Claim 0:
1. An apparatus of a base station operable for standalone operation to communicate over an anchor channel in an unlicensed spectrum, bandwidth reduced low complexity and coverage enhancement (BL/CE) cell, the apparatus comprising:
one or more processors configured to:
identify, at the base station associated with the BL/CE cell, a system information block (SIB) for bandwidth reduced operation in the unlicensed spectrum;
encode, at the base station, a master information block (MIB) for bandwidth reduced operation in the unlicensed spectrum for transmission over a broadcast channel to a user equipment (UE), wherein the MIB includes a system frame number (SFN) that is indicated using seven bits, a subframe offset within one discovery reference signal (DRS) period, and SIB scheduling information that includes a transport block size (TBS) for the SIB; and
encode, at the base station, the SIB for transmission in a downlink over an anchor channel on two DRS subframes to the UE, wherein the SIB is to configure a hopping sequence for the UE, and wherein the anchor channel corresponds to a frequency known to the UE to reduce a cell search period for initial access when the UE is configured for frequency hopping; and

a memory interface configured to retrieve the SIB from a memory.
