Description

Method for determining size of resource allocation indication domain, terminal equipment and network equipment

Technical Field

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

Background

In an NR (New Radio) wireless access system, both uplink transmission and downlink transmission support two frequency domain resource allocation types: 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 higher layer 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 handover, the network side indicates the type of frequency domain resource allocation used by the terminal device through FDRA (Frequency domain resource assignment, frequency domain resource allocation indication field) in DCI (Downlink Control Information ).

If no BWP (Bandwidth Part) indication field is configured in the DCI for scheduling or the terminal device does not support the DCI-based BWP change, an RB (Resource Block) index corresponding to the frequency domain Resource allocation type is determined in the active BWP corresponding to the terminal device. If the terminal device supports a DCI-based BWP change and a BWP indication field is configured in the DCI for scheduling, a resource block RB index corresponding to the frequency domain resource allocation type is determined based on the BWP indicated by the BWP indication field in the DCI. Therefore, the terminal device needs to determine BWP through PDCCH (Physical Downlink Control Channel ) detection first, and then determine the frequency domain resource allocation in BWP.

And the NR system supports the terminal device to perform PDCCH blind detection in SSS (SEARCH SPACE SETS, search space set) configured on the network side. The "blind detection" is so called because the terminal device does not know information such as the DCI format before detecting the DCI carried by the PDCCH. Therefore, the terminal device needs to blindly detect the candidate PDCCHs in the search space set using some fixed DCI size. In order to reduce the complexity of blind detection of the PDCCH by the terminal device, NR specifies that after the step of aligning (DCI size alignment) the DCI sizes defined by the protocol is performed, the terminal device does not expect a total DCI size greater than 4 and a total DCI size of C-RNTI (Cell-Radio Network Temporary Identifier, cell radio network temporary identity) scrambling is greater than 3.

Since the terminal device only tries to detect the PDCCH using some fixed DCI sizes, it is required to know what the DCI sizes of different DCI formats are before the PDCCH is blindly detected. That is, the terminal device needs to know how many bits are included in each information field included in the DCI, such as FDRA fields (Frequency domain resource assignment, frequency domain resource allocation) indication fields, before PDCCH blind detection.

In embodiments of the present application, a cell Group (cell Group) is not limited to the proprietary concepts of a primary cell Group (MASTER CELL Group, MCG) and a secondary cell Group (Secondary Cell Group, SCG) in NR, and may refer broadly to a cell Group that includes at least one serving cell.

Referring to fig. 1, a wireless communication system 100 to which embodiments of the present application are applied is shown. The wireless communication system 100 includes: a network device 110, and at least one user device 120 located within the coverage area of the network device 110. The network device 110 sends a trigger signaling or DCI to the user device 120, and the user device 120 sends ACK/NACK feedback information to the network device according to the trigger signaling or DCI.

The wireless communication system 100 may include a plurality of network devices and may include other numbers of user devices within the coverage area of each network device, as the embodiments of the present application are not limited in this regard.

Wherein the network device 110 may provide communication coverage for a particular geographic area and may communicate with user equipment (e.g., UEs) located within the coverage area. The network device 100 may be a base station (Base Transceiver Station, BTS) in a GSM system or a CDMA system, a base station (NodeB, NB) in a WCDMA system, an evolved base station (Evolutional Node B, eNB or eNodeB) in an LTE system, or a radio controller in a cloud radio access network (Cloud Radio Access Network, CRAN), or the network device may be a relay station, an access point, a vehicle-mounted device, a wearable device, a network-side device in a 5G network, or a network device in a future evolved public land mobile network (Public Land Mobile Network, PLMN), etc.

The following embodiments of the present application will be described in detail, how a terminal device determines the channel resources during a process of scheduling a DCI (Downlink Control Information) for one or more serving cells and/or a channel of a serving cell group, and further how the terminal device determines the number of bits required for a resource allocation indication field when the PDCCH is blind-checked. Especially in case of scheduling channels of multiple serving cells and/or groups of serving cells, since the number of the multiple serving cells and/or groups of serving cells to be scheduled is not determined, and the size of the active BWP (i.e. the number of physical resource blocks PRB contained in the active BWP) or the size of the active BWP group on different serving cells is also not the same. Therefore, 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 DCI when one DCI schedules channels of a plurality of serving cells and/or a group of serving cells is a problem to be solved.

In the following embodiments of the present application, FDRA (Frequency domain resource assignment, frequency domain resource allocation) indication fields in DCI are taken as examples, which illustrate how a terminal device determines the size of FDRA fields in DCI in the case that one DCI schedules one or more serving cells and/or groups of serving cells, but the method and apparatus of the present application are not limited to determining the size of FDRA fields, and indication fields related to BWP size, higher layer configuration parameters such as TDRA (Time domain resource assignment, time domain resource allocation) indication fields in DCI, etc. are applicable. The frequency domain resources or frequency domain resource allocation indication fields appearing in the following description of the present application are understood to be specific examples of resources or resource allocation indication fields.

It should be noted that, the Type0 frequency domain Resource allocation Type supported by NR has a granularity of RBG (Resource Block Group ), where RBG is a combination of a series of consecutive virtual RBs (Resource Block), and the number of virtual RBs included in each RBG is determined according to the Size of BWP and RRC configuration parameter RBG-Size. The Type1 frequency domain resource allocation Type supported by NR may indicate a series of consecutive virtual RBs to the terminal, and the allocated starting RB (RBstart) and RB number (LRBs) are jointly encoded with one RIV (resource indication value, resource indicator value).

When the terminal device performs PDCCH blind detection, it needs to know what number of bits is included in each information field included in the DCI, and for example, the FDRA field is used to determine the number of bits as follows:

If only the type 0 frequency domain resource allocation type is configured, the indication domain contains N _RBG bits; wherein N _RBG is the total RBG number contained in one BWP; For activating the number of RBs contained in BWP, the formula is described using downlink BWP as an example, and it is understood that the formula can be applied to the number of RBs contained in uplink BWP.

If only the type 1 frequency domain resource allocation type is configured, the indication domain containsBits;

If both type 0 and type 1 are configured, the indication field contains Bits, wherein the most significant bit is used to indicate a resource allocation type used by the terminal, 0 represents type 0, and 1 represents type 1.

Embodiment one

Referring to fig. 2, a method for determining a size of a resource allocation indication field according to an embodiment of the present application includes:

Step S210, a terminal device receives downlink control information DCI sent by a network device, wherein the DCI is used for scheduling N channels, the N channels are positioned in M service cells and/or service cell groups, N, M is a positive integer, and M is less than or equal to N; wherein the DCI includes a resource allocation indication field for indicating the N channel resources; and the bit number corresponding to the resource allocation indication domain is a first bit number.

In an embodiment, where M is a positive integer greater than or equal to 2, i.e., where the DCI schedules multiple serving cells and/or groups of serving cells.

Wherein the network device configures at least one service cell and/or service cell group to the terminal device through higher layer signaling. The service cells and/or service cell groups scheduled by the terminal device are all or part of all the service cells and/or service cell groups configured for the network device. In addition, in the first embodiment of the present application, the serving cells that can be scheduled together by the same DCI are referred to as one serving cell group. The service cell group that can be scheduled together by the same DCI may be configured by the network device, or may be determined according to all the service cells configured by the network device and a preset rule, or may be determined according to all the service cells configured by the network device and belonging to the same service cell group and a preset rule. The preset rules may be a combination or combination rule of network configured or protocol agreed serving cells. For example: in a specific embodiment, all the serving cells configured by the network device are 3 (Cell 1 to Cell 3), and then the group of serving cells that can be scheduled together includes: seven combinations of cell 1, cell 2, cell 3, cell 1+cell 2, cell 1+cell 3, cell 2+cell 3, cell 1+cell 2+cell 3. Or 3 cells (Cell 1 to Cell 3) belonging to the same Cell group configured by the network device, the same can be scheduled together. Or the network device configures only a portion of this combination as a group of serving cells, such as: cell 1, cell 2, cell 3, cell 1+cel2, cell 1+cel3.

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

In an embodiment, the first number of bits is determined from the active bandwidth portion BWP of the first serving cell and/or the active BWP group of each of the first class of serving cell groups. And/or, the fourth bit number is determined according to the activated BWP of the first service cell and/or the activated BWP of each service cell group corresponding to the subdomain in the first type service cell group and/or the activated BWP group.

Specifically, the manner of determining the first bit number and the fourth bit number includes the following two schemes, respectively, or the first bit number or the fourth bit number may be determined according to the following two schemes; the determining body may be a terminal device or a network device:

Scheme one

The first serving cell is a serving cell corresponding to a physical downlink control channel PDCCH detected by the terminal equipment. The first type of service cell group is a cell group comprising the first service cell, and/or the first type of service cell group is a service cell group comprising a second type of service cell group, wherein a channel of the second type of service cell group and a channel of the first service cell can be scheduled by the same Downlink Control Information (DCI). In one embodiment, the detection of the present application also includes the meaning of monitoring. It should be noted that the detection according to the embodiments of the present application may include monitoring. In other words, the terminal device detects the DCI for the first serving cell. In another alternative, the network device configures the DCI for a set of search spaces of a first serving cell. In another embodiment, the candidate PDCCH (PDCCH candidate) in which 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 (scheduling cell) and 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, and not one serving cell group, that is, a serving cell group including the first serving cell, or a serving cell group including a serving cell or/and a serving cell group that can be scheduled by the same DCI as the first serving cell, are both first type of serving cell groups. Meanwhile, it should be noted that the serving cell group in the first type of serving cell group may include only one serving cell. Similarly, the active BWP group corresponding to the serving cell group in the first type of serving cell group may also include only one active BWP.

In one embodiment, assuming cell 1 is the first serving cell, both cell 2 and cell3 may be respectively invoked by the same DCI as cell 1. Then, the serving cell groups cell 1 and cell 4 belong to the first type of serving cell since they contain cell 1. And cell 2 and cell3 can be respectively scheduled by the same DCI as cell 1, and service cell groups cell 2 and cell 5 and service cell groups cell3 and cell 6 belong to the second type of service cell group. In addition, cell 2 and cell3 are also classified into the second type serving cell group by being scheduled by the same DCI as cell 1.

In a first type of approach of scheme one, the first number of bits and the fourth number of bits may be determined directly from an active BWP and/or an active BWP group, respectively. In this simpler determination, it is only necessary to determine the BWP size and/or the size of the active BWP group, and it is not necessary to map the BWP size to the number of bits required for resource scheduling; the method is more applicable to the same situation of the resource indication type and/or RBG size configured by the activated BWP of all the service cells.

In the embodiment of the present application, the number of bits required for channel resource allocation of the serving cell or/and the serving cell group refers to: and when the DCI schedules the service cell or/and the service cell group, the bit number corresponding to the resource allocation indication domain which is needed by the resource indication for the channel of the service cell or/and the service cell group. The number of bits required for allocation of channel resources for a serving cell and/or group of serving cells may also be expressed as the number of bits required for allocation of resources for a channel for a serving cell and/or group of serving cells.

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

Wherein the first number of bits is determined from one of the following values: the number of Physical Resource Blocks (PRBs) contained in the activated BWP of the first serving cell; the activated BWP of the first service cell includes a sum of a number of physical resource blocks PRBs and a first value, where the first value is a maximum value of the number of physical resource blocks PRBs included in the activated BWP group of each service cell group of the second class of service cell groups.

That is, the size of the active BWP may be expressed as the number of PRBs contained in the active BWP. The number of PRBs contained in the active BWP group of each serving cell group in the second class of serving cell groups includes one of: adding the PRB numbers of the activated BWPs of all cells contained in each service cell group; and/or, the maximum value of the number of PRBs of activated BWP of all cells contained in each service cell group.

In a specific embodiment, if the first serving cell corresponds to the subzone, the fourth number of bits is determined according to a size of an active BWP of the first serving cell and/or a size of an active BWP group of the second type serving cell group corresponding to the subzone.

Wherein the fourth number of bits is determined according to one of the following values: the number of Physical Resource Blocks (PRBs) contained in the activated BWP of the first serving cell; and the sum of the number of Physical Resource Blocks (PRBs) contained in the activated BWP of the first service cell and a second value, wherein the second value is the maximum value of the number of Physical Resource Blocks (PRBs) contained in the activated BWP group of each service cell group corresponding to the subdomain in the second type service cell group. That is, in the first aspect, for the fourth number of bits, if the first serving cell corresponds to the sub-domain, the fourth number of bits may be determined according to the active BWP of the first serving cell; if the first serving cell does not correspond to the subdomain, the fourth number of bits may not be determined according to the active BWP of the first serving cell.

That is, the size of the active BWP may be expressed as the number of PRBs contained in the active BWP. The number of PRBs contained in the active BWP group of each service cell group in the second class of service cell groups takes one of the following values: adding the PRB numbers of the activated BWPs of all cells contained in each service cell group; and/or, the maximum value of the number of PRBs of activated BWP of all cells contained in each service cell group.

In a specific embodiment, the first number of bits may be further determined according to a maximum value of the following values: the number of PRBs contained in the active BWP of the first service cell and the number of PRBs contained in the active BWP group of each service cell group of the first class of service cells. And/or, the fourth number of bits may be further determined according to a maximum value of the following values: and the number of PRBs contained in the activated BWP of the first service cell and the number of physical resource blocks PRBs contained in the activated BWP group and/or the activated BWP group corresponding to the subdomain in the activated BWP group of the first service cell.

Wherein the number of physical resource blocks PRB contained in the active BWP group of each serving cell group of the first class of serving cell groups includes one of the following: adding the PRB numbers of the activated BWPs of all cells contained in each service cell group; the maximum value of the number of PRBs of activated BWP of all cells contained in each service cell group.

In a second mode of scenario one: the first number of bits or the fourth number of bits may also be determined based on the number of bits required to allocate resources for the serving cell. The method has the advantages that the determination mode is more accurate, and the method is suitable for the condition that the resource indication types, RBG size and the like configured by the activated BWP of different service cells are the same or different. The method comprises the following steps:

In one embodiment, the first number of bits includes one of: a first number of sub-bits, the first number of sub-bits being a number of bits required for channel resource allocation of the first serving cell; or the sum of the first sub-bit number and a second sub-bit number, wherein the second sub-bit number is the maximum value of the bit numbers required by channel resource allocation of each service cell group in the second class of service cell groups; and/or the number of the groups of groups,

If the first serving cell corresponds to the subdomain, the fourth number of bits includes one of: a third number of sub-bits, the third number of sub-bits being a number of bits required for channel resource allocation of the first serving cell; or the sum of the third sub-bit number and a fourth sub-bit number, wherein the fourth sub-bit number is the maximum value of the bit numbers required by the channel resource allocation of each service cell group in the second class of service cell groups.

The number of bits required for channel resource allocation for each of the second class of cell groups includes one of: adding the bit number required by channel resource allocation of each service cell in each service cell group; or the maximum value of the bit number required by the channel resource allocation of each serving cell in each serving cell group.

In one embodiment, the first number of bits includes a maximum of: the number of bits required for channel resource allocation of the first service cell and/or the number of bits required for channel resource allocation of each service cell group in the first type of service cell group; and/or, the fourth number of bits comprises a maximum of: the number of bits required for channel resource allocation of the first serving cell corresponding to the subzone, and the number of bits required for channel resource allocation of each serving cell group in the first type of serving cell groups corresponding to the subzone.

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 for allocating resources to the channels of each service cell contained in each service cell group, or the maximum number of bits required for allocating resources to the channels of each service cell contained in each service cell group.

Referring to fig. 3, the following is a specific example of the scheme one, in which the determination of the first bit number is taken as an example for illustration. Assume that the network device configures 4 service cells (cell 1 to cell 4) for the terminal device through higher layer signaling, and the combination between the service cells configured for the terminal device through higher layer signaling is: cells 1-4 can be scheduled as separate serving cells, 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 PRBs (Physical Resource Block, physical resource blocks) in the figure is the number of PRBs (numbering starts from rb=0) contained in the activated BWP of the serving cell, where cells 1-cell 4 are configured with type-0 resource allocation type, and RBG Size is configured as configuration 2 (i.e. by RRC configuration parameter RBG-Size), so RBG sizes used on cells 1-cell 4 are 8RPB, 16PRB, 4PRB, respectively. 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 active BWP and/or the active BWP group, it is determined according to the maximum value of the active BWP of all the service cell groups in oval 1 or the number of PRBs contained on the active BWP group:

Implementation 1:

The PRBs of each combination are added first, and the maximum value is selected from the PRBs. Oval 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, wherein the number of PRBs included in the service cell groups of the four scheduling combinations is respectively as follows: 50 PRBs, 50+100=150 PRBs, 50+30=80 PRBs, 50+20=70 PRBs, the first number of bits being determined according to a maximum of 150 PRBs of the four PRBs;

implementation 2:

The PRB of the maximum value in the second serving cell is taken first and added to the PRB value of the first serving cell. The number of PRBs involved in the active BWP of cell 2, cell 3, cell 4 that can be scheduled together with cell 1 is maximized, i.e. max {100PRB, 30PRB, 20PRB } = 100PRB, so the first number of bits is determined from the sum of max {100PRB, 30PRB, 20PRB }, and 50PRB (active BWP of cell 1), 150PRB.

If the first number of bits is determined according to the number of bits required for allocating resources, the number of bits required for scheduling the resource allocation of each service cell group is determined according to the size of the active BWP or the active BWP group in all the service cell groups in oval 1 and/or higher layer parameters (e.g. resourceAllocation), RBG size parameters configured by the network device. The first number of bits is the maximum value of the above numbers of bits:

Implementation 1:

Taking the maximum value of the number of bits required for each of the second cells and adding the maximum value to the number of bits required for the first cell. According to the activated BWP size=50 PRB of cell 1, the type0 resource allocation type, RBG size=8 PRB, the third bit number of cell 1 is determined to be 7 bits, and similarly, the third bit numbers of cell 2, cell 3 and cell 4 are respectively: 7 bits, 8 bits, 5 bits, so the first number of sub-bits in method 1-2 is 7 bits, the second number of sub-bits is max {0, 7, 8, 5} = 8 bits, and the number of bits corresponding to FDRA FIELD is 7+8 = 15 bits;

implementation 2:

The number of bits required by each cell combination is calculated and the maximum value is selected. The number of bits corresponding to FDRA FIELD may be 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 PDCCH for cell 3 (for scheduled cell) then determines FDRA FIELD the number of bits occupied by the serving cell group of oval 2.

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

Scheme II

The first service cell or the first type of service cell group corresponding to the first bit number comprises all service cells or/and service cell groups which can be scheduled by the same DCI; and/or, the first service cell or the first type service cell group corresponding to the fourth bit number includes all service cells or/and service cell groups corresponding to the subdomains and capable of being scheduled by the same DCI. That is, in scheme two, the first serving cell includes each serving cell that can be individually scheduled, and the first type of serving cell group includes each serving cell combination that can be scheduled together.

The first mode in scheme II is: the first or fourth number of bits may be determined according to an active BWP of a serving cell group or an active BWP group of a serving cell group. The method has the advantages that compared with the first type of alternative mode in the first scheme, the method is simpler, BWP size does not need to be mapped into the bit number required by resource scheduling, and terminal equipment is the same DCI size when detecting DCIs of different scheduled service cells, so that the terminal equipment is simpler to realize. The method comprises the following steps:

In one embodiment, the first number of bits is determined from the maximum of the following values: the activated BWP of the first service cell includes a number of PRBs and the activated BWP of each of the first class of service cell groups includes a number of PRBs. And/or, if the first serving cell corresponds to a subdomain, the fourth number of bits is determined according to a maximum value of the following values: the number of PRBs included in the active BWP of the first serving cell and the number of PRBs included in the active BWP group of each serving cell group corresponding to the subzone in the first type of serving cell groups.

In one embodiment, the number of PRBs contained in the active BWP group of each serving cell group of the first class of serving cell groups takes one of the following values: adding the PRB numbers of the activated BWPs of all cells contained in each service cell group; the maximum number of PRBs of activated BWP of all cells contained in each service cell group.

The second mode in scheme II: the first number of bits or the fourth number of bits may also be determined based on the number of bits required for channel resource allocation of the serving cell or and/or the group of serving cells. The method has the advantages that compared with the first type of method in the second scheme, the method is more accurate, but compared with the second type of method in the first scheme, the method is simpler, and the method is applicable to the condition that the resource indication types, RBG sizes and the like configured by the activated BWP of different service cells are the same or different. When the terminal equipment detects DCIs of different scheduled service cells, the DCIs are the same, the terminal implementation is simpler, but the number of bits required by FDRA fields is more than that of a second type mode. The method comprises the following steps:

in one embodiment, the first number of bits is a maximum value comprising: the channel resource of the first service cell is allocated with the required bit number; the number of bits required for channel resource allocation for each of the first class of cell groups. And/or, if the first serving cell corresponds to the subdomain, the fourth number of bits is a maximum value including: the number of bits required for channel resource allocation of the first serving cell; and the number of bits required for channel resource allocation of each service cell group corresponding to the subdomain in the first service cell group.

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

In an embodiment of the present application, the N channels may be all PDSCH, or all PUSCH, or part of PDSCH, or part of PUSCH, and the active BWP refers to active downlink BWP when one serving cell is scheduled PDSCH, and the active BWP refers to active uplink BWP when one serving cell is scheduled PUSCH.

With continued reference to fig. 3, the following is a specific example of scenario two. The configuration, the scheduling relationship, the resource allocation type, the number of PRBs included in the serving cell activation BWP, and the RBG size of the serving cell by the network device are consistent with the specific examples of the first scheme, and are not repeated herein. Also, the specific manner in which the first bit is described is also illustrated as an example.

In the second scheme, in determining the first bit pattern, it is not focused on which serving cell is the scheduled serving cell, in other words, the terminal device detects which serving cell detects the PDCCH.

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

If the first bit number is determined according to the bit number required by the resource allocation of each service cell group: the number of bits needed to schedule the resource allocation for each cell group is determined based on the active BWP or active PWB group size in the 8 cell groups on the right side of fig. 3 and/or the higher layer parameters (e.g., resourceAllocation), RBG size parameters configured by the network device, which is the maximum of the above-mentioned number of bits. Specifically: the number of bits required for each of the 8 cell groups or the cell group is respectively The first number of bits is the maximum 15 of the above values.

In addition, when the cells 1 to 4 correspond to the subzones of the same resource allocation indication domain, the above determination method of the "first bit number" may also be used for the determination method of the "fourth bit number" of the subzones corresponding to the cells 1 to 4.

In the first embodiment of the present application, in the case where one DCI schedules one or more cells or service cell groups, how to calculate the number of bits of the resource allocation indication field of the DCI according to the activated BWP or the activated BWP group of the scheduled service cell or and/or service cell group, so as to obtain a certain DCI size, so that even if the DCI schedules one or more cells or/and service cell groups, PDCCH blind detection can be performed, thereby solving the technical problems existing in the prior art.
