For the case where the MBSFN subframe is a broadcast subframe for carrying LTE MBMS broadcast data, the MBSFN subframe needs to occupy the entire bandwidth of the cell.

For example, in the 2.6GHz frequency band, the subcarrier spacing of 30KHz is mainly used. big.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Referring to FIG. 1 , FIG. 1 shows a schematic diagram of a network structure provided by an embodiment of the present invention. As shown in FIG. 1 , it includes a network side device 11 and a terminal 12 . Wherein, the network side device 11 may be a base station, such as an evolved base station (eNB, evolved NodeB), a macro base station or a micro base station, etc. It should be noted that the specific type of the network side device 11 is not limited in the embodiment of the present invention. The terminal 12 may be a mobile phone, a tablet computer, a personal computer, a notebook computer, or a wearable device, which can perform mobile communication. It should be noted that the specific type of the terminal 12 is not limited in the embodiment of the present invention.

Referring to FIG. 2, FIG. 2 is a schematic diagram of a transmission mechanism in which the LTE MBMS system adopts TDD (Time Division Duplexing, Time Division Duplexing) mode in the prior art. As shown in FIG. Different time slots are used for isolated transmission, where the guard period (Guard Period) is GP, the downlink pilot time slot is DwPTS, the uplink pilot time slot is UpPTS, and the LTE MBMS service is transmitted through the MBSFN subframe. In the LTE (Long Term Evolution, Long Term Evolution) system, when the MBSFN subframe is used to carry LTE MBMS broadcast data, the MBSFN subframe needs to occupy the entire bandwidth of the cell. In the 4G system, the position where the MBSFN subframe appears It is given by SIB2 (SystemInformationBlockType2message, system information block type 2 message) of the 4G system, and its specific representation is as follows:

In 5G NR (New Radio, new air interface), the bandwidth block of the cell becomes larger, the mid-band cell supports 100MHz bandwidth, and the high-band cell supports 400MHz bandwidth. The communication protocol supports a variety of subcarrier intervals. For example, if the frequency band is lower than 6GHz, the subcarrier interval can be 15KHz, 30KHz or 60KHz, and if the frequency band is higher than 6GHz, the subcarrier interval can be 60KHz or 120KHz. Similarly, Table 1 below shows a variety of different subcarrier spacings and their corresponding slot lengths:

Table 1

subcarrier spacing 15KHz 30KHz 60KHz 120KHz 240KHz slot length 1ms 0.5ms 0.25ms 0.125ms 0.0625ms

The increase in the subcarrier spacing will result in a smaller resource allocation granularity, that is, the length of the basic scheduling unit (such as a time slot in a 5G communication system or a subframe in a 4G communication system) will shrink as the subcarrier spacing becomes larger. When LTE MBMS When more MBSFN subframes need to be transmitted, the number of bits indicating MBSFN subframe allocation increases, resulting in increased system overhead.

Based on the above technical background and application environment, the MBSFN subframe configuration method proposed by the present invention will be described in detail below.

Referring to FIG. 3, FIG. 3 is one of the flow diagrams of the MBSFN subframe configuration method provided by the embodiment of the present invention. The MBSFN subframe configuration method is applied to the network side device. As shown in FIG. 3, the MBSFN subframe configuration method include:

Step 301, the network side device determines the resource indication information of the MBSFN subframe, wherein the MBSFN subframe is a subframe used to transmit LTE MBMS, and the resource indication information is at least used to indicate the time domain information of the MBSFN subframe , the time domain information takes a time slot as a basic unit.

In this step, before the LTE MBMS is transmitted, the network side device determines the resource indication information of the MBSFN subframe used to transmit the LTE MBMS, and the resource indication information is at least used to indicate the time domain information of the MBSFN subframe , the time domain information takes a time slot as a basic unit.

Specifically, it may be pre-determined whether the LTE MBMS is sent on the whole frequency band, and then the resource indication information is determined according to whether the LTE MBMS is sent on the whole frequency band. For example, if it is predefined (such as specified by a specification or agreement) that LTE MBMS is sent on all frequency bands, the network side device only needs to determine the resource indication information only used to indicate the time domain information of the MBSFN subframe. If the predefined LTE MBMS is sent on some frequency bands, the network side device determines time domain information and resource indication information for indicating the MBSFN subframe.

Step 302, the network side device sends the resource indication information to the terminal.

In this step, the network side device sends the resource indication information to the terminal after determining the resource indication information of the MBSFN subframe. The network side device may send the resource indication information to the terminal through signaling, for example, may send the resource indication information to the terminal through a system broadcast message. The terminal receives the resource indication information, determines time domain information of the MBSFN subframe according to the resource indication information, and monitors and receives LTE MBMS according to the time domain information.

In this embodiment, the network side device determines the resource indication information of the MBSFN subframe, wherein the MBSFN subframe is a subframe used to transmit the evolved multimedia broadcast/multicast service LTE MBMS, and the resource indication information is at least used for Indicating the time domain information of the MBSFN subframe, where the time domain information takes a time slot as a basic unit; the network side device sends the resource indication information to the terminal. In this way, the resource allocation granularity of the LTE MBMS service is performed with the time slot as the basic unit, which makes the resource allocation granularity flexible, can effectively save the number of bits used to indicate MBSFN subframe allocation, and reduce system overhead.

For example, the time domain information of the MBSFN subframe may be indicated in the following manner:

The frequency domain information of the MBSFN subframe may be indicated in the following manner:

(1) If the MBMS service is only sent at one frequency domain location, the design is as follows:

(2) If the MBMS service can be sent at multiple frequency domain locations, the design is as follows:

Regarding the allocation of time domain (time slot) resources, the following uses specific examples to illustrate:

The TDD-UL-DL-Pattern (TDD uplink/downlink mode) period dl-UL-TransmissionPeriodicity (downlink/uplink transmission period) in 5G can be 0.5ms, 0.625, 1ms, 1.25ms, 2.5ms, 3ms, 4ms, 5ms and 10ms, and pattern1 and pattern2 double cycles can be configured. However, it is necessary to ensure that pattern1+pattern2 is divisible by the radioframe (wireless frame) period (ie 10ms).

Taking 2.5ms single-cycle 3D1U (configuration 2: 3DL+DwPTS+1UL) as an example, as shown in Figure 4, the Slot-pattern (time slot allocation) optional broadcast service MBSFN slot position is (1, 2, 3, 4 ), then maxnRofSlots=4, and if they are all configured as broadcast services, the slot-pattern is "1111".

In this embodiment, the MBSFN subframe configuration method is aimed at multiple underlying configurations in a communication system (such as 5G), and uses frequency and time slot as the basic unit for resource allocation, which can effectively improve the granularity of resource allocation for broadcast/multicast services , making resource allocation granularity flexible, effectively saving the number of bits used to indicate MBSFN subframe allocation, and reducing system overhead.

Optionally, the network side device sends the resource indication information to the terminal, including:
