Method of handling network entry in a cell cluster and related communication device
First Claim
Patent Images
1. A method of handling a network entry for a communication device in a wireless communication system, the method comprising the steps of:
- receiving a first system information transmitted by a cell in a cell cluster of the wireless communication system;
determining an anchor cell in the cell cluster according to the first system information; and
performing the network entry with the determined anchor cell by receiving control information transmitted by the determined anchor cell, to camp on the determined anchor cell, wherein the network entry comprises a random access procedure;
wherein the cell cluster operates at a carrier frequency;
wherein the first system information comprises a cell identity (ID), and the cell ID is for determining the anchor cell;
wherein at least one of a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a common reference signal (CRS), a second system information and a paging information is not transmitted by a non-anchor cell in the cell cluster, when the at least one of the PSS, the SSS, the CRS, the second system information and the paging information is transmitted by the determined anchor cell;
wherein a first power level for receiving at least one of the second system information and the paging information is different from a second power level for receiving at least one of the PSS, the SSS and the CRS.

Abstract
A method of handling handovers in a cell cluster comprises transmitting, by an anchor cell in the cell cluster, first control information with a first power level to a communication device of the wireless communication system, for the communication device to perform a network entry according to the first control information; and transmitting, by the anchor cell, second control information with a second power level lower than the first power level to the communication device, for the communication device to obtain channel information according to the second control information.
