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 an 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 disclosed. A basestation apparatus performs an LBT procedure at a beginning of frames and transmits a plurality of repetitions of a transmission. When the plurality of repetitions span multiple frames and the LBT procedure is not successful for a first frame, the base station drops or postpones at least one repetition in the first frame until a second frame when the LBT procedure is successful. UE receives the plurality of repetitions and may combine a plurality of repetitions across multiple frames. The UE may determine whether the base station drops the at least one repetition in the first frame or postponesthe at least one repetition in the first frame until a second frame.

Description

[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 / 635,051, 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...
