Abstract: Methods, systems, and devices for wireless communications are described. A system may support techniques for triggering user equipment (UE) assistance information (UAI) based on mobility, wake up signal (WUS) configuration, or both. In some cases, a UE may communicate with a network node (e.g., a base station) on a first channel according to a discontinuous reception (DRX) configuration. The UE may determine that a speed of the UE satisfies a mobility threshold and may transmit UAI requesting one or more updated DRX configuration parameters based on the speed of the UE satisfying the mobility threshold. Additionally or alternatively, the UE may receive signaling configuring the UE to monitor for WUSs and may transmit UAI requesting one or more updated DRX configuration parameters based on the WUS configuration. The UE may receive control signaling configuring the DRX configuration with the one or more requested parameters in response to the UAI.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a control message indicating a resource configuration for uplink and downlink transmissions. The UE may determine an uplink buffer threshold for a modem buffer of the UE based on the resource configuration. The UE may transmit, to the base station, a feedback request message requesting that the base station provide feedback for at least one previously transmitted uplink packet based on a comparison of an amount of previously transmitted uplink data and scheduled uplink data stored in the modem buffer relative to the uplink buffer threshold. The UE may receive, based on transmitting the feedback request message, a feedback response message corresponding to a first previously transmitted uplink packet of the at least one previously transmitted uplink packet.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, such as a user equipment may identify a size capability for a buffer associated with a protocol layer of the UE. The buffer may be a layer two buffer and the protocol layer may be a layer two protocol layer. The UE may transmit, to a base station serving the UE, an indication of the identified size capability for the buffer. In some cases, the UE may transmit the indication of the identified size capability in a UE capability report in radio resource control signaling. The UE may then communicate, with the base station 105, data that is scheduled based on the transmitted indication.

Abstract: Methods, systems, and devices for wireless communication are described to support entering a fast-negative acknowledgement (NACK) mode. A user equipment (UE) may enter a fast-NACK mode and may decrease a value of a respective timer for one or more wireless connections (e.g., may override the timer independently for each connection). The timer may be referred to as a retransmission request time duration. If configured with two or more component carriers (CCs), the UE may determine a value of the timer based on a location of a data hole within the two or more CCs. Based on entering the fast-NACK mode, the UE may override a configured timer for the respective wireless connection with a new, shorter timer. Based on expiration of the new timer, the UE may transmit an RLC NACK to a base station via the corresponding wireless connection.

Abstract: Aspects disclosed in the detailed description include power saving techniques in computing devices. In particular, as data is received by a modem processor in a computing device, the data is held until the expiration of a modem timer. The data is then passed to an application processor in the computing device over a peripheral component interconnect express (PCIe) interconnectivity bus. On receipt of the data from the modem processor, the application processor sends data held by the application processor to the modem processor over the PCIe interconnectivity bus. The application processor also has an uplink timer. If no data is received from the modem processor before expiration of the uplink timer, the application processor sends any collected data to the modem processor at expiration of the uplink timer. However, if data is received from the modem processor, the uplink timer is reset.

Abstract: A method and apparatus for receiving a notification of missing packets include receiving a set of data packets transmitted by a device and having a corresponding set of sequence numbers, identifying one or more data packets having corresponding sequence numbers that fall within the set of sequence numbers and are yet to be received, receiving an indication from the device that the one or more data packets will not be transmitted by the device, and processing the set of data packets without the one or more data packets in response to receiving the indication.

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: Methods, systems, and devices for wireless communications are described. In aspects, a wireless device such as a user equipment (UE) may identify an amount of acknowledgement (ACK) reduction associated with an applications processor. The amount of ACK reduction may be determined based on a communication from the applications processor, or an ACK frequency in a group of packets received from the applications processor. The UE may determine whether to modify an ACK management scheme (e.g., a transmission control protocol (TCP) ACK coalescing scheme) based at least in part on the amount of ACK reduction associated with the applications processor. The UE may modify the ACK management scheme. The UE may transmit ACKs in accordance with the modified ACK management scheme. Numerous other aspects are provided.
