Abstract
A dynamic resource allocation method and apparatus for broadband services in a wireless communications system. The communications system can have a number of cells, each of which has multiple sectors. Each sector can contain a number of communications sites. Information is transmitted in time subframes scheduled to avoid interference between the sectors and cells, and different degrees of concurrent packet transmission can be scheduled for different classes of communications sites. The communications sites can be classified based on reception quality, such as by comparing their measured signal-to-interference ratio (SIR) with a SIR threshold.
Claims36
A method for operating a communications system having a plurality of communications sites and a service area divided into a plurality of sectors, the communications system using a plurality of time subframes scheduled to avoid interference between the plurality of sectors, each subframe being further divided into a plurality of mini-frames, comprising the steps of:
- scheduling a first degree of concurrent packet transmissions in a first mini-frame for a first class of communications sites located within each sector;
- scheduling a second degree of concurrent packet transmissions in a second mini-frame for a second class of communications sites located within each sector, the second degree being different from the first degree;
- and
- communicating said packets according to said scheduling.
A communications system having a plurality of communications sites and a service area divided into a plurality of sectors, the communications system using a plurality of time subframes scheduled to avoid interference between the plurality of sectors, comprising:
- a first class of communications units operably associated with the service area for communicating between the communications sites using at least one time subframe;
- a second class of communications units operably associated with the service area for communicating between the communications sites using at least one time subframe;
- a scheduler for scheduling a first degree of concurrent packet communications for the first class of communications sites and scheduling a second degree of concurrent packet communications for the second class of communications sites, the second degree being different from the first degree.
