Abstract

A Method and Apparatus for application layer measurement reporting upon synchronous reconfiguration is provided. The method includes transmitting to the base station a terminal capability information message about the application layer measurement and conditional handover and the reception of segmented downlink RRC message, receiving from the base station a first RRC reconfiguration message containing a other configuration and first information for SRB4, receiving a second RRC reconfiguration message containing a third RRC reconfiguration message from said base station, discarding the segments of the segmented RRC messages stored in the RRC when said third RRC reconfiguration message is applied due to the conditional reconfiguration execution, and discarding the segmented RRC messages stored in the PDCP when PDCP reestablishment is set in the second information for SRB4.

Claims (49)

1. A method performed by a user device, the method comprising:

receiving, from a base station, a radio resource control (RRC) setup message comprising a first configuration parameter for signaling radio bearer (SRB), wherein the first configuration parameter for SRB is for configuring signaling radio bearer 1 (SRB1);

receiving at least one RRC configuration comprising a second configuration parameter for SRB, wherein the second configuration parameter for SRB is for configuring signaling radio bearer 4 (SRB4);

receiving, from the base station via a first cell, first configuration information comprising:

a parameter that indicates RRC segmentation is enabled; and

at least one configuration of application layer measurements;

generating an RRC message comprising an application layer measurement report associated with the at least one configuration of application layer measurements;

generating, based on the generated RRC message being larger than a specific size and based on the parameter that indicates RRC segmentation is enabled, at least one uplink message segment by segmenting the generated RRC message;

transmitting, to the base station, the at least one uplink message segment via SRB4;

receiving, from the base station, a second RRC message comprising second configuration information, wherein the second configuration information comprises information for a second cell;

transmitting, to the base station via the second cell, a third RRC message in response to the second RRC message; and

performing, via the second cell, retransmission of the at least one uplink message segment via SRB4.

2. The method of claim 1 , wherein the first configuration parameter for SRB comprises a first SRB-ToAddMod information element (IE), and

wherein the second configuration parameter for SRB comprises a second SRB-ToAddMod IE.

3. The method of claim 1 , wherein the at least one RRC configuration comprising the second configuration parameter for SRB comprises an RRC reconfiguration message comprising the second configuration parameter for SRB.

4. The method of claim 1 , wherein the second RRC message comprising the second configuration information comprises an RRC reconfiguration message comprising the second configuration information.

5. The method of claim 1 , further comprising:

based on the first configuration parameter for SRB, establishing SRB1.

6. The method of claim 1 , further comprising:

based on the second configuration parameter for SRB, establishing SRB4.

7. The method of claim 1 , wherein the parameter that indicates RRC segmentation is enabled comprises an rrc-SegAllowed parameter that indicates that RRC segmentation associated with the application layer measurement report is enabled.

8. The method of claim 1 , wherein the at least one configuration of application layer measurements comprises at least one measConfigAppLayer parameter.

9. The method of claim 8 , wherein the generating the RRC message comprises:

generating, based on at least one application layer measurement report associated with the at least one measConfigAppLayer parameter being available, the RRC message.

10. A method performed by a user device, the method comprising:

receiving, from a base station, a radio resource control (RRC) setup message comprising a first configuration parameter for signaling radio bearer (SRB), wherein the first configuration parameter for SRB is for configuring signaling radio bearer 1 (SRB1);

receiving at least one RRC configuration comprising:

a second configuration parameter for SRB, wherein the second configuration parameter for SRB is for configuring signaling radio bearer 4 (SRB4); and

first configuration information comprising:

a parameter that indicates RRC segmentation is enabled; and

at least one configuration of application layer measurements;

generating an RRC message comprising an application layer measurement report associated with the at least one configuration of application layer measurements;

generating, based on the generated RRC message being larger than a specific size and based on the parameter that indicates RRC segmentation is enabled, at least one uplink message segment by segmenting the generated RRC message;

transmitting the at least one uplink message segment via SRB4;

receiving, from the base station, a second RRC message comprising second configuration information, wherein the second configuration information comprises reconfiguration information for a cell;

transmitting, to the base station, a third RRC message in response to the second RRC message; and

performing, based on the reconfiguration information for the cell, retransmission of the at least one uplink message segment via SRB4.

11. The method of claim 10 , wherein the first configuration parameter for SRB comprises a first SRB-ToAddMod information element (IE), and

wherein the second configuration parameter for SRB comprises a second SRB-ToAddMod IE.

12. The method of claim 10 , wherein the at least one RRC configuration comprising the second configuration parameter for SRB comprises an RRC reconfiguration message comprising the second configuration parameter for SRB.

13. The method of claim 10 , wherein the second RRC message comprising the second configuration information comprises an RRC reconfiguration message comprising the second configuration information.

14. The method of claim 10 , further comprising:

based on the first configuration parameter for SRB, establishing SRB1.

15. The method of claim 10 , further comprising:

based on the second configuration parameter for SRB, establishing SRB4.

16. The method of claim 10 , wherein the parameter that indicates RRC segmentation is enabled comprises an rrc-SegAllowed parameter that indicates that RRC segmentation associated with the application layer measurement report is enabled.

17. The method of claim 10 , wherein the at least one configuration of application layer measurements comprises at least one measConfigAppLayer parameter.

18. The method of claim 17 , wherein the generating the RRC message comprises:

generating, based on at least one application layer measurement report associated with the at least one measConfigAppLayer parameter being available, the RRC message.
