Embodiment Construction

[0050] The detailed description, set forth below in connection with the accompanying drawings, is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of various concepts. It will be apparent, however, to one skilled in the art that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring such concepts.

[0051] Regarding synchronous communication, it may be good for link efficiency, but has an associated cost. For example, at a receiver, synchronous communications may require the receiver to acquire, track and correct timing before data can be received. At the transmitter, and after the receiver has had timing configured, the transmitter m...

Abstract

Apparatuses and methods for performing asynchronous multicarrier communications are provided. One such method involves generating, at a first wireless device, a waveform including one or more carriers, shaping the waveform to reduce interference between the waveform and adjacent waveforms, and transmitting, on a spectrum, the shaped waveform asynchronously.

Description

[0001] priority claim [0002] This application claims priority and the benefit of U.S. Provisional Application No. 62 / 004,337, filed May 29, 2014, and U.S. Nonprovisional Application No. 14 / 574,149, filed December 17, 2014, as if fully set forth below , and for all applicable purposes, the entire contents of said provisional application and non-provisional application are hereby incorporated by reference. technical field [0003] Aspects of the present disclosure relate generally to wireless communication systems, and more specifically, to asynchronous multi-carrier communication. Background technique [0004] Wireless communication networks are widely deployed to provide various communication services such as telephony, video, data, messaging, broadcast, and so on. Such networks, typically multiple-access networks, support communications for multiple users via sharing of available network resources. [0005] As the demand for mobile broadband access continues to grow, re...
