Wireless system plan using in band-translators with diversity backhaul to enable efficient depolyment of high capacity base transceiver systems
First Claim
1. A method for assigning in-band radio frequency channels to a plurality of translating repeaters, home base stations and mobile stations in a cluster of cells forming a wireless cellular communication system, comprising the steps of:
- selecting three uplink sub-bands within an uplink band of frequencies for communications originating from said mobile stations;
selecting twenty-four alternately odd and even uplink channels for said translating repeaters within each said subband; and
selecting a set of mobile uplink channels for a set of mobile communication links between said mobile stations and said translating repeaters to include four of said uplink channels from each said subband.

Abstract
A wireless system architecture whereby high efficiency broadband transceiver systems can be deployed at an initial build out stage of the system in a cost-efficient manner. A home base station location is identified within each cluster of cells and rather than deploy a complete suite of base station equipment at each of the cells in the cluster, inexpensive translator units are located in the outlying cells serviced by the home base station in which low traffic density is expected. The translators are connected to directional antennas arranged to point back to the home base station site. The translators are deployed in such a way which meshes with the eventually intended frequency reuse for the entire cluster of cells. The translator to base station radio links operate in-band that is, within the frequencies assigned to the service provider. The available frequency bands are divided into at least two sub-bands, with frequency translations ocurring entirely within a given sub-band.

12. A wireless cellular communication system utilizing a plurality of channels, comprising:
-
a translating repeater for receiving and transmitting on three uplink sub-bands within an uplink band of frequencies assigned for communications originating from a plurality of mobile stations, said translating repeater configurable for operating on twenty-four alternately odd and even uplink channels within said subband; and a mobile uplink channel assigned to said translating repeater for providing a communication link between a mobile station and said translating repeater selected from the group consisting of a lowest frequency set of four even uplink channels in a lowest frequency one of said subbands, the second from lowest frequency set of four even uplink channels in a next higher frequency one of said subbands, and the third from lowest frequency set of four even uplink channels in a highest frequency one of said subbands. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A wireless cellular communication system utilizing a plurality of channels, comprising:
-
a translating repeater for receiving and transmitting on a plurality of uplink sub-bands within an uplink band of frequencies assigned for communications originating from a plurality of mobile stations, said translating repeater configurable for operating on a defined set of alternately odd and even uplink channels within said subband; and a mobile uplink channel assigned to said translating repeater for providing a communication link between a mobile station and said translating repeater selected from the group consisting of a lowest frequency set of even uplink channels in a lowest frequency one of said subbands, the second from lowest frequency set of even uplink channels in a next higher frequency one of said subbands, and the third from lowest frequency set of even uplink channels in a highest frequency one of said subbands.

21. A method for assigning in-band radio frequency channels to a plurality of translating repeaters, home base stations and mobile stations in a cluster of cells forming a wireless cellular communication system, comprising the steps of:
-
selecting a plurality of uplink sub-bands within an uplink band of frequencies for communications originating from said mobile stations; selecting a set of uplink channels for said translating repeaters within each said subband; selecting a set of mobile uplink channels for a set of mobile communication links between said mobile stations and said translating repeaters to include a plurality of said uplink channels from each said subband; selecting a set of backhaul uplink channels for a set of backhaul communication links between said translating repeaters and said home base stations to be each respectively spaced a pre-defined integer number of uplink channels from a corresponding mobile channel; defining a plurality of subsets of said uplink channels within each said subband, and assigning each said subset a predetermined integer number of uplink channels that are spaced a pre-defined integer number of uplink channels apart within said up-link sub-band; and wherein said up-link sub-bands, said plurality of subsets of said uplink channels, and said uplink and backhaul channels are all selected such that upon replacing one of said translating repeaters with a base station, said subset of uplink channels comprising said backhaul and mobile channels which had been assigned to said translating repeater can be assigned to said base station as uplink channels without causing interference with adjacent cells.
