FIELD

[0001] Various example embodiments of the present disclosure generally relate to the field of telecommunication and in particular, to methods, devices, apparatuses and computer readable storage medium for measurement buffer status reporting. BACKGROUND

[0002] With the development of mobile communication technology, the number of devices and data flow in mobile network are increasing. This trend imposes greater demands on network management and resource allocation, particularly in terms of mobility management and resource management (RRM). In this case, measurement buffer size report (MBSR) reporting enables network management systems to make more precise resource allocation decisions by gathering and reporting status information from network devices. With the help of machine learning technology, MBSR in mobile networks can not only enhance network operational efficiency but also effectively reduce resource consumption, which is well worth studying.

For example, the AI / ML-based beam management targets spatial and / or time beam prediction for overhead and latency reduction.

[0045] FIG. 1 illustrates an example communication environment 100 in which example embodiments of the present disclosure can be implemented. In the communication environment 100, a plurality of communication devices, including a first apparatus 110 and a second apparatus 120, can communicate with each other. In the example of FIG. 1, the first apparatus 110 may be a UE and the second apparatus 120 may be a base station serving the UE.

[0047] In the following, for the purpose of illustration, some example embodiments are described with the first apparatus 110 operating as a UE and the second apparatus 120 operating as a base station.

[0051] In some solutions, the 3rd generation partnership project (3GPP) release 19 study item on AI / ML for mobility in NR includes objectives shown in the following Table I. Table 1 The study will focus on mobility enhancement in RRCCONNECTED mode over air interface by following existing mobility framework, i.e., handover decision is always made in network side. Mobility use cases focus on standalone NR PCell change. UE-side and network-side AI / ML model can be both considered, respectively. Study and evaluate potential benefits and gains of AI / ML aided mobility for network triggered L3-based handover, considering the following aspects: • AI / ML based RRM measurement and event prediction, • Cell-level measurement prediction including intra and inter-frequency (UE sided and NW sided model) [RAN2] • Inter-cell Beam-level measurement prediction for L3 Mobility (UE sided and NW sided model) [RAN2] • HO failure / RLF prediction (UE sided model) [RAN2] • Measurement events prediction (UE sided model) [RAN2] • Study the need / benefits of any other UE assistance information for the network side model [RAN2] • The evaluation of the AI / ML aided mobility benefits should consider HO performance KPIs (e g., Ping-pong HO, HOF / RLF, Time of stay, Handover interruption, prediction accuracy, and measurement reduction) etc.) and complexity tradeoffs [RAN2] • NOTE: Simulation assumption and methodology can leverage TR 38.901, 38.843 and 36.839. And leave the detail discussion to RAN2 • Potential AI mobility specific enhancement should be based on the Rei 19 AI / ML-air interface WID general framework (e.g. LCM, performance monitoring etc) [RAN2] • NOTE: This would only be treated after sufficient progress is made in the Rel-19 AI / ML air interface WID • Potential specification impacts of AI / ML aided mobility [RAN2] • Evaluate testability, interoperability, and impacts on RRM requirements and performance [RAN4] • NOTE 1: RAN1 / 3 work can be triggered via LS • NOTE 2: RAN4 scope / work can be defined and confirmed by RAN#105 after some RAN2 discussions (within the RAN4 pre-allocated TUs) NOTE 3: To avoid duplicate study with “AI / ML for NG-RAN” led by RAN3 • NOTE 4: Two-sided model is not included

[0052] In some solutions, BSR (Buffer Status Report) may be MAC Control Element (MAC CE) that carries the information of how much data is in the user equipment (UE) buffer to be sent out. It is supported in both LTE and NR standards for optimizing the UL 5 resource usage by the network. This mechanism allows the network to allocate UL resources (UL Grant) only when the UE has something to transmit and attempt to limit the amount of over-allocation. There is however always some uncertainty of the allocated resources by the base station as the Buffer Size of the BSR MAC CE is only 5 or 8 bits long and instead of reporting actual bytes in the buffer the UE uses the pre-defined table 10 in Table 2 below to match the actual BSR side to a BSR range, thus the base station only works with a range. The formats for the BSR reporting by the UE are specified, in some predefined standard, as shown in the following Table 2. FIG. 2A illustrates a short BSR and short truncated BSR MAC CE in accordance with the predefined standard. FIG. 2B illustrates a long BSR and long truncated BSR MAC CE in accordance with the predefined 15 standard. Table 2 Buffer Status Report MAC CE Buffer Size: The Buffer Size field identifies the total amount of data available according to the data volume calculation procedure in a predefined standard such as TS 38.322 and 38.323 across all logical channels of a logical channel group after the MAC PDU has been built (i.e. after the logical channel prioritization procedure, which may result the value of the Buffer Size field to zero). The amount of data is indicated in number of bytes. The size of the RLC and MAC headers are not considered in the buffer size computation. The length of this field for the Short BSR format and the Short Truncated BSR format is 5 bits. The length of this field for the Long BSR format and the Long Truncated BSR format is 8 bits. The values for the 5-bit and 8-bit Buffer Size fields are shown in Tables in a predefined standard, respectively. An example Table for the buffer size filed is shown in Table 3 below. For the Long BSR format and the Long Truncated BSR format, the Buffer Size fields are included in ascending order based on the LCGi. For the Long Truncated BSR format the number of Buffer Size fields included is maximized, while not exceeding the number of padding bits. NOTE: The number of the Buffer Size fields in the Long BSR and Long Truncated BSR format can be zero. Table 3 Buffer size levels (in bytes) for 5-bit Buffer Size field Index BS value Index BS value Index BS value Index BS value 0 0 8 <102 16 < 1446 24 <20516 1 < 10 9 < 142 17 <2014 25 <28581 2 < 14 10 < 198 18 < 2806 26 <39818 3 <20 11 <276 19 <3909 27 < 55474 4 <28 12 <384 20 < 5446 28 < 77284 5 <38 13 <535 21 < 7587 29 <107669 6 <53 14 <745 22 <10570 30 <150000 7 <74 15 <1038 23 <14726 31 >150000

[0053] In some other solutions, RRC measurement configuration does support configuration of logged measurements, as described in the following Table 4. The UE can be configured to measure and log periodic measurements based on defined criteria, such 5 as the area where the UE is located. NG-RAN may retrieve stored logged measurement information by means of the UE information procedure. The logging will continue until the configuration is removed or timer T330 expires. This configuration is intended for measurement collection for Minimization of Drive-Testing (MDT) and it has the following disadvantages. Firstly, the network cannot configure measurement event conditions as conditions to report the logged measurements. Also, there is no method to select how many time steps are logged or reported. Secondly, the NG-RAN needs to collect the logged measurements with the UE information procedure and it may need to do this repeatedly, as show below, which is inefficient. Table 4 1 >if the logMeasReport is included in the UEInformationResponse'. 2> submit the UEInformationResponse message to lower layers for transmission via SRB2; 2> discard the logged measurement entries included in the logMeasInfoList from VarLogMeasReport upon successful delivery of the UEInformationResponse message confirmed by lower layers; l>else: 2> submit the UEInformationResponse message to lower layers for transmission via SRB1

[0054] In some solutions, the RRC configuration is proposed that includes various conditions to formulate event based mechanisms for UE to start and exit the time series measurement data logging at the UE side.

[0055] In some other solutions, a data collection buffer was proposed for ML training data collection. It enables the network to configure the UE to collect a log of measurements, also in connected UEs, and the UE to report how many samples it has collected and the network to request the UE to transfer the collected data.

[0056] Buffer status report (BSR) helps optimize uplink (UL) resources by allocating UL grants only when the user equipment (UE) has data to transmit, thereby avoiding resource wastage by allocating only the required amount of resources for Physical Uplink Shared Channel (PUSCH) transmission.

[0057] Legacy BSR, a Medium Access Control (MAC) Control Element (CE) reported by the UE to the network, is utilized by the network for UL grant allocation (resource for PUSCH) for PUCCH / PUSCH data transmission in the UL. Radio measurements such as Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and Channel Quality Indicator (CQI) are reported through different mechanisms and are not part of the BSR. Reusing the legacy BSR framework to report the measurement data buffer size at the UE presents a drawback, as the measurement data buffer size may be large (considering AI / ML frameworks) compared to the actual data buffer size. The network may not be able to differentiate between these buffer sizes during UL grant allocation, leading the network not able to prioritize the allocation for high-priority data when resources are scarce.

[0058] Legacy BSR is designed with either a 5-bit table (short BSR) or an 8-bit table (long BSR), which is relatively static. For measurement data, more flexibility may be required due to the varying radio environment caused by mobility (especially in Frequency Range 2, FR2). Legacy BSR is a feature within the MAC entity, which may not be well applied for Layer 1 (LI) or Layer 3 (L3) radio measurement and reporting procedures. In other words, measurement specific buffer size reporting aimed at reducing overhead should not be confined only to Layer 2 (L2).

[0059] In accordance with some example embodiments of the present disclosure, there is provided a solution for measurement buffer size reporting for ML mobility. The layer 3 measurement reports are sent by UE to gNB through different manners and one of the manners is to report it via RRC signaling message over the Signaling Radio Bearer (SRB). The BSR for SRB consists of the size of the RRC signaling message(s) to be sent to the gNB. The layer 2 and layer 1 measurements are sent to gNB via MAC CE and other layer 2 mechanisms. As described above, due to legacy measurements and AI measurement prediction, the radio measurements may be large, and it may be combined as part of BSR since network would not be able to differentiate between the buffer size of the regular RRC signaling message and the radio measurements.

[0060] To address those problems, in the solution according to the example embodiments of the present disclosure, UE may send BSR and Measurement Buffer Status Report (MBSR) to gNB if UE has both RRC signaling information and the measurement data to be transmitted in uplink. UE may just send MBSR without the need of BSR if UE has only the measurement data. In addition, gNB may provide UL grant to the UE with a priority indication to prioritize the specific type of data to be transmitted.

For the purpose of discussion, the signaling flow 300 will be discussed with reference to FIG. 1, for example, by using the first apparatus 110 and the second apparatus 120. It is noted that the order of acts / steps shown in FIG. 3 is only an example not limitation.

[0063] The first apparatus 110 receives (3005) a configuration of a measurement buffer status report for data associated with at least one measurement from the second apparatus 120. In other words, the second apparatus 120 transmits (3005) the configuration of thea measurement buffer status report for data associated with at least one measurement to the first apparatus 110.

[0064] In some example embodiments, the configuration of the measurement buffer status report (also referred to as MBSR configuration) may indicate at least one of the followings: a measurement buffer size in byte, at least one prioritization rule for a plurality of types of data, at least one criterion for reporting the measurement buffer status report, at least one condition triggering the measurement buffer status report, a periodicity of the measurement buffer status report, or an indication of a support of measurement buffer status report switching initiated by the first apparatus 110. In some other example embodiments, the measurement buffer status report may further indicate at least one priority of the at least one data.

[0065] In some example embodiments, the foregoing plurality of types of data may include a type of data transmitted to the second apparatus via a control channel or a shared channel, and / or a type of data associated with at least one measurement. In some examples, the type of data associated with at least one measurement may include a type of measurement data collected by the first apparatus 110 without using a model, and / or a type of model-based prediction data. As used herein, the term “model-based prediction data” may refer to data predicted by a model or data generated from a prediction of a model. The term model-based prediction data may also be referred to as model-based predicted data or AI / ML based prediction or predicted data. An AI / ML based functionality at the first apparatus 110 and / or the second apparatus 120 may provide the model-based prediction data. For example, the type of model-based prediction data may include at least one of: a model-based radio resource management measurement, a predicted measurement event, a predicted radio link failure, or further model-based prediction data. These prediction data or predicted results may have different requirements associated with latency and reliability of obtaining them. It is to be understood that these example model-based prediction data is for the purpose of illustration, without suggesting any limitation. The model-based prediction data may include any suitable type of prediction data generated by a model implemented at the first apparatus 110 and / or the second apparatus 120.

[0066] In some example embodiments, the foregoing at least one prioritization rule may include a rule to prioritize a type of data transmitted to the second apparatus via a control channel or a shared channel. In some example embodiments, the foregoing at least one prioritization rule may include that UL data transmission may be with the highest priority. In some other example embodiments, the foregoing at least one prioritization rule may include a rule to determine priority of a type of model-based prediction data based on a performance of the model. For example, depending on the performance of AI / ML, such as prediction accuracy, Fl score, and so on, the second apparatus 120 may prioritize AI / ML report and corresponding use cases. In some examples, RLF prediction report may be with higher priority as compared to measurement event prediction report and RRM measurement prediction report. Alternatively, the foregoing at least one prioritization rule may include a rule to de-prioritize a type of data associated with the measurement.

[0067] In some example embodiments, the foregoing at least one criterion for reporting the measurement buffer status report may include a periodic measurement buffer status report. In other words, the second apparatus 120 may configure the first apparatus 110 to perform periodic reporting. In some examples, the periodicity may be aligned with measurement report configuration or SMTC configuration. In some another examples, the periodicity may be aligned with TDD frame configuration and uplink slot.

[0068] In some other example embodiments, the foregoing at least one criterion for reporting the measurement buffer status report may include a semi-persistent or aperiodic measurement buffer status report configured by the second apparatus 120. In this case, the periodicity of MBSR may be switched from one granularity to another, which may be aligned with different buffer sizes, and the switch of configuration may be done based on the second apparatus 120 controlled solution.

[0069] Alternatively, the foregoing at least one criterion for reporting the measurement buffer status report may include a semi-persistent or aperiodic measurement buffer status report configured by the first apparatus 110. In this case, the periodicity of MBSR may be switched from one granularity to another, which may be aligned with different buffer sizes, and the switch of configuration may be done based on the first apparatus 110 autonomous solution.

[0070] The first apparatus 110 transmits (3010) a measurement buffer status report based on the configuration to the second apparatus 120. In this case, the measurement buffer status report indicates at least one size of at least one data of at least one type associated with at least one measurement. Then the second apparatus 120 transmits (3015) an indication of at least one resource to the first apparatus 110 for at least one of: the at least one data, or further data to be transmitted from the first apparatus 110 to the second apparatus 120. For example, the indication of the at least one resource may include a grant such as UL grant of the at least one resource. In some example embodiments, the indication indicates at least one priority of at least one of: the at least one first data, or the second data. In other words, the first apparatus 110 receives (3015) the indication of at least one resource from the second apparatus 120 for at least one of: the at least one data of the at least one type, or further data of a further type to be transmitted to the second apparatus 120. For example, the first apparatus 110 may receive (3015) the grant and prioritization order of the at least one data and / or the further data from the second apparatus 120.

[0071] In some example embodiments, the first apparatus 110 may determine the at least one priority of the at least one data based on at least one of: the at least one type of the at least one data, a scenario of the first apparatus 110, or at least one prioritization rule for a plurality of types of data.

[0072] In some example embodiments, the first apparatus 110 may determine the priority information of the at least one data and the further data, based on types of the at least one data and the further data and at least one prioritization rule for a plurality of types of data. In addition, the first apparatus 110 may select target data with a highest priority from the at least one data and the further data based on the priority information, then may transmit the target data to the second apparatus 120 based on the at least one resource.

[0073] In some example embodiments, the foregoing indication of the at least one resource may indicate the priority information of the at least one data and the further data. In some example embodiments, the first apparatus 110 may select target data with a highest priority from the at least one data and the further data based on the priority information, and may transmit the target data to the second apparatus based on the at least one resource.

[0074] In some example embodiments, MB SR may include the measurement buffer size along with the priority of the measurement data. For example, the Failure prediction report has higher priority and needs to be reported immediately when compared to the RRM measurement prediction report. The priority may also vary depending upon the scenario. For example, the RRM measurement prediction report may be considered as high priority, which has same priority as the failure prediction when the first apparatus 110 moves towards the cell edge.

[0075] In some example embodiments, MBSR may include specific priorities. For example, RRM measurement prediction report may have low priority, such as priority 3. In some examples, measurement event prediction report may have high priority, such as priority 2. In some other examples, failure prediction report may have highest priority, such as priority 2.

[0076] In some example embodiments, the second apparatus 120 may be able to evaluate the BSR and / or MBSR buffer sizes and allocate the grant based on the available PUSCH resources and the priority of the data. For example, the second apparatus 120 may allocate the resource based on the priority information received in MBSR.

[0077] In some example embodiments, the MBSR format may be defined similar to BSR format, that is, short MBSR and long MBSR but with additional “priority” field. For example, FIG. 4 illustrates a format of MAC CE short MBSR in accordance with some example embodiments of the present disclosure. As illustrated, the MAC CE may include a field 410 indicating a logical channel identifier (ID) of a channel for the corresponding data transmission, a filed 420 indicating a size of the corresponding data, and a field 430 indicating priority of the corresponding data.

[0078] In some example embodiments, the UL grant provided to the UE may consist of the priority indication to UE for prioritizing the type of data to be transmitted. For example, UL grant may indicate UE to prioritize prediction report or legacy measurement report.

[0079] In some example embodiments, if the first apparatus 110 receives the configuration of the measurement buffer status report, the first apparatus 110 may initiate a first measurement buffer status report transmission such as a first periodic measurement buffer status report transmission based on the configuration. In addition, if the first apparatus 110 receives a measurement buffer status report switching command from the second apparatus 120, and the measurement buffer status report switching command indicates a further configuration of the measurement buffer status report different from the configuration, the first apparatus 110 may stop the first measurement buffer status report transmission, and may initiate a periodic measurement buffer status report transmission such as a second periodic measurement buffer status report transmission based on the further configuration.

[0080] Alternatively, or in addition, in some example embodiments, in response to receiving the configuration of the measurement buffer status report, the first apparatus 110 may initiate a first measurement buffer status report transmission such as a first periodic measurement buffer status report based on the configuration. If at least one condition for switching a measurement buffer status report is satisfied, the first apparatus 110 may determine a further configuration of the measurement buffer status report different from the configuration. The first apparatus 110 may stop the first measurement buffer status report transmission, and may initiate a periodic measurement buffer status report transmission such as a second periodic measurement buffer status report transmission based on the further configuration.

[0081] In some example embodiments, the first apparatus 110 may transmit capability information regarding transmitting the measurement buffer status report to the second apparatus 120. In some examples, the measurement buffer status report may be included in at least one of: a medium access control control element, a radio resource control message, or uplink control information. In some example embodiments, the second apparatus 120 may determine a configuration of the measurement buffer status report based on the capability information. In some examples, the measurement buffer status report further indicates at least one priority of the at least one first data.

[0082] The first apparatus 110 transmit (3020) at least one of the at least one data or the further data to the second apparatus 120, using the at least one resource based on priority information of the at least one data and the further data. In some example embodiments, the first apparatus 110 may transmit a buffer status report indicating a size of the further data to the second apparatus 120. In this case, the further data may be transmitted to the second apparatus 120 via a control channel or a shared channel.

[0083] Reference is made to FIG. 5, which illustrates a signaling flow 500 of MBSR functionalities according to some example embodiments of the present disclosure. For the purpose of discussion, the signaling flow 500 will be discussed with reference to FIG. 1, for example, by using the first apparatus 110 as UE 510 and the second apparatus 120 as gNB 520. It is noted that the order of acts / steps shown in FIG. 5 is only an example not limitation.

[0084] The signaling steps in FIG. 5 enables MBSR related mechanism between UE 510 and gNB 520. The UE 510 transmits (5010) capability signaling between UE 510 and gNB 520 to support MBSR for AI / ML enabled use cases. Then the gNB 520 determines (5015) MBSR configuration and report prioritization. The gNB 520 analyzes the UE capabilities and determines the appropriate MBSR configuration. This includes setting parameters like measurement buffer (MB) size, prioritization rules for different types of data (e.g., prediction reports, measurement reports, UL data), triggering conditions for MBSR, and reporting criteria. After gNB 520 determining MBSR configuration and report prioritization, the gNB 520 transmits (5020) the configured MBSR parameters to the UE 510. This information enables the UE 510 to understand how to prioritize and buffer data for transmission. The configuration message and parameters are determined at gNB 520 before.

[0085] The UE 510 enables (5025) UE-sided AI / ML functionality for training, inference, and so on. In some example embodiments, the UE-sided AI / ML functionality may include RRM measurement prediction, for predicting future RRM measurements based on historical data and current network conditions. In some other example embodiments, the UE-sided AI / ML functionality may include measurement event prediction, for predicting potential measurement events, such as, Event A3 based on the historical RRM measurements. Alternatively, the UE-sided AI / ML functionality may include RLF prediction, for predicting potential radio link failures based on the historical RRM measurements.

[0086] The UE 510 then buffers (5030) data according to the prioritization rules defined in the MB SR configuration. In some example embodiments, the prioritization rules include UL data, which is intended for transmission to the gNB 520. In some other example embodiments, the prioritization rules include measurement report which is on RRM measurements collected by the UE 510. Alternatively, the prioritization rules include prediction report which is on he predicted RRM measurements, measurement events, and RLFs.

[0087] The UE 510 transmits (5035) a MAC CE transport block to the gNB. In some example embodiments, the block includes BSR indicating the amount of data buffered by the UE 510. Alternatively, the block includes MB SR indicating the amount of data buffered at UE 510 containing the legacy measurement and AI / ML based prediction report, for example, predicted RRM measurements, measurement events, and RLFs.

[0088] In some example embodiments for prioritize prediction report, the gNB 520 allocates (5040) an uplink grant to the UE 510, which allows the UE 510 to transmit UL data and prediction report. The grant prioritizes the transmission of the prediction report. In some example embodiments, the report includes RLF prediction report on predicted radio link failures, such as, true or false. In some other example embodiments, the report includes measurement event prediction report which is on predicted measurement events, for example, measurement Event A3 true or false. Alternatively, the report includes RRM measurement prediction report which is on predicted RRM measurements, e.g., in time series. Then the UE 510 transmits (5045) the UL data to the gNB 520 via PUSCH, including the ML prediction-based report.

[0089] In some other example embodiments for prioritize legacy measurement report, the gNB allocates (5050) an uplink grant to the UE 510, which allows the UE 510 to transmit UL data and measurement. The grant prioritizes the transmission of the measurement report. Then the UE 510 transmits (5055) the UL data to the gNB 520, including the measurement report.

[0090] Alternatively, for prioritize UL data transmission only, the gNB allocates (5060) an uplink grant to the UE 510, which allows the UE 510 to transmit UL data. Then UE 510 transmits (5065) the UL data according to the gNB allocation.

[0091] Reference is made to FIG. 6, which illustrates a signaling flow 600 of periodic MBSR framework according to some example embodiments of the present disclosure. For the purpose of discussion, the signaling flow 600 will be discussed with reference to FIG. 1, for example, by using the first apparatus 110 as UE 610 and the second apparatus 120 as gNB 620. It is noted that the order of acts / steps shown in FIG. 6 is only an example not limitation.

[0092] At 6005, MBSR procedure between UE 610 and gNB 620 indicates the process of generic MBSR functionalities shown in FIG. 5. The gNB 620 transmits (6010) a triggering indication to the UE 620, which signifies the start of the MBSR procedure. In some example embodiments, the indication may be based on RRC procedure by including to use certain MBSR configuration, such as buffer size, reporting periodicity to a given prioritization. Alternatively, the indication may be based on L1 / L2 signaling such as DCI or MAC CE. If the mapping between MBSR configuration is already configured at 6005, then lower layer signaling may be used to trigger the indication.

[0093] The UE 610 then buffers (6015) data according to the prioritization rules defined in the MBSR configuration. In some example embodiments, the prioritization rules include UL data, which is intended for transmission to the gNB 620. In some other example embodiments, the prioritization rules include measurement report which is on RRM measurements collected by the UE 610. Alternatively, the prioritization rules include prediction report which is on he predicted RRM measurements, measurement events, and RLFs.

[0094] The UE 610 transmits (6020) MAC CE transport block and BSR and MBSR to the gNB 620. Then the gNB 620 transmits (6025) UL grant allocated with prioritization to the UE 610. After receiving UL grant, the UE 610 transmits (6030) UL data transmission, legacy measurement report, and ML prediction based report to the gNB 620, then transmits (6035) MAC CE transport block, BSR and MBSR to gNB 620. The above described 6020 to 6035 are periodic MBSR procedure. In this case, the general status reporting, UL grant allocation and data transmission with measurement report and prediction report are discussed in FIG. 5 as well.

[0095] Reference is made to FIG. 7, which illustrates a signaling flow 700 of semi-persistent or aperiodic MB SR framework based on network controlled solution according to some example embodiments of the present disclosure. For the purpose of discussion, the signaling flow 700 will be discussed with reference to FIG. 1, for example, by using the first apparatus 110 as UE 710 and the second apparatus 120 as gNB 720. It is noted that the order of acts / steps shown in FIG. 7 is only an example not limitation.

[0096] At 7005, MBSR procedure between UE 710 and gNB 720 indicates the process of generic MBSR functionalities shown in FIG. 5. The gNB 720 transmits (7010) a triggering indication to the UE 720, which signifies the start of the MBSR procedure. In some example embodiments, the indication may be based on RRC procedure by including to use certain MBSR configuration, such as buffer size, reporting periodicity to a given prioritization. Alternatively, the indication may be based on L1 / L2 signaling such as DCI or MAC CE. If the mapping between MBSR configuration is already configured at 7005, then lower layer signaling may be used to trigger the indication.

[0097] The UE 710 then buffers (7015) data according to the prioritization rules defined in the MBSR configuration. In some example embodiments, the prioritization rules include UL data, which is intended for transmission to the gNB 720. In some other example embodiments, the prioritization rules include measurement report which is on RRM measurements collected by the UE 710. Alternatively, the prioritization rules include prediction report which is on he predicted RRM measurements, measurement events, and RLFs.

[0098] The UE 710 transmits (7020) MAC CE transport block and BSR and MBSR to the gNB 720. Then the gNB 720 transmits (7025) UL grant allocated with prioritization to the UE 710. After receiving UL grant, the UE 710 transmits (7030) UL data transmission, legacy measurement report, and ML prediction based report to the gNB 720, then transmits (7035) MAC CE transport block, BSR and MBSR to gNB 720. The above described 7020 to 7035 are periodic MBSR procedure based on one MBSR configuration. In this case, the general status reporting, UL grant allocation and data transmission with measurement report and prediction report are discussed in FIG. 5 as well, and the buffer size Bl and reporting periodicity T1 are applied.

[0099] Then the gNB 720 decides (7040) to change the prioritization order for the MBSR procedure and prepares the new MBSR configuration such as new buffer size and reporting periodicity. In addition, the gNB 720 transmits (7045) the corresponding MBSR switching command to the UE 730.

[0100] After receiving the corresponding MBSR switching command, the UE 710 buffers (7050) data according to the new prioritization rules defined in the new MBSR configuration. Then the UE 710 transmits (7055) MAC CE transport block and BSR and MBSR to the gNB 720. Then the gNB 720 transmits (7060) UL grant allocated with prioritization to the UE 710. After receiving UL grant, the UE 710 transmits (7065) UL data transmission, legacy measurement report, and ML prediction based report to the gNB 720, then transmits (7070) MAC CE transport block, BSR and MBSR to gNB 720. The above described 7055 to 7070 are periodic MBSR procedure based on another MBSR configuration. In this case, the general status reporting, UL grant allocation and data transmission with measurement report and prediction report are discussed in FIG. 5 as well, and the buffer size B2 and reporting periodicity T2 are applied.

[0101] Reference is made to FIG. 8, which illustrates a signaling flow 800 of periodic MBSR framework according to some example embodiments of the present disclosure. For the purpose of discussion, the signaling flow 800 will be discussed with reference to FIG. 1, for example, by using the first apparatus 110 as UE 810 and the second apparatus 120 as gNB 820. It is noted that the order of acts / steps shown in FIG. 8 is only an example not limitation.

[0102] At 8005, MBSR procedure between UE 810 and gNB 820 indicates the process of generic MBSR functionalities shown in FIG. 5. The gNB 820 transmits (8010) a triggering indication with UE autonomous switch MBSR configuration (also referred to as an “indication” herein after) to the UE 820, which signifies the start of the MBSR procedure. In some example embodiments, the indication may be based on RRC procedure by including to use certain MBSR configuration, such as buffer size, reporting periodicity to a given prioritization. Alternatively, the indication may be based on L1 / L2 signaling such as DCI or MAC CE. If the mapping between MBSR configuration is already configured at 8005, then lower layer signaling may be used to trigger the indication. It is to be understood that the UE autonomous switch MB SR configuration may include one or more of: a measurement buffer size in byte, at least one prioritization rule for a plurality of types of data, at least one criterion for reporting the measurement buffer status report, at least one condition triggering the measurement buffer status report, a periodicity of the measurement buffer status report, or an indication of a support of measurement buffer status report switching initiated by UE. That is, the gNB 820 may pre-configure the combination of buffer sizes, periodicities, and prioritization rules for the UE 810 to autonomously switch.

[0103] The UE 810 then buffers (8015) data according to the prioritization rules defined in the MB SR configuration. In some example embodiments, the prioritization rules include UL data, which is intended for transmission to the gNB 820. In some other example embodiments, the prioritization rules include measurement report which is on RRM measurements collected by the UE 810. Alternatively, the prioritization rules include prediction report which is on he predicted RRM measurements, measurement events, and RLFs.

[0104] The UE 810 transmits (8020) MAC CE transport block and BSR and MBSR to the gNB 820. Then the gNB 820 transmits (8025) UL grant allocated with prioritization to the UE 710. After receiving UL grant, the UE 810 transmits (8030) UL data transmission, legacy measurement report, and ML prediction based report to the gNB 820, then transmits (8035) MAC CE transport block, BSR and MBSR to gNB 820. The above described 8020 to 8035 are periodic MBSR procedure based on one MBSR configuration. In this case, the general status reporting, UL grant allocation and data transmission with measurement report and prediction report are discussed in FIG. 5 as well, and the buffer size Bl and reporting periodicity T1 are applied.

[0105] Then the UE 810 decides (8040) to change the prioritization order for the MBSR procedure without the gNB indication command. The UE 710 buffers (8050) data according to the new prioritization rules defined in the new MBSR configuration. Then the UE 810 transmits (8055) MAC CE transport block and BSR and MBSR to the gNB 820. Then the gNB 820 transmits (8060) UL grant allocated with prioritization to the UE 810. After receiving UL grant, the UE 810 transmits (8065) UL data transmission, legacy measurement report, and ML prediction based report to the gNB 820, then transmits (8070) MAC CE transport block, BSR and MBSR to gNB 820. The above described 8055 to 8070 are periodic MBSR procedure based on another MBSR configuration. In this case, the general status reporting, UL grant allocation and data transmission with measurement report and prediction report are discussed in FIG. 5 as well, and the buffer size B2 and reporting periodicity T2 are applied.
