Fig. 1 is a schematic flow chart diagram illustrating a method of information domain determination according to an embodiment of the present disclosure. The information domain determining method shown in the embodiment may be executed by a terminal, where the terminal includes, but is not limited to, a mobile phone, a tablet computer, a wearable device, a sensor, an internet of things device, and other communication devices. The terminal may communicate with network devices including, but not limited to, network devices in 4G, 5G, 6G, etc., communication systems, e.g., base stations, core networks, etc.

As shown in fig. 1, the information domain determining method may include the steps of:

in step S101, the size (i.e., the number of occupied bits, also referred to as the length) of at least one information field (the information field may also be simply referred to as the field) in downlink control information MC (Multi-cell) -DCI for scheduling a plurality of cells is determined according to any one of the following information: configuration signaling; predefined conditions; the size of at least one information field in the legacy downlink control information.

The embodiment of the disclosure provides MC-DCI, which can be used for scheduling a plurality of cells, and concretely can be used for scheduling data of the plurality of cells, such as PUSCH, PDSCH and the like of one or more cells in the plurality of cells, so that the plurality of cells are scheduled through one DCI.

In one embodiment, the terminal may receive the MC-DCI in a scheduling cell (for example, a cell where the terminal receives the MC-DCI), where the cell scheduled by the MC-DCI may be referred to as a scheduled cell, which refers to all or part of all cells that can be scheduled by the MC-DCI, where the cell that can be scheduled by the MC-DCI may be determined according to configuration information of a network device, or may be determined according to a predefined rule, which is not limited in this disclosure. The cell scheduled by the MC-DCI, namely the cell to be scheduled, is the cell actually scheduled by the MC-DCI, and the cell which can be scheduled by the MC-DCI is used for representing the capacity range of the MC-DCI, and the cell to be scheduled belongs to the cell set which can be scheduled by the MC-DCI.

At least one field (field) is set in the MC-DCI, where the indication information of the first field in the MC-DCI is used to schedule one or more of the scheduled cells, and the indication information of each of the scheduled cells that is scheduled by the MC-DCI at the same time is the same, in which case the manner in which the MC-DCI schedules multiple cells may be referred to as Type-1A. The first information field does not refer specifically to a certain information field but to any one of the at least one information field.

Since one DCI is used to schedule only one cell in the related art, an information field (e.g., a value of the information field) in the DCI is only suitable for indicating for the one scheduled cell. For example, taking the bandwidth part indication (BandWidth Part Indicator) as an information field, bandwidth part indication information in DCI in the related art may be used to indicate whether a scheduled cell switches bandwidth part BWP.

And, based on the present embodiment, the bandwidth part indication information field in the MC-DCI may be used to indicate whether all the scheduled cells switch BWP. In this process, the terminal needs to determine the size of the information domain, and further determine the information domain value, so as to know what information is specifically indicated by the information domain.

In one embodiment, a terminal may receive a first configuration signaling, e.g., radio resource control (Radio Resource Control, RRC) signaling, that schedules transmission of a cell, and determine a size of at least one information field in the MC-DCI based on the first configuration signaling. It should be noted that, in the related art, there is no first configuration signaling for configuring a size of at least one information field in the MC-DCI.

In one embodiment, the terminal may determine a reference cell among a plurality of scheduled cells that can be scheduled by the MC-DCI, and receive a second configuration signaling, for example, RRC signaling, at the reference cell, and determine a size of at least one information field in the MC-DCI according to the second configuration signaling of the reference cell, or, in case that a predefined condition of the reference cell has an association with the size of at least one information field in the MC-DCI, may determine the size of at least one information field in the MC-DCI in the association according to the predefined condition of the reference cell.

In one embodiment, the terminal may determine the size for at least one information field in the MC-DCI according to the size of at least one information field in legacy (legacy) downlink control information, for example, the size of the first information field in legacy DCI is taken as the size of the first information field in the MC-DCI.

Here, legacy DCI refers to DCI already specified in the related art, including but not limited to DCI 1_0 configured in a common search space (Common Search Space, CSS), DCI 0_0 configured in a CSS, DCI 1_0 configured in a terminal specific search space (UEspecific Search Space, USS), DCI 0_0 configured in a USS, DCI 1_2, DCI0_2, DCI 1_1, DCI 0_1.

It can be seen that, according to the embodiments of the present disclosure, the terminal may determine the size of the information field in the MC-DCI according to the configuration signaling, the predefined condition, and the size of the information field in the legacy DCI, and may further determine the information field value, thereby determining the information indicated by the information field.

Fig. 2 is a schematic flow chart diagram illustrating another information domain determining method according to an embodiment of the present disclosure. As shown in fig. 2, determining the size of at least one information field in the MC-DCI according to the configuration signaling includes:

in step S201, the size of the first information field in the MC-DCI is determined according to the information configured for the first information field by the first configuration signaling of the scheduling cell.

In one embodiment, the terminal may receive a first configuration signaling, e.g., RRC signaling, at the scheduling cell, and determine a size or a range of sizes of at least one information field in the MC-DCI according to the first configuration signaling. It should be noted that, in the related art, there is no first configuration signaling for configuring a size or a range of sizes of at least one information field in the MC-DCI. When the information configured by the first configuration signaling on the first information domain is the size range of the first information domain, the upper limit or the lower limit of the range can be determined to be the size of the first information domain in the MC-DCI.

For example, the first configuration signaling includes an information element (Information Element, IE) for indicating the size of at least one information field in the MC-DCI, and the information element is present in configuration information of each scheduled cell, and the terminal may determine the size of at least one information field in the MC-DCI according to the information element.

For example, taking the channel state information request (CSI (Channel State Information) request) information field as an example, the first configuration signaling is provided with an information element reportTriggerSize, and then the size of the CSI request information field may be determined according to the reportTriggerSize.

For example, taking the bandwidth part indication information field as an example, the first configuration signaling is provided with an information element nBWP, RRC, and the size of the bandwidth part indication information field may be determined by RRC according to nBWP.

Fig. 3 is a schematic flow chart diagram illustrating yet another information domain determining method according to an embodiment of the present disclosure. As shown in fig. 3, determining the size of at least one information field in the MC-DCI according to predefined conditions includes:

in step S301, the size of at least one information field in the MC-DCI is determined according to the association between the predefined condition and the number of bits of the reference cell in the cells that the MC-DCI can schedule and the predefined condition.

In one embodiment, the terminal may determine a reference cell among a plurality of scheduled cells that can be scheduled by the MC-DCI, and determine a predefined condition of the reference cell, and in case that the predefined condition of the reference cell has an association with a size of at least one information domain in the MC-DCI, determine the size of at least one information domain in the MC-DCI in the association according to the predefined condition of the reference cell.

For example, the predefined conditions include, but are not limited to: the DCI in the reference cell is configured based on the CSS and the DCI is configured based on the USS. Illustratively, for DCI format 0_0, the size of the FDRA (Frequency Domain Resource Assignment, frequency domain Resource allocation) domain is related to whether DCI format 0_0 is configured based on CSS or USS, if the DCI format 0_0 is configured based on USS, the size of the FDRA domain is related to the number of RBs (Resource blocks) and SCS (SubCarrier Spacing ) included in the uplink BWP, and if the DCI format 0_0 is configured based on CSS, the size of the FDRA domain is related to SCS only.

Fig. 4 is a schematic flow chart diagram illustrating yet another information domain determining method according to an embodiment of the present disclosure. As shown in fig. 4, determining a size for at least one information field in the MC-DCI according to the second configuration signaling includes:

In step S401, the size of the first information field in the MC-DCI is determined according to the information configured for the first information field by the second configuration signaling of the reference cell in the cells that can be scheduled by the MC-DCI.

In one embodiment, the terminal may determine a reference cell among a plurality of scheduled cells that can be scheduled by the MC-DCI, and receive second configuration signaling, such as RRC signaling, at the reference cell, and determine a size or a range of a size of at least one information field in the MC-DCI according to the second configuration signaling of the reference cell. When the information configured by the second configuration signaling on the first information domain is the size range of the first information domain, the upper limit or the lower limit of the range can be determined to be the size of the first information domain in the MC-DCI.

For example, the second configuration signaling includes an information element IE for indicating the size of at least one information field in the MC-DCI, and the information element is present in the configuration signaling of each scheduled cell, and the terminal may determine the size of at least one information field in the MC-DCI according to the information element.

For example, taking the CSI request information field as an example, the second configuration signaling is provided with an information element reportTriggerSize, and then the size of the CSI request information field may be determined according to the reportTriggerSize.

For example, taking the bandwidth part indication information field as an example, the second configuration signaling is provided with an information element nBWP, RRC, and the size of the bandwidth part indication information field may be determined by RRC according to nBWP.

Fig. 5 is a schematic flow chart diagram illustrating yet another information domain determining method according to an embodiment of the present disclosure. As shown in fig. 5, determining the size of at least one information field in the MC-DCI according to the size of at least one information field in the legacy downlink control information includes:

in step S501, the size of the first information field in the MC-DCI is determined to be equal to the size of the first information field in the legacy downlink control information.

In one embodiment, the terminal may determine the size of the first information field in the legacy DCI according to the configuration information of the network device, or determine the size of the first information field in the legacy DCI according to a predefined rule, and then may use the determined size of the first information field in the legacy DCI as the size of the first information field in the MC-DCI. That is, the same information domain size in legacy DCI and MC-DCI is determined.

Fig. 6 is a schematic flow chart diagram illustrating yet another information domain determining method according to an embodiment of the present disclosure. As shown in fig. 6, the determining the size of the first information field in the MC-DCI is equal to the size of the first information field in the legacy downlink control information includes:

In step S601, when the first information field in the legacy downlink control information is an information field with a fixed occupied bit number, the size of the first information field in the MC-DCI is determined to be equal to the size of the first information field in the legacy downlink control information.

In one embodiment, a first information field with a fixed number of occupied bits may be included in legacy DCI, for example, the size of the DCI format indication information field (Identifier for DCI formats) is constant to 1 bit, regardless of configuration signaling, conditions, etc. of the cell. In this case, the size of the first information field in the MC-DCI may be determined to be equal to the size of the first information field in legacy DCI.

For example, in the case where the size of the Identifier for DCI formats field in DCI format1_1 is constant, the size of the wide-portion indication information field in MC-DCI may be determined according to the size of the wide-portion indication information field in legacy DCI, for example, the size is constant to 1 bit.

For example, in the case where the size of HARQ process number (hybrid automatic repeat request process number) field in DCI format1_1 is constant, the size of CSI request information field in MC-DCI may be determined according to the size of CSI request information field in legacy DCI, for example, the size is constant to 6 bits.

In addition, in one embodiment, it may be further determined that the first information field in the legacy DCI can occupy a maximum value of the number of bits, and further determine that the size of the first information field in the MC-DCI is equal to the maximum value of the number of bits that the first information field in the legacy DCI can occupy.

For example, the size of the ZP CSI-RS trigger field in the DCI format 1_1 may be 0,1,2 bits, and then the maximum value of the bits occupied by the ZP CSI-RS trigger field in the DCI format 1_1 may be determined to be 2 bits, so as to determine the size of the ZP CSI-RS trigger field in the MC-DCI to be 2.

Fig. 7 is a schematic flow chart diagram illustrating yet another information domain determining method according to an embodiment of the present disclosure. As shown in fig. 7, the method further includes:

in step S701, the reference cell is determined according to configuration signaling of the network device; or determining the reference cell according to a predefined manner.

In one embodiment, the terminal may determine the reference cell in the cells that can be scheduled by the MC-DCI, and the manner of determining the reference cell may be determined according to configuration signaling (e.g., RRC signaling of the scheduling cell) of the network device, or may be determined according to a predefined manner, which is not limited in this disclosure.

The determination of the reference cell according to a predefined manner is exemplified below by several embodiments.

In one embodiment, the predefined manner includes at least one of:

determining an upper limit value of the size of a first information field of each scheduled cell in the at least one scheduled cell, and determining a scheduled cell corresponding to the maximum upper limit value as the reference cell;

Determining a lower limit value of the size of a first information field of each scheduled cell in the at least one scheduled cell, and determining a scheduled cell corresponding to the minimum lower limit value as the reference cell;

determining the identification of each scheduled cell in the at least one scheduled cell, and determining the scheduled cell with the largest identification as the reference cell;

and determining the identification of each scheduled cell in the at least one scheduled cell, and determining the scheduled cell with the minimum identification as the reference cell.

In one embodiment, when the size of the first information field in the MC-DCI needs to be determined, the terminal may first determine an upper limit value of the size of the first information field of the cell that the MC-DCI can schedule, where the upper limit value may be determined according to RRC signaling received in the cell that the MC-DCI can schedule. And further, the maximum upper limit value can be determined from the plurality of upper limit values, and a cell which can be scheduled by the MC DCI corresponding to the maximum upper limit value is determined as a reference cell.

For example, taking the CSI request information field as an example, the cells that can be scheduled by the MC DCI include cell #1 and cell #2, where the upper limit of the size of the CSI request information field of cell #1 is 4 and the upper limit of the size of the CSI request information field of cell #2 is 5, then it may be determined that cell #2 is the reference cell and that the size of the CSI request information field in the MC-DCI is equal to 5.

In one embodiment, when the size of the first information field in the MC-DCI needs to be determined, the terminal may first determine a lower limit value of the size of the first information field of the cell that the MC-DCI can schedule, where the lower limit value may be determined according to RRC signaling received in the cell that the MC-DCI can schedule. And further, the minimum lower limit value can be determined from the plurality of upper limit values, and a cell which can be scheduled by the MC DCI and corresponds to the minimum lower limit value is determined as a reference cell.

For example, taking the CSI request information field as an example, the cells that can be scheduled by the MC DCI include cell #1 and cell #2, where the lower limit of the size of the CSI request information field of cell #1 is 3 and the lower limit of the size of the CSI request information field of cell #2 is 4, then it may be determined that cell #1 is a reference cell and that the size of the CSI request information field in the MC-DCI is equal to 3.

In one embodiment, when the terminal needs to determine the size of the first information field in the MC-DCI, the terminal may determine the identity of the cell that can be scheduled by the MC-DCI first, and then may determine, from a plurality of upper limit values, the cell with the largest identity as the reference cell.

For example, taking the CSI request information field as an example, the cells that can be scheduled by the MC DCI include cell #1 and cell #2, where the identifier of cell #1 is 1, the identifier of cell #2 is 2, where identifier 2 is the largest, then it may be determined that cell #2 is the reference cell, and it is determined that the CSI request information field in the MC-DCI is equal to the CSI request information field in cell # 2.

In one embodiment, when the terminal needs to determine the size of the first information field in the MC-DCI, the terminal may first determine the identity of the scheduling cell that the MC-DCI can schedule, and then may determine, from a plurality of upper limit values, the cell with the smallest identity as the reference cell.

For example, taking the CSI request information field as an example, the cells that can be scheduled by the MC DCI include cell #1 and cell #2, where the identifier of cell #1 is 1, the identifier of cell #2 is 2, where the identifier 1 is the smallest, then it may be determined that cell #1 is the reference cell, and it is determined that the CSI request information field in the MC-DCI is equal to the CSI request information field in cell #1 in number of bits.

In one embodiment, the indication value of the first information domain in the MC-DCI is not expected by the terminal to be greater than an upper limit value of the indication value of the first information domain configured by each of the scheduled cells.

Of course, it is still possible for the network device to send the MC-DCI to the terminal, and the first indication value is greater than the upper limit value of the indication value of the first information field configured by the one or more scheduled cells, in which case the indication of the first information field in the MC-DCI may be wrong for the scheduled cell, so that this situation may be determined as an error case (error case), in which case the indication of the scheduled cell may be selected not according to the first information field in the MC-DCI, and this situation may also be reported to the network device.

Fig. 8 is a schematic flow chart diagram illustrating a method of cell determination according to an embodiment of the present disclosure. The cell determining method shown in the embodiment may be performed by a terminal, where the terminal includes, but is not limited to, a mobile phone, a tablet computer, a wearable device, a sensor, an internet of things device, and other communication apparatuses. The terminal may communicate with network devices including, but not limited to, network devices in 4G, 5G, 6G, etc., communication systems, e.g., base stations, core networks, etc.

As shown in fig. 8, the cell determination method may include the steps of:

in step S801, one or more cells scheduled by a first information field in MC-DCI are determined according to bit information in downlink control information MC-DCI for scheduling a plurality of cells.

In one embodiment, the terminal may receive the MC-DCI in the scheduling cell, where the cell scheduled by the MC-DCI may be referred to as a scheduled cell, which refers to all or part of all cells that can be scheduled by the MC-DCI, where the cell that can be scheduled by the MC-DCI may be determined according to configuration information of the network device, or may be determined according to a predefined rule. At least one field (field) is set in the MC-DCI, where the indication information of the first field in the MC-DCI is used to schedule one or more cells (for example, the first field in the MC-DCI is only used to schedule one cell), that is, determining one or more cells scheduled by the first field in the MC-DCI in this embodiment refers to determining one or more cells actually scheduled by the MC-DCI at the same time, and in this case, the manner in which the MC-DCI schedules multiple cells may be referred to as Type-1C. The first information field does not refer specifically to a certain information field but to any one of the at least one information field.

Since one DCI is used only for scheduling a cell in which the DCI is received in the related art, a cell to which the DCI is scheduled is not determined in a specific manner. In this embodiment, however, the MC-DCI is capable of scheduling a plurality of cells, and the first information field is used to schedule one or more of the cells that the MC-DCI is capable of scheduling, then it is necessary to determine which one or more of the cells to be scheduled is specifically used to schedule the first information field. In addition, the first information field in the MC-DCI is used to schedule one or more of the cells that can be scheduled because only a portion of the cells need to be scheduled by the first information field, rather than by each information field, in some time ranges.

According to the embodiment of the disclosure, the terminal can determine one or more cells scheduled by the first information field in the MC-DCI according to the bit information in the MC-DCI, so as to accurately determine that the first information field in the MC-DCI is particularly used for scheduling the cells in the scheduled cells.

In one embodiment, the bit information is consecutive n bits in the first information field of the MC-DCI, where n is a positive integer. For example, the bit information is the first bit to the nth bit in the first information field of the MC-DCI, or the last bit to the nth last bit in the first information field of the MC-DCI.

For example, n is 2, when the bit information is the first bit to the n-th bit in the first information field of the MC-DCI, one or more cells scheduled by the first information field in the MC-DCI may be determined according to the first 2 bits of the first information field in the MC-DCI;

for example, n is 3, and when the bit information is from the last bit to the n-th bit in the first information field of the MC-DCI, then the one or more cells scheduled by the first information field in the MC-DCI may be determined according to the last bit to the 3-th bit in the first information field of the MC-DCI.

Fig. 9 is a schematic flow chart diagram illustrating another cell determination method according to an embodiment of the present disclosure. As shown in fig. 9, determining one or more cells scheduled by an information field in MC-DCI according to bit information in the MC-DCI includes:

in step S901, one or more cells scheduled by an information field in the MC-DCI are determined according to an association between the value of the bit information and the cell and the value of the bit information.

In one embodiment, the terminal may store in advance an association relationship between the value of the bit information and the cell, and further in receiving the MC-DCI, may determine the value of the bit information in the MC-DCI, and further determine, in the association relationship, that the cell corresponding to the value of the bit information is one or more cells scheduled by the information domain in the MC-DCI.

For example, to determine one or more cells scheduled by a first information field in the MC-DCI from the first 2 bits in the MC-DCI, the relationship between the values of the first 2 bits in the MC-DCI and the cells scheduled by the first information field in the MC-DCI is shown in table 1 below:

the first 2 bits in MC-DCI	First information domain scheduled cell
		00	Cell #1
01	Cell #3
		10	Cell #5
11	Cell #6

TABLE 1

Based on table 1, the terminal may determine that the first information field in the MC-DCI is used to schedule cell #1 when the value of the first 2 bits in the MC-DCI is 00; when the value of the first 2 bits in the MC-DCI is 01, the first information field in the MC-DCI is used to schedule cell #3; when the value of the first 2 bits in the MC-DCI is 10, the first information field in the MC-DCI is used to schedule cell #5; when the value of the first 2 bits in the MC-DCI is 11, the first information field in the MC-DCI is used to schedule cell #6. The cells that the terminal can schedule are cell #1, cell #2, cell #3, cell #4, cell #5, and cell #6, and the cells that the terminal can schedule may be part of the cells that the terminal can schedule, for example, 4 cells such as cell #1, cell #3, cell #5, and cell #6 of the above 6 cells.

It will be appreciated that each element in table 1 is independent, and that these elements are illustratively listed in the same table, but do not represent that all elements in the table must exist simultaneously in accordance with what is shown in the table. Wherein the value of each element is independent of any other element value in table 1. It will be appreciated by those skilled in the art that the values of each element in Table 1 are a separate embodiment

In one embodiment, the association between the value of the bit information and the cell includes:

the positive correlation between the value of the bit information and the identity of the cell, for example, the larger the value of the bit information, the larger the identity of the first information field in the MC-DCI for scheduling the cell, for example, when the values of the first 2 bits in the MC-DCI are 00, 01, 10, 11, respectively indicate that the first information field in the MC-DCI is used for scheduling cell #1 identified as 1, cell #2 identified as 3, cell #3 identified as 5, and cell #4 identified as 6;

the negative correlation between the value of the bit information and the identity of the cell, e.g. the larger the value of the bit information, the smaller the identity of the first information field in the MC-DCI for scheduling the cell, e.g. the first 2 bits in the MC-DCI have values 00, 01, 10, 11, respectively indicating that the first information field in the MC-DCI is used for scheduling cell #4 identified as 4, cell #3 identified as 3, cell #2 identified as 2, cell #1 identified as 1.

In one embodiment, in addition to the above embodiment determining the one or more cells scheduled by the first information field in the MC-DCI according to bit information in the MC-DCI, the one or more cells scheduled by the first information field in the MC-DCI may be determined according to a predefined manner. For example, the identity of the cell being scheduled may be determined, the cell with the largest identity being the cell scheduled by the first information field in the MC-DCI, or the cell with the smallest identity being the cell scheduled by the first information field in the MC-DCI.

Fig. 10 is a schematic flow chart diagram illustrating a method of information domain determination according to an embodiment of the present disclosure. The information domain determining method shown in the embodiment may be executed by a network device, where the network device may communicate with a terminal, where the network device includes, but is not limited to, a base station in a communication system such as a 4G base station, a 5G base station, and a 6G base station, and the terminal includes, but is not limited to, a mobile phone, a tablet computer, a wearable device, a sensor, and a communication apparatus such as an internet of things device.

As shown in fig. 10, the information domain determining method may include the steps of:

in step S1001, the size of at least one information field in downlink control information MC-DCI for scheduling a plurality of cells, which is transmitted to a terminal, is determined according to any one of the following information: configuration signaling; predefined conditions; the size of at least one information field in the legacy downlink control information sent to the terminal.

In one embodiment, the network may schedule cells to the terminals MC-DCI, where the cells scheduled by the MC-DCI may be referred to as the scheduled cells, which refers to all or part of all the cells that can be scheduled by the MC-DCI, where the cells that can be scheduled by the MC-DCI may be determined according to configuration information of the network device, or may be determined according to predefined rules, which is not limited in this disclosure. The cell scheduled by the MC-DCI, namely the cell to be scheduled, is the cell actually scheduled by the MC-DCI, and the cell which can be scheduled by the MC-DCI is used for representing the capacity range of the MC-DCI, and the cell to be scheduled belongs to the cell which can be scheduled by the MC-DCI.

Since one DCI is used to schedule only one cell in the related art, an information field (e.g., a value of the information field) in the DCI is only suitable for indicating for the one scheduled cell. For example, taking the bandwidth part indication this information field as an example, bandwidth part indication information in DCI in the related art may be used to indicate whether a scheduled cell switches bandwidth part BWP.

And, based on the present embodiment, the bandwidth part indication information field in the MC-DCI may be used to indicate whether all the scheduled cells switch BWP. In this process, the network device needs to determine the size of the information domain, and thus determine the information domain value, so as to know what information is specifically indicated by the information domain.

In one embodiment, the network device may send a first configuration signaling, e.g., radio resource control, RRC, signaling to the terminal at the scheduling cell, the size of at least one information field in the MC-DCI being determined according to the first configuration signaling. It should be noted that, in the related art, there is no first configuration signaling for configuring a size of at least one information field in the MC-DCI.

In one embodiment, the network device may determine a reference cell among a plurality of scheduled cells that can be scheduled by the MC-DCI, and send a second configuration signaling, such as RRC signaling, to the terminal in the reference cell, where the size of at least one information field in the MC-DCI is determined according to the second configuration signaling of the reference cell, or where a predefined condition of the reference cell has an association with the size of at least one information field in the MC-DCI, the size of at least one information field in the MC-DCI may be determined in the association according to the predefined condition of the reference cell.

In one embodiment, the network device may determine the size for at least one information field in the MC-DCI according to the size of the at least one information field in the legacy DCI, e.g., regarding the size of the first information field in the legacy DCI as the size of the first information field in the MC-DCI.

Here, legacy DCI refers to DCI already specified in the related art, including but not limited to DCI1_0 configured by CSS, DCI 0_0 configured by CSS, DCI1_0 configured by USS, DCI 0_0 configured by USS, DCI 1_2, DCI 0_2, DCI 1_1, DCI 0_1.

It can be seen that according to the embodiments of the present disclosure, the network device may determine the size of the information field in the MC-DCI sent to the terminal according to the first configuration signaling sent to the terminal in the scheduling cell, the second configuration signaling sent to the terminal in the reference cell, the predefined condition of the second reference cell, and the size of the information field in the legacy DCI, and further may determine the information field value, thereby determining the information indicated by the information field.

It should be noted that, after determining the size of the first information field in the MC-DCI, the terminal may perform different operations, and the network device may perform the operations corresponding to the operations after determining the size of the first information field in the MC-DCI. For example, after determining the size of the first information field in the MC-DCI, the terminal may parse the first information field according to the size of the first information field in the MC-DCI, and after determining the size of the first information field in the MC-DCI, the network device may configure the first information field in the MC-DCI according to the size of the first information field in the MC-DCI, so that the first information field can indicate the required information.

In one embodiment, determining the size of at least one information field in the MC-DCI according to the first configuration signaling comprises: and determining the size of the first information domain in the MC-DCI according to the information configured by the first configuration signaling on the first information domain.

The network device may send a first configuration signaling, e.g. RRC signaling, to the terminal at the scheduling cell, the size or the range of sizes of the at least one information field in the MC-DCI being determined according to the first configuration signaling. It should be noted that, in the related art, there is no first configuration signaling for configuring a size or a range of sizes of at least one information field in the MC-DCI. When the information configured by the first configuration signaling on the first information domain is the size range of the first information domain, the upper limit or the lower limit of the range can be determined to be the size of the first information domain in the MC-DCI.

For example, the first configuration signaling includes an information element IE for indicating a size of at least one information field in the MC-DCI, and the information element is present in the configuration signaling of each scheduled cell, and the terminal may determine the size of at least one information field in the MC-DCI according to the information element.

For example, taking the CSI request information field as an example, the first configuration signaling is provided with an information element reportTriggerSize, and then the size of the CSI request information field may be determined according to the reportTriggerSize.

In one embodiment, determining the size of at least one information field in the MC-DCI according to predefined conditions comprises: and determining the size of at least one information domain in the MC-DCI according to the association relation between the predefined condition and the bit number and the predefined condition.

The network device may determine a reference cell among a plurality of scheduled cells scheduled by the MC-DCI, and determine a predefined condition of the reference cell, and in case that the predefined condition of the reference cell has an association relationship with a size of at least one information field in the MC-DCI, may determine the size of the at least one information field in the MC-DCI in the association relationship according to the predefined condition of the reference cell.

For example, the predefined conditions include, but are not limited to: the DCI in the reference cell is configured based on the CSS and the DCI is configured based on the USS. Illustratively, for DCI format 0_0, the size of the FDRA domain is related to whether DCI format 0_0 is configured based on CSS or USS, if the DCI format 0_0 is configured based on USS, the size of the FDRA domain is related to the number of RBs and SCS included in the uplink BWP, and if the DCI format 0_0 is configured based on CSS, the size of the FDRA domain is related to SCS only.

In one embodiment, determining the size for at least one information field in the MC-DCI according to the second configuration signaling comprises: and determining the size of the first information domain in the MC-DCI according to the information configured by the second configuration signaling on the first information domain.

The network device may determine a reference cell among a plurality of scheduled cells scheduled by the MC-DCI, and send a second configuration signaling, e.g., RRC signaling, to the terminal at the reference cell, and determine a size or a range of sizes of at least one information field in the MC-DCI according to the second configuration signaling of the reference cell. When the information configured by the second configuration signaling on the first information domain is the size range of the first information domain, the upper limit or the lower limit of the range can be determined to be the size of the first information domain in the MC-DCI.

In one embodiment, determining the size of the at least one information field in the MC-DCI according to the size of the at least one information field in the legacy downlink control information comprises: and determining the size of the first information field in the MC-DCI to be equal to the size of the first information field in the traditional downlink control information.

The network device may determine the size of the first information field in the legacy DCI according to the configuration information sent to the terminal, or determine the size of the first information field in the legacy DCI according to a predefined rule, and then may use the determined size of the first information field in the legacy DCI as the size of the first information field in the MC-DCI. That is, the same information domain size in legacy DCI and MC-DCI is determined.

In one embodiment, the determining the size of the first information field in the MC-DCI is equal to the size of the first information field in the legacy downlink control information includes: and when the first information domain in the traditional downlink control information is an information domain with fixed occupied bit number, determining the size of the first information domain in the MC-DCI, wherein the size of the first information domain is equal to the size of the first information domain in the traditional downlink control information.

The legacy DCI may include a first information field with a fixed number of occupied bits, for example, the size of the DCI format indication information field is constant to 1 bit, regardless of configuration signaling, conditions, etc. of the cell. In this case, the size of the first information field in the MC-DCI may be determined to be equal to the size of the first information field in legacy DCI.

For example, in the case where the size of the HARQ process number field in DCI format1_1 is constant, the size of the CSI request information field in MC-DCI may be determined according to the size of the CSI request information field in legacy DCI, for example, the size is constant to 6 bits.

For example, the size of the ZP CSI-RS trigger field in DCI format1_1 may be 0,1,2 bits, and then the maximum value of the bits occupied by the ZP CSI-RS trigger field in DCI format1_1 may be determined to be 2 bits, and further the size of the ZP CSI-RS trigger field in MC-DCI may be determined to be equal to 2.

In one embodiment, the method further comprises: the terminal is instructed to determine the reference cell through configuration signaling; or determining the reference cell according to a predefined manner.

In one embodiment, the network device may determine the reference cell in the cell scheduled by the MC-DCI, i.e. the scheduled cell, and the manner of determining the reference cell may be determined according to configuration signaling (e.g. RRC signaling of the scheduling cell) sent to the terminal, or may be determined according to a predefined manner, which is not limited in this disclosure.

In one embodiment, the predefined manner includes at least one of:

In one embodiment, when the network device needs to determine the size of the first information domain in the MC-DCI, the network device may first determine an upper limit value of the size of the first information domain of the cell that the MC-DCI can schedule, where the upper limit value may be determined according to RRC signaling sent to the terminal in the cell that the MC-DCI can schedule. And further, the maximum upper limit value can be determined from the plurality of upper limit values, and a cell which can be scheduled by the MC DCI corresponding to the maximum upper limit value is determined as a reference cell.

In one embodiment, when the network device needs to determine the size of the first information domain in the MC-DCI, the network device may first determine a lower limit value of the size of the first information domain of the cell that can be scheduled by the MC DCI, where the lower limit value may be determined according to RRC signaling sent to the terminal that can be scheduled by the MC DCI. And further, the minimum lower limit value can be determined from the plurality of upper limit values, and a cell which can be scheduled by the MC DCI and corresponds to the minimum lower limit value is determined as a reference cell.

In one embodiment, when the network device needs to determine the size of the first information field in the MC-DCI, the network device may determine the identity of the cell that can be scheduled by the MC-DCI first, and then may determine, from multiple upper limit values, the cell with the largest identity as the reference cell.

In one embodiment, when the network device needs to determine the size of the first information field in the MC-DCI, the network device may determine first the identity of the scheduling cell that the MC-DCI can schedule, and then may determine, from a plurality of upper limit values, the cell with the smallest identity as the reference cell.

The cell determining method shown in the embodiment may be performed by a network device, where the network device may communicate with a terminal, where the network device includes, but is not limited to, a base station in a communication system such as a 4G base station, a 5G base station, and a 6G base station, and the terminal includes, but is not limited to, a mobile phone, a tablet computer, a wearable device, a sensor, and a communication apparatus such as an internet of things device.

In one embodiment, the network device may send the MC-DCI to the terminal in the scheduling cell, where the cell scheduled by the MC-DCI may be referred to as a scheduled cell, which refers to all or part of all the cells that can be scheduled by the MC-DCI, where the cell that can be scheduled by the MC-DCI may be determined according to configuration information of the network device, or may be determined according to a predefined rule. At least one field (field) is set in the MC-DCI, where the indication information of the first field in the MC-DCI is used to schedule one or more cells (for example, the first field in the MC-DCI is only used to schedule one cell), that is, determining one or more cells scheduled by the first field in the MC-DCI in this embodiment refers to determining one or more cells actually scheduled by the MC-DCI, in which case, the manner in which the MC-DCI schedules multiple cells may be referred to as Type-1C. The first information field does not refer specifically to a certain information field but to any one of the at least one information field.

According to the embodiment of the disclosure, the network device can instruct the terminal to determine one or more cells scheduled by the first information domain in the MC-DCI through bit information in the MC-DCI, so that the terminal accurately determines that the first information domain in the MC-DCI is particularly used for scheduling cells in the scheduled cells.

For example, setting n to 2, and when the bit information is the first bit to the nth bit in the first information field of the MC-DCI, indicating one or more cells scheduled by the first information field in the MC-DCI through the first 2 bits of the first information field in the MC-DCI;

The network device may store the association between the value of the bit information and the cell in advance, and further determine, when the indication is performed, a cell scheduled by the information domain in the MC-DCI, and determine, in the association, a target value corresponding to the cell scheduled by the information domain in the MC-DCI, set the bit information in the MC-DC equal to the determined target value, and send the MC-DCI to the terminal, so that the terminal may determine the value of the bit information in the MC-DCI, and further determine, in the association, that the cell corresponding to the value of the bit information is one or more cells scheduled by the information domain in the MC-DCI.
