Abstract: A method includes selecting a received signal strength threshold level for determining whether an uplink resource of a terminal device is allocated from a first frequency band or from a second frequency band, and wherein the first frequency band is for terminal devices having a received signal strength above the received signal strength threshold level and the second frequency band is for terminal devices having the received signal strength below the received signal strength threshold level; outputting the received signal strength threshold level to be broadcasted in a cell; acquiring received signal strength values measured for a plurality of terminal devices in the cell and further acquiring and at least one performance metric target; and changing the received signal strength threshold level on the basis of the measured received signal strength values and the at least one performance metric target.

Abstract: 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.

Abstract: A method includes generating, by a network element, a radio map of a single-frequency network having multiple cells. The radio map represents power levels of radio signals at several locations in the network. A first function is selected to be applied, wherein the first function is based on the radio map and includes physical cell identity, PCI, modulo 3 values for the multiple cells as input. Different combinations of the PCI modulo 3 values are applied in the first function. Each candidate PCI modulo 3 value is selected from a group of three available options. An output of the first function is determined with respect to each combination. It is determined which combination provides the output fulfilling a predefined criterion. Those PCI modulo 3 values, which correspond to the output fulfilling the predefined criterion, are allocated to the multiple cells in order to reduce interference between primary synchronization sequences.
