Technical Field

[0003] With the continuous development of wireless communication networks, wireless communication has played an increasingly important role in people's lives. At present, the fifth generation mobile communication technology (5th Generation, 5G) can support the next generation NodeB (gNB) to simultaneously schedule two physical downlink shared channels (PDSCH) or physical uplink shared channels (PUSCH) located in two component carriers (CC) through two downlink control information (DCI) to improve the system throughput. However, scheduling two PDSCHs or PUSCHs simultaneously through two DCIs will increase the number of DCIs in the system cell, causing the physical downlink control channel (PDCCH) carrying the DCI to be blocked. To prevent this from happening, the industry has proposed a solution to schedule two PDSCHs or PUSCHs located in different cells through one DCI. However, this solution is not mature at present, and it will cause resource waste and performance degradation caused by the excessive size of the DCI. Summary of the invention

[0028] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0029] The maturity of 5G technology will further support three major application scenarios, including enhanced mobile broadband, high reliability and ultra-low latency communications, and large-scale machine communications. In terms of system performance, 5G technology will have key capability indicators such as a peak rate of 10-20 Gbit / s, a connection density of 1 million per square kilometer, an air interface latency of 1ms, a mobility support of 500 kilometers per hour (km / h), and a traffic density of 10 megabits per second (Mbit / s) per square meter. At present, 5G technology can support gNB to simultaneously schedule two PDSCHs or PUSCHs located in two CCs through two DCIs to improve the system throughput. However, scheduling two PDSCHs or PUSCHs simultaneously through two DCIs will increase the number of DCIs in the system cell, causing blocking of the PDCCH carrying the DCI.

[0030] To prevent this from happening, the industry has proposed a solution to schedule two PDSCHs or PUSCHs in different cells through one DCI, so as to reduce the number of DCIs sent in the system cell and reduce the blocking rate of PDCCH. However, in this solution, since one DCI needs to schedule two PDSCHs or PUSCHs, the DCI needs to carry information of two CCs at the same time. The increase in the amount of information carried also causes the size of the new DCI to become larger, resulting in resource waste and performance degradation caused by the DCI size being too large.

[0031] The embodiment of the present application provides a mobile communication network (including but not limited to 5G), the network architecture of which may include terminal devices and access network devices. The terminal device is connected to the access network device wirelessly, and the terminal device may be fixed or movable. In the embodiment of the present application, a control signaling transmission and acquisition method, device and storage medium that can run on the above network architecture are provided, which can realize the transmission of control signaling, reduce the overhead of communication equipment, and improve system performance.

[0032] The access network device is an access device that the terminal device accesses to the mobile communication system by wireless means. It can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a gNB in ​​a 5G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc.; it can also be a module or unit that completes some functions of a base station, for example, it can be a centralized unit (CU) or a distributed unit (DU). The embodiments of the present application do not limit the specific technology and specific device form adopted by the access network device. In the present application, the access network device can be referred to as the network device. If there is no special explanation, the network device refers to the access network device.

[0033] The terminal device may also be referred to as a terminal, user equipment (UE), a mobile station, a mobile terminal, etc. The terminal device may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality terminal device, an augmented reality terminal device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in remote surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal device.

[0034] The following describes the control signaling transmission and acquisition method, equipment and its technical effects.

[0035] Figure 1 A flow chart of a control signaling transmission method provided by an embodiment is shown. Figure 1 As shown, the method provided in this embodiment is applicable to a first communication node (such as an access network device), and the method includes the following steps.

[0036] S110. The first communication node sends first control information to the second communication node, where the first control information includes at least one downlink control information DCI sub-field, and at least one DCI sub-field includes priority information.

[0037] In one embodiment, the first control information may be DCI, which is carried by a PDCCH located in a primary cell (PCell) or a secondary cell (SCell) and is used to schedule PDSCH or PUSCH located in at least two cells. The at least two cells are transmitted by carrying data in multiple CCs.

[0038] The first control information includes at least one DCI subfield, and the priority information of the at least one DCI subfield may be confirmed by at least one of the following five methods:

[0039] Method 1: Priority information of at least one DCI subfield is determined by the first communication node according to protocol predefinition.

[0040] Method 2: Priority information of at least one DCI sub-domain is configured by the first communication node according to Radio Resource Control (RRC) signaling.

[0041] Method 3: The priority information of at least one DCI sub-domain within the same functional group is determined based on the priority information of the functional group, and the priority information of the functional group is predefined and determined by the first communication node based on a protocol.

[0042] In method 3, the first communication node divides at least one DCI sub-domain in the DCI into at least one functional group according to the protocol pre-definition, and each functional group contains at least one DCI sub-domain; then determines the priority of each functional group according to the protocol pre-definition, and the priority information of the DCI sub-domains in the same functional group is consistent.

[0043] Method 4: The priority information of at least one DCI sub-domain within the same functional group is determined based on the priority information of the functional group, and the priority information of the functional group is configured by the first communication node based on RRC signaling.

[0044] In method 4, the first communication node divides at least one DCI sub-domain in the DCI into at least one functional group according to the protocol pre-definition, and each functional group contains at least one DCI sub-domain; then configures the priority of each functional group according to RRC signaling, and the priority information of the DCI sub-domains in the same functional group is consistent.

[0045] Method 5: The priority information of at least one DCI sub-domain within the same functional group is configured by the first communication node according to RRC signaling, and the priority information of the functional group is predefined and determined by the first communication node according to the protocol.

[0046] In method 5, the first communication node divides at least one DCI sub-domain in the DCI into at least one functional group according to the protocol pre-definition, and each functional group includes at least one DCI sub-domain; then configures the priority of each functional group according to RRC signaling; finally, configures the priority of the DCI sub-domain in at least one functional group according to RRC signaling, and the priorities of the DCI sub-domains in the same functional group that are not configured with DCI sub-domain priorities by RRC signaling are consistent.

[0047] In one embodiment, in the above methods 1-5, the first communication node or the second communication node discards the DCI subdomain or sets a sharing indication in units of DCI subdomains of the same priority. For example, the first DCI subdomain and the second DCI subdomain belong to the same first functional group, and the priority information of the first functional group is the first priority. Then, the priority information of the first DCI subdomain and the second DCI subdomain is also the same as the first priority. When the first communication node or the second communication node discards the DCI subdomain of the first functional group (i.e., the DCI subdomain of the first priority), the first DCI subdomain and the second DCI subdomain are discarded at the same time or a sharing indication is set.

[0048] In one embodiment, in the above method 3 or method 4, when the DCI subdomain is divided into a plurality of functional groups, the first communication node or the second communication node will discard the DCI subdomain or set a sharing indication in units of functional groups. For example, the first DCI subdomain and the second DCI subdomain belong to the first functional group, and the priority information of the first functional group is the first priority. Then, the priority information of the first DCI subdomain and the second DCI subdomain is also the first priority. When the first communication node or the second communication node discards the DCI subdomain of the first functional group (i.e., the DCI subdomain of the first priority), the first DCI subdomain and the second DCI subdomain are discarded at the same time or a sharing indication is set.

[0049] In one embodiment, when the priorities of the DCI sub-domains are consistent, the first communication node or the second communication node can be distinguished according to the configuration order of the DCI sub-domains or the front-to-back order of the DCI bits where the DCI sub-domains are located. For example, if the priority information of the first DCI sub-domain and the second DCI sub-domain are both the first priority, and the first DCI sub-domain is configured earlier, the first DCI sub-domain will be discarded first or a sharing indication will be set by default.

[0050] In one embodiment, the DCI subfield that is not predefined by the protocol or configured with priority information by RRC signaling has the highest priority; or, the DCI subfield that is not predefined by the protocol or configured with priority information by RRC signaling has the lowest priority. For example, if the priority information of the first DCI subfield and the second DCI subfield are both the first priority, and the third DCI subfield is not predefined by the protocol or configured with priority information by RRC signaling, then the third DCI subfield defaults to the highest priority, that is, the priority of the third DCI subfield is higher than that of the first DCI subfield and the second DCI subfield.

[0051] Figure 2 FIG. 4 is a flow chart showing another control signaling transmission method provided by an embodiment. Figure 2 As shown, the method provided in this embodiment is applicable to a second communication node (such as a terminal device), and the method includes the following steps.

[0052] S210. The second communication node receives first control information sent by the first communication node, where the first control information includes at least one downlink control information DCI sub-field, and at least one DCI sub-field contains priority information.

[0053] In one embodiment, the first control information may be DCI, which is carried by a PDCCH located in a primary cell (PCell) or a secondary cell (SCell) and is used to schedule PDSCH or PUSCH located in at least two cells. The at least two cells are transmitted by carrying data in multiple CCs.

[0054] The first control information includes at least one DCI subfield, and the priority information of the at least one DCI subfield may be confirmed by at least one of the following five methods:

[0055] Method 1: Priority information of at least one DCI subfield is determined by the first communication node according to protocol predefinition.

[0056] Method 2: Priority information of at least one DCI sub-domain is configured by the first communication node according to Radio Resource Control (RRC) signaling.

[0057] Method 3: The priority information of at least one DCI sub-domain within the same functional group is determined based on the priority information of the functional group, and the priority information of the functional group is predefined and determined by the first communication node based on a protocol.

[0058] In method 3, the first communication node divides at least one DCI sub-domain in the DCI into at least one functional group according to the protocol pre-definition, and each functional group contains at least one DCI sub-domain; then determines the priority of each functional group according to the protocol pre-definition, and the priority information of the DCI sub-domains in the same functional group is consistent.

[0059] Method 4: The priority information of at least one DCI sub-domain within the same functional group is determined based on the priority information of the functional group, and the priority information of the functional group is configured by the first communication node based on RRC signaling.

[0060] In method 4, the first communication node divides at least one DCI sub-domain in the DCI into at least one functional group according to the protocol pre-definition, and each functional group contains at least one DCI sub-domain; then configures the priority of each functional group according to RRC signaling, and the priority information of the DCI sub-domains in the same functional group is consistent.

[0061] Method 5: The priority information of at least one DCI sub-domain within the same functional group is configured by the first communication node according to RRC signaling, and the priority information of the functional group is predefined and determined by the first communication node according to the protocol.

[0062] In method 5, the first communication node divides at least one DCI sub-domain in the DCI into at least one functional group according to the protocol pre-definition, and each functional group includes at least one DCI sub-domain; then configures the priority of each functional group according to RRC signaling; finally, configures the priority of the DCI sub-domain in at least one functional group according to RRC signaling, and the priorities of the DCI sub-domains in the same functional group that are not configured with DCI sub-domain priorities by RRC signaling are consistent.

[0063] In one embodiment, in the above methods 1-5, the first communication node or the second communication node discards the DCI subdomain or sets a sharing indication in units of DCI subdomains of the same priority. For example, the first DCI subdomain and the second DCI subdomain belong to the same first functional group, and the priority information of the first functional group is the first priority. Then, the priority information of the first DCI subdomain and the second DCI subdomain is also the same as the first priority. When the first communication node or the second communication node discards the DCI subdomain of the first functional group (i.e., the DCI subdomain of the first priority), the first DCI subdomain and the second DCI subdomain are discarded at the same time or a sharing indication is set.

[0064] In one embodiment, in the above method 3 or method 4, when the DCI subdomain is divided into a plurality of functional groups, the first communication node or the second communication node will discard the DCI subdomain or set a sharing indication in units of functional groups. For example, the first DCI subdomain and the second DCI subdomain belong to the first functional group, and the priority information of the first functional group is the first priority. Then, the priority information of the first DCI subdomain and the second DCI subdomain is also the first priority. When the first communication node or the second communication node discards the DCI subdomain of the first functional group (i.e., the DCI subdomain of the first priority), the first DCI subdomain and the second DCI subdomain are discarded at the same time or a sharing indication is set.

[0065] In one embodiment, when the priorities of the DCI sub-domains are consistent, the first communication node or the second communication node can be distinguished according to the configuration order of the DCI sub-domains or the front-to-back order of the DCI bits where the DCI sub-domains are located. For example, if the priority information of the first DCI sub-domain and the second DCI sub-domain are both the first priority, and the first DCI sub-domain is configured earlier, the first DCI sub-domain will be discarded first or a sharing indication will be set by default.

[0066] In one embodiment, the DCI subfield that is not predefined by the protocol or configured with priority information by RRC signaling has the highest priority; or, the DCI subfield that is not predefined by the protocol or configured with priority information by RRC signaling has the lowest priority. For example, if the priority information of the first DCI subfield and the second DCI subfield are both the first priority, and the third DCI subfield is not predefined by the protocol or configured with priority information by RRC signaling, then the third DCI subfield defaults to the highest priority, that is, the priority of the third DCI subfield is higher than that of the first DCI subfield and the second DCI subfield.

[0067] Figure 3 A schematic diagram of a flow chart of another control signaling transmission method provided by an embodiment is shown, such as Figure 3 As shown, the method provided in this embodiment is applicable to a first communication node (such as an access network device), and the method includes the following steps.

[0068] S310. The first communication node determines a threshold value.

[0069] In one embodiment, the method for the first communication node to determine the threshold value may include any one of the following three methods:

[0070] Method 1: The first communication node determines a threshold value according to a protocol pre-definition.

[0071] For example, the threshold value M may be 84, 85, 90, 100, 108, 109, 150, 192, 193, 200, 216, 217, etc.

[0072] Method 2: The first communication node determines a threshold value candidate set according to protocol pre-definition, and selects a threshold value from the threshold value candidate set through unlimited resource control RRC signaling.

[0073] For example, the threshold candidate set is {M 1 ,M 2 ,…,M i}(i=0,…,n;n≥0), a threshold value M is selected from a threshold value candidate set through RRC signaling, and the threshold value M can be 84, 85, 90, 100, 108, 109, 150, 192, 193, 200, 216, 217, etc.

[0074] Method 3: The first communication node determines the threshold value ratio according to the protocol pre-definition or RRC signaling, and calculates the threshold value according to the second control information basic size and the threshold value ratio.

[0075] For example, the value of the threshold value ratio o is in the range of 0-1, and can be specifically 10%, 15%, 20%, 25%, 30%, 40%, 50%, 60%, 70%, 80% and the like.

[0076] In one embodiment, when the second control information schedules a cell, the basic size of the second control information is N, and the threshold value is When the second control information schedules at least two cells, the basic size of the second control information is N i (i=0,...,n-1), n ​​is the number of cells scheduled by the second control information, the threshold value

[0077] In one embodiment, when the second control information schedules a cell, the basic size of the second control information is N, and the threshold value is When the second control information schedules at least two cells, the basic size of the second control information is N i (i=0,...,n-1), n ​​is the number of cells scheduled by the second control information, the threshold value

[0078] S320. The first communication node determines second control information according to the threshold value, where the second control information includes at least one downlink control information DCI subfield.

[0079] In one embodiment, the second control information may be DCI, which is carried by a PDCCH in a PCell or SCell and is used to schedule PDSCHs or PUSCHs in at least two cells. The at least two cells are carried by multiple CCs for data transmission.

[0080] The second control information includes at least one DCI subdomain, and the at least one DCI subdomain can be configured with priority by the method described in the above embodiment. The DCI subdomain can independently indicate multiple cells or share indications. When indicating independently, the size of the DCI subdomain is equal to the sum of the sizes required for independently indicating each cell. For example, the first DCI subdomain independently indicates the first cell and the second cell, indicating the size of the first cell as a, and indicating the size of the second cell as b, then the size of the first DCI subdomain is a+b. When indicating shared, the size of the DCI subdomain is equal to the maximum value of the sizes required for independently indicating each cell. For example, the first DCI subdomain shares the indication of the first cell and the second cell, independently indicating the size of the first cell as a, and independently indicating the size of the second cell as b, then the size of the first DCI subdomain is max{a,b}.

[0081] In one embodiment, the method for the first communication node to determine the second control information according to the threshold value may include any one of the following eight schemes.

[0082] Scheme 1 includes steps A1 to A5:

[0083] Step A1: The first communication node obtains a target DCI subdomain from the second control information, where the target DCI subdomain is a DCI subdomain with the highest priority among the currently remaining DCI subdomains.

[0084] After a DCI subdomain is used as a target DCI subdomain, it will no longer be used as an object for selecting a target DCI subdomain next time. That is, when step A1 is executed for the first time, the second control information includes all DCI subdomains, and the target DCI subdomain is a DCI subdomain with the highest priority among all DCI subdomains; when step A1 is executed for the Xth time (X≥2), the second control information includes the current remaining DCI subdomains except the target DCI subdomain selected in the previous step, and the target DCI subdomain is a DCI subdomain with the highest priority among the current remaining DCI subdomains.

[0085] Step A2: The first communication node sets the state of the target DCI subfield to an independent indication, calculates the size of the target DCI subfield, and updates the first size of the second control information according to the size of the target DCI subfield.

[0086] The initial value of the first size of the second control information is 0. That is, when step A2 is executed for the first time, the first size of the updated second control information is the size of the target DCI subfield; when step A2 is executed for the Xth time (X≥2), the first size of the updated second control information is the sum of the size of the target DCI subfield selected when step A1 is executed for the Xth time and the first size of the second control information updated when step A1 is executed for the X-1th time.

[0087] Step A3: The first communication node determines whether the first size of the second control information is greater than a threshold value.

[0088] Step A4: if the first size of the second control information is greater than the threshold value, the first communication node modifies the status of the target DCI subdomain to a shared indication and updates the first size of the second control information. If the first size of the updated second control information is not greater than the threshold value, the first communication node returns to execute step A2 of obtaining the next target DCI subdomain and setting the status of the next target DCI subdomain to an independent indication. If the first size of the updated second control information is greater than the threshold value, the first communication node sets the status of the remaining DCI subdomains to a shared indication.

[0089] Step A5: If the first size of the second control information is not greater than the threshold value, the first communication node returns to execute step A2 of obtaining the next target DCI subdomain and setting the status of the next target DCI subdomain to an independent indication until the first size of the second control information is greater than the threshold value.

[0090] Solution 2 includes steps a1 to a5:

[0091] Step a1: The first communication node obtains a target DCI subdomain from the second control information, where the target DCI subdomain is a DCI subdomain with the highest priority among the currently remaining DCI subdomains.

[0092] Step a2: The first communication node sets the state of the target DCI subfield to an independent indication, calculates the size of the target DCI subfield, and updates the first size of the second control information according to the size of the target DCI subfield.

[0093] Step a3: The first communication node determines whether the first size of the second control information is not less than a threshold value.

[0094] Step a4: if the first size of the second control information is not less than the threshold value, the first communication node modifies the status of the target DCI subdomain to a shared indication and updates the first size of the second control information. If the first size of the updated second control information is less than the threshold value, the first communication node returns to execute step A2 of obtaining the next target DCI subdomain and setting the status of the next target DCI subdomain to an independent indication. If the first size of the updated second control information is not less than the threshold value, the first communication node sets the status of the remaining DCI subdomains to a shared indication.

[0095] Step a5: If the first size of the second control information is smaller than the threshold value, the first communication node returns to execute step A2 of obtaining the next target DCI subdomain and setting the status of the next target DCI subdomain to an independent indication until the first size of the second control information is not smaller than the threshold value.

[0096] Scheme 3 includes steps B1 to B5:

[0097] Step B1: The first communication node obtains a target DCI subdomain from the second control information, where the target DCI subdomain is a DCI subdomain with the highest priority among the currently remaining DCI subdomains.

[0098] After a DCI subdomain is used as a target DCI subdomain, it will no longer be used as an object for selecting a target DCI subdomain next time. That is, when step B1 is executed for the first time, the second control information includes all DCI subdomains, and the target DCI subdomain is a DCI subdomain with the highest priority among all DCI subdomains; when step B1 is executed for the Xth time (X≥2), the second control information includes the current remaining DCI subdomains except the target DCI subdomain selected in the previous step, and the target DCI subdomain is a DCI subdomain with the highest priority among the current remaining DCI subdomains.

[0099] Step B2: The first communication node sets the state of the target DCI subfield to an independent indication, calculates the size of the target DCI subfield, and updates the first size of the second control information according to the size of the target DCI subfield.

[0100] The initial value of the first size of the second control information is 0. That is, when step B2 is executed for the first time, the first size of the updated second control information is the size of the target DCI subfield; when step B2 is executed for the Xth time (X≥2), the first size of the updated second control information is the sum of the size of the target DCI subfield selected when step B1 is executed for the Xth time and the first size of the second control information updated when step B1 is executed for the X-1th time.

[0101] Step B3: The first communication node determines whether the first size of the second control information is greater than a threshold value.

[0102] Step B4: if the first size of the second control information is greater than the threshold value, the first communication node modifies the state of the target DCI subdomain to a shared indication and updates the first size of the second control information. If the first size of the updated second control information is not greater than the threshold value, the first communication node returns to execute step B2 of obtaining the next target DCI subdomain and setting the state of the next target DCI subdomain to an independent indication. If the first size of the updated second control information is greater than the threshold value, the first communication node discards the current DCI subdomain and the remaining DCI subdomains.

[0103] Step B5. If the first size of the second control information is not greater than the threshold value, the first communication node returns to execute step B2 of obtaining the next target DCI subdomain and setting the status of the next target DCI subdomain to an independent indication until the first size of the second control information is greater than the threshold value.

[0104] Scheme 4 includes steps b1 to b5:

[0105] Step b1: The first communication node obtains a target DCI subdomain from the second control information, where the target DCI subdomain is a DCI subdomain with the highest priority among the currently remaining DCI subdomains.

[0106] Step b2: The first communication node sets the state of the target DCI subfield to an independent indication, calculates the size of the target DCI subfield, and updates the first size of the second control information according to the size of the target DCI subfield.

[0107] Step b3: The first communication node determines whether the first size of the second control information is not less than a threshold value.

[0108] Step b4: if the first size of the second control information is not less than the threshold value, the first communication node modifies the status of the target DCI subdomain to a shared indication and updates the first size of the second control information. If the first size of the updated second control information is less than the threshold value, the first communication node returns to execute step B2 of obtaining the next target DCI subdomain and setting the status of the next target DCI subdomain to an independent indication. If the first size of the updated second control information is not less than the threshold value, the first communication node discards the current DCI subdomain and the remaining DCI subdomains.

[0109] Step b5. If the first size of the second control information is smaller than the threshold value, the first communication node returns to execute step B2 of obtaining the next target DCI subdomain and setting the status of the next target DCI subdomain to an independent indication until the first size of the second control information is not smaller than the threshold value.

[0110] The difference between the above schemes 1 and 2 and schemes 3 and 4 is that: when the first size of the second control information is greater than the threshold value or when the first size of the second control information is not less than the threshold value, after the first communication node modifies the state of the target DCI subfield to a shared indication, schemes 1 and 2 do not discard the remaining DCI subfields, but set the state of the remaining DCI subfields to a shared indication; schemes 3 and 4 discard part of the DCI subfields. It can be seen that schemes 1 and 2 can ensure the integrity of the DCI subfields, and schemes 3 and 4 can reduce the overhead of the second control information.

[0111] Scheme 5 includes steps C1 to C3:

[0112] Step C1: The first communication node determines the sum of the sizes of all DCI subfields in the second control information.

[0113] Step C2: The first communication node determines whether the sum of the sizes of all DCI sub-fields in the second control information is greater than a threshold value.

[0114] Step C3: If the sum of the sizes of all DCI sub-fields in the second control information is greater than the threshold value, the first communication node discards the DCI sub-fields with low priority in order of priority until the sum of the sizes of the remaining DCI sub-fields is no greater than the threshold value.

[0115] Scheme 6 includes steps c1 to c3:

[0116] Step c1: The first communication node determines the sum of the sizes of all DCI subfields in the second control information.

[0117] Step c2: The first communication node determines whether the sum of the sizes of all DCI subfields in the second control information is not less than a threshold value.

[0118] Step c3: If the sum of the sizes of all DCI subfields in the second control information is not less than the threshold value, the first communication node discards the DCI subfields with low priority in order of priority until the sum of the sizes of the remaining DCI subfields is less than the threshold value.

[0119] Scheme 7 includes steps D1 to D3:

[0120] Step D1: The first communication node determines the sum of the sizes of all DCI subfields in the second control information.

[0121] Step D2: The first communication node determines whether the sum of the sizes of all DCI sub-fields in the second control information is greater than a threshold value.

[0122] Step D3: If the sum of the sizes of all DCI sub-fields in the second control information is greater than the threshold value, the first communication node sets the status of the DCI sub-field with a low priority to a shared indication in order of priority, and updates the sum of the sizes of all DCI sub-fields until the sum of the sizes of all DCI sub-fields after the update is no greater than the threshold value.

[0123] Since the status of all DCI subdomains can be independent indications, shared indications, or both independent indications and shared indications, therefore, for the case where the status of all DCI subdomains can be independent indications, the first communication node can set the status of the DCI subdomains with low priority to shared indications in order of priority, and update the sum of the sizes of all DCI subdomains; for the case where the status of all DCI subdomains has both independent indications and shared indications, the first communication node can set the status of the DCI subdomains with low priority and independent indication in order of priority to shared indications, and update the sum of the sizes of all DCI subdomains.

[0124] Scheme 8 includes steps d1 to d3:

[0125] Step d1: The first communication node determines the sum of the sizes of all DCI subfields in the second control information.

[0126] Step d2: The first communication node determines whether the sum of the sizes of all DCI subfields in the second control information is not less than a threshold value.

[0127] Step d3: If the sum of the sizes of all DCI sub-fields in the second control information is not less than the threshold value, the first communication node sets the status of the DCI sub-field with a low priority to a shared indication in order of priority, and updates the sum of the sizes of all DCI sub-fields until the sum of the sizes of all DCI sub-fields after the update is less than the threshold value.

[0128] In one embodiment, for step C1 in the above scheme 5, step c1 in the above scheme 6, step D1 in the above scheme 7, and step d1 in the above scheme 8, any one of the following four methods may be used for determination:

[0129] The first communication node determines that the status of all DCI sub-fields is an independent indication according to the protocol pre-definition, and determines the sum of the sizes of all DCI sub-fields; or,

[0130] The first communication node determines that the status of all DCI sub-fields is a shared indication according to the protocol pre-definition, and determines the sum of the sizes of all DCI sub-fields; or,

[0131] The first communication node determines, according to the protocol pre-definition, that the state of at least one DCI subfield is an independent indication, the state of the remaining DCI subfields is a shared indication, and determines the sum of the sizes of all DCI subfields; or,

[0132] The first communication node determines, according to high-layer signaling, that the state of at least one DCI sub-field is an independent indication, that the state of the remaining DCI sub-fields is a shared indication, and determines the sum of the sizes of all DCI sub-fields.

[0133] S330. The first communication node sends second control information to the second communication node.

[0134] The second control information obtained by determining the threshold value can reduce the control signaling overhead, eliminate redundant indications, and alleviate the situation where the overhead increases exponentially when one DCI schedules two PDSCHs or PUSCHs at the same time, ensuring that the PDCCH blocking rate does not increase excessively and at the same time ensuring the basis for the flexibility of DCI indications. It meets the requirements of a one-modulation-multiple communication system and improves the forward compatibility of the entire system.

[0135] Some exemplary embodiments are listed below to illustrate the present invention. Figure 3 The control signaling transmission method provided herein and the following exemplary embodiments may be performed individually or in combination.

Then, the first communication node determines a threshold value M (e.g., 84, 85, 90, 100, 108, 109, 150, 192, 193, 200, 216, 217, etc.) according to the protocol pre-definition, and determines the first DCI subdomain from the second control information, sets the state of the first DCI subdomain to an independent indication, calculates the size a of the first DCI subdomain, and updates the first size of the second control information to a; the first communication node determines whether a is greater than the threshold value M; if a is greater than the threshold value M, the first communication node modifies the state of the first DCI subdomain to a shared indication, and updates the first size of the second control information to c, and further compares Compare whether c is greater than the threshold value M. If c is not greater than the threshold value M, the first communication node returns to execute the step of determining the second DCI subdomain from the second control information. If c is greater than the threshold value M, the first communication node further sets the status of the second DCI subdomain and the third DCI subdomain to a shared indication. If a is not greater than the threshold value M, the first communication node returns to execute the step of determining the second DCI subdomain from the second control information, setting the status of the second DCI subdomain to an independent indication, calculating the size b of the second DCI subdomain, and updating the first size of the second control information to a+b, until the first size of the second control information is greater than the threshold value M.

Then, the first communication node determines the threshold value candidate set {M 1 ,M 2 ,…,M i}(i=0,…,n;n≥0), select a threshold value M (e.g., 84, 85, 90, 100, 108, 109, 150, 192, 193, 200, 216, 217, etc.) from the threshold value candidate set through RRC signaling, determine the first DCI subdomain from the second control information, set the state of the first DCI subdomain to an independent indication, calculate the size a of the first DCI subdomain, and update the first size of the second control information to a; the first communication node determines whether a is greater than the threshold value M; if a is greater than the threshold value M, the first communication node modifies the state of the first DCI subdomain to a shared indication, and updates the first size of the second control information.

If a is not greater than the threshold value M, the first communication node returns to execute the step of determining the second DCI subdomain from the second control information, setting the status of the second DCI subdomain to an independent indication, calculating the size b of the second DCI subdomain, and updating the first size of the second control information to a+b, until the first size of the second control information is greater than the threshold value M.

Then, the first communication node determines the threshold value proportion o (e.g., 10%, 15%, 20%, 25%, 30%, 40%, 50%, 60%, 70%, 80%, etc.) according to the protocol pre-defined or RRC signaling, and calculates the threshold value M according to the second control information basic size and the threshold value proportion.
