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

Abstract
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.

8. A method, in a UE (User Equipment) of radio communication networks, for receiving broadcast and multicast service from an eNB, comprising:
-
receiving from the eNB, in a MAC packet data unit, dynamic scheduling control information of the broadcast and multicast service for one scheduling period, the dynamic scheduling control information indicating the practical transmission of service data within the 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, and wherein padding is added only to the last subframe of each multicast channel in the scheduling period, and wherein the remaining subframes not being practically occupied by Multimedia Broadcast Multicast Service services transmission, discovered after the scheduling, are used for other services; and receiving the broadcast and multicast service data from the eNB in the scheduling period, according to the dynamic scheduling control information. - View Dependent Claims (9, 10, 11, 12, 13)

14. A device, in an eNB of radio communication networks, for providing a UE with broadcast and multicast service, comprising:
-
a determining unit, comprising at least a processor, configured to determine 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, wherein padding is added only to the last subframe of each multicast channel in the scheduling period; a first providing unit, comprising at least a processor, configured to provide, in a MAC packet data unit, the UE with the dynamic scheduling control information; and
a transmitter, for transmitting the broadcast and multicast service data to the UE in the scheduling period; andan allocating unit, comprising at least a processor, for reallocating subframes not being used for practical transmission to other services, according to the predefined ending subframe of the transmission of the service data in the scheduling period and the practical ending subframe of the transmission of the service data in the scheduling period.

15. A device, in a UE of radio communication networks, for receiving broadcast and multicast service from an eNB, comprising:
-
a first obtaining unit, comprising at least a processor, configured to receive from the eNB, in a MAC packet data unit, dynamic scheduling control information of the broadcast and multicast service for one scheduling period, the dynamic scheduling control information indicating the practical transmission of service data within the 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, wherein, during practical transmission and dynamic scheduling, padding is added only to the last subframe of each multicast channel in the scheduling period, and wherein the remaining subframes not being practically occupied by Multimedia Broadcast Multicast Service services transmission, discovered after the scheduling, are used for other services; a receiving unit, comprising at least a receiver, configured to receive the broadcast and multicast service data from the eNB in the scheduling period, according to the dynamic scheduling control information, wherein the receiving unit further comprises a processing unit, comprising at least a processor, for determining the starting subframe and the ending subframe of the transmission of the broadcast and multicast service in the scheduling period.
