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 receiving the NRS on at least one or more orthogonal frequency division multiplexing (OFDM) symbols. The one or more OFDM symbols are in a time division duplex (TDD) subframe. If the TDD subframe corresponds to a TDD special subframe, the one or more OFDM symbols for receiving the NRS is determined based on which TDD special subframe configuration index among a plurality of TDD special configuration indexes is used by the TDD special subframe.
Claims19
A method of receiving a narrowband reference signal (NRS), the method performed by a narrowband internet of things (NB-IoT) device and comprising:
- determining information regarding a time division duplex (TDD) special subframe configuration, among a plurality of TDD special subframe configurations that each configures a plurality of downlink (DL) orthogonal frequency division multiplexing (OFDM) symbols and at least one uplink (UL) OFDM symbol within a TDD special subframe;
- and
- receiving the NRS on at least one DL OFDM symbol among the plurality of DL OFDM symbols within the TDD special subframe, wherein a symbol location of the at least one DL OFDM symbol for receiving the NRS is determined based on the TDD special subframe configuration.
A narrowband internet of things (NB-IoT) device configured to receive a narrowband reference signal (NRS), the NB-IoT device comprising:
- a transceiver;
- at least one processor;
- and
- at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
- determining information regarding a time division duplex (TDD) special subframe configuration, among a plurality of TDD special subframe configurations that each configures a plurality of downlink (DL) orthogonal frequency division multiplexing (OFDM) symbols and at least one uplink (UL) OFDM symbol within a TDD special subframe;
- and
- receiving, via the transceiver, the NRS on at least one DL OFDM symbol among the plurality of DL OFDM symbols within the TDD special subframe,
- wherein a symbol location of the at least one OFDM symbol for receiving the NRS is determined based on the TDD special subframe configuration.
