[0119] In some embodiments, the access network device may be composed of a centralized unit (central unit, CU) and a distributed unit (distributed unit, DU), wherein the CU may also be referred to as a control unit (control unit). The CU-DU structure may be used to split the protocol layer of the access network device, with some functions of the protocol layer being centrally controlled by the CU, and the remaining part or all of the functions of the protocol layer being distributed in the DU, and the DU being centrally controlled by the CU, but not limited to this.
[0120] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. A person of ordinary skill in the art can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.
[0121] The following embodiments of the present disclosure can be applied to Figure 1 The communication system 100, or a portion thereof, is shown but is not limited thereto.

[0123] In a communication system, the quality of a wireless link between a terminal and a network device can be determined by some measurement indicators, such as Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), etc.
[0124] In some embodiments, Layer 1 (L1, i.e. physical layer)-RSRP is a key indicator used by wireless communication systems. It provides a measure of the power level of the reference signal received by the terminal from the base station, which is crucial for determining the quality of the wireless link.
[0125] In some embodiments, the L1-RSRP measurement and reporting process may include but is not limited to the following steps:
[0126] Beam scanning: The base station (gNB) sends reference signals in all directions (beam scanning);
[0127] Measurement: The UE measures the received power of these reference signals (L1-RSRP);
[0128] Reporting: The UE reports the L1-RSRP measurement value back to the gNB;
[0129] Beam selection: The gNB analyzes the L1-RSRP report and selects the beam direction with the highest received power for communication.
[0130] In some embodiments, in the legacy L1-RSRP report, only periodic and semi-persistent L1-RSRP reports are defined. The UE will report the L1-RSRP measurement results according to the reporting period configured by the network (NW). However, the overhead of periodic reporting is very large.
[0131] The uplink communication method and device provided by the present disclosure are described in detail below with reference to the accompanying drawings.
[0132] Figure 2A FIG. 1 is an interactive schematic diagram of an uplink communication method according to an embodiment of the present disclosure. Figure 2A As shown, the embodiment of the present disclosure relates to an uplink communication method, and the method includes:
[0133] Step S2101: Terminal 101 obtains a first measurement result.
[0134] In some embodiments, the terminal 101 measures at least one received reference signal (RS) to obtain the above-mentioned first measurement result.
[0135] In some embodiments, the terminal 101 measures at least one reference signal received within a first time to obtain the above-mentioned first measurement result.
[0136] In some embodiments, the measurement of at least one reference signal by the terminal 101 is triggered by an event.
[0137] As an example, the above-mentioned triggered event may include at least one of the following:
[0138] At least one new beam has a better quality (e.g. L1-RSRP) than the current beam.
[0139] The quality of the current beam is lower than the preset threshold;
[0140] The quality (eg, L1-RSRP) of at least one new beam is better than the RS obtained from the activated TCI state with the Mth best quality.
[0141] The above-mentioned M is the capability signaling of the subjective terminal 101 configured by Radio Resource Control (RRC).
[0142] Optionally, the terminal 101 may indicate only one candidate value or may not support the above event.
[0143] As an example, for example, when the L1-RSRP of the current beam is worse than the L1-RSRP of other candidate beams, the terminal 101 will report the index of the beam with good quality to the network device 102.
[0144] In some embodiments, the first time mentioned above is the time required for terminal 101 to perform multi-beam measurement.
[0145] In some embodiments, the number of measurement samples required to obtain the first measurement result (ie, the number of RSs required to be measured) may be configured by the network device 102 .
[0146] As an example, measuring at least one RS received within the first time to obtain a first measurement result may be as follows: Figure 2B As shown, Figure 2B T1 in the figure is the first time mentioned above, that is, the measurement time required by the terminal 101.
[0147] Step S2102: Terminal 101 determines first information.
[0148] In some embodiments, the terminal 101 determines that the first measurement result satisfies the first condition, and determines to send the first information to the network device 102 .
[0149] In some embodiments, after the first time, the terminal 101 can determine whether the obtained first measurement result meets the reporting criteria.
[0150] In some embodiments, the first measurement result satisfies a first condition, and the terminal 101 determines to send the first information to the network device 102, that is, the first information is triggered.
[0151] Furthermore, the terminal 101 may request uplink resources to send the above-mentioned first information.
[0152] In some embodiments, the name of the above-mentioned first information is not limited, and it may be, for example, "beam report", "quality report", "beam quality report", "L1-RSRP report", "quality information", "beam quality", etc.
[0153] In some embodiments, the first information is L1-RSRP reporting.
[0154] In some embodiments, the first information may be used for beam management.
[0155] In some embodiments, the first condition may include at least one of the following:
[0156] A first measurement result of at least one new beam is better than a first measurement result of a current beam;
[0157] The first measurement result of the current beam is lower than a preset threshold;
[0158] 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.
[0159] In some embodiments, the first information may also be used for L1 / L2 (Layer 2, ie, data link layer) triggered mobility (L1 / L2 triggered mobility, LTM).
[0160] Optionally, the above events may also include other events that can trigger the measurement of LTM.
[0161] Optionally, in the case of LTM, the terminal needs to measure L1-RSRP of different cells, and the at least one RS measured at the first time may come from different cells.
[0162] Step S2103: Terminal 101 sends a first request.
[0163] In some embodiments, after the terminal 101 determines to send the above-mentioned first information, it can send a first request to the network device 102.
[0164] In some embodiments, the first request is used to request uplink (UL) resources to send the first information.
[0165] In some embodiments, the first request is used to request a first resource, and the first resource is used by the terminal 101 to send the first information.
[0166] In some embodiments, the first resource is a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH).
[0167] In some embodiments, the first request is sent via a physical uplink control channel (PUCCH).
[0168] In some embodiments, the first resource may be dynamically scheduled by the network device 102 through downlink control information (Downlink Control Information, DCI).
[0169] As an example, Figure 2C As shown, the terminal 101 can send a first request at Ta (that is, the first PUCCH after determining the above-mentioned first information), and wait for the DCI sent by the network device 102 at Tb, and then send the above-mentioned first information at Tc (that is, send the first information on the first resource scheduled by the above-mentioned DCI).
[0170] In some embodiments, the first resource may also be pre-configured by the network device 102 .
[0171] Optionally, the first resource is the first available uplink transmission opportunity (i.e., PUSCH transmission opportunity (PUSCH Occasion, PO)) of the terminal 101 after sending the first request. The starting time domain resource unit corresponding to the first resource and the last time domain resource unit for sending the first request are separated by at least a preset number of time domain resource units.
[0172] Optionally, the time domain resource unit may be a time domain symbol, or a time slot, etc.
[0173] Optionally, the preset number of time domain resource units is used by the network device 102 to parse the PUCCH of the first request.
[0174] Optionally, the above preset number may be configured by the network device 102 or may be pre-agreed upon by a protocol.
[0175] As an example, Figure 2D As shown, the terminal 101 can send the first request at Ta (that is, the first PUCCH after determining the first information), and send the first information at Tb. The UL resource carrying the first information is located X symbols after the last symbol of the first request sent on the PUCCH. That is, there is a minimum interval between the UL resource carrying the first information and the PUCCH sending the first request, that is, the X symbols, and the X symbols can be used by the network device 102 to decode the PUCCH.
[0176] Step S2104: Terminal 101 sends the first information after the second time.
[0177] In some embodiments, terminal 101 sends the first information after a second time.
[0178] In the embodiment of the present application, the terminal 101 cannot send the first information immediately after determining to send the first information, but needs to wait for uplink resources. The second time is the uplink resource waiting time (UL resource waiting time).
[0179] In some embodiments, the starting moment of the second time is the moment when the terminal 101 determines the first information according to the first measurement result.
[0180] In some embodiments, the end moment of the second time is when the terminal 101 obtains the first available uplink resource.
[0181] Optionally, the first available uplink resource is defined as the PUCCH to which the terminal 101 sends the first request.
[0182] Optionally, the first available uplink resource is defined as the PUSCH.
[0183] Optionally, the first available uplink resource is defined as a PUSCH used to carry the first information.
[0184] It can be understood that, when the first available uplink resource is located as the PUCCH, the terminal 101 still sends the first information on the PUSCH after the PUCCH.
[0185] In some embodiments, the length of the second time may be longer than the RS measurement period of the terminal 101. Therefore, within the second time, the terminal 101 may receive at least one RS and obtain a second measurement result. Figure 2E shown.
[0186] 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.
[0187] In some embodiments, the second measurement result still satisfies the first condition, and the first information sent by the terminal 101 still includes the first measurement result obtained previously.
[0188] 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.
[0189] In some embodiments, if the second measurement result does not satisfy the first condition, the terminal 101 may not send the first information.
[0190] In some embodiments, the second measurement result does not satisfy the first condition, and the terminal 101 still sends the first information, and the first information includes the second measurement result.
[0191] In some embodiments, the second measurement result does not satisfy the first condition, and the terminal 101 still sends the first information, and the first information includes the first measurement result.
[0192] In some embodiments, the sum of the first time and the second time may be referred to as a delay of L1 reporting.

[0243] In some embodiments, the above method may include the above method of embodiments of the communication system side, terminal side, network device side, etc., which will not be repeated here.
[0244] In this implementation mode or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementation modes or other examples.
[0245] The following is an exemplary introduction to the above methods in the above embodiments.
[0246] In the embodiment of the present application, for the event-triggered L1 report, the overall timeline mainly includes two parts, which can be as follows: Figure 2B As shown:
[0247] T1 (i.e., the first time in the aforementioned embodiments), the measurement time required for the multi-beam;
[0248] T2 (ie, the second time in the aforementioned embodiments) is the UL resource waiting time.
[0249] After T1, the terminal 101 can obtain the L1-RSRP measurement results of multiple beams (i.e., the first measurement results in the aforementioned embodiments) to evaluate whether the L1 reporting criteria (i.e., the first condition in the aforementioned embodiments) are met. If met, the terminal 101 will trigger the L1 report (the L1 report is also the first information in the aforementioned embodiments). The terminal 101 will request UL resources (i.e., the first request in the aforementioned embodiments), and then when the first UL resource that can carry the L1 report (i.e., the PUSCH in the aforementioned embodiments) arrives, the terminal 101 can send the L1 report to the network device 102.
[0250] In some embodiments, the duration of the UL resource waiting time (i.e., the second time in the aforementioned embodiments) is defined as follows:
[0251] The starting point of the UL resource waiting time (ie, the second time) can be defined as when the terminal 101 completes all measurements on the candidate beams and / or the current beam that meet the L1 event triggering conditions and starts to trigger the L1 report.
[0252] The end point of the UL resource waiting time (ie, the second time) may be defined as the first available UL resource (firstavailable UL resource).
[0253] In some embodiments, there are two types of UL resource configurations, which can be as follows: Figure 2C and 2D As shown:
[0254] For mode A, if Figure 2C As shown, there are 3 steps in total. The terminal 101 will send PUCCH (i.e., the first UL channel) at Ta to request UL resources (i.e., send the first request in the above embodiments). Then, the terminal 101 will wait for DCI at Tb. In step 3, the terminal 101 will send L1 report at Tc, where the UL resources in the second UL channel for carrying L1 report (i.e., PUSCH in the above embodiments) are dynamically scheduled by the network device 102.
[0255] For mode B, if Figure 2D As shown, there are two steps. In the first step, the terminal 101 will send a PUCCH (that is, the first UL channel) at Ta to request UL resources (that is, send the first request in the aforementioned embodiments), and in step 2, the terminal 101 will send an L1 report at Tb. Among them, the UL resource carrying the L1 report (that is, the PUSCH in the aforementioned embodiments) is the first available transmission opportunity of the second UL channel X symbols after the last symbol of the report notification sent on the PUCCH channel. This means that there will be a minimum gap between the first PUCCH channel and the second UL channel carrying the L1 report, that is, X symbols. X symbols are left for the network device 102 to decode the PUCCH.
[0256] Therefore, further, in some embodiments, there are two possible definitions for the "first available UL resource".
[0257] There are two ways to define the endpoint of the first UL resource:
[0258] The first method: the first PUCCH (that is, the PUCCH sending the first request in the aforementioned embodiments);
[0259] The second method: the first available transmission opportunity of the second UL channel (ie, the PUSCH for sending the first information in the aforementioned embodiments).
[0260] In some embodiments, L1 measurement is much faster due to the short RS cycle. Depending on the different configurations of L1 measurement cycle and UL resource availability, the L1 measurement cycle may be shorter than the UL resource waiting time. Then, terminal 101 may obtain several new L1-RSRP results (i.e., the second measurement results in the aforementioned embodiments) before the first UL resource is available, such as Figure 2E shown.
[0261] If the terminal 101 obtains several new L1 results (i.e., the second measurement results in the aforementioned embodiments) after triggering the L1 report, there are several issues: which L1 result will be included in the L1 report if the event triggering criteria still apply; what will happen if the new L1 result changes and no longer meets the event triggering criteria.
[0262] Therefore, the influence of the UL resource waiting time (second time) on the L1 event triggering report needs to be considered. In the case where the L1 measurement period is shorter than the first UL resource waiting time, at least one of the following solutions can be adopted.
[0263] For the new L1 result (second measurement result) obtained during the UL resource waiting time (i.e., within the second time):
[0264] In some embodiments, if the new L1 result still satisfies the event triggering condition, the terminal 101 may perform at least one of the following:
[0265] 1. Report the latest L1 result obtained during the UL resource waiting time (i.e., the second measurement result in the aforementioned embodiments);
[0266] 2. Report the L1 result obtained within the measurement time before the UL resource waiting time (i.e., the first measurement result in the aforementioned embodiments);
[0267] 3. The results included in the report are determined based on the UE implementation.
[0268] In some embodiments, if the new L1 result does not meet the event triggering condition, the terminal 101 may perform at least one of the following:
[0269] 1. Terminal 101 does not send L1 report;
[0270] 2. The terminal 101 still sends an L1 report, in which the result is the latest result of L1-RSRP and / or beam index or cell index (i.e., the second measurement result in the aforementioned embodiments);
[0271] 3. The terminal 101 will send an L1 report, but the result is not the latest result. The result in the report is the measurement result obtained before the measurement time and the UL resource waiting time (ie, the first measurement result in the above embodiments).
[0272] In some embodiments, the methods described in the above embodiments may be applicable to L1 reporting in beam management.
[0273] In some embodiments, the methods described in the above embodiments are also applicable to L1 / L2 triggered mobility (L1 / L2 triggered mobility, LTM) event-triggered L1 reporting. For LTM, the UE will need to measure the L1-RSRP of different cells.
[0274] For LTM's L1-RSRP report, the starting point of the UL resource waiting time can be defined as when the UE completes all measurements of candidate cells and / or current cells that meet the L1 event triggering conditions and will start triggering L1 reporting.
[0275] For LTM's L1-RSRP report, the end point of the UL resource waiting time can be defined as the first available UL resource carrying the L1 report.
[0276] In some embodiments, a new L1-RSRP measurement is provided for the UL resource waiting period, similar to the L1 reporting for beam management.
[0277] The embodiments of the present disclosure also propose a device for implementing any of the above methods, for example, a device is proposed, the above device includes a unit or module for implementing each step performed by the terminal in any of the above methods. For another example, another device is also proposed, including a unit or module for implementing each step performed by a network device (such as an access network device, a core network function node, a core network device, etc.) in any of the above methods.
[0278] It should be understood that the division of the units or modules in the above device is only a division of logical functions, and in actual implementation, they can be fully or partially integrated into one physical entity, or they can be physically separated. In addition, the units or modules in the device can be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and instructions are stored in the memory. The processor calls the instructions stored in the memory to implement any of the above methods or implement the functions of the units or modules of the above device, wherein the processor is, for example, a general-purpose processor, such as a central processing unit (CPU) or a microprocessor, and the memory is a memory inside the device or a memory outside the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits, and the functions of some or all of the units or modules can be realized by designing the hardware circuits. The above hardware circuits can be understood as one or more processors; for example, in one implementation, the above hardware circuit is an application-specific integrated circuit (ASIC), and the functions of some or all of the above units or modules are realized by designing the logical relationship of the components in the circuit; for example, in another implementation, the above hardware circuit can be realized by a programmable logic device (PLD), taking a field programmable gate array (FPGA) as an example, which can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by a configuration file, so as to realize the functions of some or all of the above units or modules. All units or modules of the above devices can be realized in the form of a processor calling software, or in the form of a hardware circuit, or in part by a processor calling software, and the rest by a hardware circuit.
[0279] In the disclosed embodiment, the processor is a circuit with signal processing capability. In one implementation, the processor may be a circuit with instruction reading and running capability, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which may be understood as a microprocessor), or a digital signal processor (DSP), etc.; in another implementation, the processor may realize certain functions through the logical relationship of the hardware circuit, and the logical relationship of the above hardware circuit is fixed or reconfigurable, such as a hardware circuit implemented by a processor as an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA.
