System and method for data transmission from multiple wireless base transceiver stations to a subscriber unit
First Claim
1. A cellular wireless communication system comprising:
- a scheduler unit, the scheduler unit receiving the protocol data units from a network and sub-dividing the protocol data units into sub-protocol data units, a plurality of base transceiver stations receiving the sub-protocol data units, and wirelessly transmitting the sub-protocol data units to a subscriber unit;
wherein the scheduler unit determines a schedule protocol for transmission of the sub-protocol data units by the plurality of base transceiver stations.

Abstract
The invention includes an apparatus and a method for scheduling wireless transmission of data blocks between multiple base transceiver stations and multiple receiver (subscriber) units. A scheduler unit receives the protocol data units from a network and sub-divides the protocol data units into sub-protocol data units. A plurality of base transceiver stations receive the sub-protocol data units, and wirelessly transmit the sub-protocol data units to a subscriber unit. The scheduler unit determines a schedule protocol for transmission of the sub-protocol data units by the plurality of base transceiver stations. The invention can include a base controller station that includes the scheduler unit. The invention can include a home base transceiver station that include the scheduler unit. A standard network interconnection can provide a transfer path of the sub-protocol data units between the base controller station and the base transceiver stations, or the home base transceiver station and the base transceiver stations. The sub-protocol data units can be encapsulated within standard data units that correspond with the standard network interconnection. The standard network connection can be an ATM network connection and the standard data units can be ATM cells. Alternatively, the standard network connection can be an IP network connection and the standard data units can be IP cells.
