Abstract:
1. A method of automatic retransmission of messages in a point-to-multipoint wireless communication network where a base station controller (BSC) communicates with a plurality of customer premises equipments (CPE), using frames having an upstream portion and a downstream portion, the method comprising the steps of: selecting physical and media access control (MAC) parameters for automatic retransmission of messages, the physical and MAC parameters for the downstream portion being selected independently for each customer premises equipment of the plurality of customer premises equipment and the physical and MAC parameters for the upstream portion being selected independently for said each customer premises equipment; transmitting the physical and MAC parameters from the BSC to the CPEs; wherein the physical and MAC parameters are selected based on previous communication between the base station controller and said each customer premises equipment; and allocating a first part of the upstream portion of a frame as a shared resource for enabling CPEs of a first group to contend for transmitting messages associated with automatic retransmission and a second part of the upstream portion of the frame as an unshared resource for enabling CPEs of a second group to transmit individual messages associated with automatic retransmission.
