## Abstract

A technique, comprising: controlling a radio transmitter or radio transceiver of a device of a first radio system to transmit to a second radio system information about use of at least one radio resource for one or more transmissions outside the control of the second radio system, wherein said at least one radio resource is also usable for transmissions controlled by the second radio system.

## Claims

### Claim 1

A method comprising:
transmitting, by a user device, a random access preamble message as an access request to a node controlling a radio access network, the message including a device identifier indicating that the user device has information regarding grant or denial of permission to the radio access network, the permission regarding use of at least one radio resource for transmissions outside control of the node controlling the radio access network, the at least one radio resource being shared under an authorized access scheme;
establishing a radio connection as a response to the node accepting the access request; and
after establishing the radio connection, transmitting the information regarding grant or denial of permission to the radio access network for use of the at least one radio resource for an authorized shared access controller controlling the use of the at least one radio resource.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the at least one radio resource is primarily licensed for use outside the control of the node.

### Claim 3 (depends on 1)

The method according to claim 1, wherein the at least one radio resource is primarily licensed for use outside the control of the node and the use outside the control of the node has a higher priority over the use of the at least one radio resource as controlled by the node.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the at least one radio resource comprises one or more radio frequency bands shared under an authorized shared access scheme.

### Claim 5 (depends on 1)

The method according to claim 1, wherein transmitting the random access preamble message and transmitting the information regarding grant or denial of permission to the radio access network for use of the at least one radio resource are carried out by using statically defined or pre-configured bearers.

### Claim 6

An apparatus comprising: a processor and memory including computer program code, wherein the memory and computer program code are configured to, with the processor, cause the apparatus to:
transmit, by a user device, a random access preamble message as an access request to a node controlling a radio access network, the message including a device identifier indicating that the user device has information regarding grant or denial of permission to the radio access network, the permission regarding use of at least one radio resource for transmissions outside control of the node controlling the radio access network, the at least one radio resource being shared under an authorized access scheme;
establish a radio connection as a response to the node accepting the access request; and
after establishing the radio connection, transmit the information regarding grant or denial of permission to the radio access network for use of the at least one radio resource for an authorized shared access controller controlling the use of the at least one radio resource.

### Claim 7 (depends on 6)

The apparatus according to claim 6, wherein the at least one radio resource is primarily licensed for use outside the control of the node.

### Claim 8 (depends on 6)

The apparatus according to claim 6, wherein the at least one radio resource is primarily licensed for use outside the control of the node and the use outside the control of the node has a higher priority over the use of the at least one radio resource as controlled by the node.

### Claim 9 (depends on 6)

The apparatus according to claim 6, wherein the at least one radio resource comprises one or more radio frequency bands shared under an authorized shared access scheme.

### Claim 10 (depends on 6)

The apparatus according to claim 6, wherein the memory and computer program code being configured to, with the processor, cause the apparatus to transmit the random access preamble message and transmit the information regarding grant or denial of permission to the radio access network for use of the at least one shared radio resource comprises the memory and computer program code being configured to, with the processor, cause the apparatus to transmit the random access preamble message and transmit the information regarding grant or denial of permission to the radio access network for use of the at least one radio resource by using statically defined or pre-configured bearers.
