发明名称 Method and device for measuring a reference signal received quality in wireless communication system
摘要 A method for measuring by a terminal at least one or more transmission points among a first transmission point and a second transmission point, which are neighboring cells, in a wireless communication system. The method includes: measuring a reference signal strength indicator (RSSI) in a predetermined resource of a subframe; and measuring reference signal received quality (RSRQ) from the RSSI and reference signal received power (RSRP), where the predetermined resource is associated with the setting of an almost blank subframe (ABS) of the first transmission point for the subframe.

主权项 1. A method for measuring at least one of first and second transmission points (TPs) of a neighbor cell by a user equipment (UE) including a processor and a receiver, the UE belonging to a third TP of a serving cell in a wireless communication system, the method comprising: receiving, by the UE, an almost blank subframe (ABS) pattern of the first TP from the third TP; determining, by the UE, whether to use all orthogonal frequency division multiplexing (OFDM) symbols contained in a subframe or to use OFDM symbols, used for transmitting a reference signal (RS) of the first TP, among the OFDM symbols in the subframe for measuring Reference Signal Strength Indicator (RSSI) according to whether the subframe is corresponding to the ABS or a normal subframe based on the ABS pattern of the first TP; measuring, by the UE, the RSSI in the determined OFDM symbols of the subframe; measuring, by the UE, a Reference Signal Received Quality (RSRQ) based on the RSSI; transmitting a measurement report including the RSRQ to the third TP; and receiving at least one measurement subframe pattern and measurement resource information corresponding to the at least one measurement subframe pattern from a third TP of a cell including the user equipment (UE), wherein the subframe is contained in any one of the at least one measurement subframe pattern, and the OFDM symbols are indicated by measurement resource information corresponding to the measurement subframe pattern including the subframe, and wherein the at least one measurement subframe pattern and the measurement resource information corresponding to the at least one measurement subframe pattern are decided by the third TP that has received an ABS pattern of the first TP from the first TP, on the basis of the ABS pattern of the first TP.
