Title: SYSTEM AND METHOD FOR RESOURCE MAPPING FOR COVERAGE ENHANCEMENTS OF BROADCAST CHANNELS
Abstract:
Methods and apparatus are provided for a base station to transmit repetitions of broadcast information and for a UE to detect the broadcast information. In a first method, the base station maps each repetition in a respective quadruple of subframe symbols while accounting for a possible different number of available sub-carriers among quadruplets of subframe symbols. In a second method, the base station maps the repetitions successively in available sub-carriers. For intermittent transmissions of repetitions, the UE can use the mapping structure of the repeated broadcast information to determine an existence of a transmission.
