Radio resource assignment method for physical channel in uplink, and transmitter for mobile apparatuses

摘要

A radio resource assignment method for a physical channel in an uplink directed from a mobile apparatus to a base station in a radio communication system, includes: assigning a contention-based channel and a scheduled channel according to one of a time division scheme, a frequency division scheme, and a hybrid scheme of the time division scheme and the frequency division scheme. In addition, radio resources are properly assigned to each of the contention-based channel, a common control channel of the scheduled channel, and a shared data channel of the scheduled channel.

主权项

1. A mobile station comprising:
a scheduling control unit configured to assign a shared control channel to a channel band where a plurality of frequency blocks, each of which includes a plurality of subcarriers, are arranged in a frequency direction, and to assign a shared data channel to at least one of the frequency blocks of the channel band; and a transmitting unit configured to transmit signals on the shared control channel and the shared data channel which are assigned in the scheduling control unit, wherein the scheduling control unit performs assignment for the shared control channel so as to form a comb-shaped spectrum, and performs assignment for the shared data channel so as to form a continuous spectrum, and wherein the scheduling control unit assigns the shared control channel over the whole channel band where the plurality of frequency blocks, each of which includes the plurality of subcarriers, are arranged in the frequency direction.
