System and method for uplink panel selection with power saving
Some embodiments of this disclosure include apparatuses and methods for uplink panel selection with power saving. In some embodiments, user equipment (UE) may experience a positional change. In response, the UE may deactivate a first communication panel to save power and activate a second communication panel. The UE may then transmit a status message to a communication node indicating the activation and/or deactivation. The node may then register this activation and/or deactivation. In some embodiments, the node may monitor uplink slots from the first and second communication panel to identify the activation and deactivation. For example, if the node detects an absence of an uplink signal within a slot threshold, the node may identify the panel as being deactivated. The node may establishing communications with another panel based on a detected signal and/or the status message.
1. A method, comprising:
communicating with a user equipment (UE) via a first communication panel of the UE;
monitoring uplink slots from the first communication panel;
detecting, within a slot threshold of a current slot, an absence of an uplink signal in the monitored uplink slots, wherein the slot threshold comprises a number of the monitored uplink slots occurring before the current slot;
in response to the detecting, registering the first communication panel as being deactivated; and
establishing communications with the UE via a second communication panel of the UE.
2. The method of claim 1 , wherein the slot threshold is a value in milliseconds.
3. The method of claim 1 , wherein the absence of the uplink signal includes an absence of a scheduled transmission from the first communication panel.
4. The method of claim 1 , wherein the absence of the uplink signal includes an absence of a beam reporting.
5. The method of claim 1 , wherein the establishing further comprises:
receiving a status message from the UE indicating activation of the second communication panel; and
registering the second communication panel as being activated.
6. The method of claim 5 , wherein the status message includes a scheduling offset indicating a delay for activating the second communication panel.
7. The method of claim 5 , wherein the status message is a bit map.
8. The method of claim 5 , wherein the status message includes a beam reporting.
9. The method of claim 8 , wherein the beam reporting includes a measured panel index.
10. The method of claim 5 , wherein the status message includes a panel ID of the second communication panel.
11. An apparatus, comprising:
radio front end circuitry; and
processing circuitry coupled to radio front end circuitry, wherein the processing circuitry is configured to:
communicate with a user equipment (UE) via the radio front end circuitry and via a first communication panel of the UE;
monitor uplink slots from the first communication panel;
detect, within a slot threshold of a current slot, an absence of an uplink signal in the monitored uplink slots, wherein the slot threshold comprises a number of the monitored uplink slots occurring before the current slot;
in response to the detecting, register the first communication panel as being deactivated; and
establish communications with the UE via the radio front end circuitry and via a second communication panel of the UE.
12. The apparatus of claim 11 , wherein the slot threshold is a value in milliseconds.
13. The apparatus of claim 11 , wherein the absence of the uplink signal includes an absence of a scheduled transmission from the first communication panel.
14. The apparatus of claim 11 , wherein the absence of the uplink signal includes an absence of a beam reporting.
15. The apparatus of claim 11 , wherein to establish the communications via the second communication panel, the processing circuitry is further configured to:
receive a status message from the UE indicating activation of the second communication panel; and
register the second communication panel as being activated.
16. The apparatus of claim 15 , wherein the status message includes a scheduling offset indicating a delay for activating the second communication panel.
17. The apparatus of claim 15 , wherein the status message is a bit map.
18. The apparatus of claim 15 , wherein the status message includes a beam reporting.
19. The apparatus of claim 18 , wherein the beam reporting includes a measured panel index.
20. The apparatus of claim 15 , wherein the status message includes a panel ID of the second communication panel.
