Problems solved by technology

However, while newer multiple-access systems (such as LTE or LTE-A systems) deliver faster data throughput compared to older technologies, this increased downlink rate has triggered Greater demand for higher bandwidth content such as high-resolution graphics and video used on the Internet or with mobile devices
As such, the demand for bandwidth over wireless communication systems continues to grow, however, the wireless spectrum is a limited and managed resource, especially when the wireless communication system includes multiple layers that may need to share the limited spectrum

Embodiment Construction

[0020] In some current implementations, multi-tier wireless communication systems may require a centralized database to allocate spectrum to operators or operating entities in different tiers. For example, a tier 1 operator may take absolute priority and have guaranteed resources allocated via the network (NW), while a tier 2 operator may take permission based allocation, typically with information embedded in a centralized database. Some layer 3 operational entities may share the remaining resources using listen before talk (LBT) or frequency allocation from a centralized database. However, using a centralized database for resource allocation may result in low network efficiency. Additionally, in some examples, a multi-layer wireless communication system may not provide incentives for layer 2 entities to participate, and may not allow layer 3 entities to share unused spectrum.

Abstract

Various aspects described herein relate to techniques of spectrum sharing in beacon-assisted multi-tier wireless communications systems (e.g., 5G New Radio). A method of spectrum sharing in multi-tierwireless communications is provided that may include generating, at a first apparatus, a beacon signal including information of spectrum usage, wherein the information includes at least one or more of a pilot reference, resources allocation, one or more usage entities, or one or more sharing parameters, and sending the beacon signal to at least a second apparatus, wherein the first apparatus andthe second apparatus are in a same tier or different tiers.
