[0002] This patent application claims priority to U.S. Provisional Patent Application No. 63 / 198,382, filed October 14, 2020, entitled “TECHNIQUES FOR UPLINK COMMUNICATION REROUTING IN A USER EQUIPMENT”, and U.S. Non-Provisional Patent Application No. 17 / 450,638, filed October 12, 2021, entitled “TECHNIQUES FOR UPLINK COMMUNICATION REROUTING IN AUSER EQUIPMENT”, which are expressly incorporated herein by reference. Technical Field

[0003] Various aspects of this disclosure generally relate to wireless communications, and specifically to techniques and apparatus for rerouting uplink communications in a user equipment. Background Technology

[0004] Wireless communication systems have been 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 support 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 / Improved LTE 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 communication network may include one or more base stations that support communication for user equipment (UE) or multiple UEs. UEs may communicate with base stations via downlink and uplink communication. "Downlink" (or "DL") refers to the communication link from the base station to the UE, and "uplink" (or "UL") refers to the communication link from the UE to the base station.

[0006] The above multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different UEs to communicate across city, country, region, and / or global areas. New Radio (NR) (which can also be referred to as 5G) is an enhancement set of the LTE mobile standard issued by 3GPP. NR is designed to better support mobile broadband internet access by improving spectral efficiency, reducing costs, enhancing service, fully utilizing new spectrum, and using Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) on the downlink (CP-OFDM), and using CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Spread Spectrum OFDM (DFT-s-OFDM)) on the uplink (and supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation). Further improvements in LTE, NR, and other radio access technologies remain useful as the demand for mobile broadband access continues to increase. Summary of the Invention

[0045] Various aspects of this disclosure are 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 being limited to any particular structure or function given herein. Rather, these aspects are provided so that this disclosure will be comprehensive and complete, and will fully convey the scope of this disclosure to those skilled in the art. Those skilled in the art will recognize that the scope of this disclosure is intended to cover any aspect of the disclosure herein, whether implemented independently of or in combination with any other aspect of this disclosure.

It should be understood that any aspect of the disclosure herein may be embodied by one or more elements of the claims.

[0046] Several aspects of a telecommunications system will now be described with reference to various devices and techniques. These devices and techniques will be described in the following detailed embodiments and illustrated in the accompanying drawings through various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, “elements”). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented in hardware or software depends on the specific application and the design constraints imposed on the entire system.

[0047] Although the terms commonly associated with 5G or New Radio (NR) Radio Access (RAT) technologies may be used to describe the aspects herein, the aspects of this disclosure may be applied to other RATs, such as 3GRAT, 4GRAT, and / or RATs after 5G (e.g., 6G).

[0048] Figure 1This is a diagram illustrating an example of a wireless network 100 according to this disclosure. Wireless network 100 may be or may include elements of a 5G (e.g., NR) network and / or a 4G (e.g., LTE) network, etc. Wireless network 100 may include one or more base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other network entities. Base station 110 is the entity that communicates with UE 120. Base station 110 (sometimes referred to as BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and / or a Transmit / Receive Point (TRP). Each base station 110 may provide communication coverage for a specific geographic area. In the 3rd Generation Partnership Project (3GPP), the term “cell” can refer to the coverage area of ​​base station 110 and / or the base station subsystem serving that coverage area, depending on the context in which the term is used.

[0049] Base station 110 can provide communication coverage for macro cells, pico cells, femtocells, and / or another type of cell. A macro cell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UE 120 with a service subscription. A pico cell can cover a relatively small geographic area and can allow unrestricted access by UE 120 with a service subscription. A femtocell can cover a relatively small geographic area (e.g., a home) and can allow restricted access by UE 120 associated with the femtocell (e.g., UE 120 in a Closed Subscriber Group (CSG)). Base station 110 for macro cells can be referred to as a macro base station. Base station 110 for pico cells can be referred to as a pico base station. Base station 110 for femtocells can be referred to as a femtocell or a home base station. Figure 1 In the example shown, BS 110a can be a macro base station for macro cell 102a, BS 110b can be a pico base station for pico cell 102b, and BS 110c can be a femto base station for femto cell 102c. A base station can support one or more (e.g., three) cells.

[0050] In some examples, the cell may not necessarily be stationary, and the geographical area of ​​the cell may move depending on the location of the mobile base station 110 (e.g., a mobile base station). In some examples, base station 110 may interconnect with each other and / or interconnect to one or more other base stations 110 or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (such as direct physical connections or virtual networks) using any suitable transport network.

[0051] Wireless network 100 may include one or more relay stations. A relay station is an entity that can receive data transmissions from an upstream station (e.g., base station 110 or UE 120) and transmit data transmissions to a downstream station (e.g., UE 120 or base station 110). A relay station may be a UE 120 capable of relaying transmissions to other UEs 120. Figure 1 In the example shown, BS 110d (e.g., a relay base station) can communicate with BS 110a (e.g., a macro base station) and UE 120d to facilitate communication between BS 110a and UE 120d. The base station 110 for relay communication can be referred to as a relay station, relay base station, repeater, etc.

[0052] Wireless network 100 can be a heterogeneous network comprising different types of base stations 110 (such as macro base stations, pico base stations, femto base stations, relay base stations, etc.). These different types of base stations 110 can have different transmit power levels, different coverage areas, and / or different effects on interference in wireless network 100. For example, macro base stations can have high transmit power levels (e.g., 5 to 40 watts), while pico base stations, femto base stations, and relay base stations can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0053] Network controller 130 may be coupled to or communicate with a set of base stations 110, and may provide coordination and control for these base stations 110. Network controller 130 may communicate with base stations 110 via backhaul communication links. Base stations 110 may communicate directly or indirectly with each other via wireless or wired backhaul communication links.

[0054] UE 120 may be distributed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, access terminals, terminals, mobile stations, and / or subscriber units. UE 120 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 device, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, and / or any other suitable device configured to communicate via a wireless medium.

[0055] Some UEs 120 may be considered Machine-Type Communication (MTC) or Evolved or Enhanced Machine-Type Communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that can communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (Narrowband IoT) devices. Some UEs 120 may be considered customer premises equipment. UE 120 may be included within a housing that houses the components of UE 120, such as processor components and / or memory components. In some examples, the processor components and memory components may be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0056] Typically, any number of wireless networks 100 can be deployed in a given geographical area. Each wireless network 100 can support a specific RAT and can operate on one or more frequencies. A RAT can be referred to as a radio technology, air interface, etc. A frequency can be referred to as a carrier, frequency 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.

[0057] In some examples, 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 an intermediary for communication with each other). For example, UEs 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), vehicle-to-infrastructure (V2I), or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations performed by base station 110 as described elsewhere herein.

[0058] Devices in Wireless Network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., by frequency or wavelength. For example, devices in Wireless Network 100 can communicate using one or more operating frequency bands. In 5G NR, two initial operating frequency bands have been designated as frequency ranges FR1 (410MHz-7.125GHz) and FR2 (24.25GHz-52.6GHz). It should be understood that although a portion of FR1 is greater than 6GHz, FR1 is often referred to (interchangeably) as the “sub-6GHz” band in various documents and articles. Similar naming issues sometimes arise regarding FR2, which is often (interchangeably) referred to as the “millimeter wave” band in literature and articles, although this differs from the Extremely High Frequency (EHF) band (30GHz-300GHz) designated as a “millimeter wave” band by the International Telecommunication Union (ITU).

[0059] The frequencies between FR1 and FR2 are generally referred to as intermediate frequency (IF) bands. Recent 5G NR studies have designated these IF bands as the frequency range designation FR3 (7.125 GHz - 24.25 GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, and thus can effectively extend the features of FR1 and / or FR2 into the IF band. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating frequency bands have been designated as the frequency range designations FR4A or FR4-1 (52.6 GHz - 71 GHz), FR4 (52.6 GHz - 114.25 GHz), and FR5 (114.25 GHz - 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0060] Considering the examples above, unless otherwise specifically stated, it should be understood that the terms "sub-6GHz," etc. (if used herein), can broadly refer to frequencies that may be less than 6GHz, may be within FR1, or may include intermediate frequency band frequencies. Furthermore, unless otherwise specifically stated, it should be understood that the terms "millimeter wave," etc. (if used herein), can broadly refer to frequencies that may include intermediate frequency band frequencies, may be within FR2, FR4, FR4-a, or FR4-1 and / or FR5, or may be within the EHF band. The frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) are contemplated to be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0061] As mentioned above, Figure 1 This is provided as an example. Other examples may differ from the one provided. Figure 1 The example described.

[0062] Figure 2 This is a diagram illustrating example 200 of communication between base station 110 and UE 120 in wireless network 100 according to this disclosure. Base station 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1).

[0063] At base station 110, transmitting processor 220 can receive data from data source 212 intended for UE 120 (or a set of UEs 120). Transmitting processor 220 can select one or more modulation and coding schemes (MCS) for UE 120, at least in part, based on one or more Channel Quality Indicators (CQIs) received from UE 120. Base station 110 can process (e.g., encode and modulate) the data for UE 120, at least in part, based on the MCS selected for UE 120, and can provide data symbols for UE 120. Transmitting processor 220 can process system information (e.g., for Semi-Static Resource Partition Information (SRPI)) and control information (e.g., CQI requests, permission, and / or upper-layer signaling), and provide overhead symbols and control symbols. Transmitting processor 220 can 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, where applicable, and can provide a set of output symbol streams (e.g., T output symbol streams) to a set of corresponding modems 232 (e.g., T modems), shown as modems 232a to 232t. For example, each output symbol stream can be provided to a modulator component (shown as MOD) of modem 232. Each modem 232 can use its respective modulator component to process its respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 can also use a corresponding modulator component to process (e.g., convert to analog, amplify, filter, and / or up-convert) the output sample stream to obtain a downlink signal. Modems 232a to 232t can transmit a set of downlink signals (e.g., T downlink signals) via a set of corresponding antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0064] At UE 120, a set of antennas 252 (shown as antennas 252a to 252r) can receive downlink signals from base station 110 and / or other base stations 110, and can provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal can be provided to a demodulator component (shown as DEMOD) of modem 254. Each modem 254 can use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain an input sample. Each modem 254 can use the demodulator component to further process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 can obtain the received symbols from modem 254, can perform MIMO detection on the received symbols where applicable, and can provide the detected symbols. The receiver 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 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 Reference Signal Received Power (RSRP) parameters, Received Signal Strength Indicator (RSSI) parameters, Reference Signal Received Quality (RSRQ) parameters, and / or CQI parameters, etc. In some examples, one or more components of UE 120 may be included in housing 284.

[0065] 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.

[0066] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc., or may be included in one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), coplanar antenna element sets, non-coplanar antenna element sets, and / or coupled to one or more transmitting and / or receiving components (such as...) Figure 2 One or more antenna elements (one or more components).

[0067] On the uplink, at UE 120, the transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 can generate reference symbols for one or more reference signals. Symbols from the transmit processor 264 can be pre-encoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some examples, the modem 254 of UE 120 may include a modulator and demodulator. In some examples, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver can be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein.

[0068] At base station 110, uplink signals from UE 120 and / or other UEs can be received by antenna 234, processed by modem 232 (e.g., a demodulator component of modem 232, shown as DEMOD), detected by MIMO detector 236 (where applicable), and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and can communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communication. In some examples, modem 232 of base station 110 may include modulator and demodulator. In some examples, base station 110 includes transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein.

[0069] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2Any other component may perform one or more techniques associated with uplink communication rerouting in the user equipment, 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 can execute or direct, for example Figure 5 The operation of process 500 and / or other processes as described herein. Memory 242 and memory 282 may store data and program code for base station 110 and UE 120, respectively. In some examples, 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, or after compilation, translation, and / or interpretation), may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example... Figure 5 The operation of process 500 and / or other processes as described herein. In some examples, execution instructions may include run instructions, transformation instructions, compilation instructions, and / or interpretation instructions, etc.

[0070] In some aspects, UE 120 may include: components for receiving a first configuration to perform uplink communication using a first spectrum band; components for receiving a second configuration to receive downlink communication using a second spectrum band; components for determining interference caused by at least one spectrum band of the first or second spectrum band; and / or components for rerouting uplink communication to a first or second uplink path associated with the first spectrum band, at least in part based on the determination. In some aspects, these components may include combinations of... Figure 2 One or more components of the described UE 120, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256 and / or receive processor 258.

[0071] As mentioned above, Figure 2 This is provided as an example. Other examples may differ from the one provided. Figure 2 The example described.

[0072] Figure 3 This is a diagram illustrating example 300 of a radio protocol architecture according to this disclosure.

[0073] like Figure 3As shown, a radio protocol architecture for primary cell group (MCG) bearers, secondary cell group (SCG) bearers, and segmented bearers can be defined for the UE in Multi-Radio Dual Connectivity (MR-DC) with Evolved Universal Terrestrial Radio Access-New Radio (E-UTRA-NR) Dual Connectivity (EN-DC). Segmented bearers can be associated with the NR Packet Data Convergence Protocol (PDCP) layer, the E-UTRA Radio Link Control (RLC) layer, and the NR RLC layer. MCG bearers can be associated with the E-UTRA / NR PDCP layer, the E-UTRA RLC layer, and the E-UTRA Medium Access Control (MAC) layer. SCG bearers can be associated with the NR PDCP layer, the NR RLC layer, and the NR MAC layer.

[0074] Paths associated with the E-UTRA RLC layer and / or E-UTRA MAC layer can correspond to LTE paths or E-UTRA paths. Paths associated with the NR RLC layer and / or NR MAC layer can correspond to NR paths.

[0075] As mentioned above, Figure 3 This is provided as an example. Other examples may differ from the one provided. Figure 3 The example described.

[0076] The UE (e.g., UE 120) can operate in a next-generation RAN (NG-RAN), which supports NR-NR dual connectivity (NR-DC), where the UE can connect to one gNB acting as the primary node (MN) and another gNB acting as the secondary node (SN). Alternatively, NR-DC can also be used when the UE connects to two gNB distributed units (gNB-DUs), one serving the MCG and the other the SCG, which can connect to the same gNB central unit (gNB-CU) and can act as both the MN and SN.

[0077] The network can configure a primary uplink path for the UE. When the data volume does not meet the threshold configured by the network, the UE can transmit data on this primary uplink path. The primary uplink path can be an LTE path or an NR path. Both the LTE and NR paths can be uplink signal paths. The LTE path can be referred to as the first uplink path, and the NR path can be referred to as the second uplink path. The LTE path can also be referred to as an E-UTRA path. The threshold configured by the network can be an uplink data splitting threshold (ul-DataSplitThreshold). When the data volume meets the threshold configured by the network, uplink data used for the UE's non-standalone (NSA) uplink splitting bearer can be split between the LTE and NR paths.

[0078] The UE may experience first coexistence, where concurrent uplink communication between the LTE and NR paths can lead to sensitivity degradation in downlink reception at the UE for band combinations with intermodulation distortion. NR power backoff can be applied to the NR path to reduce sensitivity degradation for band combinations with intermodulation distortion. In other words, power backoff can reduce or weaken output power, thereby reducing sensitivity degradation. NR power backoff can occur during voice calls (e.g., LTE path experiencing sensitivity degradation) when the LTE path is the victim. In this case, the LTE path can be used for uplink communication. For other types of traffic (e.g., traffic without power backoff but to be protected from sensitivity degradation), uplink communication can be performed on one link at a time, such as on either the LTE or NR path, but not simultaneously on both.

[0079] The UE may experience a second coexistence, in which the millimeter-wave intermediate frequency (mmW IF) or sub-6 GHz high-frequency band used by the UE may conflict with the ultra-wideband (UWB) radar frequency used by the UE. The mmW IF or sub-6 GHz band used by the UE may be associated with the UE's cellular radio access technology (RAT). The mmW IF or sub-6 GHz high-frequency band used by the UE may be associated with LTE and / or NR paths. The UWB radar frequency used by the UE may be associated with the UE's radar RAT. The UWB radar frequency may be in the 5-10 GHz range. When the mmW IF or sub-6 GHz high-frequency band conflicts with the UWB radar frequency, uplink communication routed on the NR path can be moved to the LTE path to reduce sensitivity degradation to the UWB radar frequency. When the LTE path is associated with the mmW IF or sub-6 GHz high-frequency band, the LTE path can be considered an attacker (e.g., the LTE path causes sensitivity degradation to the UWB radar frequency), and uplink communication initially routed on the LTE path can be moved to the NR path.

[0080] The UE can be configured to perform uplink communication on both LTE and NR paths, at least in part, based on its uplink segmented bearer. However, when uplink communication occurs simultaneously on both LTE and NR paths, the UE may experience a first coexistence, which could lead to a degradation in downlink reception sensitivity at the UE. Furthermore, the UE can be configured to operate using multiple RATs, including a cellular RAT and a radar RAT. When the frequency associated with the cellular RAT (e.g., mmW IF or sub-6 GHz high-frequency band frequencies) conflicts with the frequency associated with the radar RAT (e.g., UWB radar frequencies), the UE may experience a second coexistence, thereby degrading its performance.

[0081] In various aspects of the techniques and apparatus described herein, uplink communication associated with an application executing on a UE can be rerouted to an LTE path or an NR path. In some aspects, the UE can reroute uplink communication on an LTE or NR path based at least in part on which path (LTE or NR) is the attacker regarding a radar RAT. In some aspects, the UE can reroute uplink communication on an LTE or NR path based at least in part on whether power backoff is enabled or disabled for the NR path. In some aspects, the UE can reroute uplink communication on an LTE or NR path based at least in part on a higher estimated link throughput and / or measured throughput. In some aspects, the UE can reroute uplink communication on an LTE or NR path based at least in part on a Buffer State Report (BSR) adjustment mechanism. In some aspects, the UE can reroute uplink communication on an LTE or NR path based at least in part on criteria received from the client application.

[0082] Figure 4 This is a diagram illustrating uplink communication rerouting in the UE according to this disclosure. (See diagram for example.) Figure 4 As shown, Example 400 includes communication between a UE (e.g., UE 120) and a base station (e.g., base station 110). In some aspects, the UE and the base station may be included in a wireless network such as wireless network 100. The UE and the base station may communicate on a wireless sidelink.

[0083] As shown by reference numeral 402 in the attached figure, the UE can receive a first configuration to perform uplink communication using a first spectrum band. The uplink communication can be associated with an application running on the UE. The UE can also receive a second configuration to receive downlink communication using a second spectrum band.

[0084] In some aspects, the first spectrum band may be associated with a high-frequency band of mmW IF or sub-6 GHz, and the second spectrum band may be associated with a UWB radar frequency. In some aspects, the first spectrum band may be associated with a cellular RAT, and the second spectrum band may be associated with a radar RAT.

[0085] As shown by reference numeral 404 in the attached figure, the UE can determine interference caused by at least one of a first spectrum band or a second spectrum band. In some aspects, the UE can determine, at least in part, that the interference causes a degradation in sensitivity for downlink reception at the UE based on a first uplink communication associated with an LTE path occurring concurrently with a second uplink communication associated with an NR path. The LTE path and the NR path can be associated with the first spectrum band. The LTE path and the NR path can be associated with the UE's uplink segmented bearer. The UE can determine interference for one or more frequency band combinations with intermodulation distortion.

[0086] In some aspects, the UE may determine interference based at least in part on the conflict between a first spectral band (e.g., mmWIF or sub-6GHz high-frequency band) associated with the cellular RAT and a second spectral band (e.g., UWB radar band) associated with the radar RAT.

[0087] In some aspects, interference can be associated with a first coexistence between LTE and NR paths associated with a cellular RAT, where the LTE and NR paths are associated with the UE's uplink segmented bearer. The UE can detect this first coexistence when a first uplink transmission associated with the first uplink path and a second uplink transmission associated with the second uplink path occur concurrently for one or more frequency band combinations with intermodulation distortion, resulting in a degraded sensitivity of downlink reception at the UE. In some aspects, interference can be associated with a second coexistence between the UE's cellular RAT and radar RAT. The UE can detect this second coexistence when a conflict occurs between a mmW IF or sub-6GHz high-frequency band associated with the cellular RAT and a UWB radar frequency associated with the radar RAT.

[0088] As shown by reference numeral 406 in the attached figure, the UE may reroute uplink communication associated with an application running on the UE to an LTE path or an NR path based at least in part on the occurrence of interference. In some aspects, the UE may route uplink communication on an LTE path or an NR path based at least in part on which of the LTE or NR paths is the attacker regarding radar RAT. In some aspects, the UE may route uplink communication on an LTE path or an NR path based at least in part on whether power backoff is enabled or disabled for the NR path. In some aspects, the UE may route uplink communication on an LTE path or an NR path based at least in part on a higher estimated link throughput and / or measured throughput. In some aspects, the UE may route uplink communication on an LTE path or an NR path based at least in part on BSR adjustment. In some aspects, the UE may route uplink communication on an LTE path or an NR path based at least in part on criteria received from the client application.

[0089] In some aspects, the UE can reroute uplink communication to the LTE path at least in part based on the determination of interference (e.g., when the LTE path or NR path is an attacker). The primary uplink path can be set to the LTE path, and the uplink data segmentation threshold can be set to a maximum value (e.g., infinity). In some aspects, the UE can reroute uplink communication to the NR path at least in part based on the determination of interference (e.g., when the LTE path or NR path is an attacker). The primary uplink path can be set to the NR path, and the uplink data segmentation threshold can be set to a maximum value. The UE can reroute uplink communication to the LTE path or NR path for one or more coexisting frequency band combinations.

[0090] For example, start and end times can be detected for uplink application data (e.g., uplink data associated with a video call). The UE can reroute uplink application data via its modem on either the LTE or NR path, depending on whether the LTE or NR path is the attacker's. Furthermore, the UE can reroute uplink application data when the uplink data segmentation threshold equals its maximum value (e.g., infinity). As an example, the uplink data segmentation threshold could equal its maximum value during the duration of a video call, causing the uplink application data to be rerouted to either the LTE or NR path.

[0091] In some aspects, power backoff can be enabled for applications and / or secondary uplink paths, and uplink communication can be rerouted to LTE paths to protect the uplink from power backoff associated with NR paths. As an example, when power backoff is enabled for video calls, uplink application data can be rerouted to LTE paths to protect the uplink from NR power backoff and potential errors in video calls. Uplink application data can be rerouted to LTE paths for bearers associated with video call services.

[0092] In some aspects, power backoff can be disabled for applications and / or second uplink paths, and uplink communication can be rerouted to LTE paths to protect the downlink from sensitivity degradation. As an example, when a video call is associated with a segmented bearer, uplink application data transmitted concurrently with downlink data can be rerouted to LTE paths to protect the downlink from sensitivity degradation caused by concurrent uplink application data. Uplink application data can be rerouted to LTE paths for multiple uplink segmented bearers used by the UE.

[0093] In some aspects, LTE or NR paths can carry services, but not simultaneously. In some cases, services can be carried on the LTE path, but the NR path may be a better link than the LTE path, leading to a degradation in uplink performance. Furthermore, some secondary cell group (SCG) bearers can transmit uplink data, such as Radio Link Control (RLC) status information and / or uplink control channel information, on the NR path, which may further contribute to sensitivity degradation.

[0094] In some aspects, when power backoff is enabled for an NR path, the UE can reroute uplink communication to an LTE path for a bearer associated with the application. As an example, NR power backoff can be enabled to protect the uplink for application data. The UE can select an LTE path for the uplink of a segmented bearer associated with application data. Because NR power backoff can be enabled, the LTE path can be used for segmented bearers carrying application data.

[0095] In some aspects, the UE may reroute uplink communication to an LTE or NR path, at least in part, based on one or more bearers associated with the UE, and when power backoff is disabled for the NR path. In some aspects, the UE may reroute uplink communication to an LTE path when one or more bearers include an MCG bearer. In some aspects, the UE may reroute uplink communication to an NR path when one or more bearers include an SCG bearer.

[0096] As an example, NR power backoff can be disabled to protect downlink application data. The UE can select either an LTE or NR path for multiple segmented bearers, at least in part, based on the presence of an additional bearer. For instance, when the UE is associated with an MCG bearer, it can choose an LTE path, thus rerouting uplink application data on the LTE path. When the UE is associated with an SCG bearer, it can choose an NR path, thus rerouting uplink application data on the NR path. When the UE is associated with both an MCG bearer and an SCG bearer, it can continue to route uplink application data to either the LTE or NR path.

[0097] In some aspects, the UE may include segmented bearers, but may not include MCG or SCG bearers. In this case, the UE may determine the rerouting of uplink communication based at least in part on downlink scheduling rates and / or uplink scheduling rates.

[0098] In some aspects, the UE can measure the downlink scheduling rate on one or more links for a segmented bearer associated with an application running on the UE. The downlink scheduling rate can indicate the percentage of time the downlink is scheduled. The UE can measure the uplink scheduling rate on one or more links for multiple segmented bearers associated with the UE. The uplink scheduling rate can indicate the percentage of time the uplink is scheduled. When the downlink scheduling rate associated with the segmented bearer meets a downlink scheduling threshold on the downlink path and the uplink scheduling rate meets an uplink scheduling threshold on the NR path, the UE can reroute uplink communication to the LTE path. Alternatively, when the downlink scheduling rate associated with the segmented bearer meets a downlink scheduling threshold on the downlink path and the uplink scheduling rate meets an uplink scheduling threshold on the LTE path, the UE can reroute uplink communication to the NR path.

[0099] In some aspects, the UE can measure the downlink scheduling rate for segmented bearers on each link carrying application data (e.g., services associated with video calls). The segmented bearer carrying application data can be a default bearer. The UE can measure the uplink scheduling rate for each link of multiple segmented bearers (e.g., all segmented bearers) for the UE. In some aspects, when the LTE path is considered the victim, and the segmented bearer associated with the downlink scheduling rate exceeds a downlink scheduling threshold on LTE and the uplink scheduling rate exceeds an uplink scheduling threshold on NR, the UE can reroute application data to the LTE path. In some aspects, when the NR path is considered the victim, and the segmented bearer associated with the downlink scheduling rate exceeds a downlink scheduling threshold on NR and the uplink scheduling rate exceeds an uplink scheduling threshold on the UE, the UE can reroute application data to the NR path. As an example, the downlink scheduling threshold can be 90% of packets, and the uplink scheduling threshold can be 10% of packets, where the packets can be PDCP packets.

[0100] In some respects, when there is a relatively equal downlink service distribution for LTE and NR, the uplink control channel and RLC acknowledgment can exist on multiple links associated with the segmented bearer of the UE.

[0101] In some respects, the UE may reroute uplink communication to an LTE path or an NR path based at least in part on a higher estimated link throughput. The higher estimated link throughput may include a first value associated with the LTE path and a second value associated with the NR path.

[0102] As an example, a UE may select either the LTE path or the NR path as the primary uplink path based at least in part on a higher estimated link throughput. A higher estimated link throughput provides the expected throughput supported on the link associated with the UE's segmented bearer. The higher estimated link throughput may be determined at least in part based on network scheduling. As an example, a higher estimated link throughput may be selected at the start of a video call, and when application data associated with the video call switches from a first uplink path to a second uplink path (e.g., from an LTE path to an NR path, or vice versa), the UE may be unable to determine an accurate estimate for the first uplink path due to the lack of network scheduling.

[0103] In some aspects, the UE can reroute uplink communication to an LTE path at least partially based on a higher estimated link throughput. At a later time, the UE can detect that the higher estimated link throughput of the LTE path does not meet a threshold. The UE can then switch uplink communication from the LTE path to an NR path. In other words, when the current uplink path is associated with a higher estimated link throughput that does not meet a threshold, the UE can blindly switch to another uplink path (e.g., from an LTE path to an NR path, and vice versa).

[0104] In some aspects, for the initial portion of a Radio Resource Control (RRC) connection that has not yet started during its scheduling period, the UE may not accurately measure higher estimated link throughput. In this case, the UE may default to rerouting uplink communication to the LTE path.

[0105] In some respects, the UE may reroute uplink communication to the LTE or NR path based at least in part on the measured throughput associated with the LTE and NR paths and / or the block error rate associated with one of the physical or RLC layers.

[0106] In some aspects, the UE can at least partially rely on BSR adjustments to alternately reroute uplink communications on LTE and NR paths, where BSR adjustments allow either the LTE or NR path to be used at a given time. In some cases, in addition to BSR adjustments, RLC status reports can also be adjusted. BSR adjustments can involve the UE reporting a reduced BSR to the base station, which can allow the UE to control the uplink duty cycle and reduce uplink throughput. The UE can adjust the BSR to allow alternating rerouting of uplink communications on LTE and NR paths to avoid concurrent uplink transmissions on both links (e.g., concurrent uplink transmissions on both the UE and NR paths), which can prevent degradation in downlink reception sensitivity at the UE.

[0107] In some respects, the UE can reroute uplink communication to the LTE or NR path based at least in part on BSR adjustments to the LTE or NR path that cause interference. For example, the UE can perform BSR adjustments on the attacker's link associated with the LTE or NR path, which can reduce the sensitivity degradation of the victim (e.g., a second spectrum band associated with a radar RAT that has undergone sensitivity degradation).

[0108] In some aspects, the UE can reroute uplink communication to an LTE or NR path based at least in part on uplink path preference information, interference indication, and / or victim frequency information. The uplink path preference information, interference indication, and / or victim frequency information can be received from a client application or a client. The uplink path preference information may include a preferred uplink path (e.g., an LTE path or an NR path). The interference indication may indicate whether the UE experiences a first coexistence when uplink communication occurs simultaneously on both LTE and NR paths, and / or a second coexistence when a frequency associated with a cellular RAT (e.g., mmW IF or sub-6 GHz high-frequency band) conflicts with a frequency associated with a radar RAT (e.g., UWB radar frequency). The victim frequency information may indicate frequencies experiencing sensitivity degradation in radar, and the UE can calculate the attacker frequency and move uplink communication to an LTE or NR path accordingly.

[0109] As shown by reference numeral 408 in the attached figure, the UE can perform uplink communication with the base station. Uplink communication can be associated with uplink application data (e.g., video call services). For example, uplink application data can be rerouted to the UE's LTE or NR path, and uplink application data can be sent from the UE to the base station.

[0110] As mentioned above, Figure 4This is provided as an example. Other examples may differ from the one provided. Figure 4 The example described.

[0111] Figure 5 This is a diagram illustrating an example process 500 performed by a UE according to this disclosure. Example process 500 is an example in which a UE (e.g., UE 120) performs operations associated with techniques for rerouting uplink communications in the UE.

[0112] like Figure 5 As shown, in some aspects, process 500 may include: receiving a first configuration to perform uplink communication using a first spectrum (block 510). For example, the UE (e.g., using...) Figure 6 The configuration component 608 described herein can receive a first configuration as described above to perform uplink communication using a first spectrum band.

[0113] like Figure 5 As further shown, in some aspects, process 500 may include: receiving a second configuration to use a second spectrum to receive downlink communication (block 520). For example, the UE (e.g., using...) Figure 6 The configuration component 608 described herein can receive a second configuration as described above to receive downlink communication using a second spectrum.

[0114] like Figure 5 As further shown, in some aspects, process 500 may include: determining interference caused by at least one of a first spectral band or a second spectral band (block 530). For example, the UE (e.g., using...) Figure 6 The determining component 610 described herein can determine interference caused by at least one of the first or second spectral bands as described above.

[0115] like Figure 5 As further shown, in some aspects, process 500 may include: at least in part based on this determination, rerouting uplink communication to a first uplink path or a second uplink path associated with the first spectrum band (box 540). For example, the UE (e.g., using...) Figure 6 The rerouting component 612 described herein can, at least in part, reroute uplink communication to a first uplink path or a second uplink path associated with the first spectrum band, based on this determination, as described above.

[0116] Process 500 may include additional aspects, such as any single aspect or any combination of aspects of one or more other processes described below and / or in conjunction with those described elsewhere in this document.

[0117] In the first aspect, the first uplink path and the second uplink path are associated with the uplink segmented bearer of the UE.

[0118] In the second aspect, either alone or in combination with the first aspect, the first uplink path is an E-UTRA path, and the second uplink path is an NR path.

[0119] In a third aspect, either alone or in combination with one or more of the first and second aspects, process 500 includes: a first spectral band associated with a millimeter-wave intermediate frequency or a sub-6 GHz frequency, and a second spectral band associated with an ultra-wideband radar frequency.

[0120] In a fourth aspect, either alone or in combination with one or more of the first to third aspects, process 600 includes: a first spectral band associated with a cellular RAT, and a second spectral band associated with a radar RAT.

[0121] In a fifth aspect, either alone or in combination with one or more of the first to fourth aspects, determining the interference includes: for one or more frequency band combinations having intermodulation distortion, determining that second uplink communication associated with the second uplink path concurrently occurring with first uplink communication associated with the first uplink path causes a degradation in the sensitivity of downlink reception at the UE.

[0122] In the sixth aspect, either alone or in combination with one or more of the first to fifth aspects, determining the interference includes: identifying a conflict between a millimeter-wave intermediate frequency or sub-6 GHz frequency associated with a cellular RAT and an ultra-wideband radar frequency associated with a radar RAT.

[0123] In the seventh aspect, alone or in combination with one or more of the first to sixth aspects, rerouting uplink communication includes: for one or more coexisting frequency band combinations, rerouting uplink communication to a first uplink path based at least in part on the determination of interference, wherein the primary uplink path is set as the first uplink path and the uplink data segmentation threshold is set to a maximum value.

[0124] In the eighth aspect, either alone or in combination with one or more of the first to seventh aspects, rerouting uplink communication includes: for one or more coexisting frequency band combinations, rerouting uplink communication to a second uplink path based at least in part on the determination of interference, wherein the primary uplink path is set as the second uplink path, and the uplink data segmentation threshold is set to a maximum value.

[0125] In the ninth aspect, either alone or in combination with one or more of the first to eighth aspects, power backoff is enabled for the second uplink path, and uplink communication is rerouted to the first uplink path to protect the uplink from the power backoff associated with the second uplink path.
