METHODS AND APPARATUS FOR ERROR CORRECTION FOR COORDINATED WIRELESS BASE STATIONS
First Claim
1. A method of operating a first wireless transmitter, the method comprising:
- receiving one or more data packets from a second wireless transmitter;
receiving one or more transmission parameters from the second wireless transmitter; and
transmitting a partial backward error correction data packet for the one or more data packets, the partial backward error correction data packet being based at least in part on the one or more transmission parameters received from the second wireless transmitter;
wherein the one or more data packets has not been previously encoded and transmitted from the first wireless transmitter.

Abstract
Methods and apparatus for coordinated error correction among a set of wireless base stations in communication with one another. In one embodiment, the wireless base stations are part of a cellular network having various cellular base stations (including a serving base station, and multiple supplemental base stations), and transmit multiple redundant versions of a transport block using a Hybrid Automatic Repeat Request (HARQ) based scheme. The aggregate of the multiple redundant versions of the transport block are soft combined and acknowledged (ACK) or not-acknowledged (NACK) by the cellular equipment. The serving base station and supplemental base station devices dynamically configure the bundled acknowledgment operation based on various desired operational attributes relating to the operational parameters of the network.

10. A method of optimizing inter-cell operation within a multi-cell wireless network, comprising:
-
transmitting a first one or more data packets from a first cell; and selectively scheduling at least one other cell for the transmission of subsequent error correction data packets, the subsequent error correction data packets comprising redundant information useful for the correction of the first one or more data packets; wherein the transmitting and selectively scheduling cooperate to substantially reduce a transmission power required for the first cell of the network. - View Dependent Claims (11, 12, 13)

14. Receiver apparatus, comprising:
-
a digital processor; a wireless interface in data communication with the digital processor; and a storage apparatus having a storage medium with at least one computer program stored thereon, the at least one computer program comprising a plurality of computer executable instructions that when executed by the digital processor; receive a transmission schedule from a first transmitter over the wireless interface; receive a first data packet from a first transmitter over the wireless interface; receive a second error correction data packet from at least one second transmitter over the wireless interface; decode the received first data packet in conjunction with the second error correction data packet; and transmit an acknowledgement message. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. Base station apparatus, comprising:
-
a digital processor; a wireless interface in data communication with the processor; a network interface in data communication with the processor, the network interface coupled to at least one other base station apparatus; and a storage apparatus having a storage medium with at least one computer program stored thereon, the at least one computer program comprising a plurality of computer executable instructions that when executed by the digital processor; generates a first data packet from a transport block; transmits the transport block via the network interface to the at least one other base station apparatus, responsive to receiving the transport block, the at least one other base station apparatus generates a second data packet from the transport block; and transmits the first data packet via the wireless interface, wherein the first data packet substantially differs from the second data packet. - View Dependent Claims (22, 23, 24, 25, 26)
