Description

Resource allocation method, device, communication equipment and storage medium

Technical Field

The present disclosure relates to, but not limited to, the field of wireless communications technologies, and in particular, to a method, an apparatus, a communication device, and a storage medium for resource allocation.

Background

In a long term evolution (Long Term Evolution, LTE) system of a fourth generation mobile communication technology (4G), in order to support internet of things (Internet of Thing, ioT) services, two major technologies of machine-type communication (Machine Type Communication, MTC) and narrowband internet of things (Narrow band Internet of thing, NB-IoT) are proposed; the two major techniques are mainly directed to relatively low rate, high latency, etc. scenarios. For example, NB-IoT devices can currently only support rates of up to a few hundred kbps; as another example, MTC devices currently only support a maximum of a few Mbps. Meanwhile, with the continuous development of the business of the Internet of things, such as popularization of the business of video monitoring, intelligent home, wearable equipment, industrial sensor monitoring and the like; devices in both technologies typically require rates of tens or hundreds of Mbps and require relatively high latency. Thus, the MTC in the 4G LET and the devices in the NB-IoT cannot meet the requirements of the continuously developing internet of things service.

In the related art, for medium-high speed applications, a new type of User Equipment (UE) is introduced; the new UE may be a reduced capability (Reduced capability, redCap) UE. As technology evolves, the applicable bandwidth for RedCap is further reduced, i.e. further enhanced, illustratively from 20MHz to 5MHz.

In the New air interface (NR, new Radio) system, the maximum resource that can be allocated by the UE may be the same as the size of the partial Bandwidth (BWP) allocated to the UE. However, for the reduced RedCap UE or the enhanced RedCap UE, if the resource granularity is still determined according to the BWP allocated to the UE to allocate the resources, the resource allocation of the UE is remorsed, which brings great limitation and resource waste.

Disclosure of Invention

The embodiment of the disclosure provides a resource allocation method, a resource allocation device, communication equipment and a storage medium.

According to a first aspect of embodiments of the present disclosure, there is provided a resource allocation method, performed by a UE, comprising:

determining a resource allocation granularity based on the first information, wherein the resource allocation granularity is a minimum allocation unit for performing resource allocation for the UE; wherein the first information includes at least one of: bandwidth capability information of the UE and configuration information indicating a granularity of resource allocation.

According to a second aspect of embodiments of the present disclosure, there is provided a resource allocation method performed by a network device, comprising:

and sending configuration information, wherein the configuration information is used for determining resource allocation granularity by the UE, and the resource allocation granularity is the minimum allocation unit for carrying out resource allocation for the UE.

According to a third aspect of embodiments of the present disclosure, there is provided a resource allocation apparatus, applied to a UE, including:

a first processing module configured to determine a resource allocation granularity based on the first information, wherein the resource allocation granularity is a minimum allocation unit for resource allocation for the UE; wherein the first information includes at least one of: bandwidth capability information of the UE and configuration information indicating a granularity of resource allocation.

According to a fourth aspect of embodiments of the present disclosure, there is provided a resource allocation apparatus, applied to a network device, including:

and the second sending module is configured to send configuration information, wherein the configuration information is used for determining resource allocation granularity by the UE, and the resource allocation granularity is the minimum allocation unit for resource allocation of the UE.

According to a fifth aspect of the present disclosure, there is provided a communication device, comprising:

A processor;

a memory for storing processor-executable instructions;

wherein the processor is configured to: when used to execute executable instructions, implement the resource allocation method of any embodiment of the present disclosure.

According to a sixth aspect of the present disclosure, there is provided a computer storage medium storing a computer executable program which when executed by a processor implements the resource allocation method of any embodiment of the present disclosure.

The technical scheme provided by the embodiment of the disclosure can comprise the following beneficial effects:

in the embodiment of the disclosure, a resource allocation granularity may be determined by the UE based on the first information, where the resource allocation granularity is a minimum allocation unit for performing resource allocation for the UE; wherein the first information includes at least one of: bandwidth capability information of the UE and configuration information related to indication of resource allocation granularity; in this way, the UE can be configured with an appropriate resource allocation granularity and flexibly allocated with the resource allocation granularity.

For example, when the UE determines the resource allocation granularity based on bandwidth capability information of the UE, the bandwidth capability information includes that the maximum transmission bandwidth of the UE is smaller than the BWP allocated to the UE, and the resource allocation granularity determined by the UE may be smaller than the resource allocation granularity determined based on the BWP allocated to the UE. On one hand, the resource waste caused by relatively larger allocation granularity of the maximum transmission bandwidth allocated to the relatively smaller UE is reduced; on the other hand, the flexibility of resource allocation for the data channel to the UE can be improved due to the fact that the smaller resource allocation granularity can be determined, so that more RBG combinations are provided for resource allocation to the UE.

For another example, when the UE determines the resource allocation granularity based on the configuration information, the UE may directly determine the resource allocation granularity suitable for the UE based on an indication of the network device or the like, or may improve flexibility of the resource allocation granularity of the UE, so as to improve flexibility of resource allocation for the UE for the data channel.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of embodiments of the disclosure.

In order to better understand the technical solution described in any embodiment of the present disclosure, first, a part of a resource allocation manner in the related art will be described.

In one embodiment, two resource allocation manners are supported in the new air interface: type0 resource allocation scheme and type 1 resource allocation scheme.

Type0 resource allocation mode: the method is a mode of discontinuous allocation of frequency domain resources, and is relatively flexible: a bitmap (bitmap) is used to indicate frequency domain resources for allocation to UEs, 1 indicating allocation and 0 indicating non-allocation. Each bit represents a resource block group (RBG, resource Block Group), the size of the RBG being related to two factors. Referring to table 1, one is the Size of the current BWP, and the other is whether the parameter rbg-Size is Configuration 1 (Configuration 1) or Configuration 2 (Configuration 2). Index of RBG is counted from low frequency (low frequency) to high frequency (high frequency) of BWP in the frequency domain.

Bandwidth portion size (RB)	Configuration 1	Configuration 2
1–36	2	4
37–72	4	8
73–144	8	16
145–275	16	16

TABLE 1

Type1 resource allocation mode: a method of continuously allocating frequency domain resources is a method of informing a UE of a start position rb_start of an allocated RB and how many consecutive RBs, i.e., l_rbs, are allocated using a resource indication value (RIV, resource Indication Value). And the resource allocation indication is performed by jointly encoding S and L to obtain the RIV.

It will be appreciated that each of the elements in table 1 and the tables (e.g., tables 2 to 7) in the subsequent embodiments described above are independent, and these elements are illustratively listed in the same table, but do not represent that all elements in the table must exist simultaneously as shown in the table. Wherein the value of each element in each table is independent of the value of any other element in each table. It will be appreciated by those skilled in the art that the values of each element in each table are independent embodiments.

As shown in fig. 2, an embodiment of the present disclosure provides a resource allocation method, which is performed by a UE, including:

step S21: determining a resource allocation granularity based on the first information, wherein the resource allocation granularity is a minimum allocation unit for performing resource allocation for the UE; wherein the first information includes at least one of: bandwidth capability information of the UE and configuration information indicating a granularity of resource allocation.

The first information includes predetermined information. The predetermined information includes: bandwidth capability information and/or configuration information of the UE.

Here, the UE may be various mobile terminals or fixed terminals. For example, the UE may be, but is not limited to being, a cell phone, a computer, a server, a wearable device, a game control platform, or a multimedia device, etc. For example, the UE may be a RedCAP UE or a 5G NR-lite UE, etc.

Here, the resource allocation granularity may be: a minimum allocation unit for resource allocation for a data channel or a transport channel supported by the UE.

In one embodiment, the Resource allocation granularity may be a granularity including a predetermined number of Resource Blocks (RBs). Here, the predetermined number is an integer greater than 0.

In one embodiment, the predetermined number of RBs may be one resource block group (Resource Block Group, RBG).

Here, the bandwidth capability information includes at least a maximum transmission bandwidth supported by the UE.

In one embodiment, the bandwidth capability information includes at least a maximum transmission bandwidth supported by the UE for data channel transmission.

Here, the maximum transmission bandwidth of the UE is smaller than a partial Bandwidth (BWP) allocated to the UE. Since the maximum transmission bandwidth of the UE is smaller than the BWP allocated to the UE, the embodiments of the present disclosure may be smaller with respect to the conventional resource allocation granularity determined based on the BWP allocated to the UE. For example, for conventional BWP based on allocation to the UE (the BWP including 73 to 144 if included), the determined resource allocation granularity is a resource allocation granularity including 8 RBs; if the maximum transmission bandwidth of the UE includes 37 to 72 RBs, the resource allocation granularity determined according to the maximum transmission bandwidth of the UE may be a resource allocation granularity including 4 RBs.

In some embodiments, the step S21 includes one of:

determining a resource allocation granularity based on bandwidth capability information of the UE;

determining a resource allocation granularity based on configuration information related to the indication resource allocation granularity;

the resource allocation granularity is determined based on the bandwidth capability information of the UE and configuration information related to the indication resource allocation granularity.

The embodiment of the disclosure provides a resource allocation method, which is executed by UE and comprises at least one of the following steps:

In one embodiment, determining the resource allocation granularity based on the bandwidth capability information of the UE includes: the resource allocation granularity is determined based on the maximum transmission bandwidth of the UE.

In one embodiment, determining the resource allocation granularity based on the bandwidth capability information of the UE and configuration information related to the indication of the resource allocation granularity comprises: the resource allocation granularity is determined based on the maximum transmission bandwidth of the UE and configuration information related to the indication resource allocation granularity.

Here, the configuration information includes at least one of:

configuration information indicating a resource allocation granularity;

configuration information indicating a resource allocation granularity configuration mode.

For example, when the UE determines the resource allocation granularity based on the bandwidth capability information of the UE, the bandwidth capability information includes that the maximum transmission bandwidth of the UE is smaller than the BWP allocated to the UE, and at this time, the determined resource allocation granularity of the UE may be smaller relative to the determined resource allocation granularity based on the BWP allocated to the UE, so that on one hand, the waste of resources due to the relatively larger allocation granularity of the maximum transmission bandwidth allocated to the relatively smaller UE is reduced; on the other hand, the flexibility of resource allocation for the data channel to the UE can be improved due to the fact that the smaller resource allocation granularity can be determined, so that more RBG combinations are provided for resource allocation to the UE.

It should be noted that, as those skilled in the art may understand, the methods provided in the embodiments of the present disclosure may be performed alone or together with some methods in the embodiments of the present disclosure or some methods in the related art.

The embodiment of the disclosure provides a resource allocation method, which is executed by a UE and comprises the following steps: the resource allocation granularity is determined based on the maximum transmission bandwidth of the UE.

The candidate frequency range may be a partial Bandwidth (BWP), for example, one candidate frequency range may be a BWP range including 1 to 36 RBs.

The first mapping relationship includes: at least one candidate frequency range is predefined, and the resource allocation granularity corresponding to the candidate frequency range is predefined.

Here, the size of the maximum transmission bandwidth of the UE is positively correlated with the size of the resource allocation granularity.

As shown in fig. 3, an embodiment of the present disclosure provides a resource allocation method, which is performed by a UE, including:

step S31: determining a resource allocation granularity based on the maximum transmission bandwidth of the UE and the first mapping relation; the first mapping relation comprises the following steps: and mapping relation between the candidate frequency range where the maximum transmission bandwidth is located and the resource allocation granularity.

In some embodiments of the present disclosure, the maximum transmission bandwidth may be the maximum transmission bandwidth in the above embodiments; the resource allocation granularity may be the resource allocation granularity in step S21.

Here, the candidate frequency range may be one or more. In some embodiments of the present disclosure, the plurality may be two or more.

the determining the resource allocation granularity based on the maximum transmission bandwidth of the UE and the first mapping relation includes: and determining the resource allocation granularity corresponding to the candidate frequency range as the resource allocation granularity of the UE based on the candidate frequency range of the maximum transmission bandwidth of the UE.

In one embodiment, the first mapping relationship includes at least: a first resource allocation granularity of the first candidate frequency range corresponding to the first candidate frequency range, and a second resource allocation granularity of the second candidate frequency range corresponding to the second candidate frequency range; wherein the first resource allocation granularity comprises a first predetermined number RB; the second resource allocation granularity comprises a second predetermined number RB; wherein the maximum value of the first candidate frequency range is less than or equal to the minimum value of the second frequency range; the first predetermined number is less than the second predetermined number;

when the maximum transmission bandwidth is in the first candidate frequency range, determining that the resource allocation granularity is the first resource allocation granularity;

and when the maximum transmission bandwidth is in the second candidate frequency range, determining the resource allocation granularity as the second resource allocation granularity.

Here, the first candidate frequency range may be a first BWP, and the second candidate frequency range is a second BWP.

Illustratively, the first candidate frequency range includes 1 to 36 RBs and the second candidate frequency range includes 37 to 72 RBs; the first predetermined number is 2, and the second predetermined number is 4; the first resource allocation granularity corresponding to the first candidate frequency range is the resource allocation granularity comprising 2 RBs; the second resource allocation granularity corresponding to the second candidate frequency range is a resource allocation granularity including 4 RBs. Exemplary as shown in table 2, if the maximum transmission bandwidth of the UE is within the first candidate frequency range including 1 to 36 RBs, the resource allocation granularity is the first resource allocation granularity including 2 RBs; if the maximum transmission bandwidth of the UE is within a second candidate frequency range comprising 37 to 72 RBs, the resource allocation granularity is a second resource allocation granularity comprising 4 RBs.

wherein the maximum value of the first predetermined range is less than or equal to the minimum value of the second predetermined range; the first predetermined number is less than the second predetermined number.

Thus, in the embodiment of the present disclosure, according to the maximum transmission bandwidth of the UE and the first mapping relationship, an appropriate resource allocation granularity of the UE under different maximum transmission bandwidths may be determined; this may reduce resource waste on the one hand and may increase flexibility in resource allocation to the data channel of the UE based on the relatively smaller resource allocation granularity, as opposed to determining a relatively larger resource allocation granularity based on the BWP allocated to the UE.

As such, when the UE receives the configuration information, it may be determined that the resource allocation granularity of the UE includes 2 RBs based on the indication information included in the configuration information.
