## Abstract

A method, system and apparatus are disclosed. A network node configured to communicate with a wireless device is provided. The network node configured to, and/or comprising a radio interface and/or comprising processing circuitry configured to receive a unicast request message from a wireless device where the unicast request message includes information associated with a request for a unicast connection, and determine whether to permit establishment of the requested unicast connection based at least in part on the information in the unicast request message.

## Claims

### Claim 1

A network node for allocating a resource pool for use by a wireless device in device to device communications, the resource pool being one of a plurality of resource pools, each resource pool comprising one or more time and frequency resource, the network node comprising processing circuitry configured to:
obtain one or more properties associated with one of a unicast, multicast and broadcast connection, the obtained one or more properties being received from the wireless device in a request for configuration of the one of the unicast, multicast and broadcast connection, the request message indicating a preferred casting type, a casting type being one of unicast, multicast and broadcast;
determine whether the requested configuration can be established; and
allocate a resource pool per wireless device for the requested configuration based on the one or more properties and for the preferred casting type.

### Claim 2 (depends on 1)

The network node of claim 1, wherein the one or more properties are one or more of:
a wireless device location;
a wireless device capability;
a maximum power level for the unicast connection;
a quality of service level;
a global unicast connection identifier; and
a physical cell identifier of a cell that is in communication with the wireless device.

### Claim 3 (depends on 1)

The network node of claim 1, wherein the processing circuitry is further configured to indicate the allocated resource pool to the wireless device for one of autonomous resource allocation and network node scheduled resource allocation.

### Claim 4 (depends on 1)

The network node of claim 1, wherein the request message indicates a plurality of casting types, each casting type having a respective priority; and
the allocated resource pool being for one of the plurality of casting types.

### Claim 5 (depends on 4)

The network node of claim 4, wherein the plurality of casting types includes at least two of unicast, multicast and broadcast.

### Claim 6

A wireless device for using a resource pool for device to device communication, the resource pool being one of a plurality of resource pools, each resource pool corresponding to time and frequency resources, the wireless device comprising processing circuitry configured to:
cause transmission of a request message that indicates one or more properties for configuration of one of a unicast, multicast and broadcast connection and indicates a preferred casting type, a casting type is one of unicast, multicast and broadcast; and
receive an indication of an allocated resource pool, the resource pool being allocated to establish a unicast, multicast or broadcast connection for the wireless device and the resource pool being allocated based on one or more properties associated with the one of the unicast, multicast and broadcast connection, and the allocated resource pool being for the preferred casting type.

### Claim 7 (depends on 6)

The wireless device of claim 6, wherein the request message indicates a plurality of casting types, each casting type having a respective priority; and
the allocated resource pool being for one of the plurality of casting types.

### Claim 8 (depends on 7)

The wireless device of claim 7, wherein the plurality of casting types includes at least two of unicast, multicast and broadcast.

### Claim 9

A method implemented by a network node for allocating a resource pool for use by a wireless device in device to device communications, the resource pool being one of a plurality of resource pools, each resource pool comprising one or more time and frequency resource, the method comprising:
obtaining one or more properties associated with one of a unicast, multicast and broadcast connection, the obtained one or more properties being received from the wireless device in a request for configuration of the one of the unicast, multicast and broadcast connection, the request message indicating a preferred casting type, a casting type being one of unicast, multicast and broadcast;
determining whether the requested configuration can be established; and
allocating a resource pool per wireless device for the requested configuration based on the one or more properties and for the preferred casting type.

### Claim 10 (depends on 9)

The method of claim 9, wherein the one or more properties are one or more of:
a wireless device location;
a wireless device capability;
a maximum power level for the unicast connection;
a quality of service level;
a global unicast connection identifier; and
a physical cell identifier of a cell that is in communication with the wireless device.

### Claim 11 (depends on 9)

The method of claim 9, wherein the resource pool corresponds to another resource pool allocated to another wireless device.

### Claim 12 (depends on 9)

The method of claim 9, further comprising indicating the allocated resource pool to the wireless device for one of autonomous resource allocation and network node scheduled resource allocation.

### Claim 13 (depends on 9)

The method of claim 9, wherein the request message indicates a plurality of casting types, each casting type having a respective priority; and
the allocated resource pool being for one of the plurality of casting types.

### Claim 14 (depends on 9)

The method of claim 9, wherein the plurality of casting types includes at least two of unicast, multicast and broadcast.

### Claim 15 (depends on 9)

The method of claim 9, wherein the allocated resource pool is dedicated for use by the wireless device.

### Claim 16

A method implemented by a wireless device for using a resource pool for device to device communication, the resource pool being one of a plurality of resource pools, each resource pool corresponding to time and frequency resources, the method comprising:
transmitting a request message that indicates one or more properties for configuration of one of a unicast, multicast and broadcast connection and indicates a preferred casting type, a casting type being one of unicast, multicast and broadcast; and
receiving an indication of an allocated resource pool, the resource pool being allocated to establish a unicast, multicast or broadcast connection for the wireless device and the resource pool being allocated based on one or more properties associated with the one of the unicast, multicast and broadcast connection, and the allocated resource pool being for the preferred casting type.

### Claim 17 (depends on 16)

The method of claim 16, wherein one or more properties are one or more of:
a wireless device location;
a wireless device capability;
a maximum power level for the unicast connection;
a quality of service level;
