Early termination of a base station identity code procedure in TD-SDCMA

摘要

An early BSIC (base station identity code) abort procedure includes comparing a first signal strength of a serving cell with a first threshold and comparing a second signal strength of a target cell to a second threshold. The first threshold is a sum of a network indicated threshold and a user equipment (UE) threshold. The second threshold is a difference between the network indicated threshold and the UE threshold. When the first signal strength is below the first threshold and the second signal strength is above the second threshold, the base station identity code (BSIC) procedure is initiated. A number of BSIC failure attempts is adaptively set before terminating the BSIC procedure.

1. A method, by a user equipment (UE), of wireless communication for inter radio access technology (IRAT) measurement, comprising:
comparing a first signal strength of a time division synchronous code division multiple access (TD-SCDMA) serving cell with a first threshold, in which the first threshold is a sum of a network indicated threshold and a user equipment (UE) threshold; comparing a second signal strength of a target global system for mobile communications (GSM) cell to a second threshold, in which the second threshold is a difference between the network indicated threshold and the UE threshold; initiating a base station identity code (BSIC) procedure when the first signal strength is below the first threshold and the second signal strength is above the second threshold; and adaptively setting a number of BSIC failure attempts before terminating the BSIC procedure.
