Abstract: A communication apparatus includes a radio transceiver, an application processor and a modem processor. The radio transceiver transmits or receives wireless signals to or from a network device in a wireless network to communicate with the network device via a communication link. The application processor is configured to run one or more application programs. The modem processor is coupled to the radio transceiver and the application processor and configured to perform operations including: evaluating a future condition of the communication link according to at least one communication parameter or at least one communication event to obtain an evaluation result; and sending a first indication to the application processor to inform the application processor of the evaluation result. Responsive to reception of the first indication, the application processor is further configured to perform operation including: adapting a codec for multimedia processing of data received from the network device.

Abstract: Examples pertaining to improvement on user equipment (UE) uplink latency in wireless communications are described. When an apparatus is in a special mode, a processor of the apparatus transmits to a network a request for permission to perform an uplink (UL) transmission for a plurality of times. The processor then receives from the network a grant. In response to receiving the grant, the processor performs the UL transmission to the network. In transmitting the request for the plurality of times, the processor transmits the request for the plurality of times at a frequency higher than a frequency at which the request to perform UL transmissions is transmitted to the network when the apparatus is in a normal operational mode.

Abstract: A user equipment and a timing advance value updating method thereof are provided. The UE determines that a scheduling request transmission counter reaches a maximum number of SR transmission and determines whether a time alignment timer is still running after the scheduling request transmission counter reaches the maximum number of SR transmission. If the time alignment timer is still running, the UE drops the time alignment timer.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. In certain configurations, the UE establishes a connection supporting an extended reality (XR) application service with a base station. The UE reports, to the base station, a delay status report (DSR) to indicate a buffer size for data to be transmitted to the base station. The DSR includes timing information. The UE receives a configuration instruction from the base station. The UE configures resources on the UE according to the configuration instruction to transmit the data to the base station.
