METHOD AND DEVICE FOR DETECTING INTER-FREQUENCY CELL SIGNALS IN A HETEROGENEOUS NETWORK

摘要

A method for reducing consumption of battery power of User Equipment (UE) during inter-frequency cell detection in a Heterogeneous Network (HetNet) is provided. The method includes receiving an indication from a serving cell operating on a first frequency layer about presence of a beacon signal transmission on the first frequency layer from a non-serving cell, an actual data transmission and reception of the non-serving cell occurs on a second frequency layer, determining whether the indication satisfies at least one triggering condition to initiate signal scanning on the first frequency layer for identifying the beacon signal transmission from the non-serving cell, scanning, when the received indication satisfies the triggering condition, the first frequency layer for identifying any beacon signal, decoding the beacon signal from the non-serving cell, and receiving assistance information from the serving cell to facilitate identification of the non-serving cell transmitting the beacon signals on the first frequency layer.

1. A method for reducing consumption of battery power of a User Equipment (UE) during an inter-frequency cell detection in a Heterogeneous Network (HetNet), the method comprising:
receiving an indication from a serving cell operating on a first frequency layer about a presence of a beacon signal transmission on the first frequency layer from a non-serving cell, an actual data transmission and reception of the non-serving cell occurring on a second frequency layer along with at least one trigger condition; determining whether the received indication satisfies at least one triggering condition to initiate signal scanning at the first frequency layer for identifying the beacon signal transmission from the non-serving cell; scanning, when the received indication satisfies the at least one triggering condition, the first frequency layer for identifying any beacon signal transmissions; decoding, when the received indication satisfies the at least one triggering condition, the beacon signal transmission from the non-serving cell; and receiving assistance information from the serving cell to facilitate identification of at least one non-serving cell transmitting the beacon signals on the first frequency layer.
