Abstract: This application provides example communication methods and apparatuses. One example method includes performing, by a network device on a preconfigured resource, data demodulation on uplink data from a terminal device. The network device can then send downlink control information (DCI) to the terminal device, where the DCI includes first indication information, and if the uplink data fails to be demodulated, or it is determined, based on a result of the data demodulation, that the terminal device needs to retransmit the uplink data, the first indication information indicates either the terminal device to initiate random access or EDT and retransmit the uplink data or that the uplink data fails to be demodulated.

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.

Abstract: Embodiments of this application provide a wireless communication method, device, and system. The method includes: A terminal device receives first information from a network device, where the terminal device currently uses a first BWP, and the first information indicates that in minK0 time units after the terminal device receives scheduling downlink control information (DCI), there is no downlink shared channel (PDSCH) scheduled by the scheduling DCI, and/or in minK2 time units after the terminal device receives the DCI, there is no physical uplink shared channel (PUSCH) scheduled by the scheduling DCI; the terminal device receives the scheduling DCI from the network device, where the scheduling DCI indicates the terminal device to switch from the first BWP to a target BWP; and the terminal device determines a first time period based on a bandwidth part (BWP) switch delay and the first information, where the BWP switch delay includes N time units.

Abstract: Example communication methods and apparatus are described. In one example method, a first cell includes a plurality of terminal devices that can transmit uplink data on a same uplink time-frequency resource. A first terminal device in the plurality of terminal devices determines a reference time domain location based on a preconfigured uplink time-frequency resource, where the reference time domain location is the same as a reference time domain location determined by another terminal device in the plurality of terminal devices. The first terminal device determines a time domain location that is (first duration×N H+second duration×(N−1)) away from the reference time domain location as a start time domain location of X gaps. The first terminal device further determines a time domain location that is (first duration×(M−1)+second duration x (M−1)) away from the reference time domain location as a start time domain location of Y first durations, where Y=X or Y=X+1. Uplink data is sent by the first terminal device to a network device on a first time-frequency resource used to transmit uplink data.
