[0001] This application claims priority and benefit of U.S. Non-Provisional Patent Application No. 16 / 804,581, filed February 28, 2020, and Indian Provisional Patent Application No. 201941012460, filed March 29, 2019, the entire contents of which are incorporated herein by reference in their entirety as if fully presented hereafter and for all applicable purposes. TECHNICAL FIELD

[0002] This application relates to wireless communication systems and, more particularly, to the sharing of a channel occupation time (COT) associated with a scheduled UL transmission in a frequency spectrum shared by multiple network operating entities. INTRODUCTION

[0003] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing available system resources (such as time, frequency, and power). A wireless multiple access communication system may include a number of base stations (BSs), each simultaneously supporting communications to multiple users. Petition 870250088930, dated 10 / 01 / 2025, page 49 / 237 2 / 79 communication devices, which may otherwise be known as user equipment (UE).

[0004] To meet the growing demands for expanded mobile broadband connectivity, wireless communication technologies are advancing from Long Term Evolution (LTE) technology to next-generation New Radio (NR) technology. For example, NR is designed to provide lower latency, higher bandwidth or higher throughput, and higher reliability than LTE. NR is designed to operate across a wide range of spectrum bands, for example, from low-frequency bands below about 1 gigahertz (GHz) and mid-frequency bands from about 1 GHz to about 6 GHz, up to high-frequency bands such as millimeter wave (mmWave) bands. NR is also designed to operate across different types of spectrum, from licensed spectrum to unlicensed and shared spectrum.Spectrum sharing allows operators to opportunistically aggregate spectrum to dynamically support higher-bandwidth broadband services. Spectrum sharing can extend the benefits of NR technologies to operating entities that may not have access to licensed spectrum.

[0005] One approach to avoid collisions when communicating on a shared spectrum or an unlicensed spectrum is to use a listen-before-talk (LBT) procedure to ensure that the shared channel is free before Petition 870250088930, dated 10 / 01 / 2025, p. 50 / 237 3 / 79 transmit a signal on the shared channel. NR operations or deployments in an unlicensed spectrum are referred to as NR-U. In NR-U, a transmit node (such as a BS or UE) may perform a Category 1 (CAT1) LBT (such as no LBT measurement), a Category 2 (CAT2) LBT, or a Category 4 (CAT4) LBT before transmitting a communication signal in an unlicensed frequency band. For example, a BS may acquire a COT in an unlicensed frequency band by performing a CAT4 LBT. The BS may schedule one or more UEs for UL and / or DL ​​communication within the BS's COT. Additionally, the BS may schedule one or more UEs for UL communication outside the BS's COT. A UE with a UL schedule within the BS's COT may perform a CAT2 LBT before the scheduled UL transmission. A UE with a scheduled UL outside the BS COT can perform a CAT4 LBT prior to the scheduled UL transmission. A brief summary of some examples.

[0006] Next, a simplified summary of some aspects of the present disclosure is presented to provide a basic understanding of the technology discussed. This summary is not an extensive overview of all contemplated aspects of the disclosure, and it does not purport to identify key or essential elements of all aspects of the disclosure, nor to delineate the scope of any or all aspects of the disclosure.

[0023] The detailed description presented below, in connection with the attached drawings, is intended to be a description of various configurations and is not intended to represent the only configurations in which the concepts described herein can be practiced. The detailed description Petition 870250088930, dated 10 / 01 / 2025, page 55 / 237 8 / 79 includes specific details for the purpose of providing a complete understanding of the various concepts. However, it will be evident to those skilled in the art that these concepts can be practiced without these specific details. In some examples, well-known structures and components are shown in block diagram form in order to avoid obscuring these concepts.

[0024] This disclosure generally refers to wireless communication systems, also referred to as wireless communication networks. In various embodiments, techniques and devices may be used for wireless communication networks, such as code division multiple access (CDMA) networks, time division multiple access (TDMA) networks, frequency division multiple access (FDMA) networks, orthogonal FDMA (OFDMA) networks, single carrier FDMA (SC-FDMA) networks, LTE networks, Global System for Mobile Communications (GSM) networks, 5th Generation (5G) networks or new radio (NR) networks, as well as other communication networks. As described herein, the terms networks and systems may be used interchangeably.

[0025] An OFDMA network can implement a radio technology, such as Evolved UTRA (E-UTRA), Institute of Electrical and Electronics Engineers (IEEE) 802.11, IEEE 802.16, IEEE 802.20, Flash-OFDM, and similar technologies. UTRA, E-UTRA, and GSM are part of the Universal Mobile Telecommunications System (UMTS). In particular, Long Term Evolution (LTE) is a version of UMTS that uses E-UTRA. UTRA, E-UTRA, GSM, UMTS, and LTE are described in documents provided by a Petition 870250088930, dated 10 / 01 / 2025, page 56 / 237 9 / 79 organization called “3rd Generation Partnership Project” (3GPP), and cdma2000 is described in documents from an organization called “3rd Generation Partnership Project 2” (3GPP2). These various radio technologies and standards are known or are being developed. For example, the 3rd Generation Partnership Project is a collaboration between groups of telecommunications associations that aims to define a globally applicable third-generation (3G) mobile phone specification. The long-term evolution of 3GPP (LTE) is a 3GPP project that aimed to improve the UMTS mobile telephony standard. 3GPP may define specifications for the next generation of mobile networks, mobile systems, and mobile devices. The present disclosure relates to the evolution of wireless technologies from LTE, 4G, 5G, NR and beyond, with shared access to the wireless spectrum between networks that utilize a combination of new and different radio access technologies or radio air interfaces.

[0026] In particular, 5G networks encompass diverse deployments, diverse spectrums, and diverse services and devices that can be implemented using a unified air interface based on OFDM. In order to achieve these goals, further enhancements to LTE and LTE-A are considered, in addition to the development of New Radio technology for NR 5G networks. NR 5G will be able to scale to provide coverage (1) for a massive Internet of Things (IoTs) with ultra-high density (e.g., ~1M nodes / km2), ultra-low complexity (e.g., ~10s of bits / s), ultra-low power (e.g., ~10+ Petition 870250088930, dated 10 / 01 / 2025, page 57 / 237 (1) 10 / 79 years of battery life) and deep coverage with the ability to reach challenging locations; (2) include mission-critical control with strong security to safeguard confidential personal, financial, or classified information, ultra-high reliability (e.g., ~99.9999% reliability), ultra-low latency (e.g., ~1 msec), and users with wide ranges of mobility or lack thereof; and (3) with enhanced mobile broadband, which includes extremely high capacity (e.g., ~10 Tbps / km2), extreme data rates (e.g., multi-Gbps rates, +100 Mbps user experience rates), and deep insights with advanced discoveries and optimizations.

[0027] NR 5G can be implemented to utilize OFDM-based waveforms optimized with scalable numerology and transmission time interval (TTI); having a common and flexible framework to efficiently multiplex services and resources with a dynamic, low-latency time-division duplex (TDD) / frequency-division duplex (FDD) design; and with advanced wireless technologies such as massively multi-input multiple-output (MIMO), robust millimeter-wave (mmWave) transmissions, advanced channel coding, and device-centric mobility. The scalability of numerology in NR 5G, with subcarrier spacing scaling, can efficiently handle the operation of diverse services across diverse spectrums and deployments. For example, in various outdoor and macro-coverage deployments, of Petition 870250088930, dated 10 / 01 / 2025, page 58 / 237 For FDD / TDD implementations below 3 GHz, subcarrier spacing can occur at 15 kHz, for example, over 5, 10, 20 MHz and similar bandwidths (BW). For various other outdoor coverage and small cell TDD deployments greater than 3 GHz, subcarrier spacing can occur at 30 kHz over 80 / 100 MHz BW. For various other indoor broadband implementations, which utilize a TDD over the unlicensed portion of the 5 GHz band, subcarrier spacing can occur at 60 kHz over 160 MHz BW. Finally, for various deployments that transmit with mmWave components on a 28 GHz TDD, subcarrier spacing can occur at 120 kHz over 500 MHz BW.

[0028] NR 5G's scalable numerology facilitates scalable TTI for various latency and quality of service (QoS) requirements. For example, shorter TTI can be used for low latency and high reliability, while longer TTI can be used for greater spectral efficiency. Efficient multiplexing of long and short TTIs allows transmissions to start at symbol boundaries. NR 5G also features an integrated autonomous subframe design with uplink / downlink scheduling information, data, and acknowledgment in the same subframe. The integrated autonomous subframe supports communications in unlicensed shared spectrum or contention-based, adaptive uplink / downlink that can be flexibly configured on a per-cell basis to dynamically switch between uplink and downlink to meet current traffic needs.

[0029] Several other aspects and features of the revelation are further described below. It should be evident that the teachings herein can be incorporated in a wide variety of ways and that any specific structure, function, or both being revealed herein are merely representative and not limiting. Based on the teachings presented herein, anyone at the level of those versed in the technique should recognize that an aspect revealed herein can be implemented independently of any other aspects and that two or more of these aspects can be combined in various ways. For example, a device can be implemented or a method can be practiced using any of the aspects set forth herein. Furthermore, such a device can be implemented or such a method can be practiced using another structure, functionality, or structure and functionality in addition to or different from one or more of the aspects set forth herein.For example, a method may be implemented as part of a system, device, apparatus, and / or as instructions stored in a computer-readable medium for execution on a processor or computer. Furthermore, an aspect may comprise at least one element of a claim.

[0030] This application describes mechanisms for sharing a COT associated with a scheduled UL transmission in a frequency spectrum shared by multiple network operating entities. For example, a base station (BS) transmits a UL scheduling grant that grants an UE with a UL schedule outside of a BS COT. Upon receiving the grant of Petition 870250088930, dated 10 / 01 / 2025, page 60 / 237 13 / 79 UL scheduling, the UE performs a CAT4 LBT before scheduling the UL. After passing the LBT, the UE obtains a COT and transmits a UL communication signal according to the schedule.

[0031] In one embodiment, the UE may include COT sharing information in the UL communication signal to enable the BS to share the UE's COT for DL ​​communications. The COT sharing information may indicate a start time and / or a duration of a portion of the UE's COT that is shareable by the BS. The BS may transmit a DL communication to the UE during the shareable portion.

[0032] In one embodiment, the BS can indicate a traffic priority class for UL scheduling. The UE can select a different traffic priority class for UL scheduling, transmit data of the selected traffic priority to the BS, and indicate the traffic priority used for UL transmission in the UL communication signal. In one embodiment, the UE can perform multiple hypotheses associated with channel access and packet generation for UL transmission.

[0033] In one embodiment, BS may determine COT sharing information based on UL scheduling grant and / or detection of a UL communication signal based on UL scheduling grant.

[0034] Figure 1 shows a 100 wireless communication network according to some embodiments of the present disclosure. The 100 network may be a 5G network. A Petition 870250088930, dated 10 / 01 / 2025, p. 61 / 237 The 14 / 79 network includes a number of base stations (BSs) 105 (individually labeled as 105a, 105b, 105c, 105d, 105e and 105f) and other network entities. A BS 105 can be a station that communicates with UEs 115 and can also be referred to as an evolved B node (eNB), a next-generation eNB (gNB), an access point, and the like. Each BS 105 can provide communication coverage for a specific geographic area. In 3GPP, the term cell can refer to this specific geographic coverage area of ​​a BS 105 and / or a BS subsystem that serves the coverage area, depending on the context in which the term is used.

[0035] BS 105 can provide communication coverage for a macro cell or a small cell, such as a pico cell or a femto cell and / or other cell types. A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and can allow unrestricted access by UEs with service subscriptions with the network provider. A small cell, such as a pico cell, generally covers a relatively smaller geographic area and can allow unrestricted access by UEs with service subscriptions with the network provider. A small cell, such as a femto cell, also generally covers a relatively small geographic area (e.g., a private residence) and, in addition to unrestricted access, can also provide restricted access by UEs that have an association with the femto cell (e.g., UEs in a closed subscriber group (CSG), UEs for home users, and the like). A BS for a Petition 870250088930, dated 10 / 01 / 2025, p. 62 / 237 A 15 / 79 macro cell can be referred to as a macro BS. A BS for a small cell can be referred to as a small-cell BS, a pico BS, a femto BS, or a native BS. In the example shown in Figure 1, BSs 105d and 105e can be regular macro BSs, while BSs 105a-105c can be macro BSs enabled with one of: three-dimensional (3D), full-dimensional (FD), or massive MIMO. BSs 105a-105c can take advantage of their full-dimensional MIMO capabilities, but elevated to exploit 3D beamforming in both elevation and azimuth beamforming to increase coverage and capacity. BS 105f can be a small-cell BS that can be a native node or a portable access point. A BS 105 can support one or multiple (such as two, three, four, and similar) cells.

[0036] Network 100 can support synchronous or asynchronous operation. For synchronous operation, BSs can have similar frame timing and transmissions from different BSs can be approximately time-aligned. For asynchronous operation, BSs can have different frame timing and transmissions from different BSs can be time-out.

[0037] UEs 115 are dispersed throughout the wireless network 100, and each UE 115 can be stationary or mobile. A UE 115 may also be referred to as a terminal, a mobile station, a subscriber unit, a station, or similar. A UE 115 can be a mobile phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a device Petition 870250088930, dated 10 / 01 / 2025, page 63 / 237 A UE115 can be a device that includes a Universal Integrated Circuit Card (UICC). In some respects, UE115s that do not include a UICC may also be referred to as IoT devices or Internet of Everything (IoE) devices. UE115s a-115d are examples of mobile smartphone-type devices that access the 100 network. A UE115 can also be a machine specifically configured for connected communication, which includes mechanical-type communication (MTC), enhanced MTC (eMTC), narrowband IoT (NB-IoT), and similar devices. UEs 115e-115h are examples of various machines configured for communication that access the 100 network. A UE 115 may be able to communicate with any type of BSs, whether macro BS, small cell, or similar. In Figure 1, the lightning bolt representation (as, for example, communication links) indicates wireless transmissions between a UE 115 and a service BS 105, which is a BS designated to serve the UE 115 in the downlink and / or uplink, or desired transmission between BSs and return transport transmissions between BSs.

[0038] When operational, BSs 105a-105c can serve UEs 115a and 115b using 3D beamforming and coordinated spatial techniques, such as coordinated multipoint (CoMP) or multiple connectivity. Macro BS 105d can perform return transport communications with BSs 105a-105c, as well as BS 105f with Petition 870250088930, dated 10 / 01 / 2025, page 64 / 237 17 / 79 small cells. The BS 105d macro can also transmit multicast services that are subscribed to and received by the UEs 115c and 115d. Such multicast services may include mobile television or streaming video, or may include other services to provide community information, such as emergencies, weather alerts, AMBER alerts, or Gray alerts.

[0039] BSs 105 can also communicate with a core network. The core network can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. At least some of the BSs 105 (such as, for example, a gNB or an access node controller (ANC)) can interface with the core network via return transport links (such as, for example, NG-C, NG-U, etc.) and can perform radio configuration and scheduling for communication with the UEs 115. In several instances, the BSs 105 can communicate, either directly or indirectly (such as, for example, via the core network), with each other via return transport links (such as, for example, X1, X2, etc.), which can be wired or wireless communication links.The 100 network can also support mission-critical communications with ultra-reliable and redundant links to mission-critical devices, such as the UE 115e, which can be a drone. Redundant communication links with the UE 115e can include links from the macro BS 105d and 105e, as well as links from the small-cell BS 105f. Other mechanical-type devices, such as the UE 115f (for example, a...) Petition 870250088930, dated 10 / 01 / 2025, page 65 / 237 18 / 79 thermometer), the UE 115g (such as a smart meter) and the UE 115h (such as a wearable device), can communicate via the 100 network or directly with BSs, such as the small-cell BS 105f and the macro BS 105e, or in multi-hop configurations, communicating with another user device that relays its information to the network, such as the UE 115f communicating temperature measurement information to the smart meter, the UE 115g, which is then reported to the network via the small-cell BS 105f. The 100 network can also provide additional network efficiency through dynamic low-latency TDD / FDD communications, such as vehicle-to-vehicle (V2V), vehicle-to-everything (V2X), vehicle-to-cellular-to-everything (C-V2X) communications between an UE 115i, 115j, or 115k and other UE 115s, and / or vehicle-to-infrastructure (V2I) communications between an UE 115i, 115j, or 115k and a BS 105.

[0040] In some implementations, the 100 network uses OFDM-based waveforms for communications. An OFDM-based system can partition the BW system into multiple orthogonal subcarriers (K), which are also commonly referred to as subcarriers, tones, binaries, or similar. Each subcarrier can be modulated with data. In some examples, the subcarrier spacing between adjacent subcarriers can be fixed, and the total number of subcarriers (K) can be dependent on the BW system. The BW system can also be partitioned into sub-bands. In other examples, the subcarrier spacing and / or the duration of the TTIs can be scalable. Petition 870250088930, dated 10 / 01 / 2025, p. 66 / 237 19 / 79

[0041] In one embodiment, BSs 105 can assign or schedule transmission resources (for example, in the form of time-frequency (RB) resource blocks) for downlink (DL) and uplink (UL) transmissions on the 100 network. DL refers to the transmission direction from a BS 105 to a UE 115, while UL refers to the transmission direction from a UE 115 to a BS 105. Communication can be in the form of radio frames. A radio frame can be divided into a plurality of subframes or partitions, for example, into about 10. Each partition can be further divided into mini-partitions. In an FDD mode, simultaneous UL and DL transmissions can occur in different frequency bands. For example, each subframe includes a UL subframe in a UL frequency band and a DL subframe in a DL frequency band. In TDD mode, UL and DL transmissions occur at different times using the same frequency band.For example, a subset of subframes (such as DL subframes) in a radio frame can be used for DL ​​transmissions, and another subset of subframes (such as UL subframes) in the radio frame can be used for UL transmissions.

[0042] DL and UL subframes can be divided into several regions. For example, each DL or UL subframe can have predefined regions for reference signal transmissions, control information, and data. Reference signals are predetermined signals that facilitate communication between BSs 105 and UEs 115. For example, a reference signal may have a particular pilot pattern or structure, where the tones Petition 870250088930, dated 10 / 01 / 2025, p. 67 / 237 20 / 79 pilots can cover an operational BW or frequency band, each positioned at a predefined time and frequency. For example, a BS 105 can transmit cell-specific reference signals (CRSs), channel state information reference signals (CSI-RSs), and / or demodulation reference signals (DMRSs) to allow a UE 115 to estimate a DL channel. Similarly, a UE 115 can transmit probe reference signals (SRSs) and / or DMRSs to allow a BS 105 to estimate a UL channel. Control information may include resource assignments and protocol controls. Data may include protocol data and / or operational data. In some modes, BS 105s and UE 115s can communicate using autonomous subframes. An autonomous subframe can include a portion for DL ​​communication and a portion for UL communication. An autonomous subframe can be DL-centric or UL-centric. A DL-centric subframe can include a longer duration for DL ​​communication than for UL communication. A UL-centric subframe can include a longer duration for UL communication than for UL communication.

[0043] In one embodiment, the 100 network may be an NR network deployed over a licensed spectrum. BSs 105 can transmit synchronization signals (such as, for example, those that include a primary synchronization signal (PSS) and a secondary synchronization signal (SSS)) on the 100 network to facilitate synchronization. BSs 105 can broadcast system information associated with the 100 network (such as, for example, those that include a MIB, Petition 870250088930, dated 10 / 01 / 2025, page 68 / 237 21 / 79 Minimum Remaining System Information (RMSI) and Other System Information (OSI) to facilitate initial network access. In some examples, BSs 105 can broadcast the PSS, SSS, and / or MIB in the form of synchronization signal blocks (SSBs) through a physical broadcast channel (PBCH) and can broadcast the RMSI and / or OSI through a shared physical downlink channel (PDSCH).

[0044] In one embodiment, a UE 115 attempting to access the 100 network can perform an initial cell search, detecting a PSS from a BS 105. The PSS may allow period timing synchronization and may indicate a physical layer identity value. The UE 115 can then receive an SSS. The SSS may allow radio frame synchronization and may provide a cell identity value, which can be combined with the physical layer identity value to identify the cell. The PSS and SSS can be located in a central part of a carrier wave or at any suitable frequencies within the carrier wave.

[0045] After receiving the PSS and the SSS, the EU UE115 can receive a MIB. The MIB may include system information for initial network access and scheduling information for RMSI and / or OSI. After decoding the MIB, UE115 can receive RMSI and / or OSI. The RMSI and / or OSI may include radio resource control (RRC) information related to random access channel procedures (RACH), paging, resource control set (CORESET) for monitoring physical downlink control channel (PDCCH), and physical uplink control channel. Petition 870250088930, dated 10 / 01 / 2025, page 69 / 237 22 / 79 (PUCCH), shared physical uplink channel (PUSCH), power control and SRS.

[0046] After obtaining the MIB, RMSI, and / or OSI, UE 115 can perform a random access procedure to establish a connection with BS 105. For the random access procedure, UE 115 can transmit a random access preamble, and BS 105 can respond with a random access response. After receiving the random access response, UE 115 can transmit a connection request to BS 105, and BS 105 can respond with a connection response (such as a contention resolution message).

[0047] After establishing a connection, the UE 115 and the BS 105 can enter a normal operating stage where operational data can be exchanged. For example, the BS 105 can schedule the UE 115 for UL and / or DL ​​communications. The BS 105 can transmit UL and / or DL ​​scheduling grants to the UE 115 via a PDCCH. The BS 105 can transmit a DL communication signal to the UE 115 via a PDSCH according to a DL scheduling grant. The UE 115 can transmit a UL communication signal to the BS 105 via a PUSCH and / or PUCCH according to a UL scheduling grant.

[0048] In one embodiment, the 100 network can operate through a BW system or a BW component carrier (CC). The 100 network can partition the BW system into multiple BWPs (such as parts). A BS 105 can dynamically assign a UE 115 to operate through a specific BWP (such as a Petition 870250088930, dated 10 / 01 / 2025, p. 70 / 237 23 / 79 (a specific part of the BW system). The assigned BWP can be referred to as the active BWP. The UE 115 can monitor the active BWP to signal information from the BS 105. The BS 105 can schedule the UE 115 for UL or DL ​​communications on the active BWP. In some modes, a BS 105 can assign a pair of BWPs within the CC to a UE 115 for UL and DL communications. For example, the BWP pair might include one BWP for UL communications and one BWP for DL ​​communications.

[0049] In one embodiment, the 100 network may operate on a shared channel, which may include shared frequency bands or unlicensed frequency bands. For example, the 100 network may be an NR-U network. In such an embodiment, the BSs 105 and UEs 115 may be operated by multiple network operating entities. To avoid collisions, the BSs 105 and UEs 115 may use a listen-before-talk (LBT) procedure to monitor transmission opportunities (TXOPs) on the shared channel. For example, a BS 105 may acquire or reserve a TXOP or a channel occupation time (COT) on the shared channel by performing a CAT4 LBT. A CAT4 LBT refers to an LBT with random offset and a variable contention window. After passing through the LBT, BS 105 can schedule one or more UEs 115 for DL ​​communications and / or UL communications within the purchased COT, as described in more detail here.An LBT can also be referred to as a channel clearance assessment (CCA), where power detection and / or signal detection can be used to determine if a channel is idle or busy. A CAT4 LBT can be referred to as an assessment. Petition 870250088930, dated 10 / 01 / 2025, p. 71 / 237 24 / 79 for extended channel release (eCCA), where recoil mechanisms can be used with CCA.

[0050] Figure 2 is a timing diagram showing a 200 communication scheme according to some embodiments of the present disclosure. The 200 scheme can be used by BSs, such as BSs 105, and UEs, such as UEs 115, in a network, such as network 100. In particular, a BS can use the 200 scheme to schedule a UE for UL communications in a frequency spectrum (such as, for example, an unlicensed spectrum or a shared spectrum) shared by multiple network operating entities. In Figure 2, the geometric x-axis represents time in some arbitrary units.

[0051] In scheme 200, a BS (such as BS 105 in Figure 1) competes for a COT 202 by performing a CAT4 LBT 210 on a shared channel. After passing through the CAT4 LBT 210, COT 202 can begin. The BS can schedule the UE for UL and / or DL ​​communications during COT 202. As shown, the BS transmits a UL scheduling grant 212 to schedule the UE for UL communication at a time T0 within COT 202. The scheduling grant 212 can indicate resources (such as time-frequency resources) allocated for UL communication and / or transmission parameters for UL communication. After receiving the UL scheduling grant 212, the UE performs a CAT2 LBT 220 before the scheduled time T0. A CAT2 LBT refers to an LBT without a random recoil. A CAT2 LBT may also be referred to as a one-time occurrence LBT. At time T0, after passing Petition 870250088930, dated 10 / 01 / 2025, page 72 / 237 Using LBT CAT2 220, the UE transmits a UL 222 communication signal based on the UL 212 scheduling grant. The UL 222 communication signal may include UL data and / or UL control information. For example, UL data may be carried in a PUSCH and UL control information may be carried in a PUCCH. UL control information may include scheduling requests, channel information (such as CSI reports), and / or confirmation / negative confirmation (ACK / NACK) feedback from Hybrid Automatic Repeat Request (HARQ).

[0052] In addition, BS transmits a UL 214 scheduling grant to schedule UE for another UL communication at a time T1 outside of COT 202. After receiving the UL 214 scheduling grant, UE performs a CAT4 230 LBT before the scheduled time T0. At time T1, after passing through the CAT4 230 LBT, UE transmits a UL 232 communication signal based on the UL 214 scheduling grant. In other words, UE gains a COT 204 outside of COT 202 from BS for the transmission of the UL 232 communication signal. The UL 214 scheduling grant and the UL 232 communication signal may be substantially similar to the 212 scheduling grant and the UL 232 communication signal, respectively.

[0053] The UE can perform LBT CAT2 220 for the transmission of the UL 222 communication signal based on the scheduling for the UL 222 communication signal being within COT 202. The UE can perform LBT CAT4 230 for the transmission of the UL 232 communication signal based on Petition 870250088930, dated 10 / 01 / 2025, page 73 / 237 26 / 79 scheduling for the UL 232 communication signal being outside of BS COT 202.

[0054] A COT (such as COTs 202 and / or 204) acquired from a CAT4 LBT (such as CAT4 LBTs 210 and / or 230) may be permitted to have a specific COT duration based on the regulations for the spectrum in use. For example, the COT duration may be dependent on the length of the contention window (such as a time duration) used for the CAT4 LBT. A transmit node may perform a random pullback by drawing a random number within a range of the contention window length and pullingback for a period of time based on the random number. The UE may set a counter with the drawn random number. If the channel remains inactive during the pullback period, the transmit node may transmit at the end of the pullback period (such as when the counter counts to zero). In one embodiment, the UE in Figure 2 may not use the entire duration of COT 204 to transmit the UL 232 communication signal.As an example, COT 204 may have a duration of about 6 milliseconds (ms), but the scheduled UL 232 communication signal may cover a duration of about 2 ms. Therefore, the remaining 4 ms may not be used.

[0055] Therefore, the present disclosure provides techniques for an UE to obtain a COT (such as, for example, COT 204) from a BS COT (such as, for example, COT 202) for a scheduled UL transmission (such as, for example, the UL 232 communication signal) to share the UE COT with the BS for DL ​​communication.

The COT 308 sharing module can be used for various aspects of the present disclosure, aspects of Figures 2 and 5-12. For example, the COT 308 sharing module is configured to receive a UL scheduling grant from a BS (such as BS 105 in Figure 1) that grants a UL schedule outside of a BS COT and performs a CAT4 LBT to acquire a COT before transmitting a UL communication signal according to the UL schedule, determine information to share a portion of the COT when the CAT4 LBT is performed, generate a UL communication signal that includes the COT sharing information, and / or transmit the UL communication signal according to the UL schedule.

Although shown as integrated together in the transceiver 310, the modem subsystem 312 and the RF unit 314 can be separate devices that are coupled together in the UE 115 to allow the UE 115 to communicate with other devices.

[0063] RF unit 314 can provide modulated and / or processed data, such as data packets (or, more generally, data messages that may contain one or more data packets and other information), to antennas 316 for transmission to one or Petition 870250088930, dated 10 / 01 / 2025, page 78 / 237 31 / 79 plus other devices.

[0065] Figure 4 is a block diagram of an exemplary BS 400 according to embodiments of the present disclosure. The BS 400 may be a BS 105 on the 100 network, as discussed above in Figure 1. As shown, the BS 400 may include a processor 402, a memory 404, a COT sharing module 408, a transceiver 410 which includes a modem subsystem 412 and an RF unit 414, and one or more antennas 416.

[0066] The 402 processor can have various features as a specific type of processor. For example, these can include a CPU, a DSP, an ASIC, a Petition 870250088930, dated 10 / 01 / 2025, page 79 / 237 32 / 79 controller, an FPGA device, another hardware device, a firmware device, or any combination thereof configured to perform the operations described herein. The 402 processor may also be implemented as a combination of computing devices, such as a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors together with a DSP core, or any other such configuration.

The COT sharing module 408 can be used for various aspects of the present disclosure, aspects of Figures 2 and 5-12. For example, the COT sharing module 408 is configured to transmit a UL scheduling grant to a UE (such as, for example, UE 115 or UE 300) that grants a UL scheduling outside of a COT from BS 400, receive a communication signal from UL, receive a communication signal from UL from BS based on the UL schedule, decode COT sharing information from the communication signal.

The 410 transceiver can be configured to be Petition 870250088930, dated 10 / 01 / 2025, p. 81 / 237 34 / 79 communicate bidirectionally with other devices, such as UEs 115 and / or other core network elements. The modem subsystem 412 can be configured to modulate and / or encode data according to an MCS, such as an LDPC encoding scheme, a turbo encoding scheme, a convolutional encoding scheme, a digital beamforming scheme, etc. The RF unit 414 can be configured to process (e.g., perform analog-to-digital or digital-to-analog conversion, etc.) modulated / encoded data from the modem subsystem 412 (in outgoing transmissions) or from transmissions originating from another source, such as UE 115 or 300. The RF unit 414 can also be configured to perform analog beamforming in conjunction with digital beamforming.Although shown as integrated together in transceiver 410, the modem subsystem 412 and / or the RF unit 414 may be separate devices that are coupled to the BS 105 to allow the BS 105 to communicate with other devices.

[0071] RF unit 414 can provide modulated and / or processed data, such as data packets (or, more generally, data messages that may contain one or more data packets and other information), to antennas 416 for transmission to one or more other devices. This may include, for example, transmitting information to complete attachment to a network and communication with a camped UE 115 or BS 400 according to the embodiments of the present disclosure. Antennas 416 may additionally receive data messages. Petition 870250088930, dated 10 / 01 / 2025, page 82 / 237 35 / 79 transmitted from other devices and provide the received data messages for processing and / or demodulation in the transceiver 410. The antennas 416 may include multiple antennas of similar or different designs, in order to support multiple transmission links.

[0072] In one embodiment, the BS 400 may include multiple 410 transceivers implementing different RATs (such as NR and LTE).

[0073] Figure 5 is a timing diagram showing a 500 scheme for sharing a COT associated with a scheduled UL transmission according to some embodiments of the present disclosure. The 500 scheme can be used by BSs, such as BS 105, and UEs, such as UE 115, in a network, such as network 100. In particular, a BS and a UE can use the 500 scheme for UL-to-DL COT sharing in a frequency spectrum (such as, for example, an unlicensed spectrum or a shared spectrum) shared by multiple network operating entities. In Figure 5, the geometric x-axis represents time in some arbitrary units. In the 500 scheme, a UE (such as UE 115 in Figure 1) can initiate a COT based on a UL schedule received from a BS (such as BS 105 in Figure 1) and share the COT with the Petition 870250088930, dated 10 / 01 / 2025, p. 83 / 237 36 / 79 BS for DL ​​communication. BS and UE can use LBT mechanisms substantially similar to the 200 scheme described in Figure 2 to acquire a COT.

[0074] As shown, BS acquires a COT 502. BS transmits a UL 514 scheduling grant on COT 502 to schedule UE for a UL transmission at a time T0 outside of BS's COT 502. UE performs a CAT4 530 LBT before the scheduled time T0. After passing through the LBT 530, UE gains a COT 504 and transmits a UL 532 communication signal that begins at the scheduled time T0 according to the UL 514 scheduling grant. COT 504 may include a longer duration than the duration of the UL 532 communication signal transmission. For example, COT 504 may end at time T2 based on a contention window length used to perform the CAT4 530 LBT.

[0075] Consequently, the UE can share COT 504 with the BS for DL ​​communication. In one embodiment, the UE includes the COT 534 sharing information in the UL 532 communication signal. The COT 534 sharing information may indicate that the BS is permitted to share the UE 504 COT for communication. The COT 534 sharing information may indicate a shareable portion of the UE 504 COT that begins at a time 506 (e.g., at time T1) with a duration of 508, as shown by the dashed and dotted box. In the context of 5G or NR, the UL 532 communication signal may be a PUSCH signal and the COT 534 sharing information may be a PUCCH signal or a UL control information (UCI) message. Petition 870250088930, dated 10 / 01 / 2025, page 84 / 237 37 / 79

[0076] After receiving the COT 534 sharing information, the BS performs a CAT2 LBT 540 and transmits a DL 542 communication signal for a period within the shareable duration 508. The DL 542 communication signal may include DL control information (such as DL scheduling grants) and / or DL ​​data. In one embodiment, the BS may be permitted to use the UE 504 COT for DL ​​and / or UL communications with the UE and may not be permitted to use the UE 504 COT for communication with another UE (such as UE 115 in Figure 1). In one embodiment, the BS may be permitted to use the COT of UE 504 for DL ​​communication with another UE (such as, for example, UE 115 in Figure 1) after communicating with the EU.

[0077] In one embodiment, the BS may be permitted to use the EU 504 COT for communications of a particular traffic priority. For example, the UL 532 communication signal may include UL data of a particular traffic priority. The BS may be permitted to use the EU 504 COT to transmit DL data of a higher priority than the UL data or DL ​​data of a priority equal to the UL data. UL.

[0078] Figure 6 is a timing diagram showing a 600 scheme for sharing a COT associated with a scheduled UL transmission according to some embodiments of the present disclosure. The 600 scheme can be used by BSs, such as BS 105, and UEs, such as UE 115, in a network, such as network 100. In Petition 870250088930, dated 10 / 01 / 2025, p. 85 / 237 38 / 79 In particular, a BS and a UE can use the 600 scheme for UL-to-DL COT sharing in a frequency spectrum (such as, for example, an unlicensed spectrum or a shared spectrum) shared by multiple network operating entities. In Figure 6, the geometric x-axis represents time in some arbitrary units. The 600 scheme is substantially similar to the 500 scheme and shows a scenario where a BS (such as, for example, BS 105 in Figure 1) can schedule a UE (such as, for example, UE 115 in Figure 1) with sequential UL transmissions outside of a BS COT. The BS and UE can use LBT mechanisms substantially similar to those of the 200 scheme described in Figure 2 to acquire a COT.

[0079] As shown, BS acquires a COT 602. BS transmits a plurality of UL 614 scheduling grants (shown as 614a, 614b, and 614c) on COT 602 to schedule the UE for UL transmissions in consecutive periods or transmission partitions off COT 502. Consecutive periods begin at time T0. The UE performs a CAT4 LBT 630 before the scheduled time T0. After passing through the LBT 630, the UE gains a COT 604 and transmits the UL communication signals 632a, 632b, and 632c (such as, for example, including UL data and / or UL control information) according to the UL 614a, 614b, and 614c scheduling grants, respectively.

[0080] Similar to scheme 500, the UE can share a portion of COT 604 after the last UL 632c communication signal. In one embodiment, the UE can include the COT 634 sharing information in one of the sequential UL communication signals 632a, 632b, Petition 870250088930, dated 10 / 01 / 2025, p. 86 / 237 39 / 79 632c. As shown, the UL 632a communication signal may include the COT 634 sharing information, and the other UL 632b and 632c communication signals do not include the COT 634 sharing information. The COT 634 sharing information may be substantially similar to the COT 534 sharing information. For example, the COT 634 sharing information may indicate a shareable portion of the EU 604 COT that begins at a time 606 (such as time T1) with a duration of 608, as shown by the dashed dotted box.

[0081] BS can share the UE 604 COT using mechanisms substantially similar to those of scheme 500 described in Figure 5. For example, BS performs a CAT2 640 LBT. After passing through the CAT2 640 LBT, BS transmits a DL 642 communication signal (such as, for example, including DL data and / or DL ​​control information) to the UE during a period within the shareable duration 608.

[0082] In one embodiment, the BS may include a trigger or a request for COT 634 sharing information in a corresponding UL 614 scheduling grant. For example, the BS may include a request for COT 634 sharing information in the UL 614a scheduling grant and may not include a request for COT 634 sharing information in the UL 614b and 614c scheduling grants.

[0083] In one embodiment, BS may group a COT-sharing UCI with other transmissions. Petition 870250088930, dated 10 / 01 / 2025, p. 87 / 237 40 / 79 of UTI. For example, the BS may include a trigger for a grouped UTI in the scheduling grant of UL 614a. The trigger may request that the UE transmit COT 634 sharing information and ACK / NACK feedback and / or channel information (such as, for example, CSI reports). In some examples, ACK / NACK feedback may be associated with HARQ processes used for DL ​​data transmissions and retransmissions.

[0084] Figure 7 is a timing diagram showing a 700 scheme for sharing a COT associated with a scheduled UL transmission according to some embodiments of the present disclosure. The 700 scheme can be used by BSs, such as BS 105, and UEs, such as UE 115, in a network, such as network 100. In particular, a BS and a UE can use the 700 scheme for UL-to-DL COT sharing in a frequency spectrum (such as, for example, an unlicensed spectrum or a shared spectrum) shared by multiple network operating entities. In Figure 7, the geometric x-axis represents time in some arbitrary units. The 700 scheme is substantially similar to the 500 scheme. However, in the 700 scheme, a BS (such as, for example, BS 105 in Figure 1) may initially grant a UL schedule for a transmission outside of a BS COT, but may subsequently contest and win another COT before the UL schedule, causing the UL schedule to fall back to the BS COT.BS and UE can use LBT mechanisms substantially similar to the 200 scheme described in Figure 2 to acquire a COT. Petition 870250088930, dated 10 / 01 / 2025, page 88 / 237 41 / 79

[0085] As shown, BS acquires a COT 702. BS transmits a UL 714 scheduling grant on COT 702 to schedule the UE for a UL transmission at a T2 time outside of BS 702's COT. After detecting the UE 714 scheduling grant, the UE can generate a UL 732 communication signal based on the UL 714 scheduling grant and can include COT 734 sharing information in the UL 732 communication signal. The UE can determine COT 734 sharing information based on the UL 714 scheduling grant. For example, the UE can determine a potential COT duration if the UE passes through a CAT4 LBT similar to CAT4 LBTs 230, 530, and 630. The UE can determine a start time 706 (such as a T3 time) and / or a duration 708 for a part (shown as a box). dashed-dotted line) of the potential COT that can be shared with the BS using a mechanism similar to the 500 scheme described above in Figure 5.The EU can generate COT 734 sharing information based on the initial time specified and the duration specified for the shareable portion of the COT.

[0086] At time T0, BS bids for another COT before the scheduled time T2, performing a CAT4 710 LBT similar to the CAT4 210 LBT at time T0. At time T1, after passing through the CAT4 710 LBT, BS wins another COT 702 (shown as 702b). Thus, the initial UL schedule that begins at time T2 granted by the UL schedule grant 714 is no longer outside of a BS COT. Instead, the UL schedule is within the new BS COT 702b. The UE can detect the start of the BS COT 702b, Petition 870250088930, dated 10 / 01 / 2025, page 89 / 237 42 / 79 for example, monitoring reference signals (such as DMRSs) and / or COT structure information signals. A COT structure information signal may include a COT duration and / or partition format information for the partitions within the COT.

[0087] Upon detecting the start of the BS 702b COT and that the UL schedule (such as, for example, scheduled by the UL 714 scheduling grant) is within the BS 702b COT, the UE may perform a CAT2 720 LBT similar to the CAT2 220 LBT or no LBT before transmitting the UL 7 32 communication signal at the scheduled time T2. The UE may determine whether to perform a CAT2 720 LBT or no LBT based on a transmission gap between the scheduled time T2 and a last transmission on the channel. When the transmission gap is short (for example, less than about 16 microseconds (ps)), the UE cannot perform a LBT before transmitting the UL 732 communication signal, as shown by 752. When the transmission gap is long (for example, longer than about 16 ps), the UE can perform a CAT2 720 LBT before transmitting the UL 732 communication signal, as shown by 750.

[0088] Since the UL schedule to transmit the UL 732 communication signal returns to the BS 702b COT, the UE may not be allowed to share the initially calculated shareable COT with the BS, as shown by the cross-marking. Generating the UL 732 communication signal may take some time. The UE may have already generated the UL communication signal. 732 including COT sharing information 734 before detecting the start of COT from BS 702b. Thus, the EU Petition 870250088930, dated 10 / 01 / 2025, page 90 / 237 43 / 79 can proceed to transmit the UL 732 communication signal generated at the scheduled time T2. After receiving the UL 732 communication signal that includes the COT 734 sharing information, BS can disregard the COT 734 sharing information when the UL 732 communication signal is received within a BS 702b COT duration. In some instances, when there is sufficient time between the time the UE detected the start of the BS 702b COT and the start of the UL schedule, the UE can generate another UL 732 communication signal without the COT 734 sharing information and transmit the UL 732 communication signal without the COT 734 sharing information.

[0089] Figure 8 is a timing diagram showing an 800 scheme for sharing a COT associated with a scheduled UL transmission according to some embodiments of the present disclosure. The 800 scheme can be used by BSs, such as BS 105, and UEs, such as UE 115, in a network, such as network 100. In particular, a BS and a UE can use the 800 scheme for UL-to-DL COT sharing in a frequency spectrum (such as, for example, an unlicensed spectrum or a shared spectrum) shared by multiple network operating entities. In Figure 8, the geometric x-axis represents time in some arbitrary units. The 800 scheme is substantially similar to the 500 scheme. However, the 800 scheme provides a UE (such as, for example, UE 115 in Figure 1) with the flexibility to modify a traffic priority assigned by a BS. Petition 870250088930, dated 10 / 01 / 2025, p. 91 / 237 44 / 79 (such as BS 105 in Figure 1) when a UL schedule is outside of a BS COT. BS and UE can use LBT mechanisms substantially similar to the 200 scheme described in Figure 2 to acquire a COT.

[0090] As shown, BS acquires a COT 802. BS transmits a UL 814 scheduling grant on COT 802 to schedule the UE for a UL transmission at a time T0 outside of BS 802's COT. The UL 814 scheduling grant may include a traffic priority or data priority assigned to the UL transmission, in addition to transmission configuration resources and parameters.

[0091] In a first scenario 840, the UE can perform a CAT4 830a LBT before the scheduled time T0. The UE can perform the CAT4 830a LBT by configuring a random fallback period based on a contention window length associated with the assigned traffic priority. After passing through the CAT4 830a LBT, the UE gains a COT 804a and transmits a UL 832a communication signal including UL data of the assigned traffic priority or priority class that begins at the scheduled time T0. The UE can include COT 834a sharing information in the UL 832a communication signal using mechanisms similar to those of scheme 500 described in Figure 5. The COT 834a sharing information can indicate a shareable portion of the UE's COT 804a that begins at time 806a (for example, at time T1) with a duration of 808a, as shown by the dashed-dotted box.

[0092] In a second scenario 842, the EU may determine to transmit the UL data from another priority of Petition 870250088930, dated 10 / 01 / 2025, page 92 / 237 45 / 79 traffic using the UL scheduling granted by the UL scheduling grant 814. The UE can determine the use of the granted UL scheduling for a lower traffic priority than the assigned priority. The UE performs a CAT4 830b LBT based on a contention window length associated with the determined traffic priority. The contention window length for a lower traffic priority can be longer. As shown, the UE performs the CAT4 830b LBT with a longer contention window length than the CAT4 830a LBT. After passing through the CAT4 830b LBT, the UE gains a COT 804b. The COT 804b has a longer duration than the COT 804a based on the CAT4 830b LBT with a longer contention window length. The UE can transmit a UL 832b communication signal including UL data of the lowest determined traffic priority that begins at the scheduled time T0.The UE may include COT 834b sharing information in the UL 832b communication signal using mechanisms similar to those of the 500 scheme described in Figure 5. The COT 834b sharing information may indicate a shareable portion of the UE's COT 804b that begins at time 8 0 6b (for example, at time T1) with a duration of 808b, as shown by the dashed-dotted box. The COT 834b sharing information may additionally indicate the traffic priority of the UL data included in the UL 832b communication signal and / or any other information related to the transmission of the UL 832b communication signal. The BS may decode the UL data in accordance with a. Petition 870250088930, dated 10 / 01 / 2025, page 93 / 237 46 / 79 additional traffic priority and / or other transmission information.

[0093] In a third scenario 844, the BS can contest another COT before the scheduled time T0 and can win another COT 802 (shown as 802b). Thus, the UL schedule granted by the UL schedule grant 814 is within the COT of BS 802b. After detecting COT 802b and determining that the UL schedule is within the COT of BS 802b, the UE can perform a CAT2 LBT 820 and transmit a UL communication signal 832c that starts at the scheduled time T0. The UE may not be allowed to change the traffic priority when the UL schedule returns to the COT of BS 802b. Thus, the communication signal 832c includes UL data from the assigned traffic priority. Similar to scheme 700, no UL-to-DL COT sharing is allowed when the UL schedule returns to the BS 802b COT. Thus, the UL 832c communication signal may not include COT sharing information.In some instances, after BS acquired COT 802b, BS may assign UE a different traffic priority for UL scheduling than was previously granted by the UL 814 scheduling concession.

[0094] Figure 9 shows a UL 900 transmission component according to some embodiments of the present disclosure. The UL 900 transmission component can be implemented by a UE (such as, for example, the UE 115 in Figure 1 or the UE 300 in Figure 3) for UL transmission in a network (such as, for example, the 100 network). In particular, the UL 900 transmission component can be included in Petition 870250088930, dated 10 / 01 / 2025, p. 94 / 237 Figure 3 shows the 4Ί / Ί9 COT sharing module 308. The UL 900 transmission component includes a channel access component 910, a packet generation component 920, a BS COT detection component 930, and a selection component 940. The channel access component 910, the packet generation component 920, the BS COT detection component 930, and the selection component 940 can be implemented using a combination of hardware and / or software.

[0095] The 910 channel access component is configured to perform multiple channel release assessments (CCAs), which include LBTs of different LBT types and / or different contention window lengths. For example, the 910 channel access component is configured to perform a CAT4 912 LBT with a first contention window length, a CAT4 912 LBT with a second contention window length, and a CAT2 914 LBT. In some examples, the 910 channel access component may use multiple counters to perform random backoffs of varying backoff periods, as described above in Figure 2.

[0096] The packet generation component 920 is configured to generate multiple data packets of different priority classes (such as traffic priorities) and / or different sizes. For example, the packet generation component 920 is configured to generate a data packet 922 of a first priority class and a data packet 924 of a second priority class. Petition 870250088930, dated 10 / 01 / 2025, page 95 / 237 48 / 79

[0097] BS TOC detection component The 930 is configured to detect the beginning and / or end of a BS COT (such as COTs 202, 502, 602, 702, and / or 802). The BS 930 COT detection component can detect the presence of a BS COT by monitoring DMRSs and / or any BS COT structure information.

[0098] In one example, when the UE receives a UL scheduling grant (such as, for example, UL scheduling grants 214, 514, 614, 714 and / or 814) For a UL transmission outside of a BS COT (such as BS 105 in Figure 1), the UE can configure the channel 910 access component to perform a CAT4 912 LBT using a contention window length corresponding to a traffic priority (such as P1) assigned by the UL scheduling grant. The UE can configure the channel 910 access component to perform a CAT4 914 LBT using a contention window length corresponding to a traffic priority (such as P2) lower than the assigned traffic priority. The UE can configure the channel 910 access component to perform a CAT2 916 LBT.

[0099] The UE can configure the 920 packet generation component to generate a 922 data packet from assigned P1 traffic priority data. The 920 packet generation component can determine the size of the 922 data packet based on the UL scheduling grant (such as assigned MCSs and the number of allocated RBs). The UE can configure the 920 packet generation component to generate a packet of Petition 870250088930, dated 10 / 01 / 2025, page 96 / 237 49 / 79 data 924 from lower priority P2 traffic data. The packet generation component 920 can generate data packet 924 with a larger data size than data packet 922.

[0100] The UE can configure the BS 930 TOC detection component to monitor a TOC from the BS and determine if a TOC that includes the scheduled UL is detected from the BS.

[0101] Selection component 940 is configured to determine whether to transmit data packet 922 or data packet 924 based on the results of LBT CAT4 912, LBT CAT4 914 and LBT CAT2 916 and whether the UL schedule is within a BS COT.

[0102] For example, when the UL schedule is outside the COT of a BS and LBT CAT4 912 is performed, the selection component 940 can select data packet 922 for transmission in the scheduled time period. When the UL schedule is outside the COT of a BS and LBT CAT4 914 is performed, the selection component 940 can select data packet 924 for transmission in the scheduled time period. When the UL schedule returns to a BS COT and LBT CAT4 912 is performed, the selection component 940 can select data packet 922 for transmission in the scheduled time period.

[0103] In general, the 910 channel access component can be configured to perform any suitable number of LBTs of any suitable contention window lengths, and the 920 packet generation component can be configured to generate any suitable number of data packets based on certain Petition 870250088930, dated 10 / 01 / 2025, page 97 / 237 50 / 79 hypotheses in association with LBTs when receiving an UL appointment outside of a BS's COT.

[0104] Figure 10 is a timing diagram showing a 1000 scheme for sharing a COT associated with a scheduled UL transmission according to some embodiments of the present disclosure. The 1000 scheme can be used by BSs, such as BSs 105, and UEs, such as UEs 115, in a network, such as network 100. In particular, a BS and a UE can use the 1000 scheme for UL-to-DL COT sharing in a frequency spectrum (such as, for example, an unlicensed spectrum or a shared spectrum) shared by multiple network operating entities. In Figure 10, the geometric x-axis represents time in some arbitrary units. In scheme 1000, a BS (such as BS 105 in Figure 1) can determine the COT sharing information to share a COT from an UE (such as UE 115 in Figure 1) instead of using the COT sharing information provided by the UE.BS and UE can use LBT mechanisms substantially similar to the 200 scheme described in Figure 2 to acquire a COT.

[0105] As shown, BS acquires a COT 1002. BS transmits a UL 1014 scheduling grant on COT 1002 to schedule UE for a UL transmission at a time T0 outside of COT 1002. After detecting the UL 1014 scheduling grant, UE performs a CAT4 LBT 1030 before the scheduled time T0. After passing through the LBT 1030, UE gains a COT 1004 and transmits a signal of Petition 870250088930, dated 10 / 01 / 2025, p. 98 / 237 51 / 79 UL communication in accordance with UL scheduling grant 1014.

[0106] Since the UL 1014 scheduling grant is determined by BS, BS can determine a UE 1004 COT duration and a shareable portion of the UE 1004 COT based on the UL scheduling, as shown by arrow 1001. Thus, BS can determine when the shareable portion starts (e.g., the initial time T1 1006) and a duration 1008 of the shareable portion. BS can perform a CAT2 1040 LBT and transmit a DL 1042 communication signal on the shareable portion of the UE 1004 COT.

[0107] Figure 11 is a timing diagram showing an 1100 scheme for sharing a COT associated with a scheduled UL transmission according to some embodiments of the present disclosure. The 1100 scheme can be used by BSs, such as BSs 105, and UEs, such as UEs 115, in a network, such as network 100. In particular, a BS and a UE can use the 1100 scheme for UL-to-DL COT sharing in a frequency spectrum (such as, for example, an unlicensed spectrum or a shared spectrum) shared by multiple network operating entities. In Figure 11, the geometric x-axis represents time in some arbitrary units. Scheme 1100 is substantially similar to scheme 1000 and shows a scenario where a BS (such as BS 105 in Figure 1) can schedule a UE (such as UE 115 in Figure 1) with sequential UL transmissions outside of a BS COT. BS and UE can use Petition 870250088930, dated 10 / 01 / 2025, p. 99 / 237 52 / 79 LBT mechanisms substantially similar to those of scheme 200 described in Figure 2 for acquiring a COT.

[0108] As shown, BS acquires a COT 1102. BS transmits a plurality of UL 1114 scheduling grants (shown as 1114a and 1114b) on COT 1102 to schedule the UE for UL transmissions in consecutive periods or transmission partitions outside of BS 1200's COT. For example, UL 1114a scheduling grant is for a UL schedule at time T0 and UL 1114b scheduling grant is for a UL schedule at time T1. The UE performs a CAT4 1130 LBT before the scheduled time T0. The CAT4 1130 LBT may fail and therefore the UE may not be able to transmit a UL 1032a communication signal scheduled by UL 1114 scheduling grant, as shown by the cross representation. The UE can pass through a CAT4 LBT later, before time T1. Thus, the UE transmits a UL 1132b communication signal starting at time T1 based on the UL 1114b scheduling grant, as shown by the control mark.

[0109] In a first option, the BS can determine the start of a UE COT (such as COT 1104a) based on the scheduled time T0 and determine a shareable COT (such as one that starts at time T2 with a duration of 1008a) from the UE COT 1104a. The BS can transmit a DL communication signal similar to the DL communication signals 542, 642, and 1042 during COT 1104a. However, since the UE initially failed on LBT CAT4 1130, the UE gains a COT 1104b that instead starts at time T1, and thus the BS can potentially Petition 870250088930, dated 10 / 01 / 2025, page 100 / 237 53 / 79 share a longer section (as, for example, in COT 1104b).

[0110] In a second option, the BS can determine the start of a UE COT based on a DMRS detection from the UE and / or a UCI decoding received from the UE. Thus, the BS can detect a DMRS and / or UCI from the UL 1032b communication signal. UCI decoding may include cyclic redundancy checking (CRC) and therefore may have low false detection. DMRS detection may have lower detection reliability than UCI decoding. As such, the BS can determine that the UE initiated a COT (such as COT 1004b) at time T1 and determine a shareable COT (such as starting at time T2) from the UE's COT 1104b.

[0111] In some cases, the UE may transmit the UL 1132a communication signal, but the BS may fail to detect the UL 1132a communication signal. Thus, the BS may incorrectly determine that the UE COT starts at time T1 instead of time T0. In some modes, the BS may select between the first option and the second option based on a traffic priority assigned for scheduling at time T0 and T1.

[0112] Figure 12 is a flow diagram of a 1200 communication method according to some embodiments of the present disclosure. The steps of the 1200 method can be performed by a computing device (such as, for example, a processor, processing circuit and / or other suitable component) of a wireless communication device or other suitable means. Petition 870250088930, dated 10 / 01 / 2025, page 101 / 237 54 / 79 to perform the steps. For example, a wireless communication device, such as the UE 115 or UE 300, may use one or more components, such as the processor 302, memory 304, COT sharing module 308, transceiver 310, modem 312, one or more antennas 316, and the transmission component UL 900 to perform the steps of method 1200. In another example, a wireless communication device, such as the BS 105 or BS 400, may use one or more components, such as the processor 402, memory 404, COT sharing module 408, transceiver 410, modem 412, and one or more antennas. 416, to execute the steps of method 1200. Method 1200 may use mechanisms similar to those of schemes 200, 500, 600, 700, 800, 1000 and / or 1100 described in relation to Figures 2, 5, 6, 7, 8, 10 and / or 11, respectively. As shown, the 1200 method includes a number of enumerated steps, but variations of the 1200 method may include additional steps before, after, and between the enumerated steps. In some variations, one or more of the enumerated steps may be omitted or performed in a different order.

[0113] In step 1210, method 1200 involves communicating, via a first wireless communication device with a second wireless communication device, a first UL scheduling grant. The first UL scheduling grant may be similar to UL scheduling grants 514, 614, 714, 814, 1014 and / or 1114.

[0114] In step 1220, the method includes communicating, via the first wireless communication device Petition 870250088930, dated 10 / 01 / 2025, page 102 / 237 55 / 79 with the second wireless communication device, a first UL communication signal based on the first UL scheduling grant (such as, for example, UL communication signals 532, 632, 732, 832a, 832b, 1032, 1132a and / or 1132b) during a first COT (such as, for example, COTs 504, 604, 804, 1004 and / or 1104). The first COT is based on an eCCA (such as, for example, the CAT4 530, 630, 730, 830, 1030 and / or 1130 LBTs) associated with the first UL communication signal.

[0115] In step 1230, the method involves communicating, by the first wireless communication device with the second wireless communication device, a DL communication signal (such as, for example, the DL communication signals during the first COT based on the COT sharing information associated with the first COT.

[0116] In one embodiment, the first wireless communication device corresponds to a UE (such as, for example, UE 115 and / or UE 300) and the second wireless communication device corresponds to a BS (such as, for example, BS 105 and / or BS 400). The first wireless communication device communicates the first UL scheduling grant upon receiving, from the second wireless communication device, the first UL scheduling grant during a COT (such as, for example, COTs 502, 602, 702, 802, 1002 and / or 1102) from the second wireless communication device. The first wireless communication device communicates the first UL communication signal upon transmitting, to the second wireless communication device, the first signal of Petition 870250088930, dated 10 / 01 / 2025, page 103 / 237 56 / 79 UL communication. The first COT is associated with the first wireless communication device and is located outside a COT of the second wireless communication device.

[0117] In one embodiment, the first wireless communication device corresponds to a BS (such as, for example, BS 105 and / or BS 400) and the second wireless communication device corresponds to a UE (such as, for example, UE 115 or UE 300). The first wireless communication device communicates the first UL scheduling grant by transmitting, to the second wireless communication device, the first UL scheduling grant during a COT of the second wireless communication device. The first wireless communication device communicates the first UL communication signal by receiving, from the second wireless communication device, the first UL communication signal. The first COT is associated with the second wireless communication device and is located outside a COT of the first wireless communication device.

[0118] In one embodiment, the UL communication signal includes COT sharing information (such as, for example, COT sharing information 534, 634, 734 and / or 834). In one embodiment, the UL communication signal is communicated during a first part of the first COT and the DL communication signal is communicated during a shared part of the first COT. The first part is different from the shared part. The sharing information Petition 870250088930, dated 10 / 01 / 2025, p. 104 / 237 57 / 79 of COT include at least one of an initial time (such as, for example, initial time 506, 706, 806, 1006 and / or 1106) or a duration (such as, for example, duration 508, 708, 808, 1008 and / or 1108) of the first COT. In one embodiment, the first UL scheduling grant indicates a first traffic priority. The UL communication signal additionally includes UL data associated with a second traffic priority different from the first traffic priority, and the COT sharing information indicates the second traffic priority. In one embodiment, the first wireless communication device performs eCCA based on the second traffic priority.In one embodiment, the first wireless communication device communicates with the second wireless communication device a plurality of scheduling grants (such as, for example, UL 632a, 632b, and / or 632c scheduling grants) to communicate a plurality of UL communication signals (such as, for example, UL 632a, 632b, and / or 632c communication signals) in consecutive periods, the plurality of scheduling grants including the first UL scheduling grant. The first wireless communication device communicates with the second wireless communication device a second UL communication signal from the plurality of UL communication signals based on a second UL scheduling grant from the plurality of scheduling grants during a period of consecutive periods within the first COT.In one modality, the first UL scheduling grant includes a request for COT sharing information, and in which... Petition 870250088930, dated 10 / 01 / 2025, page 105 / 237 58 / 79 second UL scheduling grant does not include a request for COT sharing information. In one embodiment, the first UL scheduling grant includes a request for UL control information that includes COT sharing information and at least one ACK / NACK feedback or channel information.

[0119] In one embodiment, the first wireless communication device receives, from the second wireless communication device, a second UL scheduling grant outside of a COT from the second wireless communication device, the second UL scheduling grant indicating a first traffic priority. The first wireless communication device performs a plurality of LBTs based on different contention window lengths. The first wireless communication device generates a first UL data block based on the first traffic priority. The first wireless communication device generates a second UL data block based on a second traffic priority different from the first traffic priority.The first wireless communication device transmits, to the second wireless communication device in response to the second UL scheduling grant, either the first UL data block or the second UL data block based on at least one of the plurality of CCAs or a detection of another COT by the second wireless communication device.

[0120] In one embodiment, the first wireless communication device determines the COT sharing information based on the first grant. Petition 870250088930, dated 10 / 01 / 2025, page 106 / 237 59 / 79 UL scheduling. In one embodiment, the first wireless communication device communicates the DL communication signal by transmitting, to the second wireless communication device, the DL communication signal based, at least in part, on the determined COT sharing information. In one embodiment, the DL communication signal is communicated based on the detection of the first UL communication signal. In one embodiment, detection is based on the detection of at least one of a reference signal or UL control information associated with the first UL communication signal.In one embodiment, the first wireless communication device transmits to the second wireless communication device a plurality of scheduling grants to communicate a plurality of UL communication signals in consecutive periods outside of a COT from the first wireless communication device, the plurality of scheduling grants including the first UL scheduling grant. In another embodiment, the DL communication signal is communicated based on the detection of one or more UL communication signals from the plurality of UL communication signals.
