[0002] This patent application claims priority to Indian Provisional Patent Application No. 202041035559, filed on August 18, 2020, entitled “ADJUSTING DATA SPLIT BETWEENNEW RADIO CHANNELS AND LEGACY CHANNELS,” which has been assigned to the assignee of this application. The disclosure of the prior application is considered part of this patent application and is incorporated herein by reference. Technical Field

[0003] Various aspects of this disclosure generally relate to wireless communication, and specifically to techniques and apparatus for adjusting data segmentation between new radio channels and traditional channels. Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that enable communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include multiple base stations (BSs) capable of supporting communication for multiple user equipments (UEs). UEs can communicate with the BS via downlinks and uplinks. A "downlink" (or forward link) refers to the communication link from the BS to the UE, and an "uplink" (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, Access Point (AP), Radio Head, Transmit / Receive Point (TRP), New Radio (NR) BS, 5G Node B, etc.

[0006] The aforementioned multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different user equipment to communicate at the city, country, region, or even global level. NR, also known as 5G, is a set of enhancements to the LTE mobile standard issued by 3GPP. NR is designed to better support mobile broadband internet access by improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and better integrating with other open standards. These open standards use Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) (CP-OFDM) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Spread Spectrum OFDM (DFT-s-OFDM)) on the uplink (UL), and support beamforming, multiple-input multiple-output (MIMO) antenna technologies, and carrier aggregation. Further improvements to LTE, NR, and other radio access technologies remain highly valuable as the demand for mobile broadband access continues to grow. Summary of the Invention

[0032] Various aspects of this disclosure will be described more fully below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided to make this disclosure thorough and complete, and to fully convey the scope of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art should understand that the scope of this disclosure is intended to cover any aspect disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or practice. Furthermore, the scope of this disclosure is intended to cover an apparatus or method practiced using structures, functions, or structures and functions other than those set forth herein. It should be understood that any aspect of the disclosure herein may be embodied by one or more elements of the claims.

[0033] Several aspects of a telecommunications system will now be described with reference to various devices and technologies. These devices and technologies will be described in detail below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, “elements”). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented in hardware or software depends on the specific application and the design constraints on the overall system.

[0034] It should be noted that although the terms commonly associated with 5G or NR radio access technology (RAT) may be used to describe the aspects herein, the aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or RATs after 5G (e.g., 6G).

[0035] Figure 1This is a schematic diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, etc. The wireless network 100 may include multiple base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, Transmit / Receive Point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of ​​a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0036] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access for UEs with service subscriptions. A picocell can cover a relatively small geographic area and can allow unrestricted access for UEs with service subscriptions. A femtocell can cover a relatively small geographic area (e.g., a home) and can allow restricted access for UEs associated with that femtocell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS used for macrocells can be referred to as a macro BS. A BS used for picocells can be referred to as a pico BS. A BS used for femtocells can be referred to as a femtocell BS or a home BS. Figure 1 In the example shown, BS 110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for pico cell 102b, and BS 110c can be a femto BS for femto cell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “Node B,” “5G NB,” and “cell” are used interchangeably herein.

[0037] In some respects, the cell is not necessarily stationary, and the geographical area of ​​the cell can move depending on the location of the mobile BS. In some respects, BSs can use any suitable transport network to interconnect with each other and / or interconnect to one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces, such as direct physical connections or virtual networks.

[0038] The wireless network 100 may also include relay stations. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send data transmissions to a downstream station (e.g., a UE or a BS). A relay station can also be a UE capable of relaying transmissions for other UEs. Figure 1 In the example shown, relay BS110d can communicate with macro BS110a and UE 120d to facilitate communication between BS110a and UE 120d. A relay BS can also be referred to as a relay station, relay base station, relay, etc.

[0039] Wireless network 100 can be a heterogeneous network, including different types of base stations (BSs), such as macro BSs, pico BSs, femto BSs, and relay BSs. These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs may have high transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1 to 2 watts).

[0040] Network controller 130 can be coupled to a group of base stations (BSs) and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via backhaul. The BSs can also communicate with each other directly or indirectly, for example, via wireless or wired backhaul.

[0041] UEs 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be fixed or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. A UE may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biosensor / device, a wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0042] Some UEs can be considered Machine-Type Communication (MTC) or Evolved or Enhanced Machine-Type Communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that can communicate with base stations, another device (e.g., a remote device), or some other entity. For example, a wireless node can provide connectivity to or to a network (e.g., a wide area network such as the Internet or a cellular network) via wired or wireless communication links. Some UEs can be considered Internet of Things (IoT) devices, and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered Customer Premises Equipment (CPE). UE 120 can be included within a housing that houses the components of UE 120, such as processor components and / or memory components. In some aspects, the processor components and memory components can be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0043] Typically, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, air interface, etc. A frequency can also be referred to as a carrier, channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0044] In some respects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as a medium for communication with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols) and / or mesh networks. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations performed by base station 110 as described elsewhere herein.

[0045] Devices of wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices of wireless network 100 may communicate using an operating band with a first frequency range (FR1) from 410 MHz to 7.125 GHz, and / or may communicate using an operating band with a second frequency range (FR2) from 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as intermediate frequency (IF) bands. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as the “sub-6 GHz” band. Similarly, FR2 is often referred to as the “millimeter wave” band, although it differs from the extremely high frequency (EHF) band (30 GHz–300 GHz) designated as the “millimeter wave” band by the International Telecommunication Union (ITU). Therefore, unless specifically stated otherwise, it should be understood that the terms “sub-6 GHz”, etc., if used herein, may broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or intermediate frequency bands (e.g., greater than 7.125 GHz). Similarly, unless otherwise stated, it should be understood that the terms "millimeter wave," etc., if used herein, can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or intermediate frequency band frequencies (e.g., less than 24.25 GHz). It is anticipated that the frequencies included in FR1 and FR2 may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0046] As mentioned above, Figure 1 This is provided as an example. Other examples may differ from those provided. Figure 1 As described.

[0047] Figure 2 This is a schematic diagram illustrating an example 200 of a base station 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, wherein typically T ≥ 1 and R ≥ 1.

[0048] At base station 110, transmitting processor 220 can receive data for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQI) received from the UE, process (e.g., encode and modulate) the UE's data based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. Transmitting processor 220 can also process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper-layer signaling), and provide overhead symbols and control symbols. Transmitting processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols (if applicable), and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can process its corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t can be transmitted via T antennas 234a to 234t, respectively.

[0049] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations, and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can adjust (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM) to obtain received symbols. MIMO detector 256 can obtain the received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols if applicable, and provide the detected symbols. Receive processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine parameters such as the Received Reference Signal Power (RSRP), Received Signal Strength Indicator (RSSI), Received Reference Signal Quality (RSRQ), and / or CQI. In some respects, one or more components of the UE 120 may be included in the housing 284.

[0050] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0051] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included in one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements coupled to one or more transmitting and / or receiving components (such as...) Figure 2 One or more antenna elements (one or more components).

[0052] On the uplink, at UE 120, the transmitting processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting RSRP, RSSI, RSRQ, and / or CQI). The transmitting processor 264 can also generate reference symbols for one or more reference signals. If applicable, the symbols from the transmitting processor 264 can be pre-encoded by TX MIMO processor 266, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some aspects, the modulator and demodulator of UE 120 (e.g., MOD / DEMOD 254) can be included in the modem of UE 120. In some aspects, UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, modulator and / or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The processor (e.g., controller / processor 280) and memory 282 may be used with the transceiver to perform aspects of any of the methods described herein (e.g., references...). Figures 4-8 ).

[0053] At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if applicable), and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide decoded data to data sink 239 and decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 for scheduling downlink and / or uplink communications of UE 120. In some aspects, modulators and demodulators (e.g., MOD / DEMOD 232) of base station 110 may be included in the modem of base station 110. In some aspects, base station 110 includes transceivers. The transceiver may include any combination of antenna(s) 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The processor (e.g., controller / processor 240) and memory 242 may be used with the transceiver to perform aspects of any of the methods described herein (e.g., references...). Figures 4-8 ).

[0054] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120 and / or Figure 2 Any other component(s) may perform one or more techniques associated with adjusting the data segmentation between the NR channel and the legacy channel, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component (or multiple components) can perform or direct, for example... Figure 5 Process 500 Figure 6 Process 600 Figure 7 Process 700 Figure 8 The operation of process 800 and / or other processes described herein. Memory 242 and 282 may store data and program code of base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly executed, or executed after compilation, transformation, and / or interpretation), may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example...

In some aspects, execution instructions may include run instructions, translation instructions, compilation instructions, and / or interpretation instructions, etc.

[0055] In some aspects, the UE (e.g., UE 120) may include components for receiving an indicator of data segmentation between an NR channel and a legacy channel from a base station (e.g., base station 110); and / or components for transmitting a modified indicator of data segmentation to the base station based at least in part on the ratio of the amount of data flowing on the NR channel to the total amount of data flowing on the NR channel and the legacy channel. Components for the UE to perform the operations described herein may include one or more of, for example, antenna 252, demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, modulator 254, controller / processor 280, or memory 282.

[0056] In some aspects, a base station (e.g., base station 110) may include components for transmitting an indicator of data segmentation between an NR channel and a legacy channel to a UE (e.g., UE 120); and / or components for receiving a modified indicator of data segmentation from the UE based at least in part on the ratio of the amount of data flowing on the NR channel to the total amount of data flowing on both the NR channel and the legacy channel. Components for the base station to perform the operations described herein may include one or more of, for example, a transmit processor 220, a TX MIMO processor 230, a modulator 232, an antenna 234, a demodulator 232, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0057] In some aspects, the UE (e.g., UE 120) may include components for receiving an indicator of data segmentation between an NR channel and a legacy channel from a base station (e.g., base station 110); and / or components for transmitting a modified indicator of the data segmentation to the base station, at least in part based on an indicator of the quality of the legacy channel. Components for the UE to perform the operations described herein may include one or more of, for example, antenna 252, demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, TXMIMO processor 266, modulator 254, controller / processor 280, or memory 282.

[0058] In some aspects, a base station (e.g., base station 110) may include components for transmitting an indicator to a UE (e.g., UE 120) of a data segmentation between an NR channel and a legacy channel; and / or components for receiving a modified indicator of the data segmentation from the UE, at least in part based on an indicator of the quality of the legacy channel. Components for the base station to perform the operations described herein may include one or more of, for example, a transmit processor 220, a TX MIMO processor 230, a modulator 232, an antenna 234, a demodulator 232, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0059] Although Figure 2 The boxes in the diagram are shown as different components, but the functions described above for each box can be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described for the transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be performed by or under the control of the controller / processor 280.

[0060] As mentioned above, Figure 2 This is provided as an example. Other examples may differ from those provided. Figure 2 As described.

[0061] Figure 3 This is a schematic diagram illustrating an example 300 of an antenna port according to this disclosure. Figure 3 As shown, the first physical antenna 305-1 can transmit information via the first channel h1, the second physical antenna 305-2 can transmit information via the second channel h2, the third physical antenna 305-3 can transmit information via the third channel h3, and the fourth physical antenna 305-4 can transmit information via the fourth channel h4. Such information can be transmitted via logical antenna ports, which can represent a certain combination of physical antennas and / or channels. In some cases, the UE 120 may not know the channels associated with the physical antennas and may operate solely based on knowledge of the channels associated with the antenna ports, as defined below.

[0062] Antenna ports can be defined such that the channel transmitting symbols on that antenna port can be inferred from the channel transmitting another symbol on the same antenna port. In Example 300, the channel associated with antenna port 1 (AP1) is represented as h1-h2+h3+j*h4, where the channel coefficients (e.g., 1, -1, 1, and j in this case) represent weighting factors applied to each channel (e.g., indicating phase and / or gain). Such weighting factors can be applied to the channels to improve signal power and / or signal quality at one or more receivers. Applying such weighting factors to channel transmission can be called precoding, and a precoder can refer to a specific set of weighting factors applied to a set of channels.

[0063] Similarly, the channel associated with antenna port 2 (AP2) is represented as h1 + j * h3, and the channel associated with antenna port 3 (AP3) is represented as 2 * h1 - h2 + (1 + j) * h3 + j * h4. In this case, antenna port 3 can be represented as the sum of antenna port 1 and antenna port 2 (e.g., AP3 = AP1 + AP2), because the sum of the expression representing antenna port 1 (h1 - h2 + h3 + j * h4) and the expression representing antenna port 2 (h1 + j * h3) equals the expression representing antenna port 3 (2 * h1 - h2 + (1 + j) * h3 + j * h4). Alternatively, antenna port 3 can be said to be associated with antenna ports 1 and 2 [AP1, AP2] via the precoder [1, 1], because multiplying the expression representing antenna port 1 by 1 and adding the expression representing antenna port 2 by 1 equals the expression representing antenna port 3.

[0064] As mentioned above, Figure 3 Provided as an example only. Other examples may differ from those provided. Figure 3 As described.

[0065] In some cases, the UE can support concurrent operation on NR channels and legacy channels (e.g., LTE channels, 4G channels, 3G channels, and / or another channel that is legacy relative to the NR channel). Furthermore, the UE can use antenna switching (e.g., using multiple antenna ports, as combined above). Figure 3 As described, this includes 1T4R antenna switching (e.g., one sounding reference signal (SRS) port has corresponding SRS resources for four SRS resources, and each SRS resource is associated with a different antenna port of the UE) and / or another type of antenna switching. For example, on an evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (RAN) (also known as E-UTRAN), the UE may support band N41 (e.g., approximately 2496-2690MHz) and / or another similar band on the NR channel, combined with band B3 (e.g., approximately 1800MHz) and / or another similar band on the LTE channel. In another example, on EUTRAN, the UE may support band N41 (e.g., approximately 2496-2690MHz) and / or another similar band on the NR channel, combined with band B39 (e.g., approximately 1900MHz) and / or another similar band on the LTE channel.

[0066] However, to support antenna switching on the NR channel (e.g., 1T4R antenna switching), the UE typically blanks the reception and / or transmission timings on the legacy channel during SRS reception and / or transmission on the NR channel. This is because the UE antenna ports used on the NR channel often conflict with the ports required for reception and / or transmission on the legacy channel, or both. However, when the UE blanks the legacy channel, it suffers a reduction in communication quality and / or reliability.

[0067] Some of the techniques and apparatus described herein enable a UE (e.g., UE 120) to dynamically segment data between NR and traditional channels, at least in part based on the ratio of the amount of data flowing on the NR channel to the total amount of data flowing on the NR channel and / or at least in part based on the conditions of the traditional channel. Therefore, UE 120 can improve the quality and / or reliability of communication with a base station (e.g., base station 110) by modifying the data segmentation between the NR and traditional channels. For example, when blanking the traditional channel, UE 120 can request additional resources for the NR channel. As a result, UE 120 increases throughput, quality, and / or reliability on the NR channel. Alternatively, UE 120 can degrade the NR channel while suppressing blanking of the traditional channel (e.g., from 1T4R to 1T2R, where one SRS port has corresponding SRS resources in two SRS resources, and each SRS resource is associated with a different antenna port of UE 120). As a result, UE 120 improves quality and / or reliability on the traditional channel.

[0068] Figure 4 This is a schematic diagram illustrating Example 400 related to adjusting the data segmentation between the NR channel and the traditional channel according to this disclosure. Figure 4 As shown, Example 400 includes communication between base station 110 and UE 120. In some aspects, base station 110 and UE 120 may be included in a wireless network, such as wireless network 100. Base station 110 and UE 120 may communicate on a radio access link, which may include an uplink and a downlink.

[0069] In some aspects, base station 110 and UE 120 can communicate on NR channels as well as legacy channels (e.g., LTE channels, 4G channels, 3G channels, and / or another channel that is legacy relative to the NR channel). Therefore, base station 110 and UE 120 can be dual-connected (e.g., in E-UTRAN NR Dual Connectivity (ENDC) mode and / or another dual-connectivity mode). In some aspects, the NR channels and legacy channels may include a downlink channel from base station 110 to UE 120. Additionally or alternatively, the NR channels and legacy channels may include an uplink channel from UE 120 to base station 110.

[0070] In some respects, legacy channels may include LTE channels. Although the following description will focus on LTE channels, the description is equally applicable to other legacy channels, such as 4G and / or 3G channels.

[0071] As shown in conjunction with reference numeral 405, base station 110 can transmit, and UE 120 can receive, an indicator for data splitting between the NR channel and the LTE channel. In some aspects, the indicator can be explicit. For example, the indicator may include a UL-DataSplitThreshold variable and / or another similar variable (e.g., as defined in a 3GPP specification and / or another standard) for splitting uplink and / or downlink data between the NR channel and the LTE channel. Additionally or alternatively, the indicator can be implicit. For example, the amount of resources authorized by base station 110 to UE 120 on the downlink channel and / or uplink channel may implicitly split downlink and / or uplink data between the NR channel and the LTE channel (e.g., at least in part based on the amount of NR resources authorized by base station 110 compared to the amount of LTE resources authorized by base station 110).

[0072] As shown in conjunction with reference to reference numeral 410 in the accompanying drawings, UE 120 can determine whether to blank the LTE channel. UE 120 can perform this determination based at least in part on the ratio of the amount of data flowing on the NR channel to the total amount of data flowing on the NR channel and the LTE channel; the number of downlink layers on the NR channel; and / or indicators of the quality of the LTE channel (e.g., signal-to-noise ratio (SNR), signal-to-interference-and-noise ratio (SINR), and / or another quality indicator).

[0073] In some respects, UE 120 may blank the LTE channel when the ratio meets the data threshold. In some respects, UE 120 may be programmed and / or otherwise pre-configured with the data threshold (e.g., according to 3GPP specifications and / or another standard). Additionally or alternatively, UE 120 may dynamically determine the data threshold. For example, UE 120 may adjust the data threshold at least in part based on the number of downlink layers on the NR channel (e.g., decreasing the data threshold when the number of downlink layers is large and increasing the data threshold when the number of downlink layers is small), and / or at least in part based on indicators of LTE channel quality (e.g., increasing the data threshold when the LTE channel quality is high and decreasing the data threshold when the LTE channel quality is low). Similarly, when the ratio does not meet the data threshold, UE 120 may degrade the NR channel (e.g., from 1T4R to 1T2R).

[0074] Additionally or alternatively, UE 120 may blank the LTE channel when the number of downlink layers on the NR channel meets the layer threshold. In some aspects, UE 120 may be programmed with and / or otherwise pre-configured with layer thresholds (e.g., according to 3GPP specifications and / or another standard). Additionally or alternatively, UE 120 may dynamically determine the layer threshold. For example, UE 120 may adjust the layer threshold at least in part based on the ratio of the amount of data flowing on the NR channel to the total amount of data flowing on both the NR and LTE channels (e.g., decreasing the layer threshold when the ratio is high and increasing the layer threshold when the ratio is low), and / or at least in part based on indicators of LTE channel quality (e.g., increasing the layer threshold when the LTE channel quality is high and decreasing the layer threshold when the LTE channel quality is low). Similarly, when the number of downlink layers on the NR channel does not meet the layer threshold, UE 120 may downgrade the NR channel (e.g., downgrade from 1T4R to 1T2R).

[0075] Additionally or alternatively, UE 120 may blank the LTE channel when the quality indicator of the LTE channel does not meet the quality threshold. In some aspects, UE 120 may be programmed with and / or otherwise pre-configured with the quality threshold (e.g., according to 3GPP specifications and / or another standard). Additionally or alternatively, UE 120 may dynamically determine the quality threshold. For example, UE 120 may adjust the quality threshold at least in part based on the ratio of the amount of data flowing on the NR channel to the total amount of data flowing on the NR and LTE channels (e.g., increasing the quality threshold when the ratio is large and decreasing the quality threshold when the ratio is small) and / or at least in part based on the number of uplink and downlink layers of the NR channel (e.g., increasing the quality threshold when the number of downlink layers is large and decreasing the quality threshold when the number of downlink layers is small). Similarly, when the quality indicator of the LTE channel meets the quality threshold, UE 120 may degrade the NR channel (e.g., downgrade from 1T4R to 1T2R).

[0076] Any of the above conditions can be combined. In addition to, or instead of, the above combinations, the AND operator can be used to connect some or all of the above conditions. For example, UE 120 can blank the LTE channel when the number of downlink layers on the NR channel meets a layer threshold and the ratio of the amount of data flowing on the NR channel to the total amount of data flowing on the NR and LTE channels meets a data threshold. Otherwise, UE 120 can downgrade the NR channel (e.g., from 1T4R to 1T2R). In another example, UE 120 can blank the LTE channel when the number of downlink layers on the NR channel meets a layer threshold and the quality indicator of the LTE channel does not meet a quality threshold. Otherwise, UE 120 can downgrade the NR channel (e.g., from 1T4R to 1T2R). In yet another example, UE 120 can blank the LTE channel when the ratio of the amount of data flowing on the NR channel to the total amount of data flowing on the NR and LTE channels meets a data threshold and the quality indicator of the LTE channel does not meet a quality threshold. Otherwise, UE 120 can downgrade the NR channel (e.g., from 1T4R to 1T2R).

[0077] Additionally, or alternatively, some or all of the above conditions may be connected using the OR operator. For example, UE 120 may blank the LTE channel when the number of downlink layers on the NR channel meets a layer threshold or the ratio of the amount of data flowing on the NR channel to the total amount of data flowing on the NR and LTE channels meets a data threshold. Otherwise, UE 120 may downgrade the NR channel (e.g., from 1T4R to 1T2R). In another example, UE 120 may blank the LTE channel when the number of downlink layers on the NR channel meets a layer threshold or the quality indicator of the LTE channel does not meet a quality threshold. Otherwise, UE 120 may downgrade the NR channel (e.g., from 1T4R to 1T2R). In yet another example, UE 120 may blank the LTE channel when the ratio of the amount of data flowing on the NR channel to the total amount of data flowing on the NR and LTE channels meets a data threshold or the quality indicator of the LTE channel does not meet a quality threshold. Otherwise, UE 120 can downgrade the NR channel (e.g., from 1T4R to 1T2R).

[0078] In some respects, one or more of the above conditions may take precedence over one or more of the other conditions. For example, when the quality indicator of the LTE channel meets a quality threshold, UE 120 may downgrade the NR channel (e.g., from 1T4R to 1T2R). Otherwise, UE 120 may still downgrade the NR channel (e.g., from 1T4R to 1T2R) when the number of downlink layers on the NR channel does not meet a layer threshold and / or the ratio of the amount of data flowing on the NR channel to the total amount of data flowing on the NR and LTE channels does not meet a data threshold. In another example, UE 120 may blank the LTE channel when the number of downlink layers on the NR channel meets a layer threshold and the ratio of the amount of data flowing on the NR channel to the total amount of data flowing on the NR and LTE channels meets a data threshold. Otherwise, UE 120 may still blank the LTE channel when the quality indicator of the LTE channel does not meet a quality threshold.

[0079] Based at least in part on the determinations described above in conjunction with reference numeral 410, UE 120 can transmit and base station 110 can receive an indicator for data segmentation modification. In some aspects, the modification indicator may include a UECapabilityMessage (e.g., as defined by 3GPP specifications and / or another standard) or another similar capability message indicating that UE 120 does not have 1T4R capability for the NR channel, but has 1T2R capability for the NR channel.

[0080] Therefore, in some aspects, the modified indicator can enable base station 110 to degrade the capabilities associated with the NR channel and / or enable UE 120 to operate without blanking the legacy channel. In some aspects, as shown in conjunction with reference numeral 415a, the modified indicator may include a Tracking Area Update (TAU). Thus, in response to the TAU, base station 110 can reconstruct the degraded NR channel with UE 120. By degrading this capability, UE 120 can eliminate conflicts between the UE antenna ports used by the NR channel and those ports required for LTE channel reception, transmission, or both. As a result, the quality and / or reliability on the LTE channel increases, which saves network resources and the power and processing resources consumed by UE 120 for the LTE channel.

[0081] As an alternative, and as illustrated by reference numeral 415b in the accompanying drawings, the modified indicator allows UE 120 to transmit more data on the NR channel and operate in the case of blanking the LTE channel. For example, the modified indicator may include at least one of a modified Buffer Status Report (BSR), a request from base station 110 for one or more additional uplink grants, or a combination thereof. Thus, UE 120 may send a modified BSR to base station 110 to indicate that UE 120 is requesting additional data on the NR channel and less data on the LTE channel. Additionally or alternatively, UE 120 may send one or more grant requests to base station 110 for additional resources on the NR channel to increase throughput on the NR channel, such that the increased throughput compensates for LTE blanking. As a result, the increased throughput on the NR channel reduces latency on the NR channel.

[0082] By using combination Figure 4 According to the described techniques, UE 120 can improve the quality and / or reliability of communication with base station 110 by modifying the data segmentation between the NR channel and the LTE channel. For example, as described above in conjunction with reference numeral 415b, when blanking the LTE channel, UE 120 can request additional resources for the NR channel, which increases throughput and reduces latency on the NR channel. Alternatively, and as described above in conjunction with reference numeral 415a, when suppressing blanking the LTE channel, UE 120 can degrade the NR channel (e.g., from 1T4R to 1T2R), which increases the quality and / or reliability on the LTE channel.

[0083] As mentioned above, Figure 4 This is provided as an example. Other examples may differ from those provided. Figure 4 As described.

[0084] Figure 5 This is a schematic diagram illustrating an example process 500 performed by a UE, for example, according to the present disclosure. Example process 500 is an example of an operation performed by a UE (e.g., UE 120) associated with adjusting the data segmentation between the NR channel and the legacy channel.

[0085] like Figure 5 As shown, in some aspects, process 500 may include receiving an indicator of data segmentation between the NR channel and the legacy channel from a base station (e.g., base station 110) (block 510). For example, as described herein, the UE (e.g., using antenna 252, demodulator 254, MIMO detector 256, receive processor 258, controller / processor 280, and / or memory 282) may receive the indicator of data segmentation between the NR channel and the legacy channel from the base station.

[0086] like Figure 5 As further illustrated herein, in some aspects, process 500 may include sending an indication of data segmentation modification to the base station (box 520) based at least in part on the ratio of the amount of data flowing on the NR channel to the total amount of data flowing on the NR channel and the legacy channel. For example, as described herein, the UE (e.g., using antenna 252, transmit processor 264, TX MIMO processor 266, modulator 254, controller / processor 280, and / or memory 282) may send the indication of data segmentation modification to the base station based at least in part on the ratio of the amount of data flowing on the NR channel to the total amount of data flowing on the NR channel and the legacy channel.

[0087] Process 500 may include additional aspects, such as any single aspect or any combination of aspects described below, and / or in conjunction with one or more other processes described elsewhere herein.

[0090] In a third aspect, either alone or in combination with one or more of the first and second aspects, the modified indicator enables the base station to degrade (e.g., using transmit processor 220, TX MIMO processor 230, modulator 232, antenna 234, demodulator 232, MIMO detector 236, receive processor 238, controller / processor 240, memory 242 and / or scheduler 246) the ability to associate with the NR channel, and enables the UE to operate without blanking the traditional channel (e.g., using antenna 252, demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, modulator 254, controller / processor 280 and / or memory 282).

[0094] In the seventh aspect, alone or in combination with one or more of the first to sixth aspects, the modified indicator includes TAU.

[0095] In the eighth aspect, either alone or in combination with one or more of the first to seventh aspects, the indicator for the modification of data segmentation is also at least partially based on an indicator for the quality of the conventional channel.

[0096] although Figure 5 An example box of process 500 is shown, but in some respects, process 500 may include more than Figure 5 The boxes depicted may include more boxes, fewer boxes, different boxes, or boxes arranged differently. Additionally or alternatively, two or more boxes in process 500 may be executed in parallel.

[0097] Figure 6 This is a schematic diagram illustrating an example process 600 performed by a base station according to the present disclosure, for example. Example process 600 is an example of an operation performed by a base station (e.g., base station 110) associated with adjusting data segmentation between NR channels and legacy channels.

[0098] like Figure 6 As shown, in some aspects, process 600 may include sending an indicator (block 610) to the UE (e.g., UE 120) indicating a data segmentation between the NR channel and the legacy channel. For example, as described herein, a base station (e.g., using a transmit processor 220, a TX MIMO processor 230, a modulator 232, an antenna 234, a controller / processor 240, a memory 242, and / or a scheduler 246) may send the indicator to the UE indicating a data segmentation between the NR channel and the legacy channel.

[0099] like Figure 6As further illustrated herein, in some aspects, process 600 may include receiving an indicator of data segmentation modification from the UE (box 620) based at least in part on the ratio of the amount of data flowing on the NR channel to the total amount of data flowing on the NR channel and the legacy channel.

[0100] Process 600 may include additional aspects, such as any single aspect or any combination of aspects described below, and / or in conjunction with one or more other processes described elsewhere herein.

[0101] In the first aspect, NR channels and traditional channels include downlink channels.

[0110] Figure 7 This is a schematic diagram illustrating an example process 700 performed by a UE, for example, according to the present disclosure.
