Communication method and equipment

Abstract

The embodiment of the invention provides a communication method, communication equipment, a communication device and a baseband unit BBU. The communication equipment comprises the BBU and a remote radio unit RRU having n physical antennas; the BBU and the RRU are connected through an optical fibre; n is 1 or 2; the BBU is used for obtaining four-path signals, generating a baseband digital signal according to at least two-path signals in the four-path signals, and sending the baseband digital signal to the RRU through the optical fibre, wherein the four-path signals and four logic ports of the BBU are in one-to-one correspondence; and the RRU is used for converting the baseband digital signal into a radio-frequency signal, and transmitting the radio-frequency signal through the n physical antennas. By means of the embodiment of the invention, the cell capacity and the signal quality can be increased.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, relates to a communication method and equipment used in a cell merging system. Background technique [0002] At present, a research hotspot of the Long Term Evolution (LTE) network is how to combine the coverage areas of different types (such as single channel, multi-channel, etc.) of the Radio Remote Unit (RRU), so that Improve cell coverage and improve signal quality. For example, N1-channel RRUs and N2-channel RRUs are used to form a network. This networking may be referred to as N1+N2 combination for short, and this scenario may also be called N1+N2 cell combination. In another example, N1 channel RRUs, N2 channel RRUs and N3 channel RRUs are used to form a network. This networking can be referred to as N1+N2+N3 combination for short, and this scenario can also be called N1+N2+N3 cell combination. For another example, if N1-channel RRU, N2-channel RRU, N3-channel RRU...
