Description

A method for determining the size of a resource allocation indication field, terminal equipment, and network equipment

technical field

The present invention relates to the technical field of communication, in particular to the technical field of resource indication.

Background technique

In the NR (New Radio, new air interface) wireless access system, both uplink transmission and downlink transmission support two types of frequency domain resource allocation: Type 0 frequency domain resource allocation and Type 1 frequency domain resource allocation. The network side configures the frequency domain resource allocation type used by the terminal device through high-level parameters (such as: resourceAllocation), such as: Type 0 frequency domain resource allocation, Type 1 frequency domain resource allocation, or dynamic switching. When configured as dynamic switching, the network side indicates the type of frequency domain resource assignment used by the terminal device through FDRA (Frequency domain resource assignment, frequency domain resource assignment indication field) in DCI (Downlink Control Information, downlink control information).

If the BWP (Bandwidth Part, bandwidth part) indicator field is not configured in the DCI used for scheduling, or the terminal device does not support DCI-based BWP changes, then the RB (Resource Block, resource block) index corresponding to the frequency domain resource allocation type is in Determined in the activated BWP corresponding to the terminal device. If the terminal device supports DCI-based BWP change, and the DCI used for scheduling is configured with a BWP indicator field, then the resource block RB index corresponding to the frequency domain resource allocation type is determined based on the BWP indicated by the BWP indicator field in the DCI. Therefore, the terminal device needs to first determine the BWP through PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) detection, and then determine the frequency domain resource allocation in the BWP.

The NR system supports terminal devices to perform PDCCH blind detection in SSS (Search Space Sets, search space sets) configured on the network side. The reason why it is called "blind detection" is that the terminal device does not know information such as the format of the DCI before detecting the DCI carried by the PDCCH. Therefore, the terminal device needs to use some fixed DCI size (DCI size) to perform blind detection on the candidate PDCCH in the search space set. In order to reduce the complexity of blind detection of PDCCH by terminal equipment, NR stipulates that after completing the DCI size alignment (DCI size alignment) step defined by the protocol, terminal equipment does not expect the total DCI size to be greater than 4, and C-RNTI (Cell-Radio Network Temporary Identifier, cell wireless network temporary identifier) The total DCI size scrambled is greater than 3.

Since the terminal device only tries to use some fixed DCI sizes to detect the PDCCH, it is necessary for the terminal device to know the DCI sizes of different DCI formats before PDCCH blind detection. That is, before the PDCCH blind detection, the terminal device needs to know the number of bits contained in each information field included in the DCI, such as the FDRA field (Frequency domain resource assignment, frequency domain resource assignment) indication field.

The following embodiments of this application will explain in detail how the terminal device determines the channel resources during the process of scheduling channels of one or more serving cells and/or serving cell groups by one DCI (Downlink Control Information, downlink control information) , further, how does the terminal device determine the number of bits required by the resource allocation indication field during blind detection of the PDCCH. Especially in the case of scheduling channels of multiple serving cells and/or serving cell groups, since the number of scheduled multiple serving cells and/or serving cell groups is uncertain, and the size of the activated BWP on different serving cells ( That is, the number of physical resource blocks (PRBs) included in the activated BWP or the size of the activated BWP group are also different. Therefore, when one DCI schedules the channels of multiple serving cells and/or serving cell groups, how to determine or use the resource allocation indication field (including the frequency domain resource allocation indication field and the time domain resource allocation indication field) in the DCI is an urgent problem to be solved. The problem.

In the following embodiments of this application, the FDRA (Frequency domain resource assignment, frequency domain resource assignment) indication field in DCI is used as an example to illustrate that in the case of one or more serving cells and/or serving cell groups being scheduled by one DCI, How does the terminal device determine the size of the FDRA domain in the DCI, but the method of the present application and its equipment are not limited to determining the size of the FDRA domain, and the indication domains related to the BWP size and high-level configuration parameters in the DCI, such as TDRA (Time domain resource assignment, time Domain Resource Allocation) indicates that domains etc. are applicable. The frequency domain resource or the frequency domain resource allocation indication field in the following description of the present application can be understood as a specific example of the resource or the resource allocation indication field.

It should be noted that the Type 0 frequency domain resource allocation type supported by NR has a resource allocation granularity of RBG (Resource Block Group, resource block group), and RBG is a combination of a series of continuous virtual RB (Resource Block, resource block) , the number of virtual RBs included in each RBG is determined according to the size of the BWP and the RRC configuration parameter rbg-Size. The Type 1 frequency domain resource allocation type supported by NR can indicate a series of continuous virtual RBs to the terminal, and a RIV (resource indication value, resource indication value) is used to perform the allocation on the allocated starting RB (RBstart) and the number of RBs (LRBs) joint encoding.

When the terminal device performs PDCCH blind detection, it needs to know the number of bits contained in each information field contained in the DCI. Taking the FDRA field as an example, the determination method of the number of bits is as follows:

If only the type 0 frequency domain resource allocation type is configured, the indication field contains N _RBG bits; where N _RBG is the total number of RBGs included in a BWP;

For the number of RBs included in the activated BWP, the formula uses the downlink activated BWP as an example for illustration. It can be understood that the formula can also be applied to the number of RBs included in the uplink activated BWP.

If only type 1 frequency domain resource allocation type is configured, the indication field contains

bit;

If both type 0 and type 1 are configured, the indication field contains

Bits, where the highest bit is used to indicate the resource allocation type used by the terminal, 0 means type 0, 1 means type 1.

Implementation Mode 1

Please refer to FIG. 2 , which is a method for determining the size of a resource allocation indication domain provided in Embodiment 1 of the present application. The method includes:

Step S210, the terminal device receives the downlink control information DCI sent by the network device. The DCI is used to schedule N channels, and the N channels are located in M serving cells and/or serving cell groups. N and M are positive integers, and M is less than or equal to N; wherein, the DCI includes a resource allocation indication field used to indicate the N channel resources; the number of bits corresponding to the resource allocation indication field is the first number of bits.

In one embodiment, M is a positive integer greater than or equal to 2, that is, the DCI schedules multiple serving cells and/or serving cell groups.

Wherein, the network device configures the terminal device with at least one serving cell and/or serving cell group through high-layer signaling. The serving cells and/or serving cell groups scheduled by the terminal device are all or part of all serving cells and/or serving cell groups configured by the network device. In addition, in Embodiment 1 of the present application, the serving cells that can be scheduled together by the same DCI are referred to as a serving cell group. The serving cell group that can be scheduled together by the same DCI can be configured by the network device, or can be determined according to all the serving cells configured by the network device and preset rules, or according to the configuration of the network device that belong to the same serving cell group All serving cells and preset rules are determined. The preset rule may be a combination or a combination rule of serving cells configured by the network or stipulated in an agreement. For example: in a specific embodiment, all the serving cells configured by the network equipment are 3 (Cell 1 to Cell 3), then the serving cell groups that can be scheduled together include: cell 1, cell 2, cell 3, cell 1+ There are seven combinations of cell 2, cell 1+cell 3, cell 2+cell 3, cell 1+cell 2+cell 3. Alternatively, the network device configures three serving cells (Cell 1 to Cell 3) belonging to the same serving cell group, then similarly, the combinations of serving cells that can be scheduled together also include these seven types. Alternatively, the network device configures only a part of these combinations as serving cell groups, such as: cell 1, cell 2, cell 3, cell 1+cell 2, cell 1+cell 3.

In one embodiment, Q channels among the N channels are located in the same serving cell or serving cell group in the M serving cells or/or serving cell groups, where Q is a positive integer, and the resource allocation The number of bits in the subfield corresponding to the Q channels in the indication field is the fourth number of bits.

In one embodiment, the first number of bits is determined according to the active bandwidth part BWP of the first serving cell and/or the active BWP group of each serving cell group in the first type of serving cell group. And/or, the fourth bit number is based on the activated BWP of the first serving cell and/or the activated BWP and the activated BWP of each serving cell group corresponding to the subfield in the first type of serving cell group /or activate BWP group determined.

Specifically, the manner of determining the first number of bits and the fourth number of bits includes the following two schemes respectively, or in other words, the first number of bits or the fourth number of bits can be determined according to the following two schemes; The subject of its determination can be a terminal device or a network device:

Option One

The first serving cell is a serving cell corresponding to the physical downlink control channel PDCCH detected by the terminal device. The first type of serving cell group is a cell group including the first serving cell, and/or, the first type of serving cell group is a serving cell group including a second type of serving cell group, wherein the second Channels of the second type of serving cell group and channels of the first serving cell may be scheduled by the same downlink control information DCI. In one embodiment, the detection mentioned in this application also includes the meaning of monitoring. It should be noted that the detection mentioned in various embodiments of the present application may include monitoring. In other words, the terminal device detects the DCI for the first serving cell. Or in other words, the network device configures the DCI for the search space set of the first serving cell. In other words, the candidate PDCCH (PDCCH candidate) where the DCI is located is determined according to the first serving cell. It can be seen that the first serving cell is a scheduled cell (scheduled cell), not a scheduling cell (scheduling cell).

It should be noted that the first type of serving cell group is a type of serving cell group, rather than a serving cell group, that is, a serving cell group that includes the first serving cell, or includes a group that can be identified by the same DCI as the first serving cell. The scheduled serving cells and/or serving cell groups of the serving cell group are all the first-type serving cell groups. At the same time, it should be noted that the serving cell group in the first type of serving cell group may only include one serving cell. Similarly, the activated BWP group corresponding to the serving cell group in the first type of serving cell group may also include only one activated BWP.

In a specific embodiment, assuming that cell 1 is the first serving cell, both cell 2 and cell 3 can be called by the same DCI as cell 1. Then, since the serving cell group cell 1 and cell 4 include cell 1, the serving cell group cell 1 and cell 4 belong to the first type of serving cell. Since cell 2 and cell 3 can be scheduled by the same DCI as cell 1, the serving cell groups cell 2 and cell 5, and the serving cell group cell 3 and cell 6 belong to the second type of serving cell group. Moreover, because cell 2 and cell 3 are scheduled by the same DCI as cell 1, they are also classified into the second type of serving cell group.

In the first type of manner of Solution 1, the first number of bits and the fourth number of bits may be directly determined according to the activated BWP and/or the activated BWP group, respectively. Through this relatively simple determination method, it only needs to be determined according to the size of the activated BWP and/or the size of the activated BWP group, and there is no need to map the BWP size to the number of bits required for resource scheduling; it is more applicable to the activated BWP configuration of all serving cells The resource indication type and/or RBG size etc. are the same.

It should be noted that, in this embodiment of the present application, the number of bits required for channel resource allocation of the serving cell or/or serving cell group refers to: when DCI schedules the serving cell or/or serving cell group, the The number of bits corresponding to the resource allocation indication field required by the channel indication resource of the serving cell or/or serving cell group. The number of bits required for channel resource allocation of the serving cell and/or serving cell group may also be expressed as the number of bits required for channel resource allocation of the serving cell and/or serving cell group.

In a specific embodiment, the first number of bits is determined according to the size of the activated BWP of the first serving cell, and/or the size of the activated BWP group of the second type of serving cell group.

Wherein, the first number of bits is determined according to one of the following values: the number of PRBs included in the activated BWP of the first serving cell; the number of PRBs included in the activated BWP of the first serving cell The sum of one value, the first value being the maximum value of the PRB numbers included in the activated BWP group of each serving cell group in the second type of serving cell group.

That is to say, the size of the active BWP can be expressed as the number of PRBs included in the active BWP. The number of PRBs included in the activated BWP group of each serving cell group in the second type of serving cell group includes one of the following: the sum of the number of PRBs of the activated BWPs of all cells included in each serving cell group; and/ Or, the maximum value of the number of PRBs with activated BWPs of all cells included in each serving cell group.

In a specific embodiment, if the first serving cell corresponds to the subfield, the fourth bit number is based on the size of the activated BWP of the first serving cell, and/or, is related to the subfield The size of the activated BWP group of the second type of serving cell group corresponding to the domain is determined.

Wherein, the fourth bit number is determined according to one of the following values: the number of PRBs included in the activated BWP of the first serving cell; the number of PRBs included in the activated BWP of the first serving cell and the second value In sum, the second value is the maximum value of the number of PRBs included in the activated BWP group of each serving cell group corresponding to the subfield in the second type of serving cell group. That is to say, in Solution 1, for the fourth bit number, if the first serving cell corresponds to the subfield, the fourth bit can be determined according to the activated BWP of the first serving cell number; if the first serving cell does not correspond to the subfield, the fourth bit number cannot be determined according to the activated BWP of the first serving cell.

That is to say, the size of the active BWP can be expressed as the number of PRBs included in the active BWP. The number of PRBs included in the activated BWP group of each serving cell group in the second type of serving cell group takes one of the following values: the sum of the number of PRBs of the activated BWPs of all cells included in each serving cell group; and /or, the maximum value of the number of PRBs for activating BWP of all cells included in each serving cell group.

In a specific embodiment, the first number of bits can also be determined according to the maximum value of the following values: the number of PRBs included in the activated BWP of the first serving cell, and the number of PRBs included in the activated BWP of the first serving cell group, and The number of PRBs included in the active BWP group of the serving cell group. And/or, the fourth number of bits can also be determined according to the maximum value of the following values: the number of PRBs contained in the activated BWP of the first serving cell and the number of PRBs included in the activated BWP group in the first type of serving cell group. The number of PRBs included in the active BWP and/or the active BWP group corresponding to the subfield.

Wherein, the number of physical resource block PRBs included in the activated BWP group of each serving cell group in the first type of serving cell group includes one of the following: the number of PRBs of activated BWPs of all cells included in each serving cell group The sum of ; the maximum value of the number of PRBs with activated BWP of all the cells included in each serving cell group.

In the second type of way of solution 1: the first number of bits or the fourth number of bits may also be determined according to the number of bits required to allocate resources for the serving cell. The advantage is that this determination method is more accurate, and it is applicable to situations where the resource indication type and RBG size configured by the activated BWPs of different serving cells are the same or different. details as follows:

In an embodiment, the first number of bits includes one of the following: a first number of sub-bits, and the first number of sub-bits is the number of bits required for channel resource allocation of the first serving cell; or, the The sum of the first number of sub-bits and the second number of sub-bits, wherein the second number of sub-bits is the number of bits required for channel resource allocation of each serving cell group in the second type of serving cell group maximum value; and/or,

If the first serving cell corresponds to the sub-field, the fourth bit number includes one of the following: a third sub-bit number, the third sub-bit number is set by the channel resource allocation of the first serving cell or the sum of the third sub-bit number and the fourth sub-bit number, wherein the fourth sub-bit number is the channel resource of each serving cell group in the second type of serving cell group Allocate the maximum number of bits required.

The number of bits required for channel resource allocation of each serving cell group in the second type of serving cell group includes one of the following: the sum of the number of bits required for channel resource allocation of each serving cell in each serving cell group and; or, the maximum number of bits required for channel resource allocation of each serving cell in each serving cell group.

In one embodiment, the first number of bits includes the maximum value of: the number of bits required for channel resource allocation of the first serving cell, and/or each serving cell in the first type of serving cell group The number of bits required for channel resource allocation of the group; and/or, the fourth number of bits includes the maximum value of the following: the number of bits required for channel resource allocation of the first serving cell corresponding to the subfield , and the number of bits required for channel resource allocation of each serving cell group in the first type of serving cell group corresponding to the subfield.

In one embodiment, the number of bits required to allocate resources for each serving cell group is: the sum of the number of bits required to allocate resources for channels of each serving cell included in each serving cell group, or , the maximum number of bits required for channel allocation resources of each serving cell included in each serving cell group.

Referring to FIG. 3 , the following is a specific example of Solution 1. In this example, the determination of the first number of bits is taken as an example for illustration. Assume that the network device configures four serving cells (cell 1~cell 4) for the terminal device through high-level signaling, and the combination of serving cells configured for the terminal device through high-level signaling is: cell 1~cell 4 can be used as a single service The cell is scheduled, cell 1 can be scheduled together with cell 2 or cell 3 or cell 4, cell 2 can be scheduled together with cell 3 or cell 1, the number of PRB (Physical Resource Block, physical resource block) in the figure is the service The number of PRBs included in the cell activation BWP (the numbers start from RB=0), among which cell 1~cell 4 are all configured to use type-0 resource allocation type, and the RBG size is configured as configuration 2 (that is, the RRC configuration parameter rbg -Size), so the RBG sizes used on cell 1 to cell 4 are 8RPB, 16PRB, 4PRB, and 4PRB respectively. Wherein, the first serving cell is cell 1, that is, the terminal device detects the PDCCH for cell 1, that is, schedules cell 1.

If the first number of bits is determined according to the activated BWP and/or activated BWP group, it is determined according to the maximum value of the number of PRBs contained in the activated BWP or activated BWP group of all serving cell groups in oval box 1:

Implementation method 1:

The PRBs of each combination are added first, and the maximum value is selected therefrom. Oval frame 1 contains four scheduling combinations: 1) scheduling cell 1 alone; 2) scheduling cell 1+cell 2; 3) scheduling cell 1+cell 3; 4) scheduling cell 1+cell 4, these four scheduling combinations The number of PRBs included in the serving cell group is: 50PRB, 50+100=150PRB, 50+30=80PRB, 50+20=70PRB, and the first bit number is determined according to the maximum value of the four PRB numbers, 150PRB;

Implementation 2:

First take the PRB with the maximum value in the second serving cell, and add the maximum value to the PRB value of the first serving cell. Take the maximum number of PRBs contained in the active BWP of cell 2, cell 3, and cell 4 that can be scheduled together with cell 1, that is, max{100PRB, 30PRB, 20PRB}=100PRB, so the first bit number is based on max{ The sum of 100PRB, 30PRB, 20PRB} and 50PRB (activated BWP of cell 1) is determined to be 150PRB.

If the first number of bits is determined according to the number of bits required for allocating resources, then according to the activated BWP or the size of the activated BWP group in all serving cell groups in the oval box 1, and/or the high-level parameter configured by the network device (for example: resourceAllocation), RBG size parameter, determine the number of bits required for scheduling the resource allocation of each serving cell group. The first number of bits is the maximum value of the above numbers of bits:

Implementation method 1:

Take the maximum value of the number of bits required by each serving cell in the second serving cell, and add the maximum value to the number of bits required by the first serving cell. According to the activated BWP size of cell 1 = 50PRB, and type0 resource allocation type, RBG size = 8PRB, the third bit number of cell 1 is determined to be 7 bits. Similarly, the third bit numbers of cell 2, cell 3, and cell 4 are respectively are: 7 bits, 8 bits, and 5 bits. Therefore, the first sub-bit number in method 1-2 is 7 bits, and the second sub-bit number is max{0, 7, 8, 5}=8 bits, which is specified by the FDRA field The corresponding number of bits is 7+8=15 bits;

Implementation 2:

The number of bits required by each serving cell combination is calculated first, and then the maximum value is selected. It may also be that the number of bits corresponding to the FDRA field is max{7, 7+7, 7+8, 7+5}=7+8=15 bits.

Similarly, if the first serving cell is cell 3, that is, the terminal detects the PDCCH for cell 3 (for scheduled cell 3), the number of bits occupied by the FDRA field is determined according to the serving cell group in the oval frame 2.

In addition, when the cells 1 to 4 correspond to the same subfield of the FDRA domain of DCI, the above method of determining the "first bit number" can also be used for the "fourth bit number" of the subfields corresponding to cell 1 to cell 4. Number" method of determination.

Option II

The first serving cell or the first type of serving cell group corresponding to the first bit number includes all serving cells or and/or serving cell groups that can be scheduled by the same DCI; and/or, the fourth bit number corresponds to The first serving cell or the first type of serving cell group includes all serving cells or and/or serving cell groups corresponding to the subfield that can be scheduled by the same DCI. That is to say, in solution 2, the first serving cell includes each serving cell that can be scheduled individually, and the first type of serving cell group includes every combination of serving cells that can be scheduled together.

The first kind of manner in solution 2: the first number of bits or the fourth number of bits may be determined according to the activated BWP of the serving cell or the activated BWP group of the serving cell group. Its advantage is that it is simpler than the first type of optional method in solution 1. Not only does it not need to map the BWP size to the number of bits required for resource scheduling, but also when the terminal device detects the DCI of different scheduled serving cells, It is the same DCI size, and the implementation of terminal equipment is simpler. details as follows:

In an embodiment, the first number of bits is determined according to the maximum of the following values: the number of PRBs included in the activated BWP of the first serving cell and the number of each serving cell in the first type of serving cell group The number of PRBs included in the active BWP group of the group. And/or, if the first serving cell corresponds to a subfield, the fourth number of bits is determined according to the maximum of the following values: the number of PRBs included in the activated BWP of the first serving cell, and the number of PRBs included in the first serving cell The number of PRBs included in the active BWP group of each serving cell group corresponding to the subfield in a type of serving cell group.

The second type of way in solution 2: the first number of bits or the fourth number of bits may also be determined according to the number of bits required for channel resource allocation of the serving cell or and/or serving cell group. The advantage is that it is more accurate than the first method in scheme 2, but simpler than the second method in scheme 1, and is applicable to the resource indication type and RBG size configured by the activated BWP of different serving cells. same or different situations. When the terminal device detects the DCI of different scheduled serving cells, the DCI size is the same, and the terminal implementation is simpler. However, the number of bits required by the FDRA domain is more than that of the second type of scheme. details as follows:

In one embodiment, the first number of bits is the maximum value of the following: the number of bits required for channel resource allocation of the first serving cell; each serving cell group in the first type of serving cell group The number of bits required for channel resource allocation. And/or, if the first serving cell corresponds to the subfield, the fourth number of bits is a maximum value including the following: the number of bits required for channel resource allocation of the first serving cell; The number of bits required for channel resource allocation of each serving cell group corresponding to the subfield in the first type of serving cell group.

In one embodiment, the number of bits required for channel resource allocation is determined according to at least one of the following: the size of the activated BWP and/or activated BWP group; the activated BWP and/or activated BWP group corresponds to resource allocation type; the resource allocation granularity corresponding to the activated BWP and/or activated BWP group.

In one embodiment, in Embodiment 1 of this application, the N channels may all be PDSCH, or all PUSCH, or part of PDSCH, part of PUSCH. When a serving cell is scheduled to be PDSCH, the activation The BWP refers to the activated downlink BWP, and when a serving cell is scheduled by the PUSCH, the activated BWP refers to the activated uplink BWP.

Please continue to refer to Figure 3, the following is a specific example of the second scheme. The configuration of the serving cell by the network device, the scheduling relationship, the type of resource allocation, the number of PRBs included in the activated BWP of the serving cell, and the RBG size are all consistent with the specific example of the above-mentioned scheme 1, and will not be repeated here. Similarly, the specific manner of the first bit is still taken as an example for illustration.

In solution two, when determining the first bitmap, no attention is paid to which serving cell is the scheduled serving cell, in other words, no attention is paid to which serving cell detects the PDCCH of the terminal device.

If the first number of bits is determined according to the activated BWP or activated PWB group: it is determined according to the maximum value of the number of PRBs included in the activated BWP or activated BWP group in the 8 serving cell groups on the right in FIG. 3 . Wherein, cell 1 to cell 4 in the 8 serving cell groups in FIG. 3 are combinations including only one serving cell. Specifically: the number of PRBs contained in the activated BWP or activated BWP group in the 8 serving cell groups are: 50, 100, 30, 20, 50+100, 50+30, 50+20, 100+30, then The first number of bits is determined according to the above maximum value of 50+100=150 PRB.

If the first number of bits is determined according to the number of bits required for resource allocation of each serving cell group: then according to the size of the activated BWP or activated PWB group in the 8 serving cell groups on the right side of Figure 3, and/or, the network device The configured high-level parameters (such as resourceAllocation) and RBG size parameters determine the number of bits required for scheduling the resource allocation of each serving cell group, and the first number of bits is the maximum value of the above-mentioned number of bits. Specifically: the number of bits required by each serving cell or serving cell group in the 8 serving cell groups is respectively

Then the first number of bits is 15, which is the maximum value among the above values.

In addition, when the cells 1 to 4 correspond to subfields of the same resource allocation indication field, the method of determining the above-mentioned "first bit number" can also be used for the "fourth bit number" corresponding to the subfields of cell 1 to cell 4. How to determine the number of bits".
