METHOD AND BASE STATION FOR UPLINK TIMESLOT ASSIGNMENT IN UTRA TDD SYSTEM

摘要

A method for uplink timeslot assignment in UTRA TDD system is disclosed. The method includes the following steps: The cell that prepares to assign one cross-timeslot to uplink determines the interference to the cell that caused by the downlink transmission of one neighboring cell which has assigned one cross-timeslot to downlink, wherein the power of the downlink transmission signal is limited according to BS load control of said neighboring cell which has assigned cross-timeslot to downlink. Determining the accumulated sum of the interference to the cell that caused by the downlink transmission signal and system noise of the cell. Determining the propagation loss threshold value for the cell that has assigned cross-timeslot to uplink, wherein the threshold value is in inverse proportion to the accumulated sum. Base station compares the propagation loss that measured by user equipment with the threshold value. And only when the propagation loss that measured by user equipment is lower than the threshold value, the user equipment is allowed to assign the cross-timeslot to uplink. A base station system that uses said method is also provided.
