Blind decoding restriction techniques for wireless communications

Abstract

Methods, systems, and apparatus for supporting blind decoding constraint adjustment techniques in wireless communication are described. A base station can configure a user equipment (UE) with one or more conditions that can trigger an adjustment to the number of blind decoding candidates to be monitored at the UE for control information communications from the base station. A nominal number of blind decoding candidates can be configured at the UE, and the adjustment to the number of blind decoding candidates can reduce the nominal number, thereby allowing the UE to perform blind decoding with less processing power, less time, or both. The triggering conditions may include one or more configured conditions that can support reliable communication with fewer blind decoding candidates.

Description

Technical Field

[0001] The following text relates to wireless communication, including blind decoding restriction techniques for wireless communication. Background Technology

[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, and broadcasting. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of these multiple access systems include fourth-generation (4G) systems such as Long Term Evolution (LTE), LTE-A Advanced (LTE-A), or LTE-A Pro systems, and fifth-generation (5G) systems, which may be referred to as New Radio (NR) systems. These systems can 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 Spectrum 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 base station or network access node simultaneously supporting communication for multiple communication devices, which may otherwise be referred to as User Equipment (UE).

[0003] In some wireless systems, the base station can send control information to the UE using a downlink control channel (e.g., the Physical Downlink Control Channel (PDCCH)). In some cases, the UE can monitor several resources within the downlink control channel based on one or more search spaces configured at the UE. In such cases, each UE can perform blind decoding on multiple possible downlink resources that may contain control information for the UE, based on the configured search space. If the UE (e.g., based on downlink communication being scrambled by the UE's Radio Network Temporary Identifier (RNTI)) detects control information indicating the UE's identity, the UE can decode and process the control information. Such blind decoding can consume relatively large amounts of processing resources and power at the UE, and therefore, efficient techniques for blind decoding can help improve UE efficiency and reduce power consumption. Summary of the Invention

[0004] The described technology relates to improved methods, systems, devices, and apparatuses supporting blind decoding restriction techniques for wireless communications. In various aspects, a user equipment (UE) can receive configuration information from a base station that provides one or more conditions that can trigger an adjustment to the number of blind decoding candidates to be monitored for control information at the UE. In some cases, the UE can provide a capability indication to the base station that identifies the UE as capable of performing adjustments to blind decoding restrictions, and the base station can determine one or more triggering conditions that can trigger an adjustment to the number of blind decoding candidates at the UE.

[0005] In some cases, a nominal number of blind decoding candidates can be configured at the UE, and adjustments to the number of blind decoding candidates can reduce the nominal number, allowing the UE to perform blind decoding with less processing power, less time, or both. In other cases, the adjustment can increase the nominal number of blind decoding candidates, allowing additional UEs to receive control information from the base station for a period of time compared to the nominal number. In some cases, triggering conditions may include one or more of the following: a change in the bandwidth portion (BWP) at the UE, a beam change at the UE, a periodic time slot set, a monitored control resource set (CORESET) (e.g., a dynamic or UE-requested CORESET may have a reduced number of blind decoding candidates), the presence of control channel information transmitted using downlink shared channel resources (e.g., equipped with DCI), or any combination thereof. In some cases, adjustments to blind decoding restrictions can be configured via Radio Resource Control (RRC) signaling, indicated in the downlink control information (DCI) sent to the UE, indicated in the Media Access Control (MAC) control element (CE), or any combination thereof.

[0041] In some wireless communication systems, base stations can use downlink control channels (e.g., physical downlink control channel (PDCCH)) to send control information to user equipment (UE). To monitor control information, the UE can monitor one or more search spaces within the downlink control channel resources. In such a case, each UE can perform blind decoding on multiple possible downlink resources that may contain control information for the UE, based on the configured search space. If the UE detects control information that identifies it (e.g., downlink communication scrambled by the UE's Radio Network Temporary Identifier (RNTI), the UE can decode and process the control information. Such blind decoding can consume relatively large amounts of processing resources and power at the UE.

[0042] Such blind decoding can consume processing resources and power of any type of UE, but it can be more burdensome in certain types of devices, such as low-cost devices that may have reduced capabilities. For example, in some NR deployments, reduced-capability (RedCap) UEs or NR-light UEs with lower costs and reduced capabilities can be deployed. For example, compared to a full-capability UE, such a reduced-capability UE may have fewer antennas, reduced transmit / receive bandwidth, limited battery capacity, reduced PDCCH blind decoding processing capability, limited storage capacity, or any combination thereof. Such reduced-capability UEs can be used for, for example, Internet of Things (IoT) use cases, such as smart wearables, industrial sensors, video surveillance equipment, etc. Therefore, in some NR cells, multiple types of UEs can exist, including regular UEs and reduced-capability UEs.

[0043] As indicated, during PDCCH reception, the UE can perform blind decoding because it may not know the number of Control Channel Elements (CCEs) currently occupied by the PDCCH, what downlink control information (DCI) format information has been transmitted, or where the required information is located. However, as part of the blind decoding process, the UE knows what information it expects, and it knows its Radio Network Temporary Identifier (RNTI) value. For example, in idle state, the UE expects paging or system information (SI) communication. In other examples, when initiating a Random Access Channel (RACH) procedure, the UE expects a RACH response, and when there is uplink data in the buffer waiting to be transmitted, the UE expects uplink permission. For different expected information, the UE uses the corresponding RNTI to perform a Cyclic Redundancy Check (CRC) on the received transport block (TB), which has a CRC scrambled using the corresponding RNTI. If the CRC check is successful, the UE knows that the information is what it needs and will further deduce the content of the message (e.g., the content of the DCI message). If the UE fails to decode the PDCCH, it will continue to try to decode the PDCCH using different sets of blind decoding candidates during upcoming PDCCH monitoring periods.

[0044] PDCCH candidates can be determined by the CCE aggregation level. For some DCI formats, a single CCE may not be sufficient to capture all DCI information; therefore, the CCE aggregation level is defined as combining several CCEs into a single PDCCH candidate. In some cases, the UE does not attempt to decode every PDCCH candidate but instead uses a search space (SS). This SS allows the scheduler at the base station some flexibility in selecting PDCCH resources while maintaining a manageable number of blind decoding attempts by the UE. In some cases, the SS set includes two types of SSs: a public SS set and a UE-specific SS set. In some deployments, the UE can use five UE-specific search space aggregation levels (1, 2, 4, 8, 16) and three public search space aggregation levels (4, 8, 16) to decode the PDCCH, which can provide multiple PDCCH candidates as blind decoding candidates within the search space. The UE PDCCH blind decoding capability can be defined for monitoring the UE's PDCCH, where the accurate aggregation level and the number of decoding candidates per aggregation level are configurable, and this can be regarded as a benchmark for the base station when configuring the aggregation level and / or the number of PDCCH candidates per aggregation level.

[0045] As indicated, additional blind decoding candidates can lead to higher power consumption and increased processing resource usage for the UE compared to scenarios with fewer blind decoding candidates. For example, fewer blind decoding candidates can reduce the number of blind decoding attempts (e.g., PDCCH candidate processing) in PDCCH monitoring. Furthermore, fewer blind decoding candidates can lead to faster completion of the PDCCH decoding process, allowing the UE to enter micro-sleep periods more quickly. However, reduced blind decoding limits can impose constraints on the base station scheduler and limit scheduling flexibility, potentially increasing latency and blocking probability (e.g., the probability that a UE's DCI will be blocked by another UE's DCI). Higher blocking probability due to smaller blind decoding limits can result in higher latency and negatively impact energy efficiency. Therefore, from a blind decoding perspective, providing reduced blind decoding limits for some UEs may be beneficial to the UEs but may limit the base station's scheduling flexibility and lead to increased latency and reduced energy efficiency. For example, in scenarios with a relatively large number of UEs, reduced blind decoding limits can lead to performance degradation because smaller blind decoding limits will increase the PDCCH blocking probability (BP). Furthermore, BP can depend on various factors, such as the number of UEs that need to be scheduled (e.g., this can depend on the UE's traffic), the size of the control resource set (CORESET) (e.g., the number of CCEs), the number of PDCCH candidates, and the PDCCH link performance / coverage (e.g., its impact on the aggregation level). Therefore, in some cases, simply providing a reduced blind decoding limit for some UEs (e.g., RedCap UEs) may not provide the desired efficiency.

[0046] Various aspects of this disclosure provide techniques for improving efficiency by providing adjustments to blind decoding limits under certain conditions, said one or more conditions, which provide improved efficiency through a reduction in the blind decoding limit. In various aspects, the UE may receive configuration information from a base station providing one or more conditions that can trigger an adjustment to the number of blind decoding candidates. In some cases, the UE may provide a capability indication to the base station, identifying the UE as capable of performing adjustments to the blind decoding limit, and the base station may determine one or more triggering conditions that can trigger an adjustment to the number of blind decoding candidates at the UE.

[0047] In some cases, a nominal number of blind decoding candidates can be configured at the UE, and adjustments to the number of blind decoding candidates can reduce the nominal number, allowing the UE to perform blind decoding with less processing power, less time, or both. In other cases, the adjustment can increase the nominal number of blind decoding candidates, allowing additional UEs to receive control information from the base station for a period of time compared to the nominal number of blind decoding candidates. In some cases, triggering conditions may include one or more of the following: a change in the bandwidth portion (BWP) at the UE, a beam change at the UE, whether a time slot in the search space is in a periodic time slot set, a monitored control resource set (CORESET) (e.g., a dynamic or UE-requested CORESET may have reduced blind decoding candidates), the presence of control channel information transmitted using downlink shared channel resources (e.g., equipped with DCI), or any combination thereof. In some cases, adjustments to blind decoding restrictions can be configured via Radio Resource Control (RRC) signaling, indicated to the UE in the DCI, indicated in the Media Access Control (MAC) control element (CE), or any combination thereof.

[0048] Specific aspects of the subject matter described herein can be implemented to achieve one or more advantages. The described techniques can support improvements in blind decoding frameworks to allow for efficient use of UE resources and adjustment of the number of blind decoding candidates based on conditions at the base station and UE. Such techniques can thereby reduce power consumption and processing resource usage, and improve the reliability of wireless communication, among other advantages. Therefore, supported techniques can include improved network operation, and in some examples, improved network efficiency, and other benefits.

[0049] The various aspects of this disclosure are first described in the context of wireless communication systems and processing flows. Further aspects of this disclosure are illustrated and described with reference to apparatus diagrams, system diagrams, and flowcharts relating to blind decoding limiting techniques for wireless communication.

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, an Advanced LTE (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, communication with low-cost and low-complexity devices, or any combination thereof.

[0051] Base stations 105 can be distributed throughout a geographic area to form a wireless communication system 100, and can be devices of different forms or with different capabilities. Base stations 105 and UE 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110 over which UE 115 and base station 105 can establish one or more communication links 125. Coverage area 110 can be an example of a geographic area over which base station 105 and UE 115 can support communication of signals according to one or more radio access technologies.

[0052] UE 115 can be distributed throughout the entire coverage area 110 of wireless communication system 100, and each UE 115 can be stationary, mobile, or both at different times. UE 115 can be devices with different forms or different capabilities. Figure 1 Some example UE 115s are shown in the document. The UE 115 described herein can be used with various types of devices (e.g., other UE 115s, base station 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices), such as Figure 1 (As shown) to communicate.

[0053] Base station 105 may communicate with core network 130, or with each other, or both. For example, base station 105 may interface with core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base station 105 may communicate with each other directly (e.g., directly between base stations 105) or indirectly (e.g., via core network 130) or directly and indirectly on backhaul links 120 (e.g., via X2, Xn, or other interfaces). In some examples, backhaul link 120 may be or include one or more radio links.

[0054] One or more base stations 105 described herein may include, or may be referred to by those skilled in the art as, base station transceiver, radio base station, access point, radio transceiver, node B, eNodeB (eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), home node B, home eNodeB or other suitable terms.

[0055] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscription device, or any other suitable term, wherein "device" may also be referred to as a cell, station, terminal, or client, etc. 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 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, which may be implemented in various objects such as home appliances, vehicles, or meters.

[0056] The UE 115 described in this document can communicate with various types of devices, such as other UEs 115 that can sometimes act as repeaters, as well as base station 105 and network devices (including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations), etc. Figure 1 As shown.

[0057] UE 115 and base station 105 can wirelessly communicate with each other via one or more communication links 125 on one or more carriers. The term "carrier" can refer to a set of radio spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of radio spectrum band (e.g., a bandwidth portion (BWP)) operating according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating the operation of the carrier, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation can be used with frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0058] In some examples (e.g., in a carrier aggregation configuration), the carrier may also have acquisition signaling or control signaling to coordinate the operation of other carriers. The carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Channel Number (EARFCN)) and can be located according to a channel grid for discovery by UE 115. The carrier can operate in standalone mode, where initial acquisition and connection can be performed by UE 115 via the carrier, or the carrier can operate in non-standalone mode, where different carriers (e.g., with the same or different radio access technologies) are used to anchor the connection.

[0059] The communication link 125 shown in the wireless communication system 100 may include uplink transmission from UE 115 to base station 105, or downlink transmission from base station 105 to UE 115. The carrier may carry downlink or uplink communication (e.g., in FDD mode), or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).

[0060] A carrier can be associated with a specific bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth can be referred to as the carrier or the "system bandwidth" of the wireless communication system 100. For example, the carrier bandwidth can be one of several defined bandwidths of a carrier used for a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). Devices of the wireless communication system 100 (e.g., base station 105 or UE 115, or both) can have a hardware configuration that supports communication over a specific carrier bandwidth, or can be configured to support communication over one carrier bandwidth in a set of carrier bandwidths. In some examples, the wireless communication system 100 may include base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 can be configured to operate on a portion (e.g., a subband, BWP) or all of the carrier bandwidth.

[0061] The signal waveform transmitted on a carrier can consist of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element can include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements UE 115 receives and the higher the order of the modulation scheme, the higher the data rate that can be used for UE 115. Wireless communication resources can refer to a combination of radio spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further increase the data rate or data integrity used for communication with UE 115.

[0062] One or more digital schemes (numerologies) can be supported for a carrier, where the digital scheme may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier can be divided into one or more BWPs with the same or different digital schemes. In some examples, UE 115 can be configured with multiple BWPs. In some examples, a single BWP for a carrier can be active at a given time, and communication for UE 115 can be restricted to one or more active BWPs.

[0063] The time interval used for base station 105 or UE 115 can be expressed as a multiple of a basic time unit, such as T. s =1 / (Δf) max ·N f The sampling period is ) seconds, where Δf max This can represent the maximum supported subcarrier spacing, and N f This can represent the maximum supported Discrete Fourier Transform (DFT) size. The time intervals of communication resources can be organized based on radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0064] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame (e.g., in the time domain) may be divided into multiple subframes, and each subframe may be further divided into multiple time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of symbol periods (e.g., depending on the length of the cyclic prefix preceding each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple mini-time slots containing one or more symbols. In addition to the cyclic prefix, each symbol period may contain one or more (e.g., N) symbols. f (Number) sampling periods. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.

[0065] A subframe, time slot, mini-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0066] Physical channels can be multiplexed on a carrier using various techniques. For example, one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels on a downlink carrier. A control region (e.g., a control resource set (CORESET)) for the physical control channel can be defined by the number of symbol periods and can be extended over the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESET) can be configured for a set in UE 115. For example, one or more UEs in UE 115 can monitor or search control regions for control information based on one or more search space sets, and each search space set can include one or more control channel candidates from one or more aggregation levels arranged in a concatenated manner. The aggregation level for the control channel candidates can refer to the 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 set may include a common search space set configured to send control information to multiple UEs 115 and a UE-specific search space set configured to send control information to a specific UE 115.

[0067] In some examples, base station 105 may be mobile, and thus provide communication coverage for mobile geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but 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. Wireless communication system 100 may include, for example, a heterogeneous network, in which different types of base stations 105 use the same or different radio access technologies to provide coverage for various geographic coverage areas 110.

[0068] Some UE 115s (e.g., MTC or IoT devices) can be low-cost or low-complexity devices and can provide automated machine-to-machine communication (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with base station 105 without human intervention. In some examples, M2M communication or MTC can include communication from devices that have integrated sensors or meters to measure or capture information and relay such information to a central server or application that uses the information or presents it to humans interacting with the application. Some UE 115s can be designed to collect information or automate the 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, climate and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business billing.

[0069] Some UE 115s can be configured to operate in a power-saving mode, such as half-duplex communication (e.g., a mode that supports unidirectional communication via either transmission or reception, rather than simultaneous transmission and reception). In some examples, half-duplex communication can be performed at a reduced peak rate. Other power-saving techniques for UE 115 include entering a power-saving deep sleep mode when not engaged in active communication, when operating on limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UE 115s can be configured to operate using a narrowband protocol type that is associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs) within a carrier, within a carrier's guard band, or outside a carrier.

[0070] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private or group communication and can be supported by one or more mission-critical services such as Mission-Critical Talk-to-Talk (MCPTT), Mission-Critical Video (MCVideo), or Mission-Critical Data (MCData). Support for mission-critical functions can include service prioritization, and mission-critical services can be used for public safety or general business applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency are used interchangeably herein.

[0071] In some examples, UE 115 may also be able to communicate directly with other UE 115 via device-to-device (D2D) communication link 135 (e.g., using point-to-point (P2P) or D2D protocols). One or more UE 115s utilizing D2D communication may be within the geographic coverage area 110 of base station 105. Other UE 115s in such a group may be outside the geographic coverage area 110 of base station 105, or otherwise unable to receive transmissions from base station 105. In some examples, the group of UE 115s communicating via D2D communication may employ a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UE 115s without involving base station 105.

[0072] In some systems, the D2D communication link 135 may be an example of a communication channel (e.g., a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, vehicles may communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these. Vehicles may signal information relating to traffic conditions, signal control, weather, safety, emergencies, or any other information relating to the V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure (e.g., roadside units), or communicate with the network via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communication, or both.

[0073] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), and may include at least one control plane entity (e.g., a Mobility Management Entity (MME), Access and Mobility Management Function (AMF)) managing access and mobility, and at least one user plane entity (e.g., a Serving Gateway (S-GW), Packet Data Network (PDN) Gateway (P-GW), User Plane Function (UPF)) routing packets or interconnects to external networks. The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by base station 105 associated with core network 130. User IP packets can be transmitted through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can connect to IP service 150 for one or more network operators. IP service 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0074] Some network devices (e.g., base station 105) may include sub-components, such as access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with UE 115 through one or more other access network transport entities 145, which may be referred to as a radio headend, smart radio headend, or transmit / receive point (TRP). Each access network transport 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 may be distributed across various network devices (e.g., radio headends and ANCs) or combined into a single network device (e.g., base station 105).

[0075] Wireless communication system 100 can operate using one or more frequency bands (typically in the range of 300 MHz to 300 GHz). The region from 300 MHz to 3 GHz is often referred to as the Ultra High Frequency (UHF) region or decimeter band because the wavelength range is from approximately one decimeter to one meter. UHF waves may be blocked or redirected by buildings and environmental features, but the waves may be strong enough to penetrate structures to allow macrocells to provide service to UE 115 located indoors. Compared to transmissions using smaller frequencies and longer wavelengths in the High Frequency (HF) or Extreme High Frequency (VHF) portions of the spectrum below 300 MHz, UHF wave transmission can be associated with smaller antennas and shorter distances (e.g., less than 100 km).

[0076] The wireless communication system 100 can also operate in the ultra-high frequency (SHF) region using a frequency band from 3 GHz to 30 GHz (also known as the centimeter band), or in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also known as the millimeter band). In some examples, the wireless communication system 100 can support millimeter-wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the individual devices can be smaller and more closely spaced than UHF antennas. In some examples, this can facilitate the use of antenna arrays within the devices. However, the propagation of EHF transmissions may suffer even greater atmospheric attenuation and a shorter range than SHF or UHF transmissions. Transmissions using one or more different frequency regions can employ the techniques disclosed herein, and the designated use of frequency bands across these frequency regions may vary by country or regulatory authority.

[0077] Wireless communication system 100 can use both licensed and unlicensed radio frequency spectrum bands. For example, wireless communication system 100 can employ Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology in unlicensed bands such as the 5 GHz Industrial, Scientific, and Medical (ISM) band. When operating in unlicensed radio frequency spectrum bands, devices such as base station 105 and UE 115 can employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed bands can be based on carrier aggregation configuration combined with component carriers operating in licensed bands (e.g., LAA). Operation in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, etc.

[0078] Base station 105 or UE 115 may be equipped with multiple antennas, which can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels, which can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be located together at an antenna assembly, such as an antenna tower. In some examples, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 may have an antenna array with a number of rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, antenna panels may support radio frequency beamforming for signals transmitted via antenna ports.

[0079] Base station 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such a technique can be called spatial multiplexing. For example, a transmitting device can transmit multiple signals via different antennas or different combinations of antennas. Similarly, a receiving device can receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can 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 multi-user MIMO (MU-MIMO) (where multiple spatial layers are transmitted to multiple devices).

[0080] Beamforming, also known as spatial filtering, directional transmission, or directional reception, is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105 or UE 115) to shape or guide antenna beams (e.g., transmit or receive beams) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array, such that some signals propagating relative to a particular orientation of the antenna array experience constructive interference, while other signals experience destructive interference. Adjustment of the signals transmitted via the antenna elements can include the transmitting or receiving device applying amplitude, phase shift, or both to the signals carried via the antenna elements associated with the device. The adjustment associated with each antenna element can be defined by a beamforming weight set associated with a particular orientation (e.g., the antenna array relative to the transmitting or receiving device, or relative to some other orientation).

[0081] Base station 105 or UE 115 may use beam scanning technology as part of beamforming operations. For example, base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by base station 105 in different directions. For example, base station 105 may transmit signals according to different beamforming weight sets associated with different transmission directions. Transmissions in different beam directions may be used to identify (e.g., by a transmitting device (such as base station 105) or a receiving device (such as UE 115)) the beam direction for subsequent transmission or reception by base station 105.

[0082] Base station 105 may transmit signals (such as data signals associated with a specific receiving device) in a single beam direction (e.g., the direction associated with a receiving device, such as UE 115). In some examples, the beam direction associated with transmission along a single beam direction may be determined based on the signals transmitted in one or more beam directions. For example, UE 115 may receive one or more signals from a plurality of signals transmitted by base station 105 in different directions, and may report to base station 105 an indication of the signal received by UE 115 with the highest signal quality or otherwise with acceptable signal quality.

[0083] In some examples, multiple beam directions can be used to perform transmissions by a device (e.g., base station 105 or UE 115), and the device can use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from base station 105 to UE 115). UE 115 can report feedback indicating precoding weights for one or more beam directions, and this feedback can correspond to the configured number of beams across the system bandwidth or one or more subbands. Base station 105 can transmit reference signals (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)), which may or may not be precoded. UE 115 can provide feedback for beam selection, which can 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 by base station 105 in one or more directions, UE 115 may employ similar techniques for transmitting signals multiple times in different directions (e.g., for identifying beam directions for subsequent transmission or reception by UE 115) or for transmitting signals in a single direction (e.g., for transmitting data to a receiving device).

[0084] When receiving various signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105, the receiving device (e.g., UE 115) can attempt multiple receiving configurations (e.g., directional listening). For example, the receiving device can attempt multiple receiving directions by: receiving via different antenna subarrays; processing the received signal according to different antenna subarrays; receiving according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array (e.g., different sets of directional listening weights); or processing the received signal according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array. Any of these operations can be referred to as "listening" according to different receiving configurations or receiving directions. In some examples, the receiving device can use a single receiving configuration to receive along a single beam direction (e.g., when receiving data signals). A single receiver configuration can be aligned on a beam direction determined based on listening according to different receiver 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).

[0085] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or Packet Data Convergence Protocol (PDCP) layer can be IP-based. The Radio Link Control (RLC) layer can perform packet segmentation and reassembly for communication on logical channels. The Media Access Control (MAC) layer can perform priority processing and multiplexing of logical channels to transport channels. The MAC layer can 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 can provide the establishment, configuration, and maintenance of RRC connections (which support radio bearers for user plane data) between the UE 115 and the base station 105 or core network 130. At the physical layer, transport channels can be mapped to physical channels.

[0086] In some cases, one or more UEs 115 may perform blind decoding on one or more PDCCH candidates within one search space to attempt to decode DCI from base station 105. In some cases, some UEs 115 and base station 105 may adjust the blind decoding limit if one or more conditions are met that would provide increased efficiency through a reduction in the blind decoding limit. In some cases, UE 115 may receive configuration information from base station 105 that provides one or more conditions that can trigger an adjustment to the number of blind decoding candidates. In some cases, UE 115 may provide base station 105 with an indication of its ability to perform adjustments to the blind decoding limit, and base station 105 may determine one or more triggering conditions that can trigger an adjustment to the number of blind decoding candidates at UE 115.

[0087] Figure 2 Examples of a wireless communication system 200 supporting blind decoding restriction techniques for wireless communication according to various aspects of this disclosure are shown. In some examples, the wireless communication system 200 may implement various aspects of the wireless communication system 100. The wireless communication system 200 may include a base station 105-a and a UE 115-a, which may respectively refer to... Figure 1 Examples of base station 105 and UE 115 are described.

[0088] In this example, base station 105-a can send downlink communication to UE 115-a via downlink carrier 205, and UE 115-a can send uplink communication to base station 105-a via uplink carrier 210. While this example illustrates a single downlink carrier 205 and a single uplink carrier 210, in other cases, UE 115-a can be configured for carrier aggregation and use multiple uplink or downlink carriers. Furthermore, although the various examples discussed herein refer to communication with a single base station 105-a, the techniques discussed herein can be applied to situations where different base stations 105-a or multiple TRPs associated with a base station provide communication with UE 115-a.

[0089] In some cases, UE 115-a may send a capability indication 215 to base station 105-a, indicating that UE 115-a has the capability to perform blind decoding limit adjustments. Base station 105-a may send a configuration message 220 to UE 115-a, which may configure one or more conditions that will trigger adjustments to the blind decoding limits at UE 115-a. In some cases, configuration message 220 may be sent in response to capability indication 215, and in other cases, configuration message 220 may be sent regardless of whether UE 115-a sends capability indication 215 or based on one or more other parameters implicitly indicating that UE 115-a is capable of adjusting blind decoding limits. Based on the blind decoding limits, base station 105-a may select one or more PDCCH resources for transmission of PDCCH communication 225, and may use a blind decoding procedure at UE 115-a to receive the transmission of PDCCH communication 225.

[0090] In some cases, configuration message 220 can provide information for one or more blind decoding limit adjustment trigger conditions 230. In such cases, base station 105-a can use blind decoding limit adjustment trigger condition 230-a, and UE 115-a can use blind decoding limit adjustment trigger condition 230-b. UE 115-a and base station 105-a can use nominal blind decoding limits even if blind decoding limit adjustment trigger condition 230 is not met, and can perform adjustments to the blind decoding limits if one or more of the trigger conditions 230 are met. (Refer to...) Figures 3 to 5 Various examples of adjustments to blind decoding constraints are discussed in more detail. When transmitting PDCCH communication 225, base station 105-a can select PDCCH resources within a configured search space based on whether the nominal blind decoding constraint or the adjusted blind decoding constraint is being used, thereby performing PDCCH resource selection 235 based on the current blind decoding constraint. Similarly, UE 115-a can perform PDCCH candidate identification 240 based on the current blind decoding constraint.

[0091] The nominal or adjusted blind decoding limit allows base station 105-a to maintain the scheduling flexibility for efficient PDCCH communication with multiple UEs 115, while also providing reduced processing overhead and power consumption at UE 115-a when trigger conditions are met. In some cases, multiple different trigger conditions can be configured, and a specific blind decoding limit can be triggered when one or a combination of different trigger conditions is met. In some cases, one or more different trigger conditions can be configured, including trigger conditions based on: the BWP used for communication, the beam used for communication, the time slot for communication, whether a dynamic or UE-requested CORESET is associated with communication, whether the DCI is carried in the same time slot, or any combination thereof. In some cases, the blind decoding limit can be adjusted when any of the configured trigger conditions is met. In other cases, a combination of different trigger conditions can be used to initiate blind decoding limit adjustments. Therefore, based on whether the configured triggering constraint conditions are met, the specific blind decoding constraint for the search space can be a baseline blind decoding constraint (e.g., an unadjusted blind decoding constraint as a predefined constraint), a reduced blind decoding constraint (e.g., an adjustment to the baseline blind decoding constraint, such as a 50% reduction), or an increased blind decoding constraint (e.g., an adjustment to the baseline blind decoding constraint, such as a 25% increase, which provides additional scheduling flexibility for the scheduler at base station 105-a). In some cases, the specific blind decoding constraint can be jointly configured with the condition configuration in configuration message 220. In other cases, the DCI can indicate the specific blind decoding constraint for one or more indicated time slots. Additionally or alternatively, base station 105-a can define one or more rules in RRC signaling, and UE 115-a can determine the specific blind decoding constraint based on the triggering conditions and the rules.

[0092] In some cases, capability indication 215 may include bits or information elements indicating whether condition-based blind decoding constraint adjustment is supported at UE 115-a. In some cases, one or more bits or elements may be used to indicate (e.g., in configuration message 220) which conditions are configured for condition-based blind decoding constraint adjustment (e.g., only one condition, multiple conditions, or one or more combinations of multiple conditions). In some cases, this capability may be associated with the type of UE 115-a (e.g., a lower-layer UE may support condition-based blind decoding BD constraint adjustment).

[0093] Figure 3Examples of bandwidth-partial triggering conditions supporting blind decoding limiting techniques for wireless communication according to various aspects of this disclosure are shown. In some examples, wireless communication system 300 may implement aspects of wireless communication system 100 or 200. Wireless communication system 300 may include base station 105-b and UE 115-b, which may respectively refer to Figure 1 or Figure 2 Examples of base station 105 and UE 115 are described.

[0094] In this example, base station 105-b and UE 115-b can communicate using communication link 305. In some cases, communication link 305 can use one of multiple available BWPs, and base station 105-b can configure blind decoding restriction triggering conditions based on which BWP will be used for communication. For example, a first BWP 310 can be associated with a nominal or baseline blind decoding restriction, and a second BWP 315 can be associated with an adjusted blind decoding restriction. If UE 115-b receives an indication to switch to the second BWP 315, the BWP handover can trigger blind decoding restriction triggering, and UE 115-b can adjust the blind decoding restriction.

[0095] In some cases, base station 105-b can configure different blind decoding limits for different BWPs based on the number of UEs on certain BWPs. For example, the first BWP 310 may have a relatively large number of UEs 115, and the second BWP 315 may have a relatively small number of UEs 115, allowing the blind decoding limit to be adjusted downwards without risking a significant increase in PDCCH congestion. For example, UE 115-b may switch to the first BWP 310 (where more UEs 115 are scheduled), and to provide scheduling flexibility, the blind decoding limit should be a large value (e.g., the baseline configuration, or an increased blind decoding limit). If UE 115-b switches to the second BWP 315 (where fewer UEs 115 are scheduled), the reduced blind decoding limit can be configured to save UE 115-b power. If UE 115-b switches to the second BWP 315 (where fewer CCEs or a lower aggregation level are configured), a reduced blind decoding limit can be configured. Additionally or alternatively, if UE 115-b switches to the second BWP 315 (where a smaller CORSET size or good link performance / coverage exists), a reduced blind decoding limit can be configured. Furthermore, in some cases, if UE 115-b switches to the second BWP 315 (where low data rate traffic exists (e.g., which may be associated with relaxed latency requirements)), the blind decoding limit can be reduced without sacrificing scheduling flexibility.

[0096] In some cases, different BWPs can be configured with specific blind decoding restrictions, and these restrictions can be triggered by BWP handover. In some cases, specific blind decoding restrictions can be combined with BWP configurations in RRC signaling. In other cases, specific blind decoding restrictions can be indicated by a DCI used for different BWP configurations (e.g., in another DCI or in the DCI indicating BWP handover).

[0097] Figure 4 Examples of Transmission Configuration Indicator (TCI) triggering conditions supporting blind decoding restriction techniques for wireless communication are shown according to various aspects of this disclosure. In some examples, wireless communication system 400 may implement aspects of wireless communication systems 100, 200, or 300. Wireless communication system 400 may include base station 105-c and UE 115-c, which may respectively refer to Figures 1 to 3 Examples of base station 105 and UE 115 are described.

[0098] In this example, base station 105-c and UE 115-c can communicate using beamforming communication, where a first beam 405 and a second beam 410 can be used for communication. In some cases, the first beam 405 can be associated with a first TCI state, and the second beam 410 can be associated with a second TCI state. In some cases, base station 105-c can configure blind decoding restriction triggering conditions based on which beam is to be used for communication. For example, a nominal blind decoding restriction 415 can be associated with the first beam 405, and an adjusted blind decoding restriction 420 can be associated with the second beam 410. When UE 115-c receives an indication to switch to the second beam 410, beam switching can trigger blind decoding restriction triggering, and UE 115-c can adjust the blind decoding restriction.

[0099] Regarding Figure 3Similar to what is discussed in BWP, in some cases, base station 105-c can configure different blind decoding limits for different beams based on the number of UEs using a specific TCI state. For example, if UE 115-c is configured with a second beam 410 (where fewer UEs 115 are scheduled), the adjusted blind decoding limit 420 can provide a reduced number of blind decoding candidates and can be configured to save UE 115-c power. In other cases, if UE 115-c is configured with a second beam 410 with good link performance / coverage, the adjusted blind decoding limit 420 can provide a reduced number of blind decoding candidates and can be configured to save UE 115-c power. In some cases, different TCI states can be configured with specific blind decoding limits, which can provide reduced or increased blind decoding limits corresponding to different conditions. Specific blind decoding limits can be triggered by TCI state (e.g., beam) updates. In some cases, specific blind decoding limits are combined with TCI state configurations in RRC signaling. In other cases, specific blind decoding limitations can be indicated by a DCI used for different TCI state configurations. Such a DCI can be a scheduling DCI that includes the TCI state configuration, or it can be another DCI.

[0100] Figure 5 Examples of pattern-based triggering conditions supporting blind decoding restriction techniques for wireless communication are shown according to various aspects of this disclosure. In some examples, wireless communication system 500 may implement aspects of wireless communication systems 100, 200, 300, or 400. Wireless communication system 500 may include base station 105-d and UE 115-d, which may respectively refer to... Figures 1 to 4 Examples of base station 105 and UE 115 are described.

[0101] In this example, base station 105-d and UE 115-d can communicate using communication link 505, and blind decoding limit adjustments can be performed based on a periodic pattern. In some cases, this pattern can be based on the time slot location of the PDCCH, and a first time slot subset 510 can have a nominal blind decoding limit, while a second time slot subset 515 can have an adjusted blind decoding limit. In some cases, pattern-based blind decoding limits can be configured via RRC signaling. Such techniques allow blind decoding limits to be adjusted based on existing periodic conditions. For example, UE 115-d can be a stationary UE 115-d (e.g., used for video surveillance or industrial sensors) and may experience periodic blocking rate variations due to other UEs communicating with base station 105-d according to a periodic pattern. In some cases where UE 115-d experiences poor link performance during periodic time slots, the baseline of the blind decoding limit can be configured to ensure an acceptable blocking rate. In some modes, reduced blind decoding limits can be triggered when UE 115-d experiences stable and good link performance during other periodic time slots. In some cases, multiple different modes can be configured with specific blind decoding limits. Specific blind decoding limits can follow a periodic pattern; for example, the second time slot subset 515 has reduced blind decoding limits, and the first time slot subset 510 has baseline blind decoding limits. Specific blind decoding limits can be triggered by mode configuration (e.g., periodicity) or by UE type (e.g., video surveillance UE). In some cases, specific blind decoding limits are combined with modes configured by RRC signaling. Optionally, DCI can be used to activate and deactivate mode-related blind decoding limits. If the mode is deactivated, UE 115-d can assume baseline blind decoding limits.

[0102] Additionally or alternatively, blind decoding restrictions can be adjusted based on the type of CORESET associated with the PDCCH. In some cases, UE 115-d can be configured with different specific blind decoding restrictions for dynamic CORESETs or search spaces. In some cases, for dynamic CORESETs or search spaces, the search space can be scheduled (enabled) by another DCI from another search space. For example, when a dynamic CORESET or SS is triggered, it may have reduced blind decoding restrictions. Specific blind decoding restrictions can be configured by another DCI from another search space and can be triggered by a type CORESET or search space. In other cases, the CORESET or search space requested by the UE can be configured with different specific blind decoding restrictions. For example, if UE 115-d requests a CORESET or search space, specific blind decoding restrictions can be configured for that request. In some cases, specific blind decoding restrictions are associated with the requested CORESET or search space, which can be pre-configured in RRC signaling, or the blind decoding restrictions can be dynamically configured in the DCI.

[0103] In another example, blind decoding constraint adjustment can be triggered based on whether a time slot is configured to carry DCI (i.e., DCI is multiplexed with Physical Downlink Shared Channel (PDSCH) communication). For example, a first DCI portion can be transmitted within the PDCCH and can include information indicating the size of a second DCI portion transmitted within the PDSCH. If the PDCCH and the DCI are in the same time slot, it can satisfy blind decoding constraint adjustment triggering conditions indicating the presence of a specific blind decoding constraint. In some cases, reduced blind decoding constraints for carrying DCI can be indicated by a first DCI within the PDCCH in the same time slot. In other cases, reduced blind decoding constraints for carrying DCI can be indicated by another DCI in a different time slot. In some cases, if a time slot is configured to carry DCI, specific blind decoding constraints may exist in the time slot, which can be indicated by another DCI, RRC signaling, in combination with the carrying configuration, in MAC-CE, or any combination thereof.

[0104] Figure 6 Examples of a processing flow 600 supporting blind decoding restriction techniques for wireless communication according to various aspects of this disclosure are shown. In some examples, processing flow 600 may implement various aspects of wireless communication systems 100 to 500. Processing flow 600 may be implemented by a UE 115-e and a base station 105-e (which may be examples of UEs and base stations as described herein). Alternative examples are possible, some of which may be performed in a different order than described or not at all. In some cases, steps may include additional features not mentioned below, or further steps may be added.

[0105] At point 605, UE 115-e can send a UE capability indication to base station 105-e. The UE capability indication can provide information such as the UE 115-e's ability to perform adjustments to blind decoding restrictions. In some cases, the UE 115-e capability indication can be provided during initial access. In other cases, the UE capability indication can be provided in response to the reconfiguration of one or more parameters. The UE capability indication can be sent in MAC-CE, UCI, RRC signaling, or any combination thereof.

[0106] At 610, base station 105-e can configure blind decoding restrictions and triggers for adjusting the blind decoding restrictions. In some cases, the blind decoding restrictions can be configured to provide adjustments to the blind decoding restrictions upon satisfaction of one or more triggering restrictions. At 615, base station 105-e can send configuration information to UE 115-e indicating the blind decoding restrictions and one or more triggering conditions for adjusting the blind decoding restrictions. In some cases, the configuration information can be provided via RRC signaling, via one or more DCIs, in one or more MAC CEs, or any combination thereof. At 620, UE 115-e can identify the blind decoding restrictions and trigger adjustments to the blind decoding restrictions. The blind decoding restrictions and the conditions for triggering their adjustment can be identified according to techniques as discussed herein.

[0107] At point 625, the operations associated with the case where blind decoding constraint triggering is not met are discussed. The determination of whether one or more blind decoding constraint triggering is met can be performed according to the techniques discussed herein. In such a case, at point 630, base station 105-e can select PDCCH resources based on the nominal blind decoding constraint. In some cases, the nominal blind decoding constraint can be determined based on the established techniques, such as the aggregation level, the number of CCEs, the search space for PDCCH, the configured PDCCH candidates for each time slot, etc. At point 635, base station 105-e can use the selected PDCCH resources to send PDCCH to UE 115-e. At point 640, UE 115-e can perform blind decoding based on the nominal number of blind decoding candidates and the nominal blind decoding constraint.

[0108] At 645, operations associated with the condition where a blind decoding constraint trigger is met are discussed. The determination of whether one or more blind decoding constraint triggers are met can be performed according to the techniques discussed herein. In such a case, base station 105-e and UE 115-e can determine that the blind detection constraint trigger condition is met. Such determination can be based on, for example, the BWP used for PDCCH transmission, the beam used for PDCCH transmission, the periodicity pattern, the CORESET or search space for PDCCH transmission, whether the time slot with PDCCH is configured to carry DCI, or any combination thereof, as discussed herein. At 655, base station 105-e can select PDCCH resources based on an adjusted blind decoding constraint, which can be increased or decreased relative to the nominal blind decoding constraint. At 660, base station 105-e can send PDCCH to UE 115-e using the selected PDCCH resources. At 665, UE 115-e can perform blind decoding based on an adjusted number of blind decoding candidates and an adjusted blind decoding constraint, as discussed herein.

[0132] I / O controller 1010 can manage input and output signals for device 1005. I / O controller 1010 can also manage peripheral devices not integrated into device 1005. In some cases, I / O controller 1010 can represent a physical connection or port to an external peripheral device. In some cases, I / O controller 1010 can utilize, for example...

For example, device 1005 or components of device 1005 may include processor 1040 and memory 1030 coupled to processor 1040, processor 1040 and memory 1030 being configured to perform the various functions described herein.

[0136] According to the examples disclosed herein, the communication manager 1020 can support wireless communication at the UE. For example, the communication manager 1020 can be configured or otherwise supported to include elements for sending an instruction to the base station regarding support for blind decoding limit adjustment at the UE. The communication manager 1020 can be configured or otherwise supported to receive from the base station trigger conditions for adjusting a first blind decoding limit from a first number of blind decoding candidates to be monitored for control channel communications from the base station to a second number of blind decoding candidates to be monitored for control channel communications.

[0137] By including or configuring the communication manager 1020 according to the examples described herein, the device 1005 can support techniques for reducing the number of blind decoding operations performed at the device 1005, which can provide, for example, improved communication reliability, reduced latency, improved user experience associated with reduced processing, reduced power consumption, more efficient use of communication resources, longer battery life, improved use of processing power, or a combination thereof.

[0138] In some examples, the communication manager 1020 may be configured to perform various operations (e.g., receive, monitor, transmit) using or in cooperation with transceiver 1015, one or more antennas 1025, or any combination thereof. Although the communication manager 1020 is shown as a separate component, in some examples, one or more functions described with reference to the communication manager 1020 may be supported or performed by processor 1040, memory 1030, code 1035, or any combination thereof.
