摘要： 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.

摘要： Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter device may determine a completion of a handover or a radio link failure after transmitting a set of physical data units (PDUs). The transmitter device may retransmit a PDU, of the set of PDUs, after completion of the handover or the radio link failure to enable decompression of the set of PDUs. A receiver device may receive the retransmitted PDU. The receiver device may decompress the set of PDUs based at least in part on receiving the retransmitted PDU. Numerous other aspects are provided.

摘要： 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.

摘要： 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 handling 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.

摘要： Certain aspects of the present disclosure provide techniques and apparatus for quick radio link control (RLC) retransmission on hybrid automatic repeat request (HARQ) failure during tune away. According to certain aspects, a method for wireless communications is provided. The method generally includes performing communications with a base station (BS) using radio components tuned to a first air interface, detecting a tune-away of the radio components from the first air interface to a second air interface while performing the communications, and scheduling one or more packets for retransmission to the BS upon completion of the tune-away, wherein the one or more packets are one or more packets that failed to be transmitted due to the tune-away.
