PILOT DESIGN FOR UPLINK (UL) NARROW-BAND INTERNET OF THINGS (NB-IOT) - A simplified explanation of the abstract
This abstract first appeared for US patent application 18160486 titled 'PILOT DESIGN FOR UPLINK (UL) NARROW-BAND INTERNET OF THINGS (NB-IOT)
Simplified Explanation
The abstract describes a patent application related to methods and apparatus for pilot design for Narrow-Band Internet of Things (NB-IoT). The method involves determining binary code sequences to use as demodulation reference signals (DMRS) for a channel transmitted across subframes using tones within a resource block (RB) allocated to the UE for narrowband communication. The channel, along with the DMRS, is then transmitted using the determined binary code sequences, which can be based on binary random sequences like pseudo noise (PN) or Gold sequences.
- The patent application focuses on pilot design for NB-IoT.

Original Abstract Submitted
Certain aspects of the present disclosure relate to methods and apparatus for pilot design for Narrow-Band Internet of Things (NB-IoT). In certain aspects, the method generally includes determining at least one binary code sequence to use as a demodulation reference signal (DMRS) for a channel transmitted across one or more subframes using one or more tones within a resource block (RB) allocated to the UE for narrowband communication, and transmitting the channel including the DMRS using the one or more tones and the determined binary code sequence. In certain aspects, the binary code sequence may be determined based on a binary random sequence, such as pseudo noise (PN) or Gold sequence.
