Abstract
Apparatuses, methods, and systems are disclosed for cell-specific reference signal generation. One apparatus includes a processor that determines a NB-IoT CRS frequency offset. The processor may determine a first CRS sequence based on the NB-IoT CRS frequency offset. The processor may also determine a first time-frequency resource set. The apparatus may also include a transmitter that transmits the first CRS sequence on the first time-frequency resource set.
Claims28
An apparatus comprising:
- a processor that:
- determines a frequency corresponding to a narrowband internet of things (“NB-IoT”) carrier;
- determines an NB-IoT cell-specific reference signal (“CRS”) frequency offset relative to the frequency;
- determines a first CRS sequence based on the NB-IoT CRS frequency offset and on a Physical Cell ID (“PCID”) derived from a NB-IoT synchronization signal, wherein the first CRS sequence is a subset of a second CRS sequence, and the second CRS sequence is a CRS sequence of a long term evolution (“LTE”) carrier;
- and
- determines a first time-frequency resource set;
- and
- a transmitter that transmits the first CRS sequence on the first time-frequency resource set.
