Automatic Adaptation of Data Subcarrier Spacing Parameter Design Based on Synchronous Signal Block Transmission

Abstract

The subcarrier spacing (SCS) for data may be adapted or dynamically configured based on the presence or existence of a synchronization signal block (SSB) transmission. For example, during an SSB transmission, the SCS for data may be automatically switched from a default data SCS to a second SCS (e.g., the SCS for the SSB) to allow frequency division multiplexing (FDM) of data and SSB, wherein the data and SSB are designed using the same parameters. Thus, a communication device (e.g., a base station and user equipment (UE)) may identify a certain location or configuration of an SSB, and may determine a second subcarrier spacing (e.g., a subcarrier spacing associated with the SSB) so that the SCS for data may be adapted to the second subcarrier spacing during the SSB and the FDM of the data. The SSB and data may thus be transmitted or received concurrently using the second SCS.

[0003] Public domain

[0004] The present disclosure relates, for example, to wireless communication systems including automatic adaptation of data subcarrier spacing (SCS) based on synchronization signal block (SSB) transmissions. Background Art

[0005] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, etc. These systems may be able 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 that may be referred to as new radio (NR) systems. These systems may use various technologies, such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include several base stations or network access nodes, each of which simultaneously supports the communication of multiple communication devices, which may be referred to as user equipment (UE).

[0006] A base station may communicate with one or more other base stations and one or more UEs. In some examples of wireless communication systems, a base station and a UE may use one or more synchronization signal blocks (SSBs) to synchronize communications, establish connections, or both.

[0007] Overview

[0008] The described technology relates to improved methods, systems, devices and apparatuses that support automatic adaptation of data subcarrier spacing (SCS) based on synchronization signal block (SSB) transmission. For example, the described technology allows the SCS for data to be adapted or dynamically configured based on the occurrence or existence of SSB transmission. For example, during SSB transmission, the SCS of the data can be automatically switched from a default SCS (e.g., a default data SCS) to a second SCS (e.g., the SCS of the SSB) to provide improved frequency division multiplexing (FDM) of the data and the SSB (e.g., to allow the data and the FDM of the SSB to be designed using the same parameters). Thus, a communication device (e.g., a base station and a user equipment (UE)) can identify a certain position or configuration of the SSB, and can determine a second SCS (e.g., an SCS associated with the SSB) so that the SCS of the data can be adapted to the second SCS during the SSB and the FDM of the data. The SSB and data can thus be transmitted or received simultaneously using the second SCS.

[0098] Detailed Description

[0099] In some wireless communication systems, a base station and a user equipment (UE) may use one or more synchronization signal blocks (SSBs) to synchronize communications, or to establish a connection, or both. For example, a base station may transmit an SSB to a UE. The SSB may include one or more primary synchronization signals (PSSs) and one or more secondary synchronization signals (SSSs). The UE may use the PSS and SSS to synchronize with the base station. In some cases, the physical broadcast channel (PBCH) of the SSB may include a master information block (MIB). The MIB may include basic information that allows the UE to establish a connection with the base station. The base station may use one or more transmit beams to send SSB transmissions in a fixed, repetitive pattern based on establishing a connection with the UE, so that the SSB reception performance is stable and consistent for the UE (and each other UE served by the base station). For example, a base station may transmit an SSB during a set of time intervals (e.g., SSB positions or SSB opportunities) within a time period (e.g., an SSB period).

[0100] In some cases, a UE may be allocated a bandwidth portion (BWP) (e.g., the UE may be configured with an active BWP) to communicate with a serving base station. A BWP may be a set of contiguous physical resource blocks (PRBs) on a given wireless communication carrier. In some cases, each BWP may be associated with a parameter design, wherein the subcarrier spacing (SCS), symbol duration, and cyclic prefix length for the BWP are based on the parameter design. The PRB may be selected from a subset of contiguous common resource blocks that are allocated or assigned to the served UE by the base station. The UE may have an active BWP for uplink transmission and an active BWP for downlink communication. For example, the UE may transmit and receive within the frequency range of the active BWP, and the UE may not be configured to transmit or expect to receive outside the active BWP for uplink and downlink, respectively. In some cases, the base station that configures the BWP for the UE may indicate the start of the BWP (e.g., in frequency) based on an offset from a common reference point in the carrier. In some cases, the common reference point may correspond to a reference resource block, the start, end, or midpoint of a carrier, and the like.

[0101] For some communication systems (e.g., such as new radio (NR) systems, FR2x systems, FR4 systems, etc.), a wider bandwidth can be utilized so that the SCS for data and SSB can be amplified. However, the SCS of different types of transmissions cannot be amplified equally. For example, the SCS of data can be amplified (e.g., to 960kHz, 1.92MHz, or 3.84MHz) to enable the data to cover a wider bandwidth, while the SCS of the synchronization signal block (SSB) can be amplified relatively less relative to the data (e.g., to 120kHz, 240kHz, 480kHz, or 960kHz) to reduce or maintain a relatively low search complexity. In a situation where the wireless communication system employs frequency division multiplexing (FDM) between SSB and data, generating a mixed parameter design waveform (e.g., where the SCS of the data is amplified differently from the SCS of the SSB) may be inefficient. For example, time domain summation of two Inverse Fast Fourier Transform (IFFT) outputs of FDM for SSB and data (eg, each with different parameter designs) may result in increased complexity at a receiving device or a transmitting device.

[0102] According to the techniques described herein, the SCS of the data may be adapted or dynamically configured based on the presence or existence of the SSB. For example, during SSB transmission (e.g., during an SSB position or SSB opportunity), the SCS of the data may be automatically switched from a certain default SCS (e.g., a certain default data SCS) to a second SCS (e.g., the SCS of the SSB) to provide improved FDM of the data and the SSB (e.g., to allow the data and the FDM of the SSB to be designed using the same parameters). Thus, a communication device (e.g., a base station, a UE, etc.) may identify a certain position or configuration of the SSB (e.g., such as one or more SSB positions or SSB opportunities), and may determine a second SCS (e.g., an SCS associated with the SSB) so that the SCS of the data may be adapted to the second SCS during the SSB and the FDM of the data. The SSB and the data may thereby be transmitted or received simultaneously using the second SCS (e.g., via efficient FDM techniques).

[0103] In some cases, the SCS of the data may vary (e.g., be dynamically configured) within a BWP. For example, a BWP may be associated with a data parameter design and an SSB parameter design, wherein the SCS, symbol duration, and cyclic prefix length used for the BWP are based on the data parameter design (e.g., in portions or durations of the BWP without an SSB) and the SSB parameter design (e.g., in portions or durations of the BWP that include the SSB). In such cases, when an SSB is transmitted (e.g., within an active BWP), the SCS of the SSB may be used for the SCS of the data (e.g., so that the SSB and FDM of the data use the SCS of the SSB). Otherwise, a default SCS for the data may be used if the data is transmitted (e.g., within an active BWP).

[0104] In other examples, the BWP may be switched automatically (e.g., without DCI indication) within and outside of an SSB burst. For example, a wireless communication system may employ separate BWPs for data and FDM for SSB and data, wherein a first BWP may be associated with an SSB parameter design (e.g., wherein an SSB SCS, SSB symbol duration, and SSB cyclic prefix length for the BWP are based on the SSB parameter design) and a second BWP may be associated with a data parameter design (e.g., wherein a data SCS, data symbol duration, and data cyclic prefix length for the BWP are based on the data parameter design). In such examples, outside of an SSB burst, a second BWP (e.g., active) may be used with a default SCS for data. Within an SSB burst, the second BWP may be switched to a first BWP in which the SCS for data is the same as the SCS for the SSB.

[0105] Various aspects of the present disclosure are initially described in the context of a wireless communication system. Example SCS configurations, SCS adaptation diagrams, UE feedback diagrams, BWP configurations, and process flows are then described that illustrate one or more aspects of the techniques discussed herein. Various aspects of the present disclosure are further illustrated and described by and with reference to apparatus diagrams, system diagrams, and flow diagrams related to automatic adaptation of data SCS parameter design based on SSB transmission.

[0106] Figure 1An example of a wireless communication system supporting automatic adaptation of data SCS parameter design based on SSB transmission according to various aspects of the present disclosure is shown. The wireless communication system 100 includes a base station 105, a UE 115, and a core network 130. In some examples, the wireless communication system 100 can be a long term evolution (LTE) network, an advanced LTE (LTE-A) network, an LTE-A Pro network, or an NR network. In some cases, the wireless communication system 100 can support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low latency communication, or communication with low-cost and low-complexity devices.

[0107] The base station 105 may communicate wirelessly with the UE 115 via one or more base station antennas. The base station 105 described herein may include or may be referred to by those skilled in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a Home Node B, a Home Evolved Node B, or some other suitable terminology. The wireless communication system 100 may include different types of base stations 105 (e.g., macro cell base stations or small cell base stations). The UE 115 described herein may be able to communicate with various types of base stations 105 and network equipment (including macro eNBs, small cell eNBs, gNBs, relay base stations, etc.).

[0108] Each base station 105 may be associated with a geographic coverage area 110, supporting communications with various UEs 115 in the particular geographic coverage area 110. Each base station 105 may provide communication coverage for the corresponding geographic coverage area 110 via a communication link 125, and the communication link 125 between the base station 105 and the UE 115 may utilize one or more carriers. The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. Downlink transmissions may also be referred to as forward link transmissions, and uplink transmissions may also be referred to as reverse link transmissions.

[0109] The geographic coverage area 110 of the base station 105 may be divided into sectors that constitute a portion of the geographic coverage area 110, and each sector may be associated with a cellular cell. For example, each base station 105 may provide communication coverage for a macrocellular cell, a small cellular cell, a hotspot, or other types of cellular cells, or various combinations thereof. In some examples, the base station 105 may be mobile and may therefore provide communication coverage for a geographic coverage area 110 that is also mobile. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, so that the geographic coverage areas 110 associated with different technologies may overlap and may be supported by the same base station 105 or different base stations 105. The wireless communication system 100 may include, for example, a heterogeneous LTE / LTE-A / LTE-A Pro or NR network, in which different types of base stations 105 provide coverage for various geographic coverage areas 110.

[0110] The term "cell" refers to a logical communication entity used to communicate with base station 105 (e.g., on a carrier), and may be associated with an identifier to distinguish adjacent cells operating via the same or different carriers (e.g., physical cell identifier (PCID), virtual cell identifier (VCID)). In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types that may provide access to different types of devices (e.g., machine type communication (MTC), narrowband Internet of Things (NB-IoT), enhanced mobile broadband (eMBB), or others). In some cases, the term "cell" may refer to a portion (e.g., a sector) of a geographic coverage area 110 on which the logical entity operates.

[0111] Each UE 115 can be dispersed throughout the wireless communication system 100, and each UE 115 can be stationary or mobile. UE 115 can also be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable term, wherein "device" can also be referred to as a unit, a station, a terminal, or a client. UE 115 can also be 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 can also refer to a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or an MTC device, etc., which can be implemented in various items (such as electrical appliances, vehicles, meters, etc.).

[0112] 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 the information to a central server or application, which may utilize the information or present the information to a person interacting with the program or application. Some UEs 115 may be designed to collect information or implement automated behavior of machines. Examples of applications for MTC devices include: smart metering, inventory monitoring, water level monitoring, equipment monitoring, health care monitoring, field survival monitoring, weather and geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial charging.

[0113] Some UEs 115 may be configured to employ a reduced power consumption mode of operation, 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 with a reduced peak rate. Other power saving techniques for UE 115 include entering a power saving "deep sleep" mode when not engaged in active communications, or operating over a limited bandwidth (e.g., in accordance with narrowband communications). In some cases, UE 115 may be designed to support critical functions (e.g., mission critical functions), and the wireless communication system 100 may be configured to provide ultra-reliable communications for these functions.

[0114] In some cases, UE 115 may also be able to communicate directly with other UE 115 (e.g., using a peer-to-peer (P2P) or device-to-device (D2D) protocol). One or more UEs in a group of UEs 115 utilizing D2D communication may be within the geographic coverage area 110 of the base station 105. Other UEs 115 in the group may be outside the geographic coverage area 110 of the base station 105, or may not be able to receive transmissions from the base station 105 for other reasons. In some cases, each 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 cases, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between each UE 115 without involving the base station 105.

[0115] The base stations 105 may communicate with the core network 130 and with each other. For example, the base stations 105 may interface with the core network 130 via a backhaul link 132 (e.g., via S1, N2, N3, or other interfaces). The base stations 105 may communicate with each other over a backhaul link 134 (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).

[0116] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC), which may include at least one mobility management entity (MME), at least one serving gateway (S-GW), and at least one packet data network (PDN) gateway (P-GW). The MME may manage non-access layer (e.g., control plane) functions such as mobility, authentication, and bearer management of UEs 115 served by base stations 105 associated with the EPC. User IP packets may be delivered through the S-GW, which itself may be connected to the P-GW. The P-GW may provide IP address allocation and other functions. The P-GW may be connected to network operator IP services. Operator IP services may include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or packet switched (PS) streaming services.

[0117] At least some network devices (such as base stations 105) may include subcomponents, such as access network entities, which may be examples of access node controllers (ANCs). Each access network entity may communicate with each UE 115 through a number of other access network transport entities, which may be referred to as radio heads, smart radio heads, or transmission / reception points (TRPs). In some examples, the various functions of each access network entity or base station 105 may be distributed across various network devices (e.g., radio heads and access network controllers) or merged into a single network device (e.g., base station 105).

[0118] The wireless communication system 100 may operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). For example, the 300 MHz to 3 GHz region is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from about 1 decimeter to 1 meter long. UHF waves may be blocked or redirected by buildings and environmental features. However, these waves may penetrate various structures sufficiently for macro cells to provide services to UEs 115 located indoors. Transmission of UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 km) compared to transmission using lower frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0119] The wireless communication system 100 may also operate in the Super High Frequency (SHF) region using frequency bands from 3 GHz to 30 GHz, also known as centimeter bands. The SHF region includes frequency bands that may be opportunistically used by devices that may be able to tolerate interference from other users, such as the 5 GHz Industrial, Scientific, and Medical (ISM) band.

[0120] The wireless communication system 100 may also operate in the extremely high frequency (EHF) division of the spectrum (e.g., from 30 GHz to 300 GHz), which is also referred to 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 antenna of the corresponding device may be even smaller and more closely spaced than the UHF antenna. In some cases, this may facilitate the use of antenna arrays within the UE 115. However, the propagation of EHF transmissions may be subject to even greater atmospheric attenuation and shorter range than SHF or UHF transmissions. The technology disclosed herein may be adopted across transmissions using one or more different frequency divisions, and the use of frequency bands specified across these frequency divisions may differ by country or regulatory agency.

[0121] In some cases, the wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may employ license assisted access (LAA), LTE unlicensed radio access technology, or NR technology in an unlicensed band (such as a 5 GHz ISM band). When operating in an unlicensed radio frequency spectrum band, wireless devices (such as base stations 105 and UE 115) may employ a listen-before-talk (LBT) procedure to ensure that the frequency channel is clear before transmitting data. In some cases, operations in unlicensed bands may be based on carrier aggregation configurations (e.g., LAA) in coordination with component carriers (CCs) operating in licensed bands. Operations in unlicensed spectrum may include downlink transmissions, uplink transmissions, peer-to-peer transmissions, or a combination of these. Duplexing in unlicensed spectrum may be based on frequency division duplexing (FDD), time division duplexing (TDD), or a combination of the two.

[0122] In some examples, the base station 105 or the UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. For example, the wireless communication system 100 may use a transmission scheme between a transmitting device (e.g., the base station 105) and a receiving device (e.g., the UE 115), wherein the transmitting device is equipped with multiple antennas and the receiving device is equipped with one or more antennas. MIMO communication may employ multipath signal propagation to increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers, which may be referred to as spatial multiplexing. For example, the transmitting device may transmit multiple signals via different antennas or different antenna combinations. Similarly, the receiving device may receive multiple signals via different antennas or different antenna combinations. Each of these multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams. Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO), in which multiple spatial layers are transmitted to the same receiving device, and multi-user MIMO (MU-MIMO), in which multiple spatial layers are transmitted to multiple devices.

[0123] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a base station 105 or a UE 115) to shape or direct an antenna beam (e.g., a transmit beam or a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals communicated via antenna elements of an antenna array so that some signals propagating at certain orientations relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements may include the transmitting device or the receiving device applying amplitude and phase shifts to signals carried via each antenna element associated with the device. Adjustments associated with each antenna element may be defined by a set of beamforming weights associated with an orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0124] In one example, the base station 105 may use multiple antennas or antenna arrays to perform beamforming operations for directional communication with the UE 115. For example, some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by the base station 105 in different directions, which may include a signal being transmitted according to different beamforming weight sets associated with different transmission directions. The transmissions in different beam directions may be used (e.g., by the base station 105 or a receiving device, such as the UE 115) to identify the beam direction used by the base station 105 for subsequent transmission or reception.

[0125] Some signals, such as data signals associated with a receiving device, may be transmitted by base station 105 in a single beam direction (e.g., a direction associated with a receiving device, such as UE 115). In some examples, a beam direction associated with transmissions along a single beam direction may be determined based at least in part on signals transmitted in different beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions, and UE 115 may report to base station 105 an indication of the signals received by it with the highest signal quality or other acceptable signal quality. Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may use similar techniques for transmitting signals multiple times in different directions (e.g., for identifying a beam direction used by UE 115 for subsequent transmission or reception) or for transmitting signals in a single direction (e.g., for transmitting data to a receiving device).

[0126] A receiving device (e.g., UE 115, which may be an example of a mmW receiving device) may try multiple receive beams when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105. For example, the receiving device may try multiple receive directions by receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, or processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as "listening" according to different receive beams or receive directions. In some examples, the receiving device may use a single receive beam to receive along a single beam direction (e.g., when receiving a data signal). A single receive beam may be aligned in a beam direction determined based at least in part on listening according to different receive beam directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio, or other acceptable signal quality based at least in part on listening according to multiple beam directions).

[0127] In some cases, the antennas of a base station 105 or a UE 115 may be located within one or more antenna arrays that may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some cases, the antennas or antenna arrays associated with a base station 105 may be located at different geographic locations. A base station 105 may have an antenna array having several rows and columns of antenna ports that the base station 105 may use to support beamforming for communications with a UE 115. Similarly, a UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations.

[0128] In some cases, the wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, the communication of the bearer or packet data convergence protocol (PDCP) layer may be IP-based. The radio link control (RLC) layer may perform packet segmentation and reassembly to communicate on a logical channel. The media access control (MAC) layer may perform priority handling and multiplex logical channels into transport channels. The MAC layer may also use a hybrid automatic repeat request (HARQ) to provide retransmission of the MAC layer, thereby improving link efficiency. In the control plane, the radio resource control (RRC) protocol layer may provide the establishment, configuration and maintenance of an RRC connection for a radio bearer that supports user plane data between UE115 and base station 105 or core network 130. At the physical layer, transport channels may be mapped to physical channels.

[0129] In some cases, UE 115 and base station 105 may support retransmission of data to increase the likelihood that the data is successfully received. HARQ feedback is a technique that increases the likelihood of correctly receiving data on communication link 125. HARQ may include a combination of error detection (e.g., using cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ can improve the throughput of the MAC layer in poor radio conditions (e.g., signal-to-noise ratio conditions). In some cases, a wireless device may support simultaneous slot HARQ feedback, where the device may provide HARQ feedback in a specific time slot for data received in a previous symbol in the time slot. In other cases, the device may provide HARQ feedback in a subsequent time slot or according to some other time interval.

[0130] The time interval in LTE or NR can be represented by a basic time unit (which may refer to a sampling period T, for example). s =1 / 30,720,000 seconds). The time intervals of the communication resources may be organized according to radio frames each having a duration of 10 milliseconds (ms), where the frame period may be expressed as T f =307,200T s. A radio frame may be identified by a system frame number (SFN) ranging from 0 to 1023. Each frame may include 10 subframes numbered from 0 to 9, and each subframe may have a duration of 1 ms. A subframe may be further divided into 2 slots, each slot having a duration of 0.5 ms, and each slot may contain 6 or 7 modulation symbol periods (e.g., depending on the length of a cyclic prefix prepended to each symbol period). Excluding the cyclic prefix, each symbol period may contain 2048 sampling periods. In some cases, a subframe may be the minimum scheduling unit of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In other cases, the minimum scheduling unit of the wireless communication system 100 may be shorter than a subframe or may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI) or in a selected CC using sTTI).

[0131] In some wireless communication systems, a time slot may be further divided into a plurality of mini-slots containing one or more symbols. In some instances, a symbol of a mini-slot or a mini-slot may be the minimum scheduling unit. For example, each symbol may vary in duration depending on the subcarrier spacing or the operating frequency band. Further, some wireless communication systems may implement time slot aggregation, wherein a plurality of time slots or mini-slots are aggregated together and used for communication between UE 115 and base station 105.

[0132] The term "carrier" refers to a set of radio frequency spectrum resources having a defined physical layer structure for supporting communications on the communication link 125. For example, a carrier of the communication link 125 may include a portion of a radio frequency spectrum band that operates according to a physical layer channel for a given radio access technology. Each physical layer channel may carry user data, control information, or other signaling. A carrier may be associated with a predefined frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be located according to a channel grid for discovery by a UE 115. A carrier may be downlink or uplink (e.g., in FDD mode), or configured to carry downlink communications and uplink communications (e.g., in TDD mode). In some examples, a signal waveform transmitted on a carrier may include multiple subcarriers (e.g., using a multi-carrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)).

[0133] For different radio access technologies (e.g., LTE, LTE-A, LTE-A Pro, NR), the organizational structure of the carrier can be different. For example, the communication on the carrier can be organized according to TTIs or time slots, each of which can include user data and control information or signaling to support decoding of the user data. The carrier can also include dedicated acquisition signaling (e.g., synchronization signals or system information, etc.) and control signaling to coordinate the operation of the carrier. In some examples (e.g., in a carrier aggregation configuration), the carrier may also have acquisition signaling or control signaling to coordinate the operation of other carriers.

[0134] 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 a time division multiplexing (TDM) technique, an FDM technique, or a hybrid TDM-FDM technique. In some examples, control information transmitted in a physical control channel may be distributed in a cascaded manner between different control regions (e.g., between a common control region or a common search space and one or more UE-specific control regions or UE-specific search spaces).

[0135] A carrier may be associated with a bandwidth of a radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as a "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of several predetermined bandwidths (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz) of a carrier of a radio access technology. In some examples, each UE 115 may be configured to operate on part or all of the carrier bandwidth. In other examples, some UEs 115 may be configured for operation using a narrowband protocol type associated with a predefined portion or range (e.g., a set of subcarriers or RBs) within a carrier (e.g., an "in-band" deployment of a narrowband protocol type).

[0136] In a system using MCM technology, a resource element may include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and the subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme). Thus, the more resource elements received by UE 115 and the higher the order of the modulation scheme, the higher the data rate of UE 115 can be. In a MIMO system, wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and space resources (e.g., space layers), and the use of multiple space layers may further increase the data rate of communication with UE 115.

[0137] A device (e.g., base station 105 or UE 115) of wireless communication system 100 may have a hardware configuration that supports communication over a carrier bandwidth, or may be configurable to support communication over one of a set of carrier bandwidths. In some examples, wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with more than one different carrier bandwidth.

[0138] The wireless communication system 100 may support communication with the UE 115 on multiple cells or carriers, a feature that may be referred to as carrier aggregation or multi-carrier operation. The UE 115 may be configured with multiple downlink CCs and one or more uplink CCs according to a carrier aggregation configuration. Carrier aggregation may be used with both FDD CCs and TDD CCs.

[0139] In some cases, the wireless communication system 100 may utilize an enhanced CC (eCC). An eCC may be characterized by one or more features including a wider carrier or frequency channel bandwidth, a shorter symbol duration, a shorter TTI duration, or a modified control channel configuration. In some cases, an eCC may be associated with a carrier aggregation configuration or a dual connectivity configuration (e.g., when multiple serving cells have suboptimal or non-ideal backhaul links). An eCC may also be configured to be used in an unlicensed spectrum or a shared spectrum (e.g., where more than one operator is allowed to use the spectrum). An eCC characterized by a wide carrier bandwidth may include one or more segments that may be utilized by a UE 115 that is not capable of monitoring the entire carrier bandwidth or is otherwise configured to use a limited carrier bandwidth (e.g., to save power).

[0140] In some cases, an eCC may utilize a different symbol duration than other CCs, which may include using a reduced symbol duration compared to the symbol duration of other CCs. A shorter symbol duration may be associated with an increased spacing between adjacent subcarriers. A device utilizing an eCC (such as a UE 115 or a base station 105) may transmit a wideband signal (e.g., according to a frequency channel or carrier bandwidth of 20, 40, 60, 80 MHz, etc.) with a reduced symbol duration (e.g., 16.67 microseconds). A TTI in an eCC may include one or more symbol periods. In some cases, the TTI duration (i.e., the number of symbol periods in a TTI) may be variable.

[0141] The wireless communication system 100 may be an NR system that may utilize any combination of licensed, shared, and unlicensed spectrum bands, etc. The flexibility of eCC symbol duration and subcarrier spacing may allow eCC to be used across multiple spectrums. In some examples, NR shared spectrum may improve spectrum utilization and spectrum efficiency, particularly through dynamic vertical (e.g., across frequency domain) and horizontal (e.g., across time domain) sharing of resources.

[0142] The wireless communication system 100 may support adapting or dynamically configuring the SCS of data based on the presence or existence of an SSB. For example, during SSB transmission (e.g., during an SSB position or SSB opportunity), the SCS of the data may be automatically switched from a default SCS (e.g., a default data SCS) to a second SCS (e.g., the SCS of the SSB) to provide improved FDM of the data and the SSB (e.g., to allow the data and the FDM of the SSB to be designed using the same parameters). Thus, a communication device (e.g., a base station 105, a UE 115, etc.) may identify a certain position or configuration of the SSB (e.g., such as one or more SSB positions or SSB opportunities), and may determine a second SCS (e.g., an SCS associated with the SSB) so that the SCS of the data may be adapted to the second SCS during the SSB and the FDM of the data. The SSB and the data may thereby be transmitted or received contemporaneously using the second SCS (e.g., via efficient FDM techniques).

[0143] For example, UE 115 may receive first data information transmitted using a first SCS (e.g., transmitted by base station 105). UE 115 may receive DCI including an indication of a synchronization signal (e.g., SSB) in a first BWP on a physical downlink control channel (PDCCH), and UE 115 may determine a second SCS (e.g., an SCS of the SSB) based on the indication. Thus, UE 115 may concurrently receive the synchronization signal and the second data information transmitted by base station 105 using the determined second SCS.

[0144] In some examples, the SCS of the data can be varied (e.g., dynamically configured) within a BWP (e.g., within a first BWP). For example, the first BWP can be associated with both a data parameter design and an SSB parameter design, wherein the SCS, symbol duration, or cyclic prefix length used for the BWP is based on the data parameter design (e.g., in portions or durations of the BWP without an SSB, such as for receiving the first data information) and the SSB parameter design (e.g., in portions or durations of the BWP that include the SSB, such as for receiving the SSB and second data information). In some other examples, the BWP can switch automatically (e.g., without DCI indication) within and outside of an SSB burst. For example, the wireless communication system 100 can employ separate BWPs for data and for FDM of SSB and data. In such examples, the second BWP can be associated with a data parameter design (e.g., where the data SCS, data symbol duration, and data cyclic prefix length for the BWP are based on the data parameter design) and the first BWP can be associated with an SSB parameter design (e.g., where the SSB SCS, SSB symbol duration, and SSB cyclic prefix length for the BWP are based on the SSB parameter design). Thus, the second BWP can be used to receive the first data information and the first BWP can be used to receive the SSB and the second data information.

[0145] Figure 2 An example of a wireless communication system that supports automatic adaptation of data SCS parameter design based on SSB transmission according to various 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 may include a base station 105 and a UE 115, which may be, for example, Figure 1 Shown and referenced Figure 1 2 and 3. An example of a base station 105 and a UE 115 is depicted. The base station 105 may communicate with the UE 115 (e.g., send a transmission 210 to the UE 115) via a communication link 205. Figure 2 In the example of , transmission 210-a may include FDM of data 215 and SSB 220 and transmission 210-b may include data 215. Techniques described herein may provide for adaptation of the SCS of data 215 (across transmission 210-a and transmission 210-b).

[0146] Some wireless communication systems (e.g., wireless communication system 200, which may include a FR2x system or a FR4 system) may utilize a wider bandwidth than certain other wireless communication systems, which may result in a scaling of the SCS due to the wider available bandwidth in such wireless communication systems. However, the SCSs of different types of transmissions may not be scaled up equally. For example, the SCS of data (e.g., the SCS of data 215) may be scaled up to enable the data to cover a wider bandwidth, while the SCS of SSB (e.g., the SCS of SSB 220) may be scaled up less relative to the scaling of the data SCS (e.g., to reduce search complexity). For example, data 215 may be associated with an SCS of 960 kHz, 1.92 MHz, or 3.84 MHz, while SSB 220 may be associated with an SCS of 120 kHz, 240 kHz, 480 kHz, or 960 kHz.

[0147] Generating a transmit waveform including two different SCSs (e.g., two different parameter designs) may be difficult due to the additional processing complexity of the base station 105 or the UE 115. For example, generating a hybrid parameter design transmit waveform may involve the time domain summation of two IFFT outputs, each with a different parameter design. Alternatively, transmissions with different SCSs may not be transmitted together (e.g., FDM cannot be used). However, this may result in increased transmission latency because a transmission with a first SCS (e.g., data 215 with a data SCS) may be delayed or stopped until a transmission with a second SCS (e.g., SSB 220 with an SSB SCS) is performed. This increased latency may result in degradation of system performance or user experience (e.g., in a scenario with downlink emergency traffic).

[0148] In some implementations of the present disclosure, the SCS of data 215 may be automatically adapted (e.g., dynamically configured) to match the SCS of SSB 220 when data 215 and SSB 220 are scheduled for concurrent transmission (e.g., FDM for data 215 and SSB 220 in transmission 210-a). For example, when data 215 and SSB 220 are transmitted concurrently (e.g., contemporaneously), the SCS of data 215 may be adapted to the SCS of SSB 220. This may enable efficient transmission of data 215 and SSB 220 (e.g., via transmission 210-a) when the SCS of data 215 and SSB 220 would otherwise be different in a default configuration (e.g., because transmission 210-a for FDM for data 215 and SSB 220 may be generated based on the same SCS for data 215 and SSB 220).

[0149] In some cases, the SCS of data 215 may be adapted (e.g., switched, configured, etc.) to match the SCS of SSB 220 during an SSB position or SSB timing within a BWP (e.g., within an active BWP for transmission 210-a and transmission 210-b). In such cases, the SCS of data 215 may be adapted to the SCS of SSB 220 during transmission of SSB 220 within the active BWP. For example, the SCS of data 215 may be adapted within the BWP based on the position or timing of SSB 220 (e.g., the SCS of data 215 may be adapted or configured to the SCS of SSB 220 during transmission 210-a). When SSB 220 is not transmitted (e.g., in transmission 210-b), the SCS of data 215 may remain unchanged (e.g., a default SCS of the data may be maintained according to the data parameter design of the active BWP). When SSB 220 is transmitted (eg, in transmission 210 - a ), the SCS of data 215 may be adapted to the SCS of SSB 220 according to the SSB parameter design of the active BWP during transmission 210 - a .

[0150] In some examples, the BWP may switch automatically (e.g., without DCI indication) within and outside of SSB positions or timings. For example, separate BWPs may be used for data 215 (e.g., for transmission 210-b) and for FDM of data 215 and SSB 220 (e.g., for transmission 210-a). For example, a first BWP may be associated with an SSB parameter design (e.g., associated with an SSB SCS) and a second BWP may be associated with a data parameter design (e.g., associated with a default data SCS), and thus the second BWP may be used when data 215 is transmitted (e.g., transmission 210-b may be associated with the second BWP) and the first BWP may be used when data 215 and SSB 220 are FDM (e.g., transmission 210-a may be associated with the first BWP). Thus, in transmission 210-b, when SSB 220 is not transmitted, the second BWP may be used to transmit the data at the default SCS of the data. In transmission 210 - a , when the SSB is transmitted, the second BWP may be switched to the first BWP so that data 215 and SSB 220 may be transmitted over the same SCS (eg, an SCS corresponding to SSB 220 ).

[0151] The SCS of data 215 may be switched at several different locations in the time domain. That is, the described techniques provide for various SCS configuration boundaries (e.g., SCS switching boundaries, SCS adaptation triggers, etc.) for adapting the SCS based on the presence or completion of a transmission of SSB 220. In some cases, the SCS of data 215 may be adapted to match the SCS of SSB 220 at an SSB symbol boundary associated with SSB 220 (symbol-level switching). For example, data 215 may be transmitted with a default SCS until the first symbol of a transmission containing SSB 220 (e.g., the first symbol of an SSB burst according to the parameter design of SSB 220). In this case, the data slot boundaries and SSB symbol boundaries may not be aligned at the switching point (e.g., as described herein, for example with reference to Figure 4 described in more detail).

[0152] In some cases, the SCS of data 215 may be adapted to match the SCS of SSB 220 at an SSB slot boundary (slot-level switching) associated with SSB 220. For example, data 215 may be transmitted via a first SCS until the first slot containing an SSB 220 transmission. In this case, the data slot boundary and the SSB slot boundary may be aligned at the switching point. In some cases, the SCS of data 215 may be adapted to match the SCS of SSB 220 at an SSB burst boundary (SSB burst-level switching) associated with SSB 220. For example, data 215 may be transmitted via a first SCS until the first subframe of the SSB burst. In this case, the data slot boundary and the SSB slot boundary may be aligned at the switching point.

[0153] In some cases, a DCI indication (e.g., a K0 / K1 indication) may indicate the location of downlink data (e.g., data 215) and where the UE may transmit an ACK / negative acknowledgement (NACK). In other words, the DCI may include a K0 / K1 indication for scheduling downlink data (e.g., on a physical downlink shared channel (PDSCH)) and a corresponding uplink feedback opportunity, respectively. For example, K0 may indicate the number of time slots until a time slot containing data 215 associated with the indication may be received, and K1 may indicate the number of time slots between the time slot containing the data 215 and when the UE may transmit an ACK / NACK associated with the data 215.

[0154] In some cases, during an SSB transmission (e.g., during transmission 210-a), K0 / K1 may be defined in a first slot pattern (e.g., a virtual slot pattern), which may be defined relative to the SCS of data 215. In such cases, for example, a virtual slot duration may be defined during transmission 210-a and may be the same as a slot duration of data 215 outside of an SSB transmission (e.g., during transmission 210-b). In some cases, the SCS of SSB 220 may be defined as M and the SCS of data 215 may be defined as N. In these examples, the virtual slot duration during transmission 210-a may be defined as:

[0155] N / M*{slot duration relative to the SCS of the data}

[0156] In some other cases, during transmission 210-a, K0 / K1 may be defined according to a second slot pattern (e.g., an actual slot pattern), which may be defined relative to the SCS of SSB 220. In these cases, for example, the actual slot duration during transmission 210-a may be different from the slot duration of data 215 in transmission 210-b such that the slot duration varies.

[0157] In some cases, a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook may be designed based on the K1 indication. For example, K1 may be defined based on a virtual time slot or an actual time slot, and the HARQ-ACK codebook may be designed based on the definition of K1. For example, when K1 is defined based on a virtual time slot (e.g., a time slot defined based on the default SCS of data 215), the codebook may include information (e.g., number of bits) indicating the ACK / NACK for each virtual time slot during transmission 210-a. In some cases, the ACK / NACK for the virtual time slot may be set to NACK in its entirety. In other cases, the ACK / NACK for the virtual time slot may be set to ACK or NACK in its entirety according to the indication of the first virtual time slot during transmission 210-a. For example, the codebook entry for each virtual time slot during transmission 210-a may be set equal to the entry for the first virtual time slot during transmission 210-a. In some cases, designing a codebook based on a virtual time slot may improve feedback reliability.

[0158] When K1 is defined based on an actual time slot (e.g., a time slot defined based on the SCS of SSB 220), the codebook may include information (e.g., a number of bits) about a single time slot during transmission 210-a (e.g., a single time slot corresponding to the duration of the transmission of SSB 220). For example, the codebook may carry a single entry for a single time slot during transmission 210-a, rather than carrying entries for several virtual time slots during transmission 210-a. In some cases, this may enable the UE to omit a portion of the codebook (e.g., to reduce feedback overhead).

[0159] In some cases, the SCS of the data 215 may be adapted to match the SCS of the SSB 220 via a BWP switch (e.g., where a second BWP is active for transmission 210-b and a first BWP is active for transmission 210-a). For example, the active BWP may be switched from a default BWP to a first BWP, during which the data 215 and the SSB 220 may be transmitted, and then may be switched back to the default BWP after the transmission of the SSB 220. In some cases, a switchback point may be defined. For example, in some cases, the switchback point may be defined as a time interval ΔT that occurs after the transmission 210-a is completed. For example, the transmission 210-a may be completed at T1, and the switchback point may occur at T1+ΔT. In some cases, the time interval ΔT may enable the base station 105 to address the ACK / NACK before making the switch. Additionally or alternatively, the configuration of the BWP during the transmission 210-a may be semi-statically indicated (e.g., via an RRC or MAC control element (MAC-CE)). In some cases, the indication may include a time interval ΔT, a bandwidth of a bandwidth portion, etc. For example, the bandwidth of the BWP used during transmission 210-a may be the same as or different from the bandwidth of a default BWP used for transmission 210-b. In some other cases, the switchback point may be indicated dynamically (e.g., via DCI). For example, the base station 105 may determine the switchback point based on the HARQ process in the BWP used for transmission 210-a and indicate the switchback point via DCI.

[0160] Figure 3A An example SCS configuration supporting automatic adaptation of data SCS parameter design based on SSB transmission according to aspects of the present disclosure is illustrated. In some examples, SCS configuration 300 and SCS configuration 301 can be implemented to implement aspects of wireless communication system 100 or wireless communication system 200.

[0161] The SCS configuration 300 may illustrate an example in which the SSB 310 and the data 315 are within an active BWP 320-a (e.g., within a first BWP). In some cases, the SSB 310 may be associated with a different SCS than the data 315-a. For example, the data 315-a may be associated with a first SCS (e.g., a default data SCS#1), while the SSB 310 may be associated with a second SCS (e.g., SCS#2). In these cases, the active BWP 320-a may be associated with a data parameter design (supporting SCS#1) and an SSB parameter design (supporting SCS#2) to support transmission of both the SSB 310 and the data 315 within the active BWP 320-a (e.g., wherein the data parameter design is employed when the SSB 310 is temporarily absent and the SSB parameter design is employed when the SSB 310 is temporarily present). In some cases, the data 315 and the SSB 310 cannot be transmitted together (e.g., may not be FDM). For example, data 315-a may be transmitted during a first time period and SSB 310 may be transmitted during a second time period after the first time period (when data 315-a is not transmitted). In the case where data 315 and SSB 310 are not FDM, the SCS of data 315 may not match the SCS of SSB 310 (e.g., because data 315 may not be transmitted via SSB 310).

[0162] The SCS configuration 301 may illustrate an example where the SSB 310 may be transmitted outside of the active BWP 320-a, while the data 315 may be transmitted within the active BWP 320-a. For example, the SSB 310 may not be expected to be within the active BWP 320-a. The SCS configuration 301 may be configured similarly to the SCS configuration 300 and may not transmit the data 315 and the SSB 310 concurrently (e.g., the data 315 and the SSB 310 may not be FDM). In situations where the SSB 310 may not be expected to be within the active BWP 320-a, the data 315 may still be transmitted during the SSB 310 position. In these situations, the SCS #1 of the data 315 may not fit into the SCS #2 of the SSB 310. In some examples, data 315 - a may not be configured with a data SCS, and the UE may switch to a different BWP to receive SSB 310 (eg, where the different BWP may be associated with an SCS corresponding to SSB 310 ).

[0163] Figure 3B Example SCS configurations supporting automatic adaptation of data SCS parameter design based on SSB transmissions according to aspects of the present disclosure are illustrated. In some examples, SCS configuration 302 and SCS configuration 303 may be implemented to implement aspects of wireless communication system 100 or wireless communication system 200.

[0164] The SCS configuration 302 may illustrate an example where the SSB 310 is within an active BWP 320-b. In these situations, according to implementations of the present disclosure, the SCS may be adapted during transmission of the data 315. For example, a first SCS (e.g., SCS #1) may be used for transmission of the data 315-a. During transmission of the SSB 310 within the active BWP 320-b (e.g., where the SSB 310 and the data 315-b are FDMed), the SCS may be adapted or configured such that a second SCS (e.g., SCS #2) may be used for transmission / reception of both the SSB 310 and the data 315-b. The active BWP 320-a can be associated with a data parameter design (supporting SCS#1) and an SSB parameter design (supporting SCS#2) to support transmission of both SSB 310 and data 315 within the active BWP 320-a (e.g., where the data parameter design is adopted when the SSB 310 is temporarily absent and the SSB parameter design is adopted when the data 315 and SSB 310 are FDMed).

[0165] In some cases, a communication device (e.g., a base station and a UE) may identify a location or configuration for an SSB 310. For example, one or more SSB locations or SSB opportunities for an SSB burst may be identified. An SCS configuration 302 may illustrate an example of an identified SSB configuration. The SCS configuration 302 may include a transmission of data 315 and an SSB 310 transmission within an active BWP 320-b. In a first time period before an SSB 310 opportunity, the data 315 may be transmitted via SCS #1 (e.g., a default data SCS). The transmission of data 315-a (data 315 in SCS #1) in the first time period may be transmission 210-b (e.g., a default data SCS). Figure 2 310-a (shown in FIG. 2 ). When SSB 310 is transmitted, the SCS of data 315-a (SCS #1) may be adapted to the SCS of SSB 310 (SCS #2). For example, both data 315-b (data 315 in SCS #2) and SSB 310 may be transmitted using the SCS of SSB 310. In some cases, transmitting both data 315-b and SSB 310 via SCS #2 may enable concurrent transmission of data 315-b and SSB 310 during an SSB opportunity (e.g., FDM). For example, data 315-b and SSB 310 may be transmitted during transmission 210-a (e.g., SCS #2). Figure 2 As shown) are transmitted concurrently (e.g., via FDM, where the waveforms are generated based on the same SCS for both data 315-b and SSB 310).

[0166] After the SSB opportunity, data 315 may switch back to SCS#1. For example, data 315-a may switch back to its default SCS after the SSB opportunity. Data 315 may switch between SCS#1 and SCS#2 due to active BWP 320-b supporting at least two parameter designs. For example, active BWP 320-b may be associated with a first parameter design supporting SCS#1 and a second parameter design supporting SCS#2 (e.g., when an SSB opportunity, SSB burst, etc. is identified or configured within active BWP 320-b).

[0167] The SCS configuration 303 may illustrate an example where the SSB 310 is outside the active BWP 320-b, while the data 315 may be transmitted within the active BWP 320-b. For example, the SSB 310 may be expected to be outside the active BWP 320-b. In these cases, the SCS of the data 315 may be adapted to the SCS of the SSB 310 and may be transmitted / received concurrently with the SSB 310, but the data 315 and the SSB 310 may not be FDMed. For example, the base station 105 or the UE 115 may identify the timing of the SSB 310 and the SCS#1 of the data 315-a may be adapted to the SCS#2 of the SSB 310 during the SSB 310 timing. After the SSB 310 timing, the data 315 may be switched from SCS#2 back to SCS#1. For example, the SCS of data 315 may be switched from the SCS of SSB 310 back to the default SCS of data 315 based on the configuration of the active BWP 320 - b .

[0168] Figure 3C Example SCS configurations supporting automatic adaptation of data SCS parameter design based on SSB transmissions in accordance with aspects of the present disclosure are illustrated. In some examples, SCS configuration 304 and SCS configuration 305 may be implemented to implement aspects of wireless communication system 100 or wireless communication system 200.

[0169] The SCS configuration 304 may illustrate an example where the SSB 310 is within the BWP 320-d. In these situations, the SCS may be adapted during the transmission of the data 315 according to the techniques described herein. For example, a first SCS (e.g., SCS #1) may be used for the transmission of the data 315-a during the default BWP 320-c. During the transmission of the SSB 310 within the BWP 320-d (e.g., where the SSB 310 and the data 315-b are FDMed), the SCS may be adapted or updated so that a second SCS (e.g., SCS #2) may be used for the transmission / reception of both the SSB 310 and the data 315-b. That is, BWP switching between a default BWP 320-c (e.g., the active BWP 320 for data 315-a) and a BWP 320-d (e.g., the active BWP 320 for FDM of data 315-b and SSB 310) may be employed to facilitate SCS adaptation, as described in more detail herein.

[0170] In some cases, the base station 105 and the UE 115 may identify the configuration for the SSB 310 and may switch the active BWP during transmission of the SSB 310. For example, the data 315-a may initially be transmitted in the default BWP 320-c via SCS#1 prior to transmission of the SSB 310. During transmission of the SSB 310, the BWP may automatically switch (e.g., without DCI indication) to support concurrent transmission of the data 315 and the SSB 310. In some cases, the BWP 320-d may be preferred for transmitting the data 315 and the SSB 310 based on the parameter design of the BWP 320-d (e.g., based on the SCS with which the BWP 320-d is configured with the SSB 310).

[0171] For example, a default BWP 320-c on which data 315-a is transmitted or received using SCS#1 other than when SSB 310 is transmitted may be automatically switched to BWP 320-d, and data 315-b and SSB 310 may be transmitted or received using SCS#2 on BWP 320-d when SSB 310 is transmitted. In some cases, the default BWP 320-c may be associated with a parameter design supporting SCS#1, and the BWP 320-d may be associated with a parameter design supporting SCS#2. For example, when the BWP is switched from the default BWP 320-c to the BWP 320-d, the data 315 may be automatically adapted from SCS#1 to SCS#2 based on the switching from the parameter design supporting SCS#1 to the parameter design supporting SCS#2. By switching to BWP 320-d, the data 315 and SSB 310 may be transmitted concurrently (e.g., may be FDM). In some cases, the default BWP 320-c may be other than the transmission of the SSB 310 (e.g., in Figure 2 210b) and BWP 320-d may be an active BWP during a transmission of SSB 310 (e.g., as shown in FIG. Figure 2 An active BWP during transmission 210-a as shown.

[0172] The SCS configuration 305 may illustrate an example where the SSB 310 is outside of an active BWP (e.g., outside of BWP 320-d). For example, the SSB 310 may be expected to be outside of BWP 320-d. In these cases, concurrent transmission / reception of the SSB 310 may be supported by adapting the SCS #1 of the data 315 to the SCS #2 of the SSB 310 by automatically switching from the default BWP 320-c to the BWP 320-d during BWP transmission in a manner similar to the SCS configuration 304.

[0173] Figure 4 An example of an SCS adaptation diagram that supports automatic adaptation of SCS parameter design for data based on SSB transmission according to various aspects of the present disclosure is shown. In some examples, the SCS adaptation diagram (400) can be implemented to implement various aspects of the wireless communication system 100 or the wireless communication system 200. The SCS adaptation diagram (400) can illustrate SSB codeword level switching of the SCS for adapting data. For example, the SSB burst 405 may include several SSB time slots 410 (e.g., time slots including at least some SSBs 440). In addition, each SSB time slot 410 (e.g., a time slot relative to the SSB) may include several codewords 415 (e.g., 14 codewords 415).

[0174] exist Figure 4In the example of , SSB burst 405 may include SSB 440 starting on symbol 415-a. Thus, SSB symbol boundary 435 associated with the beginning or starting boundary of symbol 415-a may be used as a switching point for adapting the SCS of data 445. That is, a first SCS (e.g., a default SCS for data) may be used for data 445-a in duration 430-a until SSB symbol boundary 435, at which symbol boundary point the SCS for data 445 may be adapted, reconfigured, switched, etc. to a second SCS (e.g., an SCS associated with SSB 440) for duration 430-b.

[0175] In some cases, symbol-level switching may be based on the different time domain structures of the data transmission 425 and the SSB burst 405. For example, in some cases, the data transmission 425 may be transmitted or received using an SCS of a first frequency (e.g., 3.84 MHz), while the SSB 440 may be transmitted / received using an SCS of a second frequency (240 kHz). In these cases, the data slot 420 may be a portion of the SSB slot 410 (e.g., the data slot 420 may be 1 / 16 of the duration of the SSB slot 410).

[0176] In some cases, due to their different time domain structures, the SSB symbol boundary 435 of the symbol 415 of the SSB burst 405 may not be aligned with the start or start boundary of the data slot 420. In these cases, the SSB burst 405 may start in a symbol 415-a, which may not be aligned with the boundary of the data slot 420 (e.g., in the time domain). To support concurrent transmission of SSB 440 and data 445, the SCS of the data 445 may be adapted to the SCS of the SSB 440 within the data slot 420. For example, the data 445-a (e.g., the data 445 transmitted with the default data SCS within the duration 430-a) may be adapted to the data 445-b (the data 445 transmitted with the SCS of the SSB 440 within the duration 430-b) at the SSB symbol boundary 435 according to the SSB 440 parameter design.

[0177] As an example illustration, data transmission 425-a may be an example data transmission that is not adaptable to the SCS of SSB 440 (e.g., data transmission 425-a using a default data SCS), while data transmission 425-b may be an example data transmission that may be adaptable to the SCS of SSB 440 at a switching point (e.g., at an SSB symbol boundary 435).

[0178] As reference FIG. 3A to FIG. 3CAs described, the timing for SSB burst 405 can be identified and the SCS of data 445 can be adapted to the SCS of SSB 440 during SSB burst 405. In some cases, data 445 can be transmitted during an active BWP (such as active BWP 320-b (e.g., FIG. 3A to FIG. 3C 440 within the active BWP. Thus, in these cases, the SCS of data 445 may be switched to the SCS of SSB 440 at SSB symbol boundary 435. In some cases, SCS switching within the active BWP may be based on the ability of the active BWP to support at least two parameter designs, each of which is associated with an SCS. For example, a first parameter design may be associated with a default SCS for data, and a second parameter design may be associated with an SCS for SSBs. In other cases, data 445 may be switched to the SCS of SSB 440 by switching the active BWP, such as from a default BWP 320-c to a BWP 320-d, such as FIG. 3A to FIG. 3C 440. For example, in these cases, the SCS of data 445 may be switched to the SCS of SSB 440 at SSB symbol boundary 435 based on switching the active BWP at the boundary.

[0179] Figure 5 An example of an SCS adaptation diagram that supports automatic adaptation of data SCS parameter design based on SSB transmission according to various aspects of the present disclosure is shown. In some examples, the SCS adaptation diagram (500) may be implemented to implement various aspects of the wireless communication system 100 or the wireless communication system 200. The SCS adaptation diagram (500) may illustrate SSB codeword level switching of the SCS for adapting data. For example, the SSB burst 505 may include several SSB time slots 510 (e.g., time slots including at least one SSB 540). In addition, each SSB time slot 510 (e.g., a time slot with respect to the parameter design of the SSB 540) may include several codewords 515 (e.g., 14 SSB codewords 515). In some cases, several SSB codewords 515 may include SSBs 540 that may be interleaved (e.g., different from being adjacent).

[0180] exist Figure 5In the example of , SSB burst 505 may begin in SSB slot 510-a (e.g., and in SSB symbol 515-a of SSB slot 510-a). Thus, SSB slot boundary 535 associated with the beginning or starting boundary of SSB slot 510-a may be used as a switching point for adapting the SCS of data 530. That is, a first SCS (e.g., a default SCS for data) may be used for data 530-a until SSB symbol boundary 535, at which point the SCS for data 530-b may be adapted, reconfigured, switched, etc. to a second SCS (e.g., an SCS associated with SSB 540).

[0181] In some cases, the time slot boundary switching may be based on the different time domain structures of the data transmission 525 and the SSB burst 505. For example, in some cases, the data transmission 525 may be transmitted or received using an SCS of a first frequency (e.g., 960 kHz), while the SSB 540 may be transmitted or received using an SCS of a second frequency (240 kHz). In these cases, the data time slot 520 may be a portion of the SSB time slot 510.

[0182] In some cases, due to their different time domain structures, SSB slot 510 may be aligned with data slot 520 from time to time. In these cases, the SCS of data 530 may be adapted to the SCS of SSB 540 at the aligned slot boundary (e.g., SSB slot boundary 535). For example, instead of switching at the first symbol including SSB 540, the SCS of data 530 may be switched to the SCS of SSB 540 at the beginning or boundary of the first slot including the symbol of SSB 540. Thus, data 530-a (including data 545-a transmitted via the default data SCS) may be adapted to data 530-b (e.g., including data 545-b having the SCS of SSB 540) at the symbol level of data transmission 425-b.

[0183] As an example illustration, data transmission 525-a may be an example data transmission that is not adaptable to the SCS of SSB 540 (e.g., data transmission 425-a using a default data SCS), while data transmission 525-b may be an example data transmission that may be adaptable to the SCS of SSB 540 at a switching point (e.g., at an SSB slot boundary 535).

[0184] As reference FIG. 3A to FIG. 3C As described, the timing for SSB burst 505 can be identified and the SCS of data 530 can be adapted to the SCS of SSB 540 during SSB burst 505. In some cases, data 530 can be transmitted during an active BWP (such as active BWP 320-b (e.g., FIG. 3A to FIG. 3CThus, in these cases, the SCS of data 530 may be switched to the SCS of SSB 540 at SSB symbol boundary 535. In some cases, SCS switching within an active BWP may be based on the ability of the active BWP to support at least two parameter designs, each of which is associated with an SCS. For example, a first parameter design may be associated with a default SCS for data, and a second parameter design may be associated with an SCS for SSBs. In other cases, data 445 may be switched to the SCS of SSB 540 by switching the active BWP, such as from a default BWP 320-c to a BWP 320-d, such as a BWP 320-d. FIG. 3A to FIG. 3C 440. For example, in these cases, the SCS of data 445 may be switched to the SCS of SSB 440 at SSB symbol boundary 435 based on switching the active BWP at the boundary.

[0185] Figure 6 An example of an SCS adaptation diagram that supports automatic adaptation of SCS parameter design for data based on SSB transmission according to various aspects of the present disclosure is illustrated. In some examples, the SCS adaptation diagram (600) can implement various aspects of the wireless communication system 100 or the wireless communication system 200. The SCS adaptation diagram (600) can illustrate SSB burst-level switching of the SCS for adapting data. For example, the SSB burst 605 can be associated with an SSB burst boundary 620 (e.g., the SSB burst 605 can be associated with a starting SSB burst boundary 620-a and an ending SSB burst boundary 620-b) and the SCS adaptation for data can be configured according to the SSB burst boundary 620.

[0186] exist Figure 6In the example of , SSB burst 605 can be configured for one or more time slots. Thus, SSB burst boundary 620 can be associated with the beginning of the first time slot or the end of the last time slot associated with SSB burst 605 in some cases. SSB burst boundary 620 can be used as a switching point for adapting the SCS of data 445. That is, a first SCS (e.g., a default SCS#1 for data) can be used for data 615-a until SSB burst boundary 620-a, at which boundary point the SCS for data 615 can be adapted, reconfigured, switched, etc. to a second SCS for data 615-b (e.g., SCS#2 associated with SSB 610). Similarly, a second SCS (e.g., SCS#2 for SSB 610) can be used for data 615-b until SSB burst boundary 620-b, at which boundary point the SCS for data 615 can be adapted, reconfigured, switched, etc. to a first SCS for data 615-a (e.g., SCS#1). In some examples, SCS #1 may include a 960 kHz SCS and SCS #2 may include a 240 kHz SCS. Since SCS adaptation or configuration may be performed according to SSB burst boundary 620, data slot boundaries and SSB slot boundaries may be aligned at a switching point (e.g., a data SCS configuration point at SSB burst boundary 620).

[0187] Fig. 7A , 7B 7C illustrate example UE feedback diagrams supporting automatic adaptation of data SCS parameter design based on SSB transmission according to aspects of the present disclosure. In some examples, UE feedback diagram (700), UE feedback diagram (701), and UE feedback diagram (702) may be implemented to implement aspects of wireless communication system 100 or wireless communication system 200. As described herein, in some cases, the SCS of data 725 may vary (e.g., dynamically configured) within a BWP.

[0188] For example, a BWP may be associated with a data parameter design and an SSB parameter design, wherein the SCS, symbol duration, and cyclic prefix length for the BWP are based on the data parameter design (e.g., in portions or durations of the BWP without an SSB) and the SSB parameter design (e.g., in portions or durations of the BWP that include the SSB). In such cases, when an SSB 720 is transmitted (e.g., within an active BWP), the SCS of the SSB may be used for the SCS of the data (e.g., so that the SSB and FDM of the data use the SCS of the SSB). Otherwise, a default SCS for the data may be used in the case where the data (e.g., without an SSB) is transmitted (e.g., within an active BWP). UE feedback diagram (700), UE feedback diagram (701), and UE feedback diagram (702) may illustrate examples of how HARQ-ACK feedback may be configured in these cases where the SCS of the data 725 varies (e.g., is dynamically configured) within the BWP.

[0189] exist Fig. 7A In the example of UE feedback diagram (700), UE feedback configuration for HARQ-ACK feedback in a scenario where the SCS is not adapted within the BWP (e.g., in a scenario where there is no FDM between the SSB 720 and the data 725). The UE feedback diagram (700) further illustrates a UE feedback configuration for a slot pattern using a data slot 705 (e.g., defined relative to a data SCS (e.g., SCS#1) for data 725-a). The DCI 735 may include a K0 indication for scheduling the data 725 (e.g., a PDSCH opportunity) and a K1 indication for scheduling an uplink feedback opportunity for the corresponding data 725 (e.g., a duration 740 of the ACK / NACK 730 corresponding to the data 725). In the example UE feedback diagram (700), the K0 / K1 indication may be defined according to a slot pattern including the data slot 705 (e.g., because no data 725 is transmitted with the SSB 720). For example, DCI 735-a may indicate that a K0=1 value schedules data 725-a in the next data slot 705-a (e.g., 1 slot away from the data slot 705 associated with DCI 735-a) and a K1=6 value schedules an ACK / NACK 730 for data 725-a in duration 740 (e.g., 6 slots away from the scheduled data slot 705-a). As illustrated by UE feedback diagram (700), the K0 / K1 indication may be defined according to the slot mode of the data slot 705.

[0190] exist Figure 7BIn the example of , the UE feedback diagram (701) may illustrate a UE feedback configuration for HARQ-ACK feedback in a scenario where the SCS is adapted within the BWP (e.g., in a scenario where FDM exists between SSB 720 and data 725). The UE feedback diagram (701) further illustrates a UE feedback configuration for a slot pattern using a data slot 705 (e.g., defined relative to a data SCS (e.g., SCS#1) of data 725-a) and a virtual slot 715 (e.g., a virtual data slot defined relative to a data SCS (e.g., SCS#1) of data 725-a). For example, during SSB transmission, K0 / K1 may be defined in a virtual slot (e.g., where the virtual slot 715 may be defined relative to the SCS of the data, i.e., SCS#1). The duration of the virtual slots 715 during the SSB 720 transmission may be the same as the duration of the data slots 705 outside of the SSB 720 transmission (eg, the UE feedback diagram (701) may use a similar slot pattern as the UE feedback diagram (700) for FDM where the SSB 720 and data 725 are not present).

[0191] The DCI 735 may include a K0 indication for scheduling data 725 (e.g., a PDSCH opportunity) and a K1 indication for scheduling an uplink feedback opportunity (e.g., a duration 740 corresponding to an ACK / NACK 730 for the scheduled data 725) for the corresponding scheduled data 725. In the example UE feedback diagram (701), the K0 / K1 indication may be defined according to a slot pattern including a data slot 705 and a virtual slot 715. For example, the DCI 735-b may indicate that a K0=1 value schedules data 725-a in the next data slot 705-b (e.g., at 1 slot from the data slot 705 associated with the DCI 735-b) and a K1=6 value schedules an ACK / NACK 730 for data (e.g., data scheduled in the data slot 705-b) in the duration 740 (e.g., at 6 slots from the scheduled data slot 705-b). As illustrated by the UE feedback diagram ( 701 ), the K0 / K1 indication may be defined according to a slot pattern of data slots 705 and virtual slots 715 .

[0192] exist Figure 7CIn the example of , the UE feedback diagram (702) may illustrate a UE feedback configuration for HARQ-ACK feedback in a scenario where the SCS is adapted within the BWP (e.g., in a scenario where FDM exists between SSB 720 and data 725). The UE feedback diagram (702) further illustrates a UE feedback configuration for a slot pattern using a data slot (e.g., defined by a data SCS (e.g., SCS#1) relative to data 725-a) and an SSB slot 710 (e.g., defined by an SSB SCS (e.g., SCS#2) relative to SSB 720 and data 725-b). For example, during SSB 720 transmission, K0 / K1 may be defined in the actual slot (e.g., in data slot 705 or SSB slot 710, depending on whether the SSB is being transmitted in that slot). The slot duration during SSB 720 transmission (e.g., SSB slot 710) may be different from the slot duration outside of SSB 720 transmission (e.g., data slot 705). When the SCS of SSB 720 is M and the SCS of data 725 is N, the actual slot duration during the SSB may become

[0193]

[0194] For example, if the SCS of SSB 720 is 480kHz and the SCS of data 725 is 1.92MHz, then:

[0195] Actual time slot 715 duration = 4*{time slot duration of data SCS}

[0196] The DCI 735 may include a K0 indication for scheduling data 725 (e.g., a PDSCH opportunity) and a K1 indication for scheduling an uplink feedback opportunity (e.g., a duration 740 corresponding to an ACK / NACK 730 for the scheduled data 725) for the corresponding scheduled data 725. In the example UE feedback diagram (702), the K0 / K1 indication may be defined according to a slot pattern including a data slot 705 and an SSB slot 710. For example, a DCI 735-c may indicate that a K0=1 value schedules data 725-a in the next data slot 705-c (e.g., 1 slot from the data slot 705 associated with the DCI 735-c) and a K1=3 value schedules an ACK / NACK 730 for data (e.g., data scheduled in the data slot 705-c) in the duration 740 (e.g., 3 slots from the scheduled data slot 705-c). As illustrated by the UE feedback diagram ( 702 ), the K0 / K1 indication may be defined according to the slot pattern of data slots 705 and SSB slots 710 .

[0197] Figure 8An example of a UE feedback diagram supporting automatic adaptation of data SCS parameter design based on SSB transmission according to various aspects of the present disclosure is shown. In some examples, the UE adaptation diagram (800) may be implemented to implement various aspects of the wireless communication system 100 or the wireless communication system 200. The UE feedback diagram (800) may illustrate UE feedback generation (e.g., HARQ-ACK codebook design) based on a virtual time slot mode defined by a default SCS relative to data in a BWP. For example, the codebook may be designed for a first CC (e.g., CC 805) and a second CC (e.g., CC 810). CC 805 may be associated with two configured indications of ACK / NACK 835. For example, CC 805 may be associated with a first indication of ACK / NACK 835 for data 830-a transmitted in a time slot 815 (e.g., without SSB 825) and a second indication of ACK / NACK 835 for data 830-b transmitted in a virtual time slot 820 (e.g., with SSB 825). In some examples, both time slot 815 and virtual time slot 820 may be defined based on the SCS of data 830 - a (e.g., a default SCS for the data).

[0198] A CC 810 (e.g., where the location of the SSB 825 is different from or outside of the CC 810) may be associated with three configured indications of ACK / NACK 835. For example, the CC 810 may include three slots 815 including data 830-a and lacking the SSB 825, and the three indications of ACK / NACK 835 may be associated with the three slots 815 including the data 830-a. Thus, the slots 815 may be defined according to the SCS of the data 830-a (e.g., the default SCS of the data). As illustrated by the UE feedback diagram (800), the information bits highlighted by the area 840 in the codebook may correspond to the FDM of the SSB 825 and the data 830-b. In some cases, all bits except the bits associated with K1=4 may be set to NACK. In other cases, the ACK or NACK at K1=4 may be repeated within the area 840 (e.g., which may improve feedback reliability).

[0199] Fig. 9An example of a UE feedback diagram that supports automatic adaptation of data SCS parameter design based on SSB transmission according to various aspects of the present disclosure is illustrated. In some examples, the UE adaptation diagram (900) can be implemented to implement various aspects of the wireless communication system 100 or the wireless communication system 200. The UE feedback diagram (800) can illustrate UE feedback generation (e.g., HARQ-ACK codebook design) based on time slots during SSB 925 transmission (e.g., SCS definition relative to SSB 925). For example, the codebook can be designed for a first CC (e.g., CC 905) and a second CC (e.g., CC 910). CC 905 can be associated with two configured indications of ACK / NACK 935. For example, CC 905 may be associated with a first indication of ACK / NACK 935 for data 935-a transmitted in time slot 915 (e.g., without SSB 930) and a second indication of ACK / NACK 935 for data 925-b transmitted in time slot 920 (e.g., with SSB 925). In some examples, time slot 915 may be defined according to an SCS of data 930-a (e.g., a default SCS for the data) and time slot 920 may be defined according to an SCS of SSB 925.

[0200] A CC 910 (e.g., where the location of the SSB 925 is different from or outside of the CC 910) may be associated with three configured indications of the ACK / NACK 935. For example, the CC 910 may include three slots 915 including data 930-a and lacking the SSB 925, and the three indications of the ACK / NACK 935 may be associated with the three slots 915 including the data 930-a. Thus, the slots 915 may be defined according to the SCS of the data 930-a (e.g., the default SCS of the data). As illustrated by the UE feedback diagram (900), the information bits highlighted by the region 940 in the codebook may correspond to the FDM of the SSB 925 and the data 930-b. Since there is no ambiguity in this region 940 between the UE and the base station, the UE may omit this region 940 in the codebook (e.g., the UE may feedback 9 bits instead of 12 bits by omitting 3 bits of the region 940 from the codebook). When SSB 925 is transmitted in a CC within the time span of the codebook, bits in the redundant region (eg, region 940) may not be fed back (eg, this may reduce feedback overhead).

[0201] Fig. 10A and 10BExample BWP configurations supporting automatic adaptation of data SCS parameter designs based on SSB transmissions according to various aspects of the present disclosure are illustrated. In some examples, BWP configuration 1000 and BWP configuration 1001 may be implemented to implement various aspects of wireless communication system 100 or wireless communication system 200. As discussed herein, in some cases, BWP 1015 may be automatically (e.g., without DCI indication) switched within and outside of SSB bursts. For example, a wireless communication system may employ separate BWPs 1015 for data and for FDM of SSB and data, wherein BWP 1015-b (e.g., a first BWP) may be associated with an SSB parameter design (e.g., an SSB SCS) and BWP 1015-a (e.g., a second BWP) may be associated with a data parameter design (e.g., a data SCS).

[0202] exist Fig. 10A In the example of FIG. 1 , BWP configuration 1000 may illustrate configuration of a time delay before switching from BWP 1015-b (e.g., an active BWP for FDM of SSB and data) to BWP 1015-a (e.g., an active BWP for data). That is, BWP configuration 1000 may implement a time delay (ΔT) 1025 after an SSB burst 1020 before switching from an SSB SCS (e.g., SCS #2) to a data SCS (e.g., SCS #1).

[0203] For example, BWP 1015-a (e.g., an active BWP) can support communication of data 1010-a (e.g., first data information) using a data SCS (e.g., SCS#1). When SSB 1005 is configured (e.g., when SSB burst 1020 is configured, when SSB opportunity is configured, etc.), BWP 1015-b can be activated (e.g., automatically activated based on SSB 1005 without DCI indication). BWP 1015-b (e.g., an active BWP) can then support communication of SSB 1005 and data 1010-b via FDM, where both SSB 1005 and data 1010-b use the same SSB SCS (e.g., SCS#2). However, in some cases, after SSB burst 1020 (e.g., after SSB 1005), time delay 1025 may be used before switching back to BWP 1015-a to communicate data 1010-a using SCS #1. In these cases, the data information communicated during time delay 1025 may still be configured with SSB SCS (SCS #2).

[0204] That is, the switchback point from BWP 1015-b (the BWP including the SSB 1005) to BWP 1015-a (e.g., the default BWP) may occur at a time delay 1025 (ΔT) after the completion of the SSB 1005 transmission. Thus, the base station may clear all HARQ A / Ns after the SSB burst 1020 and during the time delay 1025 (e.g., the base station may process the HARQ A / Ns according to the present disclosure, for example, with reference to Figures 7A to 9 1025). The time delay 1025 may provide additional time for the base station 105 to process the A / N before switching to the BWP 1015-a (e.g., the default BWP). For example, the time delay 1025 may provide sufficient time (e.g., when there is only downlink during SSB transmission and the A / N cannot be reported during SSB transmission). Thus, in a scenario where the BWP is switched for FDM of SSB and data, the UE and the base station may determine the time delay 1025 after the SSB 1005 (e.g., after the SSB burst 1020) and may configure the data SCS#1 (e.g., the active BWP 1015-a) after the time delay 1025. In some cases, the time delay 1025 may be determined based on a processing time associated with the HARQ-ACK feedback (e.g., based on the base station's processing time for the HARQ-ACK feedback transmitted by the UE). For example, in some cases, the base station may decide the switching point depending on the HARQ process (e.g., the range or number of HARQ processes) in the BWP 1015-b that includes the SSB 1005. In some cases, the time delay 1025 may be preconfigured by the wireless communication system or may be indicated by the base station to the UE (e.g., via DCI).

[0205] exist Fig. 10B In the example of , BWP configuration 1001 may illustrate the configuration of BWP 1015-b (e.g., the active BWP during SSB 1005 transmission). Fig. 10BIn some examples, BWP 1015-b may be configured at a smaller bandwidth than BWP 1015-a (e.g., because the SCS for both SSB and data may scale less for BWP 1015-b than the SCS for data outside of BWP 1015-b). Typically, the bandwidth of the SSB BWP may be configured as the same bandwidth as the default BWP, or may be configured with a different bandwidth than the default BWP. In some examples, the configuration of BWP 1015-b may be indicated (e.g., by the base station to the UE) semi-statically (e.g., via RRC or MAC-CE). The configuration of BWP 1015-b may include a time delay 1025 value for BWP 1015-b, a bandwidth for BWP 1015-b, an SCS for BWP 1015-b, a symbol duration for BWP 1015-b, a cyclic prefix length for BWP 1015-b, or any other configuration parameter for BWP 1015-b.

[0206] Fig.11 An example of a process flow for automatically adapting a data SCS parameter design based on an SSB transmission in accordance with various aspects of the present disclosure is illustrated. In some examples, the process flow 1100 can implement aspects of the wireless communication system 100 or the wireless communication system 200. The process flow 1100 includes a base station 105 and a UE 115, and the base station 105 can be as in Figure 1 and 2 Shown and referenced in Figure 1 and 2 The example of base station 105 described above, UE 115 may be as shown in Figure 1 and 2 Shown and referenced in Figure 1 and 2 An example of a UE 115 is described. Process flow 1100 includes functions and communications implemented by base station 105 and UE 115 in the context of automatically adapting data SCS parameter design based on SSB transmission (e.g., FDM for SSB and data using SSB SCS).

[0207] In the following description of process flow 1100, the operations between base station 105 and UE 115 may be communicated in an order different from that shown, or the operations may be performed in a different order or at a different time. Some operations may also be excluded from process flow 1100, or other operations may be added to process flow 1100. It will be understood that although base station 105 and UE 115 are shown as performing several operations of process flow 1100, any wireless device may perform the operations shown.

[0208] At 1105-a and 1105-b, UE 115 and base station 105 may respectively configure a first SCS (e.g., SCS#1). For example, at 1105-a, UE 115 may configure a modem, a radio frequency (RF) circuit system, etc. to receive a transmission (e.g., data at 1110) using the first SCS. In some examples, configuring a modem, an RF circuit system, etc. to receive a transmission using a certain SCS may refer to tuning the RF circuit system in the frequency domain to receive communications transmitted according to the SCS, determining one or more time periods for decoding communications transmitted according to the SCS, etc., so that communications can be received according to the configured SCS (e.g., according to the configured modem, RF circuit system, etc.).

[0209] At 1110, the base station 105 may transmit first data information to the UE 115 using the first SCS.

[0210] At 1115, the base station 105 may transmit downlink signaling including an indication of the SSB in the first BWP to the UE 115. In some cases, the indication of the SSB in the first BWP may be transmitted via RRC signaling. In some cases, the downlink signaling may refer to a DCI on a PDCCH (e.g., the DCI may include an indication of the SSB in the first BWP).

[0211] At 1120-a and 1120-b, UE 115 and base station 105 may respectively configure a second SCS (e.g., SCS#2). For example, at 1120-a, UE 115 may determine the second SCS based on the indication received at 1115. The indication of the SSB in the first BWP may be received at any time. For example, the indication of the SSB may be communicated semi-statically (e.g., via RRC signaling), wherein the indication of the SSB may refer to the configured SSB opportunity, the indication of the SSB may be communicated dynamically (e.g., via DCI), wherein the indication of the SSB may refer to an updated configuration for at least one SSB opportunity, and so on. Thus, 1120-a and 1120-b may be performed before any identified SSB transmission. In addition, in some cases, the SSB indication at 1115 may be received by UE 115 at any time (e.g., before 1105).

[0212] As discussed herein, the configuration at 1120 (e.g., at 1120-a or 1120-b) may occur at an identified symbol boundary associated with the SSB (e.g., at an SSB symbol boundary), at an identified slot boundary associated with the SSB (e.g., where the slot boundary may be identified based on the second SCS), at an identified SSB block burst boundary, etc. Switching boundaries regarding when to configure the second SCS (e.g., the SSB SCS) are described in greater detail herein (e.g., including at least at Figures 4 to 6 ).

[0213] At 1125, the base station 105 may use the second SCS to transmit the SSB and the second data information simultaneously, and the UE 115 may use the second SCS to receive the SSB and the second data information simultaneously. That is, according to some implementations of the present disclosure, the UE 115 and the base station 105 may adapt or dynamically configure the SCS of the data at 1110 and 1125. For example, the UE 115 may receive the first data information transmitted by the base station 105 at 1110 using the first SCS. The UE 115 may receive a DCI including an indication of a synchronization signal (e.g., SSB) in the first BWP on the PDCCH at 1115, and the UE 115 may determine the second SCS (e.g., the SCS of the SSB) based on the indication. Thus, the UE 115 may receive the synchronization signal and the second data information transmitted using the determined second SCS simultaneously at 1125.

[0214] In some examples, the SCS of the data can vary (e.g., dynamically configured) within a BWP (e.g., within a first BWP). For example, the first BWP can be associated with a data parameter design and an SSB parameter design, wherein the SCS, symbol duration, and cyclic prefix length used for the BWP are based on the data parameter design (e.g., in portions or durations of the BWP without an SSB, such as for receiving the first data information at 1110) and the SSB parameter design (e.g., in portions or durations of the BWP that include the SSB, such as for receiving the SSB and second data information at 1125).

[0215] In some other examples, the BWP can be switched automatically (e.g., without DCI indication) inside and outside the SSB burst. For example, the process flow 1100 can use separate BWPs for data at 1110 and for FDM of SSB and data at 1125. In such examples, the second BWP (e.g., active at 1110) can be associated with a data parameter design (e.g., where the data SCS, data symbol duration, and data cyclic prefix length for the BWP are based on the data parameter design) and the first BWP (e.g., active at 1125) can be associated with an SSB parameter design (e.g., where the SSB SCS, SSB symbol duration, and SSB cyclic prefix length for the BWP are based on the SSB parameter design). Thus, the second BWP can be used to receive the first data information at 1110 and the first BWP can be used to receive the SSB and the second data information at 1125.

[0216] In some examples, at 1130-a and 1130-b, UE 115 and base station 105 may respectively configure a first SCS (e.g., SCS#1). At 1135, base station 105 may use SCS#1 to transmit data.

[0217] In some examples, at 1140, UE 115 may generate a UE feedback report (e.g., a downlink feedback report) for the first data information and the second data information. For example, at 1140, UE 115 may determine a first position (K0) corresponding to the second data information based on the received DCI and determine a second position (K1) corresponding to an uplink feedback opportunity associated with the second data information (e.g., wherein the uplink feedback report is generated based on the first SCS, or the second SCS, or both). In some cases, the first position and the second position are determined based on a time slot mode (e.g., a virtual time slot mode) defined according to the first SCS. In some cases, the first position and the second position are determined based on a time slot mode defined according to the determined second SCS (e.g., wherein a time slot configured according to the second SCS can be skipped in the time slot mode). In some cases, the uplink feedback report may include a HARQ-ACK codebook.

[0218] At 1145, UE 115 may transmit a UE feedback report (eg, generated at 1140) to base station 105. Additional details regarding various aspects of the described techniques shown at 1140 and 1145 may be found throughout this specification, including at least Figure 7A-9 .

[0219] Fig.12A block diagram of a device that supports automatic adaptation of data SCS parameter design based on SSB transmission according to various aspects of the present disclosure is shown. The block diagram (1200) of the device 1205 can be an example of a device that supports automatic adaptation of data SCS parameter design based on SSB transmission. The device 1205 can be an example of various aspects of the UE 115 as described herein. The device 1205 may include a receiver 1210, a communication manager 1215, and a transmitter 1220. The device 1205 may also include a processor. Each of these components may be in communication with each other (e.g., via one or more buses).

[0220] The receiver 1210 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 automatic adaptation of data SCS parameter design based on SSB transmission, etc.). The information may be passed to other components of the device 1205. The receiver 1210 may be a transceiver 1520 (e.g., Fig.15 Receiver 1210 may utilize a single antenna or a set of antennas.

[0221] The communication manager 1215 may receive the first data information transmitted using the first SCS, determine the second SCS based on the indication, receive downlink signaling including an indication of a synchronization signal in the first BWP, and concurrently receive the synchronization signal and the second data information transmitted using the determined second SCS. The communication manager 1215 may be an example of aspects of the communication manager 1510 described herein.

[0222] The communication manager 1215 or its subcomponents may be implemented in hardware, in code (e.g., software or firmware) executed by a processor, or any combination thereof. If implemented in code executed by a processor, the functions of the communication manager 1215 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 the present disclosure.

[0223] The communication manager 1215 or its subcomponents may be physically located at various locations, including being distributed such that portions of 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 1215 or its subcomponents may be separate and distinct components. In some examples, according to various aspects of the present disclosure, the communication manager 1215 or its subcomponents may 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.

[0224] The transmitter 1220 can transmit signals generated by other components of the device 1205. In some examples, the transmitter 1220 can be co-located with the receiver 1210 in a transceiver component. For example, the transmitter 1220 can be a transceiver 1520 (e.g., Fig.15 Transmitter 1220 may utilize a single antenna or a collection of antennas.

[0225] Fig.13 A block diagram of a device supporting automatic adaptation of data SCS parameter design based on SSB transmission according to various aspects of the present disclosure is shown. The block diagram (1300) of device 1305 can be an example of a device supporting SSB SCS parameter design adaptation. Device 1305 can be an example of various aspects of device 1205 or UE 115 as described herein. Device 1305 may include a receiver 1310, a communication manager 1315, and a transmitter 1335. Device 1305 may also include a processor. Each of these components may be in communication with each other (e.g., via one or more buses).

[0226] The receiver 1310 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 automatic adaptation of data SCS parameter design based on SSB transmission, etc.). The information may be passed to other components of the device 1305. The receiver 1310 may be a transceiver 1520 (e.g., Fig.15 Receiver 1310 may utilize a single antenna or a set of antennas.

[0227] The communication manager 1315 may be an example of aspects of the communication manager 1215 as described herein. The communication manager 1315 may include an SCS manager 1320, a DCI manager 1325, and a receiver manager 1330. The communication manager 1315 may be an example of aspects of the communication manager 1510 described herein.

[0228] The SCS manager 1320 may receive the first data information transmitted using the first SCS and determine the second SCS based on the indication. The DCI manager 1325 may receive downlink signaling including an indication of a synchronization signal in the first BWP. The receiver manager 1330 may concurrently receive the synchronization signal and the second data information transmitted using the determined second SCS.

[0229] The transmitter 1335 may transmit signals generated by other components of the device 1305. In some examples, the transmitter 1335 may be co-located with the receiver 1310 in a transceiver component. For example, the transmitter 1335 may be a transceiver 1520 (e.g., Fig.15 Transmitter 1335 may utilize a single antenna or a collection of antennas.

[0230] Fig.14 A block diagram (1400) of a communication manager 1405 supporting automatic adaptation of data SCS parameter design based on SSB transmission according to aspects of the present disclosure is shown. The communication manager 1405 can be an example of aspects of the communication manager 1215, the communication manager 1315, or the communication manager 1510 described herein. The communication manager 1405 may include an SCS manager 1410, a DCI manager 1415, a receiver manager 1420, a downlink feedback manager 1425, and a BWP monitoring manager 1430. Each of these components may communicate directly or indirectly with each other (e.g., via one or more buses).

[0231] The SCS manager 1410 may receive the first data information transmitted using the first SCS. In some examples, the SCS manager 1410 may determine the second SCS based on the indication. In some examples, the SCS manager 1410 may configure the modem of the UE from using the first SCS to using the second SCS determined based on the indication, wherein the synchronization signal and the second data information are received simultaneously based on the configuration. In some examples, the SCS manager 1410 may configure the modem from using the first SCS to using the determined second SCS within the first BWP, wherein the first data information, the synchronization signal, and the second data information are received within the first BWP.

[0232] In some examples, the SCS manager 1410 may identify a symbol boundary associated with the synchronization signal based on the indication, wherein the configuration is performed at the identified symbol boundary. In some examples, the SCS manager 1410 may identify a slot boundary associated with the synchronization signal based on the indication, wherein the configuration is performed at the identified slot boundary. In some examples, the SCS manager 1410 may identify an SSB burst boundary associated with the synchronization signal based on the indication, wherein the configuration is performed at the identified SSB burst boundary. In some cases, the slot boundary is identified based on the determined second SCS. In some cases, the second SCS includes a default SCS associated with the synchronization signal.

[0233] The DCI manager 1415 may receive downlink signaling including an indication of a synchronization signal in the first BWP. In some cases, the synchronization signal includes an SSB.

[0234] The receiver manager 1420 may concurrently receive a synchronization signal and a second data information transmitted using the determined second SCS. In some examples, the receiver manager 1420 may determine a time period for decoding the synchronization signal and the second data information based on the first BWP and the determined SCS, wherein the synchronization signal and the data information are received based on the determined time period. In some cases, the synchronization signal and the second data information are received based on an FDM scheme. In some cases, the reception of the second data information is temporally adjacent to the reception of the first data information.

[0235] The downlink feedback manager 1425 may determine a first position corresponding to the second data information based on the received downlink signaling. In some examples, the downlink feedback manager 1425 may determine a second position corresponding to an uplink feedback opportunity associated with the second data information. In some examples, the downlink feedback manager 1425 may generate an uplink feedback report for the first data information and the second data information, wherein the uplink feedback report is generated based on the first SCS, the second SCS, or both.

[0236] In some examples, the downlink feedback manager 1425 may determine a third position corresponding to the first data information, wherein the third position is determined based on a second time slot mode defined according to the first SCS. In some cases, the first position and the second position are determined based on a first time slot mode defined according to the first SCS. In some cases, the first position and the second position are determined based on a first time slot mode defined according to the determined second SCS.

[0238] Fig.15 A diagram of a system including a device that supports automatic adaptation of data SCS parameter design based on SSB transmission according to various aspects of the present disclosure is shown. The system (1500) includes a device 1505 that can support automatic adaptation of data SCS parameter design based on SSB transmission. The device 1505 can be an example of a device 1205, a device 1305, or a UE 115 as described herein or include components of these devices. The device 1505 may include components for two-way voice and data communications, including components for transmitting and receiving communications, including a communication manager 1510, an I / O controller 1515, a transceiver 1520, an antenna 1525, a memory 1530, and a processor 1540.

[0239] The communication manager 1510 may receive first data information transmitted using a first SCS, determine a second SCS based on the indication, receive downlink signaling including an indication of a synchronization signal in a first BWP, and concurrently receive the synchronization signal and second data information transmitted using the determined second SCS.

[0240] I / O controller 1515 can manage input and output signals for device 1505. I / O controller 1515 can also manage peripheral devices that are not integrated into device 1505. In some cases, I / O controller 1515 can represent a physical connection or port to an external peripheral device. In some cases, I / O controller 1515 can utilize an operating system, such as Or another known operating system. In other cases, I / O controller 1515 may represent or interact with a modem, keyboard, mouse, touch screen, or similar device. In some cases, I / O controller 1515 may be implemented as part of a processor. In some cases, a user may interact with device 1505 via I / O controller 1515 or via hardware components controlled by I / O controller 1515.

[0241] The transceiver 1520 may communicate bidirectionally via one or more antennas, wired or wireless links, as described herein. For example, the transceiver 1520 may represent a wireless transceiver and may communicate bidirectionally with another wireless transceiver. The transceiver 1520 may also include a modem to modulate packets and provide the modulated packets to an antenna for transmission, and demodulate packets received from an antenna.

[0242] In some cases, a wireless device may include a single antenna 1525. However, in some cases, the device may have more than one antenna 1525, which may be capable of transmitting or receiving multiple wireless transmissions concurrently.

[0243] Memory 1530 may include random access memory (RAM) and read-only memory (ROM). Memory 1530 may store computer-readable, computer-executable code or software 1535 including instructions that, when executed, cause the processor to perform the various functions described herein. In some cases, memory 1530 may include, among other things, a basic I / O system (BIOS) that may control basic hardware or software operations, such as interaction with peripheral components or devices.

[0244] Processor 1540 may include an intelligent hardware device (e.g., a general purpose processor, a DSP, a central processing unit (CPU), a microcontroller, an ASIC, an FPGA, a programmable logic device, discrete gate or transistor logic components, discrete hardware components, or any combination thereof). In some cases, processor 1540 may be configured to operate a memory array using a memory controller. In other cases, the memory controller may be integrated into processor 1540. Processor 1540 may be configured to execute computer-readable instructions stored in a memory (e.g., memory 1530) to cause device 1505 to perform various functions (e.g., functions or tasks that support automatic adaptation of data SCS parameter design based on SSB transmission).

[0245] The software 1535 may include instructions for implementing various aspects of the present disclosure, including instructions for supporting wireless communications. The software 1535 may be stored in a non-transitory computer-readable medium, such as a system memory or other type of memory. In some cases, the software 1535 may not be directly executed by the processor 1540, but may cause a computer (e.g., when compiled and executed) to perform the functions described herein.

[0246] By implementing the techniques described herein, device 1505 can achieve efficient configuration of the SCS for data, which can provide improved FDM for SSB and data. For example, the techniques described herein can provide reduced coding complexity at base station 105 and reduced decoding complexity at UE 115 (e.g., device 1505) for FDM of SSB and data using the same SCS (e.g., the time domain summation of two IFFT outputs with different parameter designs for FDM of SSB and data, which can result in increased complexity at the receiving device or the transmitting device). This can further provide more efficient modem operation of device 1505 (e.g., processor 1540 can save resources that were originally used for relatively complex decoding, so that the operation of processor 1540 can be optimized in the scenario of FDM of SSB and data). For example, the resources saved based on the reduced decoding complexity can be used for more efficient operation of device 1505 (e.g., for other tasks). Additionally or alternatively, the reduced decoding complexity may provide power savings at device 1505, FDM for SSB and data may be provided to device 1505 with reduced decoding / processing capabilities (e.g., because device 1505 does not necessarily have to be able to decode a waveform having a time-domain summation of two IFFT outputs, each having different parameter designs for FDM for SSB and data), and the like.

[0247] Furthermore, an alternative to using the same SCS (e.g., SSB SCS) for FDM of SSB and data may include suppressing FDM of SSB and data (e.g., so that data is not sent when SSB is transmitted). However, the techniques described herein may provide such FDM of SSB and data, which may reduce latency associated with stalled data in scenarios where data is not sent for some reason when SSB is transmitted. Thus, the techniques described herein may provide reduced latency compared to suppressing FDM of SSB and data, which may facilitate emergency downlink communications while maintaining reduced encoding / decoding complexity.
