Embodiment Construction

[0018] The making and using of the presently preferred embodiments are discussed in detail below. It should be appreciated, however, that the present invention provides applicable innovative concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention. In view of the above, the present invention will be described in the specific context of apparatuses, methods and systems for efficiently allowing control of the transmitter power level of a user equipment participating in D2D communication using cellular communication spectrum of the system so that interference is managed between the two communication modes. The apparatus, method and system are applicable (non-limiting) to any communication system, including existing and future 3GPP technologies such as UMTS, LTE, and future variants thereof such as 4th generation (4G) ...

Abstract

An apparatus, method and system for controlling a transmitter power level for direct device-to-device communications in a communication system. In one embodiment, an apparatus includes a processor and memory including computer program code. The memory and the computer program code are configured to, with the processor, cause the apparatus to monitor a feedback message from a base station to a user equipment participating in cellular communications employing a communication resource, and control a transmitter power level for device-to-device ("D2D") communications employing the communication resource as a function of the feedback message.

Description

technical field [0001] The present invention relates generally to communication systems, and more particularly to apparatus, methods and systems for controlling transmitter power levels for device-to-device communications in a communication system. Background technique [0002] The 3rd Generation Partnership Project ("3GPP") Long Term Evolution ("LTE") (also referred to as 3GPP LTE) refers to research and development involving 3GPP Release 8 and beyond, and its name is often used to describe the Identifies industry-wide ongoing efforts that could improve the technology and capabilities of systems such as Universal Mobile Telecommunications System (UMTS). The term "LTE-A" is commonly used in the industry to refer to further enhancements in LTE. The goals of this broadly based project include improving communication efficiency, reducing costs, improving services, taking advantage of new spectrum opportunities, and enabling better integration with other open standards.
