[0033] 1, a schematic diagram of a wireless communication system provided by an embodiment of the present disclosure is shown. As shown in FIG. 1, the wireless communication system is a communication system based on mobile communication technology and may include multiple user equipments 110 and multiple base stations 120.

[0034] Here, the user equipment 110 may be a device that provides a user with a voice connection and / or a data connection. The user equipment 110 can communicate with one or more core networks via a Radio Access Network (RAN). The user equipment 110 may be a sensor device, an Internet of Things user equipment such as a mobile phone, or a computer with Internet of Things user equipment, and may be, for example, a fixed, portable, pocket-sized, handheld, computer-integrated, or vehicle-mounted device. For example, the user equipment 110 may be a station (STA), subscriber unit, subscriber station, mobile station, mobile, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment.

[0035] The base station 120 may be a network-side device in a wireless communication system. Here, the wireless communication system may be the 4th generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system, or the wireless communication system may be a 5G system, also known as a new air interface system or a 5G NR system. Alternatively, the wireless communication system may be a next-generation system of a 5G system. Among these, an access network in a 5G system may also be referred to as a New Generation-Radio Access Network (NG-RAN).

[0036] The base station 120 may be an evolved base station (eNB) used in a 4G system. Alternatively, the base station 120 may be a base station (gNB) employing a centralized-distributed architecture in a 5G system.

[0039] Here, the above user equipment can be considered as a terminal device in the following embodiments.

[0040] In some embodiments, the wireless communication system may also include a network management device 130 .

[0041] A plurality of base stations 120 are respectively connected to the network management device 130. The network management device 130 may be a core network device in a wireless communication system. For example, the network management device 130 may be a mobility management entity (MME) in an evolved packet core network (EPC). Alternatively, the network management device may be another core network device, such as a serving gateway (SGW), a public data network gateway (PGW), a policy and charging rules function (PCRF), or a home subscriber server (HSS). The embodiments of the present disclosure do not limit the implementation form of the network management device 130.

[0042] In order to facilitate the understanding of those skilled in the art, the embodiments of the present disclosure will enumerate several embodiments to clearly explain the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art can understand that the several embodiments provided by the embodiments of the present disclosure can be implemented alone, or can be implemented in combination with the methods of other embodiments in the embodiments of the present disclosure, or can be implemented in combination with some methods of other related technologies. The embodiments of the present disclosure are not limited thereto.

[0043] As shown in FIG. 2 , this embodiment provides a method for reporting a BSR, where the method is performed by a terminal, and includes:

[0044] Step 21: Send a Buffer Status Report (BSR) containing the assistance information to the access network device.

[0045] Here, the assistance information is used to assist the access network device to perform data scheduling for a given service.

[0046] In one embodiment, the assistance information is used to indicate the urgency of scheduling data of the predetermined service. In one embodiment, the assistance information is used to indicate at least delay budget information for scheduling data of the predetermined service. The delay budget information may be time length information, such as 1 ms.

[0047] Here, the terminal according to the present disclosure may be, but is not limited to, a mobile phone, a wearable device, an in-vehicle terminal, a roadside unit (RSU), a smart home terminal, an industrial sensing device, and / or a medical device, etc. In some embodiments, the terminal may be a Redcap terminal or a new air interface NR terminal of a predetermined version (e.g., an R17 NR terminal).

[0048] The access network device according to the present disclosure may be a base station, which may be of various types, such as a base station of a third generation mobile communication (3G) network, a base station of a fourth generation mobile communication (4G) network, a base station of a fifth generation mobile communication (5G) network, or other evolved base stations.

[0049] In one embodiment, the support information comprises: High urgency level, Medium urgency level, and Indicates one of the lower urgency levels.

[0050] For example, "index0" indicates a high level of urgency, "index1" indicates a medium level of urgency, and "index2" indicates a low level of urgency. Note that if the support information indicates null, it can be determined that the level of urgency is low.

[0051] In one embodiment, the aiding information is used to indicate delay budget information for scheduling data for a given service.

[0052] In one embodiment, delay budget information can be quantified and reported, where a mapping relationship between identifiers and durations can be established, where different identifiers can indicate different durations.

[0053] For example, index "index0" may indicate that the delay budget is within range 1 (e.g., 0 to 10 milliseconds), index "index1" may indicate that the delay budget is within range 2 (e.g., 10 to 20 milliseconds), and index "index2" may indicate that the delay budget is within range 3 (e.g., 20 to 30 milliseconds).

[0054] That this index or codepoint corresponds to a particular delay budget information can be signaled in advance by the network or agreed upon through a protocol.

[0055] In one embodiment, the urgency of scheduling data is determined based on a delay requirement for transmitting data of a predetermined service. Illustratively, in response to the delay requirement for transmitting data of the predetermined service being smaller than a delay threshold, the urgency of scheduling the data is determined to be greater than a reference urgency level, or in response to the delay requirement for transmitting data of the predetermined service being larger than a delay threshold, the urgency of scheduling the data is determined to be less than a reference urgency level.

[0056] In one embodiment, the access stratum of the terminal can obtain the assistance information from the non-access stratum or the service stratum.

[0057] In one embodiment, the terminal determines the aiding information based on the implementation.

[0058] In one embodiment, the assistance information is obtained, and the assistance information is used to indicate at least the urgency of scheduling data for a given service, and a buffer status report (BSR) including the assistance information is sent to the access network device.

[0059] In one embodiment, the method obtains the aiding information, which is used to indicate at least the urgency of scheduling multiple QoS data streams of the XR service, and transmits a buffer status report (BSR) including the aiding information to the access network device.

[0060] In one embodiment, the method obtains the assistance information, and the assistance information is used to indicate the urgency of scheduling different data in at least one QoS data stream of the XR service. The method also includes transmitting a Buffer Status Report (BSR) including the assistance information to the access network device.

[0061] In one embodiment, the assistance information is obtained, and the assistance information is used to indicate at least the urgency of scheduling different data in the same logical channel of the XR service. A buffer status report (BSR) including the assistance information is sent to the access network device.

[0062] In one embodiment, a buffer status report (BSR) including aiding information is transmitted to an access network device, the aiding information being used to indicate at least a degree of urgency for scheduling data of a given service, and the aiding information being used by the network to determine a scheduling priority for scheduling the data of the given service, where the higher the scheduling priority of the data, the more preferentially the data is scheduled. The scheduling priority may be positively related to the urgency, such that the higher the urgency, the higher the scheduling priority.

[0063] In one embodiment, the assistance information is carried through a predetermined information field of the MAC control element (CE) that transmits the BSR. For example, referring to FIG. 3, the information field for transmitting the BSR in the related art includes one extension field, i.e., a scheduling index. N is added to indicate information such as the urgency or delay budget for scheduling data for a given service. Here, N is an integer equal to or greater than 1. Note that the Scheduling Index corresponding to different N values N may be associated with different logical channel groups (LCGs), and different LCGs may be indicated by different identifiers ID, such as LCG ID1 and LCG ID2.

[0064] In one embodiment, the assistance information is associated with a predetermined logical channel identifier LCID. In one embodiment, an extended logical channel identifier LCID can be added to indicate an extended BSR report (i.e., the BSR includes the assistance information). For example, a reserved LCID can be used to indicate an extended BSR report.

[0065] In one embodiment, the terminal receives configuration information sent by the access network device, the configuration information being used to instruct the terminal to report the BSR, and sends a buffer status report (BSR) including assistance information to the access network device, the assistance information being used to indicate at least information such as urgency or delay budget for scheduling data of a predetermined service.

[0066] In one embodiment, the terminal receives configuration information transmitted by the access network device, and the configuration information is used to instruct the terminal to report the BSR with terminal granularity, the terminal to report the BSR with logical channel group (LCG) granularity, or the terminal to report the BSR with logical channel granularity. A buffer status report (BSR) including assistance information is transmitted to the access network device, and the assistance information is used to indicate at least information such as the urgency or delay budget for scheduling data of a predetermined service.

[0067] In addition, in a scenario where the terminal is reported at a granularity level, if the base station determines that the terminal is a terminal that executes the XR service, the terminal must report the BSR using an extended BSR report format, i.e., the BSR must include the support information.

[0068] In a scenario where logical channel group (LCG) reporting is performed as granularity, if the base station determines that the terminal is a terminal that performs XR service, the base station notifies the terminal that the extended BSR report format must be used for the specific LCG, and that the terminal can continue to use the pre-extension BSR report format for LCGs other than the specific LCG. The extended BSR report format includes the support information in the BSR. In one embodiment, when configuring a logical channel group, the base station can configure the BSR report on this LCG to use the extended BSR report.

[0069] In addition, in a scenario in which the BSR is reported at the granularity of a logical channel, if the base station determines that the terminal is a terminal that executes an XR service, it notifies the terminal that an extended BSR report format needs to be used for a specific logical channel.

[0070] In one embodiment, the BSR is sent to the access network device based on a reporting scheme using LCG as granularity, and the assistance information is used to indicate at least information such as the urgency or delay budget for scheduling data for a given service.

[0071] In addition, when a base station sets up a logical channel, if it sets up the BSR report on this logical channel to use the extended BSR report, the BSR report on the LCG to which the logical channel belongs will use the extended BSR report.

[0072] In one embodiment, when a BSR report is based on an LCG report, any logical channel configured to use extended BSR reporting causes the BSR report to use extended BSR reporting on the LCG.

[0073] In one embodiment, when a BSR report is based on an LCG report, all logical channels configured to use extended BSR reporting will have the BSR report use extended BSR reporting on the LCG.

[0074] In one embodiment, the BSR is transmitted to the access network device based on a reporting scheme using a single logical channel as granularity, and the assistance information is used to indicate at least information such as the urgency or delay budget for scheduling data for a given service.

[0075] In one embodiment, when the base station configures a logical channel, it configures the BSR report on this logical channel to use the extended BSR report, in which case the report on the logical channel uses the extended BSR report.

[0076] In one embodiment, the method includes transmitting reference information to an access network device, the reference information indicating whether the terminal supports or does not support the ability to report the BSR and / or the reference information indicating whether the terminal is expected or not to report the BSR; receiving configuration information transmitted by the access network device, the configuration information being used to instruct the terminal to report the BSR; and transmitting a buffer status report (BSR) to the access network device, the BSR including assistance information, the assistance information being used to indicate at least the urgency of scheduling data for a predetermined service.

[0077] In an embodiment of the present disclosure, a buffer status report (BSR) including assistance information is transmitted to an access network device, and the assistance information is used to assist the access network device in performing data scheduling for a predetermined service. Here, the BSR includes assistance information indicating an urgency of scheduling data for the predetermined service. After receiving the BSR, the access network device can schedule data for the predetermined service based on the urgency of scheduling data for the predetermined service indicated by the assistance information, which assists the access network device in performing data scheduling for the predetermined service. Compared with a method in which the access network device arbitrarily schedules data for the predetermined service, the access network device can prioritize scheduling of data with high urgency for the predetermined service based on the assistance information, thereby enabling reliable decoding of data with high urgency and improving reliability of data transmission.

[0078] It should be noted that those skilled in the art can understand that the methods provided in the embodiments of the present disclosure can be performed alone or in combination with some methods in the embodiments of the present disclosure or some methods in the related art.

[0079] As shown in FIG. 4 , this embodiment provides a method for reporting a BSR, where the method is performed by a terminal, and includes:

[0080] Step 41: Receive configuration information sent by an access network device.

[0081] Here, the configuration information is used to instruct the terminal to report the BSR.

[0082] In one embodiment, the method includes receiving configuration information sent by an access network device, the configuration information being used to instruct the terminal to report the BSR, and sending a buffer status report (BSR) including assistance information to the access network device, the assistance information being used to indicate at least information such as urgency or delay budget for scheduling data for a predetermined service.

[0083] In one embodiment, the terminal receives configuration information sent by an access network device, and the configuration information is used to instruct the terminal to report the BSR with terminal granularity, the terminal to report the BSR with logical channel group (LCG) granularity, or the terminal to report the BSR with logical channel granularity. A buffer status report (BSR) including assistance information is sent to the access network device, and the assistance information is used to indicate at least information such as the urgency or delay budget for scheduling data of a predetermined service.

[0084] In addition, in a scenario where the terminal is reported at a granularity level, if the base station determines that the terminal is a terminal that executes the XR service, the terminal must report the BSR using an extended BSR report format, i.e., the BSR must include the support information.

[0085] In a scenario where logical channel group (LCG) reporting is performed as granularity, if the base station determines that the terminal is a terminal that performs XR service, the base station notifies the terminal that the extended BSR report format must be used for the specific LCG, and that the terminal can continue to use the pre-extension BSR report format for LCGs other than the specific LCG. The extended BSR report format includes the support information in the BSR. In one embodiment, when configuring a logical channel group, the base station can configure the BSR report on this LCG to use the extended BSR report.

[0086] In addition, in a scenario in which the BSR is reported at the granularity of a logical channel, if the base station determines that the terminal is a terminal that executes an XR service, it notifies the terminal that an extended BSR report format needs to be used for a specific logical channel.

[0087] It should be noted that those skilled in the art can understand that the methods provided in the embodiments of the present disclosure can be performed alone or in combination with some methods in the embodiments of the present disclosure or some methods in the related art.

[0088] As shown in FIG. 5 , this embodiment provides a method for reporting a BSR, where the method is performed by a terminal, and includes:

[0089] Step 51: Send the reference information to the access network device.

[0090] Here, the reference information indicates whether the terminal supports or does not support the capability to report the BSR, and / or the reference information indicates whether the terminal is expected to report the BSR or not.

[0091] In one embodiment, reference information is sent to an access network device, the reference information indicating whether the terminal supports or does not support the ability to report the BSR and / or the reference information indicates whether the terminal is expected or not to report the BSR. Configuration information sent by the access network device is received, the configuration information is used to instruct the terminal to report the BSR. A buffer status report (BSR) including assistance information is sent to the access network device, the assistance information is used to indicate at least information such as the urgency or delay budget for scheduling data for a predetermined service.

[0092] It should be noted that those skilled in the art can understand that the methods provided in the embodiments of the present disclosure can be performed alone or in combination with some methods in the embodiments of the present disclosure or some methods in the related art.

[0093] As shown in FIG. 6 , this embodiment provides a method for reporting a BSR, where the method is performed by an access network device, and includes:

[0094] Step 61: Receive a Buffer Status Report (BSR) containing assistance information sent by a terminal.

[0095] Here, the assistance information is used to assist the access network device to perform data scheduling for a given service.

[0096] In one embodiment, the assistance information is used to indicate at least the urgency of scheduling data for a given service.

[0097] In one embodiment, the assistance information is used to indicate at least a delay budget for scheduling data of a given service, which may be a time duration such as 1 ms.

[0098] Here, the terminal according to the present disclosure may be, but is not limited to, a mobile phone, a wearable device, an in-vehicle terminal, a roadside unit (RSU), a smart home terminal, an industrial sensing device, and / or a medical device, etc. In some embodiments, the terminal may be a Redcap terminal or a new air interface NR terminal of a predetermined version (e.g., an R17 NR terminal).

[0099] The access network device according to the present disclosure may be a base station, which may be of various types, such as a base station of a third generation mobile communication (3G) network, a base station of a fourth generation mobile communication (4G) network, a base station of a fifth generation mobile communication (5G) network, or other evolved base stations.

[0100] In one embodiment, the support information comprises: High urgency level, Medium urgency level, and Indicates one of the lower urgency levels.

[0101] For example, "index0" indicates a high level of urgency, "index1" indicates a medium level of urgency, and "index2" indicates a low level of urgency. Note that if the support information indicates null, it can be determined that the level of urgency is low.

[0102] In one embodiment, the aiding information is used to indicate delay budget information for scheduling data for a given service.

[0103] In one embodiment, delay budget information can be quantified and reported, where a mapping relationship between identifiers and durations can be established, where different identifiers can indicate different durations.

[0104] For example, index "index0" may indicate that the delay budget is within range 1 (e.g., 0 to 10 milliseconds), index "index1" may indicate that the delay budget is within range 2 (e.g., 10 to 20 milliseconds), and index "index2" may indicate that the delay budget is within range 3 (e.g., 20 to 30 milliseconds).

[0105] That this index or codepoint corresponds to a particular delay budget information can be signaled in advance by the network or agreed upon through a protocol.

[0106] In one embodiment, the urgency of scheduling data is determined based on a delay requirement for transmitting data of a predetermined service. Illustratively, in response to the delay requirement for transmitting data of the predetermined service being smaller than a delay threshold, the urgency of scheduling the data is determined to be greater than a reference urgency level, or in response to the delay requirement for transmitting data of the predetermined service being larger than a delay threshold, the urgency of scheduling the data is determined to be less than a reference urgency level.

[0107] In one embodiment, the access stratum of the terminal can obtain the assistance information from the non-access stratum or the service stratum.

[0108] In one embodiment, the terminal determines the aiding information based on the implementation.

[0109] In one embodiment, a buffer status report (BSR) including assistance information sent by a terminal is received, and the assistance information is used to indicate at least the urgency of scheduling multiple QoS data streams of the XR service.

[0110] In one embodiment, a buffer status report (BSR) including assistance information sent by a terminal is received, and the assistance information is used to indicate at least the urgency of scheduling different data within one QoS data stream of an XR service.

[0111] In one embodiment, a buffer status report (BSR) including assistance information sent by a terminal is received, and the assistance information is used to indicate at least the urgency of scheduling different data in the same logical channel of an XR service.

[0112] In one embodiment, a buffer status report (BSR) including assistance information transmitted by a terminal is received, the assistance information being used to indicate at least an urgency of scheduling data of a predetermined service, and a scheduling priority for scheduling the data of the predetermined service is determined based on the assistance information. The higher the scheduling priority of data, the higher the scheduling priority of the data. The scheduling priority may be positively related to the urgency, such that the higher the urgency, the higher the scheduling priority.

[0113] In one embodiment, the assistance information is carried through a predetermined information field of the MAC control element (CE) that transmits the BSR. For example, referring again to FIG. 3, the information field for transmitting the BSR in the related art includes one extension field, i.e., a scheduling index. N is added to indicate information such as the urgency or delay budget for scheduling data for a given service. Here, N is an integer equal to or greater than 1. Note that the Scheduling Index corresponding to different N values N may be associated with different logical channel groups (LCGs), and different LCGs may be indicated by different identifiers ID, such as LCG ID1 and LCG ID2.

[0114] In one embodiment, the assistance information is associated with a predetermined logical channel identifier LCID. In one embodiment, an extended logical channel identifier LCID can be added to indicate an extended BSR report (i.e., the BSR includes the assistance information). For example, a reserved LCID can be used to indicate an extended BSR report.

[0115] In one embodiment, the configuration information is sent to a terminal, where the configuration information is used to instruct the terminal to report the BSR. A buffer status report (BSR) including assistance information is sent to an access network device, where the assistance information is used to indicate at least urgency or delay budget information for scheduling data of a predetermined service.

[0116] In one embodiment, the configuration information is sent to a terminal, and the configuration information is used to instruct the terminal to report the BSR with terminal granularity, the terminal to report the BSR with logical channel group (LCG) granularity, or the terminal to report the BSR with logical channel granularity. A buffer status report (BSR) including assistance information is sent to an access network device, and the assistance information is used to indicate at least urgency or delay budget information for scheduling data of a predetermined service.

[0117] In addition, in a scenario where the terminal is reported at a granularity level, if the base station determines that the terminal is a terminal that executes the XR service, the terminal must report the BSR using an extended BSR report format, i.e., the BSR must include the support information.

[0118] In a scenario where logical channel group (LCG) reporting is performed as granularity, if the base station determines that the terminal is a terminal that performs XR service, the base station notifies the terminal that the extended BSR report format must be used for the specific LCG, and that the terminal can continue to use the pre-extension BSR report format for LCGs other than the specific LCG. The extended BSR report format includes the support information in the BSR. In one embodiment, when configuring a logical channel group, the base station can configure the BSR report on this LCG to use the extended BSR report.

[0119] In addition, in a scenario in which the BSR is reported at the granularity of a logical channel, if the base station determines that the terminal is a terminal that executes an XR service, it notifies the terminal that an extended BSR report format needs to be used for a specific logical channel.

[0120] In one embodiment, the terminal receives the BSR transmitted based on a reporting scheme using LCG as granularity, and the assistance information is used to indicate at least urgency or delay budget information for scheduling data of a predetermined service.

[0121] In addition, when a base station sets up a logical channel, if it sets up the BSR report on this logical channel to use the extended BSR report, the BSR report on the LCG to which the logical channel belongs will use the extended BSR report.

[0122] In one embodiment, when a BSR report is based on an LCG report, any logical channel configured to use extended BSR reporting causes the BSR report to use extended BSR reporting on the LCG.

[0123] In one embodiment, when a BSR report is based on an LCG report, all logical channels configured to use extended BSR reporting will have the BSR report use extended BSR reporting on the LCG.

[0124] In one embodiment, the terminal receives the BSR transmitted based on a reporting scheme using a single logical channel as granularity, and the assistance information is used to indicate at least urgency or delay budget information for scheduling data of a given service.

[0125] In one embodiment, when the base station configures a logical channel, it configures the BSR report on this logical channel to use the extended BSR report, in which case the report on the logical channel uses the extended BSR report.

[0126] In one embodiment, the method includes receiving reference information transmitted from a terminal, the reference information indicating whether the terminal supports or does not support the capability to report the BSR and / or indicating whether the terminal is expected to report the BSR; determining the configuration information based on the reference information; transmitting configuration information to the terminal, the configuration information being used to instruct the terminal to report the BSR; and receiving a buffer status report (BSR) transmitted by the terminal including assistance information, the assistance information being used to indicate at least the urgency of scheduling data for a predetermined service.

[0131] In one embodiment, configuration information is sent to a terminal, the configuration information being used to instruct the terminal to report the BSR. A buffer status report (BSR) including assistance information is sent to an access network device, the assistance information being used to indicate at least the urgency of scheduling data for a predetermined service.

[0132] In one embodiment, configuration information is sent to a terminal, and the configuration information is used to instruct the terminal to report the BSR with terminal granularity, the terminal to report the BSR with logical channel group (LCG) granularity, or the terminal to report the BSR with logical channel granularity. A buffer status report (BSR) including assistance information is sent to an access network device, and the assistance information is used to indicate at least information such as urgency or delay budget for scheduling data of a predetermined service.

[0133] In addition, in a scenario where the terminal is reported at a granularity level, if the base station determines that the terminal is a terminal that executes the XR service, the terminal must report the BSR using an extended BSR report format, i.e., the BSR must include the support information.

[0134] In a scenario where logical channel group (LCG) reporting is performed as granularity, if the base station determines that the terminal is a terminal that performs XR service, the base station notifies the terminal that the extended BSR report format must be used for the specific LCG, and that the terminal can continue to use the pre-extension BSR report format for LCGs other than the specific LCG. The extended BSR report format includes the support information in the BSR. In one embodiment, when configuring a logical channel group, the base station can configure the BSR report on this LCG to use the extended BSR report.

[0135] In addition, in a scenario in which the BSR is reported at the granularity of a logical channel, if the base station determines that the terminal is a terminal that executes an XR service, it notifies the terminal that an extended BSR report format needs to be used for a specific logical channel.
