Coordinated Evacuation Of Spectrum

摘要

A method for coordinating spectrum evacuation is described which is useful for spectrum sharing, authorized/licensed shared access, secondary access, dynamic spectrum access, cognitive radio, general authorized access, etc. whereby access to a spectrum can be increased via buying usage right from a higher priority, primary or incumbent user, and/or via opportunistic access to unoccupied/unused spectrum. Enabling efficient spectrum evacuation guarantees limited impact to system performance while ensuring that the other user gets the spectrum back when needed. The method includes selecting a first subset of UEs for transitioning from a first bandwidth to a second bandwidth. During a first time period, the method includes, for each UE in the first subset, instructing the UE to transition using dedicated signaling. Later, during a second time period, the method includes instructing a second subset of UEs to transition using broadcast signaling. Apparatus and computer readable media are also disclosed.

1. A method comprising:
selecting a first subset of user equipment from a plurality of user equipment for transitioning from a first bandwidth to a second bandwidth via dedicated signaling; during a first time period, for individual user equipment in the first subset of user equipment, instructing the individual user equipment to transition from the first bandwidth to the second bandwidth using dedicated signaling; and during a second time period, instructing a second subset of user equipment to transition from the first bandwidth to the second bandwidth using broadcast signaling, where the second subset of user equipment comprises at least one user equipment and where the first time period precedes the second time period.
