Abstract

A method of signaling system configuration information in a wireless mobile cellular communication system is disclosed. The method comprises transmitting the system configuration information at every predetermined period. In this case, each downlink subframe is divided into a plurality of frequency partitions, and subcarriers from at least two of the plurality of frequency partitions are allocated to a first mobile station using distributed resource allocation.

Description

technical field [0001] The present invention relates to a method for multiplexing distributed frequency resources and centralized (ie adjacent) frequency resources, especially for a wireless mobile cellular communication system adopting a fractional frequency reuse (FFR) scheme. Background technique [0002] Frequency Division Multiple Access or FDMA is a channel access method used in multiple access protocols that are channelization protocols. FDMA provides users with individual allocations of one or several frequency bands, allowing users to utilize the allocated radio spectrum without interfering with each other. A multiple-access system coordinates access among multiple users. Users may also share access via different methods, such as Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA) or Space Division Multiple Access (SDMA). These protocols are utilized differently at different layers of the theoretical OSI model. [0003] In the frequency dom...
