Abstract: A communication method includes that, when a terminal device receives indication information used by a network device to indicate the terminal device to work on a non-dormant bandwidth part (BWP) in a secondary cell, the terminal device can determine a specific BWP on which the terminal device is to work, and perform a corresponding operation. A network device generates indication information, and sends the indication information to a terminal device, where the indication information is used to indicate the terminal device to work on a non-dormant BWP in a first secondary cell. Then, the terminal device enables, according to the indication information, the terminal device to work on a first BWP, where the first BWP is the non-dormant BWP in the first secondary cell.

Abstract: Embodiments of the present invention disclose a wireless data transmission method, including: obtaining a repetition quantity required for data transmission of each user equipment (UE) in a management range, and determining a round trip time (RTT) of the UE according to obtained repetition quantity information of the UE, process quantity information of the UE, and a transmission time interval (TTI). A repetition quantity required by a UE may be learned of by using repetition quantity information of the UE. Therefore, for a coverage capability of each UE, each RTT can include as few processes as possible, provided that a requirement of the UE for a repetition quantity is met. In this way, a probability of successful data decoding may be efficiently improved, thereby efficiently improving a coverage capability of UE in wireless communication.

Abstract: A message transmission method is provided. User equipment may receive a power saving message from a network device, where the power saving message carries indication information of a short message, and the short message includes at least one of the following: a public warning system notification or system information modification information. Then, the user equipment obtains the short message from the power saving message. In this way, when the user equipment is in a connected state, the user equipment may obtain the short message by using the power saving message, for example, a PoSS, instead of by monitoring a paging PDCCH; and when the UE is in a sleep state, the UE is not woken up to monitor the paging PDCCH. This reduces power consumption of the user equipment in the connected state.
