Control information sending and receiving method of distributed relay station and transceiving system

Abstract

The invention provides a control information sending and receiving method of a distributed relay station and a transceiving system, wherein the sending method is realized based on a base station. The control information sending and receiving method comprises the steps that: (1) the base station generates relay station control information which comprises the first stage of control information and the second stage of control information; (2) the base station enables the first stage of control information to bear a first identification of the relay station and enables the second stage of control information to bear a second identification of the relay station; and (3) the base station sends the relay control information processed by the step (2) to the relay station. The method and the system can better adapt to the distributed dispatching and not only ensures the relay station can receive the control information assigned by the base station but also ensures the backward compatibility.

Description

technical field [0001] The present invention relates to OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) technology, in particular to a distributed relay station control information sending and receiving method and a sending and receiving system. Background technique [0002] At present, the goal of a new generation of wireless communication networks is to integrate access systems such as cellular, fixed wireless access, nomadic, and wireless area networks, and combine with an all-IP network to provide users with a peak rate of 100 Mbps and 1Gbps wireless transmission capability. In order to achieve this goal, the wireless communication network needs to provide services to users in a wide range of high-band spectrum. Due to the wireless propagation characteristics of electromagnetic waves, wireless communication systems operating at high frequencies can obtain high capacity on the one hand, but are also limited by limited coverag...

Problems solved by technology

[0022] At present, the research on resource allocation and cooperation between BS and RS is a hot spot, but there is less research on the control information transmission of distributed RS introduced into the network. Distributed RS can generate control signaling, and the control signaling of UEs covered by it It comes from the UEs issued by the RS to its coverage, so how to ensure that the RS can receive the control information issued by the BS and ensure backward compatibility, and this is exactly the problem to be solved by this invention
