Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a relationship between a first set of antenna ports, used for demodulation reference signals (DMRS) associated with a machine-type communication physical downlink control channel (MPDCCH) and used for the MPDCCH, and a second set of antenna ports used for cell-specific reference signals (CRS); receive CRS on one or more antenna ports of the second set of antenna ports; and receive the MPDCCH using at least the CRS based at least in part on the relationship. Numerous other aspects are provided.

Abstract: Methods, systems, and apparatuses for wireless communication are disclosed. In one aspect, a user equipment (UE) determines to perform a synchronization procedure and receives at least one synchronization signal. The UE may generate a detection metric based at least in part on the at least one synchronization signal and compare the detection metric or detection metrics accumulated since determining to perform the synchronization procedure with a detection threshold. The detection threshold may be associated with the at least one synchronization signal utilized to determine whether the synchronization procedure can be terminated prior to receiving a predetermined number of synchronization signals. The UE may continue or terminate the synchronization procedure based at least in part on a result of the comparison.
