Embodiment 1

[0059] In this example, set as Figure 4 The structure shown specifically includes the following modules, and lists the functions of each module:

[0060] Pre-scheduling module: The original system needs to be modified to increase the pre-allocation function of air interface resources;

[0061] Uplink channel data receiving module: responsible for receiving channel measurement data transmitted by UE through the air interface;

[0062] Downlink precoding module: modify the original system to add dynamic precoding function;

[0063] COMP module: a new module to maintain the UE coordination set, resource coordination set, precoding matrix W calculation, and exchange information such as resources, channels, time, and precoding with adjacent stations.

[0064] Uplink channel feedback module: complete the feedback of the interference channel;

[0065] Channel measurement module: complete the channel measurement of the service station and interference station;

[0066] Based on t...

Embodiment 2

[0086] see Figure 5 The scene diagram of the implementation shown, wherein,

[0087] There are two sectors CELLb and CELLc under NB2;

[0088] There is a sector of CELLa under NB1;

[0089] UEa's current serving cell is CELLa, which is at the boundary of CELLa and CELLb, so it can receive the interference signal of CELLb;

[0090] UEb's current serving cell is CELLb; it is at the boundary of CELLb and CELLc, so it can receive the interference signal of CELLc;

[0091] The current serving cell of UEc is CELLc, which is located at the boundaries of CELLa, CELLb, and CELLc, and therefore can receive interference signals from CELLb and CELLa.

[0092] It is assumed that the resources allocated by the three UEs overlap, and if there is no overlap, the precoding matrix does not need to be changed, and the processing is still carried out in the manner mentioned in the related art.

[0093] Specific collaboration methods such as Figure 6 shown, including:

[0094] Step S602, UEa...

Abstract

Disclosed are a base station cooperation method and system. The method comprises: a base station initiating cooperation determining a resource to be allocated to a UE; and other base stations in a COMP set than the base station initiating cooperation selecting, through cooperation, a UE suitable for the resource from UEs managed by the other base stations, the COMP set comprising all base stations capable of allocating resources. Through the present invention, no priority constraint exists in the cooperation initiation condition, thereby effectively increasing the cooperation opportunities.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a base station cooperation method and device. Background technique [0002] As the standard of the fourth-generation communication system (4G), IMT-Advanced (Intelligent Multimode Terminal-Advanced, improved intelligent multi-mode terminal) puts forward higher requirements for system performance, especially for the frequency efficiency of uplink and downlink. requirements. [0003] COMP (Coordinated multi-pointtransmission / reception, coordinated multi-point transmission) is a technology that can expand the rate transmission coverage, improve the service quality and throughput of the cell edge, and the system throughput. As an important technology to improve the system spectrum utilization, has received widespread attention. The so-called coordinated multi-point transmission means that multiple base stations coordinate transmission to serve one or more UEs (User Equipment, use...
