Abstract:
1. A method for determining soft handover diversity set thresholds, comprising: a terminal determining a dynamical addition threshold of a diversity set corresponding to the terminal according to a first predetermined information, wherein the first predetermined information comprises Carrier-to-Interference-and-Noise Ratios (CINRs) of all base stations in the diversity set and parameters carried in a downlink channel descriptor message received by the terminal from base stations; and the terminal respectively determining a dynamical deletion threshold of each base station in the diversity set according to a second predetermined information, wherein in respect of each base station, the second predetermined information comprises CINRs of base stations in the diversity set with CINRs more than the CINR of the base station and parameters carried in the downlink channel descriptor message, wherein the terminal determines the dynamical addition threshold H_Add_d of the diversity set according to the first predetermined information via the following formula: wherein Slope is a preset weighted parameter more than zero, Add_Intercept is a preset static addition threshold determined according to the parameters carried in the downlink channel descriptor message, and is a sum of the CINRs of all base stations in the diversity set, and wherein the terminal respectively determines the dynamical deletion threshold H_Delete_d of each base station in the diversity set according to the second predetermined information via the following formula: wherein Slope is a preset weighted parameter more than zero, Delete_Intercept is a preset static deletion threshold determined according to parameters carried in the downlink channel descriptor message, and is a sum of the CINRs of base stations in the diversity set with CINRs more than the CINR of the base station.
