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.

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 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: 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: A user equipment of a wireless communication system using carrier aggregation and a carrier aggregation control method thereof are provided. The user equipment includes an abnormal event detector and a processor electrically connected with the abnormal event detector. The abnormal event detector is configured to detect an abnormal event indicating that the user equipment is in an abnormal state. The processor is configured to control a component carrier of the wireless communication system in response to detecting the abnormal event. The carrier aggregation control method is applied to the user equipment to implement the operations.

Abstract: The invention provides an output control apparatus for adjusting the output level of a pulse width modulation (PWM) signal by changing the amplitude level of the output PWM signal. The output control apparatus comprises a control signal generator, a digital-to-analog converter (DAC), and an output circuit. The control signal generator generates a digital control signal. The DAC outputs a predetermined level according to the digital control signal. The output circuit with a negative feedback loop receives the PWM signal and receives the predetermined level by the negative feedback loop. While the PWM signal is logic number “0”, the negative feedback loop is not switched on, so as to control the level of the PWM signal at a base level. While the PWM signal is logic number “1”, the negative feedback loop is switched on, so as to control the level of the PWM signal at the predetermined level.
