Abstract
Provided are a configuration method and a transmission method of a new reference signal for frequency offset estimation in a novel wireless communication system. The method may include configuring a synchronization signal to be transmitted through a first bandwidth part of one or more bandwidth parts configured by dividing an entire bandwidth into one or more parts, allocating the one or more reference signals for estimating the frequency offset on one or more resources other than a resource for configuring the synchronization signal, and transmitting the one or more reference signals for estimating the frequency offset.
Claims15
A wireless device, comprising:
- a transmitter;
- a receiver;
- and
- a controller which controls the transmitter and the receiver to:
- receive, from a base station, a synchronization signal in a first set including one or more symbols;
- receive, from the base station, a radio resource control (RRC) signal including configuration information about a reference signal;
- and
- receive, from the base station, the reference signal in a second set including one or more symbols, based on the configuration information,
- wherein the reference signal is configured, based on a numerology.
A base station, comprising:
- a transmitter;
- a receiver;
- and
- a controller which controls the transmitter and receiver to:
- transmit, to a wireless device, a synchronization signal in a first set including one or more symbols;
- transmit, to the wireless device, a radio resource control (RRC) signal including configuration information about a reference signal;
- and
- transmit, to the wireless device, the reference signal in a second set including one or more symbols, based on the configuration information,
- wherein the reference signal is configured, based on a numerology.
An apparatus for a wireless device, comprising:
- a controller which controls a transmitter and a receiver of the wireless device to:
- receive, from a base station, a synchronization signal in a first set including one or more symbols;
- receive, from the base station, a radio resource control (RRC) signal including configuration information about a reference signal;
- and
- receive, from the base station, the reference signal in a second set including one or more symbols, based on the configuration information,
- wherein the reference signal is configured, based on a numerology.
