Description

Method and device for resource allocation

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for resource allocation.

Background

For a 5G NR (New Radio, New air interface) system, the core network may configure a QoS (Quality of Service) Profile for each Flow. The RAN (Radio Access Network, Access Network) performs QoS management for QoS Profile configured for each Flow based on the core Network. One parameter in QoS profile is 5QI (5G QoS Identifier, fifth generation mobile communication system quality of service Identifier). MDBV (Maximum Data Burst Volume) is one parameter contained in 5 QI. While the 5G NR system mainly supports three types of services: the first is an enhanced Mobile Broadband (eMBB) service, the second is a massive Machine Type communication (mtc) service, and the third is a very high-reliability and Low-Latency communication (URLLC) service.

Among them, URLLC traffic has a relatively high delay requirement, and is therefore generally referred to as delay-sensitive GBR traffic. For such services, when the core network defines QoS profile based on Flow, the 5QI generally includes MDBV parameters, where MDBV indicates the maximum amount of data that the 5G access network needs to handle one Flow within the PDB time range, and the 5QI may be standardized or non-standardized.

However, there is no clear solution for the resource allocation method based on MDBV data transmission in the prior art for the 5G system.

Disclosure of Invention

The invention provides a method and a device for resource allocation, which are used for solving the problem that no clear solution is available for a resource allocation method based on MDBV data transmission in a 5G system in the prior art.

In the first aspect, a terminal determines an MDBV corresponding to a logical channel and a token bucket for MDBV control; and then performing resource allocation on the logical channel according to the determined MDBV and the token bucket for MDBV control.

In the embodiment of the invention, the terminal firstly determines the MDBV corresponding to the logical channel and the token bucket used for MDBV control, and then performs resource allocation for the logical channel according to the determined MDBV and the token bucket used for MDBV control. In the embodiment of the invention, the resources for data transmission are distributed according to the token bucket for MDBV control, so that the data volume sent by each QoS Flow is ensured not to exceed the MDBV limit, and the delay sensitive service is prevented from preempting the resources of other services when the system load is heavier.

In some specific implementations, after the terminal determines that the logical channel is established, determining an MDBV corresponding to the logical channel and a token bucket for MDBV control; and/or after the terminal receives a notification which is sent by the network side equipment and needs to allocate resources based on the MDBV, determining the MDBV corresponding to the logical channel and a token bucket used for controlling the MDBV.

In some specific implementations, the terminal determines, in a Medium Access Control (MAC) layer, an MDBV corresponding to a logical channel according to a mapping relationship between a Flow and the logical channel.

In some embodiments, if the Flow and logical channels use 1:1, mapping, wherein the terminal takes the MDBV corresponding to the Flow as the MDBV corresponding to the logic channel; or

If the Flow and the logic channel adopt M:1 mapping, the terminal takes the sum of MDBVs corresponding to the Flow which can be mapped to the logic channel as the MDBVs corresponding to the logic channel according to the mapping relation of the Flow and the logic channel; or

If the Flow and the logic channel adopt M:1 mapping, the terminal takes the sum of MDBV corresponding to the Flow actually mapped to the logic channel as the MDBV corresponding to the logic channel according to the mapping relation of the Flow and the logic channel; wherein M is a positive integer.

In the embodiment of the invention, the terminal determines the MDBV corresponding to the logic channel according to different conditions, so that the reasonable resource allocation is ensured during resource allocation, and the delay sensitive service is prevented from preempting the resources of other services.

In some specific implementations, before a terminal determines an MDBV corresponding to an object through an MAC layer, the terminal needs to notify a mapping relationship between a Flow and a logical channel of the MAC layer through an SDAP (Radio Resource Control) or RRC (Radio Resource Control) layer; or

The terminal informs the mapping relation between the Flow and the logic channel of the MAC layer and the MDBV corresponding to the QFI through the SDAP or the RRC layer; or

The terminal informs the MAC layer of the Flow actually mapped to the logic channel through the SDAP layer; or

The terminal informs the MAC layer of MDBV corresponding to Flow and QFI actually mapped to the logic channel through the SDAP layer; or

And after the terminal informs the MDBV corresponding to the logic channel of the MAC layer through the SDAP layer, the MDBV corresponding to the object is determined through the MAC layer.

In the embodiment of the invention, as the terminal is the MDBV corresponding to the logical channel determined by the MAC layer, but the MAC layer does not know the corresponding mapping relation, a plurality of ways of informing the MAC layer are introduced, thereby being more diversified and ensuring that the terminal can determine the MDBV corresponding to the logical channel at the MAC layer.

In the embodiment of the invention, as the terminal is the MDBV corresponding to the logical channel determined by the MAC layer, but the MAC layer does not know the corresponding mapping relation, a plurality of ways of informing the MAC layer are introduced to ensure that the terminal can determine the MDBV corresponding to the logical channel at the MAC layer.

In some implementations, the token bucket for MDBV control is sized for an MDBV for a logical channel. The terminal determines the number M of tokens which are actually used in a token bucket for MDBV control in a logical channel within a time period (N-PDB, N), and takes the difference between the size of the token bucket and the M as the number of available tokens in the token bucket corresponding to the logical channel, wherein N is scheduling time, and PDB is data packet delay budget corresponding to the logical channel.

In some specific implementations, the terminal determines the PDB corresponding to the logical channel by:

determining 5 QIs corresponding to all flows which can be mapped to the logic channel or 5 QIs corresponding to all flows which are actually mapped to the logic channel according to the logic channel and the Flow mapping relation; and determining the maximum PDB as the PDB corresponding to the logic channel according to the 5QI corresponding to the Flow.

In the embodiment of the invention, the number of the available tokens in the token bucket corresponding to the logical channel is determined according to the size of the token bucket for MDBV control and the number of the tokens actually used in the token bucket for determining the logical channel for MDBV control in the time period (N-PDB, N), and the resource allocation is carried out according to the number of the available tokens in the token bucket corresponding to the determined logical channel, so that the data volume sent by each QoS Flow is fully ensured not to exceed the MDBV limit, and the delay sensitive service is prevented from preempting the resources of other services when the system load is heavy.

In some implementations, in allocating resources, for logical channels with MDBV requirements:

step 1: the terminal sorts the logic channels with available PBR tokens and data transmission requirements according to a logic channel priority descending order, then sequentially performs first round resource allocation on each logic channel based on PBR, simultaneously updates the number of tokens in a PBR token bucket corresponding to each logic channel, and simultaneously updates the number of available tokens in an MDBV token bucket corresponding to the logic channel after completing PBR-based resource allocation on the logic channel;

step 2: after determining that the remaining resources exist, the terminal performs a second round of resource allocation on all the logical channels with the data transmission requirements according to the descending order of the logical channel priorities:

for a logic channel with MDBV requirement, in the second round of resource allocation process, taking the data amount of the allowed allocated resources of the logic channel as the smaller value of the available token number in a token bucket used for MDBV control by the logic channel and the data amount of the resources to be allocated currently by the logic channel, and allocating the resources to the logic channel; and if the logical channel needing to be allocated currently is the logical channel without the MDBV requirement, the terminal allocates the resources to the logical channel according to the data volume of the resources to be allocated currently of the logical channel.

And step 3: and if the terminal determines that the residual resources exist, performing resource allocation on the residual data to be transmitted according to the descending order of the priority of all the logic channels with the data transmission requirements until the resources are exhausted or the resources are allocated to the data to be transmitted of all the logic channels.

And when allocating resources, for the logical channels without MDBV requirement:

step 1: the terminal sorts the logic channels with available PBR tokens and data transmission requirements according to a logic channel priority descending order, then sequentially performs first round resource allocation on each logic channel based on PBR, simultaneously updates the number of tokens in a PBR token bucket corresponding to each logic channel, and simultaneously updates the number of available tokens used for MDBV control of the logic channel with MDBV requirements after completing PBR-based resource allocation;

for a logic channel with MDBV requirement, in the second round of resource allocation process, taking the data amount of the allowed allocated resources of the logic channel as the smaller value of the available token number in a token bucket used for MDBV control by the logic channel and the data amount of the resources to be allocated currently by the logic channel, and allocating the resources to the logic channel; if the current logical channel needing to be allocated is the logical channel without MDBV requirement and containing GBR (guaranteed Bit Rate) service, the terminal allocates resources to the logical channel;

and step 3: and if the terminal determines that the residual resources exist, the terminal performs resource allocation on the residual data to be transmitted according to the descending order of the priority of all the logic channels with the data transmission requirements until the resources are exhausted or the resources are allocated to the data to be transmitted of all the logic channels.

The number of the tokens which can be used in the token bucket for MDBV control corresponding to the logical channel is the difference value between the MDBV corresponding to the logical channel and the number of the tokens which have been actually used in the token bucket for MDBV control corresponding to the logical channel.

The terminal determines the number M of tokens which are actually used in a token bucket for MDBV control by a logical channel within a time period (N-PDB, N), and the difference value between the size of the token bucket and the M is used as the number of available tokens in the token bucket corresponding to the object, so that the purpose of updating the number of available tokens in the token bucket for MDBV control by the logical channel with MDBV requirements after PBR-based resource allocation is completed is achieved.

In the embodiment of the invention, when the resources are allocated, different modes are adopted for the logic channel without the MDBV requirement and the logic channel with the MDBV requirement, so that the data volume sent by each QoS Flow is further ensured not to exceed the MDBV limit, and the time delay sensitive service is prevented from preempting the resources of other services when the system load is heavier.

In a second aspect, an embodiment of the present invention provides a method for resource allocation, where the method includes:

the network side equipment determines an MDBV corresponding to the resource allocation object and a token bucket for controlling the MDBV; then the network side equipment performs resource allocation on the resource allocation object according to the determined MDBV and the token bucket for MDBV control; if uplink resource allocation is carried out, the resource allocation object is a logical channel group; and if the downlink resource allocation is carried out, the resource allocation object is a logical channel.

According to the method, the network side equipment determines the MDBV corresponding to the resource allocation object and the token bucket used for MDBV control, and then performs resource allocation on the resource allocation object according to the determined MDBV and the token bucket used for MDBV control. In the embodiment of the invention, the resources for data transmission are distributed according to the token bucket for MDBV control, so that the data volume sent by each QoS Flow is ensured not to exceed the MDBV limit, and the delay sensitive service is prevented from preempting the resources of other services when the system load is heavier.

In some specific implementations, after the network side device determines that the establishment of the logical channel is completed, it determines an MDBV and a token bucket for MDBV control, which correspond to the resource allocation object; and/or determining the MDBV corresponding to the resource allocation object and a token bucket for controlling the MDBV after determining that the resource allocation needs to be carried out based on the MDBV according to the system load.

And if the uplink resource allocation is carried out, the network side equipment informs the terminal of the resource allocation needing to be carried out based on the MDBV after determining that the resource allocation needs to be carried out based on the MDBV according to the system load.

In the embodiment of the invention, because the network side equipment determines the MDBV corresponding to the logic channel according to different conditions, the reasonable resource allocation is ensured during resource allocation, and the time delay sensitive service is prevented from preempting the resources of other services.

In some specific implementations, if downlink resource allocation is performed, the network side device determines an MDBV corresponding to a logical channel according to a mapping relationship between Flow and the logical channel; or

If uplink resource allocation is carried out, the network side equipment determines the MDBV corresponding to the logic channel according to the mapping relation between the Flow and the logic channel, and takes the sum of the MDBVs corresponding to the logic channels in the same logic channel group as the MDBV corresponding to the logic channel group; or

If uplink resource allocation is carried out, the network side equipment takes the sum of MDBVs corresponding to the logical channels reported by the terminal as the MDBV corresponding to the logical channel group; or

And if the uplink resource allocation is carried out, the network side equipment receives the MDBV corresponding to the logical channel group reported by the terminal.

In some implementations, if the Flow and logical channels use 1:1, the network side equipment takes the MDBV corresponding to the Flow as the MDBV corresponding to the logic channel; or

If the Flow and the logic channel adopt M:1 mapping, the network side equipment takes the sum of MDBVs corresponding to the Flow which can be mapped to the logic channel as the MDBVs corresponding to the logic channel according to the mapping relation of the Flow and the logic channel; or

If the Flow and the logic channel adopt M:1 mapping, the network side equipment takes the sum of MDBV corresponding to the Flow actually mapped to the logic channel as the MDBV corresponding to the logic channel according to the mapping relation of the Flow and the logic channel; wherein M is a positive integer.

In some specific implementations, before a network side device determines an MDBV corresponding to a resource allocation object through an MAC layer, the network side device needs to notify a mapping relationship between a Flow and a logical channel of the MAC layer through an SDAP (Radio resource control) or RRC (Radio resource control) layer; or

The network side equipment informs the mapping relation between the Flow and the logic channel of the MAC layer and the MDBV corresponding to the QFI through the SDAP or the RRC layer; or

The network side equipment informs the MAC layer of the Flow actually mapped to the logic channel through the SDAP layer; or

The network side equipment informs the MAC layer of MDBV corresponding to Flow and QFI actually mapped to the logic channel through the SDAP layer; or

And after the network side equipment informs the MDBV corresponding to the logic channel of the MAC layer through the SDAP layer, determining the MDBV corresponding to the resource allocation object through the MAC layer.

In some specific implementations, when performing uplink resource allocation, the MAC layer does not know the mapping relationship between the logical channel and the logical channel group, and therefore the RRC layer also needs to notify the mapping relationship between the logical channel and the logical channel group of the MAC layer, so that the network side device can determine the MDBV corresponding to the logical channel group in the MAC layer.

In some specific implementations, if the resource allocation pair is a logical channel group, the network side device notifies, through the RRC layer, a mapping relationship between a MAC layer logical channel and the logical channel group.

In the embodiment of the invention, because the network side equipment is the MDBV corresponding to the logical channel determined in the MAC layer, but the MAC layer does not know the corresponding mapping relation, a plurality of ways of informing the MAC layer are introduced to ensure that the network side equipment can determine the MDBV corresponding to the logical channel in the MAC layer.

In some implementations, the token bucket for MDBV control is sized for an MDBV for a logical channel. The network side equipment determines the number M of tokens which are actually used in a token bucket for MDBV control by a logical channel in a time period (N-PDB, N), and takes the difference between the size of the token bucket and the M as the number of available tokens in the token bucket corresponding to the logical channel, wherein N is scheduling time, and PDB is data packet delay budget corresponding to the logical channel.

In some specific implementations, the network side device determines the PDB corresponding to the logical channel by:

In the embodiment of the invention, the number of the available tokens in the token bucket corresponding to the resource allocation object is determined according to the size of the token bucket for MDBV control and the number of the tokens actually used in the token bucket for determining the resource allocation object for MDBV control in the time period (N-PDB, N), and the resource allocation is carried out according to the number of the available tokens in the token bucket corresponding to the determined resource allocation object, so that the data volume sent by each QoS Flow is fully ensured not to exceed the MDBV limit, and the time delay sensitive service is prevented from preempting the resources of other services when the system load is heavier.

In some specific implementations, if downlink resource allocation is performed, the network side device takes a difference between the MDBV corresponding to the logical channel and the number of tokens that have been actually used in the token bucket for MDBV control as a data amount of resources that can be allocated by the logical channel; and then performing resource allocation on the logic channel according to the minimum value between the number of available tokens in a token bucket corresponding to the logic channel MDBV and the actual data volume to be transmitted of the current logic channel.

In some specific implementations, if uplink resource allocation is performed, the network side device takes a difference between the MDBV corresponding to the logical channel group and the number of actually used tokens in the token bucket for MDBV control corresponding to the logical channel group as the number of available tokens in the token bucket corresponding to the logical channel group; and then, performing resource allocation on the logical channel group according to the minimum value between the number of available tokens in the token bucket corresponding to the logical channel group and the data amount of the actual resource to be allocated of the current logical channel.

Detailed Description

The embodiment of the invention is applied to an application scene of MDBV data transmission in a 5G NR system, and for the 5G NR system, a core network can configure QoS Profile for each Flow. And the RAN performs QoS management for each Flow based on the QoS Profile configured by the core network. One parameter in QoS profile is 5QI, and MDBV is one parameter contained in 5 QI. In the embodiment of the invention, the terminal firstly determines the MDBV corresponding to the object and the token bucket used for MDBV control, and performs resource allocation for the object according to the determined MDBV and the token bucket used for MDBV control. In the embodiment of the invention, the resources for data transmission are distributed according to the token bucket for MDBV control, so that the data volume sent by each QoS Flow is ensured not to exceed the MDBV limit, and the delay sensitive service is prevented from preempting the resources of other services when the system load is heavier.

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, 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 invention.

As shown in fig. 1, an embodiment of the present invention provides a system for resource allocation, where the system includes: a terminal 100 and a network side device 101.

A terminal 100, configured to determine an MDBV corresponding to a logical channel and a token bucket for MDBV control; and performing resource allocation on the logical channel according to the determined MDBV and the token bucket for MDBV control.

The network side device 101 is mainly used for determining an MDBV corresponding to the resource allocation object and a token bucket for controlling the MDBV; performing resource allocation on the resource allocation object according to the determined MDBV and the token bucket for MDBV control; if uplink resource allocation is carried out, the resource allocation object is a logical channel group; and if the downlink resource allocation is carried out, the resource allocation object is a logical channel.

In the embodiment of the invention, the terminal and the network side equipment firstly determine the MDBV corresponding to the object and the token bucket used for controlling the MDBV, and carry out resource allocation on the object according to the determined MDBV and the token bucket used for controlling the MDBV. In the embodiment of the invention, the resources for data transmission are distributed according to the token bucket for MDBV control, so that the data volume sent by each QoS Flow is ensured not to exceed the MDBV limit, and the delay sensitive service is prevented from preempting the resources of other services when the system load is heavier.

The following describes a system for allocating resources in detail by taking downlink resources as an example.

Method one, carry on the resource allocation to the downlink resource

When the downlink resources are allocated, after the network side equipment determines that the establishment of the logical channel is completed and/or the network side equipment determines that the resource allocation needs to be performed based on the MDBV according to the system load, the network side equipment determines the MDBV corresponding to the logical channel and a token bucket for controlling the MDBV.

When the network side device determines the MDBV corresponding to the logical channel in the MAC layer, because several different situations exist in the mapping relationship between the Flow and the logical channel, the MDBV corresponding to the logical channel determined by the network side device may also be different, and the following description is made for different situations:

in the first case: if Flow and logical channels use 1:1, the network side device takes the MDBV corresponding to the Flow as the MDBV corresponding to the logic channel;

for example, Flow and logical channel use 1: and 1, mapping according to the ratio, wherein only 1 logic channel is mapped with only 1 Flow, and the MDBV of the Flow is taken as the MDBV corresponding to the logic channel.

In the second case: if the Flow and the logic channel adopt M:1 ratio mapping, the network side equipment obtains the sum of MDBV corresponding to the Flow mapped to the logic channel according to the mapping relation of the Flow and the logic channel and takes the sum as the MDBV corresponding to the logic channel, wherein M is a positive integer.

For example, the Flow and the logical channel adopt 6:1 ratio mapping, at this time, 6 flows are mapped to the same logical channel, the network side device adds the MDBV corresponding to the 6 flows, and the sum of the MDBV is used as the MDBV corresponding to the logical channel.

In the third case: and if the Flow and the logic channel adopt M:1 ratio mapping, the network side equipment takes the sum of MDBVs corresponding to the flows actually mapped to the logic channel in the mapping relation of the Flow and the logic channel as the MDBVs corresponding to the logic channel, wherein M is a positive integer.

For example, the flows and the logical channels adopt 6:1 ratio mapping, and M flows should be mapped to the same logical channel at this time according to an actual mapping rule, but only 3 flows are actually mapped to the same logical channel, and at this time, the network side device adds up the MDBVs corresponding to the 3 flows, and takes the sum of the MDBVs as the MDBV corresponding to the logical channel.

Since the network side device determines the MDBV corresponding to the logical channel at the root of the MAC layer, but the MAC layer does not know the mapping relationship between the Flow and the logical channel and the MDBV corresponding to the logical channel, the network side device may determine the MDBV corresponding to the logical channel at the MAC layer only by notifying the MAC layer in advance, and specifically, may notify the MAC layer in the following manner.

(1) The network side equipment informs the mapping relation between the Flow and the logical channel of the MAC layer through the SDAP or RRC layer;

and when the network side equipment informs the mapping relation between the Flow and the logical channel of the MAC layer, the Flow is expressed by QFI, and the MAC layer determines the MDBV corresponding to each Flow according to the corresponding relation between the QFI and the 5QI identification stored in the MAC layer and the corresponding relation between the 5QI and the MDBV. And finally, adding the MDBVs corresponding to the flows mapped to the logic channels to obtain the MDBV corresponding to the logic channels.

(2) And the network side equipment informs the mapping relation between the Flow and the logical channel of the MAC layer and the MDBV corresponding to the QFI through the SDAP or the RRC layer.

After the mapping relation between the Flow and the logic channel and the MDBV corresponding to the QFI are known by the MAC layer, the Flow mapped to the logic channel can be known by the network side equipment according to the mapping relation between the Flow and the logic channel, the MDBV corresponding to each Flow is found according to the MDBV corresponding to the QFI, and finally the MDBVs corresponding to the flows mapped to the logic channel are added to obtain the MDBV corresponding to the logic channel.

(3) And the network side equipment informs the MDBV corresponding to the logic channel of the MAC layer through the SDAP or RRC layer.

In this case, the network side device may directly determine the MDBV corresponding to the logical channel according to the notification of the SDAP or the RRC layer.

(4) And the network side equipment informs the MAC layer of the Flow actually mapped to the logical channel through the SDAP layer.

The network side device informs the MAC layer of the Flow actually mapped to the logical channel through the SDAP, the Flow is represented by QFI, and the MAC layer determines the MDBV corresponding to each Flow according to the corresponding relation of the QFI and the 5QI identification stored in the MAC layer and the corresponding relation of the 5QI and the MDBV. And finally, adding the MDBVs corresponding to the flows mapped to the logic channels to obtain the MDBV corresponding to the logic channels.

(5) And the network side equipment informs the MAC layer of the MDBV corresponding to the Flow and the QFI actually mapped to the logic channel through the SDAP layer.

And after the MAC layer knows the Flow actually mapped to the logic channel and the MDBV corresponding to the QFI, the network side equipment finds out the MDBV corresponding to each Flow actually mapped to the logic channel according to the MDBV corresponding to the QFI, and finally adds up the MDBVs corresponding to the flows actually mapped to the logic channel to obtain the MDBV corresponding to the logic channel.

(6) And the network side equipment informs the MDBV corresponding to the logic channel of the MAC layer through the SDAP layer.

The network side equipment can directly determine the MDBV corresponding to the logic channel according to the notification of the SDAP layer.

Here, it should be noted that: one of the above modes may be adopted when the MAC layer is notified, or a plurality of modes may be used simultaneously.

Correspondingly, after the network side equipment determines that the MDBV corresponding to the logical channel is used, the network side equipment takes the MDBV corresponding to the logical channel as the size of a token bucket used for MDBV control by the logical channel, and determines the number M of tokens which are actually used in a time period (N-PDB, N) of the token bucket used for MDBV control by the logical channel, wherein N is a scheduling time, and PDB is a data packet delay budget corresponding to the logical channel.

In a specific implementation, an optional implementation is: and the network side equipment takes the difference between the MDBV corresponding to the logical channel and the number of the tokens which are actually used in the token bucket for MDBV control of the current logical channel as the number of the available tokens in the token bucket for MDBV control of the logical channel.

Correspondingly, after the number of the available tokens in the token bucket used for MDBV control as the logical channel is obtained, the network side equipment allocates resources for the logical channel according to the minimum value between the number of the available tokens in the token bucket used for MDBV control by the logical channel and the data amount of the actual resources to be allocated by the current logical channel.

The PDB determination mode is as follows:

the terminal determines 5 QIs corresponding to all flows of all logical channels capable of being mapped or 5 QIs corresponding to all flows actually mapped to the logical channels according to the mapping relation of the logical channels; and finally, determining the maximum PDB from the 5QI corresponding to the Flow as the PDB corresponding to the logic channel.

For example, the network side device first determines that the logical channels that can be mapped to the logical channel group or actually mapped to the logical channel group are logical channels 1, 2, 3, and 4, then the network side device determines 5 QIs corresponding to flows corresponding to the logical channels 1, 2, 3, and 4, and then determines the largest PDB as the PDB corresponding to the logical channel group according to a standardized 5QI table of 3GPP from the determined 5 QIs corresponding to flows.

And after the network side equipment determines the MDBV corresponding to the logical channel and the token bucket used for controlling the MDBV, performing resource allocation on the logical channel according to the determined MDBV and the token bucket used for controlling the MDBV.

For example, if the number of available tokens in the token bucket used by the logical channel for MDBV control is smaller than the data amount required by the logical channel, the network side device preferentially allocates resources for the data that meets the MDBV requirement corresponding to the logical channel, and if there are remaining resources, the network side device allocates resources for the data that does not meet the MDBV requirement corresponding to the logical channel group according to the data amount of the resources that can be allocated by the logical channel.

As shown in fig. 2, an embodiment of the present invention provides a flowchart of a complete method for resource allocation of downlink resources.

Step 200, the network side equipment determines that the establishment of the logical channel is completed and/or the network side equipment determines that resource allocation needs to be carried out based on MDBV according to the system load;

step 201, the network side device determines the MDBV corresponding to the logical channel through the MAC layer;

step 202, the network side device determines the number M of the tokens which are actually used in a token bucket for MDBV control in a time period (N-PDB, N);

step 203, the network side device takes the difference between the MDBV corresponding to the logical channel and the number M of the tokens which are actually used in the time period (N-PDB, N ]) in the token bucket for controlling the MDBV as the number of the available tokens in the token bucket for controlling the MDBV by the logical channel;

and step 204, the network side equipment allocates resources for the logical channels according to the minimum value between the number of available tokens in the token bucket for MDBV control of the logical channels and the data volume of the resources to be actually allocated by the current logical channels.

Second mode, resource allocation is carried out on uplink resources

When the uplink resources are allocated, the network side equipment needs to allocate the uplink resources for different terminals, and when the network side equipment determines that the establishment of the logical channel is completed and/or the network side equipment determines that the resource allocation needs to be performed based on the MDBV according to the system load, the MDBV corresponding to the logical channel group and the token bucket used for controlling the MDBV are determined.

The network side device may determine the MDBV corresponding to the logical channel group in the following centralized manner:

1. and the network side equipment determines the MDBV corresponding to the logic channel according to the mapping relation between the Flow and the logic channel, and takes the sum of the MDBVs corresponding to the logic channels in the same logic channel group as the MDBV corresponding to the logic channel group.

For example, the network side device determines the MDBV corresponding to the logical channels 1, 2, and 3 according to the mapping relationship between the Flow and the logical channel, and the logical channels 1 and 2 are in the same logical channel group 1, and at this time, the network side device takes the sum of the MDBV corresponding to the logical channels 1 and 2 as the MDBV corresponding to the logical channel group 1.

However, because there are several different situations in the mapping relationship between the Flow and the logical channel, the MDBV corresponding to the logical channel determined by the network side device will also be different, and the following description will be made for different situations:

In the second case: if the Flow and the logic channel adopt M:1 ratio mapping, the network side equipment takes the sum of MDBVs corresponding to the Flow which can be mapped to the logic channel as the MDBVs corresponding to the logic channel according to the mapping relation of the Flow and the logic channel; wherein M is a positive integer.

In the third case: if the Flow and the logic channel adopt M:1 ratio mapping, at this time, the network side device will take the sum of the MDBVs corresponding to the Flow actually mapped to the logic channel as the MDBVs corresponding to the logic channel according to the mapping relation of the Flow and the logic channel. Wherein M is a positive integer.

For example, the flows and the logical channels adopt 6:1 ratio mapping, and at this time, 6 flows should be mapped to the same logical channel according to an actual mapping rule, but only 3 flows are actually mapped to the same logical channel, and at this time, the network side device adds up the MDBVs corresponding to the 3 flows, and takes the sum of the MDBVs as the MDBV corresponding to the logical channel.

2. And the network side equipment receives the sum of the MDBVs corresponding to the logical channels reported by the terminal, and takes the sum of the MDBVs corresponding to the reported logical channels as the MDBV corresponding to the logical channel group.

For example, the network side device may receive the sum of the MDBV corresponding to the logical channels 1, 2, and 3 reported by the end, where the logical channels 1, 2, and 3 are in the same logical channel group 1, and at this time, the network side device takes the sum of the MDBV corresponding to the reported logical channels 1, 2, and 3 as the MDBV corresponding to the logical channel group 1.

3. And the network side equipment receives the MDBV corresponding to the logical channel group reported by the terminal, and then takes the MDBV corresponding to the reported logical channel group as the MDBV corresponding to the logical channel group.

For example, the terminal reports the sum of the MDBV corresponding to the logical channels 1, 2, and 3 in the same logical channel group 1 to the network side device, and the network side device takes the reported sum of the MDBV corresponding to the same logical channel group 1 as the MDBV corresponding to the logical channel group 1.

Since the network side device determines the MDBV corresponding to the logical channel group in the MAC layer, the MAC layer does not know the mapping relationship between the Flow and the logical channel and the MDBV corresponding to the logical channel, and thus needs to notify the MAC layer in advance.

In addition, when the uplink resource allocation is performed, the MAC layer does not know the mapping relationship between the logical channel and the logical channel group, and therefore the RRC layer also needs to notify the mapping relationship between the logical channel and the logical channel group of the MAC layer, so that the network side device can determine the MDBV corresponding to the logical channel group in the MAC layer, and specifically, the MAC layer can be notified in the following manner.

And then the MAC layer determines the sum of the MDBVs of all the logical channels mapped to the logical channel group as the MDBV of the logical channel group according to the mapping relation between the logical channels and the logical channel group.

The terminal SDAP and the network side SDAP need information interaction, and the network equipment acquires the Flow information actually mapped to the logic channel by the network side equipment of the terminal side equipment through the SDAP layer.

And then the SDAP of the network side informs the MAC layer of the Flow actually mapped to the logical channel, the Flow is expressed by QFI, and the MAC layer determines the MDBV corresponding to each Flow according to the corresponding relation of the QFI and the 5QI identification stored by the MAC layer and the corresponding relation of the 5QI and the MDBV. And finally, adding the MDBVs corresponding to the flows mapped to the logic channels to obtain the MDBV corresponding to the logic channels.

Then the network side SDAP informs the MAC layer of the Flow actually mapped to the logic channel, after the Flow actually mapped to the logic channel and the MDBV corresponding to the QFI are known by the MAC layer, the network side equipment finds the MDBV corresponding to each Flow actually mapped to the logic channel according to the MDBV corresponding to the QFI, and finally adds the MDBVs corresponding to the flows actually mapped to the logic channel to obtain the MDBV corresponding to the logic channel.

And then the SDAP layer at the network side determines the MDBV corresponding to the logical channel according to the mapping relation between the actual Flow and the logical channel, and the MAC layer can directly determine the MDBV corresponding to the logical channel according to the notification of the SDAP layer.

Here, it should be noted that: the above manner of notifying the MAC layer may be one of the manners, or may be a plurality of manners at the same time.

Correspondingly, after the network side device determines the MDBV corresponding to the logical channel group, the network side device uses the MDBV as the size of the token bucket used for MDBV control by the logical channel group, and determines the number M of the tokens actually used by the token bucket used for MDBV control in a time period (N-PDB, N), wherein N is a scheduling time, and PDB is a data packet delay budget corresponding to the logical channel.

PDB was determined as follows:

and the terminal determines all 5 QIs corresponding to all flows which can be mapped to the logic channel group or all 5 QIs corresponding to all flows which are actually mapped to the logic channel group according to the mapping relation between the flows and the logic channels, and finally determines the largest PDB as the PDB corresponding to the logic channel group according to the 5 QIs corresponding to the flows.

For example, the network side device first determines that the logical channels that can be mapped to the logical channel group or actually mapped to the logical channel group are logical channels 1, 2, 3, and 4, then the network side device determines 5 QIs corresponding to flows corresponding to the logical channels 1, 2, 3, and 4, and then determines the largest PDB as the PDB corresponding to the logical channel group from the determined 5 QIs corresponding to the flows.

And after the network side equipment determines the MDBV corresponding to the logical channel group and the token bucket for controlling the MDBV, performing resource allocation on the logical channel group according to the determined MDBV and the token bucket for controlling the MDBV.

In a specific implementation, an optional implementation is: and the network side equipment takes the difference between the MDBV corresponding to the logical channel group and the number of the tokens which are actually used in the token bucket for MDBV control as the number of the available tokens in the token bucket corresponding to the logical channel group.

For example, the MDBV corresponding to the logical channel group is 200 bits, the number of the tokens actually used in the token bucket for MDBV control is 100 bits, and at this time, the difference between the MDBV and the tokens is 100-100, and the number of the available tokens used in the token bucket for MDBV control by the difference (100 bits) is 100 bits.

After the number of available tokens in a token bucket used for MDBV control as a logical channel group is obtained, if the number of the available tokens of the logical channel group is less than the actual data volume to be transmitted of the logical channel group, the network side equipment preferentially allocates resources for the data meeting the MDBV requirement corresponding to the logical channel group, and if remaining resources exist, the network side equipment allocates resources according to the data which are actually to be transmitted of the logical channel group but do not meet the MDBV requirement corresponding to the logical channel group.

Correspondingly, after the network side device allocates resources for different terminals, the allocated resources are notified to the terminals, and the terminals need to perform resource allocation on the logical channels based on the resources allocated by the network side, so that after the terminals determine that the logical channels are established and/or receive the notification that the resources are required to be allocated based on the MDBV and sent by the network side device, the terminals determine the token bucket for controlling the MDBV and the MDBV corresponding to the logical channels.

When the terminal determines the MDBV corresponding to the logical channel in the MAC layer, the MDBV corresponding to the logical channel determined by the terminal may be different because several different situations may exist in the mapping relationship between the Flow and the logical channel, and the following description is made for different situations:

in the first case: if Flow and logical channels use 1:1, the terminal takes the MDBV corresponding to the Flow as the MDBV corresponding to the logic channel;

for example, the Flow and the logical channel adopt a 1:1 ratio mapping, and at this time, the terminal will use the MDBV of the Flow as the MDBV corresponding to the logical channel.

In the second case: if the Flow and the logic channel adopt M:1 ratio mapping, the terminal takes the sum of MDBVs corresponding to the Flow which can be mapped to the logic channel as the MDBVs corresponding to the logic channel according to the mapping relation of the Flow and the logic channel; wherein M is a positive integer.

For example, the Flow and the logical channel adopt 6:1 ratio mapping, at this time, 6 flows are mapped to the same logical channel, the terminal adds the MDBV corresponding to the 6 flows, and the sum of the MDBV is used as the MDBV corresponding to the logical channel.

In the third case: and if the Flow and the logic channel adopt M:1 ratio mapping, the terminal takes the sum of the MDBVs corresponding to the Flow actually mapped to the logic channel as the MDBVs corresponding to the logic channel according to the mapping relation of the Flow and the logic channel, wherein M is a positive integer.

For example, the flows and the logical channels adopt 6:1 ratio mapping, and at this time, 6 flows should be mapped to the same logical channel according to an actual mapping rule, but actually, only 3 flows are mapped to the same logical channel, and at this time, the MDBV corresponding to the 3 flows are added, and the sum of the MDBV is taken as the MDBV corresponding to the logical channel.

Since the terminal determines the MDBV corresponding to the logical channel in the MAC layer, but the MAC layer does not know the MDBV corresponding to the logical channel and the mapping relationship between the Flow and the logical channel, an inter-layer interaction mechanism needs to be introduced to notify the MAC layer logic, and the terminal can determine the MDBV corresponding to the logical channel in the MAC layer, and specifically, the following manner can be adopted to notify the MAC layer.

(1) And the terminal informs the media access control MAC layer of the mapping relation between the Flow and the logical channel through a service data adaptation layer SDAP or a radio resource control RRC layer.

And the Flow is expressed by QFI when the SDAP or RRC of the terminal informs the mapping relation between the Flow and the logical channel of the MAC layer, and the MAC layer determines the MDBV corresponding to each Flow according to the corresponding relation between the QFI and the 5QI identification stored in the MAC layer and the corresponding relation between the 5QI and the MDBV. And finally, adding the MDBVs corresponding to the flows mapped to the logic channels to obtain the MDBV corresponding to the logic channels.

(2) And the terminal informs the mapping relation between the Flow and the logic channel of the MAC layer and the MDBV corresponding to the QFI through the SDAP or the RRC layer.

After the mapping relation between the Flow and the logic channel and the MDBV corresponding to the QFI are known by the MAC layer, the Flow mapped to the logic channel can be known by the terminal according to the mapping relation between the Flow and the logic channel, the MDBV corresponding to each Flow is found according to the MDBV corresponding to the QFI, and finally the MDBVs corresponding to the flows mapped to the logic channel are added to obtain the MDBV corresponding to the logic channel.

(3) And the terminal informs the MDBV corresponding to the logic channel of the MAC layer through the SDAP or the RRC layer.

The MAC can obtain the MDBV corresponding to the logical channel directly according to the notification. The MDBV is a sum of MDBV corresponding to flows that can be mapped to the logical channel.

(4) And the terminal informs the MAC layer of the Flow actually mapped to the logical channel through the SDAP layer.

And after the MAC layer knows the Flow actually mapped to the logic channel and the MDBV corresponding to the QFI, finding out the MDBV corresponding to each Flow actually mapped to the logic channel according to the MDBV corresponding to the QFI, and finally adding the MDBVs corresponding to the flows actually mapped to the logic channel to obtain the MDBV corresponding to the logic channel.

(5) And the terminal informs the MAC layer of the MDBV corresponding to the Flow and QFI actually mapped to the logic channel through the SDAP layer.

(6) And the terminal informs the MDBV corresponding to the logic channel of the MAC layer through the SDAP layer.

The MAC layer can obtain the MDBV corresponding to the logical channel directly according to the notification. The MDBV is a sum of MDBV corresponding to flows actually mapped to the logical channel.

Here, it should be noted that: the above two manners of notifying the MAC layer may be used either alone or in combination.

Correspondingly, after the terminal determines the MDBV corresponding to the logical channel, the terminal takes the MDBV corresponding to the logical channel group as the size of the token bucket used for MDBV control by the logical channel group, and determines the number of the tokens which are actually used by the token bucket used for MDBV control in a time period (N-PDB, N), wherein N is the scheduling time, and PDB is the data packet delay budget corresponding to the logical channel.

After the terminal determines the MDBV and the token bucket for MDBV control corresponding to the logical channel group, the terminal performs resource allocation for the logical channel group according to the determined MDBV and the token bucket for MDBV control, and an optional implementation manner is as follows:

step 1: the terminal firstly sorts the logic channels with available PBR tokens and data transmission requirements according to the descending order of the priority of the logic channels, then the terminal carries out first round of resource allocation on each logic channel based on the PBR in sequence, meanwhile, the number of tokens in a PBR token bucket corresponding to each logic channel is updated, and after the PBR-based resource allocation is completed on the logic channel with MDBV requirements, the number of available tokens in the MDBV token bucket corresponding to the logic channel is updated.

The number of the available tokens in the token bucket corresponding to the logical channel is the difference between the MDBV and the number of the tokens actually used by the logical channel in the token bucket corresponding to the current moment;

for example, the MDBV corresponding to the logical channel group is 200 bits, the number of tokens that have been actually used in the token bucket for MDBV control is 100 bits, and at this time, the difference between the MDBV and the token bucket is 200 bits and 100 bits, so that the number of tokens that can be used in the token bucket corresponding to the logical channel group is 100 bits.

Step 2: after the terminal determines that the remaining allocable resources exist, performing a second round of resource allocation on all the logical channels with the data transmission requirements according to the descending order of the logical channel priorities, specifically:

for the logic channel with the MDBV requirement, in the second round of resource allocation process, the logic channel allows the data amount of the allocated resources to measure the logic channel for the smaller value of the number of the usable tokens in the token bucket controlled by the MDBV and the data amount of the resources to be allocated currently by the logic channel, and the resources are allocated to the logic channel;

and if the logical channel needing to be allocated currently is the logical channel without the MDBV requirement, the terminal allocates the resources to the logical channel according to the data volume of the resources to be allocated currently of the logical channel.

For example, the terminal determines a logical channel having an MDBV requirement, and at this time, the number of available tokens in the current token bucket corresponding to the logical channel is 40 bits, the data volume of the resource that can be allocated in the current token bucket of the logical channel is 60 bits, and at this time, the terminal takes the smaller value (40 bits) between the two to allocate the resource to the logical channel.

If the logical channel which the terminal needs to allocate currently is the logical channel without the MDBV requirement, the terminal has two modes to allocate the resource.

One way is as follows: the terminal allocates resources to the logical channels according to the data volume of the resources to be allocated currently of the logical channels:

for example, the data amount of the current resource to be allocated of the logical channel is 600 bits, and the terminal performs resource allocation according to the 600 bits at this time.

The other mode is as follows: and if the logical channel needing to be allocated is the logical channel without the MDBV requirement and containing the GBR service, the terminal allocates the resources to the logical channel according to the data volume of the resources to be allocated currently by the logical channel.

For example, the data size of the current resource to be allocated of the logical channel is 600 bits, and the current logical channel to be allocated is a logical channel including GBR traffic, and at this time, the terminal performs resource allocation only on the logical channel according to the 600 bits.

And step 3: after the second round of allocation, if the terminal determines that the remaining resources exist, resource allocation is performed on the remaining data to be transmitted according to the descending order of priority of all the logical channels with the data transmission requirements until the resources are exhausted or the resources are allocated to the data to be transmitted of all the logical channels.

And after the allocation is finished, the terminal judges whether the residual resources exist or not, and if the residual resources exist, the terminal performs resource allocation on each logic channel according to the residual resources and the priority sequence of the logic channel.

The PDB determination mode is as follows:

and the terminal determines 5 QIs corresponding to all flows which can be mapped to the logic channel group or 5 QIs corresponding to all flows which are actually mapped to the logic channel group according to the mapping relation between the flows and the logic channels, and finally determines the largest PDB as the PDB corresponding to the logic channel group according to the 5 QIs corresponding to the flows.

For example, the network side device first determines that a logical channel that can be mapped or a logical channel that is actually mapped is logical channels 1, 2, 3, and 4, then determines a 5QI corresponding to a Flow corresponding to the logical channels 1, 2, 3, and 4 from a field, and then determines the largest PDB as the PDB corresponding to the logical channel from the determined 5QI corresponding to the Flow.

As shown in fig. 3, an embodiment of the present invention provides a flowchart of a complete method for allocating uplink resources at a terminal side.

Step 300, the terminal needs to determine that the establishment of the logical channel is completed and/or receives a notification that the resource allocation needs to be performed based on MDBV and sent by the network side equipment;

step 301, the terminal determines the MDBV corresponding to the logic channel through the MAC layer;

step 302, the terminal network side device determines the number of tokens which are actually used in a token bucket for MDBV control in a time period (N-PDB, N);

step 303, the terminal sorts the logical channels with available PBR tokens and data transmission requirements according to the descending order of the priority of the logical channels;

step 304, the terminal sequentially performs a first round of resource allocation on each logical channel based on the PBR, simultaneously updates the number of tokens in a PBR token bucket corresponding to each logical channel group, and updates the number of available tokens in the token bucket for MDBV control corresponding to each logical channel group;

305, after the terminal completes resource allocation based on PBR for the logic channel with the MDBV requirement, updating the number of available tokens in a token bucket used for MDBV control by the logic channel;

step 306, after the terminal determines that there are remaining allocable resources, it is determined whether the current logical channel to be allocated has a logical channel required by MDBV, if yes, step 307 is executed; otherwise, go to step 308;

307, the terminal takes the smaller value of the number of available tokens in a token bucket used for MDBV control by the logical channel and the data size of the current resource to be allocated by the logical channel, and allocates the resource to the logical channel;

308, the terminal allocates resources to the logical channel according to the data volume of the current resources to be allocated to the logical channel, or the logical channel which is required to be allocated before is a logical channel which has no MDBV requirement and contains GBR service, and allocates resources to the logical channel according to the data volume of the current resources to be allocated to the logical channel;

step 309, the terminal determines that there are remaining resources, and performs resource allocation on the remaining data to be transmitted according to the descending order of priority of all the logical channels having the data transmission requirement.

As shown in fig. 4, an embodiment of the present invention provides a flowchart of a complete method for resource allocation of uplink resources to a network device.

Step 400, the network side device determines that the establishment of the logical channel is completed and/or the network side device determines that resource allocation needs to be performed based on the MDBV according to the system load, and notifies the terminal that the resource allocation needs to be performed based on the MDBV according to the system load;

step 401, the network side device determines the MDBV corresponding to the logical channel group through the MAC layer;

step 402, the network side device determines the number of tokens which are actually used in a token bucket for MDBV control in a time period (N-PDB, N) of a logical channel;

step 403, the network side device takes the difference between the MDBV corresponding to the logical channel group and the number M of the tokens that have been actually used in the time period (N-PDB, N ") in the token bucket for MDBV control as the number of available tokens in the token bucket for MDBV control of the logical channel group;

step 404, the network side device preferentially allocates resources for the data meeting the MDBV requirement corresponding to the logical channel group;

step 405, the network side device judges that the residual resources exist, if yes, step 406 is executed, otherwise, the resource allocation is ended;

step 406, the network side device allocates resources according to the data to be actually transmitted in the logical channel group but not meeting the MDBV requirement corresponding to the logical channel group;

step 407, the network side device ends the resource allocation.
