Typically, entity downlink control channel (PDCCH) candidates in a first search space (SS) set and a second SS set can reside in the same time slot. When two SS sets have the same period and the same offset, the UE can determine that the SS sets are linked. The UE can anticipate the same number of monitoring opportunities for each SS set within the time slot, and can determine that monitoring opportunities with a first index value in the first SS set are linked to monitoring opportunities with the same index value in the second SS set. The UE can determine that monitoring opportunities for different SS sets with the same period but different offsets reside in different time slots, and satisfy a rule such that the first PDCCH repetition resides in a time slot earlier than the second PDCCH repetition.

[0002] The following text pertains to wireless communications, including the monitoring of search space sets for repeated physical downlink control channels. Prior Technology

[0003] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, and broadcasting. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiplexing access systems include fourth-generation (4G) systems (such as Long Term Evolution (LTE), Advanced LTE (LTE-A), or LTE-A Pro systems) and fifth-generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems may employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiple Access (DFT-S-OFDM). Wireless multiplexing access communication systems may include one or more base stations or one or more network access nodes, each base station or network access node simultaneously supporting communication with multiple communication devices (which may also be referred to as User Equipment (UE)). In some instances, the UE can support physical downlink control channel (PDCCH) repetition. Summary of the Invention

[0004] The described technology relates to improved methods, systems, devices, and apparatuses for monitoring repeated search space (SS) sets for physical downlink control channels (PDCCH). Typically, when different SS sets are in the same or different time slots, a user equipment (UE) can determine whether the monitoring timing of a first SS set is linked to the monitoring timing of a second SS set. For example, the UE can determine that PDCCH candidates in the first and second SS sets are in the same time slot based on a monitoring pattern for the SS sets configured by the base station. When two SS sets have the same period and the same offset, the UE can determine that SS sets located in the same time slot are linked. In some instances, the duration of the monitoring pattern may also be the same. In some instances, the UE may anticipate the same number of monitoring timings for each SS set within the time slot (e.g., the Radio Resource Control (RRC) parameter monitoring symbolsWithinSlot may be the same for each SS set). The UE can determine that each SS set has the same number of monitoring timings, and that monitoring timings with a first index value in the first SS set are linked to monitoring timings with the same index value in the second SS set.

[0005] In some instances, the UE can determine, based on instructions from the base station, that the monitoring timing for different SS sets is located in different time slots, where the two SS sets have the same period but different offsets. The UE can decide to satisfy one or more rules such that the first PDCCH repetition in the first SS set is always located in a time slot earlier than the second PDDCH repetition in the second SS set.

[0043] Some wireless communication systems can support physical downlink control channel (PDCCH) monitoring and PDCCH repetition across different search space (SS) sets. User equipment (UE) can be configured with PDCCH repetition. In this example, a base station can transmit control information multiple times across multiple repetitions. PDCCH candidates in a first SS set can be linked to PDCCH candidates in a second SS set. The UE can perform a soft combination procedure by combining control signal transmissions received in the first PDCCH candidate set of the first SS set with control signal transmissions received in the second SS set. Therefore, the UE can monitor a first PDCCH candidate set (e.g., in the first SS set), a second PDCCH candidate set (e.g., in the second SS set), and a third PDCCH candidate set (e.g., by combining the first and second PDCCH candidate sets). Each SS set can be defined according to the monitoring slot period and offset, as well as other parameters (e.g., duration, number of monitoring opportunities, etc.). Therefore, the monitoring timings of the SS set can be distributed across time slots in inter-slot PDCCH repetition scenarios, across individual symbols of time slots in intra-slot PDCCH repetition scenarios, or both. The UE can benefit from knowing how to determine which monitoring timings of the first SS set are associated with which monitoring timings of the second SS set in order to successfully monitor associated PDCCH candidates and combine repetitions of control signals.

[0044] This technique is used to determine whether the monitoring timing of a first SS set is linked to the monitoring timing of a second SS set when different SS sets are in the same or different time slots. For example, the UE can determine that PDCCH candidates in the first and second SS sets are in the same time slot based on a monitoring mode configured for the SS sets, such as by RRC parameters (e.g., monitoringSlotPeriodicityAndOffset parameters). When two SS sets have the same period and the same offset, the UE can determine that SS sets in the same time slot are linked. In some instances, the duration of the monitoring mode can also be the same. In such instances, the UE may anticipate the same number of monitoring timings for each SS set within the time slot (e.g., the RRC parameter monitoring symbolsWithinSlot can be the same for each SS set). The UE can determine that each SS set has the same number of monitoring timings, and that monitoring timings with a first index value in the first SS set are linked to monitoring timings with the same index value in the second SS set.

[0045] In some instances, the UE can determine the location of monitoring events for different SS sets in different time slots based on the monitoring mode (e.g., configured for each SS set via RRC parameters such as monitoringSlotPeriodicityAndOffset), where the two SS sets have the same period but different offsets. The UE can determine to satisfy one or more rules such that the first PDCCH repetition in the first SS set always resides in a time slot earlier than the second PDDCH repetition in the second SS set. In such an instance, the UE can determine to link monitoring events with a first index value in the first SS set with monitoring events with the same index value in the second SS set.

[0046] The various forms of this disclosure are first described in the context of a wireless communication system and an isochronous line. These forms are further illustrated by apparatus diagrams, system diagrams, and flowcharts relating to the monitoring of SS sets for PDCCH repetition, and described with reference to apparatus diagrams, system diagrams, and flowcharts relating to the monitoring of SS sets for PDCCH repetition.

[0047] Figure 1 illustrates examples of various types of wireless communication systems 100 supporting SS set monitoring for PDCCH repetition according to this disclosure. Wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some instances, wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some instances, wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, communication with low-cost and low-complexity devices, or any combination thereof.

[0048] Base stations 105 can be distributed across a geographical area to form a wireless communication system 100, and can be devices of different forms or with different capabilities. Base stations 105 and UE 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110, on which UE 115 and base station 105 can establish one or more communication links 125. Coverage area 110 can be an example of a geographical area where base stations 105 and UE 115 can support signal transmission according to one or more radio access technologies.

[0049] UE 115 may be distributed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary, active, or both at different times. UE 115 may be devices in different forms or with different capabilities. Some example UE 115s are shown in Figure 1. The UE 115 described herein may be able to communicate with various types of devices, such as other UE 115s, base stations 105, or network devices (e.g., core network nodes, relay devices, integrated access and backload (IAB) nodes, or other network devices), as shown in Figure 1.

[0050] Base station 105 can communicate with core network 130, or communicate with each other, or both. For example, base station 105 can interface with core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base stations 105 can communicate with each other directly (e.g., directly between base stations 105), or indirectly (e.g., via core network 130), or both, on backhaul links 120 (e.g., via X2, Xn, or other interfaces). In some instances, backhaul link 120 can be one or more radio links or include one or more radio links.

[0051] One or more of the base stations 105 described herein may include, or may be referred to by those skilled in the art as, base station transceiver, radio base station, access point, radio transceiver, node B, evolved node B (eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), home node B, home evolved node B, or other suitable terms.

[0052] UE 115 may include or may be referred to as mobile device, wireless device, remote device, handheld device, or user equipment, or some other suitable term, wherein "device" may also be referred to as cell, station, terminal, or client, and other instances. UE 115 may also include or be referred to as personal electronic devices, such as cellular phones, personal digital assistants (PDAs), multimedia / entertainment devices (e.g., radio units, MP3 players, or video equipment), cameras, gaming devices, navigation / positioning devices (e.g., GNSS (Global Navigation Satellite System) devices based on, for example, GPS (Global Positioning System), BeiDou, GLONASS, or Galileo, or terrestrial devices), tablets, laptops, personal computers, netbooks, smart computers, personal computers, smart devices, wearable devices (e.g., smartwatches, smart clothing, smart glasses, virtual reality glasses, smart wristbands, smart jewelry (e.g., smart rings, smart bracelets)), drones, robot / robot devices, vehicles, in-vehicle equipment, meters (e.g., parking timers, electricity meters, gas meters, water meters), monitors, air pumps, electrical appliances (e.g., kitchen appliances, washing machines, dryers), location markers, medical / healthcare devices, implants, sensors / actuators, displays, or any other suitable device configured to communicate via wireless or wired media. In some instances, UE 115 may include, or be referred to as, a Wireless Area Loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a Machine Type Communication (MTC) device, as well as other instances, which may be implemented in various items such as appliances, vehicles, meters, and other instances.

[0053] The UE 115 described herein may be able to communicate with various types of devices, such as other UE 115s that may sometimes act as repeaters, as well as base stations 105 and network devices (including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations and other examples), as shown in Figure 1.

[0054] UE 115 and base station 105 can communicate wirelessly with each other via one or more communication links 125 on one or more carriers. The term "carrier" can refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting communication links 125. For example, a carrier for communication link 125 may include a portion of a radio spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signal transmissions (e.g., synchronization signals, system information), control signal transmissions coordinating operation for the carrier, user data, or other signal transmissions. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. UE 115 can be configured to have multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers.

[0055] In some instances (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signal passing or control signal passing that coordinates operation against other carriers. A carrier may be associated with a frequency channel (e.g., an Evolutionary Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be located based on a channel grid for discovery by the UE 115. A carrier may operate in standalone mode, where initial acquisition and connection can be performed by the UE 115 via that carrier, or the carrier may operate in non-standalone mode, where connection is anchored using different carriers (e.g., the same or different radio access technologies).

[0056] The communication link 125 illustrated in the wireless communication system 100 may include uplink transmission from UE 115 to base station 105, or downlink transmission from base station 105 to UE 115. The carrier may carry downlink or uplink communication (e.g., in FDD mode) or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).

[0057] A carrier can be associated with a specific bandwidth of the radio frequency spectrum, and in some instances, the carrier bandwidth can be referred to as the carrier or the "system bandwidth" of the wireless communication system 100. For example, the carrier bandwidth can be one of several determined bandwidths (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz) for a particular radio access technology. The equipment of the wireless communication system 100 (e.g., base station 105, UE 115, or both) can have hardware configurations supporting communication on a specific carrier bandwidth, or can be configured to support communication on one carrier bandwidth in a set of carrier bandwidths. In some instances, the wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some instances, each served UE 115 can be configured to operate on a portion (e.g., a subband, BWP) or all of the carrier bandwidth.

[0058] The signal waveform transmitted on a carrier can consist of multiple subcarriers (e.g., using multicarrier modulation (MCM) techniques such as Orthogonal Frequency Division Multiplexing (OFDM) or Discrete Fourier Transform Spread Spectrum OFDM (DFT-S-OFDM). In a system employing MCM, a resource element can include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements UE 115 receives and the higher the order of the modulation scheme, the higher the data rate can be for UE 115. Radio communication resources can refer to a combination of radio frequency spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further increase the data rate or data integrity for communication with UE 115.

[0059] It can support one or more numerologies for a carrier, where the numerology can include a subcarrier spacing (∆f) and a cyclic prefix. A carrier can be divided into one or more BWPs with the same or different numerologies. In some instances, UE 115 can be configured to have multiple BWPs. In some instances, a single BWP for a carrier can be active at a given time, and communication for UE 115 can be restricted to one or more active BWPs.

[0060] The time interval for base station 105 or UE 115 can be in multiples of basic time units (which can, for example, refer to...). The sampling period is seconds, in which This can represent the maximum supported subcarrier spacing, and This can be expressed as the size of the maximum supported Discrete Fourier Transform (DFT). The time interval of the communication resource can be organized according to radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0061] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some instances, a frame may (e.g., in the time domain) be divided into subframes, and each subframe may be further divided into multiple time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier interval. Each time slot may include multiple symbol periods (e.g., depending on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple microtime slots containing one or more symbols. In addition to the cyclic prefix, each symbol period may contain one or more (e.g., (Number) sampling periods. The duration of a symbol period can depend on the subcarrier interval or the operating frequency band.

[0062] Subframes, time slots, micro-time slots, or symbols can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain), and can be referred to as transmission time intervals (TTIs). In some instances, the duration of the TTI (e.g., the number of symbol periods in a TTI) can be variable. Alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in short pulses of shortened TTIs (sTTIs)).

[0063] Physical channels can be multiplexed on a carrier using various techniques. Physical control channels and physical data channels can be multiplexed on a downlink carrier, for example, using one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques. Control regions (e.g., control resource sets (CORESET)) used for physical control channels can be defined by multiple symbol periods and can extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESET) can be configured for a group of UEs 115. For example, one or more UEs in UE 115 can monitor or search for control regions for control information based on one or more SS sets, and each SS set can include one or more control channel candidates arranged in a cascaded manner at one or more aggregation levels. The aggregation level for control channel candidates can refer to the number of control channel resources (e.g., control channel elements (CCE)) associated with encoded information for a control information format having a given payload size. The SS set may include a common SS set configured to send control information to multiple UEs 115 and a UE-specific SS set configured to send control information to a specific UE 115.

[0064] Each base station 105 may provide communication coverage via one or more cells (e.g., macrocells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used (e.g., on a carrier) for communication with base station 105, and may be associated with an identifier used to distinguish adjacent cells (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or others). In some instances, a cell may also refer to a geographic coverage area 110 or a portion of geographic coverage area 110 (e.g., a sector) on which a logical communication entity operates. Depending on various factors (such as the capabilities of base station 105), such cells may range from small areas (e.g., structures, subsets of structures) to large areas. For example, a cell may be or include buildings, subsets of buildings, or external space between or overlapping geographic coverage areas 110, and other instances.

[0065] Macrocells typically cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access by UE 115 with a service subscription to a network provider supporting the macrocell. In contrast, small cells can be associated with a lower-power base station 105 and can operate in the same or different (e.g., licensed, unlicensed) frequency bands as macrocells. Small cells can provide unrestricted access to UE 115 with a service subscription to a network provider, or restricted access to UE 115 associated with a small cell (e.g., UE 115 in a Closed Subscriber Group (CSG), or UE 115 associated with a user in a residence or office). Base station 105 can support one or more cells and can also support communications using one or more component carriers over one or more cells.

[0066] In some instances, a carrier can support multiple cells, and different cells can be configured based on different protocol types that can provide access for different types of devices (e.g., MTC, Narrowband IoT (NB-IoT), Enhanced Mobile Broadband (eMBB)).

[0067] In some instances, base station 105 may be mobile, and therefore provide communication coverage for mobile geographic coverage areas 110. In some instances, different geographic coverage areas 110 associated with different technologies may overlap, but different geographic coverage areas 110 may be supported by the same base station 105. In other instances, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. Wireless communication system 100 may include, for example, a heterogeneous network in which different types of base stations 105 use the same or different radio access technologies to provide coverage for various geographic coverage areas 110.

[0068] The wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, base stations 105 can have similar frame timings, and transmissions from different base stations 105 can be approximately aligned in time. For asynchronous operation, base stations 105 can have different frame timings, and in some instances, transmissions from different base stations 105 can be misaligned in time. The techniques described herein can be used for both synchronous and asynchronous operation.

[0069] Some UEs 115 (such as MTC or IoT devices) can be low-cost or low-complexity devices, and can be prepared for automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with base station 105 without human intervention. In some instances, M2M communication or MTC can include communication from devices that integrate sensors or meters to measure or acquire information and relay such information to a central server or application that uses the information or presents it to humans interacting with the application. Some UEs 115 can be designed to collect information or automate the behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, climate and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business billing. In one instance, the techniques disclosed herein can be applied to MTC or IoT UEs. MTC or IoT UE can include MTC / enhanced MTC (eMTC, also known as CAT-M, Cat M1) UE, NB-IoT (also known as CAT NB1) UE, and other types of UE. eMTC and NB-IoT can refer to technologies that may evolve from or be based on these technologies in the future. For example, eMTC can include FeMTC (further eMTC), eFeMTC (enhanced further eMTC), and mMTC (massive MTC), and NB-IoT can include eNB-IoT (enhanced NB-IoT) and FeNB-IoT (further enhanced NB-IoT).

[0070] Some UE 115s can be configured to operate in reduced-power modes, such as half-duplex communication (e.g., a mode that supports unidirectional communication via either transmission or reception instead of simultaneous transmission and reception). In some instances, half-duplex communication may be performed at a reduced peak rate. Other power-saving techniques for UE 115 include: operating on a limited bandwidth (e.g., according to narrowband communication) when not engaged in active communication, entering a power-saving deep sleep mode, or a combination of these techniques. For example, some UE 115s can be configured to operate using a narrowband protocol type associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs) within a carrier, within a carrier's guard band, or outside the carrier.

[0071] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private or group communication, and can be supported by one or more mission-critical services (such as Mission-Critical Push-to-Talk (MCPTT), Mission-Critical Video (MCVideo), or Mission-Critical Data (MCData)). Support for mission-critical functions can include service prioritization, and mission-critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency are used interchangeably herein.

[0072] In some instances, UE 115 may also be able to communicate directly with other UE 115s on a device-to-device (D2D) communication link 135 (e.g., using peer-to-peer (P2P) or D2D protocols). One or more UE 115s utilizing D2D communication may be within the geographic coverage area 110 of base station 105. Other UE 115s in this group may be outside the geographic coverage area 110 of base station 105 or otherwise unable to receive transmissions from base station 105. In some instances, a group of UE 115s communicating via D2D communication may utilize a one-to-many (1:M) system, in which each UE 115 sends to every other UE 115 in the group. In some instances, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UE 115s without involving base station 105.

[0073] In some systems, the D2D communication link 135 may be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some instances, the vehicle may communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination thereof. The vehicle may signal information relating to traffic conditions, signal scheduling, weather, safety, emergencies, or any other information relating to the V2X system. In some instances, a vehicle in a V2X system may communicate with roadside infrastructure (such as roadside units), or communicate with the network via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communication, or communicate with both.

[0074] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an Evolved Packet Core (EPC) or a 5G Core (5GC), which may include at least one control plane entity (e.g., a Mobility Management Entity (MME), Access and Mobility Management Function (AMF)) managing access and mobility, and at least one user plane entity (e.g., a Serving Gateway (S-GW), Packet Data Network (PDN) Gateway (P-GW), or User Plane Function (UPF)) routing packets or interconnects to external networks. The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UE 115 served by base station 105 associated with core network 130. User IP packets may be transmitted via a user plane entity that can provide IP address allocation and other functions. The user plane entity may connect to IP services 150 for one or more network service providers. IP service 150 may include access to the Internet, intranet, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0075] Some network devices (such as base station 105) may include sub-components such as access network entity 140, which may be an instance of access node controller (ANC). Each access network entity 140 may communicate with UE 115 via one or more other access network transport entities 145 (which may be referred to as a radio headend, smart radio headend, or transmit / receive point (TRP)). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio headends and ANCs) or consolidated into a single network device (e.g., base station 105).

[0076] Wireless communication system 100 can operate using one or more frequency bands (typically in the range of 300 MHz to 300 GHz). The region from 300 MHz to 3 GHz is generally referred to as the Ultra High Frequency (UHF) region or decimeter band because the wavelength range extends from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, but the waves can be sufficiently permeable to the structure to provide service to the UE 115 located indoors. Transmission of UHF waves can be associated with smaller antennas and shorter ranges (e.g., less than 100 km) compared to the smaller frequencies and longer waves used in the lower 300 MHz portion of the spectrum in the High Frequency (HF) or Ultra High Frequency (VHF) regions.

[0077] The wireless communication system 100 can also operate in the extremely high frequency (SHF) region using a frequency band from 3 GHz to 30 GHz (also known as the centimeter band) or in the highest frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also known as the millimeter band). In some instances, the wireless communication system 100 can support millimeter-wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the corresponding device can be smaller and more closely spaced compared to UHF antennas. In some instances, this can facilitate the use of antenna arrays within the device. However, compared to SHF or UHF transmissions, EHF transmissions may suffer even greater atmospheric attenuation and shorter range. The techniques disclosed herein can be employed for transmissions using one or more different frequency regions, and the designated use of frequency bands spanning such frequency regions may vary depending on the country or regulatory authority.

[0078] Wireless communication system 100 can utilize both licensed and unlicensed radio spectrum bands. For example, wireless communication system 100 can employ Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology in unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating in unlicensed radio spectrum bands, devices (such as base station 105 and UE 115) can employ carrier sensing for collision detection and avoidance. In some instances, operation in unlicensed frequency bands can be based on carrier aggregation configurations that combine component carriers operating in licensed frequency bands (e.g., LAA). Operation in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other instances.

[0079] Base station 105 or UE 115 may be equipped with multiple antennas, which can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels (which may support MIMO operation or transmit or receive beamforming). For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some instances, the antennas or antenna arrays associated with base station 105 may be located in a variety of geographical locations. Base station 105 may have an antenna array with multiple rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Alternatively or additionally, antenna panels may support radio frequency beamforming for signals transmitted via antenna ports.

[0080] Base station 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals through different spatial layers. This technique can be called spatial multiplexing. Multiple signals can be transmitted, for example, by a transmitting device through different antennas or different combinations of antennas. Similarly, multiple signals can be received by a receiving device through different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry bits associated with the same data stream (e.g., the same coded characters) or different data streams (e.g., different coded characters). Different spatial layers can be associated with different antenna ports used for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO) (where multiple spatial layers are transmitted to the same receiving device) and multi-user MIMO (MU-MIMO) (where multiple spatial layers are transmitted to multiple devices).

[0081] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105, UE 115) to form or guide antenna beams (e.g., transmit beams, receive beams) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating relative to a specific orientation of the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to the signals transmitted via the antenna elements can include applying amplitude offset, phase offset, or both to the signals carried via the antenna elements associated with the device by the transmitting or receiving device. The adjustments associated with each antenna element can be defined by a set of beamforming weights associated with a specific orientation (e.g., relative to the antenna array of the transmitting or receiving device, or relative to some other orientation).

[0082] As part of beamforming operations, base station 105 or UE 115 may use beam scanning techniques. For example, base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by base station 105 in different directions. For example, base station 105 may transmit signals according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions may be used (e.g., by a transmitting device (such as base station 105) or by a receiving device (such as UE 115)) to identify the beam direction for subsequent transmissions or receptions performed by base station 105.

[0083] Some signals (such as data signals associated with a specific receiving device) may be transmitted by base station 105 in a single beam direction (e.g., the direction associated with that receiving device (such as UE 115)). In some instances, the beam direction associated with transmission along a single beam direction may be determined based on the signals transmitted in one or more beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions, and may report to base station 105 an indication of the signal received by UE 115 that has the highest signal quality or otherwise acceptable signal quality.

[0084] In some instances, transmissions performed by a device (e.g., by base station 105 or UE 115) may be executed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a combination of beams for transmissions (e.g., from base station 105 to UE 115). UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a number of beams configured across the system bandwidth or one or more sub-bands. Base station 105 may transmit reference signals (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)), which may or may not be precoded. UE 115 may provide feedback on beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel type codebook, linear combination type codebook, port selection type codebook). Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may employ similar techniques to transmit signals multiple times in different directions (e.g., to identify the beam direction for subsequent transmission or reception by UE 115) or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0085] When a receiving device (e.g., UE 115) receives various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105, it can try multiple receiving configurations (e.g., directional listening). For example, the receiving device can try multiple receiving directions by receiving via different antenna subarrays, by processing the received signals according to different antenna subarrays, by receiving according to different sets of receiving beamforming weights applied to the signals received at multiple antenna elements of the antenna array (e.g., different sets of directional listening weights), or by processing the received signals according to different sets of receiving beamforming weights applied to the signals received at multiple antenna elements of the antenna array (any of these operations can be referred to as "listening" according to different receiving configurations or receiving directions). In some instances, the receiving device can use a single receiving configuration to receive along a single beam direction (e.g., when receiving data signals). A single receiver configuration can be aligned to a beam direction determined based on listening in different receiver configuration directions (e.g., a beam direction determined based on listening in multiple beam directions to have the highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality).

[0086] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or packet data convergence protocol (PDCP) layer can be IP-based. The Radio Link Control (RLC) layer can perform packet fragmentation and reassembly for transmission over logical channels. The Media Access Control (MAC) layer can perform prioritization and multiplexing from logical channels to transport channels. The MAC layer can also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer to improve link efficiency. In the control plane, the RRC protocol layer can provide the establishment, configuration, and maintenance of RRC connections (which support radio bearers for user plane data) between the UE 115 and the base station 105 or core network 130. At the physical layer, transport channels can be mapped to physical channels.

[0087] UE 115 and base station 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique used to increase the likelihood of data being correctly received on communication link 125. HARQ can include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), forward error correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). HARQ can improve throughput at the MAC layer under poor radio conditions (e.g., low signal and noise conditions). In some instances, the equipment can support same-slot HARQ feedback, where the equipment can provide HARQ feedback for data received in a previous symbol within a specific time slot. In other cases, the equipment can provide HARQ feedback in subsequent time slots or according to some other time interval.

[0088] This technique is used to determine whether the monitoring timing of a first SS set is linked to the monitoring timing of a second SS set when different SS sets are in the same or different time slots. For example, UE 115 can determine that PDCCH candidates in the first and second SS sets are in the same time slot based on a monitoring mode configured for the SS sets, such as by means of RRC parameters (e.g., monitoringSlotPeriodicityAndOffset parameters). When two SS sets have the same period and the same offset, UE 115 can determine that SS sets in the same time slot are linked. In some instances, the duration of the monitoring mode can also be the same. In such instances, UE 115 may anticipate the same number of monitoring timings for each SS set within the time slot (e.g., the RRC parameter monitoring symbolsWithinSlot can be the same for each SS set). UE 115 can determine that each SS set has the same number of monitoring timings, and that monitoring timings with a first index value in the first SS set are linked to monitoring timings with the same index value in the second SS set.

[0089] In some configurations, the UE 115 of the wireless communication system 100 can be configured to have up to three CORESETs within a given BWP. A CORESET may include one or more Transmission Configuration Indicator (TCI) states for PDCCH repetition, and may be associated with the number of resource blocks (RBs) in the frequency domain and the number of symbols or other TTIs (e.g., the number of OFDM symbols) in the time domain. In some configurations, the CORESET configured at the UE 115 may be associated with: CCE Resource Element Group (CCE-REG) mapping type (e.g., CCE-REG accompanying mapping type), precoding nuances, identifiers associated with scrambling for the PDCCH demodulation reference signal (DMRS) (e.g., scrambling identifiers), encoded bits of downlink control information (DCI) content, or any combination thereof.

[0090] In some configurations, UE 115 can be configured to have up to ten SS sets within a given BWP. In some configurations, each SS set can be associated with a given CORESET and can include a set of monitoring opportunities. In some configurations, an SS set can include a set of control channel monitoring opportunities (e.g., PDCCH monitoring opportunities). Furthermore, UE 115 can be configured to determine the control channel monitoring opportunities associated with a given SS set based on one or more characteristics that can be configured at UE 115 (e.g., pre-configured), indicated to UE 115 via base station 105, or both. UE 115 can be configured to have one or more different types of SS sets (e.g., searchSpaceType), including UE-specific SS sets, public SS sets, or both. Alternatively, each SS set can be associated with one or more DCI formats to be monitored.

[0091] SS Collection ( The parameters can include the monitoring timing (e.g., The period of (each time slot) ), offset in time slots for monitoring timing ( )(For example, (e.g., monitoringSlotPeriodicityAndOffset), indicating the duration of the number of slots within a period in which an SS set exists. )(in (or any combination thereof). The UE 115 of the wireless communication system 100 can determine the time slot. Hexun Box The number of PDCCH monitoring opportunities within, if In some configurations, when monitoring the control channel, UE 115 can be configured to target the slave time slot. The beginning The SS set s within a consecutive time slot is used to monitor control channel candidates (e.g., PDCCH candidates), and can avoid targeting the next... The SS set s within a consecutive time slot is used to monitor control channel candidates. The number of control channel candidates (e.g., PDCCH candidates) can be based on the aggregation level of radio communications performed at UE 115 (e.g., the number of CCEs).

[0092] In some configurations, UE 115 can be configured to monitor the control channel (e.g., monitoringSymbolsWithinSlot) based on the control channel monitoring mode (e.g., PDCCH monitoring mode) within the time slot. For example, the PDCCH monitoring mode within the time slot can indicate the first symbol of the CORESET used for PDCCH monitoring within the time slot. For example, in the context of a time slot comprising fourteen symbols, the CORESET configured at UE 115 can be associated with an SS set comprising three symbols, and the control channel monitoring mode associated with the SS set (e.g., monitoringSymbolsWithinSlot) can be configured as "01000010001000". In this example, UE 115 can be configured to determine that three monitoring opportunities exist within each time slot where the SS set exists. Furthermore, UE 115 can be configured to determine that the three monitoring opportunities begin at the second, seventh, and eleventh symbols of each corresponding time slot where the SS exists.

[0093] In the context of SFN, an SFN PDCCH transmission (e.g., PDCCH DMRS) can be associated with two TCI states. Specifically, for an SFN PDCCH transmission, a CORESET can be initiated at a UE 115 with two active TCI states. In this case, each control channel candidate (e.g., PDCCH candidate) of the SS set associated with the CORESET can be associated with the two active TCI states of the CORESET.

[0094] Similarly, for a PDCCH repeat in which each PDCCH repeat includes a PDCCH candidate, two PDCCH candidates (e.g., two PDCCH repeats) can be concatenated (e.g., associated) with possible repeats (e.g., DCI repeats) for the same control channel transmission. In the context of a PDCCH repeat, the payloads (e.g., DCI payloads) of the two PDCCH candidates (e.g., two PDCCH repeats) can be identical. For example, a first PDCCH candidate can be associated with or concatenated with a second PDCCH candidate. In this example, a first DCI repeat can be transmitted in a first PDCCH candidate, and a second DCI repeat can be transmitted in a second PDCCH candidate, where the first and second DCI repeats are identical. In this example, UE 115 can receive and / or decode only the first DCI repeat or only the second DCI repeat. Alternatively or additionally, UE 115 can receive and / or decode both the first and second DCI repeats by performing a soft combination of the first and second DCI repeats. In some cases, related / linked PDCCH candidates may have the same aggregation level (e.g., the same number of CCEs).

[0095] In some configurations, related PDCCH candidates associated with corresponding CORESETs in different SS sets can be linked together (e.g., correlated) for PDCCH repetition. In some cases, two PDCCH candidates with the same candidate index across two related SS sets can be linked or correlated. In other cases, PDCCH candidates with the same starting CCE index can be linked. In some configurations, the related / linked set of PDCCH candidates can be configured via control signal transmission (e.g., RRC signal transmission). For example, UE 115 can receive an RRC message indicating that a first PDCCH candidate in a first SS set is linked (e.g., correlated) with a second PDCCH candidate in a second SS set. Furthermore, UE 115 can be configured to have linked / related PDCCH candidate sets within the same time slot or TTI (e.g., intra-slot PDCCH repetition), linked / related PDCCH candidate sets within different time slots (e.g., intra-slot PDCCH repetition), or both.

[0096] In some instances, UE 115 can determine that monitoring times for different SS sets are located in different time slots based on a monitoring mode (e.g., configured for each SS set via RRC parameters such as monitoringSlotPeriodicityAndOffset), where the two SS sets have the same period but different offsets. UE 115 can determine to satisfy one or more rules such that the first PDCCH repetition in the first SS set is always located in a time slot earlier than the second PDDCH repetition in the second SS set. In such an instance, UE 115 can determine to link monitoring times with a first index value in the first SS set with monitoring times with the same index value in the second SS set.

[0097] Figure 2 illustrates an example of a wireless communication system 200 supporting SS set monitoring for PDCCH repetition, according to various forms of this disclosure. The wireless communication system can implement various forms of wireless communication system 100. For example, wireless communication system 200 may include base station 205 and UE 215, which may be instances of the corresponding devices described with reference to Figure 1. Base station 205 may serve one or more UEs 215 located within coverage area 110-a.

[0098] In some configurations, UE 215 can be configured to have one or more cores in the BWP of the serving cell. For example, UE 215 can be configured to have three, five, or some other number of cores in the BWP configured by base station 205. Typically, each core can be associated with an active Transport Configuration Indicator (TCI) state. For example, as part of the core configuration for UE 215 performed by base station 205, the number of resource blocks (RBs) of the core in the frequency domain and the number of symbols (e.g., one, two, or three OFDM symbols) of the core in the time domain can be configured for UE 215 by RRC.

[0099] In some instances, the wireless communication system 200 may support PDCCH monitoring in one or more SS sets. In some cases, each SS set may be associated with a CORESET. For example, there may be up to ten SS sets in a component carrier (CC) BWP. As part of the SS set configuration, RRC signal delivery may be used to configure the associated CORESET, the period and offset of the monitored time slots, and the symbols to be monitored within the time slots in the time domain, the DCI format to be monitored, or the number of PDCCH candidates for a given aggregation level (AL). PDCCH candidates may be defined as part of the SS set configuration. For example, a PDCCH candidate with a given AL in a given PDCCH candidate index may be defined in a given SS set. The DCI may be delivered within a PDCCH candidate. For example, base station 205 can be configured with a first SS set including multiple PDCCH monitoring opportunities 210 (e.g., monitoring opportunity 210-a, monitoring opportunity 210-b, and monitoring opportunity 210-c) and a second SS set including multiple PDCCH monitoring opportunities 220 (e.g., monitoring opportunity 220-a, monitoring opportunity 220-b, and monitoring opportunity 220-c). Each monitoring opportunity can be configured to have one or more PDCCH candidates (e.g., PDCCH candidates included in monitoring opportunity 210, PDCCH candidates included in monitoring opportunity 220, etc.).

[0100] In some instances, each SS set (e.g., the first SS set including monitoring time 210) can be defined by one or more parameters. For example, the first SS set can correspond to CORESET and one or more PDCCH monitoring time 210. The parameters of the SS set(s) can include the monitoring time (e.g., The period of (time slots) ), offset in time slots for monitoring timing ( )(For example, (5 time slots). For example, the first SS set s=1 can have 5 time slots with a period of 230 ( The offset of 225 and 0 time slots 230 ( Base station 205 can configure the SS set period and offset via RRC messages (e.g., monitoringSlotPeriodicityAndOffset). The SS set can be further configured via duration (…). Defined by ), the duration indicates the number of time slots (in which) exist during the time period of the SS set. For example, the first SS set s=1 can have a duration of 230 for 2 time slots. 235. In some instances, base station 205 can configure UE 215 to monitor control signal transmissions in the SS set by indicating a PDCCH monitoring mode with TTI (e.g., time slot 230). For example, the RRC parameter (e.g., monitoringSymbolsWithinSlot) can indicate the first symbol of the CORESET in the time slot 230 used for monitoring. For example, for a CORESET with three symbols 240, the RRC parameter can indicate the first symbol (e.g., symbol 2 of time slot 230), the second symbol (e.g., the seventh symbol of time slot 230), and the third symbol (e.g., the eleventh symbol of time slot 230). The first indicated symbol can be the first symbol in the first monitoring time 210-d in time slot 230, the second symbol can be the first symbol in the second monitoring time 210-e in time slot 230, and the third symbol can be the first symbol in the third monitoring time 210-f. The bit image used to indicate this configuration of time slot 230 can be configured as "01000010001000".

[0101] UE 215 can monitor PDCCH candidates in various SS sets to receive one or more DCI messages. UE 215 can determine if a PDCCH candidate has passed a Cyclic Redundancy Check (CRC) check (e.g., UE 215 can attempt blind decoding for each PDCCH candidate using a blind decoding attempt where the PDCCH candidate has passed the CRC check corresponding to a successfully decoded DCI). In some wireless communication systems, there may be a limit (e.g., a maximum number) on the monitored PDCCH candidates that UE 215 can attempt to blind decode (e.g., a blind decoding limit, which may also be called a maximum blind decoding count, BD limit, monitored PDCCH candidate limit, etc.). The blind decoding limit (BD limit) can be based on a given transmission time interval (e.g., a time slot, span, or other duration in the time domain). Therefore, in any given TTI, the UE can be configured to have one or more PDCCH candidates. PDCCH candidates can correspond to different SS sets. The UE can count some or all of the PDCCH candidates towards the BD limit.

[0102] Some wireless communication systems can enable PDCCH transmission with two active TCI states. Variations of this approach may include a CORESET with two active TCI states, a set of SS associated with two different CORESETs, or two sets of SS associated with corresponding CORESETs. In the case where a CORESET is associated with two active TCI states, base station 205 can configure a PDCCH candidate (in a given set of SS) to be associated with both TCI states of the CORESET. In another approach where a CORESET can be associated with two active TCI states, base station 205 can configure two sets of PDCCH candidates (in a given set of SS) to be associated with each of the two active TCI states of the CORESET. In yet another approach where a CORESET can be associated with two active TCI states, base station 205 can configure two sets of PDCCH candidates to be associated with two corresponding SS sets, wherein both SS sets are associated with the CORESET, and each SS set is associated with only one TCI state of the CORESET. Typically, the PDCCH candidate set may include one or more PDCCH candidates, and the PDCCH candidates in the set correspond to the repetition or opportunity of DCI that can be indicated to UE 215.

[0103] The PDCCH candidate sets in various SS sets can provide repeat-based PDCCH candidates, where each PDCCH candidate is linked to other PDCCH candidates. For example, PDCCH candidates in the first SS set may be located in monitoring time slot 210-a, and may be linked to PDCCH candidates located in monitoring time slot 220-a of the second SS set. The PDCCH candidates in the first SS set and the PDCCH candidates in the second SS set may be located in the same time slot or in different time slots. In some instances, base station 205 can use PDCCH repeat to send DCI messages on two linked PDCCH candidates. For example, base station 205 can send a first repeat of the DCI message on the PDCCH candidates in the first SS set, and a second repeat of the DCI message on the PDCCH candidates in the second SS set. In some instances, UE 215 can perform a soft combination procedure on the PDCCH candidates received in the first SS set and the second SS set to generate soft-combined PDCCH candidates. The UE can treat the soft-combined PDCCH candidates as additional monitored PDCCH candidates.

[0104] In some instances, two or more PDCCH candidates may be explicitly linked together (e.g., base station 205 may configure a link to UE 215 before UE 215 attempts to perform blind decoding of the PDCCH candidates). In some instances, two or more PDCCH candidates may not be explicitly linked together, and UE 215 may identify or otherwise determine the link after or before decoding. However, some radio communication systems do not provide mechanisms or other indications regarding how one or more PDCCH candidates are counted when monitoring is applied to blind decoding limits configured for UE 215.

[0105] Therefore, as described herein, the monitoring timing for different SS sets can depend on the SS set configuration, including the time period, offset, duration, and monitoring timing within the time slot (e.g., as indicated in various RRC parameters such as monitoringSlotPeriodicityAndOffset, Duration, and monitoringSmbolsWithinSlot for the corresponding SS set). For PDCCH repetition, the monitoring timings of the two SS sets can also be linked when two linked PDCCH candidates are in different SS sets, because the linked PDCCH candidates are defined within a given monitoring timing of a given SS set. Therefore, UE 215 may need to determine which monitoring timings of the first SS set are linked to which monitoring timings of the second SS set. In some instances, UE 215 can identify whether monitoring timings in different SS sets within the same TTI (e.g., time slot) are linked, as described in more detail with reference to FIG3. In some instances, UE 215 can identify whether monitoring timings in different SS sets within different TTIs (e.g., time slots) are linked, as described in more detail with reference to FIGS. 4 through 6.

[0106] Figure 3 illustrates an example of an isochronous line 300 supporting SS set monitoring for PDCCH repetition according to various configurations of this disclosure. The isochronous line 300 can implement various configurations of wireless communication system 100 and wireless communication system 200. For example, a base station and a UE can communicate based on the isochronous line 300, and the base station and UE can be examples of the corresponding devices described with reference to Figures 1 and 2.

[0107] In some instances, a base station can configure a UE to have multiple SS sets within the same TTI (e.g., time slot 305) (e.g., indications of two SS set indices for a first SS set and a second SS set). The base station can configure a first monitoring timing 315-a and a second monitoring timing 315-b for the first SS set, and can also configure a first monitoring timing 320-a and a second monitoring timing 320-b for the second SS set. The UE can expect the two SS sets to be configured with the same period and the same offset (e.g., the same value for monitoringSlotPeriodicityAndOffset). The first SS set and the second SS set can further have the same duration. Having the same period, offset, duration, or any combination thereof may result in PDCCH repetition within the time slot.

[0108] In some instances, the UE can anticipate the same number of monitoring opportunities for two SS sets within time slot 305-a. For example, the UE can verify that the same number of 1s exist in the RRC indication (e.g., monitoringSymbolsWithinSlot) for the first SS set as in the RRC indication (e.g., monitoringSymbolsWithinSlot) for the second SS set. In such an instance, the UE can determine that monitoring opportunities with the same index value (j) in the two SS sets are linked. For example, the first SS set can be configured with an RRC parameter monitoringSymbolsWithinSlot including two 1s (e.g., bit map 00100001000000), which can indicate (e.g., associated with a CORESET with 2 symbols) that monitoring opportunity 315-a begins during the third symbol 310 of time slot 305-a, and monitoring opportunity 315-b begins during the eighth symbol 310 of time slot 305-a. The second SS set can be configured with an RRC parameter `monitoringSymbolsWithinSlot` (bit map 00100001000000) including two 1s. This can indicate (e.g., associated with a CORESET having two symbols) that monitoring opportunity 320-a begins during the third symbol 310 of time slot 305-a, and monitoring opportunity 320-b begins during the eighth symbol 310 of time slot 305-a. Because both bit maps include the same number of 1s, indicating the same number of monitoring opportunities, the UE can verify the existence of the same number of monitoring opportunities within time slot 305-a. Therefore, the UE can determine that monitoring opportunity 315-a of the first SS set is associated with monitoring opportunity 320-a of the second SS set (e.g., the first monitoring opportunity of each SS set has the same index value), and can determine that monitoring opportunity 315-b of the first SS set is associated with monitoring opportunity 320-b of the second SS set (e.g., the second monitoring opportunity of each SS set has the same index value). Each PDCCH candidate in the linked monitoring time can be linked together for PDCCH repetition.

[0109] Similarly, even if the TTI boundaries (e.g., symbol boundaries) of the monitoring timings are misaligned, the UE can determine whether the monitoring timings of different SS sets are linked based on the number of monitoring timings verified within the TTI. For example, in time slot 305-b, the UE can verify that the same number of 1s exist in the RRC indication (e.g., monitoringSymbolsWithinSlot) for the first SS set as in the RRC indication (e.g., monitoringSymbolsWithinSlot) for the second SS set. The first SS set can be configured with an RRC parameter monitoringSymbolsWithinSlot (e.g., bit map 00100001000000) including two 1s, which can indicate (e.g., associated with a CORESET with 2 symbols) that monitoring timing 325-a begins during the third symbol 310 of time slot 305-a, and monitoring timing 325-b begins during the eighth symbol 310 of time slot 305-b. The second SS set can be configured with an RRC parameter `monitoringSymbolsWithinSlot` (bit image 10000000010000) including two 1s. This can indicate (e.g., associated with a CORESET having 2 symbols) that monitoring opportunity 330-a begins during the first symbol 310 of time slot 305-b, and that monitoring opportunity 330-b begins during the tenth symbol 310 of time slot 305-b. Because both bit images include the same number of 1s, indicating the same number of monitoring opportunities, the UE can verify the presence of the same number of monitoring opportunities within time slot 305-b. Therefore, the UE can determine that monitoring opportunity 325-a of the first SS set is associated with monitoring opportunity 330-a of the second SS set (e.g., the first monitoring opportunity of each SS set has the same index value), and can determine that monitoring opportunity 325-b of the first SS set is associated with monitoring opportunity 330-b of the second SS set (e.g., the second monitoring opportunity of each SS set has the same index value). Each PDCCH candidate in the linked monitoring time can be linked together for PDCCH repetition.

[0110] Therefore, in time slot 305 where two SS sets exist, the j-th monitoring time of the first SS set can be linked with the j-th monitoring time of the second SS set. The first repetition of the control message (e.g., DCI message) can be received in the first PDCCH candidate in the first monitoring time (e.g., monitoring time 325-a) of the first SS set, and the second repetition of the control message (e.g., DCI message) can be received in the first PDCCH candidate (e.g., linked with the first PDDCH candidate in monitoring time 325-a) of the first monitoring time (e.g., monitoring time 330-a) of the second SS set. The UE can perform soft combination of the DCI received in the first PDCCH candidate of the first SS set and the DCI received in the first PDDCH candidate of the second SS set.

[0111] In some instances, the UE can determine which monitoring times of different SS sets located in different TTIs are linked, as described in more detail with reference to Figures 4 to 6.

[0112] Figure 4 illustrates an example of an isochronous line 400 supporting SS set monitoring for PDCCH repetition according to various configurations of this disclosure. The isochronous line 400 can implement various configurations of wireless communication system 100 and wireless communication system 200. For example, a base station and a UE can communicate based on the isochronous line 400, and the base station and UE can be examples of the corresponding devices described with reference to Figures 1 and 2.

[0113] In some instances, the base station can be configured to have a first SS set and a second SS set for the UE. The first SS set and the second SS set can have the same period. However, they can have different offset values ​​(e.g., for the first SS set). , and for the second SS set as If the UE can support PDCCH repetition between time slots in consecutive time slots, the base station can configure offsets for two SS sets, such that the period and the two offset values... .

[0114] The base station can configure the UE to have a pair of SS set indices for inter-slot PDCCH repetition. The UE can expect two SS sets to be configured with the same period of more than one time slot (e.g., However, they have different offsets (e.g., respectively). and In this instance, if one or more rules or conditions are met, it includes a first time slot for monitoring the first SS set (e.g., in a slot with a frame number). The frame has an SCS scheme Time slot number The first time slot, having the number of time slots per frame. ( ), making It can be used with a second time slot (e.g., having a time slot number) that includes the monitoring timing for the second SS set. Hsin Frame Number (The time slots) are connected.

[0115] The UE can decide to satisfy one or more rules such that the first PDCCH repetition in the first SS set is temporally earlier than (e.g., in an earlier TTI) the second PDCCH repetition in the second SS set. For example, the UE can verify that a first condition is satisfied, wherein if ,but In some instances, the UE can verify that the second condition is met, where . The UE may apply one, two, or additional conditions from these conditions. Verifying that such a condition or rule is met may result in the first repetition of the first SS set preceding the second repetition of the second SS set.

[0116] For example, a base station can be configured to have a first SS set for the UE. Second SS episode ,in , , And assuming the SCS is 30 kHz and the number of time slots per frame. Time slot 405-a may include the monitoring timing of the first SS set, and may have a time slot number of 16. Therefore, . + Time slot 410-b, located two time slots later than time slot 405-a, may include the monitoring timing of the second SS set and may have time slot number 18. Therefore, . + The UE can determine that the monitoring timing of the first SS set located in time slot 405-a is linked to the monitoring timing of the second SS set located in time slot 410-b, and similarly, determine that the monitoring timing in time slot 405-b is linked to the monitoring timing in time slot 410-c. By applying one or more conditions described herein, the UE can ensure that the first repetition of the DCI message is temporally earlier than the second repetition of the DCI message (e.g., time slot 405-a for carrying the first repetition is linked to time slot 410-b for carrying the second repetition, rather than time slot 410-a for carrying the second repetition being earlier than time slot 405-a).

[0117] In some instances, the base station can be configured to have a first SS set for the UE. Second SS episode ,in , , And assuming the SCS is 30 kHz and the number of time slots per frame. Time slot 415-a may include the monitoring timing of the first SS set, and may have a time slot number of 19. Therefore, . + Time slot 420-b, located later than time slot 415-a, may include the monitoring timing of the second SS set, and may have time slot number 0 (e.g., the first time slot of the next frame). Therefore, . + 40. The UE can determine that the monitoring timing of the first SS set located in time slot 415-a is linked to the monitoring timing of the second SS set located in time slot 420-b. By applying one or more conditions described herein, the UE can ensure that the first repetition of the DCI message is temporally earlier than the second repetition of the DCI message (e.g., time slot 415-a for carrying the first repetition is linked to time slot 420-b for carrying the second repetition, rather than time slot 420-a for carrying the second repetition being earlier than time slot 415-a). This pattern can be repeated for subsequent time slots. For example, the UE can determine that the monitoring timing of the first SS set located in time slot 415-b is linked to the monitoring timing of the second SS set located in time slot 420-c.

[0118] In some instances, the order of SS sets may affect the application of conditions or the determination of linkage between monitoring times, or both. For example, the second SS set may precede the first SS set, such that the monitoring times in the second SS set carry a first repetition of the PDCCH message, and the monitoring times in the second SS set carry a second repetition of the DCI message. In such instances, the UE may verify that one or more rules are satisfied, and may determine, for example, that time slot 410-a of the second SS set is linked to time slot 405-a, and time slot 410-b is linked to time slot 405-b.

[0119] In some instances, the UE can determine which SS set precedes or takes precedence over another SS set. For example, the UE can sort the two SS sets based on a configuration performed by the base station. In such an instance, the base station can send a configuration message to the UE indicating, for example, that the first SS set is ranked first (e.g., prioritized as the first SS set) and the second SS set is ranked second. The configuration message may indicate that the first SS set with an index value of 4 and the second SS set with an index value of 2 are linked, and may further indicate that the first SS set (e.g., index value 4) is ranked before the second SS set (e.g., index value 2). In some instances, the UE can implicitly determine the order of linked SS sets. For example, the UE can determine which SS set has a higher or lower index value (e.g., according to one or more pre-configured, normalized, or configured rules). In this example, when a first SS set with an index value of 4 and a second SS set with an index value of 2 are linked, the UE can decide that the SS set with the smaller index value (e.g., the second SS set with an index value of 2) can be placed before the first SS set (e.g., the first SS set with a larger index value of 4). If the order of the SS sets changes, the time slot for the repeated links of the PDCCH can be changed, as described herein.

[0120] Inter-slot repetition in the case of consecutive slots is described in more detail with reference to FIG5.

[0121] Figure 5 illustrates an example of an isochronous line 500 supporting SS set monitoring for PDCCH repetition according to various configurations of this disclosure. The isochronous line 500 can implement various configurations of wireless communication system 100 and wireless communication system 200. For example, a base station and a UE can communicate based on the isochronous line 500, and the base station and UE can be examples of the corresponding devices described with reference to Figures 1 and 2.

[0122] In some instances, regarding the duration of an SS set, the UE may expect the SS set to exist only within a time slot during a time period (e.g., two SS sets are configured with durations). Alternatively, the base station may not configure a value, and the UE may assume the duration of a time slot. For example, the duration of a time slot (whether configured or assumed) is shown and described with reference to FIG4.

[0123] In some instances, the duration may be longer than one time slot, but for each SS set, the duration may be the same, as described with reference to Figure 5. For example, the first SS set may have The duration. In this example, the UE can determine the link between the first time slot of the time period in the SS set and the first time slot of the time period in the second SS set, and can assume that the remaining time slots for such duration are mapped 1:1. For example, time slot 505-a could be The first time slot, in which Time slot 505-a may include monitoring timing for the first SS set, and time slot 510-a may include monitoring timing for the second SS set. Time slot 505-a may have time slot number 16, so... . + Time slot 510-a can have time slot number 18 (e.g., in the same frame), so . + Therefore, by applying one or more rules described with reference to FIG4, the UE can determine the connection between time slot 505-a and time slot 510-a, and the connection between each PDCCH candidate of the monitoring period of the first SS set in time slot 505-a and the corresponding PDCCH candidate of the monitoring period of the second SS set in time slot 510-a. Subsequently, given For the duration, the UE can decide to connect the second time slot 505-b and the second time slot 510-b with the same duration, and connect the third time slot 505-c and the third time slot 510-c with the same duration.

[0124] In some instances, the UE can be configured for continuous inter-slot repetition, and can be configured to have an offset value, such that... .

[0125] In some instances, there may be multiple monitoring opportunities within a linked time slot, as described in more detail with reference to Figure 6.

[0126] Figure 6 illustrates an example of an isochronous line 600 supporting SS set monitoring for PDCCH repetition according to various configurations of this disclosure. The isochronous line 600 can implement various configurations of wireless communication system 100 and wireless communication system 200. For example, a base station and a UE can communicate based on the isochronous line 600, and the base station and UE can be examples of the corresponding devices described with reference to Figures 1 and 2.

[0127] A base station can configure one or more monitoring opportunities within a single time slot (e.g., via the RRC parameter monitoringSymbolsWithinSlot). In some instances, for cases where the PDCCH overlaps between time slots, the number of monitoring opportunities in each time slot can be equal to one (e.g., for two SS sets, the number of 1s in the bit map of the RRC parameter monitoringSymbolsWithinSlot can be equal to 1). In such instances, the UE can decide to link a single monitoring opportunity in a first time slot of the first SS set to a unique monitoring opportunity in the linked time slot of the second SS set. In some instances, the linking of monitoring time slots can be implicit based on the linking of time slots as described with reference to Figures 4 and 5. In some cases, the base station may be restricted to configuring no more than one monitoring opportunity per time slot of linked SS sets in different time slots.

[0128] In some instances, a base station may be permitted to configure more than one monitoring opportunity in each time slot of two linked SS sets. The UE may anticipate the same number of monitoring opportunities for both SS sets within the linked time slots (e.g., possibly anticipating the same number of 1s in the bit map of the RRC parameter monitoringSymbolsWithinSlot). In linked time slots 605-a and 605-c, where both SS sets exist, in the first time slot 605-a (e.g., time slot...),... The j-th monitoring timing of the first SS set in ) can be synchronized with the second time slot 605-c (e.g., The second SS set in the second SS set is linked to the j-th monitoring opportunity, in which and These are two different time slots determined according to the rules described with reference to FIG4. The first repetition of the control message (e.g., DCI message) may be received in the first PDCCH candidate in the first monitoring time (e.g., monitoring time 610-a) of the first SS set, and the second repetition of the control message (e.g., DCI message) may be received in the first PDCCH candidate (e.g., associated with the first PDDCH candidate in monitoring time 610-a) of the first monitoring time (e.g., monitoring time 615-a) of the second SS set. The UE may soft-combine the DCI received in the first PDCCH candidate of the first SS set with the DCI received in the first PDDCH candidate of the second SS set.

[0129] In some instances, the UE can determine that time slots 605-a and 605-c are linked (e.g., using one or more rules described with reference to Figures 4 and 5). Monitoring opportunities 610-a and 610-b for the first SS set can be located in time slot 605-a, and monitoring opportunities 615-a and 615-b for the second SS set can be located in time slot 605-c. The UE may anticipate the same number of monitoring opportunities for both SS sets within time slot 605-a. For example, the UE can verify that the same number of 1s exists in the RRC indication (e.g., monitoringSymbolsWithinSlot) for the first SS set as it does in the RRC indication (e.g., monitoringSymbolsWithinSlot) for the second SS set. In such an instance, the UE can determine that monitoring opportunities with the same index value (j) in both SS sets are linked.

[0130] For example, a first SS set can be configured with an RRC parameter monitoringSymbolsWithinSlot including two 1s (e.g., bitmap 00100001000000), which can indicate (e.g., associated with a CORESET having two symbols 620) that monitoring timing 610-a begins during the third symbol 620 of time slot 605-a, and monitoring timing 610-b begins during the eighth symbol 620 of time slot 605-a. A second SS set can be configured with an RRC parameter monitoringSymbolsWithinSlot including two 1s (bitmap 10000000001000), which can indicate (e.g., associated with a CORESET having two symbols) that monitoring timing 615-a begins during the first symbol 620 of time slot 605-a, and monitoring timing 615-b begins during the eleventh symbol 620 of time slot 605-c. Because both bitmaps contain the same number of 1s, indicating the same number of monitoring opportunities, the UE can verify the existence of the same number of monitoring opportunities within time slots 605-a and 605-b. Therefore, the UE can decide to link monitoring opportunities 615-a of the first SS set with those of the second SS set (e.g., the first monitoring opportunities of each SS set have the same index value), and can decide to link monitoring opportunities 610-b of the first SS set with those of the second SS set (e.g., the second monitoring opportunities of each SS set have the same index value). The individual PDCCH candidates in the linked monitoring opportunities can be linked together for PDCCH repetition.

[0131] In the connected time slots 605-a and 605-c, where two SS sets exist, the j-th monitoring time of the first SS set can be linked with the j-th monitoring time of the second SS set. The first repetition of a control message (e.g., a DCI message) can be received in the first PDCCH candidate of the first monitoring time (e.g., monitoring time 325-a) of the first SS set, and the second repetition of a control message (e.g., a DCI message) can be received in the first PDCCH candidate (e.g., linked to the first PDDCH candidate in monitoring time 325-a) of the first monitoring time (e.g., monitoring time 330-a) of the second SS set. The UE can soft-combine the DCI received in the first PDCCH candidate of the first SS set with the DCI received in the first PDDCH candidate of the second SS set.

[0132] Figure 7 illustrates a block diagram 700 of a device 705 supporting SS set monitoring for PDCCH repetition according to various forms of this disclosure. Device 705 may be an example of a UE 115 as described herein. Device 705 may include a receiver 710, a transmitter 715, and a communications manager 720. Device 705 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0133] Receiver 710 may provide components for receiving information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels related to SS set monitoring for PDCCH repetition).
