Embodiment Construction

[0051] The main idea of ​​the distributed control information sending method, receiving method and sending and receiving system of the present invention is to adopt control information classification, that is, the control information sent by the base station BS to the relay station RS is divided into first-level control information and second-level control information, and carries Different relay station identifiers are used to perform blind detection respectively.

[0052] sending method

[0053] The sending method of the distributed control information of the present invention is realized based on the base station BS, comprising the following steps:

[0054] Step 1, the base station BS generates relay station control information to be delivered to the covered relay station RS;

[0055] The relay station control information includes first-level control information and second-level control information, wherein the first-level control information is RS downlink scheduling gr...

Abstract

The invention provides a method and a system for transmitting and receiving centralized relay station control information. The transmission method is implemented based on a base station and comprises the following steps: (a) the base station generates the relay station control information which comprises the first-stage control information and the second-stage control information; (b) the base station carries a first relay station identifier on the first-stage control information and a second relay station identifier on the second-stage control information; and (c) the base station transmits the relay station control information processed by the step (b) to the relay station. The method and the system of the invention are well applicable to centralized scheduling, not only ensure that the relay station can receive the control information transmitted by the base station, and ensure 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 centralized relay station control information sending and receiving method and a transceiver 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 coverage on the o...
