SYNCHRONIZATION SIGNAL BLOCK DESIGNS FOR WIRELESS COMMUNICATION
Reference to related requests [0001] This application claims priority for and the benefit of provisional application no. 62 / 485,822 filed with the United States Patent and Trademark Department on April 14, 2017, and non-provisional application no. 15 / 936,200 filed with the United States Patent and Trademark Department on March 26, 2018, the entire contents of which are incorporated herein by reference as if fully set out below in full and for all applicable purposes.
Technical field [0002] The technology discussed below generally refers to wireless communication systems and, more particularly, to synchronous signal designs and related methods for wireless communication.
Introduction [0003] Next generation wireless networks such as the new Radio 5G (NR) can support an increased number of services and devices including, for example, smartphones, mobile devices, Internet of Things (loT) devices, sensor networks, and a lot more. As compared to current networks, 5G NR can provide higher performance such as higher bit rates, higher speed mobility, and / or lower latency across multiple applications. In addition, 5G NR networks may have higher connection density, allocation of new spectrum, and use licensed and unlicensed bands. In 5G NR, requirements

2/49 synchronization can be based on the services provided and the network infrastructure. For example, device-to-device (D2D), non-hierarchical (P2P), vehicle to vehicle (V2V) and loT communications require precise synchronization. In addition, next generation networks may introduce new capabilities and air interfaces related to time sensitive networks that may need synchronization support from the network. Therefore, sync signal designs and related features are important in 5G NR network design.
Summary of some examples [0004] The following provides a simplified summary of one or more aspects of the present disclosure to provide a basic understanding of such aspects. This summary is not an extensive overview of all the resources considered in the disclosure and is not intended to identify key or critical elements of all aspects of the disclosure or to outline the scope of all or any aspects of the disclosure. Its sole purpose is to present some concepts of one or more aspects of the revelation in a simplified form as a prelude to the more detailed description that is presented later.
[0005] Aspects of the present disclosure provide several synchronization signal block (SS) designs that can facilitate channel estimation and demodulation in new 5G Radio (NR) networks.

The programming entity programs a plurality of time domain symbols to transmit a synchronization signal block (SS) and a supplementary channel. The SS block includes a primary sync signal (PSS), a secondary sync signal (SSS), and a physical broadcast channel (PBCH).

The detailed description includes specific details for the purpose of providing a complete understanding of various concepts. However, it will be evident to those skilled in the art that these concepts can be put into practice without these specific details. In some instances, well-known structures and components are shown in the form of a block diagram to avoid obscuring such concepts.

8/49 platform types, devices, systems, formats, sizes, packaging arrangements, different. For example, modalities and / or uses may originate through integrated chip modalities and other non-module component based devices (eg, end user devices, vehicles, communication devices, computing devices, industrial equipment, retail devices / purchase, medical devices, AI-enabled devices, etc.) While some examples may or may not be specifically targeted at use cases or applications, a wide variety of applicability of the described innovations may occur.

9/49 final, etc., of variable sizes, shapes and constitution.
[00027] Aspects of the present disclosure provide several synchronization signal block (SS) designs that can facilitate channel estimation and demodulation in new 5G Radio (NR) networks. An example SS block includes a set of frequency-time resources that are allocated to carry a Primary Sync Signal (PSS), a Secondary Sync Signal (SSS), and a Physical Broadcast Channel (PBCH) that are multiplexed by time and / or frequency in the SS block. In some instances, unused frequency-time resources from the SS block can be used or allocated to supplemental channels that can improve and / or extend wireless link coverage.
[00028] The various concepts presented throughout this revelation can be implemented through a wide variety of telecommunication systems, network architectures and communication standards. With reference now to Figure 1, as an illustrative example without limitation, several aspects of the present disclosure are illustrated with reference to a wireless communication system 100. The wireless communication system 100 includes three domains of interaction: a core network 102, a radio access network (RAN) 104, and user equipment (UR) 106. Due to the wireless communication system 100, the UE 106 can be enabled to carry out data communication with an external data network 110, such as (but not limited to) the Internet.
[00029] RAN 104 can implement any suitable wireless communication technology or technologies
Petition 870190101977, of 10/10/2019, p. 15/83
10/49 to provide radio access to the UE 106. As an example, the RAN 104 can operate according to the new specifications Radio (NR) of the Society of Project third generation (3GPP), often referred to as 5G. as another example, RAN 104 can operate under a hybrid of 5G NR and developed Universal Terrestrial Radio Access Network (eUTRAN) standards, often referred to as LTE. 3GPP refers to this hybrid RAN as a next generation RAN, or NG-RAN. Of course, many other examples can be used without the scope of the present disclosure.
[00030] As illustrated, RAN 104 includes a plurality of base stations 108. In broad terms, a base station is a network element in a radio access network responsible for transmitting and receiving radio in one or more cells to or from an UE. In different technologies, patterns or contexts, a base station can be referred to in a varied way by those skilled in the art as a base transceiver station (BTS), a radio base station, a radio transceiver, a transceiver function, a set basic services (BSS), a set of extended services (ESS), an access point (AP), a Node B (NB), an eNode B (eNB), a gNode B (gNB) or some other suitable terminology.
[00031] Radio access network 104 is further illustrated supporting wireless communication for multiple mobile devices. A mobile device can be mentioned as user equipment (UE) in 3GPP standards, but it can also be mentioned by those skilled in the art as a mobile station (MS), a subscriber station, a mobile unit, a subscriber unit, a
Petition 870190101977, of 10/10/2019, p. 16/83
11/49 wireless unit, a remote unit, a mobile device, a wireless device, a wireless communication device, a remote device, a mobile subscriber station, an access terminal (AT), a mobile terminal, a wireless terminal, remote terminal, handset, terminal, user agent, mobile client, or some other suitable terminology. A UE can be a device that provides a user with access to network services.
[00032] In the present document, a mobile device does not necessarily need to be able to move and can be stationary. The term mobile device or mobile device refers widely to a diverse set of devices and technologies. UEs can include several structural hardware components sized, shaped and arranged to aid in communication; such components may include antennas, antenna assemblies, RF chains, amplifiers, one or more processors, etc., electrically coupled together. For example, some non-limiting examples of a mobile device include a mobile, a cell phone (cell), a smartphone, a session initiation protocol (SIP) phone, a laptop, a personal computer (PC), a notebook, a netbook, a smartbook, a tablet, a personal digital assistant (PDA), and a wide range of embedded systems, for example, corresponding to an Internet of things (ToT). A mobile device can additionally be an automotive or other transport vehicle, a remote sensor or driver, a robot or robotic device, a satellite radio, a global positioning system (GPS) device, an object tracking device, a
Petition 870190101977, of 10/10/2019, p. 17/83
12/49 drone, a multicopter, a quadcopter, a remote control device, a consumer and / or wearable device such as glasses, a wearable camera, a virtual reality device, a smart watch, a health or fitness tracker, a digital audio player (for example, MP3 player), a camera, a game console, etc. A mobile device can additionally be a digital home or smart home device such as a home audio, video and / or multimedia device, an appliance, a vending machine, smart lighting, a home security system, a smart meter, etc. . A mobile device can additionally be an intelligent energy device, a security device, a solar panel or solar array, a municipal infrastructure device that controls electricity (for example, a smart grid), lighting, water, etc., a enterprise and industrial automation device, a logistics controller, agricultural equipment; military defense equipment, vehicles, aircraft, ships, and armament, etc. In addition, a mobile device can provide connected support for medicine or telemedicine, for example, healthcare at a distance. Telehealth devices may include telehealth monitoring devices and telehealth management devices, the communication of which may receive priority access or preferential treatment over other types of information, for example, in terms of priority access for transporting critical service data, and / or QoS relevant for transporting critical service data.
[00033] Wireless communication between a RAN 104
Petition 870190101977, of 10/10/2019, p. 18/83
13/49 and an UE 106 can be described as using an air interface. Transmissions through the air interface from a base station (e.g., base station 108) to one or more UEs (e.g., UE 106) can be referred to as downlink (DL) transmission. According to certain aspects of the present disclosure, the term downlink can refer to a transmission from point to multipoint originating in a programming entity (described further below, for example, base station 108). Another way to describe this scheme can be to use the term broadcast channel multiplexing. Transmissions from a UE (e.g., UE 106) to a base station (e.g., base station 108) can be referred to as uplink (UL) transmissions. In accordance with additional aspects of the present disclosure, the term uplink can refer to a transmission from point to point originating in a programmed entity (described further below; for example, UE 106).
[00034] In some examples, access to the air interface can be programmed, in which a programming entity (for example, a base station 108) allocates resources for communication between some or all devices and equipment in its service area or cell. In the present disclosure, as further discussed below, the programming entity may be responsible for programming, assigning, reconfiguring, and releasing resources to one or more programmed entities. That is, for programmed communication, UEs 106 that can be programmed entities, can use resources allocated by the programming entity 108.
[00035] Base stations 108 are not the only ones
Petition 870190101977, of 10/10/2019, p. 19/83
14/49 entities that can function as programming entities. That is, in some instances, a UE may function as a programming entity, programming resources for one or more programmed entities (for example, one or more other UEs).
[00036] As illustrated in figure 1, a programming entity 108 can broadcast downlink traffic 112 to one or more programmed entities 106. Broadly speaking, programming entity 108 is a node or device responsible for scheduling traffic on a network wireless communications, including downlink traffic 112 and in some examples, uplink traffic 116 from one or more programmed entities 106 to programming entity 108. On the other hand, programmed entity 106 is a node or device that receives information downlink control 114, including, but not limited to, programming information (for example, a lease), timing or synchronization information, or other control information from another entity on the wireless communication network such as programming entity 108 .
[00037] In general, base stations 108 may include a backhaul interface for communication with a backhaul portion 120 of the wireless communication system. Backhaul 120 can provide a link between a base station 108 and core network 102. In addition, in some examples, a backhaul network can provide interconnection between the respective base stations 108. Various types of backhaul interfaces can be employed, such as direct physical connection, a virtual network, or the like using any suitable transport network.
Petition 870190101977, of 10/10/2019, p. 20/83
15/49 [00038] Core network 102 can be part of wireless communication system 100, and can be independent of the radio access technology used in RAN 104. In some examples, core network 102 can be configured according to 5G standards (eg 5GC). In other examples, the core network 102 can be configured according to a developed packet core 4G (EPC) or any other suitable configuration or standard.
[00039] Figure 2 is a conceptual illustration of an example of a radio access network. As an example and without limitation, a schematic illustration of a RAN 200 is provided. In some examples, the RAN 200 can be the same as the RAN 104 described above and illustrated in figure 1. The geographical area covered by the RAN 200 can be divided into cellular regions (cells) that can be uniquely identified by a user device (UE) based on an identification broadcast from an access point or base station. Figure 2 illustrates macro cells 202, 204 and 206, and a small cell 208, each of which may include one or more sectors (not shown). A sector is a subarea of a cell. All sectors in a cell are served by the same base station. A radio link in a sector can be identified by a unique logical identification that belongs to that sector. In a cell that is divided into sectors, the multiple sectors in a cell can be formed by groups of antennas with each antenna responsible for communicating with UEs in a portion of the cell.
[00040] In figure 2, two base stations 210 and 212 are shown in cells 202 and 204; and a third
Petition 870190101977, of 10/10/2019, p. 21/83
16/49 base station 214 is shown controlling a remote radio head (RRH) 216 in cell 206. That is, a base station can have an integrated antenna or can be connected to an antenna or RRH by feeder cables. In the illustrated example, cells 202, 204 and 126 can be referred to as macro cells, since base stations 210, 212 and 214 support cells having a large size. In addition, a base station 218 is shown in small cell 208 (e.g., a microcell, picocell, femtocell, home base station, home node B, home eNode B, etc.) that can overlap with one or more macro cells. In this example, cell 208 can be referred to as a small cell, since base station 218 supports a cell having a relatively small size. Cell sizing can be done according to system design as well as component limitations.
[00041] It should be understood that the radio access network 200 can include any number of wireless base stations and cells. In addition, a relay node can be deployed to extend the size or area of coverage of a given cell. Base stations 210, 212, 214, 218 provide wireless access points to a core network for any number of mobile devices. In some examples, the base stations 210, 212, 214, and / or 218 may be the same as the base station / programming entity 108 described above and illustrated in figure 1.
[00042] Figure 2 also includes a quacopter or drone 220, which can be configured to function as a base station. That is, in some instances, a cell may not necessarily be stationary, and the geographic area
Petition 870190101977, of 10/10/2019, p. 22/83
17/49 of the cell can move according to the location of a mobile base station like the quadcopter 220.
[00043] In RAN 200, cells can include UEs that can be in communication with one or more sectors of each cell. In addition, each base station 210, 212, 214, 218 and 220 can be configured to provide an access point to a core network 102 (see figure 1) for all UEs in the respective cells. For example, UEs 222 and 224 may be in communication with base station 210; UEs 226 and 228 may be in communication with base station 212; UEs 230 and 232 may be in communication with the base station 214 via RRH 216; UE 234 can be in communication with base station 218; and UE 236 may be in communication with mobile base station 220. In some instances, UEs 222, 224, 226, 228, 230, 232, 234, 236, 238, 240 and / or 242 may be the same as UE / entity programmed 106 described above and illustrated in figure 1.
[00044] In some examples, a mobile network node (for example, quadcopter 220) can be configured to function as a UE. For example, quadcopter 220 can operate in cell 202 for communicating with base station 210.
[00045] In an additional aspect to RAN 200, secondary link signals can be used between UEs without necessarily relying on control information or the programming of a base station. For example, two or more UEs (for example, UEs 226 and 228) can communicate with each other using non-hierarchical (P2P) or secondary link 227 signals without relaying that communication through a base station (for example, base station 212). In an additional example, UE 238 is illustrated by communicating with UEs
Petition 870190101977, of 10/10/2019, p. 23/83
18/49
240 and 242. Here, UE 238 can function as a programming entity or a non-primary secondary link device (for example, secondary). In yet another example, a UE can function as a programming entity in a device-to-device (D2D), non-hierarchical (P2P) or vehicle-to-vehicle (V2V) network, and / or to a mesh network. In an example of a mesh network, UEs 240 and 242 can optionally communicate directly with each other in addition to communicating with programming entity 238. Thus, in a wireless communication system with programmed access to frequency-time resources and having a cellular configuration, a P2P configuration, or a fabric configuration, a programming entity and one or more programmed entities can communicate using the programmed resources.
[00046] In the radio access network 200, the ability of a UE to communicate while moving, regardless of its location, is referred to as mobility. The various physical channels between the UE and the radio access network are generally assembled, maintained, and released under the control of a mobility and access management function (MFA, not shown, part of the core network 102 in figure 1 ), which can include a security context management (SOME) function that manages the security context for both the control plan and user plan functionality, and a security anchor function (SEAF) that performs authentication.
[00047] In various aspects of the disclosure, a radio access network 200 can use DL-based mobility or UL-based mobility to enable
Petition 870190101977, of 10/10/2019, p. 24/83
19/49 mobility and handovers (ie transferring the connection from one UE from one radio channel to another). In a network configured for DL-based mobility, during a call with a programming entity, or at any other time, a UE can monitor various parameters of the signal from its cell in service as well as various parameters of neighboring cells. Depending on the quality of these parameters, the UE can maintain communication with one or more of the neighboring cells. During that time, if the UE moves from one cell to another, or if the signal quality of a neighboring cell exceeds that of the cell in service for a given amount of time, the UE can undertake a handoff or handover from the cell in service to the neighboring (target) cell. For example, UE 224 (illustrated as a vehicle, although any suitable form of UE can be used) can move from the geographic area corresponding to its cell in service 202 to the geographic area corresponding to a neighbor cell 206. When signal strength or quality from neighboring cell 206 exceeds that of its in-service cell 202 for a given amount of time, UE 224 may transmit a report message to its in-service base station 210 indicating that condition. In response, the UE 224 can receive a handover command, and the UE can be handovered to cell 206.
[00048] In a network configured for UL-based mobility, UL reference signals from each UE can be used by the network to select a cell in service for each UE. In some examples, base stations 210, 212 and 214/216 can broadcast sync signals
Petition 870190101977, of 10/10/2019, p. 25/83
20/49 Unified (for example, Unified Primary Sync Signals (PSSs), Unified Secondary Sync Signals (SSSs) and Unified Physical Broadcast Channels (PBCH)). In some embodiments, PSS, SSS and PBCH can be included in an independent synchronization signal (SS) block. In some examples, the network may periodically transmit an SS burst containing multiple SS blocks. Two exemplary SS bursts 300 are illustrated in Figure 3, although a set of SS bursts can include any suitable number of SS bursts. In some instances, a set of SS bursts may include periodic transmissions of the SS bursts 300, for example, every X milliseconds (ms), although any SS burst periodicity, or an aperiodic set of SS bursts may also be used. Each SS 300 burst can include a predetermined number of SS 302 blocks (N SS blocks are illustrated in figure 3). Each SS 302 block can include PSS, SSS and PBCH multiplexed in time and / or frequency.
[00049] With reference again to figure 2, UEs 222, 224, 226, 228, 230 and 232 can receive the SS 302 block containing the unified synchronization signals, derive the carrier frequency and partition timing from the synchronization signals and in response to the timing derivation, transmit a reference or pilot uplink signal. The uplink pilot signal transmitted by a UE (for example, UE 224) can be simultaneously received by two or more cells (for example, base stations 210 and 214/216) on the radio access network 200. Each cell can measure a pilot signal strength and radio access network (for example, one or more of base stations 210 and
Petition 870190101977, of 10/10/2019, p. 26/83
21/49
214/216 and / or a central node in the core network) can determine a cell in service for UE 224. As UE 224 moves through radio access network 20, the network can continue to monitor the signal uplink pilot transmitted by UE 224. When the signal strength or quality of the pilot signal measured by a neighboring cell exceeds that of the signal strength or quality measured by the cell in service, network 200 can handover the UE 224 from the cell in service to the neighboring cell, with or without informing the UE 224.
[00050] Although the synchronization signals (for example, SS 302 nozzles) transmitted by base stations 210, 212 and 214/216 can be unified, the synchronization signal may not identify a specific cell, but instead it can identify a zone of multiple cells operating at the same frequency and / or with the same timing. The use of zones in 5G networks or other next generation communication networks enables the uplink-based mobility structure and improves the efficiency of both the UE and the network, since the number of mobility messages that need to be exchanged between the UE and the network can be reduced.
[00051] In various implementations, the air interface in the radio access network 200 can use licensed spectrum, unlicensed spectrum or shared spectrum. Licensed spectrum provides exclusive use of a portion of the spectrum, usually by virtue of a mobile network operator acquiring a license from a government regulator. Unlicensed spectrum provides shared use of a portion of the spectrum without the need for
Petition 870190101977, of 10/10/2019, p. 27/83
22/49 a license granted by the government. Although compliance with some technical rules is generally still required to access unlicensed spectrum, generally any operator or device can have access. Shared spectrum can be comprised between licensed and unlicensed spectrum, where technical rules or limitations may be required to access the spectrum, however the spectrum can still be shared by multiple operators and / or multiple RATs. For example, a license holder for a portion of licensed spectrum may provide licensed shared access (LSA) to share that spectrum with other parties, for example, under conditions determined by appropriate licensee, to have access.
[00052] For transmissions over the radio access network 200 to obtain a low block error rate (BLER) while still obtaining very high data rates, channel encoding can be used. That is, wireless communication can generally use an appropriate error correction block code. In a typical block code, a sequence or information message is divided into code blocks (CBs), and an encoder (for example, a CODEC) in the transmission device then mathematically adds redundancy to the information message. The exploitation of this redundancy in the coded information message can improve the reliability of the message, enabling correction for any bit errors that may occur due to noise.
[00053] In previous 5G NR specifications, user data is encoded using
Petition 870190101977, of 10/10/2019, p. 28/83
23/49 quasi-cyclic low density parity (LDPC) with two different base charts: one base chart is used for large code blocks and / or high code rates, while the other base chart is used in another way . Control information and the physical broadcast channel (PBCH) are encoded using Polar encoding, based on embedded strings. For these channels, punching, shortening and repetition are used for rate matching.
[00054] However, those of ordinary skill in the art will understand that aspects of the present disclosure can be implemented using any suitable channel code. Various implementations of programming entities 108 and programmed entities 106 may include appropriate hardware and capabilities (for example, an encoder, a decoder and / or a CODEC) to use one or more of these channel codes for wireless communication.
[00055] The air interface in the radio access network 200 can use one or more multiple access and multiplexing algorithms to enable simultaneous communication of the various devices. For example, 5G NR specifications provide multiple access for UL transmissions from UEs 222 and 224 to base station 210 and to multiplex DL transmissions from base station 210 to one or more UEs 222 and 224 using split multiplexing orthogonal frequency (OFDM) with a cyclic prefix (CP). In addition, for UL transmissions, 5G NR specifications provide support for discrete Fourier transform spreading OFDM (DFT-s-OFDM) with a CP (also referred to as single carrier FDMA
Petition 870190101977, of 10/10/2019, p. 29/83
24/49 (SC-FDMA)). However, within the scope of the present 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), scarce multiple access (SOMA), resource spread multiple access (RSMA) or other suitable multiple access schemes. In addition, multiplexing DL transmissions from base station 210 to UEs 222 and 224 can be provided using time division multiplexing (TDM), code division multiplexing (CDM), frequency division multiplexing (FDM), orthogonal frequency division multiplexing (OFDM), scarce code multiplexing (SCM) or other suitable multiplexing schemes.
[00056] Various aspects of the present disclosure will be described with reference to an OFDM waveform, schematically illustrated in figure 4. It should be understood by those of ordinary skill in the art that the various aspects of the present disclosure can be applied to a waveform DFT-s-OFDMA in substantially the same manner as described below. That is, although some examples of the present disclosure may focus on an OFDM link for clarity, it should be understood that the same principles can also be applied to DFT-s-OFDMA waveforms.
[00057] In the present disclosure, a frame refers to a predetermined duration (for example, 10 ms) for wireless transmissions, with each frame consisting, for example, of 10 subframes of 1 ms each. In a given
Petition 870190101977, of 10/10/2019, p. 30/83
25/49 carrier, there may be one set of frames on the uplink (UL) and another set of frames on the downlink (DL). Referring now to Figure 4, an expanded view of an exemplary DL subframe 402 is illustrated, showing an OFDM 404 resource network. However, how those skilled in the art will readily recognize the PHY transmission structure for any specific application may vary from the example described here, depending on any number of factors. Here, time is in the horizontal direction with units of OFDM symbols; and frequency is in the vertical direction with subcarrier units or tones.
[00058] The 404 resource network can be used to schematically represent frequency-time resources for a given antenna port. That is, in a MIMO implementation with multiple available antenna ports, a corresponding multiple number of networks of 404 resources may be available for communication. The resource network 404 is divided into multiple resource elements (REs) 406. An RE, which is 1 subcarrier x 1 symbol, is the smallest discrete part of the frequency-time network, and contains a unique complex value representing data from a physical channel or sign. Depending on the modulation used in a specific implementation, each RE can represent one or more bits of information. In some examples, a block of REs may be referred to as a physical resource block (PRB) or more simply a resource block (RB) 408, which contains any suitable number of consecutive subcarriers in the frequency domain. In one example, an RB can include 12 subcarriers, a number independent of the numerology used. In some examples,
Petition 870190101977, of 10/10/2019, p. 31/83
26/49 depending on numerology, an RB can include any suitable number of consecutive OFDM symbols in the time domain. In the present disclosure, it is assumed that a single RB such as the RB 408 corresponds entirely to a single communication direction (transmission or reception for a given device).
[00059] A UE generally uses only a subset of the 404 resource network. A RB can be the smallest unit of resources that can be allocated to a UE. Thus, the more RBs programmed for a UE, and the higher the modulation scheme chosen for the air interface, the higher the data rate for the UE.
[00060] In this illustration, RB 408 is shown to occupy less than the total bandwidth of subframe 402, with some subcarriers illustrated above and below RB 408. In a given implementation, subframe 402 may have a bandwidth corresponding to any number of one or more RBs 408. Furthermore, in this illustration, the RB 408 is shown to occupy less than the total duration of subframe 402, although this is merely a possible example.
[00061] Each subframe (for example, 1 ms subframe 402) can consist of one or multiple adjacent partitions. In the example shown in Figure 4, a subframe 402 includes four partitions 410, as an illustrative example. In some examples, a partition can be defined according to a specified number of OFDM symbols with a given cyclic prefix length (CP). For example, a partition can include 7 or 14 OFDM symbols with a nominal CP. Additional examples may include mini
Petition 870190101977, of 10/10/2019, p. 32/83
27/49 partitions having a shorter duration (for example, one or two OFDM symbols). These mini-partitions can in some cases be transmitted using resources programmed for continuous partition transmissions to the same or different UEs.
[00062] An expanded view of one of partitions 410 illustrates partition 410 including a control region 412 and a data region 414. In general, the control region 412 can contain control channels (for example, PDCCH) and the region data 414 can contain data channels (for example, PDSCH or PUSCH). Of course, a partition can contain all DL, all UL, or at least one DL portion and at least one UL portion. The simple structure illustrated in figure 4 is of an exemplary nature only, and different partition structures can be used and may include one or more of each of the control region (s) and data region (s).
[00063] Although not shown in figure 4, the various REs 406 in an RB 408 can be programmed to contain one or more physical channels, including control channels, shared channels, data channels, etc. Other REs 406 on the RB 408 may also contain pilots, or reference signals, including, but not limited to, a demodulation reference signal (DMRS), a control reference signal (CRS), or a sound reference signal (SRS ). These pilots or reference signals can provide a receiving device to perform channel estimation of the corresponding channel, which can enable coherent demodulation / detection of the control and / or data channels on the RB 408.
Petition 870190101977, of 10/10/2019, p. 33/83
28/49 [00064] In a DL transmission, the transmitting device (for example, programming entity 108) can allocate one or more REs 406 (for example, in a control region 412) to load DL 114 control information including one or more DL control channels such as a PBCH, a PSS, an SSS, an SS block, a physical control format indicator channel (PCFICH), a physical hybrid automatic repeat request (PHICH) channel (HARQ), and / or a physical downlink control channel (PDCCH), etc., for one or more programmed entities 106. The PCFICH provides information to assist a receiving device in receiving and decoding the PDCCH. The PDCCH carries downlink control information (DCI) including, but not limited to, power control commands, programming information, a lease, and / or an assignment of REs for DL and UL transmissions. 0 PHICH carries HARQ feedback streams as an acknowledgment (ACK) or negative acknowledgment (NACK). HARQ is a technique well known to those of ordinary skill in the art where the integrity of packet transmissions can be verified on the receiving side for accuracy, for example, using any suitable health check mechanism, such as a checksum or a cyclic redundancy check (CRC). If the integrity of the transmission is confirmed, an ACK can be transmitted, while if it is not confirmed, a NACK can be transmitted. In response to a NACK, the transmitting device can send an HARQ retransmission, which it can implement combining chase, incremental redundancy, etc.
Petition 870190101977, of 10/10/2019, p. 34/83
29/49 [00065] In a UL transmission, the transmitting device (for example, programmed entity 106) can use one or more REs 406 to contain UL 118 control information including one or more UL control channels, such as a control channel. physical uplink control (PUCCH) for programming entity 108. UL control information can include a variety of package types and categories, including pilots, reference signals, and information configured to enable or assist in decoding uplink data transmissions. In some examples, control information 118 may include a scheduling request (SR), for example, a request to scheduling entity 108 to schedule uplink transmissions. Here, in response to the SR transmitted on the control channel 118, the programming entity 108 can transmit downlink control information 114 which can program resources for uplink packet transmissions. UL control information can also include HARQ feedback, channel status feedback (CSF) or any other suitable UL control information.
[00066] In addition to control information, one or more 406 REs (for example, in data region 414) can be allocated for user data or traffic data. Such traffic can be contained in one or more traffic channels, such as for a DL transmission, a physical downlink shared channel (PDSCH), or for an UL transmission, a physical uplink shared channel (PUSCH). In some examples, one or more REs 406 in data region 414 can be configured to contain system information blocks (SIBs) containing information that can enable access to a
Petition 870190101977, of 10/10/2019, p. 35/83
30/49 given cell.
[00067] The channels or carriers described above and illustrated in figures 1 and 4 are not necessarily all channels or carriers that can be used between a programming entity 108 and programmed entities 106, and those with common knowledge in the art will recognize that other channels or carriers can be used in addition to those illustrated, as other traffic, control and feedback channels.
[00068] These physical channels described above are usually multiplexed and mapped to transport channels for manipulation in the media access control layer (MAC). Transport channels contain blocks of information called transport blocks (TB). The transport block size (TBS), which can correspond to a number of bits of information, can be a controlled parameter, based on the modulation and coding scheme (MCS) and the number of RBs in a given transmission.
[00069] In OFDM to maintain orthogonality of the subcarriers or tones, the subcarrier spacing can be equal to the inverse of the symbol period. A numerology of an OFDM waveform refers to its specific subcarrier spacing and cyclic prefix (CP) overhead. Scalable numerology refers to the network's ability to select different subcarrier spacing, and therefore, with each spacing, select the corresponding symbol duration, including the CP length. With scalable numerology, a nominal subcarrier spacing (SCS) can be scaled up or down by multiple integers. Thus, regardless of CP overhead
Petition 870190101977, of 10/10/2019, p. 36/83
31/49 and the selected SCS, symbol limits can be aligned on certain common symbol multiples (for example, aligned on the limits of each 1 ms subframe). The SCS range can include any suitable SCS. For example, scalable numerology can support SCS ranging from 15 kHz to 480 kHz.
[00070] To illustrate this concept of scalable numerology, figure 5 shows a first RB 502 having nominal numerology, and a second RB 504 having scaled numerology. As an example, the first RB 502 can have a 'nominal' subcarrier spacing (SCS _n ) of 30 kHz, and a 'nominal' symbol _n duration of 333 με. here, in the second RB 504, the scaled numerology includes an SCS scaled twice the nominal SCS, or 2 x SCS _n = 60 kHz. As this provides twice the bandwidth per symbol, it results in a symbol duration shortened to contain the same information. Thus, in the second RB 504, scaled numerology includes a scaled symbol duration of half the nominal symbol duration, or (duration _n symbol) -e 2 = 167 με.
[00071] In some aspects of the disclosure, a programming entity 108 (for example, gNB) can transmit control and synchronization signals (for example, PSS, SSS and PBCH) to one or more programmed entities 108 (for example, UE) using multiple SS block designs. Each SS block can include a PSS, SSS and PBCH. Figure 6 is a diagram illustrating an example SS block 600 according to some aspects of the disclosure. The SS 600 block can be the same as the SS 302 block in Figure 3 and can be included in the SS 300 burst. The SSB 600 block includes four
Petition 870190101977, of 10/10/2019, p. 37/83
32/49 OFDM symbols, numbered in ascending order from 0 to 3 in the SS block. The SS 600 block provides various control and synchronization signals. In this example, the frequency-time resources (for example, Res or RBs) of the SS 600 block can be allocated to load a PSS 602, an SSS 604, and a PBCH 606. Some resources of the SS block can be allocated to a reference signal demodulation (DMRS) associated with PBCH. For example, some Res of the symbols where PBCH 606 is located can be allocated to associated DMRS 610 or similar. In some aspects of the disclosure, PBCH 606 covers a greater bandwidth (PBCH BW) than that of PSS and / or SSS. In one example, the PBCH may have a bandwidth of 240 tons (for example, subcarriers 0, 1, ...
239), and the PSS / SSS can have a bandwidth of 127 tones (for example, subcarriers 56, 57, ... 182). In another example, the PBCH bandwidth can be twice as wide as the PSS / SSS bandwidth.
[00072] In 5G NR, PBCH channel estimation and demodulation can be performed using PSS / SSS and / or DMRS. The PSS and SSS are transmitted in the same SS 600 block as the PBCH and multiplexed in the time domain with the PBCH symbols. The DMRS is transmitted in the same symbol as the PBCH and multiplexed in the frequency domain. In this example, PBCH 606 occupies the second and fourth symbols, PSS 602 occupies the first symbol and SSS 604 occupies the third symbol. This specific SS 602 block configuration is merely an example. In other aspects of the disclosure, PSS, SSS and PBCH can be allocated to Res different from an SS block in other examples. That is, the sequence of PBCH, PSS and SSS may be different than this example and, in addition
Petition 870190101977, of 10/10/2019, p. 38/83
33/49 addition, it may appear different in the frequency domain.
[00073] When the programming entity transmits PSS and SSS in the same SS block as the PBCH, the receiving device can demodulate the PBCH based, at least in part, on the PSS and / or SSS. The PSS / SSS can be used as a reference signal for estimating and demodulating the PBCH channel. In this case, a dedicated DMRS can be used to provide at least channel estimation for the PBCH Res in the tones where the PSS / SSS is not transmitted. In some aspects of the disclosure, the PSS / SSS can be transmitted from one port (for example, port P0), while the PBCH can be transmitted from two ports (for example, a common port P0 with PSS / SSS and an additional port Pl ). In this case, a dedicated DMRS may be required to provide channel estimation for at least Pl port transmission.
[00074] In the example described in relation to figure 6, as the PSS and SSS do not use all available bandwidth in the SS 600 block, some or all of the unused / unallocated resources 612 (for example, Res) can be used to upload additional information or supplemental channels. Some non-limiting examples of supplementary channels are a sincere signal. Tertiary (TSS) for signaling an SS block time index, a beam reference signal (BRS) for beam refinement, an activation radio signal or the like to support EU energy savings, a common search space PDCCH to signal a programming concession of PDSCH resources that carry minimum system information block (MSIB) information (for example, information indicating a location on a partition or RB where a minimum set of SIBs needed for
Petition 870190101977, of 10/10/2019, p. 39/83
34/49 channel access can be located), a paging signal / channel, etc. In another example, the supplementary channel can be a supplementary PBCH. In a specific example, the programming entity can reduce the overhead master information block (MIB) to signal a common search space configuration by using the reallocated Res to transmit the MIB information using the supplementary channel, etc.
[00075] In some examples, some or all of the available Res can be reallocated to transmit an additional signal or channel. For example, a supplementary channel can be multiplexed by frequency division (FDM) with the SSS, while the portion of the available Res 810 on the same symbol as the PSS can remain unused. That is, the nature of the PSS may be such that its information may be degraded if an additional channel is FDM with the PSS.
[00076] Figure 7 is a diagram illustrating an exemplifying SS block 700 according to some aspects of the disclosure. The SS 700 block has a PSS 702, an SSS 704, and a PBCH 706 similar to that of the SS 600 block described above. A DMRS associated with PBCH 706 is not shown in figure 7 for simplicity. In this example, the programming entity can allocate unused resources in the third symbol to a supplementary channel (for example, supplementary PBCH 708) to improve and / or extend link coverage. In this case, supplemental PBCH 708 and SSS 704 are multiplexed using FDM in the same location as the symbol. The supplementary PBCH can improve the link budget and / or coverage of PBCH by transmitting more repetition of PBCH payload encoded bits (for example, MIB). The supplementary PBCH 7 08 and PBCH
Petition 870190101977, of 10/10/2019, p. 40/83
35/49
706 can be encoded together so that they are linked from the channel encoding perspective. In one example, the encoded bits are repeated and mapped to the PBCH. The supplementary PBCH carries additional repetition of the encoded bits of the PBCH. To improve the link budget, the coded bits and their repetitions are additionally mapped to the supplementary PBCH. For example, the PBCH and supplementary PBCH data streams can be multiplexed and fed to a joint encoder. Joint encoding of the supplementary PBCH 708 and PBCH 706 can include one or more channel encoding, error correction encoding, mixing, modulation, layer mapping and precoding to generate OFDM symbols. In some aspects of the disclosure, the supplemental PBCH 708 and PBCH 706 can use the same channel coding and modulation scheme.
[00077] In some aspects of the disclosure, the programming entity can use the same transmission configuration (Tx) to transmit the supplementary PBCH 708 and PBCH 706 in the same SS block. Using the same TX configuration can simplify the receiver design. A TX configuration refers to a certain combination of transmission schemes. For example, a transmitting device can use the same antenna port configuration, the same beamforming configuration, and / or the same transmission diversity scheme to transmit the supplementary PBCH and PBCH that are encoded together and mapped to OFDM symbols many different. In some examples, the transmitting device may use the same numerology (for example, subcarrier spacing and cyclic prefix) to transmit the PBCH and
Petition 870190101977, of 10/10/2019, p. 41/83
36/49
Supplementary PBCH.
[00078] Figure 8 is a diagram illustrating another example SS block 800 according to some aspects of the relationship. The SS 800 block has a PSS 802, an SSS 804, and a PBCH 806 similar to those of the SS 600 and 700 blocks described above. In this example, the programming entity can allocate unused resources in the first and third symbols to a supplementary channel (for example, a supplementary PBCH 808) to improve and / or extend link coverage. In this case, the supplementary PBCH 808 is multiplexed in frequency with the PSS 802 and SSS 804. The programming entity can jointly encode the supplementary PBCH 808 and PBCH 806, and use the same channel encoding and modulation scheme for its transmission. In addition, the programming entity can use the same Tx configuration to transmit the supplementary PBCH and PBCH in the same SS block.
[00079] In some aspects of the disclosure, the supplemental signal channel loaded into the available Res can be at least partially used to load DMRS. In other examples, the DMRS loaded with the PBCH symbol can also be used as a demodulation reference signal for at least a part of the supplementary channel / signal. When the DMRS associated with the PBCH is used to demodulate the supplementary channel / signal, the transmitting device can indicate such a case to the UE through MIB, SIB or RRC signaling. For example, in a scenario where a UE is stationary or moving slowly, DMRS-based channel demodulation into a different symbol, which carries the PBCH, may be suitable for
Petition 870190101977, of 10/10/2019, p. 42/83
37/49 demodulate the supplementary channel / signal. However, in a scenario where a UE is moving fast, such as on a train or car, demodulation of the supplemental channel / signal may benefit from having a DMRS on the same symbol as that supplemental channel / signal. In some instances, such use of DMRS for PBCH may be preconfigured and no explicit signaling for its use by the channel / supplementary signal may be necessary.
[00080] Referring again to figure 6, in one aspect of the disclosure some frequency-time resources 612 may remain unused or unallocated. In this example, the transmit power available for these unused or unallocated resources (for example, Res) can be used to boost or increase the PSS and / or SSS Tx power level. In one example, the programming entity can reinforce (that is, increase) the PSx / SSS Tx power level by 3dB or any desired value, limited by the available Tx power. That is, the power applied to Res that loads the PSS / SSS can be increased (that is, reinforced) by a predetermined amount (for example, 3dB) in relation to a nominal level or default value used for Res in the same RB or partition . As an UE can use PSS / SSS as DMRS to decode or demodulate the PBCH, the programming entity can inform the UE about power boost if applied. For example, the programming entity can use RRC signaling or downlink control information (DCI) to inform the UE about the PSS / SSS power boost. When power boost is applied to the PSS / SSS, the programming entity needs to consider the power of the PBCH. In one example, when the PBCH
Petition 870190101977, of 10/10/2019, p. 43/83
38/49 is transmitted at its nominal power (that is, without reinforcement), the PSS / SSS can be reinforced by x dB. When the PBCH power is already increased by y dB, the transmitting device can reinforce the PSS / SSS power by x + y dB so that the power difference between the PBCH and PSS / SSS can be maintained. The programming entity can indicate the enhanced PSS and / or SSS through system information (for example, minimum remaining system information (RMSI) or Other system information (OSI)) or resource control signaling (RRC).
[00081] Figures 9 and 10 are diagrams illustrating additional exemplifying SS block designs according to some aspects of the disclosure. With reference to figure 9, an SS 900 block includes a PBCH 902 in the first and fourth symbols, a PSS 904 in the second symbol, and an SSS 906 in the third symbol. Some features of frequency 908 in the second and third symbols are available for relocation as described above in relation to figures 6-8. With reference to figure 10, an SS 1000 block includes a PBCH 1002 in the first and fourth symbols, a PSS 1004 in the second symbol and an SSS 106 in the third symbol. Some frequency-time features 1008 in the second and third symbols are available for reallocation as described above in relation to figures 6-8.
[00082] Figure 11 is a block diagram illustrating an example of a hardware implementation for a programming entity 1100 employing a processing system 1114. For example, programming entity 1100 can be user equipment (UE) as illustrated in any one or more of Figures 1 and / or 2. In another
Petition 870190101977, of 10/10/2019, p. 44/83
39/49 example, programming entity 1100 can be a
station base how illustrated in any one or more of figures 1 and / or 2. [00083] THE entity programming 1100 can to be implemented with one system processing 1114 what includes one or more proces 1104 users. Examples in
1104 processors include microprocessors, microcontrollers, digital signal processors (DSPs), field programmable port arrangements (FPGAs), programmable logic devices (PLDs), state machines, gated logic, discrete hardware circuits and other suitable hardware configured for perform the various features described in all of this disclosure. In several examples, the programming entity 1100 can be configured to perform any one or more of the functions described here. That is, processor 1104, as used in a programming entity 1100, can be used to implement any one or more of the processes and procedures described in relation to figures 6-10 and 12.
[00084] In this example, processing system 1114 can be implemented with a bus architecture, generally represented by bus 1102. Bus 1102 can include any number of interconnecting buses and bridges depending on the specific application of processing system 1114 and design limitations in general. The 1102 bus communicates several circuits together including one or more processors (generally represented by the 1104 processor), a 1105 memory, and computer-readable media (generally represented by the computer-readable media
Petition 870190101977, of 10/10/2019, p. 45/83
40/49
1106). The 1102 bus can also connect several other circuits such as timing sources, peripherals, voltage regulators, and power management circuits, which are well known in the art and, therefore, will not be described further. A bus interface 1108 provides an interface between bus 1102 and a transceiver 1110. Transceiver 1110 provides an interface or means of communication for communicating with various other aspects through a transmission medium. Depending on the nature of the device, an 1112 user interface (for example, key pad, display, speaker, microphone, joystick) can also be provided. Of course, such an 1112 user interface is optional, and can be omitted in some examples, such as a base station.
[00085] In some aspects of the disclosure, processor 1104 may include circuitry (for example, a processing circuit 1140, a communication circuit 1142, and an encoding circuit 1144) configured for various functions, including, for example, communication with a programmed entity using a synchronization signal block. For example, the circuitry can be configured to implement one or more of the functions described in relation to figure 12.
