摘要

A method and apparatus are disclosed from the perspective of a UE (User Equipment). In one embodiment, the method includes the UE monitors or receives a control signal within a channel occupancy, wherein the control signal indicates a number of consecutive TTIs (Transmission Time Intervals) and TTI format(s) related information of the TTIs. The method further includes the UE derives transmission direction of symbols in the TTIs or functionality of symbols in the TTIs from the information. The method also includes the UE considers the last TTI of the indicated TTIs as an ending TTI of the channel occupancy. In addition, the method includes the UE performs DL (Downlink) data reception or UL (Uplink) data transmission until the ending TTI.

說明書

In addition, the various illustrative logical blocks, modules, and circuits described in connection with the aspects disclosed herein may be implemented within or performed by an integrated circuit (“IC”), an access terminal, or an access point. The IC may comprise a general purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, electrical components, optical components, mechanical components, or any combination thereof designed to perform the functions described herein, and may execute codes or instructions that reside within the IC, outside of the IC, or both. A general purpose processor may be a microprocessor, but in the alternative, the processor may be any conventional processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices, e.g., a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration.

It is understood that any specific order or hierarchy of steps in any disclosed process is an example of a sample approach. Based upon design preferences, it is understood that the specific order or hierarchy of steps in the processes may be rearranged while remaining within the scope of the present disclosure. The accompanying method claims present elements of the various steps in a sample order, and are not meant to be limited to the specific order or hierarchy presented.
