[0048] Embodiments of the present application can be used in wireless networks of different systems. The radio access network may include different communication nodes in different systems.

As Figure 2 shown, the wireless network system 100 includes a base station 101, user equipment 110, user equipment 120, and user equipment 130. The base station 101 performs wireless communication with the user equipment 110, the user equipment 120, and the user equipment 130 respectively.

[0049] In embodiments of the present application, the base station can be a device capable of communicating with user equipment. The base station can be any device with wireless transceiver functions. Including but not limited to: base station NodeB, evolved base station eNodeB, base station in a 5G communication system, base station in a future communication system, access node in a WiFi system, wireless relay node, wireless backhaul node, etc. The base station can also be a radio controller in a cloud radio access network (CRAN) scenario; the base station can also be a small station, a transmission reference point (TRP), etc. Embodiments of the present application do not limit this.

[0051] In the embodiments of the present application, generally speaking, if not otherwise specified, it includes 1 UE and at least two TRPs (or one TRP includes two panels). The repeated PDCCH or PDSCH comes from two different TRPs, and they can be on different CCs or BWPs, or on the same CC or BWP.

[0052] In an exemplary embodiment, Figure 1 It is a schematic flowchart of an information enhancement method provided by the present application. This method can be applied to the case of PDCCH repeated transmission in a Multi-TRP / Pannel scenario. This method can be executed by the information enhancement device provided by the present application, and the information enhancement device can be implemented by software and / or hardware and integrated on a user equipment (UE).

[0053] As Figure 1 shown, the information enhancement method provided by the embodiments of the present application mainly includes steps S110 and S120.

[0054] S110. Determine a first DCI subset and a second DCI subset in a downlink control information DCI set, where the first DCI subset includes N repeated DCIs, and the second DCI subset includes M - N non-repeated DCIs; N is an integer greater than 1, and M is an integer greater than N.

[0055] Among them, DCI refers to the information carried in the PDCCH. The fields and the content in the fields included in different types of DCIs may be different.

[0056] For example: The Downlink assignment index (DAI) is used to indicate that there are multiple subframes containing downlink transmissions within the feedback time window of Hybrid Automatic Repeat Request (HARQ), to prevent the UE from possibly incorrectly feedbacking an acknowledgment message ACK when some DCIs are lost. Currently, only the DAI field exists in DCI format 0_1 and 1_1 in the NR protocol.

[0057] Another example: The Redundancy version (RV) represents the starting position of fetching data from the buffer. Different RV version data can be incrementally merged to improve the decoding correct rate. Currently, only the RV field exists in DCI format 0_1, 0_0, 1_0, and 1_1 in the NR protocol.

[0058] For another example: In DCI format 0_0, 4 bits in the time domain resource assignment (TDRA) field are used to index the slot offset K2, the starting symbol position S within the slot, and the symbol length L of the scheduled PUSCH relative to the DCI; in DCI format 1_0, 4 bits in the TDRA field are used to index the slot offset K0, the starting symbol position S within the slot, and the symbol length L of the scheduled PDSCH relative to the DCI.

[0059] The PDCCH can send downlink scheduling information to the UE to indicate that the UE receives the PDSCH; it can also send uplink scheduling information to the UE to indicate that the UE sends the Physical Uplink Shared Channel (PUSCH); it can also send power control commands for the Physical Uplink Control Channel (PUCCH), PUSCH, and Sounding reference signal (SRS); it can also notify the UE of the slot format, etc.

[0060] The Control Resource Set (CORESET) consists of one or more Control Chanel Elements (CCEs) and represents the time-frequency resource positions where the base station may send the PDCCH. However, the UE does not know which form of DCI the PDCCH carries, nor does it know on which candidate CCE the DCI is transmitted. The UE needs to blindly decode all possible DCI formats on CCEs with different aggregation levels. To reduce the number of blind decoding times, the concept of SearchSpace (SS) is introduced. The SS is composed of a set of CCEs with a given aggregation level. The base station can configure one or more SSs for the UE. The time domain opportunity occasion is determined by the monitoringSlotPeriodicityAndOffset in the SS and represents the time domain position where the base station may send the PDCCH. The Componet Carrier (CC) represents the subcarrier and indicates the frequency domain position.

[0061] Based on the base station configuration information, the UE knows its own SS. First, it attempts to perform a Cyclic Redundancy Check (CRC) on the CCEs within its own SS using the corresponding Radio Network Temporary Identifier (RNTI), possible DCI format, and possible aggregation level. If the check is successful, the UE knows that the information is what it needs and further decodes the content in the DCI.

[0062] The UE blindly detects the DCI on the corresponding Search Space (SS) in the order of time domain first and then frequency domain to obtain the Downlink assignment index (DAI). Since there are the same DAI values in the repeated DCI content, after blind decoding, the DAI value obtained may violate the established rules, and the UE may misunderstand and think that a missed detection has occurred. That is, when the UE blindly decodes the DCI, it cannot guarantee the correct demodulation of all DCIs, and it is necessary to consider the detection situation of the repeated DCI and how to solve the problem of DAI misalignment.

[0063] The DCI set includes M DCIs, where the M DCIs include N repeated DCIs and M - N non-repeated DCIs; the first DCI subset contains N repeated DCIs, where M is an integer greater than N. In an exemplary embodiment, the method further includes: receiving the association relationship of the pre-configured N repeated DCIs, and the association relationship is used to determine the repeated DCIs.

[0064] The association relationship of the configured N repeated DCIs includes at least one of the following:

[0065] Each repeated DCI adds an SSREF field on the search space SS, where the content in the SSREF field is not the search space identifier SSID of the current DCI;

[0066] Each repeated DCI adds a CORESETREF field on the control channel resource set CORESET, where the content in the CORESETREF field is not the control channel resource set identifier CORESETID of the current DCI.

[0067] Predefined high-layer repetition signaling rules, where the repetition signaling rules include at least one of the following: the same first information element is configured on the SS, where the first information element includes at least one of the following: first duration, monitoring time slot period, monitoring time slot period offset, number of candidate PDCCHs, DCI format, symbol position within the monitoring time slot; the same second information element is configured on the CORESET, where the second information element includes at least one of the following: second duration, control channel element to resource element group mapping type, frequency domain resource, interleaving size, scrambling ID of PDCCH DMRS, precoding granularity, transmission control information set, shift directory, number of resource group bindings.

[0068] In an exemplary embodiment, the base station configures M CORESETs or SSs for the UE and indicates to the UE that the DCIs on N CORESETs or SSs among the M CORESETs or SSs are repeated, where M and N are positive integers and M > N > 1, such as M = 4 and N = 2.

[0069] In this embodiment, reference information for the repeated DCI can be configured in any one or a combination of the following ways.

[0070] The first way is that the base station only configures reference information for the SSs where 2 repeated DCIs are located, and does not configure reference information for the SSs where the other 2 non-repeated DCIs are located.

[0071] If the DCIs on the first SS and the second SS are repeated, and the ID corresponding to the first SS is SSID1 and the ID corresponding to the second SS is SSID2, then an SSREF field is added to the first SS, and the content in the SSREF field is SSID2, and an SSREF field is added to the second SS, and the content in the SSREF field is SSID1.

[0072] The second way is that the base station only configures reference information for the CORESETs where 2 repeated DCIs are located, and does not configure reference information for the CORESETs where the other 2 non-repeated DCIs are located.

[0073] If the DCIs on the first CORESET and the second CORESET are repeated, and the ID corresponding to the first CORESET is CORESETID1 and the ID corresponding to the second CORESET is CORESETID2, then a CORESETREF field is added to the first CORESET, and the content in the CORESETREF field is CORESETID2, and a CORESETREF field is added to the second CORESET, and the content in the CORESETREF field is CORESETID1.

[0074] In the third way, the base station configures duplicate signaling rules.

[0075] Configuring duplicate signaling rules includes at least one of the following: for two duplicate DCIs, configuring the same one or more first information elements on the SS; for two non-duplicate DCIs, configuring different one or more first information elements on the SS. For two duplicate DCIs, configuring the same one or more second information elements on the CORESET; for two non-duplicate DCIs, configuring different one or more second information elements on the CORESET.

[0076] Among them, the first information element can be at least one of the following: the first duration, the monitoring time slot period, the monitoring time slot period offset, the number of candidate PDCCHs, the DCI format, the symbol position within the monitoring time slot, etc. Among them, the second information element can be at least one of the following: the second duration, the control channel element to resource element group mapping type, the frequency domain resource, the interleaving size, the scrambling ID of the PDCCH DMRS, the precoding granularity, the transmission control information set, the shift directory, or the number of resource group bindings.

[0077] For example: the same first duration, the same monitoring time slot period, the same monitoring time slot period offset, the same number of candidate PDCCHs, the same DCI format, and the same symbol position within the monitoring time slot are configured on the search space SS.

[0078] For example: the same configured second duration, the same control channel element to resource element group mapping type, the same frequency domain resource, the same interleaving size, the same scrambling ID of the PDCCH DMRS, the same precoding granularity, the same transmission control information set, the same shift directory, or the same number of resource group bindings are configured on the control channel resource set CORESET.

[0079] The UE determines the time-frequency resource position for blindly decoding the DCI, the number of DCIs that need to be blindly decoded, and the time-frequency resource position of the duplicate DCI according to the information of M CORESETs or SSs configured by the base station and the rule indicating the duplicate DCI.

[0080] In an exemplary embodiment, determining N duplicate DCIs in the DCI set includes at least one of the following ways: determining the N DCIs in the DCI set that satisfy the high-layer duplicate signaling rules as duplicate DCIs; determining the N DCIs in the DCI set that have the search space reference SSREF field on the search space SS as duplicate DCIs; determining the N DCIs in the DCI set that have the channel control channel resource set reference CORESETREF field on the control channel resource set CORESET as duplicate DCIs; where the content of all fields included in the N DCIs is the same.

[0081] In an exemplary embodiment, determining N duplicate DCIs in a DCI set may be that the UE detects that there is an SSREF field in both the first SS and the second SS, the contents in the SSREF field are SSID2 and SSID1 respectively, SSID1 corresponds to the first SS, and SSID2 corresponds to the second SS, then it is determined that the DCIs on the first SS and the second SS are duplicate DCIs.

[0082] In an exemplary embodiment, determining N duplicate DCIs in a DCI set may also be that the UE detects that there is a CORESETREF field in both the first CORESET and the second CORESET, the contents in the CORESETREF field are CORESETID2 and CORESETID1 respectively, CORESETID1 corresponds to the first CORESET, and CORESETID2 corresponds to the second CORESET, then it is determined that the DCIs on the first CORESET and the second CORESET are duplicate DCIs.

[0083] In an exemplary embodiment, determining N duplicate DCIs in a DCI set may also be that at least one or more identical first information elements are detected on the SS, then it is determined that the DCI on the SS is a duplicate DCI. The first information element may be at least one of the following: the first duration, the monitoring time slot period, the monitoring time slot period offset, the number of candidate PDCCHs, the DCI format, the symbol position within the monitoring time slot, etc.

[0084] In an exemplary embodiment, determining N duplicate DCIs in a DCI set may also be that at least one or more identical second information elements are detected on the CORESET, then it is determined that the DCI on the CORESET is a duplicate DCI. The second information element may be at least one of the following: the second duration, the control channel element to resource element group mapping type, the frequency domain resource, the interleaving size, the scrambling ID of the PDCCH DMRS, the precoding granularity, the transmission control information set, the shift directory, the number of resource group bindings, etc.

[0085] S120. Determine the relevant information of the DCIs in the DCI set according to the duplicate DCIs.

[0086] In an exemplary embodiment, the determining the relevant information of the DCIs in the DCI set according to the duplicate DCIs includes one of the following methods:

[0087] Determine the value of the downlink allocation indicator DAI of the DCI set according to the duplicate DCIs;

[0088] Determine the transmission time slot of the resources scheduled by the duplicate DCIs according to the duplicate DCIs;

[0089] Determine the redundancy version RV of the repeated DCI according to the repeated DCI;

[0090] Determine the value of the DCI set DAI and the transmission time slot of the resources scheduled by the repeated DCI according to the repeated DCI;

[0091] Determine the value of the downlink allocation indication DAI of the DCI set and the redundancy version RV of the repeated DCI according to the repeated DCI.

[0092] Further, the DCI set includes M DCIs, where the M DCIs include N repeated DCIs and M - N non-repeated DCIs; the first DCI subset contains N repeated DCIs, where M is a positive integer and M > N.

[0093] In an exemplary embodiment, determine the value of the downlink allocation indication DAI of the DCI set according to the repeated DCI.

[0094] In an exemplary embodiment, the determining the value of the downlink allocation indication DAI in the DCI set according to the repeated DCI includes: determining the value of the DCI set DAI according to the detection results of the N repeated DCIs in the first DCI subset, where the DAI values of the repeated DCIs in the first DCI subset are the same.

[0095] In this embodiment, the UE can determine which positions of the DCI are repeated according to the reference information of the base station. Figure 3 It is a schematic diagram of the DAI value when all the repeated DCIs provided in this application are detected. As Figure 3 shown, the UE blindly decodes the DCI at the positions of (occasion 0, CC0), (occasion 0, CC1), (occasion 0, CC2), (occasion 1, CC0), and (occasion 1, CC1) in sequence, and knows that the DCIs at (occasion 0, CC0) and (occasion 1, CC0) are repeated, that is, the DCI with 1 at the position of the virtual frame in the figure is repeated with the DCI with 1 at the position of the real frame. However, when the UE blindly decodes the DCI, it cannot guarantee correct demodulation of all DCIs, and it is necessary to consider the detection situation of the repeated DCIs and how to solve the problem of DAI misalignment.

[0096] Figure 4 It is a schematic diagram of the DAI calculation provided in this application. As Figure 4 shown, the calculation of the DAI value is to accumulate in the order of time domain first and then frequency domain, and then add 1 modulo 4 to the result.

[0097] In an exemplary embodiment, if none of the duplicate DCIs in the first DCI subset is detected, the value of the DCI set DAI is determined according to the order in which the DCIs are actually detected. Figure 5 is a schematic diagram of the DAI value when none of the duplicate DCIs of this application is detected. As Figure 5 shown, none of the duplicate DCIs is detected, that is Figure 5 the 1s at the positions of the solid frame and the dashed frame in are not detected, and the UE will calculate the DAI value according to the order in which the DCIs are actually detected, rather than reserving the DAI value in the DCI. That is, the final DAI value is 123 instead of 234.

[0098] In an exemplary embodiment, if at least one duplicate DCI in the first DCI subset is detected, the DCI with the smallest time-domain opportunity index and carrier unit index in the first DCI subset is used as the target DCI, the DAI in the first DCI subset is placed at the target DCI position, and the DAI value of the DCI set is determined according to the DAI of the target DCI and the DAIs of the non-duplicate DCIs in the DCI set, where the position of the DAI is jointly determined by the time-domain opportunity index and the carrier unit index.

[0099] Among them, the DAI values at the positions of the non-target DCIs in the first DCI subset are ignored, the relative order between the DAIs of the non-duplicate DCIs in the DCI set remains unchanged, and the relative order between the DAIs of the non-duplicate DCIs in the DCI set and the DAI of the target DCI remains unchanged, where the DAI values of the non-duplicate DCIs in the DCI set are determined according to the content of the DAI field in the detected DCI.

[0100] Figure 3 is a schematic diagram of the DAI value when all the duplicate DCIs of this application are detected. As Figure 3 shown, both of the two DCIs are detected, and the 1s at the positions of the solid frame and the dashed frame are both detected. The UE determines that the DCIs at the positions of the 1s in the solid frame and the dashed frame are duplicate according to the detection result and the base station configuration. After blind decoding, the DAI value is 12314. At this time, the UE already knows that the first solid-frame 1 and the second dashed-frame 1 are duplicate, and the target DCI among the duplicate DCIs is located at the position of the first solid-frame 1. The final DAI value is 1234.

[0101] Figure 6 is a schematic diagram of the DAI value when only the front duplicate DCI is detected. Only the frontmost duplicate DCI is detected, that is Figure 6 the solid-frame 1 in is detected, and the dashed-frame 1 is not detected. The target DCI among the duplicate DCIs is located at the position of the first solid-frame 1. After the UE blindly decodes, the DAI value is 1234, and the DAI value is normal.

[0102] Figure 7It is a schematic diagram of the DAI value when only the last repeated DCI of this application is detected. Only the last repeated DCI is detected, that is Figure 7 the solid frame 1 in it is not detected, and the dashed frame 1 is detected. After the UE blindly decodes, the DAI value is 2341. The UE knows that the DCI at the position of the solid frame 1 and the DCI of the dashed frame 1 are repeated. Although the DCI at the position of the solid frame 1 is not detected, the target DCI in the repeated DCIs is located at the position of the first solid frame 1, and the final DAI value is 1234.

[0103] Figure 8 It is a schematic diagram of the final DCI sequence when at least one repeated DCI of this application is detected. For the above three cases where at least one repeated DCI is detected, the final DAI value of the repeated DCI needs to be placed at the position of the DCI with the smallest time domain opportunity index and carrier unit index in the repeated DCI, corresponding to Figure 8 the position of the solid frame 1 in it, and the final DCI value obtained by OR operation is 1234.

[0104] In an exemplary embodiment, the transmission time slot for the resources scheduled by the repeated DCI is determined according to the repeated DCI.

[0105] In an exemplary embodiment, determining N repeated DCIs in the DCI set includes: determining N DCIs that meet the high-layer repeated signaling rules in the DCI set as repeated DCIs; determining N DCIs that have a search space reference SSREF field on the search space SS in the DCI set as repeated DCIs; determining N DCIs that have a channel control channel resource set reference CORESETREF field on the control channel resource set CORESET in the DCI set as repeated DCIs; where the content of all fields included in the N DCIs is the same.

[0106] In this embodiment, determining N repeated DCIs in the DCI set is basically the same as that provided in the above embodiment. The specific implementation manner can refer to the description in the above embodiment and will not be repeated in this embodiment.

[0107] In an exemplary embodiment, the resource type and the number of resources scheduled by the repeated DCI are determined, where the resource type includes at least one of the following: physical downlink shared channel PDSCH, physical uplink shared channel PUSCH, aperiodic sounding reference signal AP SRS.

[0108] Among them, the N repeated DCIs are transmitted in N different transmission time slots, and the repeated DCI schedules the same resource.

[0109] In an exemplary embodiment, the method further includes: receiving configured first resource information, where the first resource information includes: the type and number of repeated DCI scheduling resources, and the resource reference DCI for repeated DCI scheduling. The resource type includes at least one of the following: physical downlink shared channel PDSCH, physical uplink shared channel PUSCH, and aperiodic sounding reference signal AP SRS. The first resource information is configured by the base station.

[0110] In an exemplary embodiment, determining the resource transmission time slot for repeated DCI scheduling includes: determining the resource transmission time slot for repeated DCI scheduling according to the reference DCI of the N repeated DCIs. The reference DCI includes at least one of the following: the DCI with the smallest transmission time slot among the N repeated DCIs; the DCI with the largest transmission time slot among the N repeated DCIs; the DCI with the smallest control channel resource set identifier corresponding to the N repeated DCIs; the DCI with the largest control channel resource set identifier corresponding to the N repeated DCIs; the DCI with the smallest search space identifier corresponding to the N repeated DCIs; the DCI with the largest search space identifier corresponding to the N repeated DCIs.

[0111] In an exemplary embodiment, the base station configures M CORESETs or SSs for the UE and indicates to the UE that the DCIs on the N CORESETs or SSs are repeated, where M and N are positive integers and M > N > 1, for example, M = 4 and N = 2.

[0112] The base station configures that the repeated DCI can only schedule one PDSCH on different time slots (slots).

[0113] The base station configures that the repeated DCI can only schedule one PDSCH on different time slots (slots), and the position of the PDSCH is determined by the DCI with the smallest transmission time slot.

[0114] The UE determines the time-frequency resource position for blindly decoding the DCI, the number of DCIs that need to be blindly decoded, and the time-frequency resource position of the repeated DCI according to the information of the M CORESETs or SSs configured by the base station and the rule indicating the repeated DCI.

[0115] The UE determines the type and number of the finally scheduled resources according to the number of PDSCH resources that the repeated DCI configured by the base station can schedule and the detection situation of the blindly decoded repeated DCI.

[0116] If the UE determines according to the finally blindly decoded result and the base station configuration that the two repeated DCIs are on different time slots (slots) and schedule the same PDSCH, then there is a time slot offset problem between the repeated DCI with a later transmission time slot and the scheduled PDSCH.

[0117] Figure 9It is a schematic structural diagram of a repeated DCI in the present application scheduling a PDSCH on different time slots. As Figure 9 shown, DCI0 and DCI1 are repeated and both schedule PDSCH1. DCI0, DCI1, and PDSCH are located on slot p1, slot p2, and slot p1 + q1 respectively, where p2 > p1 > 0 and q1 > (p2 - p1).

[0118] If the transmission time slot of the PDSCH scheduled by the DCI is determined according to the existing protocol, DCI0 and DCI1 will schedule different PDSCHs. To ensure that the same PDSCH is scheduled, when calculating the transmission time slot of the PDSCH scheduled by DCI1, DCI0 should be referred to.

[0119] When the resource scheduled by the repeated DCI is the PDSCH, the transmission time slot Td of the PDSCH is determined by referring to the transmission time slot n of the DCI, the carrier spacing parameter μ PDSCH of the PDSCH, the carrier spacing parameter μ PDCCH of the physical downlink control channel corresponding to the DCI, and K0. Here, K0 is the transmission time slot offset between the reference DCI and the PDSCH, and K0 can take 0 or 1.

[0120] Furthermore, when N repeated DCIs schedule a PDSCH, the reference time slot of the PDSCH is the time slot where the DCI with the smallest time slot among the repeated DCIs is located. The transmission time slot of the PDSCH is:

[0121]

[0122] where TD is the transmission time slot of the PDSCH scheduled by the repeated DCI, n1 is a positive integer, μ PDSCH is the PDSCH carrier spacing configuration parameter, μ PDCCH is the physical layer downlink control channel PDCCH carrier spacing configuration parameter, K0 is the time slot offset between the repeated DCI and the PDSCH it schedules, K0 is determined by the numerology information of the system parameter set of the PDSCH, K0 is 0 or 1, and n1 is the time slot where the DCI with the smallest time slot in the first DCI subset is located.

[0123] In an exemplary embodiment, the base station configures M CORESETs or SSs for the UE and indicates to the UE that the DCIs on the N CORESETs or SSs are repeated, where M and N are positive integers and M > N > 1, such as M = 4 and N = 2.

[0124] The base station configures that the repeated DCI can only schedule one PDSCH on different time slots slot.

[0125] The base station configures duplicate DCIs in different slots and schedules a PDSCH. The position of the PDSCH is determined by the DCI with the smallest transmission time slot.

[0126] When the base station configures duplicate DCIs in different slots and schedules a PDSCH, and determines spatial correlation parameters, the time interval between the DCI and the PDSCH is the time interval between the DCI with the largest transmission time slot and the scheduled PDSCH.

[0127] The UE determines the time-frequency resource position for blindly decoding the DCI, the number of DCIs that need to be blindly decoded, and the time-frequency resource position of the duplicate DCI according to the information of M CORESETs or SSs configured by the base station and the rule indicating the duplicate DCI.

[0128] The UE determines the type and number of finally scheduled resources according to the number of PDSCH resources that the duplicate DCI configured by the base station can schedule and the detection situation of the duplicate DCI after blind decoding.

[0129] The UE determines according to the result of the final blind decoding based on the base station configuration that two duplicate DCIs are located in different slots and schedule the same PDSCH. The position of the PDSCH is determined by the duplicate DCI with the smallest transmission time slot. When determining the spatial correlation parameters by the earliest duplicate DCI, the time interval between the duplicate DCI and the PDSCH is the time interval between the DCI with the largest transmission time slot and the scheduled PDSCH.

[0130] As Figure 9 shown, DCI0 and DCI1 are duplicates and both schedule PDSCH0. DCI0, DCI1, and PDSCH0 are located in slot p1, slot p2, and slot p1+q1 respectively, where p2>p1>0 and q1>(p2-p1).

[0131] If the time interval between the DCI and the scheduled PDSCH is determined according to the existing protocol, obviously the time interval between DCI0 and the scheduled PDSCH is greater than the time interval between DCI1 and the scheduled PDSCH. To ensure the default receiving beam with the same criterion, when determining the spatial correlation parameters, the time interval between DCI0 and the scheduled PDSCH is calculated with reference to the time interval between DCI1 and the scheduled PDSCH.

[0132] The time interval between the duplicate DCI and the scheduled PDSCH is determined according to the difference between the transmission time slot of the PDSCH and the transmission time slot n2 of the second reference DCI; the spatial correlation parameters of the PDSCH are determined according to the time interval. Wherein, the second reference DCI is any DCI in the reference DCIs other than the first reference DCI.

[0133] Further, the time interval between the repeated DCI and the scheduled PDSCH is:

[0134]

[0135] where Td is the time interval between the repeated DCI and the PDSCH, n1 is a positive integer, n1 is the time slot where the repeated DCI with the smallest time slot is located, n2 is the time slot where the repeated DCI with the largest time slot is located, μ PDSCH is the PDSCH carrier spacing configuration parameter, μ PDCCH is the PDCCH carrier spacing configuration parameter, K 0 is the time slot offset between the repeated DCI and the PDSCH it schedules, K 0 is determined by the numerology information of the system parameter set of the PDSCH, K 0 is 0 or 1, and both n1 and n2 are positive integers.

[0136] In an exemplary embodiment, the base station configures M CORESETs or SSs for the UE and indicates to the UE that the DCIs on N CORESETs or SSs are repeated, where M and N are positive integers and M > N > 1, such as M = 4 and N = 2.

[0137] The base station configures that the repeated DCI can only schedule one PUSCH on different slots.

[0138] The base station configures the repeated DCI to schedule one PUSCH on different slots, and the PUSCH position is determined by the DCI with the smallest transmission time slot.

[0139] The UE determines the time-frequency resource position for blindly decoding the DCI, the number of DCIs that need to be blindly decoded, and the time-frequency resource position of the repeated DCI according to the information of the M CORESETs or SSs configured by the base station for the UE and the rule indicating the repeated DCI.

[0140] The UE determines the type and number of the finally scheduled resources according to the number of PUSCH resources that the repeated DCI configured by the base station can schedule and the detection situation of the repeated DCI after blind decoding.

[0141] If the UE determines according to the final blind decoding result of the base station configuration that two repeated DCIs are located on different slots and schedule the same PUSCH, and the PUSCH position is determined by the DCI with the smallest transmission time slot, then there is a time slot offset problem between the repeated DCI with a later transmission time slot and the scheduled PUSCH.

[0142] Figure 10 is the structural schematic diagram of the repeated DCI provided by this application for scheduling one PUSCH on different time slots, such as Figure 10As shown, DCI0 and DCI1 are duplicates and both schedule PUSCH0. DCI0, DCI1, and PUSCH0 are located in slot p1, slot p2, and slot p1+q2 respectively, where p2>p1>0 and q2>(p2-p1).

[0143] If the transmission time slots of PUCCH scheduled by DCI are determined according to the existing protocol, DCI0 and DCI1 will schedule different PUSCHs. To ensure scheduling the same PUSCH, when calculating the transmission time slot of PDSCH scheduled by DCI1, DCI0 should be referenced.

[0144] The resources scheduled by the duplicate DCI are the physical layer uplink shared channel PUSCH. The transmission time slot TU of the PUSCH is determined by referring to the transmission time slot n of the DCI, the carrier spacing parameter μ PUSCH of the physical downlink control channel corresponding to the DCI PDCCH and K1, where K1 is the transmission time slot offset between the reference DCI and the PUSCH.

[0145] Furthermore, N duplicate DCIs schedule one PUSCH. The reference time slot of the PUSCH is the time slot where the DCI with the smallest time slot among the duplicate DCIs is located. The PUSCH transmission time slot is:

[0146]

[0147] where TU is the PUSCH transmission time slot scheduled by the duplicate DCI, n1 is the time slot where the DCI with the smallest time slot among the duplicate DCIs is located, μ PUSCH is the PUSCH carrier spacing configuration parameter, μ PDCCH is the PDCCH carrier spacing configuration parameter, K 1 is the time slot offset between the duplicate DCI and the PUSCH it schedules. K1 is determined by the numerology information of the system parameter set of the PDSCH. K1 is any positive integer from 1 to 6.

[0148] In an exemplary embodiment, the base station configures M CORESETs or SSs for the UE and indicates to the UE that the DCIs on N CORESETs or SSs are duplicates, where M and N are positive integers and M>N>1, such as M = 4 and N = 2. The situation of detecting at least one duplicate DCI is considered.

[0149] The base station configures that the duplicate DCI can only schedule one AP SRS on different slots.

[0150] The base station configures the duplicate DCI to schedule one AP SRS on different slots, and the position of the APSRS is determined by the DCI with the smallest transmission time slot.

[0151] The UE determines the time-frequency resource location for blindly decoding DCI, the number of DCI to be blindly decoded, and the time-frequency resource location of the repeated DCI according to the information of M CORESETs or SSs configured by the base station and the rule indicating the repeated DCI.

[0152] The UE determines the type and number of resources finally scheduled according to the number of AP SRS resources that the repeated DCI configured by the base station can schedule and the detection situation of the repeated DCI after blind decoding.

[0153] Based on the result of the final blind decoding according to the base station configuration, the UE determines that two repeated DCIs are in different slots and schedule the same AP SRS. If the DCI with the smallest transmission time slot determines the SRS position, there is a time slot offset problem between the repeated DCI with a later transmission time slot and the scheduled AP SRS.

[0154] Figure 11 The structure diagram of the repeated DCI provided by this application for scheduling an AP SRS in different time slots is as Figure 11 shown. DCI0 and DCI1 are repeated and both schedule SRS0. DCI0, DCI1, and SRS0 are located in slot p1, slot p2, and slot p1 + q3 respectively, where p2 > p1 > 0 and q3 > (p2 - p1).

[0155] If the transmission time slot of the AP SRS triggered by the DCI is determined according to the existing protocol, DCI0 and DCI1 will trigger different AP SRSs. To ensure triggering the same AP SRS, when calculating the transmission time slot of the AP SRS triggered by DCI1, DCI0 should be referenced.

[0156] The resource scheduled by the repeated DCI is an AP SRS. The transmission time slot TA of the AP SRS is determined by referring to the transmission time slot n of the DCI, the carrier spacing parameter μ of the AP SRS SRS , the carrier spacing parameter μ of the physical downlink control channel corresponding to the DCI PDCCH and k. Here, k is the time slot offset between the reference DCI and the transmission time slot of the AP SRS, and k is determined by the time slot offset parameter in the SRS resource set in the high-layer signaling. k is any integer from 0 to 32.

[0157] Furthermore, when the N repeated DCIs schedule an AP SRS, the resource transmission time slot is the time slot where the DCI with the smallest time slot among the repeated DCIs is located. The transmission time slot of the AP SRS is:

[0158]

[0159] Among them, TA is the AP SRS transmission time slot for repeated DCI scheduling, n1 is the time slot where the repeated DCI with the smallest time slot is located, and μ SRS is the SRS carrier spacing configuration parameter, and μ PDCCH is the PDCCH carrier spacing configuration parameter. k is the time slot offset between the DCI and the AP SRS it schedules. k is determined by the time slot offset parameter in the SRS resource set in the high-layer signaling. k is an integer from 0 to 32.

[0160] In an exemplary embodiment, the redundant version RV of the repeated DCI is determined according to the repeated DCI.

[0161] In an exemplary embodiment, the determination of N repeated DCIs in the DCI set includes at least one of the following: determining N DCIs in the DCI set that meet the high-layer repeated signaling rules as repeated DCIs; determining N DCIs in the DCI set that have a search space reference SSREF field on the search space SS as repeated DCIs; determining N DCIs in the DCI set that have a channel control channel resource set reference CORESETREF field on the channel control channel resource set CORESET as repeated DCIs.

[0162] In this embodiment, the determination of N repeated DCIs in the DCI set is basically the same as that provided in the above embodiment. The specific implementation manner can refer to the description in the above embodiment and will not be elaborated in this embodiment.

[0163] Determine the resource type and the number of resources scheduled by the repeated DCI. Among them, the resource type includes at least one of the following: physical downlink shared channel PDSCH, physical uplink shared channel PUSCH.

[0164] Furthermore, the N repeated DCIs are transmitted in N different transmission time slots, and the repeated DCI schedules multiple said resources.

[0165] In an exemplary embodiment, the determination of the redundant version RV of the repeated DCI includes: determining the redundant version RV of the repeated DCI according to the configured redundant version RV remapping rule and the detection result of the repeated DCI.

[0166] In an exemplary embodiment, the method further includes: receiving pre-configured second resource information, where the second resource information includes: the resource type and number of resources scheduled by the repeated DCI, the redundant version RV of the repeated DCI, and the resource type includes at least one of the following: physical downlink shared channel PDSCH, physical uplink shared channel PUSCH.

[0167] In an exemplary embodiment, when the N repeated DCIs schedule N PDSCHs, the redundancy versions RVs in the repeated DCIs are remapped according to a predetermined rule.

[0168] In an exemplary embodiment, when the N repeated DCIs schedule N PUSCHs, the redundancy versions RVs in the repeated DCIs are remapped according to a predetermined rule.

[0169] In an exemplary embodiment, the base station configures M CORESETs or SSs for the UE and indicates to the UE that the DCIs on the N CORESETs or SSs are repeated, where M and N are positive integers and M > N > 1, for example, M = 4 and N = 2.

[0170] The base station configures the repeated DCIs to be able to schedule multiple PDSCHs on different slots.

[0171] The base station configures the repeated DCIs to schedule multiple PDSCHs on different slots, and the RV remapping rule of the repeated DCIs.

[0172] The UE determines the time-frequency resource position for blindly decoding the DCI, the number of DCIs that need to be blindly decoded, and the time-frequency resource position of the repeated DCIs according to the information of the M CORESETs or SSs configured by the base station for the UE and the rule indicating the repeated DCI.

[0173] The UE determines the type and number of the finally scheduled resources according to the number of PDSCH resources that the repeated DCI configured by the base station can schedule and the detection situation of the repeated DCI after blind decoding.

[0174] The UE determines the final RV of the repeated DCI according to the RV remapping rule of the repeated DCI configured by the base station and the detection situation of the repeated DCI after blind decoding.

[0175] The UE determines that the 2 repeated DCIs are located on different slots according to the final blind decoding result based on the base station configuration, and schedule 2 different PDSCHs, and determine the RVs in the repeated DCIs according to the RV remapping rule configured by the base station.

[0176] Figure 12 FIG. is a schematic structural diagram of the repeated DCI provided by the present application for scheduling multiple PDSCHs on different time slots, as Figure 12 shown, DCI0, DCI1, PDSCH0, and PDSCH1 are respectively located on slot p1, slot p2, slot p1 + td1, and slot p2 + td2, where p2 > p1 > 0 and (p2 + td2) > (p1 + td1), and DCI0 and DCI1 respectively schedule PDSCH0 and PDSCH1.

[0177] Although DCI1 and DCI0 carry the same content, they are decoded in different slots. Although they are the same RV, the UE can have different understandings and can remap the RV using different rules. For example, the base station configures the cumulative count (starting from 1) of the decoding order of the repeated DCIs modulo 4 as the directory index for RV remapping, and maps them to the corresponding elements in the RV remapping sequence in order of the directory index. The RV remapping sequence can be {0, 3, 2, 1} or {0, 2, 3, 1} or {0, 1, 2, 3}. For two repeated DCIs in this embodiment, if mapped according to {0, 3, 2, 1}, the RVs in DCI0 and DCI1 are 0 and 3 respectively; if mapped according to {0, 2, 3, 1}, the RVs in DCI0 and DCI1 are 0 and 2 respectively; if mapped according to {0, 1, 2, 3}, the RVs in DCI0 and DCI1 are 0 and 1 respectively.

[0178] In an exemplary embodiment, the base station configures M CORESETs or SSs for the UE and indicates to the UE that the DCIs on N CORESETs or SSs are repeated, where M and N are positive integers and M > N > 1, such as M = 4 and N = 2.

[0179] The base station configures repeated DCIs to be able to schedule multiple PUSCHs on different slots.

[0180] The base station configures repeated DCIs to schedule multiple PUSCHs on different slots, and the RV remapping rule for the repeated DCIs.

[0181] The UE determines the time-frequency resource positions for blind decoding of DCIs, the number of DCIs that need to be blindly decoded, and the time-frequency resource positions of the repeated DCIs according to the information of M CORESETs or SSs configured by the base station for the UE and the rule indicating the repeated DCIs.

[0182] The UE determines the type and number of the finally scheduled resources according to the number of PDSCH / PUSCH / AP SRS resources that the repeated DCIs configured by the base station can schedule and the detection situation of the repeated DCIs after blind decoding.

[0183] The UE determines the final RV of the repeated DCIs according to the RV remapping rule of the repeated DCIs configured by the base station and the detection situation of the repeated DCIs after blind decoding.

[0184] The UE determines that two repeated DCIs are located on different slots and schedule two different PUSCHs according to the result of the final blind decoding based on the base station configuration, and determines the RV in the repeated DCIs according to the RV remapping rule configured by the base station.

[0185] Figure 13 This is a schematic structural diagram of the repeated DCIs provided in this application for scheduling multiple PUSCHs on different time slots, such asFigure 13 As shown, DCI0, DCI1, PUSCH0, and PUSCH1 are respectively located on slot p1, slot p2, slot p1+tu1, and slot p2+tu2, where p2>p1>0 and (p2+tu2)>(p1+tu1). DCI0 and DCI1 respectively schedule PUSCH0 and PUSCH1.

[0186] Although DCI1 and DCI0 carry the same content, they are decoded on different slots. Although they are the same RV, the UE can have different understandings and different rules can be used to remap the RV. For example, the base station configures the cumulative count (starting from 1) of the decoding order of the repeated DCIs modulo 4 as the directory index for RV remapping, and maps them to the corresponding elements in the RV remapping sequence in order of the directory index. The RV remapping sequence can be {0, 3, 2, 1} or {0, 2, 3, 1} or {0, 1, 2, 3}. For the two repeated DCIs in this embodiment, if mapped according to {0, 3, 2, 1}, the RVs in DCI0 and DCI1 are 0 and 3 respectively; if mapped according to {0, 2, 3, 1}, the RVs in DCI0 and DCI1 are 0 and 2 respectively; if mapped according to {0, 1, 2, 3}, the RVs in DCI0 and DCI1 are 0 and 1 respectively.

[0187] In an exemplary embodiment, Figure 14 is a flowchart of an information enhancement method of the present application. This method can be applied to the case of PDCCH repeated transmission in a Multi-TRP / Pannel scenario. This method can be executed by the information enhancement device provided by the present application, and the information enhancement device can be implemented by software and / or hardware and integrated on the base station.

[0188] As Figure 14 shown, the information enhancement method provided by the embodiment of the present application mainly includes steps S1410 and S1420.

[0189] S1410. Configure the association relationship, first resource information, and second resource information of N repeated DCIs.

[0190] Among them, the association relationship is used to determine the repeated DCI. The DCI set includes M DCIs, where M DCIs include N repeated DCIs and M-N non-repeated DCIs; the DCI set includes a first DCI subset and a second DCI subset. The first DCI subset contains N repeated DCIs, and the second DCI subset includes M-N non-repeated DCIs, where M and N are both positive integers and M>N>1.

[0191] In an exemplary embodiment, the configuration of the association relationship of N repeated DCIs includes at least one of the following:

[0192] Add an SSREF field to each repeated DCI on the search space SS, where the content in the SSREF field is not the search space identifier SSID of the current DCI.

[0193] Add a CORESETREF field to each repeated DCI on the control channel resource set CORESET, where the content in the CORESETREF field is not the control channel resource set identifier CORESETID of the current DCI.

[0194] Define a high-layer repeated signaling rule, where the repeated signaling rule includes at least one of the following: includes at least one of the following: the same first information element is configured on the SS, where the first information element includes at least one of the following: the first duration, the monitoring time slot period, the monitoring time slot period offset, the number of candidate PDCCHs, the DCI format, the symbol position within the monitoring time slot; the same second information element is configured on the CORESET, where the second information element includes at least one of the following: the second duration, the control channel element to resource element group mapping type, the frequency domain resource, the interleaving size, the scrambling ID of the PDCCH DMRS, the precoding granularity, the transmission control information set, the shift directory, the number of resource group bindings.

[0195] Furthermore, in this embodiment, the association relationship of the repeated DCI can be configured in any one or a combination of the following ways.

[0196] The first way is to add an SSREF field to each repeated DCI on the search space SS. The base station only configures the association relationship for the SS where 2 repeated DCIs are located, and does not configure the association relationship for the SS where the other 2 non-repeated DCIs are located.

[0197] If the DCIs on the first SS and the second SS are repeated, and the ID corresponding to the first SS is SSID1 and the ID corresponding to the first SS is SSID2, then add an SSREF field to the first SS, and the content in the SSREF field is SSID2, and add an SSREF field to the second SS, and the content in the SSREF field is SSID1.

[0198] The second way is to add a CORESETREF field to each repeated DCI on the control channel resource set CORESET, where the content in the CORESETREF field is not the CORESETID of the current DCI. The base station only configures the association relationship for the CORESET where 2 repeated DCIs are located, and does not configure the association relationship for the CORESET where the other 2 non-repeated DCIs are located.

[0199] If the DCIs on the first CORESET and the second CORESET are duplicates, and the ID corresponding to the first CORESET is CORESETID1, and the ID corresponding to the second CORESET is CORESETID2, then add a CORESETREF field to the first CORESET, and the content in the CORESETREF field is CORESETID2. Add a CORESETREF field to the second CORESET, and the content in the CORESETREF field is CORESETID1.

[0200] In the third method, configure the high-layer duplicate signaling rules.

[0201] Configuring the duplicate signaling rules includes at least one of the following: for two duplicate DCIs, configure the same one or more first information elements on the SS; for two non-duplicate DCIs, configure different one or more first information elements on the SS. For two duplicate DCIs, configure the same one or more second information elements on the CORESET; for two non-duplicate DCIs, configure different one or more second information elements on the CORESET.

[0202] Among them, the first information element can be at least one of the following: the first duration, the monitoring time slot period, the monitoring time slot period offset, the number of candidate PDCCHs, the DCI format, the symbol position within the monitoring time slot, etc. Among them, the second information element can be at least one of the following: the second duration, the control channel element to resource element group mapping type, the frequency domain resource, the interleaving size, the scrambling ID of the PDCCH DMRS, the precoding granularity, the transmission control information set, the shift directory, or the number of resource group bindings.

[0203] For example: the same first duration, the same monitoring time slot period, the same monitoring time slot period offset, the same number of candidate PDCCHs, the same DCI format, and the same symbol position within the monitoring time slot are configured on the search space SS.

[0204] For example: the same configured second duration, the same control channel element to resource element group mapping type, the same frequency domain resource, the same interleaving size, the same scrambling ID of the PDCCH DMRS, the same precoding granularity, the same transmission control information set, the same shift directory, or the same number of resource group bindings are configured on the control channel resource set CORESET.

[0205] In an exemplary embodiment, the first resource information includes the type and number of repeated DCI scheduling resources, and the resource reference DCI for the repeated DCI scheduling. The resource type includes at least one of the following: Physical Downlink Shared Channel (PDSCH), Physical Uplink Shared Channel (PUSCH), Aperiodic Probing Reference Signal (AP SRS).

[0206] Configuring the first resource information includes, but is not limited to, at least one of the following:
