Abstract
Abstract A sectorized cell of a mobile radio network forms a first set which comprises a nucleus and a plurality of sectors disposed around the nucleus, the coverage of the cell being provided by transceiver units forming a second set, the first and second sets being associated on a one-to-one basis. Each sector comprising a core, at least one separation section being provided between the cores of two adjacent sectors, and the control station comprises an allocation unit capable of allocating the same resource to the cores of two adjacent sectors.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
101 words
Control station for a sectorized cell of a mobile radio network, said cell forming a first set which comprises a nucleus and a plurality of sectors disposed around said nucleus, the coverage of said cell being provided by transceiver units forming a second set, said first and second sets being associated on a one-to-one basis, each sector comprising a core, and at least one separation section being provided between said cores of two adjacent sectors, said control station comprising an allocation unit capable of allocating the same resource for use in said cores of said adjacent sectors at the same time.
Claim 2
Dependent Claim
101 words
Control station for a sectorized cell of a mobile radio network, said cell forming a first set which comprises a nucleus and a plurality of sectors disposed around said nucleus, the coverage of said cell being provided by transceiver units forming a second set, said first and second sets being associated on a one-to-one basis, each sector comprising a core, and at least one separation section being provided between said cores of two adjacent sectors, said control station comprising an allocation unit capable of allocating the same resource for use in said cores of said adjacent sectors at the same time.
Claim 3
Dependent Claim
38 words
Control station according to claim 1 wherein, said cell comprising two separate separation sections on either side of said core of a reference sector, said allocation unit is capable of allocating the same resource to said two sections.
Claim 4
Dependent Claim
28 words
Control station according to claim 1 wherein said allocation unit is adapted to allocate separate resources to a separation section and to said cores adjoining said separation section.
Claim 5
Dependent Claim
33 words
Control station according to claim 1 comprising a signalling unit for distributing the same signalling resources in a sector and in a portion of said nucleus defined by the extension of said sector.
Claim 6
Dependent Claim
51 words
Control station according to claim 4 comprising a location unit associated with said signalling unit for estimating the radial position of a terminal on the basis of a signalling resource used by said terminal in order to determine if it is in said sector or in said portion of said nucleus.
Claim 7
Dependent Claim
60 words
Control station according to claim 5 wherein said terminal being logged on in said sector, and said sector comprising a front border and/or a rear border, said location unit is also adapted to estimate the angular position of said terminal in order to determine if it is in said front border, said core or said rear border of said sector.
Claim 8
Dependent Claim
88 words
Control station according to claim 6, said transceiver unit of a sector comprising an array of conformable and steerable beam antennas, for generating a conformable, steerable beam, disposed at the center of said cell, comprising a control unit for controlling said transceiver unit so that: either said beam has a wide angle corresponding to that of said sector for conveying signalling resources enabling location of said terminal, or said beam has a narrow angle to direct traffic resources into one of said two borders or into said core.
Claim 9
Dependent Claim
30 words
Use of the control station according to claim 1 in a time division multiple access cellular digital mobile radio network in which separate signalling resources are allocated to each sector.
Claim 10
Dependent Claim
142 words
Method of allocating resources in a mobile radio cell, said cell comprising a nucleus surrounded by a plurality of sectors, said nucleus and all said sectors being each associated with its own transceiver unit, wherein, each sector comprising a core, and at least two separation sections being provided on either side of said core of a reference sector, a resource can be allocated to said nucleus if it is not being used in any of said sectors, a resource can be allocated to said core of said reference sector if it is already being used outside a first interference zone comprising said nucleus and said two separation sections adjacent said core, and a resource can be allocated to a separation section if it is already being used outside a second interference zone comprising said nucleus and two cores adjacent said separation section.
Claim 11
Dependent Claim
142 words
Method of allocating resources in a mobile radio cell, said cell comprising a nucleus surrounded by a plurality of sectors, said nucleus and all said sectors being each associated with its own transceiver unit, wherein, each sector comprising a core, and at least two separation sections being provided on either side of said core of a reference sector, a resource can be allocated to said nucleus if it is not being used in any of said sectors, a resource can be allocated to said core of said reference sector if it is already being used outside a first interference zone comprising said nucleus and said two separation sections adjacent said core, and a resource can be allocated to a separation section if it is already being used outside a second interference zone comprising said nucleus and two cores adjacent said separation section.
