Embodiment Construction

[0039] This embodiment relates to a method for determining a transmission rate and a base station device and a terminal device using the same. When the transmission rate is set separately on the uplink and downlink according to the environment of the transmission line between the base station device and the terminal device , among the uplink or the downlink, information concerning which one of the uplinks or downlinks should be used as a priority line is obtained, and the transmission rate is set based on the information.

[0040] The terminal device according to this embodiment determines which link should be prioritized among the uplink or downlink based on the application startup operation from the operator, and transmits the information to the base station device 200 . Furthermore, the base station apparatus according to this embodiment detects a request signal to set either the uplink or the downlink as the priority line based on a signal received from a terminal apparatus...

Abstract

To prevent transmission efficiency from being degraded due to a change of modulation schemes. A terminal apparatus (100) decides, in response to an operator's activation of an application, which line is to be given a priority, an upstream line or a downstream line, and requests a base station apparatus (200). The base station apparatus (200) detects, from signals received from the terminal apparatus with which it must communicate at a variable transmission rate, a request signal related to the upstream or downstream line having been given the priority. When the request signal indicates that the downstream line has been given the priority, the base station apparatus (200) stops an execution of transmission rate change of the upstream line that is accompanied by a halt of communication of the downstream line. Conversely, when the request signal indicates that the upstream line has been given the priority, the base station apparatus stops an execution of transmission rate change of the downstream line that is accompanied by a halt of communication of the upstream line.

Description

technical field [0001] The invention relates to a transmission speed determination technology. In particular, it relates to a transmission rate determination method for changing the transmission rate in communication, and a base station device and a terminal device using the method. Background technique [0002] In a wireless communication system, although the transmission line environment fluctuates with time, there is an adaptive modulation method as one of techniques for increasing the transmission speed in such a transmission line environment. The adaptive modulation method controls the modulation method according to the transmission line environment. For example, when the transmission line environment is judged to be poor, a high-reliability modulation method is used to transmit data. On the other hand, when the transmission line environment is judged to be good, a multi-information modulation to transmit data. When a base station device and a terminal device included...
