[0103] like Figure 1 As shown, the communication system 100 includes a terminal 101 and a network device 102 .

[0107] 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.

[0108] 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.

[0109] 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. Figure 1 The various entities shown are examples, and the communication system may include Figure 1 All or part of the subject, and may also include Figure 1 The number and form of other entities are arbitrary, each entity can be physical or virtual, the connection relationship between the entities is illustrative, the entities can be connected or disconnected, the connection can be in any way, it can be direct or indirect, and it can be wired or wireless.

[0110] The embodiments of the present disclosure may 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 (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine-to-Machine (M2M) system, Internet of Things (IoT) system, Narrow Band-IoT (NB-IoT) system, Vehicle-to-Everything (V2X), systems using other communication methods, next-generation systems based on them, etc. In addition, multiple systems can also be combined (for example, a combination of LTE or LTE-A and 5G, etc.) for application.

[0111] 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.

[0112] 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.

[0113] In some embodiments, the L1-RSRP measurement and reporting process may include but is not limited to the following steps:

[0114] Beam scanning: The base station (gNB) sends reference signals in all directions (beam scanning);

[0115] Measurement: The UE measures the received power of these reference signals (L1-RSRP);

[0116] Reporting: The UE reports the L1-RSRP measurement value back to the gNB;

[0117] Beam selection: The gNB analyzes the L1-RSRP report and selects the beam direction with the highest received power for communication.

[0118] 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.

[0119] The uplink communication method and device provided by the present disclosure are described in detail below with reference to the accompanying drawings.

[0120] 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:

[0121] Step S2101: Terminal 101 determines that a first event occurs and obtains a first measurement result.

[0122] In some embodiments, the terminal 101 measures at least one received reference signal (RS) to obtain the above-mentioned first measurement result.

[0123] 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.

[0124] In some embodiments, the L1 report of the terminal 101 is triggered by the first event.

[0125] As an example, the first event triggered above may include at least one of the following:

[0126] At least one new beam has a better quality (e.g. L1-RSRP) than the current beam.

[0127] The quality of the current beam is lower than the preset threshold;

[0128] The quality (eg, L1-RSRP) of at least one new beam is better than the RS obtained from an active Transmission Configuration Indication (TCI) state with the Mth best quality.

[0129] The above-mentioned M is the capability signaling of the subjective terminal 101 configured by Radio Resource Control (RRC).

[0130] Optionally, the terminal 101 may indicate only one candidate value or may not support the above event.

[0131] 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.

[0132] In some embodiments, the first time mentioned above is the time required for the terminal 101 to perform multi-beam or multi-cell measurement.

[0133] 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.

[0134] In some embodiments, the reference signal includes reference signals from at least two serving cells, and the reference signals from the respective serving cells correspond to different measurement periods, and the first time is the largest measurement period of the at least two measurement periods.

[0135] Among them, the Physical Cell Identifier (PCI) of each serving cell is different.

[0136] As an example, the first event is that the quality of at least one new beam (such as L1-RSRP) is better than that of the current beam. Assume that the current beam is from the serving cell and the new beam is from a cell with different PCI (CDP). The measurement periods of the two beams are different. As an example, Figure 2C As shown, 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 the L1 report is based on the maximum measurement period (i.e., T SSB_serving ) is confirmed.

[0137] It is understandable that if based on T SSB_CDP If the total measurement time is defined as one measurement cycle, since T SSB_CDP <T SSB_serving , when the terminal 101 obtains the L1-RSRP of the new beam, the terminal 101 does not yet obtain the L1-RSRP from the current beam, so the terminal 101 cannot compare with the standard and trigger the L1 report. Therefore, if multiple beams / cells need to be measured to compare with the standards defined in different events, the maximum measurement period in multiple beams or cells will be regarded as the total measurement time for triggering the L1 report.

[0138] In some embodiments, the number of measurement samples required to obtain the first measurement result (that is, the number of RSs required to be measured) is a first value. Figure 2D shown.

[0139] Optionally, the first value may be configured by the network device 102 or may be pre-agreed upon by a protocol.

[0140] Optionally, the first value may have a value range, which may be an L1 filter coefficient configured by the network device 102 or may be pre-agreed upon by a protocol.

[0141] As an example, it is assumed that N (ie, the first value) samples need to be measured, where N can be 1, 2, ..., n, where both N and n are positive integers.

[0142] In some embodiments, the first time is also related to the first value.

[0143] In some embodiments, the first time is determined based on a scaling factor Q.

[0144] In some embodiments, the first time is determined based on a conventional measurement period and the scaling factor Q.

[0145] Optionally, the value of the scaling factor Q is equal to the first value.

[0146] Optionally, the value of the scaling factor Q is equal to the minimum value in the value range of the first value. For example, if the value range of the first value is configured as 1, 2, ..., n, the value of the scaling factor Q is 1.

[0147] 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.

[0148] Evaluation period T at frequency 1 L1-RSRP_Measurement_Period_SSB (Evaluation periodT L1-RSRP_Measurement_Period_SSB for FR1)

[0149]

[0150] Evaluation period T at frequency 2 L1-RSRP_Measurement_Period_SSB (Evaluation periodT L1-RSRP_Measurement_Period_SSB for FR2)

[0151]

[0152] As an example, the evaluation time for beams from serving cells with different PCIs may be as follows:

[0153] Inter-cell L1-RSRP measurement period T for known cells with different PCIs at frequency 1 L1-RSRP_Measurement_Period_SSB_CDP (Inter-cell L1-RSRP measurement periodT L1-RSRP_Measurement_Period_SSB_CDP for known cells with different PCIs in FR1)

[0154]

[0155] Inter-cell L1-RSRP measurement period T for known cells with different PCIs at frequency 2 L1-RSRP_Measurement_Period_SSB_CDP (Inter-cell L1-RSRP measurement periodT L1-RSRP_Measurement_Period_SSB_CDP for known cells with different PCIs in FR2)

[0156]

[0157] Step S2102, the terminal 101 determines the L1-RSRP report.

[0158] In some embodiments, the terminal 101 determines that the first measurement result satisfies a first condition and determines to trigger L1-RSRP reporting.

[0159] In some embodiments, determining to trigger the L1-RSRP report means that the terminal 101 determines to send the above report to the network device 102 .

[0160] In some embodiments, after the first time, the terminal 101 can determine whether the obtained first measurement result meets the reporting criteria.

[0161] 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 L1-RSRP report is triggered.

[0162] 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 the terminal 101 starts to send the L1 report through the air interface.

[0163] It should be noted that the delay of the L1-RSRP report refers to the delay time of the L1-RSRP report.

[0164] In some embodiments, the starting point of the L1-RSRP report is: an event (ie, the first event) occurs when the beam / cell quality of the current beam / cell and / or other beams / cells has changed. From this point in time, the terminal 101 needs to evaluate the L1 report by measurement.

[0165] In some embodiments, the end point of the above L1-RSRP report is: the time when the terminal 101 starts sending the L1 report through the air interface.

[0166] In some embodiments, the delay of the L1-RSRP report is less than the first time.

[0167] In some embodiments, the delay of the L1-RSRP report is the sum of the first time and the second time.

[0168] The second time is the time interval between the moment of determining the report (ie, the moment of determining that the first measurement result satisfies the first condition) and the moment of sending the L1 report.

[0169] In some embodiments, terminal 101 sends the above L1-RSRP report after a second time.

[0170] In the embodiment of the present application, the terminal 101 cannot send the L1-RSRP report immediately after determining to send the L1-RSRP report, but needs to wait for uplink resources. The second time is the uplink resource waiting time (UL resource waiting time).

[0171] In some embodiments, the above-mentioned L1-RSRP report can be used for beam management.

[0172] In some embodiments, the first condition may include at least one of the following:

[0173] A first measurement result of at least one new beam is better than a first measurement result of a current beam;

[0174] The first measurement result of the current beam is lower than a preset threshold;

[0175] 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.

[0176] 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).

[0177] Optionally, the above-mentioned first event may also include other events that can trigger the measurement of LTM.

[0178] 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.

[0179] Step S2103, terminal 101 sends the above L1-RSRP report.

[0180] In some embodiments, after acquiring the uplink resource, the terminal 101 can send the above-mentioned L1-RSRP report on the uplink resource.

[0181] 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).

[0182] In some embodiments, 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. As an example, as shown in FIG2E.

[0183] 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.

[0184] 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.

[0185] 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.

[0186] In some embodiments, if the second measurement result does not satisfy the first condition, the terminal 101 may not send the first information.

[0187] 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.

[0188] 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.

[0189] In some embodiments, the sum of the first time and the second time may be referred to as a delay of L1 reporting.

[0224] The following is an exemplary introduction to the above methods in the above embodiments.

[0225] For L1 event-driven / UE-initiated reporting, the main motivation is to verify that when the beam or cell quality changes, the UE can detect the change in time and report L1-RSRP to the network within the required time according to different event triggering criteria.

[0226] In some embodiments, the event-triggered L1-RSRP report delay is defined as follows: the measurement report delay is defined as the time between the event that triggers the L1-RSRP measurement report (i.e., the first event in the aforementioned embodiments) and the time when the UE starts sending the L1-RRSP measurement report over the air interface.

[0227] In some embodiments, the start and end points of the L1 report are as follows:

[0228] The starting point of L1 reporting is the event that the beam / cell quality of the current beam / cell or other beam / cells has changed (ie the first event in the aforementioned embodiments). From then on, the UE needs to evaluate the L1 report by measurement.

[0229] The end point of L1 reporting is the time when the UE starts sending L1 reports over the air interface.

[0230] 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:

[0231] T1 (i.e., the first time in the aforementioned embodiments), the measurement time required for the multi-beam;

[0232] T2 (ie, the second time in the aforementioned embodiments) is the UL resource waiting time.

[0233] 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.

[0234] In some embodiments, the total delay length may be defined with or without considering the UL resource waiting time:

[0235] First, the total L1 reporting delay will be less than the measurement time required for multiple beams / cells (i.e., the first time in each of the aforementioned embodiments);

[0236] The second type: the total L1 reporting delay includes the measurement time required for multiple beams / cells (ie, the first time in the aforementioned embodiments) and the delay caused by the UL resource waiting time (ie, the second time in the aforementioned embodiments).

[0237] As an example, the trigger event (i.e., the first event in the aforementioned embodiments) may include at least one of the following:

[0238] Event 2: The quality (e.g., L1-RSRP) of at least one new beam is better than that of the current beam;

[0239] Event 1: The quality of the current beam is lower than the preset threshold;

[0240] Event 7: 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.

[0241] The above-mentioned M is the capability signaling of the subjective terminal 101 configured by Radio Resource Control (RRC).

[0242] Optionally, the terminal 101 may indicate only one candidate value or may not support the above event.

[0243] Taking event 2 as an example, assume that the current beam comes from the serving cell and the new beam comes from a cell with a different physical cell identifier (PCI). The measurement periods of the two beams are different. As an example, Figure 2C As shown, 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 the L1 report is based on the maximum measurement period (i.e., T SSB_serving ) is confirmed.

[0244] If based on T SSB_CDP If the total measurement time is defined as one measurement cycle, since T SSB_CDP <T SSB_serving , when the terminal 101 obtains the L1-RSRP of the new beam, the terminal 101 does not yet obtain the L1-RSRP from the current beam, so the terminal 101 cannot compare with the standard and trigger the L1 report.

[0245] For event 1, the UE only measures the current beam, and the measurement time only needs to consider one beam.

[0246] For event 7, the UE needs to measure the beam with an activated TCI state, and the total measurement time also needs to consider the measurement period of multiple beams.

[0247] Therefore, the measurement time in the event-triggered L1 report (ie, the first time in the aforementioned embodiments) can be defined as:

[0248] If multiple beams / cells need to be measured to compare with the criteria defined in different events, the maximum measurement period among the multiple beams or cells shall be considered as the total measurement time to trigger L1 reporting.

[0249] In some embodiments, for event-triggered L1 reports, the impact of the physical layer trigger window also needs to be considered. The trigger window can be as follows: Figure 2D shown.

[0250] 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 that triggers the 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:

[0251] 1. N, i.e., the number of configured L1-RSRP measurement samples (the first value in the aforementioned embodiments);

[0252] 2. min(N), the minimum configurable value. That is, if the minimum configurable value of N is 1, then Q=1.

[0253] The measurement period of the current or candidate beam will be scaled by Q compared to the traditional measurement period.

[0254] 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.

[0255] Evaluation period T at frequency 1 L1-RSRP_Measurement_Period_SSB (Evaluation periodT L1-RSRP_Measurement_Period_SSB for FR1)

[0256]

[0257]

[0258] Evaluation period T at frequency 2 L1-RSRP_Measurement_Period_SSB (Evaluation periodT L1-RSRP_Measurement_Period_SSB for FR2)

[0259]

[0260] As an example, the evaluation time for beams from serving cells with different PCIs may be as follows:

[0261] Inter-cell L1-RSRP measurement period T for known cells with different PCIs at frequency 1 L1-RSRP_Measurement_Period_SSB_CDP (Inter-cell L1-RSRP measurement periodT L1-RSRP_Measurement_Period_SSB_CDP for known cells with different PCIs in FR1)

[0262]

[0263] Inter-cell L1-RSRP measurement period T for known cells with different PCIs at frequency 2 L1-RSRP_Measurement_Period_SSB_CDP (Inter-cell L1-RSRP measurement periodT L1-RSRP_Measurement_Period_SSB_CDP for known cells with different PCIs in FR2)

[0264]
