Description

MBSFN subframe configuration method, network equipment, terminal and storage medium
Technical Field
The embodiment of the application relates to the technical field of communication, in particular to a MBSFN (Multicast Broadcast Single Frequency Network multicast/multicast single frequency network) subframe configuration method, network side equipment, a terminal and a storage medium.
Background
The LTE MBMS (Long Term Evolution Multimedia Broadcast/Multicast Services, long term evolution multimedia broadcast/multicast service), also called eMBMS (Evolved Multimedia Broadcast/Multicast Services, evolved multimedia broadcast/multicast service) function, is a function introduced by the LTE (4G, 4 th generation) mobile communication system in the R9 stage, and the LTE MBMS function is carried in a broadcast manner, so that the content delivery efficiency is improved, and a multimedia broadcast service can be provided for users. Within the broadcast service area, the same MCS (Modulation and Coding Scheme, modulation and coding strategy) modulation class is uniformly used on MBSFN subframes configured to transmit broadcast subframes.
For the case that 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, in the scheme in the prior art, because the radio frame structure is fixed, the subcarrier spacing (SCS) is generally 15khz, the MBSFN subframe length is fixed to 1ms (millisecond), and the resource indication mode of the MBSFN subframe is relatively fixed.
However, in the next generation (e.g., 5G, 5 th generation) mobile communication system, the cell bandwidth block becomes larger, different frequency band cells support different bandwidths, the communication protocol supports multiple subcarrier spacings, the next generation mobile communication system still keeps applying the subcarrier spacing of 15KHz in some frequency bands (e.g., 700MHz, 1.8GHz, etc.), while other subcarrier spacings are mainly used in other frequency bands, e.g., the subcarrier spacing of 30KHz is mainly tried in the 2.6GHz frequency band, and the subcarrier spacing of the millimeter wave frequency band will be larger.
The larger subcarrier spacing will cause the granularity of resource allocation to be smaller, that is, the length of the basic scheduling unit (time slot or subframe) is reduced along with the larger subcarrier spacing, when the LTE MBMS service needs to be transmitted through more MBSFN subframes, the number of bits for indicating the MBSFN subframe allocation becomes larger, resulting in increased system overhead.

Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, fig. 1 shows a network structure schematic diagram provided in an embodiment of the present application, and as shown in fig. 1, the network structure schematic diagram includes a network side device 11 and a terminal 12. The network side device 11 may be a base station, for example, an evolved Node B (eNB), a macro station, a micro base station, or the like, and it should be noted that the specific type of the network side device 11 is not limited in the embodiment of the present application. The terminal 12 may be a mobile communication device such as a mobile phone, a tablet computer, a personal computer, a notebook computer, or a wearable device, and the specific type of the terminal 12 is not limited in the embodiment of the present application.
Referring to fig. 2, fig. 2 is a schematic diagram of a transmission mechanism of an LTE MBMS system in the prior art in a TDD (Time DivisionDuplexing, time division duplex) mode, and as shown in fig. 2, unicast service and LTE MBMS service are transmitted in isolation through time division multiplexing resources, that is, through different time slots, where a Guard Period (Guard Period) is GP, a downlink pilot time slot is DwPTS, an uplink pilot time slot is UpPTS, and LTE MBMS service is transmitted through an MBSFN subframe. In an LTE (Long Term Evolution ) system, when an MBSFN subframe is a subframe for carrying LTE MBMS broadcast data, the MBSFN subframe needs to occupy the entire bandwidth of a cell, and in a 4G system, the position where the MBSFN subframe occurs is given by SIB2 (system information block type2 message) of the 4G system, which is specifically expressed as follows:
in 5G NR (New Radio), the cell bandwidth block becomes large, and the medium-band cell supports 100MHz bandwidth, and the high-band cell supports 400MHz bandwidth. The communication protocol supports a plurality of subcarrier spacings, for example, the subcarrier spacings are lower than the 6GHz frequency band, the subcarrier spacings are selected from 15KHz, 30KHz or 60KHz, the subcarrier spacings are higher than the 6GHz frequency band, the subcarrier spacings are selected from 60KHz or 120KHz, the time slot lengths corresponding to different subcarrier spacings are different, and the following table 1 shows a plurality of different subcarrier spacings and the corresponding time slot lengths thereof:
TABLE 1
Subcarrier spacing 15KHz 30KHz 60KHz 120KHz 240KHz
Time slot length 1ms 0.5ms 0.25ms 0.125ms 0.0625ms
An increase in the subcarrier spacing will cause a smaller granularity of resource allocation, i.e. the length of the basic scheduling unit (e.g. the time slot in a 5G communication system or the subframe in a 4G communication system) decreases with an increase in the subcarrier spacing, and when LTE MBMS needs to be transmitted through more MBSFN subframes, the number of bits indicating MBSFN subframe allocation increases, resulting in an increase in system overhead.
Based on the technical background and the application environment, the MBSFN subframe configuration method provided by the application is described in detail below.
Referring to fig. 3, fig. 3 is one of flow diagrams of an MBSFN subframe configuration method provided by an embodiment of the present application, where the MBSFN subframe configuration method is applied to a network side device, as shown in fig. 3, and the MBSFN subframe configuration method includes:
step 301, a network side device determines resource indication information of an MBSFN subframe, wherein the MBSFN subframe is a subframe for transmitting an LTE MBMS, the resource indication information is at least used for indicating time domain information of the MBSFN subframe, and the time domain information takes a time slot as a basic unit.
In this step, before transmitting the LTE MBMS, the network side device determines resource indication information of an MBSFN subframe for transmitting the LTE MBMS, where the resource indication information is at least used to indicate time domain information of the MBSFN subframe, and the time domain information uses a time slot as a basic unit.
In the embodiment of the present application, the resource indication information may be used only for indicating time domain information of the MBSFN subframe, or may be used for indicating time domain information and frequency domain information of the MBSFN subframe, where the time domain information uses a time slot as a basic unit, and the frequency domain information uses a frequency as a basic unit.
Specifically, whether the LTE MBMS is transmitted on the full frequency band may be predefined, and then the resource indication information may be determined according to whether the ltebms is transmitted on the full frequency band. For example, if LTE MBMS is predefined (as explicitly specified by a specification or protocol) to be transmitted on the full frequency band, the network side device only needs to determine resource indication information only for indicating the time domain information of the MBSFN subframe. And if the predefined LTE MBMS is transmitted on the partial frequency band, the network side equipment determines the time domain information for indicating the MBSFN subframe and the resource indication information of the time domain information.
Step 302, the network side device sends the resource indication information to a 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 equipment can send the resource indication information to the terminal through signaling, for example, the resource indication information can be sent 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, a network side device determines resource indication information of an MBSFN subframe, where the MBSFN subframe is a subframe for transmitting an LTE MBMS, the resource indication information is at least used for indicating time domain information of the MBSFN subframe, and the time domain information uses a time slot as a basic unit; and the network side equipment sends the resource indication information to the terminal. In this way, the resource allocation granularity of the LTE MBMS service is performed by taking the time slot as a basic unit, so that the resource allocation granularity is flexible, the bit number for indicating the allocation of the MBSFN subframe can be effectively saved, and the system overhead is reduced.
Optionally, the MBSFN subframe is predefined to be transmitted on a full frequency band, and the resource indication information is used for indicating time domain information of the MBSFN subframe;
or, the MBSFN is predefined to be transmitted on a part of the frequency band, the resource indication information is used for indicating time domain information and frequency domain information of the MBSFN, and the frequency domain information takes frequency as a basic unit.
In this embodiment, whether the LTE MBMS is transmitted on the full frequency band may be predefined, and then the resource indication information may be determined according to whether the LTE MBMS is transmitted on the full frequency band. Specifically, LTE MBMS may be predefined to be transmitted on the full frequency band, or LTE MBMS may be predefined to be transmitted on the partial frequency band.
Specifically, if the LTE MBMS is predefined to be transmitted on the full frequency band, correspondingly, the bandwidth capability of the LTE MBMS terminal for radio frequency reception is the full frequency band, and the network side device only needs to notify the terminal of the time domain information of the MBSFN subframe, that is, the resource indication information determined by the network side device may be only used for indicating the time domain information of the MBSFN subframe.
For example, the time domain information of the MBSFN subframe may be indicated as follows:
if the LTE MBMS is predefined to be transmitted on a partial frequency band, correspondingly, the bandwidth capability of the LTE MBMS terminal for radio frequency reception is the partial frequency band, the network side device needs to notify the terminal of time domain information of the MBSFN subframe, and also needs to notify the terminal of frequency domain information of the MBSFN subframe, that is, the resource indication information determined by the network side device is used for indicating the time domain information and the frequency domain information of the MBSFN subframe, and the frequency domain information takes frequency as a basic unit.
For example, the time domain information of the MBSFN subframe may be indicated as follows:
the frequency domain information of the MBSFN subframe may be indicated as follows:
(1) If the MBMS service is transmitted only at one frequency domain position, the following is designed:
(2) If the MBMS service can be transmitted at a plurality of frequency domain locations, the following is designed:
regarding allocation of time domain (slot) resources, the following description is given with specific examples:
the TDD-UL-DL-Pattern (TDD uplink/downlink mode) period DL-UL-Transmission Periodicity (downlink/uplink transmission period) in 5G may be 0.5ms,0.625,1ms,1.25ms,2.5ms,3ms,4ms,5ms, and 10ms, and Pattern1 and Pattern2 double periods may be configured. But it is guaranteed that pattern1+ pattern2 is divisible by the radio frame period (i.e., 10 ms).
Taking 2.5ms monocycle 3D1U (configuration 2:3dl+dwpts+1ul) as an example, as shown in fig. 4, slot-pattern (Slot allocation) optional broadcast service MBSFN Slot position is (1, 2,3, 4), maxnrofslots=4, and Slot-pattern is "1111" if both are configured as broadcast service.
In this embodiment, the MBSFN subframe configuration method performs resource allocation with frequency and time slot as basic units for multiple bottom layer configurations in a communication system (such as 5G), so that the granularity of resource allocation of broadcast/multicast service can be effectively improved, the granularity of resource allocation is flexible, the number of bits for indicating MBSFN subframe allocation can be effectively saved, and the system overhead is reduced.
Optionally, the network side device sends the resource indication information to a terminal, including:
and the network side equipment sends the resource indication information to the terminal through a system broadcast message.
In this embodiment, the network side device sends the resource indication information to the terminal through a system broadcast message, for example, the resource indication information may be sent to the terminal through SIB (System Information Block ).
