A radio communication system comprises a secondary station having a communication channel with a primary station for the transmission of data packets from the primary station to the secondary station. In response to receipt of a data packet, the secondary station transmits a combined acknowledgement and quality parameter signal (402) to the primary station. The signal (402) indicates whether the data packet was received correctly and the value of the quality parameter enables the primary station to select transmission parameters for further data transmissions. A range of formats for the combined signal are possible. In one embodiment the quality parameter is a site selection signal indicating a preferred subset of primary stations for subsequent data transmissions. In another embodiment the quality parameter relates to the quality of the radio link and enables the primary station to select suitable modulation and coding schemes and/or transmit power levels.
A radio communication system having a communication channel between a secondary station and a primary station, the secondary station having receiving means for receiving data from the primary station, acknowledgement means for transmitting a signal to the primary station to indicate whether or not the data was received correctly and parameter signalling means for determining a quality parameter relating to packet transmission and for signalling details of the quality parameter to the primary station, wherein combined signalling is performed by the acknowledgement means and the parameter signalling means transmitting a single code word selected from a plurality of available code words and wherein the primary station has means for receiving the single code word and using the code word in determining whether or not the data was received correctly and the value of the quality parameter.
A secondary station for use in a radio communication system having a communication channel between the secondary station and a primary station, wherein receiving means are provided for receiving data from the primary station, acknowledgement means are provided for transmitting a signal to the primary station to indicate whether or not the data was received correctly and parameter signalling means are provided for determining a quality parameter relating to packet transmission and for signalling details of the quality parameter to the primary station, wherein combined signalling is performed by the acknowledgement means and the parameter signalling means transmitting a single code word selected from a plurality of available code words.
A method of operating a radio communication system having a communication channel between a secondary station and a primary station, the method comprising the secondary station receiving data from the primary station, transmitting an acknowledgement signal to the primary station to indicate whether or not the data was received correctly determing a quality parameter relating to packet transmission and signalling details of the quality parameter to the primary station, wherein combined acknowledgement and quality parameter signalling is performed by transmitting a single code word selected from a plurality of availabe code words and wherein the primary station receives the single code word and uses the code word in determining whether or not the data was received correctly and the value of the quality parameter.
A primary station for use in a radio communication system having a communication channel between a secondary station and the primary station, comprising:
