Communication resource allocation systems and methods

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. This is achieved with resource allocation maps and sub-maps (nested MAP's).

Description

technical field [0001] The present invention relates to wireless communications, and more particularly to methods of allocating communication resources among a plurality of users. Background technique [0002] 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. [0003] In cases where the resource space is large, eg, broadband systems including multiple antennas (in which only relatively small resource granularity can be accommodated), resource allocation is known to incur considerable overhead. Such an exemplary multiple-antenna system is known as a Multiple-Input Mul...
