Description

Technical Field

[0001] Various embodiments are directed to devices, methods, apparatus, and computer-readable media for radio resource reservation. Background Art

[0002] Radio resource reservation can be applied to the time-sensitive communication (TSC) service of the new radio (NR) system defined by the third generation partnership project (3GPP) standard 23.501 to ensure quality of service (QoS) and reduce signaling overhead. TSC auxiliary information (TSCAI) includes periodic and burst arrival time (BAT) parameters, which can be used for radio resource reservation in the radio access network (RAN). For the case of the fifth generation system (5GS) time-sensitive network (TSN) bridge, TSCAIBAT derivation can currently be performed when the TSN bridge supports per-stream filtering and supervision (PSFP). However, the support of PSFP is optional, which means that BAT will not be provided to the RAN without PSFP support. TSCAIBAT is also an optional parameter for Internet Protocol (IP) type TSC services (referred to as generic TSC in the rest of this application) that do not rely on the TSN standard defined by the Institute of Electrical and Electronics Engineers (IEEE). Therefore, it is difficult for the RAN to easily calculate the appropriate value of the configuration grant (CG) or semi-persistent scheduling (SPS), thereby failing to provide periodic TSC services with delay constraints. Furthermore, due to the large signaling overhead and the existence of additional scheduling delays, for TSC services (eg, uplink (UL) TSC services), relying on a dynamic scheduling mechanism is not preferred.

[0115] Hereinafter, some example embodiments will be described in detail with reference to the accompanying drawings. The following description includes specific details for the purpose of providing a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts can be practiced without these specific details. In some cases, well-known circuits, techniques, and components are shown in block diagram form to avoid obscuring the concepts and features described.

[0116] The example embodiments of the present application provide a solution for radio resource reservation. According to the example embodiments of the present application, suitable values ​​of local downlink (DL) and / or uplink (UL) BAT can be estimated for the RAN to reserve radio resources. Alternatively or additionally, according to the example embodiments of the present application, for incoming TSC services, the initial value of the local BAT can be correctly determined, and for ongoing TSC services, the value of the local BAT can be correctly and dynamically updated, thereby guaranteeing TSC services during their life cycle. The example embodiments of the present application can be applied to both TSN bridges and general TSCs.

[0117] Figure 1 Scenarios in which various example embodiments of the present application may be implemented are briefly illustrated.

[0118] according to Figure 1, network device 110 and network 120 are shown as examples of entities acting as at least one base station, such as a next generation node B (gNB), or an evolved node B (eNB), or a centralized unit (CU), or a distributed unit (DU), or a combination of a CU and a DU in a RAN. A network controller 130 is shown as an example of an entity controlling at least one base station. Network devices 110 and 120 may represent any network device in a RAN controlled by network controller 130. Network controller 130 may be located in another network device acting as a BS. Alternatively, network controller 130 may be located in network device 110 and network device 120. For example, if network controller 130 is located in network device 110, network controller 130 may be located in and act as a CU of a BS, and network device 110 may act as a DU of a BS. A core network control plane (CN-CP) 150 is shown as an example of an entity or network function of a core network (CN) associated with a RAN.

[0119] Figure 1 The scenario shown can be applied to the Open RAN (O-RAN) architecture. O-RAN is an operator-led alliance that brings openness and programmability to RAN. The RAN Intelligent Controller (RIC) is a new virtualized function that adds RAN programmability to existing or new RAN networks. A near real-time RIC (Near-RT RIC) can be connected to one or more "E2 nodes" via an E2 interface, which can support near real-time (e.g. 10-100ms) data exchange between the Near-RT RIC and the E2 nodes. The E2 node here is a logical node that terminates the E2 interface, which can be at least one of the following: gNB, eNB, CU, DU, or a combination of CU and DU. In conjunction with Figure 1 In a related example embodiment, the network controller 130 may be a Near-RT RIC, the network device 110 and / or the network device 120 may be an E2 node, and the network controller 130 may communicate with the network device 110 and / or the network device 120 via an E2 interface in the O-RAN architecture.

[0120] The network controller 130 may subscribe to the network devices 110 and 120 for incoming Next Generation Application Protocol (NGAP) request reports for packet data unit (PDU) session establishment or modification requests containing TSC information that may correspond to, for example, a TSC QoS flow. Such NGAP requests may be referred to as TSC-related events, which may correspond to, for example, a TSC QoS flow.

[0121] Taking the network device 120 as an example, when the CN-CP 150 provides the network device 120 with a TSCAI 152 that does not include a BAT parameter for an incoming TSC-related event (e.g., an incoming TSC service) and an indication that the application function (AF) supports burst timing adaptation capability, the network device 120 can report the incoming TSC-related event 122 to the network controller 130.

[0122] In response to the incoming report of the TSC-related event 122, the network controller 130 may determine an initial value 134 for the local BAT, determine a radio resource reservation instruction 132 based on the initial value 134 of the local BAT, and transmit the determined radio resource reservation instruction 132 including the local BAT initial value 134 to the network device 120, so that the network device 120 may configure radio resources according to the radio resource reservation instruction 132. The network device 120 may also transmit the initial value 134 of the local BAT to the CN-CP 150.

[0123] Whether the TSCAI 152 provided by the CN-CP 150 includes the initial value 134 of the local BAT, or the network controller 130 determines the initial value 134 of the local BAT, the network controller 130 may update the value of the local BAT during the TSC service lifecycle. For example, the network device 120 may subscribe to a report of TSC-related event monitoring results from the network device 120. The network device 120 may perform TSC-related event monitoring and report the TSC-related event monitoring results to the network controller 130, so that the network controller 130 may update the value of the local BAT and the radio resource reservation instruction.

[0124] Figure 2 An example sequence diagram of radio resource reservation according to some example embodiments of the present application is shown. Figure 2 , the network device 210 may be the network device 110 or the network device 120 and may act as any BS in the RAN, such as a gNB, and the network controller 260 may be the network controller 130 and may control one or more network devices including the network device 210.

[0125] and Figure 2 Related example embodiments may be applied to an O-RAN architecture, where the network controller 260 may be a Near-RT (near real-time) RIC and may communicate with a BS (e.g., gNB) such as a network device 210 through an E2 interface in the O-RAN architecture. The network device 210 may be, for example, an E2 node, which may be at least one of the following: a gNB, an eNB, a CU, a DU, or a combination of a CU and a DU.

[0126] In operation 212, a PDU session is established. In addition to the network device 210 and the network controller 260, other devices not shown, such as terminal devices (such as user equipment (UE) and / or device-side TSN converter (DS-TT)), core network functions (such as 5GC network functions, such as access and mobility management function (AMF), session management function (SMF), user plane function (UPF), policy control function (PCF)), TSN AF in the case of TSN bridge (such as 5GS bridge), and / or TSC and time synchronization function (TSCTSF) in the case of general TSC, etc., may be involved in the PDU session establishment and subsequent PDU session modification process.

[0127] The network controller 260 may subscribe to RAN status and RAN performance information from network devices controlled by the network controller 260. Thus, a controlled network device, such as the network device 210, may report RAN status 214 and / or RAN performance information 216 to the network controller 260. The reporting of the RAN status 214 and / or RAN performance information 216 may be triggered by an event or periodically. The RAN performance information 216 may include instantaneous RAN performance information of the network device 210. The RAN status 214 and / or RAN performance information 216 may include, for example, at least one of the following factors of the network device 210: cell load, inter-cell interference, available resources, mobility data of one or more terminal devices, ongoing and incoming service demands, or any other factor that may affect the resource configuration of the network device 210.

[0128] In one embodiment, network controller 260 may subscribe to reports of incoming TSC-related events from one or more network devices controlled by network controller 260. For example, network controller 260 may transmit a subscription 262 for incoming TSC-related event reports to network device 210. In one embodiment, the incoming TSC-related events may correspond to a TSC QoS flow.

[0129] On the other hand, in the case of a TSN bridge, a centralized network configuration (CNC) can perform TSN flow scheduling and provide bridging configuration information to TSNAF.

[0130] Then, during operation 220 of the PDU session modification, the TSN AF in the case of a TSN bridge, or the TSC TSF in the case of a generic TSC, may provide a TSC auxiliary container (TSCAC) to the SMF via the PCF. The SMF may then construct a TSCAI for the incoming TSC related events based on the received TSCAC. If the BAT parameters are missing in the TSCAC, the TSCAI will also have no BAT parameters. The TSCAC may be transmitted together with an indication that the TSN AF or the TSC TSF supports the burst timing adaptation capability. And the SMF may transmit the TSCAI without the BAT parameters and the indication of the burst timing adaptation capability to the network device controlled by the network controller 260.

[0131] The burst timing adaptation capability may be, for example, defined in 3GPP Technical Report 23.700-25, solution #13, and may be used by a CN-CP (eg, CN-CP 150 ) to request RAN BAT preference information.

[0132] Upon receiving the TSCAI from the SMF, if the network device 210 detects that the TSCAI does not include the BAT parameters, the network device 210 may transmit a report 222 of an incoming TSC-related event to the network controller 260 .

[0133] In one embodiment, the report 222 of the incoming TSC-related event may include at least one of the following: a PDU session identifier (ID), a quality of service flow identifier (QFI), a TSCAI, or one or more QoS parameters. The PDU session ID may indicate a specific PDU session of the network controller 260. The QFI may indicate a specific QoS flow of the network controller 260, so that the network controller 260 can be aware of, for example, a specific event. The TSCAI may be the TSCAI received from the SMF. The one or more QoS parameters may relate to QoS requirements for a specific TSC QoS flow, such as priority level, CN packet delay budget (PDB), guaranteed flow bit rate (GFBR), maximum data burst size (MDBV), packet error rate (PER), etc.

[0134] Upon receiving the incoming report 222 of the time-sensitive communication-related event from the network device 210, the network controller 260 may determine an initial value 226 of the local BAT in response to the report 222 in operation 264. In one embodiment, the network controller 260 may determine the initial value 226 of the local BAT based on at least one of the incoming report 222 of the TSC-related event corresponding to, for example, a TSC QoS flow, the RAN state 214, or the RAN performance information 216.

[0135] The network controller 260 may act as a central coordinator of the TSC. Based on the above-mentioned relevant factors that may affect resource configuration, the network controller 260 may determine a suitable initial value 226 for TSC services (e.g., CG and / or SPS) through, for example, artificial intelligence (AI) and / or machine learning (ML) methods. In the case where the incoming TSC-related event corresponds to a TSC QoS flow, the initial value 226 of the local BAT may be used for the establishment of the TSC QoS flow.

[0136] Then, in operation 266, the network controller 260 may determine a radio resource reservation instruction 268 based on the initial value 226 of the local BAT. The radio resource reservation instruction 268 may include the initial value 226 of the local BAT. In one embodiment, the determined radio resource reservation instruction 268 may also include one or more cross-layer resource configuration parameters, such as a bandwidth part (BWP) for resource reservation, a K repetition value for medium access control (MAC) layer hybrid automatic repeat request (HARQ) transmission, a packet data convergence protocol (PDCP) duplication parameter, and a layer 1 (L1) frequency hopping mode, etc.

[0137] The network controller 260 may then transmit the determined radio resource reservation instruction 268 including at least the initial value 226 of the local BAT to the network device 210. In one embodiment, the determined radio resource reservation instruction 268 including the initial value 226 of the local BAT may be transmitted via an E2 interface in an O-RAN architecture, which may support near real-time data exchange between the network controller 260 and the network device 210.

[0138] After receiving the radio resource reservation instruction 268 including the local BAT initial value 226 from the network controller 260 , in operation 224 , the network device 210 may configure radio resources according to the determined radio resource reservation instruction 268 .

[0139] After successfully reserving radio resources, the network device 210 may transmit the initial value 226 of the local BAT to the CN. For example, the network device 210 may forward the initial value 226 of the local BAT to the CN-CP 150 as RAN BAT preference information. In one embodiment, the SMF may convert the local BAT initial value 226 in the 5GS clock to the TSCAC BAT in the TSN clock based on the clock drift learned through the input of the UPF. The SMF transmits the converted TSCAC BAT to the TSN AF (in the case of a TSN bridge) or the TSC TSF (in the case of a universal TSC) through the PCF.

[0140] TSN AF or TSCTSF can derive the recommended transmit offset parameters of the source station, thereby affecting the transmit behavior of the source station to maximize the use of the TSC function of 5GS.

[0141] In the above exemplary embodiment, the CN does not provide the value of the local BAT to the network device 210, and the network controller 260 determines and provides the initial value 226 of the local BAT to the network device 210. Alternatively or additionally, in some embodiments, the initial value 226 of the local BAT may also be provided by the CN. Regardless of whether the initial value 226 of the local BAT is provided by the CN or determined by the network controller 260, according to the exemplary embodiment of the present application, the network controller 260 may update the value of the local BAT during the life cycle of the TSC service.

[0142] In one embodiment, the network controller 260 may subscribe to the network device 210 for a report of a TSC-related event monitoring result corresponding to a TSC QoS flow. For example, the network controller 260 may transmit a subscription 270 to the network device 210 for a TSC-related event monitoring result report. In one embodiment, the subscription 270 may indicate at least one monitoring parameter for the network device 210 to perform TSC-related event monitoring, such as measurement and reporting. In the case where the TSC-related event corresponds to a TSC QoS flow, the monitoring parameter may be, for example, QoS monitoring defined in 3GPP standard TS23.502. The subscription 270 may also indicate the QoS parameters to be measured, the reporting frequency, and the threshold of the network device 210. The QoS parameters to be measured may indicate UL packet delay, DL packet delay, or both. The reporting frequency may indicate the frequency of the report, such as the time interval between two consecutive reports. The threshold may be used as follows: if the TSC-related event monitoring result measured on the TSC-related event exceeds the threshold, the network device 210 will report the TSC-related event monitoring result. In addition, the subscription 270 may also indicate the measurement frequency and the threshold.

[0143] After receiving a subscription request 270 for a TSC-related event monitoring result report corresponding to a TSC QoS flow from the network controller 260, the network device 210 may perform TSC-related event monitoring in operation 228. For example, in the case where at least one monitoring parameter indicated in the subscription 270 is for the RAN portion of uplink / downlink packet delay, the network device 210 may perform a measurement of the RAN portion of the UL / DL packet delay. If, for example, the measured RAN portion of the UL / DL packet delay exceeds a threshold, the network device 210 may report the measured RAN portion of the UL / DL packet delay to the network controller 260 as a TSC-related event monitoring result. For example, the network device 210 may transmit a report 230 of the TSC-related event monitoring result to the network controller 260.

[0144] In operation 272, the network controller 260 may update the value of the local BAT in response to the report 230 of the TSC-related event monitoring result. In one embodiment, the updating of the local BAT value may include: calculating the local burst arrival time value based on at least one of the following: the reported TSC-related event monitoring result, the RAN state 214, the data buffer length, the received downlink data packet survival time (age), the received uplink data packet access request survival time, or the RAN performance information 216, for example, by an AI and / or ML method. Therefore, the updated value 234 of the local BAT may be calculated. The RAN state 214 and / or the RAN performance information 216 used in operation 272 may be different from those used in operation 264, because the RAN state 214 and / or the RAN performance information 216 may be updated after operation 264.

[0145] Then, in operation 274, the network controller 260 may update the radio resource reservation instruction based on the updated value 234 of the local BAT. The updated radio resource reservation instruction 276 may include at least the updated value 234 of the local BAT.

[0146] In one embodiment, the updated radio resource reservation instruction 276 may further include at least one of the following: a distribution time range of the local BAT value or one or more cross-layer resource configuration parameters.

[0147] The distribution time range of the local BAT value may be predicted by the network controller 260. For example, if the TSC-related event corresponds to a TSC QoS flow, the network controller 260 may predict the distribution time range of the local BAT value based on the reported TSC QoS flow monitoring results.

[0148] One or more cross-layer resource configuration parameters may be different from those in the radio resource reservation instruction 268, for example including at least one of the following: the number of CG / SPS configurations covering the local BAT value distribution time range, the K repetition value of MAC layer HARQ transmission for accelerated scheduling, PDCP replication parameters, L1 frequency hopping mode, or dual / multi-connection activation / release indication.

[0149] The network controller 260 may then transmit an updated radio resource reservation instruction 276 including at least the local BAT update value 234 to the network device 210. In one embodiment, the updated radio resource reservation instruction 276 including the local BAT update value 234 may be transmitted via an E2 interface in an O-RAN architecture, which may support near real-time data exchange between the network controller 260 and the network device 210.

[0150] After receiving the updated radio resource reservation instruction 276 including the local BAT update value 234 from the network controller 260 , the network device 210 may reconfigure radio resources according to the updated radio resource reservation instruction 276 in operation 232 .

[0151] Similar to transmitting the initial value 226 of the local BAT to the core network, upon successfully reserving radio resources according to the updated radio resource reservation instruction 276, the network device 210 may transmit an updated value 234 of the local BAT to the CN.

[0152] It will be appreciated that the updated value 234 of the local BAT and / or the updated radio resource reservation instruction 276 may be further updated in a manner similar to the manner in which the updated value 234 of the local BAT and / or the updated radio resource reservation instruction 276 are obtained.

[0153] In one embodiment, the network controller 260 may be, for example, a Near-RT RIC. In one embodiment, the Near-RT RIC may not be deployed, and / or the network device (such as the network device 210) may not support the E2 interface or the appropriate E2 service model (E2SM) (e.g., for the O-RAN architecture) in the O-RAN architecture, in which case the network controller 260 (e.g., the Near-RT RIC) may be located within a network device such as the network device 210. In one embodiment, the network controller 260 may be located within another network device that acts as a base station different from the network device 210. Alternatively, the network controller 260 may be located within the network device 210, in which case the network controller 260 may be located and operate as a CU of the BS, and the network device 210 may act as a DU of the base station.

[0154] The example embodiments of the present application allow the RAN to estimate the appropriate value of the local BAT when the BAT parameter does not exist in the TSCAI provided by the core network through the NGAP interface, thereby realizing an efficient and effective radio resource reservation mechanism in the RAN in this case. The example embodiments of the present application can handle the coordination of multiple TSC services because the network controller (e.g., Near-RT RIC) has relevant information of multiple RAN BSs. Combined with the computing power of algorithms (including AI / ML algorithms), the network controller can act as a central coordinator for ongoing TSC services, incoming TSC services, and non-TSC services. Therefore, the example embodiments of the present application can determine more efficient radio resource reservations for TSC-related events and reduce radio resource reservation failures. In addition, according to the example embodiments of the present application, it is feasible to use BAT preferences to adjust application transmission scheduling to meet limited latency requirements.
