Problems solved by technology

[0007] Embodiments of the present invention provide a method, system, and device for determining a cell participating in CoMP transmission and transmitting data, to solve the problem existing in the prior art that the serving cell requires the coordinated cell to process the coordinated data regardless of the current state of the coordinated cell. There is a situation that the determined coordinated cell cannot perform coordinated transmission, thereby reducing the performance of the CoMP technology

Embodiment Construction

[0042] In the embodiment of the present invention, after the base station to which the coordinated cell belongs satisfies the trigger condition, it determines the coordinated transmission parameter according to the coordinated transmission capability of the coordinated cell, and sends the coordinated transmission parameter to the base station to which the serving cell belongs; the base station to which the serving cell belongs parameter, and determine the coordinated cells participating in the CoMP transmission from the coordinated cells. Because the base station where the serving cell is located will determine the corresponding coordinated cell according to the current coordinated transmission capability of the coordinated cell, avoiding the situation that the determined coordinated cell that can participate in CoMP transmission cannot perform coordinated transmission due to insufficient capabilities, thereby improving the CoMP technology. performance.

Abstract

The invention relates to a wireless communication technology, specifically to a method, system and device for determining joining CoMP transmission cell and transmission data, so as to solve the problem that the service cell in the prior art requires the collaborative cell to join the collaborative transmission regardless the current status of the collaborative cell, and perhaps, the determined collaborative cell cannot do collaborative transmission, so that the technical performance of CoMP is reduced. The method for determining joining CoMP transmission cell in the embodiment of the invention comprises the following steps: determining the collaborative transmission parameter according to the collaborative transmission ability after the base station where the collaborative cell belongs meets the trigger condition; determining the collaborative cell for joining the CoMP transmission from the collaborative cells by the base station where the collaborative cell belongs, according to thereceived collaborative transmission parameter. By adopting the method, the invention can improve the performance of the CoMP technology.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method, system and device for determining a cell participating in a CoMP (Coordinated multi-point, coordinated multi-point) transmission and transmitting data. Background technique [0002] ITU (International Telecommunication Union, International Telecommunication Union) has put forward very strict requirements for the performance of the next-generation mobile communication system IMT-Advanced, that is, the maximum system transmission bandwidth must reach 100MHz, and the peak rate of uplink and downlink data transmission must reach 500Mbps and 1Gbps respectively. . In order to meet the requirements of the new IMT-Advanced system, 3GPP proposed in its next-generation mobile cellular communication system LTE-Advanced that Coordinated Multipoint Transmission (CoMP) technology be used to improve system performance. [0003] The CoMP technology refers to multiple geogra...
