Embodiment Construction
[0036] The basic idea of the present invention is: when processing the uplink coordinated data, after receiving the data signal of the user terminal from the base station, the coordinated data signal is first separated, and only the coordinated data signal is sent to the main base station, which greatly reduces the main and The amount of data transfer between base stations. When processing the coordinated data signal, the master and slave base stations cooperate with each other to obtain a good uplink cooperation gain.
[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings.

The invention discloses a method and a base station for processing uplink synergistic data in an orthogonal frequency division multiplexing system. The method comprises the following steps that: a synergistic user terminal sends an uplink data signal, a master base station and a slave base station receive the uplink data signal, the slave base station separates a synergistic user data signal from the received data signal of the user terminal and sends the synergistic user data signal to the master base station; the master base station judges whether the synergistic data signal from the slave base station is subjected to multi-antenna uncoiling or not; if so, the master base station merges the synergistic user data signal which is subjected to the multi-antenna uncoiling and is directly from the user terminal with the corresponding synergistic user data signal from the slave base station, and then performs demodulation and decoding; and otherwise, the master base station merges the synergistic user data signal which is directly from the user terminal with the synergistic user data signal from the slave base station, and then performs the multi-antenna uncoiling, demodulation and decoding. The invention simultaneously discloses the base station for processing the uplink synergistic data in the orthogonal frequency division multiplexing system. Through the method and the base station, good uplink synergistic gain can be acquired.
Description
technical field [0001] The invention relates to a method for processing uplink coordinated data in an Orthogonal Frequency Division Multiplexing (OFDM, Orthogonal Frequency Division Multiplexing) system and a base station used in the method for processing uplink coordinated data. Background technique [0002] With the requirement of Long Term Evolution Advanced (LTE-A, Long Term Evolution Advanced), people pay more and more attention to the average spectral efficiency of the cell and the spectral efficiency of the cell edge. In comparison, the spectral efficiency of the cell edge is the most concerned. This is mainly because the uplink and downlink of the LTE-A system is a frequency division system in which OFDM or a certain deformation of OFDM is used as the basic multiple access multiplexing method, which is different from the traditional code division multiple access (CDMA, Code Division Multiple Access) The wireless communication system of the basic multiple access multi...
