摘要:
Provided is a light emitting device package, which includes a ceramic body, an ultraviolet light emitting diode, a support member, and a glass film. The ceramic body defines a cavity. The ultraviolet light emitting diode is disposed within the cavity. The support member is disposed on the body, and surrounds the cavity. The glass film is coupled to the support member, and covers the cavity. Since the light emitting device package includes the ceramic body to efficiently dissipate heat, and the glass film is directly attached to the ceramic body to decrease the number of components, thereby simplifying the manufacturing process thereof, and reducing the manufacturing costs thereof.
摘要:
A mobile station in a control hold mode wakes up at a time slot on a wake-up channel received from a base station, assigned thereto, and detects at least one predetermined indicator bit. If the detected indicator bit indicates that the base station has data to transmit, the mobile station starts monitoring a forward packet data control channel from the base station, in order to determine whether to make a transition to an active mode. Otherwise, if the detected indicator bit indicates that the base station has no data to transmit, the mobile station maintains the control hold mode, thus preventing unnecessary power consumption.

摘要:
A reverse data transmission apparatus and method in a mobile communication system. A mobile station receives information about an MADR (Maximum Allowable Data Rate) from a base station in a first predetermined frame period, determines a data rate equal to or lower than the MADR, and requests the determined data rate to the base station. If an MADR received from the base station in a second frame period following the first frame period is higher than the requested data rate, the mobile station starts data transmission. Then, the mobile station measures a traffic to pilot ratio (T/P) from the base station and controls the data rate according to the T/P during data transmission.
