Control channel information sending method and device based on common cell networking

Abstract

The invention discloses a control channel information sending method and a device based on common cell networking. The method comprising: obtaining uplink signal intensity information corresponding to each sector according to uplink signals sent by user equipment, wherein the sectors share the same cell identification, and the uplink signal intensity information represents the intensity of corresponding uplink signals; selecting the working sectors from all the sectors according to the uplink signal intensity information corresponding to each sector; and sending control channel information to the user equipment through the working sectors, and ordering the other sectors of all the sectors except the working sectors not to send the control channel information to the user equipment, so that in the common cell networking technology, when the sector in a cell sends signals, signal interference on a cell nonadjacent to the sector sending signals is prevented.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method and device for transmitting control channel information based on a common cell networking. Background technique [0002] With the development of the mobile Internet and smart terminals, the demand for the capacity of wireless networks has become higher and higher. The measures taken by the traditional expansion plan mainly include increasing the carrier of the system, or increasing the site, etc. Due to the limited network spectrum resources, the difficulty of obtaining site sites, and the high cost of new sites, the cost of the traditional expansion plan is too high. [0003] The coverage of the base station is generally determined by the coverage of the transmitted signal of the base station antenna. The traditional sector refers to the sector area covered by the beam transmitted by the base station antenna. Refer to figure 1 As shown, the coverage area of...

[0007] exist image 3 In this case, when sector 01 in cell0 transmits control channel information to user1, due to joint transmission, sector 00 of cell0 also transmits control channel information to user1, so cell2 will receive the signal transmitted by sector 00 of cell0 That is to say, although sector 00 of cell0 is not adjacent to cell2, but sector 00 of cell0 transmits signals to user equipment user1, it will still cause signal interference to cell2

Similarly, when sector 00 of cell0 transmits a signal to user0, sector 01 of cell0 will also transmit a signal to user0 due to joint transmission. Therefore, cell1 will be interfered by the signal transmitted by sector 01 of cell0, and also That is to say, although sector 01 of cell0 is not adjacent to cell1, sector 01 of cell0 transmits signals to user equipment user0, which still causes signal interference to cell1
