Abstract
Performing carrier aggregation for high-powered wireless devices that may cause interference to other wireless devices includes determining that a wireless device attached to an access node is assigned to a high power class and capable of operating in a carrier aggregation mode, initiating the carrier aggregation mode for the wireless device, and instructing the access node to utilize a frequency-division-duplexing (FDD) carrier deployed by the access node as a primary carrier for the wireless device. A handover of the wireless device to the FDD carrier may be triggered by a threshold level of interference caused by uplink transmissions from the wireless device when operating in the high-powered transmission mode on a TDD carrier.

A method for performing carrier aggregation, the method comprising:
- determining that a wireless device attached to an access node is:
- a high-power class wireless device based on a capability of the wireless device to transmit at a power level greater than a standard power level utilized by other wireless devices assigned to a standard power class, capable of operating in a carrier aggregation mode, and attached to a time-division-duplexing (TDD) carrier deployed by the access node;
- initiating the carrier aggregation mode for the high-power-class wireless device;
- and in response to determining that transmissions from the high-power-class wireless device are causing interference, instructing the access node to utilize a frequency-division-duplexing (FDD) carrier deployed by the access node as a primary carrier for the high-power-class wireless device in response to initiating the carrier aggregation mode and determining the high-power-class wireless device is attached to the TDD carrier, wherein the high-power-class wireless device uses the TDD carrier as a secondary carrier deployed by the access node in addition to the primary carrier.
A system for performing carrier aggregation in a wireless network, the system comprising an access node configured to deploy a frequency-division-duplexing (FDD) carrier and at least one time-division-duplexing (TDD) carrier;
- and a processing node communicably coupled to the access node, the processing node being configured to perform operations comprising:
- identifying a wireless device as a high-powered wireless device attached to the access node based on a capability of the wireless device to transmit at a power level greater than a standard power level utilized by other wireless devices assigned to a standard power class;
- determining that the high-powered wireless device is capable of operating in a carrier aggregation mode;
- determining that the high-powered wireless device is attached one of the TDD carriers deployed by the access node;
- and in response to determining that transmissions from the high-powered wireless device are causing interference, instructing the access node to communicate with the high-powered wireless device in the carrier aggregation mode utilizing the FDD carrier as a primary carrier and the TDD carrier as a secondary carrier based on identifying the high-powered wireless device, determining that the high-powered wireless device is capable of operating in carrier aggregation mode, and determining that the high-powered wireless device is attached to one of the TDD carriers deployed by the access node.
A processing node for performing carrier aggregation in a wireless network, the processing node being configured to perform operations comprising:
- determining that uplink transmissions from a high-powered wireless device attached to an access node are causing an interference to one or more standard-powered wireless devices, the high-power wireless device having a capability to transmit at a power level greater than a standard power level utilized by the one or more standard-powered wireless devices, wherein the high-powered wireless device and the one or more standard-powered wireless devices are attached to a time-division-duplexing (TDD) carrier deployed by the access node;
- triggering a handover of the high-powered wireless device to a frequency-division-duplexing (FDD) carrier deployed by the access node in response to determining that the uplink transmissions from the high-powered device are causing interference;
- and instructing the access node and the high-powered wireless device to utilize resources of the FDD and the TDD carriers deployed by the access node, wherein the FDD carrier functions as a primary carrier and at least one TDD carrier functions as a secondary carrier.
