DETAILED DESCRIPTION

A Physical Downlink Control Channel (PDCCH) is a physical control channel in wireless communication networks, and it is used for scheduling and controlling downlink (DL) transmissions on a physical downlink shared channel (PDSCH) and uplink (UL) transmissions on a physical uplink shared channel (PUSCH) . Downlink Control Information (DCI) on a PDCCH includes at least downlink assignments, uplink scheduling grants, and other control information. User equipment (UE) monitors a set of PDCCH candidates in the configured monitoring occasions in one or more configured COntrol REsource SETs (CORESETs) according to the corresponding search space configurations to obtain relevant information and follows the instructions for data transmissions.

Different DCI formats are defined, including DCI format 1_0, DCI format 1_1, DCI format 1_2, DCI format 1_3, DCI format 0_0, DCI format 0_1, DCI format 0_2, DCI format 0_3, and more. The DCI fields for each DCI format are specified in an agreement. The structure has low flexibility for being updated according to network requirements.

The DCI fields for each DCI format are specified in the agreement. More specifically, which DCI fields are included in the DCI format and the order among these DCI fields are specified in the agreement, with a low flexibility to be updated according to network requirements. Each DCI field may include one or more bits that are used to indicate one type of information. Table 1 below shows exemplary implementations of different fields with respect to different DCI formats.

Table 1

Configuration of Improved DCI Structures

According to some embodiments of this disclosure, the fields in DCI can be divided into different functional blocks. Each functional block may include one or more fields. Additionally, the DCI includes a control block to indicate at least one of a structure of the functional blocks, whether a corresponding functional block has an indicative content, or the indication manner of the functional blocks.

The control block in DCI can be configured by RRC signaling. For example, a base station (BS) may send an RRC signaling to the UE to configure at least one of the structure, content, version, or characteristics of the control block. Likewise, the functional blocks of the DCI can be configured by RRC signaling. For example, the BS may send an RRC signaling to the UE to configured at least one of the structure, content, version, or characteristics of the functional blocks.

For example, the control block can be configured with at least one field (such as three fields) by RRC signaling. There can be one or more indications with a total of six bits in the DCI. The first field uses 1 bit to indicate two states of a corresponding functional block 1; the second field uses 2 bits to indicate four states of a corresponding functional block 2; the third field uses 3 bits to indicate eight states of a corresponding functional block 3. The total number of the bits of the three field is six. The number of the bits and the number of fields can be adjusted according to the need of the networks, and is not limited to the current example. The states of each functional block can be in a default state, in a changed state or in a state of one or more new content/information as shown in FIG. 3. The states of the functional blocks can be identified by the indications of the control block.

According to one embodiment, the functional blocks include at least one basic functional block. The basic functional block can be used for basic transmission control. The functional blocks may include one or more optional functional blocks. The optional functional blocks may include at least one of an AI functional block. An AI functional block can also be implemented by the basic functional block. The fields of basic functional blocks may include at least one of: Frequency domain resource assignments, Time domain resource assignments, Frequency hopping flags, Modulation and coding schemes, New data indicators, Redundancy versions, HARQ process numbers, or TPC commands for scheduled PUSCH for scheduling a UL grant. Likewise, the fields of basic functional blocks may include at least one of: Frequency domain resource assignments, Time domain resource assignments, VRB-to-PRB mapping, Modulation and coding schemes, New data indicators, Redundancy versions, HARQ process numbers, Downlink assignment indexes, TPC commands for scheduled PUCCH, or PDSCH-to-HARQ_feedback timing indicators, in a case of scheduling a DL grant.

FIG. 1 illustrates a process to construct a DCI structure for control of a DL grant. Based on the functional blocks, the different candidate fields in the respective functional blocks can be enabled or disabled; then, the different fields with the different functional blocks can be assembled in a sequence. The control block can be the leading part in the DCI. The control block may include different indicators to indicate the content, status, structure, or characteristics of the different fields of the different blocks. Likewise, FIG. 2 illustrates a process to construct a DCI structure for control of a UL grant. Based on the functional blocks, the different candidate fields in the respective functional blocks can be enabled or disabled; then, the different fields with the different functional blocks can be assembled in a sequence. The control block can be the leading part in the DCI. The control block may include different indicators to indicate the content, status, structure, or characteristics of the different fields of the different blocks.

Categories of Functional Blocks

According to some embodiments, the functional blocks can be categorized in different ways. For example, the functional blocks can be categorized based on their functions, their dimensions, their scenarios, or their use cases. For example, the different functional blocks can be categorized by the kinds of Multiple input Multiple output (MIMO) /Carrier aggregation (CA) /Power control (PC) /Power saving (PS) etc. Regarding use cases, the functional blocks can be categorized by the kinds of Enhanced Mobile broadband (eMBB) /Ultra reliable low latency communication (URLLC) /Ultra reliable low latency communication (MTC) /NR Unlicensed (NRU) etc. Table 2 below shows an exemplary approach to categorized different indicators or fields into different functional blocks according to the functions or use cases of the fields. Regarding different dimensions, the functional blocks can be categorized by the kinds of a time domain, a frequency domain, a spatial domain, or a power domain. Table 3 below shows an exemplary approach to categorized different indicators or fields into different functional blocks according to the controlled dimensions the fields. The number and function of the functional blocks can be expanded and changed, in view of the evolution of standard agreement and/or the network or applicaiton requirements. According to some examples, the functional blocks also can be used to group common DCI. For example, DCI formats 2-0/2-1/2-2/2-3/2-4/2-5/2-6/2-7 in NR can be used to group common DCI. Additionally or alternatively, the functional blocks also can be used for sidelink scheduling. Additionally or alternatively, the functional blocks also can be used for multicast or broadcast scheduling.

Table 2

Table 3

According to some examples, the fields in different functional block can be overlapped or not overlapped. That is, different or same fields may be configured in different functional blocks (while the content may be different in the fields of the same type in different functional blocks) . Likewise, the different functional blocks may have some different fields that does not appear in other functional blocks. Table 4 below shows an exemplary functional blocks and exemplary candidate fields that can be included in functional blocks and control block in a case of UL grant. Table 5 below shows an exemplary functional blocks and exemplary candidate fields that can be included such functional blocks and control block in a case of DL grant.

Table 5

Indication of DCI Size

In advanced network systems (such as 5G or 6G network systems, to which the examples of this disclosure are applicable) , the prediction capability of the AI/ML can be used to determine that some fields in function blocks can remain unchanged for a future period. The DCI bit overheads can be reduced, and the robustness of a PDCCH can be improved. Under this scheme, dynamically indication of a changed DCI size may be needed, so that the UE can perform blind detection. When the flexibility of constructing DCI increases, the indication of the information or structure of the DCI by the BS or the UE can help the receiver of the DCI interpret and use the DCI.

Grouping of UE

According to some examples, some combinations of fields in functional blocks can be configured by RRC signaling. For example, some states of the Resource Allocation functional block (as shown in FIG. 3) are notified in a separate or combined manner by the BS or UE via RRC signaling. The Resource Allocation Block can be configured with three states. The State 1 is default state. As compared with the default State 1, State 2 only indicated the changed states. The other omitted states in State 2 can be considered by the BS or UE as states remaining unchanged. The unchanged information is reused by the BS or UE, and is not added in the DCI to save the overhead. In State 3, the MCS1-new shows that the field can be used for different purposes. For example, the field can be used to point to a new MCS table, which can be a more precise table for data transmission.

Additionally or alternatively, multiples user ends (like UE) can be grouped together based on the operation of AI on the base station or core network. A group common DCI can be used to control multiple user ends in a same group. On the other hand, user ends in different UE groups can separately indicate different states of the Resource Allocation functional block.

Fields Reinterpretations

According to some embodiments, the DCI includes at least one field configured to represent two or more meanings at different conditions. Exemplarily, the different conditions are determined based on at least one of: an indicator of the DCI or a configuration of the DCI.

As an example, if the FDRA of resource allocation type 0 is set to all “0” or the FDRA of resource allocation type 1 is set to all “1” throughout a DCI format 1-1, some fields can be used to indicate Scell dormancy, which is different from their original function when the all “0” or all “1” conditions are not met. As examples, the field having different meanings under different conditions may include Modulation and coding schemes of transport block (5 bits available) , New data indicator of transport blocks (1 bit available) , Redundancy version of transport blocks (2 bits available) , HARQ process numbers (4 or 5 bits available) , Antenna port (s) (4/5/6 bit available) , or DMRS sequence initialization (1 bit available) .

These reinterpreted fields can be used to indicate the size of the changing DCI. An advantage of this approach is that a granularity may be relatively acceptable. Alternatively or additionally, the method may be used to enable or disable a DCI field or a combination fields or enable or disable a functional block as disclosed in this disclosure or to indicate a choice of a functional block state that can be predicted by AI/ML in advance. Additionally or alternatively, the fields used for re-interpreted can be further added, such as TDRA.

As an example, the reinterpreted field can use the first bit to indicate whether the certain indicators or fields are enabled or disabled as shown in Table 6.

Table 6

As an example, the reinterpreted field can use the first bit to indicate whether the certain functional blocks are enabled or disabled (present or not present) in DCI as shown in Table 7.

Table 7

According to some embodiments, the reinterpreted fields can use more than one bit to indicate more than one state of a certain field or functional block as shown in Table 8 below.

Table 8

DCI Corresponding to Multiple Resources

According to some embodiments, the use of a single piece of DCI can schedule multi-PxSCH (such as PDSCH, PUCCH, PDCCH) , as shown in FIG. 4. Exemplarily, the extended TDRA can be configured by RRC signalings to support a maximum of eight PxSCHs per TDRA table row. These PxSCH can be consecutive or non-consecutive, and each PxSCH corresponds to one K0/K2, SLIV, and mapping type. Exemplarily, each PxSCH’s first TB (transport block) uses the same MCS, but NDI and RV can be different. The HARQ process number of the first PxSCH can be indicated by the DCI, and the HARQ process number is incremented one by one.

According to some embodiments, in the application above, if most fields and/or blocks in the DCI remain unchanged, like the MCS field above. The DCI may extend the variable fields and/or blocks, such as the RV and NDI field above, to best use the space of the DCI. For example, the HARQ-ACK feedback block or the UCI block in the DCI can be extended. This approach may increase the single DCI overhead.

Additionally or alternatively, the DCI control block in above can include and additional RNTI format block, correspondingly for this application. As shown in FIG. 4, the RNTI of the DCI can be different corresponding to different slots scheduled by the DCI. Therefore, the RNTI format block can be configured to indicate by the BS or the UE to show the type of the RNTI of different slots. Table 9 below shows exemplary control block with the added RNTI format block.

Table 9

Additionally or alternatively, a single pieces of DCI can be used to schedule the different code words (CW) in a same slot, as shown in FIG. 5 below. For example in slot 6, a paging message is transmitted by using CW#1, and a data service is transmitted by using CW#2. They can be scheduled by a piece of DCI with different types of RNTI. In this case, the RNTI format block or indicator can also be added. Likewise, a single piece of DCI can be used to schedule multi-PxSCH in frequency domain, in this case the same measure can be added.

Implicit Notification

According to some embodiments, the method of this disclosure includes indicating the size of the DCI by implicit notification of the changed DCI size. For example, the number of RBs of frequency domain resource in the CORESET can be semi-static or dynamic changed to indicate a change in the number of DCI bit size. As an example, some correspondence between fields/blocks and the number of RBs of frequency domain resource are configured by RRC signalings, as shown in Tables 10 below. Therefore, the characteristics of the DCI (such as the number of RBs used to transmit the DCI) can be used to implicitly indicate at least one of the size, structure, content, or characteristics of the DCI.

Table 10

Additionally or alternatively, the number of symbols in the search space can be semi-static or dynamic and be changed to indicate a change in the number of DCI bit size. For example, some correspondence (as shown in Table 11 below) between the fields and blocks and the number of symbols in time domain are configured by RRC signaling.

Table 11

Additionally or alternatively, an aggregation level in the search space can be semi-static or dynamic and be changed to indicate a change in the number of DCI bit size. Below shows an exemplary structure of the indication.

Alternatively or additional, some AI fields can be used to trigger other associated AI fields or functional block. For example, the Transmission configuration indication field or Antenna ports field trigger a DCI field (e.g. FDRA) to be enabled or disabled, or trigger a combination fields, or enable or disable a functional block above or determine choice a functional block state.

This disclosure is intended to cover any conceivable variations, uses, combination, or adaptive changes of this disclosure following the general principles of this disclosure, and includes well-known knowledge and conventional technical means in the art and undisclosed in this application.

It is to be understood that this disclosure is not limited to the precise structures or operation described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from the scope of this application. The scope of this application is subject only to the appended claims.

The methods, devices, processing, circuitry, and logic described above may be implemented in many different ways and in many different combinations of hardware and software. For example, all or parts of the implementations may be circuitry that includes an instruction processor or controller, such as a Central Processing Unit (CPU) , microcontroller, or a microprocessor; or as an Application Specific Integrated Circuit (ASIC) , Programmable Logic Device (PLD) , or Field Programmable Gate Array (FPGA) ; or as circuitry that includes discrete logic or other circuit components, including analog circuit components, digital circuit components or both; or any combination thereof. The circuitry may include discrete interconnected hardware components or may be combined on a single integrated circuit die, distributed among multiple integrated circuit dies, or implemented in a Multiple Chip Module (MCM) of multiple integrated circuit dies in a common package, as examples.

Accordingly, the circuitry may store or access instructions for execution, or may implement its functionality in hardware alone. The instructions may be stored in a tangible storage medium that is other than a transitory signal, such as a flash memory, a Random Access Memory (RAM) , a Read Only Memory (ROM) , an Erasable Programmable Read Only Memory (EPROM) ; or on a magnetic or optical disc, such as a Compact Disc Read Only Memory (CDROM) , Hard Disk Drive (HDD) , or other magnetic or optical disk; or in or on another machine-readable medium. A product, such as a computer program product, may include a storage medium and instructions stored in or on the medium, and the instructions when performed by the circuitry in a device may cause the device to implement any of the processing described above or illustrated in the drawings.

The implementations may be distributed. For instance, the circuitry may include multiple distinct system components, such as multiple processors and memories, and may span multiple distributed processing systems. Parameters, databases, and other data structures may be separately stored and managed, may be incorporated into a single memory or database, may be logically and physically organized in many different ways, and may be implemented in many different ways. Example implementations include linked lists, program variables, hash tables, arrays, records (e.g., database records) , objects, and implicit storage mechanisms. Instructions may form parts (e.g., subroutines or other code sections) of a single program, may form multiple separate programs, may be distributed across multiple memories and processors, and may be implemented in many different ways. Example implementations include stand-alone programs, and as part of a library, such as a shared library like a Dynamic Link Library (DLL) . The library, for example, may contain shared data and one or more shared programs that include instructions that perform any of the processing described above or illustrated in the drawings, when performed by the circuitry.

In some examples, each unit, subunit, and/or module of the system may include a logical component. Each logical component may be hardware or a combination of hardware and software. For example, each logical component may include an application specific integrated circuit (ASIC) , a Field Programmable Gate Array (FPGA) , a digital logic circuit, an analog circuit, a combination of discrete circuits, gates, or any other type of hardware or combination thereof. Alternatively or in addition, each logical component may include memory hardware, such as a portion of the memory, for example, that includes instructions executable with the processor or other processors to implement one or more of the features of the logical components. When any one of the logical components includes the portion of the memory that includes instructions executable with the processor, the logical component may or may not include the processor. In some examples, each logical component may just be the portion of the memory or other physical memory that includes instructions executable with the processor or other processor to implement the features of the corresponding logical component without the logical component including any other hardware. Because each logical component includes at least some hardware even when the included hardware includes software, each logical component may be interchangeably referred to as a hardware logical component.

A second action may be said to be “in response to” a first action independent of whether the second action results directly or indirectly from the first action. The second action may occur at a substantially later time than the first action and still be in response to the first action. Similarly, the second action may be said to be in response to the first action even if intervening actions take place between the first action and the second action, and even if one or more of the intervening actions directly cause the second action to be performed. For example, a second action may be in response to a first action if the first action sets a flag and a third action later initiates the second action whenever the flag is set.

To clarify the use of and to hereby provide notice to the public, the phrases “at least one of <A> , <B> , …and <N> ” or “at least one of <A> , <B> , … <N> , or combinations thereof” or “ <A> , <B> , …and/or <N> ” are defined by the Applicant in the broadest sense, superseding any other implied definitions hereinbefore or hereinafter unless expressly asserted by the Applicant to the contrary, to mean one or more elements selected from the group comprising A, B, …and N. In other words, the phrases mean any combination of one or more of the elements A, B, …or N including any one element alone or the one element in combination with one or more of the other elements which may also include, in combination, additional elements not listed.
