This is not limited in this embodiment of the present invention.

As an example, this embodiment of the present invention contains one UE and at least two TRPs (or one TRP contains two panels). The repeated PDCCHs or repeated PDSCHs come from two different TRPs and may be on different CCs or BWPs or on the same CC or BWP.

In the embodiment of FIG. 1 is a flow diagram of a method for optimizing information according to the present invention. The method can be applied to cases of repetitive PDCCH transmission in multi-TRP/panel scenarios. This method can be executed by the information optimization apparatus provided according to the present invention. The information optimization apparatus may be implemented in software and/or hardware and integrated into the user equipment (UE).

As shown in FIG. 1, the information optimization method provided according to this embodiment of the present invention mainly includes S110 and S120.

At S110, a first DCI subset in a downlink control information (DCI) set and a second DCI subset in the DCI set are determined, wherein the first DCI subset contains N repeating DCI fragments, the second DCI subset contains M-N non-repeating DCI fragments, N is an integer greater than 1 and M is an integer greater than N.

DCI refers to information carried on the PDDCH. Different types of DCIs can contain different areas and different content in the areas.

For example, a downlink assignment index (DAI) is used to indicate that multiple subframes contain a downlink transmission within the hybrid automatic repeat request (HARQ) feedback time window to prevent possible false acknowledgment of sending back information (ACK). ) by the UE if the DCI part is lost. In NR protocols, the DAI area exists only in DCI formats 0_1 and 1_1.

For example, redundancy version (RV) refers to the start position of the data taken from the buffer. Different RV version data can be progressively combined to improve decoding accuracy. In NR protocols, the RV area exists only in DCI formats 0_1, 0_0, 1_0, and 1_1.

As another example, 4 bits in the Time Domain Resource Assignment Region (TDRA) in DCI format 0_0 are used to index the coordinated PUSCH interval offset K2 with respect to DCI, the symbol start position S within the coordinated PUSCH interval with respect to DCI, and the symbol length L within the coordinated PUSCH interval. PUSCH regarding DCI; and 4 bits in the TDRA region in DCI format 1_0 are used to index the coordinated PDSCH interval relative to DCI offset K0, symbol start position S within the coordinated PDSCH interval relative to DCI, and symbol length L within the coordinated PDSCH interval relative to DCI.

The PDCCH may send downlink coordination information to the UE, instructing the UE to receive the PDSCH. The PDCCH may also send uplink coordination information to the UE by instructing the UE to send a Physical Uplink Shared Channel (PUSCH). The PDCCH may also send physical uplink control channel (PUCCH), PUSCH, and sounding reference signal (SRS) power control commands. The PDCCH may also be in the notified UE slot format.

A control resource set (CORESET) consists of one or more control channel elements (CCEs) and indicates that the base station can send the position of the PDCCH time-frequency resource. However, the UE does not know which DCI shape the PDCCH is carrying, or which candidate CCE this DCI shape is being transmitted to, so the UE must blindly demodulate all possible DCI shapes on multiple CCEs of different aggregation levels. To reduce the number of blind demodulations, the concept of a search space (SS) is introduced. The SS consists of CCE sets of provided aggregation levels. The base station may configure one or more SSs for the UE. The time domain event is determined by the monitoring period in the SS and the offset in the SS, and indicates that the base station can send the position of the PDCCH time domain. A component carrier (CC) represents a subcarrier and indicates the position of the frequency domain.

The UE knows its SS according to the base station configuration information. First, the UE tries to use the appropriate Radio Network Temporary Identifier (RNTI), candidate DCI format, and candidate aggregation level to perform cyclic redundancy check (CRC) on the CCE within its SS. If the check is successful, the UE knows that it needs the information, thereby demodulating the content in DCI.

The UE blindly detects the DCI in the corresponding search space (SS) according to the sequence of the first time domain and then the frequency domain, and obtains a downlink assignment index (DAI). The content of the repeated DCI has the same DAI value, so the DAI value violates the established rules after blind demodulation, and the UE may receive an error believing that an incorrect detection has occurred. That is, when the UE blindly demodulates the DCI, it cannot be guaranteed that the entire DCI will be correctly demodulated, and it is necessary to consider a duplicate DCI detection condition and how to solve the DAI mismatch problem.

The DCI set contains M DCI fragments. The M DCI fragments contain N repeat DCI fragments and M-N non-repeated DCI fragments. The first DCI subset contains N repeat DCI fragments. M is an integer greater than N. In an illustrative example, the method further includes receiving a preconfigured correlation of N repeat DCI fragments, the correlation being used to determine the repeating DCI.

The configured correlation of N repeat DCI fragments is at least one of the following.

For each fragment of a repeated DCI, a search space pointer (SSREF) region is added to a search space (SS) where the content in the SSREF region is not the search space identifier (SSID) of the current DCI.

For each repeating DCI fragment, a control resource set pointer (CORESETREF) area is added to a control resource set (CORESET), where the content in the CORESETREF area is not the control resource set identifier (CORESETID) of the current DCI.

A repetitive high level signaling rule is predefined, wherein the repetitive signaling rule provides for at least one of the following. Each repeating DCI fragment is configured with the same first information element in the SS, the first information element containing at least one of the following: first duration, monitoring interval period, monitoring interval period offset, number of candidate PDDCHs, DCI format, or symbol position within the monitoring interval; or each repeating DCI fragment is configured with the same second information element, the second information element containing at least one of the following: second duration, control channel element to resource element group mapping type, frequency domain resource, interlace size, DMRS scrambling ID, which refers to PDCCH, degree of splitting for precoding, set of transmission control information, offset directory, or number of resource group bindings.

In an embodiment, the base station configures M CORESET or M SS for the UE and indicates to the UE that the DCI of the N CORESET in the M CORESET is repetitive, or that the DCI of the N SS in the M SS is repetitive, where M and N are positive integers. numbers, and M > N > 1, for example, M = 4, and N = 2.

In this embodiment of the present invention, any one or a combination of more of the following courses of action may be used to configure the reference information for the repeated DCI.

In the case of the first course of action: the base station configures the reference information only for the SS in which 2 repeating DCI fragments reside, and does not configure the reference information for the SS in which the other 2 non-repeating DCI fragments reside.

If the DCIs in the first SS and the DCIs in 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 area is added to the first SS, and the content in the SSREF area is SSID2; and an SSREF region is added to the second SS, and the content in the SSREF region is SSID1.

In the case of the second course of action: the base station configures the reference information only for the CORESET in which 2 repeat DCI fragments are located, and does not configure the reference information for the CORESET in which the other 2 non-repeat DCI fragments reside.

If the DCIs in the first CORESET and the DCIs in the second CORESET are repetitive, and the ID corresponding to the first CORESET is CORESETID1 and the ID corresponding to the second CORESET is CORESETID2, then a CORESETREF region is added to the first CORESET, and the content in the CORESETREF region is CORESETID2; and a CORESETREF region is added to the second CORESET, and the content in the CORESETREF region is CORESETID1.

In the case of the third course of action, the base station configures a repetitive signaling rule.

The configuration of the recurring signaling rule includes at least one of the following. The same one or more first information elements are configured for 2 repeat DCI fragments in the SS; the other one or more first information items are configured for 2 non-repeating DCI fragments in the SS; the same one or more second information items are configured for 2 repeat DCI fragments in CORESET; or other one or more second information items are configured for 2 non-repeating DCI fragments in CORESET.

The first information element may comprise at least one of a first duration, a monitoring interval period, a monitoring interval period offset, a number of candidate PDDCHs, a DCI format, or a symbol position within the monitoring interval. The second information element may comprise at least one of the following: a second duration, a type of mapping of a control channel element to a group of resource elements, a frequency domain resource, an interlace size, a DMRS scrambling ID that is related to the PDCCH, a split rate for precoding, a set of control information transfer, shift directory, or number of resource group bindings.

For example, the search space (SS) is configured with the same first duration, the same monitoring interval period, the same monitoring interval period offset, the same number of candidate PDCCHs, the same DCI format, and the same symbol position within the monitoring interval.

For example, the control resource set (CORESET) is configured with the same second duration, the same control channel element to resource element group mapping type, the same frequency domain resource, the same interlace size, the same DMRS scrambling ID which is related to the PDCCH, the same granularity for precoding, the same set of transmission control information, the same offset directory, or the same number of resource group bindings.

According to the M CORESET information configured by the base station or the M SS information configured by the base station and the repeating DCI rules specified by the base station, the UE determines the position of the time-frequency resource of the blind demodulated DCI, the number of DCI requiring blind demodulation, and the position of the time-frequency resource recurring DCI resource.

In an embodiment, the definition of N repeat DCI fragments in a DCI set includes at least one of the following. The N DCI fragments satisfying the repetitive high layer signaling rule in the DCI set are defined as repetitive DCI; N DCI fragments having a search space indicator area (SSREF) in a search space (SS) in a DCI set are defined as a repeated DCI; or N DCI fragments having a control resource pointer area (CORESETREF) in a control resource set (CORESET) in the DCI set is defined as a repeating DCI; wherein each of all regions included in the N DCI tiles has the same content.

In an embodiment, determining the N repeat DCI fragments in the DCI set may be that the UE detects that each of the first SS and the second SS has an SSREF area, the content in the SSREF areas is SSID2 and SSID1 respectively, SSID1 corresponds to the first SS, and SSID2 corresponds to the second SS, so the DCI in the first SS and the DCI in the second SS are defined as repeated DCI.

In an embodiment, determining the N repeat DCI fragments in the DCI set may also be that the UE detects that each of the first CORESET and the second CORESET has a CORESETREF region, the content in the CORESETREF regions is CORESETID2 and CORESETID1 respectively, CORESETID1 corresponds to the first CORESET, and CORESETID2 corresponds to the second CORESET, so the DCI in the first CORESET and the DCI in the second CORESET are defined as a repeating DCI.

In an embodiment, determining the N repeating DCI fragments in the DCI set may also include that when at least one or more of the same first information elements are found in the SS, the DCI in the SS is determined to be the repeating DCI. The first information element may comprise at least one of a first duration, a monitoring interval period, a monitoring interval period offset, a number of candidate PDDCHs, a DCI format, or a symbol position within the monitoring interval.

In an embodiment, determining the N repeating DCI fragments in the DCI set may also include that when at least one or more of the same second information elements are found in the CORESET, the DCI in the CORESET is determined to be the repeating DCI. The second information element may comprise at least one of the following: a second duration, a type of mapping of a control channel element to a group of resource elements, a frequency domain resource, an interlace size, a DMRS scrambling ID that is related to the PDCCH, a split rate for precoding, a set of control information transfer, shift directory, or number of resource group bindings.

In S120, the correlated DCI information in the DCI set is determined according to the repeated DCI.

In an embodiment, determining correlated DCI information in a DCI set according to a repeated DCI includes one of the following courses of action.

The value of the downlink assignment index (DAI) of the DCI set is determined according to the repeated DCI; a transmission interval of the resource coordinated by the repeated DCI is determined according to the repeated DCI; a redundancy version (RV) of the repeating DCI is determined according to the repeating DCI; the DAI value of the DCI set and the transmission interval of the resource coordinated by the repeated DCI are determined according to the repeated DCI; or a downlink assignment index (DAI) value of the DCI set and a redundancy version (RV) of the repeating DCI is determined according to the repeating DCI.

The DCI set contains M DCI fragments. The M DCI fragments contain N repeat DCI fragments and M-N non-repeated DCI fragments. The first DCI subset contains N repeat DCI fragments. M is a positive integer, and M > N.

In an embodiment, the value of the downlink assignment index (DAI) of the DCI set is determined according to the repeated DCI.

In an embodiment, determining a DCI set downlink assignment index (DAI) value according to the repeated DCI includes determining the DCI set DAI value according to a detection result of N repeated DCI fragments in the first DCI subset, wherein the repeated DCI DAI in the first DCI subset has the same value.

In this embodiment of the present invention, the UE can determine at what positions the DCI is repetitive according to the reference information of the base station. In FIG. 3 is a diagram of the DAI value when all repetitive DCI is detected according to the present invention. As shown in FIG. 3, the UE sequentially blindly demodulates the DCI at (event 0, CC0), (event 0, CC1), (event 0, CC2), (event 1, CC0) and (event 1, CC1) and knows that the DCI is at ( event 0, CC0) and DCI in (event 1, CC0) are recurring. That is, in FIG. 3 DCI equal to 1 at the position of the dotted box and DCI equal to 1 at the position of the continuous box are repeated. However, when the UE blindly demodulates the DCI, it cannot be guaranteed that the entire DCI will be correctly demodulated, and it is necessary to consider a condition for detecting repeated DCI and how to solve the problem of DAI mismatch.

In FIG. 4 is a DAI calculation scheme according to the present invention. As shown in FIG. 4, the calculation of the DAI value is the addition of 1 modulo 4 of the result after accumulation according to the sequence of the first time domain and then the frequency domain.

In an embodiment, if no duplicate DCI is detected in the first DCI subset, the DAI value of the DCI set is determined according to the actually detected DCI sequence. In FIG. 5 is a diagram of the DAI value when no repetitive DCI is detected according to the present invention. As shown in FIG. 5, repeated DCI is not detected. That is, in FIG. 5 do not detect 1 at the position of the continuous box and 1 at the position of the dotted box, so the UE calculates the DAI value according to the actually detected DCI sequence and not the reserved DAI value in the DCI. That is, the total DAI value is 123 instead of 234.

In an embodiment, if at least one repeating DCI fragment is detected in the first DCI subset, then the DCI having the minimum time domain event index and the minimum carrier spacing parameter in the first DCI subset is determined as the target DCI, the DAI in the first DCI subset is placed at position the target DCI and the DCI set DAI value are determined according to the target DCI DAI and the non-repeating DCI DAI in the DCI set, the DAI position being jointly determined by the time domain event index and the component carrier index.

The value of the DAI at the position of the non-repeating DCI in the first DCI subset is omitted, the relative sequence between the DAI of the non-repeating DCI in the DCI set remains unchanged, and the relative sequence between the DAI of the non-repeating DCI in the DCI set and the DAI of the target DCI remains unchanged, and the value of the DAI of the non-repeating DCI in the DCI set is determined according to the content of the DAI area in the detected DCI.

In FIG. 3 is a diagram of the DAI value when all repetitive DCI is detected according to the present invention. As shown in FIG. 3, two DCI fragments are detected, i.e. 1 is detected at the position of the continuous box and 1 is detected at the position of the dotted box. The UE determines that the DCI at positions 1 in the continuous box and the dashed box is repeated according to the detection result and the base station configuration, and the DAI value after blind demodulation is 12314. In this case, the UE knew that 1 in the first continuous box and 1 in the second dashed box. box are repeated, the target DCI in the repeated DCI is at position 1 in the first continuous box, and the resulting DAI is 1234.

In FIG. 6 is a diagram of the DAI value when only anterior repetitive DCI is detected according to the present invention. Only the most forward repeating DCI is detected. That is, in FIG. 6 detects a 1 in a continuous box, while a 1 in a dotted box is not detected. The target DCI in the repeated DCI is at position 1 in the first contiguous rectangle, and the DAI value is 1234 after the blind demodulation performed by the UE, which is a normal value.

In FIG. 7 is a diagram of the DAI value when only posterior repetitive DCI is detected according to the present invention. Only the rearmost repeating DCI is detected. That is, in FIG. 7 1 in a continuous box is not detected while 1 in a dotted box is detected. The DAI value is 2341 after the blind demodulation performed by the UE. The UE knows that a DCI of 1 in a continuous box and a DCI of 1 in a dotted box are repeated. Although no DCI at position 1 in the continuous box is detected, the target DCI in the repeating DCI is at position 1 in the first continuous box, so the resulting DAI is 1234.

In FIG. 8 is a sequence diagram of the resulting DAI when at least one repetitive DCI fragment is detected, according to the present invention. In the previous three cases in which at least one repeating DCI fragment is detected, the resulting repeating DCI DAI should be placed at the DCI position having the minimum time domain event index and the minimum component carrier index in the repeating DCI, which corresponds to position 1 in the contiguous rectangle on fig. 8, and the resulting DAI value is 1234, which is obtained according to OR operations.

In an embodiment, the transmission interval of the resource coordinated by the recurring DCI is determined according to the recurring DCI.

In an embodiment, determining the N repeating DCI fragments in the DCI set includes defining the N DCI fragments that satisfy the repeated high layer signaling rule in the DCI set as a repeating DCI; determining N DCI fragments having a search space indicator area (SSREF) in a search space (SS) in the DCI set as a repeated DCI; and defining N DCI fragments having a control resource pointer area (CORESETREF) in a control resource set (CORESET) in the DCI set as a repeating DCI; wherein each of all regions included in the N DCI tiles has the same content.

In this embodiment, the definition of N repeat DCI fragments in the DCI set is essentially the same as the definition of N repeat DCI fragments in the DCI set provided in the previous embodiment, and the implementation may refer to the description in the previous embodiment and thus, will not be repeated in this embodiment.

In an embodiment, the resource type coordinated by the recurring DCI and the number of resources coordinated by the recurring DCI are determined, wherein the resource type comprises at least one of the following: Physical Downlink Shared Channel (PDSCH), Physical Uplink Shared Channel (PUSCH), or aperiodic sounding reference signal (AP SRS).

N repeating DCI fragments are transmitted in N different transmission intervals, and the repeating DCI coordinates the same resource.

In an embodiment, the method further includes receiving configured first resource information, the first resource information comprising a type of resource coordinated by the repeating DCI, a number of resources coordinated by the repeating DCI, and a reference DCI of the resource coordinated by the repeating DCI; and the resource type comprises at least one of a physical downlink common channel (PDSCH), a physical uplink common channel (PUSCH), or an aperiodic sounding reference signal (AP SRS). The first resource information is configured by the base station.

In an embodiment, determining a recurring DCI-coordinated resource transmission interval includes determining, according to the reference DCI N fragments of the recurring DCI, a resource transmission interval coordinated by the recurring DCI. The anchor DCI comprises at least one of the following: a DCI having a minimum transmission interval among the N fragments of the repeated DCI; a DCI having a maximum transmission interval among the N fragments of the repeated DCI; a DCI corresponding to the minimum control resource set identifier among the N repeating DCI fragments; a DCI corresponding to the maximum control resource set identifier among the N repeating DCI fragments; a DCI corresponding to the minimum search space identifier among the N fragments of the repeated DCI; or a DCI corresponding to the maximum search space identifier among the N fragments of the repeated DCI.

In an embodiment, the base station configures M CORESET or M SS for the UE and indicates to the UE that the DCI in the N CORESET is repetitive, or that the DCI in the N SS is repetitive, where M and N are positive integers and M > N > 1 , for example, M = 4, and N = 2.

The base station is configured such that a repeating DCI can only coordinate one PDSCH in different slots.

The base station is configured such that a repeating DCI can coordinate only one PDSCH in different intervals, and the DCI having the minimum transmission interval determines the position of the PDSCH.

According to the M CORESET information configured by the base station or the M SS information configured by the base station and the repeating DCI rules specified by the base station, the UE determines the position of the time-frequency resource of the blind demodulated DCI, the number of DCI requiring blind demodulation, and the position of the time-frequency resource recurring DCI resource.

The UE determines the type of the final coordinated resource and the amount of the final coordinated resource according to the number of PDSCH resources that can be coordinated by the repeated DCI configured by the base station and the repeated DCI detection condition after blind demodulation.
