Abstract:
1. A method for allocating radio resources by a coordinating wireless communications device in a wireless communications network including a plurality of wireless communications devices, the wireless communications network occupying a plurality of narrow-band channels, the method comprising: obtaining supported narrow-band channels supported by a wireless communications device joining the wireless communications network, the supported narrow-band channels including a first subset of the narrow-band channels; partitioning the plurality of narrow-band channels into a set of non-overlapping operating channels, each of the non-overlapping operating channels including a second subset of the narrow-band channels, wherein the bandwidth of each of the non-overlapping operating channels is determined based on parameters selected from a group comprising the availability of the number of the narrow-band channels, the level of the interference of each narrow-band channel and the respective supported narrow-band channels supported by each of the wireless communications device; configuring the bandwidth of each of the non-overlapping operating channels, wherein a sum of the bandwidth of all non-overlapping channels is less or equal to a sum of the bandwidth of the plurality of narrow-band channels; assigning the wireless communications device to a non-overlapping operating channel; and allocating the radio resources to the wireless communications device, wherein the wireless communications device exchanges data with other wireless communications devices.
