[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 750,033, filed on October 24, 2018, entitled “QUALITY OF SERVICE MAPPING FOR TIME-SENSITIVE NETWORK TRAFFIC IN A WIRELESS COMMUNICATION SYSTEM,” and U.S. Non-Provisional Patent Application No. 16 / 660,176, filed on October 22, 2019, entitled “QUALITY OF SERVICE MAPPING FOR TIME-SENSITIVE NETWORK TRAFFIC IN A WIRELESS COMMUNICATION SYSTEM,” which are hereby expressly incorporated herein by reference. Technical Field

[0003] Various aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for quality of service mapping for time sensitive network traffic in wireless communication systems. Background Art

[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can 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 / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard released by the Third Generation Partnership Project (3GPP).

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

[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at the city, country, region, and even global level. New Radio (NR), also known as 5G, is an enhanced set of LTE mobile standards released by the Third Generation Partnership Project (3GPP). NR is designed to better integrate with other open standards by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation, so as to better support mobile broadband Internet access. However, as the demand for mobile broadband access continues to grow, there is a need for further improvements to LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunication standards that adopt these technologies. Summary of the invention

[0026] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. On the contrary, these aspects are provided so that the present disclosure will be comprehensive and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. Based on the teachings of this article, it should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect disclosed herein, whether it is implemented independently of any other aspect of the present disclosure or implemented in combination with any other aspect of the present disclosure. For example, using any number of aspects set forth herein, a device can be implemented or a method of practice can be implemented. In addition, aspects of the present disclosure are intended to cover such devices or methods: the device or method is implemented using other structures, functions, or structures and functions other than or different from the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be embodied by one or more elements of the claims.

[0027] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the detailed description below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0028] It should be noted that although various aspects may be described herein using terms commonly associated with 3G and / or 4G wireless technologies, various aspects of the present disclosure may be applied to communication systems based on other generations, such as 5G and later technologies (including NR technologies).

[0029] Figure 11 is a schematic diagram showing a network 100 in which various aspects of the present disclosure may be practiced. The network 100 may be an LTE network or some other wireless network such as a 5G or NR network. The wireless network 100 may include a plurality of BSs 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and is also referred to as a base station, NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0030] A BS may provide communication coverage for macro cells, pico cells, femto cells, and / or other types of cells. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UEs with service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown in , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) types of cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0031] In some aspects, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of the mobile BS. In some examples, the BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in access network 100 via various types of backhaul interfaces, such as direct physical connections, virtual networks, and / or the like using any suitable transport network.

[0032] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and transmit data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that relays transmissions for other UEs. Figure 1 In the example shown in FIG. 1 , a relay station 110r may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay station may also be referred to as a relay BS, a relay base station, a relay, or the like.

[0033] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0034] The network controller 130 may be coupled to a set of BSs and may provide coordination and control for the BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other (eg, directly or indirectly) via a wireless or wired backhaul.

[0035] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. UEs may also be referred to as access terminals, terminals, mobile stations, subscriber units, stations, etc. UEs may be cellular phones (e.g., smart phones), personal digital assistants (PDAs), wireless modems, wireless communication devices, handheld devices, laptop computers, cordless phones, wireless local loop (WLL) stations, tablet computers, cameras, gaming devices, netbooks, smartbooks, ultrabooks, medical devices or equipment, biometric sensors / devices, wearable devices (smart watches, smart clothing, smart glasses, smart wristbands, smart jewelry (e.g., smart rings, smart bracelets)), entertainment devices (e.g., music or video devices or satellite radios), vehicle components or sensors, smart meters / sensors, industrial manufacturing equipment, global positioning system devices, or any other suitable device configured to communicate via wireless or wired media.

[0036] Some UEs may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices (such as sensors, meters, monitors, location tags, etc.), which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide, for example, a connection to a network (e.g., a wide area network such as the Internet or a cellular network) or to a network via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as customer premises equipment (CPE). UE 120 may be included in a housing that houses various components of UE 120 (such as a processor component, a memory component, etc.).

[0037] Generally, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks with different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0038] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more side link channels (e.g., without using base station 110 as an intermediary for communicating with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, etc. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0039] As indicated above, Figure 1 This is provided merely as an example. Other examples are possible and may differ from the examples described above. Figure 1 as described.

[0040] Figure 2 1 shows a block diagram of a base station 110 and a UE 120. The base station 110 may be Figure 1 UE 120 may be one of the base stations in Figure 1Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where T≧1 and R≧1 in general.

[0041] At the base station 110, the transmit processor 220 may receive data from the data source 212 for one or more UEs, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and demodulate) data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., semi-static resource partitioning information (SRPI)), etc. and control information (e.g., CQI requests, grants, upper layer signaling, etc.), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t may be transmitted via T antennas 234a to 234t, respectively. According to various aspects described in more detail below, position coding may be used to generate synchronization signals to convey additional information.

[0042] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) received signals to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. Receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of UE 120 may be included in a housing.

[0043] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 (if applicable), further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110. At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 (if applicable), and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide decoded data to a data sink 239 and decoded control information to a controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0044] Controller / processor 240 of base station 110, controller / processor 280 of UE 120, controller / processor 290 of network controller 130, and / or Figure 2Any other component of the may perform one or more techniques associated with quality of service mapping for time-sensitive network services in a wireless communication system, as described in more detail elsewhere herein. For example, controller / processor 240 of base station 110, controller / processor 280 of UE 120, controller / processor 290 of network controller 130, and / or Figure 2 Any other component may perform or direct e.g. Figure 8 Processing 800, Fig. 9 The operations of process 900 and / or other processes described herein may be performed. Memories 242, 282, and 292 may store data and program codes for base station 110, UE 120, and network controller 130, respectively. Scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0045] In some aspects, the network controller 130 may include: a component for receiving a time-sensitive network (TSN) service configuration, the configuration indicating the duration of a gated open state of a TSN service flow and the periodicity of the gated open state; a component for configuring one or more QoS parameters associated with a wireless communication system for a quality of service (QoS) flow to carry the TSN service flow, wherein the one or more QoS parameters are configured at least in part based on one or more TSN capability parameters associated with the network controller 130 and at least one of the duration or periodicity of the gated open state; a component for transmitting the one or more QoS parameters to a base station of the wireless communication system, etc. In some aspects, the one or more TSN capability parameters associated with the network controller 130 may be associated with the wireless communication system. As a result, the one or more TSN capability parameters may depend on one or more capabilities of the wireless communication system. For example, different wireless communication systems using the network controller 130 may have different TSN capability parameters, depending on various parameters such as supported subcarrier spacing, bandwidth, backhaul quality, etc. In some aspects, such a component may include a combination of Figure 2 One or more components of network controller 130 are described.

[0046] In some aspects, the base station 110 may include: a component for receiving an indication of one or more quality of service (QoS) parameters associated with a wireless communication system for a quality of service (QoS) flow to carry a time sensitive network (TSN) service, wherein the one or more QoS parameters are configured based at least in part on one or more TSN capability parameters and at least one of a duration of a gated open state for the TSN service flow or a periodicity of occurrence of the gated open state; a component for processing the TSN service flow based at least in part on the one or more QoS parameters, etc. In some aspects, such a component may include a combination of Figure 2One or more components in base station 110 are described.

[0047] As indicated above, this is provided only as an example Figure 2 Other examples are possible and may differ from those described with respect to Figure 2 as described.

[0048] Figure 3 An example logical architecture of a distributed RAN 300 is shown in accordance with various aspects of the present disclosure.

[0049] The 5G access node 306 may include an access node controller (ANC) 302. The ANC 302 may be a central unit (CU) of the distributed RAN 300. The backhaul interface to the next generation core network (NG-CN) 304 may terminate at the ANC 302. The backhaul interface to the adjacent next generation access node (NG-AN) may terminate at the ANC 302. The ANC 302 may include one or more TRPs 308 (which may also be referred to as BS, NR BS, Node B, 5G NB, AP, gNB, or some other terminology). As described above, the TRP 308 may be used interchangeably with a "cell". In some aspects, multiple TRPs 308 may be included in a single base station 110. Additionally or alternatively, different TRPs 308 may be included in different base stations 110. In some aspects, the network controller 130 may include the ANC 302.

[0050] The TRP 308 may be a distributed unit (DU). The TRP 308 may be connected to a single ANC 302 or multiple ANCs 302. For example, for RAN sharing, Radio as a Service (RaaS), and service-specific AND deployments, the TRP 308 may be connected to multiple ANCs 302. The TRP 308 may include one or more antenna ports. The TRP 308 may be configured to serve traffic to the UE 120 individually (e.g., using dynamic selection) or jointly (e.g., using joint transmission).

[0051] The local architecture of RAN 300 can be used to illustrate the fronthaul definition. The architecture can be defined to support fronthaul solutions across different deployment types. For example, the architecture can be based at least in part on transmission network capabilities (e.g., bandwidth, latency and / or jitter). The architecture can share features and / or components with LTE. According to various aspects, the next generation AN (NG-AN) 310 can support dual connectivity with NR. NG-AN 30 can share a common fronthaul for LTE and NR. The architecture can enable collaboration between and among TRPs 308. For example, collaboration can be preset within TRP 308 and / or across TRP 308 via ANC 302. In some aspects, a non-TRP interface may be required / present.

[0052] In some aspects, dynamic configuration of discrete logical functions may be present within the architecture of the RAN 300. Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), Medium Access Control (MAC) protocols, etc. may be adaptably placed at the ANC 302 or the TRP 308. According to various aspects, the base station 110 may include a central unit (CU) (e.g., the ANC 302) and / or one or more distributed units (e.g., one or more TRPs 308).

[0055] A centralized core network unit (C-CU) 402 may host core network functions. C-CU 402 may be centrally deployed. The functions of C-CU 402 may be offloaded (e.g., to Advanced Wireless Services (AWS)) to handle peak capacity. A centralized RAN unit (C-RU) 404 may host one or more ANC functions. In some aspects, C-RU 404 may host core network functions locally. In some aspects, C-RU 404 may have a distributed deployment. Distributed units (DU) 406 may host one or more TRPs 308. DU 406 may be located at the edge of a network with radio frequency (RF) capabilities. In some aspects, network controller 130 may include C-CU 402.

[0056] As indicated above, Figure 4 This is provided merely as an example. Other examples are possible and may differ from the examples described above. Figure 4 as described.

[0057] Figure 5 is a diagram illustrating an example 500 of a network architecture for time-sensitive network traffic transmission via a wireless communication system in accordance with various aspects of the present disclosure.

[0058] Time-sensitive networking (TSN) services are a type of service associated with low latency and high reliability, defined by a set of Ethernet communication standards (e.g., as part of the Institute of Electrical and Electronics Engineers (IEEE) 802.1). These standards define mechanisms for synchronous, time-sensitive transmission of data over wired Ethernet networks, including a variety of parameters that can be configured to meet various latency requirements, reliability requirements, jitter requirements, etc. In some scenarios, the transmission of TSN services via wireless communication systems (such as, new radio (e.g., 5G) wireless communication systems) may require strict latency and / or reliability requirements in wireless communication scenarios, such as use cases such as industrial Internet of Things (IIoT) services, factory automation services, etc. provided by ultra-reliable low latency communication (URLLC) services. Some of the techniques and devices described herein help convert TSN service parameters into service parameters that can be used in wireless communication systems such as 5G systems, thereby allowing TSN services to be carried via wireless communication systems while meeting strict communication requirements.

[0059] like Figure 5 As shown in , TSN endpoints 510 can communicate with each other via wireless communication system 520 and / or TSN bridge 530. In some aspects, wireless communication system 520 can act as TSN bridge 530. Wireless communication system 520 can include network controller 130, which can receive TSN configuration information from a centralized network configuration (CNC) device in wired TSN. In some aspects, TSN endpoint 510 can include UE 120.

[0060] As an example, the first TSN endpoint 510 may include a device configured as a transmitter (e.g., referred to as a "talker" in TSN), and the second TSN endpoint 510 may include a device configured as a receiver (e.g., referred to as a "listener" in TSN). In some aspects, the talker may include a programmable logic controller (PLC), etc. Additionally or alternatively, the listener may include a sensor, an actuator, etc. (e.g., a robotic arm, a manufacturing device, an industrial robot, etc.). The talker may transmit TSN traffic to the listener using a TSN protocol (e.g., according to one or more TSN communication standards). TSN traffic may be assigned a traffic class (e.g., corresponding to one of eight Ethernet traffic classes of different priorities).

[0061] The wired TSN bridge 530 can process TSN services according to the service level and TSN service configuration, as shown below: Figure 6 Described in more detail. A TSN service configuration may be received from a CNC device in a wired TSN. Because the TSN service configuration is associated with a wired communication standard (e.g., Ethernet), parameters for processing TSN services, handling admission control (e.g., with certain guarantees or requirements, such as maximum latency, etc.), performing service scheduling (e.g., scheduling of data transmission), etc. may be specific to the wired communication standard, and these parameters may be different from the parameters used in the wireless communication system 520. When the wireless communication system 520 processes and / or carries TSN services, various wireless protocols, wireless communication standards, etc. may be used. Some of the techniques and devices described herein facilitate converting TSN service configurations intended for use in wired communication systems into parameters (e.g., stream bit rate, maximum data burst size, etc.) that can be used in the wireless communication system 520. In this way, requirements associated with TSN services may be used for admission control, scheduling, etc. in the wireless communication system 520.

[0062] In some aspects, the network controller 130 may perform some of the techniques described herein to help convert the TSN service configuration into parameters that can be used in a wireless communication system 520 (such as a 5G system). The network controller 130 may include, for example, one or more devices and / or functions of a core network of the wireless communication system 520. For example, the network controller 130 may include an access and mobility function (AMF), a session management function (SMF), a user plane function (UPF), a policy control function (PCF), etc. In addition or alternatively, the network controller 130 may be a separate entity in the core network (e.g., an adapter function that connects a wired TSN network to the wireless communication system 520), or may be part of an SMF, PCF, AMF, UPF, etc. As described in more detail below, the network controller 130 may transmit one or more parameters associated with the handling of TSN services to the base station 110 (e.g., which may act as a TSN bridge 530). The base station 110 may apply these parameters to perform operations associated with handling TSN services, such as admission control, scheduling, etc.

[0063] As indicated above, Figure 5 are provided as examples. Other examples are possible and may differ from those described herein. Figure 5 For example, in some aspects, the network architecture may not include a wired TSN bridge 530 .

[0064] Figure 6 is a schematic diagram illustrating an example 600 of a time-sensitive network traffic configuration according to various aspects of the present disclosure.

[0065] As shown in reference numeral 605, the TSN service configuration may indicate parameters associated with one or more TSN service levels (e.g., one of eight possible Ethernet levels), where different TSN service levels may be handled with different priorities. As shown in reference numeral 610, the TSN service configuration may indicate the duration of the service level associated with the gated open state, as indicated in the gated control list. The TSN bridge 530 (or a device such as the base station 110 that acts as the TSN bridge 530) may schedule and / or transmit TSN services of the service level during the period in which the service level is associated with the gated open state. In some aspects, the TSN service configuration may indicate the duration of the gated open state for multiple TSN service levels. Additionally or alternatively, as shown in reference numeral 615, the TSN service configuration may indicate the periodicity of the occurrence of such a gated open state (e.g., shown as a cycle time).

[0066] In example 600, the TSN service configuration indicates a gated open state of 75 microseconds (us) duration for service level 5, followed by a gated open state of 25 microseconds duration for service level 6, followed by a gated open state of 100 microseconds duration for all other service levels (e.g., service levels 0, 1, 2, 3, 4, and 7). The gated open state for service level 5 is indicated by an "o" in CCCCoCC (or, for example, 00000100 or 11111011), where each bit corresponds to a service level, and the value of the bit (e.g., 0 or 1) indicates whether the gating for the service level is open or closed, and the corresponding duration is 75 microseconds. Similarly, the gated open state for service level 6 is indicated by an "o" in CCCCCoC, with a corresponding duration of 75 microseconds, and the gated open states for the remaining service levels are indicated by the "o" entry in oooooCCo, with a corresponding duration of 100 microseconds. The period of the gate-open state is 200 microseconds, which means that a specific state is triggered every 200 microseconds, which is also equal to the sum of the duration of each gate-open state (for example, 25+75+100=200).

[0067] As shown at reference numeral 620, using this example TSN service configuration, a first gating cycle begins with a first time period in which TSN service level 5 is associated with a gated open state lasting 75 microseconds. During the first time period, the TSN bridge 530 and / or the base station 110 may transmit only TSN services of service level 5 and may not transmit any other TSN service levels (e.g., because the gating control list indicates that all other service levels except service level 5 are associated with a gated closed state during the first time period). Therefore, the TSN bridge 530 and / or the base station 110 may schedule only TSN services of service level 5 for transmission in the first time period.

[0068] As shown by reference numeral 625, after the first period expires (e.g., after 75 microseconds), a second period occurs in which TSN service level 6 is associated with a gated open state that lasts for 25 microseconds. During the second period, the TSN bridge 530 and / or the base station 110 may transmit only TSN services of service level 6 and may not transmit any other TSN service levels (e.g., because the gating control list indicates that all other service levels except service level 6 are associated with a gated closed state during the second period). Therefore, the TSN bridge 530 and / or the base station 110 may schedule only TSN services of service level 6 for transmission in the second period.

[0069] As shown by reference numeral 630, after the second period expires (e.g., after 25 microseconds), a third period occurs in which TSN service levels 0, 1, 2, 3, 4, and 7 are associated with a gated open state that lasts for 100 microseconds. During the third period, the TSN bridge 530 and / or the base station 110 may only transmit TSN services having one of these service levels, and may not transmit any other TSN service level (e.g., level 5 or level 6). Therefore, the TSN bridge 530 and / or the base station 110 may only schedule TSN services of service level 0, 1, 2, 3, 4, or 7 for transmission in the third period.

[0070] As shown by reference numeral 635, after the third period expires, a second gating cycle begins. The second gating cycle includes periods corresponding to the first period, the second period, and the third period described above. Thus, each of the first gating-on period for service level 5, the second gating-on period for service level 6, and the third gating-on period for the remaining service levels reoccurs with a periodicity indicated by the TSN service configuration (e.g., 200 microseconds in the example 600).

[0071] As indicated above, Figure 6 are provided as examples. Other examples are possible and may differ from those described herein. Figure 6 For example, the number of periods in the gated period, the duration of the period, the traffic level associated with the gated open period during the period, the periodicity, etc. may be different from the above combined Figure 6 as described.

[0072] Figure 7 is a diagram illustrating an example 700 of quality of service mapping for time sensitive network traffic in a wireless communication system in accordance with various aspects of the present disclosure.

[0073] As shown in reference numeral 710, a network controller 130 associated with a wireless communication system 520 (e.g., a 5G or new radio wireless communication system) may receive a TSN service configuration (also referred to as an IEEE 802.1Qbv configuration, etc.). In some aspects, the network controller 130 may receive the TSN service configuration from a device associated with the TSN (such as a TSN endpoint 510, a TSN bridge 530, a CNC, a device that receives user input to configure the TSN, etc.). Additionally or alternatively, the network controller 130 may generate the TSN service configuration based at least in part on one or more requirements associated with the TSN, the TSN endpoint 510, the TSN service to be carried via the TSN, etc. In some aspects, the network controller 130 may determine and / or receive a TSN service configuration associated with establishing a TSN service flow for communicating between the TSN endpoints 510. In some aspects, the network controller 130 may be collocated with another network device. For example, the network controller 130 may be collocated with the base station 110 or with a TSN configuration entity such as a CNC. In this case, the network controller 130 and the base station 110 may communicate with each other by providing information to each other.

[0074] As above combined Figure 6 As described, the TSN service configuration may indicate a duration of a gated open state (shown as "G", also referred to as a gated state octet) and a period (shown as "T", also referred to as a time interval) of a TSN service flow (e.g., having a particular service level) for a TSN service flow. In some aspects, the TSN service configuration may indicate multiple durations of multiple gated open states corresponding to different combinations of TSN service flows. For example, the TSN service configuration may indicate a gated open state with a duration of 75 microseconds for service level 5, followed by a gated open state with a duration of 25 microseconds for service level 6, followed by a gated open state with a duration of 100 microseconds for all other service levels (e.g., service levels 0, 1, 2, 3, 4, and 7), as described above in conjunction with FIG. Figure 6 described.

[0075] As indicated by reference numeral 720, the network controller 130 may determine one or more TSN capability parameters associated with the network controller 130. The TSN capability parameters may indicate capabilities associated with the network controller 130 and / or the wireless communication system 520 (e.g., one or more devices included in the wireless communication system 520) with which the network controller 130 operates related to the transmission of TSN traffic. In some aspects, the TSN capability parameters may depend on one or more capabilities of the wireless communication system. For example, different wireless communication systems using the network controller 130 may have different TSN capability parameters, depending on various parameters such as supported subcarrier spacing, bandwidth, backhaul quality, etc.

[0076] In some aspects, the TSN capability parameters may relate to delays associated with the transmission of TSN traffic. For example, the TSN capability parameters may relate to delays associated with the transmission of TSN traffic via the wireless communication system 520 with which the network controller 130 operates, such as a minimum delay for a frame (e.g., a packet, an Ethernet frame, an encapsulated Ethernet frame, etc.) to traverse the wireless communication system 520 (e.g., between TSN endpoints 510), a maximum delay for a frame to traverse the wireless communication system 520, etc.

[0077] In some aspects, the TSN capability parameters may include frame-dependent TSN capability parameters, which may depend on the size of the frame (e.g., frame size, packet size, etc.). For example, the frame-dependent TSN capability parameters may include a maximum dependent delay parameter (e.g., a maximum delay for a frame to traverse the wireless communication system 520, depending on the size of the frame, which may also be referred to as a dependentDelayMax parameter), a minimum dependent delay parameter (e.g., a minimum delay for a frame to traverse the wireless communication system 520, depending on the size of the frame, which may also be referred to as a dependentDelayMin parameter), a port transmission rate parameter (e.g., a rate at which one or more ports of one or more devices in the wireless communication system 520 can transmit frames, depending on the size of the frame, which may also be referred to as a portTransmitRate parameter), etc.

[0078] Additionally or alternatively, the TSN capability parameters may include frame-independent TSN capability parameters that may not depend on the size of the frame. For example, the frame-independent TSN capability parameters may include a maximum independent delay parameter (e.g., a maximum delay for a frame to traverse the wireless communication system 520 that is independent of the size of the frame, which may also be referred to as an independentDelayMax parameter), a minimum independent delay parameter (e.g., a minimum delay for a frame to traverse the wireless communication system 520 that is independent of the size of the frame, which may also be referred to as an independentDelayMin parameter), a transmission propagation delay parameter (e.g., a propagation delay associated with transmitting a frame (such as via air transmission) that is independent of the size of the frame, which may also be referred to as a txPropagationDelay parameter), etc.

[0079] As indicated by reference numeral 730, the network controller 130 may configure one or more QoS parameters associated with the wireless communication system 520 for a quality of service (QoS) flow to carry a TSN service flow (e.g., to carry a TSN service with a specific service level). The network controller 130 may configure the QoS parameters of the QoS flow based at least in part on a TSN capability parameter (e.g., as described above), a duration of a gated open state associated with the TSN service flow to be carried via the QoS flow, and / or a periodicity indicated by the TSN service configuration. As shown, the QoS parameters may include a maximum data burst volume (MDBV) parameter, a guaranteed flow bit rate (GFBR) parameter, a maximum flow bit rate (MFBR) parameter, a 5G QoS indicator (5QI) parameter, and the like. In some aspects, the parameters determined by the network controller 130 may facilitate the configuration and / or transmission of the TSN service flow and may therefore be referred to as time-sensitive communication assistance information (TSCAI). An example of TSCAI may refer to 3GPP Technical Specification (TS) 23.501 (such as Section 5.27.2 and Section 5.27.3 of Version 16.2.0).

[0080] As shown in reference numeral 740, in some aspects, the network controller 130 may configure the QoS parameters of the QoS flow for carrying the TSN service flow based at least in part on a frame-dependent TSN capability parameter (shown as "c") and at least one of a duration (shown as "G") or a periodicity (shown as "T") of a gated open state for the TSN service flow. For example, the MDBV parameter may be configured based at least in part on the frame-dependent TSN capability parameter and the duration (e.g., MDBV=c×G). Additionally or alternatively, the GFBR parameter may be configured based at least in part on the frame-dependent TSN capability parameter, the duration, and the periodicity (e.g., GFBR=c×G / T). Additionally or alternatively, the MFBR parameter may be configured based at least in part on the frame-dependent TSN capability parameter, the duration, and the periodicity (e.g., MFBR=c×G / T). In some aspects, "c" may be set equal to a value of 1 / dependentDelayMax, a value of 1 / dependentDelayMin, a value of portTransmitRate, etc. In some aspects, the MDBV parameter, GFBR parameter, and / or MFBR parameter may be based at least in part on the TSCAI.The TSCAI may be determined in a similar manner as described above based at least in part on the duration of the gated open state, one or more TSN capability parameters, and / or periodicity.

[0081] Additionally or optionally, the 5QI parameters may be configured based at least in part on frame-dependent TSN capability parameters, duration and / or periodicity. For example, the 5QI parameters may be configured as a function of a frame-dependent TSN capability parameter and at least one of a duration or periodicity (e.g., shown as 5QI=f(c, G and / or T)). In some aspects, the 5QI parameters may be determined by calculating one or more other QoS parameters (e.g., MDBV, GFBR, MFBR, etc.) and determining a standardized or pre-specified 5QI parameter having a corresponding QoS parameter that is closest to the calculated QoS parameter (e.g., the value is closest, the value is closest and greater than, the value is closest and less than, etc.). In this way, the calculated QoS parameters may be mapped to corresponding 5QI parameters that allow the QoS parameters to be met. In some aspects, the 5QI parameters may be determined based at least in part on the TSCAI.

[0082] As shown in reference numeral 750, in some aspects, the network controller 130 may configure the QoS parameters of the QoS flow for carrying the TSN service flow based at least in part on a frame-dependent TSN capability parameter (shown as "c"), a frame-independent TSN capability parameter (shown as "k"), and at least one of a duration (shown as "G") or a periodicity (shown as "T") of a gated open state of the TSN service flow. For example, the MDBV parameter may be configured based at least in part on the frame-dependent TSN capability parameter, the frame-independent TSN capability parameter, and the duration (e.g., MDBV=c×(Gk)). Additionally or alternatively, the GFBR parameter may be configured based at least in part on the frame-dependent TSN capability parameter, the frame-independent TSN capability parameter, the duration, and the periodicity (e.g., GFBR=c×(Gk) / T). Additionally or alternatively, the MFBR parameter may be configured based at least in part on the frame-dependent TSN capability parameter, the frame-independent TSN capability parameter, the duration, and the periodicity (e.g., MFBR=c×(Gk) / T). In some aspects, "k" may be set equal to a value of independentDelayMax, a value of independentDelayMin, a value of txPropagationDelay, etc. In some aspects, an MDBV parameter, a GFBR parameter, and / or a MFBR parameter may be determined based at least in part on the TSCAI. The TSCAI may be determined in a similar manner as described above based at least in part on a duration of a gated open state, one or more TSN capability parameters, and / or periodicity.

[0083] Additionally or optionally, the 5QI parameters may be configured at least in part based on a frame-dependent TSN capability parameter, a frame-independent TSN capability parameter, a duration and / or a period. For example, the 5QI parameters may be configured as a function of at least one of a frame-dependent TSN capability parameter, a frame-independent TSN capability parameter, and a duration or periodicity (e.g., shown as 5QI=f(c, k, G and / or T)). In some aspects, the 5QI parameters may be determined by calculating one or more other QoS parameters (e.g., MDBV, GFBR, MFBR, etc.) and determining a standardized or pre-specified 5QI parameter, which has a corresponding QoS parameter that is closest to the calculated QoS parameter (e.g., the value is closest, the value is closest and greater than, the value is closest and less than, etc.). In this way, the calculated QoS parameters may be mapped to corresponding 5QI parameters that allow the QoS parameters to be met. In some aspects, the 5QI parameters may be determined at least in part based on the TSCAI.

[0084] As shown in reference numeral 750, in some aspects, the network controller 130 can configure QoS parameters for a QoS flow carrying a TSN service flow based at least in part on a frame-dependent TSN capability parameter (shown as "c"), a frame-independent TSN capability parameter (shown as "k"), and at least one of a duration (shown as "G") or a periodicity (shown as "T") of a gated open state of the TSN service flow.

[0085] As shown in reference numeral 760, the network controller 130 may transmit one or more QoS parameters for a QoS service flow to a base station 110 associated with the wireless communication system 520, such as a base station 110 having a coverage area that includes one or more TSN endpoints 510 communicating using a TSN service flow. In some aspects, the network controller 130 may transmit one or more QoS parameters to the base station 110 before establishing a QoS flow to carry TSN services. Additionally or alternatively, the base station 110 and / or the network controller 130 may use the QoS parameters to perform admission control on TSN services. In some aspects, the network controller 130 may be collocated with another network device. For example, the network controller 130 may be collocated with the base station 110 or with a TSN configuration entity such as a CNC. In this case, the network controller 130 and the base station 110 may communicate with each other by providing information to each other.

[0086] For example, the base station 110 and / or the network controller 130 may determine whether the QoS parameters can be met (e.g., based at least in part on the traffic load, the number of UEs 120 and / or TSN endpoints 510, network conditions associated with the base station 110, the wireless communication system 520, etc.). If the QoS parameters can be met, the base station 110 and / or the network controller 130 may establish a QoS flow (and / or a radio bearer) to carry the TSN service according to the QoS parameters. If the QoS parameters cannot be met, the base station 110 and / or the network controller 130 may not establish a QoS flow (and / or a radio bearer) to carry the TSN service according to the QoS parameters. In this way, when the TSN service is carried through the wireless communication system 520 such as a 5G network, the quality of service of the TSN service can be guaranteed.

[0087] As indicated by reference numeral 770, the base station 110 may process the TSN service flow based at least in part on one or more QoS parameters. For example, as described above, the base station 110 may use one or more QoS parameters to perform admission control associated with the TSN service flow. Additionally or alternatively, the base station 110 may schedule the transmission of the TSN service of the TSN service flow via the QoS flow based at least in part on one or more QoS parameters. For example, the base station 110 may schedule (and / or transmit) the TSN service so that the QoS parameters are met. In this way, when the TSN service is carried by a wireless communication system 520 such as a 5G network, the quality of service of the TSN service can be guaranteed. In addition, various aspects of the wireless communication system 520 may be improved, such as the reliability of the wireless communication system 520 (e.g., by allowing the guarantee of latency and / or reliability requirements), the flexibility of the wireless communication system 520 (e.g., by allowing the carrying of TSN services), the efficiency of the wireless communication system 520 (e.g., due to the standardized conversion of TSN service configuration to QoS parameters), etc.

[0088] As indicated above, Figure 7 are provided as examples. Other examples are possible and may differ from those described above. Figure 7 as described.

[0089] Figure 8 is a diagram illustrating an example process 800 performed, for example, by a network controller, in accordance with various aspects of the present disclosure. Example process 800 is an example of a network controller (eg, network controller 130, etc.) performing operations associated with quality of service mapping for time-sensitive network traffic in a wireless communication system.

[0090] like Figure 8As shown in , in some aspects, process 800 may include receiving a traffic configuration for a time-sensitive network (TSN) indicating a duration of a gated open state for a TSN traffic flow and a periodicity at which the gated open state occurs (block 810). For example, as described above, a network controller (e.g., using controller / processor 290, memory 292, communication unit 294, etc.) may receive a TSN traffic configuration indicating a duration of a gated open state for a TSN traffic flow and a periodicity at which the gated open state occurs.

[0091] like Figure 8 As shown in , in some aspects, the process 800 may include: configuring one or more QoS parameters associated with a wireless communication system for a quality of service (QoS) flow to carry a TSN traffic flow, wherein the one or more QoS parameters are configured based at least in part on one or more TSN capability parameter configurations associated with a network controller and at least one of a duration or periodicity of a gated open state (block 820). For example, as described above, the network controller (e.g., using the controller / processor 290, the memory 292, the communication unit 294, etc.) may configure one or more QoS parameters associated with a wireless communication system associated with the network controller for a QoS flow to carry a TSN traffic flow. In some aspects, the one or more QoS parameters are configured based at least in part on one or more TSN capability parameters associated with the network controller and at least one of a duration or periodicity of a gated open state.

[0092] like Figure 8 As shown in , in some aspects, process 800 may include transmitting one or more QoS parameters to a base station of the wireless communication system (block 830). For example, as described above, a network controller (e.g., using controller / processor 290, memory 292, communication unit 294, etc.) may transmit one or more QoS parameters to a base station of the wireless communication system.

[0093] Process 800 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0094] In a first aspect, one or more QoS parameters are used for admission control or scheduling of QoS flows.

[0095] In a second aspect, either alone or in combination with the first aspect, the one or more QoS parameters include at least one of: a maximum data burst volume (MDBV) parameter, a guaranteed flow bit rate (GFBR) parameter, a maximum flow bit rate (MFBR) parameter, a 5G QoS indicator (5QI) parameter, or a combination thereof.

[0096] In a third aspect, alone or in combination with one or more of the first and second aspects, the MDBV parameters are configured based at least in part on at least one of a duration of a gated open state or one or more TSN capability parameters.

[0097] In a fourth aspect, either alone or in combination with one or more of the first to third aspects, the MDBV parameters are determined based at least in part on time-sensitive communication assistance information (TSCAI), and wherein the TSCAI is determined at least in part based on the duration of a gated open state or at least one of one or more TSN functional parameters.

[0098] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, at least one of the GFBR parameters or the MFBR parameters is configured based at least in part on a duration, a periodicity, and one or more TSN capability parameters of a gated open state.

[0099] In a sixth aspect, alone or in combination with one or more of the first to fifth aspects, 5QI parameters are configured based at least in part on a duration, a periodicity, and one or more TSN capability parameters of a gated open state.

[0100] In the seventh aspect, alone or in combination with one or more of the first to sixth aspects, the one or more TSN capability parameters include at least one of the following: a maximum dependent delay parameter, a minimum dependent delay parameter, a port transfer rate parameter, a maximum independent delay parameter, a minimum independent delay parameter, a transmission propagation delay parameter, or a combination of the above.

[0101] In an eighth aspect, alone or in combination with one or more of the first to seventh aspects, the one or more TSN capability parameters include a first TSN capability parameter related to dependent delay and a second TSN capability parameter related to independent delay.
