Abstract:
Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to techniques for single-frequency network (SFN) operation for machine-type communications (MTC) coverage enhancements. A method is provided for wireless communications by a user equipment (UE). The method generally includes detecting a synchronization signal transmitted from at least one of a plurality of transmission points, wherein each of the plurality of transmission points transmits a synchronization signal at a different offset time relative to a subframe boundary in a synchronized network, determining a subframe occurring a fixed time after detecting the synchronization signal to monitor for system information transmitted from at least one of the plurality of transmission points, and monitoring for a system information block during the determined subframe.
