Communication method and device of broadcast and/or multicast in radio network

摘要

The invention discloses a communication method and device of broadcast and/or multicast in radio network. The eNB determines dynamic scheduling control information of each service, according to the practical transmission of the broadcast and/or multicast service in one scheduling period, and provides, in a MAC packet data unit, the UE with the dynamic scheduling control information; the UE receives, in a MAC packet data unit, the dynamic scheduling control information, and receives the broadcast and/or multicast service data from the eNB in the scheduling period, according to the dynamic scheduling control information.

主权项

1. A method, in an eNB of radio communication networks, for providing a UE (User Equipment) with broadcast and multicast service, comprising:
determining dynamic scheduling control information of each service, according to the practical transmission of the broadcast and multicast service in one scheduling period,
wherein the dynamic scheduling control information comprises at least information about the practical ending subframe of the transmission of the service data in the scheduling period, wherein the information about the practical ending subframe of the transmission comprises the serial number of the practical ending subframe of the transmission in multicast subframes of the scheduling period, andwherein padding is added only to the last subframe of each multicast channel in the scheduling period, andwherein the remaining subframes not being practically occupied by Multimedia Broadcast Multicast Service services transmission, discovered after the scheduling, are used for other services; providing, in a MAC packet data unit, the UE with the dynamic scheduling control information; and transmitting the broadcast and multicast service data to the UE in the scheduling period.
