Claim of US Patent No. 10,117,246

1. A method for wireless communication, comprising:determining, by a primary serving cell, that a neighbor cell operates in a shared access radio frequency spectrum;
determining one or more frequency ranges of the shared access radio frequency spectrum are not suitable for selection as a primary serving cell, the one or more frequency ranges including a frequency used by the neighbor cell; and
transmitting, by the primary serving cell, signaling information to a mobile device indicating that the neighbor cell is prohibited from serving as a primary serving cell based at least in part on the determination that the neighbor cell operates in the shared access radio frequency spectrum, wherein the primary serving cell is associated with a first base station and the neighbor cell is associated with a second base station, and wherein at least a portion of the signaling information comprises one or more frequency band identifiers or channel identifiers that identify the one or more frequency ranges of the shared access radio frequency spectrum.
