Abstract

A method, system, and device for wireless communication are described. A user equipment (UE) may monitor a set of downlink control channel candidates associated with each other, the set of downlink control channel candidates including a first downlink control channel candidate during a first transmission time interval (TTI) and a last downlink control channel candidate during a second TTI after the first TTI. The UE may receive at least one repetition of downlink control information (DCI) within one of the first downlink control channel candidate or the last downlink control channel candidate based on the monitoring, the DCI scheduling a transmission between a base station and the UE.

[0002] The following relates to wireless communications, including techniques for timing relationships for repetition of a Physical Downlink Control Channel (PDCCH). [Background technology]

[0003]

[0003] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasts, and the like. These systems may be capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems, such as Long Term Evolution (LTE), LTE Advanced (LTE-A), or LTE-A Pro systems, and fifth generation (5G) systems, sometimes referred to as New Radio (NR) systems. These systems may employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), or Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple-access communication system may include one or more base stations or one or more network access nodes, each simultaneously supporting communication for multiple communication devices, sometimes known as user equipment (UE).

[0004]

[0004] Some wireless systems may support repetition of various signals, such as control information or data. For example, a UE may be configured to monitor multiple repetitions of a physical downlink control channel (PDCCH) transmission, where the monitoring is performed in each PDCCH candidate. The repeated PDCCH transmission may include downlink control information (DCI) that may schedule a transmission in the UE. When scheduling a transmission in the UE, the UE's actions may depend not only on the payload (e.g., data) of the DCI, but also on the relative timing of when the DCI was received. However, when multiple PDCCH candidates may be monitored and multiple repetitions of a PDCCH transmission may be received, there may be ambiguity as to when a particular timing must be triggered. Summary of the Invention

[0005]

[0005] The described techniques relate to improved methods, systems, devices, and apparatuses that support techniques for timing relationships for repetitions of a physical downlink control channel (PDCCH). In general, the described techniques may provide a set of rules, configurations, and / or signaling for determining the relative timing of a transmission scheduled at a user equipment (UE) via multiple repetitions of control data (e.g., multiple repetitions of downlink control information (DCI)). In some aspects, the relative timing of a transmission scheduled via one or more repetitions of a DCI may be defined relative to a last PDCCH candidate of a set of PDCCH candidates from which one or more repetitions of the DCI may be received. For example, a UE may monitor a set of associated PDCCH candidates configured for repetitions of a DCI and may receive at least one repetition of the DCI within the set of PDCCH candidates, where the DCI schedules a transmission at the UE. In this example, a scheduling offset that defines the relative timing for a scheduled transmission may be based on the last PDCCH candidate of the set of associated PDCCH candidates.

[0006] A method for wireless communication in a UE is described. The method may include monitoring a set of multiple downlink control channel candidates associated with each other, the set of multiple downlink control channel candidates including at least a first downlink control channel candidate during a first transmission time interval (TTI) and including a last downlink control channel candidate during a second TTI following the first TTI, receiving from a base station at least one repetition of a DCI within one of the first downlink control channel candidate or the last downlink control channel candidate based on the monitoring, the DCI scheduling a transmission between the base station and the UE, applying a scheduling offset associated with the transmission based on a timing of the last downlink control channel candidate, and communicating with the base station via the transmission based on the scheduling offset.

The apparatus may include at least one processor, a memory (e.g., operatively, communicatively, functionally, electronically, or electrically, etc.) coupled to the at least one processor, and instructions stored in the memory. The instructions may be executable by the processor to cause the apparatus to: monitor a set of multiple downlink control channel candidates associated with each other; the set of multiple downlink control channel candidates includes at least a first downlink control channel candidate during a first TTI and includes a last downlink control channel candidate during a second TTI following the first TTI; receive from a base station, based on the monitoring, at least one repetition of a DCI within one of the first downlink control channel candidate or the last downlink control channel candidate; the DCI schedules a transmission between the base station and the UE; apply a scheduling offset associated with the transmission based on a timing of the last downlink control channel candidate; and communicate with the base station via the transmission based on the scheduling offset.

The apparatus may include means for monitoring a set of multiple downlink control channel candidates associated with each other, the set of multiple downlink control channel candidates including at least a first downlink control channel candidate during a first TTI and including a last downlink control channel candidate during a second TTI after the first TTI, means for receiving from a base station at least one repetition of a DCI within one of the first downlink control channel candidate or the last downlink control channel candidate based on the monitoring, the DCI schedules a transmission between the base station and the UE, means for applying a scheduling offset associated with the transmission based on a timing of the last downlink control channel candidate, and means for communicating with the base station via the transmission based on the scheduling offset.

[0009] A non-transitory computer-readable medium storing code for wireless communication in a UE is described. The code may include instructions executable by at least one processor to: monitor a set of multiple downlink control channel candidates associated with each other, the set of multiple downlink control channel candidates including at least a first downlink control channel candidate during a first TTI and including a last downlink control channel candidate during a second TTI following the first TTI; receive from a base station at least one repetition of a DCI within one of the first downlink control channel candidate or the last downlink control channel candidate based on the monitoring, the DCI schedules a transmission between the base station and the UE; apply a scheduling offset associated with the transmission based on a timing of the last downlink control channel candidate; and communicate with the base station via the transmission based on the scheduling offset.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0065]

[0081] Some wireless systems may support repetition of various signals, such as control information or data. For example, a UE may be configured to monitor multiple repetitions of a physical downlink control channel (PDCCH) transmission, where the monitoring occurs in each PDCCH candidate. The repeated PDCCH transmission may include downlink control information (DCI) that may schedule a transmission in the UE. When scheduling a transmission in the UE, the UE's behavior may depend not only on the payload (e.g., data) of the DCI, but also on the relative timing of when the DCI was received. For example, if the DCI schedules the UE to transmit a sounding reference signal (SRS), the timing of the SRS may be based on the time the DCI was received. However, when multiple PDCCH candidates may be monitored and when multiple repetitions of the PDCCH (e.g., multiple repetitions of the DCI) may be received, there may be ambiguity as to when a particular timing must be triggered.

[0066]

[0082] Thus, the techniques described herein may provide a set of rules, configurations, and / or signaling for determining the relative timing of a transmission scheduled at a UE via multiple repetitions of control data (e.g., via multiple repetitions of a DCI). In some aspects, the relative timing of a transmission scheduled via one or more repetitions of a DCI may be defined with respect to a last PDCCH candidate of a set of PDCCH candidates in which one or more repetitions of the DCI may be received. For example, the UE may monitor a set of associated PDCCH candidates configured for a repetition of the DCI and may receive at least one repetition of the DCI within the set of PDCCH candidates, where the DCI schedules a transmission at the UE. In this example, a scheduling offset that defines the relative timing for a scheduled transmission may be based on the last PDCCH candidate of the set of associated PDCCH candidates.

[0067]

[0083] In some implementations, the scheduling offset for a transmission scheduled by a DCI repetition may depend on the type of transmission scheduled by the DCI repetition (e.g., a channel state information (CSI) report, a CSI reference signal (CSI-RS), a physical downlink shared channel (PDSCH) transmission, a physical uplink shared channel (PUSCH) transmission, an SRS). Depending on the type of scheduled transmission, the scheduling offset may define the amount of symbols between the last symbol of the last PDCCH candidate and the first symbol of the scheduled transmission, the amount of slots between the last PDCCH candidate and the first slot in which the scheduled transmission may be transmitted or received, or both. The UE may be preconfigured with various rules for determining the scheduling offset for a transmission scheduled by a DCI repetition. Additionally or alternatively, the rules for determining the scheduling offset may be signaled by the network to the UE (e.g., via radio resource control (RRC) signaling).

[0068]

[0084] Aspects of the present disclosure are first described in the context of a wireless communication system. Additional aspects of the present disclosure are described in the context of example resource allocation schemes and example process flows. Aspects of the present disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flow charts relating to techniques for timing relationships for repetitions of PDCCH.

[0069]

[0085] 1 illustrates an example of a wireless communication system 100 supporting techniques for timing relationships for repetition of a PDCCH according to aspects of the disclosure. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, a LTE-Advanced (LTE-A) network, a LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission-critical) communications, low latency communications, communications with low-cost and low-complexity devices, or any combination thereof.

[0070]

[0086] The base stations 105 may be distributed throughout a geographic area to form a wireless communication system 100 and may be devices of different forms or with different capabilities. The base stations 105 and the UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which the UEs 115 and the base station 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which the base stations 105 and the UEs 115 may support communication of signals according to one or more radio access technologies.

[0071]

[0087] The UEs 115 may be distributed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be fixed, or mobile, or both at different times. The UEs 115 may be devices of different forms or with different capabilities. Some example UEs 115 are shown in FIG. 1. The UEs 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, base stations 105, or network equipment (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network equipment), as shown in FIG. 1.

[0072]

[0088] The base stations 105 may communicate with the core network 130, with each other, or both. For example, the base stations 105 may interface with the core network 130 through one or more backhaul links 120 (e.g., via an S1, N2, N3, or other interface). The base stations 105 may communicate with each other over the backhaul links 120 (e.g., via an X2, Xn, or other interface), either directly (e.g., directly between the base stations 105) or indirectly (e.g., via the core network 130), or both. In some examples, the backhaul links 120 may be or include one or more wireless links.

[0073]

[0089] One or more of the base stations 105 described herein may include or be referred to by one skilled in the art as a base transceiver station, radio base station, access point, radio transceiver, Node B, eNode B (eNB), Next Generation Node B or Giga Node B (any of which may be referred to as a gNB), Home Node B, Home eNode B, or other suitable terminology.

[0074]

[0090] The UE 115 may include or be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where a "device" may also be referred to as a unit, a station, a terminal, or a client, among other examples. The UE 115 may also be a cellular phone, a personal digital assistant (PDA), a multimedia / entertainment device (e.g., a radio, an MP3 player, or a video device), a camera, a game console, a navigation / positioning device (e.g., a GNSS (Global Navigation Satellite System) device, e.g., based on GPS (Global Positioning System), Beidou, GLONASS, or Galileo, or a ground-based device), a tablet computer, a laptop computer, a personal computer, a netbook, a smartbook, a personal computer, a smart device, a wearable device (e.g., a smart watch, a smart clothing item, a smart The UE 115 may include or may be referred to as a personal electronic device such as a smart glass, a virtual reality goggle, a smart wristband, smart jewelry (e.g., a smart ring, a smart bracelet), a drone, a robot / robotic device, a vehicle, a vehicular device, a meter (e.g., a parking meter, an electric meter, a gas meter, a water meter), a monitor, a gas pump, an appliance (e.g., a kitchen appliance, a washer, a dryer), a location tag, a medical / healthcare device, an implant, a sensor / actuator, a display, or any other suitable device configured to communicate over a wireless or wired medium. In some examples, the UE 115 may include or may be referred to as a Wireless Local Loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a Machine Type Communication (MTC) device, among other examples, which may be implemented in various objects such as an appliance, a vehicle, or a meter, among other examples.

[0075]

[0091] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technologies that allow devices to communicate with each other or with the base station 105 without human intervention. In some examples, M2M communication or MTC may include communication from devices that incorporate sensors or meters to measure or capture information and relay that information to a central server or application program that can utilize the information or present the information to a human interacting with the program or application. Some UEs 115 may be designed to collect information or enable automated behavior of machines. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business billing. In an aspect, the techniques disclosed herein may be applicable to MTC or IoT UEs. MTC or IoT UE may include MTC / Enhanced MTC (eMTC also called CAT-M, Cat M1) UE, NB-IoT (also called CAT NB1) UE, as well as other types of UE. eMTC and NB-IoT may refer to future technologies that may evolve from or be based on these technologies. For example, eMTC may include FeMTC (further eMTC), eFeMTC (further enhanced eMTC), and mMTC (massive MTC), and NB-IoT may include eNB-IoT (enhanced NB-IoT) and FeNB-IoT (further enhanced NB-IoT).

[0076]

[0092] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasts, and the like. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). A wireless network, e.g., a wireless local area network (WLAN), such as a Wi-Fi (e.g., Institute of Electrical and Electronics Engineers (IEEE) 802.11) network, may include an access point (AP) that may communicate with one or more wireless or mobile devices. The AP may be coupled to a network, such as the Internet, and may enable the mobile device to communicate over the network (or to communicate with other devices coupled to the access point). A wireless device may communicate bidirectionally with network devices. For example, in a WLAN, a device may communicate with an associated AP via a downlink (e.g., a communication link from the AP to the device) and an uplink (e.g., a communication link from the device to the AP). A wireless personal area network (PAN), which may include a Bluetooth connection, may provide short-range wireless connectivity between two or more paired wireless devices. For example, a wireless device such as a cellular phone may utilize wireless PAN communications to exchange information, such as audio signals, with a wireless headset. Components within a wireless communication system may be coupled (e.g., operatively, communicatively, functionally, electronically, and / or electrically) with one another.

[0077]

[0093] The UEs 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, which may at times act as relays, as shown in FIG. 1, as well as base stations 105 and network equipment, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples.

[0078]

[0094] The UE 115 and the base station 105 may wirelessly communicate with each other via one or more communication links 125 via one or more carriers. The term “carrier” may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication links 125. For example, a carrier used for the communication links 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth part (BWP)) operated according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry collection signaling (e.g., synchronization signals, system information), control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. The UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0079]

[0095] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition or control signaling that coordinates the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be arranged according to a channel raster for discovery by the UE 115. A carrier may operate in a standalone mode, where initial acquisition and connection may be made by the UE 115 over the carrier, or a carrier may operate in a non-standalone mode, where a connection is anchored using a different carrier (e.g., of the same or different radio access technology).

[0080]

[0096] The communication links 125 shown in the wireless communication system 100 may include uplink transmissions from the UE 115 to the base station 105 or downlink transmissions from the base station 105 to the UE 115. A carrier may carry downlink or uplink communications (e.g., in FDD mode) or may be configured to carry downlink and uplink communications (e.g., in TDD mode).

[0081]

[0097] A carrier may be associated with a particular bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth may be one of several predefined bandwidths (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)) for a carrier of a particular radio access technology. The devices (e.g., the base station 105, the UE 115, or both) of the wireless communication system 100 may have a hardware configuration that supports communication on a particular carrier bandwidth or may be configurable to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., a sub-band, BWP) or all of the carrier bandwidth.

[0082]

[0098] A signal waveform transmitted on a carrier may be composed of multiple subcarriers (e.g., using a multi-carrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM). In a system employing MCM techniques, a resource element may consist of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and the subcarrier spacing (SCS) have an inverse relationship. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Thus, the more resource elements and the higher the order of the modulation scheme that the UE 115 receives, the higher the data rate of the UE 115 may be. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), where the use of multiple spatial layers may further increase data rates or data integrity for communications with UE 115.

[0083]

[0099] One or more numerologies for a carrier may be supported, where the numerology may include the SCS(Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs having the same or different numerologies. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time, and communication for the UE 115 may be limited to one or more active BWPs.

[0084]

[0100] The time interval for the base station 105 or the UE 115 may be, for example, T s =1 / (Δf max N f) seconds, where Δf max may represent the maximum SCS supported, and N f may represent the maximum discrete Fourier transform (DFT) size supported. The communication resource time intervals may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0085]

[0101] Each frame may include multiple consecutively numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into several slots. Alternatively, each frame may include a variable number of slots, and the number of slots may depend on the SCS. Each slot may include several symbol periods (e.g., depending on the length of a cyclic prefix prepended to each symbol period). In some wireless communications systems 100, a slot may be further divided into multiple minislots containing one or more symbols. Excluding the cyclic prefix, each symbol period may include one or more (e.g., N f The duration of a symbol period may depend on the SCS or frequency band of operation.

[0086]

[0102] A subframe, slot, minislot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communications system 100 may be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0087]

[0103] The physical channels may be multiplexed on the carriers according to various techniques. The physical control channels and the physical data channels may be multiplexed on the downlink carriers using, for example, one or more of a time division multiplexing (TDM), a frequency division multiplexing (FDM), or a hybrid TDM-FDM technique. A control region (e.g., a control resource set (CORESET)) for the physical control channel may be defined by a number of symbol periods and may span across the system bandwidth of the carrier or a subset of the system bandwidth. One or more control regions (e.g., a CORESET) may be configured for a set of UEs 115. For example, one or more of the UEs 115 may monitor or search the control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels configured in a cascaded manner. The aggregation level for the control channel candidates may refer to a number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for sending control information to multiple UEs 115 and a UE-specific search space set for sending control information to a particular UE 115.

[0088]

[0104] Each base station 105 may provide communication coverage via one or more cells, e.g., macro cells, small cells, hot spots, or other types of cells, or any combination thereof. The term "cell" may refer to a logical communication entity used for communication with the base station 105 (e.g., on a carrier) and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other) to distinguish neighboring cells. In some examples, a cell may also refer to a geographic coverage area 110 or a portion (e.g., a sector) of a geographic coverage area 110 in which the logical communication entity operates. Such a cell may range from a smaller area (e.g., a structure, a subset of a structure) to a larger area depending on various factors such as the capabilities of the base station 105. For example, a cell may be or include a building, a subset of a building, or an exterior space between or overlapping with the geographic coverage area 110, among other examples.

[0089]

[0105] A macro cell generally covers a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UEs 115 subscribing to the service of a network provider supporting the macro cell. A small cell may be associated with a lower power base station 105 compared to a macro cell, and the small cell may operate in the same or different (e.g., licensed, unlicensed) frequency band as the macro cell. A small cell may provide unrestricted access to UEs 115 subscribing to the service of a network provider, or may provide restricted access to UEs 115 having an association with a small cell (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with a user at home or in the office). A base station 105 may support one or more cells and may also support communication on one or more cells using one or more component carriers.

[0090]

[0106] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access to different types of devices.

[0091]

[0107] In some examples, the base stations 105 are mobile and may therefore provide communication coverage to moving geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. The wireless communication system 100 may include heterogeneous networks in which different types of base stations 105 provide coverage to various geographic coverage areas 110, e.g., using the same or different radio access technologies.

[0092]

[0108] The wireless communication system 100 may be configured to support ultra-reliable or low latency communications, or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low latency communications (URLLC) or mission-critical communications. The UE 115 may be designed to support ultra-reliable, low latency, or critical functions (e.g., mission-critical functions). Ultra-reliable communications may include private or group communications and may be supported by one or more mission-critical services, such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions may include service prioritization, and the mission-critical services may be used for public safety or general commercial applications. The terms ultra-reliable, low latency, mission-critical, and ultra-reliable low latency may be used interchangeably herein.

[0093]

[0109] In some examples, the UE 115 may also be able to communicate directly with other UEs 115 over a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communication may be within the geographic coverage area 110 of the base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105 or otherwise unable to receive transmissions from the base station 105. In some examples, a group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system in which each UE 115 transmits to every other UE 115 in the group. In some examples, the base station 105 facilitates scheduling of resources for D2D communication. In other cases, D2D communication occurs between UEs 115 without the involvement of the base station 105.

[0094]

[0110] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) that manages access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) that routes packets or interconnection to external networks. The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management, for the UEs 115 served by the base stations 105 associated with the core network 130. User IP packets may be forwarded through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entities may be connected to IP services 150 for one or more network operators. The IP services 150 may include access to the Internet, an intranet(s), an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0095]

[0111] Some of the network devices, such as the base station 105, may include subcomponents, such as an access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with the UE 115 through one or more other access network transmitting entities 145, which may be referred to as a radio head, a smart radio head, or a transmit / receive point (TRP). Each access network transmitting entity 145 may include one or more antenna panels. In some configurations, various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or integrated into a single network device (e.g., the base station 105).

[0096]

[0112] The wireless communication system 100 may operate using one or more frequency bands, typically ranging from 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the 300 MHz to 3 GHz region is known as the ultra-high frequency (UHF) region or decimeter band, because the wavelengths range in length from approximately 1 decimeter to 1 meter. Although UHF waves may be blocked or redirected by buildings and environmental features, these waves may penetrate structures sufficiently for a macrocell to serve UEs 115 located indoors. Transmission of UHF waves may be associated with smaller antennas and shorter distances (e.g., less than 100 kilometers) compared to transmissions using smaller frequencies and longer waves in the short wave (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0097]

[0113] The wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may employ Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band, such as the 5 GHz Industrial, Scientific, and Medical (ISM) band. When operating in an unlicensed radio frequency spectrum band, devices such as the base station 105 and the UE 115 may employ carrier sensing for collision detection and avoidance. In some examples, operation in an unlicensed band may be based on a carrier aggregation configuration with a component carrier operating in a licensed band (e.g., LAA). Operation in an unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.

[0098]

[0114] The base station 105 or UE 115 may be equipped with multiple antennas that may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the base station 105 or UE 115 may be located in one or more antenna arrays or antenna panels that may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located in an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with the base station 105 may be located in various geographic locations. The base station 105 may have an antenna array with several rows and columns of antenna ports that the base station 105 may use to support beamforming of communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panels may support radio frequency beamforming for signals transmitted through the antenna ports.

[0099]

[0115] A base station 105 or a UE 115 may use MIMO communications to exploit multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may be transmitted by a transmitting device, for example, via different antennas or different combinations of antennas. Similarly, the multiple signals may be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports used for channel measurements and reporting. MIMO techniques include single-user MIMO (SU-MIMO), in which multiple spatial layers are transmitted to the same receiving device, and multi-user MIMO (MU-MIMO), in which multiple spatial layers are transmitted to multiple devices.

[0100]

[0116] Beamforming, sometimes referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used in a transmitting or receiving device (e.g., base station 105, UE 115) to shape or steer an antenna beam (e.g., transmit beam, receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals communicated through antenna elements of an antenna array such that some signals propagating in a particular orientation relative to the antenna array experience constructive interference and others experience destructive interference. Adjustment of signals communicated through antenna elements may include a transmitting or receiving device applying an amplitude offset, a phase offset, or both to signals conveyed through an antenna element associated with the device. The adjustment associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., relative to the antenna array of the transmitting or receiving device, or to some other orientation).

[0101]

[0117] The base station 105 or the UE 115 may use beam sweeping techniques as part of a beamforming operation. For example, the base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform a beamforming operation for directional communication with the UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times in different directions by the base station 105. For example, the base station 105 may transmit signals according to different beamforming weight sets associated with different transmission directions. The transmissions in different beam directions may be used to identify (e.g., by a transmitting device such as the base station 105 or by a receiving device such as the UE 115) beam directions for subsequent transmission or reception by the base station 105.

[0102]

[0118] Some signals, such as data signals associated with a particular receiving device, may be transmitted by the base station 105 in a single beam direction (e.g., a direction associated with a receiving device, such as the UE 115). In some examples, a beam direction associated with a transmission along a single beam direction may be determined based on signals transmitted in one or more beam directions. For example, the UE 115 may receive one or more of the signals transmitted by the base station 105 in different directions and report to the base station 105 an indication of the signal received by the UE 115 with the best signal quality or an otherwise acceptable signal quality.

[0103]

[0119] In some examples, transmission by a device (e.g., by the base station 105 or the UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a composite beam for transmission (e.g., from the base station 105 to the UE 115). The UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured number of beams across the system bandwidth or one or more subbands. The base station 105 may transmit a reference signal (e.g., cell-specific reference signal (CRS), channel state information reference signal (CSI-RS)), which may be precoded or amplicoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel type codebook, linear combination type codebook, port selection type codebook). Although these techniques have been described with respect to signals transmitted in one or more directions by the base station 105, the UE 115 may employ similar techniques for transmitting a signal multiple times in different directions (e.g., to identify a beam direction for subsequent transmission or reception by the UE 115) or for transmitting a signal in a single direction (e.g., to transmit data to a receiving device).

[0104]

[0120] A receiving device (e.g., UE 115) may attempt multiple receiving configurations (e.g., directional listening) when receiving various signals, such as synchronization signals, reference signals, beam selection signals, or other control signals, from the base station 105. For example, the receiving device may attempt multiple receiving directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of the antenna array, or by processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of the antenna array, any of which may be referred to as "listening" according to different receiving configurations or receiving directions. In some examples, the receiving device may use a single receiving configuration to receive along a single beam direction (e.g., when receiving a data signal). A single receive configuration may be aligned in a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening according to multiple beam directions).

[0105]

[0121] The wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communication at the bearer or Packet Data Convergence Protocol (PDCP) layer may be IP-based. A Radio Link Control (RLC) layer may perform packet segmentation and reassembly to communicate on logical channels. A Medium Access Control (MAC) layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer may also use error detection, error correction, or both techniques to support retransmissions at the MAC layer to improve link efficiency. In the control plane, a Radio Resource Control (RRC) protocol layer may establish, configure, and maintain an RRC connection between the UE 115 and the base station 105 or core network 130, which supports radio bearers for user plane data. In the physical layer, transport channels may be mapped to physical channels.

[0106]

[0122] The UE 115 and the base station 105 may support retransmission of data to increase the likelihood that the data is successfully received. Hybrid Automatic Repeat Request (HARQ) feedback is one technique for increasing the likelihood that the data is accurately received on the communication link 125. HARQ may include a combination of error detection (e.g., using a Cyclic Redundancy Check (CRC)), forward error correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). HARQ may improve throughput at the MAC layer in poor radio conditions (e.g., low signal-to-noise conditions). In some examples, a device may support same-slot HARQ feedback, where the device may provide HARQ feedback in a particular slot for data received in a previous symbol in that slot. In other cases, the device may provide HARQ feedback in a subsequent slot or according to some other time interval.

[0107]

[0123] In some aspects, a UE 115 of a wireless communication system 100 may be configured with up to three CORESETs in a given BWP. A CORESET may include one or more activated transmission configuration indication (TCI) states for PDCCH repetitions and may be associated with an amount of resource blocks (RBs) in the frequency domain and an amount of symbols or other TTIs (e.g., an amount of OFDM symbols) in the time domain. Resources for a CORESET may be configured via RRC signaling. In some aspects, a CORESET configured in a UE 115 may be associated with a CCE resource element group (CCE-REG) mapping type (e.g., CCE-REG bundle mapping type), a granularity of precoding, an identifier related to scrambling for a PDCCH demodulation reference signal (DMRS) (e.g., a scrambling identifier), coded bits of DCI content, or any combination thereof.

[0108]

[0124] In some aspects, the UE 115 may be configured with up to 10 search space sets within a given BWP of a component carrier. In some aspects, each search space set may be associated with one CORESET and may include a set of monitoring opportunities. In some aspects, a search space set may include a set of control channel monitoring opportunities (e.g., PDCCH monitoring opportunities). Furthermore, the UE 115 may be configured to determine the control channel monitoring opportunities associated with a given search space set based on one or more characteristics of the search space set that may be configured (e.g., pre-configured) in the UE 115, indicated to the UE 115 via the base station 105 (e.g., via RRC), or both. The UE 115 may be configured with one or more different types of search space sets (e.g., searchSpaceType), including UE-specific search space sets, common search space sets, or both. Furthermore, each search space set may be associated with one or more DCI formats to be monitored.

[0109]

[0125] In some aspects, various parameters of the search space set configuration may be configured (e.g., via RRC signaling), including, but not limited to, the CORESET associated with each search space set, the periodicity and offset of monitoring opportunities, monitoring symbols within a slot (e.g., time domain monitoring), the DCI format to be monitored by the UE 115, the amount of PDCCH candidates for a given aggregation level, the PDCCH candidates associated with each search space set, the aggregation level for each PDCCH candidate, the candidate index, etc.

[0110]

[0126] The parameters of the search space set are the monitoring opportunities (e.g., k s slots) in a period (k s ), slot (for example, o s The offset for the monitoring opportunity in units of slots (o s ) (e.g., monitoringSlotPeriodicityAndOffset), a duration (T s ) (where T s <k s ), or any combination thereof.

[0112] and frame

[0113]

[0114] In some aspects, when monitoring the control channel, the UE 115 may determine the amount of PDCCH monitoring opportunities in a slot.

[0115]

number

[0116] Starting from T s may be configured to monitor control channel candidates (e.g., PDCCH candidates) over a search space set s for the next k consecutive slots s -T s The UE 115 may refrain from monitoring the control channel candidates for the search space set s for consecutive slots. The amount of control channel candidates (e.g., PDCCH candidates) may be based on an aggregation level of wireless communications at the UE 115 (e.g., an amount of CCEs).

[0117]

[0127] In some aspects, the UE 115 may be configured to monitor the control channel according to a control channel monitoring pattern (e.g., a PDCCH monitoring pattern) within a slot (e.g., monitoringSymbolsWithinSlot). For example, the PDCCH monitoring pattern within a slot may indicate a first symbol of a CORESET within the slot for PDCCH monitoring. For example, in the context of a slot including 14 symbols, the CORESET configured in the UE 115 may be associated with a search space set including three symbols, and the control channel monitoring pattern (e.g., monitoringSymbolsWithinSlot) associated with the search space set may be configured as "01000010001000". In this example, the UE 115 may be configured to determine that there are three monitoring opportunities within each slot in which the search space set exists. Furthermore, the UE 115 may be configured to determine that the three monitoring opportunities begin at the second symbol, the seventh symbol, and the eleventh symbol of the respective slot in which the search space exists.

[0118]

[0128] In the context of SFN, an SFN PDCCH transmission (e.g., PDCCH DMRS) may be associated with two TCI states. In particular, for an SFN PDCCH transmission, one CORESET may be activated in the UE 115 with two active TCI states. In such a case, each control channel candidate (e.g., PDCCH candidate) of a search space set associated with a CORESET may be associated with two active TCI states of the CORESET.

[0119]

[0129] Similarly, for PDCCH repetitions where each PDCCH repetition includes a PDCCH candidate, two PDCCH candidates (e.g., two PDCCH repetitions) may be linked (e.g., associated) together for the same possible control channel transmission repetition (e.g., DCI repetition). In the context of PDCCH repetitions, the payloads (e.g., DCI payloads) of the two PDCCH candidates (e.g., two PDCCH repetitions) may be the same. For example, a first PDCCH candidate may be associated or linked to a second PDCCH candidate. In this example, a first repetition of DCI may be transmitted in the first PDCCH candidate and a second repetition of DCI may be transmitted in the second PDCCH candidate, where the first repetition and the second repetition of DCI are the same. In this example, the UE 115 may receive and / or decode only the first repetition of DCI or only the second repetition of DCI. Additionally or alternatively, the UE 115 may receive and / or decode both the first and second repetitions of the DCI by performing a soft-combining of the first and second repetitions of the DCI. From the network's (e.g., base station 105) perspective, the network cannot know whether the UE 115 is going to decode the first PDCCH repetition (first PDCCH candidate), the second PDCCH repetition (second PDCCH candidate), or both (via soft-combining).

[0120]

[0130] In this regard, the UE 115 may monitor PDCCH candidates for blind decoding within a search space set to receive one or more repetitions of a control channel transmission (e.g., DCI), where at least one control channel transmission (e.g., at least one PDCCH candidate) may pass a cyclic redundancy check (CRC) for successful decoding. In some aspects, associated / linked PDCCH candidates may have the same aggregation level (e.g., the same amount of CCE).

[0121]

[0131] In some aspects, related PDCCH candidates in different search space sets associated with a corresponding CORESET may be linked together (e.g., associated) for PDCCH repetitions. In some cases, two PDCCH candidates with the same candidate index across two related search space sets may be linked or associated. In other cases, PDCCH candidates with the same starting CCE index may be linked. In some aspects, the set of related / linked PDCCH candidates may be configured via control signaling (e.g., RRC signaling). For example, the UE 115 may receive an RRC message indicating that a first PDCCH candidate in a first search space set is linked (e.g., associated) to a second PDCCH candidate in a second search space set. Furthermore, the UE 115 may be configured with a set of linked / related PDCCH candidates that are in the same slot or TTI (e.g., intra-slot PDCCH repetitions), a set of linked / related PDCCH candidates that are in different slots (e.g., intra-slot PDCCH repetitions), or both.

[0122]

[0132] As previously noted herein, when scheduling transmissions at the UE 115 via a DCI, the behavior of the UE 115 may depend not only on the payload (e.g., data) of the DCI but also on the relative timing of when the DCI was received. Thus, when multiple PDCCH candidates may be monitored and when multiple repetitions of a PDCCH (e.g., multiple repetitions of a DCI) may be received, there may be ambiguity as to when a particular timing must be triggered.

[0123]

[0133] Thus, the wireless communications system 100 may support techniques that provide a set of rules, configurations, and / or signaling for determining the relative timing of a transmission scheduled at a UE 115 via multiple repetitions of control data (e.g., via multiple repetitions of DCI). In some aspects, the relative timing of a transmission scheduled via one or more repetitions of DCI may be defined with respect to the last PDCCH candidate of a set of PDCCH candidates on which one or more repetitions of DCI may be received.

[0124]

[0134] For example, the UE 115 of the wireless communication system 100 may monitor a set of associated PDCCH candidates configured for a repetition of the DCI and may receive at least one repetition of the DCI in the set of PDCCH candidates from the base station 105, where the DCI schedules a transmission at the UE 115. In this example, a scheduling offset defining a relative timing for a scheduled transmission may be based on the last PDCCH candidate of the set of associated PDCCH candidates. The UE 115 may then apply the determined scheduling offset to perform wireless communication with the base station 105. In particular, the UE 115 may apply the determined scheduling offset when performing a transmission (e.g., uplink transmission, downlink transmission) scheduled by one or more repetitions of the DCI.

[0125]

[0135] In some implementations, the scheduling offset for a transmission scheduled by a DCI repetition may depend on the type of transmission scheduled by the DCI repetition (e.g., CSI reporting, CSI-RS, PDSCH transmission, PUSCH transmission, SRS). Depending on the type of scheduled transmission, the scheduling offset may define the amount of symbols between the last symbol of the last PDCCH candidate and the first symbol of the scheduled transmission, the amount of slots between the last PDCCH candidate and the first slot in which the scheduled transmission may be transmitted or received, or both. In some implementations, the UE 115 of the wireless communication system 100 may be pre-configured with various rules for determining the scheduling offset for a transmission scheduled by a DCI repetition. Additionally or alternatively, the rules for determining the scheduling offset may be signaled by the network to the UE 115 (e.g., via RRC signaling from the base station 105).

[0126]

[0136] The techniques described herein may provide improved scheduling of wireless communications. In particular, by defining signaling, rules, and / or configurations that enable the UE 115 and base station 105 to determine the timing of scheduled transmissions via PDCCH repetition, the techniques described herein may enable the UE 115 and base station 105 to efficiently determine the timing of scheduled transmissions. Furthermore, by enabling wireless devices to more efficiently determine the timing of scheduled transmissions via PDCCH repetition, the techniques described herein may enable more widespread use of communications using PDCCH repetition within the wireless communications system 100, thereby improving reliability of wireless communications, improving transmit diversity, and further protecting wireless communications against interference.

[0127]

[0137] 2 illustrates an example of a wireless communications system 200 that supports techniques for timing relationships for repetitions of a PDCCH in accordance with aspects of the disclosure. In some examples, the wireless communications system 200 may implement or be implemented by aspects of the wireless communications system 100. For example, the wireless communications system 200 may support signaling and techniques for determining the timing of transmissions that are scheduled via one or more repetitions of a PDCCH transmission.

[0128]

[0138] The wireless communication system 200 may include a base station 105-a and a UE 115-a, which may be an example of the base station 105 and the UE 115 described with reference to FIG. 1. The UE 115-a may communicate with the base station 105-a using a communication link 205, which may be an example of an NR or LTE link between the UE 115-a and the base station 105-a. In some cases, the communication link 205 between the UE 115-a and the base station 105-a may include an example of an access link (e.g., a Uu link), which may include a bidirectional link enabling both uplink and downlink communications. For example, the UE 115-a may transmit uplink signals, such as uplink control signals or uplink data signals, to the base station 105-a using the communication link 205, and the base station 105-a may transmit downlink signals, such as downlink control signals or downlink data signals, to the UE 115-a using the communication link 205.

[0129]

[0139] In some aspects, the wireless communications system 200 may support techniques that provide a set of rules, configurations, and / or signaling for determining the relative timing of a transmission scheduled at the UE 115-a via multiple repetitions of control data (e.g., via multiple repetitions of DCI). In some aspects, the relative timing of a transmission scheduled via one or more repetitions of DCI may be defined with respect to a last PDCCH candidate of a set of PDCCH candidates for which one or more repetitions of DCI may be received. In this disclosure, the term “last PDCCH candidate” may refer to a PDCCH candidate from a set of PDCCH candidates that starts latest in time, ends latest in time, or both. By providing a set of signaling and rules for determining the timing of a transmission scheduled via multiple repetitions of PDCCH transmissions, the techniques described herein may enable improved scheduling of wireless communications at the UE 115-a and enable more widespread use of PDCCH repetitions.

[0130]

[0140] For example, the UE 115-a may monitor a set of PDCCH candidates 210 associated with each other. For example, as shown in FIG. 2, the UE 115-a may monitor a first PDCCH candidate 210-a and a last PDCCH candidate 210-b, where the first PDCCH candidate 210-a and the last PDCCH candidate 210-b are associated (e.g., linked, associated) with each other for a PDCCH repetition. In some aspects, the first PDCCH candidate 210-a may be disposed within a first TTI 225-a (e.g., a first slot) and the last PDCCH candidate 210-b may be disposed within a second TTI 225-b (e.g., a second slot) that is subsequent to (e.g., after) the first TTI 225-a.

[0131]

[0141] In some aspects, the UE 115-a may receive at least one repetition of a downlink control channel transmission (e.g., DCI) from the base station 105-a based on the monitoring. In particular, the UE 115-a may receive at least one repetition of the DCI in the first PDCCH candidate 210-a, the last PDCCH candidate 210-b, or both. In some aspects, the at least one repetition of the DCI may schedule a transmission 215 (e.g., uplink transmission 215-b, downlink transmission 215-a) between the UE 115-a and the base station 105-a. The transmission 215 scheduled via the one or more repetitions of the DCI may include, but is not limited to, a CSI-RS, a CSI report, a PDSCH transmission, a PUSCH transmission, an SRS, etc.

[0132]

[0142] In some aspects, the UE 115-a and the base station 105-a may be configured to determine and / or apply a scheduling offset associated with the transmission 215 to determine the relative timing of the scheduled transmission 215. In some aspects, the relative timing of the transmission 215 scheduled via one or more repetitions of the DCI may be defined with respect to a last PDCCH candidate 210-b of a set of PDCCH candidates 210 from which one or more repetitions of the DCI may be received. For example, as shown in FIG. 2, the UE 115-a and the base station 105-a may be configured to determine / apply a scheduling offset 220-a of the transmission 215 with respect to the last symbol of the last PDCCH candidate 210-b. In an additional or alternative implementation, the UE 115-a and the base station 105-a may be configured to determine / apply a scheduling offset 220-b for the transmission 215, where the scheduling offset 220-b defines the amount of TTI 225 (e.g., the amount of slots) separating the TTI 225 of the last PDCCH candidate 210-b (e.g., the second TTI 225-b) and the TTI 225 of the scheduled transmission 215 (e.g., the nth TTI 225-n).

[0133]

[0143] It is important to define the scheduling offset 220 based on the last PDCCH candidate 210-b of the set of PDCCH candidates 210 (rather than the first / earliest PDCCH candidate 210 or some other PDCCH candidate). In particular, the UE 115-a may need to adjust reception parameters (e.g., perform a beam switching procedure) between the first time the UE 115-a is scheduled to perform a communication and the second time the UE 115-a is set to perform the communication. Thus, the UE 115-a may require some minimum amount of time between the latest time the UE 115-a may be scheduled for a communication and the time the communication is scheduled. In this regard, by defining the scheduling offset 220 relative to the last PDCCH candidate 210 from which the UE 115-a may receive a DCI, scheduling the communication may ensure that the UE 115-a has enough time between the scheduling DCI and the scheduled communication to adjust reception parameters. In comparison, if the scheduling offset 220 were defined for the first / earliest PDCCH candidate 210-a (or some other PDCCH candidate 210), the UE 115-a may receive the scheduling DCI after the start of the scheduling offset 220, and may not be given enough time to adjust reception parameters between the scheduling DCI 220 and the scheduled communication.

[0134]

[0144] In some implementations, the scheduling offset 220 for a transmission 215 scheduled by DCI repetition may depend on the type of transmission 215. For example, as described in further detail later herein with respect to Figures 3-10, the UE 115-a and the base station 105-a may be configured to apply a scheduling offset 220-a when the scheduled transmission 215 includes CSI-RS and may be configured to apply a scheduling offset 220-b when the scheduled transmission 215 includes SRS.

[0135]

[0145] In some cases, the UE 115-a may be pre-configured with various rules for determining the scheduling offset 220 for a transmission 215 that is scheduled by a repetition of DCI received in the PDCCH candidates 210. Additionally or alternatively, the rules for determining the scheduling offset 220 may be signaled by the base station 105-a to the UE 115-a (e.g., via RRC signaling). Various rules and signaling used by the UE 115-a and the base station 105-a to determine the scheduling offset 220 (and thus the relative timing) of a transmission 215 that is scheduled by a repetition of DCI received in the PDCCH candidates 210 may be further shown and described with respect to FIGS. 3-10.

[0136]

[0146] 3 illustrates an example of a resource allocation scheme 300 that supports techniques for timing relationships for PDCCH repetitions in accordance with aspects of the disclosure. In some examples, the resource allocation scheme 300 may implement or be implemented by aspects of wireless communications system 100, wireless communications system 200, or both. The resource allocation scheme 300 includes a resource configuration 305 that indicates a scheduling offset 320 for a CSI-RS 315 that is scheduled over one or more repetitions of DCI received within a set of linked PDCCH candidates 310.

[0137]

[0147] For example, as previously described herein, the UE 115 may monitor a set of downlink control channel candidates (e.g., PDCCH candidates 310) that are associated with each other. In other words, the UE 115 may monitor a set of PDCCH candidates 310 that are linked with each other for PDCCH repetitions. In some aspects, the set of PDCCH candidates 310 monitored by the UE 115 may include at least a first PDCCH candidate 310-a in a first TTI (e.g., a first slot 325-a) and a last PDCCH candidate 310-b in a second TTI (e.g., a second slot 325-b) that is after (e.g., subsequent to) the first TTI.

[0138]

[0148] The UE 115 may then receive one or more repetitions of the DCI from the base station 105. The UE 115 may receive one or more repetitions of the DCI in the first PDCCH candidate 310-a, the last PDCCH candidate 310-b, or both. In this regard, the UE 115 may receive the one or more repetitions of the DCI based on monitoring the set of PDCCH candidates 310. The one or more repetitions of the DCI may include any DCI format (e.g., DCI formats 0_1, 0_2) that may be received and / or decoded by the UE 115.

[0139]

[0149] In some aspects, the repetition of DCI may schedule transmissions between the base station 105 and the UE 115. For example, as shown in FIG. 3, the repetition of DCI received in the PDCCH candidate 310 may schedule the CSI-RS 315 in the fourth slot 325-d. In some aspects, the repetition of DCI may indicate a set of resources available by the UE 115 to receive the CSI-RS 315. In some cases, one or more repetitions of the DCI (e.g., UL DCI) may include an indication of a trigger state configuration. In particular, the repetition of DCI may indicate a trigger state configuration for the CSI-RS 315 included within a set of trigger state configurations indicated via an RRC message received from the base station 105 (e.g., may indicate a trigger state configuration included within a set of RRC configured trigger state configurations). The trigger state configuration may be indicated within a CSI request field of the DCI.

[0140]

[0150] In some aspects, the UE 115 and / or the base station 105 may be configured to determine one or more TCI states based on a trigger state configuration indicated in the DCI. In particular, each CSI-RS resource may be associated with a trigger state and configured (e.g., via RRC) with an associated TCI state. In this regard, an indication of the trigger state configuration in the DCI may indicate (e.g., be associated with) one or more TCI states for transmission / reception of the CSI-RS 315.

[0141]

[0151] In some aspects, the UE 115, the base station 105, or both may determine and / or apply a scheduling offset 320 associated with a CSI-RS 315 that is scheduled by a repetition of DCI. The UE 115 and / or the base station 105 may determine / apply the scheduling offset based on an RRC message, monitoring PDCCH candidates 310, transmitting / receiving repetitions of DCI within the PDCCH candidates 310, or any combination thereof.

[0142]

[0152] In some aspects, the UE 115 and / or base station 105 may be configured to apply the scheduling offset 320 regardless of where the repetition of the DCI is detected within the set of PDCCH candidates 310. In particular, in some cases, the UE 115 and / or base station 105 may be configured to apply the scheduling offset 320 based on the timing of the last PDCCH candidate 310-b regardless of where (or how much) the repetition of the DCI is detected within the set of PDCCH candidates 310. For example, the UE 115 and / or base station 105 may be configured to apply the scheduling offset 320 regardless of whether the first repetition of the DCI is detected within the first PDCCH candidate 310-a, whether the second repetition of the DCI is detected within the last PDCCH candidate 310-b, or whether both the first and second repetitions of the DCI are detected within the first and last PDCCH candidates 310-a and 310-b, respectively.

[0143]

[0153] In some aspects, the scheduling offset 320 may be based on the timing of the last PDCCH candidate 310-b of the set of PDCCH candidates 310. In particular, the scheduling offset 320 may be based on the placement of the last PDCCH candidate 310-b within the second slot 325-b, the timing of the first and / or last symbol of the second slot 325-b associated with the last PDCCH candidate 310-b, or both. For example, as shown in FIG. 3, the scheduling offset 320 may include an offset between the last symbol of the last PDCCH candidate 310-b and the first symbol of the CSI-RS 315.

[0144]

[0154] In some aspects, the UE 115 and / or the base station 105 may be configured to determine one or more parameters associated with transmission / reception of the CSI-RS 315 based on a comparison of a duration of the scheduling offset 320 in the time domain to a duration of a beam switching threshold associated with the UE 115. For example, the UE 115 and the base station 105 may be configured to determine a QCL configuration associated with the CSI-RS 315 based on a comparison of the scheduling offset 320 to a beam switching threshold and / or an adjusted beam switching threshold associated with the UE 115. Details related to determining parameters for the CSI-RS 315 are described in further detail later herein with respect to FIG.

[0145]

[0155] Upon determining the scheduling offset 320, the UE 115 may receive from the base station 105 the CSI-RS 315 scheduled by the repetition of the DCI. The UE 115 may receive the CSI-RS 315 based on (e.g., according to) the scheduling offset 320 applied based on the timing of the last PDCCH candidate 310-b, and the base station 105 may transmit it based thereon. For example, as previously mentioned herein, the scheduling offset 320 may define an offset between the last symbol of the last PDCCH candidate 310-b and the first symbol of the CSI-RS 315. Additionally or alternatively, the UE 115 may receive the CSI-RS 315 based on parameters indicated via RRC signaling and / or repetition of the DCI, based on parameters (e.g., QCL configuration) determined according to a comparison of the scheduling offset 320 to the beam switching threshold (or adjusted beam switching threshold) of the UE 115, or based on any combination thereof.

[0146]

[0156] 4 illustrates an example of a resource allocation scheme 400 supporting techniques for timing relationships for PDCCH repetitions according to aspects of the disclosure. In some examples, the resource allocation scheme 400 may implement or be implemented by aspects of the wireless communications system 100, the wireless communications system 200, the resource allocation scheme 300, or any combination thereof. The resource allocation scheme 400 includes a resource configuration 405 that indicates a scheduling offset 420 for a set of SRS 415 that are scheduled over one or more repetitions of DCI received within a set of linked PDCCH candidates 410.

[0147]

[0157] For example, in some cases, the UE 115 may receive an RRC message from the base station 105, where the RRC message indicates a scheduling offset 420 for one or more transmissions scheduled via a PDCCH repetition. For example, the RRC message may indicate a scheduling offset 420 (e.g., “SlotOffset”) for an SRS (e.g., aperiodic SRS 415) that is scheduled via a DCI repetition. In some aspects, the scheduling offset 420 (e.g., SlotOffset) associated with an SRS that is scheduled via a DCI repetition may include an amount of TTIs (e.g., an amount of slots 425) between a TTI associated with the last PDCCH candidate 410-b in which a DCI repetition may be received and a TTI associated with the scheduled SRS 415. In other words, if the SRS 415 is scheduled via multiple repetitions of DCI received in the set of PDCCH candidates 410, the SRS 415 may be transmitted by the UE 115-b within an amount of slots 425 of the scheduling offset 420 after the slot associated with the last PDCCH candidate 410-b in the set of PDCCH candidates 410 (e.g., the amount of “SlotOffset” of slots 425).

[0148]

[0158] In some aspects, the RRC message may further indicate (e.g., configure) one or more additional parameters associated with the set of SRS 415. For example, if the SRS 415 scheduled via a PDCCH repetition includes a non-codebook resource set, the RRC message may indicate a non-zero power (NZP) CSI-RS 430 resource identifier. In some aspects, the resource for receiving the CSI-RS 430 associated with the SRS 415 may be located in the same TTI (e.g., the same slot 425) as the last PDCCH candidate 410-b.

[0149]

[0159] Additionally or alternatively, the UE 115 may receive from the base station 105 an indication of a TTI offset associated with transmission / reception of the CSI-RS 430. In some aspects, the CSI-RS 430 may be associated with an SRS 415 that is to be scheduled via DCI repetition, as described in further detail later herein. In some aspects, the indication of the TTI offset (e.g., "SlotOffset-CSI-RS 430") may be transmitted / received via an RRC message, a DCI message, a MAC-CE message, or any combination thereof. In this regard, in some cases, the UE 115 may receive the indication of the TTI offset (e.g., SlotOffset-CSI-RS 430) via an RRC message.

[0150]

[0160] In some aspects, the UE 115, the base station 105, or both may determine resources (e.g., a set of resources) for transmission / reception of the CSI-RS 430. In some aspects, the CSI-RS 430 may be associated with an SRS 415 that is to be scheduled via a repetition of DCI, as described in further detail later herein. In some implementations, the resources for the CSI-RS 430 may be placed in the same slot 425 as the last PDCCH candidate 410-b in which a repetition of DCI that schedules the associated non-codebook SRS 415 may be received. For example, as shown in FIG. 4, if the last PDCCH candidate 410-b is placed in the second slot 425-b, then the resources for the CSI-RS 430 may also be placed in the second slot 425-b.

[0151]

[0161] Additionally or alternatively, resources for CSI-RS 430 may be located in a different slot 425 than the slot 425 associated with the last PDCCH candidate 410-b (e.g., a different slot than the second slot 425-b shown in FIG. 4). In such a case, resources for CSI-RS 430 may be determined based on a TTI offset (e.g., SlotOffset-CSI-RS) indicated by the base station 105. For example, if the UE 115 and / or base station 105 determines the TTI offset (SlotOffset-CSI-RS), the wireless device may be configured to determine resources for transmission / reception of CSI-RS 430 based on the second slot 425-b associated with the last PDCCH candidate 410-b and the TTI offset. In particular, the TTI offset may define the amount of slots 425-b after the second slot 425-b that includes the last PDCCH candidate 410-b in which resources for CSI-RS 430 may be found. In other words, the resources for the CSI-RS 430 may be found in the amount of “TTI offset” of the slot 425 after the second slot 425-b of the last PDCCH candidate 410-b (e.g., the amount of “SlotOffset-CSI-RS” of the slot 425). In this regard, the second slot 425-b associated with the last PDCCH candidate 410-b may be used as a “reference slot 425” for determining the slot 425 in which the scheduled SRS 415 may be transmitted, the slot 425 in which the CSI-RS 430 associated with the scheduled SRS 415 may be received, or both.

[0152]

[0162] In some aspects, the UE 115 may monitor a set of downlink control channel candidates (e.g., PDCCH candidates 410) associated with each other. In other words, the UE 115 may monitor a set of PDCCH candidates 410 linked with each other for PDCCH repetition. In some aspects, the set of PDCCH candidates 410 monitored by the UE 115 may include at least a first PDCCH candidate 410-a in a first TTI (e.g., a first slot 425-a) and a last PDCCH candidate 410-b in a second TTI (e.g., a second slot 425-b) that is after (e.g., subsequent to) the first slot 425-a. In some aspects, the UE 115 may monitor the set of PDCCH candidates 410 based on receiving an RRC message, receiving a TTI offset (SlotOffset-CSI-RS), determining resources for CSI-RS 430, or any combination thereof.

[0153]

[0163] The UE 115 may then receive one or more repetitions of DCI in the first PDCCH candidate 410-a, the last PDCCH candidate 410-b, or both from the base station 105. In this regard, the UE 115 may receive one or more repetitions of DCI based on receiving an RRC message, receiving a TTI offset, determining resources for the CSI-RS 430, monitoring the set of PDCCH candidates 410, or any combination thereof. The one or more repetitions of DCI may include any DCI format that can be received and / or decoded by the UE 115, including UE-specific DCI, group-common DCI, or both. For example, the DCI (e.g., DL DCI) may include a format for triggering aperiodic SRS, including DL DCI format 1_1 or 1_2, UL DCI format 0_1 ​​or 0_2, group-common DCI format 2_3, or any combination thereof.

[0154]

[0164] In some aspects, a repetition of a DCI may schedule a set of SRSs 415 (e.g., a set of aperiodic SRSs 415) to be transmitted from the UE 115 to the base station 105. In some aspects, a repetition of a DCI may indicate a set of resources available by the UE 115 for transmitting the set of SRSs 415. For example, an SRS request field in a repetition of a DCI may indicate one or more SRS resource sets for transmitting the set of SRSs 415. In some cases, one or more repetitions of a DCI (e.g., a UL DCI) may include an indication of a trigger state configuration. In some cases, a mapping between SRS resource sets available for transmission of a set of SRSs 415 and SRS request code points (e.g., 01, 10, 11) may be provided as part of an RRC parameter (e.g., aperiodicSRS-ResourceTrigger, aperiodicSRSResourceTriggerList) indicated via the RRC message at 805, the repetition of a DCI at 825, or both.

[0155]

[0165] In some aspects, the UE 115 may receive the CSI-RS 430 from the base station 105. In some aspects, the CSI-RS 430 may be associated with a set of SRS 415 that is scheduled by a repetition of DCI received in the set of PDCCH candidates 410. The UE 115 may receive the CSI-RS 430 based on, and the base station 105 may transmit it based on, an RRC message, a TTI offset, determining resources for the CSI-RS 430, monitoring the PDCCH candidates 410, a repetition of DCI received in the PDCCH candidates 410, or any combination thereof.

[0156]

[0166] For example, the UE 115 may receive the CSI-RS 430 within the determined resources for the CSI-RS 430. In this regard, in some implementations, the CSI-RS 430 may be received within the same TTI (e.g., the same slot 425-b) as the last PDCCH candidate 410-b. Additionally or alternatively, if the UE 115 and / or base station 105 determines / applies a TTI offset (SlotOffset-CSI-RS), the CSI-RS 430 may be received within some amount of slots 425 following the second slot 425-b associated with the last PDCCH candidate 410-b, where the amount of slots 425 is based on the TTI offset.

[0157]

[0167] Upon receiving the CSI-RS 430, the UE 115 may perform one or more measurements for the CSI-RS 430. The UE 115 may perform the measurements based on receiving an RRC message, receiving a TTI offset, determining resources for the CSI-RS 430, monitoring the PDCCH candidates 410, receiving repetitions of DCI received in the PDCCH candidates 410, receiving the CSI-RS 430, or any combination thereof.

[0158]

[0168] In some implementations, the UE 115 may determine one or more parameters associated with the transmission of the set of SRS 415 scheduled by the repetition of the DCI. The parameters associated with the SRS 415 may include, but are not limited to, a precoder to be used for the transmission of the SRS 415. In some aspects, the UE 115 may determine the one or more parameters based on one or more measurements performed on the CSI-RS 430. For example, the UE 115 may determine (e.g., calculate) a precoder to be used for the transmission of the set of SRS 415 based on measurements performed on the NZP CSI-RS 430.

[0159]

[0169] In some aspects, the UE 115, the base station 105, or both may determine and / or apply a scheduling offset 420 associated with a set of SRSs 415 that are scheduled by a repetition of DCI. In some aspects, the UE 115 and / or the base station 105 may be configured to apply the scheduling offset 420 regardless of where in the set of PDCCH candidates 410 the repetition of DCI is detected. In particular, in some cases, the UE 115 and / or the base station 105 may be configured to apply the scheduling offset 420 based on the timing of the last PDCCH candidate 410-b regardless of where (or how much) in the set of PDCCH candidates 410 the repetition of DCI is detected. For example, the UE 115 and / or the base station 105 may be configured to apply the scheduling offset 420 regardless of whether a first repetition of a DCI is detected in the first PDCCH candidate 410-a, whether a second repetition of the DCI is detected in the last PDCCH candidate 410-b, or whether both the first and second repetitions of the DCI are detected in the first PDCCH candidate 410-a and the last PDCCH candidate 410-b, respectively.

[0160]

[0170] In some aspects, the scheduling offset 420 may be based on the timing of the last PDCCH candidate 410-b of the set of PDCCH candidates. In particular, the scheduling offset 420 may be based on the placement of the last PDCCH candidate 410-b within the second slot 425-b, the first and / or last symbol of the second slot 425-b associated with the last PDCCH candidate 410-b, or both. For example, if the transmission scheduled by the repetition of the DCI includes a set of SRSs 415, the scheduling offset 420 may include an amount of slots 425 between the second slot 425-b of the last PDCCH candidate 410-b and the slot 425 in which the set of SRSs 415 is scheduled (e.g., the sixth slot 425-f).

[0161]

[0171] The UE 115 may transmit a set of SRS 415 scheduled by the DCI repetition based on (e.g., according to) a scheduling offset 420 applied based on the timing of the last PDCCH candidate 410-b. For example, the UE 115 may transmit a set of SRS 415 after a scheduling offset 420 (e.g., SlotOffset) applied based on a second slot 425-b of the last PDCCH candidate 410-b. In other words, the UE 115 may transmit a set of SRS 415 within a slot 425 (e.g., the sixth slot 425-f) that is an amount of slots 425 after the second slot 425-b associated with the last PDCCH candidate 410-b, where the amount of slots 425 is based on (e.g., defined by) the scheduling offset 420 (e.g., SlotOffset).

[0162]

[0172] In this regard, the UE 115 may transmit, and the base station 105 may receive, the set of SRS 415 based on sending / receiving an RRC message, sending / receiving a TTI offset, determining resources for CSI-RS 430, monitoring PDCCH candidates 410, sending / receiving repetitions of DCI, receiving CSI-RS 430, performing measurements on CSI-RS 430, determining parameters for the set of SRS 415, determining / applying a scheduling offset 420, or any combination thereof. For example, the UE 115 may transmit the set of SRS 415 based on (e.g., according to) using a determined precoder for the set of SRS 415. Thus, the UE 115 may transmit the set of SRS based on receiving the CSI-RS 430.

[0163]

[0173] In some cases, the UE 115 may receive a DCI 435 from the base station 105 that schedules an uplink transmission (e.g., PUSCH transmission 440) from the UE 115 to the base station 105. In particular, the DCI 435 may schedule a non-codebook based PUSCH transmission 440. In some aspects, the base station 105 may transmit the DCI 435 (e.g., UL DCI 435) based on receiving the set of SRS 415. In some aspects, the DCI 435 may indicate a set of resources available by the UE 115 for the transmission of the PUSCH transmission 440. The UE 115 may then transmit the uplink transmission (e.g., PUSCH transmission 440) scheduled by the DCI 435 to the base station 105. In this regard, the UE 115 may transmit an uplink transmission (e.g., PUSCH transmission 440) message based on receiving the DCI 435. For example, the UE 115 may transmit a PUSCH transmission 440 (eg, a non-codebook based PUSCH transmission 440) within the set of resources indicated by the DCI 435.

[0164]

[0174] 5 illustrates an example of a resource allocation scheme 500 supporting techniques for timing relationships for PDCCH repetitions according to aspects of the disclosure. In some examples, the resource allocation scheme 500 may implement or be implemented by aspects of the wireless communications system 100, the wireless communications system 200, the resource allocation schemes 300-400, or any combination thereof. The resource allocation scheme 500 includes a resource configuration 505 indicating a scheduling offset 520 for a PDSCH transmission 515 and / or a CSI-RS 535 that is scheduled via one or more repetitions of DCI received within a set of linked PDCCH candidates 510.

[0165]

[0175] For example, in some cases, the UE 115 may receive an RRC message from the base station 105. In some aspects, the RRC message may indicate one or more minimum scheduling delays 530 (Δ) associated with PDCCH decoding. Additionally or alternatively, the UE 115 may be configured (e.g., pre-configured) with one or more minimum scheduling delays 530. In some cases, the one or more minimum scheduling delays 530 may be configured in the UE 115 to avoid excessive buffering of downlink samples due to PDCCH decoding. In particular, the minimum scheduling delays 530 may be configured to allow the UE 115 sufficient time to process a PDCCH transmission (e.g., a repetition of a DCI) when the PDCCH channel and the PDSCH channel on which the transmission is scheduled have different SCSs. In some aspects, the minimum scheduling delays 530 may define a minimum duration (e.g., a minimum number of symbols, a minimum amount of TTIs, a minimum amount of slots) between a DCI scheduling a transmission and the start of a transmission scheduled by the DCI.

[0166]

[0176] In some aspects, the UE 115 may monitor a set of downlink control channel candidates (e.g., PDCCH candidates 510) associated with each other. In other words, the UE 115 may monitor a set of PDCCH candidates 510 linked with each other for PDCCH repetition. In some aspects, the set of PDCCH candidates 510 monitored by the UE 115 may include at least a first PDCCH candidate 510-a in a first TTI (e.g., a first slot 525-a) and a last PDCCH candidate 510-b in a second TTI (e.g., a second slot 525-b) that is after (e.g., after) the first slot 525-a. In some aspects, the UE 115 may monitor the set of PDCCH candidates 510 based on receiving an RRC message.

[0167]

[0177] In some aspects, the UE 115 may receive one or more repetitions of DCI in the first PDCCH candidate 510-a, the last PDCCH candidate 510-b, or both, from the base station 105. In this regard, the UE 115 may receive the one or more repetitions of DCI based on receiving an RRC message, monitoring the set of PDCCH candidates 510, or both. The one or more repetitions of DCI may include any DCI format that may be received and / or decoded by the UE 115.

[0168]

[0178] In some aspects, the repetition of DCI may schedule transmissions between the base station 105 and the UE 115. For example, as shown in FIG. 5, the DCI message may schedule the transmission of the PDSCH 515, the CSI-RS 535 (e.g., aperiodic CSI-RS 535), or both. In some aspects, the DCI message may indicate a set of resources available by the UE 115 for transmitting the PDSCH 515 and / or receiving the CSI-RS 535. In some cases, the repetition of DCI may schedule the transmission of the PDSCH 515 and / or the CSI-RS 535 in the same or different component carriers as the control channel (e.g., PDCCH) on which the repetition of DCI was received (e.g., cross-carrier scheduling). For example, the PDCCH candidate 510 (and thus the DCI repetition) may be associated with a PDCCH having a first SCS, and the transmission of the PDSCH 515 and / or the CSI-RS 535 may be scheduled on a different channel (e.g., the PDSCH 515) associated with a second SCS that is different from the first SCS.

[0169]

[0179] In some implementations, the UE 115, the base station 105, or both may determine an SCS associated with a channel on which a repetition of the DCI was received, a channel on which a transmission of the PDSCH 515 and / or a CSI-RS 535 is scheduled, or both. The UE 115 and / or the base station 105 may determine the SCS of the respective channel based on monitoring the PDCCH candidates 510, transmitting / receiving the repetition of the DCI, or both. For example, the UE 115 and / or the base station 105 may determine a first SCS associated with a downlink control channel (e.g., PDCCH) on which at least one repetition of the DCI was received and may determine a second SCS associated with a channel (e.g., PDSCH 515) on which a transmission of the PDSCH 515 / CSI-RS 535 scheduled by the repetition of the DCI will be implemented.

[0170]

[0180] The UE 115, the base station 105, or both may determine a minimum scheduling delay 530 associated with a scheduled PDSCH transmission 515 and / or a CSI-RS 535. In some aspects, the UE 115 and / or the base station 105 may determine the minimum scheduling delay 530 based on transmitting / receiving RRC messages, monitoring PDCCH candidates 510, transmitting / receiving repetitions of DCI, determining the SCS of the respective channels, or both.

[0171]

[0181] As previously mentioned herein, the minimum scheduling delay 530 may define a minimum duration (e.g., a minimum number of OFDM symbols, a minimum amount of TTIs, a minimum amount of slots 525) between a DCI scheduling a transmission and the start of a transmission scheduled by the DCI. For example, the minimum scheduling delay 530 may define a minimum amount of symbols (e.g., OFDM symbols) between the last symbol of the last PDCCH candidate 510-b and the first symbol associated with a scheduled PDSCH 515 transmission and / or CSI-RS 535.

[0172]

[0182] In some aspects, the value of the minimum scheduling delay 530 may be based on the SCS of a control channel (e.g., PDCCH) on which the repetition of the DCI is received. In particular, the minimum scheduling delay 530 may be based on whether the SCS of the PDCCH is shorter (or longer) than the SCS of the channel (e.g., PDSCH 515) on which the transmission of the PDSCH 515 and / or the CSI-RS 535 is scheduled. In some aspects, the SCS of the PDCCH (μ PDCCH ) SCS, DCI (μ PDSCH , μ CSI-RS If the minimum scheduling delay 530 value is shorter than the SCS of the channel associated with the PDSCH 515 / CSI-RS 535 that is scheduled by the repetition of the PDCCH (μ PDCCH ) SCS is DCI (μ PDSCH , μ CSI-RS ) is greater than or equal to the SCS of the channel associated with the PDSCH 515 / CSI-RS 535 that is scheduled by the repetition of

[0173]

[0183] As an example, the UE 115 and / or base station 105 may determine a first SCS associated with a downlink control channel (e.g., PDCCH) on which at least one repetition of the DCI was received and may determine a second SCS associated with a channel (e.g., PDSCH 515) on which a transmission of the PDSCH 515 and / or CSI-RS 535 scheduled by the repetition of the DCI will be performed. In this example, the UE 115 and base station 105 may determine a minimum scheduling delay 530 based on a comparison of the first SCS and the second SCS. In particular, the UE 115 and / or base station 105 may be configured to perform quantization to determine the minimum scheduling delay 530 based on a comparison of the first SCS and the second SCS.

[0174]

[0184] In some aspects, the UE 115, the base station 105, or both determine and / or apply a scheduling offset 520 associated with a transmission scheduled by a repetition of DCI. The UE 115 and / or the base station 105 may determine / apply the scheduling offset 520 based on transmitting / receiving an RRC message, monitoring PDCCH candidates 510, transmitting / receiving a repetition of DCI, determining the SCS of the respective channel, determining a minimum scheduling delay 530, or any combination thereof.

[0175]

[0185] In some aspects, the UE 115 and / or base station 105 may be configured to apply the scheduling offset 520 regardless of where the repetition of the DCI is detected within the set of PDCCH candidates 510. In particular, in some cases, the UE 115 and / or base station 105 may be configured to apply the scheduling offset 520 based on the timing of the last PDCCH candidate 510-b regardless of where (or how much) the repetition of the DCI is detected within the set of PDCCH candidates 510. For example, the UE 115 and / or base station 105 may be configured to apply the scheduling offset 520 regardless of whether the first repetition of the DCI is detected within the first PDCCH candidate 510-a, whether the second repetition of the DCI is detected within the last PDCCH candidate 510-b, or whether both the first and second repetitions of the DCI are detected within the first PDCCH candidate 510-a and the last PDCCH candidate 510-b, respectively.

[0176]

[0186] In some aspects, the scheduling offset 520 may be based on the timing of the last PDCCH candidate 510-b of the set of PDCCH candidates 510. In particular, the scheduling offset 520 may be based on the placement of the last PDCCH candidate 510-b within the second slot 525-b, based on the first and / or last symbol of the second slot 525-b associated with the last PDCCH candidate 510-b, or both. In some aspects, the scheduling offset 520 may be based on the minimum scheduling delay 530. For example, in some cases, the scheduling offset 520 may be greater than or equal to the minimum scheduling delay 530. For example, if the UE 115 and the base station 105 determine the minimum scheduling delay 530 to be four slots 525, then the scheduling offset 520 may be determined to be greater than or equal to four slots 525.

[0177]

[0187] The UE 115 may then receive from the base station 105 a PDSCH 515 transmission and / or a CSI-RS 535 that is scheduled by the repetition of the DCI. The UE 115 may receive the PDSCH 515 transmission and / or CSI-RS 535 based on (e.g., in accordance with) the scheduling offset 520, the minimum scheduling delay 530, or both, and the base station 105 may transmit it based thereon.

[0178]

[0188] For example, the UE 115 may receive, and the base station 105 may transmit, the PDSCH 515 transmission and / or CSI-RS 535 based on (e.g., according to) the minimum scheduling delay 530 and / or scheduling offset 520 applied based on the timing of the last PDCCH candidate 510-b, where the minimum scheduling delay 530 is less than or equal to the scheduling offset 520. For example, if the UE 115 and the base station 105 determine the minimum scheduling delay 530 to be four slots 525, the scheduling offset 520 may be determined to be five slots 525. In this example, the base station 105 may transmit, and the UE 115 may receive, the PDSCH 515 transmission and / or CSI-RS 535 in the five slots 525 following the second slot 525-b associated with the last PDCCH candidate 510-b.

[0179]

[0189] The techniques described herein may provide improved scheduling of wireless communications. In particular, by defining signaling, rules, and / or configurations that enable the UE 115 and base station 105 to determine the timing of scheduled transmissions (e.g., PDSCH 515 transmissions, CSI-RS 535) via PDCCH repetitions, the techniques described herein may enable the UE 115 and base station 105 to efficiently determine the timing of scheduled transmissions. Furthermore, by enabling wireless devices to more efficiently determine the timing of scheduled transmissions via PDCCH repetitions, the techniques described herein may enable more widespread use of communications using PDCCH repetitions within wireless communications systems, thereby improving reliability of wireless communications, improving transmit diversity, and further protecting wireless communications against interference.

[0180]

[0190] 6 illustrates an example of a resource allocation scheme 600 supporting techniques for timing relationships for repetitions of a PDCCH according to aspects of the disclosure. In some examples, the resource allocation scheme 600 may implement or be implemented by aspects of the wireless communications system 100, the wireless communications system 200, the resource allocation schemes 300-500, or any combination thereof. The resource allocation scheme 600 includes a resource configuration 605 indicating a scheduling offset 620 (e.g., a minimum scheduling offset 620) for a PDSCH transmission 615 and / or a PUSCH transmission 630 that is scheduled via one or more repetitions of DCI received within a set of linked PDCCH candidates 610.

[0181]

[0191] For example, in some implementations, the UE 115 may receive an RRC message from the base station 105. In some aspects, the RRC message may indicate one or more minimum scheduling offsets 620 associated with a transmission scheduled by the base station 105. In some cases, the one or more minimum scheduling offsets 620 may be configured in the UE 115 to reduce power consumption in the UE 115 and the base station 105. In some cases, the minimum scheduling offset 620 may include one or more K0 values ​​(e.g., minK0) associated with the scheduled PDSCH transmission 615, one or more K2 values ​​(e.g., minK2) associated with the scheduled PUSCH transmission 630, or both. For example, in some cases, the UE 115 may be configured with up to two values ​​for each of minK0 and minK2. In some aspects, the minimum scheduling offset 620 may define a minimum duration (e.g., a minimum amount of TTI, a minimum amount of slots 625) between a DCI scheduling a transmission and a slot including a transmission scheduled by the DCI.

[0182]

[0192] In some aspects, the UE 115 may monitor a set of downlink control channel candidates (e.g., PDCCH candidates 610) associated with each other. In other words, the UE 115 may monitor a set of PDCCH candidates 610 linked with each other for PDCCH repetition. In some aspects, the set of PDCCH candidates 610 monitored by the UE 115 may include at least a first PDCCH candidate 610-a in a first TTI (e.g., a first slot 625-a) and a last PDCCH candidate 610-b in a second TTI (e.g., a second slot 625-b) that is after (e.g., subsequent to) the first slot 625-a. In some aspects, the UE 115 may monitor the set of PDCCH candidates 610 based on receiving an RRC message that includes an indication of the minimum scheduling offset 620.

[0183]

[0193] The UE 115 may then receive one or more repetitions of DCI in the first PDCCH candidate 610-a, the last PDCCH candidate 610-b, or both, from the base station 105. In this regard, the UE 115 may receive the one or more repetitions of DCI based on receiving an RRC message, monitoring the set of PDCCH candidates 610, or both. The one or more repetitions of DCI may include any DCI format (e.g., DCI formats 0_1, 1_1) that may be received and / or decoded by the UE 115.

[0184]

[0194] In some aspects, the repetition of the DCI may schedule a transmission between the base station 105-a and the UE 115-a. For example, as shown in FIG. 6, the DCI may schedule a PDSCH transmission 615-a, a PUSCH transmission 630-a, or both. In some aspects, the DCI may indicate a set of resources usable by the UE 115 to receive the PDSCH transmission 615-a and / or the PUSCH transmission 630-b.

[0185]

[0195] In some aspects, the repetition of the DCI may include one or more bit fields indicating which minimum scheduling offset 620 is to be applied (e.g., which minimum scheduling offset 620 is active). For example, if the repetition of the DCI schedules a PDSCH transmission 615-a and the UE 115 is configured with two minK0 values ​​for the PDSCH transmission 615, the repetition of the DCI may indicate which minK0 value is to be applied to the minimum scheduling offset 620-a for performing the scheduled PDSCH transmission 615-a. As another example, if the repetition of the DCI schedules a PUSCH transmission 630-a and the UE 115 is configured with two minK2 values ​​for the PUSCH transmission 630, the repetition of the DCI may indicate which minK2 value is to be applied to the minimum scheduling offset 620-a for performing the scheduled PUSCH transmission 630-a.

[0186]

[0196] Additionally or alternatively, the repetition of the DCI may indicate a change in one or more values ​​of the minimum scheduling offset 620. In particular, the repetition of the DCI may indicate a change in one or more values ​​of the minimum scheduling offset indicator field of the repetition of the DCI. For example, if the UE 115 is configured with a first minK0 value and a second minK0 value for the PDSCH transmission 615, the repetition of the DCI may indicate a change to the first minK0 value (e.g., a modified minimum scheduling offset 620-b). In other words, the repetition of the DCI may indicate an adjusted minimum scheduling offset 620-b (e.g., an adjusted minK0 value, an adjusted minK2 value) that is different from the minimum scheduling offset 620-a (e.g., a minK0 value, a minK2 value) applied to the PDSCH transmission 615-a and / or the PUSCH transmission 630-a. In some cases, the indication of the change in the minimum scheduling offset 620 may also indicate an activation of the respective modified minimum scheduling offset 620. For example, continuing with the above example, if a DCI repetition indicates a change to a first minK0 value (e.g., a first minK0 value applied to minimum scheduling offset 620-a), the change to the first minK0 value may also serve as a selection of an adjusted (changed) first minK0 value (e.g., an adjusted minK0 value applied to minimum scheduling offset 620-b).

[0187]

[0197] If the DCI repetition indicates a change in the minimum scheduling offset 620, the DCI repetition may further indicate a scheduling offset 635 (e.g., an application delay 635). In some aspects, the scheduling offset 635 (e.g., an application delay) may indicate when a change to the minimum scheduling offset 620 is to be applied (e.g., when a change to the minK0 and / or minK2 values). In some aspects, the scheduling offset 635 may define an amount of slots, an amount of symbols, and / or an amount of TTIs relative to the last symbol of the second slot 625-b that includes the last PDCCH candidate 610-b.

[0188]

[0198] The UE 115, the base station 105, or both may determine and / or apply a scheduling offset 635 associated with a repetition of the DCI. In particular, the UE 115 and / or the base station 105 may determine that a change in one or more values ​​of the minimum scheduling offset 620-a is to be applied after the scheduling offset 635 applied based on the timing of the last PDCCH candidate 610-b. Applying the Scheduling Offset. The UE 115 and / or the base station 105 may determine / apply the minimum scheduling offset 635 based on transmitting / receiving an RRC message, monitoring the PDCCH candidates 610, transmitting / receiving a repetition of the DCI, determining a change in the minimum scheduling offset 620, or any combination thereof (e.g., may apply a change to the minimum scheduling offset 620-a after the scheduling offset 635).

[0189]

[0199] In some aspects, the UE 115 and / or base station 105 may be configured to apply the scheduling offset 635 regardless of where in the set of PDCCH candidates 610 the repetition of DCI is detected (e.g., apply one or more modifications to the minimum scheduling offset 620-a based on the scheduling offset 635). In particular, in some cases, the UE 115 and / or base station 105 may be configured to apply the scheduling offset 635 based on the timing of the last PDCCH candidate 610-b regardless of where (or how much) in the set of PDCCH candidates 610 the repetition of DCI is detected. For example, the UE 115 and / or the base station 105 may be configured to apply the scheduling offset 635 regardless of whether a first repetition of a DCI is detected in the first PDCCH candidate 610-a, whether a second repetition of the DCI is detected in the last PDCCH candidate 610-b, or whether both the first and second repetitions of the DCI are detected in the first PDCCH candidate 610-a and the last PDCCH candidate 610-b, respectively.

[0190]

[0200] In some aspects, the scheduling offset 635 may be based on the timing of the last PDCCH candidate 610-b of the set of PDCCH candidates 610. In particular, the scheduling offset 635 may be based on the placement of the last PDCCH candidate 610-b within the second slot 625-b, based on the first and / or last symbol of the second slot 625-b associated with the last PDCCH candidate 610-b, or both. For example, the scheduling offset 635 may define the amount of slots 625 (or amount of TTIs or symbols) following the second slot 625-b associated with the last PDCCH candidate 610-b.

[0191]

[0201] In some cases, the scheduling offset may define the amount of slots or symbols following the second slot 625-b that includes the last PDCCH candidate 610-b. For example, if the scheduling offset 635 indicates three slots 625, the UE 115 and / or base station 105 may be configured to apply one or more changes to the minimum scheduling offset 620-a after the end of the scheduling offset 635 that is applied based on the timing of the last PDCCH candidate 610-b. In this regard, since the changes to the minimum scheduling offset 620 are not implemented until the end of the scheduling offset 635, a scheduled PDSCH transmission 615 and / or PUSCH transmission 630 scheduled via a DCI message received before the end of the scheduling offset 635 may be associated with the old (e.g., unchanged) minimum scheduling offset 620-a. For example, a DCI message scheduling a PDSCH transmission 615 may be received within a PDCCH candidate 610-c within the scheduling offset 635. In this example, the PDSCH transmission 615 may be scheduled before the end of the scheduling offset 635 and therefore may be scheduled before the changes to the minimum scheduling offset 620-a are implemented (e.g., before the changes to the minK2 value are implemented). Thus, the PDSCH transmission 615 scheduled via the DCI received in the PDCCH candidate 610-c may be associated with the old, unchanged minimum scheduling offset 620-a (e.g., the unchanged minK2 value).

[0192]

[0202] In comparison, the UE 115 may receive a DCI message in the PDCCH candidate 610-d following the end of the scheduling offset 635, where the DCI message schedules a PDSCH 615-b and / or a PUSCH transmission 630-b. In this example, because the PDSCH 615-b and / or PUSCH transmission 630-b was scheduled following the end of the scheduling offset 635 (and thus following implementation of the changes to the minimum scheduling offset 620-z), the PDSCH 615-b and / or PUSCH transmission 630-b may be associated with an adjusted minimum scheduling offset 620-b (e.g., an adjusted minK2 value, an adjusted minK0 value).

[0193]

[0203] In this regard, which minK0 value and / or minK0 value (e.g., which minimum scheduling offset 620) is applied to the respective PDSCH transmission 615 and / or PUSCH transmission 630 may be based on the scheduling offset 635 (e.g., application delay). If the PDSCH transmission 615 and / or PUSCH transmission 630 is scheduled via a DCI received before the end of the scheduling offset 635, the old (e.g., unmodified) minimum scheduling offset 620-a is applied (e.g., unmodified minK2 value, minK0 value). Conversely, if the PDSCH transmission 615 and / or PUSCH transmission 630 is scheduled via a DCI received after the end of the scheduling offset 635, the new modified (e.g., adjusted) minimum scheduling offset 620-b is applied (e.g., adjusted minK2 value, adjusted minK0 value).

[0194]

[0204] The techniques described herein may provide improved scheduling of wireless communications. In particular, by defining signaling, rules, and / or configurations that enable the UE 115 and base station 105 to determine the timing of scheduled transmissions (e.g., PDSCH transmissions 615, PUSCH transmissions 630) via PDCCH repetitions, the techniques described herein may enable the UE 115 and base station 105 to efficiently determine the timing of scheduled transmissions. Furthermore, by enabling wireless devices to more efficiently determine the timing of scheduled transmissions via PDCCH repetitions, the techniques described herein may enable more widespread use of communications using PDCCH repetitions within wireless communications systems, thereby improving reliability of wireless communications, improving transmit diversity, and further protecting wireless communications against interference.

[0195]

[0205] 7 illustrates an example of a process flow 700 supporting techniques for timing relationships for repetitions of a PDCCH according to aspects of the disclosure. In some examples, the process flow 700 may implement or be implemented by aspects of the wireless communications system 100, the wireless communications system 200, the resource allocation schemes 300-600, or any combination thereof. For example, the process flow 700 may illustrate the UE 115-b monitoring a set of PDCCH candidates, receiving one or more repetitions of a DCI, applying a scheduling offset based on the last PDCCH candidate, and communicating with the base station 105-b based on the scheduling offset, as described with respect to FIGS. 1-6.

[0196]

[0206] In some cases, the process flow 700 may include a UE 115-a and a base station 105-b, which may be examples of corresponding devices described herein. In particular, the UE 115-b and the base station 105-b illustrated in FIG. 7 may include examples of the UE 115-a and the base station 105-a illustrated in FIG.

[0197]

[0207] In some examples, the operations illustrated in process flow 700 may be performed by hardware (including, e.g., circuits, processing blocks, logic components, and other components), code executed by a processor (e.g., software), or any combination thereof. Alternatives to the following may be implemented, with some steps performed in a different order than described, or not performed at all. In some cases, the steps may include additional features not mentioned below, or further steps may be added.

[0198]

[0208] At 705, the UE 115-b may receive an RRC message from the base station 105-b, where the RRC message indicates a set of trigger state configurations. The set of trigger state configurations may be associated with triggering CSI reporting on the PUSCH (e.g., trigger states for triggering aperiodic CSI reporting). For example, the UE 115-b may be configured with the set of trigger state configurations using an upper layer parameter AperiodicTriggerStateList via RRC signaling. In some aspects, each trigger state configuration in the set of trigger state configurations may be linked to a CSI-RS resource set, where the CSI-RS resource set may include multiple CSI-RS resources. In some implementations, a TCI state for each of the CSI-RS resources may be associated with the trigger state configuration.

[0199]

[0209] In some aspects, the RRC message received at 705 may include additional control information related to receiving / decoding the PDCCH repetitions at the UE 115-b. For example, the RRC message may configure the UE 115-b with one or more CORESETs, search space sets, monitoring opportunities, PDCCH candidates, or any combination thereof. Additionally, the RRC message may configure the UE 115-b with a set of resources for sending or receiving a transmission.

[0200]

[0210] At 710, the UE 115-b may monitor a set of downlink control channel candidates (e.g., PDCCH candidates) associated with each other. In other words, the UE 115-b may monitor a set of PDCCH candidates linked with each other for PDCCH repetition. In some aspects, the set of PDCCH candidates monitored by the UE 115-b may include at least a first PDCCH candidate in a first TTI (e.g., a first slot) and a last PDCCH candidate in a second TTI (e.g., a second TTI) that is after (e.g., after) the first TTI. In some aspects, the UE 115-b may monitor the set of PDCCH candidates based on receiving an RRC message at 705.

[0201]

[0211] At 715, the UE 115-b may receive one or more repetitions of the DCI from the base station 105-b. The UE 115 may receive one or more repetitions of the DCI in the first PDCCH candidate, the last PDCCH candidate, or both. In this regard, the UE 115-b may receive one or more repetitions of the DCI based on receiving the RRC message at 705, monitoring the set of PDCCH candidates at 710, or both. The one or more repetitions of the DCI may include any DCI format (e.g., DCI formats 0_1, 0_2) that may be received and / or decoded by the UE 115-b.

[0202]

[0212] In some aspects, the repetition of the DCI may schedule a transmission between the base station 105-b and the UE 115-b. For example, as shown in FIG. 7, the transmission scheduled by the DCI message may include the CSI-RS transmitted by the base station 105-b. In some aspects, the DCI message may indicate a set of resources usable by the UE 115-b to receive the CSI-RS. In some cases, one or more repetitions of the DCI (e.g., UL DCI) may include an indication of a trigger state configuration. In particular, the repetition of the DCI may indicate a trigger state configuration for the CSI-RS included in the set of trigger state configurations indicated via the RRC message received at 705. The trigger state configuration may be indicated in a CSI request field of the repetition of the DCI.

[0203]

[0213] In some cases, the trigger state configuration indicated via the DCI repetition may be associated with one or more TCI states for CSI-RS transmission / reception. In particular, the UE 115-b may be configured to determine the trigger state configuration based on the DCI and may be configured to determine a CSI-RS resource set, a corresponding TCI state, or both based on the trigger state configuration.

[0204]

[0214] At 720, the UE 115-b may receive a downlink transmission from the base station 105-b within a set of resources associated with receiving CSI-RS at the UE 115-b. The downlink transmission may include, but is not limited to, a PDSCH transmission, additional CSI-RS (e.g., aperiodic CSI-RS, periodic CSI-RS, semi-persistent CSI-RS), etc. In some aspects, the downlink transmission may indicate one or more TCI states for transmission / reception of the CSI-RS. In some cases, the TCI state indicated in the downlink transmission may be the same as or different from the TCI state associated with the trigger state configuration indicated via the DCI. As shown in further detail herein, the UE 115-b may be configured to determine a QCL state for receiving the CSI-RS based on the downlink transmission received at 720. In some aspects, the UE 115-b may receive a downlink transmission based on receiving an RRC message at 705, monitoring PDCCH candidates at 710, receiving one or more repetitions of a DCI at 715, or any combination thereof.

[0205]

[0215] At 725, the UE 115-b may transmit to the base station 105-b an indication of a beam switching threshold (e.g., beamSwitchTiming) at the UE 115-b. In some aspects, the beam switching threshold may include a timing metric associated with switching from one beam to another at the UE 115-b. As shown in further detail herein, the UE 115-b and / or the base station 105-b may be configured to determine parameters for transmitting / receiving CSI-RS scheduled by DCI repetition based on a comparison of the scheduling offset determined at 730 and the beam switching threshold at the UE 115-b.

[0206]

[0216] At 730, the UE 115-b, the base station 105-b, or both may determine and / or apply a scheduling offset associated with a transmission scheduled by a repetition of the DCI. The UE 115-b and / or the base station 105-b may determine / apply a scheduling offset at 725 based on sending / receiving an RRC message at 705, monitoring PDCCH candidates at 710, sending / receiving a repetition of the DCI at 715, sending / receiving a downlink transmission at 720, sending / receiving a beam switching threshold at 725, or any combination thereof.

[0207]

[0217] In some aspects, the UE 115-b and / or the base station 105-b may be configured to apply a scheduling offset regardless of where in the set of PDCCH candidates the repetition of the DCI is detected. In particular, in some cases, the UE 115-b and / or the base station 105-b may be configured to apply a scheduling offset based on the timing of the last PDCCH candidate regardless of where (or how much) in the set of PDCCH candidates the repetition of the DCI is detected. For example, the UE 115-b and / or the base station 105-b may be configured to apply a scheduling offset regardless of whether the first repetition of the DCI is detected in the first PDCCH candidate, whether the second repetition of the DCI is detected in the last PDCCH candidate, or whether both the first and second repetitions of the DCI are detected in the first and last PDCCH candidates, respectively.

[0208]

[0218] In some aspects, the scheduling offset may be based on the timing of the last PDCCH candidate of the set of PDCCH candidates. In particular, the scheduling offset may be based on the placement of the last PDCCH candidate within a TTI, based on the TTI associated with the last PDCCH candidate, or both. For example, if the transmission scheduled by the repetition of DCI includes CSI-RS, the scheduling offset may include an offset between the last symbol of the last PDCCH candidate and the first symbol of CSI-RS (as shown in scheduling offset 220-a shown in FIG. 2 and scheduling offset 320 shown in FIG. 3).

[0209]

[0219] At 735, the UE 115-b, the base station 105-b, or both may determine a timing delay. In some aspects, the timing delay may be associated with the transmission / reception of the CSI-RS. Furthermore, the timing delay may indicate an additional beam switching delay at the UE 115-b and / or the base station 105-b and thus may be associated with the beam switching threshold reported at 725.

[0210]

[0220] In particular, in some cases, the timing delay (d) may be associated with cross-carrier scheduling in which a PDCCH candidate (e.g., a repetition of DCI) is transmitted in a first component carrier and a scheduled CSI-RS is scheduled in a second component carrier with a different SCS compared to the first component carrier. Thus, in some cases, the timing delay determined at 735 may be correlated with the SCS of the component carrier associated with the PDCCH candidate, the SCS of the component carrier associated with the scheduled CSI-RS, or both. For example, in some cases, the UE 115-b and / or the base station 105-b may determine a timing delay associated with the CSI-RS based on the SCS of the downlink control channel (e.g., PDCCH) in which the repetition of DCI was received at 715. For example, the timing delay (d) may be defined as an amount of symbols (e.g., PDCCH symbols) and may be determined based on the SCS of the PDCCH (μ PDCCH ) may be correlated with SCS.

[0211] [Table 1]

[0212]

[0221] At 740, the UE 115-b, the base station 105-b, or both may determine an adjusted beam-switching threshold associated with the UE 115-b. In some aspects, the UE 115-b and / or the base station 105-b may determine the adjusted beam-switching threshold based on the beam-switching threshold reported at 725, determining the timing delay at 735, or both. In particular, the UE 115-b and / or the base station 105-b may be configured to determine the adjusted beam-switching threshold by applying the determined timing delay (d) to the beam-switching threshold of the UE 115-b.

[0213]

[0222] For example, in some cases, the UE 115-b and / or the base station 105-b may be configured to use the formula BST Adj =BST+d(2 μCSI-RS / 2 μPDCCH ) where BST is the beam switching threshold of the UE 115-b (e.g., the beam switching threshold reported in 725) and BST Adj is the adjusted beam switching threshold, d is the timing delay determined in 735, μCSI-RS is the SCS associated with the component carrier on which the CSI-RS is scheduled, and μPDCCH is the SCS associated with the control channel (e.g., PDCCH) on which the DCI repetition was received in 715.

[0214]

[0223] The UE 115-b, the base station 105-b, or both may compare the beam switching threshold, the adjusted beam switching threshold, or both to the scheduling offset at 745. In some aspects, the UE 115-b and / or the base station 105-b may compare the beam switching threshold and / or the adjusted beam switching threshold to the scheduling offset based on transmitting / receiving an RRC message at 705, monitoring PDCCH candidates at 710, transmitting / receiving repetitions of DCI at 715, transmitting / receiving a beam switching threshold at 725, determining a scheduling offset at 730, determining a timing delay at 735, determining the adjusted beam switching threshold at 745, or any combination thereof.

[0215]

[0224] At 750, the UE 115-b, the base station 105-b, or both may determine one or more QCL configurations for CSI-RS transmission / reception scheduled by the DCI repetition. In some aspects, the UE 115-b and / or the base station 105-b may be configured to determine the QCL configuration based on a comparison of a scheduling offset with a beam switching threshold (or an adjusted beam switching threshold). In particular, the QCL configuration associated with CSI-RS transmission / reception may be based on whether the scheduling offset determined at 745 (e.g., an offset between the last symbol of the last PDCCH candidate and the first symbol of the CSI-RS) is less than a beam switching threshold (BST). Additionally or alternatively, if the UE 115-b and / or the base station 105-b are configured to apply an adjusted beam switching threshold, the QCL configuration associated with CSI-RS transmission / reception may be based on whether the scheduling offset determined at 745 (e.g., an offset between the last symbol of the last PDCCH candidate and the first symbol of the CSI-RS) is less than the adjusted beam switching threshold (BST). Adj ) is smaller than

[0216]

[0225] For example, the scheduling offset (SO) is greater than or equal to the beam switching threshold (or an adjusted beam switching threshold) (for example, SO≧BST or SO≧BST Adj If the scheduling offset (SO) is greater than or equal to a beam switching threshold (or an adjusted beam switching threshold), the QCL configuration associated with the CSI-RS may be based on one or more TCI states associated with the trigger state configuration indicated via the DCI repetition received at 715. For example, if the scheduling offset (SO) is greater than or equal to a beam switching threshold (or an adjusted beam switching threshold), the QCL configuration may be indicated in the TCI state for the aperiodic CSI-RS in the CSI trigger state configuration indicated in the CSI field of the DCI repetition.

[0217]

[0226] As another example, the scheduling offset (SO) is smaller than the beam switching threshold (or the adjusted beam switching threshold) (e.g., SO <BSTまたはSO<BST Adj 7, the QCL configuration associated with the CSI-RS may be based on one or more TCI states indicated in the downlink transmission received at 720. In this regard, if the scheduling offset (SO) is less than a beam switching threshold (or an adjusted beam switching threshold) and there is another downlink transmission with the indicated TCI state received in the same resource for the CSI-RS, the UE 115-b and / or the base station 105-b may be configured to apply the QCL configuration of the downlink transmission for the CSI-RS (e.g., the downlink transmission received at 720). For example, if the scheduling offset (SO) is greater than or equal to the beam switching threshold (or an adjusted beam switching threshold), the QCL configuration may be indicated in the TCI state for the aperiodic CSI-RS in the CSI trigger state configuration indicated in the recurring CSI field of the DCI.

[0218]

[0227] Additionally or alternatively, the scheduling offset (SO) is less than the beam switching threshold (or the adjusted beam switching threshold) (e.g., SO <BSTまたはSO<BST Adj For example, if the scheduling offset (SO) is less than the beam switching threshold (or an adjusted beam switching threshold) (e.g., SO <BSTまたはSO<BST AdjIf the QCL configuration is determined to be the lowest controlResourceSetId in the last slot in which one or more CORESETs in the active BWP of the serving cell of the base station 105-b are monitored, the UE 115-b and / or the base station 105-b may determine a QCL configuration associated with a CORESET in the last TTI of the search space set monitored by the UE 115-b. For example, if one default beam is configured and at least one CORESET is configured, the QCL configuration may be associated with a CORESET associated with the search space set monitored by the UE 115-b in the lowest controlResourceSetId in the last slot in which one or more CORESETs in the active BWP of the serving cell of the base station 105-b are monitored.

[0219]

[0228] As another example, the scheduling offset (SO) is smaller than the beam switching threshold (or the adjusted beam switching threshold) (e.g., SO <BSTまたはSO<BST Adj If the QCL configuration is 0, the UE 115-b and / or the base station 105-b may determine the QCL configuration associated with the lowest activated TCI state of the serving cell associated with the CSI-RS. For example, in the case of cross-carrier scheduling where there is no CORESET configured in the cell where the CSI-RS is to be received, the QCL configuration may be associated with the activated TCI state of the lowest ID applicable to the PDSCH within the active BWP of the cell where the CSI-RS is to be received. It should be noted herein that other configurations may be used in the case where more than one QCL configuration may apply to the CSI-RS.

[0220]

[0229] At 755, the UE 115-b, the base station 105-b, or both may determine one or more parameters related to CSI-RS transmission / reception scheduled by the DCI repetition. In some aspects, the UE 115-b and / or the base station 105-b may be configured to determine the CSI-RS-related parameters based on a comparison of the scheduling offset and a beam switching threshold (or an adjusted beam switching threshold). The CSI-RS-related parameters may include, but are not limited to, a CSI trigger configuration, a TCI state, etc.

[0221]

[0230] In some aspects, the UE 115-b and the base station 105-b may communicate with each other via transmissions scheduled by repetition of DCI, where the transmissions are performed based on (e.g., according to) a scheduling offset, as shown at 760 of process flow 700.

[0222]

[0231] At 760, the UE 115-b may receive from the base station 105-b the CSI-RS that is scheduled by the repetition of the DCI. The UE 115-b may receive the CSI-RS based on (e.g., according to) the scheduling offset applied at 730 based on the timing of the last PDCCH candidate, and the base station 105-b may transmit it based thereon. For example, the scheduling offset may define an offset between the last symbol of the last PDCCH candidate and the first symbol of the CSI-RS received at 760. In this regard, the UE 115-b may receive the CSI-RS based on transmitting / receiving an RRC message at 705, monitoring PDCCH candidates at 710, transmitting / receiving repetitions of DCI at 715, transmitting / receiving a beam switching threshold at 725, determining a scheduling offset at 730, determining a timing delay at 735, determining an adjusted beam switching threshold at 745, determining a QCL configuration at 750, determining parameters for transmitting / receiving CSI-RS at 755, or any combination thereof, and the base station 105-b may transmit it based thereon.

[0223]

[0232] For example, the UE 115-b may receive the CSI-RS based on the trigger state configuration indicated in the repetition of the DCI received at 715. Similarly, the UE 115-b may receive the CSI-RS based on (e.g., the base station 105-b may transmit it based on) the QCL state determined at 730, which may be based on a comparison of the scheduling offset and a beam switching threshold (or an adjusted beam switching threshold). Additionally, the UE 115-b may receive the CSI-RS based on (e.g., the base station 105-b may transmit it based on) the parameters related to the CSI-RS determined at 735.

[0224]

[0233] Techniques described herein may provide improved scheduling of wireless communications. In particular, by defining signaling, rules, and / or configurations that enable the UE 115-b and base station 105-b to determine the timing of scheduled transmissions (e.g., CSI-RS) via PDCCH repetition, the techniques described herein may enable the UE 115-b and base station 105-b to efficiently determine the timing of scheduled transmissions. Furthermore, by enabling wireless devices to more efficiently determine the timing of scheduled transmissions via PDCCH repetition, the techniques described herein may enable more widespread use of communications using PDCCH repetition within a wireless communications system, thereby improving reliability of wireless communications, improving transmit diversity, and further protecting wireless communications against interference.

[0225]

[0234] 8 illustrates an example of a process flow 800 supporting techniques for timing relationships for repetitions of a PDCCH according to aspects of the disclosure. In some examples, the process flow 800 may implement or be implemented by aspects of the wireless communications system 100, the wireless communications system 200, the resource allocation schemes 300-600, the process flows 700, or any combination thereof. For example, the process flow 800 may illustrate the UE 115-c monitoring a set of PDCCH candidates, receiving one or more repetitions of DCI, applying a scheduling offset based on the last PDCCH candidate, and communicating with the base station 105-c based on the scheduling offset, as described with respect to FIGS. 1-7.

[0226]

[0235] In some cases, the process flow 800 may include a UE 115-c and a base station 105-c, which may be examples of corresponding devices described herein. In particular, the UE 115-c and the base station 105-c shown in FIG. 8 may include examples of the UE 115-a and the base station 105-a shown in FIG.

[0227]

[0236] In some examples, the operations illustrated in process flow 800 may be performed by hardware (including, e.g., circuits, processing blocks, logic components, and other components), code executed by a processor (e.g., software), or any combination thereof. Alternatives to the following may be implemented, with some steps performed in a different order than described, or not performed at all. In some cases, the steps may include additional features not described below, or further steps may be added.

[0228]

[0237] At 805, the UE 115-c may receive an RRC message from the base station 105-c, where the RRC message indicates a scheduling offset for one or more transmissions scheduled via a PDCCH repetition. For example, the RRC message may indicate a scheduling offset (e.g., "SlotOffset") for an SRS scheduled via a DCI repetition (e.g., aperiodic SRS). In some aspects, the scheduling offset (e.g., SlotOffset) associated with an SRS scheduled via a DCI repetition may include an amount of TTIs (e.g., an amount of slots) between a TTI associated with the last PDCCH candidate at which the DCI repetition may be received and a TTI associated with the scheduled SRS. In other words, if the SRS is scheduled via multiple repetitions of DCI received in a set of PDCCH candidates, the SRS may be transmitted by the UE 115-b within an amount of slots of the scheduling offset (e.g., "SlotOffset" amount of slots) after a slot associated with the last PDCCH candidate of the set of PDCCH candidates.

[0229]

[0238] In some aspects, the RRC message may further indicate (e.g., configure) one or more additional parameters associated with the SRS. For example, if the SRS scheduled via PDCCH repetition includes a non-codebook resource set, the RRC message may indicate a non-zero power (NZP) CSI-RS resource identifier. In some aspects, the resource for receiving the CSI-RS associated with the SRS may be located in the same TTI (e.g., the same slot) as the last PDCCH candidate.

[0230]

[0239] At 810, the UE 115-c may receive from the base station 105 an indication of a TTI offset associated with transmission / reception of the CSI-RS. In some aspects, the CSI-RS may be associated with an SRS to be scheduled via DCI repetition, as described in further detail later herein. In some aspects, the indication of the TTI offset (e.g., “SlotOffset-CSI-RS”) may be transmitted / received via an RRC message, a DCI message, a MAC-CE message, or any combination thereof. In this regard, in some cases, the UE 115-b may receive the indication of the TTI offset (e.g., SlotOffset-CSI-RS) via the RRC message received at 805.

[0231]

[0240] At 815, the UE 115-b, the base station 105-b, or both may determine resources (e.g., a set of resources) for transmission / reception of the CSI-RS. In some aspects, the CSI-RS may be associated with an SRS to be scheduled via a repetition of DCI, as described in further detail later herein. In some implementations, the resources for the CSI-RS may be located within the same slot as the last PDCCH candidate in which a repetition of DCI that schedules the associated non-codebook SRS may be received. For example, if the SRS scheduled via a repetition of DCI and / or a CSI-RS associated with the SRS is aperiodic, the UE 115-b and / or the base station 105-b may determine resources within the slot of the last PDCCH candidate that may be used for transmission / reception of the CSI-RS.

[0232]

[0241] Additionally or alternatively, resources for CSI-RS may be located in a slot different from the slot associated with the last PDCCH candidate. In such a case, resources for CSI-RS may be determined based on the TTI offset (e.g., SlotOffset-CSI-RS) determined at 810. For example, if the UE 115-c and / or the base station 105-c determine the TTI offset at 810, the wireless device may be configured to determine resources for CSI-RS transmission / reception based on the TTI associated with the last PDCCH candidate and the TTI offset. In particular, the TTI offset may define an amount of slots after the slot including the last PDCCH candidate in which resources for CSI-RS may be found. In other words, resources for CSI-RS may be found in an amount of "TTI offset" of slots after the slot of the last PDCCH candidate (e.g., an amount of "SlotOffset-CSI-RS" of slots). In this regard, the TTI (e.g., slot) associated with the last PDCCH candidate may be used as a “reference TTI” (e.g., “reference slot”) to determine a slot in which a scheduled SRS may be transmitted, a slot in which a CSI-RS associated with the scheduled SRS may be received, or both.

[0233]

[0242] At 820, the UE 115-c may monitor a set of downlink control channel candidates (e.g., PDCCH candidates) associated with each other. In other words, the UE 115-c may monitor a set of PDCCH candidates linked with each other for PDCCH repetition. In some aspects, the set of PDCCH candidates monitored by the UE 115-c may include at least a first PDCCH candidate in a first TTI (e.g., a first slot) and a last PDCCH candidate in a second TTI (e.g., a second TTI) that is after (e.g., after) the first TTI. In some aspects, the UE 115-c may monitor the set of PDCCH candidates based on receiving an RRC message at 805, receiving a TTI offset at 810, determining resources for CSI-RS at 815, or any combination thereof.

[0234]

[0243] At 825, the UE 115-c may receive one or more repetitions of the DCI from the base station 105-c. The UE 115-c may receive one or more repetitions of the DCI in the first PDCCH candidate, the last PDCCH candidate, or both. In this regard, the UE 115-c may receive one or more repetitions of the DCI based on receiving the RRC message at 805, receiving the TTI offset at 810, determining resources for the CSI-RS at 815, monitoring the set of PDCCH candidates at 820, or any combination thereof. The one or more repetitions of the DCI may include any DCI format that may be received and / or decoded by the UE 115-c, including UE-specific DCI, group-common DCI, or both. For example, the DCI (e.g., DL DCI) may include a format for triggering aperiodic SRS, including DL DCI format 1_1 or 1_2, UL DCI format 0_1 ​​or 0_2, group-common DCI format 2_3, or any combination thereof.

[0235]

[0244] In some aspects, the repetition of the DCI may schedule transmissions between the base station 105-a and the UE 115-a. For example, as shown in FIG. 8, the transmissions scheduled by the repetition of the DCI may include a set of SRSs (e.g., a set of aperiodic SRSs). In some aspects, the repetition of the DCI may indicate a set of resources available by the UE 115-c for transmitting the set of SRSs. For example, an SRS request field in the repetition of the DCI may indicate one or more SRS resource sets for transmitting the set of SRSs. In some cases, one or more repetitions of the DCI (e.g., UL DCI) may include an indication of a trigger state configuration. In some cases, a mapping between the SRS resource sets available for transmission of the set of SRSs and the SRS request code points (e.g., 01, 10, 11) may be provided as part of an RRC parameter (e.g., aperiodicSRS-ResourceTrigger, aperiodicSRSResourceTriggerList) indicated via the RRC message at 805, the repetition of the DCI at 825, or both.

[0236]

[0245] The UE 115-c may receive a CSI-RS from the base station 105-c at 830. In some aspects, the CSI-RS transmitted / received at 830 may be associated with an SRS scheduled by the repetition of the DCI received at 825. The UE 115-c may receive the CSI-RS at 830 based on transmitting / receiving an RRC message at 805, transmitting / receiving a TTI offset at 810, determining resources for the CSI-RS at 815, monitoring PDCCH candidates at 820, transmitting / receiving the repetition of the DCI at 825, or any combination thereof, and the base station 105-c may transmit it based thereon.

[0237]

[0246] For example, the UE 115-c may receive the CSI-RS within the resources for CSI-RS determined at 815. In this regard, in some implementations, the CSI-RS may be received within the same TTI (e.g., the same slot) as the last PDCCH candidate monitored at 820. Additionally or alternatively, if the UE 115-c and / or base station 105-c determine / apply a TTI offset (SlotOffset-CSI-RS), the CSI-RS may be received within some amount of TTIs following the TTI associated with the last PDCCH candidate, where the amount of TTIs is based on the TTI offset.

[0238]

[0247] At 835, the UE 115-c may perform one or more measurements for the CSI-RS received at 830. The UE 115-c may perform the measurements at 835 based on sending / receiving an RRC message at 805, sending / receiving a TTI offset at 810, determining resources for the CSI-RS at 815, monitoring PDCCH candidates at 820, sending / receiving repetitions of DCI at 825, receiving the CSI-RS at 830, or any combination thereof.

[0239]

[0248] At 840, the UE 115-c may determine one or more parameters related to the transmission of the set of SRS scheduled by the repetition of the DCI received at 825. The parameters related to the SRS may include, but are not limited to, a precoder to be used for the transmission of the SRS. In some aspects, the UE 115-c may determine the one or more parameters at 840 based on the one or more measurements performed at 835. For example, the UE 115-c may determine (e.g., calculate) a precoder to be used for the transmission of the set of SRS based on measurements performed on the NZP CSI-RS received at 830.

[0240]

[0249] At 845, the UE 115-c, the base station 105-c, or both may determine and / or apply a scheduling offset associated with a transmission scheduled by a repetition of the DCI. The UE 115-c and / or the base station 105-c may determine / apply the scheduling offset at 845 based on sending / receiving an RRC message at 805, sending / receiving a TTI offset at 810, determining resources for a CSI-RS at 815, monitoring PDCCH candidates at 820, sending / receiving a repetition of the DCI at 825, receiving a CSI-RS at 830, performing measurements at 835, determining parameters for a set of SRS at 840, or any combination thereof.

[0241]

[0250] In some aspects, the UE 115-c and / or the base station 105-c may be configured to apply a scheduling offset regardless of where in the set of PDCCH candidates the repetition of the DCI is detected. In particular, in some cases, the UE 115-c and / or the base station 105-c may be configured to apply a scheduling offset based on the timing of the last PDCCH candidate regardless of where (or how much) in the set of PDCCH candidates the repetition of the DCI is detected. For example, the UE 115-c and / or the base station 105-c may be configured to apply a scheduling offset regardless of whether the first repetition of the DCI is detected in the first PDCCH candidate, whether the second repetition of the DCI is detected in the last PDCCH candidate, or whether both the first and second repetitions of the DCI are detected in the first and last PDCCH candidates, respectively.

[0242]

[0251] In some aspects, the scheduling offset may be based on the timing of the last PDCCH candidate of the set of PDCCH candidates. In particular, the scheduling offset may be based on the placement of the last PDCCH candidate within a TTI, based on a TTI associated with the last PDCCH candidate, or both. For example, if the transmission scheduled by the repetition of the DCI includes a set of SRS, the scheduling offset may include an amount of TTI (e.g., an amount of slots) between the TTI of the last PDCCH candidate and the TTI at which the set of SRS is scheduled (as shown in the scheduling offset 220-b shown in FIG. 2 and the scheduling offset 420 shown in FIG. 4).

[0243]

[0252] At 850, the UE 115-c may transmit a set of SRS scheduled by the repetition of the DCI. The UE 115-c may transmit the set of SRS based on (e.g., according to) the scheduling offset applied at 845 based on the timing of the last PDCCH candidate, and the base station 105-c may receive it based thereon. For example, the UE 115-c may transmit the set of SRS after a scheduling offset (e.g., SlotOffset) applied based on the TTI of the last PDCCH candidate. In other words, the UE 115-c may transmit the set of SRS in slots that are an amount of slots after the slot associated with the last PDCCH candidate, where the amount of slots is based on (e.g., defined by) the scheduling offset (e.g., SlotOffset).

[0244]

[0253] In this regard, the UE 115-c may transmit, and the base station 105-c may receive, the set of SRS based on sending / receiving an RRC message at 805, sending / receiving a TTI offset at 810, determining resources for CSI-RS at 815, monitoring PDCCH candidates at 820, sending / receiving repetitions of DCI at 825, receiving CSI-RS at 830, performing measurements at 835, determining parameters for the set of SRS at 840, determining / applying a scheduling offset at 845, or any combination thereof. For example, the UE 115-c may transmit the set of SRS based on (e.g., in accordance with) one or more parameters determined at 840. For example, if the UE 115-c determines a precoder for the set of SRS at 840, the UE 115-c may transmit the set of SRS at 850 using the determined precoder. Thus, the UE 115-c may transmit the set of SRS based on receiving the CSI-RS associated with the set of SRS at 830.

[0245]

[0254] At 855, the UE 115-c may receive a DCI from the base station 105-c that schedules an uplink transmission (e.g., a PUSCH transmission) from the UE 115-c to the base station 105-c. In particular, the DCI may schedule a non-codebook based PUSCH transmission. In some aspects, the base station 105-c may transmit a DCI (e.g., a UL DCI) based on receiving the set of SRS at 850. In some aspects, the DCI may indicate a set of resources usable by the UE 115-c for transmission of an uplink transmission (e.g., an SRS resource indicator).

[0246]

[0255] At 860, the UE 115-c may transmit an uplink transmission (e.g., a PUSCH transmission) scheduled by the DCI to the base station 105-c. In this regard, the UE 115-c may transmit an uplink transmission (e.g., a PDSCH transmission) message based on receiving the DCI at 855. For example, the UE 115-c may transmit a PDSCH transmission (e.g., a non-codebook based PUSCH transmission) within a set of resources indicated by the DCI (e.g., based on an SRS resource indicator).

[0247]

[0256] Techniques described herein may provide improved scheduling of wireless communications. In particular, by defining signaling, rules, and / or configurations that enable the UE 115-c and base station 105-c to determine the timing of scheduled transmissions (e.g., SRS) via PDCCH repetition, the techniques described herein may enable the UE 115-c and base station 105-c to efficiently determine the timing of scheduled transmissions. Furthermore, by enabling wireless devices to more efficiently determine the timing of scheduled transmissions via PDCCH repetition, the techniques described herein may enable more widespread use of communications using PDCCH repetition within a wireless communications system, thereby improving the reliability of wireless communications, improving transmit diversity, and further protecting wireless communications against interference.

[0248]

[0257] 9 illustrates an example of a process flow 900 supporting techniques for timing relationships for repetitions of a PDCCH according to aspects of the disclosure. In some examples, the process flow 900 may implement or be implemented by aspects of the wireless communications system 100, the wireless communications system 200, the resource allocation schemes 300-600, the process flows 700-800, or any combination thereof. For example, the process flow 900 may illustrate the UE 115-d monitoring a set of PDCCH candidates, receiving one or more repetitions of a DCI, applying a scheduling offset based on the last PDCCH candidate, and communicating with the base station 105-d based on the scheduling offset, as described with respect to FIGS. 1-8.

[0249]

[0258] In some cases, the process flow 900 may include a UE 115-d and a base station 105-d, which may be examples of corresponding devices described herein. In particular, the UE 115-d and the base station 105-d shown in FIG. 9 may include examples of the UE 115-a and the base station 105-a shown in FIG.

[0250]

[0259] In some examples, the operations illustrated in process flow 900 may be performed by hardware (including, e.g., circuits, processing blocks, logic components, and other components), code executed by a processor (e.g., software), or any combination thereof. Alternatives to the following may be implemented, with some steps performed in a different order than described, or not performed at all. In some cases, the steps may include additional features not described below, or further steps may be added.

[0251]

[0260] At 905, the UE 115-d may receive an RRC message from the base station 105-d. In some aspects, the RRC message may indicate one or more minimum scheduling delays (Δ) associated with PDCCH decoding. In some cases, the one or more minimum scheduling delays may be configured in the UE 115-d to avoid excessive buffering of downlink samples due to PDCCH decoding. In particular, the minimum scheduling delay may be configured to allow the UE 115-d sufficient time to process a PDCCH transmission (e.g., a repetition of a DCI) when the PDCCH channel and the PDSCH channel on which the transmission is scheduled have different SCSs. In some aspects, the minimum scheduling delay may define a minimum duration (e.g., a minimum amount of TTI, a minimum amount of slots) between a DCI scheduling a transmission and the start of a transmission scheduled by the DCI.

[0252]

[0261] At 910, the UE 115-d may monitor a set of downlink control channel candidates (e.g., PDCCH candidates) associated with each other. In other words, the UE 115-d may monitor a set of PDCCH candidates linked with each other for PDCCH repetition. In some aspects, the set of PDCCH candidates monitored by the UE 115-d may include at least a first PDCCH candidate in a first TTI (e.g., a first slot) and a last PDCCH candidate in a second TTI (e.g., a second TTI) that is after (e.g., after) the first TTI. In some aspects, the UE 115-d may monitor the set of PDCCH candidates based on receiving an RRC message at 905.

[0253]

[0262] At 915, the UE 115-d may receive one or more repetitions of the DCI from the base station 105-d. The UE 115-d may receive one or more repetitions of the DCI in the first PDCCH candidate, the last PDCCH candidate, or both. In this regard, the UE 115-d may receive one or more repetitions of the DCI based on receiving the RRC message at 905, monitoring the set of PDCCH candidates at 910, or both. The one or more repetitions of the DCI may include any DCI format that may be received and / or decoded by the UE 115-d.

[0254]

[0263] In some aspects, the DCI repetition may schedule transmissions between the base station 105-a and the UE 115-a. For example, as shown in FIG. 9, the DCI message may schedule a PDSCH transmission, a CSI-RS (e.g., aperiodic CSI-RS), or both. In some aspects, the DCI message may indicate a set of resources available by the UE 115-d to receive the PDSCH transmission and / or the CSI-RS. In some cases, the DCI repetition may schedule the PDSCH transmission and / or the CSI-RS in the same or different component carrier (e.g., cross-carrier scheduling) as the control channel (e.g., PDCCH) on which the DCI repetition was received. For example, the PDCCH candidate (and thus the DCI repetition) may be associated with a PDCCH with a first SCS, and the PDSCH transmission and / or the CSI-RS may be scheduled on a different channel (e.g., PDSCH) associated with a second SCS different from the first SCS.

[0255]

[0264] At 920, the UE 115-d, the base station 105-d, or both may determine an SCS associated with a channel on which the repetition of DCI was received, a channel on which the PDSCH transmission and / or CSI-RS is scheduled, or both. The UE 115-d and / or the base station 105-d may determine the SCS at 915 based on monitoring the PDCCH candidates at 905, transmitting / receiving the repetition of DCI at 910, or both.

[0256]

[0265] For example, the UE 115-d and / or the base station 105-d may determine a first SCS associated with a downlink control channel (e.g., a PDCCH) on which at least one repetition of the DCI is received, and may determine a second SCS associated with a channel (e.g., a PDSCH) on which a PDSCH transmission / CSI-RS scheduled by the repetition of the DCI is to be implemented.

[0257]

[0266] At 925, the UE 115-d, the base station 105-d, or both may determine a minimum scheduling delay associated with the scheduled PDCCH transmission and / or CSI-RS. In some aspects, the UE 115-d and / or the base station 105-d may determine the minimum scheduling delay based on transmitting / receiving an RRC message at 905, monitoring PDCCH candidates at 910, transmitting / receiving repetitions of DCI at 915, determining an SCS at 920, or both.

[0258]

[0267] In some aspects, the value of the minimum scheduling delay may be based on the SCS of the control channel (e.g., PDCCH) on which the repetition of the DCI is received. In particular, the minimum scheduling delay may be based on whether the SCS of the PDCCH is shorter (or longer) than the SCS of the channel (e.g., PDSCH) on which the PDSCH transmission and / or CSI-RS is scheduled. In some aspects, the SCS of the PDCCH (μ PDCCH ) SCS, DCI (μ PDSCH, μ CSI-RS ) is shorter than the SCS of the channel associated with the PDSCH / CSI-RS scheduled by the repetition of the PDCCH (μ PDCCH ) SCS is DCI (μ PDSCH , μ CSI-RS ) may not be performed to determine the value of the minimum scheduling delay if the SCS is equal to or greater than the SCS of the channel associated with the PDSCH / CSI-RS scheduled by the repetition of

[0259]

[0268] For example, the minimum scheduling delay (Δ) defined as the amount of symbols associated with the PDCCH (μ PDCCH ) SCS.

[0260] [Table 2]

[0261]

[0269] As an example, the UE 115-d and / or the base station 105-d may determine a first SCS associated with a downlink control channel (e.g., PDCCH) on which at least one repetition of the DCI was received and may determine a second SCS associated with a channel (e.g., PDSCH) on which a PDSCH transmission and / or CSI-RS scheduled by the repetition of the DCI will be implemented. In this example, the UE 115-d and the base station 105-d may determine a minimum scheduling delay based on a comparison of the first SCS and the second SCS. In particular, the UE 115-d and / or the base station 105-d may be configured to perform quantization to determine a minimum scheduling delay based on a comparison of the first SCS and the second SCS.

[0262]

[0270] The UE 115-d, the base station 105-d, or both, determine and / or apply a scheduling offset associated with a transmission scheduled by a repetition of the DCI at 930. The UE 115-d and / or the base station 105-d may determine / apply the scheduling offset at 930 based on transmitting / receiving an RRC message at 905, monitoring PDCCH candidates at 910, transmitting / receiving a repetition of the DCI at 915, determining an SCS at 920, determining a minimum scheduling delay at 925, or any combination thereof.

[0263]

[0271] In some aspects, the UE 115-d and / or the base station 105-d may be configured to apply a scheduling offset regardless of where in the set of PDCCH candidates the repetition of the DCI is detected. In particular, in some cases, the UE 115-d and / or the base station 105-d may be configured to apply a scheduling offset based on the timing of the last PDCCH candidate regardless of where (or how much) in the set of PDCCH candidates the repetition of the DCI is detected. For example, the UE 115-d and / or the base station 105-d may be configured to apply a scheduling offset regardless of whether the first repetition of the DCI is detected in the first PDCCH candidate, whether the second repetition of the DCI is detected in the last PDCCH candidate, or whether both the first and second repetitions of the DCI are detected in the first and last PDCCH candidates, respectively.

[0264]

[0272] In some aspects, the scheduling offset may be based on the timing of the last PDCCH candidate of the set of PDCCH candidates. In particular, the scheduling offset may be based on the placement of the last PDCCH candidate in a TTI, based on the TTI associated with the last PDCCH candidate, or both. In some aspects, the scheduling offset determined / applied at 930 may be based on the minimum scheduling delay determined at 925. For example, in some cases, the scheduling offset may be equal to or greater than the minimum scheduling delay. For example, if the UE 115-d and the base station 105-d determine the minimum scheduling delay to be four slots, the scheduling offset may be determined to be four or more slots.

[0265]

[0273] At 935, the UE 115-d may receive from the base station 105-d a PDSCH transmission and / or a CSI-RS that is scheduled by the repetition of the DCI. The UE 115-d may receive the PDSCH transmission and / or the CSI-RS based on (e.g., in accordance with) the scheduling offset, the minimum scheduling delay, or both, and the base station 105-d may transmit it based thereon.

[0266]

[0274] For example, the UE 115-b may receive, and the base station 105-d may transmit, the PDSCH transmission and / or CSI-RS based on (e.g., according to) the minimum scheduling delay determined at 925 based on the timing of the last PDCCH candidate and / or the scheduling offset determined and applied at 930, where the minimum scheduling delay is less than or equal to the scheduling offset. For example, if the UE 115-d and the base station 105-d determine the minimum scheduling delay to be four slots, the scheduling offset may be determined to be five slots. In this example, the base station 105-d may transmit, and the UE 115-d may receive, the PDSCH transmission and / or CSI-RS in the five slots following the slot associated with the last PDCCH candidate.

[0267]

[0275] Techniques described herein may provide improved scheduling of wireless communications. In particular, by defining signaling, rules, and / or configurations that enable the UE 115-d and base station 105-d to determine the timing of scheduled transmissions (e.g., PDSCH transmissions, CSI-RS) via PDCCH repetitions, the techniques described herein may enable the UE 115-d and base station 105-d to efficiently determine the timing of scheduled transmissions. Furthermore, by enabling wireless devices to more efficiently determine the timing of scheduled transmissions via PDCCH repetitions, the techniques described herein may enable more widespread use of communications using PDCCH repetitions within wireless communications systems, thereby improving reliability of wireless communications, improving transmit diversity, and further protecting wireless communications against interference.

[0268]

[0276] 10 illustrates an example of a process flow 1000 supporting techniques for timing relationships for repetitions of a PDCCH according to aspects of the disclosure. In some examples, the process flow 1000 may implement or be implemented by aspects of the wireless communications system 100, the wireless communications system 200, the resource allocation schemes 300-600, the process flows 800-900, or any combination thereof. For example, the process flow 1000 may illustrate the UE 115-e monitoring a set of PDCCH candidates, receiving one or more repetitions of DCI, applying a scheduling offset based on the last PDCCH candidate, and communicating with the base station 105-e based on the scheduling offset, as described with respect to FIGS. 1-9.

[0269]

[0277] In some cases, the process flow 1000 may include a UE 115-e and a base station 105-e, which may be examples of corresponding devices described herein. In particular, the UE 115-e and the base station 105-e shown in FIG. 10 may include examples of the UE 115-a and the base station 105-a shown in FIG.

[0270]

[0278] In some examples, the operations illustrated in process flow 1000 may be performed by hardware (including, e.g., circuits, processing blocks, logic components, and other components), code executed by a processor (e.g., software), or any combination thereof. Alternatives to the following may be implemented, with some steps being performed in a different order than described, or not performed at all. In some cases, the steps may include additional features not mentioned below, or further steps may be added.

[0271]

[0279] At 1005, the UE 115-e may receive an RRC message from the base station 105-e. In some aspects, the RRC message may indicate one or more minimum scheduling offsets associated with a transmission scheduled by the base station. In some cases, the one or more minimum scheduling offsets may be configured at the UE 115-e to avoid excessive buffering of downlink samples due to PDCCH decoding and to enable the UE 115-e to perform any beam switching or realignment procedures required to perform the scheduled transmission. The minimum scheduling offsets may further be used to reduce power consumption at the UE 115-e and the base station 105-e. In some cases, the minimum scheduling offsets may include one or more K0 values ​​(e.g., minK0) associated with a scheduled PDSCH transmission, one or more K2 values ​​(e.g., minK2) associated with a scheduled PUSCH transmission, or both. For example, in some cases, the UE 115-e may be configured with up to two values ​​for each of the minK0 and minK2 parameters. In some aspects, the minimum scheduling offset may define a minimum duration (eg, a minimum amount of TTIs, a minimum amount of slots) between a DCI scheduling a transmission and the start of a transmission scheduled by the DCI.

[0272]

[0280] At 1010, the UE 115-e may monitor a set of downlink control channel candidates (e.g., PDCCH candidates) associated with each other. In other words, the UE 115-e may monitor a set of PDCCH candidates linked with each other for PDCCH repetition. In some aspects, the set of PDCCH candidates monitored by the UE 115-e may include at least a first PDCCH candidate in a first TTI (e.g., a first slot) and a last PDCCH candidate in a second TTI (e.g., a second TTI) that is after (e.g., after) the first TTI. In some aspects, the UE 115-e may monitor the set of PDCCH candidates based on receiving an RRC message at 1005.

[0273]

[0281] At 1015, the UE 115-e may receive one or more repetitions of the DCI from the base station 105-e. The UE 115-e may receive the one or more repetitions of the DCI in the first PDCCH candidate, the last PDCCH candidate, or both. In this regard, the UE 115-e may receive the one or more repetitions of the DCI based on receiving the RRC message at 1005, monitoring the set of PDCCH candidates at 1010, or both. The one or more repetitions of the DCI may include any DCI format (e.g., DCI formats 0_1, 1_1) that may be received and / or decoded by the UE 115-e.

[0274]

[0282] In some aspects, the repetition of the DCI may schedule transmissions between the base station 105-a and the UE 115-a. For example, as shown in FIG. 10, the DCI message may schedule a PDSCH transmission, a PDSCH transmission, or both. In some aspects, the DCI message may indicate a set of resources usable by the UE 115-e to receive a PDSCH transmission and / or a PUSCH transmission.

[0275]

[0283] In some aspects, the repetition of the DCI may include one or more bit fields indicating which minimum scheduling offset is to be applied (e.g., which minimum scheduling offset is active). For example, if the repetition of the DCI schedules a PDSCH transmission and the UE 115-e is configured with two minK0 values ​​for the PDSCH transmission, the repetition of the DCI may indicate which minK0 value is to be applied when performing the scheduled PDSCH transmission.

[0276]

[0284] Additionally or alternatively, the repetition of the DCI may indicate a change in one or more values ​​of the minimum scheduling offset. In particular, the repetition of the DCI may indicate a change in one or more values ​​of the minimum scheduling offset indicator field of the repetition of the DCI. For example, if the UE 115-e is configured with a first minK0 value and a second minK0 value for PDSCH transmission, the repetition of the DCI may indicate a change to the first minK0 value. In other words, the repetition of the DCI may indicate an adjusted minimum scheduling offset (e.g., adjusted minK0 value, adjusted minK2 value) for the PDSCH / PDSCH transmission that is different from the original minimum scheduling offset (e.g., original minK0 value, minK2 value). In some cases, the indication of the change in the minimum scheduling offset may also indicate the activation of the respective changed minimum scheduling offset. For example, continuing with the above example, if the repetition of the DCI indicates a change to the first minK0 value, the change to the first minK0 value may also serve as a selection of the adjusted (changed) first minK0 value.

[0277]

[0285] If the repetition of the DCI indicates a change in the minimum scheduling offset, the repetition of the DCI may further indicate a scheduling offset (e.g., an application delay). In some aspects, the scheduling offset (e.g., an application delay) may indicate when a change to the minimum scheduling offset is to be applied (e.g., when a change to the minK0 and / or minK2 values). In some aspects, the scheduling offset / application delay may define an amount of slots, an amount of symbols, and / or an amount of TTIs relative to the last symbol of the second slot that includes the last PDCCH candidate 610-b.

[0278]

[0286] At 1020, the UE 115-e, the base station 105-e, or both may determine a change to one or more values ​​of the minimum scheduling offset. The UE 115-e and the base station 105-e may determine a change to the one or more minimum scheduling offsets based on an indication of the change received via a repetition of the DCI received at 1020 (e.g., via one or more minimum scheduling offset indicator fields of the DCI).

[0279]

[0287] At 1025, the UE 115-e, the base station 105-e, or both, determine and / or apply a scheduling offset / application delay indicated via the repetition of the DCI. In particular, the UE 115-e and / or the base station 105-e may determine that a change in one or more values ​​of the minimum scheduling offset is to be applied after the scheduling offset / application delay applied based on the timing of the last PDCCH candidate. The UE 115-e and / or the base station 105-e may determine / apply the minimum scheduling offset at 1020 based on sending / receiving an RRC message at 1005, monitoring PDCCH candidates at 1010, sending / receiving repetitions of the DCI at 1015, determining a change in the minimum scheduling offset at 1020, or any combination thereof.

[0280]

[0288] In some aspects, the UE 115-e and / or the base station 105-e may be configured to apply a scheduling offset / application delay regardless of where in the set of PDCCH candidates the repetition of the DCI is detected (e.g., apply one or more changes to the minimum scheduling offset based on the scheduling offset / application delay). In particular, in some cases, the UE 115-e and / or the base station 105-e may be configured to apply a scheduling offset / application delay based on the timing of the last PDCCH candidate regardless of where (or how much) in the set of PDCCH candidates the repetition of the DCI is detected. For example, the UE 115-e and / or the base station 105-e may be configured to apply a scheduling offset / application delay regardless of whether the first repetition of the DCI is detected in the first PDCCH candidate, whether the second repetition of the DCI is detected in the last PDCCH candidate, or whether both the first and second repetitions of the DCI are detected in the first and last PDCCH candidates, respectively.

[0281]

[0289] In some aspects, the scheduling offset / application delay may be based on the timing of the last PDCCH candidate in the set of PDCCH candidates. In particular, the scheduling offset / application delay may be based on the placement of the last PDCCH candidate within a TTI, based on a TTI associated with the last PDCCH candidate, or both. For example, the scheduling offset / application delay may define an amount of slots between slots associated with the last PDCCH candidate. In some aspects, by applying the scheduling offset / application delay, the UE 115-e and / or the base station 105-e may be configured to apply a change to the minimum scheduling offset (e.g., apply a change to the minK2 value, the minK0 value) following the end of the scheduling offset / application delay.

[0282]

[0290] At 1030, the UE 115-e and / or the base station 105-e may implement the changes to the minimum scheduling offset determined at 1020. In some aspects, the UE 115-e and the base station 105-e may implement the changes to the minimum scheduling offset based on the application of a scheduling offset / applied delay. In particular, the UE 115-e and / or the base station 105-e may be configured to implement the changes to the minimum scheduling offset after the end of the applied scheduling offset / applied delay based on the timing of the last PDCCH candidate (e.g., based on the last symbol of the slot including the last PDCCH candidate).

[0283]

[0291] In this regard, which minK0 value and / or minK0 value (e.g., which minimum scheduling offset) is applied to each PDSCH / PUSCH transmission may be based on the scheduling offset / application delay. If a PDSCH / PUSCH transmission is scheduled via DCI received before the end of the scheduling offset / application delay, the old (e.g., unmodified) minimum scheduling offset is applied (e.g., unmodified minK2 value, minK0 value). Conversely, if a PDSCH / PUSCH transmission is scheduled via DCI received after the end of the scheduling offset / application delay, the new modified (e.g., adjusted) minimum scheduling offset is applied (e.g., adjusted minK2 value, adjusted minK0 value).

[0284]

[0292] At 1035, the UE 115-e may receive DCI from the base station 105-e, where the DCI schedules a PDSCH and / or PUSCH transmission. In some aspects, the UE 115-e may receive DCI that schedules a PDSCH and / or PUSCH transmission following the end of the scheduling offset / application delay (and thus after a change to the minimum scheduling offset has been implemented).

[0285]

[0293] At 1040, the UE 115-e may receive from the base station 105-e a PDSCH transmission that is scheduled by the DCI received at 1035. The UE 115-e may receive and the base station 105-e may transmit the PDSCH transmission based on the scheduling offset / applied delay at 1025, modifying the minimum scheduling offset at 1030, or both. For example, the UE 115-e may receive the PDSCH transmission at 1040 in accordance with the adjusted minimum scheduling offset implemented at 1030 based on the application of the scheduling offset / applied delay.

[0286]

[0294] At 1045, the UE 115-e may transmit to the base station 105-e a PUSCH transmission scheduled by the DCI received at 1030. The UE 115-e may transmit, and the base station 105-e may receive, a PUSCH transmission based on the scheduling offset / applied delay at 1025, modifying the minimum scheduling offset at 1030, or both. For example, the UE 115-e may transmit a PUSCH transmission at 1045 in accordance with the adjusted minimum scheduling offset implemented at 1030 based on the application of the scheduling offset / applied delay.

[0287]

[0295] The techniques described herein may provide improved scheduling of wireless communications. In particular, by defining signaling, rules, and / or configurations that enable the UE 115-e and the base station 105-e to determine the timing of scheduled transmissions (e.g., PDSCH transmissions, PUSCH transmissions) via PDCCH repetitions, the techniques described herein may enable the UE 115-e and the base station 105-e to efficiently determine the timing of scheduled transmissions. Furthermore, by enabling wireless devices to more efficiently determine the timing of scheduled transmissions via PDCCH repetitions, the techniques described herein may enable more widespread use of communications using PDCCH repetitions within wireless communications systems, thereby improving reliability of wireless communications, improving transmit diversity, and further protecting wireless communications against interference.

[0296] 11 illustrates a block diagram 1100 of a device 1105 supporting techniques for timing relationships for repetitions of a PDCCH according to an aspect of the disclosure. The device 1105 may be an example of an aspect of a UE 115 described herein. The device 1105 may include a receiver 1110, a transmitter 1115, and a communications manager 1120.

[0301] Additionally or alternatively, in some examples, the communications manager 1120, the receiver 1110, the transmitter 1115, or various combinations or components thereof may be implemented in code executed by a processor (e.g., as communications management software). When implemented in code executed by a processor, the functionality of the communications manager 1120, the receiver 1110, the transmitter 1115, or various combinations or components thereof may be performed by a general-purpose processor (e.g., configured as or otherwise supporting a means for performing the functions described in this disclosure), a DSP, a central processing unit (CPU), a graphics processing unit (GPU), an ASIC, an FPGA, or any combination thereof or other programmable logic device.

[0294]
