A cellular type mobile communication system comprising a plurality of cells, a plurality of base stations disposed in the respective cells, and a mobile station located in the cells. On reception of a control command for a transmission power from the mobile station, each base station increases or decreases the transmission power in response to the control command. In addition, each base station renews the transmission power so that the transmission power after increased or decreased approaches a predetermined reference power.

A cellular type mobile communication system comprising a plurality of cells, a plurality of base stations disposed in the respective cells, and a mobile station located in the cells. On reception of a control command for a transmission power from the mobile station, each base station increases or decreases the transmission power in response to the control command. In addition, each base station renews the transmission power so that the transmission power after increased or decreased approaches a predetermined reference power. gnor maps mobile stations having the first QoS level associated therewith to the first set and mobile stations having the second QoS level associated therewith to the second set.11. The scheduler of claim 10 wherein the mobiles stations of the first and at least second sets, respectively, are operable pursuant to a Bluetooth standard, and wherein the first QoS level associated with the first set is of a level greater than the second QoS level associated with the second set.12. The scheduler of claim 11 wherein assignations are made by said assignor are dynamically made, the assignations responsive, at least in part, to QoS level at which the selected communications are to be effectuated.13. The scheduler of claim 12 wherein the radio communication system communicates data packets, each data packet including a header portion and wherein indications of the QoS level are contained in the header portion of each of the data packets.14. The scheduler of claim 1 wherein the at least the first set of mobile stations defined by said assignor comprises the first set and at least a second set, a first hopping pattern further defined at the first set and a second hopping pattern further defined at the second set.15. The scheduler of claim 14 wherein the communications permitted between the fixed-site transceiver and the selected ones of the mobile stations comprise two-way communications upon a forward link and upon a reverse link and wherein, during a selected time period, communications effectuated between the mobile stations of the first set and the fixed-site transceiver are effectuated upon the forward link and communications effectuated between the mobile stations of the second set and the fixed-site transceiver are effectuated upon the reverse link.16. The scheduler of claim 1 wherein at least one of the at least the first set of mobile stations defined by said assignor comprises the fixed-site transceiver as a portion thereof.17. In a method for communicating in a radio communication system in which a plurality of mobile stations communicate by way of radio links with a fixed-site transceiver, an improvement of a method for allocating communication channels upon which to permit communications between the fixed-site transceiver and selected ones of the plurality of mobile stations, said method comprising: storing indications of identities of a plurality of mobile stations together with QoS level at which selected communications therewith are to be effectuated; defining at least a first set of mobile stations of the plurality of mobile stations, the first set having a maximum number, or fewer, of mobile stations; and assigning a communication channel upon which the selected communications between the mobile stations of the mobile stations of the at least the first set and fixed-site transceiver are to be effectuated. 18. The method of claim 17 wherein the fixed-site transceiver and the plurality of mobile stations comprise Bluetooth compatible devices and wherein the at least the first set of mobile stations defined during said operation of defining defines at least a first Bluetooth standard-defined piconet.19. The method of claim 18 wherein at least one of the at least first Bluetooth standard-defined piconet comprises the fixed-site transceiver as a portion thereof.20. The method of claim 18 wherein the maximum number of mobile stations forming the at least the first set of mobile stations defined during said operation of defining comprises seven mobile stations.21. The method of claim 18 wherein the mobile stations of the first set defined during said operation of defining have associated therewith a common QoS level at which the selected communications are to be effectuated.22. In a radio communication system in which a plurality of mobile stations communicate by way of radio links with a fixed site transceiver, an improvement of a scheduler for allocating communication channels upon which to permit communication betwe en the fixed-site transceiver and selected ones of the plurality of mobile stations, said scheduler comprising: a storage device coupled to the fixed-site transceiver, said storage device for storing indications of identities of the plurality of mobile stations together with quality levels at which selected communications therewith are to be effectuated; an assignor coupled to said storage device and capable of retrieving the indications stored thereat, said assignor selectably operable to define at least a first set and a second set of mobile stations of said plurality of mobile stations, a first hopping pattern further defined at the first set, and a second hopping pattern further defined at the second set, the first set having a maximum number, or fewer, of mobile stations, wherein each of the at least first set defined by said assignor further has a master device defined thereat, the master device having a value associated therewith, and the hopping pattern defined thereat determined by the value associated with the master device; and wherein the assignor is further for assigning a communication channel upon which communications between the mobile stations of the at least the first set and the fixed-site transceiver are to be effectuated. 23. The scheduler of claim 22 wherein a first master device defined at the first set further comprises a first clock and wherein the second master device defined at the second set further comprises a second clock, the first clock and the second clock maintained in time synchronization.24. The scheduler of claim 23 wherein the time synchronization between the first clock and the second clock includes a clock offset.25. The scheduler of claim 24 wherein the clock offset between the first clock and the second clock is formed of a summation of a first clock offset portion and a second clock offset portion.
