摘要： A system for controlling a contention state for a communication link between a base station controller and customer premises equipment in point-to-multipoint communication. The contention state is controlled using a state machine, which includes a grant pending absent state in which a unicast request slot is maintained open for use by the customer premises equipment. During the grant pending absent state, the customer premises equipment sends no upstream data to the base station controller but can use the unicast request slot to request a data slot for sending upstream data to the base station controller. In the grant pending state, the customer premises equipment preferably uses piggybacking to request grant of a next data slot while sending upstream data to the base station controller.

摘要： A first traffic flow directed to a first wireless device is received. A second traffic flow directed to a second wireless device is received. These traffic flows comprise at least a first service flow classification and a second service flow classification. The first traffic flow and the second traffic flow are scheduled based on the first service flow classification and the second flow classification. This produces first and second device scheduled flows. The first and second device scheduled flows are classified into a plurality of flow classes. The plurality of flow classes comprises at least a first flow class and a second flow class. The first scheduled flow and the second scheduled flow are scheduled based on the first flow class and the second flow class. This produces an aggregate traffic flow.

摘要： Point to multipoint wireless communication, including 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. 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 conditions of a wireless communication link with each independent CPE. The BSC dynamically and adaptively allocates acknowledgement time slots within the upstream portion of the TDD frame, for use by each selected CPE. The BSC allocates some portion of the upstream bandwidth as a shared resource and some portion of the upstream bandwidth as unshared when there are messages received but not yet acknowledged. The BSC dynamically and adaptively response to acknowledgement and non-acknowledgement messages from each selected CPE, to integrate the automatic retransmission protocol with the TDD frame and the TDMA technique used within that frame.

摘要： A method of managing TDD across plural channels. In the method, frames are synchronized across the plural channels so that upstream frames and downstream frames coincide across the plural channels. Preferable, one channel is assigned to each of plural CPEs. Each CPE receives MAP messages on its assigned channel. A base station controller preferably generates the MAP messages. The MAP messages instruct the CPEs to switch channels so as to receive data bursts. The base station controller preferably includes a centralized scheduler that allocates channels and slots in those channels to the CPEs for receipt of the data bursts. Also, a method of receiving TDD messages. According to the method, CPEs switch channels based on received media access protocol messages so as to receive data bursts on plural channels. The channel to which a CPE switches need not be the same channel as the one on which the CPE receives its MAP messages. Additionally, systems, base stations, CPEs, and/or software that utilizes and/or implements these methods.

摘要： A method and system for adaptive point to multipoint wireless communication. The method and system integrate adaptive and dynamic responsiveness for communication parameters related to multiple characteristics of wireless communication links, both for a single sender and a single receiver, and for sets of multiple senders and multiple receivers. Moreover, the method and system are self-optimizing in the sense that they are adaptively and dynamically responsive to results of attempts to optimize parameters related to multiple characteristics of wireless communication links. Multiple characteristics of wireless communication links are optimized simultaneously, in that the optimal set of values for a plurality of N characteristics, rather fan N individual optimal values for each characteristic, is adaptively and dynamically selected.
