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.
