Abstract: A network device sends downlink control information to a first terminal device. The downlink control information includes: time domain resource information, where the time domain resource is a time domain resource on which a first data channel is located; and frequency domain resource information, where the frequency domain resources are a frequency domain resource on which the first data channel is located and a frequency domain resource on which a second data channel is located. The second data channel is located on a time domain resource different from the time domain resource on which the first data channel is located. The first terminal device receives, on the determined time domain resource and frequency domain resource, a signal that is located on the first data channel and that is from the network device.

Abstract: This application provides a data transmission method and an apparatus, to reduce a quantity of times of repeated transmission of data, reduce power consumption of a terminal device, save transmission resources, and maintain a high time diversity gain. The method includes: A network device sends first information, and a terminal device receives the first information, where the first information is used to configure K repeated transmission occasions. The network device and the terminal device repeatedly transmit first data on N repeated transmission occasions in the K repeated transmission occasions, where the N repeated transmission occasions are discontinuous in time domain, K is an integer greater than 1, and N is an integer greater than or equal to 1 and less than K.

Abstract: Embodiments of this application disclose an access method and an apparatus. The method includes: a network device sends, in a first cell, information that indicates characteristic information of terminals allowed to access the first cell. A terminal determines, based on the indication of the information, whether to access the first cell. Alternatively, the terminal reports, in the first cell, characteristic information of the terminal to the network device, and the network device determines, based on the characteristic information reported by the terminal, whether to allow the terminal to access the first cell.
