[0001] This request claims the benefit of US Provisional Patent Application No. 62 / 419,409, entitled “BOUNDARY INDICATION IN UNIFIED SYNCHRONIZATION CHANNEL DESIGN”, filed November 8, 2016, and US Provisional Patent Application No. 62 / 419,398, entitled “SPLIT SYNCHRONIZATION SIGNAL CONFIGURATION FOR UNIFIED SYNCHRONIZATION USED IN DIFFERENT COMMUNICATION MODES”, filed on November 8, 2016, and US Non-Provisional Patent Application No. 15 / 806,210, entitled “UNIFIED SYNCHRONIZATION CHANNEL DESIGN USED IN DIFFERENT COMMUNICATION MODES”, filed on November 7, 2017, the descriptions of which are incorporated herein by reference in their entirety as if fully set forth below and for all applicable purposes. TECHNICAL FIELD

[0002] Aspects of the present description generally relate to wireless communication systems and, more particularly, to synchronization signal design for unified synchronization channels and communication block boundary indication in a wireless communication system. Certain embodiments of the technology discussed below allow the same synchronization signal design to be used in different communication modes (or numerologies) and to provide efficient signal detection and processing in a wireless communication system. INTRODUCTION

[0003] Wireless communication networks are Petition 870240084234, dated 02 / 10 / 2024, page 6 / 63 2 / 51 Widely installed to provide various communication services, such as voice, video, packet data, messaging, broadcasting, and the like. These wireless networks can be multiple access networks capable of supporting multiple users by sharing available network resources. Such networks, which are generally multiple access networks, support communications for multiple users by sharing available network resources.

[0004] A wireless communication network can include several base stations or B nodes that can support communication to various user equipment (UEs). A UE can communicate with a base station via downlink and uplink. Downlink (or forward link) refers to the communication link from the base station to the UE, and uplink (or reverse link) refers to the communication link from the UE to the base station.

[0005] A base station can transmit data and control information on the downlink to a UE and / or can receive data and control information on the uplink from the UE. On the downlink, a transmission from the base station may encounter interference due to transmissions from neighboring base stations or other wireless radio frequency (RF) transmitters. On the uplink, a transmission from the UE may encounter interference from uplink transmissions from other UEs communicating with neighboring base stations or from other wireless RF transmitters. This interference can impair performance on both the downlink and uplink. Petition 870240084234, dated 02 / 10 / 2024, page 7 / 63 3 / 51

[0006] As the demand for mobile broadband access continues to increase, the possibilities of interference and congested networks grow, with more EUs accessing long-range wireless communication networks and more short-range wireless systems being installed in communities. Research and development continue to advance wireless communication technologies, not only to meet the growing demand for mobile broadband access, but to promote and improve the user experience with mobile communications.

[00029] The detailed description set forth below, in connection with the accompanying drawings, is intended to describe various possible configurations and is not intended to limit the scope of the description. Instead, the detailed description includes specific details for the purpose of providing a complete understanding of the subject matter. It will be evident to those skilled in the art that these specific details are not necessary in all cases and that, in some cases, well-known structures and components are shown in block diagram form for clarity of presentation.

[00030] This description generally refers to Petition 870240084234, dated 02 / 10 / 2024, page 16 / 63 12 / 51 To provide or participate in communication between two or more wireless nodes (e.g., base stations, user devices, access points, terminal devices, etc.) in one or more wireless communication systems, also referred to as wireless communication networks. In various embodiments, techniques and apparatus can be used for wireless communication networks, such as Code Division Multiple Access (CDMA) networks, Time Division Multiple Access (TDMA) networks, Frequency Division Multiple Access (FDMA) networks, Orthogonal FDMA (OFDMA) networks, Single Carrier FDMA (SCFDMA) networks, Long Term Evolution (LTE) networks, Global System for Mobile Communications (GSM) networks, as well as other communication networks. As described herein, the terms networks and systems may be used interchangeably according to the particular context.

[00031] A CDMA network, for example, can implement a radio technology such as Universal Terrestrial Radio Access (UTRA), cdma2000 and similar technologies. UTRA includes wideband CDMA (W-CDMA) and low chip rate (LCR). CDMA2000 encompasses the IS-2000, IS-95 and IS856 standards.

[00032] A TDMA network can, for example, implement a radio technology such as GSM. 3GPP defines standards for the GSM EDGE (GMS Enhanced Data Rates for Evolution) radio access network (RAN), also called GERAN. GERAN is the radio component of GSM / EDGE, along with the network that connects base stations (e.g., Ater and Abis interfaces) and base station controllers (A interfaces, etc.). The access network by Petition 870240084234, dated 02 / 10 / 2024, page 17 / 63 13 / 51 radio represents a component of a GSM network, through which telephone calls and packet data are routed to and from the public switched telephone network (PSTN) and the Internet to and from subscriber portable devices, also known as user terminals or user equipment (UEs). A mobile operator network may comprise one or more GERANs, which may be coupled to Universal Terrestrial Radio Access Networks (UTRANs) in the case of a UMTS / GSM network. An operator network may also include one or more LTE networks and / or one or more other networks. The various different network types may use different radio access technologies (RATs) and radio access networks (RANs).

[00033] An OFDMA network can, for example, implement a radio technology such as evolved UTRA (E-UTRA), IEEE 802.11, IEEE 802.16, IEEE 802.20, OFDM flash, and the like. UTRA, E-UTRA, and GSM are part of the Universal Mobile Telecommunication System (UMTS). In particular, LTE is a release of UMTS that uses E-UTRA. UTRA, E-UTRA, GSM, UMTS, and LTE are described in documents provided by an organization called the “3rd Generation Partnership Project” (3GPP), and cdma2000 is described in documents from an organization called the “3rd Generation Partnership Project 2” (3GPP2). These various radio technologies and standards are known or are being developed. For example, the 3rd Generation Partnership Project (3GPP) is a collaboration between groups of telecommunications associations that aims to define a globally applicable third-generation (3G) mobile phone specification. The Long Term Evolution (LTE) 3GPP is a 3GPP project that aims to improve the Petition 870240084234, dated 02 / 10 / 2024, page 18 / 63 3GPP is the Universal Mobile Telecommunication System (UMTS) mobile phone standard. 3GPP can define specifications for the next generation of mobile networks, mobile systems, and mobile devices.

[00034] For clarity, certain aspects of the apparatus and techniques may be described below with reference to exemplary LTE implementations or in an LTE-centric manner, and LTE terminology may be used as illustrative examples in parts of the description below; however, the description is not intended to be limited to LTE applications. In fact, the present description refers to shared wireless spectrum access between networks using different radio access technologies or radio air interfaces.

[00035] Furthermore, it should be understood that, in operation, wireless communication networks adapted according to the concepts contained herein can operate with any combination of licensed or unlicensed spectrum, depending on the load and availability. Consequently, it will be evident to one skilled in the art that the systems, apparatus, and methods described herein can be applied to communication systems and applications other than the particular examples provided.

[00036] Although the aspects and forms of implementation are described in this application by way of illustration for a few examples, those skilled in the art will understand that additional implementations and use cases may arise in many different arrangements and scenarios. The innovations described herein can be implemented in many Petition 870240084234, dated 02 / 10 / 2024, page 19 / 63 15 / 51 different platform types, devices, systems, formats, sizes, packaging arrangements. For example, embodiments and / or uses may be realized through integrated chip embodiments and / or other devices based on non-module components (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, purchase / sale devices, medical devices, AI-enabled devices, etc.). While some examples may or may not be specifically targeted to use cases or applications, a wide variety of applicability of described innovations may occur. Implementations may range from chip-level components or modular components to non-modular, non-chip-level and additionally aggregated, distributed, or OEM devices or systems incorporating one or more described aspects.In some practical configurations, devices incorporating the described aspects and features may also necessarily include additional components and features for the implementation and practice of the claimed and described embodiments. It is intended that the innovations described herein can be implemented in a wide variety of implementations, including both large / small devices, chip-level components, multi-component systems (e.g., RF chain, communication interface, processor), distributed arrays, user devices, etc., of various sizes, shapes, and constitutions.

[00037] Figure 1 shows the 100 wireless network Petition 870240084234, dated 02 / 10 / 2024, page 20 / 63 16 / 51 for communication according to some embodiments. Although the discussion of the technology in this description is provided in relation to an LTE-A network (shown in Figure 1), this is for illustrative purposes. Principles of the technology described can be used in other network installations, including fifth-generation (5G) networks. As appreciated by those skilled in the art, the components appearing in Figure 1 are likely to have related counterparts in other network arrangements, including, for example, cellular-style network arrangements and non-cellular-style network arrangements (e.g., node-to-node or point-to-point or ad hoc network arrangements, etc.).

[00038] Returning to Figure 1, the 100 wireless network includes several base stations, which may comprise evolved B nodes (eNBs) or G B nodes (gNBs). These may be referred to as gNBs 105. A gNB may be a station that communicates with UEs and may also be referred to as a base station, a B node, an access point, and the like. Each gNB 105 may provide communication coverage for a particular geographic area. In 3GPP, the term cell may refer to this particular geographic coverage area of ​​a gNB subsystem and / or gNB serving the coverage area, depending on the context in which the term is used. In 100 wireless network implementations described here, the gNBs 105 may be associated with the same operator or different operators (e.g., the 100 wireless network may comprise a plurality of wireless network operators) and may provide wireless communications using one or more of the same frequencies (e.g., one or more Petition 870240084234, dated 02 / 10 / 2024, page 21 / 63 17 / 51 frequency bands in the licensed spectrum, unlicensed spectrum, or a combination thereof) as a neighboring cell.

[00039] A gNB can provide communication coverage for a macrocell or a small cell, such as a picocell or a femtocell and / or other cell types. A macrocell generally covers a relatively large geographic area (e.g., several kilometers in radius) and can allow unrestricted access by UEs with service subscriptions with the network provider. A small cell, such as a picocell, can generally cover a relatively smaller geographic area and can allow unrestricted access by UEs with service subscriptions with the network provider. A small cell, such as a femtocell, can also generally cover a relatively small geographic area (e.g., a house) and, in addition to unrestricted access, can also provide restricted access by UEs that have an association with the femtocell (e.g., UEs in a closed subscriber group (CSG), UEs for users in the house, and the like).A gNB for a macrocell can be referred to as a macro gNB. A gNB for a small cell can be referred to as a small-cell gNB, a pico gNB, a femto gNB, or a domestic gNB. In the example shown in Figure 1, gNBs 105a, 105b, and 105c are macro gNBs for macrocells 110a, 110b, and 110c, respectively. gNBs 105x, 105y, and 105z are small-cell gNBs that may include pico or femto gNBs that provide service for small cells 110x, 110y, and 110z, respectively. A gNB can support one or multiple cells (e.g., two, three, four, etc.). Petition 870240084234, dated 02 / 10 / 2024, p. 22 / 63 18 / 51 similar).

[00040] Wireless Network 100 can support synchronous or asynchronous operation. For synchronous operation, gNBs can have similar frame timing, and transmissions from different gNBs can be approximately time-aligned. For asynchronous operation, gNBs can have different frame timings, and transmissions from different gNBs may not be time-aligned. In some scenarios, networks can be enabled or configured to handle dynamic switching between synchronous and asynchronous operations.

[00041] The 115 UEs are dispersed throughout the 100 wireless network, and each UE can be stationary or mobile. It should be appreciated that, although a mobile device is commonly referred to as user equipment (UE) in standards and specifications promulgated by the 3rd Generation Partnership Project (3GPP), such equipment may also be referred to by those skilled in the art as a mobile station (MS), a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communications device, a remote device, a mobile subscriber station, an access terminal (AT), a mobile terminal, a wireless terminal, a remote terminal, a portable device, a terminal, a user agent, a mobile client, a client, or some other suitable terminology. Within the present document, a mobile device or UE does not necessarily need to have the ability to move and may be stationary.Some non-limiting examples of a mobile device, such as ways of carrying out... Petition 870240084234, dated 02 / 10 / 2024, page 23 / 63 19 / 51 one or more of EU 115, include a mobile phone, a cellular phone (mobile phone), a smartphone, a session initiation protocol (SIP) phone, a laptop, a personal computer (PC), a notebook, a netbook, a smart book, a tablet and a personal digital assistant (PDA). A mobile device may additionally be an Internet of Things (IoT) device, such as an automotive or other transport vehicle, a satellite radio, a global positioning system (GPS) device, a logistics controller, a drone, a multicopter, a quadcopter, a smart energy or security device, a solar panel or solar array, municipal lighting, water or other infrastructure; industrial automation and enterprise devices;Consumer and wearable devices, such as eyeglasses, a wearable camera, a smartwatch, a health or fitness tracker, a mammalian implantable device, a gesture tracking device, a medical device, a digital audio player (e.g., MP3 player), a camera, a game console, etc.; and digital home or smart home devices, such as a home audio, video, and multimedia device, a household appliance, a sensor, a vending machine, smart lighting, a home security system, a smart meter, etc. A mobile device, such as UEs 115, may be able to communicate with macro gNBs, pico gNBs, femto gNBs, relays, and the like. In Figure 1, a lightning bolt (e.g., communication links 125) indicates wireless transmissions between a UE and a gNB in ​​service, which is a gNB designated to serve the UE on the downlink; Petition 870240084234, dated 02 / 10 / 2024, page 24 / 63 20 / 51 and / or uplink, or desired transmission between gNBs. Although land link communication 134 is illustrated as wired land link communications that can occur between gNBs, it should be appreciated that land link communications can additionally or alternatively be provided by wireless communications.

[00042] Figure 2 shows a block diagram of a base station / gNB 105 and UE 115 project. These could be one of the base stations / gNBs and one of the UEs in Figure 1. For a restricted association scenario (as mentioned above), the gNB 105 could be the small-cell gNB 105z in Figure 1, and the UE 115 could be the UE 115z, which, in order to access small-cell gNB 105z, would be included in a list of UEs accessible to small-cell gNB 105z. The gNB 105 could also be a base station of some other type. The gNB 105 could be equipped with antennas 234a to 234t, and the UE 115 could be equipped with antennas 252a to 252r.

[00043] In gNB 105, transmission processor 220 can receive data from data source 212 and control information from controller / processor 240. The control information can be for the physical broadcast channel (PBCH), physical downlink control channel (PDCCH), etc. The data can be for the physical downlink shared channel (PDSCH), etc. Transmission processor 220 can process (e.g., encoding and symbol mapping) the data and control information to obtain data symbols and control symbols, respectively. Transmission processor 220 can also generate reference symbols, e.g., for Petition 870240084234, dated 02 / 10 / 2024, page 25 / 63 21 / 51 the primary synchronization signal (PSS) and the secondary synchronization signal (SSS). The multi-input multiple-output (MIMO) transmission (TX) processor 230 can perform spatial processing (e.g., pre-coding) on ​​data symbols, control symbols, and / or reference symbols, if applicable, and can provide continuous output symbol transfers to modulators (MODs) 232a to 232t. Each modulator 232 can process a respective continuous output symbol transfer (e.g., for OFDM, etc.) to obtain a continuous output sample transfer. Each 232 modulator can additionally or alternatively process (e.g., convert to analog, amplify, filter, and upconvert) the continuous output sample transfer to obtain a downlink signal. The downlink signals from modulators 232a to 232t can be transmitted via antennas 234a to 234t, respectively.

[00044] In UE 115, antennas 252a to 252r can receive downlink signals from gNB 105 and can provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 can condition (e.g., filter, amplify, down-convert, and digitize) a respective received signal to obtain input samples. Each demodulator 254 can further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. The MIMO detector 256 can obtain received symbols from all demodulators 254a to 254r, perform MIMO detection on the received symbols, if Petition 870240084234, dated 02 / 10 / 2024, p. 26 / 63 22 / 51 applicable, and provide detected symbols. The receiving processor 258 can process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data to the UE 115 to the data collector 260, and provide decoded control information to the controller / processor 280.

[00045] In the uplink, in UE 115, the transmission processor 264 can receive and process data (e.g., for the PUSCH) from the data source 262 and control information (e.g., for the PUCCH) from the controller / processor 280. The transmission processor 264 can also generate reference symbols for a reference signal. The symbols from transmission processor 264 can be pre-coded by MIMO TX processor 266, if applicable, further processed by modulators 254a to 254r (e.g., for SC-FDM etc.), and transmitted to gNB 105. On gNB 105, the uplink signals from UE 115 can be received by antennas 234, processed by demodulators 232, detected by MIMO detector 236, if applicable, and further processed by reception processor 238 to obtain decoded data and control information sent by UE 115.Processor 238 can provide decoded data to data collector 239 and decoded control information to controller / processor 240.

[00046] Controllers / processors 240 and 280 can direct operation in gNB 105 and UE 115, respectively. Controller / processor 240 and / or other processors and modules in gNB 105 and / or Petition 870240084234, dated 02 / 10 / 2024, page 27 / 63 Controllers / processor 280 and / or other processors and modules in UE 115 can perform or direct the execution of various processes for the techniques described herein, such as performing or directing the execution illustrated in Figures 4, 6, and 7, and / or other processes for the techniques described herein. Memories 242 and 282 can store data and program codes for gNB 105 and UE 115, respectively. Programmer 244 can program UEs for data transmission on the downlink and / or uplink.

[00047] By facilitating increased capacity, interference tolerance, robust performance, etc., wireless networks can support a plurality of communication modes for communications by and between various network nodes. For example, the 100 wireless network can support a plurality of different communication modes, which may utilize one or more different parameters (such as subcarrier spacing, frequency, frame structure, symbol length, OFDM symbol times, sample rates, etc.). A particular communication mode may be selected for use in a communication link between a gNB and the UE, depending on various aspects of the situation (e.g., channel condition, received signal strength, interference environment, etc.). The different parameters used with respect to the communication modes are referred to here as numerologies.As an example of a different numerology that can be implemented according to the embodiments of the present description, the 100 wireless network operable according to the 5G protocols currently under development can. Petition 870240084234, dated 02 / 10 / 2024, page 28 / 63 24 / 51 supports communication modes with different subcarrier spacings (e.g., 15 kHz, 30 kHz, 60 kHz, etc., subcarrier spacing).

[00048] Although the communication modes may differ according to the previous numerologies, the operable embodiments according to the concepts described herein may still utilize the same synchronization signal configuration (referred to herein as a unified synchronization signal configuration) with respect to two or more (e.g., all) of the different communication modes. For example, in order to facilitate network nodes (e.g., UEs) being able to detect a synchronization signal transmitted according to any of a plurality of communication modes (e.g., signals having any of the 15kHz, 30kHz, or 60kHz subcarrier spacing mentioned above) without first knowing the particular communication mode, the embodiments of the present description provide a unified synchronization signal configuration that can be supported by signals of each communication mode.However, due to differences in the signals of different communication modes (e.g., subcarrier spacing, symbol size, data payload, etc.), a unified synchronization signal configuration according to the embodiments described herein includes a split configuration, in which a predetermined interval is provided within the synchronization signal set adapted to facilitate the use of the same synchronization signal configuration in signals of multiple communication modes. For example, a set of signals of... Petition 870240084234, dated 02 / 10 / 2024, page 29 / 63 25 / 51 Synchronization embodiments may comprise a plurality of signals, such as two or more of: a PSS, an SSS, one or more signals transmitted by a PBCH and / or a reference signal (RS) (for example, which may be used as an RS measurement or an RS demodulation for PBCH signals). The synchronization signal set may be transmitted in a predetermined arrangement and have a predetermined interval arranged between two or more signals of the synchronization signal set.

[00049] Figure 3 shows a block diagram for a unified synchronization signal configuration of some embodiments, as it can be used in the 100 wireless network. The unified synchronization signal configuration can be used, for example, for communications between gNB 105 and UE 115, between gNBs 105a-c, or between several UEs. Figure 3 shows a unified synchronization signal configuration where the same synchronization signal configuration 302 can be used for different communication modes 310-2, 310-4, and 310-6 in a wireless communication network. In each communication mode of the illustrated embodiment, data communication between two nodes is divided into blocks, for example, frames (or subframes or slots) 320-2, 320-4, 320-6, and 320-8.Each communication block may include one or more units for control signals (e.g., control symbols 322, 324) and one or more units for data signals (e.g., data symbols 326) located between control signal units. In some embodiments, the control signals in communication blocks 320-2, 320-4, 320-6, and 320-8 may include one or more units (e.g., Petition 870240084234, dated 02 / 10 / 2024, page 30 / 63 26 / 51 example, 322) for downlink control signals (from a gNB to a UE) and / or one or more units (e.g., 324) for uplink control signals (from a UE to a gNB). In some wireless communication systems, a communication block may represent a frame, two consecutive units in the communication block may represent a subframe (e.g., in a time-division duplex (TDD) or frequency-division duplex (FDD) system), and one unit in the communication block may represent a slot (e.g., in an FDD system). In some embodiments, a communication block may represent either a subframe or a slot.

[00050] In the illustrated example, each communication mode operates using a different subcarrier spacing; for example, communication mode 310-2 operates using a subcarrier spacing of 15 kHz, communication mode 310-4 operates using a subcarrier spacing of 30 kHz, and communication mode 310-6 operates using a subcarrier spacing of 60 kHz. Therefore, the numerology of the communication modes in the illustrated example comprises subcarrier spacing. Consequently, the communication blocks 320-2, 320-4, 320-6 and 320-8 for these different communication modes provide different symbol sizes and different spacings. For example, in the illustrated embodiment, the synchronization signal 304 occupies half a unit (e.g., half a symbol) in mode 310-2, one unit (e.g., one symbol) in mode 310-4, and two units (e.g., two symbols) in mode 310-6.

[00051] In the illustrated embodiment, the Petition 870240084234, dated 02 / 10 / 2024, page 31 / 63 The 27 / 51 synchronization signal configuration 302 includes an arrangement of multiple synchronization signals 304, also referred to as a synchronization signal block (SSB), which may include, for example, a PSS, SSS, RS, and signals transmitted by a PBCH. For example, in the illustrated embodiment, the SSB of the synchronization signal configuration 302 comprises a set of synchronization signals including a PSS followed by an SSS and an RS (e.g., an RS demod for PBCH which may also be used for cell measurements, referred to herein as a measurement reference signal or MRS), which is then followed by two PBCHs, an RS, and then two PBCH signals. It should be noted that in some other embodiments, the SSB of the synchronization signal configuration 302 may comprise a set of synchronization signals including any other combination of any number of synchronization signals in any suitable order.

[00052] In some embodiments, it is desirable that the synchronization signals 304 occupy only units assigned to data signals (i.e., any unfilled units, which are usually labeled 326) in the communication blocks 320-2, 320-4, 320-6, and 320-8 and avoid overlapping with units assigned to control signals (units 322 and 324). However, in some consecutive arrangements of synchronization signals, the consecutive block of synchronization signals cannot be filled in data units of a communication block in certain communication modes. For example, in the illustrated example, a consecutive arrangement of 304 synchronization signals cannot be set in the units of Petition 870240084234, dated 02 / 10 / 2024, page 32 / 63 28 / 51 data 326 in communication block 320-6 or in all in communication block 320-8. Consequently, to adapt the same synchronization signal configuration 302 for different communication modes, the embodiments insert one or more intervals (e.g., interval 306) between the SSB synchronization signals 304 of the synchronization signal configuration 302.As illustrated in Figure 3, the aperture 306 can be designed to separate synchronization signals 304 into two groups, such that one group of synchronization signals fits into data units 326 of communication block 320-6 and another group of synchronization signals fits into data units 326 of communication block 320-8. When the split synchronization signal configuration 302 is used in other communication modes, such as communication modes 320-2 and 320-4, since there is sufficient spacing in data units 326, all synchronization signals 304 can be fitted into data units of a communication block (e.g., communication blocks 320-2 or 320-4).With such a split synchronization signal configuration 302, the same multiple synchronization signal configuration can be used for different communication modes, and none of the synchronization signals in the 302 synchronization signal configuration occupy any units reserved for control signals (i.e., units 322, 324) in any communication mode.

[00053] It should be noted that, in some embodiments, several intervals may be used to separate the SSB synchronization signals into three or more groups, such that the various groups of signals of Petition 870240084234, dated 02 / 10 / 2024, page 33 / 63 29 / 51 synchronization fits into data units of different communication modes. For example, there may be more than three communication modes and there may be multiple intervals in the 302 synchronization signal configuration. Extending this example to a numerology comprising different subcarrier spacing as described above, there may be a fourth communication mode operating to utilize the 120 kHz subcarrier spacing, and it may be desirable to have two intervals for the 302 synchronization signal configuration so that the 304 synchronization signals of the SSB can be divided into three groups and fitted into data units of three consecutive communication blocks. Furthermore, the 302 synchronization signal configuration can be used in wireless communication systems that utilize frequency division duplexing (FDD) or time division duplexing (TDD).

[00054] Figure 4 shows a block diagram for a method 400 of determining a unified synchronization signal arrangement according to the embodiments of the present description. In the illustrated embodiment, in block 402 the unified synchronization signal logic (e.g., a set of instructions stored by memory 242 and executable in the controller / processor 240 of gNB 105) of a network node determines an arrangement of multiple synchronization signals for wireless communication between two or more nodes. The nodes may include a gNB, a UE, or other nodes in the wireless communications network 100 as described above in relation to Figure 1. The synchronization signals may, for example, include one or more of the following signals: PSS, SSS signals, Petition 870240084234, dated 02 / 10 / 2024, page 34 / 63 30 / 51 RS and PBCH. In block 404, the unified synchronization signal logic can cause one or more gaps to be inserted between two or more synchronization signals of the array (for example, a set of instructions stored by memory 242 and executable in the controller / processor 240 of gNB 105 can control the transmission processor 220 to insert one or more gaps between two or more synchronization signals to be transmitted by gNB 105). The one or more gaps can allow the same array of multiple synchronization signals to be used in multiple communication modes that operate using different numerologies, such as the 320-2, 310-4, 310-6 communication modes described above in connection with Figure 3.One or more gaps between synchronization signals in the multiple synchronization signal array may allow multiple synchronization signals to be fitted into data units of one or more communication blocks (such as communication blocks 320-2, 320-4, 320-6, 320-8 described in Figure 3) and avoid any overlap with units reserved for other control signals in one or more communication blocks.

[00055] The different numerologies mentioned above used by the communication modes can result in differences in the various blocks (e.g., frames) transmitted. For example, different numerologies corresponding to the subcarrier spacing can provide differences in the symbol lengths between the signals transmitted by the communication modes. Therefore, although a unified synchronization signal, such as that shown in the illustrated exemplary embodiment Petition 870240084234, dated 02 / 10 / 2024, page 35 / 63 31 / 51 in Figure 3, can be used for each of a plurality of communication modes; however, the unified synchronization signal may have differences depending on the arrangement in the blocks of each communication mode. For example, a unified synchronization signal, despite having the same predetermined arrangement of synchronization signals transmitted using each communication mode, may be arranged with a different boundary offset in the different communication modes. Consequently, a unified configuration of synchronization signals of embodiments, such as UE, can facilitate the detection of synchronization signals by a network node (e.g., UE), and can be adapted to facilitate the detection of a communication block of communication modes.

[00056] Figure 5 shows a block diagram to indicate a communication block boundary for a unified synchronization channel configuration that can be used in the 100 wireless network. The boundary indicator configurations can be used, for example, for communications between gNB 105 and UE 115, between gNBs 105a-c, or between multiple UEs. Figure 5 shows a configuration to indicate communication block boundaries (e.g., frames, subframes, or slots) for a unified synchronization signal configuration where the same 502 synchronization signal configuration is used for different 510-2, 510-4, and 510-6 communication modes in a wireless communication network. The synchronization signal configuration can, for example, have a fixed length in time when used in multiple communication modes, where the fixed length is selected to configure the Petition 870240084234, dated 02 / 10 / 2024, pp. 36 / 63 32 / 51 Synchronization signal configuration for multiple communication modes. The methods for implementing the synchronization signal configuration can utilize one or more intervals, as discussed above with reference to Figure 3, to configure the synchronization signal configuration for multiple communication modes.

[00057] In each communication mode, data communication between two nodes is divided into blocks, for example, frames (or subframes or slots) 520-2, 520-4, 520-6, and 520-8. Each communication block may include one or more units for control signals (e.g., control symbols 522, 524) and one or more units for data signals (e.g., data symbols 526) located between control signal units. In some embodiments, the control signals in communication blocks 520-2, 520-4, 520-6, and 520-8 may include one or more units (e.g., 522) for downlink control signals (from a gNB to a UE) and / or one or more units (e.g., 524) for uplink control signals (from a UE to a gNB).In some wireless communication systems, a communication block can represent a frame, two consecutive units in the communication block can represent a subframe (for example, in a time-division duplex (TDD) or frequency-division duplex (FDD) system), and a single unit in the communication block can represent a slot (for example, in an FDD system). In some embodiments, a communication block can represent either a subframe or a slot.

[00058] It should be appreciated that, although the form Petition 870240084234, dated 02 / 10 / 2024, page 37 / 63 The embodiment illustrated in Figure 5 shows a contiguous configuration of SSB synchronization signals; other synchronization signal configurations may be used with limit indication implementations of the present description. For example, a split SSB synchronization signal configuration, such as the exemplary embodiment illustrated in Figure 3, may be used with communication block limit indication implementations of the present description.

[00059] In the illustrated example, as in the example in Figure 3 above, each communication mode operates using a different subcarrier spacing; for example, the 510-2 communication mode operates using a subcarrier spacing of 15 kHz, the 510-4 communication mode operates using a subcarrier spacing of 30 kHz, and the 510-6 communication mode operates using a subcarrier spacing of 60 kHz. Consequently, the 520-2, 520-4, 520-6, and 520-8 communication blocks for these different communication modes provide different symbol sizes and different deviations from the communication block boundaries.

[00060] In the illustrated embodiment, the 502 synchronization signal configuration may include an arrangement of multiple 504 synchronization signals comprising an SSB, which may include, for example, a PSS, SSS, RS, and signals transmitted by a PBCH. For example, in the illustrated embodiment, the SSB of the 502 synchronization signal configuration comprises a set of synchronization signals including a PSS followed by an SSS and an RS (e.g., MRS), which in turn Petition 870240084234, dated 02 / 10 / 2024, pp. 38 / 63 34 / 51 is followed by two PBCH signals. It should be noted that although the 502 sync signal configuration begins with a PSS in the illustrated example, in some other embodiments, the SSB of the 502 sync signal configuration may begin with any other types of sync signals, such as an SSS, RS, PBCH, or similar. Furthermore, it should be noted that in some other embodiments, the SSB of the 502 sync signal configuration may comprise a set of sync signals including any combination of any number of sync signals in any suitable order.

[00061] In order to adjust the same synchronization signal configuration 502 to the data units 526, the SSB of the synchronization signal configuration 502 can be placed in different locations relative to the start of the communication blocks 520-2, 520-4, 520-6, 520-8 in different communication modes 510-2, 510-4 and 510-6. In some wireless communication systems, the synchronization signals are first detected, and then the boundary of a communication block (i.e., the start of the communication block) containing the synchronization signals is then determined relative to the position of the synchronization signals. Therefore, a mechanism here that clearly indicates the boundary of a communication block in different communication modes can provide efficient processing and reduce computational complexity in the system.

[00062] A boundary identification technique according to some forms of description implementation provides Petition 870240084234, dated 02 / 10 / 2024, pp. 39 / 63 35 / 51 information (herein referred to as boundary information) indicating the relative distance between the communication block boundary and the start of the synchronization signals by means of at least one of the synchronization signals. In such a configuration, once a receiving node (e.g., UE) receives the communication block and detects the synchronization signals, the receiving node can extract the boundary information from the synchronization signals and then determine the communication block boundary.

[00063] In operation according to the embodiments, the distances 530-2, 530-4, 530-6 between the start of the communication blocks 520-2, 520-4, 520-6 and the start of the SSB of the synchronization signal configuration 502 can be predetermined for each of the communication modes. The communication mode of a communication block can be indicated in the boundary information included in at least one of the synchronization signals of the SSB of the synchronization signal configuration 502 (for example, one or more of PSS, SSS, RS and PBCH) according to the embodiments of the present description.For example, in the illustrated example, the distance 530-2 represents that the start of the 520-2 communication block is three units (e.g., symbols) from the start of the SSB of the synchronization signal configuration 502 for communication mode 510-2. The distance 530-4 represents that the start of the 520-4 communication block is five units (e.g., symbols) from the start of the SSB of the synchronization signal configuration 502 for communication mode 5104, and the distance 530-6 represents that the start of the 520-6 communication block is two units (e.g., symbols). Petition 870240084234, dated 02 / 10 / 2024, pp. 40 / 63 36 / 51 from the start of the SSB of the 502 synchronization signal configuration for the 510-6 communication mode. According to the embodiments described, the preceding distances between the start of a communication block and the start of an SSB (e.g., 3 units for 510-2 communication mode, 5 units for 510-4 communication mode, and 2 units for 510-6 communication mode) are predetermined, and thus can be known a priori by the various nodes of the network (e.g., gNB, UE, etc.). Thus, when a receiver detects a 502 synchronization signal configuration SSB in a received communication block and determines from the control information included in one or more of the synchronization signals that the communication mode in use is 510-2 communication mode, then the receiver can determine that the communication block starts three units before the start of the 502 synchronization signal configuration SSB (which is the start of the PSS in the illustrated example).Alternatively, when a receiver detects the 502 synchronization signal setting in a received communication block and determines from the control information included in one or more synchronization signals that the communication mode used is 510-4 communication mode, the receiver can determine that the communication block starts five units before the start of the 502 synchronization signal setting SSB.

[00064] Alternatively, the distances 530-2, The intervals between the start of communication blocks 5202, 520-4, 520-6 and the start of a synchronization signal configuration SSB 502 may not be predetermined for each communication mode, such as in forms of Petition 870240084234, dated 02 / 10 / 2024, page 41 / 63 37 / 51 implementation where flexibility in placing a 502 synchronization signal configuration SSB at any position in a communication block is supported. The 530-2, 530-4, 530-6 distance values ​​relative to the different communication modes can be indicated in the boundary information included in at least one of the synchronization signals of a 502 synchronization signal configuration SSB (e.g., one or more of PBCH, PSS, SSS, and RS). As the 530-2, 530-4, 530-6 distances are not predetermined for each communication mode, this solution has the advantage of flexibly placing a 502 synchronization signal configuration SSB at any position in a communication block.For example, in one embodiment, the start of a 502 synchronization signal configuration SSB may be placed six units after the start of a communication block, and such relative distance is indicated by boundary information included in one or more of the synchronization signals (e.g., a PBCH signal) of the SSB. Once a receiving node receives the communication block, it can determine the start of the communication block by detecting the start of the 502 synchronization signal configuration SSB and extracting the boundary information comprising the aforementioned distance information from the PBCH signal.

[00065] In operation according to the embodiments, a receiving node can determine the communication mode (e.g., communication mode 510-2, communication mode 510-4, or communication mode 510-6) in use in relation to a communication block using SSB numerology (e.g., frequency-dependent). Petition 870240084234, dated 02 / 10 / 2024, pp. 42 / 63 38 / 51 carrier). It should be noted that, in the above scenario, the communication mode in use does not need to be indicated in one of the synchronization signals. However, embodiments may nevertheless indicate the communication mode of a communication block in the boundary information included in at least one of the synchronization signals of the 502 synchronization signal configuration. For example, boundary information may be derived for each communication mode by means of the SSB index, where the SSB index may be determined by the contents of RS and PBCH, for example.

[00066] Figure 6 shows a block diagram for method 600 indicating a communication block boundary containing a unified synchronization signal arrangement.In the illustrated embodiment, in block 602 the unified synchronization signal logic (e.g., an instruction set stored by memory 242 and executable in the gNB 105 controller / processor 240) of a network node determines a multiple synchronization signal arrangement for wireless communication between two or more nodes, wherein the multiple synchronization signal arrangement is configured for multiple communication modes (e.g., includes a particular synchronization signal arrangement, with or without one or more spaces, and a relative distance between the start of communication blocks of each plurality of communication modes and the start of the synchronization signal arrangement to accommodate the synchronization signal arrangement in the communication blocks of each of the plurality of communication modes). Each communication mode of the multiple communication modes may, for example, operate using subcarrier spacing. Petition 870240084234, dated 02 / 10 / 2024, pp. 43 / 63 39 / 51 different. The nodes may include a gNB, a UE and / or other devices in the 100 wireless communications network as described above in relation to Figure 1. The unified synchronization signal arrangement may include 302, 502 synchronization signal configurations providing SSBs as described above in Figures 3 and 5 or any other configurations appropriate for use in relation to the multiple communication modes to be accommodated. The synchronization signals in SSBs of the synchronization signal arrangement may include one or more of the following signals: PSS, SSS, RS and / or PBCH signals.

[00067] In operation according to the embodiments, in block 604 the unified synchronization signal logic causes a relative distance between a start of the multi-signal synchronization array and a start of a communication block containing the multi-signal synchronization array to be indicated by at least one synchronization signal of the multi-signal synchronization array. For example, a set of instructions stored by memory 242 and executable in the gNB 105 controller / processor 240 can control the transmission processor 220 in inserting boundary information indicating the relative distance in one or more synchronization signals (e.g., PSS, SSS, RS, and / or PBCH signals) of the synchronization signal array.In operation according to an exemplary embodiment, RS and PBCH together with SSB numerology can be used to carry boundary information, such as to allow boundary information for each communication mode to be derived via SSB index. Petition 870240084234, dated 02 / 10 / 2024, pp. 44 / 63 40 / 51 where the SSB index is determined by the RS and PBCH contents.

[00068] In some embodiments, the relative distances (e.g., distances 530-2, 530-4, 530-6 described in Figure 5 or similar distances as those present in the configuration of Figure 3) can be predetermined for each communication mode (e.g., communication modes 520-2, 510-4, 510-6 described above in connection with Figure 5 or similar communication modes as those present in the configuration of Figure 3). Consequently, the boundary information embedded in one or more synchronization signals can indicate the communication mode in use, whereby the receiving node can derive the relative distance from the communication mode information and knowledge of the corresponding predetermined relative distance.For example, the unified synchronization signal logic (e.g., an instruction set stored by memory 242 and executable in the controller / processor 240 of gNB 105) can determine the communication mode being used in relation to a communication (e.g., one of the communication modes 510-2, 510-4, or 510-6 or similar communication modes as are present in the configuration of Figure 3) and control a transmission signal processor (e.g., transmission processor 220 of gNB 105) to insert boundary information indicating that particular communication mode into one or more synchronization signals of the synchronization signal arrangement. In operation according to an exemplary embodiment, the contents of RS and PBCH can be provided with information from which the SSB index can be determined by a receiving node. Petition 870240084234, dated 02 / 10 / 2024, pp. 45 / 63 41 / 51 that the SSB index and SSB numerology indicate the communication mode in use. Correspondingly, the unified synchronization signal logic can control the transmission signal processor to include the synchronization signal arrangement within a communication block (e.g., a frame) with the appropriate relative distance between a start of the synchronization signal arrangement and a start of the communication block.For example, the unified synchronization signal logic can access one or more databases (e.g., a relative distance lookup table of the unified synchronization signal communication mode stored by gNB 105 memory 242 providing a knowledge base regarding the relative distance from the start of the synchronization signal arrangement and the start of a communication block containing the synchronization signal arrangement for each of the various accommodated communication modes) to determine an appropriate relative distance (e.g., distances 530-2, 530-4, 530-6 described in Figure 5 or similar distances as present in the configuration of Figure 3) for the synchronization signal arrangement for the communication mode to be used, and then provide the appropriate control to implement the relative distance by arranging the synchronization signals of the synchronization signal arrangement in the communication block.

[00069] In some embodiments, the relative distance (e.g., distances 530-2, 530-4, 530-6 described in Figure 5 or similar distances as present in the configuration of Figure 3) is not predetermined. Consequently, the boundary information Petition 870240084234, dated 02 / 10 / 2024, pp. 46 / 63 42 / 51 inserted in one or more synchronization signals can indicate the relative distance value. For example, the unified synchronization signal logic (e.g., an instruction set stored by memory 242 and executable on the gNB 105 controller / processor 240) can determine the communication mode being used in relation to a communication (e.g., one of the 510-2, 510-4, or 510-6 communication modes, or similar communication modes as those present in the configuration of Figure 3) and derives the corresponding relative distance value (e.g., distances 530-2, 530-4, 530-6 described in Figure 5, or similar distances as those present in the configuration of Figure 3) for that particular communication mode from the synchronization signal arrangement determined in block 602.Therefore, the unified synchronization signal logic can control a transmission signal processor (e.g., gNB 105 transmission processor 220) to insert boundary information indicating the particular relative distance in one or more synchronization signals of the synchronization signal array. In operation according to an exemplary embodiment, the RS and PBCH can be used to carry boundary information, such as that indicating the relative distance. Correspondingly, the unified synchronization signal logic can control the transmission signal processor to include the synchronization signal array within a communication block (e.g., a frame) with the appropriate relative distance between a start of the synchronization signal array and a... Petition 870240084234, dated 02 / 10 / 2024, pp. 47 / 63 43 / 51 start of the communication block, as previously determined.

[00070] Figure 7 shows a block diagram for method 700 to determine a boundary of a communication block containing a unified synchronization signal array. In the illustrated embodiment, in block 702 the unified synchronization signal logic (e.g., an instruction set stored by memory 282 and executable on the UE 115 controller / processor 280) of a network node monitors one or more channels for synchronization signals (e.g., PSS, SSS, RS, and / or PBCH signals) of a multi-synchronization signal array to detect the presence of the synchronization signal array in a transmission.For example, a receiving processor (e.g., receiving processor 258) can process and analyze received signals to detect one or more synchronization signals, whereby the receiving processor provides information regarding the detected synchronization signals to a controller (e.g., controller / processor 280) of the receiving node to determine if a particular arrangement of multiple synchronization signals is present in the received signals (e.g., a synchronization signal arrangement is carried in a received communication block).

[00071] In operation according to the embodiments, in block 704, where the synchronization signal arrangement is determined to be present in the received signals, the unified synchronization signal logic determines a relative distance between the start of the multiple synchronization signal arrangement and the start of a Petition 870240084234, dated 02 / 10 / 2024, pp. 48 / 63 44 / 51 communication block containing the array of multiple synchronization signals to be indicated by at least one synchronization signal from the multiple synchronization signal array. For example, a set of instructions stored by memory 282 and executable in the UE 115 controller / processor 280 can control the receiving processor 258 to extract boundary information indicating the relative distance of one or more synchronization signals (e.g., PSS, SSS, RS, and / or PBCH signals) from the synchronization signal array and provide the boundary information to the controller / processor 280. The unified synchronization signal logic can use the boundary information extracted from one or more synchronization signals to determine the relative distance between the start of the detected synchronization signal array and the start of a communication block in which the synchronization signal array was received.

[00072] In some embodiments, relative distances (e.g., distances 530-2, 530-4, 530-6 described in Figure 5 or similar distances as present in the configuration of Figure 3) can be predetermined for each communication mode (e.g., communication modes 520-2, 510-4, 510-6 described above in connection with Figure 5 or similar communication modes as present in the configuration of Figure 3). Consequently, boundary information extracted from one or more synchronization signals can indicate the communication mode in use, from which the receiving node can derive the relative distance from the communication mode information and knowledge of the predetermined relative distance. Petition 870240084234, dated 02 / 10 / 2024, pp. 49 / 63 45 / 51 corresponding. For example, the unified synchronization signal logic (e.g., an instruction set stored by memory 282 and executable on the UE 115 controller / processor 280) can analyze the extracted boundary information to determine the communication mode being used in relation to a received communication block (e.g., one of the 510-2, 510-4, or 510-6 communication modes or similar communication modes as present in the configuration of Figure 3) and access to one or more databases (e.g., a relative distance unified synchronization signal communication mode searches the table stored by memory 282 of the UE 115,Providing a knowledge base regarding the relative distance from the start of the synchronization signal array and the start of a communication block containing the synchronization signal array for each of the plurality of accommodated communication modes) to determine the relative distance (e.g., distances 530-2, 530-4, 530-6 described in Figure 5 or similar distances as present in the configuration of Figure 3) from the start of the detected synchronization signal array and the start of the communication block for the communication mode being used. Consequently, the unified synchronization signal logic can provide the appropriate control to use the relative distance information to detect the start of the communication block, as well as to extract data from it.

[00073] In some embodiments, the relative distance (e.g., distances 530-2, 530-4, Petition 870240084234, dated 02 / 10 / 2024, pp. 50 / 63 46 / 51 The distances described in Figure 5 (or similar distances as shown in Figure 3) are not predetermined. Consequently, boundary information extracted from one or more synchronization signals can indicate the relative distance value. The unified synchronization signal logic (e.g., an instruction set stored in memory 282 and executable on the UE 115 controller / processor 280) can thus obtain the relative distance between the start of the synchronization signal arrangement and the start of the communication block directly from boundary information extracted from one or more synchronization signals by the receiving processor (e.g., receiving processor 258). Therefore, the unified synchronization signal logic can provide appropriate control to use the relative distance information to detect the start of the communication block, as well as to extract data from it.
