Method and system for rate prediction in coordinated multi-point transmission
Abstract:
A downlink cooperative multi-point (CoMP) framework of a wireless communication system reduces inter-node interference and increases channel gain by scheduling a user equipment (UE) based on improved interference estimates and gain estimates. The UE computes a gain scaling factor (μ) based on theoretical gain and actual gain for each available scheduling scenario and transmits the gain scaling factors to an anchor node of the UE's radio reporting set (RRS). The anchor node computes an internal scaling factor (ν) based on the received gain scaling factors (μ) to estimate an actual gain for the scheduling scenarios. The UE also periodically transmits quantized interference estimates to the anchor node. The anchor node predicts a rate for the scheduling scenarios and schedules the UE based on the internal scaling factor (ν), the gain scaling factors (μ), and the interference estimates.
