Embodiment Construction

[0020] Reference will now be made to some embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0021] figure 1 is a schematic diagram of a license assisted access (LAA) wireless system 100 with an improved method according to an embodiment of the present invention. The wireless communication system 100 includes one or more wireless communication networks, each of which has infrastructure elements, such as 102 and 104 . A base unit may also function as an access point, access terminal, base station, eNB, or other technologies used in the art. Each of base stations 102 and 104 serves a geographic area. The geographic areas served by wireless communication stations 102 and 104 overlap each other in this example.

[0022] The base station 102 is a licensed base station, which communicates with the UE 101 through a licensed frequency band. In one example, the base station 102 communicates with the UE 101 via LTE wireless communication...

Abstract

Periodic Radio Resource Management (RRM) reporting from user equipment (UE) is beneficial for a network to efficiently select a carrier with a cleaner channel to serve the UE. To enable periodic RRM reporting from the UE, periodic beacon signal transmission for UE measurements is necessary. However, in a shared spectrum, precise periodic transmission cannot be guaranteed due to channel contention. A method of transmission with periodic time windows for beacon signal transmission is proposed to resolve potential issues. Under the proposed solution, beacon signal can be transmitted in a certain periodic fashion without frequent physical layer signaling. Furthermore, periodic beacon signal transmission for measurements can be kept with low transmission failure rate due to channel contention.

Description

[0001] Cross References to Related Applications [0002] Scope of Claims of This Application Pursuant to 35 U.S.C. §119 priority is claimed to the following application: U.S. Provisional Case No. 62 / 133,742, filed March 16, 2015, entitled "Methods of Beacon Transmission for Measurements in Opportunistic Spectrum Access" . The entire contents of the aforementioned US Provisional Application are hereby incorporated by reference. technical field [0003] The present invention relates generally to wireless communications and, more particularly, to beacon signal transmission for measurements in grant-assisted access. Background technique [0004] 3GPP and Long Term Evolution (LTE) mobile telecommunication systems offer high data rates, low latency, and improved system performance. With the rapid development of IoT and other new types of UEs, the need to support a large number of machine-to-machine communications is growing exponentially. To meet this exponential growth in com...
