Description

Multi-time slot physical downlink control channel monitoring In summary, this disclosure relates to wireless communication and to techniques and apparatus for monitoring downlink control channels in multi-time slot entities. Wireless communication systems are widely deployed to provide a variety of telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiplexing access technologies that support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power). Examples of such multiplexing access technologies include Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), Time Division Synchronous Code Division Multiple Access (TD-SCDMA), and Long Term Evolution (LTE). LTE / LTE Advanced is a collection of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile service standard released by the 3rd Generation Partnership Project (3GPP). A wireless network may include one or more network nodes that support communication for wireless communication devices, such as user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink and uplink communication. A "downlink" (or "DL") refers to the communication link from the network node to the UE, and an "uplink" (or "UL") refers to the communication link from the UE to the network node. Some wireless networks may support device-to-device communication, such as via local links (e.g., sidelinks (SL), wireless local area network (WLAN) links, and / or wireless personal area network (WPAN) links). The aforementioned multiplexing access technologies have been adopted in various telecommunications standards to provide common protocols enabling different UEs to communicate at the city, country, region, and / or global levels. New Radio (NR), often referred to as 5G, is a collection of enhancements to the LTE mobile service standard released by 3GPP. NR is designed to better support mobile broadband internet access by: improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and better integration with other open standards using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on the downlink and CP-OFDM and / or Single Carrier Frequency Division Multiplexing (SC-FDM) (also known as Discrete Fourier Transform Spread Spectrum OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies, and carrier aggregation. Further improvements to LTE, NR, and other radio access technologies remain useful as the demand for mobile broadband access continues to grow. Some of the methods described herein relate to a method of wireless communication performed by a user equipment (UE). The method may include: receiving an indication to perform physical downlink control channel (PDCCH) monitoring in a first monitoring span of a first set of time slots and in a second monitoring span of a second set of time slots, wherein the start of the first monitoring span is at least a threshold number of time slots away from the start of the second monitoring span. The method may include: selectively performing PDCCH monitoring in either the first or second monitoring span, at least in part based on the indication. Some of the states described herein relate to a method of wireless communication performed by a network node. The method may include: sending instructions to perform PDCCH monitoring in a first monitoring span of a first set of time slots and in a second monitoring span of a second set of time slots, wherein the start of the first monitoring span is at least a threshold number of time slots away from the start of the second monitoring span. Some of the specifications described herein relate to an apparatus for wireless communication performed by a UE. The apparatus may include memory and one or more processors coupled to the memory. The one or more processors may be configured to receive instructions to perform PDCCH monitoring in a first monitoring span of a first set of time slots and in a second monitoring span of a second set of time slots, wherein the start of the first monitoring span is at least a threshold number of time slots away from the start of the second monitoring span.

It should be understood that any form of the disclosure disclosed herein can be embodied by one or more elements of a claim. Several aspects of a telecommunications system will now be presented with reference to various devices and technologies. These devices and technologies will be described in detail below and will be shown in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system. Although the terms generally associated with 5G or New Radio (NR) Radio Access Technology (RAT) may be used to describe the pattern herein, the pattern of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or RATs after 5G (e.g., 6G). Figure 1 is a schematic diagram illustrating an example of a wireless network 100 according to this disclosure. The wireless network 100 may be or may include elements of a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. Network node 110 is a network node that communicates with UE 120. As shown, network node 110 may include one or more network nodes. For example, network node 110 can be an aggregated network node, meaning that an aggregated network node is configured to utilize a stack of radio protocols that are physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, network node 110 can be a deaggregated network node (sometimes referred to as a deaggregated base station), meaning that network node 110 is configured to utilize a stack of protocols that are physically or logically distributed among two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)). In some instances, network node 110 is or includes a network node (such as an RU) that communicates with UE 120 via a radio access link. In some instances, network node 110 is or includes a network node (such as a DU) that communicates with other network nodes 110 via a fronthaul link or a midhaul link. In some instances, network node 110 is or includes a network node (such as a CU) that communicates with other network nodes 110 via a midhaul link or with the core network via a backhaul link. In some instances, network node 110 (such as an aggregated network node 110 or a deaggregated network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. Network node 110 may include, for example, NR base stations, LTE base stations, Node Bs, eNBs (e.g., in 4G), gNBs (e.g., in 5G), access points, transmit / receive points (TRPs), DUs, RUs, CUs, network mobility elements, core network nodes, network elements, network equipment, RAN nodes, or combinations thereof. In some instances, network nodes 110 may interconnect with each other or with one or more other network nodes 110 in the wireless network 100 using any suitable transport network via various types of fronthaul, midhaul, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks). In some instances, network node 110 can provide communication coverage for a specific geographic area. Within the 3GPP (3rd Generation Partnership Project), depending on the context in which the term is used, the term "cell" can refer to the coverage area of ​​network node 110 and / or the network node subsystem serving that coverage area. Network node 110 can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. Macrocells can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UE 120 with a service subscription. Picocells can cover a relatively small geographic area and can allow unrestricted access by UE 120 with a service subscription. Femtocells can cover a relatively small geographic area (e.g., a home) and can allow restricted access by UE 120 associated with a femtocell (e.g., UE 120 in a Closed Subscriber Group (CSG)). Network node 110 for macrocells can be referred to as a macro network node. Network nodes 110 for picocells can be referred to as pico nodes. Network nodes 110 for femtocells can be referred to as femto nodes or home network nodes. In the example shown in Figure 1, network node 110a can be a macro network node for macrocell 102a, network node 110b can be a pico node for picocell 102b, and network node 110c can be a femto node for femtocell 102c. Network nodes can support one or more (e.g., three) cells. In some instances, cells may not necessarily be stationary, and the geographic area of ​​a cell can move depending on the location of a moving network node 110 (e.g., a mobile network node). In some embodiments, the term "base station" or "network node" may refer to an aggregated base station, a deaggregated base station, an integrated access and backhaul (IAB) node, a relay node, or one or more of these components. For example, in some embodiments, "base station" or "network node" may refer to a CU, DU, RU, near-real-time (near-RT) RAN Intelligent Controller (RIC) or non-real-time (non-RT) RIC, or a combination thereof. In some embodiments, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with network node 110). In some embodiments, the term "base station" or "network node" may refer to a plurality of devices configured to perform one or more functions. For example, in some distributed systems, each of a number of different devices (which may be located in the same geographical location or in different geographical locations) can be configured to perform at least a portion of a function, or to replicate the execution of at least a portion of a function, and the terms "base station" or "network node" can refer to any one or more of these different devices. In some configurations, the terms "base station" or "network node" can refer to one or more virtual base stations or one or more virtual base station functions. For example, in some configurations, two or more base station functions can be generated as entities on a single device. In some configurations, the terms "base station" or "network node" can refer to one function of a base station function rather than another. In this way, a single device can include more than one base station. Wireless network 100 may include one or more relay stations. A relay station is a network node that receives data transmissions from an upstream node (e.g., network node 110 or UE 120) and sends data transmissions to a downstream node (e.g., UE 120 or network node 110). A relay station may be a UE 120 that can relay transmissions to other UEs 120. In the example shown in Figure 1, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between network node 110a and UE 120d. The network node 110 that relays communication may be referred to as a relay station, relay base station, relay network node, relay node, repeater, etc. Wireless network 100 can be a heterogeneous network comprising different types of network nodes 110 (such as macro nodes, piconet nodes, femtonet nodes, relay nodes, etc.). These different types of network nodes 110 can have different transmit power levels, different coverage areas, and / or different effects on interference in wireless network 100. For example, macro nodes can have high transmit power levels (e.g., 5 to 40 watts), while piconet nodes, femtonet nodes, and relay nodes can have lower transmit power levels (e.g., 0.1 to 2 watts). Network controller 130 may be coupled to or communicate with a set of network nodes 110, and provide coordination and control for such network nodes 110. Network controller 130 may communicate with network nodes 110 via a backhaul communication link or a midhaul communication link. Network nodes 110 may communicate with each other directly or indirectly via wireless or wired backhaul communication links. In some embodiments, network controller 130 may be a CU or a core network device, or may include a CU or a core network device. UE 120 can be distributed across the wireless network 100, and each UE 120 can be stationary or mobile. UE 120 may include, for example, access terminals, terminals, mobile stations, and / or user units. UE 120 may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop, a wireless phone, a wireless loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smart computer, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart instrument / sensor, industrial manufacturing equipment, a GPS device, the UE function of a network node, and / or any other suitable device configured to communicate via wireless or wired media. Some UEs 120 may be considered Machine-Type Communications (MTC) or Evolved or Enhanced Machine-Type Communications (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, instruments, monitors, and / or location tags, which can communicate with network nodes, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (Narrowband IoT) devices. Some UEs 120 may be considered customer premises equipment. UEs 120 may be included within a housing that houses the components of the UE 120, such as processor components and / or memory components. In some instances, the processor components and memory components may be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled. Typically, any number of wireless networks 100 can be deployed in a given geographical area. Each wireless network 100 can support a specific RAT and can operate on one or more frequencies. A RAT can be referred to as a radio technology, air interface, etc. A frequency can be referred to as a carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed. In some instances, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such instances, UE 120 may perform scheduling operations, resource selection operations, and / or other operations performed by network node 110 as described elsewhere herein. Devices in Wireless Network 100 can communicate using the electromagnetic spectrum, which can be subdivided into categories, bands, channels, etc., based on frequency or wavelength. For example, devices in Wireless Network 100 can communicate using one or more operating frequency bands. In 5G NR, two initial operating frequency bands have been identified as frequency ranges designated FR1 (410 MHz - 7.125 GHz) and FR2 (24.25 GHz - 52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is generally referred to as the "sub-6 GHz" band (interchangeably) in various documents and articles. A similar naming issue sometimes occurs with FR2, which is generally referred to as the "millimeter wave" band (interchangeably) in documents and articles, although this is different from the Extremely High Frequency (EHF) band (30 GHz - 300 GHz) designated as "millimeter wave" by the International Telecommunication Union (ITU). The frequencies between FR1 and FR2 are generally referred to as intermediate frequency (IF) bands. Recent 5G NR research has identified the operating bands used for these IF bands as the frequency range designated FR3 (7.125 GHz - 24.25 GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, and therefore, the features of FR1 and / or FR2 can be effectively extended into the IF band. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating frequency bands have been identified as the frequency ranges designated FR4a or FR4-1 (52.6 GHz - 71 GHz), FR4 (52.6 GHz - 114.25 GHz), and FR5 (114.25 GHz - 300 GHz). Each of these higher frequency bands falls within the EHF band. Considering the above examples, unless otherwise explicitly stated, it should be understood that when the term "sub-6 GHz" is used herein, it can broadly refer to frequencies that are below 6 GHz, within FR1, or may include intermediate frequency bands. Furthermore, unless otherwise explicitly stated, it should be understood that when the term "millimeter wave" is used herein, it can broadly refer to frequencies that may include intermediate frequency bands, within FR2, FR4, FR4-a, or FR4-1 and / or FR5, or within the EHF band. It is contemplated that frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) can be modified, and the techniques described herein are applicable to such modified frequency ranges. In some configurations, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive instructions to perform physical downlink control channel (PDCCH) monitoring in a first monitoring span of a first set of time slots and in a second monitoring span of a second set of time slots, wherein the start of the first monitoring span is at least a threshold number of time slots away from the start of the second monitoring span; and to selectively perform PDCCH monitoring in either the first or second monitoring span, at least in part, based on the instructions. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein. In some configurations, network node 110 may include communication manager 150. As described in more detail elsewhere herein, communication manager 150 may send instructions to perform PDCCH monitoring in a first monitoring span of a first set of time slots and in a second monitoring span of a second set of time slots, wherein the start of the first monitoring span is at least a threshold number of time slots away from the start of the second monitoring span. Additionally or alternatively, communication manager 150 may perform one or more other operations described herein. As noted above, Figure 1 is provided as an example. Other examples may differ from those described with respect to Figure 1. Figure 2 is a schematic diagram illustrating an example 200 of a network node 110 communicating with a user equipment (UE) 120 in a wireless network 100 according to the present disclosure. The network node 110 may be equipped with an array of antennas 234a to 234t, such as... T antennas ( T≧1). UE 120 can be equipped with an array of antennas 252a to 252r, such as R antennas ( R ≥1). Network node 110 of example 200 includes one or more radio frequency components, such as antenna 234 and modem 254. In some instances, network node 110 may include an interface, communication component, or other component facilitating communication with UE 120 or another network node. Some network node 110 may not include radio frequency components facilitating direct communication with UE 120, such as one or more CUs or one or more DUs. At network node 110, transmitting processor 220 can receive data intended for UE 120 (or a set of UE 120) from data source 212. Transmitting processor 220 can select one or more modulation and coding schemes (MCS) for UE 120, at least in part, based on one or more Channel Quality Indicators (CQIs) received from UE 120. Network node 110 can process (e.g., encode and modulate) the data for UE 120, at least in part, based on the MCS selected for UE 120, and provide data symbols for UE 120. Transmitting processor 220 can process system information (e.g., for Semi-Static Resource Partitioning (SRPI)) and control information (e.g., CQI requests, permission requests, and / or upper-layer signaling), and provide management burden symbols and control symbols. Transmit processor 220 can generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulated reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). Where applicable, transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, administrative burden symbols, and / or reference symbols, and can transmit to the corresponding set of data symbols (e.g., data symbols) of data processor 232. T data machines (shown as data machines 232a to 232t) provide a set of output symbol streams (e.g., T output symbol streams). For example, each output symbol stream can be provided to the modulator component (shown as MOD) of the data transmitter 232. Each data transmitter 232 can use a corresponding modulator component to process the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each data transmitter 232 can further use a corresponding modulator component to process the output sample stream (e.g., convert to analog, amplify, filter, and / or upconvert) to obtain a downlink signal. Data transmitters 232a to 232t can be connected via a corresponding set of antennas 234 (e.g., A set of T antennas (shown as antennas 234a to 234t) are used to transmit downlink signals (e.g., T downlink signals). At UE 120, the set of antennas 252 (shown as antennas 252a to 252r) can receive downlink signals from network node 110 and / or other network nodes 110, and can transmit signals to the set of modems 254 (e.g., R data machines (shown as data machines 254a to 254r) provide a set of received signals (e.g., R received signals. For example, each received signal can be provided to the demodulator component (shown as DEMOD) of the modem 254. Each modem 254 can use a corresponding demodulator component to condition the received signal (e.g., filter, amplify, downconvert, and / or digitize) to obtain an input sample. Each modem 254 can use the demodulator component to further process the input sample (e.g., for OFDM) to obtain the received symbols. The MIMO detector 256 can obtain the received symbols from the modem 254, can perform MIMO detection on the received symbols (if applicable), and can provide the detected symbols. The receiver processor 258 can process (e.g., demodulate and decode) the detected symbols, can provide decoded data for UE 120 to data slot 260, and can provide decoded control information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine parameters such as the Received Reference Power (RSRP), Received Signal Strength Indicator (RSSI), Received Reference Quality (RSRQ), and / or CQI. In some instances, one or more components of the UE 120 may be included in the housing 284. Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in a core network. Network controller 130 may communicate with network node 110 via communication unit 294. One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc., or may be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or one or more antenna elements coupled to one or more transmitting and / or receiving components (such as one or more components in FIG. 2). On the uplink, at UE 120, the transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 can generate reference symbols for one or more reference signals. Symbols from the transmit processor 264 can be pre-encoded by the TX MIMO processor 266 (if applicable), further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to network node 110. In some instances, the modem 254 of UE 120 may include a modulator and demodulator. In some instances, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver can be used by a processor (e.g., controller / processor 280) and memory 282 to perform any of the methods described herein (e.g., see Figures 7 through 14). At network node 110, uplink signals from UE 120 and / or other UEs can be received by antenna 234, processed by modem 232 (e.g., a demodulator component of modem 232 shown as DEMOD), detected by MIMO detector 236 (if applicable), and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide decoded data to data slot 239 and decoded control information to controller / processor 240. Network node 110 may include communication unit 244 and can communicate with network controller 130 via communication unit 244. Network node 110 may include scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communication. In some instances, modem 232 of network node 110 may include modulator and demodulator. In some instances, network node 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform any of the methods described herein (e.g., refer to Figures 7 through 14). As described in more detail elsewhere herein, the controller / processor 240 of network node 110, the controller / processor 280 of UE 120, and / or any other component in Figure 2 may perform one or more techniques associated with multi-timeslot PDCCH monitoring. For example, the controller / processor 240 of network node 110, the controller / processor 280 of UE 120, and / or any other component in Figure 2 may perform or direct the operation of processes such as process 1100 of Figure 11, process 1200 of Figure 12, and / or other processes as described herein. Memory 242 and memory 282 may store data and program code for network node 110 and UE 120, respectively. In some instances, memory 242 and / or memory 282 may include non-transitory computer-readable media storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, when one or more instructions are executed by one or more processors of network node 110 and / or UE 120 (e.g., directly, or after compilation, transformation, and / or interpretation), they may cause one or more processors, UE 120, and / or network node 110 to perform or direct the operation of processes such as process 1100 of FIG. 11, process 1200 of FIG. 12, and / or other processes described herein. In some instances, the execution instructions may include run instructions, transformation instructions, compilation instructions, and / or interpretation instructions, etc. In some configurations, the UE includes: means for receiving an instruction to perform PDCCH monitoring in a first monitoring span of a first set of time slots and in a second monitoring span of a second set of time slots, wherein the start of the first monitoring span is at least a threshold number of time slots away from the start of the second monitoring span; and / or means for selectively performing PDCCH monitoring in the first or second monitoring span, at least in part, based on the instruction. The means for the UE to perform the operations described herein may include, for example, one or more of the following: communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282. In some configurations, the network node includes components for transmitting instructions to perform PDCCH monitoring in a first monitoring span of a first set of time slots and in a second monitoring span of a second set of time slots, wherein the start of the first monitoring span is at least a threshold number of time slots away from the start of the second monitoring span. Components for the network node to perform the operations described herein may include, for example, one or more of the following: a communication manager 150, a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246. Although the blocks in Figure 2 are shown as dissimilar components, the functions described above with reference to the blocks can be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 can be executed by or under the control of the controller / processor 280. As noted above, Figure 2 is provided as an example. Other examples may differ from those described with respect to Figure 2. Figure 3 is a schematic diagram illustrating an example resource structure 300 for wireless communication according to this disclosure. Resource structure 300 illustrates examples of various resource groups described herein. As shown, resource structure 300 may include sub-frames 305. Sub-frames 305 may include multiple time slots 310. Although resource structure 300 is shown as including 2 time slots per sub-frame, different numbers of time slots may be included in the sub-frames (e.g., 4 time slots, 8 time slots, 16 time slots, 32 time slots, or another number of time slots). In some cases, different types of transmission time intervals (TTIs) may be used in addition to sub-frames and / or time slots. Time slots 310 may include multiple symbols 315, such as 14 symbols per time slot. The potential control area of ​​time slot 310 may be referred to as a control resource set (CORESET) 320 and can be configured to support efficient use of resources, such as through flexible configuration or reconfiguration of resources in CORESET 320 for one or more PDCCHs and / or one or more entity downlink shared channels (PDSCHs). In some cases, CORESET 320 may occupy the first symbol 315 of time slot 310, the first two symbols 315 of time slot 310, or the first three symbols 315 of time slot 310. Therefore, CORESET 320 may include multiple resource blocks (RBs) in the frequency domain and one, two, or three symbols 315 in the time domain. In 5G, the number of resources included in CORESET 320 can be flexibly configured, such as by using Radio Resource Control (RRC) signaling to indicate the frequency domain area (e.g., the number of resource blocks) and / or time domain area (e.g., the number of symbols) for CORESET 320. As shown, symbol 315, including CORESET 320, may include one or more Control Channel Elements (CCEs) 325 spanning a portion of the system bandwidth (as an example, two CCEs 325 are shown). CCEs 325 may include downlink control information (DCI) for providing control information for wireless communication. A network node may transmit DCI during multiple CCEs 325 (as shown), where the number of CCEs 325 used for DCI transmission represents the aggregation level (AL) used by the BS for DCI transmission. In Figure 3, an aggregation level of two is shown as an example, corresponding to two CCEs 325 in time slot 310. In some cases, different aggregation levels (such as 1, 2, 4, 8, 16, or another aggregation level) may be used. Each CCE 325 may include a fixed number of resource element groups (REGs) 330 (shown as 6 REGs 330), or may include a variable number of REGs 330. In some configurations, the number of REGs 330 included in the CCE 325 may be specified by the REG appendage size. A REG 330 may include a resource block, which may include 12 resource elements (REs) 335 within a symbol 315. A resource element 335 may occupy a subcarrier in the frequency domain and an OFDM symbol in the time domain. The search space may include all possible locations where the PDCCH can be located (e.g., in time and / or frequency). CORESET 320 may include one or more search spaces, such as a UE-specific search space, a group-wide search space, and / or a common search space. The search space may indicate the set of CCE locations where the UE can find a PDCCH that may potentially be used to send control information to the UE. Possible locations for the PDCCH may depend on whether the PDCCH is a UE-specific PDCCH (e.g., for a single UE) or a group-wide PDCCH (e.g., for multiple UEs) and / or the aggregation level being used. Possible locations for the PDCCH (e.g., in time and / or frequency) may be referred to as PDCCH candidates, and the set of all possible PDCCH locations at the aggregation level may be referred to as the search space. For example, the set of all possible PDCCH locations for a specific UE may be referred to as the UE-specific search space. Similarly, the set of all possible PDCCH locations across all UEs may be referred to as the common search space. The set of all possible PDCCH locations for a specific group of UEs may be referred to as the group-wide search space. One or more search spaces across aggregation levels can be referred to as a set of search spaces (SS). CORESET 320 can be interleaved or non-interleaved. An interleaved CORESET 320 can have a CCE-to-REG mapping such that adjacent CCEs are mapped to discrete REG appendages in the frequency domain (e.g., adjacent CCEs are not mapped to consecutive REG appendages of the CORESET 320). A non-interleaved CORESET 320 can have a CCE-to-REG mapping such that all CCEs are mapped to consecutive REG appendages of the CORESET 320 (e.g., in the frequency domain). In some cases, as described in more detail below, UE 120 can be configured to perform PDCCH monitoring at a time slot level or at a multi-time slot level (e.g., in CORESET). As noted above, Figure 3 is provided as an example. Other examples may differ from those described with respect to Figure 3. Figure 4 is a schematic diagram illustrating an example 400 of PDCCH monitoring according to this disclosure. For applications with higher carrier frequencies (e.g., 52.6 GHz–114.25 GHz), for example, orthogonal frequency division multiplexing (OFDM) waveforms with large subcarrier spacing (e.g., 240 kHz–1.92 MHz) can be used to reduce phase noise and / or fill a large bandwidth (2 GHz). However, for example, due to the need for a large subcarrier spacing (SCS), the time slot length in such waveforms with high carrier frequencies can be short. For example, the time slot length in a frequency range 2 (FR2) waveform with a 120 kHz SCS can be 125 μs, while the time slot length in an FR2-2 waveform with a 960 kHz SCS can be 15.6 μsec. In some cases, the processing isochrona of UE 120 (e.g., for control and data processing) may not scale proportionally with the slot length. For example, a UE 120 using a lower frequency range (e.g., FR1 / FR2) may enjoy the power-saving benefits of microsleep. However, for a UE 120 using a higher frequency range (e.g., FR4), control channel processing may be comparable to or even exceed the slot length. Therefore, microsleep may not be possible. In another instance, a UE 120 using FR1 / FR2 can be configured to monitor the PDCCH in each slot. However, in FR4 (e.g., due to limited processing power), the minimum PDCCH monitoring periodicity may be greater than that of a single slot. Therefore, performing PDCCH monitoring in each slot may not be possible. In some cases, UE 120 can be configured to perform microsleep with or without time slot scheduling. As shown in the first example 405, UE 120 can perform PDCCH monitoring in the first three symbols of a time slot, and UE 120 can perform microsleep with time slot scheduling in the remaining 11 symbols. As shown in the second example 410, PDCCH monitoring and processing time may require half (or more) of the time slot time. Therefore, microsleep without time slot scheduling can be less than half the time slot length. In some cases, as described in more detail below, UE 120 can be configured to perform multi-time slot PDCCH monitoring. As noted above, Figure 4 is provided as an example. Other examples may differ from those described with respect to Figure 4. Figure 5 is a schematic diagram illustrating instances 500 and 510 of slot-based PDCCH monitoring according to this disclosure. In some cases, as shown in instance 500, a UE (such as UE 120) can be configured to perform PDCCH monitoring at each slot in a subframe. In some cases, as shown in Example 510, UE 120 can be configured to perform multi-slot PDCCH monitoring. For example, UE 120 can be configured to monitor the PDCCH every other slot or every few slots (instead of at every individual slot). In some cases, variables X can represent the length of the time slot group. For example, UE 120 can be configured to... PDCCH monitoring is performed at X time slots. Therefore, the PDCCH monitoring timing (MO) can be performed at each subframe. Occurs at X time slots. The supported values ​​of X can be at least partially based on one or more capabilities of UE 120, and network node 110 can configure one or more PDCCH search spaces for UE 120 at least partially based on UE 120 capability reports. In some cases, variables Y can be used to represent the monitoring span. The monitoring span can correspond to the number of consecutive time slots, where the monitoring opportunity lies within a time slot group. The monitoring opportunity can be confined within the monitoring span of the time slot group. For example, a monitoring span with one time slot can have... The value of Y=1, and the monitoring span with three consecutive time slots can have The value of Y=3. In some cases, for group (1) search space (SS) (e.g., type 1 common search space (CSS) and type 3 CSS, UE-specific SS with dedicated RRC configuration), one or more of the following may be supported: It is possible Within a time slot group of X time slots Monitoring SS within Y consecutive time slots; Y consecutive time slots can be located in Anywhere within a group of X time slots; exist Within a time slot group of X time slots The positions of Y consecutive time slots can be maintained across different time slot groups; and Blind decoding (BD) attempts for all groups (1) SS can be limited to falling into the same category. Within Y consecutive time slots. In some cases, for group (2) SS (e.g., type 1 CSS and type 0, 0A and 2 CSS without dedicated RRC configuration), the SS monitoring location can be Anywhere within a group of X time slots (with possible exceptions). In some cases, ( X, The supported combinations for Y) may be as follows: UE 120, capable of multi-slot monitoring, can (e.g., mandatorily) support: For SCS 480 kHz: ( X, Y) = (4, 1); and For SCS 960 kHz: ( X, Y) = (8, 1). The UE 120, capable of multi-slot monitoring, may (optionally) support: For SCS 480 kHz: ( X, Y) = (4, 2); and For SCS 960 kHz: ( X, Y) = (8,4), (4,2), (4,1). As described in more detail below, UE 120 can be configured to switch between one or more search space sets to perform multi-slot PDCCH monitoring. As noted above, Figure 5 is provided as an example. Other examples may differ from those described with respect to Figure 5. Figure 6 is a schematic diagram illustrating an example 600 of a search space set group switching according to this disclosure. In some cases, UE 120 may perform Search Space Set Group (SSSG) handover. As described herein, an SSSG can be a group of one or more search space sets. In some cases (e.g., in unauthorized band operations), network node 110 may begin transmitting control information and data only after acquiring a channel (e.g., via a Listen-Before-Speak (LBT) procedure). To have more frequent channel access opportunities (e.g., instead of waiting for the next PDCCH opportunity to begin transmitting and risking media loss), it may be desirable for network node 110 to configure UE 120 to perform more frequent control monitoring (e.g., every...). The time slot group of X time slots is more than once. During the Channel Occupied Time (COT) (e.g., after LBT success), UE 120 may not need to continue frequent control monitoring, and UE 120 can switch to sparse control monitoring (e.g., every M (>1) time slots once, for power saving. In some cases, multiple groups of search space sets (e.g., two groups) can be configured. For example, the search space set for UE 120 can be associated with either a first search space set group (SSSG#0) or a second search space set group (SSSG#1). In some cases, the search space set associated with SSSG#0 can correspond to a dense PDCCH MO (i.e., short search space set periodicity) and can be used outside the COT. In some cases, the search space set associated with SSSG#1 can correspond to a sparse PDCCH MO (i.e., long search space set periodicity) and can be used within the COT. In some cases, the switching mechanism between SSSG#0 and SSSG#1 can be explicit (e.g., bits of DCI format 2_0) or implicit (e.g., based on PDCCH decoding) with the aid of COT duration information and an automatic backoff timer. In some cases, the switching boundary may lie between a first search space group (e.g., SSSG#0) and a second search space group (e.g., SSSG#1). In some cases, for multi-slot PDCCH monitoring, the SSSG switching boundary may be aligned with the slot group boundary. For example, after an (explicit or implicit) SSSG switching indication, a new SSSG may begin at a first slot group located at least a certain number of symbols after the switching indication (e.g., as per P...). 切換 (As indicated) at the location. P 切換This can be a switching delay configured via RRC. In some cases, for multi-slot PDCCH monitoring, the SSSG switching boundary can be aligned with the slot boundary. For example, after an (explicit or implicit) SSSG switching indication, a new SSSG can begin at the first slot group, where the first slot is at least P of the switching indication. 切換 After a symbol. In some cases, The positioning of Y consecutive time slots can be maintained across one or more groups of time slots (time slot groups) within the SSSG. However, The positioning of Y consecutive time slots (e.g., monitoring span) can be changed at the boundaries of the SSSG switch. As shown in Example 600, the time slot group length can be four time slots, and the monitoring span can be a single time slot (e.g., ( X, Y) = (4, 1). In the first search space set group (SSSG#0), the monitoring span can be located in the third time slot of the time slot group. In contrast, in the second search space set group (SSSG#2), the monitoring span can be located in the first time slot of the time slot group. Therefore, the separation between the two monitoring spans is not at least X time slots. This may cause UE 120 to be unable to properly perform PDCCH monitoring during each monitoring span (e.g., at each monitoring moment in a monitoring time slot). For example, UE 120 may not be able to properly monitor and decode each PDCCH moment in a PDCCH moment (e.g., before the next PDCCH moment occurs), which may result in some information in the PDCCH being lost or not properly received by UE 120. This document describes techniques and apparatus for multi-slot PDCCH monitoring. In some cases, the UE can receive an instruction to perform PDCCH monitoring in a first monitoring span of a first set of time slots and in a second monitoring span of a second set of time slots. This instruction may indicate that the start of the first monitoring span should be at least a threshold number of time slots away from the start of the second monitoring span. For example, the instruction may indicate that the start of the first monitoring span should be at least a threshold number of time slots away from the start of the second monitoring span. X time slots. In some configurations, the indication may indicate that the position of the first monitoring span in the first set of time slots is the same as the position of the second monitoring span in the second set of time slots. In some configurations, the UE may abandon one or more monitoring opportunities in the first or second monitoring span at least in part based on the fact that the start of the first monitoring span and the start of the second monitoring span are less than a threshold number of time slots apart. In some configurations, the UE may adjust the boundary of the first SSSG or the boundary of the second SSSG such that the start of the first monitoring span and the start of the second monitoring span are separated by a number of time slots greater than or equal to the threshold number of time slots. The UE may selectively perform PDCCH monitoring in the first or second monitoring span at least in part based on the indication. In some cases, the first monitoring span and the second monitoring span can be separated from each other by less than a threshold number of time slots (e.g., X time slots). As mentioned above, this may cause the UE to be unable to properly perform PDCCH monitoring at every monitoring time slot within the monitoring span. Using the techniques and apparatus described herein, the UE can be configured to selectively perform PDCCH monitoring at least in part based on the location of the monitoring span. For example, if the monitoring spans are separated by at least a threshold number (e.g., If there are X time slots, the UE can receive an instruction to perform only PDCCH monitoring, or if the monitoring span is not at least a threshold number of time slots apart, the UE can forgo one or more monitoring opportunities or adjust the SSSG handover boundary. This may reduce the likelihood of another PDCCH occurring (e.g., monitoring opportunity) before the UE has had an opportunity to receive and properly obtain (e.g., decode) information from the currently monitored PDCCH. As noted above, Figure 6 is provided as an example. Other examples may differ from those described with respect to Figure 6. Figure 7 is a schematic diagram illustrating an example 700 of multi-slot PDCCH monitoring according to this disclosure. UE (such as UE 120) can communicate with network nodes (such as network node 110). As shown in component symbol 705, network node 110 can send an instruction to perform PDCCH monitoring at a first monitoring span in a first set of time slots and at a second monitoring span in a second set of time slots, and UE 120 can receive this instruction. The instruction may indicate that the start of the first monitoring span should be at least a threshold number of time slots away from the start of the second monitoring span. For example, network node 110 can send an instruction to UE 120 to perform PDCCH monitoring at one or more monitoring times in the first monitoring span (in the first set of time slots) and at one or more monitoring times in the second monitoring span (in the second set of time slots), wherein the second monitoring span is at least a threshold number of time slots away from the first monitoring span. X time slots. As described in this article, the variables... X (e.g., the number of time slot thresholds) can correspond to the length of the time slot group. For example, UE 120 can be configured to... PDCCH monitoring is performed at X time slots. Variables Y can correspond to the monitoring span, which can be the number of consecutive time slots, where the monitoring time is within the time slot group. As shown in conjunction with element symbol 710, network node 110 and UE 120 can transmit information associated with UE 120 performing PDCCH monitoring. In some configurations, the information can be received as part of an instruction to perform PDCCH monitoring (as described in conjunction with element symbol 705). In some configurations, the information can be received separately from the instruction to perform PDCCH monitoring. In some configurations, the information may include PDCCH monitoring limitation information. This information may indicate that the position of the monitoring span in the first set of time slots should be the same as the position of the monitoring span in the second set of time slots. Therefore, the first monitoring span may be at least a threshold number of time slots away from the second monitoring span. Additional details regarding the PDCCH monitoring limitation information are described below with reference to Figures 8A and 8B. In some configurations, the information may include monitoring span rule abandonment information. In some configurations, UE 120 may be configured to abandon all monitoring opportunities for a time slot group. For example, if the start of a monitoring span of a time slot group (e.g., the initial monitoring opportunity of the monitoring span) is not at least a threshold number of time slots away from the start of a monitoring span of another time slot group (e.g., a previous time slot group), then UE 120 may be configured to abandon all monitoring opportunities for the time slot group. In some configurations, UE 120 may be configured to abandon a single monitoring opportunity for a time slot group, such that the start of the monitoring span is at least a threshold number of time slots away from the start of another (previous) monitoring span. Additional details regarding monitoring span rule abandonment information are described below with reference to Figures 9A and 9B. In some configurations, the information may include SSSG handover boundary adjustment information. UE 120 may determine that the monitoring span of the first set of time slots (associated with SSSG#0) is not at least a threshold number of time slots apart from the monitoring span of the second set of time slots (associated with SSSG#1). UE 120 may be configured to adjust the SSSG handover boundary such that the monitoring span associated with SSSG#0 and the monitoring span associated with SSSG#1 are at least a threshold number of time slots apart. Additional details regarding the SSSG handover boundary adjustment information are described below with reference to Figures 10A and 10B. As shown in component symbol 715, UE 120 can selectively perform PDCCH monitoring. In some cases, as described above, UE 120 can perform PDCCH monitoring at one or more monitoring times within a time slot group. In one example (described in Figures 8A and 8B), UE 120 can perform PDCCH monitoring at both the monitoring times in the first time slot group and the monitoring times in the second time slot group, provided that the monitoring span in the first time slot group has the same position as the monitoring span in the second time slot group. In another example (described in Figures 9A and 9B), if the monitoring span is not at least a threshold number of time slots away from another monitoring span, UE 120 can abandon one or more monitoring times for the monitoring span, and UE 120 can perform PDCCH monitoring at one or more remaining monitoring times. In another instance (as described in Figures 10A and 10B), UE 120 can adjust the SSSG handover boundary such that the monitoring span associated with one SSSG and the monitoring span associated with another SSSG are at least a threshold number of time slots apart. As mentioned above, the first monitoring span and the second monitoring span can be separated from each other by less than a threshold number of time slots (e.g., X time slots). This may cause UE 120 to be unable to properly perform PDCCH monitoring at every monitoring time slot within the monitoring span. Using the techniques and apparatus described herein, UE 120 can be configured to selectively perform PDCCH monitoring at least in part based on the location of the monitoring span. For example, if the monitoring spans are separated by at least a threshold number (e.g., If there are X time slots, UE 120 can receive an instruction to perform only PDCCH monitoring, or if the monitoring span is not at least a threshold number of time slots apart, UE 120 can forgo one or more monitoring opportunities or adjust the SSSG handover boundary. This may reduce the likelihood of another PDCCH occurring (e.g., monitoring opportunity) before UE 120 has had an opportunity to receive and properly obtain (e.g., decode) information from the currently monitored PDCCH. As noted above, Figure 7 is provided as an example. Other examples may differ from those described with respect to Figure 7. Figures 8A and 8B are schematic diagrams illustrating example 800 of PDCCH monitoring restrictions according to this disclosure. As described above with reference to component symbol 710 in Example 700, network node 110 can send information associated with UE 120 performing PDCCH monitoring, and UE 120 can receive this information. In some cases, the information (e.g., configuration information) can indicate that the position of the monitoring span in the first set of time slots should be the same as the position of the monitoring span in the second set of time slots. Therefore, the PDCCH monitoring timing of the entire search space set can be restricted to fall into the same monitoring span (e.g., consecutive). In Y time slots. In this example, the variable X can be four time slots, and the variables are... Y can be a time slot (e.g., ( X, Y) = (4, 1)). In some configurations, the information may indicate that the first monitoring span should be located at a specific time slot of the first set of time slots, and the second monitoring span should be located at a specific time slot of the second set of time slots. For example, the specific time slot of the first set of time slots could be the first time slot of the first set of time slots, and the specific time slot of the second set of time slots could be the first time slot of the second set of time slots. In another instance, the specific time slot of the first set of time slots could be the third time slot of the first set of time slots, and the specific time slot of the second set of time slots could be the third time slot of the second set of time slots. As shown in Example 800, information can indicate that a first monitoring span should be located at the first time slot of a first set of time slots, and a second monitoring span should be located at the first time slot of a second set of time slots. Therefore, the first monitoring span will be at least a threshold number of time slots away from the second monitoring span. For example, at the SSSG switching boundary, the start of the monitoring span of the first set of time slots (associated with SSSG#0) can be at least a threshold number of time slots away from the start of the monitoring span of the second set of time slots (associated with SSSG#1). X time slots (e.g., 4 time slots). As noted above, Figures 8A and 8B are provided as examples. Other examples may differ from those described with respect to Figures 8A and 8B. Figures 9A and 9B are schematic diagrams illustrating an example 900 of the abandonment of the monitoring span rule according to this disclosure. As described above with reference to component symbol 710 in Example 700, network node 110 can send information associated with UE 120 performing PDCCH monitoring, and UE 120 can receive this information. In some cases, if the monitoring span is not at least [missing information] from another monitoring span in a subframe (e.g., a previous monitoring span), With X time slots, the information can be used to instruct UE 120 to abandon one or more monitoring opportunities across the monitoring span. In this example, the variables... X can be four time slots, and the variables are... Y can be two time slots (e.g., ( X, Y) = (4, 2). Moreover, in this example, the SSSG switching boundary can be aligned with the time slot group boundary. As shown in Example 900, the first set of time slots associated with SSSG#0 may include monitoring spans (e.g., two monitoring times) at the second and third time slots of the time slot group. The second set of time slots associated with SSSG#1 may include monitoring spans (e.g., two monitoring times) at the first and second time slots of the time slot group. The start of the monitoring span of the first set of time slots (e.g., the second time slot of the first set of time slots) may be not at least four time slots away from the start of the monitoring span of the second set of time slots (e.g., the first time slot of the second set of time slots). Conversely, the monitoring span of the first set of time slots may be only three time slots away from the monitoring span of the second set of time slots. In some configurations, UE 120 can be configured to abandon all monitoring opportunities for a time slot group. For example, if the start of the monitoring span of a time slot group (e.g., the initial monitoring opportunity of the monitoring span) is not at least a threshold number of time slots away from the start of the monitoring span of another time slot group (e.g., a previous time slot group), then UE 120 can be configured to abandon all monitoring opportunities for the time slot group. In this example, UE 120 can determine that the first time slot of the second time slot group is not at least four time slots away from the second time slot of the first time slot group. Therefore, UE 120 can abandon the entire monitoring span of the second time slot group (e.g., the monitoring opportunity at the first time slot of the second time slot group and the monitoring opportunity at the second time slot of the second time slot group). UE 120 can perform PDCCH monitoring at the next monitoring opportunity, which may be associated with a third time slot group. In some configurations, UE 120 can be configured to relinquish a separate monitoring opportunity for a time slot group. For example, if the start of a monitoring span including a time slot group and the start of another monitoring span associated with another time slot group (e.g., a previous time slot group) are not at least a threshold number of time slots apart, UE 120 can be configured to relinquish that monitoring opportunity. In this example, UE 120 can determine that the first time slot of the second time slot group (e.g., the start of the second monitoring span) is not at least four time slots apart from the second time slot of the first time slot group (e.g., the start of the first monitoring span). Therefore, UE 120 can relinquish the first time slot of the second time slot group. Because the second time slot of the second time slot group is four time slots apart from the second time slot of the first time slot group, UE 120 can choose not to relinquish the second time slot of the second time slot group. Therefore, UE 120 can perform PDCCH monitoring at the second time slot of the second time slot group. As noted above, Figures 9A and 9B are provided as examples. Other examples may differ from those described with respect to Figures 9A and 9B. Figures 10A and 10B are schematic diagrams illustrating an example 1000 of SSSG switching boundary adjustment according to this disclosure. As described above with reference to component symbol 710 in example 700, network node 110 can send information associated with UE 120 performing PDCCH monitoring, and UE 120 can receive this information. In some cases, the information can indicate adjustments to the SSSG handover boundary for UE 120. In this example, variables X can be four time slots, and the variables are... Y can be two time slots (e.g., ( X, Y) = (4, 2). As shown in Example 1000, the first set of time slots associated with SSSG#0 may include a first monitoring span having monitoring opportunities at the second and third time slots of the time slot group. The second set of time slots associated with SSSG#1 may include a second monitoring span having monitoring opportunities at the first and second time slots of the time slot group. Therefore, the start of the first monitoring span may not be at least four time slots away from the start of the second monitoring span. Conversely, the start of the first monitoring span may be only three time slots away from the start of the second monitoring span. In some configurations, UE 120 can be configured to adjust one or more SSSG handover boundaries. For example, UE 120 can determine that the start of a first monitoring span associated with SSSG#0 and the start of a second monitoring span associated with SSSG#1 are not at least a threshold number of time slots apart. UE 120 can be configured to adjust the SSSG handover boundaries such that the start of the monitoring span associated with SSSG#0 and the start of the monitoring span associated with SSSG#1 are at least a threshold number of time slots apart. For example, UE 120 can adjust the monitoring span of SSSG#1 such that the first monitoring timing of SSSG#1 occurs at the second time slot in the second group of time slots. Therefore, the monitoring span associated with SSSG#1 may only include the monitoring timing at the second time slot in the second group of time slots. In some configurations, UE 120 can be configured to perform one or more of the following to adjust the SSSG handover boundary. In the first step, UE 120 can be configured to determine the SSSG handover boundary based at least in part on traditional rules. For example, UE 120 can be configured to base at least in part on P 切換(As described herein) to determine the SSSG handover boundary. The SSSG handover boundary can be aligned with a time slot group boundary or with a single time slot boundary. In the second step, UE 120 can be configured to identify the location (e.g., position) of the last monitored span before the SSSG handover boundary. In the third step, if the location of the last monitored span is less than the SSSG handover boundary... If X time slots are used, then UE 120 can be configured to adjust (e.g., push) the handover boundary to be at least [distance] from the start of the monitoring span. The time slot boundaries of X time slots. As noted above, Figures 10A and 10B are provided as examples. Other examples may differ from those described with respect to Figures 10A and 10B. Figure 11 is a schematic diagram illustrating an example procedure 1100 performed by a UE, for example, according to this disclosure. Example procedure 1100 is an instance in which a UE (e.g., UE 120) performs operations associated with multi-slot PDCCH monitoring. As shown in Figure 11, in some configurations, process 1100 may include receiving an instruction to perform PDCCH monitoring in a first monitoring span of a first set of time slots and in a second monitoring span of a second set of time slots, wherein the start of the first monitoring span is at least a threshold number of time slots away from the start of the second monitoring span (block 1110). For example, a UE (e.g., using communication manager 140 and / or receiving unit 1302 depicted in Figure 13) may receive an instruction to perform PDCCH monitoring in a first monitoring span of a first set of time slots and in a second monitoring span of a second set of time slots, wherein the start of the first monitoring span is at least a threshold number of time slots away from the start of the second monitoring span (as described above). As further shown in Figure 11, in some cases, process 1100 may include selectively performing PDCCH monitoring in a first monitoring span or a second monitoring span, at least in part based on an instruction (block 1120). For example, the UE (e.g., using communication manager 140 and / or monitoring component 1308 depicted in Figure 13) may selectively perform PDCCH monitoring in a first monitoring span or a second monitoring span, at least in part based on an instruction (as described above). Process 1100 may include additional states, such as any single state or any combination of states, as described below and / or in conjunction with one or more other processes described elsewhere herein. In the first state, the indication is used to indicate that the position of the first monitoring span in the first set of time slots is the same as the position of the second monitoring span in the second set of time slots. In the second state sample, either alone or in combination with the first state sample, each of the first and second monitoring spans includes multiple monitoring opportunities, each of the monitoring opportunities having a duration less than the duration of the time slot. In the third state sample, the number of monitoring opportunities in the first monitoring span is equal to the number of monitoring opportunities in the second monitoring span, either alone or in combination with one or more of the first and second state samples. In the fourth state sample, selectively performing PDCCH monitoring in the first or second monitoring span, either alone or in combination with one or more of the first to third state samples, includes performing PDCCH monitoring in the first and second monitoring spans at least in part based on the number of time slots in which the start of the first and second monitoring spans are separated by a number of time slots greater than or equal to a threshold number. In the fifth state sample, either alone or in combination with one or more of the first to fourth state samples, the first set of time slots is associated with the first SSSG, and the second set of time slots is associated with the second SSSG, wherein the switching boundary between the first SSSG and the second SSSG is aligned with the boundary between the first set of time slots and the second set of time slots. In the sixth state sample, either alone or in combination with one or more of the first to fifth state samples, process 1100 includes: determining that the start of the first monitoring span is at least a threshold number of time slots away from the start of the second monitoring span. In the seventh state sample, either alone or in combination with one or more of the first to sixth state samples, process 1100 includes: abandoning a monitoring opportunity in the first monitoring span or the second monitoring span based at least in part on the fact that the start of the first monitoring span is less than a threshold number of time slots from the start of the second monitoring span. In the eighth state sample, either alone or in combination with one or more of the first to seventh state samples, process 1100 includes: at least in part abandoning all monitoring opportunities in the first monitoring span or the second monitoring span based on the fact that the start of the first monitoring span is less than a threshold number of time slots from the start of the second monitoring span. In the ninth state sample, selectively performing PDCCH monitoring in the first or second monitoring span, either alone or in combination with one or more of the first to eighth state samples, includes: deciding not to perform PDCCH monitoring in the first or second monitoring span based at least in part on the fact that the start of the first monitoring span is less than a threshold number of time slots from the start of the second monitoring span. In the tenth state sample, either alone or in combination with one or more of the first to ninth state samples, process 1100 includes: adjusting the boundary of the first SSSG or the boundary of the second SSSG such that the start of the first monitoring span and the start of the second monitoring span are separated by a number of time slots greater than or equal to the number of time slots of the threshold. In the eleventh state sample, selectively performing PDCCH monitoring in the first or second monitoring span, either alone or in combination with one or more of the first to tenth state samples, includes performing PDCCH monitoring in the first and second monitoring spans based at least in part on the adjusted boundary of the first SSSG or the adjusted boundary of the second SSSG. In the twelfth state sample, either alone or in combination with one or more of the first to eleventh state samples, process 1100 includes: identifying the starting position of the first monitoring span, determining that the starting position of the first monitoring span is less than a threshold number of time slots away from the switching boundary, and adjusting the boundary of the first SSSG at least in part based on determining that the starting position of the first monitoring span is less than a threshold number of time slots away from the switching boundary. Although Figure 11 illustrates an example block of process 1100, in some versions, process 1100 may include additional blocks, fewer blocks, different blocks, or blocks with different arrangements compared to the blocks depicted in Figure 11. Alternatively or concurrently, two or more blocks of process 1100 may be executed concurrently. Figure 12 is a schematic diagram illustrating an example process 1200 performed by a network node, for example, according to this disclosure. Example process 1200 is an instance in which a network node (e.g., network node 110) performs operations associated with multi-slot PDCCH monitoring. As shown in Figure 12, in some configurations, process 1200 may include sending an instruction to perform PDCCH monitoring in a first monitoring span of a first set of time slots and in a second monitoring span of a second set of time slots, wherein the start of the first monitoring span is at least a threshold number of time slots away from the start of the second monitoring span (block 1210). For example, a network node (e.g., using communication manager 150 and / or transmitting component 1404 depicted in Figure 14) may send an instruction to perform PDCCH monitoring in a first monitoring span of a first set of time slots and in a second monitoring span of a second set of time slots, wherein the start of the first monitoring span is at least a threshold number of time slots away from the start of the second monitoring span (as described above). Process 1200 may include additional patterns, such as any single pattern or any combination of patterns, as described below and / or in conjunction with one or more other processes described elsewhere herein. Although Figure 12 illustrates an example block of process 1200, in some versions, process 1200 may include additional blocks, fewer blocks, different blocks, or blocks with different arrangements compared to the blocks depicted in Figure 12. Alternatively or concurrently, two or more blocks of process 1200 may be executed simultaneously. Figure 13 is a schematic diagram of an example device 1300 for wireless communication. Device 1300 may be a UE, or a UE may include device 1300. In some embodiments, device 1300 includes a receiving component 1302 and a transmitting component 1304, which can communicate with each other (e.g., via one or more buses and / or one or more other components).

Alternatively or additionally, one or more components shown in Figure 13 may be implemented within one or more components described in conjunction with Figure 2. Alternatively or additionally, one or more components in the set of components may be at least partially implemented as software stored in memory. For example, a component (or a portion of a component) may be implemented as instructions or code stored in a non-transitory computer-readable medium and executable by a controller or processor to perform the function or operation of the component. The receiving unit 1302 can receive communications from the device 1306, such as reference signals, control information, data communications, or combinations thereof. The receiving unit 1302 can provide the received communications to one or more other components of the device 1300. In some embodiments, the receiving unit 1302 can perform signal processing on the received communications (such as filtering, amplification, demodulation, analog-to-digital conversion, demultiplexing, deinterleaving, demapping, equalization, interference cancellation, or decoding, etc.) and can provide the processed signals to one or more other components of the device 1300. In some embodiments, the receiving unit 1302 may include one or more antennas, modems, demodulators, MIMO detectors, receiver processors, controllers / processors, memory, or combinations thereof, as described in conjunction with FIG. 2. Transmitting component 1304 can transmit communications, such as reference signals, control information, data communications, or combinations thereof, to device 1306. In some embodiments, one or more other components of device 1300 can generate communications and provide the generated communications to transmitting component 1304 for transmission to device 1306. In some embodiments, transmitting component 1304 can perform signal processing (such as filtering, amplification, modulation, digital-to-analog conversion, multiplexing, interleaving, mapping, or encoding) on ​​the generated communications and can transmit the processed signals to device 1306. In some embodiments, transmitting component 1304 may include one or more antennas, modems, modulators, transmit MIMO processors, transmit processors, controllers / processors, memory, or combinations thereof, as described in conjunction with FIG. 2. In some embodiments, transmitting component 1304 may be co-located with receiving component 1302 in a transceiver. The receiving unit 1302 can receive instructions to perform PDCCH monitoring in a first monitoring span of a first set of time slots and in a second monitoring span of a second set of time slots, wherein the start of the first monitoring span is at least a threshold number of time slots away from the start of the second monitoring span. The monitoring unit 1308 can selectively perform PDCCH monitoring in the first monitoring span or the second monitoring span, at least in part, based on the instructions.

The abandonment component 1312 can abandon all monitoring opportunities in the first or second monitoring span, at least in part, based on the fact that the start of the first monitoring span and the start of the second monitoring span are less than a threshold number of time slots apart. The adjustment component 1314 can adjust the boundary of the first SSSG or the boundary of the second SSSG, such that the start of the first monitoring span and the start of the second monitoring span are separated by a number of time slots greater than or equal to the threshold number of time slots. The determining component 1310 can identify the starting position of the first monitoring span. The determining component 1310 can determine that the starting position of the first monitoring span is less than a threshold number of time slots away from the switching boundary. The adjusting component 1314 can adjust the boundary of the first SSSG at least in part based on the determination that the starting position of the first monitoring span is less than a threshold number of time slots away from the switching boundary. The number and arrangement of components shown in Figure 13 are provided as examples. In practice, there may be additional components, fewer components, different components, or components with different arrangements compared to those shown in Figure 13. Furthermore, two or more components shown in Figure 13 may be implemented within a single component, or a single component shown in Figure 13 may be implemented as multiple, distributed components. Additionally or alternatively, a set of (one or more) components shown in Figure 13 may perform one or more functions described as being performed by another set of components shown in Figure 13. Figure 14 is a schematic diagram of an example device 1400 for wireless communication. Device 1400 may be a network node, or a network node may include device 1400. In some embodiments, device 1400 includes a receiving component 1402 and a transmitting component 1404, which can communicate with each other (e.g., via one or more buses and / or one or more other components). As shown, device 1400 can use the receiving component 1402 and the transmitting component 1404 to communicate with another device 1406 (such as a UE, a network node, or another wireless communication device).

Alternatively or additionally, device 1400 may be configured to perform one or more processes described herein, such as process 1200 of Figure 12. In some embodiments, device 1400 and / or one or more components shown in Figure 14 may include one or more components of a network node described in conjunction with Figure 2. Alternatively or additionally, one or more components shown in Figure 14 may be implemented within one or more components described in conjunction with Figure 2.

Configuration component 1408 can send configuration information, such as the configuration information described above in conjunction with component symbol 710 in Figure 7. The number and arrangement of components shown in Figure 14 are provided as examples. In practice, there may be additional components, fewer components, different components, or components with different arrangements compared to those shown in Figure 14. Furthermore, two or more components shown in Figure 14 may be implemented within a single component, or a single component shown in Figure 14 may be implemented as multiple, distributed components. Additionally or alternatively, a set of (one or more) components shown in Figure 14 may perform one or more functions described as being performed by another set of components shown in Figure 14. Communication systems (such as 5G NR systems) can be deployed in various ways, with a variety of components or parts. In a 5G NR system or network, network nodes, network entities, network mobility elements, RAN nodes, core network nodes, network elements, base stations, or network equipment can be implemented in aggregated or deaggregated architectures. For example, a base station (such as a Node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP, or a cell, etc.) or one or more units (or one or more components) performing base station functionality can be implemented as an aggregated base station (also referred to as a standalone base station or a monolithic base station) or a deaggregated base station. A "network entity" or "network node" can refer to a deaggregated base station or one or more units of a deaggregated base station (such as one or more CUs, one or more DUs, one or more RUs, or combinations thereof). Aggregated base stations (e.g., aggregated network nodes) can be configured to utilize radio protocol stacks that are physically or logically integrated within a single RAN node (e.g., within a single device or unit). Deaggregated base stations (e.g., deaggregated network nodes) can be configured to utilize protocol stacks that are physically or logically distributed among two or more units (e.g., one or more CUs, one or more DUs, or one or more RUs). In some instances, the CU can be implemented within a network node, and one or more DUs can be co-located with the CU, or alternatively, can be geographically or virtually distributed across one or more other network nodes. The DU can be implemented to communicate with one or more RUs. Each of the CU, DU, and RU can also be implemented as a virtual unit, such as a Virtual Central Unit (VCU), Virtual Distributed Unit (VDU), or Virtual Radio Unit (VRU), etc. Base station type operation or network design can consider the aggregation characteristics of base station functionality. For example, de-aggregated base stations can be used in IAB networks, Open Radio Access Networks (O-RAN (such as network configurations initiated by the O-RAN Alliance)), or Virtualized Radio Access Networks (vRAN, also known as Cloud Radio Access Networks (C-RAN)) to facilitate the scaling of communication systems by dividing base station functionality into one or more units that can be deployed individually. De-aggregated base stations can include functionality implemented by two or more units across various physical locations, as well as functionality virtually implemented for at least one unit, which enables flexibility in network design. The individual units of a de-aggregated base station can be configured for wired or wireless communication with at least one other unit of the de-aggregated base station. Figure 15 is a schematic diagram illustrating an example deconverged base station architecture 1500 according to this disclosure. The deconverged base station architecture 1500 may include a CU 1510, which may communicate directly with the core network 1520 via a backhaul link, or indirectly with the core network 1520 via one or more deconverged control units (such as a near-RT RIC 1525 (via an E2 link), or a non-RT RIC 1515 associated with a Service Management and Orchestration (SMO) framework 1505, or both). The CU 1510 may communicate with one or more DUs 1530 via a corresponding midhaul link (such as via an F1 interface). Each DU in the DUs 1530 may communicate with one or more RUs 1540 via a corresponding fronthaul link. Each RU in the RUs 1540 may communicate with one or more UEs 120 via a corresponding radio frequency (RF) access link. In some implementations, UE 120 can be served by multiple RU 1540s simultaneously. Each unit (including CU 1510, DU 1530, RU 1540, and near-RT RIC 1525, non-RT RIC 1515, and SMO frame 1505) may include one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via wired or wireless transmission media, or coupled to such interfaces. Each element in the unit, or an associated processor or controller providing instructions to one or more communication interfaces of the corresponding unit, may be configured to communicate with one or more other units via transmission media. In some instances, each unit may include: a wired interface configured to receive signals on a wired transmission media or transmit signals on a wired transmission media to one or more other units; and a wireless interface that may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive signals on a wireless transmission media or transmit signals on a wireless transmission media to one or more other units, or both receive and transmit signals on a wireless transmission media. In some implementations, the CU 1510 can handle one or more higher-level control functions. These control functions may include Radio Resource Control (RRC) functions, Packet Data Convergence Protocol (PDCP) functions, or Service Data Adaptation Protocol (SDAP) functions, etc. Each control function can be implemented using an interface configured to transmit signals to other control functions handled by the CU 1510. The CU 1510 can be configured to handle user plane functions (e.g., Central Unit-User Plane (CU-PU) functions), control plane functions (e.g., Central Unit-Control Plane (CU-CP) functions), or combinations thereof. In some implementations, the CU 1510 can be logically separated into one or more CU-UP units and one or more CU-CP units. The CU-UP units can communicate bidirectionally with the CU-CP units via an interface (such as an E1 interface, when implemented in an O-RAN configuration). The CU 1510 can be implemented to communicate with the DU 1530 (if necessary) for network control and signal transmission. Each DU 1530 may correspond to a logic unit that includes one or more base station functions to control the operation of one or more RU 1540s. In some configurations, at least in part depending on functional separation (such as functional separation defined by 3GPP), the DU 1530 may be responsible for one or more of the Radio Link Control (RLC) layer, MAC layer, and one or more high-PHY layers. In some configurations, the one or more high-PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, and modulation and demodulation, etc. In some configurations, the DU 1530 may also be responsible for one or more low-PHY layers, such as by one or more modules for Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, or Physical Random Access Channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) can be implemented using an interface configured to transmit signals to other layers (and modules) handled by the DU 1530 or to control functions handled by the CU 1510. Each RU 1540 can implement lower-layer functionality. In some deployments, the RU 1540 controlled by the DU 1530 can correspond to a logical node responsible for RF processing functions or low-PHY layer functions (such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering) based on function separation such as lower-layer function separation (e.g., function separation defined by 3GPP). In this architecture, each RU 1540 can be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some implementations, the real-time and non-real-time modes of control and user plane communications with the RU 1540 can be controlled by the corresponding DU 1530. In some scenarios, this configuration allows each DU 1530 and CU 1510 to be implemented in a cloud-based RAN architecture (such as vRAN architecture). The SMO framework 1505 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 1505 can be configured to support the deployment of dedicated entity resources for RAN coverage requirements, which can be managed via an operation and maintenance interface (such as the O1 interface). For virtualized network elements, the SMO framework 1505 can be configured to interact with a cloud computing platform (such as the Open Cloud (O Cloud) platform 1590) via a cloud computing platform interface (such as the O2 interface) to perform network element lifecycle management (such as creating entities for virtualized network elements). Such virtualized network elements may include, but are not limited to: CU 1510, DU 1530, RU 1540, non-RT RIC 1515, and near-RT RIC 1525. In some implementations, the SMO framework 1505 can communicate with the hardware configuration of the 4G RAN (such as an open eNB (O-eNB) 1511) via an O1 interface. Alternatively, in some implementations, the SMO framework 1505 can communicate directly with each of one or more RUs 1540 via a corresponding O1 interface. The SMO framework 1505 may also include a non-RT RIC 1515 configured to support the functionality of the SMO framework 1505. The non-RT RIC 1515 can be configured to include logic functions for non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updates, or policy-based guidance for applications / features in the near-RT RIC 1525. The non-RT RIC 1515 can be coupled to or communicate with the near-RT RIC 1525 (e.g., via the A1 interface). The near-RT RIC 1525 can be configured to include logic functions for near-real-time control and optimization of RAN elements and resources via data collection and actions on interfaces (e.g., via the E2 interface) that connect one or more CU 1510s, one or more DU 1530s, or both, and O-eNBs to the near-RT RIC 1525. In some implementations, to generate AI / ML modules to be deployed in the near-RT RIC 1525, the non-RT RIC 1515 can receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 1525 and can be received from non-network data sources or network functions at the SMO framework 1505 or the non-RT RIC 1515. In some instances, the non-RT RIC 1515 or near-RT RIC 1525 can be configured to tune RAN behavior or performance. For example, the non-RT RIC 1515 can monitor long-term trends and patterns in performance and perform corrective actions using AI / ML models via the SMO framework 1505 (e.g., reconfiguration via the O1 interface) or via the establishment of RAN management policies (e.g., A1 interface policies).
