[0030] The present disclosure describes a method and apparatus for determining a physical downlink control channel (PDCCH) search space monitoring configuration for a wireless device, the user equipment specifying PDCCH monitoring for a subcarrier spacing (SCS) selected from a group of subcarrier spacings (SCSs), which are associated with spectrum above 52.6 GHz in 5G New Radio (NR). In one embodiment, monitoring restrictions associated with each of these SCSs are applied to each time slot of each CC, including the number of blind decodings (BD) and the number of CCEs for each component carrier (CC), and the user equipment (UE) decoding complexity associated with performing monitoring restrictions for different SCSs in the group is equal. In one embodiment, the monitoring restrictions for SCSs are scaled versions of each other and increase based on a reduction in symbol size (i.e., an increase in subcarrier spacing). In one embodiment, these monitoring restrictions associated with each of these SCSs are for a time slot group of multiple time slots and are for application within the duration of the time slot group.

[0031] However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other instances, well-known components, structures, and techniques have not been shown in detail to avoid obscuring the understanding of this description.

[0032] Reference to "some embodiments" or "embodiments" in this specification means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The phrase "in some embodiments" appearing in various places in this specification does not necessarily refer to the same embodiment.

[0033] In the following description and claims, the terms "coupled" and "connected" and their derivatives may be used. It should be understood that these terms are not intended to be synonymous with each other. "Coupled" is used to indicate that two or more elements that may or may not be in direct physical or electrical contact with each other cooperate or interact with each other. "Connected" is used to indicate the establishment of communication between two or more elements that are coupled to each other.

[0034] The processes shown in the following figures are performed by processing logic, which includes hardware (e.g., circuits, dedicated logic, etc.), software (such as software running on a general-purpose computer system or a dedicated machine), or a combination of both. Although the following describes these processes as certain sequential operations, it should be understood that certain operations described may be performed in a different order. In addition, certain operations may also be performed in parallel rather than in sequence.

[0035] The terms "server," "client," and "device" are intended to refer generally to data processing systems rather than specifically to a particular form factor of a server, client, and / or device.

[0036] The present disclosure describes a method and apparatus for determining a physical downlink control channel (PDCCH) search space monitoring configuration for a wireless device, the wireless device specifying PDCCH monitoring for a subcarrier spacing (SCS) selected from a group of subcarrier spacings (SCSs), which are associated with spectrum above 52.6 GHz in 5G New Radio (NR). In one embodiment, monitoring restrictions associated with each of these SCSs are applied to each time slot of each CC, including the number of blind decodings (BD) and the number of CCEs for each component carrier (CC), and the user equipment (UE) decoding complexity associated with performing monitoring restrictions for different SCSs in the group is equal. In one embodiment, the monitoring restrictions for SCSs are scaled versions of each other and increase based on the reduction of symbol size. In one embodiment, these monitoring restrictions associated with each of these SCSs are for a time slot group of multiple time slots and are for application within the duration of the time slot group.

[0037] Frequency bands used for 5G networks appear in two sets - Frequency Range 1 (FR1) and Frequency Range 2 (FR2). FR1 covers communications from 450MHz to 6GHz, which includes the LTE frequency range. FR2 covers 24.25GHz to 52.6GHz. FR2 is known as millimeter wave (mmWave) spectrum. In some embodiments, UEs and base stations can communicate via NR (also known as NR-U) in an unlicensed band higher than FR2.

[0038] In some embodiments, 5G NR operates into the 5G network in a spectrum above the 52.6 GHz band (e.g., a frequency greater than 52.6 GHz, such as between 52.6 GHz and 71 GHz). The radio waves in this band have wavelengths in the so-called millimeter band, and the radiation in this band is called millimeter waves. When operating at these frequencies, 5G NR implements both uplink and downlink operations in unlicensed and / or licensed bands and supports features such as, but not limited to, wideband carriers, flexible parameter sets, dynamic TDD, beamforming, and dynamic scheduling / HARQ timing.

[0039] It should be understood that aspects described in this disclosure with respect to NR may also be applicable to NR in spectrum above the 52.6 GHz band, unless the context indicates otherwise.

[0040] Figure 1 A simplified exemplary wireless communication system according to some embodiments is shown. Note that Figure 1 The system is only one example of possible systems, and features of the present disclosure may be implemented in any of a variety of systems as desired.

[0041] As shown, the exemplary wireless communication system includes a base station 102A, which communicates with one or more user equipment 106A, user equipment 106B to user equipment 106N, etc. through a transmission medium. Each of the user equipments may be referred to as a "user equipment" (UE) in this document. Therefore, the user equipment 106 is referred to as a UE or a UE device.

[0042] The base station (BS) 102A may be a base transceiver station (BTS) or a cell site ("cellular base station") and may include hardware that enables wireless communications with the UEs 106A through 106N.

[0043] The communication area (or coverage area) of a base station may be referred to as a "cell". The base station 102A and the UE 106 may be configured to communicate over a transmission medium using any of a variety of radio access technologies (RATs), which are also referred to as wireless communication technologies or telecommunication standards, such as GSM, UMTS (associated with, for example, WCDMA or TD-SCDMA air interfaces), LTE, Advanced LTE (LTE-A), 5G New Radio (5G-NR), HSPA, 3GPP2CDMA2000 (e.g., 1xRTT, 1xEV-DO, HRPD, eHRPD), and the like. Note that if the base station 102A is implemented in the context of LTE, it may alternatively be referred to as an "eNodeB" or "eNB". Note that if the base station 102A is implemented in the context of 5G NR, it may alternatively be referred to as a "gNodeB" or "gNB".

[0044] As shown, base station 102A may also be configured to communicate with network 100 (e.g., a core network of a cellular service provider, a telecommunications network such as a public switched telephone network (PSTN), and / or the Internet, among other possibilities). Thus, base station 102A may facilitate communications between user devices and / or between user devices and network 100. In particular, cellular base station 102A may provide UE 106 with various communication capabilities, such as voice, SMS, and / or data services.

[0045] Base station 102A and other similar base stations (such as base stations 102B...102N) operating according to the same or different cellular communication standards can therefore provide a network as a cell that can provide continuous or nearly continuous overlapping service to UE 106A to UE 106N and similar devices over a geographic area via one or more cellular communication standards.

[0046] Thus, although base station 102A may function as Figure 1 106A-N, each UE 106 may also be capable of receiving signals from (and possibly within communication range of) one or more other cells (which may be provided by base stations 102B-N and / or any other base stations), which may be referred to as "neighboring cells." Such cells may also be capable of facilitating communications between user devices and / or between user devices and network 100. Such cells may include "macro" cells, "micro" cells, "pico" cells, and / or cells of any other variety of granularity of service area size. For example, in Figure 1 The base stations 102A-102B shown in FIG. 1 may be macro cells, while the base station 102N may be a micro cell. Other configurations are also possible.

[0047] In some embodiments, base station 102A may be a next generation base station, such as a 5G New Radio (5G NR) base station or "gNB". In some embodiments, the gNB may be connected to a legacy evolved packet core (EPC) network and / or to an NR core (NRC) network. In addition, a gNB cell may include one or more transition and reception points (TRPs). In addition, a UE capable of operating in accordance with 5G NR may be connected to one or more TRPs within one or more gNBs.

[0048] It should be noted that the UE 106 is capable of communicating using multiple wireless communication standards. For example, in addition to at least one cellular communication protocol (e.g., GSM, UMTS (associated with, for example, WCDMA or TD-SCDMA air interface), LTE, LTE-A, 5G NR, HSPA, 3GPP2CDMA2000 (e.g., 1xRTT, 1xEV-DO, HRPD, eHRPD), etc.), the UE 106 can be configured to communicate using wireless networking (e.g., Wi-Fi) and / or peer-to-peer wireless communication protocols (e.g., Bluetooth, Wi-Fi peer-to-peer, etc.). If desired, the UE 106 can also or alternatively be configured to communicate using one or more global navigation satellite systems (GNSS, such as GPS or GLONASS), one or more mobile television broadcast standards (e.g., ATSC-M / H or DVB-H), and / or any other wireless communication protocols. Other combinations of wireless communication standards (including more than two wireless communication standards) are also possible.

[0049] Figure 2 A UE 106A is shown that can communicate via uplink and downlink communications with the base station 102 according to some embodiments. The UEs may each be a device with cellular communication capabilities, such as a mobile phone, handheld device, computer or tablet computer, or virtually any type of wireless device.

[0050] The UE may include a processor configured to execute program instructions stored in a memory. The UE may perform any of the method implementations described herein by executing such stored instructions. Alternatively or in addition, the UE may include a programmable hardware element such as an FPGA (field programmable gate array) configured to perform any of the method implementations described herein, or any part of any of the method implementations described herein.

[0051] The UE may include one or more antennas for communicating using one or more wireless communication protocols or technologies. In some aspects, the UE may be configured to communicate using, for example, CDMA2000 (1xRTT / 1xEV-DO / HRPD / eHRPD) or LTE using a single shared radio and / or GSM or LTE using a single shared radio. The shared radio may be coupled to a single antenna, or may be coupled to multiple antennas (e.g., for MIMO) for performing wireless communications. Typically, the radio component may include any combination of a baseband processor, an analog radio frequency (RF) signal processing circuit (e.g., including filters, mixers, oscillators, amplifiers, etc.), or a digital processing circuit (e.g., for digital modulation and other digital processing). Similarly, the radio component may use the aforementioned hardware to implement one or more receive chains and transmit chains. For example, the UE 106 may share one or more portions of a receive chain and / or transmit chain between a variety of wireless communication technologies such as those discussed above.

[0052] In some embodiments, the UE may include a separate transmit chain and / or receive chain (e.g., including separate antennas and other radio components) for each wireless communication protocol with which it is configured to communicate. As another possibility, the UE may include one or more radio components shared between multiple wireless communication protocols, and one or more radio components used uniquely by a single wireless communication protocol. For example, the UE may include a shared radio component for communicating using either LTE or 5G NR (or LTE or 1xRTT, or LTE or GSM), and a separate radio component for communicating using each of Wi-Fi and Bluetooth. Other configurations are also possible.

[0053] In some embodiments, the UE and the base station can communicate via NR (also known as NR-U) in an unlicensed band. NR-U is an operating mode included in NR Release 16, which defines a technology for cellular operators to integrate unlicensed spectrum (e.g., frequencies greater than or equal to 52 GHz or between 52.6 GHz and 71 GHz) into 5G networks. The radio waves in this band have wavelengths in the so-called millimeter band, and the radiation in this band is called millimeter waves. NR-U implements both uplink and downlink operations in unlicensed bands. NR-U supports new features, such as wideband carriers, flexible parameter sets, dynamic TDD, beamforming, and dynamic scheduling / HARQ timing. However, there are issues with dynamic scheduling, as discussed in other sections.

[0054] Figure 3 An exemplary simplified block diagram of a communication device 106 according to some embodiments is shown. Note that Figure 3The block diagram of the communication device is only an example of a possible communication device. According to the embodiment, in addition to other devices, the communication device 106 can be a UE device, a mobile device or a mobile station, a wireless device or a wireless station, a desktop computer or a computing device, a mobile computing device (e.g., a laptop computer, a notebook or a portable computing device), a tablet computer and / or a combination of devices. As shown in the figure, the communication device 106 may include a group of components 300 configured to perform core functions. For example, the group of components may be implemented as a system on a chip (SOC), which may include parts for various purposes. Alternatively, the group of components 300 may be implemented as a separate component or a group of components for various purposes. This group of components 300 may be (e.g., communicatively; directly or indirectly) coupled to various other circuits of the communication device 106.

[0055] For example, the communication device 106 may include various types of memory (e.g., including NAND flash memory 310), input / output interfaces such as a connector I / F 320 (e.g., for connecting to a computer system; a docking station; a charging station; an input device such as a microphone, a camera, a keyboard; an output device such as a speaker; etc.), a display 360 that may be integrated with the communication device 106 or external to the communication device 106, and cellular communication circuits 330 such as for 5G NR, LTE, GSM, etc., and short-range to medium-range wireless communication circuits 329 (e.g., Bluetooth TM In some embodiments, the communication device 106 may include wired communication circuitry (not shown), such as, for example, a network interface card for Ethernet.

[0056] Cellular communication circuitry 330 may be (e.g., communicatively; directly or indirectly) coupled to one or more antennas, such as antennas 335 and 336 as shown. Short-range to medium-range wireless communication circuitry 329 may also be (e.g., communicatively; directly or indirectly) coupled to one or more antennas, such as antennas 337 and 338 as shown. Alternatively, short-range to medium-range wireless communication circuitry 329 may be (e.g., communicatively; directly or indirectly) coupled to antennas 335 and 336 in addition to or in lieu of being (e.g., communicatively; directly or indirectly) coupled to antennas 337 and 338. Short-range to medium-range wireless communication circuitry 329 and / or cellular communication circuitry 330 may include multiple receive chains and / or multiple transmit chains for receiving and / or transmitting multiple spatial streams, such as in a multiple-input-multiple-output (MIMO) configuration.

[0057] In some embodiments, as further described below, the cellular communication circuit 330 may include dedicated receive chains (including and / or coupled to (e.g., communicatively; directly or indirectly) dedicated processors and / or radio components) for multiple RATs (e.g., a first receive chain for LTE and a second receive chain for 5G-NR). In addition, in some embodiments, the cellular communication circuit 330 may include a single transmit chain that can switch between radio components dedicated to specific RATs. For example, a first radio component may be dedicated to a first RAT, such as LTE, and may communicate with a dedicated receive chain and a transmit chain shared with an additional radio component, such as a second radio component that may be dedicated to a second RAT (e.g., 5G NR) and may communicate with the dedicated receive chain and the shared transmit chain.

[0058] The communication device 106 may also include and / or be configured for use with one or more user interface elements. The user interface elements may include various elements such as a display 360 (which may be a touch screen display), a keyboard (which may be a separate keyboard or may be implemented as part of a touch screen display), a mouse, a microphone and / or speakers, one or more cameras, one or more buttons, and / or any of a variety of other elements capable of providing information to a user and / or receiving or interpreting user input.

[0059] The communication device 106 may also include one or more smart cards 345 having SIM (Subscriber Identity Module) functionality, such as one or more UICC cards (one or more Universal Integrated Circuit Cards) 345 .

[0060] As shown, the SOC 300 may include a processor 302 that may execute program instructions for the communication device 106 and a display circuit 304 that may perform graphics processing and provide display signals to a display 360. The processor 302 may also be coupled to a memory management unit (MMU) 340 (which may be configured to receive addresses from the processor 302 and convert those addresses to locations in a memory (e.g., memory 306, read-only memory (ROM) 350, NAND flash memory 310)) and / or to other circuits or devices (such as display circuit 304, short-range wireless communication circuit 229, cellular communication circuit 330, connector I / F 320, and / or display 360). The MMU 340 may be configured to perform memory protection and page table translation or setup. In some embodiments, the MMU 340 may be included as part of the processor 302.

[0061] As described above, the communication device 106 may be configured to communicate using wireless and / or wired communication circuitry.The communication device 106 may also be configured to provide PDCCH monitoring and associated configuration of such monitoring for user equipment devices and base stations.

[0062] As described herein, the communication device 106 may include hardware and software components for implementing the above features for performing PDCCH monitoring for the communication device 106 and the base station. For example, by executing program instructions stored on a memory medium (e.g., a non-transitory computer-readable memory medium), the processor 302 of the communication device 106 may be configured to implement part or all of the features described in the present invention. Alternatively (or in addition), the processor 302 may be configured as a programmable hardware element, such as an FPGA (field programmable gate array) or an ASIC (application-specific integrated circuit). Alternatively (or in addition), in combination with one or more of the other components 300, 304, 306, 310, 320, 329, 330, 340, 345, 350, 360, the processor 302 of the communication device 106 may be configured to implement part or all of the features described herein.

[0063] In addition, as described in the present invention, processor 302 may include one or more processing elements. Therefore, processor 302 may include one or more integrated circuits (ICs) configured to perform the functions of processor 302. In addition, each integrated circuit may include circuits (e.g., first circuits, second circuits, etc.) configured to perform the functions of one or more processors 302.

[0064] In addition, as described herein, both the cellular communication circuit 330 and the short-range wireless communication circuit 329 may include one or more processing elements. In other words, one or more processing elements may be included in the cellular communication circuit 330, and similarly, one or more processing elements may be included in the short-range wireless communication circuit 329. Therefore, the cellular communication circuit 330 may include one or more integrated circuits (ICs) configured to perform the functions of the cellular communication circuit 330. In addition, each integrated circuit may include a circuit (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of the cellular communication circuit 230. Similarly, the short-range wireless communication circuit 329 may include one or more ICs configured to perform the functions of the short-range wireless communication circuit 32. In addition, each integrated circuit may include a circuit (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of the short-range wireless communication circuit 329.

[0065] Figure 4 An exemplary block diagram of a base station 102 according to some embodiments is shown. Note that Figure 4The base station of is only one example of a possible base station. As shown, the base station 102 may include a processor 404 that may execute program instructions for the base station 102. The processor 404 may also be coupled to a memory management unit (MMU) 440 or other circuit or device, which may be configured to receive addresses from the processor 404 and convert these addresses to locations in memory (e.g., memory 460 and read-only memory (ROM) 450).

[0067] The network port 470 (or an additional network port) may also or alternatively be configured to couple to a cellular network, such as a core network of a cellular service provider. The core network may provide mobility-related services and / or other services to multiple devices, such as the UE device 106. In some cases, the network port 470 may be coupled to a telephone network via the core network, and / or the core network may provide a telephone network (e.g., in other UE devices served by the cellular service provider).

[0068] In some embodiments, base station 102 may be a next generation base station, such as a 5G New Radio (5G NR) base station, or "gNB". In such embodiments, base station 102 may be connected to a legacy evolved packet core (EPC) network and / or to an NR core (NRC) network. In addition, base station 102 may be considered a 5G NR cell and may include one or more transition and reception points (TRPs). In addition, a UE capable of operating in accordance with 5G NR may be connected to one or more TRPs within one or more gNBs. In some embodiments, the base station may operate in a 5G NR-U mode or in a mode operating in a spectrum above the 52.6 GHz band.

[0069] The base station 102 may include at least one antenna 434 and possibly multiple antennas. The at least one antenna 434 may be configured to function as a wireless transceiver and may be further configured to communicate with the UE device 106 via the radio component 430. The antenna 434 communicates with the radio component 430 via a communication chain 432. The communication chain 432 may be a receive chain, a transmit chain, or both. The radio component 430 may be configured to communicate via various wireless communication standards, including but not limited to 5G NR, 5G NR-U, LTE, LTE-A, GSM, UMTS, CDMA2000, Wi-Fi, etc.

[0070] Base station 102 may be configured to perform wireless communications using multiple wireless communication standards. In some cases, base station 102 may include multiple radios that enable base station 102 to communicate according to multiple wireless communication technologies. For example, as one possibility, base station 102 may include an LTE radio component for performing communications according to LTE and a 5G NR radio component for performing communications according to 5G NR and 5G NR-U. In this case, base station 102 may be able to operate as both an LTE base station and a 5GNR base station. As another possibility, base station 102 may include a multimode radio component capable of performing communications according to any one of a plurality of wireless communication technologies (e.g., 5GNR and Wi-Fi, LTE and Wi-Fi, LTE and UMTS, LTE and CDMA2000, UMTS and GSM, etc.).

[0072] In addition, as described herein, processor 404 may be composed of one or more processing elements. In other words, one or more processing elements may be included in processor 404. Therefore, processor 404 may include one or more integrated circuits (ICs) configured to perform the functions of processor 404. In addition, each integrated circuit may include circuits (e.g., first circuits, second circuits, etc.) configured to perform the functions of one or more processors 404.

[0073] Additionally, as described herein, radio 430 may be comprised of one or more processing elements. In other words, one or more processing elements may be included in radio 430. Thus, radio 430 may include one or more integrated circuits (ICs) configured to perform the functions of radio 430. Furthermore, each integrated circuit may include circuits (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of radio 430.

[0074] Figure 5 An exemplary simplified block diagram of a cellular communication circuit according to some embodiments is shown. Note that Figure 5 The block diagram of the cellular communication circuitry of is only one example of possible cellular communication circuitry. According to an embodiment, the cellular communication circuitry 330 may be included in a communication device such as the communication device 106 described above. As described above, the communication device 106 may be a user equipment (UE) device, a mobile device or mobile station, a wireless device or wireless station, a desktop computer or computing device, a mobile computing device (e.g., a laptop, notebook, or portable computing device), a tablet computer, and / or a combination of devices, among other devices.

[0075] Cellular communication circuitry 330 may be (eg, communicatively; directly or indirectly) coupled to one or more antennas, such as ( Figure 3 335a to 335b and antenna 336 as shown in FIG. 335b and antenna 336 as shown in FIG. 335b. In some embodiments, cellular communication circuit 330 may include dedicated receive chains (including and / or coupled to (e.g., communicatively; directly or indirectly) dedicated processors and / or radio components) for multiple RATs (e.g., a first receive chain for LTE and a second receive chain for 5G-NR). For example, Figure 5 As shown, the cellular communication circuit 330 may include a modem 510 and a modem 520. The modem 510 may be configured for communication according to a first RAT (e.g., such as LTE or LTE-A), and the modem 520 may be configured for communication according to a second RAT (e.g., such as 5G NR).

[0076] As shown, the modem 510 may include one or more processors 512 and a memory 516 in communication with the processor 512. The modem 510 may communicate with a radio frequency (RF) front end 530. The RF front end 530 may include circuits for transmitting and receiving radio signals. For example, the RF front end 530 may include a receiving circuit (RX) 532 and a transmitting circuit (TX) 534. In some embodiments, the receiving circuit 532 may communicate with a downlink (DL) front end 550, which may include circuits for receiving radio signals via an antenna 335a.

[0077] Similarly, the modem 520 may include one or more processors 522 and a memory 526 in communication with the processor 522. The modem 520 may communicate with the RF front end 540. The RF front end 540 may include circuits for transmitting and receiving radio signals. For example, the RF front end 540 may include a receiving circuit 542 and a transmitting circuit 544. In some embodiments, the receiving circuit 542 may communicate with the DL front end 560, which may include circuits for receiving radio signals via the antenna 335b.

[0078] In some embodiments, the switch 570 may couple the transmit circuit 534 to an uplink (UL) front end 572. In addition, the switch 570 may couple the transmit circuit 544 to the UL front end 572. The UL front end 572 may include circuitry for transmitting radio signals via the antenna 336. Thus, when the cellular communication circuit 330 receives an instruction to transmit according to a first RAT (e.g., via a transmit chain including the transmit circuit 534 and the UL front end 572) supported by the modem 510, the switch 570 may be switched to a first state that allows the modem 510 to transmit signals according to the first RAT (e.g., via a transmit chain including the transmit circuit 534 and the UL front end 572). Similarly, when the cellular communication circuit 330 receives an instruction to transmit according to a second RAT (e.g., via a transmit chain including the transmit circuit 544 and the UL front end 572) supported by the modem 520, the switch 570 may be switched to a second state that allows the modem 520 to transmit signals according to the second RAT (e.g., via a transmit chain including the transmit circuit 544 and the UL front end 572).

[0079] As described herein, the modem 510 may include hardware and software components for implementing the above features or for determining a physical downlink shared channel for a user equipment device and a base station and for various other technologies described herein. For example, by executing program instructions stored on a memory medium (e.g., a non-transitory computer-readable memory medium), the processor 512 may be configured to implement part or all of the features described herein. Alternatively (or in addition thereto), the processor 512 may be configured as a programmable hardware element such as an FPGA (field programmable gate array), or as an ASIC (application-specific integrated circuit). Alternatively (or in addition thereto), in combination with one or more of the other components 530, 532, 534, 550, 570, 572, 335, and 336, the processor 512 may be configured to implement part or all of the features described herein.

[0080] In addition, as described herein, processor 512 may include one or more processing elements. Thus, processor 512 may include one or more integrated circuits (ICs) configured to perform the functions of processor 512. In addition, each integrated circuit may include circuits (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of processor 512.

[0081] As described herein, the modem 520 may include hardware and software components for implementing the above-mentioned features for determining physical downlink shared channel scheduling resources for user equipment devices and base stations and for various other technologies described herein. For example, by executing program instructions stored on a memory medium (e.g., a non-transitory computer-readable memory medium), the processor 522 may be configured to implement part or all of the features described herein. Alternatively (or in addition thereto), the processor 522 may be configured as a programmable hardware element such as an FPGA (field programmable gate array), or as an ASIC (application-specific integrated circuit). Alternatively (or in addition thereto), in combination with one or more of the other components 540, 542, 544, 550, 570, 572, 335, and 336, the processor 522 may be configured to implement part or all of the features described herein.

[0082] In addition, as described herein, processor 522 may include one or more processing elements. Thus, processor 522 may include one or more integrated circuits (ICs) configured to perform the functions of processor 522. In addition, each integrated circuit may include circuits (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of processor 522.

[0083] In one embodiment, PDCCH monitoring is performed by the UE to obtain downlink control information (DCI) to provide the UE with information about uplink and / or downlink transmissions. This information includes, for example, but is not limited to, physical layer resource allocations, power control commands, HARQ information for both uplink and downlink, and other information for facilitating uplink and downlink transmissions. In one embodiment, PDCCH monitoring is symbol-level monitoring.

[0084] Figure 6 is a data flow diagram of one embodiment of a configuration process for configuring a wireless device. Figure 6 , the gNB (or other network node) 601 includes a determination module 601A for determining a PDCCH search space monitoring configuration for a UE (or other wireless device) (such as UE 602), and generating configuration information to configure the UE to perform PDCCH search space monitoring according to the PDCCH search space monitoring configuration. The transmission module 601B transmits monitoring configuration information 603 (e.g., configuration information for configuring the wireless device to perform PDCCH search space monitoring).

[0085] The UE 602 includes a receiving module 602A for receiving monitoring configuration information 603 and a UE configuration module 602B for configuring the UE 602 based on the monitoring configuration information 603. In this case, the UE configuration module 602B performs necessary decoding and processing of the monitoring configuration information 603 to obtain information for configuring the UE 602, including information enabling the UE to perform functions related to PDCCH monitoring.

[0086] The UE may be configured to perform PDCCH monitoring on the first 3 OFDM symbols of a time slot. This is referred to herein as configuration 1-1. In another embodiment, the UE may be configured to perform PDCCH monitoring on 3 consecutive OFDM symbols of a time slot. This is referred to herein as configuration 1-2. In this configuration, the UE capability signaling indicates whether the UE supports receiving PDCCH scrambled with C-RNTI or CS-RNTI in a search space that is configured to monitor within a single span of any three consecutive OFDM symbols in a time slot, and the configuration is only used for one frequency range (e.g., frequency range 1 (FR1) of 5G NR).

[0087] In yet another UE configuration, referred to as usage configuration 2, the UE may be configured to perform PDCCH monitoring that monitors the opportunities of the Class 1 Common Search Space (CSS), Class 3 CSS, and UE Search Space (UE-SS) on any OFDM symbol of a slot with a dedicated Radio Resource Control (RRC) configuration. In one usage, this is an optional feature of the UE capability signaling indicating one of two options: 1) In the case where there is no gap between two DCIs, or the i-th minimum time interval between two unicast DCIs: 2 symbols / 15kHz, 4 symbols / 30kHz, 7 symbols / 60kHz NCP, and 12 symbols / 120kHz.

[0088] In yet another configuration, the UE performs PDCCH monitoring for a monitoring opportunity, and the monitoring may be any OFDM symbol for a slot of configuration 2 with a span gap. Figure 7An example of a span gap is shown, where X represents the distance between spans in terms of symbols, and Y represents the length of the span in terms of symbols. In the configuration previously defined in NR, the PDCCH monitoring configuration information indicates whether the UE supports PDCCH search space monitoring opportunities in any symbol of the time slot, where there is a minimum time interval between two consecutive transmissions of the PDCCH, and a span of up to two OFDM symbols for two OFDM symbols or a span of up to three OFDM symbols for four and seven OFDM symbols. In one configuration, the supported value set (X, Y) is (7, 3). In another configuration, the supported value set (X, Y) includes (4, 3) and (7, 3). In yet another configuration, the supported value set (X, Y) is (2, 2), (4, 3), and (7, 3).

[0089] In one configuration, for a set of monitoring opportunities within the same span, there is 1 downlink (DL) DCI + 1 uplink (UL) DCI for each scheduled CC across the set of monitoring opportunities for FDD, and there is 1 DL DCI + up to 2 UL DCIs for each scheduled CC across the set of monitoring opportunities for TDD. The number of different starting symbol indices for the span of all PDCCH monitoring opportunities for each time slot (including PDCCH monitoring opportunities configured 1-1) is not greater than floor(14 / X), where X is an integer representing the minimum value among the values ​​reported by the UE. In one configuration, in a secondary cell (SCell), the number of different starting symbol indices for PDCCH monitoring opportunities for each time slot (including PDCCH monitoring opportunities configured 1-1) does not exceed 7, and the number of different starting symbol indices for PDCCH monitoring opportunities for each half time slot (including PDCCH monitoring opportunities configured 1-1) does not exceed 4.

[0090] As discussed above, the UE is configured with a scheduling complexity that enables the UE to perform a predetermined number of blind decoding candidates (e.g., a maximum number of monitored PDCCH candidates) and a predetermined number of non-overlapping CCEs (and their associated channel estimates) per slot per CC. In one configuration defined in NR Release 15, the UE has a scheduling complexity unit equal to 1 slot (i.e., the monitoring limit is per slot per component carrier (CC)), where the scheduling complexity unit is defined as the duration within which the complexity limit is valid. Fig. 8A and Figure 8BThe maximum number of monitored PDCCH candidates per CC per time slot and the maximum number of non-overlapping CCEs (and their associated channel estimates) per CC per time slot are shown. In the event that the monitoring limit is exceeded, the UE has experienced an overage and the UE may use a discarding algorithm to perform discarding per time slot so that the UE stops performing any additional blind decoding for that time slot and processing any additional non-overlapping CCEs for that time slot.

[0091] In the configuration defined in NR Release 16, the scheduling complexity unit is equal to 1 span (i.e., the monitoring limit is per CC per span). In this case, the monitoring limit includes a per-CC limit on the maximum number of non-overlapping CCEs per monitoring span for all span configurations and the maximum number of monitored PDCCH candidates per monitoring span. Fig. 9A and Fig. 9B The maximum number of monitored PDCCH candidates per CC per time slot (number of blind decodes) and the maximum number of non-overlapping CCEs (and their associated channel estimates) per CC per time slot are shown. In this configuration, the span is defined as (2,2), (4,3), or (7,3) according to (X,Y), as for the configurations discussed above. These limits are approximately twice the span-based monitoring limits for the configurations defined in NR Release 15. For example, if the time slots are normalized, the span configuration (7,3) has 2 spans in the time slot and the limit is 2*56 (or twice the configuration defined in NR Release 15). In the event that the complexity limit is exceeded and the UE has experienced an overage, the UE may use a discarding algorithm to perform discarding of each span so that the UE stops performing any additional blind decoding for that span and processing any additional non-overlapping CCEs for that span.

[0092] In the above 52.6 GHz transmission, the subcarrier spacing (SCS) is increased to provide robustness to phase noise. In one embodiment, the SCS supported by the UE and gNB (or other network nodes) for transmission in the communication system is a set of SCSs including 120kHz, 240kHz, 480kHz, and 960kHz, as well as 1920kHz. However, the set of SCSs may include less than all of these SCSs and may include other SCSs. This increase in subcarrier spacing results in a reduction in the size of symbols (e.g., OFDM symbols). For example, comparing a 120kHz SCS with a 960kHz SCS, the size of the symbol is reduced by a factor of 8.

[0093] The reduction in symbol size leads to at least one problem. If the PDCCH monitoring process is not changed from that used in 5GNR, the UE may be required to increase its PDCCH processing capabilities. In the previous example, when comparing 120kHz to 960kHz, the UE will have to perform up to eight times more PDCCH processing.

[0094] Furthermore, due to the smaller symbol size, the complexity of performing PDCCH monitoring by the UE is more difficult. This is especially true if the PDCCH monitoring results in multiple PDCCH monitoring periodicities less than 14 symbols. This will prevent the use of feature groups (FG) 3-5, FG 3-5a and FG 3-5b described above.

[0095] In one embodiment, a UE is configured to perform PDCCH monitoring for SCSs in a group of different subcarrier spacings (SCSs) associated with spectrum above 52.6 GHz in 5G New Radio (NR) (including, for example, 120 kHz, 240 kHz, 480 kHz, and 960 kHz in one embodiment), wherein PDCCH search space monitoring includes PDCCH monitoring for one of these subcarrier spacings (SCSs), and detection restrictions associated with each of these SCSs (including the number of blind decodings (BDs) and the number of CCEs per component carrier (CC)) are applied per time slot per CC, and the UE decoding complexity associated with performing the monitoring restrictions for different SCSs in the group is equal. That is, the UE decoding complexity associated with performing the monitoring restrictions for different SCSs in the group is equal because even if the number of blind decodings (BDs) and the number of CCEs per component carrier (CC) change with changes in the SCS and its associated duration, the overall UE complexity relative to applying the monitoring restrictions does not increase compared to the configuration previously defined in NR. In other words, it remains constant over the same duration. In one embodiment, the overall UE complexity with respect to the application of monitoring restrictions is the same as or greater than NR.

[0096] In one embodiment, the UE decoding complexity associated with performing monitoring restrictions for different SCSs in the set is maintained by having the PDCCH monitoring performed by the UE for an SCS in the set of SCSs be scaled based on the SCS. Fig. 8A and Figure 8BThe maximum number of monitored candidates per CC per time slot (e.g., candidates requiring blind decoding (BD)) and the maximum number of non-overlapping CCEs per CC per time slot (e.g., the number of CCEs requiring channel estimation) are scaled for SCSs of 120kHz, 240kHz, 480kHz, and 960kHz compared to those SCSs with subcarrier spacing configurations μ of 0 to 2.

[0097] In one embodiment, the scaling is uniform across all SCSs. For example, in a configuration referred to herein as Configuration 1-1, in which PDCCH monitoring is limited to the first three OFDM symbols in a timeslot, or in another configuration referred to herein as Configuration 1-2, in which PDCCH monitoring may occur in any span of up to three consecutive OFDM symbols, the monitoring limits relative to the maximum number of candidates for monitoring per CC per timeslot and the maximum number of non-overlapping CCEs per CC per timeslot for SCSs of 120 kHz, 240 kHz, 480 kHz, and 960 kHz are all scaled identically. In one embodiment, the monitoring limits relative to the maximum number of candidates for monitoring per CC per timeslot and the maximum number of non-overlapping CCEs per CC per timeslot for SCSs of 120 kHz, 240 kHz, 480 kHz, and 960 kHz are both 20 and 32, respectively. This example is shown in the table Fig. 10A and Fig. 10B Therefore, from the scheduling complexity point of view, the scheduling complexity unit keeps the BD and CCE limit per time slot per CC the same for all . Note that this requires a significant increase in UE complexity.

[0098] In another embodiment, using Configuration 1-1 or Configuration 1-2 with a new SCS, the scaling changes with the change in SCS. In one embodiment, the scaled BD (blind decoding) and CCE limits are based on the increase in complexity (e.g., 2x) and the change in SCS. In one embodiment, the monitoring limit ratio Fig. 10A and Fig. 10B The limits shown in the scaling limits for option 1 in the are scaled by a factor of two and Fig. 10A and Fig. 10B As shown in Option 2. Again, as with Option 1, the BD and CCE monitoring limit is per CC per timeslot.

[0099] Fig.11 An example of scaling PDCCH monitoring based on SCS is shown. Fig.11 , OFDM symbol 1101 represents one time slot at 120 kHz, and OFDM symbol 1102 represents the PDCCH information in the first three symbols of each of the eight time slots at 960 kHz. Fig.11as well as Figure 12 to Figure 14 , Fig.16 and Fig.17 , for the 960kHz case, each color change is a different time slot, while for the 120kHz case, each color change is a single symbol. Therefore, the yellow time slot in the 960kHz case maps to a symbol in the 120kHz case.

[0100] In another embodiment where the UE is configured to perform PDCCH monitoring according to option 1 or 2, the UE performs PDCCH monitoring only for up to X symbols (or within a span thereof), where X is an integer less than or equal to 3 (e.g., 1, 2, 3). Therefore, the monitoring opportunity (MO) may be up to three OFDM symbols, thereby reducing the maximum number of symbols allowed to be monitored.

[0101] In another embodiment, the UE is configured to perform PDCCH monitoring, wherein the PDCCH monitoring limit is defined within a group of time slots (i.e., a time slot group). In other words, the scheduling complexity unit extends within the time slot group rather than within a time slot or span as described above, so that the duration to which they are applied exceeds the duration of all time slots in the group. This may be referred to herein as time slot scheduling complexity aggregation. Therefore, the UE stops performing blind decoding of each time slot per CC and / or processing non-overlapping CCEs per time slot per CC until the limit has been exceeded during the duration of the time slot group.

[0102] In some embodiments, the slot group does not set restrictions on when the action of the DCI occurs. For example, the slot group does not control when the PDSCH is scheduled. In addition, in some embodiments, the DCI decoded within the slot group can schedule an action (or multiple actions) outside the slot group. For example, the DCI decoded within the slot group can schedule a single PDSCH or multiple PDSCHs based on cross-slot group scheduling. In addition, setting monitoring restrictions to extend over the duration of a group of slots allows the complexity of the PDCCH to be defined over multiple slots, while allowing single or multiple PUSCH / PDSCH instances to be scheduled within a slot group (same slot group scheduling) or across slot groups (cross slot / cross slot group scheduling).

[0103] In another embodiment, the UE is configured to perform PDCCH monitoring with restrictions defined within a timeslot group to limit the increase in complexity of the UE seen in the uniformly scaled PDCCH monitoring configuration described above (where BD and non-overlapping CCE restrictions are uniformly scaled for SCS of 120kHz, 240kHz, 480kHz, 960kHz) and the complexity restrictions per timeslot seen in the SCS-based scaling implementation (where BD and CCE restrictions are scaled based on SCS), where the complexity restrictions are distributed over multiple timeslots. This may be advantageous in situations in beam-based systems where some timeslots may not have any beams. In some embodiments, when compared to other configurations previously defined in NR described above, the complexity restrictions for the timeslot can be "used" by another timeslot within the timeslot group without increasing the overall complexity load.

[0104] In one embodiment, these timeslot group complexity limits are defined based on a reference SCS. For example, in one embodiment, the monitoring limits applied by the UE are set equal to the limits of the reference SCS. For example, assume that the transmitted SCS is equal to 960kHz and the reference SCS = 120kHz. In this case, the scheduling complexity unit of the transmitted SCS is 8 timeslots (i.e., the timeslot group size is equal to 8), and the BD / CCE limits for each timeslot group per CC are defined and set to values ​​based on the limits for the reference SCS, which are BD / CCE limits associated with an SCE of 120kHz. Therefore, when the transmitted SCS is 960kHz, the blind decoding (BD) limit for 120kHz is equal to 20 and applied to the UE. Therefore, in one embodiment, the BD limit is set to a value (20N, N = 1, 2, 3, etc.) and the CCE limit is set to a value (32N, N = 1, 2, 3, etc.) (e.g., (if N = 1, BD: 20, CCE: 32; if N = 2, BD: 40, CCE: 64)).

[0105] In one embodiment, the UE is configured with configuration information for specifying the PDCCH monitoring occasion (MO) of the time slot group. In some embodiments, the information specifies the position of the PDCCH MO. For example, in one embodiment, the information specifies the position of the PDCCH MO for each time slot in the time slot group. In another embodiment, the information specifies the position of the PDCCH MO defined within the time slot group, rather than each time slot in the time slot group. In this case, in one embodiment, for each time slot in the time slot group, PDCCH monitoring occurs within the first X symbols, where X is an integer. Fig.12 An example of this approach is shown in Fig.12, for an SCS of 120 kHz, a certain number of time slots are shown in OFDM symbol 1201, and for an SCS of 960 kHz, the information in OFDM symbol 1201 is aggregated into 8 time slots in 1202, where the PDCCH information is located in the first two symbols of each time slot. In one embodiment, X is configured (e.g., by the gNB). In another embodiment, X is SCS-dependent. In one embodiment, for an SCS of 240 kHz, X is 3, for an SCS of 480 kHz, X is 6, and for an SCS of 960 kHz, X is 12. In another embodiment, for each time slot in a time slot group, PDCCH monitoring occurs on any span of X consecutive symbols within that time slot, where X is an integer. Fig.12 Such an example is shown in OFDM symbol 1203 in FIG, where for an SCS of 960 kHz, the information in OFDM symbol 1201 is aggregated into 8 slots, where the PDCCH information is located in two symbols in each of these slots, but at different locations in two or more slots. In one embodiment, X is configured (e.g., by the gNB). In another embodiment, X is SCS-dependent. In one embodiment, for an SCS of 240 kHz, X is 3, for an SCS of 480 kHz, X is 6, and for an SCS of 960 kHz, X is 12.

[0106] In some embodiments where the information specifies the location of the PDCCH MO, a PDCCH monitoring opportunity is defined for each slot group. In this case, in one embodiment, for each slot in the slot group, PDCCH monitoring occurs within the first X symbols, where X is an integer. Fig.12 An example of this is shown in OFDM symbol 1204, where for an SCS of 960 kHz, the information in OFDM symbol 1201 is aggregated into 8 slots and the PDCCH information is located at the beginning of the first slot. In one embodiment, X is configured (e.g., by the gNB). In another embodiment, X is SCS-dependent. In one embodiment, for an SCS of 240 kHz, X is 3, for an SCS of 480 kHz, X is 6, and for an SCS of 960 kHz, X is 12. In another embodiment, for each slot in a slot group, PDCCH monitoring occurs on any span of X consecutive symbols within that slot, where X is an integer. Fig.12An example of this is shown in OFDM symbol 1205 in FIG, where for an SCS of 960 kHz, the information in OFDM symbol 1201 is aggregated into 8 slots and the PDCCH information appears in the third slot. In one embodiment, X is configured (e.g., by the gNB). In another embodiment, X is SCS dependent. In one embodiment, for an SCS of 240 kHz, X is 3, for an SCS of 480 kHz, X is 6, and for an SCS of 960 kHz, X is 12.

[0107] In one embodiment, PDCCH monitoring can be causal or non-causal. When causal, PDCCH MO is only applied to symbols at the same time or in the future. When non-causal, PDCCH MO can be applied to any symbol starting from the beginning of the PDCCH time slot group.

[0108] In one embodiment, when a UE has a monitoring limit distributed over a group of time slots and it reaches its limit and an overage occurs, the UE applies one or more algorithms to perform a discard. In one embodiment, the overage and discard are performed for each group of time slots. In another embodiment, the overage and discard are performed for each time slot within a group of time slots. In this case, each time slot within a group of time slots may be overage and discarded based on the limit of each time slot.

[0109] Optionally, in one embodiment, the UE is configured such that there is a minimum spacing between PDCCH MOs within a slot group. In one embodiment, the minimum spacing is at least one in each slot. Note that other minimum spacings may be used.

[0110] Optionally, in one embodiment, the UE is configured to perform PDCCH monitoring based on a uniform distribution of PDCCH MOs in the time slots of the time slot group. Optionally, in another embodiment, the UE is configured to perform PDCCH monitoring based on a non-uniform distribution of PDCCH MOs in the time slots of the time slot group.

[0111] In one embodiment, the slot groups are configurable. In one embodiment, the configuration of the slot groups is semi-static. In one embodiment, this is controlled by the gNB or another network node. In one embodiment, where the slot groups have a semi-static slot group configuration, the number of slots in the slot groups, the MO distribution within each slot group, and / or the restrictions on each slot group are communicated to the UE in a semi-static manner. For example, in one embodiment, such information may be communicated via an RRC configuration.

[0112] In one embodiment, in case of a semi-static timeslot group configuration, the number of timeslots scheduled for each monitoring opportunity is semi-static.In one embodiment, scheduling for a plurality of aggregated timeslots is performed by a scheduling unit. Fig.13 is an example of a static aggregate. Fig.13 , OFDM symbol 1301 shows one slot at 120 kHz where PDCCH information appears in the first 24 symbols of the slot, OFDM symbol 1302 shows 8 slots at 960 kHz where information is aggregated over two slots, and OFDM symbol 1303 shows 8 slots at 960 kHz where information is aggregated over seven slots. OFDM symbol 1301 represents a reference. OFDM symbol 1302 shows the result of performing semi-static aggregation relative to OFDM symbol 1301, resulting in 3 symbols per slot group at the beginning of the slot group (X equals 3), where the slot group size is 2 slots. OFDM symbol 1303 shows the result of performing semi-static aggregation relative to OFDM symbol 1301, resulting in 9 symbols per slot group at the beginning of the slot group (X equals 9), where the slot group size is 8 slots.

[0113] In one embodiment, when the time slot groups have a semi-static time slot group configuration, these time slot groups are non-overlapping and adjacent to each other. In another embodiment, when the time slot groups have a semi-static time slot group configuration, these time slot groups are non-overlapping and may not be adjacent to each other. This may allow power saving when no valid time slot groups are defined. In another embodiment where the time slot groups have a semi-static time slot group configuration, these time slot groups may be overlapping.

[0114] In one embodiment, semi-static configuration allows different slot group sizes to be configured simultaneously. For example, at time t1, the slot group size is 8, while at time t2, the slot group size is 16. In one embodiment, the slot group configuration is tied to the subcarrier spacing (SCS).

[0115] In one embodiment, the configuration of the time slot groups is dynamic. In one embodiment, this is controlled by the gNB or another network node. In one embodiment, where the time slot groups have a dynamic time slot group configuration, the number of time slots in the time slot groups, the MO distribution within each time slot group, and / or the restrictions on each time slot group are dynamically transmitted to the UE. In one embodiment, this information is transmitted via L-1 signaling. However, in an alternative embodiment, this information may be communicated using another type of signaling or an alternative communication mechanism. In one embodiment, the UE is configured with multiple time slot group configurations, and L-1 signaling is used to dynamically switch between time slot group configurations, allowing the time slot group size to change dynamically over time.

[0116] In one embodiment, in case of dynamic slot group configuration, the number of time slots scheduled for each monitoring opportunity is dynamic.In one embodiment, scheduling for a plurality of aggregated time slots is performed by a scheduling unit. Fig.14 is an example of a dynamic aggregation. Fig.14 , OFDM symbol 1401 shows a slot at 120kHz, where PDCCH information appears in the first 24 symbols of the slot and represents a reference. OFDM symbol 1402 shows aggregated slots at 960kHz, where 4 slots are aggregated, then 1 slot is aggregated, and then 3 slots are aggregated.

[0117] In one embodiment of the time slot group in which the time slot group has a dynamic time slot group configuration, these time slot groups are non-overlapping and adjacent to each other. In another embodiment, when the time slot group has a dynamic time slot group configuration, these time slot groups are non-overlapping and may be non-adjacent to each other. This may allow power saving when an effective time slot group is not defined. In another embodiment in which the time slot group has a semi-static time slot group configuration, these time slot groups may be overlapping.

[0118] In one embodiment, the configuration of the slot group is signaled to the UE. In one embodiment, DCI signaling is used to signal the slot group configuration. For example, in one embodiment, in slot group N-1, DCI signaling is used to indicate the slot group configuration for slot group N. In one embodiment, the signaling is UE-specific signaling. For example, the UE-specific signaling is signaled in the GC-PDCCH. In one embodiment, the UE-specific signaling is sent in a UE-specific DCI.

[0119] In one embodiment, the UE receives configuration information and is configured to perform PDCCH monitoring for PDCCH MOs that can be set to occur on any OFDM symbol in a slot group with a gap. This enables any symbol within a slot group to contain a PDCCH MO (rather than the first X symbols or any X consecutive symbols as discussed above). In one embodiment, the locations of these MOs are based on symbols corresponding to beam pairs.

[0120] In one embodiment, all PDCCH monitoring opportunities may be located in any OFDM symbol of a slot group having a minimum time interval between a predetermined number (eg, 2) of consecutive transmissions of PDCCH. Fig.15 The position of the MO within the span is shown. Fig.15, X is the minimum number of OFDM symbols between the start of different PDCCH MOs, Y is the number of OFDM symbols within which a monitoring opportunity occurs, and Z is the slot group size. In one embodiment, the signaling of the location of the PDCCH is fixed (configured). In one embodiment, the signaling of the location of the PDCCH is signaled by L1. However, alternative signaling may be used.

[0121] In one embodiment, X and Y are based on the actual symbols of the time slot / time slot group. In another embodiment, X and Y are based on the symbols transmitted with the beams that allow communication with the UE. For example, X refers to the X symbols transmitted / received using a specific beam pair, and Y refers to the spacing based on the actual beam pair.

[0122] Unlike the PDCCH monitoring described above where (X,Y) is one of the sets (2,2), (4,3) or (7,3), in one embodiment, X, Y and Z are SCS and slot group size dependent.

[0123] In one embodiment, there is a minimum spacing between PDCCH MOs within a slot group. For example, in one embodiment, there is a minimum of at least 1 MO in each slot. Note that the distribution of PDCCH MOs can be uniform or non-uniform.

[0124] Fig.16 Three examples of the location of the MO are shown. Each of these examples is for an SCS of 960 kHz. Fig.16 , OFDM symbol 1601 shows an example where X is equal to 14, Y is equal to 3, Z is equal to 8, and offset is equal to 0, OFDM symbol 1602 shows an example where X is equal to 14, Y is equal to 3, Z is equal to 8, and offset is equal to 5, and OFDM symbol 1603 shows an example where X is equal to 8, Y is equal to 3, Z is equal to 8, and offset is equal to 0. Note that these examples are not meant to limit the techniques described herein to these specific values ​​of X, Y, Z, and offset.

[0125] Fig.17 An example of the location of the MO based on the symbols transmitted with the beams that allow communication with the UE is shown. Fig.17, OFDM symbol 1701 shows an example where X is equal to 2, Y is equal to 1, Z is not applicable (N / A), and the offset is N / A and the first effective beam in each slot group is used as the location of the PDCCH information, and OFDM symbol 1702 shows an example where X is equal to 3, Y is equal to 2, Z is equal to 2, and the offset is equal to 0 and the next symbol for the location of the PDCCH information among all subsequent symbols is 3 symbols away from the previous span (with an effective beam), the span length is 2, and the slot group length is 2. Note that these examples are not meant to limit the techniques described herein to these specific values ​​of X, Y, Z, and offset.

[0126] The configuration described above may be used in conjunction with having a position of an MO based on symbols transmitted with beams that allow communication with the UE. In one embodiment, the UE is configured to perform PDCCH monitoring on up to X (e.g., 3) symbols at the beginning of a scheduling unit that are transmitted with beams that allow communication with the UE, wherein the scheduling unit size is variable (e.g., 8 time slots). In another embodiment, the UE is configured to perform PDCCH monitoring on up to three symbols at the beginning of a scheduling unit, wherein the scheduling unit size is based on the position of symbols transmitted with beams that allow communication with the UE. In another embodiment, the UE is configured to perform PDCCH monitoring on up to three symbols at the beginning of a scheduling unit that are transmitted with beams that allow communication with the UE, wherein the scheduling unit size is based on the position of symbols transmitted with beams that allow communication with the UE.

[0127] In one embodiment, the UE is configured to perform PDCCH monitoring for any span of up to three symbols within a scheduling unit, which symbols are transmitted with beams that allow communication with the UE, wherein the scheduling unit size is variable (e.g., 8 time slots). In another embodiment, the UE is configured to perform PDCCH monitoring for any span of up to three symbols within a scheduling unit, wherein the scheduling unit size is based on the location of the symbols transmitted with beams that allow communication with the UE. In another embodiment, the UE is configured to perform PDCCH monitoring for any span of up to three symbols within a scheduling unit, which symbols are transmitted with beams that allow communication with the UE, wherein the scheduling unit size is based on the location of the symbols transmitted with beams that allow communication with the UE.
