Title:
METHOD AND NB-IOT DEVICE FOR RECEIVING NRS
Document Type and Number:
WIPO Patent Application WO/2019/013512
Kind Code:
A1
Abstract:
One disclosure of the present specification proposes a method for receiving a narrowband reference signal (NRS) by a narrow band Internet-of-things (NB-IoT) device. The method may comprise a step for receiving an NRS in at least one orthogonal frequency division multiplexing (OFDM) symbol. The at least one OFDM symbol may exist in a time division duplex (TDD) subframe. When the TDD subframe corresponds to a TDD special subframe, the at least one OFDM symbol for receiving the NRS may be determined according to which special subframe configuration index is used by the TDD special subframe among multiple TDD special subframe configuration indices.
