Abstract: This application provides a transmission parameter adjustment method and a communication apparatus. The transmission parameter adjustment method includes: increasing a downlink transmission bandwidth of a service from a first downlink transmission bandwidth to a second downlink transmission bandwidth, where the second downlink transmission bandwidth is less than or equal to a target downlink transmission bandwidth, and the target downlink transmission bandwidth is a smaller value between a maximum downlink bandwidth supported by a system and a maximum downlink bandwidth supported by a terminal device; reducing a downlink delay budget of the service from a first downlink delay budget to a second downlink delay budget based on the second downlink transmission bandwidth; and increasing an uplink delay budget of the service from a first uplink delay budget to a second uplink delay budget based on the second downlink delay budget.

Abstract: This disclosure provides a configuration method and apparatus. The method may include: receiving a first cycle from a core network element and a second cycle from a terminal, where the first cycle is an initial service cycle or a first traffic shaping service cycle, and the second cycle is a service cycle expected by the terminal; configuring a discontinuous reception DRX cycle for the terminal based on the first cycle and the second cycle; and obtaining first information, and sending sleep indication information to the terminal based on the first information. In this application, an access network device obtains cycle information of a service and the first information, to configure the DRX cycle that can match the service and the sleep indication information that can enable the terminal to enter a sleep state in time.

Abstract: A DRX configuration-based communication method, communication apparatus, and communication system are disclosed for determining a DRX active time, where a start time point of the active time is related to a data cycle; and monitoring a PDCCH in the DRX active time. A terminal determines a DRX active time of the terminal based on a data cycle, so that the DRX active time of the terminal can well match the data cycle.

Abstract: A data transmission method and a data transmission apparatus are provided, to help reduce a transmission delay of a service frame. The method includes: A terminal sends first indication information to a network device. The first indication information indicates a statistical parameter of a delay jitter of an arrival time of a service frame. The statistical parameter of the delay jitter is for determining a CG resource. The network device sends second indication information to the terminal. The second indication information indicates the CG resource. The CG resource is determined based on the first indication information. The terminal and the network device communicate the service frame based on the CG resource.
