Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive protocol data units (PDUs) in multiple TTIs (e.g., slots). The wireless communication device may generate, for each TTI of the multiple TTIs, a descriptor that identifies serial numbers (SNs) of PDUs that are received in the TTI. The wireless communication device may aggregate the descriptors for the multiple TTIs into an aggregated descriptor that identifies the SNs of the PDUs across the multiple TTIs. The wireless communication device may process the PDUs received in the multiple TTIs based at least in part on the aggregated descriptor. Numerous other aspects are described.

Abstract: A method of wireless communication by a user equipment (UE) includes receiving a number of uplink grants from a base station. The method further includes estimating a payload size for data to be transmitted from a UE buffer for a number of logical channels. The payload size corresponds to a sum of a number of data bytes to be transmitted and an amount of overhead bytes to be transmitted. The method still further includes determining a subset of the number of uplink grants to use for uplink transmission based on reducing a total padding size associated with transmitting the payload size, for each combination of the number of uplink grants. The method also includes transmitting the data from the UE buffer within a number of transport blocks, to the base station. The number of transport blocks corresponds to the subset of the number of uplink grants.

Abstract: Certain aspects of the present disclosure provide a technique executed by a user equipment (UE) for obtaining a burst of transmission control protocol (TCP) packets conveying packet data convergence protocol (PDCP) protocol data units (PDUs) by an application protocol TCP layer of a communication protocol stack of the UE. The UE may then determine a first number of a first plurality of acknowledge (ACK) tokens to transmit in a first transmission time interval (TTI) based on an amount of data used to ACK the burst of TCP packets. The UE may then transmit the first plurality of ACK tokens in the first TTI and a single ACK token in a second TTI subsequent to the first TTI.

Abstract: In an aspect, while a mobile device is operating in a RRC_Idle State, an RRC_Suspended State, an RLF State and/or an RLF Recovery Procedure State, the mobile device may transmit a connection establishment message to a base station of a plurality of base stations. In an aspect, the connection establishment message includes information that indicates whether the mobile device has information associated with signals transmitted by one or more base stations of the plurality of base stations. The mobile device may initiate transmission of the information associated with the signals to the base station subsequent to establishing a security context for the connection between the mobile device and the base station.

Abstract: Certain aspects of the present disclosure provide techniques for uplink transport protocol acknowledgment shaping and downlink data shaping at a user equipment. A method that may be performed by the UE generally includes determining an allowed number of transport protocol acknowledgments to transmit in a transmission time interval (TTI); and transmitting one or more transport protocol acknowledgments in the TTI based, at least in part, on the determined allowed number of transport protocol acknowledgments. Another method that may be performed by the UE generally includes determining an allowed number of downlink data units to transmit in a TTI; and transmitting one or more data units in the TTI based, at least in part, on the determined allowed number of data units.

Abstract: A UE may receive, via a first communication link that uses a first radio access technology (RAT), information that identifies a threshold associated with a second communication link that uses a second RAT. The UE may monitor one or more communications on the second communication link. The UE may determine whether a parameter associated with the second communication link satisfies the threshold based at least in part on monitoring the one or more communications on the second communication link. The UE may provide a message via the first communication link when the parameter associated with the second communication link satisfies the threshold.

Abstract: Certain aspects of the present disclosure provide techniques for per-flow jumbo maximum transmission unit (MTU) in new radio (NR) systems. A method of wireless communication by a user equipment (UE) is provided. The method generally includes determining a default MTU size to be used for communications in a packet data network (PDN). The method includes determining one or more per-flow MTU sizes, different than the default MTU size, to be used for communications in the PDN. The method includes communicating in the PDN according to the determined per-flow MTU sizes.

Abstract: A method and apparatus for encoding and decoding multiple Acknowledgements (ACKs) during wireless communications are described. In one example, the method and apparatus include receiving multiple ACKs in a queue, the multiple ACKs being scheduled for transmission on a communication channel. The method and apparatus include generating a packet using two or more ACKs of the multiple ACKs that correspond to a first flow, wherein the packet includes Sequence Numbers (SNs) of each of the two or more ACKs, an ACK counter value indicating a number of ACKs in the packet, and a payload corresponding to contents of one of the two or more ACKs. The method and apparatus include transmitting the packet on the communication channel.
