Embodiment Construction

[0048] The detailed description set forth below in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to limit the scope of the present disclosure. Rather, the detailed description includes specific details in order to provide a comprehensive understanding of the inventive subject matter. It will be apparent to those skilled in the art that these specific details are not required in every instance, and in some instances, well-known structures and components are shown in block diagram form for clarity of presentation.

[0049] Techniques are described in which a license-exempt radio frequency band is used for at least a portion of contention-based communications over a wireless communications system. In some examples, contention-based shared radio frequency bands may be used for LTE communications or LTE-Advanced (LTE-A) communications. Competition-based radio frequency bands may be used in conjunction with or ...

Abstract

A method and apparatus for wireless communication in the unlicensed spectrum between an eNB and UE having different bandwidths, e.g., between narrowband UE and a wideband eNB are provided. A user equipment apparatus segments an uplink duration in each frame into multiple transmission units for each frequency, wherein a frame comprises an integer number of the transmission units. The apparatus transmits uplink communication based on the multiple transmission units, wherein each transmission unit comprises at least one on period and at least one off period corresponding to each of a plurality offrequencies, during an on period the UE transmits uplink communication on the corresponding frequency and during an off period the UE refrains from transmitting uplink communication on the corresponding frequency. Each transmission unit may comprise multiple on periods and multiple off periods. The on / off periods may be configured by a base station or specified for each frame type.

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Application Serial No. 62 / 416,651, filed November 2, 2016, entitled "WIRELESS COMMUNICATION BETWEENWIDEBAND ENB AND NARROWBAND UE," and filed June 27, 2017, entitled "WIRELESS COMMUNICATION BETWEEN WIDEBAND ENB AND NARROWBANDUE," US Patent Application No. 15 / 635,018, which is expressly incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates generally to communication systems, and more particularly to wireless communication between base stations and user equipment (UEs) having different bandwidths (eg, between a broadband base station and a narrowband UE). Background technique [0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcast. Typical wireless communication systems may employ multiple access techniques capable of suppo...
