Problems solved by technology

[0003] However, in the IAB scenario, when relay node A transmits signals in TDM mode and relay node B receives signals in SDM mode, and the distance between relay node A and relay node B is relatively close, the transmission of relay node A The signal will interfere with the transmitted signal of the relay node B, resulting in cross-link interference

Abstract

The embodiment of the invention discloses a signal transmission method applied to a relay technology and related equipment, which are used for realizing low-overhead cross-link interference management. The method provided by the embodiment of the invention comprises the following steps: a second node receives a first signal sent by a first node, wherein the first signal comprises information of time resources occupied by the first node during backhaul transmission and a transceiving state of the first node during backhaul transmission; and when the transceiving state of the first node during backhaul transmission is different from the transceiving state of the second node during backhaul transmission, the second node transmits and receives signals on resources except time resources occupied by the first node during backhaul transmission.

Description

technical field [0001] The present application relates to the field of wireless communication, and in particular to a signal transmission method applied to relay technology and related equipment. Background technique [0002] The long term evolution (long term evolution, LTE) LTE system introduces the relay technology (relaying). The relay technology deploys a relay node (relay node, RN) in the network to forward the base station (evolved node B, eNB) and The data between terminals (user equipment, UE) achieves the purpose of enhancing network capacity, solving backhaul connections between base stations, and solving coverage blind spots. figure 1 It is a possible network structure diagram, including a donor base station (donor eNB, DeNB), RN and UE. The RN is connected to the DeNB through a wireless interface, and the UE is connected to the RN or eNB through a wireless interface. The link between DeNB and RN is called backhaul link, and the link between RN and UE is called...
