[0002] Communication systems in related technologies can support aggregation of up to 16 cells and support scheduling of physical channels in multiple cells using a single downlink control information (DCI).

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0046] The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0047] It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining."

[0048] First, the relevant technologies involved in the embodiments of this application are introduced:

[0049] 1) Multi-Carrier Scheduling:

[0050] The "Multi-Carrier" project supports the ability for a single DCI (e.g., DCI format 0_3 or DCI format 1_3) to schedule multiple physical downlink shared channels (PDSCH) / physical uplink shared channels (PUSCH). These scheduled PDSCHs / PUSCHs can be transmitted in different cells.

[0051] The information fields included in the DCI that supports simultaneous scheduling of multiple physical channels can be roughly divided into three categories:

[0052] 1. Type-1 field: used to indicate common information. DCI contains only one Type-1 field, and all cells scheduled by the DCI use the common information indicated by the Type-1 field.

[0053] 2. Type-2 field: used to indicate the specific information of each scheduled cell. The DCI may contain one or more Type-2 fields, each of which corresponds to a scheduled cell.

[0054] 3. Type-3 field: This field can be configured as either Type-1 or Type-2. The Type-3 field can also be used to indicate precoding information, the number of layers, and antenna ports.

[0055] 2) Physical Downlink Control Channel (PDCCH) coding rules:

[0056] In related technologies, DCI carried by PDCCH is transmitted using polarization coding.

[0057] The cyclic redundancy check (CRC) encoder used in Polar coding is a linear encoder and generates a systematic code. Therefore, the CRC encoder can be regarded as a generator matrix, and the information bits (bits) can be multiplied by the generator matrix to obtain the CRC bits. After the CRC bits are generated, the bit stream obtained by concatenating the information bits and the CRC bits is interleaved, so that a portion of the CRC bits originally located at the end of the bit stream are replaced before the information bits, and the information bits are located before the CRC bits with which they have a check relationship. In this way, during decoding, the decoded part of the information bits can be CRC-checked. If the check fails, the decoding is stopped, thereby realizing the early stop function of the decoding. Therefore, it is necessary to cascade an interleaver after the CRC encoder.

[0058] The maximum interleaving length of the interleaving matrix supported in the related art is 164 bits. That is, in the related art, the total number of DCI bits and CRC bits carried by the PDCCH must not exceed 164 bits. Generally, the CRC bit length is fixed at 24 bits, so the DCI information bits must not exceed 140 bits. However, it should be noted that the limit on the number of information bits may vary in different communication systems and is not limited to the upper limit of 140 DCI information bits.

[0059] In the related art, although a maximum of 16 cells can be supported for aggregation, one DCI can only schedule physical channels in a maximum of 4 cells at the same time.

[0060] Obviously, if one DCI is used to schedule more cells simultaneously, the following advantages cannot be ignored:

[0061] Reduced user equipment (UE) power consumption: When a DCI schedules more cells, the UE needs to monitor fewer DCIs, and accordingly, the total number of blind detections can be reduced.

[0062] Reduced signaling overhead and improved transmission efficiency: When a DCI schedules more cells, more scheduled cells share the Type 1 field and CRC bits in the DCI, reducing the total amount of information required to schedule multiple cells and the transmission resources required to schedule multiple cells.

[0063] However, using a single DCI to schedule more cells inevitably requires supporting more Type 2 fields in the DCI, which would cause the total number of DCI information bits to exceed 140, violating the aforementioned coding rules. Therefore, the capacity limitation of polar codes is a significant factor restricting the number of cells that can be simultaneously scheduled by a single DCI.

[0064] Based on the above problems, the present application provides a scheduling method that supports simultaneous scheduling of more cells under the condition of coding capacity limitation, thereby effectively reducing UE power consumption, reducing signaling overhead, and improving the utilization efficiency of transmission resources.

[0077] It should be understood that, in one scheduling, if one physical channel is scheduled on each cell or carrier, then "N cells" can also be understood as "N physical channels".

[0078] FIG2 is a flow chart of a scheduling method provided by some exemplary embodiments of the present application. The method is schematically illustrated by taking the method executed by the terminal device 120 shown in FIG1 as an example. The method includes at least some of the following steps:

[0079] Step 210: Receive a first signaling, where the information indicated by the first signaling includes a first quantity;

[0080] The first signaling comes from the network device, and the first number is an integer greater than or equal to 0.

[0081] In some embodiments, the first quantity is the number of second signalings that the network device expects the terminal device to receive; or it is understood that the first quantity is the number of second signalings that the network device instructs the terminal device to receive; or it is understood that the first quantity is the number of second signalings that the terminal device needs to receive; or it is understood that the first quantity is the number of second signalings sent by the network device to the terminal device; or it is understood that the first quantity is the number of second signalings associated with the first signaling.

[0082] The second signaling associated with the first signaling can be understood as the second signaling used in conjunction with the first signaling; or understood as the second signaling that schedules a second number of physical channels or cells together with the first signaling.

[0083] Among them, the physical channels include at least one of PDSCH, PUSCH, physical uplink control channel (Physical Uplink Control Channel, PUCCH), physical sidelink shared channel (Physical Sidelink Share Channel, PSSCH), physical sidelink control channel (Physical Sidelink Control Channel, PSCCH), etc.

[0084] In some embodiments, the first number is explicitly indicated by the first signaling, or the first number is implicitly indicated by the first signaling.

[0085] In some embodiments, the specific manner of implicit indication may be agreed upon by a communication protocol, configured by a network device, or determined by negotiation between the network device and the terminal device.

[0086] In some embodiments, the first signaling is also called basic signaling, main signaling, first-level signaling, level 0 signaling, etc.

[0087] Step 230: Receive a first quantity of second signaling.

[0088] The second signaling comes from a network device.

[0089] In some embodiments, the second signaling may be called extended signaling, slave signaling, auxiliary signaling, i-th level signaling, etc.

[0090] In some embodiments, the first signaling and the second signaling can be understood as control signaling, scheduling signaling, or authorization signaling. Exemplarily, in an uplink or downlink transmission scenario, the first signaling and / or the second signaling is DCI; in a sidelink transmission scenario, the first signaling and / or the second signaling is sidelink control information (SCI).

[0091] The first signaling and the second signaling are used to schedule a second number of physical channels or cells, where the second number is a positive integer, that is, the number of scheduled physical channels or scheduled cells is the second number.

[0092] In some embodiments, when the first number is equal to 0, it indicates that the number of second signalings is 0, and the terminal device receives 0 second signalings. Alternatively, when the first number is equal to 0, the terminal device does not receive the second signaling. Alternatively, when the first number is equal to 0, the terminal device does not perform blind detection on the second signaling.

[0093] In some embodiments, the terminal device receives the first signaling and the second signaling. The terminal device can confirm whether the number of received second signalings meets the first number based on the first number indicated by the first signaling, that is, whether the received second signalings are complete, thereby improving reliability.

[0094] Exemplarily, the terminal device determines based on the first quantity that the number of received second signalings is less than the first quantity, indicating that the second signaling is lost. The terminal device sends feedback information to the network device, and the network device retransmits the lost second signaling based on the feedback information.

[0095] In some embodiments, the terminal device receives the first signaling first and then the second signaling. The terminal device may confirm whether the number of received second signalings meets the first number based on the first number indicated by the first signaling. When the number of received second signalings equals the first number, the terminal device stops blind checking the second signaling, thereby reducing the number of meaningless blind checks and thus reducing power consumption of the terminal device.

[0096] In some embodiments, the information indicated by the first signaling and the second signaling overlap; or, the information indicated by the first signaling and the second signaling are different.

[0097] In some embodiments, the formats of the first signaling and the second signaling are different, that is, the information fields of the first signaling and the second signaling are different. The difference between the information fields of the first signaling and the second signaling can be understood as a difference in quantity or function between at least one information field of the first signaling and at least one information field of the second signaling.

[0098] In some embodiments, the scheduling information of a physical channel among the second number of physical channels is carried by a first signaling, or carried by a second signaling, or carried by a first signaling and a second signaling, or carried by multiple second signalings, or carried by a first signaling and multiple second signalings.

[0099] In some embodiments, the scheduling information of a cell among the second number of cells is carried by a first signaling, or carried by a second signaling, or carried by a first signaling and a second signaling, or carried by multiple second signalings, or carried by a first signaling and multiple second signalings.

[0100] In some embodiments, scheduling information of some physical channels in the second number of physical channels is carried by the first signaling, or carried by the second signaling, or carried by the first signaling and the second signaling.

[0101] In some embodiments, scheduling information of all physical channels in the second number of physical channels is carried by the first signaling, or carried by the second signaling, or carried by the first signaling and the second signaling.

[0102] In some embodiments, scheduling information of some cells in the second number of cells is carried by the first signaling, or carried by the second signaling, or carried by the first signaling and the second signaling.

[0103] In some embodiments, the scheduling information of all cells in the second number of cells is carried by the first signaling, or carried by the second signaling, or carried by the first signaling and the second signaling.

[0104] It should be understood that in the embodiments of the present application, transmission can be understood as sending, receiving, or both sending and receiving.

[0105] In summary, the method provided by the embodiment of the present application, since the scheduling of physical channels or cells is jointly implemented by the first signaling and the second signaling, the total number of bits of the first signaling and the second signaling can exceed the coding capacity limit of a single signaling in the related art, thereby realizing the simultaneous scheduling of more physical channels or cells and improving the scheduling efficiency. Moreover, since the first number has been indicated in the first signaling, when the terminal device receives the second signaling, it can not only confirm whether the received second signaling has reached the first number, thereby improving reliability, but also stop blind detection after receiving the first number of second signalings, thereby avoiding power consumption waste caused by meaningless blind detection. In addition, when the first signaling and the second signaling are used to schedule the second number of physical channels or cells, if there is public information corresponding to the scheduled physical channels or scheduled cells in the first signaling and the second signaling, then the larger the value of the second number, the higher the utilization efficiency of the transmission resources corresponding to the first signaling and the second signaling.

[0106] Next, based on the embodiment shown in FIG2 , five aspects are introduced, namely, the first quantity, the first signaling, the second signaling, the physical resource relationship between the first signaling and the second signaling, and the association relationship between the first signaling and the second signaling.

[0107] 1. The first amount of relevant content

[0109] 1. The value of the first quantity

[0110] In some embodiments, the value of the first quantity is related to the value of the second quantity. In the embodiments of the present application, the following two types of correlations are mainly discussed, but this does not mean that the correlation between the value of the first quantity and the value of the second quantity is limited:

[0111] First-class correlation: the value of the first quantity is positively correlated with the value of the second quantity;

[0112] That is, the larger the value of the second number is, the larger the value of the first number is.

[0113] In some embodiments, the value of the first quantity is positively correlated with the value of the second quantity in a linear trend, for example, the value of the first quantity is positively correlated with the value of the second quantity in a positive proportion. Alternatively, the value of the first quantity is positively correlated with the value of the second quantity in a nonlinear trend.

[0114] The second type of correlation: the value of the first quantity is related to the numerical range of the second quantity;

[0115] That is, the value of the first quantity is determined based on the associated numerical range of the second quantity.

[0116] In some embodiments, when the second number belongs to a first numerical range, the value of the first number is a first value, wherein the first value is an integer greater than or equal to 0, and the first numerical range corresponds to a maximum value and a minimum value.

[0117] In some embodiments, the first numerical interval can be understood as a set consisting of a maximum value, a minimum value, and numerical values ​​that are greater than the minimum value and less than the maximum value.

[0118] In some embodiments, the maximum value of the first numerical interval is configured by the network device, or agreed upon by a communication protocol, or determined by the network device and the terminal device.

[0119] In some embodiments, the network device and the terminal device negotiate to determine the maximum value of the first numerical interval. Exemplarily, the network device sends a first negotiation message to the terminal device, the first negotiation message is used to indicate that the maximum value of the first numerical interval is numerical value A; the terminal device sends a second negotiation message to the network device, the second negotiation message is used to indicate that the terminal device accepts the maximum value of the first numerical interval as numerical value A; the network device and the terminal device determine that the maximum value of the first numerical interval is numerical value A. Exemplarily, the network device sends a first negotiation message to the terminal device, the first negotiation message is used to indicate that the maximum value of the first numerical interval is numerical value A; the terminal device sends a second negotiation message to the network device, the second negotiation message is used to indicate that the terminal device refuses to accept the maximum value of the first numerical interval as numerical value A, and recommends that the maximum value of the first numerical interval be numerical value B; the network device sends a third negotiation message to the terminal device, the third negotiation message is used to indicate that the network device accepts the maximum value of the first numerical interval as numerical value B; the network device and the terminal device determine that the maximum value of the first numerical interval is numerical value B.

[0120] In some embodiments, the minimum value of the first numerical interval is configured by the network device, or agreed upon by the communication protocol, or determined by the network device and the terminal device.

[0121] In some embodiments, the network device and the terminal device negotiate to determine the minimum value of the first numerical interval. Exemplarily, the network device sends a first negotiation message to the terminal device, the first negotiation message is used to indicate that the minimum value of the first numerical interval is numerical value C; the terminal device sends a second negotiation message to the network device, the second negotiation message is used to indicate that the terminal device confirms that the minimum value of the first numerical interval is numerical value C; the network device and the terminal device determine that the minimum value of the first numerical interval is numerical value A. Exemplarily, the network device sends a first negotiation message to the terminal device, the first negotiation message is used to indicate that the minimum value of the first numerical interval is numerical value C; the terminal device sends a second negotiation message to the network device, the second negotiation message is used to indicate that the terminal device denies confirming that the minimum value of the first numerical interval is numerical value C, and suggests that the minimum value of the first numerical interval is numerical value D; the network device sends a third negotiation message to the terminal device, the third negotiation message is used to indicate that the network device confirms that the minimum value of the first numerical interval is numerical value D; the network device and the terminal device determine that the minimum value of the first numerical interval is numerical value D.

[0122] In some embodiments, the number of candidate numerical intervals for the second number is at least two. If the second number belongs to the i-th interval in the candidate numerical interval, the value of the first number is the second value; if the second number belongs to the i+1-th interval in the candidate numerical interval, the value of the first number is the third value.

[0123] The maximum value of the i-th interval is less than the minimum value of the (i+1)-th interval, the second value is less than the third value, the second value is an integer greater than 0, and the third value is an integer greater than 0.

[0124] In some embodiments, the candidate numerical intervals (including the number of candidate numerical intervals and / or the maximum value corresponding to the candidate numerical intervals and / or the minimum value corresponding to the candidate numerical intervals) are configured by the network device, or agreed upon by the communication protocol, or determined by the network device and the terminal device.

[0125] In some embodiments, the numerical range to which the second number belongs is configured by the network device, or agreed upon by a communication protocol, or determined by the network device and the terminal device.

[0126] In some embodiments, the value of the first quantity is configured by the network device, or agreed upon by a communication protocol, or determined by the network device and the terminal device.

[0127] It should be understood that in the embodiments of the present application, the first numerical interval, the second numerical interval, and the third numerical interval are used as examples to illustrate the correlation between the values ​​of the first quantity and the numerical intervals to which the second quantity belongs, but this does not mean that the numerical intervals to which the second quantity belongs or the candidate numerical intervals are limited. The second number of candidate numerical intervals can be fewer, such as only the first numerical interval or only the first numerical interval and the second numerical interval; the second number of candidate numerical intervals can also be more, such as in addition to the above three numerical intervals, there are also a fourth numerical interval, a fifth numerical interval, and so on.

[0128] It should be understood that the first value, the second value, and the third value may increase arithmetic progression, or increase in equal proportion, or increase according to other mathematical rules, or increase randomly.

[0129] For example, when the second number is in the interval (0, X], the value of the first number is 0; when the second number is in the interval (X, Y], the value of the first number is 1; when the second number is in the interval (Y, Z], the value of the first number is 2; and so on. <Y<Z。

[0130] For example, when the second number is in the interval (0, X], the value of the first number is 1; when the second number is in the interval (X, Y], the value of the first number is 2; when the second number is in the interval (Y, Z], the value of the first number is 4; and so on. <Y<Z。

[0131] In some embodiments, the value of the second number is smaller, indicating that the number of scheduled physical channels or scheduled cells is smaller, and thus, the number of information bits required for scheduling is also smaller. The first signaling may carry the complete scheduling information required for the second number of physical channels or cells, that is, the first signaling has the ability to independently schedule the second number of physical channels or cells. In this case, the value of the first number may be 0, meaning that the number of second signaling bits received by the terminal device is 0.

[0132] In some embodiments, the first signaling does not have the ability to schedule physical channels or cells separately, or does not support the first signaling to carry the complete scheduling information required for the second number of physical channels or cells, or the first signaling cannot carry the complete scheduling information required for the second number of physical channels or cells (which may be due to the lack of separate scheduling capabilities or due to coding capacity limitations). In other words, the scheduling of the second number of physical channels or cells must be jointly implemented by the first signaling and the second signaling, or the complete scheduling information required for the second number of physical channels or cells is composed of the first signaling (part or all of the information included therein) and the second signaling (part or all of the information included therein), then the value of the first number must be greater than 0, and the number of second signalings received by the terminal device is at least one.

[0133] 2. Maximum value of the first quantity

[0134] In some embodiments, there is an upper limit to the value of the first number, that is, there is a maximum value of the first number.

[0135] In some embodiments, the maximum value of the first quantity is determined based on first configuration information. The first configuration information is sent by the network device. Therefore, the network device can flexibly configure the first quantity or the maximum value of the first quantity based on at least one of actual scheduling conditions, the network device's own scheduling capabilities, terminal device capabilities, cell aggregation level, the number of aggregated cells, transmission resources, etc., to improve scheduling efficiency and system transmission efficiency.

[0240] 3. Related Contents of the Second Signaling

[0241] 1. Number of bits of the second signaling

[0242] In some embodiments, the number of bits in the second signaling is determined based on the maximum value of the second number. Alternatively, the number of bits in the second signaling is related to the value of the second number, for example, the number of bits in the second signaling is positively correlated with the value of the second number, and the larger the value of the second number, the larger the number of bits in the second signaling. Alternatively, the sum of the number of bits in the first signaling and the second signaling is related to the value of the second number, for example, the sum of the number of bits in the first signaling and the second signaling is positively correlated with the value of the second number.

[0243] In some embodiments, the number of bits in the second signaling is related to the number of bits in the first signaling. Exemplarily, when the second number is the same, the number of bits in the second signaling when the first signaling does not include the third information is greater than the number of bits in the second signaling when the first signaling includes the third information. Exemplarily, when the second number is the same, the greater the number of bits of the third information included in the first signaling, the smaller the number of bits in the second signaling.

[0244] In some embodiments, there is an upper limit on the number of bits in the second signaling, that is, there is a maximum value for the number of bits in the second signaling.

[0245] In some embodiments, the maximum value of the number of bits in the second signaling is agreed upon by the communication protocol. Alternatively, the maximum value of the number of bits in the second signaling is configured by the network device, for example, based on at least one of the actual scheduling situation, the scheduling capability of the network device itself, the capability of the terminal device, the cell aggregation level, the number of aggregated cells, transmission resources, etc. Alternatively, the maximum value of the number of bits in the second signaling is a default value. Alternatively, the maximum value of the number of bits in the second signaling is determined by negotiation between the network device and the terminal device.

[0246] 2. Information included in the second signaling

[0247] In some embodiments, the second signaling includes at least one of the following information:

[0248] Identification information of the second signaling;

[0249] The identification information includes at least one of an identifier, an index, a number, a value, and the like.

[0250] In some embodiments, the identification information of the second signaling may be used to identify the number or index of the current second signaling in the first number of second signalings.

[0251] In some embodiments, each second signaling has one-to-one corresponding identification information, and the second signaling includes its own corresponding identification information.

[0252] In some embodiments, the second signaling includes identification information of a first number of second signalings (ie, identification information of all second signalings).

[0253] In some embodiments, the second signaling includes identification information of the current second signaling (i.e., its own identification information) and / or identification information of other second signalings, wherein the other second signalings refer to at least one other second signaling in the first number of second signalings except the current second signaling.

[0254] If the second signaling includes identification information of the second signaling, the terminal device can obtain information based on the information about which information fields the current second signaling includes, such as whether it includes physical resource information of other second signaling, quantity information of other second signaling, format information of other second signaling, etc., thereby improving scheduling reliability and system efficiency.

[0255] If the second signaling includes identification information of the second signaling, the terminal device can determine the association relationship between the current second signaling and other second signalings based on the information. Exemplarily, at least one of the physical resource information of the current second signaling, the quantity information of other second signalings, and the format information of other second signalings is indicated by other second signalings. Exemplarily, the current second signaling indicates at least one of the physical resource information of other second signalings, the quantity information of other second signalings, and the format information of other second signalings, thereby improving scheduling reliability and system efficiency.

[0256] If the second signaling includes identification information of the second signaling, the terminal device can learn, based on this information, which physical channels, or which physical channel, or which cells, or which cell the current second signaling is used to schedule. In other words, the terminal device can learn, based on this information: the correspondence between the current second signaling and some or all of the second number of physical channels; or the correspondence between the current second signaling and some or all of the second number of cells, thereby improving scheduling reliability and system efficiency.

[0257] If the second signaling includes identification information of the second signaling, the terminal device can determine the number of second signalings received based on the information. Furthermore, by comparing with the first number indicated by the first signaling, the terminal device can determine whether the first number of second signalings has been received. If the first number of second signalings has been received (that is, all second signalings have been received), the blind detection of the second signaling is stopped, thereby reducing power consumption and improving scheduling efficiency. Alternatively, by comparing with the first number indicated by the first signaling, the terminal device can determine whether the second signaling is lost or reception fails, thereby improving system reliability.

[0258] Identification information of the first signaling;

[0259] If the second signaling includes identification information of the first signaling, the terminal device can determine the first signaling associated with the current second signaling based on the information, that is, determine which first signaling is used in conjunction with the current second signaling.

[0260] identification information of at least one physical channel of the second number of physical channels;

[0261] That is, identification information of at least one physical channel scheduled by the current second signaling. That is, identification information of the scheduled physical channel corresponding to the current second signaling.

[0262] If the second signaling includes identification information of at least one physical channel among the second number of physical channels, the terminal device can determine based on the information that the current second signaling is used to schedule at least one physical channel corresponding to the identification information, or that the current second signaling can schedule at least one physical channel corresponding to the identification information.

[0263] identification information of at least one cell among the second number of cells;

[0264] That is, the identification information of at least one cell scheduled by the current second signaling. That is, the identification information of the scheduled cell corresponding to the current second signaling.

[0265] If the second signaling includes identification information of at least one cell among the second number of cells, the terminal device can determine based on the information that the current second signaling is used to schedule one or more cells corresponding to the identification information, or that the current second signaling can schedule one or more cells corresponding to the identification information.

[0266] First information, the first information including signaling parameters of at least one second signaling, the at least one second signaling being at least one of the first number of second signalings;

[0267] For the relevant content of the first information, please refer to the above content and will not be repeated here.

[0268] If the second signaling includes the first information, it indicates that the current second signaling can be used to indicate signaling parameters of other second signalings, where the other second signalings refer to at least one other second signaling in the first number of second signalings, except for the current second signaling. Therefore, the terminal device can receive other second signalings based on the first information included in the second signaling, thereby reducing the number of blind detections of the terminal device, reducing power consumption, and improving scheduling reliability and transmission efficiency.

[0269] Third information, the third information includes scheduling information (such as transmission parameters) of at least one physical channel among the second number of physical channels, or scheduling information (such as transmission parameters) of at least one cell among the second number of cells.

[0270] For the relevant content of the third information, please refer to the above content and will not be repeated here.

[0271] In some embodiments, the network device configures the third information in the second signaling based on at least one of the actual scheduling situation, the scheduling capability of the network device itself, the capability of the terminal device, the cell aggregation level, the number of aggregated cells, the transmission resources, the value of the first quantity, the value of the second quantity, and the quality of service class identifier (QCI) to improve scheduling reliability and system efficiency.

[0272] In some embodiments, the network device uniformly configures the scheduling information of the scheduled physical channel or the scheduled cell corresponding to the second signaling through the third information in the second signaling, thereby improving system efficiency.

[0273] In some embodiments, the network device independently configures the scheduling information of each scheduled physical channel or scheduled cell corresponding to the second signaling through the third information in the second signaling, thereby improving scheduling flexibility, reliability and system efficiency.

[0274] In some embodiments, the complete scheduling information for a scheduled physical channel or cell is carried by multiple second signalings, or by one first signaling and multiple second signalings. These multiple second signalings can then carry different parts of the complete scheduling information. In other words, the information contained in multiple second signalings used to schedule the same physical channel or cell can be different. The information contained in each second signaling can be configured or set separately, making the scheduling information included in each second signaling more refined, flexible, and richer, thereby improving scheduling flexibility.

[0275] In some embodiments, the second signaling is DCI.

[0276] In some embodiments, the transmission of the second signaling is performed based on at least one of a PDCCH coding method, a PDCCH modulation method, a PDCCH resource mapping method, and a PDCCH physical channel structure.

[0277] In some embodiments, the transmission of the second signaling is performed based on at least one of a physical channel structure of the PDSCH and a reference signal structure of the PDSCH.

[0278] In some embodiments, the second signaling is transmitted based on polarization coding, or Low Density Parity Check Code (LDPC) coding, or Reed-Muller (RM) coding.

[0279] Exemplarily, the channel coding scheme adopted by the channel carrying the second signaling is a polarization coding scheme, and reference may be made to the relevant content in Section 5.3.1 of 3GPP TS 38.212 V15.11.0 (2021-06). Or the channel coding scheme adopted by the channel carrying the second signaling is an LDPC coding scheme, and reference may be made to the relevant content in Section 5.3.2 of 3GPP TS 38.212 V15.11.0 (2021-06). Or the channel coding scheme adopted by the channel carrying the second signaling is an RM coding scheme, and reference may be made to the relevant content in Section 5.3.3 of 3GPP TS 38.212 V15.11.0 (2021-06).

[0280] In some embodiments, the payloads of different second signaling messages are the same or different. For example, the number of payloads of different second signaling messages is different, or the number of payloads of different second signaling messages is the same. For example, the content of the payloads of different second signaling messages is completely different, or the content of the payloads of different second signaling messages is partially the same.

[0281] In some embodiments, the payload of the second signaling and / or the maximum value of the payload of the second signaling is determined based on at least one of the following:

[0282] Second configuration information, where the second configuration information is used to configure a payload of the second signaling and / or a maximum value of the payload of the second signaling;

[0283] The number of physical resource blocks (PRBs) of at least one cell in the aggregated cell corresponding to the second number of physical channels or cells;

[0284] The number of CBGs in at least one cell in the aggregated cell;

[0285] The number of codewords of at least one cell in the aggregated cells;

[0286] • Precoding information of at least one cell in the aggregated cells.

[0287] The second configuration information is sent by the network device. If the second configuration information is used to configure the payload of the second signaling, the payload of the second signaling is determined based on the second configuration information. If the second configuration information is used to configure the maximum value of the payload of the second signaling, the payload of the second signaling and / or the maximum value of the payload of the second signaling are determined based on the second configuration information.

[0288] The aggregated cell refers to a cell aggregated with the second number of physical channels or cells, that is, the aggregated cell is an aggregated cell associated with the second number of physical channels or cells.

[0289] In some embodiments, the payload of the second signaling and / or the maximum value of the payload of the second signaling is determined based on at least one of the following:

[0290] The number of PRBs of the scheduled physical channel corresponding to the second signaling;

[0291] The number of CBGs of the scheduled physical channel corresponding to the second signaling;

[0292] The number of codewords of the scheduled physical channel corresponding to the second signaling;

[0293] Precoding information of the scheduled physical channel corresponding to the second signaling;

[0294] The number of PRBs of the scheduled cell corresponding to the second signaling;

[0295] The number of CBGs of the scheduled cell corresponding to the second signaling;

[0296] The number of codewords of the scheduled cell corresponding to the second signaling;

[0297] Precoding information of the scheduled cell corresponding to the second signaling.

[0298] The scheduled physical channel corresponding to the second signaling is, that is, the physical channel corresponding to the identification information of at least one physical channel in the second number of physical channels included in the second signaling. The scheduled cell corresponding to the second signaling is, that is, the cell corresponding to the identification information of at least one cell in the second number of cells included in the second signaling.

[0299] 4. Related content on the physical resource relationship between the first signaling and the second signaling

[0300] 1. Time Domain Relationship between First Signaling and Second Signaling

[0301] In some embodiments, the time domain resources occupied by the second signaling are not earlier than the time domain resources occupied by the first signaling.

[0302] In some embodiments, the time domain relationship between the first signaling and the second signaling satisfies at least one of the following:

[0303] The starting position of the time domain resources occupied by the second signaling is the same as the starting position of the time domain resources occupied by the first signaling;

[0304] The end position of the time domain resources occupied by the second signaling is the same as the end position of the time domain resources occupied by the first signaling;

[0305] The starting position of the time domain resources occupied by the second signaling is the same as the ending position of the time domain resources occupied by the first signaling;

[0306] The starting position of the time domain resources occupied by the second signaling is after the starting position of the time domain resources occupied by the first signaling;

[0307] The end position of the time domain resources occupied by the second signaling is after the end position of the time domain resources occupied by the first signaling;

[0308] The starting position of the time domain resources occupied by the second signaling is after the ending position of the time domain resources occupied by the first signaling.

[0309] In some embodiments, the interval between the time domain resources occupied by the second signaling and the time domain resources occupied by the first signaling is less than a first threshold;

[0310] The first threshold is agreed upon by a communication protocol, configured by a network device, or determined by the terminal device and the network device.

[0311] In some embodiments, the time domain relationship between the first signaling and the second signaling satisfies at least one of the following:

[0312] The interval between the starting time domain unit of the time domain resources occupied by the second signaling and the starting time domain unit of the time domain resources occupied by the first signaling is less than a first threshold;

[0313] The interval between the end time domain unit of the time domain resources occupied by the second signaling and the end time domain unit of the time domain resources occupied by the first signaling is less than a first threshold;

[0314] The interval between the starting time domain unit of the time domain resources occupied by the second signaling and the ending time domain unit of the time domain resources occupied by the first signaling is smaller than a first threshold.

[0315] Exemplarily, the first threshold is t time slots, where t is an integer greater than or equal to 0. As shown in FIG3 , the end position of the time domain resources occupied by the second signaling is the same as the end position of the time domain resources occupied by the first signaling, and the interval between the start time slot of the time domain resources occupied by the second signaling and the start time slot of the time domain resources occupied by the first signaling is less than t time slots.

[0316] Exemplarily, the first threshold is t symbols. As shown in FIG4 , the starting position of the time domain resources occupied by the second signaling is after the starting position of the time domain resources occupied by the first signaling, and the interval between the starting symbol of the time domain resources occupied by the second signaling and the ending symbol of the time domain resources occupied by the first signaling is less than t symbols.

[0317] 2. Transmission resources for the first and second signaling

[0318] In some embodiments, the first signaling and the second signaling are transmitted using agreed physical resources, where the agreed physical resources are configured by the network device, agreed upon by a communication protocol, or determined by negotiation between the network device and the terminal device.

[0319] The physical resources include at least one of time domain resources, frequency domain resources, a search space corresponding to a control channel, an aggregation level corresponding to a control channel, and a candidate set corresponding to a control channel.

[0320] In some embodiments, the physical resources used by the second signaling overlap with the physical resources used by the first signaling. For example, the first signaling and the second signaling are transmitted in the same cell; and / or the first signaling and the second signaling are transmitted in the same bandwidth part (BWP); and / or the first signaling and the second signaling are transmitted in the same time slot; and / or the first signaling and the second signaling are transmitted in the same search space; and so on.

[0321] 5. Correlation between the First Signaling and the Second Signaling

[0322] Considering that the first signaling and the second signaling may include one or more types of information, four association relationships between the first signaling and the second signaling are introduced below by way of example, but this does not mean to limit the association relationship between the first signaling and the second signaling.

[0323] Relationship 1: The first signaling indicates a first quantity and a signaling parameter of the first quantity of the second signaling.

[0324] For example, if the first number is 4, the terminal device may receive the second signaling based on the first number indicated by the first signaling. Based on the first number, the terminal device may determine whether the number of received second signalings reaches the first number to confirm whether the received second signalings are complete and without loss, thereby improving reliability.

[0325] If the first signaling indicates four formats of the second signaling, then the terminal device can receive based on the format indicated by the first signaling, which can improve the reception efficiency, accuracy and reliability.

[0326] Furthermore, if the second signaling is transmitted in the PDCCH, the terminal device may receive the second signaling through blind detection. When the terminal device determines that four second signalings have been received, the blind detection may be stopped, thereby saving power consumption.

[0327] If the first signaling indicates the formats of four second signalings, then the terminal device can perform blind detection based on the formats indicated by the first signaling, which can reduce meaningless blind detection, improve blind detection efficiency, and save power consumption.

[0328] Relationship 2: As shown in FIG5 , the first signaling indicates a first quantity of physical resource information of the second signaling.

[0329] Exemplarily, the first number is 3, and the first signaling uniformly indicates the physical resource information used by the second signaling 1, the second signaling 2, and the second signaling 3, or separately indicates the physical resource information used by the second signaling 1, the second signaling 2, and the second signaling 3. Then, the terminal device can receive the second signaling 1, the second signaling 2, and the second signaling 3 respectively based on the physical resource information indicated by the first signaling, significantly reducing the number of blind detections, and even eliminating the need for blind detection of the second signaling, thereby saving power consumption. Moreover, after receiving the first signaling, the terminal device can independently receive each second signaling, and the interpretation or use of each second signaling does not need to rely on the correct reception of other second signalings, and has higher reliability. However, in this case, the number of bits of the first signaling may be larger.

[0330] Furthermore, if the first signaling also indicates a first quantity and the format of the first quantity of second signaling, the terminal device can determine whether the number of received second signalings reaches the first quantity to confirm whether the received second signalings are complete and without loss. Furthermore, the terminal device can receive the second signaling based on the format indicated by the first signaling, further improving reception efficiency, accuracy, and reliability.

[0331] Relationship 3: The first number of second signalings includes p (a positive integer) levels of second signalings, and the number of second signalings in each level is 1.

[0332] The first signaling includes the signaling parameters and / or quantity of the first-level second signaling. The i-th-level second signaling includes the signaling parameters and / or quantity of the i+1-th-level second signaling, where i+1 is a positive integer greater than 1 and less than or equal to p.

[0333] Therefore, it can be considered that the first signaling is associated with the first-level second signaling, the first-level second signaling is associated with the first signaling and the second-level second signaling, and the i-th level second signaling is associated with the i-1th level second signaling (if any) and the i+1th level second signaling.

[0334] As shown in Figure 6, the first number is 3, p is 3, the first signaling indicates the physical resource information of the second signaling 1, the second signaling 1 indicates the physical resource information of the second signaling 2, and the second signaling 2 indicates the physical resource information of the second signaling 3.

[0335] The terminal device receives the second signaling 1 based on the physical resource information indicated by the first signaling, then receives the second signaling 2 based on the physical resource information indicated by the second signaling 1, and finally receives the second signaling 3 based on the physical resource information indicated by the second signaling 2. Therefore, the terminal device does not need to perform blind detection, which is conducive to saving power consumption.

[0336] Furthermore, if, in addition to the physical resource information, information such as quantity and format is also indicated, the terminal device can also confirm whether the received second signaling is complete and without loss, thereby improving reception efficiency, accuracy and reliability.

[0337] In other words, there is a "hierarchical relationship" or "dependency relationship" between the first signaling under relationship 2 and the first number of second signalings, and the physical resource information of each second signaling is indicated by another second signaling or the first signaling. Since the first information in the first signaling only needs to include the signaling parameters of one second signaling, and the first information in a second signaling only needs to include the signaling parameters of another second signaling, the overhead of the first signaling and the second signaling can be reduced, saving transmission resources. However, precisely because there is an association between the various second signalings, the success or failure of the reception of the second signaling of the i-th level will affect the reception of the second signaling of the i+1th level, which may result in reduced scheduling reliability, increased transmission failure rate, and reduced system efficiency.

[0338] Relationship 4: The first number of second signalings includes k (a positive integer) levels of second signalings, and the number of second signalings in each level is at least one.

[0339] The first signaling includes at least one signaling parameter and / or quantity of a first-level second signaling. An i-th-level second signaling includes at least one signaling parameter and / or quantity of an i+1-th-level second signaling, where i+1 is a positive integer greater than 1 and less than or equal to k.

[0340] Therefore, it can be considered that the first signaling is associated with at least one first-level second signaling, a first-level second signaling is associated with the first signaling and at least one second-level second signaling, and an i-th level second signaling is associated with an i-1-th level second signaling (if any) and at least one i+1-th level second signaling.

[0341] As shown in Figure 7, the first quantity is 5, k is 2, the first signaling indicates the physical resource information of 2 first-level second signalings (second signaling 1 and second signaling 2), the second signaling 1 indicates the physical resource information of 2 second-level second signalings (second signaling 3 and second signaling 4), and the second signaling 2 indicates the physical resource information of 1 second-level second signaling (second signaling 5).

[0342] The terminal device receives second signaling 1 and second signaling 2 based on the physical resource information indicated by the first signaling, then receives second signaling 3 and second signaling 4 based on the physical resource information indicated by the second signaling 1, and receives second signaling 5 based on the physical resource information indicated by the second signaling 2. Therefore, the terminal device does not need to perform blind detection, which is conducive to saving power consumption.

[0343] Furthermore, if, in addition to the physical resource information, information such as quantity and format is also indicated, the terminal device can also confirm whether the received second signaling is complete and without loss, thereby improving reception efficiency, accuracy and reliability.

[0344] Since the first information in the first signaling only needs to include some signaling parameters of the second signaling, the first information in a second signaling only needs to include signaling parameters of at least one other second signaling, the overhead of the first signaling and the second signaling can be reduced, saving transmission resources.

[0345] Furthermore, while there is a hierarchical or dependency relationship between the first signaling and the first number of second signaling messages under Relationship 3, not all second signaling messages are associated with each other. Failure to receive some second signaling messages will not affect the reception of all other second signaling messages. Compared to Relationship 2, Relationship 3 offers higher reliability, a lower transmission failure rate, and improved system efficiency.

[0346] It should be understood that the above four association relationships can be used individually or in combination. For example, relationship 1 and relationship 2 can be used in combination, relationship 1 and relationship 3 can be used in combination, relationship 1 and relationship 4 can be used in combination, relationship 2 and relationship 3 can be used in combination, relationship 2 and relationship 4 can be used in combination, and so on.

[0347] It should be understood that the above five aspects can be used alone or in combination, so that the method provided in the embodiment of the present application has high robustness and flexibility. For example, the first number in step 210 adopts the design in "1. Related content of the first number", and the first signaling in step 210 adopts the design in "2. Related content of the first signaling", so that the method provided in the embodiment of the present application has high reliability, and the first signaling transmitted between the network device and the terminal device has high flexibility. For another example, the second signaling in step 230 adopts the design in "3. Related content of the second signaling", so that the first signaling transmitted between the network device and the terminal device has high flexibility and scheduling efficiency. For another example, the first signaling in step 210 and the second signaling in step 230 adopt the design in "4. Related content of the physical resource relationship between the first signaling and the second signaling", and the design in "5. The association relationship between the first signaling and the second signaling", so that the transmission of the first signaling and the second signaling has high flexibility. The embodiments of the present application can be freely combined with the above five aspects to adapt to the transmission and scheduling requirements in various communication scenarios. The beneficial effects produced by each design when used alone are also effective when used in combination. Not all combinations are listed here one by one.

[0348] FIG8 is a flow chart of a scheduling method provided by some exemplary embodiments of the present application. The method is schematically illustrated by taking the network device 110 shown in FIG1 as an example. The method includes at least some of the following steps:

[0349] Step 810: Send a first signaling, where the indication information of the first signaling includes a first quantity;

[0350] The network device sends a first signaling to the terminal device. The first signaling is sent in a unicast, multicast or broadcast manner.

[0351] In some embodiments, the first quantity is the number of second signalings that the network device expects the terminal device to receive; or it is understood that the first quantity is the number of second signalings that the network device instructs the terminal device to receive; or it is understood that the first quantity is the number of second signalings that the terminal device needs to receive; or it is understood that the first quantity is the number of second signalings sent by the network device to the terminal device; or it is understood that the first quantity is the number of second signalings associated with the first signaling.

[0352] The second signaling associated with the first signaling can be understood as the second signaling used in conjunction with the first signaling; or understood as the second signaling that schedules a second number of physical channels or cells together with the first signaling.

[0353] Among them, the physical channel includes at least one of PDSCH, PUSCH, PUCCH, PSSCH, PSCCH, etc.

[0354] In some embodiments, the first number is explicitly indicated by the first signaling, or the first number is implicitly indicated by the first signaling.

[0355] In some embodiments, the specific manner of implicit indication may be agreed upon by a communication protocol, configured by a network device, or determined by negotiation between the network device and the terminal device.

[0356] In some embodiments, the first signaling is also called basic signaling, main signaling, first-level signaling, level 0 signaling, etc.

[0357] Step 830: Send a first quantity of second signaling.

[0358] The network device sends a second signaling to the terminal device. The second signaling is sent in a unicast, multicast or broadcast manner.

[0359] In some embodiments, the second signaling is also called extended signaling, slave signaling, auxiliary signaling, i-th level signaling, etc.

[0360] In some embodiments, the first signaling and the second signaling can be understood as control signaling, scheduling signaling, or authorization signaling. Exemplarily, in an uplink or downlink transmission scenario, the first signaling and / or the second signaling is DCI; in a sidelink transmission scenario, the first signaling and / or the second signaling is SCI.

[0361] The first signaling and the second signaling are used to schedule a second number of physical channels or cells, where the second number is a positive integer, that is, the number of scheduled physical channels or scheduled cells is the second number.

[0362] The first signaling and the second signaling are used to schedule a second number of physical channels or cells, where the second number is a positive integer.

[0363] In some embodiments, the network device sends the first signaling and the second signaling.

[0364] In some embodiments, the network device sends the first signaling first and then sends the second signaling.

[0365] In some embodiments, the information indicated by the first signaling and the second signaling overlap; or, the information indicated by the first signaling and the second signaling are different.

[0366] In some embodiments, the formats of the first signaling and the second signaling are different, that is, the information field of the first signaling is different from the information field of the second signaling.

[0367] In some embodiments, the scheduling information of a physical channel among the second number of physical channels is carried by a first signaling, or carried by a second signaling, or carried by a first signaling and a second signaling, or carried by multiple second signalings, or carried by a first signaling and multiple second signalings.

[0368] In some embodiments, the scheduling information of a cell among the second number of cells is carried by a first signaling, or carried by a second signaling, or carried by a first signaling and a second signaling, or carried by multiple second signalings, or carried by a first signaling and multiple second signalings.

[0369] In some embodiments, the network device may further configure first configuration information to the terminal device. The first configuration information includes at least one of the maximum number of codewords, the number of CBGs, the transmission direction, the time domain resources, and the maximum number of HARQ processes. The specific content can be referred to above and will not be repeated here.

[0370] In some embodiments, the network device may further configure second configuration information to the terminal device. The second configuration information is used to configure the payload of the second signaling and / or the maximum value of the payload of the second signaling.

[0371] In summary, the method provided by the embodiment of the present application supports the network device to schedule the second number of physical channels or cells through the first signaling and the second signaling. The total number of bits of the first signaling and the second signaling can exceed the coding capacity limit of the single signaling in the related art, thereby realizing the simultaneous scheduling of more physical channels or cells and improving the scheduling efficiency. Moreover, since the first number has been indicated in the first signaling, when the terminal device receives the second signaling, it can not only confirm whether the received second signaling has reached the first number, thereby improving reliability, but also stop blind detection after receiving the first number of second signalings, thereby avoiding power consumption waste caused by meaningless blind detection. In addition, when the first signaling and the second signaling are used to schedule the second number of physical channels or cells, if there is public information corresponding to the scheduled physical channels or scheduled cells in the first signaling and the second signaling, then the larger the value of the second number, the higher the utilization efficiency of the transmission resources corresponding to the first signaling and the second signaling.

[0372] FIG9 is a flow chart of a scheduling method provided by some exemplary embodiments of the present application. The method is schematically illustrated by taking the network device 110 shown in FIG1 as an example. The method includes at least some of the following steps:

[0388] The relevant contents involved in step 920 can be found in the previous text and will not be repeated here.

[0389] Step 930: Determine a second number of physical channels or cells;

[0390] In some embodiments, the network device determines the second number of physical channels or cells based on its own transmission requirements and / or a scheduling request (SR) from the terminal device. That is, the network device determines which physical channels or cells need to be scheduled and the number of physical channels or cells that need to be scheduled.

[0391] Here, need to be scheduled may be understood as expectation to be scheduled, or request to be scheduled.

[0395] The network device sends a first signaling to the terminal device. The first signaling is sent in a unicast, multicast or broadcast manner.

[0396] In some embodiments, the network device explicitly indicates the first quantity through a first signaling, or implicitly indicates the first quantity through a first signaling, wherein the first quantity is an integer greater than or equal to 0.

[0397] In some embodiments, the specific manner of implicit indication may be agreed upon by a communication protocol, configured by a network device, or determined by negotiation between the network device and the terminal device.

[0398] The relevant contents involved in step 940 can be found in the previous text and will not be repeated here.

[0399] Step 950: Send a first quantity of second signaling;

[0400] The network device sends a second signaling to the terminal device. The second signaling is sent in a unicast, multicast or broadcast manner.

[0401] The first signaling and the second signaling are used to schedule a second number of physical channels or cells, where the second number is a positive integer.

[0402] In some embodiments, the network device sends the first signaling and the second signaling simultaneously; or, the network device sends the first signaling first and then sends the second signaling.

[0403] In some embodiments, the information indicated by the first signaling and the second signaling overlap; or, the information indicated by the first signaling and the second signaling are different.

[0404] In some embodiments, the formats of the first signaling and the second signaling are different, that is, the information field of the first signaling is different from the information field of the second signaling.

[0405] In some embodiments, the scheduling information of a physical channel among the second number of physical channels is carried by a first signaling, or carried by a second signaling, or carried by a first signaling and a second signaling, or carried by multiple second signalings, or carried by a first signaling and multiple second signalings.

[0406] In some embodiments, the scheduling information of a cell among the second number of cells is carried by a first signaling, or carried by a second signaling, or carried by a first signaling and a second signaling, or carried by multiple second signalings, or carried by a first signaling and multiple second signalings.

[0407] The relevant contents involved in step 950 can be found in the previous text and will not be repeated here.

[0408] Step 960: Transmit on a second number of physical channels or cells.

[0409] In some embodiments, the network device sends at least one of data, system messages, control information, reference signals, etc. to the terminal device on a second number of physical channels or cells.

[0410] In some embodiments, the network device receives at least one of data, control information, reference signals, etc. from the terminal device on a second number of physical channels or cells.

[0411] It should be understood that in the embodiments of the present application, steps 910, 920, 930, and 960 are optional steps. The above steps can be freely combined or split. For example, step 910 and step 920 can be implemented as one step, that is, step 910 and step 920 can be combined into one step; step 910, step 920, and step 960 can be implemented as one step; step 940 and step 950 can be implemented as one step; and so on. The execution order of each step can be changed according to actual circumstances. For example, step 920 can be performed before step 910; step 960 can be performed before step 940; step 960 can be performed before step 910 and / or step 920; and so on. The above steps can be used individually or in combination, for example: step 910 can be implemented as a configuration method alone; step 920 can be implemented as a configuration method alone; step 910 and step 920 can be combined to implement a configuration method; step 960 can be implemented as a transmission method alone; step 960, step 910 and step 920 can be combined to implement a transmission method; and so on.

[0412] In summary, the method provided by the embodiment of the present application supports the network device to flexibly design or configure the first signaling and the second signaling, so that the scheduling of the second number of physical channels or cells has higher flexibility. Moreover, since the scheduling of the physical channel or cell is jointly implemented by the first signaling and the second signaling, the total number of bits of the first signaling and the second signaling can exceed the coding capacity limit of the single signaling in the related art, thereby realizing the simultaneous scheduling of more physical channels or cells and improving the scheduling efficiency. Moreover, since the first number has been indicated in the first signaling, when the terminal device receives the second signaling, it can confirm whether the received second signaling has reached the first number, thereby improving reliability, and can stop blind detection after receiving the first number of second signalings, thereby avoiding power consumption waste caused by meaningless blind detection. In addition, when the first signaling and the second signaling are used to schedule the second number of physical channels or cells, if there is public information corresponding to the scheduled physical channel or the scheduled cell in the first signaling and the second signaling, then the larger the value of the second number, the higher the utilization efficiency of the transmission resources corresponding to the first signaling and the second signaling.

[0413] FIG10 is a flow chart of a scheduling method provided by some exemplary embodiments of the present application. The method is illustrated by taking the network device 110 and the terminal device 120 shown in FIG1 as an example. The method includes at least some of the following steps:

[0414] Step 1001: The terminal device sends an SR to the network device;

[0415] The terminal device requests uplink transmission resources from the network device, including PUCCH resources and / or PUSCH resources.

[0416] Step 1002: The network device sends a first signaling to the terminal device;

[0417] The indication information of the first signaling includes a first quantity. Exemplarily, the first quantity is 3.

[0418] In some embodiments, the first signaling includes at least one of the first information, the second information, and the third information. For example, the first signaling includes the first information and the second information, or the first signaling includes the first information, the second information, and the third information. This embodiment is described using the example of the first signaling including the first information and the second information.

[0419] The first information includes signaling parameters for two second signalings. For details about the signaling parameters, refer to the previous text. For example, the two second signalings are DCI 1 and DCI 2. The first information indicates the formats of DCI 1 and DCI 2, respectively, and uniformly indicates the time-frequency resources and transmission parameters of DCI 1 and DCI 2.

[0420] Exemplarily, the first signaling and the second signaling are used to schedule five physical channels, including four downlink physical channels and one uplink physical channel. The eight physical channels are CH1, CH2, CH3, CH4, and CH5.

[0421] Exemplarily, the first signaling is DCI 0.

[0422] Step 1003: The terminal device receives the first signaling;

[0423] After receiving the first signaling, the terminal device decodes it and obtains the information included in the first signaling.

[0424] Step 1004: The network device sends a second signaling to the terminal device;

[0425] The network device sends a first quantity of second signaling.

[0426] In some embodiments, the time domain resources occupied by the first number of second signalings may be the same or different. The interval between the time domain resources occupied by the first number of second signalings and the time domain resources occupied by the first signaling is less than a first threshold.

[0427] In some embodiments, the second signaling includes at least one of identification information, first information, and third information.

[0428] Illustratively, the first number of second signalings sent by the network device includes second signaling 1, second signaling 2, and second signaling 3. The following uses the example where second signaling 1 is DCI 1, second signaling 2 is DCI 2, and second signaling 3 is DCI 3 as an example for illustrative description, but does not mean to limit the second signaling.

[0429] Step 1005: The terminal device receives the second signaling 1 and the second signaling 2;

[0430] After receiving the second signaling 1 and the second signaling 2, the terminal device decodes them respectively to obtain the information included in the second signaling 1 and the second signaling 2 respectively.

[0431] Exemplarily, DCI 1 includes the following information: DCI 1 identifier, first signaling identifier, CH1 identifier, CH2 identifier, CH1 scheduling information, CH2 scheduling information, and signaling parameters of DCI 3. DCI 3 is the second signaling.

[0432] Exemplarily, DCI 2 includes the following information: an identifier of DCI 2, an identifier of the first signaling, an identifier of CH3, an identifier of CH4, scheduling information of CH3, and a first part of scheduling information of CH4.

[0433] Based on the identifier of DCI 1 and the identifier of DCI 2, the terminal device compares the first number (3) indicated by the first signaling and determines that there is still a second signaling that has not been received, that is, the complete scheduling information has not been obtained yet.

[0434] Step 1006: The terminal device receives the second signaling 3;

[0435] Exemplarily, the terminal device receives DCI 3 based on the signaling parameters of DCI 3 included in DCI 1. Exemplarily, the terminal device receives DCI 3 on the physical resources of DCI 3 indicated by DCI 1, so there is no need to perform blind detection on DCI 3, thereby saving power consumption.

[0436] Exemplarily, DCI 3 includes the following information: an identifier of DCI 3, an identifier of the first signaling, an identifier of CH4, an identifier of CH5, the second part of scheduling information of CH4, and scheduling information of CH5.

[0437] For example, the terminal device compares the identifiers of DCI 1, DCI 2, and DCI 3 with the first quantity (3) indicated by the first signaling to determine that all second signaling corresponding to the current scheduling has been received, that is, the complete scheduling information required for the current scheduling has been obtained. It can be seen that the method provided by this embodiment ensures both scheduling efficiency and scheduling reliability.

[0438] Step 1007: The terminal device and the network device transmit on the scheduled physical channel.

[0439] Exemplarily, the terminal device sends uplink data or uplink control information (UCI) to the network device on an uplink physical channel among the five physical channels scheduled by the first signaling and the second signaling. Exemplarily, the terminal device sends a HARQ-ACK codebook or channel state information (CSI) on the PUCCH scheduled by the first signaling and the second signaling. Accordingly, the network device receives the HARQ-ACK codebook, CSI, or uplink data, etc. sent by the terminal device on the uplink physical channel.

[0440] Illustratively, the network device sends downlink data, DCI, reference signals, etc. to the terminal device on a downlink physical channel among the five physical channels scheduled by the first and second signaling. Correspondingly, the terminal device receives downlink data, DCI, reference signals, etc. sent by the network device on the downlink physical channel.

[0441] In summary, the method provided in the embodiments of the present application supports flexible scheduling of more physical channels or cells through first and second signaling, significantly improving scheduling efficiency while also providing high reliability and flexibility, saving power consumption and transmission resources. This results in higher transmission efficiency, better stability, greater flexibility, and less resource waste between network devices and terminal devices.

[0514] In some embodiments, the third processing module 1203 is also used to determine the payload of the second signaling and / or the maximum value of the payload of the second signaling based on at least one of the following: the number of PRBs of the scheduled physical channel corresponding to the second signaling; the number of CBGs of the scheduled physical channel corresponding to the second signaling; the number of codewords of the scheduled physical channel corresponding to the second signaling; the precoding information of the scheduled physical channel corresponding to the second signaling; the number of PRBs of the scheduled cell corresponding to the second signaling; the number of CBGs of the scheduled cell corresponding to the second signaling; the number of codewords of the scheduled cell corresponding to the second signaling; and the precoding information of the scheduled cell corresponding to the second signaling.

[0515] In some embodiments, the interval between the time domain resources occupied by the second signaling and the time domain resources occupied by the first signaling is less than a first threshold;

[0516] The first threshold is agreed upon by a communication protocol, configured by a network device, or determined by the terminal device and the network device.

[0521] In summary, the device provided by this embodiment supports the flexible design or configuration of the first signaling and the second signaling, so that the scheduling of the second number of physical channels or cells has high flexibility. Moreover, since the scheduling of the physical channels or cells is jointly implemented by the first signaling and the second signaling, the total number of bits of the first signaling and the second signaling can exceed the coding capacity limit of a single signaling in the related art, thereby realizing the simultaneous scheduling of more physical channels or cells and improving the scheduling efficiency. Moreover, since the first number has been indicated in the first signaling, when the terminal device receives the second signaling, it can not only confirm whether the received second signaling has reached the first number, thereby improving reliability, but also stop blind detection after receiving the first number of second signalings, thereby avoiding power consumption waste caused by meaningless blind detection. In addition, when the first signaling and the second signaling are used to schedule the second number of physical channels or cells, if there is public information corresponding to the scheduled physical channels or scheduled cells in the first signaling and the second signaling, then the larger the value of the second number, the higher the utilization efficiency of the transmission resources corresponding to the first signaling and the second signaling.
