Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, information identifying uplink and downlink transmission opportunities that are based at least in part on downlink traffic from an application server. The UE may communicate the uplink and downlink transmission opportunities to an application client connected to the UE via a cross-layer application programming interface (API). The UE may transmit one or more uplink communications including traffic from the application client in one or more of the uplink and downlink transmission opportunities. Numerous other aspects are described.

Abstract: Aspects of the disclosure are directed to an apparatus configured for wireless communication. In certain aspects, the apparatus is configured to generate data (e.g., generate uplink data and store the data in a buffer until uplink resources are granted for transmission of the data). In certain aspects, the apparatus is configured to transmit, to a network node, a scheduling request (SR) comprising an indication of a size of the generated data, wherein the indication of the size of the generated data is configured to indicate whether the size of the generated data is greater than or equal to a threshold value, or less than or equal to the threshold value.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station via a first instance of a periodic data burst, where the periodic data burst may include one or more uplink or downlink transmissions scheduled on a first bandwidth part (BWP). The UE may start a bandwidth switching timer at the beginning of the first instance of the periodic data burst, and determine whether the bandwidth switching timer has expired upon expiration of an inactivity timer that was triggered by receipt of one or more downlink control channel messages. The UE may operate, based on the determination, on one of the first BWP or a second BWP during at least a portion of a time period that extends from the expiration of the inactivity timer and a beginning of a second instance of the periodic data burst.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support enhanced scheduling request configurations. A user equipment (UE) may obtain, at a packet data convergence protocol (PDCP) layer of the UE, information associated with a data packet for transmission by the UE. The UE may transmit a scheduling request that indicates information regarding an elapsed time period since the information associated with the data packet was obtained at the PDCP layer of the UE, or whether the data packet is a final packet of a set of data packets, or both. A network entity may receive the scheduling request and determine scheduling information for uplink communications by the UE based on the information regarding the elapsed time period, or whether the data packet is the final data packet, or both. The network entity may transmit the scheduling information to the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may account for jitter in communications with a user equipment (UE) by adjusting connected mode discontinuous reception (CDRX) configuration parameters for the UE based on estimated downlink traffic arrival times. For a downlink traffic burst, the network entity may estimate a traffic arrival offset based on determining a traffic periodicity, an estimated arrival time associated with one or more packets of a traffic burst, and at least one jitter parameter. The jitter parameter may represent an uncertainty in the arrival time of the traffic burst. The network entity may select a CDRX offset value based on the estimated traffic arrival offset. The network entity may transmit (e.g., to a UE, such as an extended reality (XR) device) a message indicating the CDRX offset value, for example, as part of a CDRX configuration.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive control information that identifies criteria to use for determining a delivery status of a protocol data unit (PDU) set that includes multiple PDUs. The PDU set may be associated with an application layer of the UE. Accordingly, the UE may receive at least a portion of the PDU set, and may determine the delivery status of the PDU set based on the received portion of the PDU set and the criteria identified by the control information. The delivery status of the PDU set may refer to whether the PDU set was successfully delivered to the UE. The delivery status of the PDU set may be based on a quantity of bits or PDUs in the received portion of the PDU set, a threshold quantity of bits or PDUs, or a combination thereof.

Moreover, the UE transmits, to the network node, the one or more data packets, which may include a protocol data unit (PDU), a group of PDUs, or a PDU set or burst.
