For example, it may be a portable, pocket, handheld, computer built-in or in-vehicle mobile device that exchanges language and/or data with a wireless access network. For example, Personal Communication Service (PCS) telephone, cordless telephone, Session Initiation Protocol (SIP) telephone, Wireless Local Loop (WLL) station, personal digital assistant (Personal) Digital Assistant, PDA for short.

1 is a schematic diagram of an application scenario of a subframe configuration method provided by the present invention. The application scenario may be an LTE system, but is not limited thereto. As shown in FIG. 1 , the scenario may include: an MCE, a base station, and a terminal.

The Multi-cell/Multicast Coordination Entity (MCE) is a core network side network element.

The MCE is configured to configure the MBSFN area, including the allocation of the MBSFN subframe for the radio frame, and the MCE is further configured to send the related information of the subframe configuration to the base station, so that the base station can learn the MBSFN subframe according to the related information of the subframe configuration. The MBSFN area and further indicates the terminal.

Currently, a radio frame includes multiple subframes, where the subframe is used as a basic scheduling time unit. Generally, one radio frame may include 10 subframes, and frequency division duplex (FDD) mode, 10 sub-frames. There may be a maximum of 6 MBSFN subframes in a frame. In time division duplex (TDD) mode, there may be up to 5 MBSFN subframes in 10 subframes.

In order to enhance the performance of the MBMS, it is considered that the number of MBSFN subframes in the radio frame can be increased. Specifically, since the paging subframe exists on the primary carrier, and the MBSFN subframe uses the entire system bandwidth for transmitting the MBMS service, the primary The paging subframe on the carrier cannot be configured as MBSFN The subframes are generally used to increase the number of MBSFN subframes on the secondary carrier. The number of the MBSFN subframes is not limited. In addition, the non-MBSFN area in the MBSFN subframe may be cancelled. That is, one MBSFN subframe is used to transmit the MBMS service.

The embodiment of the present invention mainly implements the structure of notifying the terminal of the MBSFN subframe, so that the terminal knows the specific regional distribution inside the MBSFN subframe.

2 is a schematic flowchart of Embodiment 1 of a method for configuring a subframe according to the present invention. As shown in FIG. 1, the method includes:

S201. The base station sends an MBSFN subframe indication information to the terminal, where the MBSFN subframe indication information is used to indicate whether all areas in the MBSFN subframe are MBSFN areas.

In a specific implementation, before the S201, the multi-cell/multicast coordination entity (MCE) specifically configures the structure of each subframe, including determining which subframes in the radio frame are MBSFN subframes, and determining the MBSFN. The MBSFN area in the subframe, and the like, further generate subframe configuration information, so as to indicate the structure of each subframe in the radio frame. Optionally, the MBSFN subframe indication information may also indicate whether all regions in the MBSFN subframe of the base station are MBSFN area.

Specifically, the base station may receive the MBSFN subframe indication information sent by the MCE, and indicate whether all the regions in the MBSFN subframe of the base station are MBSFN regions by using the MBSFN subframe indication information.

Further, if the MBSFN subframe includes both the non-MBSFN area and the MBSFN area, the MCE may also indicate information such as the number of symbols of the non-MBSFN area and/or the number of symbols of the MBSFN area, and specifically may only indicate the number of symbols of the non-MBSFN area, and the like. There are no restrictions here. The symbol in the embodiment of the present invention may be an Orthogonal Frequency Division Multiplexing (OFDM) symbol.

Optionally, after receiving the MBSFN subframe indication information sent by the MCE, the base station may parse the MBSFN subframe indication information, and repackage the MBSFN subframe indication information to indicate whether all the regions in the MBSFN subframe are MBSFN regions. Then, the base station sends the MBSFN subframe indication information generated by itself to the terminal.

S202. The terminal receives the MBSFN subframe indication information sent by the base station.

S203. The terminal determines, according to the MBSFN subframe indication information, whether all areas in the MBSFN subframe are MBSFN areas.

That is, there may be no non-MBSFN area in the future MBSFN subframe, but the terminal does not know, and the base station needs to perform an indication, and the terminal determines, according to the MBSFN subframe indication information, whether all areas in the MBSFN subframe are MBSFN areas, and if so, it indicates There is no non-MBSFN area in the MBSFN subframe, otherwise it indicates that the MBSFN subframe includes both the MBSFN area and the non-MBSFN area.

After determining whether all the areas in the MBSFN subframe are MBSFN areas, the terminal may perform operations such as signal reception and RRM measurement according to the actual structure of the MBSFN subframe.

It should be noted that, in a unicast subframe, there is a CRS in the entire subframe, that is, a CRS exists in both the control region and the unicast data transmission region; and in the MBSFN subframe, the CRS is only performed in the non-MBSFN region. transmission. When performing radio resource management (RRM) measurement, the terminal mainly measures the CRS to obtain reference signal received power (RSRP) and reference signal received quality (reference signal received quality). Information such as RSRQ), RRM measurement will be performed at the corresponding CRS position during specific measurement.

If the terminal does not know that all the areas in the MBSFN sub-frame are MBSFN areas, that is, there is no non-MBSFN area, RRM measurement may be performed in the MBSFN area, resulting in erroneous measurement and affecting the accuracy of the measurement result.

The terminal determines whether all the regions in the MBSFN subframe are MBSFN regions according to the MBSFN subframe indication information, and then performs RRM measurement, which greatly improves the measurement accuracy.

If the terminal determines that all areas in the MBSFN subframe are MBSFN areas, RRM measurement is not performed based on this MBSFN subframe.

It should be noted that the foregoing terminal may be a terminal that supports carrier aggregation (CA), and the terminal receives the MBSFN subframe indication information sent by the base station, and the terminal may know the area where the CRS exists, so that the terminal uses the CRS. RRM measurement.

The MBSFN subframe in the embodiment of the present invention generally belongs to the secondary carrier, and may be configured according to the MBSFN subframe indication information, but is not limited thereto.

In this embodiment, the terminal receives the MBSFN subframe indication information sent by the base station, where the MBSFN subframe indication information is used to indicate whether all the regions in the MBSFN subframe are MBSFN regions, and the terminal may determine the MBSFN subframe according to the MBSFN subframe indication information. Whether all the areas are MBSFN areas, that is, the terminal can know the MBSFN area inside the subframe. In addition, it can help to ensure the accuracy of subsequent signal reception and RRM measurement.

Optionally, the foregoing base station sends the MBSFN subframe indication information to the terminal, which may be a unicast mode or a broadcast mode.

Optionally, the foregoing MBSFN subframe indication information may be carried on at least one indication bit in a system message broadcast by the base station. Specifically, the system message may be a system message for indicating a secondary carrier configuration, and the terminal performs secondary carrier configuration according to the received system message.

Alternatively, the foregoing MBSFN subframe indication information may be carried on at least one indication bit in the dedicated signaling sent by the base station to the terminal. The dedicated signaling may be dedicated signaling for indicating a secondary carrier configuration, and the terminal performs secondary carrier configuration according to the received dedicated signaling.

That is, one or more indicator bits may be extended in a system message or dedicated signaling sent by the base station to the terminal, and the indication bit is used to identify the MBSFN subframe indication information.

It should be noted that the system message may be a system information block (SIB), for example, may be SIB2, and is not limited herein; the dedicated signaling may be a radio resource control (RRC). Dedicated RRC signaling, which is not limited here.

FIG. 3 is a schematic flowchart diagram of Embodiment 2 of a subframe configuration method according to the present invention.

The MBSFN subframe indication information may be a carrier type identifier. That is, the terminal distinguishes whether all the areas in the MBSFN subframe are MBSFN areas according to the carrier type.

Correspondingly, as shown in FIG. 3, the terminal determines, according to the MBSFN subframe indication information, whether all the regions in the MBSFN subframe are MBSFN regions, and may include:

S301. The terminal determines, according to the carrier type identifier, a carrier type of a carrier to which the MBSFN subframe belongs.

S302. The terminal determines, according to the carrier type of the carrier to which the MBSFN subframe belongs, whether all regions in the MBSFN subframe are MBSFN regions.

MBSFN subframes on certain types of carriers may not contain non-MBSFN areas, and MBSFN subframes on some types of carriers may contain non-MBSFN areas.

As long as the terminal knows the carrier type of the carrier to which the MBSFN subframe belongs, it can be known whether all the regions in the MBSFN subframe on the default carrier are MBSFN regions.

Optionally, after determining, by the terminal side, the carrier type of the carrier to which the MBSFN subframe belongs, whether the carrier type of the pre-configured carrier type and the MBSFN subframe are all pairs of the MBSFN area It should be determined whether all regions in the MBSFN subframe are MBSFN regions.

(1) If the unicast mode is used, the base station sends the MBSFN subframe indication information to the terminal. Specifically, the base station sends the dedicated signaling to the terminal, and the at least one cell type indication bit of the dedicated signaling carries the carrier type identifier.

That is, one or more indicator bits may be extended in the dedicated signaling sent by the base station to the terminal, for example, a cell type indication bit (ScellType), and the indicator type is used to identify the carrier type, for example, two carrier types need to be distinguished, and then the extension may be performed. An indication bit, the area of the MBSFN sub-frame on the carrier corresponding to the carrier type identified by the "1" is the MBSFN area; the MBSFN sub-frame on the carrier corresponding to the carrier type identified by the "0" is not the MBSFN area, that is, the MBSFN sub-area. The frame includes both an MBSFN area and a non-MBSFN area. Of course, if it is necessary to distinguish more carrier types, more indicator bits can be extended, and no limitation is imposed here.

(2) If it is a broadcast mode, the base station sends the MBSFN subframe indication information to the terminal, specifically: the base station broadcast system message, and the at least one cell type indication bit of the system message carries the carrier type identifier.

That is, one or more indicator bits, such as a cell type indicator bit (ScellType), may be extended in the system message broadcast by the base station, and the indicator type is used to identify the carrier type. For example, two carrier types need to be distinguished, and then one indicator bit may be extended. All the areas of the MBSFN sub-frames on the carrier corresponding to the carrier type identified by the "1" are all MBSFN areas; the MBSFN sub-frames on the carrier corresponding to the carrier type identified by the "0" are not all areas are MBSFN areas, that is, the MBSFN sub-frames include MBSFN area and non-MBSFN area. Of course, if it is necessary to distinguish more carrier types, more indicator bits can be extended, and no limitation is imposed here.

FIG. 4 is a schematic flowchart diagram of Embodiment 3 of a subframe configuration method according to the present invention.

The foregoing MBSFN subframe indication information may be a subframe type identifier. That is, the terminal distinguishes whether all areas in the MBSFN subframe are MBSFN areas according to the subframe type.

Correspondingly, as shown in FIG. 4, the terminal determines, according to the MBSFN subframe indication information, whether all the regions in the MBSFN subframe are MBSFN regions, and may include:

S401. The terminal determines, according to the foregoing subframe type identifier, a subframe type of the MBSFN subframe.

S402. The terminal determines, according to the subframe type of the MBSFN subframe, whether all regions in the MBSFN subframe are MBSFN regions.

After the terminal determines the subframe type of the MBSFN subframe, it can be based on the pre-configured correlation. The information knows whether all the areas in the MBSFN subframe are MBSFN areas.

The subframe structure corresponding to different subframe types is different, and the 4-seed frame structure is taken as an example:

The first MBSFN subframe structure includes an MBSFN area and a non-MBSFN area;

All areas in the second MBSFN subframe structure are MBSFN areas, that is, non-MBSFN areas are not included;

The third MBSFN subframe structure includes an MBSFN area and a non-MBSFN area, but is different from the subcarrier spacing in the first MBSFN subframe, and/or the cyclic prefix is different; and the terminal side receives the subframe type identifier, which can be based on the default. The configuration information is used to learn the specific subframe structure, and is not limited herein.

All the areas in the fourth MBSFN subframe structure are MBSFN areas, that is, do not include non-MBSFN areas, but are different from the subcarrier spacing in the second MBSFN subframe, and/or the cyclic prefix is different; the terminal side receives the subframe. The type identifier can be used to learn the specific subframe structure according to the default configuration information, which is not limited herein.

However, it is not limited to the above-mentioned MBSFN subframes, and can be flexibly configured according to actual conditions.

Optionally, the foregoing base station sends the subframe type identifier to the terminal, which may be a unicast mode or a broadcast mode.

(1) If the unicast mode is used, the base station sends the MBSFN subframe indication information to the terminal, where the base station sends the dedicated signaling to the terminal, and the at least one subframe type indication bit of the dedicated signaling carries the subframe type. Logo.

That is, one or more indicator bits may be extended in the dedicated signaling, and the indicator bit is used to identify the subframe type.

(2) If it is a broadcast mode, the base station sends the MBSFN subframe indication information to the terminal, specifically: the base station broadcast system message, where the at least one subframe type indication bit of the system message carries the subframe type identifier.

That is, one or more indicator bits may be extended in the above system message, and the indicator type is used to identify the subframe type.

Optionally, in the specific indication process, the subframe type of the MBSFN subframes in the radio frame may be uniformly indicated by the subframe type indication bit. In this case, the subframe types of all the MBSFN subframes in the radio frame are the same. That is, the at least one subframe type indication bit is used to indicate a subframe type of multiple MBSFN subframes in the radio frame. Taking the above four types of MBSFN subframes as an example, at least one subframe type indicator bit may be two indicator bits, 00 identifies a first type of MBSFN subframe, 01 identifies a second type of MBSFN subframe, and 10 identifies a third type of MBSFN subframe. , 11 identifies the fourth MBSFN subframe. If there are only 2 MBSFN subframe types, only one indicator bit may be needed. If there are more MBSFN subframe types, more indicator bits may be extended, which is not limited herein.

Optionally, in another mode, the at least one subframe type indication bit is corresponding to the foregoing MBSFN subframe, and is used to indicate a subframe type of the MBSFN subframe.

In this manner, each MBSFN subframe in the radio frame corresponds to at least one subframe type indication bit, that is, an indication sequence may be extended in the system message or the dedicated signaling, and at least one subframe type indication bit fixed in the sequence is unique. Indicates the subframe type of one of the MBSFN subframes.

Taking the 2 seed frame type as an example, each MBSFN subframe corresponds to one indicator bit, “1” identifies the first MBSFN subframe type, and “0” identifies the second MBSFN subframe type. Assuming that there are 8 MBSFN subframes in the radio frame, the indication sequence includes 8 bits, "001101" identifies 1, 2, 5, 3 MBSFN subframe bits, the second MBSFN subframe type, and 3, 4, and 6 MBSFN sub-frames. The frame is the first MBSFN subframe type. Of course, it is not limited to this. If it is a 2-seed frame type, then each of the MBSFN sub-frames corresponds to two indicator bits, which may be arranged in order.
