Abstract

The invention relates to a method and apparatuses for allocating radio resources in a cellular communications network including the steps of: dynamically allocating a set of radio resources for a transmission taking place at a transmission time instance and for a further transmission taking place at a further transmission time instance, the further transmission relating to a response to the transmission taking place at the transmission time instance, and broadcasting both sets of allocated radio resources in the cellular communications network.

Claims

1. A method for allocating radio resources in a cellular communications network comprising:

dynamically allocating a set of radio resources for a transmission taking place at a transmission time instance (N) and for a further transmission taking place at a further transmission time instance (N+k), the further transmission relating to a response to the transmission taking place at the transmission time instance (N), wherein the response comprises a feedback message, wherein the feedback message is an ACK or a NACK message, and wherein any data present at the further transmission time instance (N+k) is multiplexed together with data relating to the response to be transmitted at the further transmission time instance (N+k); and

broadcasting both sets of allocated radio resources in the cellular communications network.

2. The method of claim 1, wherein the feedback message further comprises of one or more ACK or NACK messages.

3. The method of claim 1, wherein both sets of allocated radio resources are comprised within a broadcasted downlink configuration indicator.

4. The method of claim 1, wherein if the transmission is transmitted on a Physical Download Shared Channel, the further transmission is transmitted on a Physical Uplink Shared Channel or a Physical Uplink Control Channel.

5. The method of claim 1, wherein if the transmission is transmitted on a Physical Uplink Shared Channel, the further transmission is transmitted on a Physical Downlink Shared Channel or on a Physical Hybrid ARQ Indicator Channel.

6. The method of claim 1, wherein the multiplexed data further comprises downlink physical hybrid ARQ indicator information multiplexed on the Physical Downlink Shared Channel.

7. The method of claim 6, wherein the downlink physical hybrid ARQ indicator information is transmitted with a downlink demodulation reference signal.

8. The method of claim 7, wherein the downlink physical hybrid ARQ indicator information is demodulated based on the transmitted downlink demodulation reference signal.

9. The method of claim 1, wherein the cellular communications network is a centralised radio access network.

16. A computer program product embodied on a non-transitory computer-readable medium in which a computer program is stored that, when being executed by a computer, is configured to provide instructions to control or carry out the method of claim 1.

10. An access node in a cellular communications network comprising:

a microprocessor programmed to dynamically allocated a set of radio resources for a transmission taking place at a transmission time instance (N) and for a further transmission taking place at a further transmission time instance (N+k), the further transmission relating to a response to the transmission taking place at the transmission time instance (N), wherein the response comprises a feedback message, wherein the feedback message is an ACK or a NACK message, and wherein any data present at the further transmission time instance (N+k) is multiplexed together with data relating to the response to be transmitted at the further transmission time instance (N+k); and

a transceiver configured to broadcast both sets of allocated radio resources in the cellular communications network.

11. The access node of claim 10, wherein the transceiver is further configured to broadcast both sets of allocated radio resources within a downlink configuration indicator.

12. The access node of claim 10, wherein the access node is at least one of the following:

a base station, an eNodeB.

15. The access node of claim 10 in a cellular communications network and at least one user equipment comprising:

a receiver configured to receive a broadcast comprising a set of allocated radio resources for a transmission taking place at a transmission time instance (N) and for a further transmission taking place at a further transmission time instance (N+k), the further transmission relating to a response to the transmission taking place at the transmission time instance (N), and

a transmitter configured to transmit the further data transmission at the further transmission time instance (N+k).

13. A user equipment comprising:

a receiver configured to receive a broadcast comprising a set of allocated radio resources for a transmission taking place at a transmission time instance (N) and for a further transmission taking place at a further transmission time instance (N+k), the further transmission relating to a response to the transmission taking place at the transmission time instance (N), wherein the response comprises a feedback message, wherein the feedback message is an ACK or a NACK message, and wherein any data present at the further transmission time instance (N+k) is multiplexed together with data relating to the response to be transmitted at the further transmission time instance (N+k); and

a transmitter configured to transmit the further data transmission at the further transmission time instance (N+k).

14. The user equipment of claim 13, further comprising:

a multiplexer configured to multiplex data to be transmitted together with data relating to the feedback message at the further transmission time instance (N+k).
