Abstract:
1. A method of operating a first communications device to communicate with a second communications device in a system having a plurality of transmission intervals, each transmission interval communicating at least one symbol, a first pair of said transmission intervals being utilized by a first pair of communications devices, said first pair of communications devices including said first and second communications devices, the first and second communications devices having an existing connection, said first pair of transmission intervals including a first transmission interval in which the first communications device can transmit and a second transmission interval in which the first communications device or the second communications device can transmit, the first and second transmission intervals being non-overlapping in time, the first transmission interval preceding the second transmission interval, the method comprising: transmitting on the first transmission interval a first signal indicating a request to transmit to said second communications device; transmitting data in a data transmission interval to the second communications device, said data transmission interval occurring subsequent to said second transmission interval; and transmitting a second signal from the first communications device to the second communications device in the second transmission interval, prior to transmitting the data in the data transmission interval, wherein the second signal conveys additional information corresponding to said data.
