Abstract: A time domain resource indication method includes sending, by a first node, first time domain resource configuration information to at least one second node. The first time domain resource configuration information is used by the at least one second node to determine second time domain resource configuration information sent by the at least one second node to at least one third node. The first time domain resource configuration information indicates first time domain resources of a link between the first node and the at least one second node. The second time domain resource configuration information indicates second time domain resources of a link between the at least one second node and the at least one third node.

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: A client device and a network access node engaged in downlink measurement information signaling and transmission in a communication system. The client device transmits a set of uplink reference signals and a feedback signal to the network access node. The feedback signal indicates measurement information about the downlink between the client device and a network access node. Based on the set of uplink reference signals and the feedback signal, the network access node determines a precoder and performs a downlink transmission of data/pilots to the client device using the precoder.
