Pattern indicator signal for new DMRS pattern

摘要

A small cell station communicates with user equipment utilizing a reduced overhead demodulation reference signal (DMRS) pattern when good channel conditions are detected. An indicator field is used to identify whether a reduced overhead DMRS pattern is being transmitted. If appropriate, the reduced overhead DMRS pattern is generated and transmitted by the small cell station and received and used by the user equipment as indicated by the indicator field.

主权项

1. A system comprising:
a transceiver having a power range corresponding to a small cell station; a processor; and a memory having instructions for execution by the processor to:
determine whether a reduced overhead demodulation reference signal (DMRS) pattern is appropriate for communications with multiple mobile devices communicatively coupled to the system operating as a small cell station;generate an indicator field to identify whether a reduced overhead DMRS pattern is being transmitted, wherein the indicator field comprises two bits to indicate (1) whether the DMRS pattern corresponds to a new carrier type (NCT) DMRS pattern, (2) a legacy DMRS pattern, and (3) whether the DMRS pattern is a reduced overhead DMRS pattern;generate the DMRS pattern consistent with the indicator field; andcause the indicator field and the DMRS pattern to be transmitted by the transceiver.
