AI Technical Summary

Problems solved by technology

Additionally, non-independent control of the carriers makes it difficult to adjust power across multiple carriers and control interference between devices and / or channels
Furthermore, in addition to non-independent control, multicarrier control systems do not yet have the ability to properly scale the power allocation between carriers when given conditions
This lack of control independence and scaling makes it extremely difficult to deliver the desired quality of service

Embodiment Construction

[0021] 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 two or more carriers to determine a power level of the set of high speed packet access signals. The method also includes adjusting at least one of open loop control, inner loop control, or outer loop control in view of the power level of the set of packet access signals.

[0022] Note that in one or more 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 both computer stora...

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 / 160,902, entitled "POWER CONTROL IN MULTI-CARRIER HSUPA," filed March 17, 2009, which The entirety of the case is incorporated herein by reference. technical field [0003] The following description relates generally to wireless communication systems and, more particularly, to providing loop power control for multiple carriers associated with 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 these multiple access systems include Code Division Multiple Access (CDMA) systems, Time Division Multiple Acce...
