<p>A radio communication system comprises a communication channel for the transmission of data from a secondary station to a primary station. The secondary station is operable in a first (normal) and a second (gated) mode, with a reduced quantity of data being transmitted in the second mode. The secondary station generates a coded word providing information on the transport formats applicable to the channel and transmits this coded word repeatedly to the primary station. Different coding schemes are used to generate the coded word in each mode of operation, thereby enabling improved performance in gated mode compared to truncating the coded word. In one embodiment data transmissions take place in frames, each comprising a plurality of timeslots and the coded word is transmitted once per frame. During gated mode transmissions do not take place in every timeslot, and the coded word is punctured compared to that transmitted in normal mode.</p> |
