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: Certain aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for preparing data for transmission from a user equipment in a wireless communication system. In some embodiments, a method may limit memory access starts during a time interval to ensure that all memory access operations are completed with a transmission time interval.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to enhanced compression formats for data compression (e.g., uplink data compression (UDC)). A method is provided for wireless communications. The method generally includes determining one or more blocks of data in a current packet matching one or more blocks of data in one or more portions of one or more previous packets stored in a memory, compressing at least a portion of the current packet based on an enhanced compression format having reduced metadata relative to another compression format to indicate one or more of the matching blocks of data, and transmitting the compressed current packet. Numerous other aspects are provided.

Abstract: Apparatus, methods, and computer-readable media for facilitating network slice based reselection using machine learning are disclosed herein. An example method for wireless communication at a UE includes predicting a next active PDU session of two or more PDU sessions based on next connection setup times for each PDU session. The next connection setup times may be estimated based on connection setup events occurring over a period. The example method also includes selecting a frequency channel to camp on based on the next active PDU session.

Abstract: Methods, systems, and devices for wireless communications are disclosed by the present application. A request to establish a call using a first connection may be received, the first connection using a first radio access technology to communicate with a radio access network. During execution of a procedure to establish the call, a command to handover communications from the first connection to a second connection that uses a second radio access technology to communicate with the radio access network may be received. The second connection may be established in response to the command, and a message indicating that the request to establish the call was successfully received may be transmitted over the second connection. Also, a message indicating that an alert of the call is being issued may be transmitted over the second connection.

Abstract: Certain aspects of the present disclosure provide techniques for packet buffering. A method that may be performed by a receiving node includes dynamically determining one or more time durations to buffer packets. The one or more time durations can be different than a time duration of a configured timer for buffering the packets. The receiving node may input one or more parameters to a machine learning algorithm and obtain, as output of the machine learning algorithm based on the input one or more parameters, one or more time durations to buffer packets. The receiving node buffers packets for the determined one or more time durations. The receiving node may use machine learning to dynamically determine the one or more time durations to buffer packet. The buffering may be at a radio link control (RLC) reassembling buffer and/or a packet data convergence protocol (PDCP) buffer.

Abstract: Certain aspects of the present disclosure provide techniques for dynamically determining an uplink data split threshold for communicating using one or more radio link control (RLC) entities of a split bearer configuration. A method that may be performed by a user equipment (UE) includes inputting a first set of parameters to a machine learning algorithm, obtaining, as an output of the machine learning algorithm based at least in part on the inputted first set of parameters, a value for a data split threshold, and transmitting the data using at least one of a first RLC entity or the second RLC entity based on the value for the data split threshold and the amount of data the apparatus has to transmit

Abstract: Techniques and apparatus for implementing a radio link control (RLC) layer and/or packet data convergence protocol (PDCP) layer window advance with holes (e.g., one or more missing packets) are provided. One technique includes generating a sequence of packets for transmission to an apparatus. A determination of whether to request the apparatus to at least temporarily ignore missing packets from the sequence is made based on one or more criteria. A message with an indication of the determination is transmitted to the apparatus. The apparatus may receive the sequence of packets, detect missing packets in the sequence, and process the sequence of packets in accordance with the indication in the received message.
