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: 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.

The solution is used in a plurality of cycles including a first cycle and a second cycle which each includes M first durations, and the first duration includes N paging occasions. The solution includes: determining a first target paging occasion that is in an mth first duration of the first cycle, where a relative location of the first target paging occasion in the first cycle is different from a relative location of a second target paging occasion in the second cycle, and the second target paging occasion is a target paging occasion in an mth first duration of the second cycle; determining, based on the first target paging occasion, a time domain resource that is in the mth first duration of the first cycle; and receiving or sending the reference signal on the time-frequency resource.

Abstract: This application has disclosed a method for sending and transmission of a resource conflict indication and a communication apparatus. When determining that a reserved resource indicated by first SCI conflicts with a reserved resource indicated by second SCI, a first terminal device sends an RCI to a second terminal device at a determined time domain and/or frequency domain position before a conflict position; or when determining that a resource corresponding to first SCI conflicts with a resource corresponding to second SCI, a first terminal device sends an RCI to a second terminal device at a determined time domain and/or frequency domain position after a conflict position. The RCI is sent at the determined time domain and/or frequency domain position.

Abstract: An information sending method and an apparatus are provided. In the method, after sending a first message including uplink data to a network device, a terminal device receives first DCI from the network device, where the first DCI may include first indication information, and the first indication information is used to indicate that the network device has successfully demodulated the first message or used to indicate the terminal device to flush a HARQ buffer corresponding to the first message; and the terminal device may obtain the first indication information from the first DCI, and after obtaining the first indication information, the terminal device determines not to monitor a PDCCH search space within first duration after the first DCI. After sending the uplink data and receiving the first indication information from the network device, the terminal device may not monitor the PDCCH search space within specific duration.

Abstract: The present disclosure relates to methods and terminal devices for detecting a wake-up signal. A terminal device sends first information to a network device, where the first information indicates a reported gap, receives second information sent by the network device, and determines a configuration condition of a first gap and a configuration condition of a second gap based on the second information. The terminal device determines a target gap based on the reported gap, the configuration condition of the first gap, and the configuration condition of the second gap, and detects a wake-up signal at a detection position before a start position of the first paging opportunity in a paging time window, where the detection position is determined based on the target gap and maximum duration of the wake-up signal.

Abstract: This application provides a method for waking up a terminal, a terminal, and a network device. In technical solutions provided in this application, a network device determines, from a plurality of wake-up signals that can wake up a to-be-woken-up terminal and that need to be monitored by the to-be-woken-up terminal for one PO, a target wake-up signal of the to-be-woken-up terminal, and sends the target wake-up signal to the to-be-woken-up terminal. If the terminal detects, for the one PO, at least one wake-up signal of the plurality of wake-up signals that can wake up the terminal and that need to be monitored by the terminal, the terminal monitors a downlink control channel at the PO.
