CPC classification number: H04L27/2649 , H04L5/0051
Abstract: A signal demodulation method, a signal transmission method, and a related apparatus. The signal demodulation method includes: a terminal device receives a first tracking reference signal from a first transmission reception apparatus of a single frequency network cell; a second tracking reference signal occupying different time-frequency from the first tracking reference signal from a second transmission reception apparatus of the single frequency network cell; and receives indication information indicating tracking reference signals from the first transmission reception apparatus or the second transmission reception apparatus; determines, based on the one or more tracking reference signals for receiving the downlink signal, a first carrier frequency on which the downlink signal is to be received; receives the demodulation reference signal and the downlink data based on the first carrier frequency; and demodulates the downlink data based on the demodulation signal.

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.
