Abstract:
A system comprising:a base station; and a plurality of terminals, wherein said base station generates a busy tone signal to control a probability of said plurality of terminals transmitting reservation packets, said probability including a value larger than 0 and less than 1, and wherein each of said plurality of terminals makes references to said busy tone signal to control transmission of a reservation packet, and wherein said busy tone signal is represented by P(t) which satisfies the following equation: R(t)â€²=R(tâˆ’1)/P(tâˆ’1), P(t)=(Tâˆ’I(t))/R(t)â€²where R(t) denotes a number of reservation packets transmitted by said plurality of terminals in time slot t, R(t)â€² denotes a number of transmission request reservation packets in time slot t, I(t) denotes a number of data packets generated in time slot (t), T denotes a number of simultaneously allowable packets, and P(t) denotes a transmission probability of reservation packets in a time slot t.
