Reselection in a wireless communication system
First Claim
Patent Images
1. A method in a wireless communication device, the method comprising:
- receiving, at the device, a downlink transmission including a reference signal from a base station while camped on the base station in idle mode;
estimating, at the device, a quality metric of a hypothetical paging channel reception based on the reference signal, wherein the quality metric is an indicator of an error rate of paging channel reception;
determining whether to perform reselection evaluation of a neighboring base station by the device based on the estimated quality metric.

Abstract
A wireless communication device includes a transceiver coupled to a controller configured to cause the device to receive a downlink transmission including a reference signal from a base station while camped on the base station in idle mode, to estimate a quality metric of a hypothetical paging channel reception based on the reference signal, and to determine perform reselection evaluation of a neighboring base stations based on the estimated quality metric.

18. A method in a wireless communication device, the method comprising:
-
receiving, at the device, a downlink transmission including a system information broadcast (SIB) message; estimating, at the device while camped on a base station in idle mode, a quality metric of a hypothetical paging channel reception based on the SIB message; determining whether to perform reselection evaluation of a neighboring base station by the device based on the estimated quality metric. - View Dependent Claims (19, 20, 24)
