Filed:

Nov 7, 2000

Appl. No.:

09/708170

Inventors:

David R. Dulin - San Francisco CA
Sanjay Kasturia - Palo Alto CA
Partho Mishra - Cupertino CA
Arogyaswami J. Paulraj - Stanford CA
Matthew S. Peters - Mountain View CA

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

H04Q 700

US Classification:

370329, 370338

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.

US Classification:

Abstract:

The invention includes an apparatus and a method for transmitting sub-protocol data units from a plurality of base transceiver stations to a subscriber unit. The method includes estimating time delays required for transferring the sub-protocol data units between a scheduler unit and each of the base transceiver stations. The method further includes the scheduler unit generating a schedule of time slots and frequency blocks in which the sub-protocol data units are to be transmitted from the base transceiver stations to the subscriber unit. The time delays are used to generate the schedule. The time delays can be used to generate a look ahead schedule that compensates for the timing delays of the sub-protocol data units from the scheduler unit to the base transceiver stations. The sub-protocol data units are wirelessly transmitted from the base transceiver stations to the subscriber unit according to the schedule. The time delays can be estimated by time-stamping sub-protocol data units before sub-protocol data units are transferred from the scheduler unit to the base transceiver stations, and estimating the time delays by comparing the times the sub-protocol data units are actually received by the base transceiver stations with the time-stamping.
