Abstract: PROBLEM TO BE SOLVED: To minimize addition of an overhead and to minimize the need to change the structure of a physical layer by multiplexing plural packet data users to one downlink shared channel. SOLUTION: A multiplexer 26 is provided in an MAC sublayer 4a and inputs respective transport blocks from respective user data streams on signal lines 12a, 12b, and 12c. The multiplexer 26 multiplexes the transport blocks which are received from the all user data streams in a corresponding time frame into one signal on a signal line 28. Thus, a single piece of signal data, including the transport blocks for all the user in a certain time frame, is inputted to an encoding block 14d, a rate matching block 16d and an interleaving block 18d, and these process the multiplexed transport blocks.

Abstract: PROBLEM TO BE SOLVED: To provide a flexible and efficient asymmetrical multiplex access protocol by assigning a slot to incoming link communication or outgoing link communication so as to optimize a transmission efficiency of a channel. SOLUTION: End user devices (mobile stations) 1-6 use one optional communication protocol among plural communication protocols for traversing an aerial interface 12 via antennas 10, 11 and to hold communication with a closest bas station 13. The base station 13 uses is own broadcast control channel(BCCH) to broadcast information to all the mobile stations 1-6 within a range at all times. The base station 13 and the mobile stations 1-6 use a traffic channel(TCH) to hold communication and the base station 13 sends a feedback signal by the use of an ancillary control channel(ACCH) simultaneously. Data sent through a traffic channel(TCH) are divided into packets and are sent with proper control bits by the use of a proper slot.

Abstract: PROBLEM TO BE SOLVED: To obtain a method by which end user devices compete with each other in access to a common resource of a communication channel, by informing a controller of a communication system of a resource requested by an end user device to send another information packet in a sequence. SOLUTION: End user devices (mobile stations) 1-n use a random access channel(RACH) for sending a request to a system controller 21, so as to compete with each other in transmission permission of a data packet. A base station 20 uses a dynamic resource assignment table(DRA) 22 to decide whether or not a sufficiently idle resource is in existence in a network and returns permission of transmission of a data packet through the use of a feedback channel, when in existence. Thus, the method to request a resource in the communication system by the end user devices (mobile stations) 1-n is obtained.

Abstract: PROBLEM TO BE SOLVED: To allow the power control device for mobile to act at the time of inter-station start in the mobile radio communication system to reduce a time required to set an efficient power level. SOLUTION: The power control device controls a signal strength in the mobile radio communication system where communication is made by using a different channel at least first. The signal to interference ratio SIR of a signal received by a reception station is measured and the measured information is sent back to a transmission station 13 to provide an index of a proper power level to send succeeding signals.

Abstract: The invention relates to power control mechanisms for controlling signal strength in a mobile wireless communication systems which communicate, at le ast initially, over different channels. By measuring the Signal-to-Interference ratio in signals received by a receiving station and returning that information to th e transmitting station, an indication of appropriate power levels at which to transmit subs equent signals is given.

Abstract: The invention relates to communication systems in which end-user devices contend for access to shared resources of a channel in the communica tionsystem. End-user devices sending data in packets ove r the communication channel piggyback requests for changes in allocated resources for transmission of an other packet. A system controller changes the resource allocated to individual end -user devices depending upon the piggyback requests, in order to optimise the thro ughput of the channel. A packet switched network may thus act like a circuit switch ed network if required.
