Control channel for positioning related data
According to an aspect, a method is provided of operating a wireless communication device (UE) to provide positioning related data for determining a position estimate of the UE, the UE being connected to a communications network via a radio link, the method comprising: monitoring for a control channel associated with a positioning occasion in which the UE monitors for at least one positioning reference signal, wherein the control channel comprises an allocation configuration of resources for transmitting the positioning related data. According to further aspects, a method of operating a wireless communication device, a wireless communication device and an access node are provided.
1. A method of operating a user equipment (UE) to provide positioning related data for determining a position estimate of the UE, the UE being connected to a communications network via a radio link, the method comprising:
monitoring for a control channel associated with a positioning occasion in which positioning occasion the UE monitors for at least one positioning reference signal,
wherein the monitoring for the control channel occurs at least one of before, during, or after the positioning occasion, and
in the case that the monitoring for the control channel occurs during the positioning occasion, also monitoring for the control channel at least one of before or after monitoring for a predetermined positioning reference signal, in particular a first or last positioning reference signal of the positioning occasion,
wherein the control channel comprises an allocation configuration of resources for transmitting the positioning related data.
2. The method of claim 1 , comprising
transmitting positioning related data using at least one of the resources according to the allocation configuration.
3. The method of claim 1 ,
wherein the positioning related data comprises an indication that further resources for transmitting positioning related data are required.
4. The method of claim 1 ,
wherein the positioning related data comprises an indication that no further resources for transmitting positioning related data are required.
5. The method of claim 1 ,
wherein the control channel comprises an indication of resources to be activated, by the UE, for receiving positioning reference signals.
6. The method of claim 1 ,
wherein the control channel comprises an indication to start, pause, continue or stop positioning measurements.
7. The method of claim 1 ,
wherein the positioning related data comprises measurement data and/or a positioning estimate.
8. The method of claim 1 ,
wherein the control channel is encoded with a temporary ID.
9. The method of claim 8 ,
wherein the temporary ID is associated with the UE or wherein the temporary ID is associated with a group of UEs including the UE.
10. The method of claim 1 , further comprising
monitoring for multiple control channels associated with the positioning occasion.
11. A method of operating an access node (AN) for receiving positioning related data for determining a position estimate of a user equipment (UE) the UE being connected to a communications network via a radio link between the UE and the AN, the method comprising:
transmitting a control channel associated with a positioning occasion in which positioning occasion the UE monitors for at least one positioning reference signal,
wherein the monitoring for the control channel occurs at least one of before, during, or after the positioning occasion, and
in the case that the monitoring for the control channel occurs during the positioning occasion, also monitoring for the control channel at least one of before or after monitoring for a predetermined positioning reference signal, in particular a first or last positioning reference signal of the positioning occasion,
wherein the control channel comprises an allocation configuration of resources for transmitting the positioning related data.
12. The method of claim 11 , comprising
receiving positioning related data using at least one of the resources according to the allocation configuration.
13. The method of claim 11 ,
wherein the positioning related data comprises an indication that further resources for transmitting positioning related data are required.
14. The method of claim 11 ,
wherein the positioning related data comprises an indication that no further resources for transmitting positioning related data are required.
15. The method of claim 11 ,
wherein the control channel comprises an indication of resources to be activated, by the UE, for receiving positioning reference signals.
16. The method of claim 11 ,
wherein the control channel comprises an indication to start, pause, continue or stop positioning measurements.
