Background of the Invention

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

[0004] The described techniques relate to improved methods, systems, devices, and apparatuses that support priority-based search space classification. Generally, the described techniques enable a user equipment (UE) to send an indication of one or more channels that the UE is capable of supporting at a first priority and one or more channels at a second priority, where the first priority is higher than the second priority. The UE may receive signaling indicating a set of search spaces within a control resource set (CORESET), where the first set of search spaces corresponds to grant candidates for scheduling one or more channels at the first priority. The UE may determine a second set of search spaces within the CORESET, where the second set of search spaces corresponds to grant candidates for scheduling one or more channels at the second priority. The UE may decode grants for scheduling one or more channels at the first priority within the search space of the first set of search spaces. Additionally, the UE may decode grants for scheduling one or more channels at the second priority within a second search space of the first set of search spaces or within the search space of the second set of search spaces.

[0041] In some cases, a user equipment (UE) may receive downlink control information (DCI) in a control resource set (CORESET) via one or more control channel elements (CCE). The DCI may include a ultra-reliable low-latency communication (URLLC) grant that schedules a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH) transmission associated with URLLC traffic. Alternatively, the DCI may include an enhanced mobile broadband (eMBB) grant that schedules a PDSCH or a PUSCH transmission associated with eMBB traffic.

[0042] The UE may receive a downlink grant that schedules a data transmission (e.g., a PDSCH transmission or a PUSCH transmission) in a CORESET on one or more CCEs. The grant may be a ultra-reliable low-latency communication (URLLC) grant or may be an eMBB grant. In some cases, the UE may receive multiple grants in a single CORESET. For example, the UE may receive an eMBB grant via a first set of CCEs within the CORESET and may receive a URLLC grant via a second set of CCEs within the CORESET.

[0043] To detect where a grant may be located within a CORESET, the UE may perform blind decoding (BD) on some or each search space in a search space set. Each search space may span a different set of CCEs of the CORESET. In the case where the UE receives multiple grants within a single CORESET and the size of the DCI associated with each grant is the same, the UE may perform BD on grant candidates at an aggregation level L in any search space set. This case may be referred to as search space sharing.

[0044] Generally, if the UE 115 can support two component carriers (CCs) in the downlink, uplink, or both, the UE 115 can perform twice the number of BDs equivalent to two CCs for a single CC. For the case where the UE decodes URLLC grants and eMBB grants within a single CC, compared to processing data transmission associated with one of the grants, the UE can use twice the processing capacity to process data transmission associated with these two grants. However, for the case where the UE decodes a URLLC grant on one CC and an eMBB grant on another CC, compared to processing data transmission associated with one grant on a single CC, the UE can use less than twice the processing capacity to process data transmission associated with these two grants. The UE can use less than twice the processing capacity because some blocks for data processing can be shared between the two CCs. Therefore, compared to processing data transmission associated with two grants in two CCs, the UE may take longer to process data transmission associated with two grants in one CC.

[0045] In some cases, the UE can successfully decode two grants within a threshold number of BDs starting from the last executed BD. If the UE has decoded one grant in one CC and one grant in another CC, the UE may have enough time to process the corresponding data transmissions within a given time constraint (e.g., before the resources for sending feedback via the physical uplink control channel (PUCCH) have elapsed). However, since the UE decodes two grants within a single CC, the UE may take longer to process the corresponding data transmissions and may exceed the given time constraint.

[0046] To enable the UE to have enough time to process two data transmissions, the UE can divide the search space set into a first subset through which the UE can decode one or two grants and a second subset through which the UE can decode one grant rather than two grants. The UE can first perform the BDs of the first subset and can perform the BDs of the second subset after performing the BDs of the first subset. Thus, if the UE fails to decode any grant when performing the BDs of the first subset, the UE can decode no more than one grant in the second subset. Therefore, when two grants are within the CORESET, the UE can decode two grants in the first subset and has at least the time used by the UE to perform the BDs of the second subset to process these two grants. Alternatively, the UE can decode one grant in the first subset and another grant in the other subset and can at least partially process data transmission associated with the grant decoded in the first subset before processing data transmission associated with the grant decoded in the second subset.

[0047] The UE can decode which grant in any subset (e.g., the first or second subset), and which grant the UE can decode in a subset (e.g., the first subset) may depend on the priority associated with each grant. For example, if one of the grants is associated with a channel (e.g., URLLC PUSCH or URLLC PDSCH) that has a higher priority than the channel of another grant (e.g., eMBB PUSCH or eMBB PDSCH), the higher-priority grant can be decoded in the first subset, and the lower-priority grant can be decoded in the first subset or the second subset. In one example, the URLLC grant may have a higher priority than the eMBB grant. Thus, the URLLC grant can be decoded in the first subset but not the second subset, and the eMBB grant can be decoded in the first or second subset. Alternatively, the eMBB grant can be decoded in the second subset but not the first subset.

[0048] Aspects of the present disclosure are initially described in the context of a wireless communication system. Additional aspects of the present disclosure are described in the context of additional wireless communication systems, BD orders, priority-based BD procedures, and process flows. Aspects of the present disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts related to priority-based search space classification.

[0049] Figure 1 An example of a wireless communication system 100 that supports priority-based search space classification in accordance with aspects of the present disclosure is shown. The wireless communication system 100 includes a base station 105, a UE 115, and a core network 130. In some examples, the wireless communication system 100 can 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 cases, the wireless communication system 100 can support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, or communication with low-cost and low-complexity devices.

[0050] Base station 105 may communicate wirelessly with UE 115 via one or more base station antennas. The base station 105 described herein may include or may be referred to by those skilled in the art as a base station transceiver, radio base station, access point, radio transceiver, NodeB, eNodeB (eNB), next-generation NodeB, or giga-NodeB (any of which may be referred to as a gNB), home NodeB, home eNodeB, or some other suitable term. The wireless communication system 100 may include different types of base stations 105 (e.g., macro cell base stations or small cell base stations). The UE 115 described herein is capable of communicating with various types of base stations 105 and network devices, including macro eNBs, small cell eNBs, gNBs, relay base stations, and the like.

[0051] Each base station 105 may be associated with a particular geographic coverage area 110 in which communication with various UEs 115 is supported. Each base station 105 may provide communication coverage for the corresponding geographic coverage area 110 via a communication link 125, and the communication link 125 between the base station 105 and the UE 115 may utilize one or more carriers. The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105 or a downlink transmission from the base station 105 to the UE 115. The downlink transmission may also be referred to as a forward link transmission, and the uplink transmission may also be referred to as a reverse link transmission.

[0052] The geographic coverage area 110 of the base station 105 may be divided into sectors that form part of the geographic coverage area 110, and each sector may be associated with a cell. For example, each base station 105 may provide communication coverage for a macro cell, small cell, hot spot, or other type of cell or various combinations thereof. In some examples, the base station 105 may be mobile and thus provide communication coverage for a mobile geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap and may be supported by the same base station 105 or different base stations 105 for the overlapping geographic coverage areas 110 associated with different technologies. The wireless communication system 100 may include, for example, a heterogeneous LTE / LTE-A / LTE-A Pro or NR network, where different types of base stations 105 provide coverage for respective geographic coverage areas 110.

[0053] The term "cell" refers to a logical communication entity for communication with base station 105 (e.g., via a carrier), and can be associated with an identifier (e.g., physical cell identifier (PCID), virtual cell identifier (VCID)) for differentiating adjacent cells operating via the same carrier or different carriers. In some examples, a carrier can support multiple cells, and different cells can be configured according to different protocol types (e.g., machine type communication (MTC), narrowband Internet of Things (NB-IoT), enhanced mobile broadband (eMBB), etc.) that can provide access for different types of devices. In some cases, the term "cell" can refer to a part (e.g., a sector) of the geographical coverage area 110 over which the logical entity operates.

[0054] UEs 115 can be dispersed throughout the wireless communication system 100, and each UE 115 can be fixed or mobile. UE 115 can also be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, where "device" can also be referred to as a unit, station, terminal, or client. UE 115 can also be 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 can also refer to a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or MTC device, etc., which can be implemented in various items such as appliances, vehicles, meters, etc.

[0055] Some UEs 115 (such as MTC or IoT devices) can be low-cost or low-complexity devices, and can provide automatic communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to a data communication technology that allows 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 integrated with sensors or meters to measure or capture information and relay the information to a central server or application, which can utilize the information or present the information to a human interacting with the program or application. Some UEs 115 can be designed to collect information or implement automatic behavior of machines. Application examples of MTC devices include smart metering, inventory monitoring, water level monitoring, device monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business billing.

[0056] Some UEs 115 may be configured to operate in power consumption reduction modes, such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception, but not simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power saving techniques of the UE 115 include entering a power saving “deep sleep” mode when not participating in active communication, or operating on limited bandwidth (e.g., according to narrowband communication). In some cases, the UE 115 may be designed to support critical functions (e.g., mission-critical functions), and the wireless communication system 100 may be configured to provide ultra-reliable communication for these functions.

[0057] In some cases, the UE 115 is also capable of communicating directly with other UEs 115 (e.g., using peer-to-peer (P2P) or device-to-device (D2D) protocols). One or more of the UEs 115 in a group utilizing D2D communication may be within the geographical coverage area 110 of the base station 105. Other UEs 115 in this group may be outside the geographical coverage area 110 of the base station 105, or may not be able to receive transmissions from the base station 105 for other reasons. In some cases, a group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, where each UE 115 transmits to each other UE 115 in the group. In some cases, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without the participation of the base station 105.

[0058] The base stations 105 may communicate with the core network 130 and with each other. For example, the base stations 105 may interface with the core network 130 via a backhaul link 132 (e.g., via S1, N2, N3, or other interfaces). The base stations 105 may communicate with each other directly (e.g., directly between base stations 105) or indirectly (e.g., via the core network 130) via a backhaul link 134 (e.g., via X2, Xn, or other interfaces).

[0059] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC), which may include at least one mobility management entity (MME), at least one serving gateway (S-GW), and at least one packet data network (PDN) gateway (P-GW). The MME may manage non-access stratum (e.g., control plane) functions such as mobility, authentication, and bearer management for UEs 115 served by base stations 105 associated with the EPC. User IP packets may be transported through the S-GW, which may itself be connected to the P-GW. The P-GW may provide IP address allocation and other functions. The P-GW may be connected to network operator IP services. The operator IP services may include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or packet-switched (PS) streaming services.

[0060] At least some of the network devices (such as base station 105) may include subcomponents (such as access network entities), which may be examples of access node controllers (ANCs). Each access network entity may communicate with a UE 115 through a plurality of other access network transmission entities, which may be referred to as radio heads, intelligent radio heads, or transmit / receive points (TRPs). In some configurations, the various functions of each access network entity or base station 105 may be distributed across various network devices (such as radio heads and access network controllers) or consolidated into a single network device (such as base station 105).

[0061] The wireless communication system 100 may operate using one or more frequency bands such as in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, since the wavelengths are in the range of approximately one decimeter to one meter long, the region of 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band. UHF waves may be blocked or redirected by buildings and environmental features. However, the waves may penetrate structures sufficiently to enable a macro cell to serve UEs 115 located indoors. Compared to transmissions using lower frequencies and longer waves in the spectrum below 300 MHz in the high frequency (HF) or very high frequency (VHF) portions, transmissions of UHF waves may be associated with smaller antennas and shorter distances (e.g., less than 100 km).

[0062] The wireless communication system 100 may also operate in the super-high frequency (SHF) region using a frequency band of 3 GHz to 30 GHz (also known as the centimeter band). The SHF region includes frequency bands such as the industrial, scientific, and medical (ISM) band at 5 GHz, which may be opportunistically used by devices that can tolerate interference from other users.

[0063] The wireless communication system 100 may also operate in the extremely high frequency (EHF) region of the spectrum (e.g., 30 GHz to 300 GHz), which is also known as the millimeter wave band. In some examples, the wireless communication system 100 may support millimeter wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the respective devices may be even smaller and more closely spaced than UHF antennas. In some cases, this may facilitate the use of antenna arrays within the UE 115. However, the propagation of EHF transmissions may suffer even greater atmospheric attenuation and shorter distances than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions using one or more different frequency regions, and the specified use of frequency bands across these frequency regions may vary by country or regulatory body.

[0064] In some cases, the wireless communication system 100 may utilize licensed radio spectrum bands and unlicensed radio spectrum bands. For example, the wireless communication system 100 may use licensed-assisted access (LAA), LTE-unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band such as the 5 GHz ISM band. When operating in an unlicensed radio spectrum band, wireless devices such as the base station 105 and the UE 115 may employ a listen-before-talk (LBT) procedure to ensure that the channel is idle before transmitting data. In some cases, operation in the unlicensed band may be based on a carrier aggregation configuration in combination with a component carrier operating in a licensed band (e.g., LAA). Operation in the unlicensed spectrum may include downlink transmissions, uplink transmissions, peer-to-peer transmissions, or a combination of these. Duplexing in the unlicensed spectrum may be based on frequency-division duplexing (FDD), time-division duplexing (TDD), or a combination of both.

[0065] In some examples, the base station 105 or the UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. For example, the wireless communication system 100 may use a transmission scheme between a transmitting device (e.g., the base station 105) and a receiving device (e.g., the UE 115), where the transmitting device is equipped with multiple antennas and the receiving device is equipped with one or more antennas. MIMO communication can increase spectral efficiency by using multipath signal propagation to transmit or receive multiple signals via different spatial layers, which may be referred to as spatial multiplexing. The multiple signals may be transmitted, for example, by the transmitting device via different antennas or different combinations of antennas. Similarly, the 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. Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) in which multiple spatial layers are transmitted to the same receiving device, and multi-user MIMO (MU-MIMO) in which multiple spatial layers are transmitted to multiple devices.

[0066] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., the base station 105 or the UE 115) to shape and steer an antenna beam (e.g., a transmit or receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals transmitted via the antenna elements of an antenna array such that signals propagating in a particular azimuth relative to the antenna array experience constructive interference while other signals experience destructive interference. The adjustment of the signals transmitted via the antenna elements may include the transmitting device or the receiving device applying an amplitude and phase offset to the signals carried by each of the antenna elements associated with the device. The adjustment associated with each of the antenna elements may be defined by a set of beamforming weights associated with a particular azimuth (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other azimuth).

[0067] In one example, base station 105 may use multiple antennas or antenna arrays to perform beamforming operations for directional communication with UE 115. For example, 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, which may include signals transmitted according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions may be used to identify (e.g., by base station 105 or a receiving device such as UE 115) the beam direction for subsequent transmission or reception by base station 105.

[0068] 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 a receiving device such as UE 115). In some examples, the beam direction associated with a transmission in a single beam direction may be determined at least in part based on signals transmitted in different beam directions. For example, UE 115 may receive one or more of the signals transmitted by base station 105 in different directions, and UE 115 may report to base station 105 an indication of the signal that it received with the highest signal quality or otherwise acceptable signal quality. 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 sending data to a receiving device).

[0069] When receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105, a receiving device (e.g., UE 115, which can be an example of a mmW receiving device) can attempt multiple receive beams. For example, the receiving device can attempt multiple receive directions in the following ways: receive via different antenna sub-arrays; process the received signals according to different antenna sub-arrays; receive according to different receive beamforming weight sets applied to the signals received at multiple antenna elements of the antenna array; or process the received signals according to different receive beamforming weight sets applied to the signals received at multiple antenna elements of the antenna array, any of which can be referred to as "listening" according to different receive beams or receive directions. In some examples, the receiving device can use a single receive beam to receive along a single beam direction (e.g., when receiving a data signal). The single receive beam can be aligned in a beam direction determined at least in part based on listening according to different receive beam directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio, or otherwise acceptable signal quality based at least in part on listening according to multiple beam directions).

[0070] In some cases, the antennas of base station 105 or UE 115 can be located within one or more antenna arrays, which can support MIMO operations, or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays can be co-located at an antenna assembly, such as an antenna tower. In some cases, the antennas or antenna arrays associated with base station 105 can be located at different geographical locations. Base station 105 can have an antenna array with multiple rows and columns of antenna ports, and base station 105 can use this antenna array to support beamforming for communication with UE 115. Similarly, UE 115 can have one or more antenna arrays that can support various MIMO or beamforming operations.

[0071] In some cases, wireless communication system 100 can be a packet-based network operating according to a hierarchical protocol stack. In the user plane, the communication at the bearer or packet data convergence protocol (PDCP) layer can be IP-based. The radio link control (RLC) layer can perform data packet segmentation and reassembly for communication via logical channels. The medium access control (MAC) layer can perform priority handling and multiplex logical channels into transport channels. The MAC layer can also use hybrid automatic repeat request (HARQ) to provide 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 an RRC connection between UE 115 and base station 105 or core network 130 that supports the radio bearers for user plane data. At the physical layer, the transport channels can be mapped to physical channels.

[0072] In some cases, the UE 115 and the base station 105 may support retransmission of data to increase the likelihood of successfully receiving the data. HARQ feedback is a technique for increasing the likelihood of correctly receiving data via the 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 throughput at the MAC layer under poor radio conditions (e.g., signal-to-noise ratio conditions). In some cases, a wireless device may support HARQ feedback for the same time slot, where the device may provide HARQ feedback for data received in previous symbols in that time slot. In other cases, the device may provide HARQ feedback in a subsequent time slot or according to some other time interval.

[0073] Time intervals in LTE or NR can be expressed as multiples of a basic time unit, which may refer to, for example, the sampling period T s = 1 / 30,720,000 seconds. The time intervals of communication resources can be organized according to radio frames each having a duration of 10 milliseconds (ms), where the frame period can be expressed as T f = 307,200T s . Radio frames can be identified by a system frame number (SFN) in the range from 0 to 1023. Each frame can include 10 subframes numbered from 0 to 9, and the duration of each subframe is 1 ms. A subframe can also be divided into 2 time slots, each having a duration of 0.5 ms, and each time slot can contain 6 or 7 modulation symbol periods (e.g., depending on the length of the cyclic prefix preceding each symbol period). Excluding the cyclic prefix, each symbol period can contain 2048 sampling periods. In some cases, a subframe can be the smallest scheduling unit of the wireless communication system 100 and can be referred to as a transmission time interval (TTI). In other cases, the smallest scheduling unit of the wireless communication system 100 can be shorter than a subframe or can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs) or in a selected component carrier using sTTIs).

[0074] In some wireless communication systems, a time slot can also be divided into multiple mini-slots each containing one or more symbols. In some cases, the symbols or mini-slots of a mini-slot can be the smallest unit of scheduling. For example, the duration of each symbol can vary, depending on, for example, the subcarrier spacing or frequency band of operation. Additionally, some wireless communication systems can implement time slot aggregation, where multiple time slots or mini-slots are aggregated together and used for communication between the UE 115 and the base station 105.

[0075] The term "carrier" refers to a set of radio spectrum resources that has a defined physical layer structure for supporting communication on communication link 125. For example, a carrier of communication link 125 can include a portion of a radio spectrum band that operates according to the physical layer channels for a given radio access technology. Each physical layer channel can carry user data, control information, or other signaling. A carrier can be associated with a predefined frequency channel (e.g., an evolved universal mobile telecommunications system terrestrial radio access (E-UTRA) absolute radio frequency channel number (EARFCN)) and can be positioned according to a channel grid for discovery by UE 115. A carrier can be downlink or uplink (e.g., in FDD mode) or be configured to carry both downlink and uplink communications (e.g., in TDD mode). In some examples, the signal waveform transmitted on a carrier can be composed of multiple subcarriers (e.g., using a multi-carrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)).

[0076] For different radio access technologies (e.g., LTE, LTE-A, LTE-A Pro, NR), the organizational structure of a carrier can be different. For example, the communication on a carrier can be organized according to a transmission time interval (TTI) or a time slot, each of which can include user data as well as control information or signaling to support decoding of the user data. A carrier can also include dedicated acquisition signaling (e.g., synchronization signals or system information, etc.) and control signaling for coordinating the operation of the carrier. In some examples (e.g., in a carrier aggregation configuration), a carrier can also have acquisition signaling or control signaling for coordinating the operation of other carriers.

[0077] Physical channels can be multiplexed on a carrier according to various techniques. Physical control channels and physical data channels can be multiplexed on a downlink carrier using, for example, time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. In some examples, the control information transmitted in a physical control channel can be distributed in a cascaded manner between different control regions (e.g., between a common control region or a common search space and one or more UE-specific control regions or UE-specific search spaces).

[0078] A carrier can be associated with a specific bandwidth of the radio spectrum, and in some examples, the carrier bandwidth can be referred to as the "system bandwidth" of the carrier or the wireless communication system 100. For example, the carrier bandwidth can be one of a plurality of predetermined bandwidths of a carrier for a particular radio access technology (e.g., 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz). In some examples, each served UE 115 can be configured to operate on a portion or all of the carrier bandwidth. In other examples, some UEs 115 can be configured to operate using a narrowband protocol type associated with a predefined portion or range (e.g., a set of subcarriers or RBs) within the carrier (e.g., "in-band" deployment of the narrowband protocol type).

[0079] In a system employing MCM technology, a resource element can include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and the 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). Thus, the more resource elements received by the UE 115 and the higher the order of the modulation scheme, the higher the data rate can be for the UE 115. In an MIMO system, the wireless communication resources can refer to a combination of radio spectrum resources, time resources, and spatial resources (e.g., spatial layers), and the use of multiple spatial layers can further increase the data rate for communicating with the UE 115.

[0080] Devices of the wireless communication system 100 (e.g., the base station 105 or the UE 115) can have a hardware configuration that supports communication on a specific carrier bandwidth, or can be configured to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 can include the base station 105, the UE 115, or both that support simultaneous communication via carriers associated with more than one different carrier bandwidth.

[0081] The wireless communication system 100 can support communication with the UE 115 on multiple cells or carriers, which is a feature that can be referred to as carrier aggregation or multi-carrier operation. According to the carrier aggregation configuration, the UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used for both FDD and TDD component carriers.

[0082] In some cases, the wireless communication system 100 may utilize an enhanced component carrier (eCC). The eCC may be characterized by one or more features including a wider carrier or frequency channel bandwidth, a shorter symbol duration, a shorter TTI duration, or a modified control channel configuration. In some cases, the eCC may be associated with a carrier aggregation configuration or a dual connectivity configuration (e.g., when multiple serving cells have sub-optimal or non-ideal backhaul links). The eCC may also be configured to operate in unlicensed spectrum or shared spectrum (e.g., allowing more than one operator to use the spectrum). The eCC characterized by a wide carrier bandwidth may include one or more segments that may be utilized by a UE 115 that cannot monitor the entire carrier bandwidth or is otherwise configured to use a limited carrier bandwidth (e.g., to conserve power).

[0083] In some cases, the eCC may utilize a symbol duration different from other component carriers, which may include using a reduced symbol duration compared to the symbol duration of other component carriers. The shorter symbol duration may be associated with an increased spacing between adjacent subcarriers. A device utilizing the eCC (such as UE 115 or base station 105) may transmit a broadband signal (e.g., according to a frequency channel or carrier bandwidth such as 20 MHz, 40 MHz, 60 MHz, 80 MHz) with a reduced symbol duration (e.g., 16.67 microseconds). The TTI in the eCC may consist of one or more symbol periods. In some cases, the TTI duration (i.e., the number of symbol periods in the TTI) may be variable.

[0084] The wireless communication system 100 may be a NR system, which may utilize any combination of licensed spectrum bands, shared spectrum bands, and unlicensed spectrum bands, etc. The flexibility of the eCC symbol duration and subcarrier spacing may allow the use of the eCC across multiple spectrums. In some examples, NR shared spectrum may improve spectrum utilization and spectrum efficiency, specifically through dynamic vertical resource sharing (e.g., in the frequency domain) and horizontal (e.g., in the time domain) resource sharing.

[0085] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, etc. These systems can be multi-access systems capable of supporting communication for multiple users by sharing available system resources (e.g., time, frequency, and power). A wireless network (e.g., a wireless local area network (WLAN), such as a Wi-Fi (i.e., Institute of Electrical and Electronics Engineers (IEEE) 802.11) network) can include access points (APs) that can communicate with one or more wireless or mobile devices. The AP can be coupled to a network such as the Internet and can enable mobile devices to communicate via the network (or communicate with other devices coupled to the access point). Wireless devices can communicate bidirectionally with network devices. For example, in a WLAN, a device can communicate with an associated AP via a downlink (e.g., a communication link from the AP to the device) and an uplink (e.g., a communication link from the device to the AP). A wireless personal area network (PAN) that can include a Bluetooth connection can provide a short-range wireless connection between two or more paired wireless devices. For example, a wireless device such as a cellular phone can utilize wireless PAN communication to exchange information such as audio signals with a wireless headset.

[0086] In some cases, URLLC and eMBB grants can be used for a differentiation framework. For example, URLLC and eMBB can be on two virtual component carriers (CCs) located at the same frequency. In this case, to support two services on the same carrier, the envelope performance may be sacrificed. In this case, a larger number of control channel elements (CCEs) and bandwidth parts (BDs) can be used. Generally, in this case, eMBB grants and URLLC grants can be differentiated because eMBB grants and URLLC grants may be in different control resource sets (CORESETs), where some CORESETs are configured to monitor eMBB downlink control information (DCI), and other CORESETs may be configured to monitor URLLC DCI. For example, up to 3 CORESETs can be monitored for eMBB DCI, and X CORESETs can be monitored for URLLC DCI, where X may be equal to 1 for below 6 GHz (i.e., FR1). Alternatively, eMBB grants and URLLC grants can be differentiated because they may have different DCI sizes. For example, for eMBB with a cell radio network temporary identifier (C-RNTI), the size can be 3, for URLLC with a C-RNTI, the size can be 1, and for other radio network temporary identifiers (RNTIs), the size can be 1.

[0087] In other cases, URLLC and eMBB grants can be used in a non-differentiated framework. For example, in some examples, URLLC and eMBB grants may not be explicitly separated. In this case, the same DCI format and size without additional priority information can be used. Additionally, the DCI size budget, the number of CORESETs, and the number of BDs may not increase. Alternatively, in other examples, eMBB and URLLC may not be distinguishable before DCI decoding. For example, once the UE 115 checks the RNTI associated with the DCI or the priority indication field in the DCI, the UE 115 can determine whether the grant is for a high-priority channel (e.g., URLLC PUSCH or URLLC PDSCH) or for a low-priority channel (e.g., eMBB PUSCH or eMBB PDSCH). Generally, the examples described throughout this disclosure can apply to cases where grants are distinguishable after decoding.

[0088] If the UE 115 cannot distinguish whether the DCI corresponds to an eMBB grant or a URLLC grant before decoding the DCI, the processing timeline may be affected, such as with respect to Figure 3 as shown. This problem may become more apparent when eMBB and URLLC follow different minimum processing capability timelines. Additionally or alternatively, this problem may become more apparent as the number of BDs per time slot increases.

[0089] In some cases, the UE 115 can be configured to operate with carrier aggregation. If the UE 115 indicates support for search space sharing via searchSpaceSharingCA-UL or searchSpaceSharing-DL, and if the UE 115 has a physical downlink control channel (PDCCH) candidate with a CCE aggregation level L in CORESET p. of DCI format 0_1 or DCI format 1_1 (which has a first size and is associated with serving cell n CI,2 ), then the UE 115 can receive the corresponding PDCCH via a PDCCH candidate with a CCE aggregation level L in CORESET p. of DCI format 0_1 or DCI format 1_1 (which has a second size and is associated with serving cell n CI,1 ), if the first size is the same as the second size. This situation can be referred to as search space sharing.

[0090] If URLLC grants and eMBB grants are used in a differentiated framework as described herein, then the base station 105 communicating with the UE 115 may send different DCI sizes to schedule eMBB and URLLC, or may send grants on different CORSETs, which can avoid search space sharing. However, if URLLC grants and eMBB grants are used in an undifferentiated framework, also as described herein, the base station 105 may use other methods (such as those described herein with respect to Figure 4A and Figure 4B ), to avoid problems that may be caused by search space sharing, such as those referenced Figure 3 as described.

[0091] In some cases, the UE 115 may send an indication regarding one or more channels that the UE 115 is capable of supporting at a first priority and one or more channels at a second priority, where the first priority is higher than the second priority. The UE 115 may receive signaling indicating a set of search spaces within a CORESET that corresponds to grant candidates for scheduling one or more channels at the first priority. The UE 115 may determine a second set of search spaces within the CORESET that corresponds to grant candidates for scheduling one or more channels at the second priority. The UE 115 may decode grants for scheduling one or more channels at the first priority within the search space of the first set of search spaces.

[0092] Figure 2 FIG. shows an example of a wireless communication system 200 that supports priority-based search space classification in accordance with aspects of the present disclosure. In some examples, the wireless communication system 200 may implement aspects of the wireless communication system 100. For example, the wireless communication system 200 may include a UE 115-a (which may be an example of the UE 115 referenced Figure 1 ), and a base station 105-a (which may be an example of the base station 105 referenced Figure 1 ). The URLLC grants and eMBB grants are described in Figure 2 , Figure 3 , Figure 4A and Figure 4B to illustrate an example of the methods of the present disclosure as described herein. Generally, the eMBB grant 220 may be considered a grant for low-priority channels (e.g., a grant for eMBB PDSCH or eMBB PDSCH), and the URLLC grant 225 may be considered a grant for high-priority channels (e.g., a grant for URLLC PDSCH or URLLC PDSCH).

[0093] The base station 105-a may send a downlink control transmission to the UE 115a via the PDCCH 205. In some cases, the base station 105-a may send the downlink control transmission on a CORESET 210 including a CCE 215. In some cases, a first subset of the CCEs 215 may include an eMBB grant 220 and a second subset of the CCEs may include a URLLC grant 225. The eMBB grant 220 and the URLLC grant 225 may be examples of DCI.

[0094] After decoding the eMBB grant 220, the UE 115-a may use the eMBB grant 220 to process the corresponding PDSCH or transmit the PUSCH. Similarly, when decoding the URLLC grant 225, the UE 115 may use the URLLC grant 225 to process the corresponding PDSCH or transmit the PUSCH. In some cases, if processing the PDSCH, the UE 115 may send feedback (e.g., HARQ acknowledgement (HARQ-ACK) feedback) to the base station 105-a via a physical uplink control channel (PUCCH) resource.

[0095] Figure 3 An example of a BD order 300 supporting priority-based search space classification according to aspects of the present disclosure is shown. In some examples, the BD order 300 can implement aspects of the wireless communication system 100. For example, the BD order 300 can be an order in which BDs 305 are executed by the UE 115. For example, BD 305-a (i.e., BD #1) can be executed first, and BD 305-c (i.e., BD #72) can be executed last. The BD order 300 can represent BDs performed on a single time slot and can vary according to the subcarrier spacing (e.g., 30kHz). Although Figure 3 , Figure 4A and Figure 4B Examples involving PDSCH are shown, but it should be understood that similar examples using PUSCH instead of PDSCH may be performed without departing from the scope of the present disclosure.

[0096] Each BD 305 can correspond to a search space 310 on a licensing candidate. For example, BD 305-b can have an associated search space 310-a, and BD 305-c can have an associated search space 310-b. Each search space 310 can span multiple CCEs 215. For example, in this example, search space 310-a can span CCEs 215-a, 215-b, 215-c, and 215-d, and search space 310-b can span CCEs 215-e, 215-f, 215-g, and 215-h. Since the eMBB license 220 and the URLLC license 225 are the same size and within the same CORESET, search space sharing can be allowed.

[0097] In this example, the eMBB license 220-a can be decoded at BD 305-b (i.e., BD#71), and the URLLC license 225-a can be decoded at BD 305-c (i.e., BD#72). If the UE 115 has already decoded the eMBB license 220-a at BD 305-b and has not decoded the URLLC license 225-a at BD 305-c, then the UE 115 may have enough time to decode the corresponding PDSCH transmission associated with the eMBB license 220-a before the resources for sending PUCCH feedback are exhausted. Alternatively, if the UE 115 has already decoded the URLLC license 225-a at BD 305-c and has not decoded the eMBB license 220-a at BD 305-b, then the UE 115 may have enough time to decode the corresponding PDSCH transmission associated with the URLLC license 225-a before the resources for sending PUCCH feedback are exhausted. However, as in this example, if the UE 115 decodes the eMBB license 220-a at BD 305-b and also decodes the URLLC license 225-a at BD 305-c, then the UE 115 may not have enough time to decode both corresponding PDSCH transmissions before the resources for sending PUCCH feedback are exhausted.

[0098] The lack of sufficient time may be caused, at least in part, by the lack of capacity of UE 115. For example, in order to process the PDSCH associated with the eMBB grant 220-a and the URLLC grant 225-a before the resources for sending PUCCH feedback are exhausted, UE 115 may use a processing capacity of 2X, where X may be the processing capacity for processing the PDSCH on one CC. However, UE 115 may have a maximum processing capacity of αX, where αX may be the processing capacity that UE 115 can use to process the PDSCH associated with the eMBB grant 220 received on one CC and simultaneously the PDSCH associated with the URLLC grant 225 received on another CC. Generally, since the blocks for data processing can be shared between two CCs, αX < 2X. Thus, UE 115 may not have enough time to process two PDSCHs on a single CC before the resources for sending PUCCH feedback are exhausted. Reference may be made to Figure 4A and Figure 4B describe methods for compensating for insufficient capabilities.

[0099] Figure 4A and Figure 4B illustrates examples of priority-based BD procedures 400-a and 400-b that support priority-based search space classification according to aspects of the present disclosure. In some examples, the priority-based BD procedures 400-a and 400-b may implement aspects of the wireless communication system 100. For example, the priority-based BD procedures 400-a and 400-b may be implemented by UE 115 when determining the order for decoding the search space.

[0100] To enable UE 115 with limited capabilities, such as in Figure 3As described in [description], to process PDSCH from eMBB grant 220 and URLLC grant 225 before the resources for PUCCH feedback are exhausted, UE 115 and serving base station 105 can use explicit rules. For example, UE 115 can receive an indication from serving base station 105 that indicates a first subset of the set of search spaces on which UE 115 can decode URLLC grant 225 or eMBB grant 220. Alternatively, the UE can decode URLLC grant 225 rather than eMBB grant 220 on the first subset. In either case, based on the first search space subset, UE 115 can determine a second subset of the set of search spaces on which UE 115 can decode eMBB grant 220 but not URLLC grant 225. For example, the second subset can be any search space in the set of search spaces that is not within the first subset. UE 115 can map the first subset to BD set 405-a and can map the second subset to BD set 405-b. Thus, UE 115 can perform BD 305 on the search space of the first subset before performing BD 305 on the search space of the second subset. In some cases, UE 115 can use a predetermined subset of the set of search spaces as the first search space set.

[0101] Generally, when eMBB grant 220 and URLLC grant 225 cannot be distinguished before decoding (such as regarding Figure 1 described), the methods described herein can be used. To mitigate search space sharing, UE 115 can identify or determine which search spaces to prioritize. UE 115 or serving base station 105 can define explicit rules. For example, if UE 115 supports two services or channels with different priorities, the DCI for the high-priority service can be within a predetermined set of search spaces or within a given number of search spaces. UE 115 may not expect to decode the DCI that schedules high-priority PDSCH or PUSCH in another search space.

[0102] Figure 4AScenarios where the UE 115 decodes the URLLC grant 225-b in the first subset and decodes the eMBB grant 220-b in the second subset can be represented. After decoding the URLLC grant 225-b at BD 305-d (i.e., BD#1), the UE 115 can start processing the corresponding PDSCH with processing capability X. At the same time, the UE 115 can continue to execute BD 305 until the end of BD set 405-a and can start executing BD 305 at the start of BD set 405-b. Once the UE 115 decodes the eMBB grant 220-b at BD 305-e (i.e., BD#18), the UE 115 can start processing the corresponding PDSCH. If the UE 115 has completed processing the PDSCH associated with the URLLC grant 225-b, the UE 115 can process the PDSCH associated with the eMBB grant 220-b with processing capability X. If the UE 115 has not completed processing the PDSCH associated with the URLLC grant 225-b, the UE 115 can start processing the PDSCH associated with the URLLC grant 225-b and the PDSCH associated with the eMBB grant 220-b simultaneously and may do so with a capability of βX or lower. However, since the UE 115 starts processing the PDSCH associated with the URLLC grant 225-b before processing the PDSCH associated with the eMBB grant 220-b, the UE 115 can have time to process both before the resources for PUCCH feedback are exhausted.

[0103] Figure 4BScenarios where the UE 115 decodes the URLLC grant 225-c and the eMBB grant 220-c in the first subset can be represented. After decoding the URLLC grant 225-c at BD 305-d (i.e., BD#1), the UE 115 can start processing the corresponding PDSCH with processing capability X. After decoding the eMBB grant at BD 305-f (i.e., BD#2) and assuming the UE 115 has not completed processing the PDSCH associated with the URLLC grant 225-c, the UE 115 can start processing two PDSCHs simultaneously with a capability of βX or lower. Alternatively, the UE 115 can first complete processing the URLLC PDSCH with processing capability X and then can process the eMBB PDSCH. In either case, since both the URLLC grant 225-c and the eMBB grant 220-c have been decoded before BD 305 of BD set 405-b, the UE 115 can have enough time to process the PDSCHs associated with both before the resources for sending PUCCH feedback are exhausted. In other cases, the UE 115 can decode the eMBB grant 220-c before decoding the URLLC grant 225-c (e.g., the eMBB grant 220-c can be decoded at BD 305-d and the URLLC grant 225-c can be decoded at BD 305-f).

[0104] Figure 5 An example of a process flow 500 that supports priority-based search space classification in accordance with aspects of the present disclosure is shown. In some examples, the process flow 500 can implement aspects of the wireless communication system 100. For example, the process flow 500 can include a UE 115-b (which can be an example of the UE 115 as described in reference Figure 1 described) and a base station 105-b (which can be an example of the base station 105 as described in reference Figure 1 described).

[0105] At 505, the UE 115-b can send information regarding one or more channels that the UE 115-b is capable of supporting at a first priority (e.g., URLLC PDSCH or URLLC PUSCH) and one or more channels at a second priority (e.g., eMBB PDSCH or eMBB PUSCH). The first priority can be higher than the second priority. The base station 105-b can receive the indication.

[0106] At 510, base station 105-b may identify a first search space set in a CORESET and a second search space in the CORESET, where the first search space set corresponds to candidates for grants for scheduling one or more channels of a first priority, and the second search space corresponds to candidates for grants for scheduling one or more channels of a second priority.

[0107] At 515, base station 105-b may send signaling indicating the first search space set in the CORESET, which corresponds to candidates for grants for scheduling one or more channels of a first priority. In some cases, base station 105-b may send signaling indicating a third search space set, and the first search space set is a subset of the third search space set. Additionally or alternatively, base station 105-b may send signaling indicating the format (e.g., DCI format) of the candidates for grants associated with the first search space set. UE 115-b may receive the signaling.

[0108] At 520, UE 115-b may determine a second search space set in the CORESET, which corresponds to candidates for grants for scheduling one or more channels of a second priority. In some cases, UE 115-b may determine that the second search space set includes each search space in the third search space set that is not the first search space set.

[0109] At 525, base station 105-b may send a first grant for scheduling one or more channels of a first priority on a CCE in the search space corresponding to the first search space set. Additionally or alternatively, base station 105-b may send a grant for scheduling one or more channels of a second priority on a second CCE in the second search space corresponding to the first search space set. Additionally or alternatively, base station 105-b may send a grant for scheduling one or more channels of a second priority on a CCE in the first search space corresponding to the first search space set. The grant may be DCI. In some cases, base station 105-b may avoid sending a grant for scheduling one or more channels of a first priority on one or more CCEs in the search space corresponding to the second search space set.

[0110] At 530, UE 115-b may decode a grant for scheduling one or more channels of a first priority within a search space of a first search space set. UE 115-b may determine that the grant is for scheduling one or more channels of the first priority based on an RNTI, a priority indication bit field, or a combination thereof. Additionally or alternatively, UE 115-b may decode a grant for scheduling one or more channels of a second priority within a second search space of the first search space set. In some cases, UE 115-b may fail to decode a grant for scheduling one or more channels of the first priority in each search space of the second search space set based on the second search space set being associated with one or more channels of the second priority.

[0111] Figure 6 FIG. 600 is a block diagram of a device 605 supporting priority-based search space classification in accordance with aspects of the present disclosure. Device 605 may be an example of an aspect of UE 115 as described herein. Device 605 may include a receiver 610, a communication manager 615, and a transmitter 620. Device 605 may also include a processor. Each of these components may communicate with one another (e.g., via one or more buses).

[0112] Receiver 10 may receive information associated with various information channels (e.g., control channels, data channels, and information related to priority-based search space classification, etc.), such as packets, user data, or control information. The information may be passed to other components of device 605. Receiver 610 may be an example of an aspect of transceiver 915 as described Figure 9 herein. Receiver 610 may utilize a single antenna or an antenna set.

[0113] Communication manager 615 may receive signaling indicating a first search space set within a CORESET that corresponds to grant candidates for scheduling one or more channels of a first priority. Communication manager 615 may determine a second search space set within the CORESET that corresponds to grant candidates for scheduling one or more channels of a second priority, where the first priority is higher than the second priority. Communication manager 615 may decode a grant for scheduling one or more channels of the first priority within a search space of the first search space set. Communication manager 615 may be an example of an aspect of communication manager 910 as described herein.

[0114] The communication manager 615 or its sub-components may be implemented in hardware, processor-executed code (e.g., software or firmware), or any combination thereof. If implemented in processor-executed code, the functions of the communication manager 615 or its sub-components may be performed by a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designated to perform the functions described in this disclosure.

[0115] The communication manager 615 or its sub-components may be physically located in various positions, including being distributed such that portions of the functions are implemented by one or more physical components at different physical locations. In some examples, in accordance with various aspects of the present disclosure, the communication manager 615 or its sub-components may be separate and distinct components. In some examples, the communication manager 615 or its sub-components may be combined with one or more other hardware components, including but not limited to input / output (I / O) components, transceivers, network servers, another computing device, one or more other components described in this disclosure, or combinations thereof in accordance with various aspects of the present disclosure.

[0116] The transmitter 620 may transmit signals generated by other components of the device 605. In some examples, the transmitter 620 may be co-located with the receiver 610 in a transceiver module. For example, the transmitter 620 may be an example of aspects of the transceiver 915 described in Figure 9 reference. The transmitter 620 may utilize a single antenna or an antenna set.

[0117] In some examples, the communication manager 515 may be implemented as an integrated circuit or chipset for a mobile device modem, and the receiver 510 and transmitter 520 may be implemented as analog components (e.g., amplifiers, filters, antennas) coupled to the mobile device modem to enable wireless transmission and reception via one or more frequency bands.

[0118] The communication manager 615 as described herein may be implemented to achieve one or more potential advantages. One implementation may allow the device 605 to provide assistance for enabling a carrier aggregation framework to support simultaneous URLLC and eMBB communications. Based on techniques for enabling a carrier aggregation framework to support simultaneous URLLC and eMBB communications between the device 605 and a base station, the device 605 may support reduced search space sharing and, thus, support reduced processing capacity limitations.

[0119] Thus, device 605 can increase the likelihood of accurately decoding DCI for URLLC and eMBB communications, and can thus communicate via a channel with a greater likelihood of successful communication. In some examples, based on the greater likelihood of successful communication, device 605 can more efficiently power a processor or one or more processing units associated with the carrier aggregation framework to support simultaneous URLLC and eMBB communications, which can enable the device to save power and increase battery life.

In some examples, the grant decoding component 820 may decode each search space of the second search space set. In some cases, the grant decoding component 820 may fail to decode a grant for scheduling one or more channels of a first priority in each search space of the second search space set based on the second search space set being associated with one or more channels of a second priority. In some examples, the grant decoding component 820 may fail to decode a grant for scheduling one or more channels of a second priority in each search space of the first search space set based on the first search space set being associated with one or more channels of a first priority.

[0131] The capability information transmitter 825 may send an indication to the base station and before receiving signaling that the UE is capable of supporting one or more channels of a first priority and one or more channels of a second priority, where the signaling is received from the base station.

The techniques described herein can be used for synchronous operation or asynchronous operation.

[0202] The information and signals described herein can be represented using any of a variety of different processes and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the specification can be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.

[0203] The various illustrative blocks and modules described in connection with the disclosure herein can be implemented or executed with a general-purpose processor, DSP, ASIC, FPGA, or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general-purpose processor can be a microprocessor, but in the alternative, the processor can be any processor, controller, microcontroller, or state machine. The processor can also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration).

[0204] The functions described herein can be implemented in hardware, software executed by a processor, firmware, or any combination thereof. If implemented in software executed by a processor, the functions can be stored on or transmitted via a computer-readable medium as one or more instructions or code. Other examples and implementations are within the scope of the present disclosure and the appended claims. For example, due to the nature of software, the functions described herein can be implemented with a processor, hardware, firmware, hardwiring, or any combination thereof. The features implementing the functions can also be physically located in different positions, including being distributed, such that parts of the functions are implemented at different physical locations.

[0205] A computer-readable medium includes a non-transitory computer storage medium and a communication medium, where the communication medium includes any medium that facilitates transfer of a computer program from one place to another. The non-transitory storage medium can be any available medium that can be accessed by a general-purpose or special-purpose computer. By way of example and not limitation, the non-transitory computer-readable medium can include RAM, ROM, electrically erasable programmable ROM (EEPROM), flash memory, compact disc (CD) ROM or other optical disc storage, magnetic disk storage or other magnetic storage devices, or any other non-transitory medium that can be used to carry or store the desired program code components in the form of instructions or data structures and that can be accessed by a general-purpose or special-purpose computer or a general-purpose or special-purpose processor. Additionally, any connection is properly termed a computer-readable medium. For example, if software is transferred from a website, server, or other remote source using coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of the medium. As used herein, disk and disc include CD, laser disc, optical disc, digital versatile disc (DVD), floppy disk, and Blu-ray disc, where disks typically reproduce data magnetically, while discs reproduce data optically with lasers. Combinations of the above are also included within the scope of computer-readable medium.

[0206] As used herein, and as included in the claims, the "or" used in a list of items (e.g., a list that begins with a phrase such as "at least one of... " or "one or more of... ") indicates an inclusive list, such that a list of at least one of A, B, or C, for example, means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Additionally, as used herein, the phrase "based on" should not be construed as a reference to a closed set of conditions. For example, an exemplary step described as "based on condition A" can be based on both condition A and condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase "based on" should be interpreted in the same manner as the phrase "at least partially based on".

[0207] In the drawings, like components or features may have the same reference numeral. Additionally, various components of the same type can be distinguished by following the reference numeral with a dash and a second label that differentiates the similar components. If only the first label is used in the specification, the description applies to any one of the similar components having the same first reference numeral, regardless of the second label or other subsequent reference numerals.

[0208] The description set forth herein with reference to the accompanying drawings describes example configurations and does not represent all examples that can be implemented or that are within the scope of the claims. The term “exemplary” as used herein means “serving as an example, instance, or illustration” and not “preferred” or “superior to other examples.” To provide an understanding of the described techniques, the detailed description includes specific details. However, the techniques may be practiced without these specific details.
