System and method for communications with multi-antenna panel devices
A method for operating a user equipment with multi-beam communication capability includes performing measurements in accordance with received reference signals, and determining that at least one antenna panel is unused, wherein the determining is in accordance with the measurements, and based thereon, reporting an availability of the at least one antenna panel.

performing, by the UE, measurements of received reference signals;
determining, by the UE in accordance with the measurements of the received reference signals, that at least one antenna panel, which is currently-assigned to one radio link monitoring (RLM) task, is available for re-assignment to another RLM task, and based thereon
sending, by the UE, a report to at least one access node indicating a number of antenna panels of the UE that are available for assignment to new RLM tasks.
2. The method of claim 1 , further comprising:
receiving, by the UE, an instruction to use at least one antenna panel for a new RLM task; and
operating, by the UE, the at least one antenna panel for the new RLM task in accordance with the received instruction.
3. The method of claim 2 , wherein the instruction is received from a first access node, and operating the at least one antenna panel for the new RLM task comprises measuring signals from a second access node.
4. The method of claim 1 , wherein the measurements of the received reference signals comprise at least one of channel measurements, interference measurements, or beam measurements.
5. The method of claim 1 , further comprising reporting, by the UE, at least one of the measurements of the received reference signals.
6. The method of claim 5 , wherein the at least one antenna panel is associated with the at least one of the measurements of the received reference signals.
7. The method of claim 5 , wherein the number of antenna panels of the UE that are available for assignment to new RLM tasks and the at least one of the measurements are reported in a message.
8. The method of claim 1 , further comprising receiving, by the UE, a request to report the number of antenna panels of the UE that are available for assignment to new RLM tasks.
9. The method of claim 1 , wherein the report indicating the number of antenna panels of the UE that are available for assignment to new RLM tasks is sent via a radio resource control (RRC) message.
10. The method of claim 1 , wherein the report indicating the number of antenna panels of the UE that are available for assignment to new RLM tasks is sent via a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH).
11. A computer-implemented method for operating a first access node, the method comprising:
transmitting, by the first access node, reference signals to a user equipment (UE);
receiving, by the first access node, a report from the UE indicating a number of antenna panels of the UE that are available for assignment to new radio link monitoring (RLM) tasks, the number of antenna panels of the UE that are available for assignment to new RLM tasks being determined based on measurements of the reference signals transmitted to the UE is currently-assigned to one RLM task to another RLM task; and
sending, by the first access node, an instruction to use at least one antenna panel for a new RLM task.
12. The method of claim 11 , further comprising sending, by the first access node, a request to report the number of antenna panels of the UE that are available for assignment to new RLM tasks.
13. The method of claim 12 , wherein the request is associated with a reporting of the measurements of the reference signals transmitted by the first access node.
14. The method of claim 13 , wherein the measurements of the reference signals transmitted by the first access node comprise at least one of channel measurements, interference measurements, or beam measurements.
15. The method of claim 13 , further comprising receiving, by the first access node from the UE, at least one of the measurements of the reference signals transmitted by the first access node.
16. The method of claim 15 , wherein the at least one antenna panel is associated with the at least one of the measurements of the reference signals transmitted by the first access node.
17. The method of claim 15 , wherein the number of antenna panels of the UE that are available for assignment to new RLM tasks and the at least one of the measurements are reported in a common message.
18. The method of claim 11 , wherein the report is received in a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH).
19. The method of claim 11 , wherein the report indicating the number of antenna panels of the UE that are available for assignment to new RLM tasks is received in an RRC message.
20. A user equipment (UE) comprising:
a non-transitory memory storage comprising instructions; and
one or more processors in communication with the memory storage, wherein the one or more processors execute the instructions to:
perform measurements of in accordance with received reference signals,
determine, in accordance with the measurements of the received reference signals, that at least one antenna panel, which is currently-assigned to one radio link monitoring (RLM) task, is available for re-assignment to another RLM task, and
send a report to at least one access node indicating a number of antenna panels of the UE that are available for assignment to new RLM tasks.
21. The UE of claim 20 , wherein the one or more processors further execute the instructions to receive an instruction to use the at least one antenna panel for a new RLM task, and operate the at least one antenna panel for the new RLM task in accordance with the received instruction.
22. The UE of claim 20 , wherein the one or more processors further execute the instructions to report at least one of the measurements of the received reference signals.
23. The UE of claim 20 , wherein the one or more processors further execute the instructions to receive a request to report the number of antenna panels of the UE that are available for assignment to new RLM tasks.
24. An access node comprising:
a non-transitory memory storage comprising instructions; and
one or more processors in communication with the memory storage, wherein the one or more processors execute the instructions to:
receive a report indicating a number of antenna panels of a user equipment (UE) that are available to new radio link monitoring (RLM) tasks, the UE determining in accordance with measurements of received reference signals by the UE, that at least one antenna panel, which is currently-assigned to one RLM task, is available for re-assignment to another RLM task; and
send an instruction on use of the at least one antenna panel.
25. The access node of claim 24 , wherein the one or more processors further execute the instructions to send a request to report the number of antenna panels of the UE that are available for assignment to new RLM tasks.
26. The access node of claim 25 , wherein the request is associated with a reporting of the measurements of the signals transmitted by the access node, and wherein the one or more processors further execute the instructions to receive a report of at least one of the measurements.
