Evolved multimedia broadcast multicast service on enhanced component carriers

An apparatus for communication at a wireless device, comprising:

• means for determining that a set of resources is scheduled for an evolved multimedia broadcast multicast service (eMBMS);
• means for determining that a first symbol period of the set of resources is associated with a cell-specific reference signals (CRS) preamble and a second symbol period of the set of resources is a unicast control symbol period;
• means for identifying a control message in the unicast control symbol period indicating a unicast data transmission utilizing the set of resources;
• means for performing a CRS on/off detection for a subframe associated with the set of resources;
• means for receiving at least one CRS during the subframe based at least in part on the CRS on/off detection;
• and
• means for combining the at least one CRS with accumulated CRS data based at least in part on the CRS on/off detection.

An apparatus for communication at a wireless device, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory;
• wherein the instructions are executable by the processor to cause the apparatus to:
• determine that a set of resources is scheduled for an evolved multimedia broadcast multicast service (eMBMS);
• determine that a first symbol period of the set of resources is associated with a cell-specific reference signals (CRS) preamble and a second symbol period of the set of resources is a unicast control symbol period;
• identify a control message in the unicast control symbol period indicating a unicast data transmission utilizing the set of resources;
• perform a CRS on/off detection for a subframe associated with the set of resources;
• receive at least one CRS during the subframe based at least in part on the CRS on/off detection;
• and
• combine the at least one CRS with accumulated CRS data based at least in part on the CRS on/off detection.

• determine that a first symbol period of the set of resources is associated with a cell-specific reference signals (CRS) preamble and a second symbol period of the set of resources is a unicast control symbol period;
• identify a control message in the unicast control symbol period indicating a unicast data transmission utilizing the set of resources;
• perform a CRS on/off detection for a subframe associated with the set of resources;
• receive at least one CRS during the subframe based at least in part on the CRS on/off detection;
• and
• combine the at least one CRS with accumulated CRS data based at least in part on the CRS on/off detection.
