Patent ID: 10455506

Abstract:
Embodiments of the present disclosure provide an efficient discontinuous reception solution applicable in a Licensed-Assisted Access scenario. Particularly, there is provided a method for discontinuous reception at a tenninal device that is operable in both a licensed spectrum and an unlicensed spectrum. The method comprises receiving a subframe on an unlicensed carrier of the unlicensed spectrum during running of a first predetermined timer for which the terminal device is active and then determining whether the subframe is received from a base station that is operable in both the licensed spectrum and the unlicensed spectrum. Further, the method may also comprise extending the first predetermined timer in response to determining that the subframe is not received from the base station and during running of the extended first predetermined timer, keeping receiving a subframe on the unlicensed carrier of the unlicensed spectrum and determining whether the subframe is received from the base station. The extended first predetermined timer may be stopped in response that a subframe is received from the base station. Correspondingly, there is also provided an apparatus for discontinuous reception of a terminal device operable in both a licensed spectrum and an unlicensed spectrum.
