## Abstract

A base station apparatus capable of communicating with user equipment terminals using an uplink shared channel includes a radio resource allocation unit configured to allocate radio resources to the shared channel after allocating radio resources to a random access channel, a control channel, and a Message-3 in a random access procedure.

## Claims

### Claim 1

A base station apparatus capable of communicating with user equipment terminals using an uplink shared channel, comprising:
a radio resource allocation unit configured to allocate radio resources to the shared channel according to dynamic scheduling after allocating radio resources to a random access channel and a control channel, allocating radio resources according to persistent scheduling, and allocating radio resources to a Message-3 in a random access procedure, wherein the Message-3 in the random access procedure is transmitted with a radio resource allocated by the base station apparatus,
wherein the radio resource allocating unit releases the radio resources allocated according to the persistent scheduling, when the radio resources have been allocated according to the persistent scheduling to a user equipment terminal to which the radio resources are to be allocated according to the dynamic scheduling.
