METHODS AND APPARATUS FOR ESTIMATING WIRELESS BASE STATION COVERAGE AND MANAGING RESOURCES

Methods and apparatus for estimating a Citizens Broadband Radio Service Device's (CBSD's) coverage area using user equipment (UE) timing advance and/or power headroom information and allocating resources based on the estimate. In an exemplary method embodiment a Spectrum Access System: (i) receives, from a CBSD, user equipment (UE) information including at least one of timing advance or power headroom information for one or more UEs in communication with the CBSD; (ii) estimates, based on the received first UE information, a first CBSD coverage area; and (iii) makes a first resource allocation to the CBSD based on the estimated CBSD coverage area, the first resource allocation including an allocation of at least one of a frequency bandwidth allocation or transmission power allocation to the CBSD.
