Abstract: An application server side network predicts, based at least on a feedback of traffic latency, a congestion in a traffic between the application server side network and at least one user equipment (UE) of one or more UEs in a radio access network (RAN) of the application server side network based on a total RAN network load and traffics between the application server side network and the one or more UEs. The application server side network controls the congestion in response to an increase in a queueing delay in the traffic between the application server side network and the at least one UE as well as an increase in a data rate and quality of service (QoS) parameters of the traffic, with the traffic including an extended reality (XR) traffic associated with an XR client-side application executed on the at least one UE.

Abstract: A network communicates an extended reality (XR) traffic with a user equipment (UE) with frame error concealment to limit a duration of temporal error propagation. The network also transmits a report of failure or a request for retransmission to the UE in an event of a network transmission failure.

Abstract: Techniques pertaining to subband full duplex (SBFD) user equipment (UE) reporting hard constraints on full-duplex scheduling to network nodes are described. Such techniques include establishing full-duplex communication between a UE and a network node such that the UE is able to transmit data to the network node and receive data from the network node simultaneously in time. The techniques further include reporting by the UE to the network node one or more hard constraints on a full-duplex scheduling of communication resources that is performed by the network node for the UE during the full-duplex communication.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives a configuration of physical random access channel (PRACH) occasions from a base station. The configuration indicates one or more PRACH occasions located in each time unit of a set of time units. The UE determines whether a first PRACH occasion in a first time unit of the set of time units is valid in the time domain by assessing whether the first time unit is partitioned or non-partitioned. The UE transmits a random access preamble at the first PRACH occasion when the first PRACH occasion is valid in the time domain and is also valid in the frequency domain.
