1. A method of providing efficient access in a communication system between at least one transmitter disposed in a first ground area and a plurality of receiving stations having a plurality of different communication traffic requirements disposed in a second remote ground area, the method comprising the steps of:

  • (a) transmitting information destined for the plurality of receiving stations in a transmission burst; and

    (b) in performing step (a), transmitting in each transmission burst a plurality of q subbursts, each subburst comprising digital information associated with a particular receiving station and including preamble information bits and a plurality of information bits where the preamble bits comprise, inter alia, information for accessing the proper receiving station to receive and process the included information bits,characterized in thatthe method comprises the further steps of;

    (c) transmitting a plurality of s sequential transmission bursts during a predetermined time interval to form a communication sequence which communication sequence is sequentially repeated, each communication sequence being capable of providing q·

    s one-way transmission channels between the first and second ground areas; and

    (d) transmitting within n assigned subbursts in each transmission burst of the communication sequence the digital information associated with n·

    s transmission channels required between the at least one transmitter in the first ground area and a receiving station in the second ground area when n is an integer while transmitting within each of m assigned subbursts spaced at preselected intervals throughout the s transmission bursts of the communication sequence the digital information associated with m transmission channels required between said at least one transmitter in the first ground area and a receiving station in the second group area when m<

    s.
