AI Technical Summary

Problems solved by technology

However, with regard to transmit power and multi-carrier control, previous systems were only able to achieve such control via power control that is universally applied to all carriers
This type of non-independent control of the carriers makes it difficult to regulate power between the carriers and to control interference between devices and / or channels
Furthermore, other than non-independent control, multicarrier control systems do not have the ability to properly scale the power allocation between carriers when given conditions
Said lack of control independence and scaling makes it extremely difficult to provide the desired quality of service

Embodiment Construction

[0019] Systems and methods are provided to control power across multiple carriers in a wireless network. In one aspect, a method for wireless communication is provided. The method includes applying independent power control to two or more carriers from a set of high speed packet access signals. The method includes monitoring power across the two or more carriers to determine a power level of the set of high speed packet access signals. The method also includes automatically adjusting at least one of the independent power controls in view of the determined power level of the set of high speed packet access signals.

[0020] Note that in one or more of the exemplary embodiments described herein, the functions described may be implemented in hardware, software, firmware, or any combination thereof. If implemented in software, the functions may be stored on or transmitted over as one or more instructions or code on a computer-readable medium. Computer-readable media includes bo...

Description

[0001] Claim of priority under 35 U.S.C. §119 [0002] This application claims the benefit of U.S. Provisional Patent Application No. 61 / 150,942, filed February 9, 2009, entitled "USER EQUIPMENT POWER CONTROL WITH MULTIPLE CARRIERS," and The entire content of said application is incorporated herein by reference. technical field [0003] The following description relates generally to wireless communication systems and, more particularly, to independent power control of multiple carriers for High Speed ​​Uplink Packet Access (HSUPA). Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, data, and so on. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth and transmit power). Examples of such multiple access systems include Code Division Multiple Access (CDMA) systems, Time Division ...
