Embodiment Construction

[0049] According to the MBMS data carried by the logical channel in the scheduling period, the embodiment of the present invention generates MBMS indication information, and places the MBMS indication information in the MAC CE (downlink media access control protocol control unit) of the MAC PDU (downlink media access control protocol data unit). ) and / or the MAC subheader corresponding to the MAC CE, and send the MAC PDU to the user terminal; the user terminal determines the MBMS data carried by the logical channel in the scheduling period according to the MBMS indication information. Since the MBMS data carried by the logic channel in the scheduling period of the user terminal can be indicated, the receiving difficulty of the user terminal is reduced.

[0050] The embodiment of the present invention generates MBMS notification information according to the service state of the MBMS data corresponding service carried by the logical channel in the scheduling period, and places th...

Abstract

The embodiment of the invention relates to wireless communication technology and in particular relates to a method, a system and a device for determining multimedia broadcast multicast service (MBMS) information to solve the problem that user equipment (UE) does not know where the MBMS data to be received appears in the receiving process so as to prolong the monitoring time of the UE. The method comprises the following steps of: generating MBMS indication information according to a logic channel for bearing the MBMS data in a scheduling period; putting the MBMS indication information into MACCE (media access control layer control element) of MAC PDU (media access control protocol data unit) and / or an MAC subhead corresponding to the MAC CE; and sending the MAC PDU to a user terminal to indicate the user terminal to determine the MBMS data borne by the logic channel in the scheduling channel according to the MBMS indication information. The method can indicate the MBMS data borne by the logic channel in the scheduling period of the user terminal so as to reduce the receiving difficulty of the user terminal.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method, system and device for determining MBMS information. Background technique [0002] MBMS (Multimedia Broadcast Multicast Service, Multimedia Broadcast Multicast Service) is used to provide multimedia broadcast services and multimedia multicast services for user terminals in wireless cells. [0003] MBMS can perform single-cell transmission or multi-cell transmission. [0004] MBMS single-cell transmission means that MBMS is only transmitted within the coverage of a designated cell, and does not support the combination of MBMS transmissions from other cells; MBMS multi-cell transmission adopts MBSFN (Multicast Broadcast Single Frequency Network, multicast single frequency network) ) transmission mode, that is, a transmission mode in which exactly the same content is transmitted simultaneously in multiple cells with the same frequency at the same time, and the U...
