Abstract

A primary network node ("MN") is in a communication network that includes a secondary network node ("SN"). The MN and SN are configured to provide dual connectivity for the communication device. The MN sends 1110 a message to the SN. The message includes a request for the SN to modify operation of a secondary cell group ("SCG") controlled by the SN. The MN determines (1120) configuration information based on modifications to the operation of the SCG. The MN sends (1130) an indication of the configuration information to the communication device.

Description

Processing of quality of experience configuration upon secondary cell group deactivation Technical Field The present disclosure relates to wireless communication systems, and more particularly, to handling quality of experience ("QoE") configuration upon secondary cell group ("SCG") deactivation. Background Fig. 1 shows an example of a new radio ("NR") network (e.g., a fifth generation ("5G") network) including a 5G core ("5 GC") network 130, network nodes 120 a-120 b (e.g., 5G base stations ("gnbs")), a plurality of communication devices 110 (also referred to as user equipment ("UEs")). Disclosure of Invention According to some embodiments, a method of operating a primary network node ("MN") in a communication network including a secondary network node ("SN") is provided. The MN and SN are configured to provide dual connectivity for the communication device. The method includes sending a message to the SN, the message including a request for the SN to modify operation of a secondary cell group ("SCG") controlled by the SN. The method further includes determining configuration information based on a modification of the operation of the SCG. The method also includes sending an indication of the configuration information to the communication device. According to other embodiments, a method of operating a secondary network node ("SN") in a communication network including a primary network node ("MN") is provided. The MN and SN are configured to provide dual connectivity for the communication device. The method includes receiving a message from the MN, the message including a request for the SN to modify operation of a secondary cell group ("SCG") controlled by the SN. The method further includes determining configuration information based on a modification of operation of the SCG in response to receiving the message. The method further includes modifying operation of the SCG in response to receiving the message. The method further includes sending an indication of the configuration information to the MN. According to other embodiments, a method of operating a communication device in a communication network comprising a primary network node ("MN") and a secondary network node ("SN"), the MN and SN providing dual connectivity for the communication device, is provided. The method includes receiving a message from the MN, the message including an indication of a modification of operation of a secondary cell group ("SCG") controlled by the SN and an indication of configuration information associated with reporting to the SN. The method also includes sending a report based on the configuration information. According to other embodiments, a MN, SN, communications device, computer program product, non-transitory computer readable medium, host, or system is provided to perform the above methods. Certain aspects of the present disclosure and embodiments thereof may provide technical advantages. An advantage of some embodiments is that it allows for reconfiguration of QoE configuration in a UE as part of an SCG deactivation procedure. In some embodiments, reconfiguration of QoE configuration may be performed without additional delay of SCG deactivation process. In some examples, this is beneficial to the UE because energy consumption in the UE is reduced when the SCG is deactivated. In additional or alternative examples, it may be desirable to reconfigure the UE upon SCG deactivation so as not to lose any SN-related QoE reports upon SCG deactivation for the UE.
