BACKGROUND
[0002] The following relates, in general, to communication by wireless technology (wireless), and, more specifically, to reference signal schemes in wireless communications.
[0003] Wireless communication systems (wireless) are widely used to offer various types of communication content, such as voice, video, data packets, messaging, broadcast (broadcast), among others. These systems may be able to support communication with multiple users by sharing available system resources (for example,
example, time, frequency and power in streaming). Examples in such systems access multiple include systems in Access Multiple by Division in Code (CDMA), systems in Access Multiple by Division at the Time (TDMA), systems in Access Multiple o by Division Frequency
(FDMA) and Division Access Multiple Access systems
Orthogonal Frequency (OFDMA) (for example, a
Long Term Evolution (LTE), or a Nova Rádio system

2/113 (NR)).
[0004] In some examples, a wireless multiple access communication system may include a series of base stations, each simultaneously supporting communication for multiple communication devices, alternatively known as user equipment (UEs). In an LTE or LTE-Advanced (LTE-A) network, a set of one or more base stations can define an eNodeB (eNB). In other examples (for example, on an NR or 5G network), a multiple access communication system may include a series of intelligent radio heads (radio heads - RHs) in communication with a series of access node controllers (ANCs) ), where a set of one or more HRs, in communication with an ANC, defines a base station (for example, an eNB or gNB). A base station can communicate with a set of UEs on the downlink (DL) channels (for example, for transmissions from the base station to a UE) and on the uplink (UL) channels (for example, for transmissions in the sense from the UE to a base station).
[0005] Sometimes, a UE may need to perform an initial access procedure (or initial acquisition) to obtain access to a wireless network. As part of the initial access procedure, the UE may need to search for a synchronization channel transmitted by a network access device, such as a base station, on the wireless network. The UE can also obtain several items of system information, such as contained in a master information block (MIB) or one or more blocks of system information (for example, SIB1, SIB2, etc.) that can be

SUMMARY
[0006] The techniques described refer to improved methods, systems, devices or devices that support reference signal schemes in wireless communications. In general, the described techniques provide synchronization signal blocks (SS) in which synchronization signals and physical broadcast channel (PBCH) transmissions can be transmitted. In some cases, PBCH transmissions can be demodulated using SS transmissions, reference signal transmissions, or combinations thereof. In some examples, PBCH transmissions can be transmitted in a subset of SS block time resources (for example, in two symbols of an SS block), and synchronization signals (for example, the primary synchronization signal (PSS ) and the secondary sync signal (SSS)) can be transmitted in another subset of the SS block time resources.
[0007] In some cases, reference signals (for example, a demodulation reference signal (DMRS)) can be transmitted using tones within the PBCH time resources, and the locations of the tones can be selected to offer demodulation efficient using relatively transmission resources. In some cases, a bandwidth for PBCH transmissions may be greater than a bandwidth for SS transmissions, and DMRS may be transmitted at a higher density for parts of the PBCH transmission bandwidth that are outside the bandwidth. SS transmission band. In

4/113 In some cases, different DMRS tones can be used for different PBCH time resources.
[0008] In some cases, a DMRS waveform can be configured between PBCH time resources (for example, between two or more symbols that contain PBCH transmissions). In some examples, the same DMRS sequence can be used for each PBCH symbol, and each PBCH symbol can include the same number of DMRS tones. In other examples, PBCH symbols may include a subset of DMRS tones common between PBCH symbols and a subset of DMRS tones that are different between PBCH symbols. In such examples, ordinary DMRS tones may share the same DMRS sequence, and the other DMRS tones may have a different sequence. In still other examples, the DMRS waveforms for different symbols of PBCH transmissions can be completely different. In some examples, different DMRS sequences can be constructed by dividing a long base sequence between different PBCH time resources (for example, a long Zadoff-Chu sequence, m sequence, or cyclic shifts). In some examples, reference signal strings (for example, DMRS strings), tone locations, or combinations thereof, can be used to transmit one or more of identification information, timing information, configuration information, or any combination the same.

DETAILED DESCRIPTION
[0079] Wireless communications systems as described here can be configured to provide synchronization signal blocks (SS) in which synchronization signals and physical broadcast channel (PBCH) transmissions can be transmitted, to assist user equipment (UE) in the acquisition and initial communication with a base station. In some examples, PBCH transmissions can be transmitted in a subset of SS block time resources (for example, in two symbols of an SS block), and synchronization signals (for example, the primary synchronization signal (PSS ) and the secondary sync signal (SSS)) can be transmitted in another subset of the SS block time resources. In implementations that use millimeter wave (mmW) transmission frequencies, multiple SS blocks can be transmitted in different directions using beam scanning in an SS burst, and SS bursts can be transmitted periodically according to a burst set. of SS. In cases where a base station can transmit in an omnidirectional direction, an SS block can be transmitted periodically according to a configured periodicity.
[0080] In some cases, PBCH transmissions can be demodulated using SS transmissions, where the
Petition 870190100328, of 10/07/2019, p. 46/198
40/113 SS transmissions are used for channel estimation, which can allow an UE to demodulate PBCH transmissions. In some examples, PBCH transmissions may be transmitted using a higher frequency bandwidth than SS transmissions, in which case one or more reference signal transmissions (for example, demodulation reference signal transmissions (DMRS )) on PBCH transmissions can be useful to provide reliable demodulation of PBCH transmissions. In some examples, PBCH transmissions can be demodulated using reference signal transmissions, SS transmissions, or combinations thereof.
[0081] In some cases, reference signals (for example, DMRS) can be transmitted using tones within the PBCH time resources, and the locations of the tones can be selected in order to provide efficient demodulation using relatively transmission resources. In some cases, as indicated above, a bandwidth for PBCH transmissions can be greater than a bandwidth for SS transmissions, and DMRS can be transmitted at a higher density for parts of the PBCH transmission bandwidth that are outside the SS transmission bandwidth. In some cases, different DMRS tones can be used for different PBCH time resources.
[0082] In some cases, a DMRS waveform can be configured between PBCH time resources (for example, between two or more OFDM symbols that contain PBCH transmissions). In some examples, the same DMRS string can be used for each PBCH symbol, and each symbol
Petition 870190100328, of 10/07/2019, p. 47/198
41/113
PBCH can include the same number of DMRS tones. In other examples, PBCH symbols may include a subset of DMRS tones common between PBCH symbols and a subset of DMRS tones that are different between PBCH symbols. In such examples, ordinary DMRS tones may share the same DMRS sequence, and the other DMRS tones may have a different sequence. In still other examples, the DMRS waveforms for different symbols of PBCH transmissions can be completely different. In some examples, different DMRS sequences can be constructed by dividing a long base sequence between different PBCH time resources (for example, a long Zadoff-Chu sequence, m sequence, or cyclic shifts). In some examples, reference signal strings (for example, DMRS strings), tone locations, or combinations thereof, can be used to transmit one or more of identification information, timing information, configuration information, or any combination the same.
[0083] The aspects of the disclosure are initially described in the context of a wireless communications system. Examples of various channel configurations and resource allocation schemes are described. The aspects of the disclosure are further illustrated and described with reference to equipment diagrams, system diagrams and flowcharts that relate to reference signal schemes in wireless communications.
[0084] FIG. 1 illustrates an example of a wireless communications system 100 in accordance with various aspects of the present disclosure. The communications system
Petition 870190100328, of 10/07/2019, p. 48/198
42/113 wireless 100 includes base stations 105, UEs 115 and a core network 130. In some instances, wireless communications system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced network (LTE-A), or a Nova Rádio (NR) network. In some cases, the wireless communications system 100 can support enhanced broadband communications, ultra-reliable (for example, mission-critical) communications, low latency communications, and communications with low-cost, low-complexity devices. Base stations 105 and UEs 115 can be configured to use SS block with PBCH and SS transmissions that use different time resources (e.g., OFDM symbols) within an SS block.
[0085] Base stations 105 can communicate with UEs 115 wirelessly via one or more base station antennas. Each base station 105 can provide communication coverage for a respective geographic coverage area 110. The communication links 125 illustrated in the wireless communication system 100 can include uplink transmissions from an UE 115 to a base station 105, or transmissions downlink, from a base station 105 to a UE 115. Control information and data can be multiplexed on an uplink or downlink channel according to various techniques. Control information and data can be multiplexed on a downlink channel, for example, using time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. In some examples, the control information transmitted during an interval of time
Petition 870190100328, of 10/07/2019, p. 49/198
43/113 transmission (TTI) of a downlink channel can be distributed between different cascading control regions (for example, between a common control region and one or more UE-specific control regions).
[0086] UEs 115 can be dispersed throughout the wireless communication system 100, and each UE 115 can be fixed or mobile. A UE 115 can also be called a mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handset, user agent, mobile client, customer or any other suitable terminology. An UE 115 can also be a cell phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a portable device, a tablet computer, a laptop computer, a cordless phone, a personal device electronic device, a portable device, a personal computer, a local subscriber circuit station (WLL), an Internet of Things (loT) device, an Internet of Everything (loE) device, a machine-type communication device (MTC) , an appliance, a car, among others.
[0087] Base stations 105 can communicate with core network 130 and with each other. For example, base stations 105 can interface with core network 130 through return transport channel links 132 (e.g., SI, etc.). Base stations 105 can communicate with each other via the channel links
Petition 870190100328, of 10/07/2019, p. 50/198
44/113 return transport 134 (for example, X2, etc.), both directly and indirectly (for example, through the core network 130). Base stations 105 can perform radio and programming configurations for communicating with UEs 115, or they can operate under the control of a base station controller (not shown). In some examples, base stations 105 can be macrocells, small cells, access points, or the like. Base stations 105 can also be called evolved NodeBs (eNBs) 105 or next generation NodeBs (gNBs).
[0088] Core network 130 can offer user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing or mobility functions. At least some of the network devices, such as base station 105, may include subcomponents, such as an access network entity or an access node controller (ANC). Each access network entity can communicate with a series of 115 UEs through a series of other access network transmission entities, each of which can be an example of an intelligent radio unit, or a transmission / reception (TRP). In some configurations, various functions of each access network entity or base station 105 can be distributed among several network devices (for example, radio units and access network controllers) or consolidated into a single network device (for example , a base station 105).
[0089] Wireless communication system 100 can operate in an ultra-high frequency (UHF) region
Petition 870190100328, of 10/07/2019, p. 51/198
45/113 using frequency bands from 700 MHz to 2600 MHz (2.6 GHz), although some networks (for example, a wireless local area network (WLAN)) may use frequencies up to 4 GHz. This region also be known as the decimetric band, since the wavelengths vary from approximately one decimeter to one meter in length. UHF waves can propagate mainly through the line of sight, and can be blocked by constructions and environmental barriers. However, the waves can penetrate the walls enough to provide services to UEs 115 located indoors. The transmission of UHF waves is characterized by smaller antennas and shorter range (for example, less than 100 km) compared to transmission using the lower frequencies (and longer waves) of the high frequency or very high frequency (VHF) portion of the spectrum . In some cases, the wireless communications system 100 may also use extremely high frequency (EHF) portions of the spectrum (for example, from 30 GHz to 300 GHz). This region is also known as the millimeter band, since wavelengths vary from approximately one millimeter to one centimeter in length. This way, EHF antennas can be even smaller and have a smaller spacing than UHF antennas. In some cases, this may facilitate the use of antenna arrays within an UE 115 (for example, for directional beam shaping). However, EHF transmissions may be subject to even greater atmospheric attenuation and a shorter range than UHF transmissions.
[0090] Thus, the communications system without
Petition 870190100328, of 10/07/2019, p. 52/198
46/113 wire 100 can support millimeter wave (mmW) communications between UEs 115 and base stations 105. Devices operating in the mmW or EHF bands can have multiple antennas to enable beam forming. That is, a base station 105 can use multiple antennas or antenna arrays to perform beam forming operations for directional communications with a UE 115. Beam forming (which can also be called spatial filtering or directional transmission) is a technique signal processing that can be used on a transmitter (for example, a base station 105) to shape and / or direct a whole antenna beam towards a target receiver (for example, a UE 115). This can be achieved by combining elements in an antenna array in such a way that signals transmitted at certain angles suffer constructive interference, while others suffer destructive interference.
[0091] Wireless multi-input multiple output (MIMO) systems use a transmission scheme between a transmitter (for example, a base station 105) and a receiver (for example, a UE 115), where both the transmitter and the receiver are equipped with multiple antennas. Some parts of the wireless communication system 100 may use beam forming. For example, base station 105 may have an array of antennas with a series of rows and columns of antenna ports that base station 105 can use for beam shaping in its communication with UE 115. Signals can be transmitted multiple times in different directions (for example, each transmission can undergo beam
Petition 870190100328, of 10/07/2019, p. 53/198
Different 47/113). An mmW receiver (for example, a UE 115) can try multiple beams (for example, antenna arrays) while receiving the synchronization signals.
[0092] In some cases, the antennas of a base station 105 or UE 115 may be located within one or more antenna arrays, which can withstand beam shaping or MIMO operation. One or more base station antennas or antenna arrays may be co-located in an antenna array, such as an antenna tower. In some cases, the antennas or antenna arrays associated with a base station 105 may be located in several geographic locations. A base station 105 can use multiple antennas or antenna arrays to perform beam forming operations for directional communications with an UE 115.
[0093] In some cases, the wireless communications system 100 may use both licensed and non-licensed radio spectrum bands. For example, wireless communications system 100 may employ LTE License Assisted Access (LTE-LAA) or Unlicensed LTE (LTE U) radio access technology or NR technology in an unlicensed range, such as 5 GHz frequency range for Industrial, Medical and Scientific (ISM) applications. When operating in the bands of the unlicensed radio frequency spectrum, wireless devices, such as base stations 105 and UEs 115, can employ LBT (lsten-before-talk) procedures to ensure that the channel is cleared before transmitting data . In some cases, operations on unlicensed bands may be based on a
Petition 870190100328, of 10/07/2019, p. 54/198
48/113 CA configuration (carrier aggregation) in conjunction with CCs (component carriers) operating in a licensed range. Operations on the unlicensed spectrum may include downlink transmissions, uplink transmissions, or both. Duplexing in the unlicensed spectrum can be based on frequency division duplexing (FDD), time division duplexing (TD), or a combination of both.
[0094] As discussed above, in some examples, base station 105 can transmit SS blocks that can be used by UEs 115 in system acquisition. SS blocks can include PBCH broadcasts and SS broadcasts, which can be transmitted over different time resources from an SS block. In cases where a base station 105 uses beam conformation, a burst of SS can be scanned by beam by a base station 105 with a periodicity that is configured in an SS burst set configuration. In some cases, PBCH transmissions can be demodulated using SS transmissions, where SS transmissions are used for channel estimation, which can allow an UE to demodulate PBCH transmissions. In some examples, PBCH transmissions may be transmitted using a higher frequency bandwidth than SS transmissions, in which case one or more reference signal transmissions (for example, demodulation reference signal transmissions (DMRS )) on PBCH transmissions can be useful to provide reliable demodulation of PBCH transmissions. In some examples, PBCH transmissions can be demodulated using reference signal transmissions,
Petition 870190100328, of 10/07/2019, p. 55/198
49/113 SS transmissions, or combinations thereof.
[0095] FIG. 2 illustrates an example of a wireless communications system 200 that supports wireless signal reference schemes in accordance with various aspects of the present disclosure. Wireless communication system 200 includes base station 105-a and UE 115-a, which can be examples of aspects of the corresponding devices, as described above with reference to FIG. 1. In the example of FIG. 2, the wireless communications system 200 can operate according to a radio access technology (RAT), such as LTE, 5G or RAT NR, although the techniques described here can be applied to any RAT and systems they can use simultaneously two or more different RATs.
[0096] Base station 105-a can communicate with UE 115-a via a downlink carrier 205 and an uplink carrier 215. In some cases, base station 105-a can allocate resources for SS block transmissions 210, which can be transmitted periodically and can be used by UE 1 15-a to acquire the system. In this example, the SS 210 blocks can include a first SS 210-a block, a second SS 210-b block, and a third SS 210-c block. In some cases, the periodicity of the SS 210 blocks can be configured according to an established standard. In others, the periodicity of the SS 210 blocks can be configured by the base station 105-a and information related to the timing or configuration of the SS 210 blocks can be provided with the SS 210 blocks. In some cases, the base station 105-a can transmit using frequencies of
Petition 870190100328, of 10/07/2019, p. 56/198
50/113 mmW, and SS 210 blocks can be transmitted using beam scanning.
[0097]
Each of the SS 210 blocks in this example can include four symbols. Two of the symbols, namely, the first and third symbols in this example, can include PBCH 225 transmissions. The other two symbols, which are the second and fourth symbols in this example, can include SS transmissions, such as an SSS 230 transmission and a PSS 235 transmission. As noted above, in some examples, PBCH 225 transmissions may have a higher frequency bandwidth than the SSS 230 transmission or the PSS 235 transmission, although the frequency bandwidths can be the same in other examples. In some examples, PBCH 225 transmissions can use 288 frequency tones and occupy four resource blocks (RBs), and each of the SSS 230 transmission and PSS 235 transmission can use 127 tones and occupy two RBs. The frequency of the SSS 230 transmission and the PSS 235 transmission can overlap at least partially with the frequency of PBCH 225 transmissions. Also as discussed above, in some cases, the base station 105-a can use beam scanning to transmit bursts of SS.
[0098]
FIG. 3 illustrates an example of SS 300 burst features that support wireless signal reference schemes in accordance with various aspects of the present disclosure. In some examples, the burst capabilities of SS 300 may implement aspects of the wireless communication systems 100 or 200 of FIGs. 1 or 2. In the example of FIG. 3, a transmission of
Petition 870190100328, of 10/07/2019, p. 57/198
51/113 periodic synchronization 310 can be transmitted by a base station. In this example, a synchronization period of 30 milliseconds X can be configured for a base station, where the synchronization can have a duration of Y milliseconds 315.
[0099] In examples using mmW frequencies, the synchronization transmission 310 may include a burst of SS 320, which may include a series of SS 325 blocks that can be transmitted using different transmission beams in a beam-scan pattern, SS begins with a first block 325 to broadcast in a first direction, and ending with a ^£ Nl SS block 325 b transmitted in a direction N '. Each SS 325-b block can include PBCH transmissions and SS transmissions, as discussed with reference to FIG. 2. As indicated above, a UE receiving PBCH transmission in an SS 425 block can perform channel estimation and demodulation of PBCH transmissions. In some cases, the SSS transmitted within the same SS 425 block as the PBCH transmission, and multiplexed by time division with the PBCH transmission, can be used for channel estimation and demodulation of PBCH transmissions. In such cases, the base station can use transmission parameters, such as antenna ports, which are the same between SS transmission and PBCH transmissions. In addition, PBCH transmissions may include, as indicated above, a dedicated DMRS signal transmitted within the same symbol as the multiplexed PBCH in the frequency domain. Therefore, an UE receiving the transmissions can perform demodulation at least in part based on the SSS signal, in the transmissions
Petition 870190100328, of 10/07/2019, p. 58/198
52/113 of DMRS, or combinations thereof. In some cases, a density of DMRS transmissions can be reduced for parts of PBCH and SS transmissions that use overlapping bandwidth, and an increased density of DMRS transmissions can be used for non-overlapping bandwidths. Additionally, in some cases, an SS transmission can be transmitted from one port (for example, PO antenna port), and the PBCH can be transmitted from two antenna ports, such as one in common with the port SS transmission port and an additional port (for example, PO and Pl antenna ports). In such cases, one or more DMRS tones can be configured on the overlapping bandwidth of PBCH and SS transmissions that can allow channel estimation of the additional antenna port.
[00100] FIG. 4 illustrates an example of SS 400 block features that support wireless signal reference schemes in accordance with various aspects of the present disclosure. In some examples, the SS 400 block features may implement aspects of wireless communication systems 100 and 200. In this example,
the resources in block from SS 400 can include four symbols, two of which is can to be used to stream transmissions in PBCH 405, one can: to be used for transmissions in SS 410, and one can to be used for transmissions in PSS 415. ( Oomo discussed above, at transmissions in PBCH 405 may include transmissions reference signal such as tones or transmissions of DMRS 420. [00101] At the example gives FIG. 4, inside From
Petition 870190100328, of 10/07/2019, p. 59/198
53/113 transmission symbols of PBCH 405, a non-uniform density of DMRS tones can be used. In this example, the portions of the PBCH 405 transmission bandwidth that overlap with the SSS 410 transmission bandwidth may have a reduced density of DMRS 420 tones, and the non-overlapping bandwidths may have an increased density of DMRS 420 tones. As discussed above, a UE may use, in some examples, SSS 410 transmissions for demodulation of PBCH 405 transmissions, and thus the reduced density of DMRS 420 tones in the bandwidth of SSS 410 transmissions. it can also provide sufficient channel estimation for demodulation of PBCH 405 transmissions. In some cases, DMRS 420 tones can be completely omitted from the overlapping bandwidth, and SSS 410 transmissions can be used for demodulation of the PBCH 405 transmission. By providing reduced DMRS 420 tone density, additional PBCH features may be available for broadcast transmissions that can be transmitted on PB5 405 transmissions.
[00102] In other examples, as illustrated in FIG. 5, DMRS tones can be distributed evenly between two PBCH symbols. FIG. 5 illustrates another example of SS 500 block features that support wireless signal reference schemes in accordance with various aspects of the present disclosure. In some examples, the SS 500 block features can implement aspects of the wireless communications system 100. In this example, the SS 500 block features can include four symbols, two of which can be used to transmit PBCH transmissions 505, one can
Petition 870190100328, of 10/07/2019, p. 60/198
54/113 can be used for SS 510 transmissions, and one can be used for PSS 515 transmissions. As discussed above, PBCH 505 transmissions can include reference signal transmissions, such as DMRS 520 transmissions.
[00103] In the example of FIG. 5, DMRS transmissions can be distributed non-uniformly between symbols that contain PBCH 505 transmissions. In this example, the overhead associated with reference signal transmissions can be reduced while still providing enough information to estimate channel and demodulation in an UE. In other cases, a combination of different densities within the symbols of the PBCH 505 transmissions, and between the symbols, can be used. In some cases, the tone indices for DMRS 520 transmissions can be specified for the PBCH 505 transmission symbols. In some examples, a first set of tone indices may be provided for tones that overlap with SSS 510 transmissions. , and a second set of tone indices can be provided for tones that are not overlapping with SSS 510 broadcasts.
[00104] FIG. 6 illustrates another example of SS 600 block features that support wireless signal reference schemes in accordance with various aspects of the present disclosure. In some examples, the SS 600 block features can implement aspects of wireless communication systems 100 and 200. In this example, the SS 600 block features can include four symbols, two of which can be used to transmit PBCH transmissions. 605, one can be used for SS 610 transmissions, and one can be used for
Petition 870190100328, of 10/07/2019, p. 61/198
55/113 PSS 615 transmissions. As discussed above, PBCH 605 transmissions may include reference signal transmissions, such as DMRS 620 transmissions.
[00105] In the example of FIG. 6, DMRS 620 transmissions may be located in DMRS tones alternating between symbols with PBCH transmissions. 605. In some examples, a hop pattern can be applied to the DMRS 620 transmission tones of the first PBCH 605-a transmissions in a first symbol to obtain the tones for DMRS 620 transmissions in a second PB5 605-b transmission in a second symbol. Such alternating tones for DMRS 620 transmissions can provide improved channel estimation and frequency diversity compared to examples using the same set of tones between PBCH 605 transmission symbols. In some cases, none of the 620 transmission tones can overlap between symbols with PBCH 605 transmissions. In other cases, a subset of tones may be common among symbols with PBCH transmissions, as illustrated in FIG. 7.
[00106] FIG. 7 illustrates another example of SS 700 block features that support wireless signal reference schemes in accordance with various aspects of the present disclosure. In some examples, the SS 700 block features can implement aspects of wireless communication systems 100 and 200. In this example, the SS 700 block features can include four symbols, two of which can be used to transmit PBCH transmissions. 705, one can be used for SS 710 transmissions, and one can be used for
Petition 870190100328, of 10/07/2019, p. 62/198
56/113 PSS 715 transmissions. As discussed above, PBCH 705 transmissions may include reference signal transmissions, such as DMRS 720 transmissions.
[00107] In the example of FIG. 7, DMRS 720 transmissions may be located in subsets of tones, in which the tones of a first subset of tones 725-a and a second subset of tones 725-b may be common among the symbols used for PBCH 705 transmissions. DMRS 720 transmissions in tones outside of the 725 tone subsets may use different tones between symbols. By providing common tones between different symbols, it is possible to offer improved estimation of carrier frequency shift. Although the example of FIG. 7 show subsets of tones 725 that are common, other examples (for example, the example in FIG. 4) may determine that the tones in a first PBCH symbol are the same as a set of tones used for DMRS 720 transmissions within a second PBCH symbol.
[00108] The waveform that is used for DMRS transmissions as discussed here can, in some cases, be configured based on one of the PBCH symbols or both PBCH symbols on an SS block. In some cases, the two DMRS signals used in the two PBCH symbols within an SS block can be the same frequency. Such a sequence can be provided, in some examples, when the lengths of the two DMRS sequences (i.e., the number of occupied DMRS tones) are the same.
[00109] In other examples, the DMRS strings for the different PBCH symbols may be partially the same. In such examples, for DMRS transmissions that
Petition 870190100328, of 10/07/2019, p. 63/198
57/113 use the same tones for each symbol, a first DMRS sequence can be used, and a different DMRS sequence can be used for non-common DMRS tones between symbols. For example, a first DMRS sequence '1' can be mapped to a set of S ± tones. Additionally, the set of Si tones can be divided into two subsets Sn and S ± 2, so that the cardinality (Sn) = cardinality (Si ₂ ) · The two DMRS signals transmitted through the Sn and Sn tones can be the same, whereas DMRS signals may be different in the rest of the tones.
[00110] In still other examples, the DMRS sequence for the different PBCH symbols can be completely different. In such cases, the two sequences can be constructed by dividing a long base sequence. For example, the long base sequence can be a Zadoff-Chu sequence, or m sequence, or a cyclic shift therefrom.
[00111] In some examples, DMRS strings, DMRS locations, or combinations thereof, can be used to provide information, such as identification, timing, or configuration information, to a UE. For example, the DMRS sequence (s) for the different PBCH symbols may, separately or together, carry information from any combination of a base station cell ID, timing information, or information about the configuration of synchronization. Timing information may include, for example, SS burst index information within a set of SS bursts, an SS block index within the set of SS bursts, a version indication of
Petition 870190100328, of 10/07/2019, p. 64/198
58/113 redundancy (RV) of the corresponding PBCH (for example, a PBCH can have 4 RVs, carry some level of system timing (for example, 20 msec limits), and the DMRS can include all or part of the RV index which can be used for PBCH decoding), or any combination thereof. The synchronization configuration information can include, for example, information about the SS burst configuration, the SS burst set, the SS periodicity, or any combination thereof. Such information can be provided through any combination of a choice of DMRS sequences (for example, different sequence of bases and the amount of cyclic shifts), or a choice of tone locations allocated to DMRS sequences. In some cases, a mapping that maps different sequences and / or tone locations to different information may be provided.
[00112] FIG. 8 illustrates an example of a process flow 800 that supports wireless signal reference schemes in accordance with various aspects of the present disclosure. In some examples, process flow 800 can implement aspects of wireless communications system 100. Process flow 800 includes UE 115-b and base station 105-b, each of which can be an example of the corresponding device described with reference to FIGs. 1 and 2.
[00113] In 805, the base station 105-b can configure the SS and broadcast channel resources. As discussed above, in some cases, base station 105-b can configure an SS block that includes symbols for
Petition 870190100328, of 10/07/2019, p. 65/198
59/113 PBCH transmissions and symbols for SS transmissions. The burst transmission of SS 810 can be transmitted by the base station 105-b according to the configured resources.
[00114] The UE 115-b, at 815, can identify the SS and broadcast channel transmissions. In some cases, the UE 115-b can monitor synchronization transmissions according to a specified synchronization delay. In cases using mmW frequencies, the SS 810 burst transmission can be transmitted as part of a beam scan procedure, and the UE 115-b can receive the SS 810 burst transmission using one or more of the transmission beams from the beam scanning procedure.
[00115] At 820, UE 115-b can identify reference signal resources in the broadcast channel. In some cases, the reference signal resources may be frequency tones that are configured for DMRS transmissions. In some cases, the broadcast channel transmission may be a PBCH transmission that may include two PBCH symbols in the broadcast channel time resources.
[00116] In option block 825, UE 115-b can determine one or more of a cell ID, timing information, or configuration information based on the received reference signal transmission. In some cases, the reference signal sequence or waveform can be used to determine such information. In other cases, a location of the reference signal resources, such as the tones used for DMRS transmissions, can be used to determine such information. In other cases, a combination of a reference signal sequence and
Petition 870190100328, of 10/07/2019, p. 66/198
60/113 location of the reference signal resources can be used to determine such information.
[00117] In block 830, the UE 115-b can decode the broadcast channel based on the reference signal resources and SS transmissions. In some cases, UE 115-b may decode PBCH transmissions based on DMRS transmissions in DMRS resources, as discussed above. UE 115-b and base station 105-b can then perform an 835 connection establishment. For example, UE 115-b can transmit a random access request, which can initiate a random access procedure to establish a connection between the station base 105-beo EU 115-b.

106/113 (HRPD), etc. UTRA includes broadband CDMA (WCDMA) and other variants of CDMA. A TDMA system can implement radio technology, such as the Global System for Mobile Communications (GSM).
[00212] An OFDMA system can implement radio technology, such as Ultra-Mobile Broadband (UMB), Evolved UTRA (E-UTRA), Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDMA, etc. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). LTE and LTE-A are versions of UMTS that use EUTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, R and GSM are described in the documents of the organization called 3GPP (3rd Generation Partnership Project). CDMA2000 and UMB are described in the documents of an organization called 3rd Generation Partnership Project 2 (3GPP2 - 3rd Generation Partnership Project 2). The techniques described here can be used for the radio systems and technologies mentioned above, as well as other radio systems and technologies. Although aspects of an LTE or NR system can be described for example, and LTE or NR terminology can be used in much of the description, the techniques described here are applicable in addition to LTE or NR applications.
[00213] In LTE / LTE-A networks, including such networks described here, the term evolved node B (eNB) can generally be used to describe base stations. The wireless communications system or systems described here may include a heterogeneous LTE / LTE-A or NR network in which different types of eNBs provide coverage for various
Petition 870190100328, of 10/07/2019, p. 113/198
107/113 geographic regions. For example, each eNB, next generation NodeB (gNB) or base station can provide communication coverage for a macrocell, a small cell or other types of cell. The term cell can be used to describe a base station, a carrier or component carrier associated with a base station, or a coverage area (eg, sector, etc.) of a carrier or base station, depending on the context.
[00214] Base stations may include or be called, by those skilled in the art, a base transceiver station, base station, access point, radio transmitter, NodeB, eNodeB (eNB), gNB, NodeB Residencial, eNodeB Residencial, or some other proper terminology. The geographic coverage area for a base station can be divided into sectors that make up only part of the coverage area.

108/113 relatively large (for example, radius of several kilometers) and can allow unrestricted access by UEs with service subscriptions with the network provider. Small cells can include picocells, femtocells, and microcells according to several examples. A picocell, for example, can cover a small geographical area and can allow unrestricted access by UEs with service subscriptions with the network provider. A femtocell can also cover a small geographical area (for example, a residence) and can provide access restricted by UEs having an association with the femtocell (for example, UEs in a closed subscriber group (CSG), UEs for users in the residence, among others). An eNB for a macrocell can be called an eNB macro. A small cell eNB can be called a small cell eNB, pico-eNB, femto-eNB or residential eNB. An eNB can support one or multiple (for example, two, three, four, and so on) cells (for example, component carriers).
[00216] The wireless communication system or systems described here may support synchronous or asynchronous operation. For synchronous operation, the base stations can have a similar frame timing, and the transmissions from different base stations can be approximately aligned in time. For asynchronous operation, base stations may have a different frame timing, and transmissions from different base stations may not be time aligned. The techniques described here can be used for both synchronous and asynchronous operations.
