Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain hybrid automatic repeat request (HARQ) information indicating whether the network node is configured to perform a retransmission of decoding information prior to an end of HARQ processes associated with the network node. The UE may receive, for a HARQ process associated with a downlink communication from the network node, a retransmission of a transport block (TB) that is associated with a reserved MCS when full decoding information for the TB is unavailable. The UE may perform, based on a reception of a retransmission, an action to proceed with the HARQ process, to restart the HARQ process, or to terminate the HARQ process, wherein the action is based on whether the network node is configured to perform the retransmission of the indication of the MCS. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. A device may transmit or receive multiple data packets via a data connection established via a wireless channel. The multiple data packets may be a sequence of data packets. The device may identify a quantity of duplicate acknowledgment (ACK) messages, where a first ACK message may be identified as being a duplicate ACK message based on a second ACK message indicating successful receipt of a same packet as the first ACK message and successful receipt of one or more subsequent packets in the sequence of data packets, and based on the second ACK message being generated within a time duration threshold of the first ACK message. The device may perform a duplicate ACK recovery procedure based on the quantity of duplicate ACK messages satisfying a trigger threshold.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a trigger indicating that the UE is to perform a global navigation satellite system (GNSS) acquisition process within a GNSS measurement gap, wherein a start time of the GNSS measurement gap is based at least in part on whether hybrid automatic repeat request (HARQ) feedback is enabled for a channel in which the trigger is received. The UE may perform the GNSS acquisition process within the GNSS measurement gap based at least in part on the trigger. Numerous other aspects are described.

Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE obtains multiple buffer status reporting (BSR) tables and multiple sets of one or more timers. Each BSR table of the multiple BSR tables corresponds to one logic channel group (LCG) of multiple LCGs. The UE further communicates with a network entity based on one BSR table selected from the multiple BSR tables and one set of timers selected from the multiple sets of one or more timers. The method enables the UE to obtain multiple BSR tables and BSR timers and select corresponding BSR tables and timers according to specific characteristics of the traffic.

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 systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a user equipment (UE) is configured to manage a state variable (associated with a radio link control (RLC) entity or a packet data convergence protocol (PDCP) entity) that enables the UE to maintain synchronization with a base station during a communication session. For example, a base station may transmit, to the UE, a control PDU or a synchronization PDU that includes a value of a state variable maintained by a base station to enable the UE to update its state variable to maintain synchronization with the base station. Other aspects and features are also claimed and described.

Abstract: A UE may include one or more application processors and a modem processor. The modem processor may include flow priority engine configured to receive, from the one or more application processors, requests for determining priority treatment of one or more packet filters of one or more uplink transmissions and transmit the one or more uplink transmissions to a base station based on prioritiers of the one or more uplink transmissions. The priorities of the uplink transmissions may be determined based on at least one of the requests for priority treatment received from the one or more application processors, mapping of uplink transmissions to radio bearers, the priorities of the radio bearers, or one or more configuration rules.

Abstract: A UE may be configured to receive, from a base station, consecutive DCI messages including respective indicator values that are equal, each of the indicator values indicating an association with one of a new transmission or a retransmission. The UE may be further configured to remain in an awake state for at least a portion of a scheduled sleep state of a DRX cycle scheduled by the base station based on the respective indicator values being equal across the consecutive DCI messages. A base station may be configured to transmit, to a UE, a DCI message indicating a set of resources allocated to the UE for a transmission, and to transmit, to the UE, data to synchronize a DRX cycle with the UE based on an absence of the transmission from the set of resources allocated to the UE.
