  • Apparatus and methods of receive diversity (RXD) full cell search
    Patent number: 9432918
    Abstract: Apparatus and methods of receive diversity (RxD) full cell search by a user equipment (UE) in a wireless communication system are described. In an aspect, a first set of received energies of a first signal received at a first antenna and a second set of received energies of a second signal received at a second antenna may be separately determined. Based thereon, a set of peak energies and corresponding antenna indices, along with a slot timing of at least one cell corresponding to the set of peak energies and corresponding antenna indices, may be determined. A frame timing and a scrambling code for the at least one cell then may be determined using a respective one of the first antenna and the second antenna corresponding to each of the set of peak energies and the corresponding antenna indices, along with the respective slot timing of the at least one cell.
