Abstract

Methods, systems, and devices for wireless communications are described to support complexity reduction for control resource sets (CORESETs). A low-complexity user equipment (UE) may experience performance degradation if the number of resource block (RB) groups in a CORESET is above a given threshold, or if any symbols of the CORESET are multiplexed with any other signal or channel. A base station may configure a CORESET for a low-complexity UE to support reduced-complexity information detection compared to CORESETs configured for other UEs. The configured CORESET may be based on one or more capabilities of the low-complexity UE and may include a reduced number of RB groups or may avoid overlap with any other signal or channel. If a CORESET configured for a low-complexity UE does not support complexity reduction, the UE may refrain from decoding search space candidates on the CORESET.

Technical Field

[0003] The following relates generally to wireless communications and, more particularly, to controlling resource configuration. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, and the like. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, advanced LTE (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 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 node simultaneously supporting communication with multiple communication devices, which may also be referred to as user equipment (UE).

[0005] In some cases, a UE may be limited in terms of processing capability, power availability, or memory, etc. Such a UE may experience reduced performance when decoding transmissions on some resource configurations. Summary of the Invention

[0006] The described techniques relate to improved methods, systems, devices, and apparatuses for supporting control resource configuration. Generally speaking, the described techniques provide for reducing the complexity of detecting control information on one or more control resource sets (CORESETs). In some cases, if the number of resource block (RB) groups in a CORESET is above a given threshold, a low-complexity user equipment (UE) may experience reduced performance even if the number of RB groups complies with network-imposed restrictions. In addition, some networks may not support restrictions on RB groups for CORESETs associated with control channels with narrowband reference signals, resulting in reduced performance for low-complexity UEs. If a CORESET is multiplexed with one or more other signals or channels, a low-complexity UE may experience similar disadvantages. Therefore, a base station may configure a CORESET for a low-complexity UE (e.g., or other types of UEs) such that the CORESET can support reduced complexity of UE operation compared to a CORESET configured for a different type of UE. Such a CORESET may be referred to as a reduced-complexity CORESET. In some cases, if the CORESET configured for a low-complexity UE (eg, or other UE) is not a reduced-complexity CORESET, the UE may refrain from decoding downlink control messages or search space candidates on the CORESET.

[0007] The first UE and the second UE may indicate one or more corresponding capabilities to the base station, and the base station may configure a first CORESET of the first UE (e.g., a low complexity UE or other type of UE) and a second CORESET of the second UE (e.g., a different type of UE) based on the one or more corresponding capabilities. The one or more capabilities of the UE may include the number of supported RB groups or multiplexing capabilities. In some cases, the first CORESET may represent a reduced complexity CORESET, where the number of RB groups of the first CORESET may be limited, or where the first CORESET may be restricted from multiplexing operation with one or more other signals or channels. The first UE may identify the first CORESET, identify characteristics of the first CORESET, and determine whether to decode search space candidates or control messages on the first CORESET based on the identified characteristics and the one or more capabilities of the first UE. The characteristics of the first CORESET may represent the number of RB groups of the CORESET or the number of symbols that the CORESET overlaps with one or more other signals or channels.

[0008] If the first UE determines that the characteristics of the first CORESET correspond to the corresponding capabilities of the first UE, the first UE may decode the search space candidates or control messages on the CORESET. For example, the number of RBs of the CORESET may correspond to the number of RBs decodable by the first UE, or the number of symbols overlapped with one or more other signals or channels may correspond to the number of overlapping symbols decodable by the first UE. If the first UE determines that the characteristics of the first CORESET (e.g., the number of RBs, the number of overlapping symbols) do not correspond to the capabilities of the first UE (e.g., decodable RBs, decodable overlapping symbols), the first UE may refrain from decoding the search space candidates or control messages.

The method may include: sending an indication of a supported number of RB groups for a control channel to a base station; identifying a CORESET associated with the control channel, the CORESET including one or more RB groups; identifying a number of the one or more RB groups based on identifying the CORESET; and determining whether to decode a control message on the CORESET based on the supported number of RB groups and the number of the one or more RB groups.

[0081] The base station may send one or more control messages to a user equipment (UE) via the frequency and time resources configured in a control resource set (CORESET) associated with a control channel. The CORESET may provide resource blocks (RBs) and symbol durations for the monitoring opportunities of the control channel, and the search space associated with the CORESET may provide the periodicity and offset of the monitoring opportunities of the control channel. In some cases, a CORESET may include multiple groups of consecutive RBs (e.g., clusters).

[0082] In some cases, the UE may represent a low-complexity UE or other type of UE. As described herein, a low-complexity UE may represent a UE that operates with a lower level of processing capability, a UE that has fewer features or capabilities than other UEs, or a UE that is in a low-power or low-complexity operating mode. A low-complexity UE (e.g., or other UE) may benefit from simplification of the CORESET, for example, by limiting the number of groups of contiguous RBs in a configured CORESET. In some wireless communication systems, the network may limit the number of groups of RBs in a CORESET for a control channel with a wideband reference signal. For example, the network may limit the number of groups of RBs in a CORESET to four contiguous RB groups.

[0083] In some cases, if the number of RB groups in a CORESET is above a given threshold (e.g., while still complying with configured restrictions), a low-complexity UE (e.g., or other types of UEs) may experience delays, increased power consumption, overall performance degradation, etc. In addition, some systems may not support restrictions on RB groups for CORESETs associated with control channels with narrowband reference signals. As such, a low-complexity UE (e.g., or other types of UEs) configured with a CORESET associated with a narrowband reference signal may experience delays, increased power consumption, overall performance degradation, etc. A low-complexity UE (e.g., or other types of UEs) may experience similar disadvantages if the CORESET is multiplexed with one or more other signals or channels.

[0084] Thus, a base station may configure a CORESET for a low-complexity UE such that the CORESET may support reduced complexity of UE operation (e.g., for detecting information on the CORESET) compared to a CORESET configured for a different type of UE. Such a CORESET may be referred to as a reduced-complexity CORESET, where the CORESET may support reduced complexity of information detection at the UE and may include simplified resource characteristics for reduced complexity. In some cases, if the CORESET of a low-complexity UE is not a reduced-complexity CORESET, the low-complexity UE may refrain from decoding downlink control messages or search space candidates on the CORESET.

[0085] For example, a base station may configure a first CORESET for a first UE (e.g., a low complexity UE or other type of UE) and may configure a second CORESET for a second UE (e.g., a different type of UE). The base station may indicate the corresponding CORESET configuration to the UE. In some cases, the first CORESET may represent a CORESET with reduced complexity, where the number of RB groups of the first CORESET may be limited, or where the first CORESET may be restricted from multiplexing operation with one or more other signals or channels. The configuration of the first CORESET may be based on one or more capabilities of the first UE. The first UE may receive one or more control channels or control messages through the first CORESET based on the configuration of the CORESET. Based on the configuration of the first CORESET, the UE may experience reduced latency, reduced power consumption, and overall performance enhancement. Based on one or more capabilities of the second UE, the second CORESET may represent a CORESET without reduced complexity.

[0086] In some cases, the base station may configure the first CORESET without complexity reduction (e.g., without simplification) or without one or more aspects of complexity reduction, such that the first CORESET may not represent a reduced-complexity CORESET. For example, the first CORESET may include a greater number of RB groups than supported by the first UE. Additionally or alternatively, the first CORESET may be multiplexed with one or more other signals or channels. The first UE may determine that the first CORESET includes a greater number of RB groups than supported by the UE, or that the first CORESET is multiplexed with one or more other signals or channels. Based on determining that the first CORESET is configured without one or more aspects of complexity reduction, the first UE may determine to refrain from decoding downlink control messages or control channels on the first CORESET.

[0087] Aspects of the present disclosure are initially described in the context of wireless communication systems. Aspects of the present disclosure are further described by and with reference to resource configurations, process flows, apparatus diagrams, system diagrams, and flowchart illustrations related to controlling resource configuration.

[0088] Figure 1An example of a wireless communication system 100 supporting control resource configuration according to aspects of the present disclosure is shown. 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.

[0089] Base stations 105 may be dispersed throughout a geographic area to form wireless communication system 100 and may be devices of different forms or capabilities. Base stations 105 and UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which UEs 115 and base stations 105 may establish one or more communication links 125. Coverage areas 110 may be examples of geographic areas over which base stations 105 and UEs 115 may support communication of signals according to one or more radio access technologies.

[0090] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary, mobile, or both at different times. The UEs 115 may be devices of different forms or capabilities. Figure 1 Some example UEs 115 are shown in FIG. The UEs 115 described herein are capable of communicating with various types of devices, such as other UEs 115, base stations 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices). Figure 1 shown.

[0091] The base stations 105 can communicate with the core network 130, or with each other, or with both. For example, the base stations 105 can interface with the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). The base stations 105 can communicate with each other via the backhaul links 120 (e.g., via X2, Xn, or other interfaces) directly (e.g., directly between the base stations 105) or indirectly (e.g., via the core network 130), or both. In some examples, the backhaul links 120 can be or include one or more wireless links.

[0092] One or more of the base stations 105 described herein may include or may be referred to by one of ordinary skill in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB), a next generation NodeB or a giga NodeB (any of which may be referred to as a gNB), a Home NodeB, a Home eNodeB, or other suitable technical terminology.

[0093] UE 115 may include or be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable technical terminology, where "device" may also be referred to as a unit, a station, a terminal, or a client, etc. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc., which may be implemented in various objects, such as appliances, vehicles, meters, etc.

[0094] The UE 115 described herein can communicate with various types of equipment, such as other UEs 115 and base stations 105, which can sometimes act as relays, and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 shown.

[0095] The UE 115 and the base station 105 can wirelessly communicate with each other via one or more communication links 125 over one or more carriers. The term "carrier" may refer to a collection of radio spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, a carrier used for the communication link 125 may include a portion of a radio spectrum band (e.g., a bandwidth part (BWP)) operating according to one or more physical layer channels of a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operation, user data, or other signaling. The wireless communication system 100 may use carrier aggregation or multi-carrier operation to support communication with the UE 115. Depending on the carrier aggregation configuration, the UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used with frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers.

[0096] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling to coordinate the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be located according to a channel raster for discovery by a UE 115. A carrier may be operated in a standalone mode, where initial acquisition and connection may be performed by a UE 115 via the carrier, or in a non-standalone mode, where a connection is anchored using a different carrier (e.g., of the same or different radio access technology).

[0097] 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. A carrier may carry downlink communications or uplink communications (e.g., in FDD mode), or may be configured to carry both downlink and uplink communications (e.g., in TDD mode).

[0098] A carrier can be associated with a particular bandwidth of a radio spectrum, and in some examples, the carrier bandwidth can be referred to as the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth can be one of a plurality of determined bandwidths of a carrier for a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). The devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) can have a hardware configuration that supports communication over a particular carrier bandwidth, or can be configured to support communication over one of a set of carrier bandwidths. In some examples, the wireless communication system 100 can include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 can be configured to operate over a portion (e.g., subband, BWP) or all of the carrier bandwidth.

[0099] The signal waveform transmitted via the carrier may be composed of multiple subcarriers (e.g., using a multicarrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may include one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing are inversely correlated. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements a UE 115 receives and the higher the order of the modulation scheme, the higher the data rate for the UE 115 may be. Wireless communication resources may refer to a combination of radio spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may further improve the data rate or data integrity of communications with the UE 115.

[0100] One or more parameter sets for a carrier may be supported, where the parameter set may include subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs with the same or different parameter sets. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time, and communication by the UE 115 may be restricted to the one or more active BWPs.

[0101] The time interval of the base station 105 or the UE 115 can be expressed as a multiple of a basic time unit, where the basic time unit can be, for example, T s =1 / (Δf max ·N f ) seconds of sampling period, where Δf max It can represent the maximum supported subcarrier spacing, and N f The maximum supported Discrete Fourier Transform (DFT) size may be indicated. Time intervals of communication resources may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0102] Each frame may include a plurality of consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a plurality of 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 plurality of symbol periods (e.g., depending on the length of a cyclic prefix prepended to each symbol period). In some wireless communication systems 100, a time slot may be further divided into a plurality of micro-time slots containing one or more symbols. In addition to the cyclic prefix, each symbol period may contain one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the frequency band of operation.

[0103] A subframe, slot, mini-slot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI)).

[0104] 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, for example, using one or more of time division multiplexing (TDM), frequency division multiplexing (FDM), or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) for a physical control channel can be defined by multiple symbol periods and can extend across the system bandwidth of a carrier or a subset of the system bandwidth. One or more control regions (e.g., CORESETs) can be configured for a set of UEs 115. For example, one or more of the UEs 115 can monitor or search the control region for control information according to one or more search space sets, and each search space set can include one or more control channel candidates of one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information of a control information format having a given payload size. Search space sets can include a common search space set configured for transmitting control information to multiple UEs 115, and a UE-specific search space set for transmitting control information to a specific UE 115.

[0105] In some examples, base stations 105 can be mobile, and thus provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies can overlap, but the different geographic coverage areas 110 can be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies can be supported by different base stations 105. The wireless communication system 100 can include, for example, a heterogeneous network in which different types of base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

[0106] Some UEs 115 may be configured to employ a mode of operation that reduces power consumption, such as half-duplex communication (e.g., a mode that supports unidirectional 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 for the UE 115 include entering a power-saving deep sleep mode when not engaged in active communication, operating over a limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of a carrier, or outside a carrier.

[0107] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, the 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 critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private communication or group communication and can be supported by one or more mission-critical services such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions can include prioritization of services, and mission-critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency can be used interchangeably in this article.

[0108] In some examples, UE 115 can also communicate directly with other UEs 115 via device-to-device (D2D) communication links 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communication can be within the geographic coverage area 110 of base station 105. Other UEs 115 in such a group can be outside the geographic coverage area 110 of base station 105 or unable to receive transmissions from base station 105. In some examples, a group of UEs 115 communicating via D2D communication can utilize a one-to-many (1:M) system, in which each UE 115 transmits to each 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 UEs 115 without involving base station 105.

[0109] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) that manages access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) that routes packets to or interconnects with an external network. The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for UEs 115 served by base stations 105 associated with the core network 130. User IP packets may be delivered through the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to the network operator IP service 150. Operator IP services 150 may include access to the Internet, Intranet(s), IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0110] Some of the network devices (such as base stations 105) may include subcomponents, such as access network entities 140, which may be examples of access node controllers (ANCs). Each access network entity 140 may communicate with the UE 115 through one or more other access network transport entities 145, which may be referred to as radio heads, smart radio heads, or transmit / receive points (TRPs). 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 heads and ANCs) or consolidated into a single network device (e.g., base station 105).

[0111] The wireless communication system 100 can operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally speaking, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately 1 decimeter to 1 meter in length. UHF waves may be blocked or redirected by buildings and environmental features, but the waves can penetrate enough structures for a macro cell to provide service to a UE 115 located indoors. Transmissions using UHF waves can be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to transmissions using smaller frequencies and longer wavelengths in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0112] The wireless communication system 100 can utilize licensed and unlicensed radio spectrum bands. For example, the wireless communication system 100 can employ license assisted access (LAA), LTE-unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in an unlicensed radio spectrum band, devices such as the base station 105 and the UE 115 can employ carrier sensing for conflict detection and avoidance. In some examples, operations in the unlicensed band can be based on a carrier aggregation configuration in conjunction with component carriers operating in a licensed band (e.g., LAA). Operations in the unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.

[0113] The base station 105 or 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) communications, or beamforming. The antennas of the base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, the antennas or antenna arrays associated with the base station 105 may be located at different geographical locations. The base station 105 may have an antenna array with multiple rows and columns of antenna ports that the base station 105 may use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming of signals transmitted via the antenna ports.

[0114] The base station 105 or UE 115 can use MIMO communication to exploit multipath signal propagation and improve spectral efficiency by sending or receiving multiple signals via different spatial layers. Such a technique may be referred to as spatial multiplexing. Multiple signals may be sent, for example, by a transmitting device via different antennas or different combinations of antennas. Similarly, multiple signals may be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO) in which multiple spatial layers are sent to the same receiving device and multi-user MIMO (MU-MIMO) in which multiple spatial layers are sent to multiple devices.

[0115] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that can be used at a transmitting device or a receiving device (e.g., a base station 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals communicated via antenna elements of an antenna array so that some signals propagating at a particular orientation relative to the antenna array experience constructive interference while other signals experience destructive interference. Adjustments to signals communicated via antenna elements can include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to the signals carried via the antenna elements associated with the device. The adjustments associated with each antenna element can be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0116] The wireless communication system 100 can be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or packet data convergence protocol (PDCP) layer can be IP-based. The radio link control (RLC) layer can perform packet segmentation and reassembly to communicate over logical channels. The media access control (MAC) layer can perform priority processing and multiplex logical channels into transport channels. The MAC layer can also use error detection technology, error correction technology, or both to support retransmission 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 the UE 115 and the base station 105 or the core network 130 that supports the radio bearer of the user plane data. At the physical layer, the transport channel can be mapped to the physical channel.

[0117] A control channel may be associated with a CORESET and a search space that provides an opportunity to monitor the control channel. Multiple types of control channel demodulation reference signals (DMRS) may be defined for a CORESET. The two types of DMRS may include wideband reference signals (e.g., wideband DMRS) and narrowband reference signals (e.g., narrowband DMRS). When at least one resource element group bundle of a control channel is transmitted in a segment of all consecutive RBs allocated to a CORESET, the wideband DMRS may be transmitted over the segment. The same precoder may be used in the segmentation of the RB, which may be configured via RRC signaling. Narrowband DMRS may be transmitted in the resource element group bundle that constitutes the control channel and may not be transmitted in other resources of the segment that does not carry the resource element group associated with the control message. The same precoder may be used in each bundle of the resource element group of the control channel, which may be configured via RRC signaling.

[0118] A CORESET may include multiple contiguous RB groups, where the RB groups may support FDM of the CORESET and other signals, such as synchronization signal blocks (SSBs) and cell-specific reference signals (CRSs). In some cases, the number of RB groups in a CORESET may have less impact on narrowband DMRS than on wideband DMRS.

[0119] In some cases, if the number of RB groups in a CORESET is above a given threshold, a low-complexity UE (e.g., or other types of UE) may experience reduced performance, even if the number of RB groups complies with network-imposed restrictions. Furthermore, some networks may not support restrictions on RB groups for a CORESET associated with a control channel with a narrowband reference signal, resulting in reduced performance for low-complexity UEs. Low-complexity UEs may experience similar disadvantages if the CORESET is multiplexed with one or more other signals or channels. Therefore, a base station may configure a CORESET for a low-complexity UE that supports reduced complexity of UE operation (e.g., detecting information) compared to a CORESET configured for a different type of UE. Such a CORESET may be referred to as a reduced-complexity CORESET. For example, a reduced-complexity CORESET may include a smaller number of RB groups or may not overlap with any other signals or channels. In some cases, if the CORESET for a low-complexity UE is not a reduced-complexity CORESET, the low-complexity UE may refrain from decoding downlink control messages or search space candidates on the CORESET.

[0120] Figure 2An example of a wireless communication system 200 that supports control resource configuration according to aspects of the present disclosure is shown. In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100. For example, the wireless communication system 200 can include a base station 105-a and UEs 115-a and 115-b, which can be reference Figure 1 1 and 115. Base station 105-a may communicate with UE 115-a and UE 115-b in the downlink or uplink. For example, base station 105-a may send one or more downlink control messages 205 to UE 115-a or UE 115-b. Base station 105-a may send one or more downlink control messages 205 via frequency and time resources configured in CORESET 210 associated with the corresponding control channel.

[0121] The CORESET 210 may provide RBs and symbol durations for monitoring opportunities for a control channel (e.g., a physical downlink control channel (PDCCH)). In some cases, the CORESET 210 may include multiple groups of consecutive RBs (e.g., a cluster). The base station 105-a may send one or more downlink control messages 205 associated with the control channel to the UE 115-a or UE 115-b via the corresponding CORESET 210. The control channel may include one or more DMRSs for the UE 115 to estimate and track the control channel. Based on the configuration of the control channel, the DMRS may include a wideband reference signal or a narrowband reference signal.

[0122] In some cases, a UE 115 (e.g., UE 115-a) may represent a low-complexity UE 115 or another type of UE 115. For example, UE 115-a may represent a low-complexity UE 115, while UE 115-b may represent another type of UE 115 (e.g., a full-capability or non-low-complexity UE 115). As described herein, a low-complexity UE 115 may represent a UE 115 that operates with a lower level of processing capabilities, a UE 115 that has fewer features or capabilities than other UEs 115 (e.g., an NR-lite UE 115 or a reduced-capability UE 115), or a UE 115 that is in a low-power or low-complexity operating mode. UE 115-a may benefit from simplification of the CORESET 210, for example, by limiting the number of groups of contiguous RBs in the configured CORESET 210 (e.g., to reduce decoding complexity at UE 115-a). In some wireless communication systems, the network may limit the number of groups of RBs in CORESET 210 for control channels with wideband reference signals. For example, the network may limit the number of groups of RBs in CORESET 210-a to four consecutive RB groups.

[0123] In some cases, if the number of RB groups in a CORESET 210 is above a given threshold (e.g., while still below a limit), and in some cases, if the number of RB groups is greater than one, the UE 115-a may experience delays, increased power consumption, or overall performance degradation, among other things. Furthermore, some systems may not support restrictions on RB groups for a CORESET 210 associated with a control channel having a narrowband reference signal. Thus, if a UE 115-a is configured with a CORESET 210 associated with a narrowband reference signal, the UE 115-a may experience delays, increased power consumption, or overall performance degradation, among other things. If the CORESET 210 is multiplexed (e.g., FDMed) with one or more other signals or channels, the UE 115-a may experience similar disadvantages.

[0124] Thus, the base station 105 may configure a CORESET 210 for a UE 115-a such that the CORESET can support reduced complexity of UE operation (e.g., detecting or decoding information) compared to a CORESET 210 configured for a different type of UE 115 (e.g., UE 115-b). Such a CORESET 210 may be referred to as a reduced-complexity CORESET 210, where the reduced-complexity CORESET 210 can support reduced complexity of information detection at the UE 115-a and can include simplified resource characteristics to reduce complexity. In some cases, if the CORESET 210 of the UE 115-a is not a reduced-complexity CORESET 210, the UE 115-a may refrain from decoding the downlink control message 205 on the CORESET 210.

[0125] In one example, a base station 105-a may configure a CORESET 210-a for a UE 115-a (e.g., a low-complexity or other type of UE 115) and may configure a CORESET 210-b for a UE 115-b (e.g., a different type of UE 115). The base station 105-a may indicate the respective CORESET configurations to the UEs 115-a and 115-b via respective configuration messages 215-a and 215-b (e.g., RRC messages). In some cases, the CORESET 210-a may represent a reduced-complexity CORESET 210, wherein the number of RB groups of the CORESET 210-a may be limited, or wherein the CORESET 210-a may be restricted to FDM operation with one or more other signals or channels. Based on the configuration of the CORESET 210-a, the UE 115-a may experience reduced latency, reduced power consumption, and improved overall communication quality. Based on one or more capabilities of the UE 115 - b , the CORESET 210 - b may represent a CORESET 210 with no reduction in complexity.

[0126] In some cases, the base station 105-a may configure the CORESET 210-a without reducing complexity (e.g., without simplification) or without reducing one or more aspects of complexity, such that the CORESET 210-a may not represent a reduced-complexity CORESET 210. For example, in some cases, the CORESET 210-a may be configured similarly to the CORESET 210-b or may include a greater number of RB groups than supported by the UE 115-a. Additionally or alternatively, the CORESET 210-a may be multiplexed (e.g., FDMed) with one or more other signals or channels. In this case, the UE 115-a may determine that the CORESET 210-a includes a greater number of RB groups than supported by the UE 115-a or that the CORESET 210-a is multiplexed with one or more other signals or channels. Based on determining that the CORESET 210 - a is configured without one or more aspects of complexity reduction, the UE 115 - a may determine to refrain from decoding the downlink control message 205 on the CORESET 210 - a .

[0127] Figure 3A and Figure 3B 1 and 2 illustrate respective examples of resource configurations 301 and 302 that support control resource configuration according to aspects of the present disclosure. In some examples, resource configurations 301 and 302 can implement or be implemented by aspects of wireless communication systems 100 or 200. For example, resource configurations 301 and 302 can each include a CORESET 310 configured by base station 105 for UE 115, where base station 105 and UE 115 can be reference Figure 1 and Figure 2 Examples of corresponding devices described. In some examples, UE 115 can be a low-complexity or other type of UE 115.

[0128] Resource configurations 301 and 302 may include an example of a reduced complexity CORESET 310 configured on a time slot 305, as described with reference to FIG. Figure 2As described. For example, the base station 105 may configure the CORESETs 310-a and 310-b to include a number of RB groups 320 (e.g., contiguous RB groups) that is less than or equal to the number of RB groups 320 supported by the UE 115 (e.g., a threshold number of RB groups 320). For example, the number of RB groups 320 included in the CORESETs 310-a and 310-b may be less than four RB groups 320 (e.g., to reduce the complexity of the UE 115), and in some cases may be one RB group 320. In some cases, the number of supported RB groups 320 may be based on the type of the UE 115 (e.g., where the type may include a low-complexity UE 115) or based on one or more capabilities of the UE 115 (e.g., reported by the UE 115 in a capabilities message). In some cases, the capability type of the UE 115 may be indicated by an index (e.g., which may be signaled to the base station 105 to indicate the capability type).

[0129] Resource configuration 301 may include an example of a reduced-complexity CORESET 310-a that includes one RB group 320-a, where the one RB group 320-a may be based on the number of RB groups 320 supported by UE 115. In some cases, resource configuration 302 may include an example of a reduced-complexity CORESET 310-b that includes multiple (e.g., two or three) RB groups 320 (e.g., RB group 320-b and any RB group up to and including 320-c), where the number of RB groups 320 may be based on the number of RB groups 320 supported by UE 115. The number of RB groups 320 of a CORESET 310 may be based on the capabilities of UE 115 or may be predefined (e.g., based on a wireless communication standard) and stored at base station 105 and / or UE 115.

[0130] In some cases, UE 115 may report its capabilities to the base station, for example, by reporting the number of supported RB groups 320 (e.g., the highest number of supported RB groups 320, as indicated by an index). In some cases, UE 115 may report its type or class to base station 105 (e.g., as indicated by an index), and base station 105 may use the type or class of UE 115 to determine the number of RB groups 320 supported by UE 115. In some cases, the wireless communication standard may define the number of RB groups 320 that the class or type of UE 115 may support (e.g., the highest number of RB groups 320).

[0131] The UE 115 may be configured to refrain from decoding a control channel on a CORESET 310 that includes a number of RB groups 320 that is greater than the number of RB groups 320 supported by the UE 115. For example, in some cases, a CORESET 310-b may be configured with five RB groups 320, and the UE 115 may support one, two, or three RB groups 320, respectively. Thus, the UE 115 may receive the configuration of the CORESET 310-b from the base station 105, may determine that the number of RB groups 320 of the CORESET 310-b is greater than one, two, or three RB groups 320, respectively, and may determine to refrain from decoding a channel on the CORESET 310-b based on the number of RB groups 320 of the CORESET 310-b being greater than the supported number of RB groups 320.

[0132] In some examples, resource configurations 301 and 302 may include examples of reduced complexity CORESETs 310 for control channels associated with wideband or narrowband reference signals. In some cases, the number of RB groups 320 supported by a UE 115 or configured by a base station for a CORESET 310 associated with a narrowband reference signal may be different than for a CORESET 310 associated with a wideband reference signal. For example, a wireless standard may configure the number of supported RB groups 320 based on the type of UE 115 and based on the type of reference signal (e.g., narrowband or wideband). Additionally or alternatively, a UE 115 may report a separate capability for the number of supported RB groups 320 for a CORESET 310 associated with a narrowband reference signal or a wideband reference signal. In some cases, similar methods may be used to determine the number of RB groups 320 supported by the UE 115 or the number of RB groups 320 configured by the base station for a CORESET 310 associated with a narrowband reference signal and a CORESET 310 associated with a wideband reference signal. For example, a CORESET 310 configured with a narrowband reference signal may be associated with the same number of RB groups 320 or the same number of supported RB groups 320 as a CORESET 310 configured with a wideband reference signal.

[0133] In some cases, the UE 115 may be configured (e.g., according to a wireless communication standard) to use the same number of supported RB groups 320 for a CORESET 310 that includes narrowband reference signals as for a CORESET 310 that includes wideband reference signals. For example, the UE 115 may determine that the CORESET 310 that includes narrowband reference signals is associated with the same set of parameters (e.g., the number of RB groups and the number of supported RB groups 320) as the CORESET 310 that includes wideband reference signals, and may thereby determine the set of parameters (e.g., the number of RB groups 320 and the number of supported RB groups 320) for the CORESET 310 that includes narrowband reference signals.

[0134] Figure 4A and Figure 4B 1 and 2 illustrate respective examples of resource configurations 401 and 402 supporting control resource configuration according to aspects of the present disclosure. In some examples, resource configurations 401 and 402 can implement aspects of wireless communication systems 100 or 200. For example, resource configurations 401 and 402 can each include a CORESET 410 configured by base station 105 for UE 115, where base station 105 and UE 115 can be reference Figure 1 and Figure 2 Examples of corresponding devices described. In some examples, UE 115 can be a low-complexity or other type of UE 115.

[0135] Resource configurations 401 and 402 may include an example of a reduced complexity CORESET 410 configured on a time slot 405, as described with reference to FIG. Figure 2 In some cases, the base station 105 may configure the CORESETs 410-a and 410-b to avoid multiplexing symbols (e.g., any symbols) of the CORESET 410 with other signals 420 or channels (e.g., any other signals or channels, such as a physical downlink shared channel (PDSCH) 415). The base station 105 may avoid FDM of a control channel (e.g., a PDCCH 425 on the CORESET 410) with other signals 420 (such as an SSB, a physical broadcast channel (PBCH), a CRS, channel state information (CSI), or any combination thereof). The base station 105 may also avoid FDM of a control channel (e.g., a PDCCH 425 on the CORESET 410) with other channels (such as the PDSCH 415).

[0136] UE 115 may indicate multiplexing capabilities (e.g., FDM capabilities) to base station 105, wherein configuration of reduced complexity CORESET 410 may be based on the multiplexing capabilities. UE 115 may send an explicit indication of its multiplexing capabilities to base station 105, or may additionally or alternatively send an indication of the type or class of UE 115 (e.g., indicated by an index), which base station 105 may use to determine the multiplexing capabilities. In some cases, the wireless communication standard may define the multiplexing capabilities that a class or type of UE 115 may support.

[0137] If the multiplexing capability indicates that the UE 115 is unable to decode a control channel that is multiplexed with one or more other signals 420 or channels (e.g., if the UE 115 is a low complexity UE 115), then in some cases the base station 105 may configure the CORESET 410 to avoid sharing one or more symbols of the CORESET 410 with the one or more other signals 420 or channels. The UE 115 may additionally or alternatively be configured to refrain from decoding a control channel (e.g., a PDCCH 425) that is multiplexed (e.g., partially or completely) with one or more other signals 420 or channels.

[0138] For example, if the base station 105 configures a signal 420-a or 420-b that shares one or more symbols with the CORESET 410-a, the UE 115 may determine that the one or more symbols are shared and may determine not to decode a control channel on the CORESET 410-a based on the shared symbol(s) and the multiplexing capability of the UE 115. Similarly, if the base station 105 configures a PDSCH 415-b that shares one or more symbols with the CORESET 410-b, the UE 115 may determine that the one or more symbols are shared and may determine not to decode a control channel (e.g., PDCCH 425-a) on the CORESET 410-b based on the shared symbol(s) and the multiplexing capability of the UE 115. In some cases, if the base station 105 determines that the UE 115 does not support multiplexing and that the CORESET 410 shares one or more symbols with one or more other signals or control channels, the base station 105 may delay transmission of the PDCCH 425 or control message on the CORESET 410.

[0139] In some cases, before the UE 115 determines that one or more symbols are shared, the PDSCH 415-b may be scheduled for the UE 115 via a control channel (e.g., a control message) on another CORESET 410. In some cases, the PDSCH 415-b may be rate matched around the CORESET 410-b, and in some cases, the PDSCH 415-b may be rate matched around scheduled downlink control information (DCI) or PDCCH 425-a. In some examples, the PDSCH 415-b may share the same activated BWP as the CORESET 410-b.

[0140] If the multiplexing capability indicates that the UE 115 is capable of decoding a control channel that is multiplexed with one or more other signals 420 or channels, then in some cases the base station 105 may configure the CORESET 410 to share one or more symbols (e.g., up to a threshold number of symbols of the UE 115) of the CORESET 410 and the one or more other signals 420 or channels. The UE 115 may additionally or alternatively be configured to decode a control channel (e.g., a PDCCH 425) that is multiplexed (e.g., up to a threshold number of symbols) with one or more other signals 420 or channels (e.g., partially or completely).

[0141] Figure 5 An example of a process flow 500 for supporting control resource configuration according to aspects of the present disclosure is shown. In some examples, the process flow 500 can implement or be implemented by aspects of the wireless communication system 100 or 200. Additionally, the process flow 500 can implement or be implemented by aspects of resource configuration 301, 302, 401, or 402. The process flow 500 can be implemented by a reference Figure 1 4 depicts an example UE 115 and base station 105 implementation of UE 115-c and base station 105-b. Base station 105-b may configure a CORESET for control channel transmission for UE 115-c. In some cases, UE 115-c may represent a low-complexity UE 115.

[0142] The UE 115-c may implement aspects of the process flow 500 to identify the CORESET configured for the UE 115-c and determine whether to decode a control message or control channel on the CORESET, as described with reference to FIG. Figure 2 - as described in FIG4. Similarly, base station 105-b may implement aspects of process flow 500 to configure a CORESET for UE 115-c, as described with reference to FIG4. Figure 2 -4 as described.

[0143] In the following description of process flow 500, operations between UE 115-c and base station 105-b may be presented in a different order than shown, or operations performed by UE 115-c or base station 105-b may be performed in a different order or at a different time. Certain operations may also be omitted from process flow 500, or other operations may be added to process flow 500. Although UE 115-c and base station 105-b are shown as performing the operations of process flow 500, some aspects of some operations may also be performed by one or more other wireless devices.

[0144] At 510, the UE 115-c may send an indication of supported CORESET capabilities to the base station 105-b. The CORESET capabilities may include, but are not limited to, the number of RB groups supported by the UE 115-c for control channels, the multiplexing capability supported by the UE 115-c for control channels, or a combination thereof. In some cases, the UE 115-c may send an explicit indication of the number of supported RB groups or the multiplexing capability. In some cases, the UE 115-c may send an indication of the type or category of the UE 115-c (e.g., indicated by an index), which the base station 105-b may use to determine the supported CORESET capabilities. The UE 115-c may use the CORESET capabilities described herein. Figure 6-Figure 9 The base station 105-b may use a capability indication component as described herein to send an indication of supported CORESET capabilities, wherein the capability indication component may be coupled to or be an example of a transmitter or transceiver. Figure 10-13 The capability receiving component described above receives the indication, wherein the capability receiving component can be coupled to a receiver or a transceiver or be an example of a receiver or a transceiver.

[0145] At 515, the base station 105-b may configure a CORESET for the UE 115-c based on the supported CORESET capabilities of the UE 115-c (e.g., the supported number of RB groups or the multiplexing capability). For example, the base station 105-b may configure the CORESET for the UE 115-c to include a plurality of RB groups based on the supported number of RB groups. Additionally or alternatively, the base station 105-b may configure the CORESET for the UE 115-c to avoid multiplexing with one or more other signals or other channels in any symbol or symbols of the CORESET. The base station 105-b may use a CORESET as described herein. Figure 10-13 The described CORESET configuration component is used to configure the CORESET, where the CORESET configuration component may in some cases be included in code executed by a processor.

[0146] The base station 105-b may also receive the supported CORESET capabilities of the other UE 115 and configure a CORESET for the other UE 115 based on the supported CORESET capabilities of the other UE 115. In some cases, the other UE 115 may be a different type of UE 115 than the UE 115-c (e.g., may be a non-low complexity UE 115), and the base station 105-b may configure the corresponding CORESET accordingly. For example, the base station 105-b may configure the CORESET of the UE 115-c as a reduced complexity CORESET and may configure the CORESET of the other UE 115 without reducing complexity or one or more aspects thereof. The base station 105-b may use a CORESET as described herein with reference to Figure 10-13 The described CORESET configuration component, which in some cases may be included in code executed by a processor, configures a CORESET for another UE 115 .

[0147] At 520, in some cases, the base station 105-b may send an indication of the configured CORESET to the UE 115-c. For example, the base station 105-b may send the CORESET configuration to the UE 115-c via an RRC message. The indication may be sent, for example, as part of an RRC procedure or an initial configuration procedure. In some cases, the indication may include an indication of one or more parameters of the CORESET, such as the number of RB groups. The base station 105-b may send the indication using a transmitter or transceiver as described herein.

[0148] At 525, in some cases, the base station 105-b may schedule a message for the UE 115-c to be carried via one or more other channels based on the multiplexing capabilities of the UE 115-c. For example, if the multiplexing capabilities of the UE 115-c indicate that the UE 115-c does not receive multiplexed signals or channels, the base station 105-b may schedule the message such that the message does not overlap with the CORESET of the UE 115-c (e.g., with any symbol of the CORESET). If the multiplexing capabilities of the UE 115-c indicate that the UE 115-c can receive multiplexed signals or channels, the base station 105-b may schedule the message such that the message may overlap with one or more symbols of the CORESET of the UE 115-c. The base station 105-b may use a method as described herein with reference to Figure 10-13 The described message dispatching component dispatches messages, wherein the message dispatching component may in some cases be included in code executed by a processor.

[0149] At 530, the UE 115-c may identify a CORESET configured by the base station 105-b, wherein the CORESET may be associated with the control channel. In some cases, the UE 115-c may identify the CORESET based on an indication from the base station 105-b. In some cases, the UE 115-c may identify the CORESET based on one or more tables or indexes associated with the UE 115-c, the base station 105-b, the control channel, or any combination thereof. The UE 115-c may identify the CORESET when configured with the CORESET or when preparing to listen to the CORESET. The UE 115-c may use a CORESET configured as described herein. Figure 6-Figure 9 A CORESET identification component is described to identify a CORESET, where the CORESET identification component may in some cases be included in code executed by a processor.

[0150] At 535, the UE 115-c may identify one or more parameters of the CORESET. The one or more parameters may include the number of RB groups of the CORESET. Additionally or alternatively, the one or more parameters may include the number of symbols containing messages carried via one or more other channels multiplexed in frequency with the CORESET. The UE 115-c may compare the one or more parameters of the CORESET with one or more corresponding capabilities of the UE 115-c. The UE 115-c may use the CORESET parameters as described herein. Figure 6-Figure 9 The described CORESET characteristic identification component is used to identify one or more CORESET parameters, where the CORESET characteristic identification component may, in some cases, be included in code executed by a processor.

[0151] At 540, the UE 115-c may determine whether to decode one or more candidates for the search space of the CORESET or whether to decode a control message on the CORESET. The UE 115-c may determine whether to decode the one or more search space candidates based on the multiplexing capabilities of the UE 115-c and whether a message carried via one or more other channels overlaps with any symbol of the CORESET. For example, if the multiplexing capabilities of the UE 115-c are such that the UE 115-c is not configured to receive multiplexed transmissions in the CORESET (e.g., any symbol of the CORESET), and the message overlaps with at least one symbol of the CORESET, the UE 115-c may determine to refrain from decoding the one or more search space candidates. Similarly, if the supported number of RB groups (e.g., supported by the UE 115-c) is less than the number of RB groups of the CORESET, the UE 115-c may determine to refrain from decoding the control message on the CORESET. The UE 115-c may use a multiplexing capability as described herein with reference to Figure 6-Figure 9 The described decoding determination component, which in some cases may be included in code executed by a processor, determines whether to decode one or more search space candidates or a control message.

[0152] At 545, the base station 105-b may send a control message to the UE 115-c on the CORESET. In some cases, the control message may represent or be associated with a control channel (e.g., a PDCCH). The UE 115-c may decode the control message based on determining whether to decode one or more search candidates or based on determining whether to decode the control message. For example, if the message does not overlap with a symbol of the CORESET, or if the number of RB groups of the CORESET is less than or equal to the supported number of RB groups, the UE 115-c may decode the control message. The base station 105-b may use a control message as described herein with reference to Figure 10-13 The control message sending component described herein may be coupled to or be an example of a transmitter or transceiver. The UE 115-c may use a control message sending component as described herein. Figure 6-Figure 9 The described decoding component receives the control message, wherein the decoding component can be coupled to a receiver or a transceiver or can be an example of a receiver or a transceiver.

[0153] Figure 6A block diagram 600 of a device 605 supporting control resource configuration according to aspects of the present disclosure is shown. The device 605 can be an example of aspects of the UE 115 as described herein. The device 605 can include a receiver 610, a communication manager 615, and a transmitter 620. The device 605 can also include a processor. Each of these components can communicate with each other (e.g., via one or more buses).

[0154] The receiver 610 may receive information associated with various information channels (e.g., control channels, data channels, and information related to control resource configuration, etc.), such as packets, user data, or control information. The information may be passed to other components of the device 605. The receiver 610 may be a reference Figure 9 Examples of aspects of the transceiver 920 are described. The receiver 610 may utilize a single antenna or a collection of antennas.

[0155] The communication manager 615 may send an indication of a supported number of RB groups for a control channel to the base station, identify a CORESET associated with the control channel, the CORESET including one or more RB groups, identify the number of the one or more RB groups based on identifying the CORESET, and determine whether to decode a control message on the CORESET based on the supported number of RB groups and the number of the one or more RB groups. The communication manager 615 may also send an indication of multiplexing capability to the base station, identify whether one or more symbols associated with the CORESET including the control channel include a message carried via one or more other channels multiplexed in frequency with the CORESET, and determine whether to decode one or more candidates for a search space for the CORESET based on the multiplexing capability and whether the one or more symbols include the message. The communication manager 615 may be an example of aspects of the communication manager 910 described herein.

[0156] The communication manager 615 or its subcomponents may be implemented in hardware, in code executed by a processor (e.g., software or firmware), or any combination thereof. If implemented in code executed by a processor, the functions of the communication manager 615 or its subcomponents 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 designed to perform the functions described in this disclosure.

[0157] The communication manager 615 or its subcomponents can be physically located at various locations, including being distributed so that portions of the functionality are implemented by one or more physical components at different physical locations. In some examples, according to various aspects of the present disclosure, the communication manager 615 or its subcomponents can be separate and distinct components. In some examples, according to various aspects of the present disclosure, the communication manager 615 or its subcomponents can be combined with one or more other hardware components, including but not limited to input / output (I / O) components, a transceiver, a network server, another computing device, one or more other components described in the present disclosure, or a combination thereof.

[0158] The transmitter 620 can transmit signals generated by other components of the device 605. In some examples, the transmitter 620 can be co-located with the receiver 610 in a transceiver module. For example, the transmitter 620 can be a reference Figure 9 Examples of various aspects of the transceiver 920 are described. The transmitter 620 may utilize a single antenna or a collection of antennas.

[0159] The actions performed herein by the communication manager 615 and the like can be implemented to achieve one or more potential advantages. For example, the communication manager 615 can reduce communication latency and increase available power at a wireless device (e.g., UE 115) by implementing a reduced-complexity CORESET configuration. The reduced-complexity CORESET configuration can reduce processing time at the device or reduce energy consumption (or any combination thereof) compared to, for example, other systems and techniques that do not include a reduced-complexity CORESET configuration. Thus, the communication manager 615 can save energy and increase battery life of a wireless device (e.g., UE 115) by strategically reducing the amount of processing performed by the wireless device (e.g., UE 115).

[0160] Figure 7 A block diagram 700 of a device 705 supporting control resource configuration according to aspects of the present disclosure is shown. The device 705 can be an example of aspects of the device 605 or UE 115 as described herein. The device 705 can include a receiver 710, a communication manager 715, and a transmitter 745. The device 705 can also include a processor. Each of these components can communicate with each other (e.g., via one or more buses).

[0161] The receiver 710 may receive information associated with various information channels (e.g., control channels, data channels, and information related to control resource configuration, etc.), such as packets, user data, or control information. The information may be passed to other components of the device 705. The receiver 710 may be a reference Figure 9 Examples of aspects of the transceiver 920 are described. The receiver 710 may utilize a single antenna or a collection of antennas.

[0162] Communications manager 715 may be an example of aspects of communications manager 615 as described herein. Communications manager 715 may include capability indication component 725, CORESET identification component 730, CORESET characteristic identification component 735, and decoding determination component 740. Communications manager 715 may be an example of aspects of communications manager 910 as described herein.

[0163] Capability indicating component 725 can transmit to the base station an indication of a supported number of RB groups for the control channel.Capability indicating component 725 can additionally or alternatively transmit to the base station an indication of multiplexing capability.

[0164] CORESET identifying component 730 can identify a CORESET associated with a control channel, the CORESET comprising one or more RB groups.

[0165] CORESET characteristics identifying component 735 can identify the number of one or more RB groups based on identifying the CORESET.CORESET characteristics identifying component 735 can identify whether one or more symbols associated with a CORESET comprising a control channel include messages carried via one or more other channels multiplexed in frequency with the CORESET.

[0166] Decoding determination component 740 can determine whether to decode a control message on a CORESET based on the supported number of RB groups and the number of the one or more RB groups.
