Problems solved by technology

However, when CoMP edge user pairing coordination needs to be dynamically controlled based on orthogonal resources in real time, a large number of calculations are required to achieve fast convergence, which not only increases the load on the system, but also increases the operator's equipment costs. s expenses

Embodiment Construction

[0037] Aiming at the technical problem in the prior art that a large amount of computing work must be performed each time resources are allocated, the present invention proposes a fast CoMP edge user pairing scheme based on ICIC edge user resource planning. When allocating edge user resources, ICIC Resource allocation is performed based on the planned orthogonal resources to reduce the resource allocation delay load of CoMP. like figure 2 As shown, it is a schematic flow chart of a resource allocation method proposed by the present invention, including the following steps:

[0038] S201. The MAC device receives and saves user information configured by the RRM device and a PRB pairing relationship table, where the PRB pairing relationship table includes a correspondence between each PRB group and its corresponding edge user.

[0039] In order to implement fast resource allocation on the MAC side, the RRM side first needs to prepare information through the following steps:

...

Abstract

The invention discloses a resource allocation method. On the basis of user information configured by radio resource management (RRM) equipment and a physical resource block (PRB) pairing relation table, media access control (MAC) equipment acquires the location of a user dispatched currently, then searches a PRB group corresponding to a cell-edge user, allocates the resource of the PRB group for the cell-edge user after confirming that the resource can be allocated for the cell-edge user according to the user pairing information of the PRB group, and updates the user pairing information. Through adoption of the method and device, MAC resource allocation of the cell-edge user can be rapidly finished, and the load of the system is lowered while the efficiency of MAC resource allocation and user pairing is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a resource allocation method. The present invention also relates to a MAC device and an RRM device. Background technique [0002] LTE (Long Term Evolution, long-term evolution) downlink adopts OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) technology, which basically solves the problem of intra-cell interference. But on the other hand, the problem of ICI (Inter-Cell Interference, inter-cell interference) existing therein is more serious than that of the CDMA (Code Division Multiple Access, Code Division Multiple Access) system. [0003] In order to coordinate the same-channel interference between cells, ICIC (Inter-Cell Interference Coordination, inter-cell interference coordination) technology and CoMP (Coordinated Multiple Points Transmission / Reception, multi-point coordinated transmission and reception) technology ...
