RADIO COMMUNICATION SYSTEM |
摘要 |
<p>A radio communication system has a random access channel for the transmission of data (214) from a secondary station to a primary station. Such a channel is intended for use by secondary stations having data (214) to transmit to a primary station while not actually engaged in a call.A secondary station requesting access chooses a signature corresponding to the resource it requires to encode an access preamble (202). It may be known, from a resource availability message (402) broadcast by the primary station, that certain resources are unavailable. In this case the primary and secondary stations dynamically re-assign signatures corresponding to the unavailable resources to available resources, thereby reducing the probability of collisions between different secondary stations requesting the same resource.</p> |
