Title:
無線通信システムにおける上り通信方法及び無線端末
Document Type and Number:
Japanese Patent JP4905007
Kind Code:
B2
Abstract:
A radio terminal (2) estimates a reception quality of an uplink signal at a radio base station (1) based on a downlink signal received from the radio base station (1), and controls transmission timing to the radio base station (1) of a transmission request (SI) for obtaining permission to transmit the uplink signal. Whereby, it is possible to control the transmission timing of the request for obtain permission to transmit the uplink signal from the radio base station (1), decrease a transmission electric power of the radio terminal (2), and obtain an expected throughput.
