User terminal and radio communication method
In order to perform appropriate communication in an unlicensed band, a user terminal according to one aspect of the present disclosure includes a receiving section that receives at least one of a synchronization signal block and a reference signal for measurement in a given duration of a frequency domain to which listening is applied, and a control section that controls reception of a physical downlink channel based on a transmission candidate position of at least one of the synchronization signal block and the reference signal for measurement when the physical downlink channel is received in the given duration.
1. A terminal comprising:
a receiver that receives a configuration for a synchronization signal/physical broadcast channel (SS/PBCH) block transmission candidate position in a transmission duration in which one or more SS/PBCH blocks are transmitted in an unlicensed spectrum, wherein the SS/PBCH block transmission candidate position corresponds to an SS/PBCH block index; and
a processor that controls, based on the configuration, reception of a physical downlink shared channel, assuming that the physical downlink shared channel is not mapped to a resource corresponding to the SS/PBCH block transmission candidate position regardless of whether or not the one or more SS/PBCH blocks are transmitted in the resource,
wherein a number of SS/PBCH blocks with a given SS/PBCH block index transmitted in the transmission duration is not larger than one.
2. The terminal according to claim 1 , wherein the receiver receives, by using higher layer signaling, a configuration for the transmission duration.
3. The terminal according to claim 1 , wherein a plurality of SS/PBCH block transmission candidate positions corresponding to the given SS/PBCH block index is configured in the transmission duration.
4. The terminal according to claim 1 , wherein the resource is a physical resource block including the SS/PBCH block transmission candidate position.
5. A radio communication method for a terminal, comprising:
receiving a configuration for a synchronization signal/physical broadcast channel (SS/PBCH) block transmission candidate position in a transmission duration in which one or more SS/PBCH blocks are transmitted in an unlicensed spectrum, wherein the SS/PBCH block transmission candidate position corresponds to an SS/PBCH block index; and
controlling, based on the configuration, reception of a physical downlink shared channel, assuming that the physical downlink shared channel is not mapped to a resource corresponding to the SS/PBCH block transmission candidate position regardless of whether or not the one or more SS/PBCH blocks are transmitted in the resource,
wherein a number of SS/PBCH blocks with a given SS/PBCH block index transmitted in the transmission duration is not larger than one.
6. A base station comprising:
a transmitter that transmits a configuration for a synchronization signal/physical broadcast channel (SS/PBCH) block transmission candidate position in a transmission duration in which one or more SS/PBCH blocks are transmitted in an unlicensed spectrum, wherein the SS/PBCH block transmission candidate position corresponds to an SS/PBCH block index; and
a processor that controls, by using the configuration, so that a physical downlink shared channel is not mapped to a resource corresponding to the SS/PBCH block transmission candidate position regardless of whether or not the one or more SS/PBCH blocks are transmitted in the resource,
wherein a number of SS/PBCH blocks with a given SS/PBCH block index transmitted in the transmission duration is not larger than one.
7. A system comprising a base station and a terminal, wherein the base station comprises:
a transmitter that transmits a configuration for a synchronization signal/physical broadcast channel (SS/PBCH) block transmission candidate position in a transmission duration in which one or more SS/PBCH blocks are transmitted in an unlicensed spectrum, wherein the SS/PBCH block transmission candidate position corresponds to an SS/PBCH block index; and
a processor that controls, by using the configuration, so that a physical downlink shared channel is not mapped to a resource corresponding to the SS/PBCH block transmission candidate position regardless of whether or not the one or more SS/PBCH blocks are transmitted in the resource, and
the terminal comprises:
a receiver that receives the configuration; and
a processor that controls, based on the configuration, reception of the physical downlink shared channel, assuming that the physical downlink shared channel is not mapped to the resource regardless of whether or not the one or more SS/PBCH blocks are transmitted in the resource,
wherein a number of SS/PBCH blocks with a given SS/PBCH block index transmitted in the transmission duration is not larger than one.
