Abstract
Methods and apparatus for providing quasi-licensed intra-cell spectrum reassignment. In one embodiment, the quasi-licensed spectrum utilizes 3.5 GHz CBRS (Citizens Broadband Radio Service) spectrum, and a “seamless” reassignment of wireless spectrum without disruption or loss of continuity to existing data sessions of the CBSD is provided via a pool of temporary RF carriers which act as substitutes for the currently allocated (granted) carriers. The served user devices (e.g., UEs) are instructed by the CBSD to migrate to a new “final” carrier via the substitutes, either directly or via one or more intermediary hops. In one variant, existing 3GPP signaling mechanisms between the UE and CBSD/eNodeB obviates any changes to extant UEs. Communications between the CBSD and its cognizant SAS/DP include new information objects which direct the CBSD to implement the handover functionality. In a further variant, inter-CBSD sector and frequency handovers are provided for using CBRS-plane and 3GPP signaling.
