[0024] The behavior determination method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.
[0025] Please see Figure 2 , Figure 2 This is a flowchart of a behavior determination method provided in an embodiment of this application. The behavior determination method includes:
[0026] Step 201: The terminal acquires target information, which is associated with multiple candidate resources for repeated transmission of the Physical Downlink Control Channel (PDCCH). For example, the target information includes Downlink Control Information (DCI) carrying a minimum scheduling slot offset indication, which is transmitted through the multiple candidate resources; or, the target information includes configuration information for the multiple candidate resources, which can be dynamically configured or pre-configured by network-side devices, without limitation here.
[0027] Step 202: The terminal determines its behavior based on the target information.
[0028] In this embodiment, the terminal acquires target information, which is associated with multiple candidate resources for repeated PDCCH transmission. Based on this target information, the terminal determines its behavior. The terminal can determine its behavior based on the target information, avoiding ambiguity in its behavior.
[0029] In one embodiment of this application, the target information includes a DCI carrying a minimum scheduling slot offset indication, and the DCI is transmitted through the plurality of candidate resources;
[0030] The terminal determines its behavior based on the target information, including:
[0031] The terminal determines the scheduling time slot delay value based on whether the reference PDCCH candidate resource is within the first n Orthogonal Frequency Division Multiplex (OFDM) symbols of the current time slot, where n is a positive integer; wherein, the reference PDCCH candidate resource is the latest PDCCH candidate resource among the multiple candidate resources.
[0032] In the above, the DCI carries a minimum scheduling slot offset indication, and the DCI is transmitted through multiple candidate resources for PDCCH repetition transmission. The terminal can determine different scheduling slot delay values based on whether the reference PDCCH candidate resource is within or outside the first n (e.g., the first 3) OFDM symbols of the current slot.
[0033] In one implementation, the minimum scheduling slot offset can be used to determine the scheduling slot delay value. In another implementation, the terminal can trigger itself to determine the scheduling slot delay value based on carrying the minimum scheduling slot offset indicator (DCI). That is, the terminal triggers itself to determine the scheduling slot delay value based on the target information and whether the reference PDCCH candidate resource is within the first n orthogonal frequency division multiplexing (OFDM) symbols of the current slot.
[0034] The latest PDCCH candidate resource is either the candidate resource with the latest start position among the plurality of candidate resources, or the candidate resource with the latest end position among the plurality of candidate resources. For example, the latest PDCCH candidate resource can be determined based on the temporal transmission order of the starting OFDM symbols of each PDCCH candidate resource, or it can be determined based on the temporal transmission order of the end positions of each PDCCH candidate resource.
[0035] Furthermore, if the start or end position of the reference PDCCH candidate resource is within the first n OFDM symbols of the current time slot, the scheduling time slot delay value of the terminal is the first scheduling time slot delay value.
[0036] If the start or end position of the reference PDCCH candidate resource is outside the first n OFDM symbols of the current time slot, the scheduling time slot delay value of the terminal is the second scheduling time slot delay value.
[0037] For example, if the starting OFDM symbol position of the reference PDCCH candidate resource is within the first 3 OFDM symbols, then the first scheduling slot delay value is determined; if the starting OFDM symbol position of the reference PDCCH candidate resource is outside the first 3 OFDM symbols, then the second scheduling slot delay value is determined.
[0038] Alternatively, if the end position of the reference PDCCH candidate resource is within the first 3 OFDM symbols, then the first scheduling slot delay value is determined; if the end position of the reference PDCCH candidate resource is outside the first 3 OFDM symbols, then the second scheduling slot delay value is determined.
[0039] In one embodiment of this application, when the terminal is configured with a search space switching function, the search spaces corresponding to the plurality of candidate resources each have the same search space group index.
[0040] In one embodiment of this application, the target information includes a first PDCCH and a second PDCCH, wherein the first PDCCH carries Bandwidth Part (BWP) switching information, the second PDCCH carries Channel State Information (CSI) triggering information, and the active BWP where the second PDCCH is located and the active BWP where the terminal receiving non-zero power CSI-RS is located are different BWPs.
[0041] Specifically, the first PDCCH candidate resource is the latest PDCCH candidate resource among the N PDCCH candidate resources occupied by the first PDCCH configuration, the second PDCCH candidate resource is the latest PDCCH candidate resource among the M PDCCH resources occupied by the second PDCCH configuration, and the third PDCCH candidate resource is the earliest PDCCH candidate resource among the M PDCCH resources occupied by the second PDCCH configuration.
[0042] The end position of the span occupied by the first PDCCH candidate resource (e.g., the last OFDM symbol) is no later than the end position of the span occupied by the second PDCCH candidate resource (e.g., the last OFDM symbol); or, the end position of the span occupied by the first PDCCH candidate resource is no later than the end position of the span occupied by the third PDCCH candidate resource; wherein, N is greater than or equal to 1, and M is greater than or equal to 1. N>1 indicates that the first PDCCH is configured for repeated transmission; M>1 indicates that the second PDCCH is configured for repeated transmission.
[0043] In the above, the latest PDCCH candidate resource can be determined based on the temporal transmission order of the starting OFDM symbols of each PDCCH candidate resource, or based on the temporal transmission order of the ending position of each PDCCH candidate resource. That is, the latest PDCCH candidate resource among the N PDCCH candidate resources is:
[0044] The candidate resource with the latest start position (e.g., the latest start time of the OFDM symbol) among N PDCCH candidate resources; or the candidate resource with the latest end position (e.g., the latest time of the last OFDM symbol) among N PDCCH candidate resources.
[0045] The latest PDCCH candidate resource among the M PDCCH candidate resources is:
[0046] The candidate resource with the latest start position (e.g., the latest start time of the OFDM symbol) among the M PDCCH candidate resources; or the candidate resource with the latest end position (e.g., the latest end time of the last OFDM symbol) among the M PDCCH candidate resources.
[0047] In one embodiment of this application, the terminal determines terminal behavior based on the target information, including:
[0048] If, based on the target information, it is determined that the fourth PDCCH candidate resource among the plurality of candidate resources overlaps with the radio frequency switching time of the terminal or the time of transmitting a Sounding Reference Signal (SRS) on other carrier frequencies, the terminal does not listen to the fourth PDCCH candidate resource, and the terminal determines that the PDCCH configured for detection is a repeated transmission.
[0049] As described above, the target information may include configuration information for multiple candidate resources, which can be dynamically configured or pre-configured by network-side devices. Based on the target information, it can be determined that the fourth PDCCH candidate resource overlaps with the terminal's radio frequency switching time or with the time of SRS transmission on other carrier frequencies. In this case, the terminal does not listen to the fourth PDCCH candidate resource, and the terminal determines that the PDCCH configured for detection is a duplicate transmission. The fourth PDCCH candidate resource may be one or more of the multiple candidate resources.
[0050] In one embodiment of this application, the terminal determines terminal behavior based on the target information, including:
[0051] If the fifth PDCCH candidate resource among the plurality of candidate resources is determined to meet the preset conditions based on the target information, the terminal does not listen to the fifth PDCCH candidate resource;
[0052] If the time-frequency resources of the fifth PDCCH candidate resource and the time-frequency resources of the PDSCH scheduled for repeated transmission of the PDCCH partially overlap, the terminal demodulates the PDSCH according to at least one of the following:
[0053] The terminal considers that the overlapping resources are not used to carry PDSCH, and performs rate matching on the overlapping resources;
[0054] The terminal considers the overlapping resources to be used to carry PDSCH and does not perform rate matching on the overlapping resources;
[0055] If the preset conditions are configured through Radio Resource Control (RRC), the terminal considers the overlapping resources to be used to carry PDSCH and does not perform rate matching on the overlapping resources;
[0056] If the preset conditions are configured via DCI, the terminal considers that the overlapping resources are not used to carry PDSCH and performs rate matching on the overlapping resources.
[0057] Based on the network-side device configuration or indication, the terminal considers that the overlapping resources are not used to carry PDSCH, and performs rate matching on the overlapping resources;
[0058] Based on the network-side device configuration or indication, the terminal considers the overlapping resources to be used to carry PDSCH and does not perform rate matching on the overlapping resources.
[0059] The DCI is transmitted repeatedly by occupying multiple candidate resources. The time-frequency resources of the PDSCH are scheduled through the DCI. The fifth PDCCH candidate resource is one or more of the multiple candidate resources.
[0060] In the above, the terminal may, based on preset conditions, choose not to listen to a candidate resource of a repeatedly transmitted PDCCH (i.e., the fifth PDCCH candidate resource). If the time-frequency resources configured for the PDCCH candidate resource (including the DMRS resources of the PDCCH) overlap with the scheduled PDSCH time-frequency resources, when the terminal receives and demodulates the PDSCH, it may select at least one of the following for demodulation:
[0061] a) Although the network-side equipment did not actually send the fifth PDCCH candidate resource, the terminal still believed that the overlapping resources were not used to carry PDSCH transmission signals;
[0062] b) Since the network-side equipment did not actually send the fifth PDCCH candidate resource, the terminal believed that the overlapping resources could be used to carry the PDSCH transmission signal;
[0063] c) When the preset conditions are configured via RRC, select b); when the preset conditions are configured dynamically via DCI, select a).
[0064] d) Select either a) or b) based on the network-side device configuration or instructions.
[0065] Furthermore, the preset condition includes one of the following:
[0066] The time-frequency resources of the fifth PDCCH candidate resource overlap with the time-domain resources of the Synchronization Signal Block (SSB).
[0067] The time-frequency resources of the fifth PDCCH candidate resource overlap with the time-frequency resources of the target resource configured by the higher layer of the network-side equipment;
[0068] The time-frequency resources of the fifth PDCCH candidate resource overlap with the time-frequency resources of the uplink transmission signal;
[0069] The time-frequency resources of the fifth PDCCH candidate resource overlap with the radio frequency adjustment time.
[0070] The target resources mentioned above include the following resources configured at higher levels of the network-side devices:
[0071] RateMatchPattern, lte-CRS-ToMatchAround, LTE-CRS-PatternList-r16 or availableRB-SetPerCell-r16.
[0072] In one embodiment of this application, the terminal determines terminal behavior based on the target information, including:
[0073] Based on the target information, when it is determined that the starting control channel element (CCE) index of the first aggregation level PDCCH candidate resource and the second aggregation level PDCCH candidate resource is the same at the listening time, and the control resource set (CORESET) associated with the first aggregation level PDCCH candidate resource and the second aggregation level PDCCH candidate resource is configured for non-interleaving, and the CORESET is configured with m OFDM symbols, the terminal behavior is determined.
[0074] Where m is a positive integer, and the second aggregation level is higher than the first aggregation level.
[0075] The terminal behavior includes at least one of the following:
[0076] If the PDCCH of the second aggregation level is configured for repeated transmission, the PDCCH of the first aggregation level is configured for separate transmission, and the starting CCE index of the PDCCH candidate resource of the first aggregation level and the PDCCH candidate resource of the second aggregation level are the same at the listening time, if the terminal successfully listens according to the first aggregation level, the terminal considers the successfully listened PDCCH to be the PDCCH of the second aggregation level, and the terminal considers that the PDCCH candidate resource of the second aggregation level and other repeatedly transmitted PDCCH candidate resources of the second aggregation level at the same listening time cannot be used for Physical downlink shared channel (PDSCH) signal transmission.
[0077] If the PDCCH of the first aggregation level is configured for repeated transmission, the PDCCH of the second aggregation level is configured for individual transmission, and the starting CCE index of the PDCCH candidate resource of the second aggregation level and one of the PDCCH candidate resources of the first aggregation level are the same at the listening time, if the terminal successfully listens according to the first aggregation level, the terminal considers the successfully listened PDCCH to be the PDCCH of the first aggregation level, and the terminal considers that only the time-frequency resources of the PDCCH of the first aggregation level cannot be used for PDSCH signal transmission at the listening time; or, the terminal considers that the time-frequency resources of the PDCCH of the second aggregation level cannot be used for PDSCH signal transmission at the listening time.
[0078] If the PDCCH of the first aggregation level is configured for repeated transmission and the PDCCH of the second aggregation level is configured for repeated transmission, and at at least one listening time, the starting CCE index of a PDCCH candidate resource of the first aggregation level is the same as the starting CCE index of a PDCCH candidate resource of the second aggregation level, if the terminal successfully listens according to the first aggregation level, then the terminal considers the successfully listened PDCCH to be the PDCCH of the second aggregation level, and the terminal considers that the PDCCH candidate resource of the second aggregation level and other repeatedly transmitted PDCCH candidate resources of the second aggregation level at the same listening time cannot be used for PDSCH signal transmission;
[0079] When the PDCCH of the second aggregation level is configured for repeated transmission, the PDCCH of the first aggregation level is configured for individual transmission, and the starting CCE index of the PDCCH candidate resource of the first aggregation level and the PDCCH candidate resource of the second aggregation level are the same at the listening time, the terminal listens only according to the first aggregation level or the second aggregation level, or the terminal selects the aggregation level with the PDCCH configured for repeated transmission for listening.
[0080] If the PDCCH of the first aggregation level is configured for repeated transmission, the PDCCH of the second aggregation level is configured for individual transmission, and the starting CCE index of the PDCCH candidate resource of the second aggregation level and one of the PDCCH candidate resources of the first aggregation level are the same at the listening time, the terminal listens only according to the first aggregation level or the second aggregation level, or the terminal selects the aggregation level with the PDCCH configured for repeated transmission for listening.
[0081] When the PDCCH of the first aggregation level is configured for repeated transmission and the PDCCH of the second aggregation level is configured for repeated transmission, if at least one listening opportunity occurs and the starting CCE index of a PDCCH candidate resource of the first aggregation level is the same as the starting CCE index of a PDCCH candidate resource of the second aggregation level, the terminal listens only according to the first aggregation level or the second aggregation level.
[0082] The following example illustrates the above embodiments using AL8 as the first polymerization level and AL16 as the second polymerization level.
[0083] When a terminal listens to the PDCCH candidate resources of AL8 and AL16, and at a certain listening time, the starting CCE index of the PDCCH candidate resources of AL8 and AL16 is the same, and the corresponding CORESET is configured with non-interleaving and one OFDM symbol, the terminal determines whether these PDCCH candidate resources should be used for PDSCH signal transmission based on whether the PDCCH candidate resources of AL8 and AL16 are repeatedly transmitted. This can be categorized into the following cases:
[0084] 1) When the PDCCH candidate resource of AL16 is configured for repeated transmission, but the PDCCH candidate resource of AL8 is configured for separate transmission, and at a certain listening time, the starting CCE index is the same as that of one of the PDCCH candidate resources of AL16. If the terminal successfully listens at the aggregation level AL8, the terminal considers the successfully listened PDCCH to be a repeated transmission of aggregation level AL16, and the terminal considers that the PDCCH candidate resource of AL16 at the same listening time, as well as other associated repeated transmissions of AL16 PDCCH candidate resources, cannot be used for PDSCH signal transmission.
[0085] 2) When the PDCCH candidate resource of AL8 is configured for repeated transmission, but the PDCCH candidate resource of AL16 is configured for separate transmission, and at a certain listening time, the starting CCE index is the same as that of one of the PDCCH candidate resources of AL8. If the terminal successfully listens at the aggregation level AL8, the terminal considers the successfully listened PDCCH to be a repeated transmission behavior of aggregation level AL8, and the terminal considers that only the PDCCH time-frequency resource of AL8 cannot be used for PDSCH signal transmission at that listening time, or alternatively, that the PDCCH time-frequency resource of AL16 cannot be used for PDSCH signal transmission.
[0086] 3) When the PDCCH candidate resource of AL8 is configured for repeated transmission, and the PDCCH candidate resource of AL16 is also configured for repeated transmission, if at least one listening time, the starting CCE index of a PDCCH candidate resource of AL8 and the starting CCE index of a PDCCH candidate resource of AL16 are the same, and the terminal successfully listens at the aggregation level AL8, the terminal considers the successfully listened PDCCH to be a repeated transmission of aggregation level AL16, and the terminal considers that the PDCCH candidate resource of AL16 at the same listening time, as well as other associated repeated transmissions of AL16 PDCCH candidate resources, cannot be used for PDSCH signal transmission.
[0087] In addition, the terminal may have the following possible behavioral limitations:
[0088] Behavior 1: In the above three cases, the terminal only expects to select one aggregation level to listen to, such as only AL8 or AL16, or only the aggregation level configured to listen to PDCCH for repeated transmission (for the first two cases above).
[0089] Behavior 2: The terminal does not expect either the AL8 PDCCH repetition or the AL16 PDCCH repetition to be configured to be sent repeatedly in the above scenario.
[0090] In one embodiment of this application, when the terminal does not support the ability to listen to candidate resources of PDCCH independently, the non-repeating PDCCH is transmitted on the sixth PDCCH candidate resource, which comes from the search space with the smallest identifier ID among at least two associated search spaces for PDCCH repetition transmission.
[0091] Specifically, when the network-side device learns that the terminal does not support the ability to listen to PDCCH independently as a candidate (the capability can be reported by the terminal or a default terminal capability), the terminal expects the network to send a single PDCCH only on the first PDCCH candidate. The first PDCCH candidate comes from the search space with the smallest ID in two associated search spaces used for PDCCH retransmission.
[0092] In one embodiment of this application, L1 candidate resources among the plurality of candidate resources have temporal overlap, the L1 candidate resources are associated with K CORESETs, and the K CORESETs are associated with different QCL-typeD (quasi-collocation, QCL) information;
[0093] If the terminal receives a PDCCH on the current symbol and receives Channel State Information Reference Signals (CSI-RS) resources on the current symbol, and the CSI-RS set associated with the CSI-RS resources is configured with the repeat transmission parameter enabled off, then the QCL-typeD information of the CSI-RS is the same as the QCL-typeD information of the target reference CORESET in the K CORESETs.
[0094] Wherein, the current symbol is the symbol in the time overlap, the L1 candidate resources include at least two candidate resources carrying the same DCI, or the L1 candidate resources include at least two candidate resources carrying different DCIs; L1 is an integer greater than 1, K is an integer greater than 1, and L1 is greater than or equal to K.
[0095] In the above, L1 candidate resources are associated with K CORESETs. This can be understood as each candidate resource in L1 candidate resources being associated with one CORESET, and different candidate resources may be associated with the same or different CORESETs.
[0096] In the above, the L1 candidate resources are all candidate resources for PDCCH retransmission, but not necessarily for PDCCH retransmission for the same purpose. The L1 candidate resources include at least two candidate resources carrying the same DCI, or the L1 candidate resources include at least two candidate resources carrying different DCIs. At least two candidate resources carrying the same DCI can be understood as being used for PDCCH retransmission for the same purpose, and at least two candidate resources carrying different DCIs can be understood as being used for PDCCH retransmission for different purposes.
[0097] In one embodiment of this application, the target PDCCH resource overlaps with L2 candidate resources among the plurality of candidate resources in time. The target PDCCH resource and the L2 candidate resources are associated with K CORESETs, and the K CORESETs are associated with different QCL-typeD information.
[0098] If the terminal receives a PDCCH on the current symbol and receives a CSI-RS resource on the current symbol, and the CSI-RS set associated with the CSI-RS resource is configured with the repeat transmission parameter enable off, then the QCL-typeD information of the CSI-RS is the same as the QCL-typeD information of the target reference CORESET in the K CORESETs.
[0099] Wherein, the target PDCCH resource is a candidate resource not used for PDCCH retransmission, the current symbol is a symbol in the time overlap, the target PDCCH resource and at least one of the L2 candidate resources carry the same DCI, or the target PDCCH resource and at least one of the L2 candidate resources carry different DCIs; L2 is a positive integer, and K is an integer greater than 1.
[0100] In the above, the target PDCCH resource and the L2 candidate resources are associated with K CORESETs. This can be understood as each resource in the target PDCCH resource and the L2 candidate resources being associated with one CORESET, and the CORESETs associated with different resources can be the same or different.
[0101] In the above, the L2 candidate resources are all candidate resources for PDCCH retransmission. The target PDCCH resource and these L2 candidate resources are not necessarily used for the same purpose of PDCCH retransmission. The target PDCCH resource and at least one of the L2 candidate resources carry the same DCI, or the target PDCCH resource and at least one of the L2 candidate resources carry different DCIs. At least two candidate resources carrying the same DCI can be understood as being used for the same purpose of PDCCH retransmission, and at least two candidate resources carrying different DCIs can be understood as being used for different purposes of PDCCH retransmission.
[0102] Furthermore, when the current symbol is within the preset default receive beam time threshold, the QCL-typeD information of the PDSCH received by the terminal on the current symbol is the same as the QCL-typeD information of the target reference CORESET among the K CORESETs, wherein the target reference CORESET is the CORESET with the smallest identifier among the K CORESETs.
[0103] The following provides illustrative examples of the implementation methods provided in this application.
[0104] Implementation Method 1: When the UE detects a DCI format 0_1 or 1_1 containing the Minimum applicable scheduling offset indicator field, the K indicated by the Minimum applicable scheduling offset indicator field... 0min and K 2min Before it takes effect, the currently valid K 0min and K 2min It will remain in effect.
[0105] When a UE detects a DCI format 0_1 or 1_1 containing the Minimum applicable scheduling offset indicator field on the nth slot, and this DCI simultaneously indicates a target activation of downlink or uplink BWP handover for the serving cell, the K indicated by the DCI... 0min (K 2min (Associated with the target activation BWP, DCI indicates K) 0min (K 2min It takes effect from the time slot corresponding to K0 / K2 indicated by the TDRA field of the DCI.
[0106] When a UE detects a DCI format 0_1 or 1_1 containing the Minimum applicable scheduling offset indicator field on the nth slot, and this DCI does not indicate the target activation of downlink or uplink BWP handover for the serving cell, then the K indicated by this DCI... 0min (K 2min The activation will begin in the (n+X)th time slot of the scheduling cell. From the (n+1)th time slot until the (n+X)th time slot, the UE does not expect to receive another K indicating the same activated BWP in the scheduled cell. 0min (K 2min DCI value changes.
[0107] When the indicator K 0min (K 2min When the changed DCI is located in the first three OFDM symbols of slot n, the new K 0min (K 2min The application delay value X is calculated according to the following formula (1):
[0108]
[0109] Among them, K 0minOld It is the currently active K of the activated downlink BWP of the scheduled cell. 0min Value, if the base station is not configured with this value, then K 0min It equals 0. Zμ is determined by the subcarrier spacing μ of the downlink BWP activated by the scheduling cell in the nth time slot. The specific correspondence is shown in Table 1 below. μPDCCH and μPDSCH are the subcarrier spacing of the PDCCH of the downlink BWP activated by the scheduling cell in the nth time slot and the subcarrier spacing of the PDSCH of the downlink BWP activated by the scheduled cell in the nth time slot, respectively.
[0110] During cross-carrier scheduling, if the scheduling cell indicates the K of the scheduled cell in time slot n... 0min or K 2min If the K value is changed, and a downlink active BWP handover occurs in the scheduled cell before time slot n+X, then the new K value... 0min and / or K 2min The time slot in which the value takes effect is no earlier than the start time of time slot n+X, where the value of X is determined according to the above formula (1), and the μPDCCH of formula (1) is determined by the subcarrier spacing of the active downlink carrier of the scheduling cell in time slot n.
[0111] When the indicator K 0min or K 2min When the changed DCI is located in a symbol other than the first three symbols of slot n, in order to compensate for the impact of the PDCCH occupying a symbol that is relatively late in the slot, the new K... 0min or K 2min The application delay value X is obtained by adding 1 to the value calculated by expression 1 (as shown in expression 2 below).

[0115] When the DCI carries a minimum scheduling slot offset indication, and the DCI is transmitted via PDCCH repetition (e.g.) Figure 3aAs shown, different scheduling slot delay values are determined based on whether the reference PDCCH candidate is within or outside the first three OFDM symbols of the current slot. The reference PDCCH candidate refers to the PDCCH candidate that is sent latest in time among the PDCCH repeating candidates. The comparison method for determining which candidate is sent later in time can be based on the time order of the first OFDM symbols of each PDCCH repeating candidate, or it can be based on the time order of the last OFDM symbol of each PDCCH repeating candidate. Figure 3a In the process, the second duplicate PDCCH candidate is used as the reference PDCCH candidate because it was sent later in time. Then, to determine whether the reference PDCCH candidate is within or outside the first three OFDM symbols, the last OFDM symbol of that PDCCH candidate can be used as a reference. Figure 3a If the last OFDM symbol of the PDCCH candidate exceeds the previous 3 OFDM symbols, then the second scheduling slot delay value is executed, which is the value determined by formula (2) in the above description.
[0116] Implementation Method Two:
[0117] When the first PDCCH carries BWP handover information and the second PDCCH carries a CSI trigger information, the following two methods are included:
[0118] Method 1: For example Figure 3b As shown, the last OFDM symbol of the span occupied by the latest PDCCH candidate among the two PDCCH candidates occupied by the first PDCCH cannot be later than the last OFDM symbol of the span occupied by the latest PDCCH candidate among the two PDCCH candidates occupied by the second PDCCH.
[0119] Method 2: For example Figure 3c As shown, the last OFDM symbol of the span occupied by the latest PDCCH candidate among the two PDCCH candidates occupied by the first PDCCH cannot be later than the last OFDM symbol of the span occupied by the earliest PDCCH candidate among the two PDCCH candidates occupied by the second PDCCH.
[0120] Implementation Method 3:
[0121] As shown in the 3D diagram, the two associated PDCCHs are being transmitted repeatedly, and the timing of the second PDCCH repetition candidate conflicts with the terminal's radio frequency adjustment time (the reason for the radio frequency adjustment could be that a carrier frequency handover or BWP handover is occurring at this time). In this case, the terminal no longer receives the second PDCCH repetition candidate; the terminal only receives the first PDCCH repetition candidate. The terminal still considers the monitored PDCCH to be a repeated transmission, and this does not affect the rules for pre-calculating blind detection capabilities in the network or the terminal.
[0122] Implementation Method Four:
[0123] like Figure 3e As shown, the two associated PDCCHs are transmitted repeatedly, and the second PDCCH repetition candidate overlaps with the SSB time-frequency resources. The terminal will not listen for PDCCHs on this candidate; therefore, it can be assumed that the base station will not transmit this PDCCH on it either, but only on the first repetition candidate. Since some of the PDSCH time-frequency resources scheduled in the DCI overlap with the second PDCCH repetition candidate (as shown in the gray area in the figure), there are two possible assumptions regarding whether the terminal assumes that the gray area transmitted PDSCH information when receiving the PDSCH.
[0124] Option 1: PDSCH on the gray areas in the image (i.e. Figure 3e Rate matching is performed at the overlapping positions of PDCCH and PDSCH.
[0125] Option 2: PDSCH does not perform rate matching on the gray areas in the diagram.
[0126] Implementation Method 5:
[0127] When a terminal listens to the PDCCH candidates at aggregation levels AL8 and AL16, and at a certain listening time, the starting CCE indexes of the AL8 and AL16 PDCCH candidates are the same, and the corresponding CORESETs are configured with non-interleaving and one OFDM symbol, the terminal determines whether these PDCCH candidates should be used for PDSCH signal transmission based on whether the AL8 and AL16 PDCCH candidates are repeatedly transmitted. This can be categorized into the following scenarios:
[0128] 1. When the AL16 PDCCH candidate is configured for repeated transmission, but the AL8 PDCCH candidate is transmitted separately, and at a certain listening time, its starting CCE index is the same as that of one of the AL16 PDCCH candidates. If the terminal successfully listens at the aggregation level AL8, the terminal considers the successfully listened-to PDCCH to be a repeated transmission of the aggregation level AL16, and the terminal considers that the AL16 PDCCH candidate at the same listening time, as well as other associated repeated transmissions of the AL16 PDCCH candidate, cannot be used for PDSCH signal transmission (e.g., ...). Figure 3f (As shown).
[0129] 2. When the PDCCH candidate of AL8 is configured for repeated transmission, but the PDCCH candidate of AL16 is transmitted separately, and at a certain listening time, its starting CCE index is the same as that of one of the PDCCH candidates of AL8. If the terminal successfully listens according to the aggregation level AL8, the terminal considers the successfully listened PDCCH to be a repeated transmission behavior of aggregation level AL8, and the terminal considers that only the PDCCH time-frequency resources of AL8 cannot be used for PDSCH signal transmission at that listening time, or alternatively, that the PDCCH time-frequency resources of AL16 cannot be used for PDSCH signal transmission (e.g., ...). Figure 3g (As shown).
[0130] 3. When both AL8 and AL16 PDCCH candidates are configured for repeated transmission, and at least at one listening time, the starting CCE index of one AL8 PDCCH candidate and the starting CCE index of one AL16 PDCCH candidate are the same, if the terminal successfully listens at the aggregation level AL8, the terminal considers the successfully listened PDCCH to be a repeated transmission of the aggregation level AL16, and the terminal considers that the AL16 PDCCH candidate at the same listening time, as well as other associated repeated transmissions of the AL16 PDCCH candidate, cannot be used for PDSCH signal transmission (e.g., ...). Figure 3h (As shown).
[0131] Furthermore, to avoid complex solutions in the above three scenarios, the terminal may also have the following behavioral limitations:
[0132] In the three scenarios mentioned above, the terminal only wants to select one aggregation level to listen to, such as only AL8 or AL16, or in the first two scenarios, only the aggregation level configured with PDCCH repetition is selected to listen to.
[0133] It should be noted that the behavior determination method provided in this application embodiment can be executed by a behavior determination device or a control module in the behavior determination device for executing the behavior determination method.

[0158] The candidate resource with the latest start position among the M PDCCH candidate resources; or, the candidate resource with the latest end position among the M PDCCH candidate resources.
[0159] Furthermore, the determining module 402 is configured to not listen to the fourth PDCCH candidate resource when the fourth PDCCH candidate resource among the plurality of candidate resources is determined to overlap with the radio frequency switching time of the terminal or the time of transmitting the probe reference signal SRS on other carrier frequencies, and the terminal determines that the PDCCH configured for detection is a repeated transmission.
[0160] Furthermore, the determining module 402 is configured to not listen to the fifth PDCCH candidate resource when it is determined from the target information that the fifth PDCCH candidate resource among the plurality of candidate resources meets the preset conditions;
[0161] If the time-frequency resources of the fifth PDCCH candidate resource and the time-frequency resources of the PDSCH scheduled for repeated transmission of the PDCCH partially overlap, the terminal demodulates the PDSCH according to at least one of the following:
[0162] The terminal considers that the overlapping resources are not used to carry PDSCH, and performs rate matching on the overlapping resources;
[0163] The terminal considers the overlapping resources to be used to carry PDSCH and does not perform rate matching on the overlapping resources;
[0164] If the preset conditions are configured through Radio Resource Control (RRC), the terminal considers the overlapping resources to be used to carry the Physical Downlink Shared Channel (PDSCH), and does not perform rate matching on the overlapping resources.
[0165] If the preset conditions are configured via DCI, the terminal considers that the overlapping resources are not used to carry PDSCH and performs rate matching on the overlapping resources.
[0166] Based on the network-side device configuration or indication, the terminal considers that the overlapping resources are not used to carry PDSCH, and performs rate matching on the overlapping resources;
[0167] Based on the network-side device configuration or indication, the terminal considers the overlapping resources to be used to carry PDSCH and does not perform rate matching on the overlapping resources.

[0172] The time-frequency resources of the fifth PDCCH candidate resource overlap with the radio frequency adjustment time.
[0173] Furthermore, the determining module 402 is used to determine the terminal behavior when, based on the target information, at the listening time, the starting control channel element (CCE) index of the first aggregation level PDCCH candidate resources and the second aggregation level PDCCH candidate resources are the same, and the control resource set (CORESET) associated with the first aggregation level PDCCH candidate resources and the second aggregation level PDCCH candidate resources is configured as non-interleaved, and the CORESET is configured with m OFDM symbols;
[0174] Where m is a positive integer, and the second aggregation level is higher than the first aggregation level.
[0175] Furthermore, the terminal behavior includes at least one of the following:
[0176] If the PDCCH of the second aggregation level is configured for repeated transmission, the PDCCH of the first aggregation level is configured for separate transmission, and the starting CCE index of the PDCCH candidate resource of the first aggregation level and the PDCCH candidate resource of the second aggregation level are the same at the listening time, if the terminal successfully listens according to the first aggregation level, the terminal considers the successfully listened PDCCH to be the PDCCH of the second aggregation level, and the terminal considers that the PDCCH candidate resource of the second aggregation level and other repeatedly transmitted PDCCH candidate resources of the second aggregation level at the same listening time cannot be used for PDSCH signal transmission;
[0177] If the PDCCH of the first aggregation level is configured for repeated transmission, the PDCCH of the second aggregation level is configured for individual transmission, and the starting CCE index of the PDCCH candidate resource of the second aggregation level and one of the PDCCH candidate resources of the first aggregation level are the same at the listening time, if the terminal successfully listens according to the first aggregation level, the terminal considers the successfully listened PDCCH to be the PDCCH of the first aggregation level, and the terminal considers that only the time-frequency resources of the PDCCH of the first aggregation level cannot be used for PDSCH signal transmission at the listening time; or, the terminal considers that the time-frequency resources of the PDCCH of the second aggregation level cannot be used for PDSCH signal transmission at the listening time.
[0178] If the PDCCH of the first aggregation level is configured for repeated transmission and the PDCCH of the second aggregation level is configured for repeated transmission, and at at least one listening time, the starting CCE index of a PDCCH candidate resource of the first aggregation level is the same as the starting CCE index of a PDCCH candidate resource of the second aggregation level, if the terminal successfully listens according to the first aggregation level, then the terminal considers the successfully listened PDCCH to be the PDCCH of the second aggregation level, and the terminal considers that the PDCCH candidate resource of the second aggregation level and other repeatedly transmitted PDCCH candidate resources of the second aggregation level at the same listening time cannot be used for PDSCH signal transmission;

[0182] Furthermore, if the terminal does not support the ability to listen to candidate resources of PDCCH independently, the non-repeating PDCCH is transmitted on the sixth PDCCH candidate resource, which comes from the search space with the smallest identifier ID among at least two associated search spaces for PDCCH repetition transmission.
[0183] Furthermore, the L1 candidate resources among the multiple candidate resources have temporal overlap, the L1 candidate resources are associated with K CORESETs, and the K CORESETs are associated with different quasi-co-location QCL-typeD information;
[0184] If the terminal receives a PDCCH on the current symbol and receives a CSI-RS resource on the current symbol, and the CSI-RS set associated with the CSI-RS resource is configured with the repeat transmission parameter enable off, then the QCL-typeD information of the CSI-RS is the same as the QCL-typeD information of the target reference CORESET in the K CORESETs.
