Measurement in simultaneous TDD-LTE and TD-SCDMA/GSM systems

摘要

In a mobile device for wireless communication capable of communicating on multiple radio access technologies (RATs), cell selection may be improved by reusing cell measurements for inter-RAT cell selection. This will reduce the number of cell measurements taken and improve mobile device performance. A time threshold may be used to instigate new cell measurement to prevent cell measurement data from being outdated.

主权项

1. A method for wireless communication, comprising:
performing a signal measurement of a first radio access network at a first time following a paging occasion of the first radio access network; performing a signal measurement of a second radio access network at a second time following a paging occasion of the second radio access network, the paging occasion of the second radio access network occurring after the first time; determining when a time period between the first time following the paging occasion of the first radio access technology and the second time following the paging occasion of the second radio access technology is less than a determined threshold for determining whether to perform a new signal measurement of the first radio access technology; performing cell reselection using the signal measurement of the first radio access network and the signal measurement of the second radio access network in response to the time period being less than the determined threshold; performing a new signal measurement of the first radio access network when the time period between the first time and the second time is greater than the determined threshold; and performing cell reselection using the new signal measurement of the first radio access network in response to the time period being greater than the determined threshold.
