[0040] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0041] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0042] In the related art, the activation of unknown secondary cells in the carrier aggregation scenario involves many processes, resulting in a long activation delay. How to reduce the activation delay of unknown secondary cells in the carrier aggregation scenario is an important issue.

[0043] Figure 1The flowchart of some embodiments of the secondary cell activation method disclosed in the present invention is performed by a terminal, which may also be referred to as UE (user equipment). A terminal is a device with wireless transceiver functions, which can communicate with one or more CNs (core networks) via access network devices in (R)AN ((radio) access network). It can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can also be deployed on the water, such as on a ship; it can also be deployed in the air, such as on an airplane, balloon or satellite. The terminal device can be a mobile phone, a tablet computer, a computer with wireless transceiver function, VR (virtual reality) terminal device, AR (augmented reality) terminal device, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, etc.

[0044] In step 110, after receiving the secondary cell activation signaling, the measurement result of the secondary cell is reported to a network side device, such as a base station.

[0045] In some embodiments, the measurement result is a valid measurement result, for example, a valid layer 3 measurement result, or a valid layer 3 measurement result and carrying an SSB (Synchronization Signal and PBCH block) index, or a valid layer 1 measurement result, or a valid layer 1 measurement result and carrying an SSB index.

[0046] In some embodiments, the measurement result includes RSRP (Reference Signal Received Power), or RSRQ (Reference Signal Received Quality), or SINR (Signal-to-noise and Interference Ratio).

[0047] Valid measurement results include measurement results that meet measurement indicator requirements, for example, RSRP, RSRQ or SINR that meet measurement indicator requirements defined by the standard. For example, RSRP, RSRQ or SINR is greater than a certain threshold.

[0048] In some embodiments, the measurement result is at least one of a SSB-based measurement report and a CSI-RS (Channel State Information-Reference Signal)-based measurement report.

[0049] In some embodiments, the terminal reports the measurement report within a certain time. The certain time is indicated by RRC (Radio Resource Control) signaling or MAC (Medium Access Control) signaling or DCI (Downlink Control Information). The certain time is a corresponding fixed or configurable time offset. For example, the certain time can be expressed as X milliseconds or X time slots relative to the moment when the terminal receives the MAC-CE (Control Element) measurement result report trigger indication or the secondary cell activation signaling. If the terminal fails to report the measurement result beyond this time, the terminal does not report the measurement result.

[0050] In some embodiments, there is no restriction on the time when the terminal reports the measurement report, that is, the terminal decides when to report the measurement report, that is, the time to report the measurement report depends on the terminal implementation.

[0051] In some embodiments, without limiting the time for the terminal to report the measurement report, the delay requirement corresponding to the subsequent process, such as the delay requirement corresponding to the uncertain delay of TCI (Transmission Configuration Indicator) can be defined as a time period, which is the time corresponding to the earlier report of the TCI configuration / activation time relative to the triggered measurement result report and the first valid L1-RSRP report in the original process, and the triggered measurement result report is, for example, a report corresponding to the reported layer 3 measurement result. It is decided by the network side device whether to configure TCI based on the report corresponding to the layer 3 measurement result reported after the secondary cell activation signaling, or based on the originally defined L1-RSRP report.

[0052] In some embodiments, the terminal reports the measurement result through RRC or MAC-CE or UCI (Uplink Control Information). The measurement result report meets the measurement report criteria defined in the current standard. The measurement result report is an event-triggered aperiodic report or a periodic report.

[0053] The terminal reports the measurement result of the secondary cell to the network side device through an RRC message, for example, through an RRCMeasurementReport message, and the measurement result includes a beam-level layer 3 measurement result and a beam index (SSB index).

[0054] In step 120, the activation process of layer 3 in the secondary cell activation process is skipped.

[0055] Skip the activation process of layer 3 in the secondary cell activation process, that is, do not execute the activation process of layer 3 in the secondary cell activation process. For example, the latency requirement of the secondary cell activation process does not include the latency requirement of layer 3. After the terminal reports the measurement result, it directly executes the layer 1 reference signal received power measurement and reporting process of the secondary cell activation process, and performs subsequent related processes, such as executing TCI state activation, fine time tracking and other processes, to complete the secondary cell activation.

[0056] In some embodiments, the terminal skips the activation process of the layer 3 part and the layer 1 measurement process in the secondary cell activation process. That is, the activation process of the layer 3 part and the layer 1 measurement process in the secondary cell activation process are not executed. For example, the delay requirement of the secondary cell activation process does not include the delay requirement of the layer 3 part and the delay requirement of the layer 1 measurement.

[0057] After the terminal reports the measurement result, the terminal does not execute the layer 3 related process and the layer 1 reference signal received power measurement process, and the terminal directly performs the subsequent related process to complete the secondary cell activation. For example, after the terminal reports the measurement result, the terminal does not execute the layer 3 related process and the layer 1 reference signal received power measurement process, and the terminal directly executes the layer 1 reference signal received power reporting process, which can be used for layer 1 reporting based on the aforementioned reported measurement results, and executes processes such as TCI state activation and fine time tracking.

[0058] In the above embodiment, after receiving the secondary cell activation signaling, the terminal reports the measurement result and skips the activation process of layer 3 in the secondary cell activation process, that is, executes the enhanced secondary cell activation process to complete the secondary cell activation process, thereby meeting the secondary cell activation requirements and reducing the activation delay.

[0059] Figure 2 It is a flowchart diagram of other embodiments of the secondary cell activation method disclosed in the present invention.

[0060] In step 210, before receiving the secondary cell activation signaling, the terminal obtains the measurement result of the secondary cell.

[0061] In some embodiments, within a period of time, the measurement of the secondary cell has been performed and the measurement result has been obtained, but the measurement result has not been reported to the network side device.

[0062] For example, before receiving the secondary cell activation signaling, the terminal has a valid measurement result carrying the SSB index, but does not report it to the network side device.

[0063] The performed measurement of the secondary cell is at least one of layer 3 measurement and layer 1 measurement of the secondary cell.

[0064] The period of time is a period of time defined by the standard, for example, a period of time corresponding to that defined by the TS 38.133 standard.

[0065] In step 220, after receiving the secondary cell activation signaling, the terminal reports the measurement result of the secondary cell to the network side device.

[0066] In some embodiments, the measurement result reporting of the secondary cell is triggered by a MAC-CE carried on the same MAC-CE as the secondary cell activation signaling, or carried on a MAC-CE different from the secondary cell activation signaling, or triggered by DCI signaling.

[0067] In the case where the measurement result report of the secondary cell is triggered by the MAC-CE carried on the same MAC-CE as the secondary cell activation signaling, the MAC-CE includes information for instructing the terminal to report the measurement report of the secondary cell. For example, the MAC-CE adds or does not add content. Adding content means adding a field in the original MAC-CE for indicating the terminal to report the content related to the measurement result, and the field is, for example, a new value. For example, the MAC CE may carry a report configuration number, or carry an indication of the measurement report performance. Not adding content means not adding a new value to the MAC-CE based on the original MAC-CE indicating the terminal to report the content related to the measurement result. After receiving the MAC-CE measurement result report trigger indication sent by the network side device, the terminal reports the measurement result.

[0068] The MAC-CE that is different from the secondary cell activation signaling, that is, a new MAC-CE is defined to trigger the reporting of the measurement result.

[0069] In some embodiments, after receiving the measurement configuration information for the terminal to report the measurement result sent by the network side device, the terminal reports the measurement result. For example, the measurement configuration information for the terminal to report the measurement result sent by the network side device through RRC signaling is received. The measurement configuration information includes the type of report (periodic or event triggered), the reported CGI (Cell Global Identifier, cell global identifier), the reference signal type used in the report, the reporting time interval, the measurement indicators (RSRP, RSRQ, SINR, etc.), and other contents.

[0070] In some embodiments, the measurement configuration information used by the terminal to report the measurement result is configured in the secondary cell adding signaling.

[0071] In some embodiments, the report of the measurement result is a report based on event triggering, and the event is a secondary cell activation event.

[0072] In some embodiments, the terminal reports a valid measurement result, such as an SSB index, an RSRP value, an RSRQ value, an SINR value, etc. The SSB remains detectable during activation of the secondary cell.

[0073] In some embodiments, if the terminal does not have a valid measurement result, it does not need to report the measurement result to the network side device, or the terminal reports a null value or other values. For example, other values ​​are RSRP_0, SS-RSRQ_0, SINR_0 or other possible values. RSRP_0, SS-RSRQ_0, and SINR_0 are specifically defined in the standard and will not be further elaborated here.

[0074] In step 230, the terminal skips the layer 3 activation procedure and the layer 1 measurement procedure in the secondary cell activation procedure.

[0075] In some embodiments, the terminal performs other possible enhanced operations, which depend on the terminal capabilities.

[0076] In some embodiments, the activation process of the layer three part includes, for example, an AGC (Automatic Gain Control) adjustment process, a cell search process, a time-frequency tracking process, and a beam information acquisition process.

[0077] In the above embodiment, the terminal executes an enhanced secondary cell activation process. By not executing the related processes of the layer 3 part and the layer 1 measurement process in the secondary cell activation process, the secondary cell activation process can be accelerated to achieve the purpose of reducing the delay. In addition, since the terminal has measured the secondary cell before the secondary cell activation signaling but has not had time to report the measurement results to the network, after receiving the secondary cell activation signaling, since there is no need to execute part of the activation process, the terminal can avoid repeated measurements, thereby reducing terminal resource overhead and energy consumption.

[0078] Figure 3 The flowchart of other embodiments of the secondary cell activation method disclosed in the present invention is shown in FIG. 1. The embodiment is applied to the scenario of activating an unknown secondary cell in carrier aggregation, and is aimed at the scenario of activating an unknown secondary cell in carrier aggregation of frequency range 1 or frequency range 2.

[0079] In step 310, before receiving the secondary cell activation signaling, the terminal has performed measurement of the secondary cell within a period of time defined by the standard and has a valid measurement result, but has not reported the measurement result to the network side device.

[0080] For example, for the FR1 frequency band, a period of time is the max(5*measCycleSCell, 5*DRX cycles) period before the terminal receives the secondary cell activation signaling, measCycleSCell is the secondary cell measurement period, and DRX cycles is the DRX (Discontinuous Reception) period.

[0081] For another example, for the FR2 frequency band, a period of time is equal to 4 seconds or 3 seconds before the terminal receives the last activation signaling of PDCCH (Physical Downlink Control Channel) TCI, (PDSCH (Physical DownLink Shared Channel) TCI (when applicable), and semi-persistent CSI-RS (when applicable) for CQI (Channel Quality Indicator) reporting. 4 seconds corresponds to the terminal supporting a power level of 1 / 5, and 3 seconds corresponds to the terminal supporting a power level of 2 / 3 / 4. And the terminal receives the secondary cell activation signaling no later than the terminal receives the MAC CE signaling of TCI activation.

[0082] In step 320, after receiving the secondary cell activation signaling, the terminal reports the measurement result of the valid secondary cell to the network side device.

[0083] The network side device sends measurement configuration information to the terminal for the terminal to report the measurement result. For example, the measurement report configured by the network is configured in the secondary cell addition signaling. Or an additional measurement reporting mechanism is configured and associated with the measurement configuration.

[0084] In some embodiments, the terminal reports the measurement results through RRC or MAC CE or UCI, and the measurement result report meets the measurement reporting criteria defined in the current standard. For example, the measurement indicators defined in the current TS 38.133 standard include measurement delay, measurement accuracy requirements, etc. More specifically, the measurement requirements of the inactivated secondary cell are met, as defined in Chapter 9 of TS 38.133, Tables 9.2.5.2-3 and 9.2.5.2-4, which are applicable to FR1 band and FR2 band respectively, and the accuracy requirements are met, as defined in Chapter 10 of TS 38.133.

[0085] In some embodiments, the reporting of measurement results is limited to a certain time, or there is no time limit for terminal reporting. If there is no time limit for terminal reporting, that is, it depends on the terminal implementation, then the delay requirement corresponding to the subsequent process, for example, the delay requirement corresponding to the uncertain delay of TCI can be defined as a time period, which is the time corresponding to the earlier report of the TCI configuration / activation time relative to the triggered measurement result report and the first valid L1-RSRP report in the original process. The triggered measurement result report is, for example, a report corresponding to the reported layer 3 measurement result. It is decided by the network side device implementation whether to configure TCI based on the report corresponding to the layer 3 measurement result reported after the secondary cell activation signaling, or based on the originally defined L1-RSRP report.

[0086] In step 330, the delay requirement of the secondary cell activation procedure to be executed does not include the delay requirement of the layer 3 part and the delay requirement of the layer 1 measurement.

[0087] For example, when a valid measurement result, such as a layer 3 measurement result and carrying an SSB index, is reported after the secondary cell activation signaling, and the terminal reports the layer 1 measurement according to the original secondary cell activation process before the network configures TCI for the terminal, the activation delay requirement is adjusted to: The delay requirement of the layer 3 part of the standard does not include T FirstSSB_MAX +15*T SMTC_MAX +8*T rs , where T FirstSSB_MAX The time when the first complete SSB burst set indicated by SMTC ends, or within 5ms when SMTC is not configured. SMTC_MAX is the longer SMTC cycle among multiple cells or the SMTC cycle of the activated secondary cell. rsThe SMTC period of the activated secondary cell or the SMTC period configured in the high-level parameters. For specific delay definitions, refer to the standard TS 38.133. Or the AGC adjustment part T defined in the standard FirstSSB_MAX +15*T SMTC_MAX Removed, cell search / measurement part 8*T rs Removed or left unchanged or combined with other enhancement operations such as reducing the beam scanning coefficient to an integer less than 8.

[0088] For another example, when a valid measurement result, such as a layer 3 measurement result and carrying an SSB index, is reported after the secondary cell activation signaling, the terminal skips the layer 3 related process and the layer 1 reference signal received power measurement process in the secondary cell activation process, and the terminal directly executes the layer 1 reference signal received power reporting process, and can use the aforementioned reported layer 3 measurement result for layer 1 reporting, and execute processes such as TCI state activation and fine time tracking. The network side device configures TCI based on the report of the layer 3 measurement result, which is earlier than the report corresponding to the layer 1 reference signal received power measurement reported by the terminal according to the original secondary cell activation process, and the activation delay requirement is adjusted to: the delay requirement of the layer 3 part in the standard does not include T FirstSSB_MAX +15*T SMTC_MAX +8*T rs The latency requirement for layer 1 measurement does not include T L1-RSRP,measure , where T L1-RSRP,measure Measure latency for L1-RSRP.

[0089] In some embodiments, reported layer 3 measurements are used for layer 1 reporting.

[0090] In the above embodiment, in order to address the problem of long activation time for unknown secondary cells in carrier aggregation in frequency range 1 or frequency range 2, the terminal in this embodiment has a valid measurement result and carries an SSB index before receiving the secondary cell activation signaling, and does not report to the network. After receiving the secondary cell activation signaling, the terminal reports the measurement result. After reporting the measurement result, the terminal does not execute the layer 3 related processes and the layer 1 measurement process in the secondary cell activation process. On the one hand, it can speed up the secondary cell activation process to achieve the purpose of reducing latency. On the other hand, it can avoid repeated measurements by the terminal, thereby reducing terminal resource overhead and energy consumption.

[0091] Figure 4 4 is a schematic diagram of the structure of some embodiments of the terminal disclosed herein, where the terminal includes a result reporting unit 410 and a process execution unit 420 .

[0092] The result reporting unit 410 is configured to report the measurement result of the secondary cell to the network side device after receiving the secondary cell activation signaling.

[0093] For example, the result reporting unit 410 reports the measurement result through RRC signaling, MAC-CE, or UCI.

[0094] In some embodiments, the measurement result includes a layer 3 measurement result, or a layer 3 measurement result and carrying the same SSB index, or a layer 1 measurement result, or a layer 1 measurement result and carrying the SSB index. The measurement result includes RSRP, or RSRQ, or SINR.

[0095] The measurement result is at least one of an SSB-based measurement report and a CSI-RS-based measurement report.

[0096] The measurement result report of the secondary cell is triggered by a MAC-CE carried by the same MAC-CE as the secondary cell activation signaling, or by a MAC-CE carried by a MAC-CE different from the secondary cell activation signaling, or by downlink control information DCI signaling. In the case where the measurement result report of the secondary cell is triggered by a MAC-CE carried by the same MAC-CE as the secondary cell activation signaling, the MAC-CE includes information for instructing the terminal to report the measurement report of the secondary cell.

[0097] The report of the measurement result is a report based on event triggering. For example, the event is a secondary cell activation event.

[0098] In some embodiments, Figure 5 As shown, the terminal further includes an information acquisition unit 510, which is configured to acquire the measurement result of the secondary cell before receiving the secondary cell activation signaling.

[0099] For example, within a period of time, the terminal has performed measurement of the secondary cell and obtained the measurement result, but has not reported the measurement result to the network side device. Performing measurement of the secondary cell includes: performing at least one of layer 3 measurement and layer 1 measurement of the secondary cell.

[0100] In some embodiments, the information acquisition unit 510 is further configured to receive measurement configuration information sent by the network side device for the terminal to report the measurement result. For example, the measurement configuration information sent by the network side device through RRC signaling for the terminal to report the measurement result is received.

[0101] The process execution unit 420 is configured to skip the activation process of layer 3 in the secondary cell activation process.

[0102] For example, the latency requirement of the secondary cell activation procedure does not include the latency requirement of the layer 3 part.

[0103] In some embodiments, the process execution unit 420 is further configured to skip the layer 1 measurement process in the secondary cell activation process.

[0104] For example, the latency requirement of the secondary cell activation procedure does not include the latency requirement of layer 1 measurement.

[0105] In the above embodiment, after receiving the secondary cell activation signaling, the terminal reports the measurement result and skips the activation process of layer 3 in the secondary cell activation process, that is, executes the enhanced secondary cell activation process to complete the secondary cell activation process, thereby meeting the secondary cell activation requirements and reducing the activation delay.

The memory 610 may be a disk, a flash memory or any other non-volatile storage medium. The memory is used to store the instructions in the above embodiments. The processor 620 is coupled to the memory 610 and may be implemented as one or more integrated circuits, such as a microprocessor or a microcontroller. The processor 620 is used to execute the instructions stored in the memory.

[0107] In some embodiments, the processor 620 is coupled to the memory 610 via a BUS 630.
