Methods, systems, and devices for wireless communications are described. For instance, a flow control layer of a UE may provide a capability message to an application layer including an indication that the UE supports a service for providing flow control information for support of extended reality traffic and may receive a message from an application of the application layer registering a flow associated with the application with the service. The flow control layer may provide, to the application via the service, an indication that a quantity of packets or bytes in a buffer of the flow control layer fails to satisfy a threshold. The UE may obtain, from the application, a packet associated with the flow based on providing the indication that the quantity of packets or bytes in the buffer fails to satisfy the threshold and may transmit, to a network entity, a message including the obtained packet.

Uplink packet management for user interaction delay reduction

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.

Handover indication for data stream

In an embodiment, a serving BS of a UE may transmit a PDCCH communication to the UE. The PDCCH communication triggers a partial RACH procedure, whereby a RACH transmission is performed. In some designs, the RACH transmission is for positioning, and positioning measurements are performed at the serving BS and (optionally) at one or more non-serving BSs. In some designs, measurement data based on the positioning measurements are conveyed to a position estimation entity (e.g., LMF), which performs a positioning estimate of the UE.

Partial random access channel procedure

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. 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 user equipment (UE) may receive, from a network node, an indication of one or more data radio bearers between the UE and the network node that are configured for application data unit (ADU) traffic. The UE may communicate, with an application server, one or more ADU traffic flows through the network node using the one or more data radio bearers. Numerous other aspects are provided.

Application data unit architecture and signaling

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.

Traffic and feedback management based on frame decoding

A user equipment (UE) transmits reference signals for positioning while in Idle or Inactive state. While in a connected state, the UE is pre-configured with Sounding Reference Signal (SRS) resource configuration including at least one of timing adjustment (TA) and an uplink (UL) transmission spatial filter. The UE transmits positioning SRS while in Idle or Inactive mode based on the pre-configuration. The TA and UL transmission spatial filter may be updated by a serving base station using control signals or a paging message received by the UE while in in Idle or Inactive mode. The validity of the TA and UL transmission spatial filter may be monitored using expiration timers or a relative position change threshold. The reference signals transmitted may be based on a UE may Physical Random Access Channel (PRACH), which is insensitive to TA changes. A long sequence PRACH may be used for improved positioning accuracy.

Methods and apparatus for supporting positioning in idle or inactive mode

Certain aspects of the present disclosure provide techniques wireless communication by a user equipment (UE), comprising receiving an uplink (UL) grant from a network entity, wherein the UL grant schedules the UE to transmit an UL channel transmission associated with a plurality of logical channels (LCs), and the UL grant indicates a modulation and coding scheme (MCS) for transmitting the UL channel transmission associated with the plurality of LCs, receiving a plurality of MCS offsets, and transmitting the UL channel transmission associated with one or more LCs of the plurality of LCs based on the MCS indicated in the UL grant and the plurality of MCS offsets.

Uplink logical channel specific modulation and coding scheme signaling

Methods, systems, and devices for wireless communications are described. A device may aggregate multiple data bits into a group of data bits associated with an application on the device. The device may determine quality of service parameters associated with the group of data bits. The quality of service parameters may include an error rate associated with the group of data bits, a delay budget associated with the group of data bits, timing information associated with the group of data bits, or content policy information associated with the group of data bits, or a combination thereof. The device may transmit the group of data bits to another device in the wireless communication system. The group of data bits may include group header information including an indication of the quality of service parameters.

Group-based wireless communications

Methods, systems, and devices for wireless communications are described. A wireless communications entity, such as a user equipment (UE), a base station, a network core, or an application server, may identify a round-trip time (RTT) latency requirement that may pertain to a round-trip latency in wireless communications between the UE and the base station. The wireless communications entity may identify a one one-way directional delay budget that satisfies the RTT latency requirement for an application of an application server. The application server may be in communication with the UE via the base station. The wireless communications entity may modify a value of the one-way directional delay budget and transmit a message that is associated with the modified value of the one one-way directional delay budget.

Round-trip time as a latency performance indicator

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive application data for transmission via an additional network node. The network node may provide the application data to the additional network node, the application data having one or more indications of groupings into application data units (ADUs) added before being provided to the additional network node. Numerous other aspects are described.

Application data units

In embodiments of systems and methods for managing acknowledgement packets in an uplink data packet stream including secure or encrypted data packets, a computing device may identify uplink acknowledgement (UL ACK) packets within the uplink data packet stream, and may accelerate processing of the identified UL ACK packets. In some embodiments, UL ACK packets may be identified based on whether packet lengths of packets meet a packet length threshold or meet a packet length range. In some embodiments, UL ACK packets may be identified based on information for identifying such packets receiving via a cross-layer application program interface (API). In some embodiments, UL ACK packets based whether packets include a specified differentiated services field codepoint (DSCP) in a packet header portion that is not encrypted.

Managing acknowledgement packets in an uplink data packet stream

Disclosed are systems, methods, and non-transitory media for providing signaling consideration for wireless positioning with disjoint bandwidth segments. For instance, one or more indications of a preferred bandwidth configuration can be transmitted by a user equipment. Based on the one or more indications, the user equipment can receive a positioning configuration that indicates disjoint bandwidth segments containing a positioning reference signal based on the preferred bandwidth configuration. In response, the user equipment can then determine one or more positioning measurements based on the positioning reference signal in the disjoint bandwidth segments.

Signaling consideration for new radio positioning with disjoint bandwidth segments
