Abstract: Certain aspects of the present disclosure provide techniques for avoiding out of order uplink data reception upon data radio bearer (DRB) release or quality of service (QoS) flow addition. An exemplary method that may be performed by a user equipment (UE), includes obtaining an indication that a first data radio bearer (DRB) is released or handed over to a second DRB, wherein a first mapping maps a first quality of service (QoS) flow to the first DRB; obtaining a second mapping that maps the first QoS flow to a second DRB; editing service data adaptation protocol (SDAP) headers of uplink protocol data units (PDUs) in an uplink transmission buffer associated with the first DRB, based on a difference between a first configuration of the first DRB and a second configuration of the second DRB; and transmitting the uplink PDUs via the second DRB.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a modem. The apparatus detects reception of a low latency data packet. The apparatus starts a data activity timer determined based on the detection of the reception of the low latency data packet. The apparatus sends a disable low power message from the apparatus to a host device to disable a low power state of a link between the apparatus and the host device based on a duration of the data activity timer.

Abstract: Wireless communications systems and methods related to uplink buffer management are provided. In some aspects, a user equipment receives a synchronization acknowledgment message destined for a device tethered to the user equipment and transmitted by an application server at a network to which the user equipment is connected. In some aspects, the synchronization acknowledgment message includes an application server receiver window size indicating available buffer space in a receive buffer of the application server. The user equipment can modify the application server receiver window size in the received synchronization acknowledgment message prior to transmitting the received synchronization acknowledgment to the tethered device.

Abstract: This disclosure provides a method, apparatus, and computer-readable medium for wireless communication at a modem, comprising receiving, via an interface with a host, an internet protocol (IP) packet including a first transport protocol header and a first IP header. The IP packet has a size greater than a maximum transport unit (MTU) size allowable for each packet transmitted over a communication link. The modem segments the IP packet into a plurality of segments based on a segment size indicated by a segmentation policy. Each segment includes a respective derived segment transport protocol header and a respective derived segment IP header derived from the IP packet. Each of these derived headers includes at least one field based on the segmentation policy, and each of the segment transport protocol headers includes a checksum for the respective segment. Additionally, the modem transmits the plurality of segments over the communication link.

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.
