[0002] This patent application claims priority to U.S. Provisional Patent Application No. 62 / 705,681, filed on July 10, 2020, entitled “PHYSICAL DOWNLINK CONTROLCHANNEL CANDIDATES AGGREGATED OVER DIFFERENT NUMBERS OF MONITORING OCCASIONS,” and U.S. Non-Provisional Patent Application No. 17 / 304,090, filed on July 14, 2021, entitled “PHYSICALDOWNLINK CONTROL CHANNEL CANDIDATES AGGREGATED OVER DIFFERENT NUMBERS OF MONITORING OCCASIONS,” which are hereby expressly incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications and techniques and apparatus for determining physical downlink control channel candidates aggregated over different numbers of monitoring occasions. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmission power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include multiple base stations (BSs) that may support communications for multiple user equipment (UEs). A UE may communicate with a BS via a downlink and an uplink. A "downlink" (or "forward link") refers to a communication link from a BS to a UE, while an "uplink" (or "reverse link") refers to a communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, etc.

[0006] The above-mentioned multiple access technologies have been adopted by various telecommunication standards to provide a common protocol that enables different user devices to communicate at the city, country, region and even global level. NR, also known as 5G, is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR aims to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP) (CP-OFDM) on the downlink, CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology and carrier aggregation, and better integration with other open standards. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0024] Various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. On the contrary, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. Based on the teachings of this article, it should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect disclosed herein, whether implemented independently of any other aspect of the present disclosure or implemented in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such a device or method, which uses other structures, functions, or structures and functions other than the various aspects of the present disclosure set forth herein or different from the various aspects of the present disclosure set forth herein to practice. It should be understood that any aspect of the disclosure disclosed herein can be embodied by one or more elements of the claims.

[0025] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and design constraints imposed on the overall system.

[0026] It should be noted that although aspects may be described herein using terminology generally associated with 5G or NR radio access technologies (RATs), aspects of the present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or RATs beyond 5G (e.g., 6G).

[0027] Figure 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, among other examples. The wireless network 100 may include a plurality of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE), and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0028] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access to UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access to UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access to UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown, BS 110a may be a macro BS of macro cell 102a, BS 110b may be a pico BS of pico cell 102b, and BS 110c may be a femto BS 102c of a femto cell. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0029] In some aspects, the cell may not necessarily be stationary, and the geographic area of ​​the cell may move depending on the location of the mobile BS. In some aspects, the BSs may be connected to each other and / or to one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces such as direct physical connections or virtual networks using any suitable transport network.

[0030] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the illustrated example, a relay BS 110d may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay BS may also be referred to as a relay station, a relay base station, a relay, or the like.

[0031] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0032] The network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other directly or indirectly via a wireless or wired backhaul.

[0033] UE 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or apparatus, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet), an entertainment device (e.g., a music or video device or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via wireless or wired media.

[0034] Some UEs may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors and / or location tags, which may communicate with a base station, another device (e.g., a remote device) or some other entity. For example, a wireless node may provide connectivity or connectivity to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Certain UEs may be considered as client equipment (CPE). UE 120 may be included in a housing that houses components of UE 120, such as a processor component and / or a memory component. In some aspects, a processor component and a memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operationally coupled, communicatively coupled, electronically coupled and / or electrically coupled.

[0035] Generally, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0036] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more side link channels. For example, UE 120 may use peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocol (e.g., which may include vehicle-to-vehicle (V2V) protocol or vehicle-to-infrastructure (V2I) protocol) and / or mesh network. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0037] The devices of the wireless network 100 can communicate using an electromagnetic spectrum, which can be subdivided into various categories, frequency bands, channels, etc. based on frequency or wavelength. For example, the devices of the wireless network 100 can communicate using an operating frequency band having a first frequency range (FR1), which can span from 410 MHz to 7.125 GHz, and / or can communicate using an operating frequency band having a second frequency range (FR2), which may range from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a frequency band "below 6 GHz". Similarly, although FR2 is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as "millimeter wave" by the International Telecommunication Union (ITU), FR2 is often referred to as a "millimeter wave" band. Therefore, unless otherwise explicitly stated, it should be understood that the term "below 6 GHz" and the like, if used herein, can broadly represent frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specifically stated, it should be understood that the term "millimeter wave" and the like, if used herein, can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0038] As mentioned above, Figure 1 are provided as examples. Other examples may differ from those described in Figure 1 The content described.

[0039] Figure 2 is a diagram illustrating an example 200 of a base station 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t and the UE 120 may be equipped with R antennas 252a through 252r, where in general T≥1 and R≥1.

[0040] At the base station 110, the transmit processor 220 may receive data from a data source 212 for one or more UEs, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, and, if applicable, may provide T output symbol streams to T modulators (MOD) 232a through 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0041] At the UE 120, antennas 252a to 252r may receive downlink signals from the base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. The MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 120 to the data receiver 260, and provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a channel quality indicator (CQI) parameter, among other examples. In some aspects, one or more components of UE 120 may be included in housing 284.

[0042] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 through the communication unit 294.

[0043] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or may be included in, one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, etc. The antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. The antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include a group of coplanar antenna elements and / or a group of non-coplanar antenna elements. The antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. The antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements coupled to one or more transmission and / or reception components (e.g. Figure 2 One or more antenna elements of one or more components).

[0044] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may also generate reference symbols for one or more reference signals. If applicable, the symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antennas 252, modulators and / or demodulators 254, MIMO detectors 256, receive processors 258, transmit processors 264, and / or TX MIMO processors 266. The transceiver may be comprised of a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (e.g., as described in reference to Figure 4-7 described).

[0045] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 if applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antennas 234, modulators and / or demodulators 232, MIMO detectors 236, receive processors 238, transmit processors 220, and / or TX MIMO processors 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (e.g., as described in reference to Figure 4-7 described).

[0046] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other components of the base station 110 may perform one or more techniques associated with determining PDCCH candidates aggregated over different numbers of monitoring occasions, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the can perform or direct e.g. Figure 6 The operation of process 600, Figure 7 , and / or operations of other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, conversion and / or interpretation), may cause one or more processors, UE 120 and / or base station 110 to perform or direct, for example Figure 6 The process of 600 Figure 7 The process 700 and / or operations of other processes as described herein. In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, among other examples.

[0047] In some aspects, the UE 120 may include means for receiving an indication of a set of aggregation levels of a PDCCH candidate set within a search space; means for determining a first subset of PDCCH candidates in each PDCCH candidate set aggregated within a single PDCCH monitoring opportunity, and a second subset of PDCCH candidates in each PDCCH candidate set aggregated across multiple PDCCH monitoring opportunities, etc. In some aspects, such means may include combining Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, etc.

[0048] In some aspects, a user equipment (UE) includes a unit for receiving an indication of an aggregation level set of a physical downlink control channel (PDCCH) candidate set within a search space; and / or a unit for decoding a first PDCCH candidate subset in each PDCCH candidate set aggregated within a single PDCCH monitoring opportunity, and a second PDCCH candidate subset in each PDCCH candidate set aggregated across multiple PDCCH monitoring opportunities. The unit for the user equipment (UE) to perform the operations described herein may include, for example, one or more of an antenna 252, a demodulator 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a modulator 254, a controller / processor 280, or a memory 282.

[0049] In some aspects, the base station includes a unit for sending an indication of a configuration of a search space having a first physical downlink control channel (PDCCH) candidate subset each aggregated within a single PDCCH monitoring opportunity and a second PDCCH candidate subset each aggregated across multiple PDCCH monitoring opportunities; and / or a unit for sending a PDCCH communication using a PDCCH candidate in the first PDCCH candidate subset or the second PDCCH candidate subset. The unit for the base station to perform the operations described herein may include, for example, one or more of a transmit processor 220, a TX MIMO processor 230, a modulator 232, an antenna 234, a demodulator 232, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0050] Although Figure 2 The blocks in the 200 are shown as distinct components, but the functions described above with respect to the blocks may be implemented in a single hardware, software, or combined component or 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 may be performed by or under the control of the controller / processor 280.

[0051] As mentioned above, providing Figure 2 As an example. Other examples may be related to Figure 2 Different than described.

[0052] Figure 3300 is a diagram illustrating an example resource structure 300 for wireless communication according to the present disclosure. Resource structure 300 shows examples of various resource groups described herein. As shown, resource structure 300 may include subframe 305. Subframe 305 may include multiple time slots 310. Although resource structure 300 is shown as including 2 time slots per subframe, a different number of time slots (e.g., 4 time slots, 8 time slots, 16 time slots, 32 time slots, etc.) may be included in a subframe. In some aspects, different types of transmission time intervals (TTIs) may be used instead of subframes and / or time slots. Time slot 310 may include multiple symbols 315, such as 7 symbols per time slot, 14 symbols per time slot, etc.

[0053] The potential control region of the time slot 310 may be referred to as a CORESET 320 and may be structured to support efficient use of resources, such as by flexible configuration or reconfiguration of resources of the CORESET 320 for one or more PDCCHs, one or more physical downlink shared channels (PDSCHs), etc. In some aspects, the CORESET 320 may occupy the first symbol 315 of the time slot 310, the first two symbols 315 of the time slot 310, the first three symbols 315 of the time slot 310, etc. Thus, the 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 the CORESET 320 may be flexibly configured, such as by Radio Resource Control (RRC) signaling to indicate the frequency domain region (e.g., the number of resource blocks) and / or the time domain region (e.g., a certain number of symbols) for the CORESET 320.

[0054] As shown, a symbol 315 including a CORESET 320 may include one or more control channel elements (CCEs) 325. Figure 3 As an example, two CCEs 325 are shown, which span a portion of the system bandwidth. The CCE 325 may include downlink control information (DCI) for providing control information for wireless communication. The base station may send 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. Figure 3 , an aggregation level of two is shown as an example, corresponding to two CCEs 325 in time slot 310. In some aspects, different aggregation levels may be used, such as 1, 4, 8, 16, etc.

[0055] Each CCE 325 may include a fixed number of resource element groups (REGs) 330. Figure 3In the example of FIG. 315 , four REGs 330 are shown, or a variable number of REGs 330 may be included. In some aspects, the number of REGs 330 included in a CCE 325 may be specified by a REG bundling 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 one subcarrier in the frequency domain and one OFDM symbol in the time domain.

[0056] The search space may include all possible locations where a PDCCH may be located (e.g., in time and / or frequency). CORESET320 may include one or more search spaces, such as a UE-specific search space, a group common search space, and / or a common search space. The search space may indicate a set of CCE positions where a UE can find a PDCCH that can potentially be used to send control information to the UE. The possible locations of the PDCCH may depend on whether the PDCCH is a UE-specific PDCCH (e.g., for a single UE) or a group common PDCCH (e.g., for multiple UEs), the aggregation level used, etc. The possible locations of the PDCCH (e.g., in time and / or frequency) may be referred to as PDCCH candidates, and the set of all possible PDCCH locations may be referred to as a search space. For example, the set of all possible PDCCH locations for a specific UE may be referred to as a UE-specific search space. Similarly, the set of all possible PDCCH locations across all UEs may be referred to as a common search space. The set of all possible PDCCH locations for a specific UE group may be referred to as a group common search space.

[0057] The CORESET 320 may be interleaved or non-interleaved. An interleaved CORESET 320 may have a CCE-to-REG mapping such that adjacent CCEs are mapped to dispersed REG bundles in the frequency domain (e.g., adjacent CCEs are not mapped to continuous REG bundles of the CORESET 320). A non-interleaved CORESET 320 may have a CCE-to-REG mapping such that all CCEs are mapped to continuous REG bundles of the CORESET 320 (e.g., in the frequency domain).

[0058] As mentioned above, Figure 3 are provided as examples. Other examples may differ from those described in Figure 3 The content described.

[0059] The base station may configure a PDCCH candidate set at a single PDCCH monitoring opportunity or multiple monitoring opportunities. In other words, the PDCCH candidate set may include CCEs located only within the signal PDCCH monitoring opportunity, or may include CCEs located within a first PDCCH monitoring opportunity and CCEs located within a second PDCCH monitoring opportunity. In some examples, the base station may send a group-common DCI that activates a preconfigured monitoring aggregation level (e.g., a repeated PDCCH monitoring opportunity group for the same PDCCH). However, the group-common DCI that activates the preconfigured PDCCH monitoring aggregation level may instruct all UEs receiving the group-common DCI to search for all PDCCH candidates aggregated on the same number of PDCCH monitoring opportunities. For UEs with good reception conditions, using aggregated PDCCH monitoring opportunities for all PDCCH candidates may unnecessarily consume communication resources.

[0060] In some aspects described herein, a network (e.g., via a base station) may define a first PDCCH candidate subset and a second PDCCH candidate subset. The first PDCCH candidate subset may include PDCCH candidates that are each aggregated (e.g., with multiple CCEs) within a single PDCCH monitoring opportunity. The second PDCCH candidate subset may include PDCCH candidates that are each aggregated across multiple PDCCH monitoring opportunities.

[0061] In some aspects, the UE may determine, at least in part based on the aggregation level of the PDCCH candidates, whether the PDCCH candidate is assigned to a first subset of PDCCH candidates aggregated on a single PDCCH monitoring opportunity or to a second subset of PDCCH candidates aggregated on multiple PDCCH monitoring opportunities. In some aspects, the UE may determine an aggregation level threshold (e.g., via signaling from a base station, a communication standard, etc.) for determining whether the PDCCH candidate is assigned to the first subset of PDCCH candidates or the second subset of PDCCH candidates. For example, based at least in part on a PDCCH candidate having an aggregation level that satisfies the aggregation level threshold, the PDCCH candidate may be assigned to a second subset of PDCCH candidates aggregated on multiple PDCCH monitoring opportunities.

[0062] Based at least in part on the UE monitoring certain PDCCH candidates within a single PDCCH monitoring opportunity and monitoring other PDCCH candidates within multiple PDCCH monitoring opportunities, the UE can save computing, communication, network, and power resources by using a single PDCCH monitoring opportunity to receive PDCCH messages when appropriate (e.g., based at least in part on channel conditions) and using multiple PDCCH monitoring opportunities to receive PDCCH messages when appropriate. For example, a UE with a signal-to-interference-plus-noise ratio (SINR) that meets a threshold may be able to receive PDCCH messages within a single PDCCH monitoring opportunity and not have the coverage benefits (e.g., repetition, time diversity, etc.) of receiving PDCCH messages within multiple PDCCH monitoring opportunities. Based at least in part on receiving a PDCCH message within a single PDCCH monitoring opportunity, the UE can ignore other PDCCH monitoring opportunities.

[0063] Figure 4 4 is a diagram illustrating an example 400 associated with determining PDCCH candidates aggregated over different numbers of monitoring occasions according to the present disclosure. Figure 4 As shown, a UE (e.g., UE 120) can communicate with a base station (e.g., base station 110). The UE and the base station can be part of a wireless network (e.g., wireless network 100).

[0064] As indicated by reference numeral 405, the base station may send configuration information and the UE may receive the configuration information. In some aspects, the UE may receive the configuration information from another device (e.g., from another base station, another UE, etc.), from a specification of a communication standard, etc. In some aspects, the UE may receive the configuration information via one or more of radio resource control (RRC) signaling, media access control (MAC) signaling (e.g., MAC control element (MAC CE)), etc. In some aspects, the configuration information may include an indication of one or more configuration parameters for selection by the UE (e.g., known to the UE), explicit configuration information for the UE to use to configure the UE, etc.

[0065] In some aspects, the configuration information may indicate that the UE is to determine a first subset of PDCCH candidates and a second subset of PDCCH candidates, wherein the first subset of PDCCH candidates are each aggregated within a single PDCCH monitoring opportunity and the second subset of PDCCH candidates are each aggregated across multiple PDCCH monitoring opportunities. In some aspects, the configuration information may provide information for determining the first subset and the second subset (e.g., determining whether a particular PDCCH candidate is assigned to the first subset or the second subset), such as an indication of an aggregation level threshold. The UE may identify PDCCH candidates to be aggregated within a single PDCCH monitoring opportunity (e.g., the first subset of PDCCH candidates) and PDCCH candidates to be aggregated across multiple PDCCH monitoring opportunities (e.g., the second subset of PDCCH candidates) based at least in part on the information (e.g., the indication of the aggregation threshold).

[0066] In some aspects, the configuration information may indicate that the UE is to determine the aggregation threshold based at least in part on one or more parameters of the CORESET including the PDCCH candidate set. For example, the configuration information may indicate that the UE is to determine the aggregation threshold based at least in part on the frequency range of the CORESET, the frequency band of the CORESET, the subcarrier spacing of the CORESET, the number of symbols of the CORESET, the number of resources of the CORESET (e.g., CCE, resource block, REG, etc.), etc.

[0067] In some aspects, the configuration information may indicate that the UE is to determine the aggregation threshold based at least in part on an indication within a search space configuration associated with a PDCCH candidate set, an explicit indication within dynamic signaling (e.g., UE-specific DCI or MAC CE, group common DCI or MAC CE, etc.), an implicit indication within dynamic signaling (e.g., an indication of coverage enhancement, an indication of monitoring aggregation, etc.), etc.

[0068] As indicated by reference numeral 410, the UE may configure the UE to communicate with one or more base stations. In some aspects, the UE may configure the UE based at least in part on the configuration information. In some aspects, the UE may be configured to perform one or more operations described herein.

[0069] As indicated by reference numeral 415, the UE may receive, and the base station may send, an indication of a set of aggregation levels for a set of PDCCH candidates within a search space. For example, the UE may receive an indication of a search space configuration. The indication may identify a known search space configuration (e.g., an indication of a previously received search space configuration), an explicit description of the search space configuration, etc.

[0070] As indicated by reference numeral 420, the UE may receive an indication of an aggregation threshold, and the base station may send the indication of the aggregation threshold. In some aspects, the indication of the aggregation threshold may be received in the same message as an indication of a set of aggregation levels (e.g., a search space configuration message), configuration information, etc. In some aspects, the UE may receive the indication of the aggregation threshold via dynamic signaling (e.g., a DCI message, one or more MAC CEs, etc.), RRC signaling (e.g., a configured grant), etc.

[0071] In some aspects, the indication may be an explicit indication or an implicit indication. For example, the indication may be an explicit indication within dynamic signaling, such as a UE-specific or group-common DCI message or one or more MAC CEs. The indication may be an implicit indication within dynamic signaling, such as an indication of coverage enhancement, an indication of monitoring aggregation, etc.

[0072] As indicated by reference numeral 425, the UE may determine a first PDCCH candidate subset and a second PDCCH candidate subset. In some aspects, the UE may determine the first PDCCH candidate subset and the second PDCCH candidate subset based at least in part on an indicated aggregation level of each of the first PDCCH candidate subset and the second PDCCH candidate subset. The UE may determine the second PDCCH candidate subset based at least in part on each PDCCH candidate of the second PDCCH candidate subset having an aggregation level that satisfies an aggregation level threshold.

[0073] In some aspects, the UE may determine the aggregation level threshold based at least in part on an indication of the aggregation level threshold, configuration information, a search space configuration, etc. In some aspects, the UE may determine the aggregation level threshold based at least in part on a definition based at least in part on the configuration information, a frequency range of a control resource set (CORESET) including a PDCCH candidate set, a frequency band of the CORESET, a subcarrier spacing of the CORESET, a number of symbols of the CORESET, a number of resources of the CORESET, etc.

[0074] In some aspects, one or more CCEs may be allocated to both a PDCCH candidate in the first PDCCH candidate subset and a PDCCH candidate in the second PDCCH candidate subset. In some aspects, one or more PDCCH candidates in the first PDCCH candidate subset may be aggregated within a first PDCCH monitoring opportunity, and one or more PDCCH candidates in the first PDCCH candidate subset may be aggregated within a second PDCCH monitoring opportunity.

[0075] As indicated by reference numeral 430, the UE may receive downlink communications including a PDCCH candidate set (e.g., including a first PDCCH candidate subset and a second PDCCH candidate subset), and the base station may send the downlink communications. In some aspects, the UE may receive downlink communications based at least in part on a CORESET configuration, a previously received grant (e.g., a dynamic grant, a configured grant, etc.), etc.

[0076] As indicated by reference numeral 435, the UE may monitor a PDCCH candidate set for PDCCH communication. For example, the UE may monitor the PDCCH candidate set within a single PDCCH monitoring opportunity in the search space (e.g., for a first PDCCH candidate subset) and within multiple PDCCH monitoring opportunities in the search space (e.g., for a second PDCCH candidate subset).

[0077] Based at least in part on the UE monitoring a first subset of PDCCH candidates within a single PDCCH monitoring opportunity and monitoring a second subset of PDCCH candidates within multiple PDCCH monitoring opportunities, the UE may save computational, communication, network, and power resources by using a single PDCCH monitoring opportunity to receive a PDCCH message when appropriate (e.g., based at least in part on channel conditions) and using multiple PDCCH monitoring opportunities to receive a PDCCH message when appropriate.

[0078] As mentioned above, providing Figure 4 As an example. Other examples may be related to Figure 4 Different than described.

[0079] Figure 5 is a diagram illustrating an example 500 associated with determining PDCCH candidates aggregated over different numbers of monitoring occasions according to the present disclosure.

[0080] like Figure 5 As shown, the CORESET may include a first PDCCH monitoring opportunity 505 and a second PDCCH monitoring opportunity 510. In some aspects, the two PDCCH monitoring opportunities 505 and 510 may be within one slot of a subframe.

[0081] The first PDCCH monitoring opportunity 505 may include two CCEs associated with the first PDCCH candidate 515. The first PDCCH monitoring opportunity 505 may include a single CCE associated with the second PDCCH candidate 520. The second PDCCH monitoring opportunity 510 may include four CCEs associated with the third PDCCH candidate 525.

[0082] The first PDCCH monitoring opportunity 505 may include a first portion 530 (e.g., one or more CCEs) of the fourth PDCCH candidate 540, and the second PDCCH monitoring opportunity 510 may include a second portion 535 of the fourth PDCCH candidate 540. In other words, the first PDCCH candidate 515, the second PDCCH candidate 520, and the third PDCCH candidate 525 may be assigned to a first PDCCH candidate subset aggregated within a single PDCCH monitoring opportunity, and the fourth PDCCH candidate 540 may be assigned to a second PDCCH candidate subset aggregated across two PDCCH monitoring opportunities 505 and 510.

[0083] As mentioned above, providing Figure 5 As an example. Other examples may differ from Figure 5 Examples described.

[0084] Figure 6 is a diagram illustrating an example process 600 performed, for example, by a UE in accordance with the present disclosure. Example process 600 is an example in which a UE (eg, UE 120, etc.) performs operations associated with PDCCH candidates aggregated over different numbers of monitoring occasions.

[0085] like Figure 6 As shown, in some aspects, process 600 may include receiving an indication of a set of aggregation levels for a set of PDCCH candidates within a search space (block 610). For example, a UE (e.g., using receive processor 258, controller / processor 280, memory 282, etc.) may receive an indication of a set of aggregation levels for a set of PDCCH candidates within a search space, as described.

[0086] like Figure 6 As further shown in , in some aspects, process 600 may include decoding a first subset of PDCCH candidates in each set of PDCCH candidates aggregated within a single PDCCH monitoring opportunity and a second subset of PDCCH candidates in each set of PDCCH candidates aggregated across multiple PDCCH monitoring opportunities (block 620). For example, the UE (e.g., using receive processor 258, controller / processor 280, memory 282, etc.) may decode a first subset of PDCCH candidates in each set of PDCCH candidates aggregated within a single PDCCH monitoring opportunity and a second subset of PDCCH candidates in each set of PDCCH candidates aggregated across multiple PDCCH monitoring opportunities, as described above.

[0087] Process 600 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in combination with one or more other processes described elsewhere herein.

[0088] In a first aspect, process 600 includes monitoring a first subset of PDCCH candidates within a single PDCCH monitoring occasion and monitoring a second subset of PDCCH candidates over multiple PDCCH monitoring occasions.

[0089] In a second aspect, alone or in combination with the first aspect, decoding the first PDCCH candidate subset and the second PDCCH candidate subset includes determining the first PDCCH candidate subset and the second PDCCH candidate subset based at least in part on an indicated aggregation level of each PDCCH candidate in the first PDCCH candidate subset and each PDCCH candidate in the second PDCCH candidate subset.

[0090] In a third aspect, alone or in combination with one or more of the first and second aspects, the second PDCCH candidate subsets have aggregation levels each satisfying an aggregation level threshold.

[0091] In a fourth aspect, alone or in combination with one or more of the first to third aspects, the aggregation level threshold is based at least in part on one or more of the following: at least in part on a definition of the configuration information, a frequency range of the CORESET including the PDCCH candidate set, a frequency band of the CORESET, a subcarrier spacing of the CORESET, a number of symbols of the CORESET, or a number of resources of the CORESET.

[0092] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, process 600 includes determining an aggregation level threshold based at least in part on one or more of: a search space configuration, RRC signaling, a DCI message, or one or more MAC CEs.

[0093] In a sixth aspect, alone or in combination with one or more of the first to fifth aspects, process 600 includes determining an aggregation level threshold based at least in part on one or more of an implicit indication or an explicit indication of the aggregation level threshold.

[0094] In the seventh aspect, alone or in combination with one or more of the first to sixth aspects, the first PDCCH candidate in the first PDCCH candidate subset includes a first CCE set for a first PDCCH monitoring opportunity; and the second PDCCH candidate in the second PDCCH candidate subset includes a first CCE set for the first PDCCH monitoring opportunity and a second CCE set for the second PDCCH monitoring opportunity.

[0095] Although Figure 6 Example blocks of process 600 are shown, but in some aspects, process 600 may include more Figure 6More blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in the process 600. Additionally or alternatively, two or more blocks of process 600 may be performed in parallel.

[0096] Figure 7 is a diagram illustrating an example process 700 performed, for example, by a base station in accordance with the present disclosure. Example process 700 is an example in which a base station (eg, base station 110) performs operations associated with physical downlink control channel candidates aggregated over different numbers of monitoring occasions.

[0097] like Figure 7 As shown, in some aspects, process 700 may include sending an indication of a configuration of a search space having a first subset of PDCCH candidates each aggregated within a single PDCCH monitoring opportunity and a second subset of PDCCH candidates each aggregated across multiple PDCCH monitoring opportunities (block 710). For example, a base station (e.g., using controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232 and / or antenna 234, etc.) may send an indication of a configuration of a search space having a first subset of PDCCH candidates each aggregated within a single PDCCH monitoring opportunity and a second subset of PDCCH candidates each aggregated across multiple PDCCH monitoring opportunities, as described above.

[0098] like Figure 7 As further shown, in some aspects, process 700 may include transmitting a PDCCH communication using a PDCCH candidate from the first PDCCH candidate subset or the second PDCCH candidate subset (block 720). For example, the base station (using controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, and / or antenna 234, etc.) may transmit a PDCCH communication using a PDCCH candidate from the first PDCCH candidate subset or the second PDCCH candidate subset, as described above.

[0099] Process 700 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in combination with one or more other processes described elsewhere herein.

[0100] In a first aspect, a PDCCH candidate is associated with a first subset of PDCCH candidates or a second subset of PDCCH candidates based at least in part on an aggregation level of the PDCCH candidates.

[0101] In a second aspect, alone or in combination with the first aspect, the second PDCCH candidate subsets have aggregation levels each satisfying an aggregation level threshold.

[0102] In a third aspect, either alone or in combination with one or more of the first and second aspects, the aggregation level threshold is based at least in part on one or more of the following: based at least in part on a definition of the configuration information, a frequency range of the CORESET including the PDCCH candidate set, a frequency band of the CORESET, a subcarrier spacing of the CORESET, a number of symbols of the CORESET, or a number of resources of the CORESET.

[0103] In a fourth aspect, alone or in combination with one or more of the first to third aspects, process 700 includes sending an indication of an aggregation level threshold based at least in part on a search space configuration, RRC signaling, a DCI message, or one or more of one or more MAC CEs.

[0104] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, process 700 includes sending an indication of an aggregation level threshold based at least in part on one or more of an implicit indication or an explicit indication of the aggregation level threshold.

[0106] Although Figure 7 Example blocks of process 700 are shown, but in some aspects, process 700 may include more Figure 7 More blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in the process 700. Additionally or alternatively, two or more blocks of process 700 may be performed in parallel.
