Description

A kind of maximum transmission power method to set up, equipment and system based on RRU

Technical field

The present invention is about wireless communication technology field, particularly about the time-division synchronous-code division multiple access (TD-SCDMA, time-division synchronous code division multiple access) moving communicating field, is a kind of maximum transmission power method to set up, equipment and system based on RRU concretely.

Background technology

Existing TD-SCDMA network is when planning, and unification is set to macro base station, uses 8 passage Remote Radio Unit unit (RRU, Radio remote unit), and each community is set to 3 carrier waves.In 3 carrier waves of each plot planning, 1 is R4 (3GPP Release4 agreement) carrier wave, as cell main carrier, and main carrier signaling message, speech business and part small amount data business.Other 2 is support fast grouping downlink data access function (HSDPA, High Speed Downlink Packet Access) carrier wave, and every HSDPA carrier wave arranges 3 HSDPA time slots.The single-code channel transmitting power unification of the Primary Common Control Physical Channel of all macro base stations community (PCCPCH, Primary Common Control Physical Channel) is configured to 30dBm.There are the following problems in the above-mentioned setting of existing TD-SCDMA network:

(1), whole net utilance is not high, but there is network congestion phenomenon in part.

Existing TD-SCDMA network using unified setting, the traffic hotspots region of therefore waiting TD-SCDMA in such as urban district, single subdistrict 3 carrier waves of configuration can not meet user's normal demand, are difficult to reach continuous covering, have reduced user's experience.And in the very little region of traffic carrying capacity of TD-SCDMA such as city's area edge and rural area, configure 3 carrier waves and will waste power resource.

(2), the power configuration of common signal channel and Traffic Channel does not reach maximum.

Current TD-SCDMA system is a code power limited system, the PCCPCH of community is that to decide ，Er community maximum transmission power be that power with reference to RRU calculates for the shared code channel of signaling channel that is distributed in main carrier TS0 time slot according to community maximum transmission power.Take RRU single channel 2W(33dBm) be example, 8 passages can with equipment gross power be 33+10*log(8)=42dBm, the equipment gross power of each community of macro base station is 42dBm.For N frequency TD network, common signal channel is carried on main carrier, and main carrier TS0 time slot is provided with 6 common signal channels, and main carrier TS0 available horsepower is 42dBm, and several carrier wave gross powers of Traffic Channel are 42dBm.PCCPCH single-code channel can with maximum power be 42-10*log(6)=34.2dBm, the power in PCCPCH dicode road is 34.2+3=37.2dBm.And the power in PCCPCH dicode road is defaulted as 33dBm at present, single-code channel is 30dBm.

It is upper that Traffic Channel is carried on TS1-TS6, and the available maximum power of each carrier wave is 42-10*log(n), wherein n is carrier number.According to the collocation method of existing each 3 carrier wave in macro base station community, the maximum power of each carrier wave is: 42-10*log(3)=37.2dBm.The single carrier maximum transmission power of the current default setting of TD network is 33.9dBm.

The transmitting power of the common signal channel under the unified configuration of existing TD-SCDMA network and Traffic Channel does not reach maximum, thereby in the region of TD network coverage deficiency, will inevitably reduce user's use impression.
