Abstract

A system, a method and a network equipment for realizing that one small zone covers a plurality of zone. The system is composed of a plurality of radio-frequency groups and at least one baseband unit; one radio-frequency group corresponds to one zone in one small zone, one radio-frequency group corresponds to one data channel, one baseband unit is connected with a plurality of radio-frequency groups through a plurality of data channel; the radio-frequency groups are used to receive the upward signal transmitted by the user equipment in the corresponding zone and to transmit the upward signal to the baseband unit through the corresponding data channel, the radio-frequency groups receive the upward signal in the corresponding data channel and transmit the downward signal to the user equipment in the corresponding zone; the baseband unit receives the upper signal transmitted by the radio-frequency group in the data channel and transmits the downward signal to the corresponding radio-frequency group through the corresponding data channel. The implementation method of the present invention reduces the signal interface among the different zones in one small zone, and improves the capacity of the system; moreover, the method is favor of the break-up of the small zone, and the upgrading and the expansion of the capacity during the network evolution.

Description

technical field

[0001] The invention relates to the technical field of network communication, in particular to a system, a method, a base station and a wireless network controller for realizing one cell covering multiple areas. Background technique

[0002] In the current communication system, one cell can cover multiple areas. Two main schemes for realizing cell coverage in multiple areas are introduced below.

[0003] Solution 1. Realize the coverage of multiple areas in the cell by means of base station + repeater. This solution is shown in Figure 1 and Figure 2 in the accompanying drawings.

[0004] In Figure 1, the three areas of Area C, Building A, and Building B belong to the same community. The near-end unit 1 and the far-end unit 1 form a repeater, and the near-end unit 2 and the remote unit 2 form another repeater, so that A and B in a cell are realized through the base station and the two repeaters. , C coverage of the three areas. Since the areas A, B, and C b...

Embodiment Construction

[0034] The system provided by the embodiments of the present invention for realizing coverage of multiple areas by one cell mainly includes: multiple radio frequency groups and at least one baseband unit. One baseband unit is connected to multiple radio frequency groups through multiple data channels, that is, one baseband unit corresponds to multiple data channels, and one baseband unit is connected to one radio frequency group through one data channel. The data channel here is used for information exchange between the radio frequency group and the baseband unit, and the data channel may include the antenna interface of the baseband unit, or the digital-to-analog conversion module between the radio frequency group and the baseband unit. The embodiment of the present invention does not limit the specific expression form of the data channel.

[0035] A radio frequency group in the embodiment of the present invention corresponds to an area in a cell, that is, a radio frequency g...
