Abstract

There is disclosed a D2D enabled node (10) for a wireless communication network, the D2D enabled node being adapted to perform a D2D operation on a first carrier frequency or band (f1) and a cellular operation on a second carrier frequency or band (f2). The D2D enabled node (10) is further adapted for obtaining information about D2D operation on f1 and obtaining information about cellular DL operation on f2, as well as being adapted for adapting at least one of the D2D operation and cellular DL operation to meet one or more requirements or to comply with one or more rules.

There are disclosed further related devices and methods.

Claims

1. A device-to-device (D2D)-enabled node for a wireless communication network, wherein:

the D2D-enabled node is configured to perform D2D communication with one or more other D2D-enabled nodes and is configured to perform a D2D operation on a first carrier frequency or band (f1) and a cellular operation on a second carrier frequency or band (f2);

the D2D-enabled node is further configured to obtain information about D2D operation on f1 and to obtain information about cellular downlink (DL) operation on f2, and is configured to adapt the D2D operation, based on the obtained information about D2D operation on f1 and the obtained information about cellular DL operation on f2, to meet one or more requirements or to comply with one or more rules;

wherein the obtained information about cellular DL operation on f2 comprises information identifying resource usage by cellular DL transmissions; and

wherein adapting the D2D operation comprises adjusting usage of resources for D2D operation to avoid at least some use of resources overlapping with cellular DL operation, based on the information identifying resource usage by cellular DL transmissions.

2. The D2D-enabled node of claim 1, wherein the adapting at the D2D operation that the D2D-enabled node is configured to do comprises at least one of:

establishing a time relation between f1 and f2;

determining the need for adaptation; and

adaptation.

3. The D2D-enabled node of claim 1, wherein the adapting the D2D operation that the D2D-enabled node is configured to do comprises adapting the receiver configuration while receiving system information.

4. The D2D-enabled node of claim 3, wherein the system information comprises at least one or more of:

a Master Information Block (MIB), a System Information Block 1 (SIB1), and another System Information Block (SIB).

5. A method performed by a device-to-device (D2D)-enabled node for a wireless communication network, the D2D-enabled node being adapted to perform D2D communication with one or more other D2D-enabled nodes, the method comprising:

performing a D2D operation on a first carrier frequency or band (f1) and a cellular operation on a second carrier frequency or band (f2);

obtaining information about D2D operation on f1 and obtaining information about cellular downlink (DL) operation on f2, wherein the obtained information about cellular DL operation on f2 comprises information identifying resource usage by cellular DL transmissions; and

adapting the D2D operation to meet one or more requirements or to comply with one or more rules, based on the obtained information about D2D operation on f1 and the obtained information about cellular DL operation on f2, to ensure a certain level of the cellular DL performance, wherein adapting the D2D operation comprises adjusting usage of resources for D2D operation to avoid at least some use of resources overlapping with cellular DL operation, based on the information identifying resource usage by cellular DL transmissions.

6. The method of claim 5, wherein the adapting comprises at least one of:

establishing a time relation between f1 and f2;

determining the need for adaptation; and

adaptation.

7. The method of claim 5, wherein the adapting comprises adapting the receiver configuration while receiving system information.

8. The method of claim 7, wherein the system information comprises at least one or more of:

a Master Information Block (MIB), a System Information Block 1 (SIB1), and another System Information Block (SIB).

9. A method performed by a device-to-device (D2D)-enabled node for a wireless communication network, the D2D-enabled node being adapted to perform D2D communication with one or more other D2D-enabled nodes, the method comprising:

performing a D2D operation on a first carrier frequency or band (f1) and a cellular operation on a second carrier frequency or band (f2);

obtaining information about D2D operation on f1 and obtaining information about cellular downlink (DL) operation on f2, wherein the obtained information about cellular DL operation on f2 comprises information identifying resource usage by cellular DL transmissions; and

adapting the cellular DL operation to meet one or more requirements or to comply with one or more rules, based on the obtained information about D2D operation on f1 and the obtained information about cellular DL operation on f2, to ensure a certain level of the cellular DL performance, wherein adapting the cellular DL operation comprises adjusting timing of cellular DL operation to avoid at least some use of resources overlapping with D2D operation, based on the information identifying resource usage by cellular DL transmissions.
