CELL DISCOVERY

摘要

This disclosure generally relates to cell discovery. In one embodiment, an association between a cell and an indicator index corresponding to one of a set of scrambling sequence indicators may be predefined. A first base station may transmit the set of scrambling sequence indicators to a second base station. The second base station may select an indicator from the indicators according to the predefined association, for generating a reference signal to be transmitted to user equipment. The user equipment may determine identification information of the cell based on the received reference signal and the predefined association, and transmit the identification information to the first base station. In this way, the user equipment may determine the identification information of the cell based on the received reference signal, and then transmit the identification information to the base station, such that the load on the base station may be reduced in the procedure of cell discovery.

主权项

1. A method implemented at least in part by a base station, comprising:
transmitting a set of scrambling sequence indicators to a further base station, such that the further base station selects an indicator from the indicators for generating a reference signal, the indicator selected according to a first association between a cell of the further base station and an indicator index corresponding to the indicator; and receiving identification information of the cell from user equipment, the identification information obtained by the user equipment based on the reference signal and the first association.
