Abstract

The invention provides a method for transmission and indication of a relay system, comprising the following steps: a base station transmits indication information to a terminal for indicating frequency band resource information transmitted by relay downlink backhaul in a special region; the base station transmits a scheduling signaling transmitted by downlink data to the terminal; and the base station transmits the downlink data to the terminal on corresponding frequency band resources. In the technical scheme provided by the invention, through allocating and indicating a relay downlink backhaul linkage which does not occupy all reserved resources, a problem of utilizing unoccupied resources in downlink backhaul linkage resources of a relay is solved, and the downlink resources are fully adopted to provide service for a user.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular, the present invention relates to a method and device for transmission and indication of a relay system. Background technique [0002] Mobile and broadband have become the development direction of modern communication technology. 3GPP (3rd Generation Partnership Project) is committed to the evolution of LTE (Long Term Evolution, long-term evolution) system as a 3G system, with the goal of developing 3GPP wireless access Technology is evolving towards high data rates, low latency, and optimized packet data applications. In future mobile communication systems, such as B3G (Beyond three Generation) or LTE-A, the system will provide higher peak data rate and cell data throughput, so the system also needs wider transmission bandwidth. At present, there are very few unallocated radio frequency resources below 2GHz, and part or all of the bandwidth required by the B3G system ...
