Abstract

A control method for a radio communication system, wherein a first apparatus transmits a radio signal used to select a radio resource to a second apparatus and when the second apparatus receives a radio signal for requesting allocation of a radio resource from the first apparatus, the second apparatus selects a radio resource to be allocated to the first apparatus based on a radio signal used to select the radio resource and transmits information of the selected radio resource to the first apparatus Consequently, the first apparatus transmits transmission data by using the radio resource specified by the information. The method includes regulating transmission of the radio signal used to select the radio resource to be allocated when the first apparatus receives a particular signal from the second apparatus.

Description

technical field [0001] Some aspects of the invention disclosed herein relate to wireless communication devices for wireless communication and control thereof. Background technique [0002] Various communication methods using wireless communication as communication means are known. [0003] Here, Long Term Evolution (LTE) is described as an example of a wireless communication system that performs wireless communication. [0004] figure 1 is a diagram describing a data transmission flow (uplink transmission) from a mobile station as an example of a wireless communication device to a base station as an example of a wireless communication device. [0005] In order to communicate with a base station, a mobile station first transmits a random access signal by using a radio resource shared with another mobile station for signal transmission. When receiving a random access signal, the base station transmits a response signal to the mobile station to establish uplink synchronizati...
