Abstract

A terminal according to an aspect of the present disclosure includes a control section that assumes a certain restriction being applied to a communication supporting a subcarrier spacing wider than a certain subcarrier spacing, and a transmitting/receiving section that performs transmission/reception processing of the communication based on the certain restriction. According to an aspect of the present disclosure, it is possible to suitably suppress adverse influence of a time taken for communication switching even when a relatively wide subcarrier spacing is used.

Claims (21)

1. A terminal comprising:

a processor that determines that there is a gap of a certain length between two signals corresponding to a subcarrier spacing of 480 kHz or 960 kHz in a frequency band higher than 52.6 GHz; and

a receiver that performs reception processing of the two signals based on the gap,

wherein the receiver performs reception processing of a signal after a bandwidth part (BWP) switching, based on a BWP switching delay time and in response to a request of the BWP switching, corresponding to the subcarrier spacing of 480 kHz or 960 kHz in the frequency band higher than 52.6 GHz.

2. The terminal according to claim 1 , wherein the two signals are synchronization signal blocks.

3. The terminal according to claim 1 , wherein the receiver performs reception processing of a signal after beam switching, based on a beam switching delay time corresponding to a subcarrier spacing of 480 kHz in a frequency band higher than 52.6 GHz.

4. A radio communication method for a terminal comprising:

determining that there is a gap of a certain length between two signals corresponding to a subcarrier spacing of 480 kHz or 960 kHz in a frequency band higher than 52.6 GHz;

performing reception processing of the two signals based on the gap; and

performing reception processing of a signal after a bandwidth part (BWP) switching, based on a BWP switching delay time and in response to a request of the BWP switching, corresponding to the subcarrier spacing of 480 kHz or 960 kHz in the frequency band higher than 52.6 GHZ.

5. A base station comprising:

a processor that determines that there is a gap of a certain length between two signals corresponding to a subcarrier spacing of 480 kHz or 960 kHz in a frequency band higher than 52.6 GHZ;

a transmitter that performs transmission processing of the two signals based on the gap,

wherein the transmitter performs transmission processing of a signal after a bandwidth part (BWP) switching, based on a BWP switching delay time and in response to a request of the BWP switching, corresponding to the subcarrier spacing of 480 kHz or 960 kHz in the frequency band higher than 52.6 GHz.

6. A system comprising a terminal and a base station, wherein:

the terminal comprises:

a processor that determines that there is a gap of a certain length between two signals corresponding to a subcarrier spacing of 480 kHz or 960 kHz in a frequency band higher than 52.6 GHz; and

a receiver that performs reception processing of the two signals based on the gap,

wherein the receiver performs reception processing of a signal after a bandwidth part BWP) switching, based on a BWP switching delay time and in response to a request of the BWP switching, corresponding to the subcarrier spacing of 480 kHz or 960 kHz in the frequency band higher than 52.6 GHZ, and

the base station comprises:

a transmitter that performs transmission processing of the two signals based on the gap.
