[0017] A physical downlink control channel (PDCCH) is a physical control channel in a wireless communication network that is used to schedule and control DL transmissions on a physical downlink shared channel (PDSCH) and UL transmissions on a physical uplink shared channel (PUSCH). DCI on the PDCCH includes at least downlink assignments, uplink scheduling grants, and other control information. A user equipment (UE) monitors a set of PDCCH candidates at configured monitoring occasions in one or more configured control resource sets (CORESETs) according to corresponding search space configurations to obtain relevant information and follow instructions for data transmission.

[0018] 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 so on. DCI fields for each DCI format are specified in the protocol. The structure has low flexibility in updating according to network requirements.

[0019] DCI fields for each DCI format are specified in the protocol. More specifically, which DCI fields are included in a DCI format and the order among these DCI fields are specified in the protocol, with low flexibility in updating according to network requirements. Each DCI field can include one or more bits that are used to indicate a type of information. Table 1 below shows exemplary implementations of different fields under different DCI formats.

[0024]

[0025] Configuration of improved DCI structure

[0026] According to some embodiments of the disclosure, the fields in the DCI can be divided into different functional units. Each functional unit can include one or more fields. In addition, the DCI includes a control unit for indicating at least one of the following: the structure of the functional units, whether the corresponding functional unit has indicative content, or the indication manner of the functional units.

[0027] The control unit in the DCI can be configured by RRC signaling. For example, a Base Station (BS) can send RRC signaling to a UE to configure at least one of the structure, content, version, or characteristic of the control unit. Likewise, the functional units of the DCI can be configured by RRC signaling. For example, the BS can send RRC signaling to the UE to configure at least one of the structure, content, version, or characteristic of the functional units.

[0028] For example, the control unit can be configured by RRC signaling to have at least one field (such as three fields). There can be one or more indications in the DCI, for a total of six bits. The first field uses 1 bit to indicate two states of the corresponding functional unit 1; the second field uses 2 bits to indicate four states of the corresponding functional unit 2; and the third field uses 3 bits to indicate eight states of the corresponding functional unit 3. The total number of bits for the three fields is six. The number of bits and the number of fields can be adjusted according to network needs, and are not limited to the current example. The state of each functional unit can be in a default state, in a changed state, or in a state of one or more new contents / information, as shown in Figure 3 The state of the functional unit can be identified by the indication of the control unit.

[0029] According to one embodiment, the functional units include at least one basic functional unit. The basic functional unit can be used for basic transmission control. The functional units can include one or more optional functional units. The optional functional units can include at least one of the AI functional units. The AI functional units can also be implemented by the basic functional unit. In the case of scheduling a UL grant, the fields of the basic functional unit can include at least one of the following: frequency domain resource allocation, time domain resource allocation, frequency hopping flag, modulation and coding scheme, new data indicator, redundancy version, HARQ process number, or TPC command for the scheduled PUSCH. Likewise, in the case of scheduling a DL grant, the fields of the basic functional unit can include at least one of the following: frequency domain resource allocation, time domain resource allocation, VRB-to-PRB mapping, modulation and coding scheme, new data indicator, redundancy version, HARQ process number, downlink assignment index, TPC command for the scheduled PUCCH, or PDSCH-to-HARQ_feedback timing indicators.

[0030] Figure 1 A procedure for constructing a DCI structure for controlling DL grant is shown. Based on the functional units, different candidate fields in the corresponding functional units can be enabled or disabled; then, different fields in different functional units can be assembled in sequence. The control unit can be the leading part in the DCI. The control unit can include different indicators for indicating the content, status, structure or characteristics of different fields of different blocks. Likewise, Figure 2 A procedure for constructing a DCI structure for controlling UL grant is shown. Based on the functional units, different candidate fields in the corresponding functional units can be enabled or disabled; then, different fields in different functional units can be assembled in sequence. The control unit can be the leading part in the DCI. The control unit can include different indicators for indicating the content, status, structure or characteristics of different fields of different blocks.

[0031] Category of functional units

[0032] According to some embodiments, the functional units can be categorized in different ways. For example, the functional units can be categorized based on their functions, their dimensions, their scenarios, or their use cases. For example, different functional units can be categorized by Multiple Input Multiple Output (MIMO) / Carrier Aggregation (CA) / Power Control (PC) / Power Saving (PS), etc. categories. Regarding use cases, the functional units can be categorized by Enhanced Mobile broadband (eMBB) / Ultra Reliable Low Latency Communication (URLLC) / Ultra Reliable Low Latency Communication (MTC) / NR Unlicensed (NRU), etc. categories. Table 2 below shows an exemplary method of categorizing different indicators or fields into different functional units according to the functions or use cases of the fields. Regarding different dimensions, the functional units can be categorized by time domain, frequency domain, spatial domain, or power domain categories. Table 3 below shows an exemplary method of categorizing different indicators or fields into different functional units according to the controlled dimensions of the fields. The number and functions of the functional units can be extended and changed based on the evolution of standard protocols and / or network or application requirements. According to some examples, the functional units can also be used for 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 for group common DCI. Additionally or alternatively, the functional units can also be used for sidelink scheduling. Additionally or alternatively, the functional units can also be used for multicast or broadcast scheduling.

[0038]

[0039] According to some examples, fields in different functional units can overlap or not overlap. That is, different or same fields can be configured in different functional units (while the content of the same type of field can be different in different functional units). Also, different functional units can have some different fields that are not present in other functional units. Table 4 below shows example functional units in the case of UL grant and example candidate fields that can be included in the functional units and control units. Table 5 below shows example functional units in the case of DL grant and example candidate fields that can be included in such functional units and control units.

[0045]

[0046] Indication of DCI size

[0047] In advanced network systems (such as 5G or 6G network systems, examples of the present disclosure are applicable to these systems), the prediction capability of AI / ML can be used to determine that some fields in the functional units can remain unchanged in future time periods. This can reduce the DCI bit overhead and can improve the robustness of PDCCH. Under this scheme, it can be necessary to dynamically indicate the changed DCI size so that the UE can perform blind detection. When the flexibility of constructing DCI increases, the indication of the information or structure of DCI by the BS or UE can help the receiver of DCI to interpret and use the DCI.

[0048] Grouping of UEs

[0049] According to some examples, some combinations of fields in the functional units can be configured by RRC signaling. For example, the Resource Allocation functional block (e.g., Resource Allocation 1, Resource Allocation 2, and Resource Allocation 3 in Table 4) can be configured by RRC signaling. Figure 3Some of the states (shown) are signaled by the BS or UE via RRC signaling in a separate or combined manner. The Resource Allocation Block can be configured in three states. State 1 is the default state. State 2 indicates only the changed state compared to the default state 1. The other omitted states in state 2 can be considered by the BS or UE as the unchanged state. The unchanged information is reused by the BS or UE and the unchanged information is not added to the DCI to save overhead. In state 3, MCS1-new indicates that this field can be used for different purposes. For example, this field can be used to point to a new MCS table, which can be a more accurate table for data transmission.

[0050] Additionally or alternatively, multiple user ends (e.g., UEs) can be grouped together based on AI operations on the base station or core network. Group common DCI can be used to control multiple user ends in the same group. On the other hand, user ends in different UE groups can indicate different states of the Resource Allocation functional block respectively.

[0051] Field re-interpretation

[0052] According to some embodiments, the DCI includes at least one field configured to represent two or more than two meanings under 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.

[0053] For 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” in the entire DCI format 1-1, some fields can be used to indicate secondary cell (Scell) dormancy, which is different from the original function of these fields when the all “0” or all “1” condition is not met. As an example, the fields with different meanings under different conditions can include: modulation and coding scheme of transport block (5 bits available), new data indicator of transport block (1 bit available), redundancy version of transport block (2 bits available), HARQ process number (4 or 5 bits available), antenna port (4 / 5 / 6 bits available), or DMRS sequence initial configuration (1 bit available).

[0054] These reinterpreted fields can be used to indicate varying sizes of DCI. The advantage of this approach is that the granularity can be relatively acceptable. Alternatively or additionally, this approach can be used to enable or disable DCI fields or combine fields, or to enable or disable functional units as disclosed in this disclosure, or to indicate a selection of functional unit states that can be pre-predicted by AI / ML. Additionally or alternatively, fields for re-interpretation can be further added, such as TDRA.

[0055] As an example, the reinterpreted fields can use the first bit to indicate whether certain indicators or fields are enabled or disabled, as shown in Table 6.

[0056] Table 6

[0057]

[0058] As an example, the reinterpreted fields can use the first bit to indicate whether certain functional units are enabled or disabled (present or not present) in the DCI, as shown in Table 7.

[0059] Table 7

[0060]

[0061] 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 unit, as shown in Table 8 below.

[0062] Table 8

[0063]

[0064] DCI corresponding to multiple resources

[0065] According to some embodiments, multiple PxSCHs (such as PDSCH, PUCCH, PDCCH) can be scheduled using a single DCI, as shown in Table 9. Figure 4 Exemplarily, the extended TDRA can be configured by RRC signaling to support up to eight PxSCHs per TDRA table row. These PxSCHs can be contiguous or non-contiguous, and each PxSCH corresponds to one K0 / K2, Start and Length Indication Value (SLIV), and mapping type. Exemplarily, the first transport block (TB) of each PxSCH uses the same MCS, but the 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 by one for each PxSCH.

[0066] According to some embodiments, in the above application, if most of the fields and / or blocks in the DCI remain unchanged, such as the above-mentioned MCS field, the DCI can expand the variable fields and / or blocks (such as the above-mentioned RV and NDI fields) to best utilize the space of the DCI. For example, the HARQ-ACK feedback block or the UCI block in the DCI can be expanded. This method can increase the overhead of a single DCI.

[0067] Additionally or alternatively, the above-mentioned DCI control unit can include an additional Radio Network Temporary Identifier (RNTI) format block, which is correspondingly used for this application. As shown in Table 8, the RNTI of the DCI can correspond to different time slots scheduled by the DCI. Therefore, the RNTI format block can be configured to be indicated by the BS or the UE to show the type of RNTI of different time slots. Table 9 below shows an exemplary control unit with the added RNTI format block. Figure 4

[0068] Table 9

[0069]

[0070] Additionally or alternatively, a single DCI can be used to schedule different code words (CWs) in the same time slot, as shown in the following Figure 5 For example, in time slot 6, a paging message is transmitted using CW#1, and a data service is transmitted using CW#2. The paging message and the data service can be scheduled by a single DCI with different types of RNTI. In this case, an RNTI format block or indicator can also be added. Similarly, a single DCI can be used to schedule multiple PxsCHs in the frequency domain, in which case the same metric can be added.

[0071] Implicit notification

[0072] According to some embodiments, the method of the present disclosure includes indicating the size of the DCI through implicit notification of the changed DCI size. For example, the number of RBs of the frequency domain resource in the CORESET can be semi-statically or dynamically changed to indicate the change in the number of DCI bit sizes. As an example, some correspondence between the fields / blocks and the number of RBs of the frequency domain resource is configured through RRC signaling, as shown in Table 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.

[0073] Table 10

[0074]

[0075] ​Additionally or alternatively, the number of symbols in the search space can be semi-static or dynamic and can be changed to indicate the change of the number of DCI bit sizes. For example, some correspondence between the field and the number of symbols in time domain can be configured by RRC signaling (as shown in Table 11 below).

[0076] Table 11

[0077]

[0078] Additionally or alternatively, the aggregation level in the search space can be semi-static or dynamic and can be changed to indicate the change of the number of DCI bit sizes. An exemplary structure of the indication is shown below.

[0079]

[0080] Alternatively or additionally, some AI fields can be used to trigger other associated AI fields or functional units. For example, the transmission configuration indication field or the antenna port field triggers the DCI field (e.g. FDRA) to be enabled or disabled, or triggers the combination field, or enables or disables the upper functional unit or determines the selection functional unit state.

The instructions can be stored in a tangible storage medium such as flash memory, random access memory (RAM), read only memory (ROM), erasable programmable read only memory (EPROM), or others, or on a magnetic or optical disk, such as a compact disc read only memory (CDROM), an optical disc drive, or other disk or disk drive, or in or on another machine readable medium. A product such as a computer program product can include a storage medium and storage medium having stored therein instructions, and the instructions when executed by circuitry in an apparatus can cause the apparatus to implement any of the processes described above or illustrated in the drawings.

[0130] Implementations can be distributed. For example, the circuitry can include multiple distinct systems components, such as a plurality of processors and memories, and can span multiple distributed processing systems. Parameters, databases, and other data structures can be stored locally and managed separately, can be consolidated into a single memory or database, can be logically and physically organized in many different ways, and can be implemented in many different ways. Exemplary implementations include linked lists, program variables, hash tables, arrays, records (e.g., database records), objects, and implicit storage mechanisms. Instructions can form part of a single program (e.g., a subroutine or other code segment), can form multiple separate programs, can be distributed across multiple memories and processors, and can be implemented in many different ways. Example implementations include standalone programs, as well as part of a library, such as a shared library (DLL) or other shared library. For example, the library can contain shared data and one or more shared programs that include instructions that, when executed by circuitry, perform any of the processes described above or illustrated in the drawings.

[0131] In some examples, each unit, sub-unit, and / or module of the system can include a logic component. Each logic component can be hardware or a combination of hardware and software. For example, each logic component can include an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), digital logic circuits, analog circuits, combinations of discrete circuits, gates, or any other type of hardware or combination thereof. Alternatively or additionally, each logic component can include memory hardware, such as a portion of memory, for example, that includes instructions executable by a processor or other processor to implement one or more features of the logic component. When any one logic component includes a portion of memory that includes instructions executable by a processor, the logic component can or can not include the processor. In some examples, each logic component can simply be a portion of memory or other physical memory that includes instructions executable by a processor or other processor to implement features of the corresponding logic component, without the logic component including any other hardware. Since each logic component includes at least some hardware, even if the included hardware includes software, each logic component can be referred to interchangeably as a hardware logic component.

[0132] A second action can be said to be "in response to" a first action regardless of whether the second action is directly or indirectly caused by the first action. The second action can occur much later in time than the first action and still be in response to the first action. Similarly, the second action can be said to be in response to the first action even if intervening actions occur 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, if a first action sets a flag, a second action can be in response to the first action and a third action later initiates the second action upon the flag being set.

[0133] For the avoidance of doubt and to provide notice to the public, the Applicant defines the phrase "at least one of , ,... and <N>" or "at least one of , ,... <N> or combinations thereof" or ", ,... and / or <N>" in the broadest sense, to mean one or more elements from the group consisting of A, B,... and N, in the broadest sense, unless the application expressly states otherwise. In other words, the phrase means any combination of one or more of the elements A, B,... or N including any one of those elements alone or in combination with one or more of the other elements which can also be present in combination.
