METHODS FOR ALLOCATING RESOURCE IN LTE SYSTEM

Title:

METHODS FOR ALLOCATING RESOURCE IN LTE SYSTEM

Document Type and Number:

WIPO Patent Application WO/2010/134742

Kind Code:

A3

Abstract:

The present invention relates to a fractional RB (Resource Block) allocation method which enables resource allocation in a unit smaller than RB to improve the capacity of VoIP (Voice over Internet Protocol) in an LTE (Long Term Evolution) system. That is, the present invention introduces a resource arrangement method which allows different users to share the same resource, without even using an SDMA, and a method for informing the fractional RB allocation and how to use the same. A method for introducing multiplexation into an RB and changing the RE arrangement is proposed to support the downlink fractional RB allocation. A method for changing the RE arrangement is also proposed to support the uplink fractional RB allocation. According to the present invention, to provide a consistent service with a small amount of traffic generated as in the VoIP, resources of a smaller amount than a single RB can be used for a terminal with a good channel state. In the present invention, the occupancy of resources for the terminals of an excellent channel state is reduced so that the capacity of the VoIP can be improved.
