state or one or more second data packets that are uncompressed or recompressed based on the second compression state. The one or more second data packets being associated with the one or more first data packets.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for improving buffer size setting for one or more buffer status reports, such as one or more extended buffer status reports (eBSRs) in a wireless communication system. According to certain aspects, a method is provided herein for wireless communications performed by a user equipment (UE). The method generally includes determining a first amount of data stored in a buffer at the UE; and if the first amount of the data satisfies (e.g., is equal to or greater than) a threshold, sending a first BSR indicating a second amount of buffered data at the UE greater than the first amount. As a result, the UE may be scheduled by the base station for a greater amount uplink resources for transmitting the buffered data.

Abstract: In wireless communication, uplink communication by a wireless communication system user equipment may include providing data packets by a data source in the user equipment, detecting a pattern relating to uplink transmission of the plurality of data packets, and scheduling transmission of the plurality of data packets by the user equipment. One or more aspects of scheduling transmission of the plurality of data packets may be based on the detected pattern.

Abstract: Various aspects of the disclosure relate to techniques for handling out-of-order grants. For example, upon detection of an out-of-order grant, the best scheduling policy for handing the out-of-order grants may be selected based on at least one traffic condition. In some aspects, a scheduling policy may involve canceling and regenerating out-of-order grants. In some aspects, a scheduling policy may involve reordering data units. In some aspects, a scheduling policy may involve designating a reorder time window.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications. In some aspects, a method, apparatus, system, computer program product, non-transitory computer-readable medium, user equipment, transmitter device, and wireless communication device are presented for unidirectional robust header compression (RoHC). The transmitter device may identify a system resource condition of at least one of the transmitter device or a receiver device of one or more data units, configure robust header compression in a single direction for wireless communication of the one or more data units between the transmitter device and the receiver device, and/or process the data units based at least in part on configuring the robust header compression. Numerous other aspects are provided.

Abstract: Aspects described herein relate to wireless communications. Protocol data units (PDUs) can be received at a network layer from one or more transmitting nodes using a link associated with each respective transmitting node. One or more missing PDUs can be detected based, at least in part, on sequence numbers of the received PDUs. A timer can be started based on the detection of the one or more missing PDUs. In response to expiration of the timer, and without receiving the one or more missing PDUs before the expiration of the timer, a lower network layer can be notified that the one or more missing PDUs are received to prevent attempted transmitting/retransmitting or other processing of the one or more missing PDUs.

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: A wireless device with dual connectivity may transmit split bearer traffic including a plurality of compressed data packets respectively to a first RLC entity of a first base station and a second RLC entity of a second base station and measure BLERs of the transmitted split bearer traffic. Based on the measured BLERs of the transmitted split bearer traffic, the wireless device may transmit uncompressed data packets to one or more of the first RLC entity or the second RLC entity. The wireless device may also reset a context memory and transmit the uncompressed data packets to the first RLC entity and the second RLC entity. A base station with dual connectivity may configure an LTE RLC entity with an RLC out-of-order delivery to deliver the received compressed data packets to an NR-PDCP entity without reordering the compressed data packets at the LTE RLC entity.

Abstract: Systems, methods, and computing platforms for context identifier allocation for data packet header compression are provided. Exemplary implementations may: obtain a first packet of a stream to be sent using a header compression protocol; determine a context identifier (CID) to associate with the stream based, at least in part, on a packet type of the first packet; generate a compressed header for the first packet according to the header compression protocol and based on the determined CID; and transmit the first packet with the compressed header.
