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 at least one baseband processing unit, where the time domain exchanging module is respectively connected to the at least one baseband processing unit. The method includes: receiving, by the time domain exchanging module, a first time domain signal transmitted by a first user equipment through a radio frequency channel of a serving cell of the first user equipment, and receiving a second time domain signal transmitted by the first user equipment through a radio frequency channel of at least one coordinating cell of the first user equipment; and transmitting, by the time domain exchanging module, the first time domain signal and the second time domain signal to a baseband processing unit corresponding to the serving cell of the first user equipment in the at least one baseband processing unit. Through the present invention, CoMP data exchange can be implemented in an LTE-A system.
Description
technical field [0001] The present invention relates to communication technology, in particular to a signal sending method and base station equipment. Background technique [0002] In the Long Term Evolution-Advanced (hereinafter referred to as: LTE-A) system, the coordinated multi-point transmission / reception (Coordinated Multi-point Transmission / Reception; hereinafter referred to as: CoMP) technology can be used to increase the coverage of high data rates and improve the throughput and / or increase system throughput. The so-called CoMP refers to a plurality of geographically separated transmission points (which can be understood as different cells) cooperatively participating in transmitting or receiving data to a user equipment (User Equipment; UE for short). [0003] CoMP can be divided into downlink CoMP and uplink CoMP. Downlink CoMP means that multiple cells directly or indirectly participate in the downlink data transmission of the same UE; uplink CoMP means that mul...
