Abstract: A method for scheduling resources is disclosed herein. A terminal device receives a downlink control information (DCI) indication sent by a network device. The DCI is used to indicate a first resource, and the first resource is a time-frequency resource for a narrowband physical uplink shared channel (NPUSCH) format 2 transmission. The NPUSCH format 2 is used to bear downlink hybrid automatic repeat request-acknowledgment (HARQ-ACK) feedback information. The terminal device determines the first resource according to the DCI, and sends a scheduling request to the network device on the first resource.

Abstract: Example communication methods and apparatus are described. One example method includes determining a random access preamble by a terminal device. The random access preamble includes six symbol groups. The terminal device determines a frequency location of the random access preamble based on random access configuration information and a preset rule. A frequency hopping interval between a first symbol group and a second symbol group and a frequency hopping interval between a fifth symbol group and a sixth symbol group are equal and are first intervals. A frequency hopping interval between the second symbol group and a third symbol group and a frequency hopping interval between a fourth symbol group and the fifth symbol group are equal and are second intervals. A frequency hopping interval between the third symbol group and the fourth symbol group is a third interval. The random access preamble is sent based on the frequency location.

Abstract: Example signal transmission methods and apparatus are described. One example method includes generating a first signal by a network device, where the first signal is used to indicate to a terminal device whether there is paging scheduling information on a first paging occasion. The network device determines a first resource based on at least one of a paging configuration parameter, a first parameter set, a terminal device identifier, or a terminal identification code. The network device sends the first signal to the terminal device on the first resource. The signal transmission methods, network device, and terminal device in the embodiments of this application enable the terminal device to determine, based on the first signal, whether to listen on a downlink control channel, reducing power consumption of the terminal device.

Abstract: A monitoring method and an apparatus are provided. The method includes transmitting, by a terminal device, first information based on a first repetition number, where the first repetition number is less than or equal to a second repetition number, and the second repetition number is a maximum repeat transmission number of the first information. The method also includes determining, by the terminal device, a scheduling end moment of the first information based on the second repetition number, where the scheduling end moment of the first information is a transmission end moment of the first information when the first information is transmitted based on the second repetition number. The method further includes starting or restarting, by the terminal device, a timer at the scheduling end moment of the first information, and monitoring a PDCCH search space before the timer expires or stops.
