Embodiment Construction

[0033] The detailed description, set forth below in connection with the accompanying figures, 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 implemented. 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.

[0034] In Long Term Evolution (LTE) networks, a subcarrier spacing of 15 KHz is used. A subcarrier spacing of 15KHz is suitable for the transmission of synchronization signals (eg, PSS and SSS), PBCH, RS, and other signals including control and data signals. Using one subcarrier spacing for all types of signals may affect the performance ...

Abstract

The present disclosure provides an example method and an apparatus for transmitting synchronization signals from an eNB with a different subcarrier spacing from rest of transmissions. That is, a primary synchronization signal (PSS), a secondary synchronization signal (SSS) may be transmitted using a first subcarrier spacing, a physical broadcast channel (PBCH), and / or a reference signal (RS) may be transmitted with a second subcarrier spacing, and other transmissions may be made using a third subcarrier spacing that is different from at least one of the first or second subcarrier spacing. Further, the order of symbols mapped to the synchronization signals may be reversed or otherwise modified within a transmission subframe.

Description

[0001] Cross References to Related Applications [0002] This patent application claims U.S. Nonprovisional Application No. 15 / 824,753, filed November 28, 2017, entitled "SYNCHRONIZATION SIGNALOPTIONS FOR 5G / NEW RADIO," and filed November 30, 2016, entitled "SYNCHRONIZATION SIGNALOPTIONS OPTIONS FOR 5G / NEW RADIO" of U.S. Provisional Application No. 62 / 428,185, which is assigned to the assignee of the present application and is hereby incorporated by reference in its entirety. Background technique [0003] The present disclosure relates generally to signaling in wireless networks, and more particularly to the transmission of synchronization signals in wireless networks. [0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcast. A typical wireless communication system may employ a multiple access technology capable of supporting communication with multiple users by sharing a...
