Selective reporting of quality of experience of multicast and broadcast traffic

Abstract

A radio access network node delivering a traffic flow via multicast broadcast service to multiple idle user equipment may determine one of the user equipment as a primary user equipment and the other user equipment as secondary user equipment. A primary user equipment may request quality-of-experience information, or indications, from secondary user equipment. The secondary user equipment may respond to a request for quality-of-experience information with a quality-of-experience metric availability indication or with actual quality-of-experience metric information. An availability indication may be used to reduce the size of a response to the request and also to reduce the size of a 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 so that the idle secondary user equipment need not connect to the node to transmit quality-of-experience information.
