Technical Field

Background

An LTE MBMS (Long Term Evolution Multimedia Broadcast/Multicast service), also called eMBMS (Evolved Multimedia Broadcast/Multicast service) function, is a function introduced by an LTE (4G, 4 th generation) mobile communication system at the stage R9, and the LTE MBMS function is carried in a Broadcast manner, thereby improving the delivery efficiency of content and providing a Multimedia Broadcast service for users. In the broadcast service area, the same MCS (Modulation and Coding Scheme) Modulation level is uniformly used on the MBSFN subframe configured to transmit the broadcast subframe.

In the scheme of the prior art, because the radio frame structure is fixed, the sub-carrier space (SCS) is generally 15KHZ, the length of the MBSFN subframe is fixed to 1ms (millisecond), and the resource indication mode of the MBSFN subframe is fixed.

However, in the next generation (e.g. 5G, 5 th generation) mobile communication system, the cell bandwidth becomes large, 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.), and mainly uses other subcarrier spacings in other frequency bands, e.g. 30KHz subcarrier spacing is tried in 2.6GHz band, and the subcarrier spacing in millimeter wave band will be larger.

The larger the subcarrier spacing, the smaller the resource allocation granularity, that is, the length of the basic scheduling unit (time slot or subframe) decreases with the larger the subcarrier spacing, and when the LTE MBMS service needs to be transmitted through more MBSFN subframes, the number of bits indicating MBSFN subframe allocation increases, which increases the system overhead.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic diagram of a network structure provided in an embodiment of the present invention, and as shown in fig. 1, the network structure 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, or a micro base station, and it should be noted that the specific type of the network side device 11 is not limited in this embodiment of the present invention. 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 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 an LTE MBMS system in the prior art adopts a TDD (Time division duplex) mode, and as shown in fig. 2, a unicast service and an LTE MBMS service are isolated and transmitted 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 the 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 appears is given by SIB2 (systemlnformationblocktype 2 message) of the 4G system, and the specific representation manner is as follows:

in 5G NR (New Radio, New air interface), a cell bandwidth block becomes large, a medium-band cell supports a 100MHz bandwidth, and a high-band cell supports a 400MHz bandwidth. The communication protocol supports various subcarrier intervals, for example, the subcarrier interval may be 15KHz, 30KHz or 60KHz and may be lower than a 6GHz band, the subcarrier interval may be 60KHz or 120KHz and may be higher than the 6GHz band, the time slot lengths corresponding to different subcarrier intervals are different, and table 1 below shows various different subcarrier intervals and their corresponding time slot lengths:

TABLE 1

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

The larger the subcarrier spacing, the smaller the resource allocation granularity, that is, the length of the basic scheduling unit (e.g. time slot in 5G communication system or subframe in 4G communication system) decreases with the larger the subcarrier spacing, and when the 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 above technical background and application environment, the MBSFN subframe configuring method provided by the present invention is described in detail below.

Referring to fig. 3, fig. 3 is a schematic flowchart of an MBSFN subframe configuring method provided in an embodiment of the present invention, where the MBSFN subframe configuring method is applied to a network side device, as shown in fig. 3, the MBSFN subframe configuring method includes:

step 301, a network side device determines resource indication information of an MBSFN subframe, wherein the MBSFN subframe is a subframe used 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 an LTE MBMS, the network side device determines resource indication information of an MBSFN subframe used for transmitting the LTE MBMS, where 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 embodiment of the present invention, 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 over a full frequency band may be predefined, and then the resource indication information may be determined according to whether the LTE MBMS is transmitted over the full frequency band. For example, if the LTE MBMS is predefined (e.g., explicitly specified by a specification or a protocol) to be transmitted in the full frequency band, the network-side device only needs to determine the resource indication information only for indicating the time domain information of the MBSFN subframe. If the predefined LTE MBMS is sent on a partial frequency band, the network side equipment determines time domain information used for indicating the MBSFN subframe and 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 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 the time domain information of the MBSFN subframe according to the resource indication information, and monitors and receives the 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 used for transmitting an evolved multimedia broadcast/multicast service 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; and the network side equipment sends the resource indication information to a terminal. Therefore, the resource allocation granularity of the LTE MBMS is carried out by taking the time slot as a basic unit, so that the resource allocation granularity is flexible, the bit number for indicating the MBSFN subframe allocation can be effectively saved, and the system overhead is reduced.

or, predefining the MBSFN for transmission on a partial frequency band, wherein 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 over a full frequency band may be predefined, and then the resource indication information may be determined according to whether the LTE MBMS is transmitted over the full frequency band. Specifically, LTE MBMS may be predefined to be transmitted in a full frequency band, or LTE MBMS may be predefined to be transmitted in a partial frequency band.

Specifically, if it is predefined that the LTE MBMS is transmitted in a full frequency band, and accordingly, the bandwidth capability of the LTE MBMS terminal for receiving radio frequency is the full frequency band, 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 only be used to indicate the time domain information of the MBSFN subframe.

For example, the time domain information of the MBSFN subframe may be indicated as follows:

if it is predefined that the LTE MBMS is transmitted on a partial frequency band, correspondingly, the bandwidth capability of the LTE MBMS terminal for radio frequency reception is a 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.

the frequency domain information of the MBSFN subframe may be indicated as follows:

(1) if the MBMS service is transmitted only in one frequency domain, the design is as follows:

(2) if the MBMS service can be transmitted in multiple frequency domain locations, the design is as follows:

regarding the allocation of time domain (time slot) resources, the following is illustrated with specific examples:

a TDD-UL-DL-Pattern period DL-UL-Transmission Periodicity (downlink/uplink Transmission period) in the 5G may be 0.5ms, 0.625, 1ms, 1.25ms, 2.5ms, 3ms, 4ms, 5ms, and 10ms, and a double period of Pattern1 and Pattern2 may be configured. However, it is ensured that the pattern1+ pattern2 is evenly divisible by the period (i.e., 10ms) of the radio frame (radio frame).

Taking 2.5ms monocycle 3D1U (configured 2: 3DL + DwPTS +1UL) as an example, as shown in fig. 4, Slot-pattern (Slot allocation) may select broadcast service MBSFN Slot position (1, 2, 3, 4), maxnRofSlots ═ 4, and if both are configured as broadcast service, Slot-pattern is "1111".

In this embodiment, the MBSFN subframe configuring method performs resource allocation with frequency and time slot as basic units for multiple bottom layer configurations in a communication system (e.g. 5G), so as to effectively improve the resource allocation granularity of broadcast/multicast services, enable the resource allocation granularity to be flexible, effectively save the number of bits for indicating MBSFN subframe allocation, and reduce system overhead.

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 an SIB (System Information Block).

Referring to fig. 5, fig. 5 is a second flowchart of an MBSFN subframe configuring method according to an embodiment of the present invention, where the MBSFN subframe configuring method is applied to a terminal, and as shown in fig. 5, the MBSFN subframe configuring method includes the following steps:

step 501, a terminal receives resource indication information of an MBSFN subframe sent by a network side device, wherein the MBSFN subframe is a subframe used 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.

Step 502, the terminal determines the time domain information of the MBSFN subframe according to the resource indication information, and monitors and receives the LTE MBMS service according to the time domain information.

In this embodiment, the terminal receives resource indication information of an MBSFN subframe sent by a network side device, where the MBSFN subframe is a subframe used 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; and the terminal determines the time domain information of the MBSFN subframe according to the resource indication information, and monitors and receives the LTE MBMS service according to the time domain information. Therefore, the time slot is used as a basic unit to carry out the resource allocation granularity of the LTE MBMS service, so that the resource allocation granularity is flexible, the bit number for indicating the MBSFN subframe allocation can be effectively saved, and the system overhead is reduced.
