Abstract

The embodiment of the invention discloses a method for transmitting pilot signals and a relay node. The method comprises the following steps: if sending of a first pilot signal conflicts with receiving of a second pilot signal, determining priorities of first configuration information and second configuration information; the first configuration information being used for configuring a sending moment of the first pilot signal, the second configuration information being used for configuring a receiving moment of the second pilot signal, the first pilot signal being received by the relay node, and the second pilot signal being received by terminal equipment; and executing pilot signal transmission operation matched with a priority determining result. According to the method provided by the embodiment of the invention, the problem that the accuracy of pilot signal measurement of the relay node and the terminal equipment is influenced by sending and receiving conflicts of the pilot signalscan be avoided, and the communication effectiveness is improved.

Description

technical field [0001] The present application relates to the technical field of communication, and more specifically relates to a method for transmitting a pilot signal and a relay node. Background technique [0002] The relay (Relay) technology in the wireless communication system adds one or more relay nodes between the network device and the terminal device, which is responsible for one or more forwarding of the wireless signal, that is, the wireless signal needs to go through multiple hops to to the end device. figure 1 A 4-hop wireless relay link is shown. figure 1 The medium signal is forwarded by three relay nodes from the donor (Donor) base station to the terminal equipment (User Equipment, UE). [0003] In a wireless communication system where a relay node is set up, there will be two kinds of measurement configuration information at the same time, one is used for the terminal equipment to measure the pilot signal, and the other is used for the relay node to meas...
