Embodiment 1

[0028] A resource allocation method for coordinated multi-point CoMP mode, see figure 1 , the method includes the following steps:

[0029] 101: Receive measurement information of a user equipment UE in an overlapping area of ​​multiple cells;

[0030] 102: Determine each optional CoMP mode of the UE on each optional time-frequency block according to the measurement information of the UE;

[0031] 103: Determine the data rate and rate when the UE adopts each optional CoMP manner on each optional time-frequency block.

[0032] 104: According to the data rate and rate when the UE adopts the optional CoMP methods on the optional time-frequency blocks and adopts the optional CoMP methods on the optional time-frequency blocks, Perform resource allocation for the UE.

[0033] The beneficial effect brought by the technical solution provided by the embodiment of the present invention is: the beneficial effect brought by the technical solution provided by the embodiment of the prese...

Embodiment 2

[0035] see figure 2 , an embodiment of the present invention provides a resource allocation method for coordinated multi-point CoMP. In this embodiment, i user equipment UEs (the i The serving cell of a UE is cell 1 or cell 2) as an example, and an optional time-frequency block and an optional CoMP mode are allocated to the i UEs, where i is the number of user equipments (UEs) in the overlapping area.

[0036] Step 201: Receive measurement information of each user equipment UE to be allocated resources in the overlapping cell:

[0037] The serving cell sends the time-frequency position and bandwidth of the available time-frequency blocks that can be used in the CoMP mode in the overlapping area, and the transmit power information of the serving cell on these time-frequency blocks to UEs belonging to the serving cell in the overlapping area, that is, Cell 1 sends the above information to UEs belonging to cell 1, and cell 2 sends the above information to UEs belonging to cell ...

Embodiment 3

[0130] The above-mentioned steps of allocating an available time-frequency block and an optional CoMP mode on the available time-frequency block to the UE to be allocated resources can be completed by a coloring method.

[0131] see Figure 7 , the optional CoMP method on the available time-frequency block of the UE to be allocated resources is defined as CoMP i，x : where i corresponds to the UE in the overlapping area, modulo x to 3, the obtained quotient is the available time-frequency block number of UE(i), and modulo x to 3, the remainder corresponds to the optional CoMP mode, and the remainder is 1 corresponds to the CBF method, a remainder of 2 corresponds to the Coherent JP method, a remainder of 3 corresponds to the Non-Coherent JP method, and x corresponds to Col(x), that is, each X corresponds to a color, that is, CoMP I，x Corresponds to Col I，x .

[0132] In this example, assuming that there are 5 available time-frequency blocks (time-frequency blocks 0, 1, 2, 3,...

Abstract

The invention discloses a resource allocation method for a coordinated multiple point (CoMP) mode and a base station, belonging to the communication technical field. The method comprises the following steps: receiving measurement information of various user equipment (UE) for which resources are to be allocated in an overlay cell; determining the optional CoMP modes on available time-frequency blocks of the UE and corresponding data rate and degree according to the measurement information; and carrying out resource allocation for the UE according to the optional CoMP mode on the available time-frequency blocks of the UE and the corresponding data rate and the degree. The invention further discloses a base station. The invention solves the problem of allocating time-frequency resources andthe CoMP mode for users, and can meet the data rate requirement for each user maximally and maximize system optimization objectives. When the amount of the available time-frequency blocks is obviously less than that of the UE, performances are greatly improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a resource allocation method and a base station for a CoMP (Coordinative Multiple Point, coordinated multi-point) mode. Background technique [0002] In modern communication systems, such as LTE-A (Long Term Evolution Advanced, further long-term evolution) system, the communication process between edge users and serving cells is severely interfered by neighboring cells, which cannot meet the communication needs of users. In order to solve this problem, the proposed Coordinated Multiple Point transmission and reception (CoMP for short) technology is proposed, that is, each neighboring cell cooperates with each other to jointly serve a terminal UE (User Equipment) or multiple UEs. [0003] The CoMP methods supported by LTE-A mainly include: CBF (Coordinative Beam Form, coordinated beam forming), Coherent JP (Coherent Join Process, correlated joint processing) and Non...
