Early indications of new radio lightweight dedicated system information

Abstract

Methods, systems, and devices for wireless communications are described. The described techniques involve early indication from a base station to a user equipment (UE) that can allow the UE to determine, from the first symbol of a synchronization signal block (SSB), whether system information associated with the SSB is intended for the UE. Thus, when the UE receives an indication that the system information is dedicated to the UE, the UE can determine to receive and decode the remaining synchronization signal blocks, master information blocks, control resource sets, downlink control channels, and downlink shared channels to receive the system information. In some cases, the UE can determine that the system information is general and end decoding during reception of the SSB to save computational resources by avoiding unnecessary decoding.

[0001] Cross-reference to related applications

[0002] This application claims priority to international patent application number PCT / CN2019 / 122892 of LI et al., filed on December 4, 2019, entitled “EARLY INDICATION OF NEW RADIO LIGHTWEIGHT DEDICATED SYSTEM INFORMATION,” which is assigned to the present assignee and is incorporated herein by reference in its entirety. Technical Field

[0003] The following relates generally to wireless communications and, more particularly, to early indication of new radio lightweight dedicated system information. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, etc. These systems may have the ability to 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 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 of which simultaneously supports communication with multiple communication devices (which may also be referred to as user equipment (UE)).

[0005] In some cases, the UE may perform a synchronization process during initial access to establish a connection via a channel. The UE may receive synchronization signals and system information from the base station. However, the UE may perform multiple steps before receiving the system information. For example, the UE may receive and decode synchronization signal blocks, master information blocks, control resource sets, downlink control channels, and downlink shared channels to receive system information. These synchronization steps may be computationally burdensome on the UE, and conventional techniques for synchronization may have limitations for different types of devices, including those employing coverage enhancement or reduced computational complexity. Summary of the Invention

[0006] The described techniques relate to improved methods, systems, devices, and apparatuses that support early indication of dedicated system information for a first type of user equipment (UE) (e.g., a new radio-lightweight UE, a reduced capability UE, or a low-layer UE). Generally speaking, the described techniques provide an early indication to a UE that can allow the UE to determine, from the first symbol of a synchronization signal block (SSB), whether system information associated with the SSB is intended for the UE. Thus, when a UE receives an indication that system information (e.g., a system information block (SIB), which may include remaining minimum system information (RMSI)) is dedicated to the UE, the UE can determine to receive and decode one or more of a synchronization signal block, a master information block, a control resource set, a downlink control channel, and a downlink shared channel to receive the system information. Additionally or alternatively, the UE can determine that the associated system information is general (e.g., not dedicated to the UE) and terminate decoding during reception of the SSB. Thus, the UE can save computing resources by avoiding unnecessary decoding.

[0007] According to various aspects of the present disclosure, system information may be specific to one type of UE (e.g., a first type such as a low layer or a second type such as a high layer), or may be common to all UE types. The system information may be SIB1 indicating radio resource configuration signaling and may be sent on a downlink shared channel (e.g., a physical downlink shared channel (PDSCH)). The UE may perform a cell search procedure before receiving system information specific to its UE type. The cell search procedure may include an SSB that may include a primary synchronization signal (PSS) in the first symbol period of the SSB. The early indication discussed herein may surround the PSS on one or both sides of the same symbol as the PSS in frequency. The early indication may be a sequence that may allow a low-layer UE to more efficiently determine whether to perform computationally demanding tasks such as decoding the SSB, master information block (MIB), type 0 control resource set (CORESET0), physical downlink control channel (PDCCH), and PDSCH to receive the SIB.

[0008] The UE may be configured to measure lower and higher frequencies around the PSS, including being high, low, or both in frequency. In some cases, the indicator sequence may consist of two parts, each part on a separate set of subcarriers within the same symbol as the PSS of the SSB (e.g., one part at a higher frequency than the PSS and the other part at a lower frequency than the PSS). The two sequence parts may indicate the same information, different information, or form a single joint sequence. For example, the UE may receive the PSS on a first set of subcarriers in a symbol period of the SSB and receive an early system information indication on a second set of subcarriers in the symbol period of the SSB, and determine that the SSB is associated with system information dedicated to the UE based on the presence of the system information indication in the PSS symbol.

[0073] The described techniques relate to improved methods, systems, devices, and apparatuses for supporting early indication of New Radio Lightweight dedicated system information. Generally speaking, the described techniques provide an early indication to a user equipment (UE) that can allow the UE to determine, from the first symbol of a synchronization signal block (SSB), whether system information associated with the SSB is intended for the UE. Thus, when a UE receives an indication that system information (e.g., a system information block (SIB) that may contain residual minimum system information (RMSI)) is intended for the UE, the UE can determine to receive and decode the SSB, master information block (MIB), control resource set (CORESET), downlink control channel, and downlink shared channel to receive the system information. Additionally, the UE can determine that the system information corresponding to the SSB is general (e.g., not dedicated to the UE) and terminate decoding during reception of the SSB. Consequently, the UE can save computational resources by avoiding unnecessary decoding. This early indication method is more computationally friendly for UEs (also known as reduced-capability UEs) than brute-force decoding of all SSBs, MIBs, CORESETs, downlink control channels, and downlink shared channels to receive system information.

[0074] In some examples, the system information may be dedicated to a type of UE, such as a low-layer UE, which may also be referred to as a New Radio (NR)-lightweight UE, a Reduced Capability (RedCap) UE, or a Premium UE. The low-layer UE may operate with one or more of: reduced transmit power, a reduced number of transmit and / or receive antennas, a reduced transmit / receive bandwidth, or reduced computational complexity. For example, the low-layer UE may be a smart wearable device, an industrial sensor, or a video surveillance device. The described technology provides a method for a base station to indicate in an SSB whether a SIB is for an NR-lightweight UE, which can reduce the need for the NR-lightweight UE to use brute force to decode all decodable SSBs to obtain all SIB1s on all available SSBs to find the NR-lightweight-specific SIB1 configuration.

[0075] In some examples, the system information may be specific to one type of UE (e.g., a low-layer type or a premium type) or may be common to all UE types. The system information may be SIB1 indicating radio resource configuration signaling and may be sent on a downlink shared channel, e.g., a physical downlink shared channel (PDSCH). The UE may perform a cell search procedure before receiving system information specific to its UE type. For example, the UE may tune to the frequency of the cell and then attempt to receive and decode the SSB. More specifically, the SSB may include a primary synchronization signal (PSS) in the first symbol period of the SSB. The early indication discussed herein may surround the PSS on one or both sides in the same symbol as the PSS on the frequency. The early indication may be a sequence that may allow the NR-lightweight UE to more efficiently determine whether to perform computationally demanding tasks such as decoding the SSB, MIB, type 0 CORESET (CORESET0), physical downlink control channel (PDCCH), and PDSCH to receive the SIB.

[0076] According to aspects of the present disclosure, a UE may be configured to measure lower and higher frequencies around the PSS of an SSB for early indication. In some cases, the indication sequence may consist of two parts, each part being on a separate set of subcarriers within the same symbol as the PSS of the SSB (e.g., one part being at a higher frequency than the PSS and the other part being at a lower frequency than the PSS). The two sequence parts may indicate the same information, different information, or form a single joint sequence. For example, a UE may receive a PSS on a first set of subcarriers in a symbol period of an SSB and receive an early system information indication on a second set of subcarriers in a symbol period of an SSB, and determine that the SSB is associated with system information dedicated to the UE based on the presence of the system information indication in the PSS symbol. Accordingly, the UE may continue to decode the physical broadcast channel (PBCH) and secondary synchronization signal (SSS), control resources, system information, etc. of the SSB based on determining that the SSB is associated with system information dedicated to the UE.

[0077] The early indication in question may be in the same symbol period as the PSS of the SSB (which may be in the first symbol of the SSB), and thus may allow NR-light UEs to avoid increasing the amount of unnecessary decoding of the SSB as well as the PBCH and SSS in the MIB, PDCCH, and SIB (e.g., SIB1) when the SIB is not intended for NR-light UEs. The indication may include one or more sequences adjacent to the PSS in frequency (the sequences may be orthogonal or low-correlated). In addition, those NR-light-specific SSBs with NR-light SIBs may be designed to reduce the computational complexity of NR-light UEs.

[0078] In some cases, if no indicator sequence is detected, the NR-lightweight UE may determine that no NR-lightweight dedicated SIB is associated with the corresponding SSB. As a result, the UE may terminate decoding of the SSB. In some examples, different sequences may allow the NR-lightweight UE to identify the presence or absence of an NR-lightweight dedicated SIB. Additionally or alternatively, the early indication may also identify a subcategory of NR-lightweight dedicated SIB1 and / or CORESET0.

[0079] Aspects of the present disclosure are initially described in the context of wireless communication systems.Aspects of the present disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flow diagrams related to early indication of new radio lightweight dedicated system information.

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.

[0081] 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 a UE 115 and base station 105 may establish one or more communication links 125. Coverage area 110 may be an example of a geographic area over which base stations 105 and UEs 115 may support communication of signals according to one or more radio access technologies.

[0082] 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 with different capabilities. Figure 1 Some example UEs 115 are shown in FIG. Figure 1As shown in , the UE 115 described herein may be 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).

[0083] 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), 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.

[0084] One or more of the base stations 105 described herein may include or may be referred to by a person of ordinary skill in the art as a base station transceiver, a wireless base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB, evolved NodeB), a next generation NodeB or a gigabit NodeB (any of which may be referred to as a gNB), a home nodeB, a home evolved nodeB or other appropriate terminology.

[0085] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where a "device" may also be referred to as a unit, a station, a terminal, or a client, among other examples. UE 115 may also include or may 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, among other examples, which may be implemented in various objects, such as appliances, or vehicles, meters, and other examples.

[0086] like Figure 1 As shown in , the UE 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as base stations 105 and network devices (including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples).

[0087] The UE 115 and the base station 105 can communicate wirelessly with each other via one or more communication links 125 on one or more carriers. The term "carrier" can refer to a set of radio frequency spectrum resources with a defined physical layer structure for supporting the communication link 125. For example, a carrier for the communication link 125 can include a portion of a radio frequency spectrum band (e.g., a bandwidth portion (BWP)) that operates 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 can carry acquisition signaling (e.g., synchronization signals, system information), control signaling to coordinate the operation of the carrier, user data, or other signaling. The wireless communication system 100 can use carrier aggregation or multi-carrier operation to support communication with the UE 115. The UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation can be used with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0088] The signal waveform transmitted on 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 related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements received by the UE 115 and the higher the order of the modulation scheme, the higher the data rate for the UE 115 may be. Wireless communication resources may indicate a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may further increase the data rate or data integrity for communications with the UE 115.

[0089] 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.

[0090] The time intervals of the base station 105 or the UE 115 may be expressed in multiples of a basic time unit, which may indicate, for example, T s =1 / (Δf max ·Nf ) 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).

[0091] 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 number 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 the cyclic prefix preceding each symbol period). In some wireless communication systems 100, a time slot may be further divided into a plurality of mini-slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N f ) sampling period. The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0092] 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 bursts of shortened TTIs (sTTIs)).

[0093] Physical channels may be multiplexed on a carrier according to various techniques. Physical control channels and physical data channels may be multiplexed on a downlink carrier, for example, using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by multiple symbol periods and may extend across the system bandwidth of a carrier or a subset of the system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more of UEs 115 may monitor or search the control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate may indicate 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. The search space sets may 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 .

[0094] In some examples, base stations 105 can be mobile and, therefore, 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.

[0095] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or with a base station 105 without human intervention. In some examples, M2M communication or MTC may include communications from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application that utilizes the information or presents it to a person interacting with the application. Some UEs 115 may be designed to collect information or implement automated behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based billing for services.

[0096] 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 UEs 115 include entering a power-saving deep sleep mode when not engaged in active communications, 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 that is 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.

[0097] 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 (e.g., 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.

[0098] In some examples, UE 115 may also be able to 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 may be within the geographic coverage area 110 of base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of base station 105 or otherwise unable to receive transmissions from base station 105. In some examples, a group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, in which each UE 115 transmits to each other UE 115 in the group. In some examples, base station 105 facilitates scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without involving base station 105.

[0099] In some systems, the D2D communication link 135 can be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicles can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these. The vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, vehicles in a V2X system can communicate with roadside infrastructure (such as roadside units), or communicate with the network via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communication, or communicate with both.

[0100] 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) and may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) that manages access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) that routes packets or interconnections to external networks. The control plane entities 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 transmitted via the user plane entities, which may provide IP address allocation and other functions. The user plane entities may connect to network operator IP services 150. The network operator IP services 150 may include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or packet-switched streaming services.

[0101] Some 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).

[0102] 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). Typically, 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 in length from approximately one decimeter to one meter. UHF waves can be blocked or redirected by buildings and environmental features, but the waves can penetrate structures sufficiently for a macrocell to provide service to a UE 115 located indoors. Transmissions using UHF waves can be associated with smaller antennas and a shorter range (e.g., less than 100 kilometers) than transmissions using the lower frequencies and longer wavelengths of the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0103] The wireless communication system 100 may also operate in the super high frequency (SHF) region (also known as the centimeter band) using frequency bands from 3 GHz to 30 GHz, or in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also known as the millimeter band). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between the UE 115 and the base station 105, and the EHF antennas of each device may be smaller and more closely spaced than the UHF antennas. In some examples, this may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may be subject to 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 designated use of frequency bands across these frequency regions may vary by country or regulatory body.

[0104] The wireless communication system 100 can utilize both licensed and unlicensed radio frequency 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 frequency spectrum band, devices (such as base stations 105 and UEs 115) can employ carrier sensing for conflict detection and avoidance. In some examples, operations in an unlicensed band can be based on a carrier aggregation configuration combined 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 other examples.

[0105] The base station 105 or UE 115 may be equipped with multiple antennas that can 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 that can 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 having multiple rows and columns of antenna ports that the base station 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0106] 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 conveyed 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 conveyed via antenna elements can include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each of the antenna elements 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).

[0107] UE 115 and base station 105 can support retransmission of data to increase the likelihood that the data is successfully received. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the likelihood of correctly receiving data on communication link 125. HARQ can include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ can improve the throughput at the medium access control (MAC) layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, a device can support same-slot HARQ feedback, wherein the device can provide HARQ feedback for data received in previous symbols in the slot in a specific slot. In other cases, the device can provide HARQ feedback in subsequent slots or according to some other time interval.

[0108] In some examples, the UE 115 may monitor the first symbol of the SSB for the PSS and a system information (SI) indication to determine whether the SSB is associated with SI that is dedicated to the UE 115 (e.g., based on the type of UE 115). Example UE types may include NR-light UEs 115 (which may also be referred to as reduced capability (RedCap) UEs 115) or premium UEs 115. The SI indication may include a sequence that fills the subcarriers residing on both sides of the PSS. The two SI indication portions may together form a single sequence, or more than one sequence may be formed on each side separately. The base station 105 may generate an SI indication for the SSB that indicates that the SSB is associated with SI that is dedicated to the first type of UE 115. The SI indication may allow for more efficient operation of the NR-light UE 115.

[0109] The premium UE 115 may use the SSB associated with the NR-lightweight dedicated SIB, or the premium UE 115 may ignore the SSB associated with the NR-lightweight dedicated SIB and use a different premium or universal SSB. When an SI indication is detected using the PSS, the NR-lightweight UE 115 may proceed with synchronization and decoding of the SSB associated with the NR-lightweight dedicated SIB. Alternatively, the NR-lightweight UE 115 may not proceed with synchronization and decoding of SSBs not associated with the NR-lightweight dedicated SIB. Thus, when the NR-lightweight dedicated SIB is not present, the NR-lightweight UE 115 may save power by avoiding unnecessary decoding computations.

[0110] The example techniques described with reference to NR-lightweight UEs 115 and premium UEs 115 may be applied in other examples to distinguish between UEs of other types, categories, classes, etc. For example, the example techniques may be applied to any first type of UE 115 and any second type of UE 115, including additional types of UEs (e.g., third or fourth types of UEs 115).

[0111] Figure 2 An example of a wireless communication system 200 that supports early indication of new radio lightweight dedicated system information 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. The wireless communication system 200 can include a base station 105-a and UEs 115-a and 115-b, which can be respectively as shown in FIG. Figure 1 An example of a base station 105 and a UE 115 is depicted. The base station 105-a and the UEs 115-a and 115-b may be configured to use early indications of dedicated system information communicated in the SSB 230.

[0112] Base station 105-a may be an NR base station that communicates with UEs 115-a and 115-b within coverage area 110-a via link 205. In some examples, UE 115-a may be a first type of UE and UE 115-b may be a second type of UE. For example, UE 115-a may be a reduced capability UE. The first type of UE may be associated with a number of receive antennas that is lower than a receive antenna threshold. In some cases, the first type of UE may be associated with a number of receive or transmit antennas that includes a receive or transmit antenna power loss, respectively, that is higher than an antenna gain loss threshold. In some other examples, the first type of UE may be associated with a time-ON duration that is lower than a time-ON threshold, a processing timeline capability that is lower than a processing timeline capability threshold, a maximum transmit power that is lower than a maximum transmit power threshold, a maximum bandwidth that is lower than a maximum bandwidth threshold, or some combination thereof.

[0113] Base station 105-a may transmit at least one SSB 230 to UEs 115-a and 115-b. SSB 230 may be used by UE 115 to synchronize with a cell (e.g., base station 105-a). SSB 230 may include four OFDM symbols (symbol periods). The first symbol may include one or more SI indications 210 and PSS 215. In some examples, PSS 215 may occupy 127 subcarriers. One or more SI indications 210 may fill up to the remaining subcarriers, e.g., 20 resource blocks (RBs). In other examples, one or more SI indications 210 may occupy a subset of the remaining subcarriers, e.g., leaving a buffer or demarcation in frequency between SI indication 210 and PSS 215. The second and fourth symbols may include PBCH 220-a and 220-d, respectively, and each PBCH 220-a and 220-d may span 20 RBs. The third symbol may include two PBCH parts 220 - b (each PBCH part spanning 4 RBs) and 220 - c and an SSS 225 that may occupy 127 subcarriers.

[0114] In some cases, the SSB 230 may be a cell-defining SSB. For example, within the frequency span of a carrier, multiple SSBs 230 may be sent by the base station 105-a to the UEs 115-a and 115-b. The physical cell identifier (PCI) of the SSBs 230 sent in different frequency locations does not have to be unique to the cell. Therefore, the PCI may not be the same, and different SSBs in the frequency domain may have different PCIs. When the SSB 230 is associated with the remaining minimum system information (RMSI), the SSB 230 may correspond to an individual cell, which may have a unique NR cell global identifier (NCGI). Such an SSB 230 with a unique NCGI may be referred to as a cell-defining SSB. In some cases, cell selection and / or reselection of the UE 115 may be based on one or more reference signal received power (RSRP) or reference signal received quality (RSRQ) measurements of the cell-defining SSBs.

[0115] After UE 115 receives SSB 230, UE 115 may decode the SSB to identify the MIB. The MIB may indicate the CORESET and synchronization signal configuration, which may allow UE 115 to receive and decode the PDCCH. The PDCCH may indicate the PDSCH to UE 115, which may include SIBs, which include RMSI. In some cases, a first type of UE, such as a low-layer UE 115-a (e.g., an NR-lightweight UE 115-a, which may be referred to as a reduced capability UE 115-a) may include lower UE capabilities compared to a second type of UE (e.g., a premium UE (e.g., UE 115-b)), and some additional radio resource control (RRC) parameters specific to NR-lightweight UE 115-a may be useful in the SIB (e.g., SIB1) to allow UE 115-a to make successful initial access. For example, a low-layer UE 115-a may request different types of physical random access channel (PRACH) procedures, preamble formats, or repetition levels for the physical uplink shared channel (PUSCH) and physical downlink shared channel (PDSCH), which may require dedicated RRC configuration via SIB1 (e.g., NR-Lightweight dedicated SIB1).

[0116] In some cases, it may not be possible to include NR-lightweight-specific SIB1 for all SSBs 230, or at least for all base stations 105. For example, depending on the network implementation, some SSBs 230 within the entire bandwidth may be available for premium UEs (e.g., UE 115-b). Therefore, SIB1 may indicate parameters that are not suitable for NR-lightweight UEs (e.g., UE 115-a). In some cases, the base station 105 may not include NR-lightweight-specific SIB1 parameters. If the SSBs 230 do not include NR-lightweight-specific SIB1, it would be beneficial if there were no NR-lightweight-specific SIB1 to indicate to the NR-lightweight UE (e.g., UE 115-a). Thus, by avoiding a computationally heavy process for such a power-limited UE 115, using an early indication (e.g., SI indication 210) allows UE 115-a to avoid using a brute force approach to decode all decodable SIBs (e.g., across all available SSBs 230 and / or base stations 105) to find the NR-lightweight dedicated SIB1 configuration, which is beneficial to UE 115-a.

[0117] The SI indication 210 may provide an early indication of the presence of an NR-lightweight-specific configuration (e.g., a dedicated SIB1 and / or CORESET configuration) for the UE 115-a. Furthermore, the SI indication 210 may include sequence-based symbols of where previously empty carriers are included within the SSB 230. For example, the SI indication 210 may reside in higher and lower frequencies around the PSS 215 within the first symbol of the SSB 230. The y-axis of the SSB 230 may show frequency, while the x-axis shows time. Including the SI indication 210 may provide lower computational complexity and, therefore, reduce power consumption for the NR-lightweight UE 115-a, as the NR-lightweight UE 115-a may not have to resort to brute force to decode the MIB and SIB1 and find the appropriate SSB for initial access.

[0118] UEs 115-a and 115-b may monitor 20 RBs (or one or more subsets of the 20 RBs) in the first symbol of PSS 215 and SSBs 230 on either side of PSS 215 for SI indication 210. SI indication 210 may include sequence-based symbols, and subcarriers residing on either side of PSS 215 (SI indications 210-a and 210-b) may jointly form a single sequence or separately form more than one sequence on each side. In some examples, if two sequences can be identified from SI indication 210-a—relative to an upper edge (e.g., higher frequency) of PSS 215—and SI indication 210-b—relative to a lower edge (e.g., lower frequency) of PSS 215, SI indications 210-a and 210-b may provide the same or different information. The sequences of SI indications 210 - a and 210 - b and their association with the presence and optional structure of SIB1 may be stored at the UEs 115 - a and 115 - b and the base station 105 - a .

[0119] If UE 115-b is a premium UE and SSB 230 is associated with an NR-light dedicated SIB, premium UE 115-b may use SSB 230 or ignore SSB 230 and instead use premium or generic SSB 230. If UE 115-a is a low-layer NR-light UE and SSB 230 is associated with an NR-light dedicated SIB, UE 115-a may proceed with synchronization and decoding of SSB 230. Alternatively, if UE 115-a is a low-layer NR-light UE and SSB 230 is not associated with an NR-light dedicated SIB, UE 115-a may not proceed with synchronization and decoding of SSB 230 (e.g., terminate decoding of the second symbol PBCH 220-a).

[0120] Figure 3An example of a synchronization signal block configuration 300 that supports early indication of new radio lightweight dedicated system information according to aspects of the present disclosure is shown. In some examples, the synchronization signal block configuration 300 can implement aspects of the wireless communication system 100. The synchronization signal block configuration 300 can include at least one SSB 305, for example, six SSBs 305 are shown. The SSBs can be sent from the base station 105 to the UE 115, as described above with reference to Figure 2 described.

[0121] SSB 305 is shown with frequency along the y-axis and time along the x-axis. In some cases, an SSB burst comprising multiple SSBs 305 can be time division multiplexed (TDM) or frequency division multiplexed (FDM). TDM SSBs 305 can be spread out at the same frequency in time, while FDM SSBs 305 can be spread out at the same time in frequency. For example, SSBs 305-a, 305-b, and 305-c can be FDM in a first time period, while SSBs 305-d, 305-e, and 305-f can be FDM in a subsequent time period. SSBs 305-a and 305-d can be TDM in a first frequency, while SSBs 305-b and 305-e can be TDM in a second, lower frequency, and so on for SSBs 305-c and 305-f. Each SSB 305 may include a PSS 315 in a first symbol, a PBCH 320-a in a second symbol, an SSS 325 and PBCHs 320-b and 320-c in a third symbol, and a PBCH 320-d in a fourth symbol. Additional or fewer symbols may be present in an SSB 305. In some cases, the SI indication 310 may fill in at least some of the subcarriers in the first symbol that are not used by the PSS 315. For example, the SI indication 310-a may occupy a set of subcarriers at a higher frequency than the PSS 315, and / or the SI indication 310-b may occupy a set of subcarriers at a lower frequency than the PSS 315.

[0122] In some cases, UE 115 may monitor the bandwidth of PBCH 320-a and 320-d in the first symbol of SSB 305 for PSS 315 and both sides of PSS 315 for SI indication 210. SI indication 210 may include sequence-based symbols, and the subcarriers residing on both sides of PSS 315 (SI indication 310-a and 310-b) may jointly form a single sequence or separately form more than one sequence on each side. In some examples, if two sequences can be identified from SI indication 310-a and SI indication 310-b, SI indication 210-a and 210-b may provide the same or different information.

[0123] In some examples, there may be at least two methods for UE 115 to determine that no dedicated SI for the UE is associated with SSB 305. For example, UE 115 may monitor the first symbol of SSB 305-a and receive SI indication 310 and PSS 315. SI indication 310 may convey that no dedicated SI is associated with SSB 305-a. In another example, UE 115 may monitor the first symbol of SSB 305-c and receive PSS 315 but not SI indication. Based on the absence of SI indication in the first symbol of SSB 305-c, UE 115 may determine that no dedicated SI is associated with SSB 305-c. In both cases, UE 115 may terminate decoding of SSB 305.

[0124] UE 115 may monitor the first symbol of SSB 305-b and receive SI indication 310 and PSS 315. SI indication 310 may convey that dedicated SI is associated with SSB 305-b. Different sequences of SI indication 310 may allow UE 115 (e.g., an NR-lightweight UE, which may also be referred to as a reduced capability UE) to identify the presence and / or absence of NR-lightweight dedicated SIBs and, optionally, a subclass of NR-lightweight dedicated SIB1 or CORESET0. In some examples, the subclass may include one or more of the following: a supported repetition level for downlink or uplink, or both; a CORESET (e.g., CORESET0) and SSB multiplexing type (e.g., FDM or TDM); and a bandwidth-related class that may include a frequency domain range and / or frequency domain offset for a dedicated CORESET, as compared to SSB 305. These class indications may help UE 115 determine whether its bandwidth, power, and antenna capabilities can support decoding of such a CORESET or preamble transmission.

[0125] One or more SSBs 305 may be NR light cell definition (CD) SSBs 305. In other words, an SSB 305 associated with an NR light dedicated SIB carrying the same NCGI as the general cell definition SSB 305 is also located on the synchronization raster. In some examples, cell selection / reselection for an NR light UE 115 may be based on reference signal measurements (e.g., RSRP or RSRQ) of the NR light CD-SSB.

[0126] In some cases, the SI indicator sequence 310 may include the following reference Figure 4The multi-level structure described. Additionally or alternatively, the sequence of SI indications 310 may include a direction and frequency range indication of the NR-light cell defining SSB 305. The sequence of SI indications 310 may provide side information about the direction or offset (e.g., frequency or time) of the next available NR light cell defining SSB 305. In some examples, if the SSB 305 is not an NR light cell defining SSB 305, for example, if the SSB 305 is not associated with an NR-light dedicated SIB, the sequence of SI indications 310-a on the upper edge (at a higher frequency than the PSS 315) may indicate the relative direction of the NR light cell defining SSB, and the sequence of SI indications 310-b on the lower edge (at a lower frequency than the PSS 315) indicates the frequency domain offset (e.g., on the SYNC grid) of the NR-light cell defining SSB 305.

[0127] For example, SSB 305-b may be associated with or not associated with an NR-lightweight SIB, and the SI indication 310-a sequence of SSB 305-b may indicate the relative direction of an NR-lightweight cell-defining SSB 305-d (e.g., time and frequency relative to SSB 305-b). Additionally or alternatively, the SI indication 310-b sequence of SSB 305-b may indicate a frequency domain offset of the NR-lightweight cell-defining SSB 305-d. In another example, SSB 305-e may be associated with or not associated with an NR-lightweight SIB, and the SI indication 310-a sequence of SSB 305-e may indicate the relative direction of an NR-lightweight cell-defining SB 305-f (e.g., frequency relative to SSB 305-e).

[0128] In some cases, there may be multiple types of cell-defining SSBs 305 and non-cell-defining SSBs 305. For example, SSB 305-a may be a cell-defining SSB for premium UEs, SSB 305-b may be cell-defining for NR-light UEs, SSB 305-f may be a non-cell-defining SSB for premium UEs, and SSB 305-c may be a non-cell-defining SSB for NR-light UEs. An SI indication 310 may be included with the PSS 315 for all types of SSBs. In some cases, an SI indication 310 may not be included with the PSS 315 for SSB 305-c, which is a non-cell-defining SSB for NR-light UEs.

[0129] Figure 4An example of a multi-stage sequence 400 supporting early indication of new radio lightweight dedicated system information in accordance with aspects of the present disclosure is shown. In some examples, the multi-stage sequence 400 can implement aspects of the wireless communication system 100.

[0130] In some examples, the SI indication may be a sequence similar to an adjacent PSS sequence in an SSB. For example, the sequence may be an m-sequence or a Zadoff-Chu sequence. In other examples, other sequences may be used to provide the indication. In some examples, any sequence that is detectable by the UE and that is suitable for an RB (e.g., 20 RBs or less in size) and that is adjacent to the PSS in frequency to provide an indication may be used to convey the indication. Figure 4 As shown, one or more sequences may include multiple levels of structure or form a hierarchical structure.

[0131] Starting from the most significant bit (MSB) of the sequence, the first sequence portion 405 may include at least one bit (e.g., 0 or 1), where 0 may indicate that there is no NR-light dedicated SIB associated with the SSB carrying the SI indication, and 1 may indicate that there is an NR-light dedicated SIB associated with the SSB carrying the SI indication. In the absence of an NR-light dedicated SIB, the remainder of the sequence (such as the third sequence portion 415 comprising 4 bits) may be empty or reserved.

[0132] When the first sequence portion 405 indicates the presence of an NR-lightweight dedicated SIB, the second sequence portion may include at least one bit and may indicate a repetition level for uplink and / or downlink communications. For example, 1 may indicate a repetition level less than or equal to 4, and 0 may indicate a repetition level greater than 4. The fourth sequence portion 420 may follow the second sequence portion 410 and may include at least two bits indicating a frequency domain range of the NR-lightweight dedicated CORESET relative to the frequency domain range of the SSB containing the indication. For example, 00 may indicate a frequency range that is 8 PRBs lower in frequency than the SSB, 01 may indicate a frequency range that is 4 PRBs higher in frequency than the SSB, 10 may indicate a frequency range that is 28 PRBs higher in frequency than the SSB, and 11 may indicate a frequency range that is 72 PRBs higher in frequency than the SSB.

[0133] Figure 5 An example of a process flow 500 for supporting early indication of new radio lightweight dedicated system information according to aspects of the present disclosure is shown. In some examples, the process flow 500 can implement aspects of the wireless communication system 100. The process flow 500 is shown as being implemented by a UE 115c and a base station 105-b, which can be as described with respect to FIG. Figure 1 and 2Examples of UE 115 and base station 105 are described. For example, UE 115c may be Figure 2 UE 115a, and base station 105-b may be Figure 2 Example of base station 105a.

[0134] In the following description of process flow 500, the operations of UE 115 c and base station 105 - b may occur in an order different from the exemplary order shown. Some of the illustrated operations may also be omitted from process flow 500, or other operations may be added to process flow 500. It should be understood that although UE 115 c and base station 105 - b are shown as performing many of the operations of process flow 500, any wireless device may perform the illustrated operations.

[0135] At 505, the base station 105-b may generate an SI indication of an SSB, the SI indication indicating that the SSB is associated with system information (e.g., SIB) of a first type of UE (e.g., a low-layer UE, a reduced capability UE, etc.). In some cases, the system information indication includes one or more sequences. For example, one or more subcarriers at a higher frequency form a first sequence in the one or more sequences, and one or more subcarriers at a lower frequency form a second sequence in the one or more sequences. In some examples, the first sequence indicates a value of a first parameter associated with the system information, the control resource set, or both (e.g., a direction of a cell-defining synchronization signal block relative to a primary synchronization signal), and the second sequence indicates a value of a second parameter associated with the system information, the control resource set, or both (a frequency offset of a cell-defining synchronization signal block relative to a primary synchronization signal).

[0136] At 510, the base station 105-b may transmit a primary synchronization signal (PSS) on a first set of subcarriers and a system information (SI) indication on a second set of subcarriers in a first symbol period of a synchronization signal block, and the UE 115-c may receive the primary synchronization signal (PSS) on the first set of subcarriers and the system information (SI) indication on the second set of subcarriers in the first symbol period of the synchronization signal block. In some examples, the base station 105-b may transmit one or more subcarriers at a higher frequency than the PSS, or one or more subcarriers at a lower frequency than the PSS, or both, and the UE 115-c may receive one or more subcarriers at a higher frequency than the PSS, or one or more subcarriers at a lower frequency than the PSS, or both.

[0137] At 515, UE 115-c may determine, in response to receiving the system information indication, that the SSB is associated with system information specific to the first type of UEs. Thus, the presence of the system information indication indicates that the SSB is associated with system information specific to the first type of UEs.

[0138] At 520 , based on the PSS, the base station 105 - b may send the PBCH signal and the SSS in the second one or more symbol periods of the SSB, and the UE 115 - c may receive the PBCH signal and the SSS in the second one or more symbol periods of the SSB.

[0139] At 525, UE 115-c may decode the PBCH signal of the SSB based on determining from the SI indication that the system information is dedicated to the first type of UE. In some cases, UE 115-c may also decode a set of control resources dedicated to the first type of UE based on the SSB and based on determining that the system information is dedicated to the first type of UE.

[0140] At 530, the base station 105-b may transmit a SIB specific to the first type of UEs, and the UE 115-c may receive the SIB specific to the first type of UEs. For example, the SIB may be SIB1 carried by the PDSCH.

[0141] At 535, UE 115-c may, based at least in part on determining that the SSB is associated with system information specific to the first type of UEs, decode the system information based at least in part on the PBCH signal in the second one or more symbol periods of the SSB. In some cases, decoding the system information is based on decoding the PBCH signal and the control resource set.

[0142] Figure 6 A block diagram 600 illustrates a device 605 that supports early indication of new radio lightweight dedicated system information according to aspects of the present disclosure. The device 605 may be an example of aspects of the UE 115 as described herein. The device 605 may include a receiver 610, a communication manager 615, and a transmitter 620. The device 605 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0143] The receiver 610 may receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to early indications of new radio lightweight dedicated system information, etc.). The information may be passed to other components of the device 605. The receiver 610 may be a reference Figure 9 Examples of various aspects of the transceiver 920 are described. The receiver 610 may utilize a single antenna or a group of antennas.

[0144] The communication manager 615 may receive a primary synchronization signal on a first subcarrier set and a system information indication on a second subcarrier set in a first symbol period of a synchronization signal block, determine, in response to receiving the system information indication, that the synchronization signal block is associated with remaining minimum system information specific to the first type of UE, and decode the remaining minimum system information based on a physical broadcast channel signal in a second one or more symbol periods of the synchronization signal block based on the determination that the synchronization signal block is associated with the remaining minimum system information specific to the first type of UE. The communication manager 615 may be an example of aspects of the communication manager 910 described herein.

[0145] 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 designed to perform the functions described in this disclosure, discrete gate or transistor logic, discrete hardware components, or any combination thereof.

[0146] 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 aspects of the present disclosure, the communication manager 615 or its subcomponents can be separate and distinct components. In some examples, according to 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.

[0147] 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 group of antennas.

[0148] Figure 7A block diagram 700 illustrates a device 705 supporting early indication of new radio lightweight dedicated system information according to aspects of the present disclosure. The device 705 may be an example of aspects of the device 605 or UE 115 as described herein. The device 705 may include a receiver 710, a communication manager 715, and a transmitter 735. The device 705 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0149] The receiver 710 may receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to early indications of new radio lightweight dedicated system information, etc.). 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 group of antennas.

[0150] Communication manager 715 may be an example of aspects of communication manager 615 as described herein. Communication manager 715 may include early indication identifier 720, SSB manager 725, and system information controller 730. Communication manager 715 may be an example of aspects of communication manager 910 as described herein.

[0151] The early indication identifier 720 may receive a primary synchronization signal on a first set of subcarriers and a system information indication on a second set of subcarriers in a first symbol period of a synchronization signal block.

[0152] The SSB manager 725 may determine, in response to receiving the system information indication, that the synchronization signal block is associated with the remaining minimum system information specific to the first type of UEs.

[0153] The system information controller 730 may decode the remaining minimum system information based on the physical broadcast channel signal in the second one or more symbol periods of the synchronization signal block based on determining that the synchronization signal block is associated with the remaining minimum system information dedicated to the first type of UE.

[0154] The transmitter 735 can transmit signals generated by other components of the device 705. In some examples, the transmitter 735 can be co-located with the receiver 710 in a transceiver module. For example, the transmitter 735 can be a reference Figure 9 Examples of various aspects of the transceiver 920 are described. The transmitter 735 can utilize a single antenna or a group of antennas.

[0155] Figure 8A block diagram 800 illustrates a communication manager 805 that supports early indication of new radio lightweight dedicated system information in accordance with aspects of the present disclosure. The communication manager 805 may be an example of aspects of the communication manager 615, the communication manager 715, or the communication manager 910 described herein. The communication manager 805 may include an early indication identifier 810, an SSB manager 815, a system information controller 820, a PBCH manager 825, a CORESET manager 830, a decoder controller 835, and a cell selection component 840. Each of these modules may communicate with each other directly or indirectly (e.g., via one or more buses).

[0156] The early indication identifier 810 may receive a primary synchronization signal on a first subcarrier set and a system information indication on a second subcarrier set in a first symbol period of a synchronization signal block. In some examples, the early indication identifier 810 may determine that the remaining minimum system information is dedicated to the first type of UE based on the system information indication. In some examples, the early indication identifier 810 may determine one or more characteristics of the remaining minimum system information dedicated to the first type of UE, the control resource set dedicated to the first type of UE, or a combination thereof based on the system information indication, wherein the one or more characteristics include: a repetition level, a multiplexing type between the synchronization signal block and the control resource set dedicated to the first type of UE, a bandwidth category, or a combination thereof. In some examples, the bandwidth category includes a frequency range of the control resource set dedicated to the first type of UE, a frequency offset of the control resource set dedicated to the first type of UE relative to the synchronization signal block, or a combination thereof.

[0157] In some examples, the early indication identifier 810 may determine that the remaining minimum system information is universal based on the system information indication. In some examples, the early indication identifier 810 may monitor the primary synchronization signal and the system information indication in the first symbol period of the second synchronization signal block. In some examples, the early indication identifier 810 may detect that the system information indication is not present in the second synchronization signal block. In some examples, the early indication identifier 810 may receive one or more subcarriers at a higher frequency than the primary synchronization signal, one or more subcarriers at a lower frequency than the primary synchronization signal, or a combination thereof. In some cases, the system information indication includes one or more sequences. In some examples, the early indication identifier 810 may compare the one or more sequences with a stored sequence set to determine that the system information indication is for the UE.

[0158] In some cases, one or more subcarriers at a higher frequency form a first sequence in one or more sequences, and one or more subcarriers at a lower frequency form a second sequence in one or more sequences. In some cases, the first sequence indicates a value of a first parameter associated with the remaining minimum system information, a control resource set dedicated to a first type of UE, or a combination thereof, and the second sequence indicates a value of a second parameter associated with the remaining minimum system information, a control resource set dedicated to a first type of UE, or a combination thereof. In some cases, the value of the first parameter or the value of the second parameter indicates a direction of a cell-defining synchronization signal block dedicated to the first type of UE relative to a primary synchronization signal. In some cases, the value of the first parameter or the value of the second parameter indicates a frequency offset of the cell-defining synchronization signal block dedicated to the first type of UE relative to the primary synchronization signal. In some cases, the first sequence and the second sequence indicate the same value of a parameter associated with the remaining minimum system information, a control resource set dedicated to the first type of UE, or a combination thereof. In some cases, the one or more subcarriers at the higher frequency and the one or more subcarriers at the lower frequency form a joint sequence. In some cases, the one or more sequences include a multi-stage structure.

[0159] The SSB manager 815 may determine, in response to receiving the system information indication, that the synchronization signal block is associated with the remaining minimum system information specific to the first type of UEs.

[0160] The system information controller 820 may decode the remaining minimum system information based on the physical broadcast channel signal in the second one or more symbol periods of the synchronization signal block based on determining that the synchronization signal block is associated with the remaining minimum system information dedicated to the first type of UE. In some cases, the first type of UE is a type of low-layer UE. In some cases, the first type of UE is a general UE.

[0161] The PBCH manager 825 may decode the physical broadcast channel signal of the synchronization signal block based on determining that the remaining minimum system information is dedicated to the first type of UE.

[0162] The CORESET manager 830 may decode a control resource set dedicated to the first type of UE based on the synchronization signal block and based on determining that the remaining minimum system information is dedicated to the first type of UE, wherein the control resource set dedicated to the first type of UE schedules a downlink shared channel carrying the remaining minimum system information, and wherein decoding the remaining minimum system information is further based on decoding a physical broadcast channel signal and the control resource set dedicated to the first type of UE. In some cases, the control resource set dedicated to the first type of UE comprises a type 0 control resource set (CORESET0).

[0163] The decoder controller 835 may terminate decoding of the synchronization signal block before the physical broadcast channel signal of the synchronization signal block is decoded based on determining that the remaining minimum system information is common. In some examples, the decoder controller 835 may terminate decoding of the second synchronization signal block before the UE decodes the physical broadcast channel signal of the second synchronization signal block based on detecting that the system information indication is absent.

[0164] The cell selection component 840 can identify that the synchronization signal block is a cell-defining synchronization signal block specific to the first type of UE based on the system information indication indicating that the synchronization signal block is associated with the remaining minimum system information specific to the first type of UE. In some examples, the cell selection component 840 can perform cell selection or reselection associated with the first type of UE based on the cell-defining synchronization signal block being specific to the first type of UE. In some cases, the cell-defining synchronization signal block specific to the first type of UE includes the same identifier as the universal cell-defining synchronization signal block.

[0165] Figure 9 A diagram of a system 900 including a device 905 supporting early indication of new radio lightweight dedicated system information according to aspects of the present disclosure is shown. The device 905 can be an example of or include components of the device 605, device 705, or UE 115 as described herein. The device 905 may include components for two-way voice and data communications, including components for sending and receiving communications, including a communication manager 910, an I / O controller 915, a transceiver 920, an antenna 925, a memory 930, and a processor 940. These components can communicate electronically via one or more buses (e.g., bus 945).

[0166] The communication manager 910 can receive a primary synchronization signal on a first subcarrier set and a system information indication on a second subcarrier set in a first symbol period of a synchronization signal block, determine that the synchronization signal block is associated with the remaining minimum system information dedicated to the first type of UE in response to receiving the system information indication, and decode the remaining minimum system information based on a physical broadcast channel signal in a second one or more symbol periods of the synchronization signal block based on the determination that the synchronization signal block is associated with the remaining minimum system information dedicated to the first type of UE.

[0167] I / O controller 915 can manage input and output signals for device 905. I / O controller 915 can also manage peripheral devices that are not integrated into device 905. In some cases, I / O controller 915 can represent a physical connection or port to an external peripheral device. In some cases, I / O controller 915 can utilize an operating system, such as MS- MS- or another known operating system. In other cases, I / O controller 915 may represent or interact with a modem, keyboard, mouse, touch screen, or similar device. In some cases, I / O controller 915 may be implemented as part of a processor. In some cases, a user may interact with device 905 via I / O controller 915 or via hardware components controlled by I / O controller 915.

[0168] As described above, the transceiver 920 can communicate bidirectionally via one or more antennas, wired or wireless links. For example, the transceiver 920 can represent a wireless transceiver and can communicate bidirectionally with another wireless transceiver. The transceiver 920 can also include a modem to modulate packets and provide the modulated packets to the antenna for transmission and demodulate packets received from the antenna.

[0169] In some cases, a wireless device may include a single antenna 925. However, in some cases, the device may have more than one antenna 925, which may be capable of concurrently sending or receiving multiple wireless transmissions.

[0170] The memory 930 may include RAM and ROM. The memory 930 may store computer-readable, computer-executable code 935 including instructions that, when executed, cause the processor to perform the various functions described herein. In some cases, the memory 930 may contain a basic input / output system (BIOS), which may control basic hardware or software operations, such as interaction with peripheral components or devices.

[0171] The processor 940 may include an intelligent hardware device (e.g., a general-purpose processor, a DSP, a CPU, a microcontroller, an ASIC, an FPGA, a programmable logic device, a discrete gate or transistor logic component, a discrete hardware component, or any combination thereof). In some cases, the processor 940 may be configured to operate a memory array using a memory controller. In other cases, the memory controller may be integrated into the processor 940. The processor 940 may be configured to execute computer-readable instructions stored in a memory (e.g., the memory 930) to cause the device 905 to perform various functions (e.g., functions or tasks that support early indication of new radio lightweight dedicated system information).

[0172] The code 935 may include instructions for implementing various aspects of the present disclosure, including instructions for supporting wireless communications. The code 935 may be stored in a non-transitory computer-readable medium (such as system memory or other types of memory). In some cases, the code 935 may not be directly executed by the processor 940, but may cause a computer (e.g., when compiled and executed) to perform the functions described herein.

[0173] Figure 10 A block diagram 1000 illustrates a device 1005 that supports early indication of new radio lightweight dedicated system information according to aspects of the present disclosure.
