SYSTEM AND METHOD FOR COVERAGE ENHANCEMENTS OF BROADCAST CHANNELS

摘要

Methods and apparatus are provided for a base station to transmit and for a UE to detect broadcast information when the UE operates in a Coverage Enhancement (CE) mode. The base station transmits repetitions of signaling conveying broadcast information in one or more subframes of each frame in a quadruple of frames. The transmission is intermittent in time. To detect the broadcast information, the UE blindly combines and decodes the repetitions of signaling assuming their existence. The base station informs the pattern for the intermittent transmissions of the signaling to UEs connected to the base station or to other base stations.

1. A method comprising:
transmitting, by a base station to a first User Equipment (UEs), a first broadcast channel in a first Sub-Frame (SF) of every frame in every quadruple of frames and in the center six Resource Blocks (RBs) of a bandwidth and a second broadcast channel in a one or more SFs of every frame in a first number of quadruples of frames and in the center six RBs of the bandwidth, wherein a frame includes ten SFs, the first number of quadruples of frames is from a second number of quadruples of frames with the first number being smaller than the second number, and wherein the first broadcast channel conveys a first encoded Master Information Block (MIB) for the quadruple of frames and the second broadcast channel conveys a second encoded MIB for the quadruple of frames.
