[0027] Figure 1 An example wireless communication network and / or system 100, according to an implementation of this disclosure, in which the techniques disclosed herein can be implemented, is illustrated. In the following discussion, wireless communication network 100 can be any wireless network, such as a cellular network or a narrowband Internet of Things (NB-IoT) network, and is referred to herein as "network 100". This exemplary network 100 includes base station 102 (hereinafter referred to as "BS 102") and user equipment device 104 (hereinafter referred to as "UE 104"), which can communicate with each other via communication link 110 (e.g., a wireless communication channel) a cluster of cells 126, 130, 132, 134, 136, 138, and 140 covering a geographic area 101. Figure 1 In this context, BS 102 and UE 104 are contained within the corresponding geographical boundaries of cell 126. Each of the other cells 130, 132, 134, 136, 138, and 140 may include at least one base station operating on its allocated bandwidth to provide sufficient radio coverage to its intended users.

[0028] For example, BS 102 can operate on the allocated channel transmission bandwidth to provide sufficient coverage to UE 104. BS 102 and UE 104 can communicate via downlink radio frame 118 and uplink radio frame 124, respectively. Each radio frame 118 / 124 can be further divided into subframes 120 / 127 that may include data symbols 122 / 128. In this disclosure, BS 102 and UE 104 are described herein as non-limiting examples of "communication nodes" that can practice the methods disclosed herein. According to various implementations of this scheme, such communication nodes are capable of wireless and / or wired communication.

[0029] Figure 2 A block diagram of an example wireless communication system 200 for transmitting and receiving wireless communication signals (e.g., OFDM / OFDMA signals) according to some implementations of this scheme is shown. System 200 may include components and elements configured to support known or conventional operating characteristics that do not need to be described in detail herein. In one illustrative implementation, system 200 can be used in, for example... Figure 1 In a wireless communication environment such as 100, data symbols are transmitted (e.g., sent and received), as described above.

[0030] System 200 typically includes a base station 202 (hereinafter referred to as "BS 202") and a user equipment unit 204 (hereinafter referred to as "UE 204"). BS 202 includes a BS (Base Station) transceiver module 210, a BS antenna 212, a BS processor module 214, a BS memory module 216, and a network communication module 218, each module being coupled and interconnected with each other as needed via a data communication bus 220. UE 204 includes a UE (User Equipment) transceiver module 230, a UE antenna 232, a UE memory module 234, and a UE processor module 236, each module being coupled and interconnected with each other as needed via a data communication bus 240. BS 202 communicates with UE 204 via a communication channel 250, which can be any wireless channel or other medium suitable for data transmission as described herein.

[0031] As will be understood by those skilled in the art, system 200 may also include, in addition to Figure 2 Any number of modules other than those shown. Those skilled in the art will understand that the various illustrative blocks, modules, circuits, and processing logic described in conjunction with the embodiments disclosed herein can be implemented in hardware, computer-readable software, firmware, or any practical combination thereof. To clearly illustrate this interchangeability and compatibility of hardware, firmware, and software, various illustrative components, blocks, modules, circuits, and steps are typically described according to their functionality. Whether such functionality is implemented as hardware, firmware, or software may depend on the specific application and design constraints imposed on the system as a whole. Those skilled in the art can implement such functionality appropriately for each specific application, but such implementation decisions should not be construed as limiting the scope of the invention.

[0032] According to some implementations, UE transceiver 230 may be referred to herein as "uplink" transceiver 230, which includes a radio frequency (RF) transmitter and an RF receiver, each including circuitry coupled to antenna 232. A duplex switch (not shown) may optionally couple the uplink transmitter or receiver to the uplink antenna in a time-duplex manner. Similarly, according to some implementations, BS transceiver 210 may be referred to herein as "downlink" transceiver 210, which includes an RF transmitter and an RF receiver, each including circuitry coupled to antenna 212. A downlink duplex switch may optionally couple the downlink transmitter or receiver to downlink antenna 212 in a time-duplex manner. The operation of the two transceiver modules 210 and 230 can be coordinated in time such that the uplink receiver circuitry is coupled to the uplink antenna 232 for receiving transmissions on the radio transmission link 250 while the downlink transmitter is coupled to the downlink antenna 212. In some implementations, there is tight time synchronization with a minimum guard time between changes in duplex direction.

[0033] UE transceiver 230 and base transceiver 210 are configured to communicate via wireless data communication link 250 and cooperate with appropriately configured RF antenna devices 212 / 232, which may support specific wireless communication protocols and modulation schemes. In some illustrative implementations, UE transceiver 210 and base transceiver 210 are configured to support industry standards such as Long Term Evolution (LTE) and emerging 5G standards. However, it should be understood that the application of this disclosure is not limited to specific standards and related protocols. Rather, UE transceiver 230 and base transceiver 210 may be configured to support alternative or additional wireless data communication protocols, including future standards or variations thereof.

[0034] Depending on the implementation, BS 202 may be, for example, an evolved Node B (eNB), a serving eNB, a target eNB, a femtocell, or a picocell. In some implementations, UE 204 may be implemented in various types of user equipment, such as mobile phones, smartphones, personal digital assistants (PDAs), tablet computers, laptop computers, wearable computing devices, etc. Processor modules 214 and 236 may be implemented or implemented using general-purpose processors, content-addressable memory, digital signal processors, application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), any suitable programmable logic devices, discrete gate or transistor logic, discrete hardware components, or any combination thereof, designed to perform the functions described herein. In this way, the processor may be implemented as a microprocessor, a controller, a microcontroller, a state machine, etc. The processor may also be implemented as a combination of computing devices, such as a combination of a digital signal processor and a microprocessor, a combination of multiple microprocessors, a combination of one or more microprocessors and a digital signal processor core, or any other such configuration.

[0035] Furthermore, the steps of the methods or algorithms described in conjunction with the embodiments disclosed herein can be directly embodied in hardware, firmware, software modules executed by processor modules 214 and 236 respectively, or any actual combination thereof. Memory modules 216 and 234 can be implemented as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disk, removable disk, CD-ROM, or any other form of storage medium known in the art. In this respect, memory modules 216 and 234 can be coupled to processor modules 210 and 230 respectively, such that processor modules 210 and 230 can read information from and write information to memory modules 216 and 234 respectively. Memory modules 216 and 234 can also be integrated into their respective processor modules 210 and 230. In some implementations, memory modules 216 and 234 may each include a cache memory for storing temporary variables or other intermediate information during the execution of instructions to be executed by processor modules 210 and 230 respectively. Memory modules 216 and 234 may each include non-volatile memory for storing instructions executed by processor modules 210 and 230, respectively.

[0036] Network communication module 218 typically represents hardware, software, firmware, processing logic, and / or other components of base station 202 that enable bidirectional communication between base transceiver 210 and other network components and communication nodes configured to communicate with base station 202. For example, network communication module 218 may be configured to support Internet or WiMAX services. In a typical deployment, but not limited to, network communication module 218 provides an 802.3 Ethernet interface, enabling base transceiver 210 to communicate with conventional Ethernet-based computer networks. In this way, network communication module 218 may include a physical interface for connecting to a computer network (e.g., a mobile switching center (MSC)). The terms “configured for,” “configured to,” and variations thereof, as used herein with respect to a specified operation or function, refer to means, in the form of means, apparatus, components, circuits, structures, machines, signals, etc., physically constructed, programmed, formatted, and / or arranged to perform the specified operation or function.

[0037] Figure 3 This illustration shows a first determined wireless communication device, according to some implementations of this disclosure, in which the execution of second downlink control information is a repetition of first downlink control information. For example... Figure 3As shown in the example, the example wireless communication 300 extends in the x-axis time direction and the y-axis frequency direction, and includes CSS1 302 arranged in the first monitoring time 310, the second monitoring time 320, and the third monitoring time 330. In some implementations, CSS1 302 includes downlink control information 312, 322, 324, and 332.

[0038] In some implementations, the wireless communication device adds a new field to the DCI format using CRC scrambling by at least one of the following: INT-RNTI, SFI-RNTI, TPC-PUSCH-RNTI, TPC-PUCCH-RNTI, TPC-SRS-RNTI, CI-RNTI, and PS-RNTI. Therefore, in some implementations, the wireless communication device adds new fields to common DCI formats 2-1, 2-2, 2-3, 2-4, or 2-6. In some implementations, the new field is applied to each UE. In some implementations, each code point in the field contains an index X. In some implementations, X is an integer, X≥0. In some implementations, if X is not configured, the UE assumes that the UE's DCI is not duplicated.

[0039] In some implementations, the UE monitors the PDCCH. Furthermore, in some implementations, if public DCIs received within a predefined time period have the same format and contain the same index value X in the new field, the UE assumes these DCIs are duplicates. In response, in some implementations, the UE discards a duplicate DCI. As an example, the UE may accept the former and discard the latter. In some implementations, the aforementioned predefined time period is defined as N symbols or N time slots in at least one of the RRC parameter search space or control resource set. Alternatively, in some implementations of DCI formats 2-2 and 2-3, the predefined time period is the period during which TPC commands for the latest PUSCH, PUCCH, or SRS are accumulated. As an example, if DCI 312 and DCI 322 contain the same value 1 in the new field, the UE assumes that DCI 312 and DCI 322 are duplicate DCIs. Therefore, in this example, the UE accumulates TPC commands only in DCI 312, DCI 324 and DCI 332 for the latest PUSCH, and ignores DCI 322.

[0040] Figure 4 This illustration shows a second, determined wireless communication device, according to some implementations of this disclosure, in which the execution of second downlink control information is a repetition of first downlink control information. For example... Figure 4As shown in the example, the example wireless communication 400 extends in the x-axis time direction and the y-axis frequency direction, and includes a CSS1402 arranged in a first monitoring time 410, a second monitoring time 420, a third monitoring time 430, a fourth monitoring time 440, and a fifth monitoring time 450. In some implementations, the CSS1 402 includes downlink control information 412, 422, 432, 442, and 452.

[0041] In some implementations, the wireless communication device adds a new field to a DCI format that is CRC scrambled by at least one of the following: INT-RNTI, SFI-RNTI, TPC-PUSCH-RNTI, TPC-PUCCH-RNTI, TPC-SRS-RNTI, CI-RNTI, and PS-RNTI. In some implementations, the wireless communication device adds a new field to common DCI formats 2-1, 2-2, 2-3, 2-4, or 2-6. In some implementations, each code point in the field contains an index X. In some implementations, X is equal to 0 or 1. In some implementations, the gNB configures a repeating common DCI format with the same index X and transmits them continuously. In some implementations, continuous transmission is the transmission of two adjacent DCIs with the same format, without any other DCIs with other formats transmitted by the BS or received by the UE in between. In some implementations, if the UE receives multiple consecutive DCIs with the same DCI format within a predefined time period with the same index X, the UE assumes these DCIs are repeating DCIs. As an example, a single common DCI format exists within a predefined time period, and the indices X of two consecutive DCIs with the same DCI format are reversed. In this example, the UE assumes that a new transmission has been received when the X value changes from 0 to 1 or from 1 to 0. As another example, two consecutive DCIs 412 and 422 have the same DCI format 2-2 as DCIs 432 and 442. Furthermore, in this example, DCIs 432 and 442 have the same index 0, and the UE assumes that DCIs 432 and 442 are repeated. Therefore, in this example, the UE takes the TPC command in DCI 432 and ignores the TPC command in DCI 442.

[0042] Figure 5 A wireless communication device according to some implementations of this disclosure is shown, which realizes a first relationship between corresponding SS sets based on a first monitoring period. For example... Figure 5As shown in the example, the example wireless communication 500 extends in the x-axis time direction and the y-axis frequency direction, and includes CSS1 510 and CSS2 520. In some implementations, CSS1 510 is arranged in the first monitoring time period 502 at the first monitoring time point 512 and the second monitoring time point 514. In some implementations, CSS1 510 is arranged in the third monitoring time point 532 and the fourth monitoring time point 534 in the second monitoring period 502. In some implementations, CSS2 520 is arranged in the first monitoring time point 522, the second monitoring time point 524, and the third monitoring time point 526 in the first monitoring time period 502. In some implementations, CSS2 520 is arranged in the fourth monitoring time point 542, the fifth monitoring time point 544, and the sixth monitoring time point 546 in the second monitoring period 502.

[0043] In some implementations, the wireless communication device establishes at least one association between multiple SS sets. In some implementations, multiple monitoring opportunities are associated within multiple SS sets 510 and 520. In some implementations, SS sets 510 and 520 are CSS sets or USS sets. In some implementations, a bitmap is configured in the RRC signaling. In some implementations, the bitmap contains X bits, where X equals the number of monitoring opportunities in a monitoring period of the first SS set 510 multiplied by the number of monitoring opportunities in a monitoring period of the second SS set 520. In some implementations, each bit represents a combination of two monitoring opportunities from two SS sets in a monitoring period. In some implementations, if the bit value is 1, the two corresponding monitoring opportunities are associated. Similarly, in some implementations, if the bit value is 0, the two corresponding monitoring opportunities are not associated. In some implementations, the aforementioned RRC signaling is associated with at least one of SS sets 510 and 520 and a new RRC parameter. In some implementations, if a bitmap is configured in one of the SS sets, the SS set ID of the other SS set is also configured. In some implementations, the UE expects the same monitoring period 502 for the two SS sets 510 and 520.

[0044] In some implementations, if two DCIs are blindly detected in two associated monitoring events, the UE assumes that the two DCIs are duplicates. In other implementations, the UE assumes that the DCIs are duplicates based on one or more conditions. Under the first condition, the two DCIs have the same DCI format. Under the second condition, the two DCIs are common DCIs with the same DCI format and the same payload. Under the third condition, the two DCIs are UE-specified DCIs with the same DCI format and are scheduled on the same PDSCH / PUSCH. In some implementations, if one or more DCIs are duplicates, the UE may discard one duplicate DCI. As an example, the UE may ignore a DCI received later.

[0045] In some implementations, the wireless communication device establishes at least one relationship between multiple SS sets. In some implementations, multiple monitoring opportunities are associated within multiple SS sets 510 and 520. In some implementations, SS sets 510 and 520 are CSS sets or USS sets. In some implementations, the gNB configures the relationship between SS sets 510 and 520 and a time offset T. In some implementations, T is an integer and T ≥ 0. In some implementations, the time offset T can be T symbols, T time slots, or T monitoring opportunities, etc. It should be understood that the time offset is optional, and if no time offset T is configured, the UE assumes that T is 0. In the first offset configuration, in the RRC parameter search space, the ID of the SS set with the smallest index and the time offset T are configured in the SS set with the largest index. In the second offset configuration, the new RRC parameters include the IDs of the two associated SS sets and the time offset T.

[0046] In some implementations, the UE expects multiple SS sets 510 and 520 to have the same monitoring period 502. In some implementations, for each monitoring period 502, multiple associated PDCCH monitoring opportunities exist in two SS sets 510 and 520. In some implementations, if the time offset T is T MO, then the associated MO index in the calculated maximum index SS set is equal to the same MO index in the minimum index SS set + T. In some implementations, if the time offset is T symbols or T time slots, then the time position of the associated MO in the calculated maximum index SS set is equal to the time position of the MO in the minimum index SS set + T. Therefore, in some implementations, the time positions of the calculated associated monitoring opportunities do not cross the boundaries of the monitoring period.

[0047] In some implementations, example wireless communication 500 does not include the actually configured monitoring timing at the calculated time position of the associated monitoring timing. Furthermore, in some implementations, the calculated associated MO index is not included in the SS set with the largest index. Therefore, in some implementations, the UE assumes the most recent actual monitoring timing is the associated PDCCH monitoring timing. In some implementations, the most recent actual monitoring timing is a predetermined monitoring position. A first predetermined monitoring timing is after the calculated time position of the associated monitoring timing in the corresponding SS set 510 or 520, and is closest to it within a monitoring period. A second predetermined monitoring timing is before the calculated time position of the associated monitoring timing in the corresponding SS set, and is closest to it within a monitoring period. In some implementations, a monitoring timing in the SS set with the largest index can only be associated with one monitoring timing in the SS set with the smallest index. In some implementations, one monitoring timing in the SS set with the largest index can be associated with at most N monitoring timings in the SS set with the smallest index. In some implementations, N is an integer. For example, N equals 2. In some implementations, MOs with smaller indices in the SS set with the smallest index have higher priority than MOs with larger indices so that they can be associated with other MOs.

[0048] In some implementations, if two DCIs are blindly detected in two associated monitoring moments, the UE assumes that the two DCIs are duplicated based on one or more conditions. Under the first condition, the two DCIs have the same DCI format. Under the second condition, the two DCIs are common DCIs, have the same DCI format, and the same payload. Under the third condition, the two DCIs are UE-specified DCIs, have the same DCI format, and are scheduled on the same PDSCH / PUSCH. In some implementations, if one or more DCIs are duplicated, the UE may discard one duplicated DCI. As an example, the UE may ignore a DCI received later. As an example, the time offset is configured for one monitoring moment, so MO1 512 and 532 and MO2 514 and 534 in SS1 510 are associated with MO2 524 and 544 and MO3 526 and 546 in SS2 520 respectively through associations 552, 554, 562, and 564 within the same monitoring period.

[0049] Figure 6 A wireless communication device according to some implementations of this disclosure is shown, which realizes at least one relationship between corresponding SS sets based on a first monitoring period and a second monitoring period. For example... Figure 5As shown in the example, the example wireless communication 500 extends in the x-axis time direction and the y-axis frequency direction, and includes CSS1 510 and CSS2 520. In some implementations, CSS1 610 is arranged in the first monitoring timing 612, the second monitoring timing 614, and the third monitoring timing 616 within the first monitoring period 602. In some implementations, CSS2 620 is arranged in the first monitoring timing 622 and the second monitoring timing 624 within the second monitoring period 604. In some implementations, CSS1 520 includes a time offset T 606 and a detection window 640.

[0050] In some implementations, the wireless communication device establishes relationships between multiple SS sets. In some implementations, multiple monitoring opportunities are associated within these multiple SS sets. In some implementations, SS sets 610 and 620 are CSS sets or USS sets. In some implementations, the gNB configures relationships between multiple SS sets and one or more of time offsets T 606. In some implementations, T is an integer and T ≥ 0. In some implementations, the time offset T 606 can be T symbols, T time slots, or T monitoring opportunities. In some implementations, the wireless communication device defines a detection window 640. In some implementations, the duration of the detection window 640 is the monitoring period of the largest-indexed SS set or the smallest-indexed SS set. In some implementations, the configuration in the RRC signaling can be configured according to one or more configurations. In a first offset configuration, in the RRC parameter search space, the ID and time offset T of the smallest-indexed SS set are configured within the larger-indexed SS set. In a second offset configuration, the new RRC parameters include the associated two SS set IDs and time offset T.

[0051] In some implementations, multiple associated PDCCH monitoring opportunities reside in multiple SS sets. In some implementations, a one-to-one monitoring opportunity in the minimum index SS set is associated with a monitoring opportunity in the detection window 640 of the maximum index SS set. In some implementations, the start time of the detection window 640 is the time position of the first monitoring opportunity or the first sign of the monitoring period in the minimum index SS set plus the configured time offset T 606.

[0052] In some implementations, one monitoring opportunity from the SS set of the largest index can only be associated with one monitoring opportunity from the SS set of the smallest index. In some implementations, one monitoring opportunity from the SS set of the largest index is associated with at most N monitoring opportunities from the SS set of the smallest index. In some implementations, N is an integer. For example, N equals 2. In some implementations, the MO of a smaller index has a higher priority than the MO of a larger index for association with the MO.

[0053] In some implementations, if two DCIs are blindly detected in two associated monitoring events, the UE assumes that the two DCIs are duplicated. In some implementations, the UE assumes that a DCI is duplicated based on one or more conditions. Under the first condition, the two DCIs have the same DCI format. Under the second condition, the two DCIs are common DCIs with the same DCI format and the same payload. Under the third condition, the two DCIs are UE-specified DCIs, have the same DCI format, and are scheduled on the same PDSCH / PUSCH, SRS, or CSI report, etc. In some implementations, if one or more DCIs are duplicated, the UE can discard one duplicated DCI. As an example, the UE can ignore a DCI received later.

[0054] Figure 7 A wireless communication device according to some implementations of this disclosure is shown, which realizes a second relationship between corresponding SS sets based on a first monitoring period. For example... Figure 7 As shown in the example, the example wireless communication 700 extends in the x-axis time direction and the y-axis frequency direction, and includes CSS1 710 and CSS2 720. In some implementations, CSS1 710 is arranged in the first monitoring time period 702 at the first monitoring time point 712 and the second monitoring time point 714. In some implementations, CSS1 710 is arranged in the third monitoring time point 732 and the fourth monitoring time point 734 in the second monitoring period 702. In some implementations, CSS2 720 is arranged in the first monitoring time point 722, the second monitoring time point 724, and the third monitoring time point 726 in the first monitoring time period 702. In some implementations, CSS2 720 is arranged in the fourth monitoring time point 742, the fifth monitoring time point 744, and the sixth monitoring time point 776 in the second monitoring period 702.

[0055] In some implementations, the wireless communication device implements at least one association 752, 754, 762, and 764 between multiple SS sets 510 and 520. In some implementations, multiple monitoring opportunities are associated within these multiple SS sets. In some implementations, the two SS sets 510 and 520 have the same monitoring period. Therefore, in some implementations, the first X monitoring opportunities in the two SS sets are associated on a one-to-one basis. In some implementations, X is an integer and X ≥ 0. In some implementations, the value of X cannot be greater than the minimum number of monitoring opportunities in at least one SS set. In some implementations, the configuration in the RRC signaling can be configured according to one or more configurations. In a first signaling configuration, in the RRC parameter search space, the ID of the smaller index SS set and the number X of associated monitoring opportunities in the larger index SS set are configured in the larger index SS set. In a second signaling configuration, the new RRC parameters include the related two SS set IDs, the time offset T, and the number X of associated monitoring opportunities. In some implementations, X is not configured or X = 0, and the wireless communication device does not generate a correlation between the monitoring opportunities in the two SS sets 510 and 520.

[0056] In some implementations, if two DCIs are blindly detected in two associated monitoring events, the UE assumes that the two DCIs are duplicated. In some implementations, the UE assumes that a DCI is duplicated based on one or more conditions. Under the first condition, the two DCIs have the same DCI format. Under the second condition, the two DCIs are common DCIs with the same DCI format and the same payload. Under the third condition, the two DCIs are UE-specified DCIs with the same DCI format and are scheduled on the same PDSCH / PUSCH, or SRS, or CSI report, etc. In some implementations, if one or more DCIs are duplicated, the UE may discard one duplicated DCI. As an example, the UE may ignore a DCI received later.

[0057] Figure 8 Example methods according to some implementations of this disclosure are shown. In some implementations, at least one of BS 202 and UE 201 performs method 800 according to this implementation. In some implementations, method 800 begins at 810.

[0058] At 810, the example system receives first and second control information from BS 202 at UE 201. In some implementations, 810 includes at least one of 812, 814, and 816. At 812, the example system receives first control information in a first format. At 814, the example system receives second control information in a second format. At 816, the example system continuously receives the first and second control information. Method 800 then continues to 820.

[0059] At 820, the example system determines at UE 201 that the second control information is a repetition of the first control information. In some implementations, 820 includes 822. At 822, the first control information is determined based on a first format of the first control information and a second format of the second control information. Then method 800 continues to 830.

[0060] At 830, the example system determines at UE 201 whether the first control information and the second control information were received within a predefined time period. In some implementations, the predefined time period corresponds to detection window 640. Based on the determination that the first control information and the second control information were received within the predefined time period, method 800 continues to 840. Alternatively, based on the determination that the first control information and the second control information were not received within the predefined time period, method 800 continues to 860. At 860, method 800 continues to 810.

[0061] At 840, the example system determines at UE 201 whether the first control information and the second control information are the same. In some implementations, 840 includes 842 and 844. At 842, the example system determines that the first format and the second format are the same. At 844, the example system determines that the first index and the second index are the same. In some implementations, method 800 continues to 850.

[0062] Figure 9 Example methods according to some implementations of this disclosure are shown. In some implementations, at least one of BS 202 and UE 201 performs method 900 according to this implementation. In some implementations, method 900 begins at 850. At 850, method 900 continues to 910.

[0063] At 910, the example system determines at UE 201 whether the first control information was received during the first monitoring time. If it is determined that the first control information was received during the first monitoring time, method 900 continues to 912. Alternatively, if it is determined that the first control information was not received during the first monitoring time, method 900 continues to 860. At 912, the example system determines at UE 201 whether the second control information was received during the second monitoring time. If it is determined that the second control information was received during the second monitoring time, method 900 continues to 914. Alternatively, if it is determined that the second control information was not received during the second monitoring time, method 900 continues to 860. At 914, the example system determines at UE 201 whether the first monitoring time and the second monitoring time are in different SS sets. If it is determined that the first monitoring time and the second monitoring time are in different SS sets, method 900 continues to 920. Alternatively, if it is determined that the first monitoring time and the second monitoring time are not in different SS sets, method 900 continues to 860.

[0064] At 920, the example system determines at UE 201 whether the first control information is a duplicate of the second control information. In some implementations, 920 includes at least one of 922, 924, and 926. At 922, the example system determines that the first format and the second format are the same. At 924, the example system determines that the first control information and the second control information include the same payload. At 926, the example system determines that the first control information and the second control information are scheduled on the same resource. Method 900 then proceeds to step 930.

[0065] In step 930, the example system determines at least one time position of a first monitoring opportunity at UE 201. In some implementations, 930 includes at least one of 932 and 934. At 932, the example system determines the time position at least partially based on a time offset. In some implementations, the time offset corresponds to time offset 606. At 934, the example system determines the time position at least partially based on the time position of a second monitoring opportunity. In some implementations, method 900 ends at 930.

[0066] Figure 10 Another example method according to some implementations of this disclosure is shown. In some implementations, at least one of BS202 and UE 201 performs method 1000 according to this implementation. In some implementations, method 1000 begins at 1010.

[0067] At 1010, the example system receives first and second control information from BS 202 at UE 201. Method 1000 then proceeds to 1020. At 1020, the example system determines at UE 201 that the second control information is a repetition of the first control information. Method 1000 then proceeds to 1030.

[0068] At 1030, the example system determines at UE 201 whether the first control information and the second control information were received within a predefined time period. In some implementations, the predefined time period corresponds to detection window 640. If it is determined that the first control information and the second control information were received within the predefined time period, method 1000 continues to 1040. Alternatively, if it is determined that the first control information and the second control information were not received within the predefined time period, method 1000 continues to 1010.

[0069] At step 1040, the example system determines at UE 201 whether the first control information and the second control information are the same. Method 1000 continues to step 1050. At 1050, the example system determines at UE 201 whether the first control information is a duplicate of the second control information. Method 1000 then continues to step 1060. In step 1060, the example system determines at least one time position of the first monitoring opportunity at UE 201. In some implementations, method 1000 ends at step 1060.
