Description

Technical Field

[0001] Various aspects of this disclosure generally relate to wireless communication and techniques and apparatus for repeated specific cyclic shifts for non-interleaved control resource sets. Background Technology

[0002] Wireless communication systems are widely deployed to provide various telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that enable communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, and / or similar resources). 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 issued by the 3rd Generation Partnership Project (3GPP).

[0003] A wireless communication network may include multiple base stations (BSs) capable of supporting communication for multiple user equipments (UEs). UEs can communicate with base stations (BSs) via downlinks and uplinks. A downlink (or forward link) refers to the communication link from the BS to the UE, while an uplink (or backward link) refers to the communication link from the UE to the 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, and / or the like.

[0004] To provide a common protocol enabling different user equipment to communicate at the city, national, regional, and even global levels, the aforementioned multiple access technologies have been adopted in various telecommunications standards. New Radio (NR), also known as 5G, is a set of enhancements to the LTE mobile standard issued by the 3rd Generation Partnership Project (3GPP). NR is designed to better support mobile broadband internet access by improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and using Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) on the downlink (DL) (CP-OFDM), using CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation for better integration with other open standards. However, with the continued increase in demand for mobile broadband access, there is a need for further improvements to LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunications standards that employ these technologies. Summary of the Invention

[0005] In some aspects, a method for performing wireless communication by a user equipment (UE) may include determining a cyclic shift configuration for one or more repetitions of a non-interleaved control resource set (CORESET); and monitoring one or more physical downlink control channel (PDCCH) candidates in one or more repetitions of the non-interleaved CORESET, based at least in part on the determination of the cyclic shift configuration for one or more repetitions.

[0007] In some aspects, a UE for wireless communication may include a memory and one or more processors operatively coupled to the memory. The memory and the one or more processors may be configured to determine a cyclic shift configuration for one or more repetitions of a non-interleaved CORESET; and to monitor one or more PDCCH candidates in one or more repetitions of a non-interleaved CORESET, at least in part based on the determination of the cyclic shift configuration for one or more repetitions.

[0009] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication. When executed by one or more processors of the UE, the one or more instructions may enable the one or more processors to determine a cyclic shift configuration for one or more repetitions of a non-interleaved CORESET; and to monitor one or more PDCCH candidates in one or more repetitions of the non-interleaved CORESET based at least in part on the determination of the cyclic shift configuration for one or more repetitions.

[0010] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication.

[0024] Various aspects of this disclosure are described below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be exhaustive and complete, and to convey the scope of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of the disclosure, whether implemented independently of or in combination with any other aspect of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or practice. Additionally, the scope of this disclosure is intended to cover an apparatus or method practiced using structures, functions, or structures and functions other than those set forth herein. It should be understood that any aspect of this disclosure disclosed herein may be embodied by one or more elements of the claims.

[0025] Several aspects of a telecommunications system will now be presented with reference to various devices and technologies. These devices and technologies will be described in detail below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, “elements”). These elements can be implemented using hardware, software, or a combination thereof. Whether such an element is implemented as hardware or software depends on the specific application and the design constraints imposed on the entire system.

[0026] It should be noted that although terms commonly associated with 3G and / or 4G wireless technologies may be used to describe aspects herein, the aspects of this disclosure may be applied to other generation-based communication systems, such as 5G and later technologies, including NR technology.

[0027] Figure 1This is a diagram illustrating a wireless network 100 in which various aspects of this disclosure may be practiced. Network 100 may be an LTE network or some other wireless network, such as a 5G or NR network. Wireless network 100 may include multiple BS 110s (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, Node B, gNB, 5G Node B (NB), access point, Transmit / Receive Point (TRP), and / or the like. Each BS may provide communication coverage for a specific geographic area. In 3GPP, depending on the context in which the term is used, the term "cell" may refer to the coverage area of ​​a BS and / or the BS subsystem serving that coverage area.

[0028] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access for UEs with service subscriptions. A picocell can cover a relatively small geographic area and can allow unrestricted access for UEs with service subscriptions. A femtocell can cover a relatively small geographic area (e.g., a home) and can allow restricted access for UEs associated with the femtocell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS used for macrocells can be called a macro BS. A BS used for picocells can be called a pico BS. A BS used for femtocells can be called a femto BS or a home BS. Figure 1 In the example shown, BS 110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for pico cell 102b, and BS 110c can be a femto BS for femto cell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “Node B,” “5G NB,” and “cell” are used interchangeably herein.

[0029] In some respects, the cell is not necessarily fixed, and the geographical area of ​​the cell can move depending on the location of the mobile BS. In some respects, BSs can interconnect with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (such as direct physical connections, virtual networks, and / or similar devices 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 transmit the data transmissions to a downstream station (e.g., a UE or a BS). A relay station can also be a UE that can relay the transmissions of other UEs. Figure 1 In the example shown, relay station 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay station may also be referred to as a relay BS, relay base station, repeater, and / or the like.

[0031] Wireless network 100 can be a heterogeneous network containing different types of Base Stations (BSs), such as macro BSs, pico BSs, femto BSs, relay BSs, and / or the like. These different types of BSs can have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs can have higher transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0032] Network controller 130 can be coupled to a group of base stations (BSs) and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via backhaul. The BSs can also communicate with each other directly or indirectly, for example, via wireless or wired backhaul.

[0033] UEs 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be fixed or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, and / or the like. A UE may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smart notebook, an ultrabook, a medical device or equipment, a biosensor / device, a wearable device (smartwatch, smart clothing, smart glasses, smart bracelet), smart jewelry (e.g., a smart ring, a 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, industrial manufacturing equipment, a GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0034] Some UEs can be considered 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, instruments, monitors, location tags, and / or the like, which can communicate with a base station, another device (e.g., a remote device), or some other entity. For example, a wireless node can provide or provide 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 can be considered Internet of Things (IoT) devices and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered Customer Premises Equipment (CPE). UE 120 can be included within a housing that houses the components of UE 120 (such as processor components, memory components, etc.). In some aspects, the processor components and memory components can be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, electrically coupled, etc.

[0035] Typically, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific Radio Access Technology (RAT) and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, air interface, and / or the like. A frequency can also be referred to as a carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0036] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary for communication with each other). For example, UE 120 may use point-to-point (P2P) communication, device-to-device (D2D) communication, vehicular wireless communication (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, and / or the like), mesh networks, and / or the like. 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] As mentioned above, Figure 1 This is provided as an example. Other examples may be related to... Figure 1 The examples described are different.

[0038] Figure 2A block diagram of design 200 for base station 110 and UE 120 is shown, which can be Figure 1 One of the base stations and one of the UEs. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, wherein typically T≥1 and R≥1.

[0039] At base station 110, transmitting processor 220 can receive data from data source 212 of one or more UEs, select one or more modulation and decoding schemes (MCS) for each UE based at least in part on channel quality indicators (CQI) received from the UE, process (e.g., encode and modulate) data for each UE based at least in part on the selected MCS(one or more) for the UE, and provide data symbols for all UEs. Transmitting processor 220 can also process system information (e.g., for semi-static resource partitioning information (SRPI) and / or the like) and control information (e.g., CQI requests, grants, upper-layer signaling, and / or the like), and provide overhead symbols and control symbols. Transmitting processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols (if applicable), and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can process its respective output symbol stream (e.g., for OFDM and / or the like) to obtain an output sample stream. Each modulator 232 can 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 to 232t can be transmitted separately via T antennas 234a to 234t. Position coding can be used to generate synchronization signals to convey additional information, according to various aspects described in more detail below.

[0040] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations, and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can adjust (e.g., filter, amplify, down-convert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM, etc.) to obtain the received symbols. MIMO detector 256 can obtain the received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide the detected symbols. Receiver processor 258 can process (e.g., demodulate and decode) the detected symbols, provide the decoded data for UE 120 to data sink 260, and provide the decoded control information and system information to controller / processor 280. The channel processor can determine the Reference Received Power (RSRP), Received Signal Strength Indicator (RSSI), Reference Received Quality (RSRQ), Channel Quality Indicator (CQI), and / or the like. In some aspects, one or more components of the UE 120 may be contained within a housing.

[0041] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, for example, in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0042] In the uplink, at UE 120, the transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting including RSRP, RSSI, RSRQ, CQI, and / or the like). The transmit processor 264 can also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 can be pre-encoded (if applicable) by the TX MIMO processor 266, then further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to base station 110. In some aspects, UE 120 includes a transceiver. The transceiver may include (one or more) antennas 252, modulators and / or demodulators 254, MIMO detectors 256, receive processors 258, transmit processors 264, and / or any combination of the TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein, for example, as referenced. Figures 4-8 As described.

[0043] At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if applicable), and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and communicate with network controller 130 via communication unit 244. In some aspects, base station 110 includes a transceiver. The transceiver may include (one or more) antenna 234, modulator and / or demodulator 232, MIMO detector 236, receiver processor 238, transmitter processor 220, and / or TX MIMO processor 230, or any combination thereof. 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, for example, as referenced. Figures 4-8 As described.

[0044] As described in more detail elsewhere in this document, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component(s) may perform one or more techniques associated with repeated specific cyclic shifts of the non-interleaved control resource set (CORESET). For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component(s) can perform or direct, for example Figure 7 The process 700 Figure 8 The operation of process 800 and / or other processes described herein. Memory 242 and 282 may store data and program code 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 for storing one or more instructions for wireless communication. For example, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly or after compilation, translation, interpretation, and / or similar operations), one or more instructions may execute or direct, for example... Figure 7 The process 700 Figure 8 The operation of process 800 and / or other processes described herein. In some aspects, the execution instructions may include run instructions, conversion instructions, compilation instructions, interpretation instructions, etc. Scheduler 246 may schedule the UE to perform data transmission on the downlink and / or uplink.

[0045] In some aspects, UE 120 may include components for determining a cyclic shift configuration for one or more repetitions of a non-interleaved CORESET; components for monitoring one or more physical downlink control channel (PDCCH) candidates in one or more repetitions of a non-interleaved CORESET, at least in part based on determining the cyclic shift configuration for one or more repetitions. In some aspects, such components may include combinations of Figure 2 One or more components of the described UE 120, 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.

[0046] In some aspects, base station 110 may include components for determining a cyclic shift configuration for one or more repetitions of a non-interleaved CORESET; components for transmitting one or more PDCCH candidates in one or more repetitions of a non-interleaved CORESET based at least in part on the determined cyclic shift configuration for one or more repetitions. In some aspects, such components may include combinations of... Figure 2 One or more components of the described base station 110, such as antenna 234, DEMOD 232, MIMO detector 236, receiver processor 238, controller / processor 240, transmitter processor 220, TX MIMO processor 230, MOD 232, antenna 234, etc.

[0047] As mentioned above, Figure 2 This is provided as an example. Other examples may be related to... Figure 2 The examples described are different.

[0048] Figure 3 This is a diagram illustrating an example resource structure 300 for wireless communication according to various aspects of this disclosure. Resource structure 300 shows examples of various resource groups described herein. As shown, resource structure 300 may include subframes 305. Subframes 305 may include multiple time slots 310. Although resource structure 300 is shown to include 2 time slots per subframe, subframes may include different numbers of time slots (e.g., 4 time slots, 8 time slots, 16 time slots, 32 time slots, etc.). In some aspects, different types of transmission time intervals (TTIs) may be used in addition to subframes and / or time slots. Time slots 310 may include multiple symbols 315, such as 7 symbols or 14 symbols per time slot.

[0049] The potential control area of ​​time slot 310 can be referred to as CORESET 320 and can be configured to support efficient use of resources, such as by flexibly configuring or reconfiguring the resources of CORESET 320 for one or more PDCCHs, one or more Physical Downlink Shared Channels (PDSCHs), etc. In some aspects, CORESET 320 may occupy the first symbol 315 of time slot 310, the first two symbols 315 of time slot 310, or the first three symbols 315 of time slot 310. Therefore, CORESET 320 may include multiple resource blocks (RBs) in the frequency domain and one, two, or three symbols 315 in the time domain. In 5G, the number of resources included in CORESET 320 can be flexibly configured, for example, by using Radio Resource Control (RRC) signaling to indicate the frequency domain area (e.g., the number of resource blocks) and / or time domain area (e.g., the number of symbols) of CORESET 320.

[0050] As shown in the figure, symbol 315, including CORESET 320, may include one or more Control Channel Elements (CCEs) 325, for example, shown as two CCEs 325, spanning a portion of the system bandwidth. CCEs 325 may include downlink control information (DCI) for providing control information for wireless communication. The base station may transmit DCI during multiple CCEs 325 (as shown in the figure), where the number of CCEs 325 used for DCI transmission represents the aggregation level (AL) of the BS for DCI transmission. Figure 3 In this example, two aggregation levels correspond to two CCE 325s in slot 310. In some aspects, different aggregation levels can be used, such as 1, 4, 8, 16 and / or similar levels.

[0051] Each CCE 325 may include a fixed number of resource element groups (REGs) 330, shown as four REGs 330, or may include a variable number of REGs 330. In some aspects, the number of REGs 330 included in a CCE 325 may be specified by the REG bundle size. A REG 330 may include a resource block that 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.

[0052] The search space can be all possible locations where the PDCCH might be located (e.g., in time and / or frequency). CORESET 320 can 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 can indicate a set of CCE locations where the UE can find a PDCCH that might be used to send control information to the UE. Possible locations of the PDCCH can 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 being used, and / or the like. Possible locations of the PDCCH (e.g., in time and / or frequency) can be referred to as PDCCH candidates, and the set of all possible PDCCH locations can be referred to as the search space. For example, the set of all possible PDCCH locations for a specific UE can be referred to as a UE-specific search space. Similarly, the set of all possible PDCCH locations across all UEs can be referred to as a common search space. The set of all possible PDCCH locations for a specific group of UEs can be referred to as a group common search space.

[0053] In order to decode PDCCH, a UE may need the PDCCH to use a specific aggregation level (e.g., including a specific number of CCEs). For example, a UE with reduced capacity and / or located at the cell edge may not be able to decode a PDCCH using an aggregation level below a threshold.

[0054] CORESETs can be interleaved or non-interleaved. An interleaved CORESET can include a CCE-to-REG mapping that maps adjacent CCEs to scattered REG bundles in the frequency domain (e.g., adjacent CCEs may not map to consecutive REG bundles in the CORESET). A non-interleaved CORESET can include a CCE-to-REG mapping that maps all CCEs to consecutive REG bundles in the CORESET (e.g., in the frequency domain).

[0055] In particular, different types of UEs can operate within the cells provided by the BS. For example, the BS can provide network services to advanced UEs (which may be referred to as traditional UEs or high-layer UEs), NR-Light (or NR-Lite) UEs (which may be referred to as low-layer UEs), and so on. An advanced UE can be a UE associated with a receive bandwidth capacity above a certain threshold in the receive downlink signal / channel (e.g., bandwidth greater than or equal to 100 MHz). Conversely, an NR-Light UE can be a UE with a bandwidth capacity below a certain threshold in the receive downlink signal / channel (e.g., bandwidth less than 10 MHz, less than 5 MHz, etc.). Furthermore, an NR-Light UE can have fewer receive antennas or lower computing or storage capacity than an advanced UE.

[0056] Therefore, NR-Light UEs with reduced capacity (e.g., fewer receive antennas, reduced bandwidth capacity, etc.) may be unable to decode PDCCHs below a certain aggregation level. However, due to the reduced capacity of NR-Light UEs, they may not be able to be configured with CORESETs that include a number of resource blocks that would allow for higher aggregation levels. Therefore, in some cases, extending the CORESET by using multiple repetitions of the CORESET can include more resource blocks. In some cases, such extended CORESETs may be interleaved CORESETs. However, due to the reduced bandwidth capacity of the UE, the UE (e.g., NR-Light UE) may not be able to handle certain interleaved CORESETs (e.g., interleaved CORESETs may require extended bandwidth based on the CCE of interleaved CORESETs mapped to REG bundles scattered in the frequency domain).

[0057] Some of the techniques and apparatus described herein enable the implementation of repeated specific cyclic shifts for non-interleaved cores. For example, it allows the UE and / or base station to determine a cyclic shift configuration for one or more repetitions of a non-interleaved core. Therefore, spatial diversity can be increased through the repetition of non-interleaved cores, thereby improving the channel estimation parameters of the PDCCH. This can improve the performance of the PDCCH (e.g., for NR-Light UEs).

[0058] As mentioned above, Figure 3 This is provided as an example. Other examples may be related to... Figure 3 The examples described are different.

[0059] Figure 4 This is a diagram illustrating example 400 of a non-interleaved CORESET repeating a specific cyclic shift according to various aspects of this disclosure. Figure 4 As shown, base station 110 and UE 120 can communicate with each other using PDCCH communication. In some aspects, UE 120 may be an NR-Light UE, such as a wearable device, Internet of Things (IoT) device, sensor, camera, etc., which is associated with limited bandwidth, power capacity, transmission range, etc. For example, UE 120 may have a number of receive antennas that meet (e.g., below) a threshold and / or a bandwidth capacity that meets (e.g., less than) a threshold.

[0060] like Figure 4 As shown, and by reference numeral 405, base station 110 can determine the cyclic shift configuration to be used for non-interleaved CORESET (e.g., base station 110 to send one or more repeated non-interleaved CORESETs to UE 120 on one or more PDCCH candidates).

[0061] As shown by reference numeral 410 in the attached figure, base station 110 can transmit a defined cyclic shift configuration, and UE 120 can receive the defined cyclic shift configuration. For example, base station 110 can transmit the cyclic shift configuration in PDCCH configuration, CORESET configuration, etc. Base station 110 can transmit the cyclic shift configuration via RRC signaling. As described below, in some aspects, such as when the cyclic shift configuration is determined by UE 120 in another manner, base station 110 may not transmit the cyclic shift configuration to UE 120.

[0062] As shown by reference numeral 415 in the attached figure, UE 120 can determine the cyclic shift configuration to be used for non-interleaved CORESETs (e.g., non-interleaved CORESETs where base station 110 sends one or more PDCCH repetitions to UE 120 on one or more PDCCH candidates). In some aspects, the cyclic shift configuration can identify the cyclic shift index (e.g., the ShiftIndex parameter) for the non-interleaved CORESET (e.g., the index of REGs, resource blocks, REG bundles, etc., according to which the REG bundles of the non-interleaved CORESET will be cyclically shifted). In some aspects, the cyclic shift configuration can identify the frequency domain cyclic shift of one or more REG bundles for the non-interleaved CORESET (e.g., identifying the cyclic shift according to the number of REG bundles), as follows regarding... Figure 5 As stated above.

[0063] In some aspects, the uninterleaved coreset can (e.g., by base station 110) be encoded with multiple decoded bits corresponding to the PDCCH (e.g., multiple bits of the uninterleaved coreset can be encoded by the PDCCH channel code to form the PDCCH decoded bits). In some aspects, a cyclic shift configuration can identify the cyclic shift used for multiple PDCCH decoded bits, as follows regarding... Figure 6 As stated above.

[0064] In some aspects, UE 120 may determine the cyclic shift configuration for each repetition of the non-interleaved CORESET. For example, UE 120 may determine a first cyclic shift configuration (e.g., a first cyclic shift index) for a first repetition of the non-interleaved CORESET, a second cyclic shift configuration (e.g., a second cyclic shift index) for a second repetition of the non-interleaved CORESET, and so on. The repetition of the non-interleaved CORESET may be inter-slot repetition (e.g., repetition occurring in multiple time slots) and / or intra-slot repetition (e.g., repetition occurring in a single time slot).

[0065] In some aspects, such as when base station 110 sends a cyclic shift configuration (e.g., via RRC signaling), UE 120 may determine the cyclic shift configuration at least in part based on one or more configurations sent by base station 110. In some aspects, UE 120 may determine the cyclic shift configuration in another manner.

[0066] For example, UE 120 may determine the cyclic shift configuration for a specific repetition of a non-interleaved CORESET based at least in part on a slot index associated with the repetition (e.g., for inter-slot repetition) and / or a start symbol index associated with the repetition (e.g., for intra-slot repetition). For example, UE 120 may determine a first cyclic shift configuration for a first repetition of a non-interleaved CORESET based at least in part on the slot index and / or start symbol index of a first repetition, a second cyclic shift configuration for a second repetition of a non-interleaved CORESET based at least in part on the slot index and / or start symbol index of a second repetition, and so on. In this case, base station 110 may also determine the corresponding cyclic shift configuration for a specific repetition of a non-interleaved CORESET in a similar manner.

[0067] As shown by reference numeral 420 in the accompanying drawings, base station 110 can transmit one or more PDCCH candidates in a non-interleaved CORESET. That is, base station 110 can transmit one or more PDCCHs for UE 120 on one or more PDCCH candidates. In some aspects, such as when a non-interleaved CORESET is repeated in multiple repetitions, base station 110 can transmit one or more PDCCH candidates in the multiple repetitions of the non-interleaved CORESET. Base station 110 can use cyclic shifting to transmit on one or more PDCCH candidates according to a cyclic shift configuration determined by base station 110.

[0068] As shown by reference numeral 425 in the accompanying figure, UE 120 can monitor one or more PDCCH candidates in a non-interleaved CORESET. In some aspects, such as when a non-interleaved CORESET is repeated in multiple repetitions, UE 120 can monitor one or more PDCCH candidates in multiple repetitions of the non-interleaved CORESET. UE 120 can monitor one or more PDCCH candidates according to a cyclic shift configuration determined by UE 120 (e.g., for a specific repetition of the non-interleaved CORESET). That is, UE 120 can use cyclic shifting to decode one or more PDCCH candidates from one or more PDCCH candidates (e.g., de-shifting and / or similar operations) according to a cyclic shift configuration determined by UE 120 (e.g., for a specific repetition of the non-interleaved CORESET).

[0069] In some aspects, the different repetitions of the demodulation reference signal (DMRS) of the non-interleaved core set can be time-domain bundled. For example, repetitions of the non-interleaved core set can be received across one or more aggregated time slots. The one or more repetitions of the DMRS of the non-interleaved core set can be time-domain bundled, allowing the UE 120 to perform joint channel estimation across aggregated time slots, rather than performing separate channel estimation for each time slot based on the DMRS(one or more) received in that time slot. This improves channel estimation performance while maintaining spatial diversity through the repetition of the non-interleaved core set (e.g., at least in part based on a cyclic shift configuration).

[0070] As mentioned above, Figure 4 This is provided as an example. Other examples may be related to... Figure 4 The examples described are different.

[0071] Figure 5 This is a diagram illustrating example 500 of a non-interleaved CORESET repeating cyclic shift according to various aspects of this disclosure.

[0072] like Figure 5 As shown, the non-interleaved CORESET 505 may include multiple REG bundles 510. A REG bundle 510 may include multiple REGs. For example, a REG bundle 510 may include 2 REGs, 3 REGs, 4 REGs, 6 REGs, etc. As mentioned above, REG bundles may occupy contiguous frequency domain resources (e.g., REG bundle 2 may include frequency domain resources adjacent to those of REG bundle 1 and REG bundle 3). REG bundles may include REGs that are contiguous in the frequency domain and / or time domain. A REG bundle may include several REGs, such as two REGs, three REGs, six REGs, etc.

[0073] In some aspects, the REG bundles 510 of the non-interleaved CORESET 505 can be cyclically shifted according to the common frequency domain cyclic shift of each repetition of the non-interleaved CORESET 505 (e.g., by base station 110). That is, the repetition of REG bundles for the non-interleaved CORESET 505 can be cyclically shifted the same number of REG bundles in the frequency domain (e.g., the same cyclic shift index). In some aspects, the repetition of REG bundles for the non-interleaved CORESET 505 can be cyclically shifted the same number of resource blocks in the frequency domain. That is, if the REG bundle of the non-interleaved CORESET 505 includes two resource blocks, the repetition of REG bundles for the non-interleaved CORESET 505 can be cyclically shifted in the frequency domain by a multiple of two resource blocks (e.g., two resource blocks (e.g., one REG bundle), four resource blocks (e.g., two REG bundles), six resource blocks (e.g., three REG bundles), and / or similar cases). In some aspects, the REG bundles of the non-interleaved CORESET 505 can include different numbers of resource blocks.

[0074] For example, the REG bundles 510 of the first repetition (e.g., repetition 1) of the non-interleaved CORESET 505 can be cyclically shifted according to a first cyclic shift (e.g., zero REG bundles in the frequency domain, as shown), the REG bundles 510 of the second repetition (e.g., repetition 2) of the non-interleaved CORESET 505 can be cyclically shifted according to a second cyclic shift (e.g., two REG bundles in the frequency domain, as shown), the REG bundles 510 of the third repetition (e.g., repetition 3) of the non-interleaved CORESET 505 can be cyclically shifted according to a third cyclic shift (e.g., four REG bundles in the frequency domain, as shown), the REG bundles 510 of the fourth repetition (e.g., repetition 4) of the non-interleaved CORESET 505 can be cyclically shifted according to a fourth cyclic shift (e.g., six REG bundles in the frequency domain, as shown), and so on. In some respects, the cyclic shift can be based at least in part on the total number of repetitions of the non-interleaved CORESET 505 (e.g., the number of REG bundles of the non-interleaved CORESET 505 cyclic shift can be based at least in part on the total number of repetitions of the non-interleaved CORESET 505).

[0075] In some aspects, the cyclic shift configuration transmitted by base station 110 can identify the repeated cyclic shifts of the non-interleaved CORESET 505. In some aspects, UE 120 can determine the repeated cyclic shifts (or repeated common cyclic shifts) for the non-interleaved CORESET 505 based at least in part on the repeated start symbol indices. For example, UE 120 can determine the first cyclic shift of the first repeat based at least in part on the first start symbol of the first repeat, the second cyclic shift of the second repeat based at least in part on the second start symbol of the second repeat, and so on.

[0076] As mentioned above, Figure 5 This is provided as an example. Other examples may be related to... Figure 5 The examples described are different.

[0077] Figure 6 This is a diagram illustrating an example of a repeated cyclic shift of a non-interleaved CORESET according to various aspects of this disclosure. In particular, Figure 6 An example of cyclic shifting of the decoder bits of a non-interleaved CORESET 605 can be shown.

[0078] like Figure 6 As shown, the non-interleaved CORESET 605 can include multiple REG bundles (e.g., 8 REG bundles, as shown). A REG bundle can include multiple REGs. For example, a REG bundle can include 2 REGs, 3 REGs, 4 REGs, 6 REGs, etc. As mentioned above, REG bundles may occupy contiguous frequency domain resources (e.g., REG bundle 2 may include frequency domain resources adjacent to those of REG bundle 1 and REG bundle 3).

[0079] As shown by reference numerals 610, 615, 620, and 625 in the accompanying drawings, each repetition of the non-interleaved CORESET 605 can be encoded with multiple decoded bits. These decoded bits may include Cyclic Redundancy Check (CRC) bits, Downlink Control Information (DCI) payload bits, Radio Network Temporary Identifier (RNTI) bits, etc. These bits can be encoded by the base station 110 (e.g., using a Polar encoder, through rate matching, etc.) into a repetition of the non-interleaved CORESET. These decoded bits can be referred to as PDCCH decoded bits. Figure 6 The blocks shown (e.g., reference numerals 610, 615, 620, and 625) can represent multi-byte group indices of PDCCH decoded bits (e.g., including multiple PDCCH decoded bits). Figure 6As shown, one or more multibyte groups can be mapped to CCE. In some aspects, different multibyte groups may correspond to different REG bundles in a non-interleaved CORESET 605. For example, as shown by reference numeral 610, multibyte groups 0 and 1 may correspond to REG bundle 1, as shown by reference numeral 615, multibyte groups 4 and 5 may correspond to REG bundle 1, and so on.

[0080] In some aspects, the PDCCH decoding bits of the non-interleaved CORESET 605 can be cyclically shifted according to each repetition of the cyclic shift of the non-interleaved CORESET 605 (e.g., by base station 110). That is, the repeated PDCCH decoding bits for the non-interleaved CORESET 605 can be cyclically shifted by the same number of bits (e.g., the same cyclic shift index). In some aspects, the repeated PDCCH decoding bits for the non-interleaved CORESET 605 can be cyclically shifted by the same number of multi-byte groups.

[0081] For example, the PDCCH decoding bit 610 of the first repetition (e.g., repetition 1) of the non-interleaved CORESET 605 can be cyclically shifted according to the first cyclic shift (e.g., zero multi-byte group, as shown), the PDCCH decoding bit 615 of the second repetition (e.g., repetition 2) of the non-interleaved CORESET 605 can be cyclically shifted according to the second cyclic shift (e.g., four multi-byte group, as shown), the PDCCH decoding bit 620 of the third repetition (e.g., repetition 3) of the non-interleaved CORESET 605 can be cyclically shifted according to the third cyclic shift (e.g., eight multi-byte group, as shown), the PDCCH decoding bit 620 of the fourth repetition (e.g., repetition 4) of the non-interleaved CORESET 605 can be cyclically shifted according to the fourth cyclic shift (e.g., twelve multi-byte group, as shown), and so on. In some aspects, the cyclic shift may be based at least in part on the total number of repetitions of the non-interleaved CORESET 605 (e.g., the number of multi-byte groups of cyclic shifts of the PDCCH decoder bits of the non-interleaved CORESET 605 may be based at least in part on the total number of repetitions of the non-interleaved CORESET 605). In some aspects, one or more bits of the PDCCH decoder bits may correspond to one or more resource blocks of the non-interleaved CORESET 605.

[0082] In some aspects, the cyclic shift configuration transmitted by base station 110 can identify the respective cyclic shifts for the repetition of non-interleaved CORESET 605. In some aspects, UE 120 can determine the respective cyclic shifts (or common cyclic shifts for the repetition) for the repetition of non-interleaved CORESET 605 based at least in part on the respective start symbol indices for the repetition. For example, UE 120 can determine the first cyclic shift for the first repetition based at least in part on the first start symbol of the first repetition, determine the second cyclic shift for the second repetition based at least in part on the second start symbol of the second repetition, and so on.

[0083] In some aspects, the PDCCH bits for each repetition of the non-interleaved CORESET 605 can be randomized. In some aspects, the cyclic shift configuration can identify the sub-block interleaving configuration (e.g., sub-block interleaving pattern) for the PDCCH decoding bits of the non-interleaved CORESET 605 repetition. The sub-block interleaving configuration can vary between different repetitions of the non-interleaved CORESET 605. For example, UE 120 can determine a first sub-block interleaving configuration for the PDCCH decoding bits for a first repetition of the non-interleaved CORESET 605, a second sub-block interleaving configuration for the PDCC decoding bits for a second repetition of the non-interleaved CORESET 605, and so on. The sub-block interleaving configuration for the repetition of the non-interleaved CORESET can be based at least in part on the start symbol index of the repetition, the total number of repetitions of the non-interleaved CORESET, the slot index of the repetition (e.g., the slot index of the slot in which the repetition occurs), and / or similar content.

[0084] In some aspects, the cyclic shift configuration can identify the bit interleaving configuration (e.g., bit interleaving pattern) for repeated PDCCH decoding bits in the non-interleaved CORESET 605. The bit interleaving configuration can vary between different repetitions of the non-interleaved CORESET 605. For example, UE 120 can determine the first bit interleaving configuration for PDCCH decoding bits in the first repetition of the non-interleaved CORESET 605, the second bit interleaving configuration for PDCC decoding bits in the second repetition of the non-interleaved CORESET 605, and so on. The bit interleaving configuration for repetitions of the non-interleaved CORESET can be based at least in part on the start symbol index of the repetition, the total number of repetitions of the non-interleaved CORESET, the slot index of the repetition (e.g., the slot index of the slot in which the repetition is located), and / or similar content.

[0085] In some aspects, the cyclic shift configuration transmitted by base station 110 may identify the various cyclic shifts for the repetition of non-interleaved CORESET 605 (e.g., identifying cyclic shifts for PDCCH decoding bits, sub-block interleaving configurations for PDCCH decoding bits, bit interleaving configurations for PDCC decoding bits, etc.). In some aspects, UE 120 may determine the various cyclic shifts (or common cyclic shifts) for the repetition of non-interleaved CORESET 605 based at least in part on the respective start symbol indices for the repetition. For example, UE 120 may determine the first cyclic shift for the first repetition based at least in part on the first start symbol of the first repetition, determine the second cyclic shift for the second repetition based at least in part on the second start symbol of the second repetition, and so on.

[0086] As mentioned above, Figure 6 This is provided as an example. Other examples may be related to... Figure 6 The examples described are different.

[0087] Figure 7 This is a diagram illustrating an example process 700 performed by, for example, a UE, according to various aspects of this disclosure. Example process 700 is an example in which a UE (e.g., UE 120, etc.) performs an operation associated with a repeated specific cyclic shift of a non-interleaved CORESET.

[0088] like Figure 7 As shown, in some aspects, process 700 may include determining a cyclic shift configuration for one or more repetitions of a non-interleaved CORESET (block 710). For example, as described above, the UE (e.g., using a receive processor 258, a transmit processor 264, a controller / processor 280, a memory 282, and / or similar devices) may determine a cyclic shift configuration for one or more repetitions of a non-interleaved CORESET.

[0089] like Figure 7 As further shown, in some aspects, process 700 may include monitoring one or more PDCCH candidates in one or more repetitions of a non-interleaved CORESET, at least in part based on determining a cyclic shift configuration for one or more repetitions (block 720). For example, as described above, the UE (e.g., using receive processor 258, transmit processor 264, controller / processor 280, memory 282, and / or similar devices) may monitor one or more PDCCH candidates in one or more repetitions of a non-interleaved CORESET, at least in part based on determining a cyclic shift configuration for one or more repetitions.

[0100] In the tenth aspect, the sub-block interleaving configuration for repeating one or more repetitions of a non-interleaved CORESET, alone or in combination with one or more of the first to ninth aspects, is based at least in part on at least one of the following: the starting symbol index of the repetition, the total number of repetitions of the non-interleaved CORESET, or the slot index of the repetition.

[0101] In the eleventh aspect, alone or in combination with one or more of the first to tenth aspects, the non-interleaved CORESET encoding has a plurality of PDCCH decode bits, and determining the cyclic shift configuration for one or more repetitions of the non-interleaved CORESET includes determining the bit interleaving configuration for the plurality of PDCCH decode bits for one or more repetitions.

[0102] In the twelfth aspect, the bit interleaving configuration for repeating in one or more repetitions of a non-interleaved CORESET, alone or in combination with one or more of the first to eleventh aspects, is based at least in part on at least one of the following: the starting symbol index of the repetition, the total number of repetitions of the non-interleaved CORESET, or the time slot index of the repetition.

[0103] although Figure 7 The example box for process 700 is shown, but in some respects, process 700 may contain... Figure 7 Compared to the boxes depicted, there may be additional boxes, fewer boxes, different boxes, or boxes arranged differently. Additionally or alternatively, two or more boxes of process 700 may be executed in parallel.

[0104] Figure 8 This is a diagram illustrating an example process 800 performed by a base station, for example, according to various aspects of this disclosure. Example process 800 is an example in which a base station (e.g., base station 110, etc.) performs an operation associated with a repeated specific cyclic shift of a non-interleaved CORESET.

[0105] like Figure 8As shown, in some aspects, process 800 may include determining a cyclic shift configuration for one or more repetitions of the non-interleaved CORESET (block 810). For example, as described above, the base station (e.g., using transmit processor 220, receive processor 238, controller / processor 240, memory 242, and / or similar devices) may determine a cyclic shift configuration for one or more repetitions of the non-interleaved CORESET.

[0106] like Figure 8 As further shown, in some aspects, process 800 may include transmitting one or more PDCCH candidates in one or more repetitions of a non-interleaved CORESET, at least in part, based on determining a cyclic shift configuration for one or more repetitions (block 820). For example, as described above, a base station (e.g., using transmit processor 220, receive processor 238, controller / processor 240, memory 242, and / or similar devices) may transmit one or more PDCCH candidates in one or more repetitions of a non-interleaved CORESET, at least in part, based on determining a cyclic shift configuration for one or more repetitions.

[0107] Process 800 may include additional aspects, such as any single aspect or any combination of aspects of one or more other processes described below and / or in conjunction with one or more other processes described elsewhere herein.

[0108] In the first aspect, the non-interleaved CORESET includes one or more REG bundles, and the cyclic shift configuration identifies the frequency domain cyclic shift for the one or more REG bundles.

[0109] In the second aspect, either alone or in combination with the first aspect, the cyclic shift configuration identifies the frequency domain cyclic shift based on the number of REG bundles.

[0110] In the third aspect, alone or in combination with one or more of the first and second aspects, a first cyclic shift configuration identifier for a first repeat of a non-interleaved CORESET identifies a first cyclic shift index, and a second cyclic shift configuration identifier for a second repeat of a non-interleaved CORESET identifies a second cyclic shift index.

[0111] In the fourth aspect, alone or in combination with one or more of the first to third aspects, process 800 includes transmitting one or more repeated cyclic shift configurations for non-interleaved CORESET via radio resource control signaling.

[0112] In the fifth aspect, alone or in combination with one or more of the first to fourth aspects, the repeating cyclic shift configuration in one or more repetitions of the non-interleaved CORESET is based at least in part on the repeating start symbol index.

[0113] In the sixth aspect, either alone or in combination with one or more of the first to fifth aspects, the cyclic shift configuration is based at least in part on the total number of repetitions of the non-interleaved CORESET.

[0114] In the seventh aspect, one or more demodulated reference signals of non-interleaved CORESET, either alone or in combination with one or more of the first to sixth aspects, are configured as time-domain bundles.

[0115] In the eighth aspect, alone or in combination with one or more of the first to seventh aspects, the non-interleaved CORESET encoding has multiple PDCCH decode bits, and the cyclic shift configuration identifier is used for the cyclic shift of the multiple PDCCH decode bits.

[0116] In the ninth aspect, alone or in combination with one or more of the first to eighth aspects, the non-interleaved CORESET encoding has multiple PDCCH decode bits, and determining the cyclic shift configuration for one or more repetitions of the non-interleaved CORESET includes determining the sub-block interleaving configuration for the multiple PDCCH decode bits for one or more repetitions.
