Power control and carrier allocation are the main focus of work on interference management in 3G heterogeneous networks. This work introduces interference management in 3G small base stations by coordinating the allocation of orthogonal variable spreading factor codes (OVSF) in order to improve both the guaranteed data rate and the system sum rate. The(More)
IEEE 802.11ah is a WiFi standard developed to support M2M communications, among other things. It caters for sub 1 GHz long range transmissions. However, this long range exacerbates the hidden node problem. Sectorization and grouping have been proposed to mitigate the hidden node problem. Sectorization can also be used to eliminate the overlapping basic(More)
In this paper, we present a power allocation technique that improves the sum rate and energy efficiency without reducing the minimum data rate of an established resource block allocation technique. To achieve this, the technique is implemented in two stages where the first is for ensuring that the minimum data rate remains unchanged. The second stage is for(More)
