Abstract
The present disclosure provides a method in a first terminal device. The method includes: initiating a first transmission on a first resource; reserving a second resource for a second transmission; and initiating the second transmission on the second resource. The first resource and the second resource are separated by at least a time gap to enable a second terminal device that is to reserve or has reserved the second resource to trigger a resource reselection in response to sensing the first transmission within the time gap.
Claims20
A method in a first terminal device, comprising:
- initiating a first transmission on a first resource, and
- reserving a second resource for a second transmission,
- wherein the first resource and the second resource are separated by at least a time gap to enable the first terminal device to receive a coordination message from a second terminal device within the time gap;
- the method further comprising:
- receiving the coordination message from the second terminal device within the time gap.
A method in a second terminal device, comprising:
- receiving a transmission from a first terminal device on a first resource and a reservation for a second resource for a retransmission by the first terminal device;
- and
- transmitting, to the first terminal device, a Hybrid Automatic Repeat reQuest, HARQ, Negative Acknowledgement, NACK, and a coordination message, wherein the HARQ NACK is associated with the transmission and the coordination message contains a request for a resource reselection or pre-emption at the first terminal device;
- wherein the coordination message is transmitted within a time gap the first resource and the second resource are separated by at least the time gap.
A first terminal device, comprising a transceiver, a processor and a memory, the memory comprising instructions executable by the processor whereby the first terminal device is operative to:
- initiate a first transmission on a first resource, and
- reserve a second resource for a second transmission,
- wherein the first resource and the second resource are separated by at least a time gap to enable the first terminal device to receive a coordination message from a second terminal device within the time gap;
- the first terminal device is further operative to:
- receiving the coordination message from the second terminal device within the time gap.
