Patent claim: A method of wireless communication performed by a user equipment UE comprising suspending communication in a first radio access technology RAT to access a second RAT and determining based on information obtained from before suspending the communication whether to determine at least one of Doppler estimation channel estimation automatic gain control frequency tracking loop DC estimation SNR estimation or time tracking loop based on the information obtained before the suspension of the first RAT or to determine the at least one of Doppler estimation channel estimation automatic gain control frequency tracking loop DC estimation SNR estimation or time tracking loop based on information obtained after resuming the communication in the first RAT.

Related passage: FIG.16 at a and b is an explanatory view of the autonomous gap generation control executed by the mobile station device.The mobile station device receives a pilot signal of a common pilot channel from the base station device measures an instantaneous CQI at a given CQImeasurement interval and reports the measured instantaneous CQI to the base station device.The instantaneous CQI is instantaneous power of the pilot signal as an example.At the same time the mobile station device calculates an average CQI by averaging the instantaneous CQIs at a given period.The mobile station device compares the measured average CQI with a CQI threshold of the system parameters.If the average CQI is greater than the CQI threshold the mobile station device sets a normal mode thereto see FIG 16 at a.If the average CQI is smaller than the CQI threshold the mobile station device sets a measurement mode for monitoring a base station device on a different frequency to the mobile station device see FIG.16 at a.If the measured instantaneous CQI is smaller than the average CQI in the measurement mode the mobile station device suspends reception or transmission at the frequency utilized by the connected base station device and generates a gap section.When receiving the report of the instantaneous CQI the base station device calculates the average CQI of the mobile station device similar to the mobile station device.The calculated average CQI is compared with the CQI threshold of the system parameters.If the average CQI is greater than the CQI threshold the base station device sets the normal mode thereto.If the average CQI is smaller than the CQI threshold the base station device sets the measurement mode thereto.If the measured instantaneous CQI is smaller than the average CQI in the measurement mode the base station device suspends the transmission of packet data addressed to the connectedmobile station device and generates a gap.FIG.16 at b is a partially enlarged view of FIG.16 at a and schematically shows a state where multiple gaps are generated continuously.Nonpatent Document 1 WCDMA Mobile Communication System by Keiji Tachikawa ISBN 4621048945 Nonpatent Document 2 3GPP TR Technical Report 25.858 and 3GPP HSDPAspecificationrelated document httpwww.3gpp.orgftpSpecshtmlinfo25series.htm Nonpatent Document 3 3GPP TR Technical Report 25.903 V0.2.0 200511 Continuous Connectivity for Packet Data Users.httpwww.3gpp.orgftpSpecshtmlinfo25903.htm Nonpatent Document 4 3GPP TR Technical Report 25.814 V1.1.1 20062 Physical Layer Aspects for Evolved UTRA.httpwww.3gpp.orgftpSpecshtmlinfo25814.htm Nonpatent Document 5 NTT DoCoMo Inc.Measurement for LTE Intraand InterRAT Mobility 3GPP TSG RAN WG2 Meeting50 Sophia Antipolis France 913 January 2006 R2060086.httpwww.3gpp.orgftptsgranWG2RL2TSGR250Documents
