Problems solved by technology

Since the UE that does not receive the MBSFN service on the corresponding MCH will not monitor the information of the MBSFN subframes of the corresponding MCH (or PMCH), the network side and the user terminal cannot use these subframes to transmit other non-MBMS data, resulting in the information on these subframes resources are wasted
[0009] To sum up, at present, for MBSFN subframes that do not actually carry MBMS, since the UE does not monitor the information of these subframes, the network side and the user terminal cannot use these subframes to transmit data, resulting in a waste of resources for these subframes

Embodiment Construction

[0034] In the embodiment of the present invention, the network side sends configuration information to the user terminal when there is an idle MBSFN subframe; the user terminal monitors the idle MBSFN subframe determined according to the configuration information; the network side and the user terminal transmit non-MBMS data through the idle MBSFN subframe. Since the user terminal can be instructed to monitor the MBSFN subframes that do not actually carry MBMS data, non-MBMS data can be sent between the network side and the user terminal through these subframes, avoiding wasting unlimited resources on these subframes.

[0035] Wherein, the idle MBSFN subframe in the embodiment of the present invention may be on the MCH or on the PMCH. Of course, other channels capable of carrying MBSFN subframes are also applicable to this embodiment of the present invention.

[0036] Among them, after the user terminal receives the MBSFN subframe allocation method sent by the network side, if...

Abstract

The embodiment of the invention relates to wireless communication technology, in particular to a method, a system and a device for transmitting data, which are used for solving the problem that resource waste is caused because a network side and a user terminal cannot transmit the data by using a multimedia broadcast single frequency network (MBSFN) sub-frame which does not actually bear multimedia broadcast multicast service (MBMS) in the prior art. The method of the embodiment of the invention comprises the following steps that: the network side generates configuration information which can make the user terminal to determine an idle MBSFN sub-frame when the idle MBSFN sub-frame exists in a multicast channel (MCH), wherein the idle MBSFN sub-frame is the MBSFN sub-frame which does not actually bear the MBMS data during transmission of the MBMS service; the network side transmits the configuration information to the user terminal for indicating the user terminal to monitor the idle MBSFN sub-frame determined according to the configuration information; and the network side and the user terminal transmit non-MBMS data through the idle MBSFN sub-frame.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method, system and device for transmitting data. 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 UE (user ter...
