A DC block with a band-notch characteristic using a defected ground structure (DGS), includes a pair of coupled lines for being formed parallel to each other on one surface of a dielectric and blocking a flow of a DC, and at least one DGS for being formed on an area of the rear surface of the dielectric corresponding to each coupled line and comprising an etched region formed by etching a part of a ground surface bonded to the dielectric and a metal region formed in the etched region. Accordingly, the stop band of the desired bandwidth in the desired communications band can be formed and the size of the communications system can be reduced.

A mobile terminal for communicating with a network entity includes a RF module for communicating with the network entity, a display for displaying information to a user, a memory for storing data relating to operation of the mobile terminal, and a processor. The processor may be configured to adjust power control step size of the mobile terminal by receiving signal condition data from the network entity, and adjusting the power control step size based on the signal condition data. The mobile terminal may also be configured to operate with 1xEV-DO systems.
摘要:
A reference signal including a quality indication is injected into the reverse link signal received at a base station. The transmit power of the reference signal is controlled by the base station through reverse link power control, and the base station estimates the reverse link load from the transmit power of the reference signal. As the load increases, the transmit power must increase to overcome interference. The reference signal may be generated by a signal generator within the base station; by a mobile station hardwired to the base station; or by a mobile station proximate the base station, sending the reference signal over the air interface. The reverse link load may be estimated directly from reference signal transmit power, or from the reference signal transmit power minus a minimum reference signal transmit power in the absence of interference.
摘要:
A method and apparatus to reduce the overhead of frequently sent signaling messages is provided. Various methods are presented which facilitate conveying information that is unchanged from information in the earlier part of the message, or in a previous signaling message, without sending the previous information in its entirety.
