Abstract
Abstract A method of dynamically allocating bandwidth of channels to cells in a communications cellular network according to user demand. Disjoint groups of cells are formed so as to minimize interference within each group, and a particular channel is assigned to each of the groups. The bandwidth of each channel then dynamically allocated by time division to each of the cells in a group according to user demand in each of the cells.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
89 words
A method of allocating communications bandwidth to cells in a cellular network, comprising: a. forming disjoint groups (super-cells) of said cells to minimize interference within each of said groups; b. assigning a particular channel of said common bandwidth to each of said groups; and c. allocating bandwidth of each of said channels to cells in each group to which each channel is assigned, said bandwidth of each of said channels being dynamically allocated according to user demand in each cell of a group having said each channel assigned thereto.
Claim 2
Dependent Claim
57 words
A method as recited in claim 1, wherein each of said groups are formed by the step of: assigning a channel to each cell of said network with a channel that is least assigned to all neighbors of said each cell, with each of said groups then being the set of cells having the same assigned channel.
Claim 3
Dependent Claim
42 words
A method as recited in claim 1 or 2, wherein said bandwidth of each of said channels is allocated to cells in a corresponding group by allocating a portion of time in super frame to each cell according to user demand therein.
Claim 4
Independent Claim
95 words
An apparatus for allocating communications bandwidth to cells in a cellular network, comprising: a. means for forming disjoint groups (super-cells) of said cells to minimize interference within each of said groups; b. means for assigning a particular channel of said common bandwidth to each of said groups; and c. means for allocating bandwidth of each of said channels to cells in each group to which each channel is assigned, said bandwidth of each of said channels being dynamically assigned according to user demand in each cell of a group having said each channel assigned thereto.
