Description

Resource allocation method and device

Technical Field

The present application relates to the field of communications, and in particular, to a method and an apparatus for resource allocation.

Background

Multimedia Broadcast Multicast Service (MBMS) is a Service for multiple users, such as live Broadcast, regularly playing programs, and the like, and can implement that when users in multiple cells are interested in the same media data, a network can transmit the same media data in the cells in a Single Frequency Network (SFN) manner, that is, it is necessary to negotiate available time-frequency resource information among different network devices to ensure that the same time-frequency resource is used when different network devices transmit MBMS services, and at the same time, it is required to ensure that the MBMS data transmitted by the multiple network devices are the same.

Currently, in implementing the SFN technology, one network device may be used as a master node, and the same time-frequency resource is allocated to all network devices used as slave nodes, so as to ensure that the master node and all slave nodes have the same transmission resource configuration. However, in the process of actually transmitting the multicast resource by the slave node, if the actually transmitted data is smaller than the transmission resource configuration, the invalid data needs to be filled, for example, the transmission resource configuration of the MBMS service can transmit 1000 bytes (byte) of data, but if the actually transmitted data only has 100 bytes (byte), the network device needs to fill 900 bytes (byte) of invalid data to occupy the time-frequency resource, which results in a waste of transmission resources.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.

To facilitate an understanding of the present application, reference will now be made to the description of the related concepts related to the embodiments of the present application.

Multimedia Broadcast Multicast Service (MBMS) is a Multimedia communication Service for multiple User Equipments (UEs), and in this embodiment, is referred to as Multicast communication or MBMS communication for short. Multicast communication can provide the same multimedia data for a plurality of user equipments over a wide coverage area, such as live broadcast, timed broadcast program, etc.

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

User Equipment (UE), which may also be referred to as a User Terminal (UT), a Mobile Terminal (MT), a Mobile Station (MS), etc., may communicate with one or more core networks via a Radio Access Network (RAN). The user equipment may be, for example, a mobile telephone (or so-called "cellular" telephone) or a computer with a mobile terminal, etc., and may also be, for example, a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device that exchanges voice and/or data with the radio access network.

The Base Station may be a gNB (Base Station using New Radio (NR) in the 5G system, a Base Transceiver Station (BTS) in GSM or CDMA, a Base Station (referred to as NodeB) in WCDMA, or an evolved node b (referred to as eNB or e-NodeB) in LTE.

In addition, one base station may support/manage one or more cells (cells), and when the user equipment needs to communicate with the network to acquire the MBMS service, the user equipment selects one cell to initiate network access.

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

The CU is mainly responsible for centralized radio resource and connection management control, and has functions of a radio high-level protocol stack, for example: RRC layer and PDCP layer, etc. The CU can also support partial core network functions to sink to an access network, called an edge computing network, and can meet higher requirements of emerging services (such as video, network shopping, virtual/augmented reality and the like) in a future communication network on network delay. The DU has a distributed user plane processing function, and mainly has a physical layer function and a layer 2 function with high real-time requirements.

CU can be deployed centrally and DU deployment depends on the actual network environment. For example, for a core metropolitan area, an area with a high traffic density, a small inter-site distance, or a limited machine room resource, for example: universities and large performance venues, CUs can be distributed in a centralized manner; for regions with sparser traffic, larger inter-site distances, etc., for example: in suburb county, mountain area, etc., DU can be distributed in a distributed manner.

Accordingly, the CU has an RRC layer and a PDCP layer, and is used for functions of ciphering/deciphering, integrity protection, sorting, and the like of data. The DU has an RLC layer, a MAC layer, and a PHY layer for feedback, scheduling, packet segmentation, concatenation, and the like.

In order to make those skilled in the art better understand the technical solutions provided by the embodiments of the present invention, 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 only a part of the embodiments of the present invention, and not all embodiments. 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.

The technical scheme provided by the application can be applied to various communication systems, such as: the method can be applied to a fifth generation (5G) communication system, a future evolution system or a plurality of communication fusion systems and the like. The technical solution provided by the present application may be applied to various application scenarios of the communication system, for example, scenarios such as enhanced mobile broadband (eMBB) communication, ultra high reliability and ultra low latency communication (urlclc), and massive internet of things communication (mtc).

The embodiments of the present application may be applied to a communication system as shown in fig. 1A, which may include a plurality of base stations 101 and a plurality of terminal devices 102, where the terminal devices 102 communicate with the base stations 101 through a communication channel 103. A plurality of different base stations provide the same multimedia data, e.g., live broadcast, timed broadcast programs, etc., to a plurality of UEs. When there are multiple cells in which users are interested in the same content, the communication network may transmit in the cells in a single frequency network sfn (single frequency network) manner. The SFN is formed by a plurality of radio transmitting stations in synchronization state at different locations, and transmits the same signal at the same time and the same frequency to realize reliable coverage to a certain service area.

As shown in fig. 1A, different base stations operate on the same frequency, and when transmitting MBMS, different base stations transmit the same MBMS data using the same time-frequency resource, so that different base stations transmit data as if one base station were transmitting data, and all user equipments in the area covered in the figure can receive the transmission of the MBMS data.

In order to implement the SFN technology, first, time-frequency resource information needs to be negotiated between different base stations, i.e. it is ensured that the same time-frequency resource is used when different base stations transmit MBMS services; secondly, on the same time-frequency resource, it is guaranteed that the transmitted data are the same, that is, data packet 0 is transmitted on resource 0, and data packet 1 is transmitted on resource 1, so that a plurality of base stations transmit MBMS data just as if one base station transmits MBMS data. If a certain UE is located at the edge covered by a certain cell, the UE may receive signals of the current cell and the neighboring cell, and because the MBMS data is transmitted on the same time-frequency resource, the UE may receive the superimposed MBMS data transmitted by two or more cells, thereby enhancing the transmission effect of the MBMS.

In order to ensure that different base stations use the same resources as shown in fig. 1A, one way is to allocate the same time-frequency resources to all the slave nodes by using one master node, so as to ensure that the master node and all the slave nodes have the same transmission resource allocation, and multiple slave nodes transmit the same MBMS data to multiple user equipments on the same frequency.

The master node may be a base station, or a logical function within a base station-CU, or a separate network node, such as a multicast coordinator node. In the embodiment of the present application, the master node may be a logical node, configured to control transmission synchronization of multiple slave nodes in one area, and as shown in fig. 1B, the master node may be placed in a gNB or a gNB-CU, or may be placed separately, which does not affect implementation of the present application.

The slave nodes can be base stations, base stations-DUs, or base stations-CUs and base stations-DUs. Wherein base station-CU and base station DU are considered together as one slave node.

Fig. 3 is a flowchart illustrating a method for resource allocation according to an embodiment of the present application, and the method for resource allocation according to the present application will be described with reference to the communication system shown in fig. 1B. The first device may be the above-mentioned slave node, or may be a unit on the slave node; the second device may be the above-mentioned master control node, and may also be a unit on the master control node. The communication network may comprise a plurality of first devices and a second device. Further, the communication system may be adapted to implement MBMS communication, and the method may comprise the steps of:

301: the second apparatus determines time-frequency resources for the multicast transmission.

Optionally, the first device negotiates with the second device for time-frequency resources for multicast transmission. It should be noted that, this step 301 is optional, and the specific manner of determining the time-frequency resource for multicast transmission may include any one of the following two manners, or may be another manner.

In multicast communication, data transmitted by a first device to user equipment contains MBMS data. Specifically, the second device may send MBMS data to the plurality of first devices, and the plurality of first devices configure the same time-frequency resource according to the time-frequency resource configuration method, and send the same MBMS data to different user equipments on the same time-frequency resource, thereby implementing multicast communication.

The time-frequency resources for multicast transmission may include time-frequency resources that are all available to the plurality of first apparatuses for transmitting MBMS data. The time-frequency resources of the multicast transmission may include a set of time-domain resources and a set of frequency-domain resources, the set of frequency-domain resources including a plurality of frequency-domain resources. The plurality of frequency domain resources may be frequency domain resources that may perform multicast transmission, and may be at least one frequency domain resource that is available to all of the plurality of first apparatuses.

A specific implementation method for determining (e.g., negotiating) multiple time-frequency resources for multicast transmission by multiple first devices and/or second devices may include the following steps, for example, the following embodiments of the present application only take the first device as a slave node and the second device as a master node as an example, and the types of the first device and the second device are not particularly limited. Two ways will be described separately below.

First, as shown in fig. 4, the method may include:

301A: the first apparatus sends second configuration information to the second apparatus, where the second configuration information may be used to indicate time-frequency resources available to the first apparatus or time-frequency resources already occupied by the first apparatus.

The number of the first apparatuses may be multiple, that is, multiple first apparatuses transmit corresponding second configuration information to the second apparatus.

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

In an alternative design, the first device may indicate the occupied time-frequency resources to the second device, so that the second device may determine the time-frequency resources available to the first device according to the time-frequency resources pre-configured for the first device by the second device and the occupied time-frequency resources.

301B: the second apparatus determines the first set of frequency domain resources according to a plurality of second configuration information from the plurality of first apparatuses.

Wherein the first set of frequency domain resources comprises a plurality of frequency domain resources. In particular, the first set of frequency domain resources is available to the plurality of first apparatuses.

The plurality of second configuration information may specifically be a plurality of second configuration information from a plurality of first apparatuses.

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, a plurality of slave nodes report available time-frequency resource information or occupied time-frequency resource information to the master node. The master control node obtains the available time frequency resource information according to the multiple groups of available time frequency resource information reported by the multiple slave nodes or according to the occupied time frequency resource information, and finally determines the time frequency resources which can be used by one or more groups of multiple slave nodes.

The group of time-frequency resources includes time-domain resources and frequency-domain resources, the time-domain resources may include time periods corresponding to the frequency-domain resources, and time units of the time-domain resources may be milliseconds, time slots, or other metering units for representing the time-domain resources.

Second, as shown in fig. 5, the method may include:

301C: and the second device sends third configuration information to the first device, wherein the third configuration information is used for configuring multiple groups of time frequency resources.

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

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

301D: the first device sends indication information to the second device, wherein the indication information is used for indicating at least one group of time frequency resources in the multiple groups of time frequency resources, and the at least one group of time frequency resources are available to the first device.

Wherein the first set of frequency domain resources 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 a master node, the slave node receives the third configuration information from the master node, checks at least one available time-frequency resource of the multiple sets of time-frequency resources, and feeds back the information of the at least one available time-frequency resource to the master node.

301E: the second device determines a first set of frequency domain resources from the plurality of time frequency resources.

In particular, the first set of frequency domain resources is available to the plurality of first apparatuses.

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

For example, when the first device is a slave node and the second device is a master node, the master node receives indication information from a plurality of slave nodes, and determines at least one group of time frequency resources available to all the slave nodes from the time frequency resources available to the slave nodes carried in the indication information, as the time frequency resources in the first configuration information.

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

302: the second apparatus sends first configuration information to the first apparatus, the first configuration information indicating a first set of frequency domain resources, the first set of frequency domain resources including a plurality of frequency domain resources.

Wherein the first configuration information may be used to configure the plurality of frequency domain resources. Optionally, the plurality of frequency domain resources are a plurality of frequency domain resources that are negotiated by the second apparatus and the plurality of first apparatuses and are available to the plurality of first apparatuses.

Further, the plurality of frequency domain resources are configured periodically, and therefore, the first configuration information further includes the configuration period and the offset of the plurality of frequency domain resources. Wherein the configuration period represents a time interval in which a plurality of frequency domain resources are available for configuring resources in a time domain. The configuration offset of the frequency domain resources is used to indicate the position of the frequency domain resources occurring within the configuration period.

The locations where the frequency domain resources occur may be represented by a System Frame Number (SFN), for example, SFN is 01, 02, 03. For example, if the configuration period is 10ms and the offset is 2, the first device may calculate the system frame number of the frequency domain resource according to the following formula;

the system frame number% 10 of the frequency domain resource is 2, and the system frame number of the frequency domain resource is 02, 12, 22. Where,% is used to denote the modulo operation.

Illustratively, as shown in fig. 6, the master node configures a plurality of frequency resources, frequency resource 1, frequency resource 2 and frequency resource 3, to the slave node periodically.

In one embodiment, the first configuration information may further include a modulation scheme. The modulation is to ensure the communication effect, overcome the problem in the long-distance signal transmission, and move the signal spectrum to a high-frequency channel for transmission through modulation. This process of loading the signal to be transmitted into the high frequency signal is called modulation.

In practical applications, the Modulation scheme may be Quadrature Phase Shift Keying (Qpsk), 16 Quadrature Amplitude Modulation (16 QAM), 64Quadrature Amplitude Modulation (64 QAM), or the like. The frequency domain resources are in different modulation modes, and the sizes of transmission data carried on the frequency domain resources may be different.

In one embodiment, the first configuration information may further include a coding rate. In the process of digital signal processing, sampling, quantization and coding processing are often required to be performed on an analog signal, and the analog signal is finally converted into a digital signal and then subjected to calculation processing by a computer. The coding rate is the ratio of the useful information part in the data stream after sampling, quantizing and coding the analog signal. The coding rate is the proportion of non-redundant part information in the data stream, i.e. if the coding rate is k/n, the encoder generates a total of n bits of data for every k bits of useful information, where n-k bits of data are redundant.

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

303: the first device determines a target frequency domain resource from a plurality of frequency domain resources according to the size of data to be transmitted.

In an alternative design, the data to be sent is data that the first device needs to send to the user equipment in a certain time unit, and in the multicast communication, the data to be sent may be multicast data, for example, video data that is live broadcast or played regularly. The multicast data to be transmitted may be multicast data from a second device (which may be a master node in particular). The first devices transmit the same data to be transmitted to the different user equipment on the same time-frequency resource, and multicast communication can be realized.

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

Further, the size of the data to be transmitted is determined in a second time unit, the start time of which is before the first time unit. That is, the size of the data to be transmitted at time N may be determined at time N-x before time N. Specifically, the first device may calculate, according to the data packet to be sent at time N and carrying the time information in all the data packets received at time N-x and previous time, that the sum of all the data packets to be sent at time N is the size of the data packet to be sent at time N.

Where, time N-x may be the last time a packet to be transmitted at time N is received.

For example, the first device is a slave node, and at times N-x and before N-x, the transmission times indicated in the total reception of 3 data packets by the slave node are all N times, and if the three data packets plus the header respectively require 200 bits (bit), 400 bits, and 100 bits, the size of the data to be transmitted at N times is 700 bits. In this embodiment of the present application, the Packet header may specifically be an identification Packet header of transmission Data in different transmission layers, for example, a Packet Data Convergence Protocol (PDCP) header of a PDCP layer, an RLC header of a Radio Link Control (RLC) layer, or a MAC Packet header of a Media Access Control (MAC) layer.

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

The first method comprises the following steps:

when the first configuration information further includes a transmission threshold corresponding to each of the plurality of frequency domain resources, determining a target frequency domain resource from the plurality of frequency domain resources according to the size of data to be transmitted may include:

the first device determines a target frequency domain resource from the plurality of frequency domain resources according to the size of data to be transmitted and a threshold for transmitting the data.

The sending threshold corresponding to each frequency domain resource may be a threshold of maximum data transmission corresponding to the frequency domain resource, a threshold of minimum data transmission corresponding to the frequency domain resource, or other possible threshold values.

Specifically, as another possible implementation method, the sending threshold may not be carried in the first configuration information, but the first device calculates the maximum data amount that can be carried by the frequency domain resource according to the frequency domain resource, and the modulation method and the coding rate information corresponding to the frequency domain resource, and uses the data amount as the sending threshold of the frequency domain resource. For example, the frequency domain resource is 10 RBs, and the modulation scheme is Qpsk, the first apparatus may calculate: 1 RB contains 12 × 144 frequency domain resource units, each frequency domain resource unit can transmit 2-bit data according to Qpsk, and 10RB can transmit 144 × 10 × 2 ═ 2880-bit 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 transmitted, and the transmission threshold corresponding to the target frequency domain resource is the smallest of the transmission thresholds of at least one frequency domain resource that is greater than or equal to the size of the data to be transmitted, and at least one frequency domain resource belongs to a plurality of frequency domain resources.

That is, the first device may select, according to the size of the data to be transmitted, one transmission resource that is closest to and greater than or equal to the number of bits of the data to be transmitted from the multiple frequency domain resources for use. For example, the size of data to be transmitted at time N is 700 bits, and the configuration of a plurality of frequency domain resources is shown in table 1 below, where the frequency domain Resource configuration may be represented by a set of Resource Blocks (RBs), for example, a certain frequency domain Resource configuration is RB1-RB 10.

TABLE 1

Period of time	Biasing	Frequency domain resources	Modulation system	Transmission threshold
					10ms	2	RB1-RB10	Qpsk	1000 bits
10ms	2	RB2-RB5	Qpsk							200 bit
					10ms	2	RB2-RB8	Qpsk	800 bits of

Illustratively, according to the first configuration information shown in table 1, the first device selects, as the target frequency domain resource, a frequency domain resource RB2-RB8 corresponding to 800 bits of a transmission threshold corresponding to the frequency domain resource, where the transmission threshold is closest to 700 bits of the size of the data to be transmitted and is greater than or equal to the size of the data to be transmitted.

In the above embodiment, the first device may match, according to the size of the data to be transmitted, the transmission resource corresponding to the closest transmission threshold capable of transmitting the data to be transmitted from the multiple frequency domain resources for use, so as to avoid waste of the transmission resource.

And the second method comprises the following steps:

when the first configuration information further includes resource block RB sets of a plurality of frequency domain resources, determining a target frequency domain resource from the plurality of frequency domain resources according to the size of data to be transmitted may include:

the first device determines a first subset of the RB set according to the size of data to be sent; the number of RBs included in the first subset is the minimum number of RBs used for carrying data to be transmitted.

The first subset of the RB set is the RB subset with the minimum number of RBs and capable of transmitting data to be transmitted.

Specifically, the determining the number of RBs in the first subset may be: and determining the minimum RB number required for transmitting a data packet of the data to be transmitted according to the size of the data to be transmitted. For example, 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, and when the size of the data to be transmitted is 700 bits, the minimum required number of RBs through which the first device can transmit the data to be transmitted is 7. The first device may determine that the number of RBs in the first subset may be 7.

TABLE 2

6RBs	7RBs	8RBs	10RBs
				500	600	750	1000

Then, the first device selects the RB with the minimum number of RBs for carrying data to be sent from the pre-configured RB set according to the sequence of RB sequence numbers, and generates a first subset.

The RB sequence numbers may be consecutive ones, for example, RB1, RB2, and RB3 … …, or discrete ones, for example, RB1, RB3, and RB5 … ….

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

Exemplarily, as shown in fig. 7. The frequency domain resource configured by the master control node is an RB set: RB1, RB2, RB3 … … RB10, RB1 being the lowest of the frequency domain resources and RB10 being the highest of the frequency domain resources. And the selection sequence of the RB sequence numbers pre-configured on the subordinate nodes is from bottom to top, when the minimum number of RBs for carrying data to be sent is 7, the subordinate node 1 may select RBs 1-RB8 as target frequency domain resources according to the sequence from bottom to top, and the subordinate node 2 may also select RBs 1-RB8 as target frequency domain resources according to the sequence from bottom to top.

In the above embodiment, the first device may select, according to the size of the data to be transmitted, the least required resource block capable of transmitting the data to be transmitted from the configured resource block set, so as to effectively avoid waste of transmission resources.

304: the first device transmits data to be transmitted on the target frequency domain resource.

The first device sends data to be sent to the terminal equipment according to the target frequency domain resource determined in step 303. In a scenario of being applied to a multicast communication service, the data to be transmitted may be MBMS data, and a plurality of different first devices determine, according to the same rule, the same target frequency domain resource to be used for transmitting the data to be transmitted. Therefore, the first devices can send the same MBMS data to different terminal equipment in the same time-frequency resource, the multicast service transmission is realized, and the waste of transmission resources is avoided.

In the method for resource allocation provided in the foregoing embodiment of the present application, a plurality of frequency domain resource allocations that can be used for transmitting multicast data are negotiated through the first device and the second device, and the first device selects the smallest frequency domain resource allocation that can transmit data to be transmitted from the plurality of frequency domain resources according to the size of the data to be transmitted, thereby avoiding waste of transmission resources.
