Abstract: The present disclosure relates to wireless communication methods, terminal devices, and network devices. In one example method, a network device sends timing advance timer (TAT) configuration information to a terminal device, where the TAT configuration information is used by the terminal device to configure duration of a TAT. The terminal device receives the TAT configuration information sent by the network device. The terminal device configures the TAT based on the TAT configuration information, and asynchronously sends uplink data to the network de vice based on a running status of the TAT. The network device receives the uplink data sent by the terminal device based on the TAT configuration information.

Abstract: This application provides a data transmission method and apparatus, and a system, to reduce outdated information sent by a terminal to a network device, thereby reducing improper scheduling decisions made by the network device. The method includes: sending a first data packet to a network device, and storing the first data packet; receiving a first uplink grant from the network device, and skipping using the first uplink grant to perform uplink transmission; receiving a second uplink grant from the network device, where the second uplink grant is a grant for retransmission and generated due to a failure of transmission on the first uplink grant; and ignoring the second uplink grant, or transmitting a second data packet to the network device based on the second uplink grant.

Abstract: Example data processing methods and apparatuses are disclosed. In one example data processing method, a first terminal obtains packet delay budget adjustment information, where the packet delay budget adjustment information is used to indicate an adjusted packet delay budget, a packet delay budget adjustment amount, or a packet delay budget adjustment range. The first terminal adjusts a size of a jitter buffer based on the packet delay budget adjustment information, and then buffers data based on the adjusted jitter buffer.

Abstract: Various embodiments provide a resource allocation method and an apparatus. In those embodiments, a terminal device obtains a first parameter indicating a maximum service data volume to be provided by an access network device for a first service in a first time length; and determines, based on the maximum service data volume, a resource of a media access control protocol data unit MAC PDU, the resource being occupied by buffered data of the first service. In those embodiments, the terminal device determines, based on the maximum service data volume of the first service, the resource of the MAC PDU. Compared with a conventional method, the maximum service data volume of the first service is considered. This helps improve reasonableness of allocating the resource of the MAC PDU to the data of the first service.

Abstract: An access network device sends first information and second information to a terminal, where the first information includes a value set of a communication time interval, and the second information indicates a value of the communication time interval in the value set, and the value is used to determine timing duration of a hybrid automatic repeat request (HARQ) round trip time (RTT) timer. The communication time interval includes at least one of a time interval from the terminal receiving downlink scheduling grant information to the terminal receiving downlink data scheduled by using the downlink scheduling grant information, a time interval from the terminal receiving downlink data to the terminal sending HARQ feedback information of the downlink data, and a time interval from the terminal receiving uplink scheduling grant information to the terminal sending uplink data scheduled by using the uplink scheduling grant information.
