Embodiment Construction

[0027] In order to solve the problems existing in the prior art, an embodiment of the present invention proposes a resource allocation method for subframes in the same direction. A basic concept—subframe type is defined. This embodiment includes two subframe types: non-resource-restricted subframe (also called soft subframe) and resource-restricted subframe (also called hard subframe). Among them, a soft subframe refers to a subframe with unlimited resource utilization; a hard subframe refers to a subframe with limited resource utilization. The resource utilization of a hard subframe cannot exceed a certain resource utilization threshold. The utilization threshold is generally less than 1. It should be pointed out that any soft subframe of each cell and any soft subframe of its neighboring cells should be staggered from each other. In this scheme, when allocating resources to a group of co-direction subframes with the same data transmission direction in the cell, for each cur...

Abstract

The invention relates to the technical field of mobile communication, in particular to a technology for resource distribution among homodromous subframes. The invention also discloses a method for resource distribution among homodromous subframes, which is used for solving the problem that heavier subframe load and larger same frequency interference to an adjacent district are easily caused when data is transmitted in the subframes. The method comprises the following steps: confirming the types of the subframes in one group of homodromous subframes with same data transmission direction in thedistrict according to the serial number of the current subframe; confirming the threshold value of the resource utilization ratio of the current subframe according to the actual resource utilization ratio of the former homodromous subframe adjacent to the current subframe and the residue data size for ensuring bit rate service when the subframe is a resource limited subframe; and distributing resources for transmitting data in the current subframe and ensuring that the distributed actual resource utilization ratio does not exceed the threshold value of the resource utilization ratio. The invention also provides a device and a based for resource distribution among homodromous subframes.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a resource allocation technology between subframes in the same direction. Background technique [0002] The LTE (Long Term Evolution, long-term evolution) system is a multi-carrier system in which the physical layer adopts OFDM (Orthogonal Frequency Division Multiplex) technology. Several subcarriers form a resource block, and the resource block is used as a unit for scheduling. The current research on the LTE physical layer technology mainly focuses on two duplex modes: FDD (Frequency Division Duplex, frequency division duplex) and TDD (Time Division Duplex, time division duplex). [0003] For the LTE FDD system, uplink and downlink data occupy different frequency bands, and uplink and downlink data can be transmitted simultaneously. For the LTE TDD system, the uplink and downlink data occupy the same frequency band, and the uplink and downlink data can onl...
