Title:
METHOD AND DEVICE FOR CONTROLLING TRANSMISSION DELAY IN A COORDINATED MULTI-POINT TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/105556
Kind Code:
A1
Abstract:
The invention provides a method and a device for controlling transmission delay in a base station of a wireless communication system based on coordinated multi-point transmission. Specifically, while the base station sends downlink data to a mobile terminal, it transforms a part of data of one or more other non-synchronous base stations and then sends it to said mobile terminal in one or more specific time slots. After applying the solution of the invention, as the data of the non-synchronous base station corresponding to the length of the loss of synchronization information is sent to the mobile terminal in the specific time slots by the synchronous base station or other non-synchronous base stations, the downlink data sent by the non-synchronous base station to the mobile station all falls in the detection window of the mobile terminal, thereby solving the problem of receiver performance degradation caused by the transmission delay.
