Abstract

The present invention is a communication system having a plurality of forward channel communications and a plurality of corresponding reverse channel communications in a region for communications with cellular users. Each region includes a plurality of zone managers. Each zone manager includes a broadcaster having a broadcaster transmitter for broadcasting a plurality of forward channel communications using broadband broadcaster signals to form a plurality of broadcaster forward channels. Each zone manager includes an aggregator for processing reverse channel communications. Each zone manager communicates with a collector group for receiving reverse channel communications from users and forwarding reverse channel communications to the aggregator. Each of the users includes a user receiver for receiving a different forward channel from said broadcaster and includes user transmitter means for broadcasting user reverse channel communications in a different user reverse channel. The collector group for each zone manager is formed of macro-diverse collectors some of which are located at other zone managers. By having collectors co-sited at zone manager sites, the macro-diverse collector operations are possible while reducing the installation cost of collectors

Claims

1. A communication system having a plurality of forward channel communications and a plurality of corresponding reverse channel communications comprising,

a region manager means for communicating said plurality of forward channel communications and a plurality of corresponding reverse channel communications in a region,

a plurality of zone manager means in said region each including,

broadcaster means having a broadcaster transmitter for broadcasting said plurality of forward channel communications using broadband broadcaster signals to form a plurality of broadcaster forward channels,

aggregator means for processing reverse channel communications,

collector means for receiving reverse channel communications and forwarding reverse channel communications to said aggregator means,

a plurality of users,

each of said users including user receiver means for receiving a different forward channel from said broadcaster means and including user transmitter means for broadcasting user reverse channel communications in a different user reverse channel,

the improvement characterized by:

said broadcaster means broadcasting said plurality of broadcaster forward channels in a broadcaster zone,

said plurality of users, located in said broadcaster zone, for providing a plurality of different user reverse channels collectively as a broadband composite signal,

a plurality of said collector means distributed over said broadcaster zone at macro-diverse locations so that each of said plurality of collector means is active to receive said composite signal over at least a portion of said broadcaster zone and so that user reverse channels for some ones of said plurality of users are received by two or more of said collector means,

each of said collector means including broadband collector receiver means for receiving said broadband composite signal with reverse channel communications from ones of said plurality of users, and

each of said collector means including collector forwarding means for forwarding, to said aggregator means, said user reverse channel communications from said ones of said plurality of users as collector reverse channel communications,

said aggregator means for receiving said collector reverse channel communications from said collector means to provide said corresponding reverse channel communications for each of said ones of said plurality of users as a combination of the collector reverse channel communications from said two or more collector means.

2. The communication system of claim 1 including a region manager means for communicating between a network and a region with a plurality of network forward channel communications from the network to said broadcaster means and with a plurality of corresponding network reverse channel communications to the network from said aggregator means.

3. The communication system of claim 1 wherein a particular user is one of said users and travels from a first one of said broadcaster zones to a second one of said broadcaster zones and wherein said region manager means includes control means for assigning a first broadcaster forward channel and a first user reverse channel for said particular one of said users for said first zone and for assigning a second broadcaster forward channel and a second user reverse channel for said particular one of said users for said second zone.

4. The communication system of claim 1 wherein, for one of said zone manager means, collector means are co-located with said broadcaster means for said one of said zone manager means and wherein other collectors means are located at macro-diverse locations from said one of said zone manager means.

5. The communication system of claim 4 wherein said other collectors means are co-located with broadcaster means of other of said zone manager means.

6. The communication system of claim 1 wherein ones of said collector means use directional antenna means.
