Description

[0001] Cross-reference to related applications

[0002] This patent application claims priority to pending U.S. nonprovisional application No. 18 / 326,601, filed May 31, 2023, which has been assigned to the assignee of this application and is expressly incorporated herein by reference, as fully set forth below and for all applicable purposes. Technical Field

[0003] This disclosure relates in general to wireless communication, and more specifically to the design of a master synchronization signal. Background Technology

[0004] SSBs transmitted in bursts within a Synchronization Signal Block (SSB) can be used in conjunction with channel measurements and handover decisions. In some examples, a wireless communication device may need to temporarily suspend communication with its serving cell to tune its receiver to a frequency used by a neighboring cell or adjacent transmit and receive point to receive and measure that adjacent SSB. In this example, the time during which the UE cannot communicate with its serving cell is called the measurement gap length. Configurations of SSB resources that result in overall inefficient use of time-frequency resources and unnecessarily long measurement gap lengths are undesirable. Summary of the Invention

[0005] The systems, methods, and apparatus disclosed herein each have some innovative aspects, but no single aspect is solely responsible for the desired properties disclosed herein.

[0006] In one example, a method at a network entity is described. The method includes: configuring SSBs using Synchronization Signal Block (SSB) resources, which transmit a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH) within an SSB resource area of ​​a time-frequency resource grid, defined temporally by a first configured integer number of time units and frequency-defined by a second configured integer number of physical channels. According to one aspect, the product of the first configured integer number and the second configured integer number is a predetermined constant value, each symbol of the SSB has an equal number of Resource Elements (REs), and all REs in each symbol of the SSB have non-zero values, except for REs within a first frequency guard band between any two of the PSS, the SSS, and the PBCH in each symbol of the SSB. The method also includes: transmitting the SSB in the SSB resources as a beamformed SSB.

[0007] In one example, a network entity is described. This network entity includes one or more memories and one or more processors. The one or more processors are individually or collectively configured, at least in part, based on information stored in the one or more memories, to: configure SSBs using Synchronization Signal Block (SSB) resources, which transmit a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH) within an SSB resource area of ​​a time-frequency resource grid, defined temporally by an integer number of time units of a first configuration and frequency-defined by an integer number of physical channels of a second configuration. In some aspects, the product of the first and second configuration integer numbers is a predetermined constant value, each symbol of the SSB has an equal number of Resource Elements (REs), and all REs in each symbol of the SSB have non-zero values, except for REs within a first frequency guard band between any two of the PSS, SSS, and PBCH in each symbol of the SSB. The one or more processors are also individually or collectively configured to transmit the SSB in the SSB resource as a beamforming SSB, based at least in part on information stored in the one or more memories.

[0008] In one example, a method at a user equipment is described. According to this example, the method includes: receiving a synchronization signal block (SSB) from a network entity, the SSB transmitting a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH) within an SSB resource area of ​​a time-frequency resource grid, defined temporally by a first configured integer number of time units and frequency-defined by a second configured integer number of physical channels. In some aspects, the product of the first configured integer number and the second configured integer number is a predetermined constant value, each symbol of the SSB has an equal number of resource elements (REs), and all REs in each symbol of the SSB have non-zero values, except for REs within a first frequency guard band between any two of the PSS, the SSS, and the PBCH in each symbol of the SSB. The method further includes: sending to the network entity at least one of the following: a Layer 1 (L1) measurement report or a Layer 3 (L3) measurement report based on measurements of the SSB reference signal (SSB-RS) within the SSB resource area.

[0009] In another example, a user equipment is described. In this example, the user equipment includes one or more memories and one or more processors. According to some aspects, the one or more processors are individually or jointly configured to receive synchronization signal blocks (SSBs) from a network entity based at least in part on information stored in the one or more memories. The synchronization signal blocks (SSBs) transmit a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH) within an SSB resource area of ​​a time-frequency resource grid, defined temporally by an integer number of time units of a first configuration and frequency-defined by an integer number of physical channels of a second configuration. According to some aspects, the product of the first and second configured integer numbers is a predetermined constant value, each symbol of the SSB has an equal number of resource elements (REs), and all REs in each symbol of the SSB have non-zero values, except for REs within a first frequency guard band between any two of the PSS, the SSS, and the PBCH in each symbol of the SSB. According to some aspects, the one or more processors are also configured individually or collectively to, at least in part, send to the network entity, based on information stored in the one or more memories, at least one of the following: a Layer 1 (L1) measurement report or a Layer 3 (L3) measurement report based on measurements of SSB reference signals (SSB-RS) within the SSB resource area.

[0032] For the purpose of describing the innovative aspects of this disclosure, the detailed description set forth below in conjunction with the accompanying drawings relates to certain specific examples. However, those skilled in the art will readily recognize that the teachings herein can be applied in a variety of different ways. Some or all of the examples described may be applicable to Bluetooth systems that meet the requirements of the Institute of Electrical and Electronics Engineers (IEEE) 802.11, IEEE 802.15, or Bluetooth as defined by the Bluetooth Special Interest Group (SIG). ® The described examples can be implemented in any device, system, or network that transmits and receives radio frequency (RF) signals using one or more of the following standards or those published by the 3rd Generation Partnership Project (3GPP): Long Term Evolution (LTE), 3G, 4G, or 5G (New Radio (NR)).

The examples described can also be implemented using other wireless communication protocols or RF signals suitable for use in one or more of the following wireless personal area networks (WPAN), wireless local area networks (WLAN), wireless wide area networks (WWAN), wireless metropolitan area networks (WMAN), or Internet of Things (IoT) networks.

[0033] The detailed description below, illustrated with reference to the accompanying drawings, is intended as a description of various configurations and not as representing only the configurations in which the concepts described herein can be practiced. To provide a thorough understanding of the various concepts, the detailed description includes specific details. However, it will be apparent to those skilled in the art that these concepts can be practiced without these specific details. In some examples, well-known structures and components are shown in block diagram form to avoid obscuring such concepts.

[0034] While aspects and examples are described herein by way of illustration, 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 across many different platform types, devices, systems, shapes, sizes, and package arrangements. For example, aspects and / or uses may arise via integrated chip examples and other devices based on non-modular components (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail / shopping devices, medical devices, AI-enabled devices, etc.). While some examples may or may not specifically point to a use case or application, various applicability to the described innovations is possible. Implementations may range from chip-level or modular components to non-modular, non-chip-level implementations, and further to aggregated, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more aspects of the described innovations. In some practical settings, devices incorporating the described aspects and features may also necessarily include additional components and features for the implementation and execution of the claimed and described examples. For example, the transmission and reception of wireless signals necessarily involve multiple components (e.g., hardware components including antennas, radio frequency (RF) chains, power amplifiers, modulators, buffers, processors, interleavers, adders / summers, etc.) for analog and digital purposes. The innovations described herein are intended to be implemented in a wide variety of devices, chip-level components, systems, distributed arrangements, disassembled arrangements (e.g., base stations and / or user equipment (UE)), end-user equipment, etc., of different sizes, shapes, and constructions.

[0035] This document describes techniques associated with the configuration of Synchronization Signal Blocks (SSBs). An SSB includes SSB resources for transmitting a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH). According to some aspects of this disclosure, an SSB can be located within an SSB resource area of ​​a time-frequency resource grid, defined temporally by a first configured integer number of time units and frequency-defined by a second configured integer number of physical channels. According to some aspects of this disclosure, the product of the first configured integer number and the second configured integer number is a predetermined constant value, each symbol of the SSB has an equal number of Resource Elements (REs), and all REs in each symbol of the SSB have non-zero values, except for REs within a first frequency guard band between any two of the PSS, SSS, and PBCH in each symbol of the SSB. Various aspects of PSS sequence generation are described according to some aspects of this disclosure.

[0036] The various concepts presented in this disclosure can be implemented across a wide variety of telecommunications systems, network architectures, and communication standards. Reference is now made to... Figure 1 The schematic diagram of an example of a wireless communication system 100 according to some aspects of this disclosure is presented as an illustrative example and not a limitation. The wireless communication system 100 includes three interaction domains: a core network 102, a radio access network (RAN) 104, and a user equipment (UE) 106. With the aid of the wireless communication system 100, the UE 106 (also referred to herein as a wireless communication device) is able to perform data communication with an external data network 110 (such as, but not limited to, the Internet).

[0037] RAN 104 can implement any suitable one or more wireless communication technologies to provide radio access to UE 106. As an example, RAN 104 can operate according to the 3rd Generation Partnership Project (3GPP) New Radio (NR) specification (commonly referred to as 5G). Alternatively, RAN 104 can operate according to a hybrid of 5G NR and the Evolved Universal Terrestrial Radio Access Network (eUTRAN) standard, commonly referred to as Long Term Evolution (LTE). 3GPP refers to such a hybrid RAN as Next Generation RAN or NG-RAN. Of course, many other examples can be utilized within the scope of this disclosure.

[0038] As illustrated in the figure, RAN 104 includes multiple network entities 108. Broadly speaking, network entities can be implemented in aggregated or monolithic base station architectures, or in decomposed base station architectures, and may include one or more of a central unit (CU), distributed unit (DU), radio unit (RU), near real-time (near RT) RAN intelligent controller (RIC), or non-real-time (non-RT) RIC. In some examples, a network entity may be a network element in the radio access network responsible for radio transmissions to and from the UE in one or more cells. In different technologies, standards, or contexts, network entities may be referred to by those skilled in the art as transceiver base station (BTS), radio base station, base station, radio transceiver, transceiver function, basic service set (BSS), extended service set (ESS), access point (AP), node B (NB), eNode B (eNB), gNode B (gNB), transmit and receive point (TRP), scheduling entity, network entity, or some other suitable term. In some examples, a network entity may include two or more TRPs that may be co-located or non-co-located. Each TRP can communicate on the same or different carrier frequencies within the same or different frequency bands. In the example where RAN 104 operates according to both LTE and 5G NR standards, one network entity can be an LTE network entity, while the other network entity can be a 5G NR network entity.

[0039] RAN 104 is also exemplified as supporting wireless communication for multiple mobile devices. In 3GPP standards, a mobile device may be referred to as a User Equipment (UE), but those skilled in the art may also refer to it as a Mobile Station (MS), Subscriber Station, Mobile Unit, Subscriber Unit, Radio Unit, Remote Unit, Mobile Device, Radio Equipment, Wireless Communication Equipment, Remote Equipment, Mobile Subscriber Station, Access Terminal (AT), Mobile Terminal, Radio Terminal, Remote Terminal, Handset, Terminal, User Agent, Mobile Client, Client, Scheduled Entity, or some other suitable term. UE 106 may be an apparatus (e.g., a mobile device, wireless communication equipment) that provides access to network services to a user.

[0040] Within this disclosure, a "mobile" device does not necessarily need to be mobile, and it may be stationary. The term mobile device or mobile equipment refers to a wide variety of devices and technologies. A UE may include multiple hardware structural components of a size, shape, and arrangement that facilitate communication; such components may include antennas, antenna arrays, RF chains, amplifiers, one or more processors, etc., electrically coupled to each other. For example, some non-limiting examples of mobile devices include mobile devices, cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal computers (PCs), notebooks, netbooks, smartbooks, tablets, personal digital assistants (PDAs), and a wide variety of embedded systems, such as those corresponding to the "Internet of Things" (IoT).

[0041] Mobile devices can be attached to automobiles or other transportation vehicles, remote sensors or actuators, robots or robotic equipment, satellite radios, Global Positioning System (GPS) devices, object tracking devices, drones, multi-rotor aircraft, quadcopters, remote control devices, consumer and / or wearable devices (such as glasses, wearable cameras, virtual reality devices, smartwatches, health or fitness trackers), digital audio players (e.g., MP3 players), cameras, game consoles, etc. Mobile devices can also be attached to digital home or smart home devices (such as home audio, video, and / or multimedia devices), appliances, vending machines, smart lighting fixtures, home security systems, smart meters, etc. Mobile devices can also be attached to smart energy devices, security devices, solar panels or solar arrays, municipal infrastructure equipment for controlling electrical power (e.g., smart grids), lighting, water supply, etc., industrial automation and enterprise equipment, logistics controllers and / or agricultural equipment, etc. Furthermore, mobile devices can provide connected medical or telemedicine support, such as healthcare at a distance. Telemedicine devices may include telemedicine monitoring devices and telemedicine management devices, whose communications may be given priority or priority over other types of information access, for example, in terms of priority access for the transmission of critical service data and / or in terms of relevant QoS for the transmission of critical service data.

[0042] Wireless communication between RAN 104 and UE 106 can be described as utilizing an air interface. Transmissions via the air interface from a network entity (e.g., similar to network entity 108) to one or more UEs (e.g., similar to UE 106) can be referred to as downlink (DL) transmissions. According to certain aspects of this disclosure, the term downlink can refer to point-to-multipoint or point-to-point transmissions (e.g., multicast, multicast, or unicast) originating at a network entity (e.g., network entity 108). Another way to describe this scheme is to use the term "broadcast channel multiplexing." Transmissions from a UE (e.g., UE 106) to a network entity (e.g., network entity 108) can be referred to as uplink (UL) transmissions. According to a further aspect of this disclosure, the term "uplink" can refer to point-to-point transmissions originating at a UE (e.g., UE 106).

[0043] In some examples, access to the air interface can be scheduled, where a network entity (e.g., network entity 108) allocates resources for communication among some or all devices and equipment within its service area or cell. Within this disclosure, as further discussed below, the network entity (e.g., network entity 108) may be responsible for scheduling, assigning, reconfiguring, and releasing resources for one or more scheduled entities (e.g., UE 106). That is, for scheduled communication, multiple UEs 106 (which may be scheduled entities) may utilize the resources allocated by network entity 108.

[0044] Network entity 108 is not the only entity that can act as a scheduling entity. That is, in some examples, a UE can act as a scheduling entity, scheduling resources for one or more scheduled entities (e.g., one or more other UEs). For example, a UE can communicate directly with other UEs in a peer-to-peer or device-to-device manner and / or in a relay configuration.

[0045] like Figure 1As illustrated, network entity 108 may broadcast downlink service 112 (also referred to as downlink data service) to one or more UEs 106. Broadly speaking, network entity 108 may be a node or device responsible for scheduling services (e.g., data services, user data services) in a wireless communication network, including downlink service 112 and, in some examples, uplink service 116 (also referred to as uplink data service) from one or more UEs 106 to network entity 108. On the other hand, UE 106 (e.g., the scheduled entity) may be a node or device receiving downlink control 114 information (including, but not limited to, scheduling information (e.g., granting), synchronization or timing information, or other control information) from another entity in the wireless communication network (such as network entity 108). UE 106 may further send uplink control 118 information to network entity 108, including but not limited to scheduling requests or feedback information or other control information.

[0046] Furthermore, uplink control information 118 and / or downlink control information 114 and / or uplink traffic 116 and / or downlink traffic 112 can be transmitted on a waveform that can be time-divided into frames, subframes, time slots, and / or symbols. As used herein, a symbol can refer to a time unit in an Orthogonal Frequency Division Multiplexing (OFDM) waveform that carries one resource element (RE) per subcarrier. A time slot can carry 7 or 14 OFDM symbols. A subframe can refer to a duration of 1 ms. Multiple subframes or time slots can be grouped together to form a single frame or radio frame. Within this disclosure, a frame can refer to a predetermined duration (e.g., 10 ms) for wireless transmission, where each frame consists, for example, of 10 subframes, each 1 ms in length. Of course, these definitions are not mandatory, and any suitable scheme for organizing the waveform can be utilized, and various time divisions of the waveform can have any suitable duration.

[0047] Generally, network entity 108 may include a backhaul interface (not shown) for communicating with the backhaul section 120 of the wireless communication system 100. The backhaul section 120 provides a link between network entity 108 and the core network 102. Furthermore, in some examples, the backhaul network provides interconnection between the respective network entities 108. Various types of backhaul interfaces can be employed, such as a direct physical connection using any suitable transport network, a virtual network, etc.

[0048] Core network 102 may be part of wireless communication system 100 and may be independent of the radio access technology used in RAN 104. In some examples, core network 102 may be configured according to 5G standards (e.g., 5G core (5GC)). In other examples, core network 102 may be configured according to 4G evolved packet core (EPC) or any other suitable standard or configuration.

[0049] Now for reference Figure 2 The schematic diagram of an example radio access network (RAN) 200 according to some aspects of this disclosure is provided as an illustrative example and not a limitation. In some examples, the RAN 200 may be compatible with those described above and in... Figure 1 The same as RAN 104 shown in the example.

[0050] The geographical area covered by RAN 200 can be divided into several cellular areas (cells), and user equipment (UE) can uniquely identify these cellular areas (cells) based on an identifier broadcast from an access point or network entity within the geographical area. Figure 2 Cells 202, 204, 206, and 208 are illustrated, each of which may include one or more sectors (not shown). A sector is a sub-area of ​​a cell. All sectors within a cell are served by the same network entity. Radio links within a sector can be identified by a single logical identifier belonging to that sector. In a cell divided into sectors, multiple sectors within the cell can be formed by antenna groups, where each antenna is responsible for communicating with a UE within a portion of the cell.

[0051] It can be deployed using various network entities. For example, in Figure 2 In this example, two network entities (referred to as base station 210 and base station 212) are shown in cells 202 and 204. A third network entity (referred to as base station 214) is shown as a remote radio head (RRH) 216 controlling cell 206. That is, the network entity may have an integrated antenna, or may be connected to the antenna or RRH 216 by a feed cable. In the illustrated example, cells 202, 204, and 206 may be referred to as macro cells because base stations 210, 212, and 214 support cells with large sizes. Furthermore, base station 218 is shown in cell 208, which may overlap with one or more macro cells. In this example, cell 208 may be referred to as a small cell (e.g., small cell, microcell, picocell, femtocell, home base station, home node B, home eNode B, etc.) because base station 218 supports cells with relatively small sizes. Cell size settings can be made according to system design and component constraints.

[0052] It should be understood that RAN 200 may include any number of network entities (e.g., base stations, gNBs, TRPs, scheduling entities) and cells. Furthermore, relay nodes may be deployed to extend the size or coverage area of ​​a given cell. Base stations 210, 212, 214, and 218 provide radio access points to the core network for any number of mobile devices. In some examples, base stations 210, 212, 214, and / or 218 may be used in conjunction with those described above and... Figure 1The network entity 108 illustrated herein is the same as or similar to it.

[0053] Figure 2 It also includes an unmanned aerial vehicle (UAV) 220, which can be a drone, quadcopter, octocopter, etc. The UAV 220 can be configured to function as a base station, or more specifically, as a mobile base station. That is, in some examples, the cell does not necessarily need to be stationary, and the geographical area of ​​the cell can move depending on the location of the mobile base station (such as the UAV 220).

[0054] Within RAN 200, a cell may include UEs capable of communicating with one or more sectors of each cell. Furthermore, each base station 210, 212, 214, 218, and 220 may be configured to provide access to the core network 102 (see [link to core network]) to all UEs within the corresponding cell. Figure 1 Access points. For example, UEs 222 and 224 may communicate with base station 210, UEs 226 and 228 may communicate with base station 212, UEs 230 and 232 may communicate with base station 214 via RRH 216, UE 234 may communicate with base station 218, and UE 236 may communicate with mobile base station 220. In some examples, UEs 222, 224, 226, 228, 230, 232, 234, 236, 238, 240, and / or 242 may communicate with the access points described above and... Figure 1 One or more UEs 106 illustrated herein are identical or similar. In some examples, UAV 220 may be a mobile network entity and may be configured to act as a UE. For example, UAV 220 may operate within cell 202 by communicating with base station 210.

[0055] In another aspect of RAN 200, sidelink signaling can be used between UEs without relying on scheduling or control information from the base station. Sidelink communication can be utilized in device-to-device (D2D) networks, peer-to-peer (P2P) networks, vehicle-to-vehicle (V2V) networks, vehicle-to-everything (V2X) networks, and / or other suitable sidelink networks. For example, two or more UEs (e.g., UEs 238, 240, and 242) can communicate with each other using sidelink signal 237 without relaying the communication through a base station. In some examples, UEs 238, 240, and 242 can each act as a scheduling entity or transmitting sidelink device and / or a scheduled entity or receiving sidelink device to schedule resources and communicate sidelink signal 237 between them, without relying on scheduling or control information from a base station (e.g., a network entity). In other examples, two or more UEs (e.g., UEs 226 and 228) within the coverage area of ​​a network entity (e.g., base station 212) may also communicate sidelink signal 227 via a direct link (sidelink) without requiring the network entity (e.g., base station 212) to deliver the communication. In this example, base station 212 may allocate resources to UEs 226 and 228 for sidelink communication.

[0056] To achieve a low block error rate (BLER) while still maintaining a very high data rate during transmission over the air interface, channel decoding can be used. That is, wireless communication typically utilizes appropriate error-correcting block codes. In a typical block code, the information message or sequence is broken down into code blocks (CBs), and the encoder (e.g., codec) at the transmitting device then mathematically adds redundancy to the information message. Utilizing this redundancy in the encoded information message improves message reliability and corrects for any bit errors that may occur due to noise.

[0057] Data decoding can be implemented in several ways. In early 5G NR specifications, quasi-cyclic low-density parity-check (LDPC) was used to decode user data using two different base maps: one base map was used for large code blocks and / or high code rates, while the other base map was used for other cases. Polarity decoding was used to decode control information and the Physical Broadcast Channel (PBCH) based on nested sequences. For these channels, truncation, shortening, and repetition were used for rate matching.

[0058] Various aspects of this disclosure can be implemented using any suitable channel code. Specific implementations of network entities and UEs may include suitable hardware and capabilities (e.g., encoders, decoders, and / or codecs) to utilize one or more of these channel codes for wireless communication.

[0059] In RAN 200, the ability of a UE to communicate while moving (independent of its location) is referred to as mobility. Various physical channels between the UE and RAN 200 are generally established, maintained, and released under the control of the Access and Mobility Management Function (AMF). In some scenarios, the AMF may include a Security Context Management Function (SCMF) and a Security Anchor Function (SEAF) that performs authentication. The SCMF can manage the security context for both control plane and user plane functions, either wholly or partially.

[0060] In various aspects of this disclosure, RAN 200 can utilize DL-based mobility or UL-based mobility to achieve movement and handover (i.e., the UE's connection is transferred from one radio channel to another). In a network configured for DL-based mobility, during a call with a network entity (e.g., aggregated or decomposed base station, gNB, eNB, TRP, scheduling entity, etc.) or at any other time, the UE can monitor various parameters of the signal from its serving cell and various parameters of neighboring cells. Based on the quality of these parameters, the UE can maintain communication with one or more neighboring cells. During this time, if the UE moves from one cell to another, or if the signal quality from a neighboring cell exceeds the signal quality from the serving cell for a given amount of time, the UE can perform a handover or transfer from the serving cell to a neighboring (target) cell. For example, UE 224 can move from a geographic area corresponding to its serving cell (e.g., cell 202) to a geographic area corresponding to a neighboring cell (e.g., cell 206). When the signal strength or quality from a neighboring cell exceeds that of its serving cell for a given amount of time, UE 224 may send a report message indicating this condition to its serving network entity (e.g., base station 210). In response, UE 224 may receive a handover command, and UE may perform a handover to cell 206.

[0061] In a network configured for UL-based mobility, the network can select a serving cell for each UE using UL reference signals from each UE. In some examples, base stations 210, 212, and 214 / 216 can broadcast unified synchronization signals (e.g., unified primary synchronization signal (PSS), unified secondary synchronization signal (SSS), and unified physical broadcast channel (PBCH)). UEs 222, 224, 226, 228, 230, and 232 can receive unified synchronization signals, derive carrier frequencies and time slot timings from these synchronization signals, and transmit uplink pilots or reference signals in response to the derived timings. The uplink pilot signal transmitted by a UE (e.g., UE 224) can be received concurrently by two or more cells (e.g., base stations 210 and 214 / 216) within RAN 200. Each cell can measure the strength of the pilot signal, and the radio access network (e.g., one or more of the central nodes within base stations 210 and 214 / 216 and / or the core network) can determine the serving cell for UE 224. As UE 224 moves through RAN 200, RAN 200 can continue to monitor the uplink pilot signal transmitted by UE 224. When the signal strength or quality of the pilot signal measured by a neighboring cell exceeds the signal strength or quality measured by the serving cell, RAN 200 can hand over UE 224 from the serving cell to a neighboring cell, with or without notifying UE 224.

[0062] Although the synchronization signals transmitted by base stations 210, 212, and 214 / 216 can be uniform, these synchronization signals may not identify a specific cell, but rather a zone of multiple cells operating on the same frequency and / or using the same timing. Using zones in 5G networks or other next-generation communication networks enables an uplink-based mobility framework and improves the efficiency of both the UE and the network by reducing the number of mobility messages that need to be exchanged between the UE and the network.

[0063] In various specific implementations, the air interface in the radio access network 200 may utilize licensed spectrum, unlicensed spectrum, or shared spectrum. Licensed spectrum typically provides exclusive use of a portion of the spectrum by means of a license purchased from a government regulatory agency by a mobile network operator. Unlicensed spectrum provides shared use of a portion of the spectrum without requiring a government-granted license. While some technical rules are generally still required to access unlicensed spectrum, access is typically available to any operator or device. Shared spectrum falls between licensed and unlicensed spectrum, where access to the spectrum may require technical rules or restrictions, but the spectrum can still be shared by multiple operators and / or multiple radio access technologies (RATs). For example, a licensee of a portion of licensed spectrum may offer a Licensed Shared Access (LSA) to share the spectrum with other parties, for example, those with appropriate licensee-defined conditions for access.

[0064] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc., based on frequency / wavelength. In 5G NR, two initial operating bands have been designated as frequency ranges FR1 (410MHz-7.125GHz) and FR2 (24.25GHz-52.6GHz). It should be understood that although a portion of FR1 is greater than 6GHz, in various documents and articles, FR1 is often (interchangeably) referred to as the "sub-6GHz" band. Similar naming issues sometimes occur with FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although this is different from the Extremely High Frequency (EHF) band (30GHz-300GHz) designated as "millimeter wave" by the International Telecommunication Union (ITU).

[0065] The frequencies between FR1 and FR2 are generally referred to as intermediate frequency (IF) bands. Recent 5G NR studies have designated the operating bands for these IF bands as the frequency range designation FR3 (7.125GHz-24.25GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, thus effectively extending the features of FR1 and / or FR2 to IF band frequencies. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6GHz. For example, three higher operating bands have been designated as the frequency range designations FR4-a or FR4-1 (52.6GHz-71GHz), FR4 (52.6GHz-114.25GHz), and FR5 (114.25GHz-300GHz). Each of these higher frequency bands falls within the EHF band.

[0066] In light of the foregoing, unless otherwise specifically stated, it should be understood that, as used herein, the term "below 6 GHz" and the like can broadly refer to frequencies less than 6 GHz, within FR1, or including mid-band frequencies. Furthermore, unless otherwise specifically stated, it should be understood that, as used herein, the term "millimeter wave" and the like can broadly refer to frequencies within FR2, FR4, FR4-a, or FR4-1 and / or FR5, or within the EHF band.

[0067] Devices communicating in the radio access network 200 can utilize one or more multiplexing techniques and multiple access algorithms to achieve simultaneous communication between various devices. For example, the 5G NR specification provides multiple access for UL transmissions from UEs 222 and 224 to base station 210, and multiplexing for DL ​​transmissions from base station 210 to one or more UEs 222 and 224 using Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP). Furthermore, for UL transmissions, the 5G NR specification provides support for Discrete Fourier Transform Extended OFDM (DFT-s-OFDM) with CP (also known as Single-Carrier FDMA (SC-FDMA)). However, within the scope of this disclosure, multiplexing and multiple access are not limited to the above schemes and can be provided using Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Sparse Code Multiple Access (SCMA), Resource Extended Multiple Access (RSMA), or other suitable multiple access schemes. In addition, time division multiplexing (TDM), code division multiplexing (CDM), frequency division multiplexing (FDM), orthogonal frequency division multiplexing (OFDM), sparse code multiplexing (SCM) or other suitable multiplexing schemes can be used to provide multiplexing of DL transmissions from base station 210 to UEs 222 and 224.

[0068] Devices in the radio access network 200 may also utilize one or more duplex algorithms. Duplex refers to a point-to-point communication link where two endpoints can communicate with each other in both directions. Full-duplex means that two endpoints can communicate with each other simultaneously. Half-duplex means that only one endpoint can transmit information to the other endpoint at a time. Half-duplex simulations often utilize Time Division Duplex (TDD) for wireless links. In TDD, transmissions in different directions on a given channel are separated from each other using time division multiplexing. That is, in some scenarios, the channel is dedicated to transmission in one direction, while at other times, the channel is dedicated to transmission in the other direction, where the direction can change very rapidly, for example, several times per time slot. In wireless links, full-duplex channels generally rely on physical isolation between the transmitter and receiver, as well as appropriate interference cancellation techniques. Full-duplex simulations are often implemented for wireless links using Frequency Division Duplex (FDD) or Space Division Duplex (SDD). In FDD, transmissions in different directions can operate at different carrier frequencies (e.g., within paired spectrum). In SDD, spatial division multiplexing (SDM) is used to separate transmissions in different directions on a given channel from each other. In other examples, full-duplex communication can be implemented in unpaired spectrum (e.g., within a single carrier bandwidth), where transmissions in different directions occur within different subbands of the carrier bandwidth. This type of full-duplex communication may be referred to herein as subband full-duplex (SBFD), also known as flexible duplex.

[0069] The deployment of communication systems (such as 5G New Radio (NR) systems) can involve various components or parts arranged in multiple ways. In a 5G NR system or network, network entities, network mobility elements, radio access network (RAN) nodes, core network entities, network elements, or network equipment (such as base stations (BS), or one or more units (or components) performing base station functions) can be implemented in aggregated or decomposed architectures. For example, BS (such as Node B (NB), evolved NB (eNB), NR BS, 5G NB, access point (AP), transmit / receive point (TRP), or cell, etc.) can be implemented as aggregated base stations (also known as standalone BS or monolithic BS) or decomposed base stations.

[0070] Aggregated base stations can be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node. Decentralized base stations can be configured to utilize a protocol stack that is physically or logically distributed across two or more units, such as one or more central or centralized units (CUs), one or more distributed units (DUs), or one or more radio units (RUs). In some aspects, the CU can be implemented within a RAN node, and one or more DUs can be co-located with the CU, or alternatively, can be geographically or virtually distributed across one or more other RAN nodes. DUs can be implemented to communicate with one or more RUs. Each of the CU, DU, and RU can also be implemented as a virtual unit, namely a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU).

[0071] Base station type operation or network design can take into account the aggregation characteristics of base station functionality. For example, decomposed base stations can be utilized in Integrated Access Backhaul (IAB) networks, Open Radio Access Networks (O-RAN (such as network configurations initiated by the O-RAN Alliance)), or Virtualized Radio Access Networks (vRAN, also known as Cloud Radio Access Networks (C-RAN)). Decomposition can include distributing functionality across two or more units in various physical locations, as well as virtually distributing the functionality of at least one unit, which enables flexibility in network design. The various units in a decomposed base station or decomposed RAN architecture can be configured for wired or wireless communication with at least one other unit.

[0072] Figure 3 This is a schematic diagram of an example disaggregated base station 300 architecture based on some aspects of this disclosure. The disaggregated base station 300 architecture may include one or more central units (CUs) 310, which may communicate directly with the core network 320 via a backhaul link, or indirectly with the core network 320 via one or more disaggregated base station units (such as a near real-time (near-RT) RAN intelligent controller (RIC) 325 via an E2 link, or a non-real-time (non-RT) RIC 315 associated with a Service Management and Orchestration (SMO) framework 305, or both). CUs 310 may communicate with one or more distributed units (DUs) 330 via a corresponding midhaul link (such as an F1 interface). DUs 330 may communicate with one or more radio units (RUs) 340 via a corresponding fronthaul link. RUs 340 may communicate with a corresponding UE 342 via one or more radio frequency (RF) access links. In some specific implementations, a UE 342 may be served simultaneously by multiple RUs 340. For example, a UE 342 may be combined with... Figure 1 and Figure 2 The UE or scheduled entity illustrated and described is the same as or similar to any of them.

[0073] Each of these units (i.e., CU 310, DU 330, RU 340, and near-RT RIC 325, non-RT RIC 315, and SMO frame 305) may include one or more interfaces, or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via wired or wireless transmission media. Each of the units, or an associated processor or controller providing instructions to the communication interfaces of these units, may be configured to communicate with one or more other units via transmission media. For example, these units may include wired interfaces configured to receive signals or transmit signals to one or more other units via wired transmission media. Additionally, these units may include wireless interfaces that may include receivers, transmitters, or transceivers (such as radio frequency (RF) transceivers) configured to receive signals or transmit signals to one or more other units via wireless transmission media, or both.

[0074] In some aspects, the CU 310 can host one or more higher-level control functions. Such control functions may include Radio Resource Control (RRC), Packet Data Convergence Protocol (PDCP), Serving Data Adaptation Protocol (SDAP), etc. Each control function can be implemented using an interface configured to signal to other control functions hosted by the CU 310. The CU 310 can be configured to handle user plane functionality (i.e., Central Unit-User Plane (CU-UP)), control plane functionality (i.e., Central Unit-Control Plane (CU-CP)), or a combination thereof. In some implementations, the CU 310 can be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units can communicate bidirectionally with the CU-CP units via an interface such as an E1 interface. The CU 310 can be implemented to communicate with the DU 330 for network control and signaling purposes, as needed.

[0075] DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RU 340s. In some aspects, DU 330 may at least partially host one or more of the Radio Link Control (RLC) layer, Medium Access Control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.) according to functional splits (such as those defined by the 3rd Generation Partnership Project (3GPP). In some aspects, DU 330 may further host one or more low PHY layers. Each layer (or module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by DU 330 or with control functions hosted by CU 310.

[0076] Lower-layer functionality can be implemented by one or more RU 340s. In some deployments, an RU340 controlled by a DU 330 may correspond to a logical node that hosts RF processing functions or low-PHY layer functions (such as performing Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, Physical Random Access Channel (PRACH) extraction and filtering, or both, at least in part based on functional decomposition (such as lower-layer functional decomposition). In this architecture, the RU 340 may be implemented to handle over-the-air (OTA) communications with one or more UE 342s. In some specific implementations, the real-time and non-real-time aspects of control plane and user plane communications with the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration enables the implementation of the DU 330 and CU 310 in a cloud-based RAN architecture (such as a vRAN architecture).

[0077] SMO framework 305 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, SMO framework 305 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, SMO framework 305 can be configured to interact with a cloud computing platform such as Open Cloud (O-Cloud) 390 to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface such as the O2 interface. Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, and near-RT RIC 325. In some implementations, SMO framework 305 can communicate with the hardware aspects of the 3G RAN (such as Open eNB (O-eNB) 311) via the O1 interface. Additionally, in some implementations, SMO framework 305 can communicate directly with one or more RU 340s via the O1 interface. SMO framework 305 may also include a non-RT RIC 315 configured to support the functionality of SMO framework 305.

[0078] The non-RT RIC 315 can be configured to include logical functions enabling non-real-time control and optimization of RAN elements and resources, including artificial intelligence / machine learning (AI / ML) workflows for model training and updates, or policy-based guidance for applications / features in the near-RT RIC 325. The non-RT RIC 315 can be coupled to or communicate with the near-RT RIC 325, such as via an A1 interface. The near-RT RIC 325 can be configured to include logical functions enabling near real-time control and optimization of RAN elements and resources via an interface, such as via an E2 interface, connecting one or more CU 310s, one or more DU 330s, or both, and O-eNBs to the near-RT RIC 325.

[0079] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 325 and may be received from non-network data sources or network functions at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns in performance and use AI / ML models to perform corrective actions via the SMO framework 305 (such as reconfiguration via O1) or by creating RAN management policies (such as A1 policies).

[0080] Reference Figure 4 The illustrated OFDM waveforms are used to illustrate various aspects of this disclosure. Those skilled in the art will understand that various aspects of this disclosure can be applied to SC-FDMA waveforms in substantially the same manner as described below. That is, while some examples of this disclosure may focus on OFDM links for clarity, it should be understood that the same principles can also be applied to SC-FDMA waveforms.

[0081] Now for reference Figure 4 An expanded view of exemplary subframe 402 is illustrated, showing the OFDM resource grid. However, those skilled in the art will readily understand that the physical (PHY) transmission structure for any particular application can vary from the example described herein depending on any number of factors. Here, time is in OFDM symbols in the horizontal direction; and frequency is in subcarriers of the carrier in the vertical direction.

[0082] Resource grid 404 can be used to schematically represent time-frequency resources for a given antenna port. That is, in a multiple-input multiple-output (MIMO) implementation with multiple available antenna ports, the corresponding multiple resource grids 404 may be used for communication. Resource grid 404 is divided into multiple resource elements (REs) 406. An RE (which is 1 subcarrier × 1 symbol) is the smallest discrete part of the time-frequency grid and contains a single complex value representing data from a physical channel or signal. Depending on the modulation used in a particular implementation, each RE may represent one or more information bits. In some examples, a block of REs may be referred to as a physical resource block (PRB), or more simply as a resource block (RB) 408, which contains any suitable number of consecutive subcarriers in the frequency domain. In one example, an RB may include 12 subcarriers (a number independent of the parameter set used). In some examples, depending on the parameter set, an RB may include any suitable number of consecutive OFDM symbols in the time domain.

[0083] A collection of contiguous or non-contiguous resource blocks may be referred to herein as a Resource Block Group (RBG), Subband, or Bandwidth Part (BWP). A collection of subbands or BWPs may span the entire bandwidth. Scheduling of downlink, uplink, or sidelink transmissions to a wireless communication device (e.g., a V2X device, a sidelink device, or other UE, collectively referred to below as UE) may involve scheduling one or more resource elements 406 within one or more subbands or bandwidth parts (BWPs). Therefore, a UE typically utilizes only a subset of resource grids 404. In some examples, an RB may be the smallest unit of resource that can be allocated to a UE. Therefore, the more RBs scheduled for a UE, and the higher the modulation scheme selected for the air interface, the higher the data rate for the UE. RBs may be scheduled by network entities (e.g., aggregated or decomposed base stations, gNBs, eNBs, TRPs, scheduling entities, etc.) or may be self-scheduled by the UE / sidelink device implementing D2D sidelink communication.

[0084] In this illustration, RB 408 is shown occupying less than the entire bandwidth of subframe 402, with some subcarriers illustrated above and below RB 408. In a given specific implementation, subframe 402 may have a bandwidth corresponding to any number of one or more RBs 408. Furthermore, in this illustration, RB 408 is shown occupying less than the entire duration of subframe 402, although this is only one possible example.

[0085] Each 1ms subframe 402 can be composed of one or more adjacent time slots. Figure 4 In the example shown, as an illustrative example, a subframe 402 includes four time slots 410. In some examples, time slots may be defined based on a specified number of OFDM symbols with a given cyclic prefix (CP) length. For example, a time slot may include 7 or 14 OFDM symbols with a nominal CP. Additional examples may include micro-time slots (sometimes referred to as shortened transmission time intervals (TTIs)) with shorter durations (e.g., one to three OFDM symbols). These micro-time slots or shortened transmission time intervals (TTIs) may, in some cases, be transmitted by occupying resources scheduled for ongoing time slot transmissions for the same UE or different UEs. Any number of resource blocks may be utilized within a subframe or time slot.

[0086] An expanded view of time slot 410 illustrates that time slot 410 includes a control region 412 and a data region 414. Generally, control region 412 may carry a control channel, and data region 414 may carry a data channel. In some examples, a Uu time slot (e.g., time slot 410) may contain full DL, full UL, or at least one DL portion and at least one UL portion. Figure 4The structures illustrated herein are merely exemplary in nature and different time-slot structures may be used, and different time-slot structures may include one or more of each of the control region and the data region.

[0087] Despite Figure 4 Not illustrated, but various REs 406 within RB 408 can be scheduled to carry one or more physical channels, including control channels, shared channels, data channels, etc. Other REs 406 within RB 408 may also carry pilot or reference signals. These pilot or reference signals allow the receiving device to perform channel estimation for the corresponding channels, enabling coherent demodulation / detection of the control and / or data channels within RB 408.

[0088] In some examples, time slot 410 can be used for broadcast, multicast, unicast, or unicast communication. For example, broadcast, multicast, or unicast communication can refer to point-to-multipoint transmission from one device (e.g., a network entity, UE, or other similar device) to other devices. Here, broadcast communication is delivered to all devices, while multicast or unicast communication is delivered to multiple intended receiving devices. Unicast communication can refer to point-to-point transmission from one device to a single other device.

[0089] In an example of cellular communication over a cellular carrier via the Uu interface, for DL ​​transmission, a network entity may allocate one or more REs 406 of time slot 410 (e.g., within control area 412) to one or more UEs (e.g., scheduled entities) to carry DL control information including one or more DL control channels (such as the Physical Downlink Control Channel (PDCCH)). The PDCCH carries downlink control information (DCI), including but not limited to power control commands (e.g., one or more open-loop power control parameters and / or one or more closed-loop power control parameters), scheduling information, and the allocation and / or assignment of REs for DL ​​and UL transmissions. The PDCCH may further carry Hybrid Automatic Repeat Request (HARQ) feedback transmission, such as acknowledgment (ACK) or negative acknowledgment (NACK). HARQ is a technique well known to those skilled in the art, where, for accuracy, any suitable integrity verification mechanism (such as checksum or cyclic redundancy check (CRC)) may be used to verify the integrity of packet transmission at the receiving side. If the integrity of the transmission is acknowledged, an ACK may be sent, and if not, a NACK may be sent. In response to NACK, the transmitting device can send HARQ retransmissions, which can achieve tracking merging, incremental redundancy, etc.

[0090] Network entities may further allocate one or more REs 406 in Uu timeslot 410 (e.g., in control area 412 or data area 414) to carry other DL signals, such as demodulation reference signals (DMRS); phase tracking reference signals (PT-RS); channel state information (CSI) reference signals (CSI-RS); and synchronization signal blocks (SSBs). SSBs can be broadcast in regular intervals based on periodicity (e.g., 4ms, 10ms, 20ms, 50ms, 80ms, or 160ms). SSBs include the primary synchronization signal (PSS), secondary synchronization signal (SSS), and physical broadcast control channel (PBCH). UEs can utilize PSS and SSS to achieve radio frame, subframe, timeslot, and symbol synchronization in the time domain, identify the center of the channel (system) bandwidth in the frequency domain, and identify the physical cell identity (PCI) of the cell.

[0091] The PBCH in the SSB may also include a Master Information Block (MIB) containing various system information and parameters for decoding the System Information Block (SIB). The SIB may be, for example, System Information Type 1 (SIB1), which may include various additional system information. Together, the MIB and SIB1 provide minimum system information (SI) for initial access. Examples of system information transmitted in the MIB may include, but are not limited to, subcarrier spacing (e.g., default downlink parameter set), system frame number, configuration of the PDCCH control resource set (CORESET) (e.g., PDCCH CORESET0), cell prohibition indicator, cell reselection indicator, grid offset, and search space for SIB1. Examples of residual minimum system information (RMSI) transmitted in SIB1 may include, but are not limited to, random access search space, paging search space, downlink configuration information, and uplink configuration information. Network entities may also transmit other system information (OSI).

[0092] In UL transmission, the UE (e.g., the scheduled entity) may utilize one or more REs 406 in Uu slot 410 to carry UL control information (UCI) to the scheduling entity, including one or more UL control channels such as the Physical Uplink Control Channel (PUCCH). UCI may include various packet types and categories, including pilots, reference signals, and information configured to enable or assist in decoding uplink data transmission. Examples of uplink reference signals may include sounding reference signals (SRS) and uplink DMRS. In some examples, UCI may include a scheduling request (SR), i.e., a request to the scheduling entity to schedule uplink transmission. In this document, in response to an SR transmitted on the UCI, the scheduling entity may transmit downlink control information (DCI), which may schedule resources for uplink packet transmission. UCI may also include HARQ feedback, channel state feedback (CSF) (such as CSI reports), measurement reports (e.g., Layer 1 (L1) measurement reports), or any other suitable UCI.

[0093] In addition to control information, one or more REs 406 in Uu time slot 410 (e.g., within data area 414) may also be allocated for data services. Such data services may be carried on one or more service channels, such as on the Physical Downlink Shared Channel (PDSCH) for DL ​​transmissions, or on the Physical Uplink Shared Channel (PUSCH) for UL transmissions. In some examples, one or more REs 406 within data area 414 may be configured to carry other signals, such as one or more SIBs and DMRS. In some examples, the PDSCH may carry multiple SIBs, not limited to SIB1 discussed above. For example, OSI may be provided in these SIBs (e.g., SIB2 and above).

[0094] In an example of sidelink communication via a sidelink carrier through the PC5 interface, the control area 412 of time slot 410 may include a Physical Sidelink Control Channel (PSCCH), which includes sidelink control information (SCI) transmitted by an initiating (transmitting) sidelink device (e.g., a Tx V2X device or other Tx UE) to a set of one or more other receiving sidelink devices (e.g., Rx V2X devices or other Rx UEs). The data area 414 of time slot 410 may include a Physical Sidelink Shared Channel (PSSCH), which includes sidelink data traffic transmitted by the initiating (transmitting) sidelink device within resources reserved on the sidelink carrier via the SCI. Further information may be transmitted via various REs 406 within time slot 410. For example, a sidelink MAC-CE may be transmitted in the data area 414 of time slot 410. Furthermore, HARQ feedback information can be transmitted from the receiving sidelink device to the transmitting sidelink device in the Physical Sidelink Feedback Channel (PSFCH) within time slot 410. Additionally, one or more reference signals, such as sidelink SSB, sidelink CSI-RS, sidelink SRS, and / or sidelink positioning reference signal (PRS), can be transmitted within time slot 410.

[0095] The physical channels described above are typically multiplexed and mapped to transport channels for processing at the Medium Access Control (MAC) layer. The transport channels carry blocks of information called transport blocks (TBs). Based on the modulation and decoding scheme (MCS) and the number of redundancies (RBs) in a given transmission, the transport block size (TBS) (which may correspond to the number of information bits, e.g., the quantity) can be a controlled parameter.

[0096] The above text combined Figures 1 to 4 The channels or carriers described are not necessarily all channels or carriers available between devices, and those skilled in the art will recognize that other channels or carriers, such as other service, control, and feedback channels, may be available in addition to the channels or carriers illustrated.

[0097] Figure 5 This is an example of a portion of the resource mapping of a Synchronization Signal Block (SSB) 500 in a slot 502, used in conjunction with the Uu reference point in 5G NR. A slot 502 comprises 14 symbols. The SSB 500 can be mapped to 4 consecutive symbols in the time domain and 240 subcarriers (i.e., 20 RBs) in the frequency domain. In one example, with the 14 symbols of the slot indexed as {0, 1, 2, …13}, the first symbol of the SSB block (i.e., PSS) could appear at {2, 8}, {2, 9}, or {4, 8}. Figure 5The example shows that the primary synchronization signal (PSS) 504 is transmitted in the first symbol (out of four consecutive symbols), and the secondary synchronization signal (SSS) 506 is transmitted in the third symbol (out of four consecutive symbols). The physical broadcast channel (PBCH) 508 is transmitted in the second and fourth symbols (out of four consecutive symbols) and the third symbol, thus surrounding SSS 506 in the frequency domain.

[0098] Within SSB 500, PSS 504 is time-division multiplexed with SSS 506 and PBCH 508 (TDM). PSS 504 in the first symbol is mapped to 127 consecutive REs (representations) in the frequency domain (out of 127 consecutive subcarriers (subcarriers 57 to 183). REs for subcarriers below PSS 504 (subcarriers 1 to 56) and above PSS 504 (subcarriers 184 to 240) may have zero values ​​(or null values). As used herein, "hereinafter" may refer to frequencies having values ​​less than (e.g., below) a given frequency (i.e., the frequency being compared), and "above" may refer to frequencies having values ​​greater than (e.g., above) a given frequency. SSS 506 in the third symbol is mapped to the same subcarriers (subcarriers 57 to 183) as PSS 504. The guard band for the eight subcarriers surrounds SSS 506 below (sub-bands 49 to 56) and above (sub-bands 185 to 192) the subcarriers of SSS 506 (i.e., the REs in the guard band have zero values). PBCH 508 occupies a total of 576 REs; 240 REs in the second symbol, 240 REs in the fourth symbol, and 96 REs in the third symbol (i.e., the first 48 (sub-bands 1 to 48) and the last 48 (sub-bands 193 to 240)). The 576 REs of PBCH 508 include the REs required for PBCH and the demodulation reference signal (DMRS) (not shown) required for coherent demodulation of PBCH 508.

[0099] Figure 6 This is an example of a portion of the resource mapping of a sidelink synchronization signal block 600 (S-SSB 600) in a time slot 602 used in conjunction with the depiction of the OFDM resource grid and the PC5 reference point in 5G NR. Figure 6 In the example, on the side link, S-SSB 600 is transmitted by the SynchRef side link UE based on a 160ms periodicity. The resource mapping for S-SSB 600 via the PC5 reference point (e.g., the PC5 link) differs from that for SSB 500 via the Uu reference point (e.g., the Uu link). Figure 5 Resource mapping.

[0100] In the S-SSB 600, the sidelink master synchronization signal 604 (S-PSS 604) is obtained using a 127 M sequence and the same generator and / or initial values ​​used with UuPSS 504, along with a cyclic shift (CS) given by the set {22, 65}. S-PSS 604 is mapped to 127 consecutive REs and repeated over two consecutive OFDM symbols.

[0101] In S-SSB 600, the side link auxiliary synchronization signal 606 (S-SSS 606) uses a 127 Gold sequence and is similar to Uu SSS 506 ( Figure 5 The same generator and / or initial values ​​and cyclic shifts are used together to obtain the S-SSS 606. The S-SSS 606 is mapped to 127 consecutive REs and repeated on 2 consecutive OFDM symbols.

[0102] In S-SSB 600, the Physical Side Link Broadcast Channel (PSBCH) 608 is mapped to 11 consecutive PRBs (132 subcarriers) and 9 OFDM symbols for the Nominal Cyclic Prefix (NCP) (see symbols 1 and 6 through 13). PSBCH 608 is mapped to 11 consecutive PRBs and 6 OFDM symbols for the Extended Cyclic Prefix (ECP) (not shown). In S-SSB 600, the first PSBCH symbol (see symbol 1) can be used for automatic gain control (AGC) training at the UE's receiver (Rx) side.

[0103] Figure 7 This is a diagram illustrating an example of the periodic repetition of a synchronization signal block burst set 700 (SSB burst set 700) according to some aspects of this disclosure. Figure 7 In this context, SSB burst set 700 includes multiple SSBs; however, an SSB burst set may include one or more SSBs. Multiple SSBs can be scheduled within a given cell. On the Uu link (i.e., between the base station and the UE), multiple SSBs and SSB beams (i.e., antenna beams) can be time-division multiplexed and grouped together within SSB burst set 700. This is provided as an example, not a limitation. Figure 7 In this design, each of the first SSB 701 (SSB 1) and the second SSB 702 (SSB2) through the Lth SSB 703 (SSB L) is depicted as having four beams (first beam 704, second beam 706, third beam 708, and fourth beam 710) from the antenna of the dispatching entity. The number of four antenna beams is chosen for illustrative purposes and not for limitation. Fewer than four antenna beams and more than four antenna beams are within the scope of this disclosure.

[0104] The quantity L represents the maximum number of SSBs in the SSB burst set 700. Depending on several aspects, L depends on the carrier frequency and parameter set utilized by the base station and UE. Generally, L can be equal to 4, 8, or 64. For example, when the carrier frequency f is less than or equal to 3 GHz (f ≤ 3 GHz) and the subcarrier spacing is 15 kHz or 30 kHz, the maximum number of SSBs L in the SSB burst set can be 4. For example, when the carrier frequency f is greater than 3 GHz and less than or equal to 6 GHz (3 GHz < f ≤ 6 GHz) and the subcarrier spacing is 15 kHz or 30 kHz, the maximum number of SSBs L in the SSB burst set can be 8. For example, when the carrier frequency f is greater than 6 GHz (f > 6 GHz) and the subcarrier spacing is 120 kHz or 240 kHz, the maximum number of SSBs L in the SSB burst set can be 64. Therefore, as the frequency increases and the beamwidth narrows, more beam scanning steps may occur, and more SSBs may be required.

[0105] like Figure 7 As depicted in the example, SSB burst set 700 can be a collection of one or more SSBs broadcast in a given cell. SSB burst set 700 can be broadcast within a 5ms window in the first or second half of a given frame (e.g., frame 714). SSB burst set 700 can include a maximum number L SSBs, where L is related to the frequency and parameter set (subcarrier spacing).

[0106] Additionally, SSB index values ​​(e.g., 0, 1, ..., L-1) can be encoded in the PBCH DMRS of each given SSB 701, 702, ..., 703. SSBs with the same index (in different SSB burst sets such as SSB burst set 7001 and SSB burst set 7002) can be used for the same purpose (e.g., to specify or associate with an antenna beam pointing in one direction). Additionally, SSBs with the same index (in different SSB burst sets) can be transmitted on quasi-co-located antenna ports, where the same gain and beamforming are applied to each quasi-co-located antenna port, and where delay spread, Doppler spread, Doppler shift, average gain, average delay, and spatial parameters are the same or substantially the same.

[0107] SSB burst sets 700 can be periodically repeated and broadcast by base stations at a given periodicity. For example, Figure 7 The first broadcast of SSB burst set 7001 and the repeated broadcasts of SSB burst set 7002 are described. The number of repetitions can be greater than one. Figure 7The diagram shows only the first broadcast of SSB burst set 7001 and the repeated broadcast of SSB burst set 7002 to avoid confusing the figures. Repeating of SSB burst sets can be used for, for example, retransmission, beam scanning, or both.

[0108] Depending on the context, the periodicity of the SSB burst set can be set by the operator to 5 milliseconds (ms), 10 ms, 20 ms, 40 ms, 80 ms, or 160 ms. The entire SSB burst set 700 occurs within a 5 ms duration (e.g., a window in the time domain), and this 5 ms duration can occur in the first or second half of a 10 ms frame. Figure 7 In the example, the first frame 712 and the first half of the second frame are shown to avoid confusing the illustrations. Figure 7 In the example, the periodicity of SSB burst set 700 is 20ms, and SSB burst set 700 is broadcast over a 5ms duration in the first half of the corresponding 10ms frame. Using a given periodicity (i.e., Figure 7 Within 20ms, different beams (e.g., the first beam 704, the second beam 706, the third beam 708, and the fourth beam 710) can be used to transmit groups of SSBs (e.g., a set of SSBs, multiple SSBs) in different directions.

[0109] For SSB and S-SSB designs in 5G NR, although the primary synchronization signal (PSS) is not used for link quality measurements, the PSS duration occupies a significant percentage of the SSB measurement window (up to 25% on Uu and up to 16% on SL). Despite carrying less information than the secondary synchronization signal (e.g., <2 bits on Uu and 1 bit on SL), the primary synchronization signal is allocated the same amount of time and frequency resources as the secondary synchronization signal. Additionally, the primary synchronization signal is based on a cyclically shifted M-sequence generated in the frequency domain, making it unsuitable for low-complexity time-domain processing prior to the Fast Fourier Transform (FFT).

[0110] UE (such as Figure 1 , Figure 2 and Figure 3The measurement of received signal strength is performed by the UE (or any of the scheduled entities) in conjunction with a handover, for example, from one cell or TRP to another cell or TRP (both referred to herein as neighboring cells). A full-duplex UE can measure the received power transmitted from neighboring cells operating using the same Radio Access Technology (RAT), simultaneously transmitting and receiving at the same frequency using the same RAT as its serving cell. However, when measuring cells operating at different frequencies (e.g., inter-frequency or intra-frequency neighboring cells) or cells operating with different RATs (e.g., inter-RAT neighboring cells), the UE (with a single receiver) may need to suspend all communication (uplink and downlink) with its serving cell and retune its RF receiver to the frequency used by the inter-frequency, intra-frequency, or inter-RAT neighboring cells. Once the measurement is complete, the UE can resume communication with its serving cell. The duration for which the UE suspends its communication with its serving cell is referred to herein as the Measurement Gap Length (MGL). In 5G NR, the configurable MGL corresponds to 1.5ms, 3ms, 3.5ms, 4ms, 5.5ms, and 6ms. There are also configurable measurement gap repetition periods (MGRPs) corresponding to 20ms, 40ms, 80ms, and 160ms. MGRPs correspond to the periodicity of the aforementioned SSB burst sets. In 5G NR, the RF retuning time is 0.5ms for carrier frequency measurements in the FR1 range and 0.25ms for the FR2 range. For example, a 4ms gap length for FR1 measurements will allow 3ms for actual measurement, and a 3.5ms gap length for FR2 measurements will allow 3ms for actual measurement. During the measurement gap, the UE measures the SSB of its neighboring cells (in the case of a Uu link) or the S-SSB of a SynchRef sidelink UE (in the case of a sidelink).

[0111] The network can utilize Synchronization Signaling / Physical Broadcast Channel Block Measurement Timing Configuration (SMTC) to configure the UE to tune to the SSB or S-SSB within the SMTC window. The network can select the SMTC window to provide sufficient time for the UE to measure the SSB or S-SSB of neighboring cells. However, if the MGL is unnecessarily long, and / or the SMTC window is unnecessarily long, the time spent by the UE tuning to inter-frequency, intra-frequency, or inter-RAT neighboring cells is wasted. During the wasted time, the UE and its serving cell cannot communicate, resulting in reduced uplink / downlink traffic throughput between the UE and its serving cell.

[0112] Figure 8A and Figure 8BTwo examples of MGL windows and corresponding SMTC windows according to some aspects of this disclosure are depicted. To avoid reduced uplink / downlink traffic throughput between the UE and its serving cell during the MGL window, the serving cell may configure appropriate MGL and SMTC for the UE based on the number of SSBs and the periodicity of SSB burst sets of neighboring cells.

[0113] exist Figure 8A In the first SSB burst set 800, the first time-frequency resources corresponding to the first set of four SSBs (first SSB 802 (SSB 1-1), second SSB 804 (SSB 2-1), third SSB 806 (SSB 3-1), and fourth SSB 808 (SSB 4-1)) are depicted. Figure 8B In the second SSB burst set 801, the second time-frequency resources corresponding to the second set of eight SSBs (first SSB 810 (SSB1-2), second SSB 812 (SSB 2-2), third SSB 814 (SSB 3-2), fourth SSB 816 (SSB 4-2), fifth SSB 818 (SSB 5-2), sixth SSB 820 (SSB 6-2), seventh SSB 822 (SSB 7-2), and eighth SSB 824 (SSB 8-2)) are depicted.

[0114] exist Figure 8A In the first time-frequency resource corresponding to the first SSB burst set 800, a first RF tuning time 830 and a second RF tuning time 832, each 0.5 ms, are allocated at the beginning and end of the first MGL window 834. During the first RF tuning time 830 and the second RF tuning time 832, the UE cannot measure the SSB and receive or transmit data and control from or to its serving cell. Figure 8A In the example, the first MGL window 834 is configured as 4ms (including the first RF tuning time 830 and the second RF tuning time 832), and the first SMTC window 836 is configured as 2ms. This configuration may have already been received at the UE from the serving cell before retuning. Accordingly, the UE can receive and measure the first SSB 802 (SSB 1-1), the second SSB 804 (SSB 2-1), the third SSB 806 (SSB 3-1), and the fourth SSB 808 (SSB 4-1) within the 2ms first SMTC window 836. Although not shown, the UE can perform measurements during the 3ms period between the end of the first RF tuning time 830 and the beginning of the second RF tuning time 832.

[0115] exist Figure 8BIn the second time-frequency resource corresponding to the second SSB burst set 801, a third RF tuning time 840 and a fourth RF tuning time 842, each 0.5 ms, are allocated at the beginning and end of the second MGL window 844, respectively. During the third RF tuning time 840 and the fourth RF tuning time 842, the UE cannot measure the SSB and cannot receive data and control from or transmit data and control to its serving cell. Figure 8B In the example, the second MGL window 844 is configured as 6ms (including the third RF tuning time 840 and the fourth RF tuning time 842), and the second SMTC window 846 is configured as 4ms. This configuration may have already been received at the UE from the serving cell before retuning. Therefore, the UE can receive and measure the first SSB 810 (SSB 1-2), the second SSB 812 (SSB 2-2), the third SSB 814 (SSB 3-2), the fourth SSB 816 (SSB 4-2), the fifth SSB 818 (SSB 5-2), the sixth SSB 820 (SSB 6-2), the seventh SSB 822 (SSB 7-2), and the eighth SSB 824 (SSB 8-2) within the 4ms second SMTC window. Although not shown, the UE can perform measurements during the 5ms period between the end of the third RF tuning time 840 and the beginning of the fourth RF tuning time 842.

[0116] The aspects described herein present the design of a PSS for a given SSB. These designs can facilitate reduced complexity for a given UE and reduced latency for the given UE in cell search and measurement operations. As an example, the aspects described herein can reduce downtime and throughput loss for a given UE by reducing the measurement gap length. In another example, the aspects described herein can improve the spectral efficiency of the network and reduce the overhead associated with the measurement of several downlink reference signals (DLRS) in BW-constrained scenarios, such as narrowband BWP, narrowband subchannels, and BW-constrained low-level UEs. Examples of DLRS include, but are not limited to, demodulation reference signals (DMRS), tracking reference signals (TRS), and phase tracking reference signals (PTRS).

[0117] Figure 9This is an illustration of a portion of an OFDM resource grid configured with resource mapping and measurement windows for five Synchronization Signal Blocks (SSBs) 901-905, according to some aspects of this disclosure. The SSBs may be configured with beamformed PSSs. The SSBs may be transmitted in the beamformed SSBs via Uu reference points (e.g., Uu links (links between scheduled entities and UEs)) and / or via PC5 reference points (e.g., PC5 side links between UEs configured to operate in side links). The SSBs may be transmitted in licensed or shared spectrum, all according to various aspects of this disclosure.

[0118] Each of the first SSB 901, the second SSB 902, the third SSB 903, the fourth SSB 904, and the fifth SSB 905 occupies T. SSB Each time unit multiplied by F SSB The resource grid area per frequency unit. In some examples, the time unit may be given based on the number of symbols or the number of sub-slots. In some examples, the frequency unit may be given based on the number of REs, the number of RE groups, the number of PRBs, or the number of PRB groups.

[0119] According to some aspects, T SSB ≥1 and is a positive integer. T SSB It can be less than, equal to or greater than the number of physical channels in the SSB.

[0120] According to some aspects, F SSB ≥1 and is a positive integer. F SSB It can be less than, equal to or greater than the number of physical channels in the SSB.

[0121] In some examples, T SSB and F SSB It can be jointly configured to obtain a constant k, and can be given as T. SSB * F SSB = k. Because T SSB and F SSB Since k is a positive integer, k is also a positive integer.

[0122] Within the SSB, according to some aspects of this disclosure, PSS 910 (including guard band 916) can be mapped to 1 ≤ T PSS ≤ T SSB one time unit and 1 ≤ F PSS ≤ F SSB One frequency unit. According to some examples, the guard band 916 can be optional.

[0123] The time-frequency resources assigned to PSS 910 can be equal to or less than the time-frequency resources assigned to SSS 912. To represent this in another way, T...PSS *F PSS ≤ T SSS * F SSS < T SSB * F SSB .

[0124] As shown in the examples of the first SSB 901, the second SSB 902, the third SSB 903, the fourth SSB 904, and the fifth SSB 905, the PSS 910 can be multiplexed with the SSS 912 and PBCH 914 in time, frequency, or both. Examples of multiplexing modes depicted by the first SSB 901, the second SSB 902, the third SSB 903, the fourth SSB 904, and the fifth SSB 905 are provided for illustrative and non-limiting purposes. An SSB (where one SSB occupies T in the time domain) SSB Each unit multiplied by F in the frequency domain SSB Other multiplexing modes of PSS 910, SSS 912 and PBCH 914 (and optionally, guard band 916) within this disclosure are within the scope of this disclosure.

[0125] According to some aspects of this disclosure, the first SSB of an SSB burst set (e.g., any of the exemplary first to fifth SSBs 901-905 and / or similarly configured SSBs) can be mapped to the nth symbol of a time slot, where 1 ≤ n ≤ T. SSB .

[0126] According to some aspects of this disclosure, the UE can obtain timing of neighboring cell or neighboring TRP (both referred to herein as neighboring cells) SSBs for Layer 1 (L1) and / or Layer 3 (L3) measurements. In some examples, the UE's serving cell can transmit timing of neighboring cell SSBs, SSB burst sets, or SMTC window information (such as, but not limited to, SMTC windows 836, 846 (Figure 8)), and the UE can transmit timing from the serving cell for receiving neighboring cell SSBs, SSB burst sets, or SMTC window information.

[0127] By combining the transmission and reception of SSB information from neighboring cells, inter-cell or inter-TRP mobility can be initiated by the network (NW) or by the UE, and the mobility process can be triggered by L1 measurement, L3 measurement, or both L1 and L3 measurement.

[0128] Depending on several aspects, the SSB Measurement Timing Configuration (SMTC) can be based on resource mappings of the SSS 912 and PBCH914 used for beamforming, such as combining... Figure 9 As shown and described.

All REs in each symbol of SSB 901 have non-zero values, except for REs within the first frequency guard band between any two of the PSS, SSS, and PBCH in each symbol of SSB 901.

It should be understood that the specific order or hierarchy of steps in these methods may be rearranged based on design preferences. The appended method claims present the elements of various steps in a sample order and are not intended to be limited to the specific order or hierarchy presented, unless specifically stated herein. While some examples illustrated herein depict only the time and frequency domains, additional domains such as the spatial domain are also contemplated in this disclosure.

[0253] The foregoing description is provided to enable any person skilled in the art to practice the various aspects described herein. Various modifications to these aspects will be apparent to those skilled in the art, and the general principles defined herein can be applied to other aspects. Therefore, the claims are not intended to be limited to the aspects shown herein, but are to be accorded the full scope consistent with the text of the claims, wherein references to the singular form of an element are not intended to mean “one and only one”, but rather “one or more”, unless specifically stated otherwise. Unless specifically stated otherwise, the term “some” refers to one or more.

[0254] As used herein, the word “obtain” can mean, for example, acquiring, calculating, constructing, deriving, determining, receiving, and / or retrieving. The foregoing list is exemplary and not restrictive. All structural and functional equivalents of elements throughout the various aspects described herein that are known to a person of ordinary skill in the art or will later be known are expressly incorporated herein by reference and are intended to be covered by the claims. Furthermore, nothing disclosed herein is intended to be offered to the public, whether or not such disclosure is explicitly recited in the claims. No claim element should be construed under 35 USC §112(f) unless the element is expressly recited using the phrase “component for…” or, in the case of a method claim, using the phrase “step for…”.

[0255] As used herein, the terms "determine" or "determine" encompass a wide variety of actions, and therefore, "determine" can include calculation, computation, processing, derivation, investigation, searching (such as by searching in a table, database, or other data structure), reasoning, probing, measurement, etc. Additionally, "determine" can include receiving (such as receiving information), accessing (such as accessing data stored in memory), sending (such as sending information), etc. Furthermore, "determine" can include parsing, selecting, obtaining, choosing, building, and other similar actions.

[0256] As used herein, the phrase referring to “at least one of” a list of items refers to any combination of those items (including a single member). For example, “at least one of a, b, or c” is intended to cover: a, b, c, ab, ac, bc, and abc. As used herein, “or” is intended to be interpreted in an inclusive sense unless otherwise expressly indicated. For example, “a or b” can include only a, only b, or a combination of a and b. Similarly, phrases referring to A and / or B can include only A, only B, or a combination of A and B.

[0257] As used herein, unless otherwise explicitly indicated, “or” is intended to be interpreted in an inclusive sense. For example, unless otherwise explicitly indicated, “based on” may be used interchangeably with “at least partially based on,” “associated with,” or “according to.” Specifically, unless the phrase in the context refers to “based on only one” or an equivalent, it may be based solely on “one” or on a combination of “one” and one or more other factors, conditions, or information, whether it is “based on one” or “at least partially based on one.”

[0258] The various exemplary components, logic units, logic blocks, modules, circuits, operations, and algorithmic processes described in conjunction with the examples disclosed herein can be implemented as electronic hardware, firmware, software, or a combination of hardware, firmware, or software, including the structures disclosed in this specification and their structural equivalents. This interchangeability of hardware, firmware, and software has been generally described in terms of its functionality and exemplified in the various exemplary components, blocks, modules, circuits, and processes described above. Whether such functionality is implemented in hardware, firmware, or software depends on the specific application and the design constraints imposed on the overall system.

Therefore, the claims are not intended to be limited to the examples shown herein, but are to be granted the widest scope consistent with this disclosure, the principles disclosed herein, and the novel features.

[0260] Additionally, the various features described in this specification in the context of individual examples may also be implemented in combination in a single embodiment. Conversely, the various features described in the context of a single embodiment may also be implemented individually or in any suitable sub-combination in multiple examples. Thus, although features may be described above as functioning in a particular combination, and even initially claimed in this way, one or more features from the claimed combination may be removed from the combination in some cases, and the claimed combination may involve sub-combinations or variations of sub-combinations.

[0261] Similarly, although operations are depicted in a specific order in the diagrams, this should not be construed as requiring such operations to be performed in the specific order shown or in sequential order, or to perform all illustrated operations to achieve the desired result. Furthermore, the accompanying figures may schematically depict one or more example processes in the form of flowcharts or flow diagrams. However, other operations not depicted may be incorporated into the schematically illustrated example processes. For example, one or more additional operations may be performed before, after, simultaneously with, or between any of the illustrated operations. In some environments, multitasking and parallel processing may be advantageous. Moreover, the separation of various system components in the examples described above should not be construed as requiring such separation in all examples, but rather should be understood as meaning that the described program components and systems can generally be integrated together in a single software product or encapsulated in multiple software products.
