Abstract: A radio communication system comprising a primary station and a plurality of secondary stations has a communication channel for the transmission of information from a secondary station to the primary station. The secondary station can adjust its output transmission power at a plurality of different rates, and the primary station can instruct the secondary station which of the plurality of rates it should use. The primary station determines the optimum rate for the secondary station to use by measurement of characteristics of signals received from the secondary station, for example the average signal to interference ratio, and is instructs the secondary station accordingly. Other indications may be used to determine or verify the optimum rate, for example further properties of the received signals or information on the speed of the secondary station.

Abstract: A method of communicating data from a data source (10) on one bus system (1) to a data sink (30) on another bus system (3) whose cycle rate is similar to but not synchronised with that of the first bus system comprises the steps of determining the tolerances with respect to frequency between the first and second bus cycle periods, assembling the data for transmission into packets, allocating a variable size, dependent on the tolerances, data payload to the packets, and including within the packets a header indicating the size of the payload. The receiving bus (3) receives these packets and extracts the data payload from the packets using the packet header indication of the size of the data payload.

Abstract: A radio communication system has a random access channel for the transmission of data (214) from a secondary station to a primary station. Such a channel is intended for use by secondary stations having data (214) to transmit to a primary station while not actually engaged in a call. By enabling access requests (202) to be transmitted with a greater range of possible signatures, a much greater number of degrees of freedom is available to a secondary station requesting access to a random access channel. This enables significantly improved efficiency of resource allocation by increasing the amount of information transmitted to the primary station by the access request (202).

Abstract: A radio communication system comprising a primary station and a plurality of secondary stations has a communication channel for the transmission of information from a secondary station to the primary station. The secondary station adjusts its output power in response to power control commands received from the secondary station, and can adjust its output transmission power at a plurality of different rates. The primary station can instruct the secondary station which of the plurality of rates it should use. The primary station determines the optimum rate for the secondary station to use by analysing the sequence of power control commands that it sends to the secondary station, and instructs the secondary station accordingly.

Such a channel is intended for use by secondary stations having data (214) to transmit to a primary station while not actually engaged in a call. By enabling access requests (202) to be transmitted with a range of time offsets relative to the boundary (302) of their time slot, a much greater number of degrees of freedom is available to a secondary station requesting access to a random access channel. This enables significantly improved efficiency of resource allocation by increasing the amount of information transmitted to the primary station by the access request (202).
