SIGNAL TRANSMITTING METHOD AND BASE STATION DEVICE

摘要

The present invention provides a signal transmitting method and a base station device. The signal transmitting method is applied to a base station device including a time domain exchanging module and a baseband processing unit, where the time domain exchanging module is connected to the baseband processing unit. The method includes: receiving, by the time domain exchanging module, a first time domain signal transmitted by a user equipment through a radio frequency channel of a serving cell of the user equipment, and receiving a second time domain signal transmitted by the user equipment through a radio frequency channel of a coordinating cell of the user equipment; and transmitting the first time domain signal and the second time domain signal to the baseband processing unit, which is corresponding to the serving cell of the user equipment. Through the present invention, CoMP data exchange can be implemented in an LTE-A system.

1. A base station device, applied to a communication system, in which at least two cells cooperatively participate in data transmission or reception of a user equipment (UE) and the at least two cells comprise a serving cell of the UE and at least one coordinating cell of the UE, wherein the base station device comprises:
a baseband processing unit corresponding to the serving cell; and a time domain exchanging module connected with the baseband processing unit, wherein the time domain exchanging module is configured to receive a first time domain signal transmitted by the UE through a radio frequency channel of the serving cell, and receive a second time domain signal transmitted by the UE through a radio frequency channel of each coordinating cell; and transmit the first time domain signal and the second time domain signal to the baseband processing unit; and the baseband processing unit is configured to receive the first time domain signal and the second time domain signal, perform time-frequency transformation and demapping on the first time domain signal and the second time domain signal to obtain frequency domain signals of the UE in the serving cell and each coordinating cell, and jointly process the frequency domain signals of the UE.
