Activation method of secondary cell, terminal and network side device

[0001] Cross-reference to related applications

[0002] The present application claims priority to the Chinese patent application No. 202411094173.4, filed on August 9, 2024, and entitled "Activation method of secondary cell, terminal and network side device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application belongs to the field of communication technology, and specifically relates to an activation method of a secondary cell, a terminal and a network side device. BACKGROUND

[0004] In related technologies, when activating a secondary cell, it can be generally divided into two activation cases, such as a known cell case and an unknown cell case. Compared with the unknown cell activation case, the cell activation delay gain can be obtained for the cell activation in the known cell case. The cell activation delay refers to a period of time from when the terminal receives the secondary cell activation command to when the terminal transmits the valid channel state information (CSI) report.

[0005] However, for the secondary cell to be activated, there are still certain limitations when using the known cell judgment rule provided in related technologies to determine whether the secondary cell can apply the cell activation delay of the known cell for cell activation. For example, in some activation scenarios, the secondary cell to be activated that completes cell measurement cannot be determined as an unknown cell due to the limited size of the time window (such as the first detection window) for known cell judgment, which affects the activation efficiency of the secondary cell.

It can be understood that the above function modules can be network elements in a hardware device, can be software function modules running on a special hardware, or can be virtualized function modules instantiated on a platform (for example, a cloud platform).

[0042] In addition, in order to facilitate understanding, the related technologies mentioned in the technical solutions of the present application are explained as follows.

[0043] (1) Dual Connectivity (DC) / Carrier Aggregation (CA)

[0044] DC refers to providing resources of two network nodes (access network elements) for a terminal, one of which is called a master node (MN) and the other is called a secondary node (SN). In each network node, the carrier aggregation (CA) technology can be used to configure a series of serving cells (also called cell groups) controlled by the node for the terminal. The cell group controlled by the master node is the master cell group (MCG), and the cell group controlled by the secondary node is the secondary cell group (SCG). Each cell group contains a special cell (SpCell) and a series of secondary cells (Scell). The special cell in the MCG is called the primary cell (PCell), and the special cell in the SCG is called the primary secondary cell (PSCell). The SpCell uses the primary carrier in a cell group, and the other secondary cells use the secondary carrier, and the resource scheduling in a cell group is performed by the SpCell.

[0045] (2) Idle or Inactive State (idle / inactive) Measurement

[0046] The network side can instruct the terminal to perform measurement on the carrier that can be configured as DC or CA when in non-connected state (such as idle and inactive), and the terminal can indicate the available early measurement result to the network side during connection establishment / resumption or after entering the connected state, and then report the measurement result to the network side when the network side requests to report the early measurement result. The network can configure the terminal for early measurement through dedicated signaling (such as RRC Connection Release) or in system broadcast message (such as LTE SIB5 / 24, NR SIB4 / 11), such as the carrier to be measured, the cell list, the measurement duration, etc. Early measurement enables the network side to configure DC or CA for the terminal according to the measurement result reported by the terminal immediately after the terminal enters the connected state, effectively shortening the establishment delay of DC / CA.

[0047] (3) SCell activation

[0048] In CA, two or more component carriers (CCs) can be aggregated. A terminal can simultaneously receive or transmit on one or more CCs according to its capability. In the related art, two states are defined for a secondary cell, i.e., an activated state and a deactivated state. If a medium access control (MAC) entity is configured with one or more SCells, the network can activate and deactivate the configured SCells, and currently, the SCell can be activated / deactivated in any of the following modes 1-4.

[0049] Mode 1: The terminal receives a medium access control control element (MAC CE) command for SCell activation / deactivation.

[0050] Mode 2: The terminal receives an enhanced SCell activation / deactivation MAC CE command.

[0051] Mode 3: The SCell is configured with a sCell deactivation timer (DeactivationTimer), and when the timer expires, the related SCell is deactivated, and if there is data transmission, the timer is restarted.

[0052] Mode 4: If the radio resource control (RRC) layer is configured with sCellState, the SCell is in the activated state, otherwise the SCell is deactivated.

[0053] Based on the foregoing, in the related art, the SCell activation delay is from when the terminal receives the SCell activation command to when the terminal transmits a valid CSI report. The activation procedure can be divided into two cases, namely, the known cell case and the unknown cell case. Among them, taking the activation process of the deactivated cell as an example, the judgment conditions of the known cell include the following contents.

[0054] For the frequency range (FR) 1 deployment mode, the SCell satisfies the following conditions 1-condition 2 to be a known cell.

[0055] Condition 1: Within the time of max(5*measCycleSCell, 5*DRX cycles) before receiving the cell activation command, the following a)-b) is satisfied. Wherein, max(5*measCycleSCell, 5*DRX cycles) can be understood as: the maximum of 5*measCycleSCell and 5*DRX cycles, “measCycleSCell” represents the secondary cell measurement period, and “DRX cycles” represents the period of discontinuous reception.

[0056] a) The terminal has sent a valid measurement report of the SCell to be activated.

[0057] b) The measured SSB remains detectable according to the cell identification conditions specified in sections 9.2 and 9.3 of TS 38.133.

[0058] Condition 2: According to the cell identification conditions specified in sections 9.2 and 9.3 of TS 38.133, the SSB measured during the first detection window (the window length here is max(5*measCycleSCell, 5*DRX cycles)) in the past also remains detectable during the cell activation delay.

[0059] For the FR2 deployment mode, the SCell satisfies the following conditions 1-condition 2 to be a known cell.

[0060] Condition 1: Within the first detection window before the terminal receives the last activation command of the physical downlink control channel (PDCCH) transmission configuration indication (TCI), physical uplink shared channel (PDSCH) TCI (if applicable) and channel quality indicator (CQI) report semi-persistent channel state information reference signal (CSI-RS), perform the following a)-b) shown.

[0061] a) The terminal has sent a layer 3 (L3)-reference signal received power (RSRP) measurement report carrying the SSB index

[0062] b) After the L3-RSRP report, no later than the time the terminal receives the MAC CE TCI activation command, the SCell activation command is received.

[0063] Wherein, for terminals supporting power levels 1 / 5, the first detection window is 4s, and for terminals supporting power levels 2 / 3 / 4, the first detection window is 3s.

[0064] Condition 2: From the effective measurement result report to the effective CQI report, the reported SSB carrying the index remains detectable according to the cell identification conditions specified in sections 9.2 and 9.3 of TS 38.133, and the TCI state is selected according to one of the latest reported SSB indexes.

[0065] It is found through research that in some activation scenarios, due to the limited size of the time window (such as the aforementioned first detection window) for known cell judgment, the secondary cell that has completed cell measurement and is to be activated cannot meet the judgment conditions of the aforementioned known cell provided by the related technology and is determined as an unknown cell, affecting the activation efficiency of the secondary cell. To this end, the present application provides a secondary cell activation scheme, which realizes the effective judgment of whether the known cell can be applied to the cell activation delay of the secondary cell activation by taking the effective measurement result as the judgment condition of the known cell, avoids the problem that the secondary cell that may be a known cell in the related technology is determined as an unknown cell, and ensures the activation efficiency of the secondary cell.

[0066] Based on this, the technical solutions provided by the embodiments of the present application are described in detail below in combination with the drawings and some embodiments and application scenarios.

[0067] As shown in FIG. 2, a flowchart of an activation method 200 of a secondary cell provided by an exemplary embodiment of the present application is shown, which can be executed by a terminal, but is not limited thereto, and can be executed by hardware and / or software installed in the terminal. In this embodiment, the method 200 can include at least the following steps.

[0068] In S210, the terminal sends a valid measurement result to a network side device.

[0069] The valid measurement result can include one or more of idle state or inactive state measurement results, such as early measurement results, cell reselection measurement results, etc. The early measurement result can be understood as a measurement result obtained by the terminal before entering the connected state (such as idle or inactive).

[0070] The valid measurement result can be understood as a measurement result that meets the idle / inactive state measurement accuracy requirement and is located in a predetermined window. For example, in this embodiment, the predetermined window can be X seconds before the sending time of message 1, which can also be referred to as a validity verification window.

[0071] Optionally, the X can be achieved by protocol agreement or network side configuration, for example, in this embodiment, the value of X can be, but is not limited to, 5s, 10s, 20s, 50s, 100s. The message 1 mentioned in the context of the present application is a random access for the terminal.

[0072] The predetermined window can also be a third detection window indicated by a first timer introduced in the present application. The first timer is a timer agreed by the protocol or configured by the network side and used to determine the valid measurement result required for the activation of the secondary cell, i.e., the termination point of the third detection window indicated by the first timer is the time point for judging the validity condition.

[0073] Optionally, the termination time of the first timer (i.e., the termination point of the third detection window) is located before the sending time of the valid measurement result or message 1, i.e., the starting time of the first timer can be determined according to the timing length of the first timer and the sending time of the valid measurement result or message 1.

[0074] Optionally, the length of the third detection window can be, but is not limited to, 3s, 5s, 10s, 30s, 50s, 100s, 150s, etc., which is not limited herein.

[0075] The idle / inactive state measurement accuracy requirement mentioned in the context of the present application can be understood, but is not limited to, that for a certain to-be-measured cell, the absolute value of the difference between the measured RSRP, reference signal quality (RSRQ) and other measurement quantities and the actual true value thereof needs to be within the specified accuracy. In the embodiment, the value of the idle / inactive state measurement accuracy requirement can be agreed by a protocol or configured by a network side, which is not limited herein.

[0076] S220, the terminal determines whether the to-be-activated secondary cell can apply the cell activation delay of the known cell (performs cell activation according to the effective measurement result.

[0077] The cell activation delay can also be referred to as a cell activation delay requirement) refers to a predetermined value that needs to be met by the cell activation delay when performing cell activation. Generally, the cell activation delay of the known cell is less than the activation delay of the unknown cell.

[0078] It is worth noting that, compared with the judgment condition of the known cell provided in the related art, the effective measurement result is used as the judgment condition for whether the to-be-activated secondary cell can apply the cell activation delay of the known cell to perform cell activation in the embodiment, which realizes effective judgment of whether the secondary cell activation delay can apply the cell activation delay of the known cell and ensures the activation efficiency of the secondary cell.

[0079] Especially, when it is determined according to the effective measurement result that the to-be-activated secondary cell can apply the cell activation delay of the known cell to perform cell activation, the activation delay of the secondary cell during activation can also be reduced, and the communication performance is ensured.

[0080] In some embodiments, the effective measurement result can include, but is not limited to, at least one of the following 11)-14).

[0081] 11) The first time is used to indicate the measurement time of the effective measurement result.

[0082] Optionally, in the case where the effective measurement result corresponds to at least one measurement carrier (which can also be referred to as a measurement frequency point or a frequency point, etc.), the first time can include, but is not limited to, at least one of the following a)-b).

[0083] a) The measurement completion time corresponding to each measurement carrier. That is, the first time is determined in the granularity of the measurement carrier.

[0084] b) The measurement completion time corresponding to the measurement cell under each measurement carrier. That is, the first time is determined in the granularity of the measurement cell under the measurement carrier.

[0085] In this embodiment, by reporting the first time, the network side device can clearly know the measurement time of each measurement carrier or measurement cell in the effective measurement result, so as to consider the measurement time of the measurement result when deciding to activate the secondary cell. For example, the network side device can preferentially select the secondary cell corresponding to the effective measurement result with the latest measurement time to activate the secondary cell, and the like.

[0086] 12) sorting information, used to indicate that the effective measurement result is a measurement result sorted in a predetermined manner.

[0087] In the case where the effective measurement result corresponds to at least one measurement carrier, the predetermined manner includes at least one of the following manners 1-3.

[0088] Manner 1, according to the measurement completion time corresponding to each measurement carrier, the effective measurement result is sorted (such as sorted in ascending order or descending order of measurement completion time).

[0089] For example, it is assumed that when reporting the effective measurement result, a carrier list will be reported, and each carrier in the carrier list will have a corresponding effective measurement result, such as carrier1, carrier2, carrier3 and their respective effective measurement results. Among them, after sorting according to the measurement completion time, carrier2 is the last measurement carrier to complete the measurement (i.e. the carrier closest to the activation time), followed by carrier3 and carrier1. Therefore, when the terminal reports the effective measurement result, the sorting information corresponding to the effective measurement result is carrier2, carrier3, carrier1, that is, the effective measurement result is reported in the order of carrier2, carrier3, carrier1.

[0090] Manner 2, for each measurement cell under each measurement carrier, according to the measurement completion time corresponding to each measurement cell, the effective measurement result is sorted (such as sorted in ascending order or descending order of measurement completion time).

[0091] For example, assuming that a carrier list is reported when reporting the valid measurement result, there is a corresponding cell list under each measurement carrier in the carrier list, such as cell 1, cell 2, and cell 3 corresponding to carrier 1, the terminal can sort the valid measurement result according to the measurement completion time corresponding to each measurement cell, cell 1 is the last measurement cell to complete measurement (i.e., the cell closest to the activation time), followed by cell 3 and cell 2, and when the terminal reports the valid measurement result, the sorting information corresponding to the valid measurement result under carrier 1 is cell 1, cell 3, and cell 2, that is, the valid measurement result under carrier 1 is reported in the order of cell 1, cell 3, and cell 2.

[0092] Option 3: first sort the valid measurement result according to the measurement completion time corresponding to each measurement carrier (as shown in option 1), and then sort the valid measurement result according to the measurement completion time corresponding to each measurement cell under each measurement carrier (as shown in option 2).

[0093] For the foregoing options 1-3, the terminal can sort the valid measurement result (such as early measurement result, cell reselection measurement result, etc.) uniformly when sorting, or sort each different type of measurement result (such as early measurement result, cell reselection measurement result, etc.), which is not limited herein.

[0094] Optionally, in addition to the sorting information, the valid measurement result carries an indication information to indicate that the valid measurement result is based on the sorted measurement result, or respectively indicates that the reported measurement result is based on the sorted early measurement result and cell reselection measurement result, etc., which is not limited herein.

[0095] In addition, the terminal and the network side device have a consistent understanding of which one of the foregoing options 1-3 is used by the terminal.

[0096] In this embodiment, through the reporting of the sorting information, the network side device can clearly know which secondary cell has a measurement time closer to the sending time of the secondary cell activation command according to the sorting information of the valid measurement result, so as to comprehensively consider the sorting information when deciding to activate the secondary cell. For example, the network side device can preferentially select the secondary cell corresponding to the valid measurement result with the closest measurement time to the secondary cell activation time for activation.

[0097] 13) a fourth indication information, used for indicating a measurement result in the valid measurement results that can satisfy the known cell judgment rule, or used for indicating from which measurement result in the valid measurement results the known cell judgment rule can be satisfied, for the network side device to refer to the measurement result indicated by the fourth indication information that can satisfy the known cell judgment rule to make a decision on the secondary cell activation. For example, the network side device can preferentially select the secondary cell corresponding to the measurement result that can satisfy the known cell judgment rule and has the shortest time distance from the measurement time to the secondary cell activation time to activate.

[0098] Optionally, the measurement result in the valid measurement results that can satisfy the known cell judgment rule indicated by the fourth indication information is determined according to at least one of the second time and the third time. The second time can be achieved by protocol convention or network side configuration, etc., to indicate that the valid measurement result of the terminal in the second time can satisfy the known cell judgment rule. For example, when the terminal acquires the valid measurement result, if the valid measurement result is acquired based on the second time, it can be determined that the secondary cell corresponding to the valid measurement result can satisfy the known cell judgment rule and is reported to the network side device.

[0099] Optionally, the end point of the second time can be, but is not limited to, the start point of the validity detection window or the sending time of the message 1.

[0100] Similar to the second time, the third time can also be achieved by protocol convention or network side configuration, etc., to indicate that the measurement result of the terminal when completing the measurement after the third time can satisfy the known cell judgment rule. For example, when the terminal acquires the valid measurement result, if the acquisition time of the valid measurement result is after the third time, it can be determined that the secondary cell corresponding to the valid measurement result can satisfy the known cell judgment rule and is reported to the network side device.

[0101] Exemplarily, for the carrying manner of the fourth indication information, assuming that the ordering information in the valid measurement result reported by the terminal is SCell1, SCell2, SCell4, SCell3 (inverted order of measurement completion time, i.e., SCell1 completes measurement last, but is closest to the activation time, so it is ranked first), based on the second time or the third time, it is determined that the valid measurement result corresponding to the SCell that completes measurement after SCell4 may satisfy the known cell determination rule, then the fourth indication information can be carried in the measurement result of SCell4, i.e., the network side device can know that only SCell1, SCell2 and SCell4 may satisfy the known cell determination rule. Thus, the network side device can preferentially select the SCell with good measurement result and closest to the secondary cell activation time from the SCell satisfying the known cell determination rule for activation.

[0102] It should be noted that the aforementioned known cell determination rule can reuse the determination condition of the known cell in the related art, or can be the known cell determination rule provided by the embodiment of the application for known cell determination, i.e., the first determination rule, the second determination rule, the third determination rule, the fourth determination rule, the fifth determination rule, the sixth determination rule, the seventh determination rule, etc. mentioned below, which is not limited here. To avoid repetition, the related description of the first determination rule, the second determination rule, the third determination rule, the fourth determination rule, the fifth determination rule, the sixth determination rule, and the seventh determination rule can refer to the related description below.

[0103] 14) The fifth indication information is used to indicate a specific object satisfying the sixth determination rule, so that the network side device can refer to the measurement result indicated by the fourth indication information to make a decision on the secondary cell activation. Wherein, the sixth determination rule is a determination rule for the terminal to determine whether the secondary cell to be activated is a known cell, and the related description can refer to the description below, which will not be repeated here.

[0104] The specific object includes at least one of the measurement carrier, the valid measurement result corresponding to the measurement carrier, the measurement cell, the valid measurement result corresponding to the measurement cell, and the measurement result corresponding to the first timer corresponding to the measurement carrier or the measurement cell.

[0105] Based on this, the content indicated by the fifth indication information includes but is not limited to at least one of the following a)-e).

[0106] a) a measurement carrier satisfying the sixth judgment rule. The "measurement carrier satisfying the sixth judgment rule" can be understood as: the effective measurement result corresponding to the measurement carrier satisfies the sixth judgment rule, i.e., based on the effective measurement result corresponding to the measurement carrier, it is determined that the secondary cell to be activated is a known cell, and then the terminal can report the measurement carrier to the network side device.

[0107] b) the effective measurement result corresponding to the measurement carrier satisfying the sixth judgment rule.

[0108] c) a measurement cell satisfying the sixth judgment rule. The "measurement cell satisfying the sixth judgment rule" can be understood as: the effective measurement result corresponding to the measurement cell satisfies the sixth judgment rule, i.e., based on the effective measurement result corresponding to the measurement cell, it is determined that the secondary cell to be activated is a known cell, and then the terminal can report the measurement cell to the network side device.

[0109] d) the effective measurement result corresponding to the measurement cell satisfying the sixth judgment rule.

[0110] e) the measurement result corresponding to the first timer satisfying the sixth judgment rule. The first timer is a measurement result required for determining the activation of the secondary cell, which is agreed by a protocol or configured by the network side. In this embodiment, the "first timer corresponding to the measurement carrier or measurement cell" can be understood as: the first timer is configured in the granularity of the measurement carrier or measurement cell, such as the effective measurement result in the first timer corresponding to the measurement carrier satisfying the sixth judgment rule.

[0111] As an optional implementation manner, the fifth indication information can be indicated by 1 bit (bit) information, or for the case that the specific object is the measurement result corresponding to the first timer and the terminal and the network side device have consistent understanding of the first timer, the fifth indication information can also be the timing length of the first timer, i.e., the timing length of the first timer indicates that the measurement result corresponding to the first timer satisfies the sixth judgment rule.

[0112] In some embodiments, for the valid measurement result, if the timing length of the first timer is less than the length of the first detection window, the valid measurement result can be the measurement result within the first detection window; or, when the timing length of the first timer is not less than the length of the first detection window, the valid measurement result includes the measurement result within the first detection window and other measurement results satisfying the idle / inactive state measurement accuracy requirement determined based on the first timer. Thus, by introducing the first timer and reporting the valid measurement result based on the first timer, the network side device can be assisted to determine whether the to-be-activated secondary cell is a known cell, so as to ensure the activation efficiency of the secondary cell. The first detection window is used to determine whether the secondary cell is a known cell.

[0113] It is worth noting that the length of the first detection window mentioned in the context of the present application can be preconfigured by the network side or agreed by the protocol, and the value is related to factors such as activation scenario, FR1 frequency point, FR2 frequency point, power class, etc., as shown in Table 1. In Table 1, "measCycleSCell" can be understood as a secondary cell measurement cycle, and "DRX cycles" can be understood as a discontinuous reception cycle. The second activation command is the one with the latest reception time in the semi-persistent CSI-RS corresponding to the PDCCH TCI, PDSCH TCI and valid CQI report.

[0114] In some embodiments, the determination occasion for determining whether the to-be-activated secondary cell can apply the cell activation delay of the known cell in the foregoing S220 can include but is not limited to: after the terminal receives the activation command of the secondary cell, or after the terminal obtains the valid measurement result, but before receiving the activation command of the secondary cell, without limitation.

[0115] In addition, there can be various implementation manners for the process of determining whether the to-be-activated secondary cell can apply the cell activation delay of the known cell for cell activation by the terminal according to the valid measurement result in the foregoing S220. For example, as shown in FIG. 3, the process of determining whether the to-be-activated secondary cell can apply the cell activation delay of the known cell for cell activation by the terminal according to the valid measurement result in the foregoing S220 can include but is not limited to the following S221-S222.

[0116] Table 1

[0117] S221, the terminal determines whether the to-be-activated secondary cell is a known cell according to the valid measurement result.

[0118] S222, in a case where it is determined that the to-be-activated secondary cell is a known cell, determining that the to-be-activated secondary cell can apply a cell activation delay of a known cell for activation of the secondary cell. Thus, compared with the cell activation delay in a case where the secondary cell is an unknown cell, the embodiment applies the cell activation delay of the known cell for activation of the secondary cell determined as the known cell, can reduce the cell activation delay, realize fast activation of the secondary cell, and ensure communication performance.

[0119] In addition, for a case where the to-be-activated secondary cell is determined to be not a known cell, the terminal can determine that the to-be-activated secondary cell cannot apply a cell activation delay of a known cell for activation of the secondary cell, or the terminal activates the secondary cell based on an activation procedure of an unknown cell.

[0120] In some embodiments, as shown in FIG. 4, the process in which the terminal determines whether the to-be-activated secondary cell is a known cell according to the effective measurement result in the foregoing S221 can include S2211-S2212.

[0121] S2211, the terminal determines a known cell determination rule according to first information.

[0122] S2212, in a case where the terminal determines that the effective measurement result satisfies the known cell determination rule, the terminal determines that the secondary cell is the known cell.

[0123] It is worth noting that the terminal and the network side device understand the known cell determination rule determined by the terminal consistently, thereby ensuring that the terminal and the network side device consistently understand whether the to-be-activated secondary cell is a known cell, to ensure fast activation of the secondary cell.

[0124] The first information can include but is not limited to at least one of 21)-25).

[0125] 21) whether the effective measurement result includes a first time, the first time being used to indicate a measurement time of the effective measurement result. Details about the first time are not described herein.

[0126] 22) a frequency band deployment mode corresponding to the effective measurement result. The frequency band deployment mode can include but is not limited to one of FR1, FR2, etc.

[0127] Based on this, the frequency band deployment mode corresponding to the effective measurement result can be understood as that the effective measurement result is measured based on a measurement carrier or a measurement cell under a deployment mode of FR1 or FR2, etc.

[0128] 23) whether a first timer is configured, the first timer being used to determine valid measurement results required at the time of the secondary cell activation, such as measurement results within a third detection window (i.e. running time of the first timer) indicated by the first timer can be determined as valid measurement results required at the time of the secondary cell activation.

[0129] 24) whether a known cell exists in a measurement cell corresponding to the valid measurement results.

[0130] 25) whether a first condition is met; wherein the first condition comprises at least one of the following condition 1-condition 2.

[0131] Condition 1: length of a second detection window is less than a first threshold; wherein the second detection window is used for the determination of the known cell.

[0132] Optionally, the second detection window can comprise but is not limited to at least one of the following a)-e).

[0133] a) a first window for cell measurement when the terminal is in an idle state or an inactive state.

[0134] Optionally, the first window can be implemented by a protocol agreement or a network side configuration. For example, for the case of the network side configuration, the first window can be configured by reusing but not limited to the parameter "measIdleValidityDuration-r18" in the related art.

[0135] b) a second window for at least one of early measurement, cell reselection measurement performed by the terminal.

[0136] Optionally, the second window can be implemented by a protocol agreement or a network side configuration. For example, for the case of the network side configuration, the second window can be configured by reusing but not limited to the parameter "measReselectionValidityDuration-r18" in the related art.

[0137] c) a larger one between the first window and the second window.

[0138] d) a smaller one between the first window and the second window.

[0139] e) a third detection window, the third detection window being a detection window indicated by the first timer, such as length of the third detection window can be the same as running length of the first timer. In the embodiment, the length of the third detection window can be but is not limited to 3s, 5s, 10s, 30s, 50s, etc., which is not limited herein.

[0140] Condition 2: the length of the first duration is less than a second threshold, wherein the first duration is a time between a sending time of the valid measurement result or a sending time of a message (Message 1) or a measurement time corresponding to the secondary cell and a receiving time of a first activation command for activating the secondary cell. In this embodiment, the first activation command can include, but is not limited to, a secondary cell activation command, an RRC reconfiguration message, and the like.

[0141] Optionally, for Condition 2, if the first time is carried in the valid measurement result, the first duration can be a time between a sending time of the valid measurement result or a measurement time corresponding to the secondary cell and a receiving time of a first activation command.

[0142] If the first time is not carried in the valid measurement result, the first duration can be a time between a sending time of the Message 1 and a receiving time of a first activation command.

[0143] In addition, the acquisition manner of the foregoing first threshold and second threshold can be agreed by a protocol or configured by a network side, which is not limited herein.

[0144] Based on the foregoing different first information, assuming that the valid measurement result includes a measurement result of the secondary cell, the implementation process of the terminal determining the known cell judgment rule according to the first information in S2211 is introduced below in combination with implementation modes 1-7, and the content is as follows.

[0145] Implementation mode 1: first judgment rule

[0146] The terminal can determine that, in a case where the valid measurement result includes the first time and a frequency band deployment manner corresponding to the valid measurement result is FR1, the known cell judgment rule includes a first judgment rule, and then determines whether the secondary cell is a known cell according to the first judgment rule.

[0147] The first judgment rule includes at least one of rules 11-13.

[0148] Rule 11: the sending time of the valid measurement result is located in a first detection window, and the first detection window is located before the receiving time of the first activation command, that is, if the terminal sends the valid measurement result in the first detection window before receiving the first activation command, it can be determined that the secondary cell to be activated is a known cell.

[0149] Optionally, for the rule 11, the first judging rule can further include: a Synchronization Signal and PBCH block (SSB) measured in the first detection window keeps a detectable state. The SSB keeps a detectable state in the embodiment can be understood as that the SSB keeps a detectable state at all times, or the SSB keeps a detectable state when the terminal expects or needs to detect the SSB. The SSB corresponds to the secondary cell to be activated.

[0150] Optionally, the SSB keeping a detectable state in the rule 11b can be determined according to the cell identification condition specified in sections 9.2 and 9.3 of TS38.133.

[0151] Rule 12: The SSB measured in the first detection window keeps a detectable state during the cell activation delay.

[0152] The SSB keeps a detectable state in the rule 12 can be determined according to the cell identification condition specified in sections 9.2 and 9.3 of TS38.133.

[0153] In addition, the SSB corresponds to the secondary cell to be activated, and the valid measurement result includes a measurement result corresponding to the secondary cell.

[0154] Rule 13: The length of the second duration is not longer than the length of the first detection window, wherein the second duration is the time from the validity verification window (such as the start time of the validity verification window, a certain agreed time in the validity verification window, etc.) to the receiving time of the first activation command, the validity verification window is located before the sending time of the valid measurement result or the message 1, and is used to determine the valid measurement result.

[0155] The validity verification window is used to verify whether the measurement result when the terminal is in idle / inactive state is valid. Optionally, the length of the validity verification window can be protocol agreement or network side configuration implementation. For example, in the embodiment, the length of the validity verification window can be 5s, 10s, 20s, 50s, 100s, etc.

[0156] In the implementation 1, when the terminal performs idle / inactive state measurement and reports an effective measurement result, if the effective measurement result includes a measurement result of a secondary cell to be activated, the terminal can determine whether the secondary cell to be activated is a known cell according to a first determination rule, and if yes, determine that the cell activation delay requirement of the known cell can activate the secondary cell, thereby reducing the activation delay of the secondary cell compared with the activation mode corresponding to an unknown cell, and realizing fast activation of the secondary cell.

[0157] Implementation 2: Second determination rule

[0158] The terminal can determine that the known cell determination rule includes a second determination rule when the effective measurement result does not include the first time and the frequency band deployment mode corresponding to the effective measurement result is FR2, and further determine whether the secondary cell is a known cell according to the second determination rule.

[0159] The second determination rule can include, but is not limited to, at least one of the following rules 21-23.

[0160] Rule 21: The sending time of the effective measurement result is within a first detection window, and the first detection window is before the receiving time of a second activation command. The second activation command is the one with the latest receiving time among PDCCH TCI, PDSCH TCI and effective CQI report corresponding semi-persistent CSI-RS. In this embodiment, the second activation command and the second activation command are both used for activation of the secondary cell, but they can correspond to different activation scenarios, which are not limited here.

[0161] Optionally, for rule 21, the second determination rule can further include that the receiving time of the second activation command is later than the sending time of the effective measurement result or the message 1, and is not later than the receiving time of the MAC-CE TCI activation command.

[0162] Rule 22: The target SSB detected within a third duration remains in a detectable state during the cell activation delay, and the TCI state is determined according to the target SSB, such as determined according to one of the target SSBs. Wherein the third duration is the time between the sending time of the effective measurement result or the sending time of the message 1 and the sending time of the effective CQI report, the target SSB corresponds to the secondary cell, and the measurement result of the secondary cell is included in the effective measurement result.

[0163] In the rule 22, the "target SSB detected in the third time duration keeps a detectable state during the cell activation delay" can be determined according to the cell identification condition specified in sections 9.2 and 9.3 of TS 38.133.

[0164] Rule 23: The fourth time duration is not longer than the length of the first detection window, wherein the fourth time duration is the time between the start time of the validity verification window (or a certain time in the validity verification window, etc.) and the receiving time of the second activation command, the validity verification window is located before the sending time of the valid measurement result or message 1, and is used to determine the valid measurement result.

[0165] In some embodiments, before determining whether the secondary cell is a known cell based on the second judgment rule, the terminal can also determine whether a second condition is met, and if it is determined that the second condition is met, the terminal determines whether the second judgment rule is met according to the valid measurement result. The second condition can include, but is not limited to, at least one of the following conditions 1-2.

[0166] Condition 1: The terminal supports idle / inactive state beam measurement reporting, and the measurement carrier corresponding to the valid measurement result is configured with idle / inactive state beam measurement configuration (measconfigidle-r16).

[0167] Condition 2: The valid measurement result further includes the index of the target SSB corresponding to the secondary cell to be activated.

[0168] In the implementation mode 2, when the terminal performs idle / inactive state measurement and reports a valid measurement result, if the valid measurement result includes the measurement result of the secondary cell to be activated, the terminal can determine whether the secondary cell to be activated is a known cell according to the second judgment rule, and if so, it is determined that the cell activation delay requirement of the known cell activates the secondary cell. Thus, compared with the activation mode corresponding to the unknown cell, the activation delay of the secondary cell can be reduced, and the fast activation of the secondary cell can be realized.

[0169] Implementation mode 3: Third judgment rule

[0170] When the terminal includes the first time in the valid measurement result and the frequency band deployment mode corresponding to the valid measurement result is FR1, the terminal can determine that the known cell judgment rule includes a third judgment rule, and further determine whether the secondary cell is a known cell according to the third judgment rule.

[0171] The third determination rule can include, but is not limited to, at least one of the following rules 31-32.

[0172] Rule 31: The length of the fifth duration is not longer than the length of the first detection window. The fifth duration is the time between the first time and the time of receiving the first activation command. The first time is the measurement time of the valid measurement result corresponding to the to-be-activated secondary cell, for example, the first time can be the measurement time of the valid measurement result at the measurement frequency point corresponding to the secondary cell.

[0173] Optionally, for rule 31, the third determination rule can further include, but is not limited to: the SSB measured in the first detection window remains detectable. The "SSB remains detectable" can be understood as that the SSB always remains detectable, or the SSB is in a detectable state when the terminal expects or needs to detect the SSB.

[0174] Rule 32: The SSB measured in the first detection window remains detectable during the cell activation delay.

[0175] Optionally, the "SSB measured in the first detection window remains detectable" in the third determination rule can be determined according to the cell identification conditions specified in sections 9.2 and 9.3 of TS 38.133.

[0176] In the third implementation, when the terminal performs idle / inactive state measurement and reports a valid measurement result, if the valid measurement result includes the measurement result of the to-be-activated secondary cell, the terminal can determine whether the to-be-activated secondary cell is a known cell according to the third determination rule. If yes, it is determined that the cell activation delay of the known cell requires to activate the secondary cell, thereby compared with the activation mode corresponding to the unknown cell, the activation delay of the secondary cell can be reduced, and the fast activation of the secondary cell is realized.

[0177] Implementation 4: Fourth determination rule

[0178] The terminal can determine that the known cell determination rule includes a fourth determination rule when the first time is included in the valid measurement result and the frequency band deployment mode corresponding to the valid measurement result is FR2, and then determine whether the secondary cell is a known cell according to the fourth determination rule.

[0179] The fourth determination rule can include, but is not limited to, at least one of the following rules 41-42.

[0180] Rule 41: The sixth duration is not longer than the length of the first detection window, wherein the sixth duration is the time between the first time and the receiving time of the second activation command, the second activation command is the one with the latest receiving time among the PDCCH TCI, the PDSCH TCI and the effective CQI report corresponding semi-persistent CSI-RS.

[0181] Optionally, for rule 41, the fourth judgment rule can further include that the receiving time of the first activation command is later than the first time and no later than the receiving time of the MAC-CE TCI activation command. Wherein the first time is the measurement time of the effective measurement result corresponding to the secondary cell to be activated, for example, the first time can be the measurement time of the effective measurement result under the measurement frequency point corresponding to the secondary cell.

[0182] Rule 42: The target SSB detected in the seventh duration keeps a detectable state, and the TCI state is determined according to the target SSB, the seventh duration is the time between the first time and the sending time of the effective CQI report, and the target SSB is the SSB corresponding to the secondary cell. Wherein the first time is the measurement time of the effective measurement result corresponding to the secondary cell to be activated, for example, the first time can be the measurement time of the effective measurement result under the measurement frequency point corresponding to the secondary cell.

[0183] Optionally, the "target SSB detected in the seventh duration keeps a detectable state" in the fourth judgment rule can be determined according to the cell identification conditions specified in sections 9.2 and 9.3 of TS 38.133.

[0184] In some embodiments, before determining whether the secondary cell is a known cell based on the fourth judgment rule, the terminal can further determine whether the second condition is met, and if it is determined that the second condition is met, it is further determined whether the second judgment rule is met according to the effective measurement result. Wherein the second condition can refer to the related description in the foregoing implementation manner 2, which will not be described here.

[0185] In the present implementation manner 4, when the terminal performs idle / inactive state measurement and reports the effective measurement result, if the effective measurement result contains the measurement result of the secondary cell to be activated, the terminal can determine whether the secondary cell to be activated is a known cell according to the fourth judgment rule, and if so, it is determined that the cell activation delay requirement of the known cell can activate the secondary cell. Therefore, compared with the activation mode corresponding to the unknown cell, the activation delay of the secondary cell can be reduced, and the fast activation of the secondary cell can be realized.

[0186] Implementation manner 5: Fifth judgment rule

[0187] The terminal can determine that the known cell determination rule includes a fifth determination rule when it is determined that the first condition is met, and further determine whether the secondary cell is a known cell according to the fifth determination rule.

[0188] The fifth determination rule can include, but is not limited to, that the valid measurement result corresponding to the secondary cell meets the idle / inactive state measurement accuracy requirement and is located within a validity verification window, and the validity verification window is located before the sending time of message 1. The idle / inactive state measurement accuracy requirement can be agreed by a protocol or configured by a network side, which is not limited here.

[0189] In some embodiments, for the case where the frequency spectrum deployment mode corresponding to the valid measurement result is FR2, the terminal can further determine whether a second condition is met before determining whether the secondary cell is a known cell based on the fifth determination rule, and further determine whether the second determination rule is met according to the valid measurement result when it is determined that the second condition is met. The second condition can refer to the related description in the foregoing implementation manner 2, which is not repeated here.

[0190] In the present implementation manner 5, when the terminal performs idle / inactive state measurement and reports a valid measurement result, if the valid measurement result includes the measurement result of the secondary cell to be activated, the terminal can determine whether the secondary cell to be activated is a known cell according to the fifth determination rule, and if so, determine that the cell activation time delay requirement of the known cell can activate the secondary cell. Thus, compared with the activation mode corresponding to the unknown cell, the activation time delay of the secondary cell can be reduced.

[0191] Implementation manner 6: Sixth determination rule

[0192] The terminal can determine that the known cell determination rule includes a sixth determination rule when the first timer is configured, and further determine whether the secondary cell is a known cell according to the sixth determination rule.

[0193] The sixth determination rule can include, but is not limited to, at least one of the following rules 61-63.

[0194] Rule 61: The first time is located within a third detection window, and the third detection window is located before the sending time of message 1, the first time is the measurement time of the valid measurement result corresponding to the secondary cell to be activated, and the third detection window is the detection window indicated by the first timer.

[0195] Rule 62: the measurement result of the secondary cell included in the valid measurement result satisfies idle / inactive state measurement accuracy requirement.

[0196] Rule 63: the valid measurement result includes the measurement result of the secondary cell, and an activation command of the secondary cell is received before the second timer expires, wherein the second timer is used to define the activation time when the terminal activates the secondary cell based on the valid measurement result, and when the second timer is running, it can be determined whether the secondary cell is a known cell based on the measurement result, i.e. the valid measurement result is valid.

[0197] Optionally, the starting condition of the second timer can include: the sending time of the valid measurement result or message 1, i.e. the terminal starts the second timer after completing the valid measurement result or message 1. And / or, the stopping condition of the second timer can include: receiving the first activation command or the second timer expires.

[0198] Based on the foregoing, if the terminal receives the first activation command before the second timer expires, it can be determined that the secondary cell corresponding to the valid measurement result reported before starting the second timer is a known cell.

[0199] In some embodiments, for the case where the spectrum deployment mode corresponding to the valid measurement result is FR2, the terminal can further determine whether a second condition is satisfied before determining whether the secondary cell is a known cell based on the sixth judgment rule, and in the case where it is determined that the second condition is satisfied, it is further determined whether the second judgment rule is satisfied according to the valid measurement result. The second condition can refer to the related description in the foregoing implementation manner 2, which will not be described here.

[0200] In this implementation manner 6, when the terminal performs idle / inactive state measurement and reports a valid measurement result, if the valid measurement result includes the measurement result of the secondary cell to be activated, the terminal can determine whether the secondary cell to be activated is a known cell according to the sixth judgment rule, and if so, it is determined that the secondary cell can be activated according to the cell activation delay requirement of the known cell. Thus, compared with the activation mode corresponding to the unknown cell, the activation delay of the secondary cell can be reduced, and the fast activation of the secondary cell can be realized.

[0201] Implementation manner 7: seventh judgment rule

[0202] The terminal can determine that the known cell determination rule includes a seventh determination rule in a case where there is a known cell in the measurement cell corresponding to the effective measurement result, and further determine whether the secondary cell is a known cell according to the seventh determination rule.

[0203] The seventh determination rule can include that the to-be-activated secondary cell is on the same band as at least one of the known cells in the measurement cell corresponding to the effective measurement result. That is, if the terminal determines that the to-be-activated secondary cell is on the same band as at least one of the known cells corresponding to the effective measurement result, the terminal determines that the secondary cell is a known cell.

[0204] Optionally, the known cell in the measurement cell corresponding to the effective measurement result can be determined based on a determination condition of a known cell provided in a related technology or any one of the first determination rule, the second determination rule, the third determination rule, the fourth determination rule, the fifth determination rule, and the sixth determination rule provided in the present application, but is not limited thereto.

[0205] In some embodiments, for a case where the spectrum deployment corresponding to the effective measurement result is FR2, the terminal can further determine whether a second condition is met before determining whether the secondary cell is a known cell based on the seventh determination rule, and further determine whether the second determination rule is met according to the effective measurement result in a case where it is determined that the second condition is met. The second condition can refer to the related description in the foregoing implementation 2, which will not be repeated here.

[0206] In the present implementation 7, when the terminal performs idle / inactive state measurement and reports an effective measurement result, if the effective measurement result includes a measurement result of a to-be-activated secondary cell, the terminal can determine whether the to-be-activated secondary cell is a known cell according to a seventh determination rule, and if so, determine that the cell activation delay requirement of the known cell can activate the secondary cell. Thus, compared with an activation mode corresponding to an unknown cell, the activation delay of the secondary cell can be reduced, and fast activation of the secondary cell can be achieved.

[0207] It can be understood that, since the network side device and the terminal have consistent understanding of the known cell judgment rule, the network side device can also determine whether the to-be-activated secondary cell is a known cell based on the effective measurement result reported by the terminal and the first judgment criterion, the second judgment criterion, the third judgment criterion, the fourth judgment criterion, the fifth judgment criterion, the sixth judgment criterion or the seventh judgment rule, that is, the network side device and the terminal have consistent understanding of whether the secondary cell is a known cell, so as to ensure the fast activation when the secondary cell is a known cell. The process of determining whether the to-be-activated secondary cell is a known cell based on the effective measurement result reported by the terminal and the first judgment criterion, the second judgment criterion, the third judgment criterion, the fourth judgment criterion, the fifth judgment criterion, the sixth judgment criterion or the seventh judgment rule can refer to the implementation process of the terminal side, and will not be described here.

[0208] However, it should be noted that, although the network side device can determine whether the to-be-activated secondary cell is a known cell based on the effective measurement result, the effective measurement result is only used as auxiliary information for the network side device to refer to when deciding which secondary cell to activate.

[0209] In some embodiments, for the process of determining whether the to-be-activated secondary cell can apply the cell activation delay of the known cell for cell activation according to the effective measurement result in S220, the process can further include: receiving a first activation command or a second activation command by the terminal; and determining whether the to-be-activated secondary cell can apply the cell activation delay of the known cell for cell activation according to the effective measurement result.

In this way, the effective measurement result reported by the terminal can match the needs of the network side device, or the judgment rule or parameter used by the terminal when judging the known cell according to the effective measurement result can be consistent with the understanding of the network side device, so as to ensure the effectiveness of the activation result.

[0211] The second information can include but is not limited to at least one of the following 301)-31).

[0212] 301) first enabling information, used for indicating to allow (or enable) the terminal to report the measurement time corresponding to the valid measurement result.

[0213] According to the indication of the first enabling information, the terminal can report the measurement time corresponding to the valid measurement result to the network side device, but is not limited to, according to the self-implementation (such as whether the self-supports the reporting of the measurement time) or the request of the network side device, etc., to assist the network side device to make the decision when activating the secondary cell, such as preferentially selecting the secondary cell corresponding to the measurement result with the closest measurement time to the sending time of the activation command to activate.

[0214] Optionally, assuming that the valid measurement result includes the early measurement result and the cell reselection measurement result, the first enabling information can be one, used for simultaneously indicating to allow the terminal to report the early measurement result and the cell reselection measurement result; or the first enabling information can also be two, used for respectively indicating to allow the terminal to report the early measurement result and the cell reselection measurement result, which is not limited in the embodiment.

[0215] 302) first indication information, used for indicating or requesting the terminal to report the measurement time of the valid measurement result.

[0216] According to the indication or request of the first indication information, the terminal needs to include the measurement time (i.e. the first time) in the reported valid measurement result.

[0218] 303) second enabling information, used for indicating to allow the terminal to sort the measurement time of the valid measurement result.

[0219] According to the indication of the second enabling information, the terminal can report the sorting information of the measurement time corresponding to the valid measurement result to the network side device, but is not limited to, according to the self-implementation (such as whether the self-supports the reporting of the measurement time) or the request of the network side device, etc., to assist the network side device to make the decision when activating the secondary cell, such as preferentially selecting the secondary cell corresponding to the measurement result with the closest measurement time to the sending time of the activation command to activate.

[0220] Optionally, assuming that the valid measurement results include early measurement results and cell reselection measurement results, the second enabling information can be one, for simultaneously indicating the permission of the terminal to report the ordering information of the measurement time corresponding to the early measurement results and the cell reselection measurement results; or the second enabling information can also be two, for respectively indicating the permission of the terminal to report the ordering information of the measurement time corresponding to the early measurement results and the cell reselection measurement results, which is not limited in the embodiment.

[0221] 304) second indication information, for indicating or requesting the terminal to report the ordering information of the measurement time corresponding to the valid measurement results.

[0222] Wherein, through the indication or request of the second indication information, the terminal needs to include the ordering information of the measurement time in the reported valid measurement results.

[0223] Wherein, similar to the second enabling information, the second indication information can also be one, for simultaneously indicating or requesting the terminal to report the ordering information of the measurement time corresponding to the early measurement results and the cell reselection measurement results; or the first enabling information can also be two, for respectively indicating or requesting the terminal to report the ordering information of the measurement time corresponding to the early measurement results and the cell reselection measurement results, which is not limited in the embodiment.

[0224] 305) second time, for indicating that the valid measurement results of the terminal within the second time can meet the known cell judgment rule, for assisting the network side device to make a decision when activating the secondary cell, such as preferentially selecting the secondary cell corresponding to the measurement result which can meet the known cell judgment rule to activate. Optionally, the terminal point of the second time can be but not limited to the starting point of the validity detection window or the sending time of the message 1.

[0225] 306) third time, for indicating that the measurement result of the terminal when completing the measurement after the third time can meet the known cell judgment rule, for assisting the network side device to make a decision when activating the secondary cell, such as preferentially selecting the secondary cell corresponding to the measurement result which can meet the known cell judgment rule to activate. Wherein, the third time can be understood as a time point, that is, the measurement result corresponding to the measurement completed after the time point can all meet the known cell judgment rule.

[0226] 307) first timer, for determining the valid measurement result required when activating the secondary cell. For example, the terminal point of the third detection window indicated by the first timer is the time point of judging the validity condition.

[0227] Optionally, the configuration granularity of the first timer includes at least one of the following a)-f), but is not limited to them.

[0228] a) measurement results in idle / inactive state, i.e. only one first timer is configured for any measurement results in idle / inactive state, such as early measurement results, cell reselection measurement results.

[0229] b) early measurement results, i.e. one first timer is configured for early measurement results.

[0230] c) cell reselection measurement results, i.e. one first timer is configured for cell reselection measurement results.

[0231] d) spectrum deployment, i.e. different first timers are configured for different spectrum deployment (such as FR1, FR2).

[0233] f) measurement cell, i.e. different first timers are configured for different measurement cells.

[0234] If the configuration granularity includes two or more of the aforementioned a)-f), the terminal can introduce multiple first timers for different granularities at the same time. For example, assuming that the configuration granularity includes measurement results in idle / inactive state and spectrum deployment (such as FR1, FR2), the terminal can first introduce one first timer for measurement results in idle / inactive state, and then introduce two first timers for FR1 and FR2, respectively, without limitation.

[0235] 308) a second timer, which is used to define the activation time when the terminal activates the secondary cell based on the valid measurement results.

[0236] The configuration granularity of the second timer is similar to that of the first timer, which will not be repeated here.

[0237] 309) a first parameter, which is used to configure the timing length of at least one of the first timer and the second timer.

[0238] In this embodiment, the first parameter can be realized by network side configuration or by protocol agreement. It is worth noting that for different configuration granularities of the first timer and the second timer, the first parameter can have multiple values, without limitation.

[0239] 310) third enabling information, used for indicating that the terminal is allowed to make the known cell judgment according to the sixth judgment rule.

[0240] Wherein, through the indication of the third enabling information, the terminal can, but not limited to, make the known cell judgment according to the sixth judgment rule according to its own implementation (such as whether it supports the report of measurement time) or the request of the network side device, etc.

[0241] Optionally, assuming that the valid measurement result includes the early measurement result and the cell reselection measurement result, the third enabling information can be one, used for indicating that the terminal is allowed to make the judgment on the early measurement result and the cell reselection measurement result based on the sixth judgment rule; or the second enabling information can also be two, used for indicating that the terminal is allowed to make the judgment on the early measurement result and the cell reselection measurement result based on the sixth judgment rule, which is not limited in the embodiment.

[0242] In some embodiments, in addition to the explicit indication of the third enabling information for allowing the terminal to make the known cell judgment according to the sixth judgment rule, the implicit indication can also be used, for example, if the first timer is included in the second information, it can be determined that the terminal is allowed to make the known cell judgment according to the sixth judgment rule.

[0243] 311) third indication information, used for indicating or requesting the terminal to report the valid measurement result meeting the sixth judgment rule.

[0244] Wherein, similar to the third enabling information, the second indication information can also be one, used for indicating or requesting the terminal to report the early measurement result and the cell reselection measurement result meeting the sixth judgment rule; or the first enabling information can also be two, used for indicating or requesting the terminal to report the early measurement result and the cell reselection measurement result meeting the sixth judgment rule, which is not limited in the embodiment.

[0245] As an optional implementation, the second information can be transmitted through, but not limited to, at least one of the target configuration information, the RRC connection establishment or recovery message, and the first request message. Wherein, the target configuration information is used for configuring the related parameters in the idle / inactive state measurement result report, such as the report time, the report period, etc.

[0246] Optionally, the target configuration information can be, but not limited to, transmitted in one or more of the system message, the dedicated signaling (such as the RRC signaling), etc.

[0247] The RRC connection establishment or recovery message is used to instruct the terminal to perform RRC connection establishment or recovery.

[0248] The first request message is used to instruct the network side device to request the terminal to report the effective measurement result.

[0249] Correspondingly, when the terminal sends the effective measurement result to the network side device based on the second information, the effective measurement result can be carried in the RRC connection establishment or recovery response message, a first request response message corresponding to the first request message, and the like, without limitation.

[0250] In some embodiments, the terminal can also report terminal capability information to the network side device, so that the second information sent by the network side device to the terminal matches the terminal capability of the terminal. The terminal capability information can include, but is not limited to, at least one of the following: first capability information, second capability information, and third capability information.

[0251] The first capability information is used to indicate that the terminal supports reporting the measurement time of the effective measurement result. In this way, the network side device can know the capability of the terminal in advance, i.e., support for reporting the measurement time, so that the network side device can only request the terminal to report the measurement time corresponding to the effective measurement result, preventing the network side device from requesting the measurement time from a terminal that does not support reporting the measurement time before the terminal capability is obtained, and thus avoiding the occurrence of problems such as resource waste caused by invalid indication or request behavior.

[0252] The second capability information is used to indicate that the terminal supports sorting the effective measurement result according to the measurement time. In this way, the network side device can know the capability of the terminal in advance, i.e., support for sorting the measurement result, so that the network side device can only request the terminal to report the sorting information corresponding to the effective measurement result, preventing the network side device from requesting the sorting information corresponding to the measurement result from a terminal that does not support sorting the measurement result before the terminal capability is obtained, and thus avoiding the occurrence of problems such as resource waste caused by invalid indication or request behavior.

[0253] The third capability information is used to indicate that the terminal supports known cell judgment. In this way, the network side device can know the capability of the terminal in advance, i.e., support for known cell judgment, so that the network side device can only request or instruct the terminal to perform known cell judgment, preventing the network side device from requesting or instructing a terminal that does not support known cell judgment to perform known cell judgment before the terminal capability is obtained, and thus avoiding the occurrence of problems such as resource waste caused by invalid indication or request behavior.

[0254] Through the foregoing activation scheme of the secondary cell provided in the present application, the effective measurement result can not only be used as reference information, but also be used as one of the judgment conditions of the known cell, so that the terminal can judge the reported effective measurement result according to the defined judgment rule of the known cell, and when the judgment rule of the known cell is met, the cell to be activated can be determined as the known cell. Thus, compared with the activation of the unknown cell, the terminal activates the secondary cell according to the cell activation delay of the known cell, which can effectively reduce the activation delay and ensure the communication performance.
