Abstract:
1. An information processing apparatus communicating with a communication apparatus comprising: a channel quality indicator acquisition unit configured to acquire a channel quality indicator indicating a quality of a first channel derived by the communication apparatus at a first interval; a transmission power control information acquisition unit configured to acquire power control information controlling a transmission power of the information processing apparatus for a second channel at a second interval shorter than the first interval; and an interval information transmission unit configured to transmit interval information changing a value of the first interval, wherein the interval information transmission unit permits transmitting of said interval information when said communication apparatus is in soft-hand-off condition, wherein the value of the first interval is changed based on an average value of a signal-to-interference ratio error and a number of users of the information processing apparatus, wherein the average value of the signal-to-interference ratio and the number of users are categorized into a respective one of three predetermined categories: a low category, a mid category, and a high category, and wherein, for shortening the first interval, both of the average value of the signal-to-interference ratio and the number of users need to be categorized to the low category.
