Problems solved by technology

[0012] Considering that there will be receivers of R10, R9, and R8 in LTE-Advanced in the future, and new high-efficiency pilots are adopted in the LTE-Advanced system, and the receivers of R8 and R9 cannot recognize these new pilots. The receivers of R8, R9, and R10 are scheduled at the same time in a subframe, and the subframe has to use the old pilot, but this will lead to a decrease in system efficiency. Therefore, it is best to schedule the receiver of R10 in a subframe. The high-efficiency pilot designed for the R10 receiver can be used, and the receivers of R8 and R9 do not receive PDSCH on these subframes configured for the R10 receiver, and skip these subframes directly
According to the existing protocol, the R8 receiver directly skips the PDSCH of all MBSFN subframes. The R9 protocol is being formulated. Up to now, the R9 receiver does not receive PDSCH on the MBSFN subframe, so the MBSFN subframe can be used for R10 reception. However, since the configured MBSFN subframes have many uses, it is not known which MBSFN subframes can be used to transmit unicast services for the R10 receiving end

Embodiment 1

[0070] In this embodiment, the subframe identification information of the MBSFN subframe that the PDCCH bears the PDSCH for the R10 receiver to transmit the PDSCH is an example to illustrate the specific process of transmitting the subframe identification information. The process is as shown in Figure 2 (a), including the following steps:

[0071] Step 200: The system is configured to transmit MBSFN subframes of PDSCH for the R10 receiving end, and form subframe identification information in these subframes;

[0072] In this step, the sender configures one or more of the MBSFN subframes configured in the MBSFN-SubframeConfigList in SIB2 as the MBSFN subframes for the R10 receiver to transmit PDSCH, or the sender can use the MBSFN-Subframe in SIB2 to improve system efficiency. SubframeConfigList configures too many MBSFN subframes, and further indicates the too many MBSFN subframes as MBSFN subframes for the R10 receiving end to transmit PDSCH. Of course, it can also include one o...

Embodiment 2

[0084] In this embodiment, the subframe identification information of the MBSFN subframe carrying the PDSCH carried by the BCCH for the R10 receiving end is taken as an example to illustrate the specific process of transmitting the subframe identification information. The process is as follows: image 3 (a), including the following steps:

[0085] Step 300: The system is configured to transmit the MBSFN subframe of the PDSCH for the R10 receiving end to form subframe identification information;

[0086] In this step, the sender configures one or more of the MBSFN subframes configured in the MBSFN-SubframeConfigList in SIB2 as the MBSFN subframes for the R10 receiver to transmit PDSCH, or the sender can use the MBSFN-Subframe in SIB2 to improve system efficiency. SubframeConfigList configures too many MBSFN subframes, and further indicates the too many MBSFN subframes as MBSFN subframes for the R10 receiving end to transmit PDSCH. Of course, it can also include one or more subfr...

Embodiment 3

[0097] In this embodiment, the specific process of transmitting the subframe identification information is described by taking the subframe identification information of the MBSFN subframe that the R10 receiver transmits the PDSCH through dedicated signaling as an example. The process is as follows: Figure 6 shown, including the following steps:

[0098] Step 600: The system is configured to transmit the MBSFN subframe of the PDSCH for the R10 receiving end to form subframe identification information;

[0099] In this step, the sender configures one or more of the MBSFN subframes configured in the MBSFN-SubframeConfigList in SIB2 as the MBSFN subframes for the R10 receiver to transmit PDSCH, or the sender can use the MBSFN-Subframe in SIB2 to improve system efficiency. SubframeConfigList configures too many MBSFN subframes, and further indicates the too many MBSFN subframes as MBSFN subframes for the R10 receiving end to transmit PDSCH. Of course, it can also include one or m...

Abstract

The invention relates to a transmission method and a system for subframe identification information, belonging to the field of communication. The method comprises the following steps: a transmitting end transmits the subframe identification information to an R10 receiving end in a physical downlink control channel (PDCCH) configured for transmitting a multicast broadcast single-frequency network (MBSFN) subframe of a physical downlink shared channel (PDSCH) for the R10 receiving end, wherein the subframe identification information is used for indicating that the MBSFN subframe is a multicast MBSFN subframe for transmitting PDSCH of the R10 receiving end. With a technical scheme of the invention, aim of an indication subframe can be effectively implemented, rapidity of indication information can be satisfied, and by adopting the method, the system is suitable for transmitting the indication information without increasing complexity of the receiving end.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a method and system for transmitting subframe identification information. Background technique [0002] With the rapid development of the Internet and the popularization of large-screen multifunctional mobile phones, a large number of mobile data multimedia services and various high-bandwidth multimedia services have emerged, such as video conferences, TV broadcasts, video on demand, advertisements, online education, interactive games, etc. On the one hand, it satisfies the ever-increasing business demands of mobile users, and at the same time brings new business growth points for mobile operators. These mobile data multimedia services require multiple users to receive the same data at the same time. Compared with general data services, they have the characteristics of large data volume, long duration, and delay sensitivity. [0003] In order to effectively utilize mobil...
