[0056] In a wireless communication system, resources for various channels and signals that a user equipment (UE) will use for communications may be allocated by a base station. Due to processing complexity, interference and other considerations, the positioning of these resources relative to other resources can affect communication reliability and efficiency. In some cases, the base station may configure the UE with resources for a physical downlink shared channel (PDSCH) with a specific resource mapping type (eg, mapping type A). Due to various considerations, scheduling a PDSCH in the same slot of a physical downlink control channel (PDCCH) may result in scheduling the PDSCH with Type A mapping if that PDCCH is not received within any threshold number of symbols in that slot. It is not expected to be scheduled. That is, when the scheduling PDCCH is included within the first three symbols of a slot, the PDSCH with type A mapping can be scheduled in the same slot of the scheduling PDCCH.

[0057] Another resource consideration scenario concerns channel state information (CSI) reference signal resources. A downlink control information (DCI) message can trigger CSI reporting over a physical uplink shared channel (PUSCH). Based on the CSI request field of the DCI, the UE can identify CSI-RS resources that the UE will measure for CSI reporting. Due to various considerations, the UE may not expect the aperiodic CSI-RS to be transmitted prior to the symbols carrying the triggering DCI (e.g., the DCI containing the CSI report request). More specifically, the UE expects the CSI-RS resources to be positioned during or after the first symbol carrying the DCI that triggers measurement of the CSI-RS resources.

[0058] Some wireless communication systems may support PDCCH repetition to improve communication reliability and efficiencies. That is, by repeating PDCCH transmissions, the receiving UE has a high probability of successfully decoding the PDCCH and can therefore identify various control information, including scheduling information for other channels. In some cases, the UE may decode one of the PDCCH candidates. In these cases, the network or base station may not be configured with information to identify candidates that the UE was able to decode. In these cases, the applicability of resource configuration considerations may be unclear.

[0059] Implementations described herein provide techniques for applying confirmation rules when repetitive (and linked) PDCCHs are configured. In some examples, the UE may decode the DCI from one or both of the (linked) first and second PDCCH candidates, and the DCI may schedule resources for the PDSCH. The UE may apply a rule to check whether at least one of the first PDCCH candidate or the second PDCCH candidate is within a threshold number of symbols at the beginning of a transmission time interval (eg, slot) in which PDSCH resources are scheduled. In some cases, the UE may consider whether candidates are positioned between or within slots to determine which confirmation rule to apply.

[0060] In some examples, the UE may decode the DCI from one or both of the (linked) first and second PDCCH candidates, and the DCI may include a CSI request. The UE may apply a rule to ensure that the reference signal resources associated with the CSI request are positioned at least after the start symbol of the first PDCCH candidate. In some cases, the UE may confirm that the reference signal resources are positioned after the start symbol of both the first and second PDCCH candidates. These and other implementations are further described herein with respect to the following figures.

[0061] Aspects of the disclosure are initially described in the context of wireless communication systems. Aspects of the disclosure are further described with respect to a wireless communication system, various resource diagrams, and process flow diagrams. Aspects of the present disclosure are further illustrated and described with reference to device diagrams, system diagrams, and flow diagrams related to identifying resources associated with repetition-based linked downlink control channel candidates.

[0062] FIG. 1 illustrates an example of a wireless communication system 100 that supports identifying resources associated with repetition-based linked downlink control channel candidates, in accordance with aspects of the present disclosure. 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, wireless communication system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, wireless communication system 100 may utilize enhanced broadband communications, ultra-reliable (e.g., mission critical) communications, low-latency communications, or low-cost and low-complexity devices. communications, or any combination thereof.

[0063] Base stations 105 may be distributed throughout a geographic area to form the wireless communication system 100 and may be of different types or devices with different capabilities. Base stations 105 and UEs 115 may communicate wirelessly via one or more communication links 125 . Each base station 105 may provide a coverage area 110 over which UEs 115 and the base station 105 may establish one or more communication links 125 . According to one or more radio access technologies, coverage area 110 may be an example of a geographic area in which base station 105 and UE 115 can support communication of signals.

[0064] UEs 115 may be distributed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary, mobile, or both at different times. You can. UEs 115 may be devices of different types or with different capabilities. Some example UEs 115 are illustrated in FIG. 1 . UEs 115 described herein may be connected to various types of devices, such as other UEs 115, base stations 105, or network equipment (e.g., core network nodes, It may be possible to communicate with relay devices, integrated access and backhaul (IAB) nodes, or other network equipment.

[0065] The base stations 105 may communicate with the core network 130, with each other, or both. For example, base stations 105 may interface with core network 130 via one or more backhaul links 120 (eg, via S1, N2, N3 or other interface). Base stations 105 may interact with each other directly (e.g., directly between base stations 105) or indirectly (e.g., through the core network) via backhaul links 120 (e.g., via X2, (130)) or both. In some examples, backhaul links 120 may be or include one or more wireless links.

UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 includes or includes a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples. may be referred to as, and they may be implemented in various objects, such as devices, or vehicles, or meters.

[0068] The UEs 115 described herein may include, as shown in Figure 1, network equipment and It may be possible to communicate with various types of devices, such as base stations 105 as well as other UEs 115 which may sometimes act as repeaters.

[0069] UEs 115 and base stations 105 may wirelessly communicate with each other via one or more communication links 125 using one or more carriers. The term “carrier” may refer to a set of radio frequency spectrum resources with a defined physical hierarchy to support communication links 125. For example, the carrier used for communication link 125 may be a radio frequency spectrum band operating along one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). It may include a part (eg, a bandwidth part (BWP)). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling that coordinates operation on 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. UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers depending on the carrier aggregation configuration. Carrier aggregation may be used for both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers.

[0070] In some examples (eg, in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling that coordinates operations for other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal mobile telecommunication system terrestrial radio access (E-UTRA) absolute radio frequency channel number (EARFCN) and may be associated with a channel raster for discovery by UEs 115. The carrier may be operated in a standalone mode where the initial acquisition and connection may be performed by UEs 115 over the carrier, or the carrier may be positioned according to the carrier (e.g., using the same or a different radio access technology). ) can be operated in a non-standalone mode anchored using a different carrier.

[0071] Communication links 125 shown in wireless communication system 100 include uplink transmissions from UE 115 to base station 105 or downlink transmissions from base station 105 to UE 115. can do. The carriers may carry downlink or uplink communications (eg, in FDD mode) or may be configured to carry downlink and uplink communications (eg, in TDD mode).

[0072] 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 a carrier or “system bandwidth” of wireless communication system 100. For example, the carrier bandwidth may be one of a number of determined bandwidths (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz) for the carriers of a particular radio access technology. Devices (e.g., base stations 105, UEs 115, or both) of wireless communication system 100 may have hardware configurations that support communications over a specific carrier bandwidth, or a set of carrier bandwidths. It may be configurable to support communications over one of the carrier bandwidths. In some examples, wireless communication system 100 may include base stations 105 or UEs 115 that support simultaneous communications on carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on portions (eg, subband, BWP) or all of the carrier bandwidth.

[0073] The signal waveforms transmitted on the carrier may be multiple (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM). It may be composed of subcarriers. In a system utilizing 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 subcarrier spacing are inversely related. 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). Accordingly, the more resource elements the UE 115 receives and the higher the order of the modulation scheme, the higher the data rate for the UE 115 can 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 can be used to determine the data rate or Data integrity can be further increased.

[0074] One or more numerologies for a carrier may be supported, where the numerology may include a subcarrier spacing (?f) and a cyclic prefix. The carrier may be divided into one or more BWPs with the same or different numerologies. In some examples, 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 communications for UE 115 may be limited to one or more active BWPs.

[0075] Time intervals for base stations 105 or UEs 115, e.g. May be expressed as multiples of the base time unit, which can refer to a sampling period of seconds, where: may indicate the maximum subcarrier spacing supported, and may indicate the maximum supported DFT (discrete Fourier Transform) size. Time intervals of the communication resource may be organized into radio frames each having a specific duration (eg, 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (eg, ranging from 0 to 1023).

[0076] Each frame may include a number of consecutively numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into multiple slots. Alternatively, each frame may include a variable number of slots, with the number of slots depending on the subcarrier spacing. Each slot may include a number of symbol periods (eg, depending on the length of the cyclic prefix attached to each symbol period). In some wireless communication systems 100, a slot may be further divided into multiple mini-slots containing one or more symbols. Excluding cyclic prefixes, each symbol period can be one or more (e.g. ) may include sampling periods. The duration of the symbol period may depend on the frequency band or subcarrier spacing of operation.

[0077] A subframe, slot, mini-slot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (i.e., the number of symbol periods of the TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of wireless communication system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0078] Physical channels may be multiplexed on a carrier according to various techniques. The physical control channel and physical data channel may be multiplexed on the downlink carrier using, for example, one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control zone (e.g., control resource set (CORESET)) for a physical control channel may be defined by a number of symbol periods and may extend over the system bandwidth or a subset of the carrier's system bandwidth. One or more control zones (eg, CORESETs) may be configured for a set of UEs 115. For example, one or more of the UEs 115 may monitor or search control areas for control information according to one or more search space sets, each search space set arranged in a cascaded manner. It may include one or multiple control channel candidates at one or more aggregation levels. The aggregation level for a control channel candidate may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with encoded information for a control information format with a given payload size. The search space sets may include common search space sets configured to transmit control information to multiple UEs 115 and UE-specific search space sets configured to transmit control information to a specific UE 115 .

[0079] Each base station 105 may provide communication coverage over one or more cells, such as a macro cell, small cell, hot spot, or other types of cells, or any combination thereof. The term “cell” may refer to a logical communication entity used to communicate with base station 105 (e.g., via a carrier) and may include an identifier (e.g., physical cell identifier (PCID), VCID) to distinguish neighboring cells. (virtual cell identifier), etc.). In some examples, a cell may also refer to geographic coverage area 110 or a portion (eg, sector) of geographic coverage area 110 in which a logical communication entity operates. Such cells may range from smaller areas (e.g., a structure, a subset of the structure) to larger areas 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 external spaces between or overlapping geographic coverage areas 110, among other examples.

[0080] A macro cell typically covers a relatively large geographic area (e.g., several kilometers in radius) and can allow unrestricted access by UEs 115 with a service subscription to a network provider that supports the macro cell. there is. A small cell may be associated with a base station 105 of lower power compared to a macro cell, and the small cell may operate in the same or different (eg, licensed, unlicensed) frequency bands as the macro cells. Small cells can provide unrestricted access to UEs 115 with a service subscription to a network provider or UEs 115 associated with a small cell (e.g., UEs 115 within a closed subscriber group (CSG)). ), may provide restricted access to UEs 115) associated with users at home or in the office. Base station 105 may support one or multiple cells and may also support communications over one or more cells using one or multiple component carriers.

[0081] In some examples, a carrier may support multiple cells, and different cells may support different protocol types (e.g., MTC, narrowband IoT (NB-IoT), It can be configured according to enhanced mobile broadband (eMBB).

[0082] In some examples, base station 105 may be mobile and thus may provide communications coverage for a mobile geographic coverage area 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 a heterogeneous network, e.g., where different types of base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies. You can.

[0083] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, base stations 105 may have similar frame timings and transmissions from different base stations 105 may be approximately aligned in time. For asynchronous operation, base stations 105 may have different frame timings, and transmissions from different base stations 105 may not be aligned in time in some examples. The techniques described herein can be used for synchronous or asynchronous operations.

[0084] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices, but may provide automated communication between machines (e.g., via Machine-to-Machine (M2M) communication). You can. M2M communications, 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 communications or MTC may include communications from devices that integrate sensors or meters to measure or capture information and relay that information to a central server or application program. presents information to people who use it or interact with the application program. Some UEs 115 may be designed to collect information or enable automated behavior of machines or other devices. 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, and fleet management. ) and tracking, remote security detection, physical access control, and transaction-based business charging.

[0085] Some UEs 115 operate to reduce power consumption, such as half-duplex communications (e.g., a mode that supports unidirectional communication through transmission or reception, but does not support transmission and reception simultaneously) Can be configured to use modes. In some examples, half-duplex communications may be performed at a reduced peak rate. Other power saving techniques for UEs 115 include entering a power saving deep sleep mode when not engaging in active communications, operating in limited bandwidth (e.g., depending on narrowband communications), or a combination of these techniques. For example, some UEs 115 use a narrowband protocol type associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within the carrier, within the guard-band of the carrier, or outside the carrier. It can be configured for operation.

[0086] The wireless communication system 100 may be configured to support ultra-reliable communications or low-latency communications or various combinations thereof. For example, wireless communication system 100 may be configured to support ultra-reliable low-latency communications (URLLC) or mission-critical communications. UEs 115 may be designed to support ultra-reliable, low-latency, or critical functions (eg, mission-critical functions). Ultra-reliable communications may include private or group communications and are 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). It can be. Support for mission-critical functions may include prioritization of services, and 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.

[0087] In some examples, UE 115 also communicates with other UEs (e.g., using a peer-to-peer (P2P) or device-to-device (D2D) protocol) via a D2D communication link 135. It may be possible to communicate directly with 115). One or more UEs 115 utilizing D2D communications may be within the geographic coverage area 110 of base stations 105 . Other UEs 115 in this group may be outside the geographic coverage area 110 of base station 105 or may otherwise not receive transmissions from base station 105 . In some examples, groups of UEs 115 communicating via D2D communications may utilize a one-to-many (1:M) system, where each UE 115 is connected to a group Transmit to every other UE 115 within. In some examples, base station 105 facilitates scheduling of resources for D2D communications. In other cases, D2D communications are performed between UEs 115 without the involvement of a base station 105.

[0088] In some systems, D2D communication link 135 may be an example of a communication channel, such as a sidelink communication channel between vehicles (e.g., UEs 115). In some examples, vehicles may communicate using vehicle-to-everything (V2X) communications, vehicle-to-vehicle (V2V) communications, or some combination thereof. The vehicle may signal information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure, such as roadside units, or one or more network nodes (e.g., base stations 105) using vehicle-to-network (V2N) communications. It can communicate with the network via , or both.

[0089] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which includes at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility entity (AMF)) that manages access and mobility. management function) and at least one configured to route packets or interconnect to external networks (e.g., a serving gateway (S-GW), a Packet Data Network (PDN) gateway (P-GW), or a user plane function (UPF)). Can contain one user plane entity. The control plane entity manages non-access stratum (NAS) functions such as mobility, authentication, and bearer management for UEs 115 served by base stations 105 associated with the core network 130. can do. User IP packets may be transmitted through a user plane entity that may provide IP address assignment as well as other functions. A user plane entity may be connected to IP services 150 for one or more network operators. IP services 150 may include access to the Internet, intranet(s), IP Multimedia Subsystem (IMS), or Packet-Switched (PS) streaming service.

[0090] Some of the network devices, such as base station 105, may include subcomponents such as access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 communicates with UEs 115 via one or more other access network transmitting entities 145, which may be referred to as radio heads, smart radio heads or transmission/reception points (TRPs). Can communicate. Each access network transmitting entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 are distributed across various network devices (e.g., radio heads and ANCs) or are distributed across a single network device (e.g., base station 105 )) can be integrated into.

[0091] The wireless communication system 100 may operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately 1 decimeter to 1 meter in length. UHF waves may be blocked or redirected by buildings and environmental features, but the waves may penetrate structures sufficiently for a macro cell to serve UEs 115 located indoors. Transmission of UHF waves requires smaller antennas and shorter distances (e.g., less than 100 kilometers).

[0092] The wireless communication system 100 may also operate in the super high frequency (SHF) region using the frequency bands of 3 GHz to 30 GHz, also known as the centimeter band, or in the extremely high frequency (EHF) region of the spectrum, also known as the millimeter band (e.g. , can operate at 30GHz to 300GHz). In some examples, wireless communication system 100 may support millimeter wave (mmW) communications between UEs 115 and base stations 105, with the EHF antennas of individual devices being smaller and closer together than UHF antennas. can be spaced apart. In some examples, this may facilitate the use of antenna arrays within a device. However, the propagation of EHF transmissions suffers much greater atmospheric attenuation than SHF or UHF transmissions and can travel shorter distances. The techniques disclosed herein may be used across transmissions using one or more different frequency zones, and the designated use of bands across such frequency zones may vary by country or regulatory agency.

[0093] The wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may use LTE License 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. You can. When operating in unlicensed radio frequency spectrum bands, devices such as base stations 105 and UEs 115 may utilize carrier sensing for collision detection and avoidance. In some examples, operations in unlicensed bands may be based on a carrier aggregation configuration (eg, LAA) with component carriers operating in licensed bands. Operations in unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.

[0094] The base station 105 or UE 115 may be equipped with multiple antennas, which utilize techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. It can be used to do this. The antennas of base station 105 or UE 115 may be located within 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 base station 105 may be located at various geographic locations. Base station 105 may have an antenna array with multiple rows and columns of antenna ports that base station 105 can use to support beamforming of communications with UE 115. . Similarly, UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted through the antenna ports.

[0095] Base stations 105 or UEs 115 may use MIMO communications to increase spectral efficiency by utilizing multipath signal propagation and transmitting or receiving multiple signals over different spatial layers. These techniques may be referred to as spatial multiplexing. Multiple signals may be transmitted by the transmitting device, for example, via different antennas or different combinations of antennas. Similarly, multiple signals may be received by the 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 measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO), where multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO), where multiple spatial layers are transmitted to multiple devices.

[0096] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is used at a transmitting device or a receiving device (e.g., base station 105, UE 115) to form a spatial path between the transmitting device and the receiving device. It is a signal processing technology that can shape or steer an antenna beam (e.g., a transmission beam or a reception beam) along the . Beamforming may be achieved by combining signals communicated via antenna elements of an antenna array such that some signals propagating at specific orientations with respect to the antenna array experience constructive interference while other signals experience destructive interference. Adjustment of signals communicated via antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a set of beamforming weights associated with a particular orientation (eg, for an antenna array of a transmitting device or a receiving device, or for some other orientation).

[0097] The base station 105 or UE 115 may use beam sweeping techniques as part of beam forming operations. For example, base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communications with UE 115. Some signals (eg, synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted by base station 105 multiple times in different directions. For example, base station 105 may transmit a signal according to different beamforming weight sets associated with different transmission directions. Transmissions in different beam directions identify the beam direction for subsequent transmission or reception by base station 105 (e.g., by a transmitting device, such as base station 105, or by a receiving device, such as UE 115). can be used to

[0098] Some signals, such as data signals associated with a particular receiving device, may be transmitted by base station 105 in a single beam direction (e.g., the direction associated with the receiving device, such as UE 115). In some examples, the beam direction associated with transmissions along a single beam direction can be determined based on a signal transmitted in one or more beam directions. For example, UE 115 may receive one or more of the signals transmitted by base station 105 in different directions, and may select one or more of the signals that UE 115 received with the highest or otherwise acceptable signal quality. The indication may be reported to base station 105.

[0099] In some examples, transmissions by a device (e.g., by base station 105 or UE 115) may be performed using multiple beam directions, with the device (e.g., by base station 105) A combination of digital precoding or radio frequency beamforming may be used to generate a combined beam for transmission (to UE 115). UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a system bandwidth or a configured number of beams across one or more subbands. The base station 105 may transmit a reference signal (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)) that may or may not be precoded. 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 are described with reference to signals transmitted in one or more directions by base station 105, UE 115 may be used to identify a beam direction (e.g., to identify a beam direction for subsequent transmission or reception by UE 115). Similar techniques can be used to transmit signals multiple times in different directions or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0100] A receiving device (e.g., UE 115) may use a number of receiving configurations when receiving various signals, such as synchronization signals, reference signals, beam selection signals, or other control signals, from base station 105. (For example, you can try directional listening). For example, the receiving device receives via different antenna subarrays, processes received signals according to different antenna subarrays, and sets different receive beamforming weights applied to signals received at a plurality of antenna elements of the antenna array ( Multiple receive directions, e.g., receiving according to different directional listening weight sets), or processing received signals according to different receive beamforming weight sets applied to the received signals at multiple antenna elements of the antenna array. may be attempted, any of which may be referred to as “listening” according to different reception configurations or reception directions. In some examples, a 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 have a beam direction determined based on listening along different receiving configuration directions (e.g., based on listening along multiple beam directions, highest signal strength, highest signal-to-noise ratio (SNR), or Otherwise, it can be aligned in a beam direction determined to have acceptable signal quality.

[0101] The wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or Packet Data Convergence Protocol (PDCP) layer may be IP-based. The Radio Link Control (RLC) layer can perform packet segmentation and reassembly for communication through logical channels. The MAC (Medium Access Control) layer can perform multiplexing and priority handling of logical channels into transmission channels. The MAC layer may also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer, to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer establishes, configures and maintains the RRC connection between the core network 130 or base station 105 and UE 115 supporting radio bearers for user plane data. can be provided. At the physical layer, transport channels can be mapped to physical channels.

[0102] UEs 115 and base stations 105 may support retransmissions of data to increase the likelihood that data is successfully received. Hybrid automatic repeat request (HARQ) feedback is one technique to increase the likelihood that data is accurately received over communication link 125. HARQ may include a combination of error detection (e.g., using cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ can improve the throughput of the MAC layer in poor radio conditions (eg, 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 of the slot. In other cases, the device may provide HARQ feedback in a subsequent slot or according to some other time interval.

[0103] The wireless communication system 100 may support channel repetition to increase communication reliability. For example, the base station 105 may repeat PDCCH transmissions to increase the likelihood that the receiving UE 115 will decode the DCI of the PDCCH to identify control and scheduling information. However, in such cases, the network (base station 105) may not be able to identify a candidate for which the DCI is to be decoded by UE 115. Accordingly, resource location considerations may be difficult to apply by UE 115 and base station 105.

[0104] Implementations described herein support confirmation rules that the UE 115 and/or base station 105 can apply to PDCCH repetition scenarios. For example, if the UE 115 is configured to monitor PDCCH repetitions, the UE 115 may monitor one or more when a DCI included in one of the repetitions schedules a PDSCH (e.g., type A) or triggers a CSI report. Rules can be applied. In the case of PDSCH Type A scheduling, the UE 115 decodes the DCI in one or both of the first PDCCH candidate and the second PDCCH candidate and selects the first PDCCH candidate at the beginning of the transmission time interval in which resources for the PDSCH are scheduled. Alternatively, a rule may be applied to determine that at least one of the second PDCCH candidates is within a threshold number of symbols. UE 115 may receive downlink messages on PDSCH resources based on application of rules. In some examples, UE 115 may consider whether the first and second PDCCH repetitions are inter-slot or intra-slot and apply a rule based on the decision.

[0105] In the case of a CSI-RS report triggered by a DCI of a linked PDCCH candidate, the UE 115 sends a DCI (including a CSI request) in one or both of the first PDCCH candidate and the second PDCCH candidate. Rules may be applied to decode and determine that the reference signal resources associated with the CSI request are positioned at least after the start symbol of the first PDCCH candidate (eg, the earliest candidate). UE 115 may transmit CSI reports based on application of rules. In some cases, UE 115 may determine that the reference signal resources are positioned after the start symbol of both the first and second PDCCH candidates.

[0106] Accordingly, using these rules, UE 115 may determine that the position of various resources may not cause additional complexity considerations, interference, or some other error condition. Additionally, the base station 105 may determine that these rules are confirmed when scheduling various resources, such as CSI-RS resources and PDSCH resources. Therefore, application of these rules can improve communication reliability and efficiency, among other benefits.

[0107] Figure 2 illustrates an example of a wireless communication system 200 that supports identifying resources associated with repetition-based linked downlink control channel candidates, in accordance with aspects of the present disclosure. Wireless communication system 200 may implement aspects of wireless communication system 100 . For example, wireless communication system 200 includes base station 105-a and UE 115-a, which may be examples of the corresponding devices of FIG. 1. Figure 2 illustrates examples of communications 205 between base station 105-a and UE 115-a.

[0108] As illustrated by communications 205-a, wireless communication system 200 may support base station 105-a transmitting control information on PDCCH 210 scheduling PDSCH 215. there is. In some cases, control information (e.g., DCI) may trigger PDSCH 215 with Type A mapping, as illustrated in communication 205-a. According to Type A PDSCH mapping, the first demodulation reference signal (DMRS) 215 symbol of the PDSCH 215 is the third symbol (symbol number 2) or the fourth symbol (symbol number 2) of the transmission time interval (e.g., slot 250). 3). DMRS 220 symbol location can be configured in a Master Information Block (MIB). In Type A mapping scenarios, the start symbol of PDSCH 215 may be symbol number 0, 1, 2, or 3 of slot 250. The start symbol of the PDSCH may be dynamically configured in the TDRA (time-domain resource allocation) field of the DCI that may be included in the PDCCH 210. When considering processing complexity, among other considerations, UE 115-a must ensure that PDCCH 210 scheduling PDSCH 215 is received in the same slot 250 and is not included in the first three symbols of the slot. If not, one may not expect to receive a PDSCH 215 with Type A mapping (as illustrated in communications 205-a) in slot 205. As illustrated, the PDCCH 210 is included in the first three symbols 225 and thus satisfies the rule. However, if the PDCCH 210 is not included in the first three symbols 225, the UE 115-a may generate an error, ignore the resources, or depending on the UE 115-a implementation. Some other actions can be performed.

[0109] As illustrated in communication 205-a, wireless communication system 200 may support CSI reporting. DCI 235 (e.g., included in PDCCH 210), which may be an example of a DCI format 0_1 or 0_2 uplink DCI, may trigger a CSI report on the PUSCH, which may be referred to as an aperiodic CSI report. The DCI may include a CSI request field indicating a trigger state among a plurality of trigger states configured with RRC (e.g., via the upper layer parameter AperiodicTriggerStateList). Each trigger state in the list can be linked to a CSI-RS resource set, and each CSI-RS resource set can have multiple CSI-RS resources. UE 115-a may measure CSI-RS resources (e.g., CSI-RS resources 230) and transmit a CSI report over resources of PUSCH. To determine the location of CSI-RS resources, a slot offset may be configured for each CSI-RS resource set using control messaging such as RRC. If the slot offset of the CSI-RS resource set associated with the trigger state indicated in the DCI is 0, the CSI-RS resource in the CSI-RS resource set is received in the same slot as the DCI. When considering processing complexity, among other considerations, the UE 115-a must use the OFDM symbol(s) ( 225) It may not be expected that aperiodic CSI-RS will be transmitted previously. However, in cases where CSI-RS resources 230 are before DCI 235, UE 115-a generates an error or ignores the resources, as illustrated in communications 205-b. Alternatively, other operations may be performed depending on the UE (115-a) implementation.

[0110] The wireless communication system 200 may also support configuring the UE 115-a with a set of control resource sets (CORESETs) of the bandwidth portion of the serving cell. Each CORESET may be associated with an active transmission configuration indicator (TCI) state. RRC signaling can be used to configure the number of symbols of the CORESET and resource blocks in the frequency domain as part of the CORESET configurations. A PDCCH search space set (SS set) may be associated with one CORESET, and search space sets of the upper limit (eg, 10) of the bandwidth portion of the component carrier/serving cell may be determined. Control signaling, such as RRC signaling, configures the search space set with the associated CORESET, monitors slot periodicity and offset, symbols within the slot (e.g., to determine PDCCH monitoring opportunities in the search space set), and DCI formats to monitor. , and can be used to monitor the number of PDCCH candidates for a given aggregation level.

[0111] PDCCH candidates can be defined as part of search space set configurations. A PDCCH candidate with a given aggregation level and a given candidate index is defined in a given search space set. DCI may be received in one PDCCH candidate, and UE 115-a may monitor the PDCCH candidates in search space sets. One or more candidates with a cyclic redundancy check passing (successful decoding) may correspond to the decoded DCI, and UE 115-a may blind decode the DCI.

[0112] As described herein, wireless communication system 200 can support PDCCH repetitions, where each repetition is a PDCCH candidate. Two PDCCH candidates may carry the same DCI and therefore may be considered “linked.” The two linked PDCCH candidates may have the same aggregation level (same number of control channel elements) and the DCI payload transmitted using the two PDCCH candidates may be the same. UE 115-b may perform soft combining of multiple PDCCH candidates to decode DCI. To support soft combining, UE 115-a may be configured to identify linked PDCCH candidates. To support linking, two search space sets (carrying PDCCH candidates) can be linked via control signaling, such as RRC signaling. The monitoring opportunities of the two linked search space sets can be mapped one-to-one. PDCCH candidates with the same aggregation level and the same candidate index in two linked search space sets may be linked, and the two linked search space sets consist of the same number of candidates for each aggregation level. It can be.

[0113] The first set of search spaces 240 and the second set of search spaces 245 are illustrated in slot 250. Arrows crossing the first search space set 240 and the second search space set 245 illustrate linked PDCCH candidates within the individual search space sets. Communications 205-c and 205-d illustrate possible search space set configurations, but it should be understood that other configurations are contemplated within the scope of this disclosure.

[0114] DCI 235 scheduling a PDSCH 215 with mapping type A, or when DCI 235 triggers one or more aperiodic CSI-RS resources and DCI 235 schedules one or both of the linked PDCCH candidates When received in the same slot as , resource considerations regarding PDSCH resources and CSI-RS resources may be unclear. More specifically, since the UE 115-a can decode the DCI in the first PDCCH repetition, the second PDCCH repetition, or both the first and second repetitions, the network (e.g., base station 105-a) It may not be possible to identify the repetition carrying the DCI that the UE is decoding. In such cases, it may not be possible for UE 115-a to determine where to consider resources for PDCCH or DCI.

[0115] Implementations described herein provide one or more confirmation rules that the UE 115-a can apply when some conditions occur. For example, UE 115-a detects DCI 235 in the linked PDCCH candidates for PDCCH repetition (e.g., in the two corresponding search space sets and monitoring opportunities linked) and determines that the DCI has mapping type A. When scheduling a PDSCH with Any verification rules you consider can be applied. In some cases, UE 115-a determines whether the PDCCH candidates are inter-slot or intra-slot to determine whether one or both candidates are within a threshold number of symbols from the beginning of the slot. It can be taken into consideration.

[0116] Figures 3A and 3B illustrate examples of resource diagrams 300 showing identifying resources associated with repetition-based linked downlink control channel candidates, in accordance with aspects of the present disclosure. In some examples, resource diagrams may implement aspects of wireless communication system 100. For example, UE 115 may receive from base station 105 (as described with reference to FIGS. 1 and 2) a first PDCCH candidate in a first search space set linked to a second PDCCH candidate in a second search space set. An indication may be received that the first PDCCH candidate at least partially precedes the second PDCCH candidate. In some examples, as illustrated in FIG. 3A, a first PDCCH candidate may reside in a first slot (eg, TTI) and a second PDCCH candidate may reside in a second slot. Alternatively, as illustrated in FIG. 3B, the first PDCCH candidate and the second PDCCH candidate may reside in a common slot. As explained in more detail, the DCI of the linked PDCCH candidates in FIGS. 3A and 3B schedules a PDSCH (e.g., a PDSCH with Type A mapping) in the slot (e.g., TTI) of at least one of the linked candidates. . Accordingly, the UE and base station can apply confirmation rules to determine whether PDSCH resources and PDCCH candidates are valid.

[0117] Figure 3A illustrates a resource diagram 300-a including a first TTI 305-a and a second TTI 305-b. In some cases, the first PDCCH candidate 310-a corresponding to the first search space may be in the first TTI 305-a and the second PDCCH candidate 310-b corresponding to the second search space. ) may be in the second TTI (305-b). The positions of the search space sets and thus the linked PDCCH candidates 310 may be configured by the base station. In some cases, the base station transmits to the UE an indication that the first PDCCH candidate 310-a (e.g., the first PDCCH candidate) is linked to the second PDCCH candidate 310-b (e.g., the second PDCCH candidate). can do. Specifically, the base station may transmit and the UE may receive at least one RRC message indicating that the first search space and the second search space are linked (eg, for repetition). The representation may be in the form of a CORESET and search space set configuration as described with respect to FIG. 2. Based on the first search space, the second search space, and RRC, the UE may determine that the first PDCCH candidate 310-a and the second PDCCH candidate 310-b are linked. Additionally, the base station may schedule the search space set such that the first PDCCH candidate 310-a at least partially precedes the second PDCCH candidate 310-b. Moreover, based on the indication, the UE determines whether the first PDCCH candidate 310-a is positioned within the first TTI 305-a and the second PDCCH candidate 310-b is positioned within the second TTI 305-b. (e.g., slot-to-slot positioning).

[0118] Because the PDCCH candidates 310 can be linked, the PDCCH candidates can carry the same DCI payload. The UE may decode the DCI of the first PDCCH candidate 310-a, the second PDCCH candidate 310-b, or both. The UE may determine that the DCI schedules resources for PDSCH with type A resource mapping. For example, the UE may determine that the DCI schedules resources for the PDSCH in the second TTI 305-b including the second PDCCH candidate 310-b. Because PDSCH resources are scheduled in a slot (e.g., second TTI 305-b) that contains a linked PDCCH candidate (e.g., PDCCH candidate 310-b) carrying a scheduling DCI, the UE is scheduled for the PDSCH. A confirmation rule to confirm that the second PDCCH candidate (310-b) is positioned within a threshold number of symbols (e.g., three symbols) at the beginning of the second TTI (305-b) corresponding to the resources It can be applied. More specifically, if the PDCCH candidates are positioned inter-slot as illustrated in FIG. 3A and the PDSCH 315 is scheduled in the same slot as the later PDCCH candidate (e.g., the second PDCCH candidate 310-b), the UE Confirmation rules can be applied. Based on the determination and confirmation, the base station may transmit and the UE may receive a downlink message in the confirmed resources containing a Type A resource mapping corresponding to the scheduled PDSCH resources.

[0119] FIG. 3B illustrates a resource diagram 300-b including a first PDCCH candidate 320-a and a second PDCCH candidate 320-b within a TTI 325 (e.g., a slot). The base station may transmit an indication (e.g., RRC configuration) to the UE that the first PDCCH candidate 320-a is linked to the second PDCCH candidate 320-b. Based on the indication, the UE may determine that the first PDCCH candidate 320-a and the second PDCCH candidate 320-b are linked. The configuration may specify that both the first PDCCH candidate 320-a and the second PDCCH candidate 320-b are positioned within the TTI 325 (e.g., in-slot positioning). The base station transmits DCI in the first PDCCH candidate 320-a and the second PDCCH candidate 320-b. The UE may decode the DCI associated with the first PDCCH candidate 320-a, the second PDCCH candidate 320-b, or both. The UE may determine that the DCI schedules resources for PDSCH 330 with type A resource mapping.

[0120] In some cases, the UE and the base station determine the first PDCCH candidate 320-a and the second PDCCH candidate 320-a within the TTI 325 for which resources (e.g., a PDSCH with type A resource mapping) are scheduled. It can be determined that b) is positioned. Based on the decision, the UE and the base station determine the positions of the first PDCCH candidate 320-a and the second PDCCH candidate 320-b within the TTI 325 and for PDSCH resources scheduled in the same TTI 325. Verification rules can be applied to verify them. Specifically, the UE and the base station may determine that one or both of the first PDCCH candidate 320-a and the second PDCCH candidate 320-b exceeds a threshold number of symbols at the beginning of the TTI 325 (e.g., in some implementations It can be confirmed that it is positioned within one or more of the first three symbols). Accordingly, when both PDCCH candidates 320 are positioned on the same TTI of PDSCH 330 with Type A mapping, the UE and base station must determine whether one or both of the PDCCH candidates 320 are validly deployed. Confirmation rules can be applied for The device may apply either rule (eg, identifying one or both candidate positionings), and the applied rule may be based on UE implementation, pre-configuration, or configuration from the base station. Based on the determination and confirmation, the base station may transmit and the UE may receive at least one downlink message within the identified resources of PDSCH 330.

[0121] Therefore, as illustrated in FIGS. 3A and 3B, when the DCI of the linked candidate schedules a PDSCH with Type A mapping in the linked candidate, the UE determines that the resources of the PDSCH and/or PDCCH candidates are available. To check , one of the rules that can be followed for positioning of PDCCH candidates can be applied. These techniques can support improved communication reliability and efficiency by reducing resource complexity.

[0122] Figure 4 illustrates an example of a resource diagram 400 that supports identifying resources associated with repetition-based linked downlink control channel candidates, in accordance with aspects of the present disclosure. In some examples, resource diagram 400 may implement aspects of wireless communication systems 100 and 200. For example, UE 115 may receive from base station 105 (as described with reference to FIGS. 1 and 2) a first PDCCH candidate in a first search space set linked to a second PDCCH candidate in a second search space set. An indication may be received that the first PDCCH candidate precedes the second PDCCH candidate at least in part based on the search space set configuration. Search set configuration can be configured using control messaging, such as RRC messaging. In some examples, the first PDCCH candidate and the second PDCCH candidate may reside in a common slot (e.g., TTI 405) based on the configuration of respective search space sets corresponding to the linked PDCCH candidates.

[0123] The base station may transmit DCI including a CSI request to the UE through the first PDCCH candidate 410-a and the second PDCCH candidate 410-b. The CSI request may include fields (e.g., trigger status indication) corresponding to the CSI-RS resource 415 that the UE will use for measurement and CSI reporting. The UE decodes the DCI from the first PDCCH candidate 410-a, the second PDCCH candidate 410-b, or both, and uses the CSI request included in the DCI and the corresponding CSI-RS resources 415. can be identified. In some cases, the UE may determine which slot the CSI-RS resource 415 is positioned based on the offset indication of the DCI as discussed in FIG. 2. If the CSI-RS resources 415 are scheduled in the same slot as the DCI that triggers the CSI-RS resources 415 (e.g., if the offset indication of the DCI is 0), the UE and base station may send the CSI request and Confirmation rules may be applied to determine that associated reference signal resources (e.g., CSI-RS resources 415) are validly scheduled. That is, the UE may not expect that the CSI-RS resources 415 are scheduled before the OFDM symbols of one or both of the PDCCH candidates 410 carrying the triggering DCI. In some examples, the rule specifies that only the earliest PDCCH candidate is considered (e.g., CSI-RS resources 415-b will be positioned after the start symbol of the earliest PDCCH candidate 410-a). In other examples, the rules specify that both PDCCH candidates are considered (e.g., CSI-RS resources 415-c will be positioned after the start symbol of both PDCCH candidates 410). Which rules are applied can be pre-configured, or configured by the base station, and so on.

[0124] If the CSI-RS resources 415 are not scheduled effectively, the UE 115 may generate an error, ignore invalid resources, or perform some other operation depending on the implementation. For example, as illustrated in Figure 4, CSI-RS resource 415-a may not satisfy the confirmation rule due to its position before the earliest PDCCH candidate (and both PDCCH candidates 410), and thus The UE may generate an error, ignore the CSI-RS resource 415-a, ignore DCI, or perform some other operation. If the CSI-RS resources 415 satisfy the confirmation rule, the UE can measure the CSI-RS resources 415 and transmit a CSI report to the base station.

[0125] Therefore, as illustrated in Figure 4, when the DCI of a linked candidate triggers CSI-RS resources in a TTI containing the linked candidates, the UE determines whether the resources of the CSI-RS and/or PDCCH candidates are available. You can apply one of the rules to check that These techniques can support improved communication reliability and efficiency by reducing resource complexity.

[0126] Figure 5 illustrates an example of a process flow diagram 500 that supports identifying resources associated with repetition-based linked downlink control channel candidates, in accordance with aspects of the present disclosure. Process flow diagram 500 includes aspects of wireless communication system 100 of FIG. 1 and 200 of FIG. 2. For example, the process flow diagram includes base station 105-b and UE 115-b, which may be examples of corresponding devices described in connection with FIG. 1 . Base station 105-b and UE 115-b may use various resources for communications, such as resources illustrated in resource diagrams 300 of FIG. 3 and resource diagram 400 of FIG. 4.

[0127] At 505, the UE 115-b sends an indication to the base station 105-b that the first downlink control channel candidate in the first set of search spaces is linked to the second downlink control channel candidate in the second set of search spaces. ) can be received from. The first downlink control channel candidate may be received at least partially before the second downlink control channel candidate. The indication may be in the form of an RRC configuration of individual search space sets corresponding to control channel candidates. UE 115-b may monitor the search space set to identify control channel candidates.

[0128] At 510, the UE 115-b may decode downlink control information from at least one of the first downlink control channel candidate or the second downlink control channel candidate. In some examples, the downlink control information may schedule resources for a downlink shared channel (eg, PDSCH) in a transmission time interval that includes at least the second downlink control channel candidate. In some examples, downlink control information may include a channel state information request.

[0129] At 515, the UE 115-b may apply confirmation rules based on resources scheduled or triggered by DCI. For example, if the DCI schedules PDSCH resources for a downlink shared channel in a transmission time interval that includes one or both of the downlink control channel candidates, the confirmation rule may determine whether the first downlink control channel candidate or the second downlink At least one of the control channel candidates may be within a threshold number of symbols from the beginning of the transmission time interval for which resources are scheduled. In some cases, the rule applied is based on the first downlink control channel candidate and the second downlink control channel candidate being positioned at separate transmission time intervals. In these cases, UE 115-b may confirm that the second downlink control channel candidate is positioned within a threshold number of symbols of the second transmission time interval. In some cases, the rule applied is based on both downlink control channel candidates being positioned in the same transmission time interval in which the downlink shared channel resources are scheduled. In these cases, UE 115-b determines whether both the first downlink control channel candidate and the second downlink control channel candidate are positioned within a threshold number of symbols of the transmission time interval or the first downlink control channel candidate. It can be confirmed that at least one of the candidate and the second downlink control channel candidate is positioned within a threshold number of symbols of the transmission time interval.

[0130] In some cases where the DCI includes a channel state information request, the confirmation rule may be that the reference signal resources associated with the channel state information request are positioned at least after the start symbol of the first downlink control channel candidate. In cases where the DCI includes a channel state information request, the confirmation rule is that the reference signal resources are positioned after the start symbol of the first and second downlink control channel candidates.

[0131] At 520, when the DCI schedules the downlink shared channel, the UE 115-b determines at least the satisfaction of the confirmation rule associated with which the first downlink control channel candidate and the second downlink control channel candidate are linked. Based in part, a downlink message of resources may be received from the base station 105-b.

[0132] At 525, if the DCI includes a channel state information request, UE 115-b determines upon satisfaction of the confirmation rule associated with the first downlink control channel candidate and the second downlink control channel candidate being linked. A channel state information report may be transmitted to base station 105-b based, at least in part, on the base station 105-b.

[0133] Figure 6 shows a block diagram 600 of a device 605 that supports identifying resources associated with repetition-based linked downlink control channel candidates, in accordance with aspects of the present disclosure. Device 605 may be an example of aspects of UE 115 as described herein. Device 605 may include a receiver 610, a transmitter 615, and a communication manager 620. Device 605 may also include a processor. Each of these components may communicate with each other (eg, via one or more buses).

[0134] The receiver 610 may receive information, such as packets, user data, control information, or various information channels (e.g., control channels associated with identifying resources associated with repetition-based linked downlink control channel candidates, means for receiving associated data channels, information channels, and any combination thereof. Information may be passed on to other components of device 605. Receiver 610 may utilize a single antenna or a set of multiple antennas.

[0135] Transmitter 615 may provide a means for transmitting signals generated by other components of device 605. For example, transmitter 615 may transmit information, such as packets, user data, control information, or various information channels (e.g., control channels, data associated with identifying resources associated with repetition-based linked downlink control channel candidates). Any combination of these associated channels (channels, information channels) can be transmitted. In some examples, transmitter 615 may be co-located with receiver 610 in a transceiver module. Transmitter 615 may utilize a single antenna or a set of multiple antennas.

For example, communication manager 620 may receive information from receiver 610, transmit information to transmitter 615, or receive information, transmit information, or perform various other operations as described herein. It may be integrated with the receiver 610, the transmitter 615, or both.

[0140] Communication manager 620 may support wireless communication at the UE according to examples disclosed herein. For example, communication manager 620 may be configured as means for receiving an indication from a base station that a first downlink control channel candidate in a first set of search spaces is linked to a second downlink control channel candidate in a second set of search spaces, or Alternatively, such means may be supported, wherein the first downlink control channel candidate is received at least partially before the second downlink control channel candidate. Communications manager 620 may be configured with or otherwise support means for decoding downlink control information from at least one of the first downlink control channel candidate or the second downlink control channel candidate, and may be configured to support downlink control. The information schedules resources for the downlink shared channel in a transmission time interval that includes at least the second downlink control channel candidate. Communications manager 620 is configured as means for receiving downlink messages from resources based on satisfaction of confirmation rules associated with which the first downlink control channel candidate and the second downlink control channel candidate are linked or otherwise. Such means may support, wherein the confirmation rule is that at least one of the first downlink control channel candidate or the second downlink control channel candidate is within a threshold number of symbols at the beginning of the transmission time interval for which resources are scheduled.

[0141] Additionally or alternatively, communication manager 620 may support wireless communications at the UE according to examples as disclosed herein. For example, communication manager 620 may be configured as means for receiving an indication from a base station that a first downlink control channel candidate in a first set of search spaces is linked to a second downlink control channel candidate in a second set of search spaces, or Alternatively, such means may be supported, wherein the first downlink control channel candidate is received at least partially before the second downlink control channel candidate.
