Abstract

A radio access network node delivering traffic flows to a plurality of idle user equipments via a multicast broadcast service may determine one of the user equipments as a primary user equipment and the other user equipment as a secondary user equipment. The primary user device may request quality of experience information or an indication from the secondary user device. The secondary user device may respond to the request for quality of experience information with an indication of quality of experience metric availability or actual quality of experience metric information. The availability indication may be used to reduce the size of the response to the request and may also be used to reduce the size of the quality of experience report generated by the primary user equipment and transmitted thereby to the node. The quality of experience report may be transmitted by the primary user equipment to the node such that an idle secondary user equipment does not need to connect to the node to transmit quality of experience information.

Description

Selective reporting of quality of experience for multicast and broadcast services RELATED APPLICATIONS The present application claims priority from U.S. non-provisional patent application Ser. No.18/451,374 entitled "SELECTIVE REPORTING OF QUALITY OF EXPERIENCE OF MULTOCAST AND BROADCAST TRAFFIC," filed 8/17 on 2023, the entirety of which is hereby incorporated by reference. Background The term "New Radio, NR" associated with the fifth generation mobile wireless Communication system ("5G") refers to a technical aspect for use in a Radio access network (Radio Access Network, "RAN") that includes several Quality-of-service classes (Quality-of-SERVICE CLASS, QOS), including ultra-high reliability low-latency communications (Ultra Reliable and Low Latency Communications, "URLLC"), enhanced mobile broadband (Enhanced Mobile Broadband, "eMBB"), and mass machine type communications (MASSIVE MACHINE TYPE communications, "mMTC"). The URLLC QoS category is associated with stringent latency requirements (e.g., low latency or low signal/message latency) and high reliability of radio performance, while conventional eMBB use cases may be associated with high capacity wireless communications, which may allow for less stringent latency requirements (e.g., higher latency than URLLC) and lower reliability radio performance than URLLC. mMTC may have lower performance requirements than eMBB use case. Some use case applications involving mobile devices or mobile user devices (such as smartphones, wireless tablets, smartwatches, and the like) may impose different loads or demands on a given RAN resource.
