Multicast channel control information

摘要

The present disclosure relates to a technique for configuring transmission of a multicast channel carrying scheduling information and data belonging to one or more multicast services, the scheduling information indicating scheduling of the multicast services mapped to the multicast channel. A method embodiment comprises the steps of configuring (404) the transmission of the scheduling information on the multicast channel based on a scheduling information specific transmission requirement and configuring (404) the transmission of the data belonging to the one or more multicast services based on a service specific transmission requirement; and signalling (406) the scheduling information specific transmission requirement and the service specific transmission requirement.

1. A method for configuring transmission of a multicast channel carrying scheduling information and data associated with a multicast service, the scheduling information indicating scheduling of the multicast service mapped to the multicast channel, and the method comprising:
determining a scheduling information specific Quality of Service (QoS) value related to a scheduling information specific QoS property; determining a service specific QoS value related to a service specific QoS property; configuring the transmission of the scheduling information associated with the multicast service on the multicast channel based on a scheduling information specific transmission requirement by:
if the scheduling information specific QoS value differs from the service specific QoS value, selecting the scheduling information specific transmission requirement based on the scheduling information specific QoS value and selecting a service specific transmission requirement based on the service specific QoS value, andif the scheduling information specific QoS value is equal to the service specific QoS value, selecting a same transmission requirement for the scheduling information specific transmission requirement and the service specific transmission requirement; configuring transmission of the data associated with the multicast service based on the service specific transmission requirement; and signaling the scheduling information specific transmission requirement and the service specific transmission requirement on the multicast channel.
