In order to facilitate the understanding of this application, the related concepts involved in the embodiments of this application are now described.

Multimedia Broadcast Multicast Service (MBMS) is a multimedia communication service for multiple user equipment (User Equipment, UE), which is referred to as multicast communication or MBMS communication in this embodiment of the application. Multicast communication can provide multiple user equipment with the same multimedia data within a large coverage area, such as live broadcast and scheduled broadcast programs.

Fifth generation mobile networks (5G): It is the latest generation of cellular mobile communication technology, and is an extension of fourth-generation mobile communication technology, third-generation mobile communication technology, and second-generation mobile communication technology. The performance goals of 5G are high data rates, reduced latency, energy savings, cost reduction, increased system capacity and large-scale device connections.

User Equipment (UE), which can also be called User Terminal (UT), Mobile Terminal (MT), Mobile Station (MS), etc., can be accessed via a radio access network (RadioAccess). Network, RAN) to communicate with one or more core networks. For example, the user equipment may be a mobile phone (or called a "cellular" phone) or a computer with a mobile terminal. For example, the user equipment may also be a portable, pocket-sized, hand-held, built-in computer or vehicle-mounted mobile device. Exchange voice and/or data with the wireless access network.

The base station can be the gNB (New Radio (NR) base station in the 5G system) in the 5G system, the Base Transceiver Station (BTS) in GSM or CDMA, or the base station in WCDMA ( It is called Node B), and may also be an evolved base station (called eNB or e-NodeB) in LTE.

In addition, a base station may support/manage one or more cells. When the user equipment needs to communicate with the network to obtain the MBMS service, the user equipment will select a cell to initiate network access.

In a 5G system, the gNB can be composed of a centralized unit (Centralized Unit, CU) and a distributed unit (Distributed Unit, DU).

The CU is mainly used for centralized wireless resource and connection management control, and has wireless high-level protocol stack functions, such as the RRC layer and the PDCP layer. CU can also support the sinking of part of the core network functions to the access network, called the edge computing network, which can meet the higher network delay requirements of emerging services (such as video, online shopping, virtual/augmented reality, etc.) in future communication networks. DU has distributed user plane processing functions, mainly with physical layer functions and layer 2 functions with higher real-time requirements.

The CU can be deployed in a centralized manner, and the deployment of the DU depends on the actual network environment. Exemplarily, for core urban areas, areas with high traffic density, small station spacing, or limited computer room resources, such as universities and large performance venues, CUs can be deployed in a centralized manner; Large areas, such as suburban counties, mountainous areas, etc., can deploy DUs in a distributed manner.

Correspondingly, the CU has an RRC layer and a PDCP layer, which are used for data encryption/decryption, integrity protection, and sorting functions. The DU has an RLC layer, a MAC layer and a PHY layer for feedback, scheduling, data packet segmentation and aggregation.

In order to enable those skilled in the art to better understand the technical solutions provided by the embodiments of the present invention, 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 description is The embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

The technical solution provided in this application can be applied to various communication systems, for example, it can be applied to fifth generation (5th generation mobile networks, 5G) communication systems, future evolution systems, or multiple communication convergence systems. The technical solution provided by this application can be applied to various application scenarios of the above-mentioned communication system, for example, enhanced mobile broadband (eMBB) communication, ultra-reliable&low latency communication, uRLLC) and massive machine type communication (mMTC) and other scenarios.

In order to implement SFN technology, first, different base stations need to negotiate time-frequency resource information, that is, to ensure that different base stations use the same time-frequency resources when sending MBMS services; second, on the same time-frequency resources, it is necessary to ensure that the transmission The data is the same, that is, data packet 0 is sent on resource 0, and data packet 1 is sent on resource 1. In this way, multiple base stations sending MBMS data are just like one base station sending MBMS data. If a UE is at the edge of coverage of a certain cell, the UE can receive signals from the current cell and neighboring cells. Since MBMS data is sent on the same time-frequency resource, the UE can receive two Or the superimposed MBMS data sent by more than two cells enhances the sending effect of MBMS.

To ensure that different base stations use the same resources as shown in Figure 1A, one way is to use a master node to allocate the same time-frequency resources to all slave nodes to ensure that the master node and all slave nodes have the same transmission Resource allocation, multiple slave nodes send the same MBMS data to multiple user equipments on the same frequency.

Wherein, the first device may be the aforementioned slave node or a unit on the slave node; the second device can be the aforementioned master node or a unit on the master node. The communication network may include multiple first devices and one second device. Further, the communication system may be used to implement MBMS communication, and the method may include the following steps:

301: The second device determines the time-frequency resource of the multicast transmission.

Optionally, the first device and the second device negotiate time-frequency resources for multicast transmission. It should be noted that this step 301 is optional, and the specific method for determining the time-frequency resource of the multicast transmission may include any of the following two methods, or other methods.

In multicast communication, the data transmitted by the first device to the user equipment includes MBMS data. Specifically, the second device sends MBMS data to multiple first devices, and the multiple first devices configure the same time-frequency resource according to the time-frequency resource configuration method, and send the same MBMS data to the same time-frequency resource. Different user equipment, so as to achieve multicast communication.

Wherein, the multiple frequency domain resources are frequency domain resources that can perform multicast transmission, and may be at least one frequency domain resource available to multiple first devices.

The specific implementation method for multiple first devices and/or second devices to determine (for example: negotiate) multiple time-frequency resources for multicast transmission may include the following steps. Illustratively, the following embodiments of the present application only use the first The device is a slave node, and the second device is the master node as an example, and the types of the first device and the second device are not specifically limited. The two methods will be introduced separately below.

The first one, as shown in Figure 4, the method may include:

301A: The first device sends second configuration information to the second device. The second configuration information may be used to indicate the time-frequency resources available to the first device or the time-frequency resources that have been occupied by the first device.

Wherein, the number of the first device may be multiple, that is, multiple first devices send corresponding second configuration information to the second device.

That is, the first device indicates to the second device the time-frequency resources available to the first device or the time-frequency resources already occupied by the first device.

In an alternative design, the first device indicates to the second device the time-frequency resources that have been occupied, so that the second device can use the time-frequency resources pre-configured by the second device for the first device and the time-frequency resources that have been occupied. Resources, determine the time-frequency resources available to the first device.

301B: The second device determines the first frequency domain resource set according to multiple second configuration information from multiple first devices.

Wherein, the first set of frequency domain resources includes a plurality of frequency domain resources. Specifically, the first frequency domain resource set is available to the multiple first devices.

The multiple pieces of second configuration information may specifically be multiple pieces of second configuration information from multiple first devices.

Taking the communication system shown in FIG. 1B as an example, the first device may be a slave node, and the second device may be a master node. Specifically, multiple slave nodes report to the master node the time-frequency resource information available or already occupied. The master control node obtains the available time-frequency resource information according to multiple sets of available time-frequency resource information reported by multiple slave nodes, or obtains the available time-frequency resource information according to the time-frequency resource information that has been occupied, and finally determines one or more sets of multiple slave nodes. Time-frequency resources used.

Among them, a group of time-frequency resources includes time-domain resources and frequency-domain resources. The time-domain resources may include the time period corresponding to the frequency-domain resources.

The second, as shown in Figure 5, the method may include:

301C: The second device sends third configuration information to the first device, and the third configuration information is used to configure multiple sets of time-frequency resources.

The third configuration information may include information about multiple sets of time-frequency resources that can be used by a certain type of multicast service, and the second device sends the third configuration information to multiple first devices.

That is to say, for example, when the first device is a slave node and the second device is the master node, the master node sends third configuration information to multiple slave nodes, and the third configuration information can be used to configure multiple groups of a certain type. Time-frequency resources used by the broadcast service.

301D: The first device sends instruction information to the second device, where the instruction information is used to indicate at least one set of time-frequency resources among the multiple sets of time-frequency resources, and the at least one set of time-frequency resources are time-frequency resources available to the first device.

Wherein, the first frequency domain resource set belongs to at least one group of time-frequency resources.

For example, when the first device is a slave node and the second device is the master node, after the slave node receives the third configuration information from the master node, it checks at least one set of time-frequency resources available to itself among multiple sets of time-frequency resources, And at least one group of available time-frequency resource information is fed back to the master control node.

301E: The second device determines a first set of frequency domain resources according to multiple time-frequency resources.

Specifically, the first frequency domain resource set is available to the multiple first devices.

Optionally, the multiple time-frequency resources include at least one set of time-frequency resources corresponding to each of the multiple first devices. Specifically, the second device determines the first set of frequency domain resources available to the multiple first devices according to at least one set of time-frequency resources corresponding to each of the multiple first devices.

For example, when the first device is a slave node and the second device is the master node, the master node receives instruction information from multiple slave nodes, and determines multiple slave nodes from the time-frequency resources available to the slave nodes carried in the instruction information. At least one set of time-frequency resources available to all nodes is used as the time-frequency resource in the first configuration information.

After multiple first devices and/or second devices determine the time-frequency resources available for multicast transmission, the first device determines the time-frequency resources for multicast transmission according to the size of the data to be sent. Further, the method includes the following steps:

302: The second device sends first configuration information to the first device, where the first configuration information is used to indicate a first frequency domain resource set, and the first frequency domain resource set includes multiple frequency domain resources.

Wherein, the first configuration information may be used to configure the multiple frequency domain resources. Optionally, the multiple frequency domain resources are multiple frequency domain resources that are negotiated between the second device and the multiple first devices and are available to the multiple first devices.

Further, the multiple frequency domain resources are configured periodically. Therefore, the first configuration information further includes the configuration periods and offsets of the multiple frequency domain resources described above. Wherein, the configuration period represents the time interval during which multiple frequency domain resources are available for configuration resources in the time domain. The configuration offset of the frequency domain resource is used to indicate the position where the frequency domain resource appears in the configuration period.

The location where frequency domain resources appear can be represented by a system frame number (SFN), for example, SFN is 01, 02, 03...11, 12, 13...21, 22, 23...wait. For example, if the configuration period is 10 ms and the offset is 2, the first device can calculate the system frame number in which the frequency domain resource appears according to the following formula;

The system frame number of the frequency domain resource %10=2, it can be obtained that the system frame number of the frequency domain resource is 02, 12, 22, etc. Among them,% is used to express modulo operation.

Exemplarily, as shown in FIG. 6, the master control node configures a plurality of periodic frequency resources, frequency resource 1, frequency resource 2, and frequency resource 3, to the slave node.

In an implementation manner, the first configuration information may further include a modulation mode. Among them, modulation is to ensure the communication effect and overcome the problems in long-distance signal transmission. The signal spectrum must be moved to the high-frequency channel for transmission through modulation. This process of loading the signal to be sent onto a high-frequency signal is called modulation.

In practical applications, the modulation method can be Quadrature Phase Shift Keying (Qpsk), 16 Quadrature Amplitude Modulation (16QAM), and 64 Quadrature Amplitude Modulation (64 Quadrature Amplitude Modulation). , 64QAM) and other methods. In different modulation modes of frequency domain resources, the size of the transmission data carried on the frequency domain resources may be different.

In an embodiment, the first configuration information may further include a coding rate. In the process of digital signal processing, it is often necessary to sample, quantize, and encode analog signals, and finally convert them into digital signals, which are then calculated and processed by computers. The coding rate is the proportion of useful information in the data stream after sampling, quantizing, and coding the analog signal. The coding rate is the proportion of the non-redundant part of the information in the data stream, that is, if the coding rate is k/n, for every k bits of useful information, the encoder generates a total of n bits of data, of which nk bits of data are redundant of.

In practical applications, under different coding rate configurations for frequency domain resources, the size of the transmission data carried on the frequency domain resources may be different.

303: The first device determines the target frequency domain resource from the multiple frequency domain resources according to the size of the data to be sent.

In an optional design, the data to be sent is the data that the first device needs to send to the user equipment at a certain time unit. In multicast communication, the data to be sent can be multicast data, for example, live broadcast or scheduled playback Video data. The multicast data to be sent may be multicast data from the second device (specifically, it may be the master node). The multiple first apparatuses send the same data to be sent on the same time-frequency resource to multiple different user equipments, so as to realize multicast communication.

The size of the data to be sent is the size of the data to be sent by the first device in the first time unit. For example, the size of the data to be sent by the first device at time N is 600 bits.

Further, the size of the data to be sent is determined in the second time unit, and the start time of the second time unit is before the first time unit. In other words, the size of the data to be sent at time N may be determined at time N-x before time N. Specifically, the first device can point to the data packet to be sent at time N according to the time information in all data packets received at time Nx and the previous time, and calculate the sum of all data packets to be sent at time N as time N the size of the data packet to be sent.

Wherein, time N-x may be the last time when the data packet to be sent at time N is received.

For example, the first device is a slave node. At the time Nx and the time before the time Nx, the slave node receives a total of 3 data packets. The transmission time indicated in the time is N. These three data packets plus the header each require 200 bits. (bit), 400 bits, 100 bits, then the size of the data to be sent at time N is 700 bits. The data packet may include a packet header and data. The packet header is some custom or preset data, and the packet header may be special characters added to the data encapsulation process. In the embodiment of the present application, the packet header may specifically be the transmission data. Different transport layer identification headers, for example, the PDCP header of the Packet Data Convergence Protocol (PDCP) layer, the RLC header of the Radio Link Control (RLC) layer, or the Media Access Control (Media Access Control (MAC) layer MAC header, etc.

Further, the first device determining the target frequency domain resource from the multiple frequency domain resources according to the size of the data to be sent may at least include the following two implementation solutions.

The first:

When the first configuration information further includes the transmission threshold corresponding to each of the multiple frequency domain resources, determining the target frequency domain resource from the multiple frequency domain resources according to the size of the data to be sent may include:

The first device determines the target frequency domain resource from the multiple frequency domain resources according to the size of the data to be sent and the threshold of the sent data.

Wherein, the transmission threshold corresponding to each frequency domain resource may be the maximum data transmission threshold corresponding to the frequency domain resource, or the minimum data transmission threshold corresponding to the frequency domain resource, or other possible thresholds. This application does not specifically limit this. In the following embodiments, the transmission threshold is taken as an example to describe the maximum data transmission threshold corresponding to frequency domain resources.

In particular, as another possible implementation method, the sending threshold may not be carried in the first configuration information. Instead, the first device is based on frequency domain resources, and the modulation mode and coding rate information corresponding to the frequency domain resources. The maximum amount of data that can be carried by the frequency domain resource is calculated, and the amount of data is used as the transmission threshold of the frequency domain resource. For example, if the frequency domain resource is 10 RBs and the modulation mode is Qpsk, the first device can calculate according to these parameters: 1 RB contains 12*12=144 frequency domain resource units, and each frequency domain resource unit can be based on Qpsk. Sending 2bit data, 10RB can send 144*10*2=2880bit data.

Specifically, the transmission threshold corresponding to the target frequency domain resource is greater than or equal to the size of the data to be sent, and the transmission threshold corresponding to the target frequency domain resource is the transmission threshold of at least one frequency domain resource greater than or equal to the size of the data to be sent The smallest and at least one frequency domain resource belongs to multiple frequency domain resources.

That is, the first device may select a transmission resource that is closest to and greater than or equal to the number of data bits to be sent from a plurality of frequency domain resources according to the size of the data to be sent. For example, the size of the data to be sent at time N is 700 bits, and the configuration of multiple frequency domain resources is shown in Table 1 below, where the frequency domain resource configuration can be represented by a collection of Resource Blocks (RB) blocks, for example , A certain frequency domain resource is configured as RB1-RB10.

Table 1

周期cycle	偏置Bias	频域资源Frequency domain resources	调制方式Modulation	发送门限Send threshold
10ms10ms	22	RB1-RB10RB1-RB10	QpskQpsk	1000比特1000 bits
10ms10ms	22	RB2-RB5RB2-RB5		QpskQpsk	200比特200 bits
10ms10ms	22	RB2-RB8RB2-RB8	QpskQpsk	800比特800 bits

Exemplarily, according to the first configuration information shown in Table 1, the first device selects the transmission threshold corresponding to the frequency domain resource that is closest to the size of the data to be sent, which is 700 bits, and is greater than or equal to the size of the data to be sent. The threshold is 800 bits, and the frequency domain resources RB2-RB8 corresponding to the threshold 800 bits are sent as the target frequency domain resources.

In the above-mentioned implementation manner, the first device can match the transmission resource corresponding to the closest transmission threshold capable of transmitting the data to be transmitted from multiple frequency domain resources according to the size of the data to be transmitted, thereby avoiding transmission resources. Waste.

The second type:

When the first configuration information further includes resource block RB sets of multiple frequency domain resources, determining the target frequency domain resource from the multiple frequency domain resources according to the size of the data to be sent may include:

The first device determines the first subset of the RB set according to the size of the data to be sent; the number of RBs included in the first subset is the number of the least RB used to carry the data to be sent.

Among them, the first subset of the RB set is the RB subset with the smallest number of RBs that can transmit data to be sent.

The specific determination of the number of RBs in the first subset may be: determining the minimum number of RBs required to transmit the data packet of the data to be sent according to the size of the data to be sent. Exemplarily, as shown in Table 2 below, 6 RBs can transmit data with a size of 500 bits, 7 RBs can transmit data with a size of 600 bits, and 8 RBs can transmit data with a size of 750 bits, then the data to be sent When the size of is 700 bits, the minimum number of RBs required for the first device to transmit data to be sent is 7. Then the first device may determine that the number of RBs in the first subset may be 7.

Table 2

6RBs6RBs	7RBs7RBs	8RBs8RBs	10RBs10RBs
500500	600600	750750	10001000

Then, the first device selects the RB with the least number of RBs used to carry the data to be sent from the pre-configured RB set in the order of the RB sequence number, and generates the first subset.

Wherein, the RB sequence number can be a continuous sequence number, for example, RB1, RB2, RB3..., or can be a discrete sequence number, for example, RB1, RB3, RB5...

The order of selecting and using RB sequence numbers from the RB set may be from top to bottom, or may be from bottom to top, and so on.

Exemplarily, as shown in Figure 7. The frequency domain resources configured by the master control node are RB sets: RB1, RB2, RB3...RB10, RB1 is at the bottom of the frequency domain resources, and RB10 is at the top of the frequency domain resources. And the selection order of the RB sequence numbers pre-configured on the slave node is from bottom to top. When the minimum number of RBs used to carry the data to be sent is 7, the slave node 1 can follow the order from bottom to top. RB1-RB8 are selected as the target frequency domain resources, and the slave node 2 may also select RB1-RB8 as the target frequency domain resources according to the order from bottom to top.

In the foregoing implementation manner, the first device can select the least required resource block capable of transmitting the data to be sent from the set of configured resource blocks according to the size of the data to be sent, effectively avoiding the waste of transmission resources.

304: The first device sends the data to be sent on the target frequency domain resource.

The first device sends the data to be sent to the terminal device according to the target frequency domain resource determined in step 303. Wherein, in the scenario of applying to a multicast communication service, the data to be sent may be MBMS data, and a plurality of different first devices all determine the same target frequency domain resource for sending the to-be-sent according to the same rule. data. Thereby, multiple first devices can send the same MBMS data to different terminal devices on the same time-frequency resource, realizing multicast service transmission, and avoiding the waste of transmission resources.

In the resource configuration method provided by the foregoing embodiment of the present application, the first device and the second device negotiate multiple frequency domain resource configurations that can be used to transmit multicast data. The first device selects multiple frequency domain resource configurations according to the size of the data to be sent. From the frequency domain resources, the smallest frequency domain resource configuration that can transmit the data to be sent is selected, thereby avoiding the waste of transmission resources.
