[0001] Cross-reference to Related Applications

[0002] The present disclosure claims priority from Chinese Patent Application No. 202411053641.3 filed on August 02, 2024 in China, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present disclosure relates to the field of communication technology, and particularly refers to a secondary cell management method, device, terminal and network equipment. BACKGROUND

[0004] Under the existing carrier aggregation (CA) architecture, the network further performs operations such as adding, activating, releasing or deactivating a secondary cell (SCell) for a terminal through radio resource control (RRC) messages by judging the quality of the SCell and the throughput requirement.

[0005] However, under the air-to-ground and ground-to-air networks such as non-terrestrial networks (NTN) or air-to-ground (ATG), the direct path and the additive white Gaussian noise (AWGN) channel model can accurately simulate the real propagation environment. At this time, in the co-located CA scenario, the coverage between the primary component carrier (PCC) of the primary cell (PCell) and the secondary component carrier (SCC) of the SCell is relatively fixed. According to the existing technology, as shown in FIG. 1, if the user terminal is within the PCC coverage and outside the SCC coverage, even if the terminal measures the SCC, the measurement result that meets the secondary cell addition condition cannot be obtained. At this time, if the terminal continues to collect the measurement result, a serious energy waste will be caused. SUMMARY

[0119] To make the technical problems to be solved by the present disclosure, technical solutions and advantages clearer, the following will be described in detail with reference to the drawings and specific embodiments.

[0120] It should be understood that the "one embodiment" or "an embodiment" mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present disclosure. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0121] In various embodiments of the present disclosure, it should be understood that the size of the serial number of the following processes does not mean the order of execution, and the execution order of the processes should be determined by its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present disclosure.

[0122] In addition, the terms "system" and "network" are often used interchangeably herein.

[0123] In the embodiments provided in the present application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that determining B according to A does not mean that B is determined only according to A, but B can also be determined according to A and / or other information.

[0124] First of all, it needs to be pointed out that in the prior art, the network equipment judges the SCC quality according to the measurement result reported by the terminal, and further assists the network to decide the addition and activation of the secondary cell and other behaviors. In the NTN / ATG network with large cell radius, if the network is deployed with co-located CA, and the application scenario of the SCC frequency is higher than the PCC, under the PCC coverage, a part of the time the terminal cannot get effective SCC measurement result, which is easy to cause the terminal energy waste. In order to save the terminal energy, the present application provides a position-based secondary cell measurement triggering method. In addition, considering that the propagation characteristics of ATG / NTN such as air-to-ground / air-to-ground network are relatively fixed, the coverage range of the carrier is relatively stable, and the coverage range and service range of the SCC are relatively fixed, the present application also provides a position-based secondary cell addition and activation method to realize the terminal energy saving.

[0125] As shown in FIG. 2, a secondary cell management method of an embodiment of the present disclosure applied to a terminal includes the following steps:

[0126] Step 101: receiving first signaling sent by a network device, wherein the first signaling carries at least one of the following information: first conditional configuration information for adding a secondary cell, second conditional configuration information for adding and activating a secondary cell, and third conditional configuration information for triggering reporting of measurement results of a measurement object, wherein the measurement results are used for secondary cell management.

[0127] Optionally, the first conditional configuration information, the second conditional configuration information, and the third conditional configuration information are used for configuring a reference position, so that the terminal performs secondary cell management according to the reference position and a self position.

[0128] In an optional implementation, the first signaling carries the first conditional configuration information or the second conditional configuration information.

[0129] In another optional implementation, the first signaling carries the first conditional configuration information and the second conditional configuration information, and the priority of the second conditional configuration information is higher than that of the first conditional configuration information.

[0130] In still another optional implementation, the first signaling carries the third conditional configuration information.

[0131] It should be noted that, in the case where the first signaling carries the first conditional configuration information, the second conditional configuration information, and the third conditional configuration information, the priority of the second conditional configuration information is higher than that of the first conditional configuration information, and the priority of the first conditional configuration information is higher than that of the third conditional configuration information. That is, if two or three of the first conditional configuration information, the second conditional configuration information, and the third conditional configuration information are satisfied at the same time, secondary cell management is performed according to the conditional configuration information with the highest priority.

[0132] Step 102: performing secondary cell management according to the position of the terminal and the first signaling.

[0133] The secondary cell management includes one of the following: adding a secondary cell, adding and activating a secondary cell, and reporting measurement results of a measurement object to the network device, wherein the measurement results are used for secondary cell management.

[0134] Optionally, as shown in FIG. 1, in the case where the terminal is in PCC coverage and out of SCC coverage, secondary cell management is performed according to the position of the terminal and the first signaling.

[0135] In the above embodiments, in a case where the first signaling carries the first condition configuration information, the terminal can determine whether to trigger adding of the secondary cell or whether to trigger adding and activating of the secondary cell according to the self position and the first condition configuration information; in a case where the first signaling carries the second condition configuration information, the terminal can determine whether to trigger adding and activating of the secondary cell according to the self position and the second condition configuration information. In this way, the terminal does not need to report the measurement and the measurement result of the secondary cell to the network device, and the adding and activating of the secondary cell can be implemented, and the problem of energy waste caused by the terminal continuously performing the secondary cell measurement in a case where the terminal is in the PCC coverage and is out of the SCC coverage can be avoided.

[0136] In a case where the first signaling carries the third condition configuration information, the terminal can determine whether to trigger the measurement and the measurement result reporting of the secondary cell according to the third condition configuration information. Since the terminal triggers the measurement of the secondary cell and reports the measurement result to the network device only in a case where it is determined according to the third condition configuration information that the secondary cell measurement and the measurement result reporting condition is met, in this way, the problem of energy waste caused by the terminal continuously performing the secondary cell measurement in a case where the terminal is in the PCC coverage and is out of the SCC coverage can be avoided.

[0137] In some optional embodiments, the first condition configuration information includes at least one of the following:

[0138] an index of the target cell;

[0139] configuration information of the target cell;

[0140] a first reference position;

[0141] a first distance threshold;

[0142] a first hysteresis factor.

[0143] Optionally, the first reference position can be a reference position determined according to a coverage area of the secondary carrier component, or can be a reference position determined according to a coverage area of the primary carrier component. For example, the first reference position is a center position of the coverage area of the secondary carrier component.

[0144] wherein the first distance threshold and the first hysteresis factor are preset values.

[0145] In some optional embodiments, the first condition configuration information further includes at least one of the following:

[0146] a first cell quality threshold;

[0147] first information used for indicating activating the target cell.

[0148] For example, the first condition configuration information comprises: an index of the target cell, configuration information of the target cell, the first reference location, the first distance threshold, the first hysteresis factor and the first cell quality threshold.

[0149] For example, the first condition configuration information comprises: an index of the target cell, configuration information of the target cell, the first reference location, the first distance threshold, the first hysteresis factor and the first information.

[0150] For example, the first condition configuration information comprises: an index of the target cell, configuration information of the target cell, the first reference location, the first distance threshold, the first hysteresis factor, the first cell quality threshold and the first information.

[0151] The first cell quality threshold can be one of a Reference Signal Received Power (RSRP) threshold, a Reference Signal Received Quality (RSRQ) threshold and a Signal to Interference plus Noise Ratio (SINR) threshold.

[0152] In some optional embodiments, in the case that the first signaling carries the first condition configuration information, the performing, according to the position of the terminal and the first signaling, the secondary cell management comprises:

[0153] determining a first distance between the position of the terminal and the first reference location;

[0154] in the case that the sum of the first distance and the first hysteresis factor is less than the first distance threshold, adding the target cell as a secondary cell of the terminal.

[0155] It should be noted that, if the distance between the position of the terminal and the first reference location is less than a threshold, it indicates that the terminal is close to the center of the target cell at this time, and based on this, it can be determined that the terminal receives a good signal quality of the target cell at this time, and the target cell can be added as a secondary cell and activated.

[0156] In the above embodiments, the terminal can determine whether the secondary cell addition condition is met based on the position of the terminal and the first reference location, the first distance threshold and the first hysteresis factor included in the first condition configuration information, and add the target cell as a secondary cell in the case that it is determined that the secondary cell addition condition is met. In this way, the terminal does not need to perform measurement on the secondary cell, nor does it need to report the measurement result to the network device, and the addition and activation of the secondary cell can be realized, thereby avoiding the problem that the terminal continuously performs measurement on the secondary cell in the case that the terminal is in the PCC coverage and out of the SCC coverage, which causes energy waste.

[0157] In some optional embodiments, in the case that the first signaling carries the first conditional configuration information, the performing, according to the position of the terminal and the first signaling, the secondary cell management comprises:

[0158] determining a first distance between the position of the terminal and the first reference position;

[0159] in the case that the first conditional configuration information further comprises the first cell quality threshold, if the sum of the first distance and the first hysteresis factor is less than the first distance threshold, and the cell quality of the target cell is greater than the first cell quality threshold, adding the target cell as a secondary cell of the terminal;

[0160] in the case that the first conditional configuration information further comprises the first information, if the sum of the first distance and the first hysteresis factor is less than the first distance threshold, adding the target cell as a secondary cell of the terminal and activating the target cell;

[0161] in the case that the first conditional configuration information further comprises the first information and the first cell quality threshold, if the sum of the first distance and the first hysteresis factor is less than the first distance threshold, and the cell quality of the target cell is greater than the first cell quality threshold, adding the target cell as a secondary cell of the terminal and activating the target cell.

[0162] Exemplarily, the first signaling is a radio resource control (RRC) signaling, and the management method of the secondary cell comprises:

[0163] Step one, the network device sends an RRC signaling, and the RRC signaling is specifically as follows:

[0164] CondSCellToAddModList auxiliary cell addition condition list

[0165] CondSCellConfig auxiliary cell addition condition

[0166] SCellIndex auxiliary cell index: 1

[0167] SCellConfigCommon auxiliary cell common configuration

[0168] SCellConfigDedicated auxiliary cell specific configuration

[0169] CondSCellAddConfig auxiliary cell addition configuration condition

[0170] Reference location: location-1

[0171] Distance threshold from reference: Threshold-1

[0172] Hysteresis: 0 m

[0173] }

[0174] }

[0175] CondSCellConfig

[0176] SCellIndex: 2

[0177] SCellConfigCommon

[0178] SCellConfigDedicated

[0179] CondSCellActiveConfig

[0180] Reference location: location-2

[0181] Distance threshold from reference: Threshold-2

[0182] RSRPThreshold: XdB

[0183] Hysteresis: 0 m

[0184] }

[0185] }

[0186] }

[0187] Wherein, the location-1 is a first reference location corresponding to a target cell with a cell index of 1, the location-2 is a first reference location corresponding to a target cell with a cell index of 2, the Threshold-1 is a first distance threshold corresponding to the target cell with the cell index of 1, the Threshold-2 is a first distance threshold corresponding to the target cell with the cell index of 2, and the XdB is a first cell quality threshold corresponding to the target cell with the cell index of 2. That is, the network configures the first condition configuration information for the two target cells through one RRC signaling.

[0188] Step two, the terminal receives the RRC signaling sent by the network device, and acquires the location-UE.

[0189] Step three, if the sum of the 2D distance between the location-UE and the location-1 and the hysteresis factor is greater than the Threshold-1, the terminal adds the target cell with the cell index of 1 (SCellIndex:1) as a secondary cell, and sends the first confirmation information that the target cell has been added as a secondary cell to the network device, and the first confirmation information includes:

[0190] a) SCellIndex:1 (cell index 1);

[0191] b) SCellAddACK:true (i.e. the second information, indicating that the target cell has been added as a secondary cell).

[0192] Step four, if the sum of the 2D distance between the location-UE and the location-2 and the hysteresis factor is greater than the Threshold-2, and the RSRP measurement result of the cell is greater than XdB, the terminal adds the target cell with the cell index of 2 (SCellIndex:2) as a secondary cell, and sends the first confirmation information that the target cell has been added as a secondary cell to the network device, and the first confirmation information includes:

[0193] a) SCellIndex:2 (cell index 2);

[0194] b) SCellActiveACK:true (i.e. the second information, indicating that the target cell has been added as a secondary cell).

[0195] In the above example, the network device configures the first conditional configuration information for the two target cells with the cell index of 1 and the cell index of 2 respectively through the RRC signaling, and the terminal determines whether to add the target cell with the cell index of 1 as a secondary cell and determines whether to add the target cell with the cell index of 2 as a secondary cell according to the first conditional configuration information.

[0196] In the above embodiments, the terminal can determine whether the secondary cell addition condition is met based on the self-position and the first reference position, the first distance threshold, the first hysteresis factor and the first cell quality threshold comprised in the first condition configuration information, and add the target cell as a secondary cell in a case where it is determined that the secondary cell addition condition is met; or the terminal can determine whether the secondary cell addition and activation condition is met according to the self-position and the first reference position, the first distance threshold, the first hysteresis factor, the first cell quality threshold and the first information comprised in the first condition configuration information, and add the target cell as a secondary cell and activate the target cell in a case where it is determined that the secondary cell addition and activation condition is met; or determine whether the secondary cell addition and activation condition is met according to the self-position and the first reference position, the first distance threshold, the first hysteresis factor and the first information comprised in the first condition configuration information, and add the target cell as a secondary cell and activate the target cell in a case where it is determined that the secondary cell addition and activation condition is met. In this way, the terminal can add and activate the secondary cell without performing secondary cell measurement and reporting the measurement result to the network device, and can avoid the problem of energy waste caused by the terminal continuously performing secondary cell measurement in a case where the terminal is in the PCC coverage and out of the SCC coverage.

[0197] In some optional embodiments, the second condition configuration information comprises at least one of:

[0198] an index of the target cell;

[0199] configuration information of the target cell;

[0200] a second reference position;

[0201] a second distance threshold;

[0211] It should be noted that, if the distance between the position of the terminal and the second reference position is less than a threshold, it indicates that the terminal is close to the center of the target cell at this time, and based on this, it can be determined that the terminal receives a good signal quality of the target cell at this time, and the target cell can be added as a secondary cell and activated.

[0212] In the above embodiments, the terminal can determine whether the secondary cell addition and activation condition is met based on the position of the terminal and the second reference position, the second distance threshold, and the second hysteresis factor included in the second conditional configuration information, and in a case where it is determined that the secondary cell addition and activation condition is met, add the target cell as a secondary cell and activate it.

[0214] determining a second distance between the position of the terminal and the second reference position;

[0215] In a case that the second condition configuration information further comprises the second cell quality threshold, if the sum of the second distance and the second hysteresis factor is less than the second distance threshold, and the cell quality of the target cell is greater than the second cell quality threshold, the target cell is added as a secondary cell of the terminal, and the target cell is activated.

[0219] the index of the target cell;

[0220] second information, wherein the second information is used to indicate that the target cell has been added as a secondary cell.

Since the terminal only triggers measurement of the secondary cell and reports the measurement result to the network device in the case where it is determined that the secondary cell measurement and measurement result reporting condition is met according to the third condition configuration information, the problem of energy waste caused by the terminal continuously performing secondary cell measurement in the case where the terminal is in the PCC coverage and the SCC coverage is avoided.

That is, if two or three of the first condition configuration information, the second condition configuration information, and the third condition configuration information are satisfied at the same time, secondary cell management is performed according to the condition configuration information with the highest priority.

[0248] In the above embodiments, the network device can realize, by sending the first signaling to the terminal, that in the case that the first signaling carries the first condition configuration information, the terminal can determine whether to trigger adding a secondary cell or whether to trigger adding and activating a secondary cell according to the self position and the first condition configuration information; in the case that the first signaling carries the second condition configuration information, the terminal can determine whether to trigger adding and activating a secondary cell according to the self position and the second condition configuration information. In this way, the terminal can realize adding and activating a secondary cell without performing secondary cell measurement and reporting measurement results, which can avoid the problem that the terminal continuously performs secondary cell measurement in the case that the terminal is in PCC coverage and out of SCC coverage, causing energy waste. In the case that the first signaling carries the third condition configuration information, the terminal can determine whether to trigger secondary cell measurement and reporting measurement results according to the self position and the third condition configuration information. Since the terminal triggers secondary cell measurement and reports measurement results to the network device only in the case that it is determined according to the third condition configuration information that the secondary cell measurement and reporting measurement results condition is met, in this way, the problem that the terminal continuously performs secondary cell measurement in the case that the terminal is in PCC coverage and out of SCC coverage, causing energy waste, can be avoided.

[0445] The network device of this embodiment can, by sending the first signaling to the terminal, enable the terminal to determine whether to trigger the addition of a secondary cell or whether to trigger the addition and activation of a secondary cell according to its own location and the first condition configuration information when the first signaling carries the first condition configuration information, to determine whether to trigger the addition and activation of a secondary cell according to its own location and the second condition configuration information when the first signaling carries the second condition configuration information, and to determine whether to trigger the measurement and measurement result reporting of a secondary cell according to its own location and the third condition configuration information when the first signaling carries the third condition configuration information. In this way, the terminal can realize the addition and activation of a secondary cell without performing secondary cell measurement and measurement result reporting, which can avoid the problem that the terminal continuously performs secondary cell measurement when the terminal is within the coverage of a PCC and outside the coverage of a SCC, resulting in energy waste. When the first signaling carries the third condition configuration information, the terminal can determine whether to trigger the measurement and measurement result reporting of a secondary cell according to its own location and the third condition configuration information. Since the terminal triggers the measurement of a secondary cell and reports the measurement result to the network device only when it determines that the condition for the measurement and measurement result reporting of a secondary cell is met according to the third condition configuration information, this can avoid the problem that the terminal continuously performs secondary cell measurement when the terminal is within the coverage of a PCC and outside the coverage of a SCC, resulting in energy waste.
