Coordinating spectrum authorization for backhaul connections
First Claim
1. A method for operating a first network node, the method comprising:
- registering each of the first network node and a second network node to a spectrum access system (SAS) by providing configuration information including at least location and radio capabilities for each of the respective network nodes;
sending to the SAS a request for radio resources and an authorization to transmit, the request requesting to establish a backhaul link on a shared radio spectrum between the first and second network nodes, wherein the configuration information and/or the request indicates the first network node and at least the second network node belong to a backhaul system;
in response to receiving a grant for radio resources on the shared spectrum and the authorization to transmit, broadcasting to the second network node the authorization to transmit providing the second network node authorization to transmit on the granted radio resources; and
using a reply, received from the second network node and in response to the broadcast, to establish the backhaul link between the first network node and the second network node.

Abstract
Configuration information including location and radio capabilities for first and second network nodes (for example, DeNB and RN respectively) are provided to register them to a spectrum access system (SAS). To establish a DeNB-RN backhaul link on a shared radio spectrum the DeNB sends the SAS a request for radio resources and authorization to transmit. The configuration information and/or the request indicates the DeNB and the RN belong to a backhaul system. The DeNB receives a grant for the radio resources and authorization, and broadcasts the authorization to the RN. The RN scans a broadcast channel while its receiver is active and its transmitter is inactive; detects the authorization to transmit, changes its transmitter from inactive to active, and transmits a reply to the DeNB'"'"'s broadcast. The RN'"'"'s reply to the DeNB'"'"'s broadcast is used to establish the backhaul link.

11. An apparatus comprising:
-
at least one computer readable memory storing computer program instructions; and at least one processor; wherein the computer readable memory with the computer program instructions is configured, with the at least one processor, to cause a first network node to at least; register each of the first network node and a second network node to a spectrum access system (SAS) by providing configuration information including at least location and radio capabilities for each of the respective network nodes; send to the SAS a request for radio resources and an authorization to transmit, the request requesting to establish a backhaul link on a shared radio spectrum between the first and second network nodes, wherein the configuration information and/or the request indicates the first network node and at least the second network node belong to a backhaul system; in response to receiving a grant for radio resources on the shared spectrum and the authorization to transmit, broadcast to the second network node the authorization to transmit providing the second network node authorization to transmit on the granted radio resources; and use a reply, received from the second network node and in response to the broadcast, to establish the backhaul link between the first network node and the second network node. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A computer readable memory storing computer program instructions that, when executed by one or more processors, cause a first network node to perform actions comprising:
-
registering each of the first network node and a second network node to a spectrum access system (SAS) by providing configuration information including at least location and radio capabilities for each of the respective network nodes; sending to the SAS a request for radio resources and an authorization to transmit, the request to establish a backhaul link on a shared radio spectrum between the first and second network nodes, wherein the configuration information and/or the request indicates the first network node and at least the second network node belong to a backhaul system; in response to receiving a grant for radio resources on the shared spectrum and the authorization to transmit, broadcasting to the second network node the authorization to transmit providing the second network node authorization to transmit on the granted radio resources; and using a reply, received from the second network node and in response to the broadcast, to establish the backhaul link between the first network node and the second network node.
