Document Type and Number:
WIPO Patent Application WO/2012/173250
Kind Code:
A1
Abstract:
Provided are a wireless communication system, a base station, a mobile station, and a wireless communication method, by which control time before the transmission of uplink data becomes possible can be shortened, to provide faster user experiences when the amount of the uplink data is small. A base station (100) transmits collision-type access permission to a plurality of mobile stations, the collision-type access permission including information of a collision-type access channel which is a wireless resource other than the wireless resource allocated in response to a scheduling request, and which is a wireless resource that can be used by the plurality of mobile stations to transmit uplink data. A mobile station (200A) transmits uplink data to the base station using the collision-type access channel on the basis of the collision-type access permission received from the base station.
