Abstract:
A method and an apparatus for automatic retransmission and error recovery for packet oriented point to multipoint communication, which integrates adaptive and dynamic responsiveness for parameters for automatic retransmission using wireless communication, are provided. A wireless communication link is divided into a downstream portion and an upstream portion. Parameters are selected for automatic retransmission independently for the downstream portion and the upstream portion of the wireless communication link. A BSC controls the selection of parameters for automatic retransmission for all CPE within a cell. As part of a TDD frame, in which the BSC and the CPE share communication bandwidth using a TDMA technique, the BSC includes its selection of parameters for automatic retransmission to be used by CPE within a control section of the TDD frame. The BSC dynamically and adaptively determines new selected parameters for automatic retransmission, in response to a wireless communication link with each independent CPE.
