In some embodiments, step S202 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

In some embodiments, reference may be made to alternative implementations described before or after the description corresponding to fig. 2.

In some embodiments, the network device may send downlink control information (e.g., MC-DCI, multi cell scheduling Downlink Control Information) to the terminal for scheduling the plurality of cells.

In contrast to conventional downlink control information (legacy DCI), one MC-DCI can be used to schedule a plurality of cells (also can be used to schedule one cell among a plurality of cells), and one legacy DCI can only be used to schedule one cell.

For example, in some embodiments, the format (format) of the MC-DCI may be different from the format of the legacy DCI, e.g., the format of the MC-DCI includes, but is not limited to, DCI 0_3, DCI 1_3, the format of the legacy DCI includes, but is not limited to, DCI 0_0, DCI 0_1, DCI 1_0, DCI 1_1, DCI 2_0, DCI 2_1.

The downlink control information may include at least one information field (field, which may also be referred to as a domain), for example, a frequency domain resource allocation (FDRA, frequency Domain Resource Assignment) information field.

In some embodiments, the value of the FDRA information domain may be invalid (invalid), where the frequency domain resource determined based on the FDRA information domain is an invalid frequency domain resource under a condition that the value of the FDRA information domain is invalid, for example, the frequency domain resource is before a frequency domain range corresponding to a current BWP (BandWidth Part), and illustratively, the case of the invalid FDRA value includes at least one of:

in the case where the resource allocation Type is Type0 (Type 0), the value of all bits in the FDRA information domain is 0 (all 0for Type 0);

in the case where the resource allocation Type is Type1 (Type 1), the value of all bits in the FDRA information domain is 1 (all 1for Type 1);

in the case where the resource allocation Type is dynamic (dynamic), the value of all bits in the FDRA information domain is 0 if the corresponding resource allocation Type is Type0 (Type 0), and the value of all bits in the FDRA information domain is 1 if the corresponding resource allocation Type is Type1 (Type 1).

In the case where the resource allocation Type is Type2 (Type 2), if the corresponding SCS (Sub-Carrier Spacing) parameter μ=1, the value of all bits in the fdra information domain is 0. If the corresponding SCS parameter μ=0, the value of all bits in the fdra information domain is 1. Illustratively, μ=0 corresponds to SCS at 15kHz and μ=1 corresponds to SCS at 30 kHz.

For legacy DCI, for example, in a case where the value of the FDRA information field corresponding to DCI 1_1 is invalid and the single-shot hybrid automatic repeat request acknowledgement (one shot HARQ (Hybrid Automatic Repeat reQuest) ACK) information field does not exist or the value is 0, the scenario corresponding to the condition may be that the DCI carries secondary cell dormancy (Scell dorma) indication information, and multiple information fields in the DCI may be re-plowed to be used for indicating the dormancy state of the secondary cell.

In the case of introducing the MC-DCI, the Type of the FDRA information field may be Type-2 (of course, the name of the Type is not limited thereto and may be named by other names). Wherein, for the Type-2 information field, the MC-DCI includes at least one Type information field, and a single information field in the at least one Type information field is used to indicate related information of a single scheduled cell.

For example, for an FDRA information field, the MC-DCI may contain multiple FDRA information fields, a single FDRA information field to indicate resource allocation information for a single cell. For example, the MC-DCI includes 4 FDRA information fields, and is used to schedule 4 cells: cell#1, cell#2, cell#3, cell#4. The first FDRA information field may be used to indicate resource allocation information for Cell #1, the second FDRA information field may be used to indicate resource allocation information for Cell #2, the third FDRA information field may be used to indicate resource allocation information for Cell #3, and the fourth FDRA information field may be used to indicate resource allocation information for Cell #4.

In the case that the MC-DCI contains an invalid FDRA information field value (for example, the value of a part of the FDRA information field is invalid or the value of all the FDRA information fields is invalid), and the one shot HARQ-ACK information field does not exist or has a value of 0, the corresponding scenario may carry the secondary cell dormancy indication information for the MC-DCI, and may correspond to another scenario: the cell is not scheduled. For example, the value of the second FDRA information field in the 4 FDRA information fields is invalid, and the one shot HARQ-ACK information field does not exist or has a value of 0, and the scenario corresponding to the condition may be that cell#2 is not scheduled, or may be that MC-DCI carries secondary Cell dormancy indication information. And when the condition only comprises that the MC-DCI contains invalid FDRA information threshold values, the scene corresponding to the condition can comprise the following three types: the MC-DCI carries secondary cell dormancy indication information and a hybrid automatic repeat request acknowledgement (Type-3 HRAQ-ACK) of cell non-scheduled Type 3.

In some embodiments, under the condition that the value of the FDRA information field is invalid, other scenarios, such as type 3 hybrid automatic repeat request acknowledgement, may be corresponding to the two scenarios, where the value of one shot HARQ-ACK is 1; such as Type 1 and/or Type 2codebook retransmissions (e.g., type 1&type 2codebook retransmission), in which case the value of the HRAQ-ACK retransmission indication information field is 1.

Therefore, after the MC-DCI is introduced, under the condition that the MC-DCI contains invalid FDRA information threshold values, the corresponding scenes are relatively more, and the technical problem that the terminal is in misoperation due to incapability of distinguishing the scenes can be caused.

It should be noted that, for the codebook retransmission scenario of type 1 and/or type 2, the HRAQ-ACK retransmission indication information field may explicitly distinguish the scenario from other scenarios, so the embodiments of the present disclosure mainly describe how to distinguish the three scenarios of MC-DCI carrying secondary cell dormancy indication information, cell non-scheduling, and type 3 hybrid automatic retransmission acknowledgement.

In a first aspect, embodiments of the present disclosure provide an information receiving method. Fig. 3 is a schematic flow chart diagram illustrating an information receiving method according to an embodiment of the present disclosure. The information receiving method shown in the present embodiment may be performed by a terminal.

As shown in fig. 3, the information receiving method may include the steps of:

in step S301, downlink control information (for example, MC-DCI) sent by a network device is received, where the downlink control information is used to schedule a plurality of cells;

in step S302, a scenario is determined according to the first information, where the downlink control information includes an invalid frequency domain resource allocation FDRA information threshold.

It should be noted that the embodiment shown in fig. 3 may be implemented independently or in combination with at least one other embodiment in the disclosure, and specifically may be selected as needed, which is not limited by the disclosure.

In some embodiments, after receiving the downlink control information, the terminal may determine whether the downlink control information includes an invalid FDRA information domain value, and when determining that a value of one FDRA information domain in the downlink control information is invalid, or determining that values of a plurality of FDRA information domains in the downlink control information are invalid, may determine that the downlink control information includes an invalid FDRA information domain value.

According to the embodiment of the disclosure, under the condition that the downlink control information comprises the invalid FDRA information threshold value, the terminal can determine the scene corresponding to the condition according to the first information, so that the terminal can accurately distinguish the scene corresponding to the condition, further execute subsequent operation based on the distinguished scene, and the technical problem that the terminal cannot distinguish the scene corresponding to the condition to perform misoperation is solved.

The details of the first information and how the scenes are distinguished based on the first information are described in the following embodiments, and will not be described in detail here.

In some embodiments, the first information includes at least one of:

at least one first information field value of a re-tillage (repurpose) in the information field corresponding to the reference cell in the downlink control information;

the invalid FDRA information threshold corresponds to the number of cells;

In some embodiments, the first information field includes at least one of:

a modulation coding strategy (Modulation and Coding Scheme, MCS) information field;

-a new data indication (New Data Indicator, NDI) information field;

redundancy version (Redundancy Version, RV) information fields;

hybrid automatic repeat request process number (HARQ process number) information field;

Antenna port (Antenna port) information field.

The demodulation reference signal sequence initializes (DMRS (Demodulation Reference Signal) sequence initialization) the information field.

In some embodiments, for the MCS information field, NDI information field, RV information field, it may be a Transport Block (TB) 1 information field or a TB2 information field.

In some embodiments, the Type of MCS information field, NDI information field, RV information field, HARQ process number information field may be Type-2.

In some embodiments, the type of DMRS sequence initialization information field may be type-1A (of course, the name of the type is not limited thereto and may be named by other names). Wherein, for the type-1A type information field, the downlink control information includes one type information field, and the one information field is used for scheduling all cells scheduled by the downlink control information.

In some embodiments, the Type of Antenna port information field may be Type-1A, or Type-2.

In some embodiments, the at least one first information field of the heavy tilling may include an MCS information field, an NDI information field, an RV information field, a HARQ process number information field, an Antenna port information field, and a DMRS sequence initialization information field.

In some embodiments, the at least one first information field of the heavy tilling may include an MCS information field, an NDI information field, an RV information field, a HARQ process number information field, and an Antenna port information field.

In some embodiments, the at least one first information field of the heavy tilling may include an MCS information field, an NDI information field, an RV information field, and a HARQ process number information field.

In some embodiments, the at least one first information field of the heavy tillage may include an MCS information field, an NDI information field, an RV information field, and a HARQ process number information field, wherein the first information field may further include an Antenna port information field when the Type of the Antenna port information field is Type-2, and the first information field does not include the Antenna port information field when the Type of the Antenna port information field is Type-1A.

It should be noted that, the heavy tillage described in the embodiments of the present disclosure refers to, for the information field of heavy tillage, the information field is not used to implement the original indication function, but is used to implement the new indication function after heavy tillage.

For example, the MCS information field is originally used to indicate a modulation and coding scheme, but is used to indicate a secondary cell sleep state after heavy tillage. For example, n bits occupied by the at least one first information field of the re-tillage are n bits, and then a sleep state of n secondary cells may be indicated, where a correspondence may exist between the n bits and the n secondary cells, where an ith bit in the n bits is used to indicate the sleep state of an ith secondary cell in the n secondary cells, for example, the ith bit is 0, is used to indicate that the secondary cell is in the sleep state, and the ith bit is 1, is used to indicate that the secondary cell is not in the sleep state, where i and n are positive integers, and i is less than or equal to n.

In some embodiments, the information receiving method further comprises: and when the downlink control information is determined to carry the sleep indication information of the auxiliary cell, determining the sleep state of the auxiliary cell according to at least one first information field of the corresponding reference cell in the downlink control information.

Based on the foregoing embodiment, under the condition that the downlink control information includes the invalid FDRA information domain value of the frequency domain resource allocation, there are three corresponding scenarios, namely, HARQ-ACK is acknowledged by hybrid automatic repeat request of type 3, the downlink control information carries the auxiliary cell dormancy indication information, and the cell is not scheduled. The operations subsequently performed by the terminal may be different for different scenarios therein, and thus the above-described technical problem of misoperation may occur.

For example, taking two scenarios that the downlink control information carries the sleep indication information of the secondary cell and the cell is not scheduled as an example. In the case where the scenario is that the cell is not scheduled, the operation performed by the terminal may include not communicating for the scheduled cell; in the case that the scenario is that the downlink control information carries the sleep indication information of the secondary cell, the operation performed by the terminal may include determining the sleep state of the secondary cell according to at least one first information field of the secondary cell corresponding to the reference cell in the downlink control information, for example, n bits occupied by the at least one first information field of the secondary cell are occupied, and the terminal may determine the sleep state of the n secondary cells according to the n bits, that is, determine whether each secondary cell in the n secondary cells is in the sleep state.

In some embodiments, the reference cell comprises at least one of:

a primary cell Pcell;

cells of at least one of the cells corresponding to the invalid FDRA information threshold;

at least one cell for calculating blind detection information among cells actually scheduled by the downlink control information.

In some embodiments, the set of cells corresponding to the downlink control information may be a set of cells configured by cells that can be scheduled by the downlink control information. In some embodiments, the blind detection information includes at least one of: blind Decoding (BD), control channel elements (Control Channel Element, CCE).

In some embodiments, the reference cell may be one of the cells actually scheduled by the downlink control information or a plurality of the cells actually scheduled by the downlink control information. For example, when the reference cell is one of the cells actually scheduled by the downlink control information, the reference cell may be the cell with the smallest identifier (ID, the identifier may be referred to as index) among the cells actually scheduled by the downlink control information, or may be the cell with the largest identifier among the cells actually scheduled by the downlink control information.

In some embodiments, the reference cell may be one cell in a set of cells corresponding to the downlink control information, or a plurality of cells in the set of cells. For example, when the reference cell is one cell in the cell set, the cell may be the cell with the smallest identifier in the cell set, or may be the cell with the largest identifier in the cell set, which is not limited to this, and may be any cell with a corresponding identifier in the cell set.

In some embodiments, the reference cell may be one of the cells corresponding to the invalid FDRA information domain value or a plurality of the cells corresponding to the invalid FDRA information domain value. For example, when the reference cell is one of the cells corresponding to the invalid FDRA information domain value, the reference cell may be the cell with the smallest identification among the cells corresponding to the invalid FDRA information domain value; alternatively, it may be that the cell identified as the largest cell is identified for the cell for which the FDRA information domain value is invalid.

For example, 4 FDRA information fields, a first FDRA information field for indicating resource allocation information for Cell #1, a second FDRA information field for indicating resource allocation information for Cell #2, a third FDRA information field for indicating resource allocation information for Cell #3, and a fourth FDRA information field for indicating resource allocation information for Cell # 4. When the value of the first FDRA information field is invalid and the value of the third FDRA information field is invalid, the cells corresponding to the invalid FDRA information field values are Cell #1 and Cell #3, if the reference Cell is the Cell with the smallest identification number in the Cell corresponding to the invalid FDRA information field value, the reference Cell is Cell #1, and if the reference Cell is the Cell with the largest identification number in the Cell corresponding to the invalid FDRA information field value, the reference Cell is Cell #3. Of course, the reference cell is not limited to this, and the reference cell may be any identified cell among cells corresponding to the invalid FDRA information domain value.

In some embodiments, determining a scene from the first information includes: and determining that the scene corresponding to the condition is downlink control information carrying cell dormancy indication information or cell non-scheduling according to the first information, wherein the single-shot hybrid automatic repeat request confirmation indication information field in the downlink control information does not exist or has a value of 0.

For example, the terminal may analyze the FDRA information field and the single-shot hybrid automatic repeat request acknowledgement indication information field in the downlink control information first, and when it is determined that there are invalid FDRA information field values, and if the single-shot hybrid automatic repeat request acknowledgement indication information field does not exist or has a value of 0, the scenes corresponding to the conditions are only two: the downlink control information carries cell dormancy indication information and the cell is not scheduled, and the terminal can distinguish whether the scene corresponding to the condition specifically carries the cell dormancy indication information or the cell is not scheduled according to the first information.

In some embodiments, the information receiving method further comprises: the scene is one of the hybrid automatic repeat request acknowledgement and the downlink control information of the type 3 carrying the auxiliary cell dormancy indication information, and the hybrid automatic repeat request acknowledgement or the downlink control information of the type 3 carrying the auxiliary cell dormancy indication information is determined according to a single-shot hybrid automatic repeat request acknowledgement indication information field in the downlink control information.

For example, the terminal may analyze the FDRA information field in the downlink control information first, and when determining that there are invalid FDRA information field values, the conditions correspond to three scenarios: the type 3 hybrid automatic repeat request acknowledgement and downlink control information carry auxiliary cell dormancy indication information, and the cells are not scheduled. Further, the terminal may attempt to distinguish between the scenarios according to the first information, and when determining that the cell is not scheduled according to the first information, the terminal may not need to further distinguish, or may not parse the one-shot hybrid automatic repeat request acknowledgement indication information field; when the first scenario includes one of the type 3 harq acknowledgement and the downlink control information carrying the secondary cell dormancy indication information, then a further scenario distinction is required, and the terminal may distinguish whether the scenario is specifically the type 3 harq acknowledgement or the downlink control information carries the secondary cell dormancy indication information according to a single-shot harq acknowledgement indication information field in the downlink control information.

It can be seen that, in some embodiments, the conditions described in the embodiments of the present disclosure are only that the downlink control information includes an invalid FDRA information field value, and in other embodiments, the conditions described in the embodiments of the present disclosure may be that the downlink control information includes an invalid FDRA information field value, and that the single-shot hybrid automatic repeat request acknowledgement indication information field in the downlink control information does not exist or has a value of 0.

The scene corresponding to the condition according to the first information determination is exemplarily described below by several embodiments.

In some embodiments, determining the scene from the first information includes at least one of:

the value of at least one information field is a first value, and the fact that the cell is not scheduled is determined;

the value of at least one information field is a second value, and it is determined that the downlink control information carries the auxiliary cell dormancy indication information, or is one of type 3 hybrid automatic repeat request acknowledgement and the downlink control information carries the auxiliary cell dormancy indication information.

In some embodiments, when the first information is a value of at least one other information domain other than the FDRA information domain in the information domain of the corresponding reference cell in the downlink control information, the value of the at least one information domain may be determined according to all bits in the at least one first information domain.

For example, in the case that the downlink control information includes an invalid FDRA information field value, and the single-shot hybrid automatic repeat request acknowledgement indicator field in the downlink control information does not exist or has a value of 0, the corresponding scenario may include that the downlink control information carries one of cell dormancy indicator information and cell non-scheduling. Under the condition that the value of at least one information field is a first value, the terminal can distinguish a scene, particularly a cell, from not being scheduled; under the condition that the value of at least one information field is the second value, the terminal can distinguish the scene, particularly that the downlink control information carries the cell dormancy indication information.

It should be noted that the first value and the second value may be two different values, and the first value may be the same or different in different embodiments, and the second value may be the same or different in different embodiments, for example, the first value may be 0, and the second value may be 1, which is not limited to this.

For example, where the downlink control information includes an invalid FDRA information field value, the corresponding scenario may include one of downlink control information carrying cell dormancy indication information, cell non-scheduling, type 3 hybrid automatic repeat request acknowledgement. Under the condition that the value of at least one information field is a first value, the terminal can distinguish a scene, particularly a cell, from not being scheduled; and under the condition that the value of at least one information field is a second value, the terminal can distinguish that the scene is one of the hybrid automatic repeat request acknowledgement of the type 3 and the downlink control information carries the sleep indication information of the auxiliary cell.

In this case, the terminal may further determine that the downlink control information carries secondary cell dormancy indication information according to the single-shot hybrid automatic repeat request acknowledgement indication information field distinguishing scenario in the downlink control information, for example, under the condition that the single-shot hybrid automatic repeat request acknowledgement indication information field does not exist or has a value of 0, for example, under the condition that the single-shot hybrid automatic repeat request acknowledgement indication information field exists and has a value of 1, and may determine type 3 hybrid automatic repeat request acknowledgement.

determining that the cell is not scheduled, with the value of at least one bit in the at least one first information field being a first value;

the value of at least one bit in the at least one first information field is a second value, and it is determined that the downlink control information carries secondary cell dormancy indication information, or is one of type 3 hybrid automatic repeat request acknowledgement and downlink control information carries secondary cell dormancy indication information.

For example, in the case that the downlink control information includes an invalid FDRA information field value, and the single-shot hybrid automatic repeat request acknowledgement indicator field in the downlink control information does not exist or has a value of 0, the corresponding scenario may include that the downlink control information carries one of cell dormancy indicator information and cell non-scheduling. The terminal can distinguish a scene, particularly a cell, from being unscheduled under the condition that the value of at least one bit in at least one first information field is a first value; the terminal may distinguish that the scenario, specifically the downlink control information, carries cell dormancy indication information in case that the value of at least one bit in at least one first information field is a second value.

For example, where the downlink control information includes an invalid FDRA information field value, the corresponding scenario may include one of downlink control information carrying cell dormancy indication information, cell non-scheduling, type 3 hybrid automatic repeat request acknowledgement. The terminal can distinguish a scene, particularly a cell, from being unscheduled under the condition that the value of at least one bit in at least one first information field is a first value; the terminal may distinguish between a hybrid automatic repeat request acknowledgement of type 3 and a downlink control information carrying one of the secondary cell dormancy indication information in case the value of at least one bit in the at least one first information field is a second value.

In some embodiments, the at least one bit in the at least one first information field in the corresponding reference cell in the downlink control information may be one bit or a plurality of bits in the bits occupied by the at least one first information field in the corresponding reference cell in the downlink control information. When at least one bit in the at least one first information field corresponding to the reference cell in the downlink control information is one bit in the bits occupied by the at least one first information field corresponding to the reference cell in the downlink control information, the bit may be any one bit in the bits occupied by the at least one first information field corresponding to the reference cell in the downlink control information, for example, may be the first bit, or may be the last bit, and of course, may also be a bit between the first bit and the last bit.

For example, when the bit is the first bit in the bits occupied by at least one first information field in the corresponding reference cell in the downlink control information, the terminal may perform scene discrimination by analyzing the first bit in the bits occupied by at least one first information field. Because the at least one first information field in the reference cell is re-ploughed to determine the sleep state of the secondary cell under the condition that the scene is that the downlink control information carries the sleep indication information of the secondary cell, the terminal needs to analyze the bit after the first bit to determine the sleep state of the secondary cell, and the terminal can determine that the reference cell is not scheduled under the condition that the scene is that the cell is not scheduled, so that the bit after the first bit does not need to be further analyzed, thereby being beneficial to saving the cost.

For example, when the bit is the last bit in the bits occupied by at least one first information field in the corresponding reference cell in the downlink control information, the terminal may perform scene discrimination by parsing the first bit in the bits occupied by at least one first information field. When the scene is that the downlink control information carries the sleep indication information of the auxiliary cell, at least one first information domain in the reference cell is re-cultivated to determine the sleep state of the auxiliary cell, and when the at least one first information domain in the reference cell is re-cultivated to determine the sleep state of the auxiliary cell, an association relationship can exist between the bit occupied by the at least one first information domain in the reference cell and the auxiliary cell, the association relationship is generally associated with the auxiliary cell from the first bit of the bit occupied by the at least one first information domain, in this case, the scene is distinguished by the last bit in the bits occupied by the at least one first information domain, the association relationship between the bit before the last bit and the auxiliary cell can be not necessarily adjusted, and the overhead of adjusting the mapping relationship is beneficial to reducing.

the newly defined information field indicates a second value, and it is determined that the downlink control information carries secondary cell dormancy indication information, or one of type 3 hybrid automatic repeat request acknowledgement and downlink control information carries secondary cell dormancy indication information.

For example, in the case that the downlink control information includes an invalid FDRA information field value, and the single-shot hybrid automatic repeat request acknowledgement indicator field in the downlink control information does not exist or has a value of 0, the corresponding scenario may include that the downlink control information carries one of cell dormancy indicator information and cell non-scheduling. Under the condition that the newly defined information field indicates the first value, the terminal can distinguish the scene, particularly that the cell is not scheduled; under the condition that the newly defined information field indicates the second value, the terminal can distinguish that the scene is that the downlink control information carries the cell dormancy indication information.

It should be noted that the newly defined information field may occupy one or more bits, for example, in the case of occupying one bit, the first value may be 0, and the second value may be 1, which is not limited thereto.

For example, where the downlink control information includes an invalid FDRA information field value, the corresponding scenario may include one of downlink control information carrying cell dormancy indication information, cell non-scheduling, type 3 hybrid automatic repeat request acknowledgement. Under the condition that the newly defined information field indicates the first value, the terminal can distinguish the scene, particularly that the cell is not scheduled; and under the condition that the newly defined information field indicates the second value, the terminal can distinguish that the scene is one of the hybrid automatic repeat request acknowledgement of the type 3 and the downlink control information carrying the auxiliary cell dormancy indication information.

the type of at least one other information field is a first type, and the cell is determined not to be scheduled;

The type of the at least one other information field is a second type, and it is determined that the downlink control information carries the secondary cell dormancy indication information, or is one of a type 3 hybrid automatic repeat request acknowledgement and the downlink control information carries the secondary cell dormancy indication information.

For example, in the case that the downlink control information includes an invalid FDRA information field value, and the single-shot hybrid automatic repeat request acknowledgement indicator field in the downlink control information does not exist or has a value of 0, the corresponding scenario may include that the downlink control information carries one of cell dormancy indicator information and cell non-scheduling. The terminal can distinguish a scene, particularly a cell, from being unscheduled under the condition that the type of at least one other information field is the first type; and under the condition that the type of at least one other information field is the second type, the terminal can distinguish the scene, particularly that the downlink control information carries the cell dormancy indication information.

It should be noted that the at least one other information field may include one information field or include a plurality of information fields. For example, the at least one other information field includes an information field that is not limited to the Antenna port information field, HARQ process number information field, and the like. The first type and the second type include, but are not limited to, type-1A, type-1B, type-1C, type-2, type-3. Wherein, for the type-1B information field, the downlink control information may include one type information field, which may be used for indicating an index of an information combination of at least one scheduled cell; for a type-3 information field, the downlink control information may include one or more of the type information fields, which may be determined as one of type-1A, type-2 by a predefined or network device configured manner.

For example, where the downlink control information includes an invalid FDRA information field value, the corresponding scenario may include one of downlink control information carrying cell dormancy indication information, cell non-scheduling, type 3 hybrid automatic repeat request acknowledgement. The terminal can distinguish a scene, particularly a cell, from being unscheduled under the condition that the type of at least one other information field is the first type; and under the condition that the type of at least one other information field is the second type, the terminal can distinguish that the scene is one of the hybrid automatic retransmission acknowledgement of the type 3 and the downlink control information carries the sleep indication information of the auxiliary cell.

In some embodiments, determining a scene from the first information includes:

And determining that the value of the FDRA information field corresponding to the reference cell in the downlink control information is invalid, and determining that the downlink control information carries the auxiliary cell dormancy indication information, or is one of the type 3 hybrid automatic repeat request acknowledgement and the downlink control information carries the auxiliary cell dormancy indication information.

For example, in the case that the downlink control information includes an invalid FDRA information field value, and the single-shot hybrid automatic repeat request acknowledgement indicator field in the downlink control information does not exist or has a value of 0, the corresponding scenario may include that the downlink control information carries one of cell dormancy indicator information and cell non-scheduling. The terminal can distinguish the scenes according to the value of the FDRA information field of the reference cell, wherein the terminal can determine that the scenes, particularly the downlink control information, carry the cell dormancy indication information under the condition that the value of the FDRA information field of the reference cell is invalid. It should be noted that, the rule for distinguishing the scenario is predetermined (for example, a protocol is agreed or configured by a network), and when the single-shot hybrid automatic repeat request acknowledgement indicator information field does not exist or has a value of 0 and the value of the FDRA information field of the reference cell is invalid, the terminal determines that the scenario is specifically that the downlink control information carries the cell dormancy indicator information, and does not distinguish the scenario according to the value of the FDRA information field of the other cell.

For example, where the downlink control information includes an invalid FDRA information field value, the corresponding scenario may include one of downlink control information carrying cell dormancy indication information, cell non-scheduling, type 3 hybrid automatic repeat request acknowledgement. The terminal may distinguish the scenario according to the value of the FDRA information domain of the reference cell, where in case the value of the FDRA information domain of the reference cell is invalid, the terminal may determine one of type 3 hybrid automatic repeat request acknowledgement and downlink control information carrying secondary cell dormancy indication information. It should be noted that, the rule for distinguishing the scene is predefined (for example, a protocol convention or a network configuration), and the terminal determines that the hybrid automatic repeat request acknowledgement and the downlink control information of the type 3 carry one of the sleep indication information of the secondary cell, but does not distinguish the scene according to the value of the FDRA information field of the other cell when the value of the FDRA information field of the reference cell is invalid.

the number of cells corresponding to the invalid FDRA information threshold value and the number threshold value meet a first relation, and the downlink control information is determined to carry the auxiliary cell dormancy indication information, or one of the type 3 hybrid automatic repeat request acknowledgement and the downlink control information is determined to carry the auxiliary cell dormancy indication information;

and the number of the cells corresponding to the invalid FDRA information field and the number threshold value do not meet a first relation, and the cells are determined not to be scheduled.

For example, in the case that the downlink control information includes an invalid FDRA information field value, and the single-shot hybrid automatic repeat request acknowledgement indicator field in the downlink control information does not exist or has a value of 0, the corresponding scenario may include that the downlink control information carries one of cell dormancy indicator information and cell non-scheduling. The terminal can distinguish the scenes according to the number of the cells corresponding to the invalid FDRA information threshold, wherein under the condition that the first relation is not satisfied between the number of the cells corresponding to the invalid FDRA information threshold and the number threshold, the scene can be distinguished, and the specific scene is that the cells are not scheduled; under the condition that the number of cells corresponding to the invalid FDRA information threshold value and the number threshold value meet a first relation, the terminal can distinguish a scene, particularly that downlink control information carries cell dormancy indication information.

It should be noted that the number threshold and/or the first relationship may be determined based on a protocol convention, or may be configured by a network device, where the number threshold may be a value greater than or equal to 1, for example, may be 2, and the first relationship may be, for example, a number greater than the number threshold, or a number less than the number threshold, which is not limited herein.

For example, where the downlink control information includes an invalid FDRA information field value, the corresponding scenario may include one of downlink control information carrying cell dormancy indication information, cell non-scheduling, type 3 hybrid automatic repeat request acknowledgement. The terminal can distinguish the scenes according to the number of the cells corresponding to the invalid FDRA information threshold, wherein under the condition that the first relation is not satisfied between the number of the cells corresponding to the invalid FDRA information threshold and the number threshold, the scene can be distinguished, and the specific scene is that the cells are not scheduled; under the condition that the number of cells corresponding to the invalid FDRA information threshold value and the number threshold value meet a first relation, the terminal can distinguish the scene as one of the hybrid automatic repeat request acknowledgement of the type 3 and the downlink control information carrying the auxiliary cell dormancy indication information.

the information for determining that the downlink control information actually schedules the cell includes an FDRA information field, and it is determined that the cell is not scheduled.

In some embodiments, the manner of determining the actual scheduling cell of the downlink control information may include two manners, where one manner is to determine the actual scheduling cell of the downlink control information according to the FDRA information domain; another is to determine the actual scheduling cell of the downlink control information from the RRC signaling received scheduling cell group List (scheduling cell combo-List) and the information field in the MC DCI, for example, for DCI 0_3, the scheduling cell group List may be for scheduling cell combo-List DCI-0-3, for DCI 1_3, the scheduling cell group List may be for scheduling cell combo-List DCI-1-3, and then determine the cell group in this List as the actual scheduling cell based on the information field scheduling cell indication (scheduled cell indicator) in the downlink control information.

The terminal may determine that the information for determining the downlink control information actual scheduling cell does not include the FDRA information field in case that the RRC signaling configures the scheduling cell group list, and may determine that the information for determining the downlink control information actual scheduling cell includes the FDRA information field in case that the RRC signaling does not configure the scheduling cell group list.

For example, in the case that the downlink control information includes an invalid FDRA information field value, and the single-shot hybrid automatic repeat request acknowledgement indicator field in the downlink control information does not exist or has a value of 0, the corresponding scenario may include that the downlink control information carries one of cell dormancy indicator information and cell non-scheduling. Under the condition that the information for determining the actual scheduling cell of the downlink control information comprises an FDRA information domain, the terminal can distinguish a scene, particularly that the cell is not scheduled; under the condition that the information used for determining that the downlink control information actually schedules the cell does not comprise the FDRA information domain, the terminal can distinguish the scene, specifically that the downlink control information carries the cell dormancy indication information.

For example, where the downlink control information includes an invalid FDRA information field value, the corresponding scenario may include one of downlink control information carrying cell dormancy indication information, cell non-scheduling, type 3 hybrid automatic repeat request acknowledgement. Under the condition that the information for determining the actual scheduling cell of the downlink control information comprises an FDRA information domain, the terminal can distinguish a scene, particularly that the cell is not scheduled; the terminal can distinguish between a hybrid automatic repeat request acknowledgement of type 3 and a downlink control information carrying one of the secondary cell dormancy indication information when the information used for determining the actual scheduling cell of the downlink control information does not include the FDRA information field.

The first information indication is used for the terminal determination scenario is exemplarily described below by several embodiments.

In some embodiments, the first information indicates a scene for terminal determination, including at least one of:

the value of at least one information field is a first value and is used for indicating that a terminal scene is that a cell is not scheduled;

the value of at least one information field is a second value, which is used for indicating that the terminal scene carries the auxiliary cell dormancy indication information for the downlink control information, or is one of the hybrid automatic repeat request acknowledgement of the type 3 and the auxiliary cell dormancy indication information for the downlink control information.

the newly defined information field indicates a second value, and is used for determining that the downlink control information carries the auxiliary cell dormancy indication information or is one of type 3 hybrid automatic repeat request acknowledgement and the downlink control information carries the auxiliary cell dormancy indication information.

The type of at least one other information field is a first type, and is used for indicating a terminal to determine that a cell is not scheduled;

the type of at least one other information field is a second type, and is used for determining that the downlink control information carries the auxiliary cell dormancy indication information, or is one of the hybrid automatic repeat request acknowledgement and the downlink control information carrying the auxiliary cell dormancy indication information of the type 3.

It should be noted that the at least one other information field may include one information field or include a plurality of information fields. For example, the at least one other information field includes an information field that is not limited to the Antenna port information field, HARQ process number information field, and the like. The first type and the second type include, but are not limited to, type-1A, type-1B, type-1C, type-2, type-3. Wherein, for the type-1B information field, the downlink control information may include one type information field, which may be used for indicating an index of an information combination of at least one scheduled cell; for a type-3 information field, the downlink control information may include one or more of the type information fields, which may be determined as one of type-1A, type-1B, type-2 by way of a predefined or network device configuration.

The value of the FDRA information field corresponding to the reference cell in the downlink control information is invalid, and the value is used for determining that the downlink control information carries the auxiliary cell dormancy indication information or is one of the type 3 hybrid automatic repeat request acknowledgement and the downlink control information carries the auxiliary cell dormancy indication information.

the number of the cells corresponding to the invalid FDRA information threshold value and the number threshold value meet a first relation, and the method is used for determining that the downlink control information carries the auxiliary cell dormancy indication information or one of the type 3 hybrid automatic repeat request acknowledgement and the downlink control information carries the auxiliary cell dormancy indication information;

the number of cells corresponding to the invalid FDRA information field and the number threshold do not meet a first relation, and the first relation is used for indicating the terminal to determine that the cells are not scheduled.

the information used for determining the downlink control information actually scheduled cell does not comprise an FDRA information domain, and is used for determining that the downlink control information carries auxiliary cell dormancy indication information or one of type 3 hybrid automatic repeat request acknowledgement and the downlink control information carries auxiliary cell dormancy indication information;

the information for determining the actual scheduling cell of the downlink control information includes an FDRA information field for instructing the terminal to determine that the cell is not scheduled.

In some embodiments, the manner of determining the actual scheduling cell of the downlink control information may include two manners, where one manner is to determine the actual scheduling cell of the downlink control information according to the FDRA information domain; another is to first receive a scheduling cell group List (scheduling cell combo-List) through RRC signaling, for example, for DCI 0_3, it may be ScheduledCellCombo-listdi-0-3, for DCI 1_3, it may be ScheduledCellCombo-listdi-1-3, and then determine that the cells are combined into an actually scheduled cell in the List based on an information field scheduling cell indication (field scheduled cell indicator) in the downlink control information.

In some embodiments, the terminal may be a Rel-18 and subsequent release terminal, and the terminal may receive DCI for multi-cell scheduling, receive PDSCH of multiple cells or transmit PUSCH of multiple cells based on indication information corresponding to the DCI;

in some embodiments, DCI scheduling a plurality of cell data may be referred to as MC DCI. Illustratively, DCI scheduling a plurality of cell PUSCHs is referred to as DCI 0_3, and DCI scheduling a plurality of cell PDSCH is referred to as DCI 1_3.

The FDRA domain of the MC DCI belongs to a type 2 domain, i.e., for different cells, the scheduling status of the different cells is indicated with different FDRA domains. Wherein, the MC DCI indicates the scheduling state of the cell based on different FDRA domains under the condition that the schedulcellcombo-List DCI 0_3 is not configured or the schedulcellcombo-List DCI 1_3 is not configured. The method specifically comprises the following steps: if the FDRA threshold corresponding to the cell 1 is invalid, the terminal determines that the cell 1 is not scheduled and corresponds to the scenario 3 (i.e., the cell is not scheduled). The invalid FDRA is described in the previous examples.

Considering that under the condition that the FDRA value corresponding to the cell 1 is invalid and the one shot HARQ-ACK indicator domain corresponding to the MC DCI does not exist or the indicated value is 0, the terminal recharvests the existing field to obtain corresponding Scell domain information, and corresponds to the scene 2 (namely, the downlink control information carries the auxiliary cell dormancy indication information).

The core of scenario 2 and scenario 3 is whether the terminal needs to further read the field of repurpose to obtain corresponding Scell dormancy information, where repurpose field includes one or more of the following fields:

Modulation and coding scheme of transport block 1

New data indicator of transport block 1

Redundancy version of transport block 1

HARQ process number

Antenna port(s)

DMRS sequence initialization

for scenario 2 and scenario 3, the terminal distinguishes between scenario 2 and scenario 3 as follows.

Example 1: additional information fields or information bits (e.g., newly defined information fields or newly defined bits) are introduced to distinguish between the two scenarios.

Example 1-1: the terminal distinguishes between the two scenarios based on antenna port field of cell 1. Exemplarily, if antenna port field of cell 1 is configured as type 1a, the corresponding cell 1 is scenario 3; if antenna port field of cell 1 is configured as type 2, then the corresponding cell 1 is scenario 2.

Examples 1-2: the field may be one or more of the above repurpose fields, and if the bit indicated by all fields is 0, the field corresponds to scenario 3; otherwise, corresponding to scenario 2. Or if the bit indicated by all field is 1, corresponding to scene 3; otherwise, corresponding to scenario 2.

Examples 1-3: adding a new information field, wherein the field occupies 1 bit, and the field is indicated as 0 and corresponds to scene 3 in an exemplary manner; otherwise, corresponding to scenario 2. Or, illustratively, the field is indicated as 1, corresponding to scenario 3; otherwise, corresponding to scenario 2.

Examples 1 to 4: the field may be an information field corresponding to type2 in the MC DCI, and corresponding to cell 1, the field including one or more of,

domains corresponding to TB1 and/or TB 2;

Modulation and coding scheme；

New data indicator；

Redundancy version；

HARQ process number,antenna port(type 2)；

for example, if bit 1 in the TB 1MCS, or bit 1 in the TB 2MCS, or NDI field of TB1, or NDI field of TB2 indicates 0, corresponding to scene 3; otherwise, corresponding to scenario 2. Or, illustratively, the field (bit) is indicated as 1, corresponding to scenario 3; otherwise, corresponding to scenario 2.

Examples 1 to 5: the bit may be the first bit in all fields for Scell dorma for cell 1, e.g., the 1 st bit of MCS for cell 1 for TB1, or the last 1 bit in all fields for Scell dorma for cell 1, e.g., DMRS sequence initialization, or the last 1 bit (e.g., if Antenna port(s) is configured as type2, note: may also be decoupled from the e.g., scene) of Antenna port(s) for cell 1, or the last 1 bit (e.g., if Antenna port(s) is configured as type1a, note: may also be decoupled from the e.g., scene) of HARQ process number for cell 1). The method can avoid changing the mapping sequence of the Scell field bits and the repurpose field.

Based on embodiment 1, when the number of cells 1 in the scenario 2 is multiple, the terminal determines corresponding Scell dorsum information only based on the indication information of the reference cell, and the reference cell is, for example, a cell with the smallest cell id in the multiple cells 1; or, the reference cell is a cell 1 with the smallest cell id in the cell set and meeting the above condition; or, the reference cell is a Pcell cell;

example 2: and defining a reference cell, wherein the terminal indicates corresponding Scell dorsum information based on a repurpose domain corresponding to the reference cell only under the condition that FDRAin on the reference cell exists and the corresponding one shot HACQ-ACK indicator is not existed or indicated as 0. The repurpose domain is given in example 1 and is not described here.

Example 2-1: the reference cell is the cell with the smallest cell id in the cell set.

Example 2-2: the reference cell is a cell corresponding to the minimum/large cell id in at least one cell corresponding to the invalid FDRA;

examples 2-3: the reference cell is a Pcell cell.

Example 3: and defining a first condition, and analyzing corresponding Scell criterion information based on a reference cell by the terminal as long as one shot HACQ-ACK indicator does not exist or is indicated as 0 and the first condition is met.

The first condition includes:

example 3-1: determining the number N of cells corresponding to the invalid FDRA, wherein N is larger than a first parameter or N is smaller than the first parameter;

the first parameter is determined based on a signaling indication or a predefined manner, the first parameter being illustratively equal to 2;

the reference cell is a cell with the smallest cell id among at least one cell meeting the requirement of an invalid FDRA.

Example 4: only in the indication scene that the terminal does not determine the cell based on FDRA, case 2 is adopted; illustratively, the terminal has no scheduleCellCombo-ListDCI-0-3 configured or scheduleCellCombo-ListDCI-1-3 configured and meets the following on the reference cell: the index FDRA, one shot HACQ-ACK indicator does not exist or is indicated as 0. The terminal determines corresponding Scell functionality information based on a reference cell, where the reference cell is:

example 4-1: the reference cell is one or more of the cells belonging to the scheduling indicated by the MC DCI, the scheduled cell being indicated based on field scheduled cell indicator;

example 4-2: the reference cell is one or more of cell sets corresponding to the MC DCI;

examples 4-3: the reference cell is one or more of unscheduled cells which belong to the MC DCI indication, and the terminal determines whether the cells are scheduled or not based on field scheduled cell indicator;

Examples 4-4: the reference cell is a cell corresponding to the smallest/large cell id among at least one cell satisfying the three conditions described in embodiments 4-1 to 4-3.

It can be seen that the main design rule of this embodiment is that under the condition of determining the invalid FDRA, different indication scenes are provided. The method is beneficial to reducing the processing complexity of the terminal and realizing the understanding consistency of the base station and the terminal.
