CROSS REFERENCE TO CORRELATE ORDER (S) [0001] This request claims the benefit of
U.S. Provisional Application, Serial No. 62 / 462,872, entitled USE OF SYNCHRONIZATION SIGNAL BLOCK INDEX IN NEW RADIO and filed on February 23, 2017, and U.S. Patent Application.
15 / 802.398, entitled USE OF THE SYNCHRONIZATION SIGNAL BLOCK INDEX IN A NEW RADIO, and deposited on November 2, 2017, which are expressly incorporated herein by reference in their entirety.
FUNDAMENTALS
Technical Field [0002] The present disclosure generally refers to communication systems and, more specifically, to the use of an index of synchronization signal blocks for scrambling.
Introduction [0003] Wireless communication systems are widely deployed to provide various telecommunication services, such as telephony, video, data, messages and broadcasts. Typical wireless communication systems can use multiple access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple access technologies include code division multiple access systems (CDMA), time division multiple access systems (TDMA), frequency division multiple access systems
Petition 870190080886, of 8/20/2019, p. 5/84
2/58 (FDMA), orthogonal frequency division multiple access systems (OFDMA), single carrier frequency division multiple access systems (SC-FDMA) and time division synchronous code division multiple access systems (TD-SCDMA).
[0004] These multiple access technologies have been adopted in several telecommunication standards to provide a common protocol that allows different wireless devices to communicate at a municipal, national, regional and even global level. An example of a telecommunications standard is the New Radio 5G (NR). NR 5G is part of a continued evolution of mobile broadband promulgated by the Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (for example, with Internet of Things (IoT)) and other requirements. Some aspects of NR 5G may be based on the 4G Long Term Evolution (LTE) standard. There is a need for further improvements in NR 5G technology. These improvements may also be applicable to other multiple access technologies and telecommunication standards that use these technologies.
SUMMARY [0005] The following is a simplified summary of one or more aspects, in order to obtain a basic understanding of such aspects. This summary is not an extensive overview of all aspects covered and is not intended to identify key or critical elements of all aspects or to outline the scope of any or all aspects. Its sole purpose is
Petition 870190080886, of 8/20/2019, p. 6/84
3/58 to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later.

description of various configurations and is not intended to represent the only configurations in which the concepts described here can be put into practice. The detailed description includes specific details for the purpose of providing a complete understanding of several concepts. However, it will be evident to those skilled in the art that these concepts can be put into practice without these

7/58 specific details. In some cases, well-known structures and components are shown in the form of a block diagram to avoid obscuring such concepts.
[0029] Several aspects of telecommunication systems will now be presented with reference to different devices and methods. These devices and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as elements). These elements can be implemented using electronic hardware, computer software or any combination of them. Whether these elements are implemented as hardware or software, depends on the specific application and design restrictions imposed on the system as a whole.
[0030] As an example, an element, or any part of an element, or any combination of elements can be implemented as a processing system that includes one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, systems over a chip (SoC), field programmable port arrays (FPGAs), programmable logic devices (PLDs), state machines, port logic, discrete hardware circuits and other suitable hardware configured to perform the
Petition 870190080886, of 8/20/2019, p. 11/84
8/58 several features described throughout this disclosure. One or more processors in the processing system can run software. Software should be interpreted widely to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executables , execution topics, procedures, functions, etc., whether referring to software, firmware, middleware, microcode, hardware description language or others.
[0031] Therefore, in one or more exemplary modalities, the functions described can be implemented in hardware, software, or any combination thereof. If implemented in software, functions can be stored or encoded as one or more instructions or code in a computer-readable medium. The computer-readable medium includes computer storage media. The storage medium can be any available medium that can be accessed by a computer. For example, and not by way of limitation, these computer-readable media may comprise a random access memory (RAM), a read-only memory (ROM), an electrically erasable programmable ROM (EEPROM), optical disk storage, storage magnetic disk, other magnetic storage devices, combinations of the types of computer-readable media mentioned above, or any other medium that can be used to store executable computer code on
Petition 870190080886, of 8/20/2019, p. 12/84
9/58 form of instructions or data structures that can be accessed by a computer.
[0032] Figure 1 is a diagram illustrating an example of a wireless communications system and an access network 100. The wireless communications system (also referred to as a wireless extended network (WWAN)) includes base stations 102 , UEs 104 and an Evolved Packet Core (EPC) 160. Base stations 102 may include macro-cells (high energy cellular base station) and / or small cells (low energy cellular base station). The macrocells include base stations. Small cells include femto-cells, pico-cells and micro-cells.
[0033] Base stations 102 (collectively referred to as the Evolved Terrestrial Radio Access Network (EUTRAN) of the Universal Mobile Telecommunications System (UMTS)) interface with EPC 160 through 132 return links (for example, Sl interface) . In addition to other functions, base stations 102 can perform one or more of the following functions: user data transfer, radio channel encryption and decryption, integrity protection, head compression, mobility control functions (such as , handover, dual connectivity), inter-cell interference coordination, connection configuration and release, load balancing, distribution for non-access statement (NAS) messages, NAS node selection, synchronization, radio-access network sharing ( RAN), Broadcast / Multicast Multimedia Service (MBMS), equipment and subscriber tracking, RAN information management (RIM), paging, positioning and message delivery
Petition 870190080886, of 8/20/2019, p. 13/84
10/58 notice. Base stations 102 can communicate directly or indirectly (as, for example, via EPC 160) with each other over return links 134 (for example, interface X2). Return links 134 can be wired or wireless.
[0034] Base stations 102 can communicate wirelessly with UE 104. Each base station 102 can provide communication coverage for a respective geographic coverage area 110. There may be overlapping geographic coverage areas 110. For example, the small cell 102 'may have a coverage area 110' that overlaps the coverage area 110 of one or more macro base stations 102. A network that includes both small cells and macro cells may be known as a heterogeneous network. A heterogeneous network can also include Domestic Evolved B Nodes (eNBs) (HeNBs), which can provide service to a restricted group known as a closed subscriber group (CSG). Communication links 120 between base stations 102 and UEs 104 may include uplink transmission (UL) (also referred to as reverse link) from UE 104 to base station 102 and / or downlink (DL) transmissions ( also referred to as reverse link) from a base station 102 to a UE 104. Communication links 120 can use multiple input and multiple output antenna technology (MIMO), which includes spatial multiplexing, beam formation and / or diversity transmission. Communication links can be through one or more carriers. Base stations 102 / UEs 104 can use spectrum up to Y MHz (such as 5, 10, 15, 20 MHz) bandwidth per carrier
Petition 870190080886, of 8/20/2019, p. 14/84
11/58 allocated in a carrier aggregation of up to a total of Yx MHz (x component carriers) used for transmission in each direction. The carriers may or may not be adjacent to each other. The allocation of carriers can be asymmetric with respect to DL and UL (for example, more or less carriers can be allocated to DL than to UL). Component carriers can include a primary component carrier and one or more secondary component carriers. A primary component carrier can be referred to as a primary cell (PCell) and a secondary component carrier can be referred to as a secondary cell (SCell).
[0035] Certain UEs 104 can communicate with each other using the device-to-device communication link 192 (D2D). The D2D communication link 192 can use the DL / UL WWAN spectrum. The D2D communication link 192 can use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a shared physical sidelink channel (PSSCH) and a physical sidelink control channel (PSCCH). D2D communication can be through several D2D wireless communication systems, such as, for example, FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11, LTE or NR standard.
[0036] The wireless communication system may additionally include a Wi-Fi access point (AP) 150 in communication with Wi-Fi stations (STAs) 152 via communication links 154 in an unlicensed frequency spectrum of 5 GHz When communicating over a spectrum of
Petition 870190080886, of 8/20/2019, p. 15/84
12/58 frequency is not licensed, STAs 152 / AP 150 can perform a channel release assessment (CCA) prior to
communication mode The to determine if O channel is available.[0037] THE small cell 1 02 'can run on a spectrum of frequency licensed and / or not licensed. When it works in one spectrum in frequency not licensed, the cell small 102 ' can use NR and
use the same 5 GHz unlicensed frequency spectrum used by the Wi-Fi AP 150. The small cell 102 ', which uses NR in an unlicensed frequency spectrum, can boost coverage and / or increase the capacity of the access network .
[0038] gNóB (gNB) 180 can work at millimeter wave frequencies (mmW) and / or near-mmW frequencies in communication with UE 104. When gNB 180 works at mmW or near mmW frequencies, gNB 180 can be referred to as an mmW base station. The extremely high frequency (EHF) is part of the RE in the electromagnetic spectrum. The EHF has a range of 30 GHz to 300 GHz and a wavelength between 1 mm and 10 mm. The radio waves in the band can be referred to as millimeter waves. Almost mmW can extend up to a frequency of 3 GHz with a wavelength of 100 mm. The super high frequency band (SHF) extends between 3 GHz and 30 GHz, also known as centimeter wave. Communications using the mmW / almost mmW radio frequency band have an extremely high loss of travel and a short range. The base station mmWM 180 can use beamforming 184 with UE 104
Petition 870190080886, of 8/20/2019, p. 16/84
13/58 to compensate for extremely high travel loss and short reach.
[0039] EPC 160 may include a Mobility Management Entity (MME) 162, other MMEs 164, a Server Gateway 166, a Multicast Broadcast Multimedia Service Gateway (MBMS) 168, a Multicast Broadcast Service Center (BM -SC) 170 and a Packet Data Network Gateway (PDN) 172. MME 162 may be in communication with a Domestic Subscriber Server (HSS) 174. MME 162 is the control node that processes signaling between the UEs 104 and EPC 160. Generally, MME 162 provides carrier and connection management. All user Internet Protocol (IP) packets are transferred via Gateway Server 166, which is itself connected to PDN Gateway 172. PDN Gateway 172 provides UE IP address allocation as well as other functions. PDN Gateway 172 and BM-SC 170 are connected to IP Services 176. IP Services 176 can include the Internet, an intranet, an IP Multimedia Subsystem (IMS), a Streaming PS Service and / or other services IP. The BM-SC 170 can provide functions for the provision and delivery of MBMS user services. The BM-SC 170 can serve as an entry point for transmitting MBMS from a content provider, can be used to authorize and start MBMS Carrier Services within a public terrestrial mobile network (PLMN) and can be used to schedule transmissions of MBMS MBMS. The MBMS Gateway 168 can be used to distribute MBMS traffic to base stations 102 belonging to a Single Multicast Broadcast Frequency Network (MBSFN) area that broadcasts
Petition 870190080886, of 8/20/2019, p. 17/84
14/58 a specific service and may be responsible for session management (start / stop) and for collecting eMBMS related billing information.
[0040] The base station can also be referred to as a gNB, Node B, evolved Node B (eNB), an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a set basic services (BSS), a set of extended services (ESS) or some other suitable terminology. Base station 102 provides an access point for EPC 160 for an UE 104. Examples of UE 104 include a cell phone, a smart phone, a login protocol phone (SIP), a laptop, a personal digital assistant (PDA), a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (for example, MP3 player), a camera, a game console, a tablet, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small kitchen appliance, a health care device, an implant, a monitor or any other similarly functioning device. Some of the UEs 104 can be referred to as loT devices (such as, for example, parking meter, gas pump, toaster, vehicles, cardiac monitor, etc.). UE 104 can also be referred to as a station, mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, a mobile subscriber, one
Petition 870190080886, of 8/20/2019, p. 18/84
15/58 access terminal, a mobile terminal, a wireless terminal, a remote terminal, a telephone set, a user agent, a mobile client, a client or some other suitable terminology.
[0041] Referring again to Figure 1, in certain respects the UE 104 / base station 180 can be configured to scramble / unscramble information based on an SS block index (or any part or subset of the SS block index) ), where the SS block indexes a specific SS block within an SS burst within a set of SS bursts (198). Information can be scrambled based on the SS block index before it is transmitted and / or it can be scrambled based on the SS block index after it is received.
[0042] Figure 2A is a diagram 200 that illustrates an example of a DL subframe within an NR / 5G frame structure. Figure 2B is a diagram 230 that illustrates an example of channels within a DL subframe. Figure 2C is a diagram 250 that illustrates an example of a UL subframe within an NR / 5G frame structure. Figure 2D is a diagram 280 that illustrates an example of channels within a UL subframe. The NR / 5G frame structure can be the FDD where, for a specific set of subcarriers (carrier system bandwidth), subframes within the set of subcarriers are dedicated to either DL or UL, or they can be the TDD in whereas, for a specific set of subcarriers (carrier system bandwidth), subframes within the set of subcarriers are dedicated to both DL and UL. We
Petition 870190080886, of 8/20/2019, p. 19/84
16/58 examples provided by Figures 2A, 2C, the frame structure NR / 5G is assumed to be TDD, with subframe 4 being a subframe DL and subframe 7 being a subframe UL. Although subframe 4 is illustrated as providing only DL and subframe 7 illustrated as providing only UL, any specific subframe can be divided into the different subsets that provide both UL and DL. Note that the description below also applies to an NR / 5G frame structure which is FDD.
[0043] Other wireless communication technologies may have a different frame structure and / or different channels. One frame (10 msec) can be divided into 10 subframes of equal size (1 msec). Each subframe can include one or more time partitions. Each partition can include 7 or 14 symbols, which depend on the configuration of the partition. For a partition configuration 0, each partition can include 14 symbols, and for a partition configuration 1, each partition can include 7 symbols. The number of partitions within a subframe is based on the partition configuration and numerology. For a partition configuration 0, different numerologies from 0 to 5 allow 1, 2, 4, 8, 16 and 32 partitions, respectively, per subframe. For a partition configuration 1, different numerologies from 0 to 2 allow 2, 4 and 8 partitions, respectively, per subframe. Subcarrier spacing and symbol length / duration are a function of numerology. The subcarrier spacing can be equal to 2 ^μ * 15 kKz, where μ is numerology 0-5. The length / duration of the symbol is inversely related to the spacing of the subcarrier. Figures 2A, 2C provide
Petition 870190080886, of 8/20/2019, p. 20/84
17/58 an example of partition configuration 1 with 7 symbols per partition and numerology 0 with 2 partitions per subframe. The spacing of the subcarrier is 15 kHz and the symbol duration is approximately 66.7 ps.
[0044] A resource grid can be used to represent the frame structure. Each time partition includes a resource block (RB) (also referred to as physical REs (PRBs)) that span 12 consecutive subcarriers. The resource grid is divided into several resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.
[0045] As shown in Figure 2A, some of the REs carry reference signals (pilot) (RS) to the UE (indicated as R). The RS may include reference signals of RS demodulation information (DMRS) and channel status (CSI-RS) for channel estimation in the UE. RS can also include RS beam measurement (BRS), RS beam refinement (BRRS) and RS phase noise tracking (PT-RS).
[0046] Figure 2B illustrates an example of several channels within a DL subframe of a frame. The physical control format indicator channel (PCFICH) is within the 0 symbol of partition 0 and carries a control format indicator (CFI) indicating whether the physical downlink control channel (PDCCH) occupies 1, 2 or 3 symbols (Figure 2B illustrates a PDCCH that occupies 3 symbols). The PDCCH carries downlink control information (DCI) within one or more control channel elements (CCEs), each CCE including nine RE groups (REGs), each REG including four consecutive REs in an OFDM symbol. A UE can be configured with an advanced UE-specific PDCCH (ePDCCH)
Petition 870190080886, of 8/20/2019, p. 21/84
18/58 which also carries DCI. The ePDCCH can have 2, 4 or 8 pairs of RB (figure 2B shows two pairs of RB, each subset including a pair of RBs). The hybrid auto repeat request (ARQ) indicator channel (HARQ) (PHICH) is also within the 0 symbol of partition 0 and carries the HARQ (HI) indicator that indicates acknowledgment of HARQ (ACK) / ACK negative recognition ( NACK) based on the shared physical uplink channel (PUSCH). The primary synchronization channel (PSCH) can be within the symbol 6 of partition 0 within subframes 0 and 5 of a frame. The PSCH carries a primary synchronization signal (PSS) which is used by a UE 104 to determine the timing of the subframe / symbol and an identity of the physical layer. The secondary synchronization channel (SSCH) can be within the symbol 5 of partition 0 within subframes 0 and 5 of a frame. The SSCH carries a secondary synchronization signal (SSS) that is used by a UE to determine a physical layer cell identity and radio frame timing group number. Based on the physical layer identity and the physical layer cell identity group number, the UE can determine a physical cell identifier (PCI). Based on the PCI, the UE can determine the locations of the aforementioned DLRS. The physical broadcast channel (PBCH), which carries a master information block (MIB), can be logically grouped with the PSCH and SSCH to form a PBCH / (SS) block synchronization signal. The MIB provides a number of RBs in the DL system bandwidth, a PHICH configuration and a number of system frames (SEN). The physical downlink shared channel (PDSCH) carries user data,
Petition 870190080886, of 8/20/2019, p. 22/84
19/58 broadcast system not transmitted through the PBCH, such as system information blocks (STBs) and paging messages.
[0047] As illustrated in Figure 2C, some of the REs carry demodulation reference signals (DMRS) for channel estimation at the base station. The UE can, in addition, transmit audible reference signals (SRS) on the last symbol of a subframe. The SRS can have an alveolar structure and a UE can transmit SRS in one of the combs. The SRS can be used by a base station to estimate channel quality to allow frequency-dependent programming on the UL.
[0048] Figure 2D illustrates an example of several channels within a UL subframe of a frame. A physical random access channel (PRACH) can be within one or more subframes within a frame based on the PRACH configuration. PRACH can include six consecutive pairs of RBs within a subframe. PRACH allows the UE to perform initial access to the system and obtain UL synchronization. A physical uplink control channel (PUCCH) can be located on the edges of the UL system bandwidth. The PUCCH carries uplink control information (UCI), such as scheduling request, a channel quality indicator (CQI), a pre-coding matrix indicator (PMI), a rating indicator (RI) and feedback from HARQ ACK / NACK. The PUSCH carries data and can additionally be used to carry a storeroom condition report (BSR), an energy headroom report (PHR) and / or UCI.

20/58 [0049] Figure 3 is a block diagram of a base station 310 in communication with a UE 350 on an access network. In DL, IP packets from EPC 160 can be supplied to a 375 controller / processor. The 375 controller / processor implements layer 3 and layer 2 functionality. Layer 3 includes a radio resource control layer (RRC ) and layer 2 includes a packet data convergence protocol layer (PDCP), a radio link control layer (RLC) and a media access control layer (MAC). The 375 controller / processor provides RRC layer functionality associated with broadcasting system information (for example, MIB, STBs), RRC connection control (for example, RRC connection paging, RRC connection establishment, RRC connection modification and release of RRC connection) mobility of inter-radio access technology (RAT) and measurement configuration for the UE measurement report; PDCP layer functionality associated with header compression / decompression, security (encryption, decryption, integrity protection, integrity checking) and handover support functions; RLC layer functionality associated with the transfer of data units in upper layer packets (PDUs), error correction through ARQ, concatenation, segmentation and reassembly of RLC service data units (SDUs), re-segmentation of RLC data PDUs and re-ordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing MAC SDUs in transport blocks (TBs), demultiplexing MAC MACs
Petition 870190080886, of 8/20/2019, p. 24/84
21/58 from TBs, programming information report, error correction using HARQ, priority management and logical channel prioritization.
[0050] The transmit processor (TX) 316 and the receive processor (RX) 370 implement the layer 1 functionality associated with several signal processing functions. Layer 1, which includes a physical layer (PHY), can include error detection in transport channels, encoding / decoding of early error correction (FEC) and transport channels, interleaving, rate matching, mapping in physical channels, modulation / demodulation of physical channels and processing of MIMO antennas. The TX 316 processor handles mapping for signal constellations based on several modulation schemes (such as, for example, binary phase switching (BPSK) switching, quadrature switching (QPSK) switching, shift switching phase M (M-PSK), amplitude modulation by M square (M-QAM)). The coded and modulated symbols can then be divided into parallel streams. Each flow can then be mapped to an OFDM subcarrier, multiplexed with a reference signal (for example, pilot) in the time and / or frequency domain and then combining with each other using a Fast Inverse Fourier Transform (IFFT) to produce a physical channel that carries a stream of OFDM symbols in the time domain. The OFDM stream is spatially pre-coded to produce multiple spatial streams. Channel estimates from a 374 channel estimator can be used to determine the
Petition 870190080886, of 8/20/2019, p. 25/84
22/58 coding and modulation, as well as for spatial processing. The channel estimation can be derived from a reference condition and / or channel condition feedback signal transmitted by the UE 350. Each spatial flow can then be supplied to a different antenna 320 via a separate 318TX transmitter. Each 318TX transmitter can modulate an RF carrier with a corresponding spatial flow for transmission.
[0051] In the UE 350, each 354RX receiver receives a signal through its respective antenna 352. Each 354RX receiver retrieves the modulated information on an RF carrier and supplies the information to the receiving (RX) 356 processor. The TX 368 processor and the RX processor 356 implement the layer 1 functionality associated with various signal processing functions. The RX 356 processor can perform spatial processing on the information to retrieve any spatial streams destined for the UE 350. If multiple spatial streams are destined for the UE 350, they can be combined by the RX 356 processor into a single OFDM symbol stream. The RX 356 processor then converts the OFDM symbol stream from the time domain to the frequency domain using a Fast Fourier Transform (FFT). The frequency domain signal comprises a separate OFDM symbol stream for each OFDM signal subcarrier. The symbols on each subcarrier, and the reference signal, are retrieved and demodulated by determining the most likely signal constellation points transmitted by base station 310. These flexible decisions can be based on channel estimates
Petition 870190080886, of 8/20/2019, p. 26/84
23/58 computed by channel estimator 358. Flexible decisions are then decoded and deinterleaved to retrieve the data and control signals that were originally transmitted by base station 310 on the physical channel. The data and control signals are then supplied to the 359 controller / processor, which implements layer 3 and layer 2 functionality.
[0052] The 359 controller / processor can be associated with a 360 memory that stores program codes and data. 360 memory can be referred to as a computer-readable medium. At UL, the 359 controller / processor provides de-multiplexing between transport and logical channels, packet reassembly, decryption, header decompression and control signal processing to retrieve IP packets from EPC 160. The 359 controller / processor also is responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.
[0053] Similar to the functionality described in connection with DL transmission by base station 310, the 359 controller / processor provides RRC layer functionality associated with the acquisition of system information (eg, MIB, STBs), RRC connections and reporting measurement; PDCP layer functionality associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functionality associated with the transfer of top layer PDUs, error correction via ARQ, concatenation, segmentation and reassembly of RLC SDUs, re-segmentation of RLC data PDUs
Petition 870190080886, of 8/20/2019, p. 27/84
24/58 and rearrangement of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs in TBs, demultiplexing of MAC SDUs from TBs, programming information reports, error correction through HARQ, priority handling and prioritization of logical channels.
[0054] Channel estimates derived by a 358 channel estimator from a reference or feedback signal transmitted by base station 310 can be used by the TX 368 processor to select the appropriate coding and modulation schemes and to facilitate spatial processing . The spatial streams generated by the TX 368 processor can be supplied to different antennas 352 through separate 354TX transmitters. Each 354TX transmitter can modulate an RF carrier with a corresponding spatial flow for transmission.
[0055] The UL transmission is processed at base station 310 in a similar manner to that described in connection with the receiver function on UE 350. Each 318RX receiver receives a signal through its respective antenna 320. Each 318RX receiver retrieves the modulated information on an RF carrier and provides the information for an RX 370 processor.
[0056] The 375 controller / processor can be associated with a 376 memory that stores program codes and data. Memory 376 can be referred to as a computer-readable medium. At UL, the 375 controller / processor provides demultiplexing between transport and logic channels, reassembly of
Petition 870190080886, of 8/20/2019, p. 28/84
25/58 packets, decryption, unpacking of headers, processing control signals to retrieve IP packets from the UE 350. IP packets from the 375 controller / processor can be supplied to EPC 160. The 375 controller / processor is also responsible by detecting errors using an ACK and / or NACK protocol to support HARQ operations.
[0057] Figure 4 is a diagram 400 illustrating a base station 402 in communication with a UE 404. With reference to Figure 4, when UE 404 connects, UE 404 searches for a nearby NR network. UE 404 discovers base station 402, which belongs to an NR network. Base station 402 transmits an SS block that includes PSS, SSS and PBCH (which includes MIB) periodically in different transmission directions 402a-402h. UE 404 receives transmission 402e which includes PSS, SSS and PBCH. Based on the received SS block, the UE 404 synchronizes with the NR network and encapsulates on a cell associated with the base station 402.
[0058] As discussed above, PSS, SSS, and PBCH can be transmitted within an SS block. Each SS block has a corresponding SS block index (also referred to as SS / PBCH block index) indicated in Figure 4 as one of 0, 1, ..., n-1. PSS, SSS and PBCH can be multiplexed by time division and / or multiplexed by frequency division with the SS block (Figure 4 shows the PSS, SSS and PBCH multiplexed by time division within an SS block) . Although Figure 4 shows the PSS, SSS and PBCH as consecutive in time, the PSS, SSS and PBCH can be non-consecutive in time and, therefore, can be spaced from one to another by
Petition 870190080886, of 8/20/2019, p. 29/84
26/58 one or more partitions / symbols (that is, they may not be adjacent to each other in time). The SS block can include other signals / channels and therefore other signals / channels in addition to PSS, SSS and PBCH can be multiplexed in the SS block. One or multiple SS blocks make a burst of SS. The number n of SS blocks in an SS burst can vary. SS blocks may or may not be consecutive with respect to the corresponding SS block index. The SS blocks within an SS burst may or may not be the same. One or multiple bursts of SS make a set of bursts of SS. The periodicity (period F) of SS bursts and the number of SS bursts in a set of SS bursts may vary. The number of SS bursts within a set of SS bursts is finite. The transmission of SS burst sets can be periodic or aperiodic.
[0059] Figure 5A is a diagram 500 that illustrates an example of an SS burst. Figure 5B is a diagram 550 that illustrates an example of SS bursts for different frequency bands / carriers. Figure 6A is a diagram 600 that illustrates a first example of a set of SS bursts. Figure 6B is a diagram 650 that illustrates a second example of a set of SS bursts. As shown in diagram 500 of Figure 5A, an SS burst includes a plurality of SS blocks that correspond to the SS block indices 0, 1, ..., 7. A subset 502 of the SS blocks (see indices 2, 5, in this example) can be pre-configured in such a way that it can be turned off (i.e., not transmitted) to allow the transmission of a UL control block. As illustrated
Petition 870190080886, of 8/20/2019, p. 30/84
27/58 in diagram 550 of Figure 5B, different bands can have different SS burst configurations. For example, in band X, an SS burst can include SS blocks 0, 7, with SS blocks 2, being pre-configured for on / off to allow the transmission of an UL control block. For another example, in band Y, a burst of SS may include SS blocks 0, 1, 3, 4, 6, 7 with SS blocks 1, 4, 7 being preconfigured on / off to allow transmission of a UL control block. The illustrated SS burst can be a blade. ^the SS burst within a SS burst set. As illustrated in diagram 600 of Figure 6A, in a first example, a set of SS bursts may include K different SS bursts 0, 1, ..., Kl. The length of time for the SS burst set can be N * 10 msec, where N is an integer. With reference to Figure 6B, the periodicity (period Pi) of an SS burst in a set of SS bursts occurs with the frequency with which an SS burst is transmitted in a set of SS bursts *. The periodicity of the beam scan (period P2) occurs with the frequency with which an SS burst beam scan is repeated in a set of SS bursts. A UE can use repetitive SS bursts in a set of SS bursts to filter a received reference signal strength (RSRP) over time for the same beam direction and / or to train sub-arrays. In the example in Figure 6B, the set of SS bursts has a time length of 80 msec, the periodicity Ργ of the SS burst is 20 msec and the P2 periodicity of the beam scan is 40 msec.
Petition 870190080886, of 8/20/2019, p. 31/84
28/58 [0060] As discussed above, the SS block index can be used to indicate an SS block within an SS burst or within a set of SS bursts. When the SS block index is used to indicate an SS block within an SS burst, the SS bursts may have an SS burst index to indicate the specific SS burst within a set of SS bursts. As such, an SS block index can indicate an SS block within an SS burst within a set of SS bursts (for example, SS block indexes are 0, 1, ..., n * Kl for SS blocks in an SS burst set where there are n SS blocks per SS burst and K SS burst in an SS burst set), or the combination of an SS block index and an SS index bursts of SS can indicate an SS block within an SS burst within a set of SS bursts (for example, SS block indices are 0, 1, ..., n-1 for SS blocks in each set of SS bursts and the SS burst indexes are 0, 1, ..., Kl for SS bursts in a set of SS bursts). Here, the SS block index can refer to one or more indexes to indicate an SS block within an SS burst within a set of SS bursts. A mapping function can be used to map an index of SS blocks to a logical index. There may be a one-to-one mapping, with an SS block index mapped to a logical index. Alternatively, there may be a many-to-one mapping, with multiple SS block indexes mapped to a logical index.

29/58 [0061] Figure 7 is a diagram 700 that illustrates a first exemplary call flow diagram for an UE 702 and a base station 704. As shown in Figure 7, in 710, base station 704 determines an index of SS blocks associated with an SS block for transmission at 714. As discussed above, the SS block can include at least one from a PSS, an SSS or a PBCH. Base station 704 can determine the SS block index based on which SS block is being transmitted in a specific beam in a beam set (see Figure 4, 402a-402b). In 712, base station 704 scrambles information based on the given SS block index. Base station 704 can scramble the information by generating a scrambled sequence based on a sequence / scramble initialization that is based, at least in part, on the SS block index. For example, the scrambling initialization to scramble information can be based on any subset of the SS block index. For another example, the initialization of scrambling to scramble information can be based on either a subset of the SS block index or the cell ID of the base station. If the SS block index is m bits, the subset of the block index SS can include 1 for m bits. In one example, the subset of the SS block index can be X Less Significant Bits (LSBs) of the SS block index, where X can be 2 or 3. In an example, the SS block index is 6 bits ( for example, b5b4b3b2bib0) and the 3 LSBs (for example, b2bibo) of the SS block index are used to start the scramble to shuffle the
Petition 870190080886, of 8/20/2019, p. 33/84
30/58 information. Pre-scrambling information can be scrambled and / or non-scrambled, and scrambled based on the scrambled sequence generated. The information includes at least one of a reference signal, data, paging information, control information, broadcast information, or a CRC associated with the control information. In one configuration, the reference signal is at least one from CSI-RS, RS measurement (MRS) (also referred to as mobility RS), DMRS (for a PDCCH, PDSCH or PBCH), or PT-RS. In a configuration, the data is for a PDSCH, the paging information is for a paging channel (PCH), the control information is for a PDCCH, and the broadcast information is for a PBCH. When the information includes a scrambled CRC, the control information associated with the scrambled CRC may or may not be scrambled based on the SS block index.
[0062] For example, the initialization of the sequence for scrambling DMRS (for example, PBRS DMRS) can be based on the cell identification of base station 704 and the 3 LSBs of the SS block index. Specifically, the initialization for the PBCH DMRS can be c ± _n ± t ⁼ 2 (Íssb + 1) '([N _ID / 4] + 1) + 2 (Íssb + 1) + mod (N _ID / 4), where I _S sb is the SS block index and where for the maximum length L = 4, Í _S sb = Íssb + 4HF where HF = 0 in the first half frame of a radio frame and HF = 1 in the second half frame of a radio frame, and for the maximum length L = 8 and max L64, Íssb ⁼ Issb.
[0063] For another example, it is assumed that the information is broadcast information for a PBCH.

Before the coding / CRC process, base station 704 can shuffle the PBCH payload based on a shuffling sequence based on the cell ID of base station 704 (initialization of the
Ajcell scrambling Ci _n it = ID). As a result, after ο the coding / CRC process, base station 704 can scramble the scrambled PBCH based on a scrambled sequence that is based on this cell ID (initialization _N ceH of the scramble sequence = ID) and LSBs X of the index of SS blocks. The LSBs X bits of the SS block index are used to determine a non-overlapping sequential part of the sequence. The sequence can be a Gold sequence of length M (2x), where M is the number of bits to be shuffled. The sequence can be partitioned into the 2 non-overlapping parts. The LSBs X bits of the SS block index uniquely identify indexes for each non-overlapping part of the sequence, where X = 2 for the maximum length L = 4 and X = 3 for the maximum length L = 8 or 64. For X = 3 , the sequence index (for example, b2bibo) used for each PBCH can be as follows (where M is the number of bits to be scrambled):
(b2) (bl) (b0) Sequence index Used by each PBCH 0 0 0 0 ~ M-l 0 0 1 M ~ 2M-1 0 1 0 2 M ~ 3M-1 0 1 1 3M ~ 4M-1 1 0 0 4M ~ 5M-1 1 0 1 5 M ~ 6M-1 1 1 0 6M ~ 7M-1 1 1 1 7M ~ 8M-1

32/58 [0064] In 714, base station 704 transmits the SS block and the scrambled information to the UE 702. The SS block can include the scrambled information.
[0065] Base station 704 can use the SS block index to scramble a CRC when encoding a DL control payload. Base station 704 can use the scrambled CRC to transport a quasi-placement parameter (QCL) to a control channel without explicit signaling. Two antenna ports are said to be almost co-located if the properties of the channel over which a symbol in an antenna port is transported can be inferred from the channel over which a symbol in another antenna port is transported. QCL can support beam management functionality (which at least includes spatial parameters), frequency / time shift estimation functionality (which at least includes Doppler / delay parameters) and radio resource management functionality (which at least includes average gain). In the NR, all or a subset of DMRS antenna ports can be nearly placed. The transported QCL parameter can indicate QCL of reference signals associated with a pair of beams, which includes a beam associated with the control channel and the corresponding SS block index. By decoding the control channel and obtaining the SS block index, the UE 702 may be able to determine the QCL parameter associated with the SS block index. The control channel can include a common control channel (CCCH) and / or an EU-specific control channel (for example, the dedicated control channel (DCCH)). When UE 702 decodes such a channel,
Petition 870190080886, of 8/20/2019, p. 36/84
33/58 DL control, the UE 702 can use the decoded DL control information or can discard the decoded DL control information depending on whether the UE 702 is configured to receive such control information scrambled by the SS block index. With reference again to 710, base station 704 can determine an SS block to be used by UE 702 in association with reference signal QCL. In such a configuration, at 712, base station 704 can generate a CRC based on the control information to be transmitted to UE 7 02, and can scramble the CRC based on the determined SS block index. At 714, base station 704 can send control information and the CRC scrambled with the SS block index to UE 702.
[0066] In 714, UE 702 receives the SS block, which includes scrambled information based on the SS block index associated with the SS block.
[0067] In 716, UE 702 unscrambles the scrambled information based on the SS block index. UE 702 can unscramble the information itself based on the SS block index or it can unscramble a CRC associated with the information based on the SS block index. In the latter case, UE 702 can unscramble information based on the unscrambled CRC.
[0068] When scrambled information 714, which includes a scrambled CRC based on an SS block index, UE 702 can unscramble the CRC based on the SS block index and decode the received control information based on the CRC unscrambled (for example, decoding the received control information,
Petition 870190080886, of 8/20/2019, p. 37/84
34/58 generate a CRC based on the decoded control information and compare the generated CRC with the scrambled CRC to determine if the control information was successfully decoded / unscrambled). Therefore, in 718, the UE can determine a QCL parameter based on the SS block index used to unscramble the CRC. As discussed above, the QCL parameter can indicate QCL of reference signals associated with a pair of beams that includes a beam associated with the control channel and the corresponding SS block index.
[0069] Figure 8 is a diagram 800 illustrating a second exemplary call flow diagram for a UE and a base station. In 810, an UE 804 determines an SS block index associated with an SS block for reception. The SS block associated with the SS block index may have been received previously or may be received in the future. At 810, UE 804 can receive an uplink lease from base station 802, and can determine the SS block index based on the uplink lease. For example, if the UE receives a UL grant and an SS block on or associated with a beam, the UE may determine that the SS block index is the SS block index associated with the same beam as the grant of UL. Alternatively, UE 804 can receive, from base station 802, information indicating the SS block index and, at 810, it can determine the SS block index based on the received information.
[0070] In 812, UE 804 shuffles information based on the determined SS block index. The UE 804 can shuffle information by generating a
Petition 870190080886, of 8/20/2019, p. 38/84
35/58 scrambling sequence based on a sequence initialization that is based, at least in part, on the SS block index. Pre-scrambling information can be scrambled and / or non-scrambled and can be scrambled based on the scrambling sequence generated. The information includes at least one of the data, control information or a CRC associated with the control information. In a configuration, the data is for a RUSCH and the control information is for a PUCCH.
[0071] In 814, the UE 804 transmits the scrambled information to an 802 base station. When the scrambled information includes a CRC scrambled by the SS block index, the UE 804 can transmit the UL control information together with the index of UL SS blocks of scrambled CRC. The base station 802 receives, from the UE, the scrambled information based on the SS block index.
[0072] In 816, the base station 802 unscrambles the scrambled information based on the SS block index. When scrambled information includes a scrambled CRC based on an SS block index, the base station 802 can unscramble the CRC based on the SS block index and unscramble the UL control information received based on the scrambled CRC (for example, example, decode the UL control information received, generate a CRC based on the decoded UL control information, and compare the generated CRC with the scrambled CRC to determine whether the
Petition 870190080886, of 8/20/2019, p. 39/84
36/58 UL control were successfully decoded / unscrambled).
[0073] Figure 9 illustrates flowcharts 900, 950 of wireless communication methods from a base station. With respect to flow chart 900, at 904, a base station determines an SS block index associated with an SS block for transmission. As discussed above with reference to Figure 4, the SS block can include at least one from a PSS, an SSS or a PBCH. If the base station transmits n SS blocks within an SS burst and transmits K SS bursts within a set of SS bursts, the base station can determine the SS block index based on which SS block is being sent within an SS burst specifies a set of SS bursts. As such, the SS block index may be a function of n and K, as discussed above with reference to Figures 6A, 6B. In one example, the SS block index I _S sb can be a parameter within 0.1 n * Kl to indicate the SS block within an SS burst within a set of SS bursts. In another example, the SS block index I _S sb can be two parameters, with a first parameter between 0, 1, ..., n-1 (for example, S2S1S0C0, if 4 bits with n = 16) for indicate a specific SS block within an SS burst, and a second parameter between 0, 1, ..., Kl (for example, b5b4b.3jb2jb.ijbo, if 6 bits with K = 64) to indicate an SS burst specifies within a set of SS bursts.
[0074] In 906, the base station scrambles information based on at least part of the determined SS block index I _S sb. Information can
Petition 870190080886, of 8/20/2019, p. 40/84
37/58 be shuffled based on a subset (a part of) of the SS block index Issb, such as LSBs X of the SS block index. The information includes at least one of a reference signal, data, paging information, control information, broadcast information or a CRC associated with the control information. The reference signal can be at least one from CSI-RS, MRS, DMRS (for example, for a PDCCH, a PDSCH or a PBCH), or PTRS. In a configuration, the data is for a PDSCH, the paging information is for a PCH, the control information is for a PDCCH, and the broadcast information is for a PBCH. Using at least a portion of the determined SS block index I _S sb, the base station can scramble one or more of the various types of information. The base station can scramble the information by generating a scramble sequence based on a sequence initialization that is based, at least in part, on at least part of the SS block index. Pre-scrambling information can be coded and / or non-scrambled and can be scrambled based on the generated scramble sequence.
[0075] In a configuration, the scrambled information includes the scrambled CRC based at least on the SS block index part and the CRC is for the control information sent to the UE. In such a configuration, at 902, the base station can determine an SS block to be used by a UE in association with QCL of reference signals. Additionally, in 906, the base station can shuffle the CRC based on at least the SS block index part of the given SS block
Petition 870190080886, of 8/20/2019, p. 41/84
38/58 in 902 to be used by the UE in association with QCL of reference signals.
[0076] In 908, the base station transmits the SS block and the scrambled information. The scrambled information can be transmitted with (concurrently in time with) or without (not concurrently in time with) the SS block. For example, when the scrambled information is the PBCH, the scrambled PBCH is sent with the SS block. However, when the scrambled information is control information with a CRC, the control information scrambled with a CRC may not be transmitted concurrently in time with the SS block.
[0077] With respect to flowchart 950, at 952, a base station can send an uplink grant for information to a UE, where the uplink grant is associated with an SS block index. Alternatively, the base station can send the SS block index information to the UE which indicates an SS block index for scrambled information.
[0078] In 954, the base station receives, from the UE, the scrambled information based on at least part of the SS block index. The scrambled information includes at least one of data or control information. In a configuration, the data is for a PUSCH and the control information is for a PUCCH.
[0079] In 956, the base station scrambles the scrambled information based, at least, on the SS block index part. For example, the base station can receive information from the UE that is scrambled based on at least the part of the SS block index and can
Petition 870190080886, of 8/20/2019, p. 42/84
39/58 unscramble the information received based at least on the SS block index part. For another example, the base station can receive the information with a scrambled CRC based on at least the part of the SS block index. The base station can unscramble the CRC received from the UE, decode the information, generate a CRC based on the decoded information and compare the generated CRC with the scrambled CRC to determine whether the information received from the UE has been successfully decoded / unscrambled .
[0080] Figure 10 illustrates flowcharts 1000, 1050 of wireless communication methods of an UE. With respect to flowchart 1000, at 1002, a UE receives an SS block and scrambled information based on at least part of an SS block index associated with the SS block. As discussed with reference to Figure 4, the SS block can include at least one from a PSS, an SSS or a PBCH. The information includes at least one of a reference signal, data, paging information, control information, broadcast information, or a CRC associated with the control information. In one configuration, the reference signal is at least one from CSI-RS, MRS, DMRS (for example, for a PDCCH, a PDSCH or a PBCH), or PT-RS. In a configuration, the data is for a PDSCH, the paging information is for a PCH, the control information is for a PDCCH, and the broadcast information is for a PBCH.
[0081] In 1004, the UE decrypts the scrambled information based, at least, on the SS block index part. In a configuration, the information
Petition 870190080886, of 8/20/2019, p. 43/84
Scrambled 40/58 includes a scrambled CRC based at least on the SS block index part. In such a configuration, in 1004, the UE unscrambles the CRC based, at least, on the SS block index part, and decodes the control information received based on the unscrambled CRC.
[0082]
In the configuration where
UE unscrambles the CRC based on at least the part of the SS block index and decodes the control information received based on the unscrambled CRC in 1006, the UE can determine a QCL parameter based on at least the part of the SS block index used to unscramble the CRC.
[0083]
With respect to flow chart 1050, in
1052, a UE can receive an uplink lease from a base station. Alternatively, the UE may receive, from the base station, information indicating an SS block index.
[0084]
In 1054, the UE determines the SS block index associated with an SS block for reception. The UE can determine the SS block index based on the uplink grant, or otherwise, based on information indicating an SS block index.
[0085]
In 1056, the UE scrambles the information based on at least part of the determined SS block index. The information includes at least one of data or control information. In a configuration, the data is for a RUSCH, and the control information is for a PUCCH. The UE can scramble its own information and / or scramble a CRC associated with the information. The UE can
Petition 870190080886, of 8/20/2019, p. 44/84
41/58 shuffle the information by generating a shuffle sequence based on a sequence initialization that is based, at least in part, on at least part of the SS block index.
