Embodiment 1

[0055] refer to figure 1 , is the flow chart of the first embodiment of the multicast single frequency network transmission time configuration method of the present invention, mainly including the following steps:

[0056] Step 101, acquiring component carriers supporting MBSFN transmission in the system;

[0057] Step 102: Send a broadcast message on a component carrier capable of configuration among the component carriers supporting MBSFN transmission, where the broadcast message includes the MBSFN transmission time information of the component carrier.

[0058] Such as figure 2 As shown, for a carrier aggregation system supporting N available for MBSFN transmission, each component carrier configures its own MBSFN transmission time. The MBSFN transmission time of each component carrier may be the same or different.

[0059] It can be seen that by using the multicast single frequency network transmission time configuration method of the embodiment of the present invention...

Embodiment 2

[0061] The second embodiment of the method for configuring the transmission time of the multicast single frequency network of the present invention is the same as figure 1 The flow shown is similar, except that in this embodiment, the broadcast message also includes MBSFN transmission time information of other component carriers supporting MBSFN transmission; the other component carriers supporting MBSFN transmission include: A component carrier, and / or a component carrier that does not have a configuration capability.

[0062] Such as image 3 As shown, it is a schematic diagram of the MBSFN transmission time of each carrier in the second embodiment of the method of the present invention.

[0063] exist image 3 In , all component carriers can configure the MBSFN transmission time of themselves and other component carriers. At the first moment, CC 1 configures MBSFN transmission for CC 2 and itself. At the second moment, CC 2 configures MBSFN transmission for CC 1 and its...

Embodiment 3

[0069] refer to Figure 5 , is the flowchart of the third embodiment of the multicast single frequency network transmission time configuration method of the present invention, mainly including the following steps:

[0070] Step 501, acquiring component carriers in the system that support MBSFN transmission and have configuration capabilities;

[0071] Step 502: Send a broadcast message on the component carrier capable of configuration, where the broadcast message includes MBSFN transmission time information of other component carriers supporting MBSFN transmission.

[0072] Such as Figure 6 As shown, component carrier 1 and component carrier N can configure the MBSFN transmission time of other carriers. At the first and second moments, CC1 configures MBSFN transmission for CC2. At the third moment, CC1 configures MBSFN transmission for all CCs from CC2 to CCN.

[0073] It can be seen that by using the multicast single frequency network transmission time configuration meth...

Abstract

The invention discloses a multicast single-frequency network transmission time configuration method and a device. The method includes the following steps that: in a carrier aggregation system, member carriers supporting MBSFN transmission are acquired; and among the member carriers supporting MBSFN transmission, the member carriers with configuration capability send a broadcast message which contains the MBSFN transmission time information of the member carriers. The invention can ensure that a communication system adopting the carrier aggregation technique can support MBSFN transmission, so that the system frequency resource can be rationally utilized.

Description

technical field [0001] The invention relates to communication technology, in particular to a multicast single frequency network transmission time configuration method and equipment. Background technique [0002] The LTE (Long Term Evolution) system is a single-carrier system, that is, each cell in the system has only one carrier for transmission. In the LTE-A system, carrier aggregation technology is introduced in order to provide higher rate wireless transmission services. In a cell, multiple carriers of different frequencies can be used to serve a user at the same time, and each carrier is called a component carrier of the carrier aggregation system. [0003] MBSFN (Multicast Single Frequency Network) is a transmission method, that is, synchronous transmission in multiple cells at the same time and on the same frequency. Using this transmission mode can save frequency resources and improve spectrum utilization. It requires multiple cells to send exactly the same content...
