Abstract

A notification regarding a transition of a User Equipment (UE) from a standby operating mode to an active operating mode is exchanged between a UE and a network element in a communication network. The notification could be an uplink notification that is transmitted by the UE to the network element in response to an operating mode transition criterion for the UE being met at the UE, or a downlink notification that is transmitted by the network element to the UE in response to an operating mode transition criterion for the UE being met at the network element. The UE transitions from the standby operating mode to the active operating mode in response to the operating mode transition criterion being satisfied. The transmitter of the notification, which could be the UE or the network element, could also perform grant-free transmission of data without first receiving a response to the notification.

Claims

1. A method performed by a user equipment (UE), the method comprising:

transmitting a notification to a network element in a communication network in response to an operating mode transition criterion for the UE being satisfied; and

transitioning the UE from a standby operating mode to an active operating mode in response to the operating mode transition criterion being satisfied.

2. The method of claim 1, further comprising:

performing grant-free transmission of data to the network element before a response to the notification is received.

3. The method of claim 2, wherein the operating mode transition criterion is associated with data that is to be transmitted by the UE, and wherein performing comprises performing grant-free transmission of all or part of the data to the network element before a response to the notification is received.

4. The method of claim 1, further comprising:

determining whether the operating mode transition criterion is satisfied.

5. The method of claim 1, wherein the operating mode transition criterion comprises an amount of data for transmission from the UE meeting or exceeding a threshold.

6. The method of claim 5, wherein the threshold is based on a parameter of grant-free uplink transmission.

7. The method of claim 5, wherein the threshold is based on an amount of data that can be transmitted from the UE in a single grant-free uplink transmission.

8. The method of claim 1, wherein the operating mode transition criterion comprises an amount of data expected to be received by the UE meeting or exceeding a threshold.

9. The method of claim 1, wherein the notification comprises a sequence that was previously transmitted by the UE using first communication resources, and wherein transmitting the notification comprises transmitting the sequence using second communication resources which are different from the first communication resources.

10. The method of claim 1, wherein the notification comprises a first sequence, and wherein transmitting the notification comprises transmitting the first sequence using communication resources that were previously used by the UE to transmit a second sequence that is different from the first sequence.

11. The method of claim 1, wherein the notification comprises a UE data buffer status report, and wherein transmitting the notification comprises transmitting the UE data buffer status report in a grant-free transmission to the network element.

12. The method of claim 1, wherein transmitting the notification comprises transmitting the notification to the network element in a grant-free transmission when the UE is in the standby operating mode.

13. The method of claim 2, wherein the data, communication resources that are used for the grant-free transmission, or both the data and the communication resources that are used for the grant-free transmission are associated with an identifier of the UE.

14. The method of claim 1, further comprising:

performing scheduled transmission of data to the network element after receiving a grant of communication resources from the network element.

15. The method of claim 1, further comprising:

transmitting Channel State Information (CSI) to the network element.

16. A non-transitory processor-readable medium storing instructions, when executed by one or more processors, cause the one or more processors to perform a method comprising:

transmitting a notification from a user equipment (UE) to a network element in a communication network in response to an operating mode transition criterion for the UE being satisfied; and

transitioning the UE from a standby operating mode to an active operating mode in response to the operating mode transition criterion being satisfied.

17. A User Equipment (UE) comprising:

a transmitter to transmit a notification to a network element in a communication network in response to an operating mode transition criterion for the UE being satisfied; and

a mode controller, coupled to the transmitter, to transition the UE from a standby operating mode to an active operating mode in response to the operating mode transition criterion being satisfied.

18. The UE of claim 17, wherein the transmitter is further configured to perform grant-free transmission of data to the network element before a response to the notification is received.

20. The UE of claim 17, wherein the mode controller is further configured to determine whether the operating mode transition criterion is satisfied.

21. The UE of claim 17, wherein the operating mode transition criterion comprises an amount of data for transmission from the UE meeting or exceeding a threshold.

24. The UE of claim 17, wherein the operating mode transition criterion comprises an amount of data expected to be received by the UE meeting or exceeding a threshold.

28. The UE of claim 17, wherein the transmitter is configured to transmit the notification in a grant-free transmission when the UE is in the standby operating mode.

30. The UE of claim 17, wherein the transmitter is further configured to perform scheduled transmission of data to the network element after receiving a grant of communication resources from the network element.

31. The UE of claim 17, further comprising:

a channel state monitor, coupled to the transmitter, to measure a communication channel state at the UE,

wherein the transmitter is further configured to transmit Channel State Information (CSI), in accordance with the measured communication channel state, to the network element.
