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.
