Algorithm for Physical Cell Identifier Allocation |
摘要 |
Methods, apparatus, and computer programs automatically allocating physical layer cell identifiers. A modulo 3 grouping and a modulo 30 grouping are provided for physical layer cell identifiers in a cellular communication system. The modulo 3 grouping is associated with first synchronization signal assignments and the modulo 30 grouping is associated with second synchronization signal assignments. A combination of first and second synchronization signals determines a physical layer cell identifier of a cell. A modulo 3 group is allocated to each of multiple cells of the system. After the allocation of the modulo 3 groups, a modulo 30 group is allocated to each of the multiple cells. The allocation of the modulo 30 groups incorporates the allocated modulo 3 group as a precondition for the modulo 30 grouping. To each cell, first and second synchronization signals are allocated on the basis of said allocation of the modulo 30 group. |

1. A method for automatically allocating physical layer cell identifiers in an apparatus, the method comprising:
providing a modulo 3 grouping and a modulo 30 grouping for physical layer cell identifiers in a cellular communication system, wherein the modulo 3 grouping is associated with first synchronization signal assignments and the modulo 30 grouping is associated with second synchronization signal assignments, and wherein a combination of a first synchronization signal and a second synchronization signal determines a physical layer cell identifier of a cell; allocating a modulo 3 group to each of a plurality of cells of the cellular communication system; allocating, after the allocation of the modulo 3 groups, a modulo 30 group to each of the plurality of cells of the cellular communication system, wherein the allocation of the modulo 30 groups incorporates the allocated modulo 3 group as a precondition to reduce a search space for the modulo 30 grouping; and allocating to each cell a first synchronization signal a second synchronization signal on the basis of said allocation of the modulo 30 group. |
