Embodiment Construction

[0017] In this specification and claims, certain terms are used to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use The difference in name is used as a way to distinguish components, but the difference in function of components is used as a criterion for distinction. The "comprising / comprising" mentioned in the entire specification and claims is an open term, so it should be interpreted into "including / including but not limited to".

[0018] In order to make the above objects, features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail together with the accompanying drawings. The present invention will become apparent to those skilled in the art after reading the following detailed description of the embodiments illustrated in the accompanying drawings.

Abstract

The invention provides methods and apparatus for controlling transmitted power in a wireless system. The method includes generating information to be transmitted as a series of signal bursts, with a time interval between successive signal bursts, controlling individually a power level of each of said signal bursts with a power control signal to provide output signal bursts to be transmitted, and asserting a new power value of the power control signal during the time interval preceding each signal burst. The methods and apparatus provided by the invention make it be not burst by controlling the power control signal to limit generation of disordered frame signal and signal distortion by maintaining fixed power control signal.

Description

technical field [0001] The present invention relates to a wireless communication system, and more particularly to a method and an apparatus for separately controlling the transmission power level of each signal burst in a wireless system. The invention is particularly useful for Time Division Synchronous Code Division Multiple Access (TDSCDMA) wireless systems, but is not limited to Time Division Synchronous Code Division Multiple Access systems. Background technique [0002] Time Division Synchronous Code Division Multiple Access (TDSCDMA) is one of the third generation wireless communication standards. Different from Wideband Code Division Multiple Access (WCDMA) and Code Division Multiple Access 2000 (CDMA2000) that use frequency division multiplexing, TDSCDMA is designed to take advantage of Synchronous Code Division Multiple Access Address access technology to perform time division duplex (Time Division Duplex, TDD) / time division multiple access (Time Division Multip...
