Problems solved by technology

Each cell uses the same frequency band, and the overall frequency utilization rate is high, but the inter-cell interference is relatively large, especially the edge users are seriously interfered, and ICIC (Inter-Cell Interference Coordination) must be combined to suppress interference and optimize the network

Embodiment Construction

[0044] In order to solve the problems existing in the prior art, a cell bandwidth configuration method proposed by an embodiment of the present invention defines a set of cells that are close together as a cell cluster, and divides the total available bandwidth into multiple subsets, wherein, The bandwidths of any two subsets may partially overlap or not overlap at all. After the allocation is completed, each subset is allocated to multiple cells in a cell cluster.

[0045] This flexible cell frequency planning solution is applicable to any wide system bandwidth. In the allocation of frequency resources, the natural isolation of resources can be used, and each cell preferentially uses its own or relatively exclusive frequency band resources; when the load is heavy, Each cell can use its allocated bandwidth. At this time, it can be considered to allocate "exclusive" frequency bands to cell edge users who need high power to avoid interference.

[0046] This method is flexible on...

Abstract

The embodiment of the invention discloses a method and device for configuring the cell bandwidth, which can be used to flexibly plan the system bandwidth of each cell and suitable for frequency spectrum resources with any width. Natural isolation of the resources is utilized to allocate frequency resources, thus each cell can use own exclusive or relatively exclusive frequency resources preferentially.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a cell bandwidth configuration method and device. Background technique [0002] TD-LTE (Time Division-Synchronous Code Division Multiple Access LongTerm Evolution, the long-term evolution of Time Division Synchronous Code Division Multiple Access), as an advanced technology, requires the system to increase the peak data rate, cell edge rate, spectrum utilization, and focus on To further improve the cost of operation and network construction, and to enable users to obtain an "Always Online (always online)" experience, it is necessary to reduce the delay of the control and user planes. The system must be able to coexist with existing systems (2G / 2.5G / 3G). [0003] To do this, the existing system needs to change in a number of ways: [0004] On the radio access network (Radio Access Network, RAN) side, the CDMA technology will be changed to a...
