Abstract

The present invention relates to method for communicating in a network comprising the step a) of a primary station transmitting to at least one secondary station on a downlink control channel an indication related to a resource allocated to said secondary station in accordance with a semi persistent schedule, wherein the step a) comprises the step of transmitting to the secondary station at least two messages including at least part of the indication in one subframe.

Claims

1. A method for communicating in a network comprising the step a) of a primary station transmitting to at least one secondary station on a control channel an indication related to a resource allocated to said secondary station in accordance with a semi persistent schedule, wherein the step a) comprises the step of transmitting to the secondary station at least two messages including at least part of the indication in one subframe.

2. The method of claim 1, wherein the allocated resource is one of a downlink resource to be used by the primary station or an uplink resource to be used by the secondary station.

3. The method of claim 1, wherein one message to a secondary station relates to an allocated resource which is an uplink resource to be used by the said secondary station and another message to the said secondary station relates to an allocated resource which is a downlink resource to be used by the primary station for transmitting to the said secondary station.

4. The method of claim 1, wherein the two messages are identical.

5. The method of claim 1, wherein each message comprises a message identifier identifying each message, and wherein the message identifiers of the two messages are equal.

6. The method of claim 5, wherein the message identifiers are encoded in a cyclic redundancy check, and wherein the two messages comprise the same cyclic redundancy check.

7. The method of claim 1, wherein each message comprises a message identifier identifying each message, and wherein a first message of the at least two messages comprises a first identifier, and wherein a second message of the at least two messages comprises a second identifier, being different from the first identifier.

8. The method of claim 7, wherein the first identifier is an identifier identifying a signaling message, and wherein the second identifier is an identifier assigned to the secondary station.

9. The method of claim 8, wherein if the secondary station receives only the first message, the secondary station prevents itself from transmitting a data packet.

10. The method of claim 8, wherein if the secondary station receives only the first message, the secondary station uses the reception of the second message as a time reference.

11. The method of claim 8, wherein the two messages are transmitted simultaneously.

12. The method of claim 1, wherein a first message of the at least two messages and a second message of the at least two messages comprises respectively a first part and a second part of a cyclic redundancy check, and further comprising the secondary station recombining the first and second parts into the cyclic redundancy check upon reception of the first and second messages.

13. A primary station comprising means for communicating with at least one secondary station, wherein the primary station comprises a transmitter for transmitting the secondary station on a control channel an indication related to a resource allocated to said secondary station in accordance with a semi persistent schedule, wherein the transmitter is arranged to transmit to the secondary station at least two messages including at least part of the indication in one subframe.

14. A secondary station comprising means for communicating with at least one primary station, the secondary station comprising a receiver for receiving from the primary station on a control channel an indication related to a resource allocated to said secondary station in accordance with a semi persistent schedule, wherein the secondary station is arranged for receiving within one subframe at least two messages including each at least part of the indication.

15. A communication system comprising a primary station communicating with at least one secondary station, wherein the primary station comprises a transmitter for transmitting to the at least one secondary station on a control channel an indication related to a resource allocated to said secondary station in accordance with a semi persistent schedule, wherein the transmitter is arranged to transmit within one subframe to the secondary station at least two messages including at least part of the indication.
