Abstract: A display apparatus includes a plurality of light sources that are arranged in several rows at different intervals so that light emitted from the plurality of light sources may reach all regions of a display panel uniformly. Accordingly, a uniform dispersion of the light incident on the display panel may be achieved. Furthermore, distribution of light generated from the plurality of light sources on the display panel may be facilitated through a reflecting unit without the use of a light-guide plate or the like.

Abstract: A reverse link controlling method in a mobile communication system. To increase or decrease a reverse data rate, an MS receives threshold power information indicating a power threshold for a pilot channel from the BS and measures the reception power of the pilot channel received from the BS. When the MS is supposed to increase or decrease the current data rate, it increases the current data rate by two levels or decreases the current data rate by one level if the pilot reception power is higher than the power threshold, and increases the current data rate by one level or decreases the current data rate by two levels if the pilot reception power is equal to lower than the power threshold.

Abstract: A method of controlling reverse data transmission in a mobile communication system is disclosed. At a reverse data channel setup, an MS and a BS negotiate a reverse data rate and a transmission duration. After the reverse data channel is established, whether to permit reverse data transmission or not is determined periodically. Therefore, overhead in the MS and the BS is reduced and reverse transmission throughput is increased. The MS reports the amount of transmission data and its forward channel state to the BS periodically or non-periodically. Based on the information, the BS then controls reverse data rates individually. During data transmission, if the BS determines to change a data rate, it notifies a corresponding MS of the changed data rate. Thus, reverse data transmission is controlled adaptively according to a variable channel environment.

Abstract: A reverse link control method in a mobile communication system. To increase or decrease a reverse data rate, an MS receives access probabilities for at least one-level rate increases and decreases from each available data rate from a serving BS and stores them. Upon receipt of a reverse data rate increase or decrease command from the BS, the MS reads access probabilities for a current data rate and generates a random number. Then it compares the random number with the read access probabilities and, if the random number satisfies the read access probabilities, it increases or decreases its current data rate by one or more levels according to the read access probabilities.
