1. A method of wireless communications by a base station, comprising:mapping at least one of a physical broadcast channel (PBCH) or a beamformed reference signal (BRS) to tones of a symbol of a subframe, wherein the mapping is independent of system bandwidth, and wherein the mapping comprises:
mapping coded bits of one period of PBCH transmission to a plurality of segments; and
for each segment, mapping coded bits of that segment to a fixed starting offset regardless of available resource for the transmission; and
transmitting the at least one of the PBCH or BRS in the symbol according to the mapping.
