[0026] In a first aspect, embodiments of this disclosure propose an information processing method, executed by a base station, comprising: receiving first information, wherein the first information includes at least one of the following: first time information, the first time information being used to indicate the transmission delay of uplink data from the base station to the core network device; second time information, the second time information being used to indicate the delay of the core network device in processing uplink data; third time information, the third time information being used to indicate the delay of the core network device in processing downlink data; and fourth time information, the fourth time information being used to indicate the time when downlink data is sent from the core network device.

[0027] In the above embodiments, the base station can be aware of the uplink transmission delay of uplink data from the base station to the core network, the delay of the core network equipment in processing uplink data and / or the delay of the core network in processing data, and / or the time when downlink data is sent from the core network equipment, so as to know the downlink transmission delay of downlink data from the core network equipment to the base station; thus, it is easier for the base station to perform better scheduling at the air interface to meet the latency requirements.

[0028] In conjunction with some embodiments of the first aspect, in some embodiments, receiving first information includes at least one of the following: receiving downlink data, wherein the packet header of the downlink data includes at least one of the following: a first field and a second field; the first field is used to indicate first time information, and the second field is used to indicate fourth time information; receiving first control signaling, wherein the first control signaling includes at least one of the following: first time information, second time information, third time information, and fourth time information.

[0029] In the above embodiments, the first information can be received in multiple ways, thus adapting to more application scenarios. Furthermore, if the first information is transmitted in downlink data, it can be transmitted without additional signaling, saving signaling overhead.

[0030] In conjunction with some embodiments of the first aspect, in some embodiments, before receiving the first information, the method further includes: sending second information, wherein the second information includes at least one of the following: fifth time information, which is used to indicate the time when the base station receives uplink data; sixth time information, which is used to indicate the time when the base station sends uplink data; and seventh time information, which is used to indicate the delay in the base station processing uplink data.

[0031] In the above embodiments, the core network equipment can know the time when the base station receives uplink data and the time when the base station sends uplink data, thereby enabling the core network equipment to know the time when the base station processes uplink data; and if the base station determines the time when it processes uplink data and informs the core network equipment, the core network equipment does not need to calculate the time when it processes uplink data, thereby reducing the burden on the core network equipment.

[0032] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: sending an eighth time information, the eighth time information being used to indicate the delay in the base station processing downlink data.

[0038] In the above embodiments, the base station can accurately obtain the downlink transmission delay between the core network equipment and the base station, which facilitates better scheduling of the base station at the air interface to meet the latency requirements.

[0039] In conjunction with some embodiments of the first aspect, in some embodiments, the ninth time information is determined based on the fourth time information and the time of receiving the downlink data, including one of the following: if there is one downlink data, the ninth time information is determined based on the fourth time information of the one downlink data and the time of receiving the one downlink data; if there are multiple downlink data, the ninth time information of each downlink data is determined based on the fourth time information of each downlink data and the time of each downlink data; or the ninth time information of multiple downlink data is determined based on the average value of the ninth time information of each downlink data.

[0040] In the above embodiments, when there are multiple downlink data, the downlink transmission delay of the multiple downlink data (i.e., the ninth time information) can be calculated based on the average downlink transmission delay of each downlink data, thereby obtaining a relatively accurate downlink transmission delay of the downlink data, which facilitates better scheduling of the base station in the air interface.

In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0100] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0101] In some embodiments, the core network device 103 may be a single device, multiple devices, or a group of devices. The core network includes, for example, at least one of the following: Evolved Packet Core (EPC), 5G Core Network (5GCN), Next Generation Core (NGC), and 6G Core Network (6GCN).

[0102] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions provided in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in this disclosure are also applicable to similar technical problems.

[0103] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1A, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1A are illustrative. The communication system may include all or some of the main bodies in FIG1A, or it may include other main bodies outside of FIG1A. The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0104] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G New Radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future generation Radio Access (FX), Global System for Mobile Communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0105] In some embodiments, the Packet Delay Budget (PDB) defines the upper limit of packet delay between the UE and the N6 termination point on the User Plane Function (UPF). The N6 interface is the interface between the UPF and the Data Network (DN). The PDB applies to downlink (DL) packets received by the UPF through the N6 interface and uplink (UL) packets transmitted by the UE. For a given 5G QoS Identifier (5QI), the PDB value is the same in both the UL and DL.

[0106] Optionally, the PDB can be used to support the configuration of scheduling and link layer functions (e.g., scheduling priority weights and the configuration of Hybrid Automatic Repeat reQuest (HARQ) target operation points). For Guaranteed Bit Rate (GBR) QoS flows using delay-critical resource types, packets with delays exceeding the PDB are considered lost if the data burst does not exceed the default Maximum Data Burst Volume (MDBV) within the PDB period and the QoS flow does not exceed the Guaranteed Flow Bit Rate (GFBR). For GBR QoS flows with GBR resource types not exceeding GFBR, 98% of packets will not experience delays exceeding 5QI of the PDB. The 5G access network packet delay budget (e.g., 5G-AN PDB) is determined by subtracting a static value of the core network packet delay budget (CN PDB), which represents the delay between any N6 termination point at the UPF (for any UPF that may be selected for a PDU session) and the 5G-AN from a given PDB.

[0107] In some embodiments, an example of a data transmission path in a wireless network may be shown in Figure 1B. A terminal (e.g., a UE) sends uplink data to a peer communication entity and receives downlink data from the peer communication entity via an access network device (e.g., a base station), a core network device (e.g., a UPF), and a data network. The terminal indicates time-related information about the data packets to the access network device, allowing the access network device to know the latency of the data packets over the air interface. However, the latency information from the base station to the core network device is currently unknown.

[0108] Currently, access network devices (such as base stations) can obtain some latency information, but this latency information only reflects service characteristics statistically analyzed by the core network, such as the service arrival cycle, arrival time, and arrival latency jitter statistics. It does not address the transmission latency between access network devices and core network devices. If the uplink and downlink latency information of base stations and core network devices during transmission, as well as the data processing latency of the core network devices, could be known, scheduling at the air interface could be better performed to meet latency requirements.

[0109] In some embodiments, the UE can be a terminal, or the terminal can be a UE.

[0176] In some embodiments, the base station receives fourth information sent by the core network device; if the fourth information instructs the base station to provide second information, the base station sends second information to the core network device.

[0177] Step S2104: The core network device determines the first time information based on the sixth time information and the time when the uplink data was received.

[0178] Optionally, the first-time information is used to indicate the transmission delay of uplink data from the base station to the core network equipment.

[0179] Optionally, the time indicated by the first time information is a relative time. For example, the time indicated by the first time information could be 2 minutes.

[0180] Optionally, the first-time information is used by the core network equipment to send to the base station.

[0181] Optionally, the name of the first-time information is not limited, and it may be, for example, the first time, the first delay, the uplink transmission delay information, or the uplink delay information, etc.

[0182] Optionally, the core network device determines the time indicated by the first time information based on the difference between the time when the uplink data is received and the time indicated by the sixth time information. For example, if the time indicated by the sixth time information is T2 (e.g., 11:11), and the time when the core network device receives the uplink data is T4 (e.g., 11:13), then the time indicated by the first time information can be T5 = T4 - T2 (e.g., 11:13 minus 11:11, which is 2 minutes).

[0183] In some embodiments, determining the first time information based on the sixth time information and the time of receiving the uplink data may include: if there is only one uplink data, determining the first time information based on the sixth time information of the one uplink data and the time of receiving the one uplink data. Thus, when there is only one uplink data, the difference between the time of receiving the uplink data and the time indicated by the sixth time information can be calculated to determine the time indicated by the first time information.

[0184] In some embodiments, determining the first time information based on the sixth time information and the time of receiving the uplink data may include: if there are multiple uplink data, determining the first time information of each uplink data based on the sixth time information of each uplink data and the time of receiving each uplink data; and determining the first time information of the multiple uplink data based on the average value of the first time information of each uplink data.

[0185] For example, when there are multiple uplink data, such as the first uplink data, the second uplink data, and the third uplink data; the time indicated by the sixth time information of the first uplink data and the time of receiving the first uplink data are T21 and T41, respectively; the time indicated by the sixth time information of the second uplink data and the time of receiving the second uplink data are T22 and T42, respectively; the time indicated by the sixth time information of the third uplink data and the time of receiving the third uplink data are T23 and T43, respectively; then the first time information of the first uplink data is T51 = T41 - T21, the first time information of the second uplink data is T52 = T42 - T22, and the first time information of the third uplink data is T53 = T43 - T23; the first time information of these three uplink data can be T5 = (T51 + T52 + T53) / 3.

[0186] Thus, when there are multiple uplink data, the first time information of each uplink data can be obtained, and based on the average of the first time information of each uplink data, the first time information of multiple uplink data (i.e., uplink transmission delay information) can be obtained.

[0187] In some embodiments, the core network device may determine the first-time information based on the Quality of Service Flow ID (QFI). Here, the QoS Flow ID is used to identify a QoS Flow; determining that the first-time information is based on the QoS Flow ID may mean that the determination of the first-time information is based on statistics of uplink data of a QoS Flow.

[0188] In some alternative embodiments, the core network device determines the seventh time information based on the fifth and sixth time information.

[0189] Optionally, the core network equipment determines the time of the seventh time information indication based on the difference between the time indicated by the sixth time information indication and the time indicated by the fifth time information indication. In this way, the core network equipment can determine the latency for the base station to process uplink data.

Alternatively, the fifth indication information is used to indicate that the core network equipment supports providing the first information; the sixth indication information is used to indicate that the core network equipment does not support providing the first information.

[0199] Optionally, a predetermined field of the sixth information can be used to indicate that the core network device supports the ability to provide the first information; the predetermined field can be any field of the sixth information; the predetermined field can be one or more bits. For example, when the predetermined field of the sixth information is a first value, it is used to indicate that the core network device supports the ability to provide the first information; or, when the predetermined field of the sixth information is a second value, it is used to indicate that the core network device does not support the ability to provide the first information. For example, when the predetermined field of the sixth information is a first value, it is used to indicate that the core network device supports the provision of the first information; or, when the predetermined field of the sixth information is a second value, it is used to indicate that the core network device does not support the provision of the first information.

[0200] Optionally, the sixth information is for one of the following: each terminal, each session, and each QoS flow.

[0201] For example, the sixth information is specific to each terminal. Here, for all sessions of a terminal, the core network device's ability to provide the first information is the same; for different terminals, the core network device's ability to provide the first information may be the same or different.

[0202] For example, the sixth information is per session. Here, the ability of the core network device to provide the first information is the same for all QoS flows of a session; for different sessions, the ability of the core network device to provide the first information may be the same or different.

[0203] For example, the sixth information is for each QoS flow. Here, the core network device's ability to provide the first information may be the same or different for different QoS flows.

[0207] Optionally, the third time information is used to indicate the latency of core network equipment in processing downlink data.

[0208] Optionally, the fourth time information is used to indicate the time when downlink data is sent from the core network equipment.

[0209] For example, and / or, the time indicated by the second time information is a relative time; and / or, the time indicated by the third time information is a relative time; and the time indicated by the fourth time information is an absolute time. For instance, the time indicated by the second time information could be 3 minutes, etc.; the time indicated by the third time information could be 3 minutes, etc.; and the time indicated by the fourth time information could be 11:18, etc.

[0210] Optionally, the names of the second time information, the third time information, and the fourth time information are not limited; for example, the second time information, the third time information, and the fourth time information can be the second time, the third time, and the fourth time, respectively; or, the second time information, the third time information, and the fourth time information can be the second delay, the third delay, and the fourth delay, respectively.

[0212] Step S2106: The base station sends third information to the core network equipment.

[0213] In some embodiments, the core network equipment receives third information sent by the base station.

[0214] Optionally, the third information is used to indicate whether the core network equipment provides the first information. In this way, the base station can configure the core network equipment to provide the first information.

[0215] Optionally, the third information is used to instruct the core network device to provide the first information, or the third information is used to instruct the core network device not to provide the first information.

[0216] Optionally, the third information includes a seventh instruction information and an eighth instruction information; the seventh instruction information is used to instruct the core network equipment to provide the first information, or the eighth instruction information is used to instruct the core network equipment not to provide the first information.

[0217] Optionally, a predetermined field of the third information can be used to indicate whether the core network device provides the first information; the predetermined field can be any field of the third information; the predetermined field can be one or more bits. For example, when the predetermined field of the third information is a first value, it is used to indicate that the core network device provides the first information; or, when the predetermined field of the third information is a second value, it is used to indicate that the core network device does not provide the first information.

[0218] Optionally, the third information is for one of the following: each terminal, each session, and each QoS flow.

[0219] For example, the third information is specific to each terminal. Here, for all sessions of a terminal, the base station configures or instructs the core network equipment to provide the first information, or the base station configures or instructs the core network equipment not to provide the first information; for different terminals, whether the base station configures or instructs the core network equipment to provide the first information may be the same or different.

[0220] For example, the third information is per session. Here, for all QoS flows of a session, the base station configures or instructs the core network device to provide the first information, or the base station configures or instructs the core network device not to provide the first information; or, for different sessions, the base station configuration instructs the core network device to provide the same or different first information.

[0221] For example, the third information is specific to each QoS flow. Here, for different QoS flows, the base station configuration or instruction to the core network equipment to provide the first information may be the same or different.

[0222] Optionally, the name of the third information is not limited, and it may be, for example, configuration instruction information or base station configuration information.

[0223] In step S2107, the core network equipment sends the first information to the base station.

[0224] In some embodiments, the base station receives first information sent by the core network equipment.

[0225] In some embodiments, the core network device sends downlink data to the base station, wherein the packet header of the downlink data includes at least one of the following: a first field and a second field; the first field is used to indicate first time information, and the second field is used to indicate fourth time information.

[0226] In some embodiments, the base station receives downlink data sent by the core network equipment, wherein the packet header of the downlink data includes at least one of the following: a first field and a second field; the first field is used to indicate first time information, and the second field is used to indicate fourth time information.

[0227] Optionally, downlink data can be packaged into one or more data packets; wherein each data packet may include a header; the header may include at least one field. For example, the data packet header includes a first field and a second field; the first field is used to indicate first time information or the time indicated by the first time information; the second field is used to indicate fourth time information or the time indicated by the fourth time information.

[0228] Optionally, the packet header may also include at least one of the following: a seventh field and an eighth field; the seventh field is used to indicate the second time information or to carry the time indicated by the second time information; the eighth field is used to indicate the third time information or to carry the time indicated by the third time information.

[0229] Optionally, the first, second, seventh, and eighth fields can all be any field in the packet header, a reserved field, or an extended field. For example, the downlink data packet can be a GTP-U packet; the first, second, seventh, and eighth fields can each be an extended field in the header of that GTP-U packet.

[0230] Optionally, the core network equipment sends the first information to the base station for QFI. That is, the core network equipment determines the first time information, second time information, third time information, and / or fourth time information at the granularity of each QoS flow. For example, if there are multiple data packets for uplink data in a QoS flow, the average transmission delay of these multiple data packets from the base station to the core network equipment is determined as the time indicated by the first time information of these multiple data packets.

[0231] In some embodiments, the core network device sends a first control signaling to the base station, wherein the first control signaling includes at least one of the following: first time information, second time information, third time information, and fourth time information.

[0232] In some embodiments, the base station receives a first control signaling sent by the core network equipment, wherein the first control signaling includes at least one of the following: first time information, second time information, third time information, and fourth time information.

[0233] Optionally, there may be one or more first control signaling messages. A first control signaling message includes at least a portion of the first information.

[0234] Optionally, the first control signaling can be any control signaling. For example, the first control signaling can be RRC signaling or Downlink Control Information (DCI), etc.

[0235] In some embodiments, the core network device sends first information to the base station if it supports the ability to provide first information.

[0236] In some embodiments, the core network device receives third information sent by the base station; and when the third information instructs the core network device to provide first information, it sends first information to the base station.

[0237] In step S2108, the base station determines the ninth time information based on the fourth time information and the time when the downlink data is received.

[0238] Optionally, the ninth time information is used to indicate the transmission delay of downlink data from the core network equipment to the base station.

[0239] Optionally, the time indicated by the ninth time information is a relative time. For example, the time indicated by the ninth time information could be 2 minutes.

[0240] Optionally, the name of the ninth time information is not limited, and it may be, for example, the ninth time, the ninth delay, the downlink transmission delay information, or the downlink delay information, etc.

[0241] In some embodiments, the base station determines the time of the ninth time information indication based on the difference between the time when the downlink data is received and the time indicated by the fourth time information. For example, if the time indicated by the fourth time information is T6 (e.g., 11:18), and the time when the base station receives the downlink data is T7 (e.g., 11:20), then the time indicated by the ninth time information is T8 = T6 - T7 (e.g., 11:20 minus 11:18, which can be 2 minutes).

[0242] In some embodiments, determining the ninth time information based on the fourth time information and the time of receiving downlink data may include: if there is only one downlink data, determining the ninth time information based on the fourth time information of the one downlink data and the time of receiving the downlink data. Thus, when there is only one downlink data, the difference between the time of receiving the downlink data and the time indicated by the fourth time information can be calculated to determine the time indicated by the ninth time information.

[0243] In some embodiments, determining the ninth time information based on the fourth time information and the time of receiving the downlink data may include: if there are multiple downlink data, determining the ninth time information of each downlink data based on the fourth time information of each downlink data and the time of receiving each downlink data; and determining the ninth time information of the multiple downlink data based on the average value of the ninth time information of each downlink data.

[0244] For example, when there are multiple downlink data, such as the first downlink data, the second downlink data, and the third downlink data; the time indicated by the fourth time information of the first downlink data and the time of receiving the first downlink data are T61 and T71, respectively; the time indicated by the fourth time information of the second downlink data and the time of receiving the second downlink data are T62 and T72, respectively; the time indicated by the fourth time information of the third downlink data and the time of receiving the third downlink data are T63 and T63, respectively; then the ninth time information of the first downlink data is T81 = T71 - T61, the ninth time information of the second downlink data is T82 = T72 - T62, and the ninth time information of the third downlink data is T83 = T73 - T63; the ninth time information of these three downlink data can be T8 = (T81 + T82 + T83) / 3.

[0245] Thus, when there are multiple downlink data, the ninth time information of each downlink data can be obtained, and based on the average of the ninth time information of each downlink data, the ninth time information (i.e., downlink transmission delay information) of multiple downlink data can be obtained.

[0246] In some embodiments, the base station determines that the ninth time information may be specific to the QoS Flow ID. Here, the QoS Flow ID is used to identify the QoS Flow; determining that the ninth time information is specific to the QoS Flow ID may mean that the ninth time information is statistically analyzed for uplink data of a QoS Flow.

[0294] This disclosure provides an information processing method, the method comprising:

[0295] In some embodiments, the base station sends data packets to the core network equipment with time-related information.

[0296] Optionally, the core network equipment can be a control plane network element, such as an AMF, or a user plane processing network element, such as a UPF.

[0297] Optionally, the time-related information of the data packet includes at least one of the following:

[0298] The time point at which the base station receives the uplink data (e.g., T1);

[0299] The time point at which the base station receives and processes the uplink data and sends the data to the core network (e.g., T2) (T2-T1 represents the processing delay of the base station for the uplink data packet);

[0300] The processing latency of downlink data by the base station, such as the latency of rendering operations.

[0301] In some embodiments, the base station device indicates time-related information of the data packets in the header of the uplink data packets (e.g., the GTP-U Extension Header) or in the control signaling sent by the base station to the core network device.

[0302] Optionally, time-related information can be absolute time information; for example, time-related information can be indicated using GPS time or UTC, such as hours, minutes, seconds, or milliseconds.

[0303] Optionally, time-related information can be relative time information; for example, time-related information can be how much time has elapsed.

[0304] In some embodiments, the core network device determines the transmission delay information from the base station to the core network by indicating time-related information of the data packets in the header of the uplink data packets (e.g., the extended header of GTP-U).

[0305] Optionally, the core network device obtains the uplink transmission delay information (e.g., T5) from the time the data was sent by the base station (e.g., T2) to the time the core network device receives it from the GTP-U packet header. In this way, the core network device can obtain the delay information for each data packet, providing more granular information.

[0306] In some embodiments, the core network device obtains the processing latency of the base station for uplink and / or downlink data from the control signaling sent by the base station. This processing latency can be a statistical assessment by the base station based on data packets over a period of time. Relatively speaking, it is quite static.

[0307] In some embodiments, in the downlink direction, the core network device determines the uplink transmission delay information from the base station to the core network based on the time-related information of the data packets indicated by the base station; and notifies the base station via user plane signaling. Here, the base station can comprehensively evaluate the overall end-to-end delay and the transmission delay from the base station to the core network device to obtain a better scheduling strategy. For example, if the base station knows that the transmission delay from the base station to the core network device is large, it will speed up the scheduling of air interface data packets during uplink scheduling.

[0308] Optionally, in the downlink direction, the core network equipment determines the uplink transmission delay information from the base station to the core network by indicating time-related information in the header of the uplink data packet (e.g., the extended header of GTP-U) by the base station equipment; and notifies the base station via user plane signaling. Here, the core network equipment carries this time-related information in the downlink GTP-U header.

[0309] Optionally, in the downlink direction, the core network equipment obtains uplink transmission delay information from the base station to the core network by having the base station equipment indicate time-related information in the header of the uplink data packet (e.g., the extended header of GTP-U); and notifies the base station via control plane signaling. Here, the core network equipment carries this time-related information in the downlink GTP-U header. This could be a statistical result of multiple data packets, such as averaging the delays obtained from multiple data packets.

[0310] Optionally, the core network equipment can indicate the time-related information of the data packet corresponding to the QFI, that is, the core network equipment notifies the base station at the QFI granularity.

[0311] In some embodiments, in the downlink direction, in addition to providing the base station with transmission delay information from the base station to the core network, the core network device may also provide the processing delay of uplink data packets and / or downlink data packets of the core network device.

[0312] Optionally, the core network equipment can also provide downlink latency information (such as the fourth time information in the previous embodiment) to the base station to facilitate the base station's assessment of the transmission latency information from the core network to the base station (such as the ninth time information in the previous embodiment).

[0313] Optionally, the core network device indicates the time point when the data is sent from the core network in the GTP-U packet header (e.g., T6). If the base station receives the data packet at the time of (e.g., T7), it obtains the downlink transmission delay information of the data from the core network to the base station (e.g., T8).

[0314] In some embodiments, the base station can configure whether the core network can provide latency information, or the core network can notify the base station whether to provide latency information.

[0315] Optionally, latency information can be configured at the PDN session granularity, the QoS flow granularity, or the terminal granularity.

[0316] In some embodiments, the base station may notify the core network whether it supports the ability to provide latency information, or the core network may notify the base station whether it supports the ability to provide latency information.
