Abstract
A terminal apparatus performs a random access procedure; and receives a physical channel, in which the random access procedure includes a 2 step contention based random access procedure, a 4 step contention based random access procedure, and a non-contention based random access procedure, and the physical channel indicates an initiation of any of the 4 step contention based random access procedure and the non-contention based random access procedure.
Claims6
A terminal apparatus comprising:
- a higher layer processing unit configured to perform a random access procedure;
- and
- a receiver configured to receive a physical channel,
- wherein the random access procedure includes a 2 step contention based random access procedure, a 4 step contention based random access procedure, and a non-contention based random access procedure,
- the physical channel indicates an initiation of any of the 4 step contention based random access procedure and the non-contention based random access procedure, and
- the higher layer processing unit initiates, based on the physical channel, any of the 4 step contention based random access procedure and the non-contention based random access procedure.
A communication method used for a terminal apparatus, the communication method comprising the steps of:
- performing a random access procedure;
- and
- receiving a physical channel,
- wherein the random access procedure includes a 2 step contention based random access procedure, a 4 step contention based random access procedure, and a non-contention based random access procedure,
- the physical channel indicates an initiation of any of the 4 step contention based random access procedure and the non-contention based random access procedure, and
- based on the physical channel, any of the 4 step contention based random access procedure and the non-contention based random access procedure is started.
