Abstract

Claims (32)

1. A wireless device, WD, configured to communicate with a network node, the WD comprising a radio interface configured to:

receive a downlink control information, DCI, signal in a first slot, the DCI being configured to cause the WD to at least one of transmit uplink shared channel transmissions to the network node and receive downlink shared channel transmissions from the network node, the at least one of the transmitting and receiving being according to a pattern of a plurality of slots, the pattern comprising:

at least one of a pattern of uplink shared channel slots and downlink shared channel slots; and

gaps between successive at least ones of uplink shared channel transmissions and downlink shared channel receptions; and

at least one of transmit the uplink shared channel transmissions to the network node and receive the downlink shared channel transmissions from the network node according to the pattern, the at least one of the transmitting and receiving of at least one of the uplink and downlink shared channel transmissions in each slot being in a number of layers indicated by a rank provided by the DCI signal.

2. The WD of claim 1 , wherein the at least one of the transmitting and receiving uses different transport blocks, TBs, in each of at least two slots.

3. The WD of claim 2 , wherein different TBs have at least one of different hybrid automatic repeat request, HARQ, identifications and different payload content.

4. The WD of claim 1 , wherein the DCI is configured to cause the WD to transmit and receive according to the pattern without increasing a size of the DCI.

5. The of claim 1 , wherein the pattern is indicated by a control signal from the network node to the WD, the control signal being one of the DCI signal, a radio resource control, RRC, signal and a medium access, MAC, control element, CE, signal.

6. The WD of claim 1 , wherein the pattern is an alternating pattern of uplink shared channel transmissions and downlink shared channel receptions.

7. The WD of claim 1 , wherein the pattern includes a first block of successive downlink shared channel reception followed by a second block of successive uplink shared channel transmissions.

8. The WD of claim 1 , further comprising processing circuitry configured to allocate a first set of like time-frequency resources to each of the uplink shared channel transmissions and allocate a second set of like time-frequency resources to each of the downlink shared channel transmissions.

9. A method in a wireless device, WD, configured to communicate with a network node, the method comprising:

receiving a downlink control information, DCI, signal in a first slot, the DCI being configured to cause the WD to at least one of transmit uplink shared channel transmissions to the network node and receive downlink shared channel transmissions from the network node, the at least one of the transmitting and receiving being according to a pattern of a plurality of slots, the pattern comprising:

at least one of a pattern of uplink shared channel slots and downlink shared channel slots; and

gaps between successive at least ones of uplink shared channel transmissions and downlink shared channel receptions; and

at least one of transmitting the uplink shared channel transmissions to the network node and receiving the downlink shared channel transmissions from the network node according to the pattern, the at least one of the transmitting and receiving of at least one of the uplink and downlink shared channel transmissions in each slot being in a number of layers indicated by a rank provided by the DCI signal.

10. The method of claim 9 , wherein the at least one of the transmitting and receiving uses different transport blocks, TBs, in each of at least two slots.

11. The method of claim 10 , wherein the different TBs have at least one of different hybrid automatic repeat request, HARQ, identifications and different payload content.

12. The method of claim 9 , wherein the DCI is configured to cause the WD to transmit and receive according to the pattern without increasing a size of the DCI.

13. The method of claim 9 , wherein the pattern is indicated by a control signal from the network node to the WD, the control signal being one of the DCI signal, a radio resource control, RRC, signal and a medium access, MAC, control element, CE, signal.

14. The method of claim 9 , wherein the pattern is an alternating pattern of uplink shared channel transmissions and downlink shared channel receptions.

15. The method of claim 9 , wherein the pattern includes a first block of successive downlink shared channel reception followed by a second block of successive uplink shared channel transmissions.

16. The method of claim 9 , further comprising allocating a first set of like time-frequency resources to each of the uplink shared channel transmissions and allocate a second set of like time-frequency resources to each of the downlink shared channel transmissions.

17. The method of claim 9 , wherein the DCI signal indicates whether a Hybrid Automatic Repeat Request, HARQ, process is to contain a different transport block, TB, than a previously transmitted TB.

18. A method in a network node configured to communicate with a wireless device, WD, the method comprising:

determining a pattern of at least one of uplink and downlink shared channel transmissions to be scheduled by the WD in response to a downlink control information, DCI, signal of a plurality of slots, the pattern comprising:

at least one of a pattern of uplink shared channel slots and downlink shared channel slots; and

gaps between successive at least ones of uplink shared channel transmissions and downlink shared channel receptions;

signaling to the WD a signal that includes a rank and that configures the WD to at least one of receive downlink shared channel transmissions and uplink shared channel transmissions according to the determined pattern and in layers indicated by the rank;

scheduling the at least one of the uplink and downlink shared channel transmissions according to the determined pattern; and

allocating like time-frequency resources to each of the at least one of the uplink and downlink shared channel transmissions.
