摘要

A base station can operate a first serving cell on a licensed carrier frequency and a second serving cell on an unlicensed carrier frequency. The base station can perform a listen before talk (LBT) on the unlicensed carrier frequency for a first time duration. The base station can determine that the unlicensed carrier frequency is free. The base station can transmit an activation command on the first serving cell for receipt by a UE, the activation command being configured to activate the UE to receive transmissions from the base station on the second serving cell. The base station can transmit after determining that the unlicensed carrier frequency is free, a reserve transmission on the unlicensed carrier frequency at least until the base station begins transmission of the activation command on the first serving cell.

說明書

FIG. 2 illustrates a possible configuration of a computing system to act as the base station 104. The base station 104 may include a processor/controller 210, a memory 220, a database interface 230, a transceiver 240, input/output (I/O) device interface 250, and a network interface 260, connected through bus 270. The base station 104 may implement any operating system, such as Microsoft Windows?, UNIX, or LINUX, for example. Client and server software may be written in any programming language, such as C, C++, Java or Visual Basic, for example. The server software may run on an application framework, such as, for example, a Java? server or .NET? framework.

The controller/processor 210 may be any programmable processor. Various embodiments of the disclosure may also be implemented or partially implemented on a general-purpose or a special purpose computer, a programmed microprocessor or microcontroller, peripheral integrated circuit elements, an application-specific integrated circuit or other integrated circuits, hardware/electronic logic circuits, such as a discrete element circuit, a programmable logic device, such as a programmable logic array, field programmable gate-array, or the like. In general, any device or devices capable of implementing the decision support method as described herein may be used to implement the decision support system functions of this disclosure.
