Abstract

Claims (38)

1 . A method of transmitting over a radio access network to a base station, by a network entity, a radio resource control signalling indicating the capability of a user equipment to perform network coding, wherein the method comprises:

detecting by the network entity of a trigger event for signalling to the base station, the network coding capabilities of the user equipment;

generating by the network entity a radio resource control signalling message comprising the user equipment network coding capabilities;

transmitting by the network entity of the generated radio resource control signalling message to the base station; and

wherein the method further comprises:

transmitting a status report for reporting a change in its internal parameters upon detection of the change, the status report being transmitted within a message different from the message comprising the network coding capabilities.

2 . The method of claim 1 , wherein the method further comprises:

receiving by the network entity of a radio resource control signalling request from the base station, this reception constituting the trigger event.

3 . The method of claim 2 , wherein the method further comprises:

checking the need for network coding activation by the base station prior to transmitting the radio resource control signalling request to the network entity.

4 . The method of claim 1 , wherein the method further comprises:

detecting by the network entity of a status change of the network entity, this status change constituting the trigger event.

5 . The method according to claim 1 , wherein the method further comprises:

transmitting by the base station to a core network a radio resource control signalling message comprising the user equipment network coding capabilities.

6 . The method of claim 5 , wherein the method further comprises:

receiving by the base station of a radio resource control signalling request from the core network prior to the transmission of the radio resource control signalling message to the core network.

7 . The method of claim 5 , wherein the user equipment network coding capabilities are stored by the core network.

8 . The method of claim 1 , wherein the user equipment network coding capabilities comprise information indicating that the user equipment supports network coding processing.

9 . The method of claim 1 , wherein the user equipment network coding capabilities comprises information indicating the network coding scheme supported by the user equipment.

10 . The method of claim 9 , wherein the information indicating the network coding scheme is related to an information on packet data convergence protocol packet duplication capabilities.

11 . The method of claim 1 , wherein the user equipment network coding capabilities comprise information related to some network coding capability restrictions.

12 . The method of claim 1 , wherein the user equipment network coding capabilities comprise information indicating the support of network coding through multi-connectivity.

13 . The method of claim 1 , wherein the user equipment network coding capabilities comprise information indicating the support of network coding through carrier aggregation.

14 . The method of claim 1 , wherein the user equipment network coding capabilities comprise information indicating the support of network coding encoding, decoding, or encoding and decoding.

15 . The method of claim 1 , wherein the user equipment network coding capabilities comprise information indicating a maximum of supported streams on which network coding is applied.

16 . The method of claim 1 , wherein the user equipment network coding capabilities comprise information related to the processor capacity of the user equipment.

17 . The method of claim 1 , wherein the user equipment network coding capabilities comprise information indicating a temporary incapacity to perform network coding processing.

18 . The method of claim 1 , wherein the user equipment network coding capabilities comprise information of a class of the user equipment, the class being associated with a set of network coding capabilities.

19 . The method according to claim 1 , wherein the method further comprises:

activating by the base station of the network coding according to the capabilities of the user equipment to perform network coding.

20 . A non-transitory computer-readable storage medium storing instructions of a computer program for implementing a method according to claim 1 .

21 . A network entity device for transmitting over a radio access network to a base station, a radio resource control signalling indicating the capability of a user equipment to perform network coding, wherein the network entity device comprises a processor configured for:

detecting a trigger event for signalling to the base station, the network coding capabilities of the user equipment;

generating a radio resource control signalling message comprising the user equipment network coding capabilities; and

transmitting by the network entity of the generated radio resource control signalling message to the base station; and

wherein the method further comprises:

transmitting a status report for reporting a change in its internal parameters upon detection of the change, the status report being transmitted within a message different from the message comprising the network coding capabilities.

22 . The method of claim 1 , wherein the status report is a status report for updating an already stored network coding capabilities.
