Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate a first service associated with a first subscriber identity module (SIM) of the UE and a first priority. The UE may initiate a second service associated with a second SIM of the UE and a second priority. The UE may switch the first priority and the second priority during at least part of the first service or the second service. The UE may perform a communication in accordance with at least one of the first priority or the second priority. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for configuring a device-configured split data threshold for utilizing split data radio bearers (DRBs). A method that may be performed at a user equipment (UE) includes setting a device-configured split data threshold to a value that is less than or equal to a network-configured split data threshold value in response to the network-configured split data threshold value being greater than a first buffer threshold value associated with a data buffer of the UE, monitoring an amount of data in the data buffer, and triggering a first scheduling request (SR) associated with a first communication link and a second SR associated with a second communication link in response to the amount of data in the data buffer being greater than the device-configured split data threshold value.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may wake up from a sleep mode of a discontinuous reception (DRX) cycle based on receipt of uplink data. The UE may determine if an elapsed time between a prior receipt of one or more reference signals and an uplink transmission to the base station after waking up from the sleep mode is less than a threshold time value. If the elapsed time is less than the threshold time value, the UE may transmit an uplink transmission associated with the received uplink data prior to receiving one or more reference signals that may be used to update transmission parameters for uplink transmissions. If the elapsed time is at or above the threshold value, the UE may wait to receive the one or more reference signals and update the transmission parameters prior to the uplink transmission.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a modem of a user equipment (UE) and a data source, such as an application processor or a tethered client, may support for flow control enforcement per service flow. For example, the modem may transmit, to the application processor, a first flow control command for a first data traffic including non-prioritized data. The application processor, based on the first flow control command, may transmit, to the modem, the first data traffic including the non-prioritized data according to the first flow control command while also transmitting a second data traffic including prioritized data without flow control. The modem and the application processor may support such selective flow control enforcement based on a priority of a service flow based on maintaining multiple buffers at the modem or based on defining multiple thresholds of one buffer associated with triggering flow control.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first configuration to perform an uplink communication using a first frequency spectrum band. The UE may receive a second configuration to receive a downlink communication using a second frequency spectrum band. The UE may determine an interference caused by at least one of the first frequency spectrum band or the second frequency spectrum band. The UE may reroute, based at least in part on the determination, the uplink communication to a first uplink path or a second uplink path associated with the first frequency spectrum band. Numerous other aspects are provided.

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: 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: Methods, systems, and devices for wireless communications are described. A wireless device such as a user equipment (UE) may receive a first control message that indicates a set of scheduled uplink communications, where the set of scheduled uplink communications include a set of transmission opportunities for transmitting one or more uplink messages. The UE may calculate a first duration between an availability of uplink data at the UE and a transmission opportunity of the set of transmission opportunities for transmitting the uplink data. The UE may then transmit a scheduling request for the uplink data based on the first duration being greater than a second duration, the second duration being either a duration between sending the scheduling request and receiving an uplink grant, or a latency threshold duration.
