Abstract: This application provides an information transmission method and a communications device. A first communications device sends first indication information to a second communications device, where the first indication information indicates a frequency resource used by the second communications device to send data in a time unit and a frequency resource used by the second communications device to receive data in the time unit, the frequency resource used to send data and the frequency resource used to receive data belong to a same frequency band, the frequency resource used to send data and the frequency resource used to receive data are differentiated based on frequencies in the time unit, and the frequency band is a segment of continuous frequency resources in frequency domain. In the foregoing information transmission method, the first communications device can flexibly allocate the frequency resources based on a network requirement, thereby improving resource utilization.

Abstract: This application provides a communication method, a network device, and a relay device. A first network device determines a first resource, where the first resource includes a resource used by a second network device to send a first signal to a second relay device, or the first resource includes a resource configured by the second network device for a first signal with zero power. The first network device sends first configuration information to a first relay device, where the first configuration information is used by the first relay device to determine a second resource for sending a second signal, and the second resource is a part or all of the first resource. According to embodiments of this application, relay devices can discover each other, thereby improving signal transmission efficiency.

Abstract: Embodiments of the present disclosure provide an uplink access method, a base station, and user equipment. The method includes: sending, by a base station, N signals and N pieces of physical random access channel PRACH resource indication information, where N is an integer greater than or equal to 2; and receiving, by the base station, a random access preamble sequence of the user equipment on PRACH resources indicated by the N pieces of PRACH resource indication information. Based on the foregoing solution, a quantity of random access preamble sequences sent by the user equipment is reduced, and uplink access complexity is reduced.

Abstract: Embodiments of the present invention provide a communication method, an apparatus, and a system. The method includes: generating, by a base station, first indication information, where the first indication information is used to indicate configuration information of a first resource; generating, by the base station, second indication information, where the second indication information is used to indicate a relationship between a second resource and the first resource to a terminal; and sending, by the base station, the first indication information and the second indication information, so that the terminal determines its own receiving resource or sending resource. When the base station indicates the receiving resource or the sending resource of the terminal, according to the technical solutions provided in the embodiments of the present invention, resource indication overheads can be reduced.
