Embodiment Construction

[0032] In order to provide a context for embodiments of the invention for use in a communication system, figure 1 A base station controller (BSC) 10 is shown which controls wireless communications in a plurality of cells 12 served by respective base stations (BS) 14 . Typically, each base station 14 facilitates communications using OFDM using a Mobile Subscriber Station (MMS), also referred to as a mobile and / or wireless terminal 16 , located within the cell 12 associated with the respective base station 14 . The movement of the mobile terminal 16 relative to the base station 14 is known to cause large fluctuations in channel conditions. As shown, base stations 14 and mobile terminals 16 may include multiple antennas to provide space diversity for communications.

[0033] Before delving into the structural and functional details of the preferred embodiment, a high-level introduction to the mobile terminal 16 and base station 14 on which aspects of the present invention will b...

Abstract

A channel descriptor management message is transmitted on a broadcast connection to a mobile terminal. The channel descriptor management message provides a format for a frame. The frame includes a resource space. The channel descriptor management message defines a plurality of channels within the resource space and allocates at least one of the channels to a plurality of users. Subsequent resource allocation messages may refer to a location within a channel rather than a location within the entire resource space.

Description

[0001] This application is a divisional application of the invention patent application with the application number 200580041149.3, the application date is October 17, 2005, and the invention name is "communication resource allocation system and method". technical field [0002] The present invention relates to wireless communications, and more particularly to methods of allocating communication resources among a plurality of users. Background technique [0003] In communication transport interfaces using dynamic resource sharing, it is common for a resource management entity to schedule resource usage among one or more end users during each of a sequence of scheduling intervals. The resources to be shared may be, for example, time, code, frequency, antenna, etc., or their combination (multi-dimensional resources). For allocating multi-dimensional resources, the allocation of resources to each dimension is indicated. [0004] In cases where the resource space is large, eg, ...
