Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an application server may receive an indication that a handover is likely for a user equipment (UE), wherein the UE is in communication with the application server to receive a data stream. The application server may provide the data stream using values of one or more parameters to reduce an impact of a communication interruption associated with the handover. Numerous other aspects are described.

Apparatuses and methods for resolving SR, BSR, and/or PUSCH data delay from MG conflict for low latency. An apparatus is configured to obtain a configuration of a delay threshold associated with an UL PDCP queuing delay for a transmission buffer. The apparatus is configured to measure a packet buffer time in which at least one UL data packet is in the transmission buffer, where the at least one UL data packet is associated with a SR, a BSR, or PUSCH data. In addition, the apparatus is configured to transmit, for a network node, at least one of the SR, the BSR, or the PUSCH data during a portion of a MG in a MG interval or outside of the MG based on the packet buffer time being less than or greater than or equal to the delay threshold.

Resolving SR and BSR delay from measurement gap conflict for low latency

The apparatus may be configured to generate, for a set of data packets associated with an application, a set of parity bits, generate an encoded data transmission associated with a UPF including the set of data packets and the generated set of parity bits, and to output, for a receiving device associated with the application, the encoded data transmission. The apparatus may be configured to obtain an encoded data transmission associated with a UPF including a first plurality of bits associated with a set of data packets associated with an application and a second plurality of bits associated with a set of parity bits based on the set of data packets, to decode the encoded data transmission to generate the set of data packets, and output, for one of an application client or an application server associated with the application, the set of data packets.

System architecture of network coding at user plane function

Methods, systems, and devices for wireless communications are described. For example, a network entity may output, and a user equipment (UE) may receive, a first control message identifying a first discontinuous reception (DRX) cycle and a second, different DRX cycle for the UE to use, the first and second DRX cycles having a first and second active duration, respectively. The network entity may also output a second control message identifying periodic resources for the UE to use to monitor for a periodic signal, the periodic resources being outside at least the first active duration. The UE may monitor for, and the network entity may output, based on the periodic resources being outside the first active duration, the periodic signal during the first active duration based on updating the first active duration, updating the periodic resources, or both.

Monitoring for periodic signals during non-uniform discontinuous reception cycles

Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) generating a set of multimedia packets including a first multimedia packet and a second multimedia packet that is generated after the first multimedia packet. The UE may add the set of multimedia packets to a queue and apply an uplink packet handling protocol. Using the uplink packet handling protocol, the UE may discard the first multimedia packet and transmit, to a base station, the second multimedia packet. Using the second multimedia packet, a server in communication with the base station may generate a video frame and transmit the video frame to the UE via the base station.

Techniques for multimedia uplink packet handling

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive multiple transport blocks (TBs) representing an application data unit (ADU) from a base station. The base station may transmit an indication that the UE is to provide ADU level feedback. The UE may determine the ADU level feedback based on whether the ADU is successfully received and decoded or not. The UE may indicate the ADU level feedback for the TBs to the base station. The base station and the UE may communicate according to the ADU level feedback.

Flexible feedback with outer coding

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive time sensitive communication assistance information (TSCAI), associated with extended reality data traffic, that comprises at least one of multimedia cadence information, timing update information, timing offset information, configurable parameter set information, or extended reality specific traffic pattern information. The network node may transmit feedback associated with the TSCAI. Numerous other aspects are described.

Time sensitive communication assistance information for extended reality data traffic

Methods, systems, and devices for wireless communication are described. A network node may determine a first time location associated with a peak in data traffic for multiple devices in communication with a communications network including the network node. The network node may determine a second time location for the peak in the data traffic for a subset of the devices based on a threshold for an overall peak in data traffic for the multiple devices. The network node may transmit a signal that indicates the second time location for the peak in the data traffic for the subset of devices. The network node may communicate the data with the subset of devices based on the signal indicating the second time location.

Peak traffic position adjustment for wireless communication

Methods, systems, and devices for wireless communications at a user equipment (UE) are described. A user equipment (UE) may receive a downlink control information scheduling transmission of periodic multimedia traffic bursts to the UE with a first periodic cadence. The UE may receive control signaling from the UE indicating that the UE is to periodically transmit sounding reference signals to the base station according to a second cadence, which may be a multiple of the first periodic cadence. Additionally or alternatively, the UE may receive control signaling indicating that the UE is to transmit a sounding reference signal at a time associated with a beginning of at least one of the periodic multimedia traffic bursts. The UE may transmit one or more sounding reference signals to the base station in accordance with the control signaling.

Sounding reference signal coordination for periodic traffic

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that the UE has received, from a network, a sufficient quantity of protocol data units (PDUs) to decode a frame. Accordingly, the UE may indicate, to the network, that the UE has decoded the frame. Similarly, the UE may determine that the network has received, from the UE, a sufficient quantity of PDUs to decode a frame. Accordingly, the UE may refrain from transmitting one or more additional PDUs associated with the frame. Additionally, or alternatively, the UE may receive, from the network, an indication to disable some feedback to the network. Accordingly, the UE may refrain from transmitting one or more feedback signals based at least in part on the indication. Numerous other aspects are described.

A user equipment (UE) may be configured to estimate, during a first time interval, at least one of a first interference level for a first radio access technology (RAT) caused at least in part by a second RAT, a second interference level for the second RAT caused at least in part by the first RAT, or a combination thereof. The UE may transmit a control message to a base station using the first RAT based on at least one of the first estimated interference level, the second estimated interference level, or a combination thereof. The UE may then communicate, based on the control message and during a second time interval, with the base station using the first RAT and with a wireless device using the second RAT, the second time interval being after the first time interval.
