User terminal and radio communication method
Measurement is efficiently performed while suppressing an increase in an overhead. A user terminal according to the present invention includes: a reception section that receives frequency information indicating a plurality of frequencies in a single component carrier; and a control section that, when a signal block including a synchronization signal and a broadcast signal is transmitted at each of the plurality of frequencies, controls measurement at the plurality of frequencies.
1. A terminal comprising:
a receiver that detects a synchronization (SS)/physical broadcast channel (PBCH) block of a plurality of SS/PBCH blocks which are transmitted respectively in different frequency locations within a carrier and receives a system information corresponding to the detected SS/PBCH block; and
a processor that uses a random access channel resource for a random access, the random access channel resource being determined based on the system information,
wherein even in a case that the plurality of SS/PBCH blocks have the same SS/PBCH block index, the processor does not assume that the plurality of SS/PBCH blocks are quasi co-located with respect to average gain, delay parameter, Doppler parameter, and spatial parameter.
2. The terminal according to claim 1 , wherein the system information indicates association between one or more indexes of one or more SS/PBCH blocks and one or more random access channel resources.
3. The terminal according to claim 1 , wherein the plurality of SS/PBCH blocks correspond to a plurality of cells, respectively.
4. A radio communication method for a terminal comprising:
detecting a synchronization (SS)/physical broadcast channel (PBCH) block of a plurality of SS/PBCH blocks which are transmitted respectively in different frequency locations within a carrier;
receiving a system information corresponding to the detected SS/PBCH block; and
using a random access channel resource for a random access, the random access channel resource being determined based on the system information,
wherein even in a case that the plurality of SS/PBCH blocks have the same SS/PBCH block index, the terminal does not assume that the plurality of SS/PBCH blocks are quasi co-located with respect to average gain, delay parameter, Doppler parameter, and spatial parameter.
5. A base station comprising:
a transmitter that respectively transmits a plurality of synchronization (SS)/physical broadcast channel (PBCH) blocks respectively in different frequency locations within a carrier and transmits a system information corresponding to a SS/PBCH block of the plurality of the SS/PBCH blocks; and
a processor that controls a random access using a random access channel resource determined based on the system information,
wherein even in a case that the plurality of SS/PBCH blocks have the same SS/PBCH block index, the processor does not assume that the plurality of SS/PBCH blocks are quasi co-located with respect to average gain, delay parameter, Doppler parameter, and spatial parameter.
6. A system comprising:
a terminal that comprises:
a receiver that detects a synchronization (SS)/physical broadcast channel (PBCH) block of a plurality of SS/PBCH blocks which are transmitted respectively in different frequency locations within a carrier and receives a system information corresponding to the detected SS/PBCH block; and
a processor that uses a random access channel resource for a random access, the random access channel resource being determined based on the system information; and
a base station that transmits the plurality of SS/PBCH blocks and transmits the system information,
wherein even in a case that the plurality of SS/PBCH blocks have the same SS/PBCH block index, the processor does not assume that the plurality of SS/PBCH blocks are quasi co-located with respect to average gain, delay parameter, Doppler parameter, and spatial parameter.
