[0034] To facilitate understanding of the technical solutions of the embodiments of this application, the relevant technologies of the embodiments of this application are described below. The following relevant technologies are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and they all fall within the protection scope of the embodiments of this application.

[0035] 1. Carrier Aggregation (CA)

[0036] To meet the demands of high speeds, 5G supports CA (Carrier Aggregation) technology. CA enables NR systems to support greater bandwidth and achieve higher peak data rates by jointly scheduling and utilizing resources on multiple component carriers (CCs). Based on the continuity of the aggregated carriers in the spectrum, it can be divided into continuous carrier aggregation and discontinuous carrier aggregation; based on whether the aggregated carriers are in the same frequency band, it can be divided into intra-band carrier aggregation and inter-band carrier aggregation.

[0037] In a CA (Cellular Component), there is one and only one primary cell component (PCC), and there may be one or more secondary cell components (SCCs). The PCC provides Radio Resource Control (RRC) signaling connections, Non-Access Stratum (NAS) functions, security functions, etc. The SCC only provides additional radio resources. The PCC and SCC are collectively referred to as the Serving Cell, where cells on the PCC are primary cells (PCells), and cells on the SCC are secondary cells (SCells).

[0038] 2. Dual Connectivity (DC)

[0039] The DC architecture consists of one master node (MN) and one secondary node (SN). The cell group on the MN side is called the master cell group (MCG), and the cell group on the SN side is called the secondary cell group (SCG). MCG and SCG are collectively referred to as serving cells. MCG includes one master cell (PCell) and may also include one or more secondary cells (SCell), while SCG includes one or more secondary cells (SCell).

[0040] The DC architecture can be extended to a multi-connectivity (MC) architecture. In a DC architecture, there is one MN and one SN. In an MC architecture, there is one MN and multiple SNs.

[0041] To facilitate understanding of the technical solutions of the embodiments of this application, the technical solutions of this application are described in detail below through specific embodiments. The above-mentioned related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0042] Figure 2 This is a flowchart illustrating the cell activation method provided in the embodiments of this application. Figure 1 ,like Figure 2 As shown, the cell activation method includes some or all of the following:

[0043] Step 201: The terminal activates the secondary cell.

[0044] In some implementations, a secondary cell (SCell) can also be described as a secondary carrier.

[0045] In some implementations, the activation of a secondary cell by the terminal can also be described as the terminal activating a secondary cell, or as the terminal activating a deactivated secondary cell, or as the terminal activating a deactivated secondary cell. Here, a deactivated secondary cell refers to a secondary cell that is in a deactivated state.

[0046] In some implementations, activation delay can also be described as activation time.

[0047] In some implementations, the activation delay is the first time, and can also be described as: activation is completed within the first time; or as: the activation delay does not exceed the first time; or as: the secondary cell activation delay is the first time. The first time is a period of time, measured in milliseconds.

[0048] In some implementations, the secondary cells mentioned above include known secondary cells (or described as secondary cells being known) and unknown secondary cells (or described as secondary cells being unknown). A secondary cell may belong to FR1 (Frequency Range 1) or FR2 (Frequency Range 2).

[0049] In some implementations, the secondary cell is a known cell if one or more of the following conditions are met, or the terminal determines that the secondary cell is a known cell if one or more of the following conditions are met:

[0050] 1) The terminal sends the first report;

[0051] 2) The terminal sends the first report within the second time period before receiving the secondary cell activation command;

[0052] 3) The terminal sends the first report within a second time period before receiving the secondary cell activation command, and the Synchronization Signal / PBCH Block (or described as Synchronization Signal Block, abbreviated as SSB) remains detectable;

[0053] 4) The SSB remains detectable during the third time period of the secondary cell activation process;

[0054] 5) The terminal sends a first report carrying the SSB index;

[0055] 6) The secondary cell activation command is received after the Reference Signal Received Power (RSRP) is reported, and the secondary cell activation command is received no later than the Transmission Configuration Indicator (TCI) activation command; the TCI activation command can also be described as the TCI state activation command.

[0056] 7) During the period from the RSRP reporting time to the effective Channel Quality Indicator (CQI) reporting time, the SSB carrying the index reported by the terminal remains detectable.

[0057] In some implementations, the secondary cell is a known cell, or alternatively, the secondary cell is known.

[0058] It should be noted that the first report sent by the terminal is a report for the secondary cell, or in other words, the first report includes reports for the secondary cell.

[0059] In some implementations, the first report includes a measurement report and / or a first result.

[0060] In some implementations, the first report / first result in the first report includes at least one of the following: idle measurement result, deactivated measurement result, measurement result for carrier aggregation or dual connectivity (CA / DA) establishment, measurement result for fast carrier aggregation or dual connectivity (CA / DA) establishment, measurement result for carrier aggregation or dual connectivity (CA / DA) establishment in idle mode, measurement result for carrier aggregation or dual connectivity (CA / DA) establishment in deactivated mode, measurement result for fast carrier aggregation or dual connectivity (CA / DA) establishment in idle mode, and measurement result for fast carrier aggregation or dual connectivity (CA / DA) establishment in deactivated mode.

[0061] In some implementations, the measurement results in the first report / first result include layer 1 (L1) measurement results and / or layer 3 (L3) measurement results. For example, the L1 measurement results are the L1-RSRP measurement results, and the L3 measurement results are the L3-RSRP measurement results.

[0062] In some implementations, the measurement results in the first report / first result are valid if one or more of the following conditions are met:

[0063] 1) The measurement results were obtained in the fourth time period before the MSG1 transmission;

[0064] 2) The measurement results meet the measurement accuracy requirements, or the measurement results at the measurement time meet the measurement accuracy requirements.

[0065] Here, MSG1 is the first message in the random access process, and MSG1 contains a premble.

[0066] In some implementations, the measurement report in the first report / first report includes at least one of the following: an L3 measurement report (e.g., an L3-RSRP measurement report) and an L1 measurement report (e.g., an L1-RSRP measurement report). Here, the measurement report includes an advance measurement report, which includes a measurement report for CA / DC establishment, a measurement report for fast CA / DC establishment, a measurement report for CA / DC establishment in idle mode, a measurement report for CA / DC establishment in deactivation mode, a measurement report for fast CA / DC establishment in idle mode, and a measurement report for fast CA / DC establishment in deactivation mode.

[0067] It should be noted that SSB remaining detectable means that the SSB remains detectable within the secondary cell or the cell group to which the secondary cell belongs. SSB remaining detectable can be understood as the SSB signal level being above a certain threshold, allowing it to be detected by the terminal. If the SSB signal level is too low, it will be submerged in interference and / or noise and cannot be identified and detected by the terminal.

[0068] It should be noted that the receiving time of the secondary cell activation command refers to the moment when the terminal receives the secondary cell activation command. The secondary cell activation command is used to trigger the activation of the secondary cell.

[0069] It should be noted that the RSRP reporting time refers to the time when the terminal reports the RSRP.

[0070] It should be noted that the TCI activation command reception time refers to the moment when the terminal receives the TCI activation command. The TCI activation command is used to trigger the activation of the TCI state.

[0071] It should be noted that the CQI reporting time refers to the time when the terminal reports the CQI.

[0072] In some implementations, the secondary cell activation delay is a first time, which is related to at least one of the following: Media Access Control (MAC) Control Element (CE) feedback time, SSB-based Measurement Timing Configuration (SMTC) period, Channel State Information-Reference Signal (CSI-RS) period, the end time of the first complete SSB burst, the time between the terminal completing the processing of the activation command and the first available SSB, and L1 measurement time.

[0073] In some implementations, the secondary cell activation delay is a first time, which includes at least one of the following: MAC CE feedback time, SMTC cycle, CSI-RS cycle, the end time of the first complete SSB burst, the time between the terminal completing the processing of the activation command and the first available SSB, and L1 measurement time.

[0074] In some implementations, the MAC CE feedback time refers to the time between the moment the terminal receives the MAC CE and the moment the terminal responds with the corresponding ACK / NACK information. For example, the MAC CE feedback time is 3ms.

[0075] In some implementations, the SMTC period is the SMTC period of the active secondary cell; or, the SMTC period is the SMTC period configured in the measurement target (measObjectNR); or, if the terminal is not provided with an SMTC, the SMTC period is 5 milliseconds.

[0076] In some implementations, the CSI-RS cycle can also be described as a CSI-RS burst cycle.

[0077] In some implementations, the end time of the first complete SSB burst can also be described as: the time until the end of the first complete SSB burst; or as: the time until the end of the first complete SSB burst indicated by the SMTC; or as: the time until the end of the first complete SSB burst indicated by the SMTC. The end of an SSB burst can also be described as the end of the SSB burst. An SSB burst consists of N SSBs, where N is an integer. The SSBs in an SSB burst are sent in a round-robin fashion, so an SSB burst can be understood as N SSBs within a certain period of time.

[0078] In one example, the end time of the first complete SSB is: (slot n + (HARQ time + 3 ms) / slot length) after the end of the first complete SSB burst; that is, this time starts from (slot n + (HARQ time + 3 ms) / slot length) and ends at the end of the first complete SSB burst.

[0079] In one example, if SMTC is not configured, the end time of the first complete SSB is within 5 milliseconds after (slot n + (HARQ time + 3 milliseconds) / slot length).

[0080] In one example, the end time of the first complete SSB is: (slot n + (HARQ time + 3 ms) / slot length) after the end of the first complete periodic CSI-RS burst; that is, this time starts from (slot n + (HARQ time + 3 ms) / slot length) and ends at the end of the first complete CSI-RS burst.

[0081] In the example above, the terminal receives the secondary cell activation command in time slot n.

[0082] In the example above, the HARQ time is the time between downlink data transmission and acknowledgment. Acknowledgment can be understood as feedback ACK / NACK.

[0083] In the example above, " / " represents division (or quotient division).

[0084] In some implementations, the time between the terminal completing the processing of the activation command and the first available SSB can also be described as: the time between the terminal completing the processing of the activation command and the first fully available SSB; or as: the time between the terminal completing the processing of the last activation command and the first available SSB. The last activation command can also be described as the latest activation command. It should be noted that since the terminal can receive multiple activation commands, this refers to the processing of the last activation command.

[0085] In some implementations, the L1 measurement time can also be described as the L1 measurement delay or the L1 measurement period. L1 measurements include L1-RSRP and L1-SINR. L1-RSRP includes SSB-based L1-RSRP and CSI-RS-based L1-RSRP. L1-SINR includes SSB-based L1-SINR and CSI-RS-based L1-SINR.

[0086] In some implementations, the secondary cell activation delay is the first time; among them,

[0087] 1) The first time should include at least the MAC CE feedback time;

[0088] 2) and / or, at least the SMTC period should be included in the first instance;

[0089] 3) and / or, the first time includes at least the end time of the first complete SSB burst;

[0090] 4) and / or, the first time includes at least the time between the terminal completing the processing of the activation command and the first available SSB;

[0091] 5) and / or, the first time period includes at least the SMTC cycle and the time between the terminal completing the processing of the activation command and the first available SSB; or, the first time period includes at least (SMTC cycle + the time between the terminal completing the processing of the activation command and the first available SSB).

[0092] 6) and / or, the first time includes at least the SMTC cycle and the end time of the first complete SSB burst; or, the first time includes at least (SMTC cycle + the end time of the first complete SSB burst).

[0093] 7) and / or, the first time includes at least the SMTC period and the end time of the first complete CSI-RS burst; or, the first time includes at least (SMTC period + end time of the first complete CSI-RS burst);

[0094] 8) and / or, first time = SMTC cycle + end time of the first complete SSB burst + 5 milliseconds;

[0095] 9) and / or, first time = SMTC period + end time of the first complete CSI-RS burst + 5 milliseconds;

[0096] 10) and / or, First time = SMTC cycle + end time of the first complete SSB burst + 5 milliseconds + L1-RSRP measurement time;

[0097] 11) and / or, First time = SMTC cycle + end time of the first complete CSI-RS burst + 5 milliseconds + L1-RSRP measurement time;

[0098] 12) and / or, first time = MAC CE feedback time;

[0099] 13) and / or, First time = MAC CE feedback time + L1 - RSRP measurement time.

[0100] In some implementations, if the first report includes measurements carrying an SSB index, then the first time period does not include the L1-RSRP measurement time; if the first report does not include measurements carrying an SSB index, then the first time period includes the L1-RSRP measurement time.

[0101] It should be noted that if the first timeframe includes the L1-RSRP measurement time, it means the terminal needs to perform L1-RSRP measurement during the secondary cell activation process; if the first timeframe does not include the L1-RSRP measurement time, it means the terminal does not need to perform L1-RSRP measurement during the secondary cell activation process. Similarly, for times included in the first timeframe, it means the operation corresponding to that time needs to be performed during the secondary cell activation process; for times not included in the first timeframe, it means the operation corresponding to that time does not need to be performed during the secondary cell activation process.

[0102] In some implementations, the terminal receives first information instructing it to activate a secondary cell, with the activation delay being a first time. The first information may be at least one of MAC CE, Downlink Control Information (DCI), and Radio Resource Control (RRC), or described as the first information being carried by at least one of MAC CE, DCI, and RRC. For example, the first information may be a secondary cell activation MAC CE, or described as the first information instructing the terminal to activate the secondary cell's MAC CE. Receiving the first information includes the terminal receiving first information sent by the network.

[0103] In some implementations, the secondary cell activation delay is first-time when at least one of the following conditions is met:

[0104] The terminal sends a measurement report within five hours before receiving the activation command;

[0105] SSB is detectable during the sixth time period.

[0106] In some implementations, the terminal sends a measurement report within a fifth time period before receiving the activation command; it can also be described as the terminal sending a measurement report within a fifth time period before receiving the activation command.

[0107] In some implementations, the activation command includes at least one of a secondary cell activation command and a TCI (or described as a TCIstate) activation command. The activation command can also be described as activating a MAC CE.

[0108] In some implementations, the above-mentioned sending of a measurement report can also be described as "a measurement report has been sent".

[0109] In some implementations, the terminal sends a measurement report within a fifth time period before receiving the activation command, including: if the secondary cell belongs to FR1 (or is described as an FR1 secondary cell), the terminal sends (or is described as having sent) a measurement report within a fifth time period before receiving the activation command.

[0110] In some implementations, the terminal sends a measurement report within a fifth time period before receiving the activation command, including: if the secondary cell belongs to FR2 (or is described as an FR2 secondary cell), the terminal sends (or is described as having sent) a measurement report within a fifth time period before receiving the latest activation command.

[0111] In some implementations, the terminal sends a measurement report within a fifth time period before receiving the activation command, including: if the secondary cell is FR2 (or described as an FR2 secondary cell), the terminal sends (or is described as having sent) a measurement report within a fifth time period before receiving the latest activation command for the PDCCH TCI, PDSCH TCI, and the semi-persistent CSI-RS for CQI reporting.

[0112] In some implementations, the fifth time can be 3 seconds, 4 seconds, or 5 seconds. For example, in the FR1 scenario, the fifth time is 5 seconds; in the FR2 scenario, for terminals that support power level 1 / 5 (power level 1 or power level 5), the fifth time is 4 seconds; in the FR2 scenario, for terminals that support power level 2 / 3 / 4 (power level 2, power level 3, or power level 4), the fifth time is 3 seconds.

[0113] In some implementations, the aforementioned latest activation command may also be described as the most recent activation command or the last activation command.

[0114] In some implementations, the fifth time period before the terminal receives the latest activation command of PDCCH TCI, PDSCH TCI, and semi-persistent CSI-RS for CQI reporting can be understood as the fifth time period preceding the last received activation command, starting from the activation command of PDCCH TCI, PDSCH TCI, and semi-persistent CSI-RS for CQI reporting.

[0115] The terminal sends a measurement report within five hours before receiving the activation command, indicating that the terminal has measured the cell and obtained the cell's synchronization and power information before receiving the activation command. Therefore, the relevant steps in the secondary cell activation time can be omitted, thereby reducing the secondary cell activation latency.

[0116] In some implementations, the measurement report includes a measurement report with an SSB index.

[0117] In some implementations, the aforementioned sixth time is the time from the earliest measurement to the end of the secondary cell activation time, or it can be described as the time from the earliest measurement to the valid CQI report. Here, sending a valid CQI report signifies that the secondary cell activation is complete.

[0118] In some implementations, the fact that the SSB is detectable during the sixth time period can be described as follows: the SSB is detectable from the earliest measurement to the end of the secondary cell activation time; or it can be described as follows: the SSB is detectable from the earliest measurement to the effective CQI reporting.

[0119] For example, the earliest measurement is the moment before MSG1 is sent. Specifically, the earliest measurement is the moment of the valid duration (or described as the validity period) before MSG1 is sent, or described as the moment of the valid duration before MSG1 is sent if a valid duration is configured (or described as the moment of the valid duration if the terminal is configured to have a valid duration). Specifically, the earliest measurement is the start time of a period of time (i.e., the valid duration) before MSG1 is sent, such as... Figure 4 As shown, T2 is the earliest measurement time.

[0120] It should be noted that the validity period is the time used to verify the reported measurement or, in other words, the time the terminal determines the validity of the reported measurement. The reported measurement includes at least one of the following: idle measurement, deactivated measurement, and reselection measurement. The validity period can be configured by the network. For example, the validity period can be 5 seconds, 10 seconds, 20 seconds, 50 seconds, 100 seconds, etc.

[0121] It should be noted that the earliest measurement is the moment the terminal obtains the configuration parameters. Specifically, if only the measurement duration is configured, the earliest measurement is the moment the terminal obtains the configuration parameters. Here, the measurement duration is the duration of idle and / or deactivation measurements.

[0122] In some implementations, the above-mentioned SSB is detectable, or it can be described as a measurable SSB that is detectable.

[0123] In some implementations, if the terminal supports measurement verification reporting and is configured with a valid duration, the secondary cell activation delay is the first time; or, if the terminal is not configured with a valid duration and the measurement duration has not expired, the secondary cell activation delay is the first time.

[0124] In some implementations, the aforementioned measurement verification reporting includes measurement verification and reporting based on EMR measurements and / or measurement verification based on reselection measurements. Specifically, measurement verification and reporting of EMR measurements refers to the verification and reporting of EMR measurements during the connection establishment / recovery process. Verification of reselection measurements includes verification and reporting of reselection measurements in the idle / deactivated state. Measurement verification reporting can be understood as checking the validity of measurement results and reporting valid measurement results.

[0125] Here, EMR stands for Early Measurement Report, and EMR is related to rapid CA / DC establishment.

[0126] In some implementations, the terminal supports measurement verification reporting and is configured with a valid duration including at least one of the following:

[0127] The terminal supports measurement verification and reporting based on EMR measurements, and is configured with the time for the UE to determine the validity of the reported idle / deactivation measurements;

[0128] The terminal supports measurement verification and reporting based on reselection measurements, and is configured with a time limit for the UE to determine the validity of the reported reselection measurements.

[0129] In some implementations, the first time / second time / third time / fourth time / fifth time / sixth time described in the above scheme can also be described as: first duration / second duration / third duration / fourth duration / fifth duration / sixth duration, or as: first period / second period / third period / fourth period / fifth period / sixth period.

[0130] In some implementations, one or more of the first time, second time, third time, fourth time, fifth time, and sixth time described in the above scheme may be protocol-defined or network-configured.

[0131] In some implementations, the first time described in the above scheme can be 3 milliseconds, 4 milliseconds, or 5 milliseconds; the first time can also be related to the DXR period and / or the secondary cell period (or described as the secondary cell measurement period, the length of which is related to the number of subframes, such as 160 subframes). For example, the first time is an integer multiple of the DXR period, or the first time is an integer multiple of the secondary cell period, or the first time is the maximum value of an integer multiple of the DXR period and an integer multiple of the secondary cell period, that is, the maximum value of the two.

[0132] In some implementations, the first information can be explicitly indicated by signaling, for example, by setting a value of 1 or TRUE to instruct the terminal to activate the deactivated cell using a known cell activation method.

[0133] In some implementations, the aforementioned first information may also be implicit, such as by instructing the terminal to perform a validity check (or described as a validity check of the measurement results, or described as measurement verification), such as configuring a validity time window (or described as a validity duration, i.e., measurement verification is performed within this period), or by instructing the terminal to report at least one of the following: idle mode measurement results, deactivation mode measurement results, measurement results for CA / DC establishment, measurement results for fast CA / DC establishment, idle mode CA / DC measurement results, and deactivation mode CA / DC measurement results, implicitly notifying the terminal that the activation time for activating the deactivation cell can be reduced (or described as fast secondary cell activation).

[0134] In some implementations, the terminal sends a second message indicating at least one of the following:

[0135] The terminal supports secondary cell activation latency as quickly as possible;

[0136] The terminal supports fast activation;

[0137] The terminal supports measurement and verification;

[0138] The terminal supports verification-based quick activation.

[0139] In some implementations, the sending of second information by the terminal can also be described as the terminal reporting second information. Sending second information includes the terminal sending second information to the network. Through this second information, the terminal notifies the network of supported capability information.

[0140] In some implementations, the above-mentioned fast activation can also be described as fast activation of the secondary cell, or as fast activation of the secondary cell.

[0141] In some implementations, the aforementioned indication that the terminal supports measurement verification is implicitly indicated. This can be understood as follows: if the terminal supports measurement verification, then the terminal supports fast activation. For example, the network is implicitly notified when the terminal reports support for validity checks (or describes it as a validity check of measurement results, or as measurement verification), or supports at least one of fast CA / DC, idle mode measurement, deactivation mode measurement, measurement for CA / DC establishment, measurement for fast CA / DC establishment, idle mode CA / DC measurement, and deactivation mode CA / DC measurement. That is, if the terminal supports the above operations, it implicitly indicates that the terminal supports a reduction in secondary cell activation time (or describes it as fast secondary cell activation). Here, the reduction in secondary cell activation time can also be described as an enhancement of secondary cell activation.

[0142] In some implementations, the above-mentioned verification-based approach can also be described as measurement-based verification, or measurement-based validity checking, or verification-based reporting, or measurement-based verification reporting. Verification-based approaches include measurement verification based on EMR measurements and measurement verification based on reselection measurements.

[0143] In the technical solution of this application embodiment, if the terminal has reported the measurement results within a certain period of time before receiving the secondary cell activation command, it means that the terminal has recently performed measurements on the target cell or frequency point. In this case, the terminal does not need to perform the AGC, synchronization, L1 measurement and other operations required for cell activation again. That is to say, the AGC (Automatic Gain Control), synchronization, L1 measurement and reporting links included in the cell latency of the prior art can be eliminated, thereby reducing the cell activation latency.

[0148] In some implementations, the secondary cell activation delay is the first time; among them,

[0154] 6) and / or, the first time includes at least the SMTC cycle and the end time of the first complete SSB burst; or, the first time includes at least (SMTC cycle + the end time of the first complete SSB burst).

[0155] 7) and / or, the first time includes at least the SMTC period and the end time of the first complete CSI-RS burst; or, the first time includes at least (SMTC period + end time of the first complete CSI-RS burst);

[0156] 8) and / or, first time = SMTC cycle + end time of the first complete SSB burst + 5 milliseconds;

[0157] 9) and / or, first time = SMTC period + end time of the first complete CSI-RS burst + 5 milliseconds;

[0160] 12) and / or, first time = MAC CE feedback time;

[0161] 13) and / or, First time = MAC CE feedback time + L1 - RSRP measurement time.

[0162] In some implementations, if the first report sent by the terminal includes a measurement carrying an SSB index, then the first time does not include the L1-RSRP measurement time; if the first report sent by the terminal does not include a measurement carrying an SSB index, then the first time includes the L1-RSRP measurement time.

[0165] The terminal supports fast activation;

[0166] The terminal supports measurement and verification;
