Shared spectrum operation is disclosed for sharing spectrum among multiple wireless deployments. Coordination procedures between and among 2nd and 3rd Tier deployments include the use of beacons transmitted by the 2nd Tier for clearing access to spectrum occupied by 3rd Tier users and multiple 3rd Tier deployments sharing resources using a group-listen before talk (LBT) protocol, rather than a per-node LBT protocol. The 2nd Tier beacon signals are transmitted to alert 3rd Tier users of their presence, which, upon detection, will leave the particular spectrum within a predetermined time. For the shared LBT protocol, the 3rd Tier deployments share the channel with each other through an LBT with random backoff, in which the start time of clear channel assessment (CCA) procedure and the random backoff values are synchronized among nodes of the same deployment.

Field
Aspects of the present disclosure relate generally to wireless communication systems, and more particularly, to shared spectrum operation among multiple tiers of users.
Background
FIG. 1 is a block diagram illustrating details of a wireless communication system.
FIG. 2 is a block diagram conceptually illustrating a design of a base station/eNB and a UE configured according to one aspect of the present disclosure.
FIG. 3 illustrates a block diagram illustrating a multi-tiered communication system.
The detailed description set forth below, in connection with the appended drawings, is intended as a description of various possible configurations and is not intended to limit the scope of the disclosure. Rather, the detailed description includes specific details for the purpose of providing a thorough 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 case and that, in some instances, well-known structures and components are shown in block diagram form for clarity of presentation.
This disclosure relates generally to providing or participating in authorized shared access between two or more wireless communications systems, also referred to as wireless communications networks. In various embodiments, the techniques and apparatus may be used for wireless communication networks such as code division multiple access (CDMA) networks, time division multiple access (TDMA) networks, frequency division multiple access (FDMA) networks, orthogonal FDMA (OFDMA) networks, single-carrier FDMA (SC-FDMA) networks, LTE networks, GSM networks, as well as other communications networks. As described herein, the terms “networks” and “systems” may be used interchangeably.
A CDMA network may implement a radio technology such as universal terrestrial radio access (UTRA), cdma2000, and the like. UTRA includes wideband-CDMA (W-CDMA) and low chip rate (LCR). CDMA2000 covers IS-2000, IS-95, and IS-856 standards.
