Embodiment Construction

[0084] As mentioned in the background technology, in the existing CBF scheme, the scheduling information on the subbands in each subframe needs to be transmitted to the cooperative cell for cooperative transmission. In a specific application scenario, especially for the X2 interface, there is a large resource overhead requirement, which affects the actual application effect of the network.

[0085] To solve the above problems, the pre-scheduling information can be transmitted between the base stations of the cells performing coordinated transmission, so that the corresponding base stations can perform coordinated scheduling / beamforming according to the pre-scheduling information.

[0086] Based on the above technical idea, the embodiment of the present invention proposes a method for spatial coordination between cells, which is applied to a mobile communication system including multiple cells, one of the multiple cells is the serving cell of the terminal, and other cells One o...

Abstract

The embodiment of the invention discloses a method and equipment for space coordination among cells, which ensure that pre-dispatch information can be transmitted among base stations of various cells for cooperative transmission and cooperative dispatching / wave beam forming can be carried out according the pre-dispatch information, thereby realizing the cooperative dispatching / wave beam forming by less information interaction and improving the frequency spectrum dispatching efficiency of the edge terminal of each cell.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for spatial coordination between cells. Background technique [0002] In the LTE-Advanced (Long Term Evolution Advanced, Advanced Long Term Evolution) system of the 3GPP, the multi-cell coordinated transmission technology will be used to improve the service quality of the cell edge users of the cell. [0003] ITU (International Telecommunications Union, International Telecommunication Union) put forward very strict requirements for the performance of the next generation mobile communication system IMT-Advanced (International Mobile Telecom System Advanced, advanced international mobile communication system), such as the maximum system transmission bandwidth of 100MHz, up and down The peak rate of row data transmission needs to reach 1Gbps and 500M bps. At the same time, very high requirements are put forward for the average spectral efficien...
