Problems solved by technology

like figure 2 As shown, the uplink load of RRU sector 1 is much greater than the uplink load of RRU sector 2, and the uplink signal coverage boundary is closer to the side of RRU sector 1, which is separated from the downlink signal coverage boundary position. If the moving UE When moving to the boundary of uplink signal coverage, RRU sector 2 also allocates corresponding downlink transmission power to the UE according to the strength of the uplink signal, and will allocate higher downlink transmission power, which leads to the utilization of downlink power of RRU sector 2. The efficiency is low, and the downlink performance of other UEs served by RRU sector 2 is degraded. In fact, the moving UE is located closer to RRU sector 1, and the downlink transmission power provided by RRU sector 1 is sufficient to support It works normally, the downlink transmission power boosted by RRU sector 2 is not only low in utilization, but also wastes the downlink power resource of RRU sector 2

[0047] In the first embodiment of the present invention, a method for finely allocating resources, such as image 3 shown, including the following specific steps:

[0048] Step S101, for any target RRU sector in a logical cell, compare the uplink signal quality of any UE for the target RRU sector with the uplink signal quality of the UE for the remaining RRU sectors in the logical cell Compare one by one to obtain the corresponding uplink signal quality difference; the logical cell is formed by merging two or more RRU sectors with equal pilot transmission power under one baseband processing unit; the target RRU sector is obtained from the logical cell Select from RRU sectors other than the RRU sector with the largest uplink load;

[0049] Specifically, the uplink signal quality value is reflected by the signal-to-interference ratio (SIR) of the uplink channel.

[0050] In step S101, the uplink signal quality of the UE for the target RRU sector is compared one by one with the...

[0058] The second embodiment of the present invention is a method for finely allocating resources. The method described in this embodiment is roughly the same as that in the first embodiment, the difference is that, as Figure 4 As shown, the method in this embodiment further includes the following specific steps before comparing the uplink signal quality one by one in step S101:

[0059] Step S100, in all RRU sectors in the logical cell, for any UE, detect the uplink signal quality of the UE for each RRU sector in the logical cell. The uplink signal quality can be used for comparison in step S101.

[0060] In all embodiments of the present invention, each RRU sector in a logical cell may be a macro RRU sector.

[0061] The third embodiment of the present invention is a method for finely allocating resources. The method described in this embodiment is roughly the same as that in the first embodiment, the difference is that, as Figure 5 As shown, the method in this embodiment also includes the following specific steps:

[0062] Step S103, since the target RRU sector and the corresponding neighbor RRU sector are required to calculate the difference in uplink signal quality, each uplink signal quality difference corresponds to a target RRU sector and a neighbor RRU sector, and for the set The neighbor RRU sectors corresponding to the difference in uplink signal quality of the condition allocate downlink coding resources and downlink power resources of each neighbor RRU sector to the UE.

[0063] Specifically, the uplink signal quality difference is the difference between the UE's uplink signal quality for the target RRU sector and the UE's uplink signal quality for the neighbor RRU secto...

Abstract

The invention provides a method and apparatus for precise resource allocation. The method comprises: for any target RRU sector in a logic cell, the uplink signal quality to the target RRU sector by any UE is compared with the uplink signal quality to the rest of RRU sectors in the logic cell by the UE one by one to obtain corresponding uplink signal quality differences, wherein the logic cell is formed by combination of more than two RRU sectors with the same pilot-frequency transmitting powers under a baseband processing unit and the target RRU sector is selected from RRU sectors except an RRU sector with the largest uplink load in the logic cell; and if at least one of the obtained uplink signal quality differences meets a set condition, only uplink demodulation resources of the target RRU sector are distributed to the UE. Therefore, the utilization efficiency of baseband resources and power resources of the base station can be improved.

Description

technical field [0001] The present invention relates to the field of WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) network technology, in particular to a method, device and BBU (Baseband Unit, baseband processing unit) for finely allocating resources. Background technique [0002] In the actual WCDMA commercial network, it is often possible to adopt a network deployment scheme that combines RRU (Radio Remote Unit, radio remote unit) cells corresponding to multiple radio frequency modules of the base station. A base station includes a BBU and several RRUs. One RRU covers one sector, so the sector covered by the RRU is called an RRU sector for short. Multiple RRU sectors are scrambled with the same downlink scrambling code, the situation of two RRU sectors is as follows figure 1 As shown, this can reduce inter-cell handover or reduce the workload of scrambling code resource planning, and save the configuration of baseband boards. The a...
