Abstract:
1. A radio communication system, comprising: a primary station operable to transmit a random access channel status message, the status message including an indicated highest available data rate on a plurality of available random access channels; and a plurality of secondary stations operable to receive the random access channel status message, wherein each secondary station is operable to determine which random access channel to request based on the random access channel status message; wherein the highest available data bit rate of the random access channel status message is indicated for each of the plurality of available random access channels in order to enable each secondary station to determine which random access channel to request; wherein the indicated highest available data rate of at least one available random access channel is lower than a highest data rate that is available to the at least one random access channel, based on a potential future demand for capacity; and wherein the primary station is operable to repeatedly transmit the random access channel status message so that intervals between repeated random access channel status messages are different.
