TECHNIQUES FOR DOUBLE MODE OPERATIONS IN NEW RADIO CROSS REFERENCE TO RELATED APPLICATIONS [0001] This Patent Application claims priority to US Non-Provisional Application No. 15 / 920,043, entitled TECHNIQUES FOR DUAL-MODE OPERATIONS IN NEW RADIO presented on March 13 2018 and US Provisional Order Serial No. 62 / 476,472, entitled DUALMODE OPERATION IN A WIDEBAND CO IN NR and filed on March 24, 2017, which are expressly incorporated by reference here in their entirety.
BACKGROUND [0002] Aspects of the present disclosure generally refer to wireless communications, and more particularly, to techniques and schemes for dual-mode operations on a wireless communication network (for example, on a broadband component carrier ( CC)) in new radio (NR) from 5 ^to Generation (5G)).
[0003] Wireless communication networks are widely implemented to provide various types of communication content, such as voice, video, data packets, messages, transmission and so on. These systems can be multiple access systems capable of supporting communication with multiple users, sharing the available resources of the system (for example, time, frequency and power). Examples of such multiple access systems include multiple access systems include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access systems (FDMA), systems multiple access by
Petition 870190093060, of 9/17/2019, p. 6/86
2/59 orthogonal frequency division (OFDMA), single carrier frequency multiple access systems by division (SC-FDMA) and multiple access systems by synchronous code division by time division (TD-SCDMA).
[0004] These multiple access technologies have been adopted in several telecommunications 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 Long Term Evolution (LTE) or Advanced LTE (LTE-A). Although the newer multiple access systems, such as an LTE or LTE-A system, offer faster data transfer rates than older technologies, such increased downlink rates have caused a greater demand for higher bandwidth content, such as high resolution graphics and videos, for use on or with mobile devices. In response, a fifth generation (5G) wireless communication technology (which may be called a new radio (NR)) is expected to expand and support various usage scenarios and applications in relation to current generations of mobile networks. In one respect, 5G communication technology may include: enhanced mobile broadband (eMBB), addressing human-centered use cases for accessing multimedia content, services and data; ultra-reliable low-latency communications (URLLC) with strict requirements, especially in terms of latency and reliability; and massive machine-type communications (mMTC) to a very large number of connected devices and typically transmitting a relatively low volume of information

3/59 sensitive to no delay. As the demand for mobile broadband access continues to increase, there is a need for further improvements in NR communications technology and beyond. Preferably, these improvements should apply to other multiple access technologies and to the telecommunications standards that employ those technologies.
[0005] Consequently, due to the requirements for increased data rates, higher capacity and lower latency, new approaches may be desirable to improve the reliability and efficiency of the system. For example, for NR communications technology and beyond, there may be difficulties in supporting different user equipment (UEs) with different UE resources. For example, since the system bandwidth in NR can be up to 1 GHz, there can be challenges in supporting UEs with different bandwidth resources. Thus, improvements in wireless communications operations may be desired to satisfy consumer demand and improve the user experience in wireless communications, for example, NR communications.

DETAILED DESCRIPTION [0027] Several aspects are now described with reference to the drawings. In the following description, for the sake of explanation, several specific details are set out in order to provide a complete understanding of one or more aspects. It may be evident, however, that such aspects can be practiced without these specific details. In addition, the term component, as used here, can be one of the parts that make up a system, can be hardware, firmware and / or software stored in a computer-readable medium and can be divided among other components.
[0028] The present disclosure generally refers to a wireless communication network, such as an NR technology network having a broadband component (CC) carrier, and components on a UE and base station that configure and manage different types of UEs having different bandwidth resources to enable broadband CC operations. For example, the bandwidth feature may include, but is not limited to, radio frequency (RF) bandwidth feature. That is, this disclosure describes how the broadband CC, for example, the system bandwidth, can be configured to exchange signaling between the UE and the base station when some UEs may have broadband resources while other UEs may have narrowband resources.
Petition 870190093060, of 9/17/2019, p. 14/86
10/59
In some examples, the system bandwidth of a CC (for example, the broadband DC) on an NR technology network (for example, up to 1 GHz) may be greater than the bandwidth of the CC system. a DC on an LTE network (for example, up to 20 MHz).
[0029] For example, in an implementation, the UE and base station are configured to take into account a value (for example, a frequency range, such as 100 MHz) of the system bandwidth, a bandwidth resource minimum UE (or reference capacity) that is supported by the base station (for example, a channel bandwidth of 20 MHz), and a UE bandwidth resource (for example, a maximum channel bandwidth that UE can support), and thereby determine a specific UE set of parts of the bandwidth (for example, one or more portions of the system bandwidth) that can be used as channels or CCs to exchange communications. As such, the broadband CC can be configured for dual mode operations to support both the UEs having broadband resources and the UEs having narrow band resources by differently configuring specific UE sets configured for parts of the bandwidth.
[0030] In other alternatives, this disclosure describes yet another apparatus and methods in the UE and base station to manage or control other signaling or configurations based on one or more specific UE sets of parts of the bandwidth. Examples of such other apparatus and methods may include managing one or more of synchronization and signaling channels,
Petition 870190093060, of 9/17/2019, p. 15/86
11/59 rate, aggregation of part of the bandwidth, generation and use of random sequence, and configuration and interoperability of one or more specific UE sets of parts of the bandwidth with channels and channel quality signaling.
[0031] Thus, the apparatus and methods of this disclosure may allow different configurations for UEs having different bandwidth resources to exchange signaling with the base station, thereby allowing dual mode use of broadband DC (for example, system bandwidth) on a wireless communication network based on NR technology.
[0032] Additional features of the present aspects are described in more detail below in relation to Figures 1-13.
[0033] It should be noted that the techniques described here can be used for various wireless communication networks such as CDMA, TDMA, FDMA, OFDMA, SCFDMA, and other systems. The terms system and network are often used interchangeably. A CDMA system can implement radio technology such as CDMA2000, Universal Access by Terrestrial Radio (UTRA), etc. CDMA2000 covers the IS-2000, IS-95 and IS-856 standards. IS-2000 versions 0 and A are commonly known as CDMA2000 IX, IX, etc. IS-856 (TIA-856) is commonly referred to as CDMA2000 IxEV-DO, high rate packet data (HRPD), etc. UTRA includes CDMA broadband (WCDMA) and other variants of CDMA. A TDMA system can implement radio technology such as the Global System for Mobile Communications (GSM). An OFDMA system
Petition 870190093060, of 9/17/2019, p. 16/86
12/59 can implement radio technology such as Ultra Mobile Broadband (UMB), Evolved UTRA (E-UTRA), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, FlashOFDMTM, etc. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). Long-term evolution of 3GPP (LTE) and LTE-Advanced (LTE-A) are new releases of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A and GSM are described in documents from a named Partnership Project organization 3 Generation (3GPP). CDMA2000 and UMB are described in documents from an organization named Partnership Project 3 Generation 2 (3GPP2). The techniques described here can be used for the radio systems and technologies mentioned above as well as other radio systems and technologies, including cellular communications (for example, LTE) over a shared radio frequency band. The description below, however, describes an LTE / LTE-A system for example purposes, and LTE terminology is used in much of the description below, although the techniques are applicable in addition to LTE / LTE-A applications (for example , for NR networks or other next generation communication systems).
[0034] The following description provides examples, and is not limiting the scope, applicability, or examples presented in the claims. Changes can be made to the function and arrangement of elements discussed without departing from the scope of the disclosure. Various examples may omit, replace, or add various procedures or components, as appropriate. For example, the methods described can be performed in a different order than the
Petition 870190093060, of 9/17/2019, p. 17/86
13/59 described and several steps can be added, omitted or combined. In addition, the features described in relation to some examples can be combined into other examples.
[0035] With reference to Figure 1, according to various aspects of the present disclosure, an example of a wireless communication network 100, such as an NR technology network having a broadband component (CC) carrier, includes at least one UE 110 with a modem 140 having a communication component 150 that allows the UE 110 to exchange signaling with a modem 170 and a communication component 180 of at least one base station 105 (e.g., a gNB). The communication component 150 of UE 110 and the communication component 180 of base station 105 can respectively include a portion of the bandwidth 152, 182 which allows the UE 110 and base station 105 to determine how the broadband DC , for example, system bandwidth, can be configured to change signaling.
[0036] For example, in an implementation, each part of the bandwidth determiner 152, 182 is configured to take into account a value (for example, frequency range, such as 100 MHz) of the system bandwidth, a minimum UE bandwidth resource (or reference capacity) that is supported by base station 105 (for example, a 20 MHz channel bandwidth), and an EU 110 bandwidth resource (for example, a maximum channel bandwidth that the UE 110 can support), and thereby determine a specific UE set of parts of the 302 bandwidth (for example, one or more portions of the bandwidth of the
Petition 870190093060, of 9/17/2019, p. 18/86
14/59 system, 302-a, 302-b, 302-c, and / or 302-d) that will be used as channels or component carriers to exchange communications. Different UEs 110 with different bandwidth resources can thus have specific set of UE differently configured from parts of bandwidth 302.
[0037] In addition, each controller of part of the bandwidth 154, 184 is configured to work with respective modem 140, 170 and / or other components of UE 110 or base station 105 to ensure that signaling is based on a specific set of UE of parts of the bandwidth 302 determined for each UE 110.
[0038] In additional alternatives, the communication component 150 of UE 110 and the communication component 180 of base station 105 may include one or more additional components to manage or control another signaling or configuration based on specific UE set of parts of the bandwidth 302. Examples of such other components may include components that manage one or more of synchronization and signaling channels, rate matching, aggregation of part of the bandwidth, generation and use of random string, and set configuration and interoperability UE-specific parts of bandwidth 302 with channels and channel quality signaling.
[0039] Thus, the apparatus and methods of this disclosure allows different configurations for UEs 110 having different bandwidth resources, thereby allowing the use of dual mode of broadband DC (for example, system bandwidth) in a network of
Petition 870190093060, of 9/17/2019, p. 19/86
15/59
wireless based communication in technology from NR 1 00.[0040] The network of Communication wireless 100 can include one or more stations base 105, one or more UEs 110, and a main network 115. The main network 115 can
provide user authentication, access authorization, tracking, Internet protocol (IP) connectivity and other access, routing or mobility functions. Base stations 105 can interface with main network 115 via backhaul links 120 (e.g., Sl, etc.). Base stations 105 can perform radio configuration and programming for communication with UEs 110, or they can operate under the control of a base station controller (not shown). In several examples, base stations 105 can communicate, directly or indirectly (for example, through main network 115), with each other through backhaul links 125 (for example, XI, etc.), which can be wired and wireless communication.
[0041] Base stations 105 can communicate wirelessly with UEs 110 through one or more base station antennas. Each base station 105 can provide communication coverage for a respective geographic coverage area 130. In some examples, base stations 105 can be referred to as a base transceiver station, a radio base station, an access point, a node access, a radio transceiver, a NodeB, eNodeB (eNB), gNB, Home NodeB, a Home eNodeB, a relay, or some other suitable terminology. Geographic coverage area 130 for a base station 105 can be divided into sectors or cells make up only a portion of the coverage area (not
Petition 870190093060, of 9/17/2019, p. 20/86
16/59 shown). Wireless communication network 100 can include base stations 105 of different types (for example, macro base stations or small cell base stations, described below). In addition, the plurality of base stations 105 can operate according to different communication technologies (for example, 5G (New radio or NR), fourth generation (4G) / LTE, 3G, Wi-Fi, Bluetooth, etc. .), and thus can be overlapping geographical coverage areas 130 for different communication technologies.
[0042] In some examples, the wireless communication network 100 may be or include any or any combination of communication technologies, including an NR or 5G technology, a Long Term Evolution (LTE) or LTE-Advanced (LTE-A ) or MuLTEfire technology, Wi-Fi technology, Bluetooth technology, or any other long- or short-range wireless communication technology. In LTE / LTE-A / MuLTEfire networks, the term evolved B node (eNB) can generally be used to describe base stations 105, while the term UE can generally be used to describe UEs 110. The wireless communication network 100 can be a heterogeneous technology network in which different types of eNBs provide coverage for various geographic regions. For example, each eNB or base station 105 can provide communication coverage for a macro cell, a small cell, or other types of cell. The term cell is a 3GPP term that can be used to describe a base station, a carrier or component carrier associated with a base station, or a coverage area (e.g., sector,
Petition 870190093060, of 9/17/2019, p. 21/86
17/59, etc.) from a carrier or base station, depending on the context.
[0043]
A macro cell can generally cover a relatively large geographical area (for example, several kilometers in radius) and can allow unrestricted access by UEs 110 with service signatures with the network provider.
[0044]
A small cell can include a base station of lower relative transmit power, compared to a macro cell, which can operate in the same or different frequency bands (for example, licensed, unlicensed, etc.) as macro cells. Small cells can include pico cells, femto cells, and micro cells according to several examples. A peak cell, for example, can cover a small geographic area and can allow unrestricted access by UEs 110 with service signatures with the network provider. A femto cell can also cover a small geographical area (eg a household) and can provide restricted access and / or unrestricted access by UEs 110 having an association with the femto cell (eg, in the case of restricted access, UEs 110 in a closed subscriber group (CSG) of base station 105, which may include UEs 110 for home users, and the like). An eNB for a macro cell can be called an eNB macro. A small cell eNB can be referred to as a small cell eNB, a peak eNB, a femto eNB, or a household eNB. An eNB can support one or multiple cells (for example, two, three, four, and the like) (for example, component carriers).
Petition 870190093060, of 9/17/2019, p. 22/86
18/59 [0045] The communication networks that can accommodate some of the various examples published may be packet-based networks that operate according to a layered protocol stack and data on the user plane may be based on an internet protocol (IP). A user plan protocol stack (for example, packet data convergence protocol (PDCP), radio link control (RLC), media access control (MAC), etc.), can perform segmentation and reassembly of packets to communicate through logical channels. For example, a MAC layer can perform priority manipulation and multiplexing of logical channels to transport channels. The MAC layer can also use hybrid auto-repeat / solidification (HARQ) to provide relay at the MAC layer to improve link efficiency. In the control plane, the radio resource control protocol (RRC) layer can provide for establishing, configuring and maintaining an RRC connection between an UE 110 and 105 base stations. The RRC protocol layer also can be used for the radio support of the main network 115 of users of the user plan data. In the physical layer (PHY), transport channels can be mapped to physical channels.
[0046] UEs 110 can be dispersed throughout the wireless communication network 100, and each UE 110 can be stationary or mobile. A UE 110 may also include or be called by the person skilled in the art as a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a
Petition 870190093060, of 9/17/2019, p. 23/86
19/59 remote unit, a mobile device, a wireless device, a wireless communication device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a phone, a user agent, a mobile client, a client or some other suitable terminology. An UE 110 can be a cell phone, a smart phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a portable device, a tablet, a laptop, a cordless phone, a watch wireless local loop station (WLL), an entertainment device, a vehicle component, customer facilities equipment (CPE) or any device capable of communicating on the 100 wireless communication network. UE 110 can be the Internet of Things (IoT) and / or machine to machine device (M2M), for example, low power device and low data rate (in relation to a cordless phone, for example), which can, in some ways, communicating infrequently with the wireless communication network 100 or other UEs. An UE 110 may be able to communicate with various types of base stations 105 and network equipment, including macro eNBs, small cell eNBs, macro gNBs, small cell gNBs, relay base stations, and the like.
[0047] UE 110 can be configured to establish one or more wireless communication links 135 with one or more base stations 105. Wireless communication links 135 shown in wireless communication network 100 can carry uplink (UL) transmissions from an UE
Petition 870190093060, of 9/17/2019, p. 24/86
20/59
110 for a base station 105, or downlink transmissions (DL), from a base station 105 to a UE 110. Downlink transmissions can also be called direct link transmissions, while uplink transmissions can also be called reverse link transmissions. Each wireless communication link 135 can include one or more carriers, where each carrier can be a signal made up of multiple subcarriers (for example, waveform signals of different frequencies) modulated according to the various radio technologies described above . Each modulated signal can be sent on a different subcarrier and can carry control information (for example, reference signals, control channels, etc.), general information, user data, etc. In one aspect, wireless communication links 135 can transmit bidirectional communications using frequency division duplex (FDD) operation (for example, using paired spectrum resources) or time division duplex (TDD) operation (for example, using unpaired spectrum resources). Frame structures can be defined for FDD (for example, frame type 1) and TDD (for example, frame structure type 2). In addition, in some respects, wireless communication links 135 may represent one or more broadcast channels.
[0048] In some aspects of the wireless communication network 100, base stations 105 or UEs 110 may include multiple antennas to employ antenna diversity schemes to improve communication quality and reliability between base stations 105 and UEs 110. Additionally or in a way alternative, the seasons
Petition 870190093060, of 9/17/2019, p. 25/86
21/59 base 105 or UEs 110 can use multiple input multiple input (MIMO) techniques that can take advantage of multipath environments to transmit multiple spatial layers that carry the same or different encoded data.
[0049] The wireless communication network 100 can support operations in multiple cells or carriers, a feature that can be termed as carrier aggregation (CA) or multi-carrier operation. A carrier can also be referred to as a component carrier (CC), a layer, a channel, etc. The terms carrier, component carrier, cell, and channel can be used interchangeably here. A UE 110 can be configured with multiple downlink CCs and one or more uplink CCs for carrier aggregation. Carrier aggregation can be used with both FDD and TDD component carriers. Base stations 105 and UEs 110 can use spectrum up to Y MHz (for example, Y = 5, 10, 15 or 20 MHz) of bandwidth per carrier allocated in a carrier aggregation of up to a total of Yx MHz (x = number of 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 in relation to DL and UL (for example, more or less carriers can be allocated to DL than to UL). Component carriers may 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 cell
Petition 870190093060, of 9/17/2019, p. 26/86
22/59 secondary (SCell)).
[0050] The wireless communication network 100 may also include base stations 105 operating in accordance with Wi-Fi technology, for example, Wi-Fi access points, in communication with UEs 110 operating in accordance with Wi-Fi technology, for example, Wi-Fi stations (STAs) through communication links on an unlicensed frequency spectrum (for example, 5 GHz). When communicating over an unlicensed frequency spectrum, STAs and APs can perform a clear channel assessment (CCA) or listen before the conversation procedure (LBT) before communication to determine if the channel is available.
[0051] Additionally, one or more of base stations 105 and / or UEs 110 can operate according to an NR or 5G technology called millimeter wave technology (mmW or mm wave). For example, mmW technology includes transmissions at frequencies of mmW and / or frequencies close to mmW. The extremely high frequency (EHF) is part of the radio frequency (RF) in the electromagnetic spectrum. The EHF has a range of 30 GHz to 300 GHz and a wavelength between 1 millimeter and 10 millimeters. The radio waves in this band can be termed as a millimeter wave. The nearby mmW can extend up to a frequency of 3 GHz with a wavelength of 100 mm. For example, the super high frequency band (SHF) extends between 3 GHz and 30 GHz, and can also be called a centimeter wave. Communications using the mmW radio frequency band and / or the nearby mmW have extremely high loss of travel and a short range.

23/59
As such, base stations 105 and / or UEs 110 operating in accordance with mmW technology can use beam conformation in their transmissions to compensate for extremely high loss of travel and short range.
[0052] With reference to Figure 2, a channel 200 in an NR 100 wireless communication system (Figure 1) can be considered to be a broadband channel having a maximum or substantially greater channel bandwidth 202 than a maximum channel bandwidth in an LTE wireless communication system. For example, in LTE, each channel (also called a component carrier (CC)), can be up to 20 MHz, while in NR, each CC can have a much larger bandwidth, for example, up to 1 GHz.
[0053] In an aspect of NR, it is expected that at least some UEs 110 may not be able to support the maximum channel bandwidth that base station 105 can support. For example, different types of UEs 110 can support different maximum channel bandwidths, such as but not limited to a maximum channel bandwidth of 20 MHz, or 40 MHz, or 80 MHz, etc., while the base station 105 can support a maximum channel bandwidth of 200 MHz. Furthermore, in another aspect, even though the UE 110 is capable of supporting a large bandwidth, the UE 110 or the base station 105 can implement broadband using multiple radio frequency (RF) chains and multiple Fast Fourier Transform (EFT) components. In some implementations, base station 105 can support a broadband channel in a similar manner.
Petition 870190093060, of 9/17/2019, p. 28/86
Thus, due to the different types of UEs 110 and / or different types of base stations 105 having different bandwidth resources 204, 206 (for example, RE bandwidth resources), respectively, it is It is possible that the UE 110 and the base station 105 may or may not support the same maximum channel bandwidth. For example, the different use cases 208, 210, 212, 214 (respectively corresponding to Case 1, Case 2, Case 3, and Case 4) illustrate potential bandwidth capabilities of channel 204, 206 of base station 105 and EU 110, respectively. In case of use 208 (Case 1), UE 110 and base station 105 can have respective bandwidth resources of channel 204, 206 for both to support a single, broadband channel 200. In case of use 210 (Case 2), UE 110 may have channel 206 bandwidth resources to support a single, broadband channel 200, while base station 105 may have channel 204 bandwidth resources to support a plurality (e.g. two in this example) smaller channels (which can be termed narrowband channels) that span broadband channel 200. In use case 212 (Case 3), base station 105 can have channel 204 bandwidth capabilities to support a single, broadband channel 200, while UE 110 may have bandwidth capabilities of channel 206 to support a plurality (for example, two in this example) of smaller channels (for example, narrowband channels) that include broadband channel 200. In case of use 214 (Case 4), the base station 105 and UE 110 can have respective channel bandwidth resources 204, 206 for each to support a plurality (e.g.
Petition 870190093060, of 9/17/2019, p. 29/86
25/59 example, two in this example) of smaller channels (for example, narrowband channels) covering broadband channel 200.
[0055] In some instances, the UE 110 and base station 105 can support operations of about a contiguous 1 GHz spectrum, including a maximum single carrier bandwidth of at least 80 MHz. In addition, the UE 110 and base station 105 can support one or more multi-carrier approaches, for example, carrier aggregation (CA) or dual connectivity (DC), and / or operations on a non-contiguous spectrum. In some cases, UE 110 and base station 105 can support single carrier operations, where the maximum bandwidth supported by some UE resources (or categories) may be less than the bandwidth of the single carrier serving channel. . In some respects, some UE resources (or categories) may or may not support the bandwidth of the single carrier channel it serves.
[0056] In some examples, for each NR carrier (for example, an NR CG), the UE 110 and base station 105 can support operations using a maximum channel bandwidth of 400 MHz, 800 MHz, or 1000 MHz (1 GHz). In other words, the UE 110 and the base station 105 can support operations using a maximum channel bandwidth per NR carrier of [400, 800, 1000] MHz. In one aspect, the UE 110 and the base station 105 can support operations using a maximum channel bandwidth up to 100 MHz per NR carrier. In another aspect, operations using a maximum channel bandwidth of at least 100 MHz per NR carrier can be
Petition 870190093060, of 9/17/2019, p. 30/86
26/59 supported by the UE 110 and the base station 105. Furthermore, the UE 110 and the base station 105 can support operation differently in different frequency bands. For example, for operations below 6 GHz, 100 MHz can be used for the maximum channel bandwidth, while the maximum channel bandwidth wider than 100 MHz can be used for operations above 6 GHz. noted that UE 110 and base station 105 can support operations using a maximum channel bandwidth, for example, 40 MHz or 200 MHz, or using scalable design (s) for up to a maximum channel bandwidth by NR carrier.
[0057] Additionally, the UE 110 and the base station 105 can support operations using a maximum number of NRs carriers for CA and / or DC. For example, although not limited here, such a maximum number of NRs carriers can be selected from the set [8, 16, 32]. Also, in some cases, but not limited here, the maximum FFT size is not greater than one in the set of [8192, 4096, 2048] for the operations discussed here. In addition, in another case, if the maximum channel bandwidth is greater than or equal to 400 MHz and less than or equal to 1000 MHz (1 GHz), then the maximum number of channels (for example, number maximum carrier of NRs or CCs) in any aggregation can be 8 or 16 (but is not limited to that). In another case, if the maximum channel bandwidth is greater than or equal to 100 MHz, then the maximum number of CCs in any given aggregation can be 16 or 32 (but is not limited to that). In yet another case, if the maximum channel bandwidth is greater than 100 MHz
Petition 870190093060, of 9/17/2019, p. 31/86
27/59 and less than 400 MHz, then the maximum number of CCs can be determined to be one of the values noted above or a new value set by the system operators.
[0058] With reference to Figure 3, a base station 105 (for example, or a base station cell 105) can serve one or more UEs 110 capable of supporting broadband signals, while also serving one or more other UEs 110 that are not able to support broadband signals. In some instances, for dual mode operation, broadband channel 200 can be organized or configured into a set of one or more parts of the bandwidth (BPs) 302 (for example, 302-a, 302-b, 302c , and / or 302-d), based on channel 206 bandwidth resource of a respective UE 110. For example, each part of bandwidth 302 can be a separate channel or carrier. As such, for an EU with a bandwidth capacity of 304 and two UEs with a capacity of narrow band 306, 308 (for example, UEs 306, 308 may be different, and may not be able to support broadband signals), broadband 200 can be configured in respective specific sets of the UE of parts of the bandwidth: set 310, set 312, and set 314. In one aspect, each specific set of the UE of parts of the bandwidth of sets 310, 312, and 314 can have one or more BPs 302. In addition, different parts of the bandwidth 302 of a respective UE-specific set of parts of the bandwidth (e.g., set 310, set 312, or set 314) can have a same size (or bandwidth range) as BP 316 size for narrowband EU 306 and / or can be different sizes, or
Petition 870190093060, of 9/17/2019, p. 32/86
28/59 some combination of the same and different sizes (for example, size of BP 318 and size of BP 320 for narrowband EU 308).
[0059] As an example, base station 105 (for example, or a cell of base station 105) can have a system bandwidth of 100 MHz (for example, channel 200 bandwidth) that can be arranged to have a portion of the 302-a bandwidth, or five (5) BPs (for example, five BPs 302-b, or two BPs 302-c plus three BPs 302-d). Assuming that two (2) guard bands (GBs) 301 are 10% (10%) of the 100 MHz system bandwidth (totaling 10 MHz for two GBs, each GB 301 has a bandwidth 330 that is equal to 5 MHz), there is 90 MHz in the cell that can be used for traffic. In one aspect, the UE 304 broadband may be able to support the entire bandwidth of the system and therefore can operate using a single carrier (for example, a single BP 302-a with a size of 90 MHz). Although in one example the UE 304 broadband can be described as using BP 302-a, it should be understood that in some implementations that use essentially the entire bandwidth of the system it cannot be considered using BP 302a. In some respects, the use of BPs 302 can be considered associated with narrowband UEs, such as narrowband UE 306 and / or narrowband UE 308. In a first example, like the narrowband UE 306, each part of the 302-b bandwidth is 18 MHz (indicated by 316). In a second example, as for the narrowband EU 308, each of the three (3) middle parts of the 302-d bandwidth has a large size (for example, 19.8
Petition 870190093060, of 9/17/2019, p. 33/86
29/59
MHz; indicated by 318), while each of the two (2) edge bandwidth pieces 302-c are smaller in size (for example, (90-19.8x3) / 2 = 15.3 MHz; indicated by 320) .
[0060] In some respects, the set of BPs 302 for a cell can be derived based on the system bandwidth and a sustained minimum UE bandwidth resource or a reference capacity (for example, 20 MHz). Based on the reference set of BPs and a respective 206 bandwidth resource, UE 110 can derive its own set of BPs, referred to as a specific set of UEs of BPs (for example, one or more sets of 310, 312, 314). For example, if the UE 110 is capable of 40 MHz in a 100 MHz system bandwidth cell, the UE 110 can determine or be configured to have BP1 plus BP2 (BP1 + BP2) as a first BP, BP3 plus BP4 (BP3 + BP4) as a second BP, and BP5 as a third or the last BP in the UE's specific set of BPs. In this example, each BP of BP1, BP2, BP3, BP4, and BP5 (or BPs 302-b, 302-c, and 302-d) is no more than 20 MHz. As such, the UE 110 can use the smallest BP size, for example, a size equal to or less than the reference resource and creating a new set of BPs using that smaller size in combination with the UE bandwidth resource.
[0061] According to some implementations, in a dual mode operation on a broadband system bandwidth using the set of UE specific BPs, the UE 110 and the base station 105 may also be responsible for other signaling. In some instances, the
Petition 870190093060, of 9/17/2019, p. 34/86
30/59 presence of channels or sync signals in one or more parts of the bandwidth can be determined by UE 110. For example, channels or sync signals may include a physical transmission channel (PBCH), primary sync signal (PSS) or Secondary sync signal (SSS). In an implementation, for example, the presence of channels or synchronization signals can be indicated by base station 105 (for example, a gNB). For example, base station 105 may transmit or transmit a synchronization presence indicator. In some cases, the synchronization presence indicator may be a semi-static indication included in a transmission signal or it may be a dynamic indication. In one aspect, based on the indicated presence, the UE 110 can perform rate matching for one or more other channels (for example, a Physical Downlink Shared Channel (PDSCH)).
[0062] According to some implementations, in a dual mode operation on a bandwidth of the broadband system using the specific set of BPs UE, UE 110 which is a narrowband UE (for example, with features of narrow bandwidth) can perform BP aggregation (for example, two or more PBs). In some instances, BP aggregation can be performed in the same or similar way compared to CA in an LTE network. In some respects, between one or more BPs 302 that a narrowband UE 110 is being served, at least one BP 302 can carry synchronization (e.g., PSS, SSS) information or PBCH, etc. In an LTE network, each CC can have a respective
Petition 870190093060, of 9/17/2019, p. 35/86
31/59 synchronization signal or PBCH. In contrast, in an NR network (for example, the wireless communication network based on NR 100 technology), not every CC has a respective synchronization signal or PBCH, and UE 110 can use the synchronization information or PBCH in a first BP to a second PE. In one example, the second BP may have no synchronization or PBCH information.
[0063] According to some implementations, in a dual-mode operation in bandwidth of the broadband system using the UE's specific set of BPs, the UE 110 and the base station 105 may be responsible for generating the sequence. For example, random sequences can be used for shuffling, modulation of the demodulation reference signal (DM-RS) (for example, used as DM-RS sequence (s)), channel interleaving, etc. In some instances, sequence generation may be applicable to DL and / or UL channels or signals. In one example, UE 110 and base station 105 can use a sequence generation scheme for all channels or NR signals. In another example, UE 110 and base station 105 may use different sequence generation schemes for different channels or NR signals.
[0064] In some respects, the UE 110 and the base station 105 can implement one of at least two sequence generation schemes. In a first scheme, the sequence generation is based on broadband operations (for example, a dual mode operation on the broadband system's bandwidth). In other words, for example, both broadband and narrowband UEs can have the same sequence generation, making the
Petition 870190093060, of 9/17/2019, p. 36/86
32/59 easier system to have orthogonal multiplexing between that broadband and narrowband UEs. In one aspect, narrowband UEs can assume the corresponding portion of the sequence for a respective BP 302. In another aspect, narrowband UEs can be indicated (for example, by base station 105) a resource block index physical (PRB) and / or a BP index to determine the corresponding sequence and / or the corresponding portion of the sequence. For example, but not limited to, the PRB index or BP index indication can be included in a system information block (SIB), and can be received from base station 105 (for example, via a broadcast signal).
[0065] In a second scheme, the sequence generation is performed or performed by PE respectively. For example, UE 110 or base station 105 can determine a respective BP 302, and perform sequence generation for the respective BP 302. In some implementations, the second scheme may be applicable for narrowband UEs only. In other implementations, the second scheme can also be used for broadband UEs. For example, broadband UE 304 can sew together the strings for each BP 302 to form a sequence for the higher band amp1a.
[0066] Additionally, in some cases, sequence generation can be selected downwards to have a sequence generation scheme for all channels or NR signals, or different sequence generation schemes for different channels or signals.
[0067] According to some implementations,
Petition 870190093060, of 9/17/2019, p. 37/86
33/59 in a dual-band operation of the broadband system using the UE's specific set of BPs, the UE 110 and the base station 105 may be responsible for managing one or more BPs 302 and sub-bands . In some examples, UE 110 and base station 105 may be responsible for managing one or more BPs 302 versus Channel Status Information (CSI) sub-bands or audible reference signal (SRS) sub-bands. For example, CSI measurement, CSI reporting, or SRS transmission can be based on sub-band. In some respects, the limit of a CSI or SRS subband can be aligned with the limit of a corresponding or respective BP 302. In some cases, if the limits may not be aligned, then the UE 110 can eliminate the CSI ( or SRS), or the CSI (or SRS) can be managed for a partial sub-band. That is, for example, the CSI and / or SRS can be transmitted with a subband that comprises two BPs. Alternatively, the CSI and / or the SRS can be partially transmitted only in one of the two adjacent BPs.
[0068] In some respects, sub-band size management can be based on broadband or narrowband bandwidth resources of UE 110. For example, in a first management scheme, same (s) size subband or site (s) can be used for both broadband and narrowband 110 UEs. In a second management scheme, different subband or site sizes can be used used for broadband and 110 narrowband UEs. For example, but not limited to, a broadband UE (for example, broadband UE 304) may be of a size
Petition 870190093060, of 9/17/2019, p. 38/86
34/59 subband of eight (8) resource blocks (RBs), while a first narrowband UE (for example, with 40 MHz maximum channel bandwidth resource) may have a subband size band of 4 RBs, and a second narrowband UE (for example, with maximum channel bandwidth feature of 20 MHz) can have a subband size of 2 RBs. It may be preferable for such subband sizes to be multiples of 2 in order to allow the different combinations to work well together.
[0069] According to some implementations, in dual bandwidth mode operation of the broadband system and when using the specific set of UEs of BPs, downlink (DL) and uplink (UL) 302 in a cell can be managed together or separately. In an example of jointly managed, both DL and UL have 5 BPs, and there is a one-to-one correspondence. In a separate management example, the DL has 5 BPs and the UL has 3 BPs, where the link between DL and UL BPs is indicated by base station 105. For example, base station 105 can transmit a DL BP indicator / UL, as in a SIB.
[0070] In some implementations, the UE 110 can be configured such that the DL and UL have the same capacity. For example, UE 110 can have DL and UL channel bandwidth both at 20 MHz.
[0071] In other implementations, the UE 110 can be configured such that the bandwidth resources of the DL and UL channel are different. In one example, for example, the UE 110 may have 40 MHz DL channel bandwidth and 20 MHz UL channel bandwidth.
Petition 870190093060, of 9/17/2019, p. 39/86
In addition, in some cases, the UE 110 may separately derive the set of BPs for DL and UL.
[0072] With reference to Figures 4 to 10, in an example of operation of an NR 100 wireless communication system, a wireless communication method 400 performed by the UE 110 in accordance with the aspects described above includes one or more of the actions defined here.
[0073] With reference to Figure 4, in an operational aspect, the UE 110 (Figure 1) can perform one or more aspects of a 400 method to perform dual mode operations on a wireless communication network (for example, a network NR technology) having at least one broadband CC. For example, as shown later in Figure 12, one or more of processors 1212, memory 1216, modem 140, transceiver 1202, and / or communication component 150, can be configured to perform one or more aspects of method 400.
[0074] In one aspect, at 402, method 400 includes identifying a system bandwidth value for a cell. For example, in one aspect, UE 110 may perform communication component 150 and / or part of bandwidth determiner 152 to identify a system cell bandwidth value, as described above, and in Figure 2 or Figure 3. For example, a cell or base station 105 can be configured to have at least one value (for example, a frequency range, such as 100 MHz) of the system's bandwidth, which can be used by DL channels / UL or CCs to exchange communications with one or more UEs 110. In some implementations, the UE 110 can identify or
Petition 870190093060, of 9/17/2019, p. 40/86
36/59 determining the system bandwidth value from exchange of communications with base station 105, for example, from a broadcast signal transmitted from base station 105.
[0075]
In one aspect, at 404 method 400 includes identifying a UE bandwidth resource. For example, in one aspect, UE 110 may perform communication component 150 and / or part of bandwidth determiner 152 to identify a UE bandwidth resource. For example, a UE bandwidth resource can be the maximum channel bandwidth that the UE can support, and can be configured to be capable of broadband (e.g., broadband UE 304) or narrowband ( for example, narrowband EU 306 or 308), as described above and in Figure 2 or Figure 3, or based on a wireless communication standard.
[0076]
In one aspect, at 406, method 400 includes determining a specific UE set of parts of the bandwidth each having a specific UE bandwidth based on the system bandwidth value and the bandwidth resource of the UE. For example, in one aspect, UE 110 may perform communication component 150 and / or part of bandwidth determiner 152 to determine a set of parts of the specific bandwidth of the UE (for example, a specific set of the UE of parts of the bandwidth 302 in the
Figure 3), where each part of the bandwidth has a specific bandwidth of the UE based on the system bandwidth value (identified at 402) and the UE bandwidth resource (identified at 404),
Petition 870190093060, of 9/17/2019, p. 41/86
37/59 as described above and in Figure 2 or Figure 3, or based on a wireless communication standard.
[0077] In another aspect, in 408, method 400 may optionally include monitoring the UE's specific set of parts of the bandwidth for communication. For example, in one aspect, UE 110 may perform communication component 150, part of bandwidth determiner 152, and / or transceiver 1202 to monitor one or more signals from cell or base station 105 using at least one of the UE specific set of parts of the bandwidth, as described above and in Figure 2 or Figure 3.
[0078] In one aspect, in 410, method 400 includes communicating with the cell using at least one of the UE's specific set of parts of the bandwidth. For example, in one aspect, UE 110 may perform communication component 150, part-bandwidth controller 154, and / or transceiver 1202 to communicate with cell or base station 105 using at least one of the specific set of UEs. parts of the bandwidth, as described above and in Figure 3. In a dual mode operation, for example, broadband channel 200 can be organized or configured into a set of one or more BPs 302 (for example, 302- a, 302-b, 302-c, and / or 302-d), based on channel 206 bandwidth resource of a respective UE 110. In some cases, UE 110 can be configured to transmit signals to, or receive signals from, base station 105 using one or more BPs 302, based on the system bandwidth value (identified in 042) and the UE bandwidth resource
Petition 870190093060, of 9/17/2019, p. 42/86
38/59 (identified at 404).
[0079] In one example, each of the UE's specific set of parts of the bandwidth has the same bandwidth, at least two of the UE's specific set of parts of the bandwidth have different bandwidths, or some combination or the specific UE set of parts of the bandwidth comprise a single part of the bandwidth having a frequency range substantially corresponding to the system bandwidth value.
[0080] With reference to Figure 5, method 500 can continue from one or more of the method 400 operations in order to be responsible for another signaling in the system bandwidth and / or in one or more of the parts of the width bandwidth 302.
[0081] For example, in 502, method 500 may include determining the presence of at least one of a PBCH or a synchronization signal. For example, in one aspect, UE 110 may perform communication component 150, presence of synchronization of determinator 156, and / or transceiver 1202 to determine presence of at least one of a PBCH or a synchronization signal (e.g., PSS, SSS), as described above and in Figure 3. In some cases, a PBCH or a synchronization signal (for example, PSS, SSS) can be included or displayed in one or more parts of the 302 bandwidth, and can be transmitted from base station 105 to UE 110 on a DL signal. For example, base station 105 can transmit or broadcast a synchronization presence indicator on the DL signal.
Petition 870190093060, of 9/17/2019, p. 43/86
39/59
[0082] In one aspect, in 504, the method 500 can include carry out correspondence in rate for one or more other channels with based on presence in fur any less one of PBCH or signal in synchronization. Per example, in one
aspect, the UE 110 can perform communication component 150 and / or rate matching component 158 and / or modem 140 to perform rate matching for one or more other channels based on the presence of at least one of the physical broadcast channel or the synchronization signal, as described above. In some cases, the synchronization presence indicator discussed above may be a semi-static indication included in a broadcast signal, or it may be a dynamic indication. In one aspect, based on the indicated presence, the UE 110 can perform rate matching for one or more other channels (for example, a PDSCH).
[0083] In some cases, determining the presence of at least one of the physical broadcast channel and the synchronization signal may include detecting at least one of the UE's specific set of parts of the bandwidth. In other cases, determining the presence of at least one of the PBCH or the synchronization signal may further comprise detecting the presence in a first one of the specific UE set of parts of the bandwidth, and may further include performing at least one of a timing tracking or frequency tracking for one or more other channels of a second one of the specific UE set of parts of the bandwidth based on the detection of the presence in the first one of the specific UE set of parts of the bandwidth .
[0084] In some cases, perform
Petition 870190093060, of 9/17/2019, p. 44/86
40/59 rate matching for the one or more other channels of a second one of the specific UE set of bandwidth parts is based on determining the presence in a first one of the specific UE set of bandwidth parts is performed when the presence of at least one of the physical broadcast channel or the synchronization signal is not transmitted by the second one of the UE's specific set of parts of the bandwidth.
[0085] In some cases, determining the presence of at least one of the physical broadcast channel and the synchronization signal may include receiving a presence indicator transmitted by base station 105. For example, this may include receiving a broadcast channel or signal that carries the presence indicator.
[0086] With reference to Figure 6, method 600 can continue from method 400 operations in order to allow UE 110 to improve efficiency or throughput in relation to signaling. For example, in 602, method 600 includes performing aggregation of part of the bandwidth of the specific UE set of parts of the bandwidth. For example, in one aspect, the UE 110 can perform communication component 150, bandwidth portion aggregator 160, modem 140, and / or transceiver 1202 to perform aggregation of part of the bandwidth of the specific set of parts UE bandwidth 302, as described above and in Figure 3. In some examples, the specific UE set of parts of bandwidth 302 that can be aggregated BP may include one of the contiguous intra-bandwidths, bandwidths non-contiguous intra-band, or inter-band, bandwidth
Petition 870190093060, of 9/17/2019, p. 45/86
41/59 not contiguous.
[0087] With reference to Figure 7A, in one aspect, method 700 can continue from one or more of method 400 operations in order to allow UE 110 to manage UL broadband and / or DL signaling. For example, signaling by UE 110 and / or base station 105 may use sequence generation, such as to apply a random sequence that can be used to scramble or unscramble, for a DM-RS modulation sequence, or for channel interleaving , etc. In some instances, sequence generation may be applicable for DL and / or UL channels / signals.
[0088] For example, in 702, method 700 includes determining that a random sequence associated with a received or transmitted signal corresponds to a broadband sequence. For example, in one aspect, UE 110 may perform communication component 150, sequence manager 162, modem 140, and / or transceiver 1202 to determine that a random sequence associated with a received or transmitted signal corresponds to a broadband sequence , as described here. In some cases, the received or transmitted signal may be a reference signal, such as a demodulation reference signal.
[0089] In one aspect, in 704, method 700 may include using a portion of the broadband sequence for at least one of the UE's specific set of parts of the bandwidth. For example, in one aspect, UE 110 can perform communication component 150, sequence manager 162, signaling controller 166, modem
Petition 870190093060, of 9/17/2019, p. 46/86
42/59
140, and / or transceiver 1202 to use a portion of the broadband sequence for at least one of the UE specific set of parts of the bandwidth 302, as described herein.
[0090] With reference to Figure 7B, in another alternative, method 750 can continue from method 400 operations in order to allow UE 110 to manage signal generation and use on a BP basis, which can apply both narrowband UEs as well as broadband UEs. For example, in 752, method 750 includes determining that a random sequence associated with a received or transmitted signal corresponds to a specific sequence of part of the bandwidth. For example, in one aspect, UE 110 may perform communication component 150, sequence manager 162, signaling controller 166, modem 140, and / or transceiver 1202 to determine that a random sequence associated with a received or transmitted signal corresponds to a specific sequence of part of the bandwidth, as described here.
[0091] In an alternative that can be used by a broadband UE (for example, broadband UE 304), in 754, method 750 may include the combination of a respective specific sequence of part of the bandwidth from each of the UE's specific set of parts of the bandwidth to define a broadband sequence. For example, in one aspect, UE 110 may perform communication component 150, sequence manager 162, signaling controller 166, modem 140, and / or transceiver 1202 to match a respective specific sequence of part of the bandwidth from
Petition 870190093060, of 9/17/2019, p. 47/86
43/59
of each the EU's specific set of parts gives width of band to set a sequence band wide, like described here. In others words, the UE in broadband 304 receives or I transmitted strings what are generated in one base per BP can to sew together at respective strings for form a sequence band
wide.
[0092] With reference to Figure 8, in another alternative, method 800 can continue from one or more method 400 operations in order to allow UE 110 to manage the generation and use of sequence in the same way or in different ways. For example, in 802, method 800 includes determining that a broadband-based random sequence or a narrowband-based sequence associated with a received or transmitted signal is used across all channels or signals, or that a random sequence broadband based or a narrow band based sequence associated with a received or transmitted signal is different across different channels or signals. For example, in one aspect, UE 110 can perform communication component 150, sequence manager 162, signaling controller 166, modem 140, and / or transceiver 1202 to determine that a random sequence based on broadband or a sequence with narrowband base associated with a received signal or
transmitted is used through in all the channels or signals, or is different through in many different channels or signals. [0093 ] With reference The Figure 9, in some
aspects concern the configuration of BPs and the configuration
Petition 870190093060, of 9/17/2019, p. 48/86
44/59 sub-bands for other signaling, method 900 may continue from method 400 operations, or be part of a method 400 operation to allow UE 110 to use BPs and other signaling in sub-bands .
[0094] For example, as part of block operation 408, in 902, method 900 can optionally include transmitting or receiving a signal related to the quality of the channel in a frequency sub-band defined within a frequency range limit of one of the UE's specific set of parts of the bandwidth. For example, in one aspect, UE 110 may perform communication component 150, channel quality manager 164, signaling controller 166, modem 140, and / or transceiver 1202 to transmit or receive signaling related to channel quality on a frequency subband defined within a frequency range limit of one of the UE's specific set of parts of the bandwidth.
[0095] In another example, being part of block 408 operation, in 904, method 900 can optionally include transmitting or receiving a signal in a frequency subband, and at least one of a size or location of the subband frequency band being configured for specific UE. For example, in one aspect, UE 110 can perform communication component 150, signaling controller 166, modem 140, and / or transceiver 1202 to transmit or receive a signal in a frequency subband. In some cases, at least one of the frequency subband's size or location is configured for specific UE. In some examples, the size or location of the sub
Petition 870190093060, of 9/17/2019, p. 49/86
45/59 frequency band is constant regardless of the UE's bandwidth resource. In other cases, the size or location of the frequency sub-band is different depending on the UE's bandwidth resource.
[0096] With reference to Figure 10, in some aspects they refer to the configuration of BPs using a reference set of BPs, method 1000 can continue from method 400 operations, or be part of a method 400 operation from to allow the UE 110 to use BPs and other signaling. For example, continuing from block operation 404, at 1002, method 1000 may include determining a reference set of parts of the bandwidth having a reference bandwidth associated with the system bandwidth value. For example, in one aspect, UE 110 may perform communication component 150, and / or part of bandwidth determiner 152 to determine a reference set of parts of bandwidth having a reference bandwidth associated with the system bandwidth value identified in block 402. In one aspect, the specific set of parts of bandwidth UE 302 can be determined based on the reference set of parts of bandwidth.
[0097] In another aspect they refer to the configuration of BPs, method 400 may include determining that the specific set of UE of parts of the bandwidth is the same for DL and UL, or is different. That is, when the UE's specific set of parts of the bandwidth is determined to be the same for DL and UL, it can be
Petition 870190093060, of 9/17/2019, p. 50/86
46/59 paired (for example, 3 BPs of DL and 3 BPs of UL). Conversely, when the UE's specific set of parts of the bandwidth is determined to be different for DL and UL, there will be a first set of BPs for downlink operation, and a second set of BPs, different in number (and / or bandwidth range) from the first set, for uplink operation. For example, in one aspect, the UE 110 may perform communication component 150, part of the bandwidth part 152, and / or part of the bandwidth controller 154 to determine that the specific set of parts of the bandwidth UE band is the same for DL and UL, or is different.
[0098] With reference to Figure 11, in one example, a method 1100 of wireless communications by base station 105 (Figure 1) may include operations complementary to the operations of UE 110 as described above. In an operational aspect, the base station 105 can perform one or more aspects of method 1100 to perform dual mode operations on a wireless communication network (for example, an NR technology network) having at least one broadband DC . For example, as shown later in Figure 13, one or more of processors 1312, memory 1316, modem 170, transceiver 1302, and / or communication component 180, can be configured to perform one or more aspects of method 1100.
[0099] In one aspect, in 1102, for example, method 1100 may include identifying a system bandwidth value for a cell in which a UE is operating. For example, in one aspect, base station 105 can
Petition 870190093060, of 9/17/2019, p. 51/86
47/59 execute communication component 180 and / or part of bandwidth determiner 182 to identify a system bandwidth value of a cell in which the UE 110 is operating, described above, and in Figure 2 or Figure 3 For example, a cell or base station 105 can be configured to have at least one value (for example, a frequency range, such as 100 MHz) of the system's bandwidth, which can be used by DL / UL channels or CCs to exchange communications with one or more UEs 110.
[0100] In one aspect, in 1104, for example, method 1100 may include identifying a bandwidth resource from the UE to the UE. For example, in one aspect, base station 105 may perform communication component 180 and / or part of bandwidth determiner 182 to identify a bandwidth resource from the UE to the UE, as described above. For example, a UE 110 bandwidth resource can be the maximum channel bandwidth that the UE 110 can support, and can be obtained from the UE 110 which is capable of broadband (for example, UE bandwidth wide 304) or narrowband (for example, narrowband EU 306 or 308), as described above and in Figure 2 or Figure 3, or based on a wireless communication standard.
[0101] In one aspect, in 1106, for example, method 1100 may include determining a specific UE set of parts of the bandwidth for the UE, each having a specific bandwidth of the UE based on the width value system bandwidth and UE bandwidth resource. For example, in one aspect, base station 105 can perform communication component

48/59
180, and / or bandwidth part determiner 182 to determine a specific UE set of parts of the bandwidth for the UE, each having a specific bandwidth of the UE based on the system bandwidth value and the UE bandwidth feature, as described above and in Figure 2 or Figure 3, or based on a wireless communication standard.
[0102]
In one aspect, in 1108, for example, method 1100 may include communicating with the UE using at least one of the UE's specific set of parts of the bandwidth. For example, in one aspect, the base station 105 can perform communication component 180, bandwidth portion controller 184, modem 170, and / or transceiver 1302 to communicate (e.g., transmit signaling) with UE 110 at least least one of the UE's specific set of parts of the bandwidth, as described above and in Figure 3. In a dual mode operation, for example, base station 105 can organize or configure broadband channel 200 in a set of one or more BPs 302 (for example, 302-a, 302-b, 302-c, and / or 302-d), based on channel 206 bandwidth resource of a respective UE 110. In some cases, the base station 105 can be configured to transmit signals to, or receive signals from, UE 110 using one or more BPs 302, based on the system bandwidth value (identified at 1102) and the UE bandwidth feature (identified in 1104).

49/59 a PBCH or a synchronization signal on at least one of the UE's specific set of parts of the bandwidth. For example, in one aspect, base station 105 may perform communication component 180, bandwidth portion controller 184, synchronization control manager 186, modem 170, and / or transceiver 1302 to transmit an indication to UE 110 indicating the presence of at least one of a PBCH or a synchronization signal (e.g., PSS, SSS) in at least one of the UE's specific set of parts of the bandwidth, as described here. In some examples, the base station 105 may transmit or broadcast a message including the indication (for example, a synchronization presence indicator). In some cases, the indication may be a semi-static indication included in a broadcast signal, or it may be a dynamic indication. In one implementation, the synchronization control manager 186 can be configured to manage one or more of PBCHs, synchronization channels, and related signaling.
[0104] In another aspect, for example, method 1100 may optionally include determining a reference set of parts of the bandwidth having a reference bandwidth associated with the system bandwidth value.

50/59 [0105] In other alternatives, method 1100 may include additional actions, and base station 105 may include additional components, to manage or control other signaling or configurations based on specific UE set of parts of the bandwidth. Examples of such other apparatus and methods may include a sequence manager 190 to manage generation and use of random sequence, a quality manager of channel 192 to manage configuration and interoperability of specific UE set of parts of the bandwidth with channels and signaling channel quality, or a signaling controller 188 to work with one or more other components to manage any signaling base station.
