Radio beam management reporting operation with connected mode discontinuous reception
Systems, methods, apparatuses, and computer program products for beam management reporting in connected mode discontinuous reception (C-DRX) are provided. One method may include configuring, by a network node, a user equipment with a timer that may be started when user equipment active time starts. The method may also include, while the configured timer is running, preventing the user equipment from generating a beam management report autonomously.
1. A method, comprising:
configuring, by a network node, a user equipment with a timer that is started when user equipment active time starts; and
sending the configuration for the timer to the user equipment, wherein when the configured timer is running, it prevents the user equipment from generating a beam management report autonomously.
2. The method according to claim 1 , further comprising:
providing the user equipment with a valid uplink grant, which allows the user equipment to generate the beam management report; and
receiving the beam management report from the user equipment in uplink after the configured timer expires.
3. The method according to claim 2 , wherein the receiving comprises receiving, by the network node, the beam management report piggybacked with other data in a medium access control (MAC) control element (CE).
4. The method according to claim 2 , wherein the receiving comprises:
receiving the beam management report on a physical uplink shared channel (PUSCH) allocation that was provided for other purposes; or
receiving the beam management report on a physical uplink control channel (PUCCH) allocation.
5. The method according to claim 2 , wherein the receiving comprises, when the configured timer expires and the user equipment is still on active time monitoring physical downlink control channel (PDCCH), receiving at least one of the beam management report or scheduling request (SR) from the user equipment.
6. The method according to claim 1 , wherein the configuring comprises configuring the user equipment to be prevented from generating or sending a beam management report unless a ‘drx-InactivityTimer’ is running.
7. The method according to claim 1 , wherein the configuring comprises configuring the user equipment to be prevented from generating or sending a beam management report when an ‘onDurationTimer’ is running.
8. The method according to claim 1 , further comprising configuring the beam management report to be of limited form or size during the configured timer so that a limited number of beams are reported.
9. The method according to claim 1 , further comprising providing the user equipment with a medium access control or physical downlink control channel order to reset the configured timer to prolong the time the user equipment is prohibited to send a report or to skip the configured timer and be allowed to generate the beam management report.
10. The method according to claim 1 , further comprising using uplink grant of sufficient size to poll the user equipment to provide the beam management report.
11. An apparatus, comprising:
at least one processor; and
at least one memory comprising computer program code,
the at least one memory and computer program code configured, with the at least one processor, to cause the apparatus at least to
configure a user equipment with a timer that is started when user equipment active time starts; and
send the configuration for the timer to the user equipment, wherein when the configured timer is running, it prevents the user equipment from generating a beam management report autonomously.
12. The apparatus according to claim 11 , wherein the at least one memory and computer program code are further configured, with the at least one processor, to cause the apparatus at least to:
provide the user equipment with a valid uplink grant, which allows the user equipment to generate the beam management report; and
receive the beam management report from the user equipment in uplink after the configured timer expires.
13. The apparatus according to claim 12 , wherein when receiving, the at least one memory and computer program code are configured, with the at least one processor, to cause the apparatus at least to receive the beam management report piggybacked with other data in a medium access control (MAC) control element (CE).
14. The apparatus according to claim 12 , wherein when receiving, the at least one memory and computer program code are configured, with the at least one processor, to cause the apparatus at least to:
receive the beam management report on a physical uplink shared channel (PUSCH) allocation that was provided for other purposes; or
receive the beam management report on a physical uplink control channel (PUCCH) allocation.
15. The apparatus according to claim 12 , wherein when receiving, the at least one memory and computer program code are configured, with the at least one processor, to cause the apparatus at least to receive, when the configured timer expires and the user equipment is still on active time monitoring physical downlink control channel (PDCCH), at least one of the beam management report or scheduling request (SR) from the user equipment.
16. The apparatus according to claim 11 , wherein when configuring, the at least one memory and computer program code are configured, with the at least one processor, to cause the apparatus at least to configure the user equipment to be prevented from generating or sending a beam management report unless a ‘drx-InactivityTimer’ is running.
17. The apparatus according to claim 11 , wherein when configuring, the at least one memory and computer program code are configured, with the at least one processor, to cause the apparatus at least to configure the user equipment to be prevented from generating or sending a beam management report when an ‘onDurationTimer’ is running.
18. The apparatus according to claim 11 , wherein when configuring, the at least one memory and computer program code are configured, with the at least one processor, to cause the apparatus at least to configure the beam management report to be of limited form or size during the configured timer so that a limited number of beams are reported.
19. The apparatus according to claim 11 , wherein the at least one memory and computer program code are further configured, with the at least one processor, to cause the apparatus at least to provide the user equipment with a medium access control or physical downlink control channel order to reset the configured timer to prolong the time the user equipment is prohibited to send a report or to skip the configured timer and be allowed to generate the beam management report.
20. The apparatus according to claim 11 , wherein the at least one memory and computer program code are further configured, with the at least one processor, to cause the apparatus at least to use uplink grant of sufficient size to poll the user equipment to provide the beam management report.
21. An apparatus, comprising:
at least one processor; and
at least one memory comprising computer program code,
the at least one memory and computer program code configured, with the at least one processor, to cause the apparatus at least to
receive a configuration for a timer that is started when a user equipment active time according to a discontinuous reception cycle starts; and
while the timer is running, prevent the apparatus from generating a beam management report autonomously.
22. The apparatus according to claim 21 , wherein the at least one memory and computer program code are further configured, with the at least one processor, to cause the apparatus at least to:
receive a valid uplink grant from a network; and
