AI Technical Summary

Problems solved by technology

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

Embodiment Construction

[0020] 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 for a set of high speed packet access signals. The method also includes automatically scaling at least one of the independent power controls in view of the determined power level of the set of high speed packet access signals.

[0021] It should be noted 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 include...

Abstract

A method for wireless communications is provided. The method includes applying independent power controls 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 power levels for the set of high speed packet access signals. The method also includes automatically scaling at least one of the independent power controls in view of the determined power levels for the set of high speed packet access signals. The method also includes setting the minimum power offset of the data channel independently on each carrier.

Description

[0001] Claim of priority under 35 U.S.C. §119 [0002] This application claims priority to U.S. Provisional Patent Application No. 61 / 218,315, entitled "POWER CONTROL IN MULTI-CARRIER HSUPA," filed June 18, 2009, which states 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 power scaling 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 such as bandwidth and transmit power. Examples of these multiple access systems include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequ...
