[0006] Once the first event is determined to have occurred, at least one received reference signal is measured within the first time frame to obtain a first measurement result;
[0007] If the first measurement result satisfies the first condition, determine the Layer 1 Reference Signal Received Power (L1-RSRP) report;
[0008] Send the L1-RSRP report to the network device;
[0009] The delay of the L1-RSRP report is the time interval between the time when the first event occurs and the time when the L1-RSRP report is sent.
[0010] A second aspect of this disclosure provides an uplink communication method, which is executed by a network device, and the method includes:
[0011] The receiving terminal sends a Layer 1 reference signal received power (L1-RSRP) report.
[0012] The L1-RSRP report is determined by the terminal after it determines that the first measurement result meets the first condition. The first measurement result is obtained by the terminal determining that the first event has occurred and measuring at least one received reference signal within a first time period.
[0013] The delay of the L1-RSRP report is the time interval between the time when the first event occurs and the time when the L1-RSRP report is sent.
[0014] A third aspect of this disclosure provides a terminal, the terminal comprising:
[0015] The processing module is used to determine that a first event has occurred, and to measure at least one received reference signal within a first time period to obtain a first measurement result;

[0020] The transceiver module is used to receive the Layer 1 Reference Signal Received Power (L1-RSRP) report sent by the terminal.
[0021] The L1-RSRP report is determined by the terminal after it determines that the first measurement result meets the first condition. The first measurement result is obtained by the terminal determining that the first event has occurred and measuring at least one received reference signal within a first time period.
[0022] The delay of the L1-RSRP report is the time interval between the time when the first event occurs and the time when the L1-RSRP report is sent.
[0023] The solution proposed in this embodiment involves determining that a first event has occurred, measuring at least one received reference signal within a first time period to obtain a first measurement result; determining that the first measurement result satisfies a first condition, and determining a Layer 1 Reference Signal Received Power (L1-RSRP) report; and sending an L1-RSRP report to the network device. The delay of the L1-RSRP report is the time interval between the occurrence of the first event and the time of report transmission. This enables the terminal to promptly report wireless link quality information to the network, effectively improving the system's communication efficiency and allowing the network to promptly obtain wireless link quality information and quality changes, thus saving signaling overhead.

[0103] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.
[0104] As shown in Figure 1, the communication system 100 includes a terminal 101 and a network device 102.
[0105] In some embodiments, terminal 101 includes, for example, at least one of the following: mobile phone, wearable device, Internet of Things (IoT) device, Narrow Band-Internet of Things (NB-IoT) device, satellite communication device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, wireless terminal device in smart home, and red-capped terminal, but is not limited thereto.

The processes and information interactions between these internal interfaces can be implemented by software or programs.
[0108] 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.
[0109] 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 proposed 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 proposed in this disclosure are also applicable to similar technical problems.
[0110] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. 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.
[0111] The embodiments disclosed herein can be applied to Non-terrestrial Networks (NTN), IoT-NTN, 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, Narrow Band-IoT (NB-IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).
[0112] In communication systems, the quality of the wireless link between a terminal and network equipment can be determined through several measurement metrics. These include, for example, Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and Signal-to-Interference Plus Noise Ratio (SINR).
[0113] In some embodiments, Layer 1 (L1, i.e., physical layer) - RSRP is a key metric used in wireless communication systems. It provides a measure of the power level of the reference signal received by a terminal from a base station, which is crucial for determining the quality of the wireless link.
[0114] In some embodiments, the L1-RSRP measurement and reporting process may include, but is not limited to, the following steps:
[0115] Beam scanning: The base station (gNB) transmits reference signals in all directions (beam scanning);
[0116] Measurement: The UE measures the received power (L1-RSRP) of these reference signals;
[0117] Report: The UE will report the L1-RSRP measurement value back to the gNB;
[0118] Beam selection: gNB analyzes the L1-RSRP report and selects the beam direction with the highest received power for communication.
[0119] In some embodiments, only periodic and semi-persistent L1-RSRP reporting are defined in legacy L1-RSRP reporting. The UE reports L1-RSRP measurements according to the reporting period configured by the network (NW). However, periodic reporting is costly.
[0120] The uplink communication method and apparatus provided in this disclosure will now be described in detail with reference to the accompanying drawings.
[0121] Figure 2A is an interactive schematic diagram of an uplink communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the present disclosure relates to an uplink communication method, which includes:
[0122] In step S2101, terminal 101 determines that the first event has occurred and obtains the first measurement result.
[0123] In some embodiments, terminal 101 measures at least one received reference signal (RS) to obtain the first measurement result described above.
[0124] In some embodiments, terminal 101 measures at least one reference signal received in a first time period to obtain the first measurement result described above.
[0125] In some embodiments, the L1 report of the terminal 101 is triggered by the first event.
[0126] As an example, the first event triggered above may include at least one of the following:
[0127] At least one new beam (such as L1-RSRP) has better quality than the current beam;
[0128] The quality of the current beam is below a preset threshold;
[0129] The quality of at least one new beam (such as L1-RSRP) is better than that of the RS obtained from the active Transmission Configuration Indication (TCI) state with the Mth best quality.
[0130] Wherein, M is the capability signaling of the subjective terminal 101 configured by Radio Resource Control (RRC).
[0131] Optionally, terminal 101 may indicate only one candidate value or may not support the above-mentioned events.
[0132] As an example, if the L1-RSRP of the current beam is worse than that of other candidate beams, the terminal 101 will report the index of the beam with good quality to the network device 102.
[0133] In some embodiments, the first time mentioned above is the time required for the terminal 101 to perform multi-beam or multi-cell measurements.
[0134] As an example, the first measurement result can be obtained by measuring at least one RS received in the first time period mentioned above, as shown in Figure 2B. T1 in Figure 2B is the first time period mentioned above, which is the measurement time required by terminal 101.
[0135] In some embodiments, the reference signal includes reference signals from at least two serving cells, and the measurement periods corresponding to the reference signals from each serving cell are different, with the first time being the largest measurement period among the at least two measurement periods.
[0136] Each of the above-mentioned serving cells has a different Physical Cell Identifier (PCI).
[0137] As an example, the first event is that the quality (e.g., L1-RSRP) of at least one new beam is better than that of the current beam. Assume the current beam comes from the serving cell, and the new beam comes from a cell with a different PCI (CDP). The two beams have different measurement periods; as an example, this can be illustrated in Figure 2C, where the measurement period of the current beam is T. SSB_serving The measurement period of the new beam is T. SSB_CDP And T SSB_CDP <T SSB_serving The total measurement time (i.e., the first time) that triggers an L1 report is based on the largest measurement period (i.e., T) among multiple measurement periods. SSB_serving It is certain.
[0138] Understandably, if based on T SSB_CDP If the total measurement time is defined by a measurement cycle, then since T SSB_CDP <T SSB_serving When terminal 101 obtains the L1-RSRP of a new beam, it will not yet obtain the L1-RSRP from the current beam. Therefore, terminal 101 cannot compare with the standard and trigger an L1 report. Thus, if it is necessary to measure multiple beams / cells for comparison with the standard defined in different events, the maximum measurement period among the multiple beams or cells will be regarded as the total measurement time to trigger an L1 report.
[0139] In some embodiments, the number of measurement samples required to obtain the first measurement result (i.e., the number of RSs to be measured) is a first value. As an example, it can be shown in Figure 2D.
[0140] Optionally, the first value mentioned above can be configured by the network device 102 or pre-agreed by the protocol.
[0141] Optionally, the first value mentioned above may have a range of values, which may be the L1 filtering coefficient configured by the network device 102, or it may be predetermined by the protocol.
[0142] As an example, suppose we can configure the system to measure N (i.e., the first value) samples, where N can take the values 1, 2, ..., n. Here, N and n are both positive integers.
[0143] In some embodiments, the first time mentioned above is also related to the first numerical value mentioned above.
[0144] In some embodiments, the first time mentioned above is determined based on the scaling factor Q.
[0145] In some embodiments, the first time mentioned above is determined based on the conventional measurement period and the scaling factor Q mentioned above.
[0146] Optionally, the scaling factor Q can be equal to the first value mentioned above.
[0147] Optionally, the scaling factor Q is equal to the minimum value within the range of the first numerical value. For example, if the range of the first numerical value is configured to be 1, 2, ..., n, then the scaling factor Q is 1.
[0148] As an example, the evaluation time for the current beam can be as follows, where DRX refers to Discontinuous Reception (DRX), and ceil(x) is rounded up.
[0149] Evaluation period TL1-RSRP_Measurement_Period_SSB for FR1
[0150] Evaluation period TL1-RSRP_Measurement_Period_SSB for FR2
[0151] As an example, the evaluation time for beams from serving cells with different PCIs can be as follows:
[0152] Inter-cell L1-RSRP measurement period TL1-RSRP_Measurement_Period_SSB_CDP for known cells with different PCIs in FR1
[0153] Inter-cell L1-RSRP measurement period TL1-RSRP_Measurement_Period_SSB_CDP for known cells with different PCIs in FR2
[0154] In step S2102, terminal 101 determines the L1-RSRP report.
[0155] In some embodiments, terminal 101 determines that the first measurement result meets the first condition and determines to trigger L1-RSRP reporting.
[0156] In some embodiments, it is determined that an L1-RSRP report will be triggered, that is, terminal 101 determines that it wants to send the above report to network device 102.
[0157] In some embodiments, after the aforementioned first time, terminal 101 is able to determine whether the obtained first measurement result meets the reporting criteria.
[0158] In some embodiments, if the first measurement result satisfies the first condition, the terminal 101 determines to send the first information to the network device 102, that is, the L1-RSRP report is triggered.
[0159] In some embodiments, the delay of the L1-RSRP report is the time interval between the moment when the first event occurs and the moment when terminal 101 begins to send the L1 report via the air interface.
[0160] It should be noted that the delay in the L1-RSRP report mentioned above refers to the delay time of the L1-RSRP report.
[0161] In some embodiments, the starting point for the L1-RSRP report is when an event occurs in which the beam / cell quality of the current beam / cell and / or other beams / cells has changed (i.e., the first event). From this point in time, terminal 101 needs to evaluate the L1 report through measurement.
[0162] In some embodiments, the end point of the L1-RSRP report is the time when terminal 101 begins sending L1 reports via the air interface.
[0163] In some embodiments, the delay of the L1-RSRP report is less than the first time mentioned above.
[0164] In some embodiments, the delay of the L1-RSRP report is the sum of the first time and the second time.
[0165] The second time mentioned above is the time interval between the moment when the report is determined (that is, the moment when the first measurement result meets the first condition) and the moment when the L1 report is sent.
[0166] In some embodiments, terminal 101 sends the aforementioned L1-RSRP report after a second time period.
[0167] In this embodiment of the application, the terminal 101 cannot send the L1-RSRP report immediately after determining that it needs to send it. Instead, it needs to wait for uplink resources. The second time mentioned above is the uplink resource waiting time (UL resource waiting time).
[0168] In some embodiments, the L1-RSRP report described above can be used for beam management.
[0169] In some embodiments, the first condition described above may include at least one of the following:
[0170] The first measurement result of at least one new beam is better than the first measurement result of the current beam;
[0171] The first measurement result of the current beam is lower than the preset threshold;
[0172] The first measurement result of at least one new beam is better than the RS obtained from the activated TCI state with the Mth best quality.
[0173] In some embodiments, the first information described above can also be used for L1 / L2 (Layer 2, i.e., data link layer) triggered mobility (LTM).
[0174] Optionally, the first event mentioned above may also include other events that can trigger LTM measurements.
[0175] Optionally, in the case of LTM, the terminal needs to measure the L1-RSRP of different cells, and at least one RS measured in the first time mentioned above can come from different cells.
[0176] In step S2103, terminal 101 sends the aforementioned L1-RSRP report.
[0177] In some embodiments, after acquiring uplink resources, terminal 101 can send the L1-RSRP report on the uplink resources.
[0178] In this embodiment of the application, the terminal 101 cannot send the first information immediately after determining that it needs to send it, but needs to wait for uplink resources. The second time is the uplink resource waiting time.
[0179] In some embodiments, the length of the second time period may be longer than the RS measurement period of terminal 101. Therefore, during the second time period, terminal 101 may receive at least one more RS and obtain a second measurement result. As an example, see Figure 2E.
[0180] In some embodiments, the second measurement result still satisfies the first condition, and the first information sent by the terminal 101 may include the second measurement result.
[0181] In some embodiments, the second measurement result still satisfies the first condition, and the first information sent by the terminal 101 still includes the previously obtained first measurement result.
[0182] In some embodiments, the second measurement result still satisfies the first condition, and the terminal 101 determines the measurement result included in the first information based on its own implementation.
[0183] In some embodiments, if the second measurement result does not meet the first condition, the terminal 101 may not send the first information.
[0184] In some embodiments, if the second measurement result does not meet the first condition, the terminal 101 still sends the first information, which includes the second measurement result.
[0185] In some embodiments, if the second measurement result does not meet the first condition, the terminal 101 still sends the first information, which includes the first measurement result.

[0219] In some embodiments, the above methods may include the methods described in the embodiments of the communication system side, terminal side, network device side, etc., which will not be repeated here.
[0220] In this implementation or embodiment, unless there is contradiction, each step can be independent, arbitrarily combined or exchanged in order, optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementations or other embodiments.
[0221] The following is an exemplary description of the methods described in the above embodiments.
[0222] The primary motivation for L1 event-driven / UE-initiated reports is to verify that when beam or cell quality changes, the UE can detect the changes in a timely manner and report the L1-RSRP to the network within the required time according to different event triggering criteria.
[0223] In some embodiments, the delay of an event-triggered L1-RSRP report is defined as follows: the delay of the measurement report is defined as the time between the event that triggers the L1-RSRP measurement report (i.e., the first event in the foregoing embodiments) and the time between the UE starting to send the L1-RSRP measurement report through the air interface.
[0224] In some embodiments, the start and end points of the L1 report are as follows:
[0225] The starting point for L1 reporting is the event that the quality of the current beam / cell or another beam / cell has changed (i.e., the first event in the aforementioned embodiments). From that point onward, the UE needs to evaluate the L1 report through measurements.
[0226] The endpoint of the L1 report is the time when the UE begins sending L1 reports via the air interface.
[0227] In this embodiment of the application, the overall timeline for the L1 report triggered by the event mainly includes two parts, as shown in Figure 2B:
[0228] T1 (i.e., the first time in the aforementioned embodiments) is the measurement time required for multi-beam measurement;
[0229] T2 (also known as the second time in the aforementioned embodiments) is the UL resource waiting time.
[0230] After T1, terminal 101 can acquire L1-RSRP measurement results for multiple beams (i.e., the first measurement results in the aforementioned embodiments) to assess whether the L1 reporting criteria (i.e., the first conditions in the aforementioned embodiments) are met. If met, terminal 101 will trigger an L1 report (the L1 report is also the first information in the aforementioned embodiments). Terminal 101 will request UL resources (i.e., the first request in the aforementioned embodiments), and then when the first UL resource capable of carrying the L1 report (i.e., the PUSCH in the aforementioned embodiments) arrives, terminal 101 can send the L1 report to network device 102.
[0231] In some embodiments, the total delay length may or may not be considered when considering UL resource latency:
[0232] The first scenario: The total L1 reporting delay will be less than the measurement time required for multiple beams / cells (i.e., the first time in the aforementioned embodiments);
[0233] The second type: The total L1 reporting delay includes the measurement time required for multiple beams / cells (i.e., the first time in the aforementioned embodiments) and the delay caused by UL resource waiting time (i.e., the second time in the aforementioned embodiments).
[0234] As an example, the triggering event described above (i.e., the first event in the foregoing embodiments) may include at least one of the following:
[0235] Event 2: The quality of at least one new beam (such as L1-RSRP) is better than that of the current beam;
[0236] Event 1: The quality of the current beam is lower than the preset threshold;
[0237] Event 7: The quality of at least one new beam (e.g., L1-RSRP) is better than that of the RS obtained from the activated TCI state with the Mth best quality.
[0238] Wherein, M is the capability signaling of the subjective terminal 101 configured by Radio Resource Control (RRC).
[0239] Optionally, terminal 101 may indicate only one candidate value or may not support the above-mentioned events.
[0240] Taking Event 2 as an example, assume the current beam comes from the serving cell, and the new beam comes from a cell with a different Physical Cell Identifier (PCI). The two beams have different measurement periods. As an example, as shown in Figure 2C, the measurement period of the current beam is T.SSB_serving The measurement period of the new beam is T. SSB_CDP And T SSB_CDP <T SSB_serving The total measurement time (i.e., the first time) that triggers an L1 report is based on the largest measurement period (i.e., T) among multiple measurement periods. SSB_serving It is certain.
[0241] If based on T SSB_CDP If the total measurement time is defined by a measurement cycle, then since T SSB_CDP <T SSB_serving When terminal 101 obtains the L1-RSRP of a new beam, terminal 101 will not obtain the L1-RSRP from the current beam. Therefore, terminal 101 cannot compare with the standard and trigger an L1 report.
[0242] For event 1, the UE only measures the current beam, and the measurement time only needs to consider one beam.
[0243] For event 7, the UE needs to measure the beam with an active TCI state, and the total measurement time also needs to take into account the measurement cycle of multiple beams.
[0244] Therefore, the measurement time in the event-triggered L1 report (i.e., the first time in the aforementioned embodiments) can be defined as:
[0245] If multiple beams / cells need to be measured for comparison with standards defined in different events, the maximum measurement period among the multiple beams or cells will be considered as the total measurement time that triggers the L1 report.
[0246] In some embodiments, for event-triggered L1 reports, the influence of the physical layer trigger window also needs to be considered. The trigger window can be as shown in Figure 2D.
[0247] In this configuration, multiple L1-RSRP measurement samples can be configured for event evaluation. The trigger window is designed to ensure that multiple results remain stable within the time window for triggering an L1 report. Assume that N samples can be configured, where N can be 1, 2, ..., n. The scaling factor Q within the measurement period is:
[0248] 1. N, which is the number of L1-RSRP measurement samples configured (the first value in the aforementioned embodiments);
[0249] 2. min(N), the minimum configurable value. That is, if the minimum configurable value of N is 1, then Q = 1.
[0250] Compared to the traditional measurement period, the measurement period of the current or candidate beam will be scaled by Q.
[0251] As an example, the evaluation time for the current beam can be as follows, where DRX refers to Discontinuous Reception (DRX), and ceil(x) is rounded up.
[0252] Evaluation period TL1-RSRP_Measurement_Period_SSB for FR1
[0253] Evaluation period TL1-RSRP_Measurement_Period_SSB for FR2
[0254] As an example, the evaluation time for beams from serving cells with different PCIs can be as follows:
[0255] Inter-cell L1-RSRP measurement period TL1-RSRP_Measurement_Period_SSB_CDP for known cells with different PCIs in FR1
[0256] Inter-cell L1-RSRP measurement period TL1-RSRP_Measurement_Period_SSB_CDP for known cells with different PCIs in FR2
[0257] This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.
[0258] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.
[0259] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
