Embodiment Construction

[0078] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0079] BBs in a communication system can generally be divided into uplink BB processing and downlink BB processing. Uplink BB processing such as Figure 4 As shown, it usually includes a demodulation function module 403 and a decoding function module 401; the downlink BB processing is as follows Figure 5 As shown, generally includes an encoding function module 501 and a modulation function module 503 . In addition, in some communication systems, the downlink BB processing also includes: a spreading (Spreading) functional module, and the uplink BB processing also includes a despreading (Despreading) functional module. It should be noted that in each embodiment of the technology of the present invention, unless otherwise specified, the functional modules including one or more functions of encoding, decod...

Abstract

A communication system, a communication interface, and a communication method are disclosed. The communication system includes a first field replaceable unit (FRU) and a second FRU. The first FRU includes: a radio frequency / intermediate frequency (RF / IF) module, adapted to perform conversion between an RF signal and a base band (BB) signal; and a first BB module, adapted to process the first part of BB signals according to a preset configuration rule for processing data. The second FRU includes: a second BB module, adapted to process BB signals other than the first part of BB signals according to the preset configuration rule for processing data. With the present invention, the BB may be split into two parts. One part of the BB may be integrated with the RF module, and the other part may be an independent physical entity.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication system, a communication interface and a communication method. Background technique [0002] A base station system logic architecture such as figure 1 As shown, including transmission module 107, main control module 112, BB (BaseBand, baseband) module 105, radio frequency intermediate frequency (RF / IF) module 101 and interface (first interface 103, second interface 109), etc., the base station system is further connected with Network controller communication. On the uplink channel, under the control of the main control module, the signal from the air interface is processed by the RF / IF module, such as: RF filter amplification, frequency down conversion, analog-to-digital conversion, digital filter, etc., and becomes a baseband signal, and then passes through the BB module Baseband processing, such as demodulation and decoding, finally transmits the informat...
