Abstract
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.
Claims6
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.
