Abstract:
1. A method of operating a system in which multiple remote units share access to a common base station, the method being to allocate bandwidth in the system, the method comprising: periodically, or in response to receiving a packet from a first remote unit, the received packet including a poll-me indication to poll the first remote unit, allocating more bandwidth to the first remote unit and; sending a bandwidth indication to the first remote unit of an increase in-uplink bandwidth allotment to the first remote unit such that the bandwidth indication can be used by the first remote unit for either data transfer or to make a bandwidth request as determined by the first remote unit; and as a result of sending the bandwidth indication to the first remote unit, either wherein the bandwidth request message includes an incremental bandwidth request unless the first remote station has determined that an aggregate bandwidth request should be transmitted, in which case the bandwidth request message includes an aggregate bandwidth request based on a determined aggregate bandwidth requirement, such that it can be determined from a received aggregate bandwidth request if at least one incremental bandwidth request that was sent by the first remote unit was not received.
