Title: Transmitting apparatus, receiving apparatus, and communication system for formatting data

Abstract: A transmitting apparatus, a receiving apparatus, and a communication system are provided that allow a reduction in a frame loss due to interference caused by use of the same channel. A transmitting apparatus disposed in a base station includes a GPS receiver for receiving a GPS signal, a timing generator for controlling respective function blocks in accordance with the GPS signal and an inter-base-station control signal so as to precisely synchronize the timing of frame transmission among base stations, the front-end transmission processing unit including for converting transmission information into transmission time slots, a frame generator for generating a frame including a plurality of time slots and one frame guard, and a back-end transmission processing unit for transmitting the generated frame as a radio signal.

The First Claim: 1. A transmitting apparatus, in an orthogonal frequency division multiplexing wireless communication system, comprising: a front-end transmission processing unit for converting a transmission signal into a transmission time slot; a frame generator for generating a frame that includes a series of n (greater than 1) time slots and a frame guard period added to the series of n time slots, each time slot including an effective symbol period and guard period added to the effective symbol period, where the length of the series of n time slots is less than the length of the frame; and a back-end transmission processing unit for transmitting the generated frame as a radio signal.


Disclaimer: The promise of Apex Standards Claim Construction (CC) is that it will conduct the Broadest Reasonable, Ordinary, or Customary Interpretation for the claim elements of a target patent or the technical specification languages of an industrial standard. Therefore, a top-down, apriori evaluation is enabled, allowing stakeholders to swiftly and effectively analyze the relevance and scope of terms and phrases under consideration prior to making complex, high-value judgments. CC is intended to alleviate the initial burden of evidence by providing an exhaustive list of contextual semantic understandings that can be used as building blocks in the development of a prosecution-ready, licensing-ready, or litigation-ready work product. Stakeholders can then utilize the CC to revise the original claim or technical languages, as well as to find more relevant arts in order to build strategy and accomplish additional goals.
