[0061] This disclosure provides a method for triggering measurement reporting, as well as a communication device, a communication system, and a storage medium.

[0062] In a first aspect, embodiments of this disclosure provide a method for triggering measurement reporting, wherein the method includes:

[0063] The terminal receives first information; the first information is used to indicate the activation or deactivation of at least one first cell.

[0064] When a second cell exists in at least one of the first cells, the measurement results of the second cell are sent to the network device;

[0065] The second cell is a cell in the first cell that meets two or more of the following conditions:

[0066] The first information indicates a second cell that has switched from a deactivated state to an activated state;

[0067] The second cell is a Class 1 cell within the first frequency range;

[0068] The measurement results for the second cell are valid.

[0069] In the above embodiments, during the process of activating or deactivating the first cell, the terminal only sends the measurement results of the second cell to the network device when it determines that there is a second cell in the first cell that simultaneously meets multiple conditions. Compared with the method of triggering measurement reporting after the terminal receives the first cell activation command, or the method of triggering measurement reporting after the terminal determines that there is a first cell with valid measurement results, this embodiment of the present disclosure does not report all cells with valid measurement results, but reports the measurement results of the second cell with valid measurement results. This can effectively reduce some unnecessary measurements, thereby reducing the number of terminal measurement reports, reducing signaling overhead, and helping the terminal save energy.

[0070] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0071] The terminal's Media Access Control (MAC) layer determines whether the second cell exists in the first cell;

[0072] If the second cell exists within the first cell, the MAC layer of the terminal sends second information to the Radio Resource Control (RRC) layer of the terminal; the second information indicates at least one of the following: the second cell exists within the first cell; the RRC layer triggers the reporting of measurement results; or an index or list of indexes of the second cell.

[0073] When a second cell exists within the first cell, sending the measurement results of the second cell to the network device includes:

[0074] When the RRC layer of the terminal receives the second information, it sends the measurement results of the second cell to the network device.

[0075] In the above embodiments, during the process of activating or deactivating the first cell by the terminal, the MAC layer of the terminal determines whether there is a second cell in the first cell that simultaneously meets multiple conditions. If there is a second cell in the first cell, the MAC layer sends second information to the RRC layer to trigger the RRC layer to send the measurement results of the second cell to the network device. This reduces the number of measurement reports during the activation process of the first cell through effective interaction between the MAC layer and the RRC layer.

[0076] In conjunction with some embodiments of the first aspect, in some embodiments, the index of the second cell is the serving cell identifier.

[0077] In the above embodiment, when the MAC layer determines that there is a second cell in the first cell, it can send second information carrying the serving cell identifier of the second cell to the RRC layer so that the RRC layer can identify the second cell and send the measurement result corresponding to the serving cell identifier to the network device.

[0078] In conjunction with some embodiments of the first aspect, in some embodiments, the Media Access Control (MAC) layer of the terminal determines whether the second cell exists in the first cell, including:

[0079] The MAC layer determines whether there is a third cell in the first cell based on the first information; the third cell is the cell in the first cell that has switched from a deactivated state to an activated state.

[0080] If the third cell exists in the first cell, the MAC layer determines whether there is a first type of cell in the third cell with a first frequency range;

[0081] If the first type of cell exists in the third cell, the MAC layer determines whether there is a cell with a valid measurement result among the first type of cells in the third cell based on the measurement results of the first cell.

[0082] In the above embodiments, during the process of activating or deactivating the first cell by the terminal, the terminal's MAC layer determines whether a third cell exists in the first cell based on the first information sent by the network device. If a third cell exists in the first cell, the MAC layer determines whether a first-class cell within a first frequency range exists in the third cell. If a first-class cell exists in the third cell, the MAC layer determines whether a cell with a valid measurement result exists within the first-class cell of the third cell based on the measurement results of the first cell. Thus, by filtering the first cell conditionally, the number of cells to be filtered is gradually reduced, improving processing efficiency and reducing the activation delay of the first cell.

[0083] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0084] The terminal's RRC layer determines whether the second cell exists in the first cell;

[0085] When a second cell exists within the first cell, sending the measurement results of the second cell to the network device includes:

[0086] When the second cell exists within the first cell, the RRC layer sends the measurement results of the second cell to the network device.

[0087] In the above embodiments, during the process of activating or deactivating the first cell by the terminal, the RRC layer of the terminal determines whether there is a second cell in the first cell, so that if it is determined that there is a second cell in the first cell, the RRC layer directly triggers the reporting of the measurement results of the second cell; thereby improving the efficiency of measurement reporting and reducing activation latency.

[0088] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0089] The terminal's MAC layer sends the first information to the RRC layer; or,

[0090] The MAC layer of the terminal sends third information to the RRC layer based on the first information, wherein the third information is used to indicate a third cell; the third cell is the cell in the first cell that has switched from a deactivated state to an activated state.

[0091] In the above embodiments, after receiving the first information, the MAC layer directly sends the first information to the RRC layer, which parses the first information and determines whether there is a second cell in the first cell that simultaneously meets multiple conditions; or, the MAC layer parses the received first information and sends the parsed fourth information to the RRC layer, which determines whether there is a second cell in the first cell that simultaneously meets multiple conditions; in this way, the measurement reporting process during the activation process of the first cell is realized through the effective interaction between the MAC layer and the RRC layer.

[0092] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0093] The MAC layer of the terminal determines whether there is a third cell in the first cell based on the first information. The third cell is the cell in the first cell that has switched from a deactivated state to an activated state.

[0094] The MAC layer of the terminal sends third information to the RRC layer of the terminal; the third information is used to indicate the third cell;

[0095] The terminal's RRC layer determines whether the second cell exists in the first cell, including:

[0096] Upon receiving the third information, the RRC layer determines whether there is a first-class cell within the first frequency range in the third cell;

[0097] If a cell of the first type exists in the third cell, the RRC layer determines whether there is a cell with a valid measurement result among the cells of the first type in the third cell.

[0098] In the above embodiment, the MAC layer determines the third cell in the first cell based on the received first information, and triggers the RRC layer to make a conditional decision in the subsequent measurement reporting process for the third cell by sending the third information to the RRC layer. Thus, the MAC layer directly determines whether a third cell exists in the first cell based on the received first information, reducing the transmission of first information between the MAC layer and the RRC layer, thereby reducing message overhead. Furthermore, the MAC layer only triggers the RRC layer to perform the subsequent measurement reporting process when it determines that a third cell exists in the first cell, which reduces unnecessary triggering of the RRC layer and is beneficial for terminal energy saving.

[0099] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0100] The MAC layer of the terminal determines whether there is a first type of cell with a first frequency range in the first cell;

[0101] If the first type of cell exists in the first cell, the MAC layer sends fourth information to the RRC layer of the terminal; wherein, the fourth information is used to indicate the first type of cell in the first cell;

[0102] The terminal's RRC layer determines whether the second cell exists in the first cell, including:

[0103] The RRC layer determines whether there is a cell in the first type of cell of the first cell that has been activated from a deactivated state; and the RRC layer determines whether there is a cell in the first type of cell of the first cell that has a valid measurement result.

[0104] In the above embodiment, the MAC layer first determines whether a first-class cell with a first frequency range exists in the first cell. If such a cell exists, the MAC layer sends fourth information to the RRC layer to trigger the RRC layer to perform conditional judgment in the subsequent measurement reporting process for the first-class cell in the first cell. This allows the RRC layer to identify a second cell that simultaneously meets multiple conditions and directly triggers the reporting of the measurement results of the second cell. Thus, the MAC layer only triggers the RRC layer to perform the subsequent measurement reporting process when a first-class cell with a first frequency range exists in the first cell, reducing unnecessary triggering of the RRC layer and promoting energy saving in the terminal.

[0105] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0106] The MAC layer of the terminal determines whether there is a third cell in the first cell based on the first information. The third cell is the cell in the first cell that has switched from a deactivated state to an activated state.

[0107] The MAC layer determines whether there is a first-class cell within the first frequency range in the third cell;

[0108] If the first type of cell exists in the third cell, the MAC layer sends fifth information to the RRC layer of the terminal; wherein, the fifth information is used to indicate the first type of cell in the third cell;

[0109] The terminal's RRC layer determines whether the second cell exists in the first cell, including:

[0110] The RRC layer determines whether there are any cells with valid measurement results among the first type of cells in the third cell.

[0111] In the above embodiment, the MAC layer determines the third cell that has been activated from the deactivated state from the first cell, and determines the first type of cell in the first frequency range in the third cell; the MAC layer informs the RRC layer of the first type of cell in the third cell through the fifth information, and the RRC layer determines whether there is a cell with valid measurement results in the first type of cell in the third cell, so that after the RRC layer determines the first type of cell with valid measurement results in the third cell, it directly sends the measurement results of the cell to the network device to complete the activation of the cell.

[0112] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0113] The MAC layer or physical layer of the terminal sends sixth information to the RRC layer, the sixth information being used by the RRC layer to determine the first type of cell within the first frequency range, and / or...

[0114] The MAC layer or physical layer of the terminal sends a seventh message to the RRC layer, which is used by the RRC layer to determine that there is a cell with a valid measurement result.

[0115] In the above embodiments, when the RRC layer determines whether there is a second cell in the first cell, the MAC layer or the physical layer sends sixth and / or seventh information to the RRC layer to assist the RRC layer in performing the corresponding conditional decision and to determine the second cell from the first cell.

[0116] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0117] The MAC layer receives the physical layer instruction from the terminal;

[0118] The physical layer indication is used to determine at least one of the following:

[0119] Does the first cell or the third cell contain a first-class cell within the first frequency range?

[0120] Does the first cell or the third cell contain cells with valid measurement results?

[0121] In the above embodiments, the MAC layer can receive physical layer instructions sent by the physical layer to determine a first type of cell in the first cell or the third cell, and / or a cell in the first cell or the third cell with valid measurement results; thereby improving the processing efficiency of the MAC layer when determining a first type of cell in the first cell or the third cell, and / or a cell in the first cell or the third cell with valid measurement results, which is beneficial to terminal energy saving.

[0122] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0123] When sending the measurement results of the second cell to the network device, the cell information of the second cell is also sent to the network device.

[0124] The cell information of the second cell includes at least one of the following:

[0125] Frequency information of the second cell;

[0126] The community sign of the second community.

[0127] In the above embodiments, while sending the measurement results of the second cell to the network device, the terminal can also send the cell information of the second cell to the network device, so that the network device can determine the second cell to which the measurement results belong based on the cell information, so that the network device can transmit data on the component carrier corresponding to the second cell, thereby improving the data transmission rate.

[0128] In conjunction with some embodiments of the first aspect, in some embodiments, the first information is carried within the control unit CE of the Media Access Control (MAC).

[0129] In the above embodiments, existing signaling can be directly reused to transmit the first information, effectively reducing signaling overhead.

[0130] In conjunction with some embodiments of the first aspect, in some embodiments, the first frequency range includes the frequency range FR2.

[0131] In the above embodiments, by limiting the first frequency range to frequency range FR2, the measurement results are reported for the activation of the first cell belonging to the first type of cell in FR2. This can effectively reduce the activation delay of the first type of cell in FR2, reduce the number of measurement reports by the terminal during the activation of the first cell, reduce signaling overhead, and help the terminal save energy.

[0183] Figure 1A This is a schematic diagram of the architecture of a communication system according to an exemplary embodiment.

[0184] like Figure 1A As shown, the communication system 100 includes a terminal 101 and a network device 102.

[0185] In some embodiments, terminal 101 includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0186] In some embodiments, network device 102 includes access network device and core network device.

[0187] In some embodiments, the access network device may be a node or device that connects a terminal to a wireless network. The access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system.

[0188] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0189] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0190] In some embodiments, a core network device may be a single device, including one or more network elements, or it may be multiple devices or a group of devices, each including one or more network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), or a Next Generation Core (NGC).

[0191] In some embodiments, the network element is, for example, the Access and Mobility Management Function (AMF).

[0192] In some embodiments, a network element is, for example, a Mobility Management Entity (MME).

[0193] In some embodiments, network elements are used for access and mobility management, such as registration management, connection management, and mobility management, and the names are not limited thereto.

[0194] In some embodiments, a network element may be a network element independent of the core network equipment.

[0195] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions provided in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in this disclosure are also applicable to similar technical problems.

[0196] The following embodiments of this disclosure can be applied to Figure 1A The communication system 100 shown, or a part thereof, but not limited to it. Figure 1A The entities shown are illustrative; a communication system may include... Figure 1A All or part of the main body, or may include Figure 1A Other entities besides the main body, the number and form of each entity are arbitrary, the connection relationship between the entities is illustrative, the entities may not be connected or may be connected, and the connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0197] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Futuregeneration radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0198] In some communication scenarios, there are Enhanced Mobile Broadband (eMBB), Ultra-Reliable Low Latency Communication (URLLC), and Massive Machine Type Communication (mMTC).

[0199] eMBB still aims to provide users with multimedia content, services, and data, and its demand is growing rapidly. On the other hand, because eMBB may be deployed in different scenarios, such as indoors, urban areas, and rural areas, its capabilities and needs vary considerably. Therefore, generalizations cannot be made, and a detailed analysis must be conducted in conjunction with the specific deployment scenario.

[0200] Typical applications of URLLC include: industrial automation, power automation, remote medical operations (surgery), and traffic safety assurance.

[0201] Typical characteristics of mMTC include: high connection density, small data volume, latency-insensitive services, low module cost, and long service life.

[0202] Carrier aggregation (CA) is a typical method in LTE and NR that trades bandwidth for data rate, in which multiple cells serve the UE. There is one and only one Primary Cell Component (PCC), which provides RRC signaling connectivity, Non-Access Stratum (NAS) functions, security, etc. The Physical Uplink Control Channel (PUCCH) exists only on the PCC. Secondary Cell Components (SCCs) only provide additional radio resources.

[0203] PCC and SCC are both referred to as the serving cell. In some embodiments, a maximum of 5 aggregated carriers are supported, meaning the maximum bandwidth after aggregation is 100MHz, and the aggregated carriers belong to the same base station. All aggregated carriers use the same Cell Radio Network Temporary Identifier (C-RNTI), and the base station implementation ensures that the C-RNTI does not conflict in the cell where each carrier is located.

[0204] In NR carrier aggregation, the aggregated cells may be cells in Frequency Range 1 (FR1) or cells in Frequency Range 2 (FR2). The definitions of FR1 and FR2 are shown in Table 1.

[0205] Table 1

[0206]

[0207] In some embodiments, to reduce FR2 SCell activation latency, a network-triggered report (of L3 measurement results) can be introduced during FR2 unknown SCell activation. For example... Figure 1B As shown, Figure 1B This is an interactive schematic diagram illustrating a triggering method for SCell measurement reporting according to an exemplary implementation embodiment. The L3 SCell measurement report is triggered by the SCell activation MAC CE. The RRC connection reconfiguration in the diagram can be a message configuring a candidate secondary cell.

[0208] The MAC CE used for SCell activation is a MAC layer command, while the measurement report is triggered by L3. The L3 layer reports all secondary cells with valid measurement results to the network device. However, some secondary cells, even if the measurement results are valid, are not the cells that the terminal wants to activate. This results in invalid reporting of measurement results, which leads to high signaling overhead.

[0209] In some embodiments, if the report type is set to reportOnActivation based on activation, and the secondary cell is activated by the MAC CE as agreed in the protocol, and meets the measurement requirements agreed in the protocol, the measurement reporting process is initiated.

[0210] In some embodiments, the measurement requirements agreed upon in the agreement include:

[0211] The measurement report entries are included in the VarMeasReportList of the measurement identifier (measId);

[0212] Set the number of reports submitted (numberOfReportsSent) for this measurement identifier (measId) in the VarMeasReportList to 0.

[0213] In some embodiments, the criteria for determining the second type of cell are as follows:

[0214] The cell has received valid measurement results from the network equipment within a certain period before receiving the handover instruction;

[0215] Cells whose SSBs are detected by the terminal within a certain period before receiving the handover instruction;

[0216] The cell whose SSB is detected by the terminal within a certain period before receiving the handover instruction and within the allowable delay time for cell handover.

[0217] The second type of cell here refers to cells that are not in the first type. That is, in some embodiments, cells that do not meet the above conditions can be considered as first type cells.

[0218] The time period before receiving the switching instruction can be a specified time such as 5 seconds before receiving the switching instruction.

[0219] In some embodiments, when a terminal receives a MAC CE for activating a SCell, it triggers measurement reporting for all secondary cells whose measurement results are valid. However, some secondary cells, even if their measurement results are valid, are not the cells the terminal wants to activate, resulting in invalid measurement reports and thus high signaling overhead. Furthermore, the MAC CE for activating a SCell is a command from the MAC layer, while the measurement report reporting is triggered by the RRC layer. During the SCell activation process, the information processing between the MAC layer and the RRC layer is unclear.

[0220] Figure 2A This is an interactive schematic diagram illustrating a measurement reporting triggering method according to an exemplary embodiment. For example... Figure 2A As shown, this disclosure relates to a measurement reporting triggering method for a communication system 100, the method comprising:

[0221] Step S2101: The network device sends the first information to the terminal.

[0222] In some embodiments, the terminal receives first information sent by the network device.

[0223] In some embodiments, the terminal may be a terminal that supports dual connectivity, multiple connectivity, or carrier aggregation.

[0224] In some embodiments, the network device may be the access network device corresponding to the serving cell or the source cell to which the terminal is currently connected.

[0225] In some embodiments, the network device may be the access network device corresponding to the primary cell or primary cell group of the terminal.

[0226] In some embodiments, the network device may be the access network device corresponding to the primary or secondary cell or the secondary cell group of the terminal.

[0227] In some embodiments, the first information is used to activate or deactivate at least one first cell.

[0228] In some embodiments, the first cell is a candidate secondary cell.

[0229] In some scenarios, the candidate secondary cell can also be a secondary cell.

[0230] In some embodiments, the first information may be a message configuring candidate secondary cells.

[0231] It is worth noting that activating the first cell can be understood as the terminal accessing the first cell activated by the first information indication, meaning that the first cell can serve as the terminal's serving cell for data transmission. Deactivating the first cell can be understood as the terminal releasing the connection with the first cell deactivated by the first information indication, so that it no longer uses the first cell for data transmission.

[0232] In some embodiments, the first information may be a first cell activation instruction.

[0233] In some embodiments, the network device may send first information to the terminal based on the downlink traffic volume to dynamically activate or deactivate one or more first cells.

[0234] Understandably, when network devices detect a surge in downlink traffic, they can send initial information to the terminal to activate one or more primary cells, increasing the terminal's data rate. Conversely, when downlink traffic is low, network devices can send initial information to the terminal to deactivate one or more primary cells, conserving the terminal's power.

[0235] In some embodiments, the terminal receives first information and activates or deactivates one or more first cells based on the first information.

[0236] It should be noted that the terminal can dynamically activate or deactivate one or more primary cells under the control of the network device to adapt to data bursts between the terminal and the network device and achieve high data throughput.

[0237] In some embodiments, the first information may include a bitmap; wherein each bit in the bitmap may map to a first cell; and different bit values ​​of each bit are used to indicate whether the first cell corresponding to that bit is activated or deactivated.

[0238] In some embodiments, the first information may be carried within the control unit CE of the Media Access Control (MAC).

[0239] Understandably, the first information can be carried in the existing signaling to reduce information overhead.

[0240] After receiving the first information, the terminal can execute a first cell activation process to activate or deactivate the first cell indicated by the first information. The first cell activation process includes a series of operations, which may cause a delay in the first cell activation. For example, the series of operations may include parsing the MAC CE to obtain the first cell activation instruction, preparing (or configuring) hardware and software (e.g., protocol stack software application, radio frequency (RF) module tuning) for reception and transmission on the first cell, automatic gain control (AGC) tuning on the first cell, and time-frequency synchronization, etc.

[0241] It is worth noting that in order to reduce the waiting time of burst downlink services sent by network devices to terminals, it is necessary to reduce the activation delay of the first cell; in some embodiments, in order to reduce the activation delay of the first cell, the reporting of measurement results can be introduced during the activation process of the first cell.

[0242] Step S2102: The terminal determines whether a second cell exists in at least one of the first cells.

[0243] In some embodiments, the terminal's Media Access Control (MAC) layer determines whether a second cell exists in at least one first cell.

[0244] In some embodiments, the second cell is a cell in the first cell that meets two or more of the following conditions:

[0245] First condition: The first information indicates that the second cell is switching from a deactivated state to an activated state;

[0246] Second condition: The second cell is a Class I cell within the first frequency range.

[0247] Third condition: The measurement results of the second cell are valid.

[0248] It is worth noting that the MAC layer of the terminal can determine whether there is a cell in the first cell that simultaneously meets the first condition, the second condition, and the third condition, i.e., the second cell.

[0249] In some embodiments, the first type of cell is not the second type of cell; the second type of cell meets the following conditions:

[0250] In the first type of cell, the cell's valid measurement results have been sent to the network device within a preset time period before the terminal receives the first information;

[0251] Within a preset time period before the terminal receives the first information, the cell's synchronization reference signal can be detected by the terminal;

[0252] Within a preset time period before the terminal receives the first information and within the handover delay time allowed for cell handover, the cell's synchronization reference signal can be detected by the terminal.

[0253] In some embodiments, the first type of cell may be an unknown cell.

[0254] In some embodiments, the first frequency range may be the frequency range corresponding to FR2.

[0255] It should be noted that in 5G mobile communication systems, the frequency band is divided into two different frequency ranges, namely FR1 and FR2. The frequency ranges corresponding to FR1 and FR2 can be found in Table 1.

[0256] In some embodiments, the measurement result may be the measurement result of layer (L)1.

[0257] In some embodiments, the measurement result may be a beam measurement result.

[0258] In some embodiments, the measurement results may include at least one of the following: L1-Reference Signal Received Power (RSRP); L1-Signal to Interference Plus Noise Ratio (SINR); Channel Quality Indicator (CQI); Precoding Matrix Indicator (PMI); Rank Indicator (RI); Channel-State-Information Reference-Signal (CSI-RS) Resource Indicator (CRI).

[0259] In some embodiments, the measurement result may be the measurement result of layer (L)3.

[0260] In some embodiments, the measurement result may be a Channel State Information (CSI) measurement result.

[0261] In some embodiments, the measurement results may include at least one of the following: L3-RSRP; SINR of the synchronization signal.

[0262] In some embodiments, a valid measurement result can be a measurement result that meets the measurement requirements.

[0263] In some embodiments, a valid measurement result is a measurement result that conforms to the measurement requirements specified in TS38.133. It is worth noting that the activation process of the first cell begins with the network device sending first information to the terminal and ends with the terminal sending measurement results to the network device. To expedite the activation process of the first cell, i.e., reduce the activation delay, after receiving the first information, the terminal can determine whether the first cell requested for activation is the second cell. If the first cell requested for activation is not the second cell, i.e., the first cell requested for activation is a known cell, since the terminal has already reported the measurement results for the known cell, to reduce unnecessary reporting of measurement results, the terminal may not send measurement results to the network device, thereby reducing air interface signaling and terminal power consumption.

[0264] In some embodiments, the MAC layer may determine whether a third cell exists in the first cell.

[0265] In some embodiments, the third cell is a cell in the first cell that has switched from a deactivated state to an activated state.

[0266] In some embodiments, the MAC layer may determine whether a third cell exists in the first cell based on the first information.

[0267] It is understandable that the first information is used to activate or deactivate one or more first cells; after receiving the first information, the MAC layer can determine the third cell that has been activated from the deactivated state based on the first information.

[0268] In some embodiments, the MAC layer determines whether a first type of cell with a first frequency range exists in the first cell.

[0269] In some embodiments, the MAC layer determines whether there is a cell in the first cell with a valid measurement result.

[0270] In some embodiments, the MAC layer determines whether there are cells in the first cell with valid measurement results based on the measurement results of the first cell.

[0271] It is worth noting that the MAC layer can identify two or more of the third cell in the first cell, the first type of cell in the first cell, and the cells in the first cell with valid measurement results, and take the intersection of the identified cells to determine whether there is a second cell in the first cell.

[0272] In some embodiments, when the MAC layer determines that a third cell exists in a first cell, the MAC layer determines whether a first-class cell with a first frequency range exists in the third cell; when the MAC layer determines that a first-class cell exists in the third cell, the MAC layer determines whether a cell with a valid measurement result exists in the first-class cell of the third cell.

[0273] In some embodiments, when the MAC layer determines that a third cell exists in a first cell, the MAC layer determines whether there is a cell with a valid measurement result in the third cell; when the MAC layer determines that a cell with a valid measurement result exists in the third cell, the MAC layer determines whether there is a first type cell in a first frequency range among the cells with valid measurement results.

[0274] It should be noted that, in the process of determining the second cell, the MAC layer may sequentially perform conditional judgments on the first cell to determine the second cell in the first cell; the execution order of the three conditions can be arbitrarily adjusted, and this embodiment of the disclosure does not limit this.

[0275] In some embodiments, the MAC layer may receive physical layer instructions from the terminal.

[0276] In some embodiments, the physical layer instructs the determination of at least one of the following:

[0277] Does the first or third cell contain a first-class cell within the first frequency range?

[0278] Are there any cells in the first or third cell that have valid measurement results?

[0279] The physical layer of the terminal can send a physical layer instruction to the MAC layer so that the MAC layer can determine the cell with valid measurement results in the first cell or the third cell, and / or the first type of cell in the first cell or the third cell, based on the physical layer instruction.

[0280] In some embodiments, the MAC layer of the terminal sends second information to the RRC layer of the terminal.

[0281] In some embodiments, if a second cell exists in the first cell, the MAC layer of the terminal sends second information to the RRC layer of the terminal.

[0282] In some embodiments, the second information indicates at least one of the following:

[0283] There is a second community within the first community;

[0284] The RRC layer triggers the reporting of measurement results;

[0285] The index or index list of the second cell.

[0286] It is understandable that, since the reporting of measurement results is triggered by the terminal's RRC layer, when the terminal's MAC layer determines that a second cell exists in the first cell, it can send second information to the RRC layer to trigger the RRC layer to perform subsequent processing.

[0287] In some embodiments, the second information may include one or more indicator bits, with different bit values ​​for indicating whether a second cell exists in the first cell.

[0288] In some embodiments, the second information may include one or more information fields, which are used to carry an index or a list of indexes for the second cell.

[0289] In some embodiments, the index of the second cell may be the serving cell identifier.

[0290] Step S2103: The terminal sends the measurement results to the network device.

[0291] In some embodiments, if a second cell exists in the first cell, the terminal sends the measurement results to the network device.

[0292] In some embodiments, if a second cell exists in the first cell, the terminal sends the measurement results of the second cell to the network device.

[0293] In some embodiments, if a second cell exists in the first cell, the terminal's Radio Resource Control (RRC) layer sends the measurement results of the second cell to the network device.

[0294] In some embodiments, when the RRC layer receives the second and / or third information sent by the MAC layer, it sends the measurement results of the second cell to the network device.

[0295] It should be noted that the reported measurement results can be used by network devices for wireless resource management, specifically, for example, for wireless resource scheduling of terminal communications. Typically, network devices only allocate the wireless resources of the serving cell to terminals for wireless communication.

[0296] In some embodiments, when sending the measurement results of the second cell to the network device, the cell information of the second cell is also sent to the network device.

[0297] In some embodiments, the cell information of the second cell includes at least one of the following:

[0298] Frequency information for the second cell;

[0299] The signage for the second residential area.

[0300] In some embodiments, the frequency information of the second cell may be the Absolute Radio Frequency Channel Number (ARFCN).

[0301] In some embodiments, the term "information" may be used interchangeably with terms such as "message," "signal," "signaling," "report," "configuration," "indication," "instruction," "command," "channel," "parameter," "field," and "data."

[0302] In some embodiments, the term "send" may be used interchangeably with terms such as "transmit," "report," or "transmit."

[0303] The measurement reporting triggering method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2103. For example, steps S2101 and S2102 may be implemented as independent embodiments, and step S2101 may be implemented as an independent embodiment, but is not limited thereto.

[0304] In some embodiments, step S2103 is optional, and one or more of these steps may be omitted or substituted in different embodiments. It is understood that if the terminal determines that there is no second cell in the first cell, it may not send the measurement results to the network device.

[0305] In some embodiments, steps S2102 and S2103 are optional, and one or more of these steps may be omitted or substituted in different embodiments. It is understood that when the network device sends a first information instruction to activate the first cell, the terminal can directly activate the first cell without determining whether a second cell exists within the first cell, and without sending measurement results to the network device.

[0306] Figure 2B This is an interactive schematic diagram illustrating a measurement reporting triggering method according to an exemplary embodiment. For example... Figure 2B As shown, this disclosure relates to a measurement reporting triggering method for a communication system 100, the method comprising:

[0307] Step S2201: The network device sends the first information to the terminal.

[0308] In some embodiments, optional implementations of step S2201 can be found in [reference needed]. Figure 2AOptional implementation methods of step S2101, and Figure 2A Other related parts in the embodiments involved will not be described in detail here.

[0309] Step S2202: The terminal determines whether a second cell exists in at least one of the first cells.

[0310] In some embodiments, the terminal's RRC layer determines whether a second cell exists in at least one first cell.

[0311] In some embodiments, the second cell is a cell in the first cell that meets two or more of the following conditions:

[0312] First condition: The first information indicates that the second cell is switching from a deactivated state to an activated state;

[0313] Second condition: The second cell is a Class I cell within the first frequency range.

[0314] Third condition: The measurement results of the second cell are valid.

[0315] It is worth noting that the RRC layer of the terminal can determine whether there is a cell in the first cell that simultaneously meets the first condition, the second condition, and the third condition, i.e., the second cell.

[0316] In some embodiments, the first type of cell is not the second type of cell; the second type of cell meets the following conditions:

[0317] Within a preset time period before the terminal receives the first information, the valid measurement results of the second type of cell have been sent to the network device;

[0318] Within a preset time period before the terminal receives the first information, the synchronization reference signal of the second type of cell can be detected by the terminal;

[0319] Within a preset time period before the terminal receives the first information and within the handover delay time allowed for cell handover, the synchronization reference signal of the second type of cell can be detected by the terminal.

[0320] In some embodiments, the first type of cell may be an unknown cell.

[0321] In some embodiments, the first frequency range may be the frequency range corresponding to FR2.

[0322] It should be noted that in 5G mobile communication systems, the frequency band is divided into two different frequency ranges, namely FR1 and FR2. The frequency ranges corresponding to FR1 and FR2 can be found in Table 1.

[0323] In some embodiments, the measurement result may be the measurement result of layer (L)1.

[0324] In some embodiments, the measurement result may be a beam measurement result.

[0325] In some embodiments, the measurement results may include at least one of the following: L1-Reference Signal Received Power (RSRP); L1-Signal to Interference Plus Noise Ratio (SINR); Channel Quality Indicator (CQI); Precoding Matrix Indicator (PMI); Rank Indicator (RI); Channel-State-Information Reference-Signal (CSI-RS) Resource Indicator (CRI).

[0326] In some embodiments, the measurement result may be the measurement result of layer (L)3.

[0327] In some embodiments, the measurement result may be a Channel State Information (CSI) measurement result.

[0328] In some embodiments, the measurement results may include at least one of the following: L3-RSRP; SINR of the synchronization signal.

[0329] In some embodiments, a valid measurement result can be a measurement result that meets the measurement requirements.

[0330] In some embodiments, a valid measurement result is a measurement result that conforms to the measurement requirements specified in TS38.133. It is worth noting that the activation process of the first cell begins with the network device sending first information to the terminal and ends with the terminal sending measurement results to the network device. To expedite the activation process of the first cell, i.e., reduce the activation delay, after receiving the first information, the terminal can determine whether the first cell requested for activation is the second cell. If the first cell requested for activation is not the second cell, i.e., the first cell requested for activation is a known cell, since the terminal has already reported the measurement results for the known cell, to reduce unnecessary reporting of measurement results, the terminal may not send measurement results to the network device, thereby reducing air interface signaling and terminal power consumption.

[0331] In some embodiments, the RRC layer can determine whether a third cell exists in the first cell.

[0332] In some embodiments, the third cell is a cell in the first cell that has switched from a deactivated state to an activated state.

[0333] In some embodiments, the MAC layer sends first information to the RRC layer.

[0334] Understandably, the first information is used to activate or deactivate the first cell. After receiving the first information, the MAC layer can send it to the RRC layer so that the RRC layer can determine whether a third cell exists in the first cell based on the first information.

[0335] It is worth noting that after receiving the first information, the MAC layer can directly send the first information to the RRC layer, which will then parse the first information to determine whether a third cell exists in the first cell.

[0336] In some embodiments, the MAC layer of the terminal sends third information to the RRC layer based on the first information.

[0337] In some embodiments, the third information is used to indicate a third cell.

[0338] It is understandable that after receiving the first information, the MAC layer can first parse the first information to determine whether there is a third cell in the first cell; and then send the third information to the RRC layer to inform the RRC layer of the third cell that has been activated from the activated state.

[0339] In some embodiments, the third information may include a bitmap, which is used to indicate a third cell.

[0340] Each bit in the bitmap can map to a first cell; different bit values ​​of each bit are used to determine whether the first cell corresponding to that bit is a third cell.

[0341] In some embodiments, the first information or the third information is used by the RRC layer to determine whether a third cell exists in the first cell.

[0342] In some embodiments, the RRC layer may determine whether a first type of cell with a first frequency range exists in the first cell.

[0343] In some embodiments, the RRC layer can determine whether there are cells in the first cell with valid measurement results.

[0344] It is worth noting that the RRC layer can identify two or more of the third cell in the first cell, the first type of cell in the first cell, and the cells in the first cell with valid measurement results, and take the intersection of the identified cells to determine whether there is a second cell in the first cell.

[0345] In some embodiments, when the RRC layer determines that a third cell exists in the first cell, the RRC layer may determine whether a first-class cell with a first frequency range exists in the third cell; when the RRC layer determines that a first-class cell exists in the third cell, the RRC layer may determine whether a cell with a valid measurement result exists in the first-class cell of the third cell.

[0346] In some embodiments, when the RRC layer determines that a third cell exists in a first cell, the RRC layer determines whether there is a cell with valid measurement results in the third cell; when the RRC layer determines that a cell with valid measurement results exists in a third cell, the RRC layer determines whether there is a first type cell in a first frequency range in the cell with valid measurement results.

[0347] It should be noted that, in the process of determining the second cell, the RRC layer can sequentially execute three conditional decisions on the first cell to determine the second cell in the first cell; the execution order of the three conditions can be arbitrarily adjusted, and this embodiment of the disclosure does not limit this.

[0348] In some embodiments, the method further includes:

[0349] The terminal's MAC layer or physical layer sends the sixth message to the RRC layer; and / or,

[0350] The terminal's MAC layer or physical layer sends the seventh message to the RRC layer.

[0351] In some embodiments, the sixth information is used by the RRC layer to determine whether a first type of cell exists within a first frequency range.

[0352] In some embodiments, the seventh information is used by the RRC layer to determine whether there are cells with valid measurement results.

[0353] In some embodiments, the sixth information is used by the RRC layer to determine whether there is a first-class cell with a first frequency range in the first cell or the third cell.

[0354] In some embodiments, the seventh information is used by the RRC layer to determine whether there is a cell with valid measurement results in the first type of cell in the first cell or the third cell.

[0355] It is worth noting that the sixth and seventh pieces of information can be auxiliary information to assist the RRC layer in making judgments. During the RRC layer's process of determining whether there exists a cell in the third cell that simultaneously satisfies the second and third conditions, the MAC layer or physical layer will send the sixth and / or seventh pieces of information to the RRC layer so that the RRC layer can determine whether the second cell exists in the first cell based on the sixth and / or seventh pieces of information.

[0356] Step S2203: The terminal sends the measurement results to the network device.

[0357] In some embodiments, if a second cell exists in the first cell, the terminal sends the measurement results to the network device.

[0358] In some embodiments, if a second cell exists in the first cell, the terminal sends the measurement results of the second cell to the network device.

[0359] In some embodiments, if a second cell exists in the first cell, the terminal's Radio Resource Control (RRC) layer sends the measurement results of the second cell to the network device.

[0360] In some embodiments, when the RRC layer determines that a second cell exists in the first cell, the RRC layer sends the measurement results of the second cell to the network device.

[0361] It should be noted that the reported measurement results can be used by network devices for wireless resource management, specifically, for example, for wireless resource scheduling of terminal communications. Typically, network devices only allocate the wireless resources of the serving cell to terminals for wireless communication.

[0362] In some embodiments, when sending the measurement results of the second cell to the network device, the cell information of the second cell is also sent to the network device.

[0363] In some embodiments, the cell information of the second cell includes at least one of the following:

[0364] Frequency information for the second cell;

[0365] The signage for the second residential area.

[0366] In some embodiments, the frequency information of the second cell may be the Absolute Radio Frequency Channel Number (ARFCN).

[0367] The measurement reporting triggering method involved in the embodiments of this disclosure may include at least one of steps S2201 to S2203. For example, steps S2201 and S2202 may be implemented as independent embodiments, and step S2201 may be implemented as an independent embodiment, but is not limited thereto.

[0368] In some embodiments, step S2203 is optional, and one or more of these steps may be omitted or substituted in different embodiments. It is understood that if the terminal determines that there is no second cell in the first cell, it may not send the measurement results to the network device.

[0369] In some embodiments, steps S2202 and S2203 are optional, and one or more of these steps may be omitted or substituted in different embodiments. It is understood that when the network device sends a first information instruction to activate the first cell, the terminal can directly activate the first cell without determining whether a second cell exists within the first cell, and without sending measurement results to the network device.

[0370] Figure 2C This is an interactive schematic diagram illustrating a measurement reporting triggering method according to an exemplary embodiment. For example... Figure 2C As shown, this disclosure relates to a measurement reporting triggering method for a communication system 100, the method comprising:

[0371] Step S2301: The network device sends the first information to the terminal.

[0372] In some embodiments, optional implementations of step S2301 can be found in [reference needed]. Figure 2A Optional implementation methods of step S2101, and Figure 2A Other related parts in the embodiments involved will not be described in detail here.

[0373] Step S2302: The terminal determines whether a second cell exists in at least one of the first cells.

[0374] In some embodiments, the MAC layer and RRC layer of the terminal jointly determine whether a second cell exists in at least one first cell.

[0375] In some embodiments, the second cell is a cell in the first cell that meets two or more of the following conditions:

[0376] First condition: The first information indicates that the second cell is switching from a deactivated state to an activated state;

[0377] Second condition: The second cell is a Class I cell within the first frequency range.

[0378] Third condition: The measurement results of the second cell are valid.

[0379] In some embodiments, the first type of cell is not the second type of cell; the second type of cell meets the following conditions:

[0380] Within a preset time period before the terminal receives the first information, the valid measurement results of the second type of cell have been sent to the network device;

[0381] Within a preset time period before the terminal receives the first information, the synchronization reference signal of the second type of cell can be detected by the terminal;

[0382] Within a preset time period before the terminal receives the first information and within the handover delay time allowed for cell handover, the synchronization reference signal of the second type of cell can be detected by the terminal.

[0383] In some embodiments, the first type of cell may be an unknown cell.

[0384] In some embodiments, the first frequency range may be the frequency range corresponding to FR2.

[0385] It should be noted that in 5G mobile communication systems, the frequency band is divided into two different frequency ranges, namely FR1 and FR2. The frequency ranges corresponding to FR1 and FR2 can be found in Table 1.

[0386] In some embodiments, the measurement result may be the measurement result of layer (L)1.

[0387] In some embodiments, the measurement result may be a beam measurement result.

[0388] In some embodiments, the measurement results may include at least one of the following: L1-Reference Signal Received Power (RSRP); L1-Signal to Interference Plus Noise Ratio (SINR); Channel Quality Indicator (CQI); Precoding Matrix Indicator (PMI); Rank Indicator (RI); Channel-State-Information Reference-Signal (CSI-RS) Resource Indicator (CRI).

[0389] In some embodiments, the measurement result may be the measurement result of layer (L)3.

[0390] In some embodiments, the measurement result may be a Channel State Information (CSI) measurement result.

[0391] In some embodiments, the measurement results may include at least one of the following: L3-RSRP; SINR of the synchronization signal.

[0392] In some embodiments, a valid measurement result can be a measurement result that meets the measurement requirements.

[0393] In some embodiments, a valid measurement result is a measurement result that conforms to the measurement requirements specified in TS38.133.

[0394] It is worth noting that the activation process of the first cell begins with the network device sending the first information to the terminal and ends with the terminal sending the measurement results to the network device. To expedite the activation process of the first cell and reduce its activation delay, after receiving the first information, the terminal can determine whether the first cell requested for activation is the second cell. If the first cell requested for activation is not the second cell, it means that the first cell requested for activation is a known cell. Since the terminal has already reported the measurement results for known cells, it can choose not to send the measurement results to the network device to reduce unnecessary reporting, thereby reducing air interface signaling and terminal power consumption.

[0395] The MAC layer and RRC layer of the terminal can jointly determine whether there is a second cell in the first cell in a variety of ways. Several optional embodiments are provided below.

[0396] Optional Implementation Example 1:

[0397] In some embodiments, the MAC layer of the terminal determines whether a third cell exists in the first cell; the RRC layer determines whether a first-class cell in the first frequency range exists in the third cell, and the RRC layer determines whether a cell with valid measurement results exists in the third cell.

[0398] It is worth noting that the MAC layer of the terminal can determine whether there is a cell in the first cell that meets the first condition, i.e., the third cell. The RRC layer of the terminal can determine whether there is a cell in the third cell that meets both the second and third conditions.

[0399] In some embodiments, the third cell is a cell in the first cell that has switched from a deactivated state to an activated state.

[0400] In some embodiments, the MAC layer of the terminal determines whether a third cell exists in the first cell based on the first information.

[0401] It is understandable that the first information is used to activate or deactivate one or more first cells; after receiving the first information, the MAC layer can determine the third cell that has been activated from the deactivated state based on the first information.

[0402] In some embodiments, the method further includes:

[0403] The MAC layer sends a third message to the RRC layer.

[0406] There is a third community within the first community;

[0407] The RRC layer triggers the reporting of measurement results;

[0408] The index or index list of the third community.

[0409] It is understandable that, since the reporting of measurement results is triggered by the terminal's RRC layer, when the terminal's MAC layer determines that a third cell exists in the first cell, it can send third information to the RRC layer to trigger the RRC layer to perform subsequent processing.

[0410] In some embodiments, when the RRC layer of the terminal receives the third information, the RRC layer can determine whether there is a first-class cell in the first frequency range in the third cell; the RRC layer determines whether there is a cell in the third cell with valid measurement results.

[0411] In some embodiments, the method further includes:

[0415] In some embodiments, the sixth information is used by the RRC layer to determine whether there is a first-class cell with a first frequency range in the third cell.

[0416] In some embodiments, the seventh information is used by the RRC layer to determine whether there is a cell with valid measurement results among the first type of cells in the third cell.

[0417] It is worth noting that the sixth and seventh pieces of information can be auxiliary information to assist the RRC layer in making judgments. During the RRC layer's process of determining whether there is a cell in the third cell that simultaneously satisfies the second and third conditions, the MAC layer or physical layer will send the sixth and / or seventh pieces of information to the RRC layer so that the RRC layer can determine whether the second cell exists in the third cell based on the sixth and / or seventh pieces of information.

[0424] In some embodiments, the MAC layer of the terminal determines whether there is a cell with a first frequency range in the first cell.

[0426] In some embodiments, the MAC layer of the terminal may first determine whether there is a third cell in the first cell; if there is a third cell in the first cell, the MAC layer determines whether there is a first type of cell in the first frequency range in the third cell.

[0427] In other embodiments, the MAC layer of the terminal may first determine whether there are first-class cells in the first cell with a first frequency range; if there are first-class cells in the first cell, the MAC layer determines whether there are cells in the first-class cells of the first cell that have been activated from a deactivated state.

[0429] In some embodiments, the physical layer indicates whether a first-class cell with a first frequency range exists in the third cell.

[0435] The third cell contains a first-class cell within the first frequency range;

[0436] The RRC layer triggers the reporting of measurement results;

[0437] Indexes or index lists of the first type of cells in the third cell.

[0438] It is understandable that when the MAC layer determines that there are first-class cells in the first frequency range in the third cell, it can send fifth information to the RRC layer to inform the RRC layer of the first-class cells in the third cell, so that the RRC layer can determine whether there are cells in the first-class cells of the third cell that meet the third condition.

[0439] In some embodiments, when the terminal's RRC layer receives the fifth information, the RRC layer determines whether there is a cell with a valid measurement result among the first type of cells in the third cell.

[0440] In some embodiments, the method further includes:

[0441] The terminal's MAC layer or physical layer sends the seventh message to the RRC layer.

[0442] In some embodiments, the seventh information is used by the RRC layer to determine whether there are cells with valid measurement results.

[0443] In some embodiments, the seventh information is used by the RRC layer to determine whether there is a cell with valid measurement results among the first type of cells in the third cell.

[0444] It is worth noting that the seventh information can be auxiliary information to assist the RRC layer in making judgments. In the process of the RRC layer determining whether there are cells in the first category of the third cell that meet the third condition, the MAC layer or physical layer will send the seventh information to the RRC layer so that the RRC layer can determine the cells in the first category of the third cell with valid measurement results based on the seventh information.

[0448] In some embodiments, the MAC layer may receive physical layer instructions from the terminal.

[0449] In some embodiments, the physical layer indicates the determination of whether a first type of cell with a first frequency range exists in the first cell.

[0456] The RRC layer triggers the reporting of measurement results;

[0465] In some embodiments, the RRC layer of the terminal may determine, based on the measurement results of the first cell, whether there are any cells with valid measurement results in the first type of cells of the first cell.

The intersection of the identified cells is then used to identify the cells that simultaneously meet the first and third conditions among the cells that meet the second condition.

[0589] This disclosure provides a method for processing information at the MAC and RRC layers during SCell activation, which effectively triggers L3 measurement reporting, avoids unnecessary measurement reporting, reduces air interface signaling, improves spectrum efficiency, and effectively saves UE energy.

[0590] Option 1: L2 makes a judgment to trigger a valid measurement report.

[0591] When the UE receives a secondary cell activation / deactivation command (SCell Activation / Deactivation MACCE) or an enhanced secondary cell activation / deactivation command (Enhanced SCell Activation / Deactivation MAC CE):

[0592] Option 1: The MAC layer determines the following conditions:

[0593] There exists an FR2 SCell that is activated from a deactivated state.

[0594] FR2 SCell is an unknown cell.

[0595] There are valid measurement results. Valid measurement results refer to the measurement results of the target FR2 SCell (that is, the FR2 SCell is activated from the deactivated state and is an unknown cell), or the measurement results for the frequency layer where the target FR2 SCell is located.

[0596] Option 2: The MAC layer determines the following conditions:

[0597] There exists an FR2 SCell that is activated from a deactivated state.

[0598] Based on the physical layer indication, FR2 is an unknown cell.

[0599] Based on the physical layer indication, it is known that there are valid measurement results. Valid measurement results refer to the measurement results of the target FR2SCell (that is, the FR2 SCell is activated from deactivation and is an unknown cell), or the measurement results of the frequency layer where the target FR2SCell is located.

[0600] If the above conditions are met, the MAC layer notifies the higher layer to trigger L3 measurement result reporting. Optionally, the ARFCN of the target FR frequency layer can also be indicated. L3 measurement result reporting is a measurement report in which the report type (reportType) of the measurement report is set to measurement reporting based on active measurement result reporting (reportOnActivation).

[0601] like Figure 6A As shown, Figure 6A This is a schematic diagram illustrating the information interaction between the MAC layer and the RRC layer during SCell activation according to an exemplary embodiment. Condition 1: At least one SCell is activated from a deactivated state; Condition 2: The SCell satisfying Condition 1 is an FR2 cell; Condition 3: The SCell satisfying either Condition 1 or Condition 2 is an unknown FR2 cell; Condition 4: The L3 measurement results of the FR2 SCell satisfying Condition 1 / 2 are valid after the SCell activation command.

[0602] Option 2: L2 and L3 make judgments to trigger a valid measurement report.

[0603] When the UE receives a secondary cell activation / deactivation command (SCell Activation / Deactivation MACCE) or an enhanced secondary cell activation / deactivation command (Enhanced SCell Activation / Deactivation MAC CE):

[0604] The MAC layer determines the following conditions:

[0605] There exists an FR2 SCell that has been activated from a deactivated state; or there exists an SCell that has been activated from a deactivated state; or there exists an FR2unknown SCell that has been activated from a deactivated state.

[0606] If the above conditions are met, the MAC layer notifies the higher layer that an FR2 cell has been activated from a deactivated state; or an SCell has been activated from a deactivated state; or an FR2 unknown SCell has been activated from a deactivated state; or, triggers the L3 measurement result reporting; optionally, it also indicates the ARFCN of the target FR frequency layer; and or, the list of SCells that meet condition 1.

[0607] After receiving the above instruction from the MAC layer, the RRC layer determines the following conditions:

[0608] SCell is an unknown cell in FR2, or FR2 SCell is an unknown cell.

[0609] There are valid measurement results. Valid measurement results refer to the measurement results of the target FR2 SCell (that is, the FR2 SCell is activated from deactivation and is an unknown cell), or the measurement results for the frequency layer where the target FR2 SCell is located.

[0610] If all the above conditions are met, the RRC layer triggers L3 measurement reporting. L3 measurement result reporting is a measurement report in which the report type (reportType) of the measurement report is set to measurement reporting based on the activated measurement result report (reportOnActivation).

[0611] like Figure 6B , Figure 6C and Figure 6D As shown, Figure 6B This is a schematic diagram of information interaction between the MAC layer and the RRC layer during SCell activation, according to an exemplary embodiment.

Figure 6D This is a schematic diagram illustrating the information interaction between the MAC layer and the RRC layer during SCell activation, according to an exemplary embodiment. Figure 4 Among them, condition 1: at least one SCell is activated from the deactivated state; condition 2: the SCell that satisfies condition 1 is an FR2 cell; condition 3: the SCell that satisfies condition 1 or condition 2 is an unknown FR2 cell; condition 4: the L3 measurement results of the FR2 SCell that satisfies conditions 1 / 2 are valid after the SCell activation command.

[0612] Option 3: L3 performs a judgment to trigger a valid measurement report when the UE receives a secondary cell activation / deactivation command (SCell Activation / Deactivation MAC CE) or an enhanced secondary cell activation / deactivation command (Enhanced SCell Activation / Deactivation MAC CE):

[0613] The MAC layer reports the MAC CE to the RRC layer, or the MAC layer notifies the RRC layer of the activated or deactivated bits of the SCell.

[0614] After receiving the above instruction from the MAC layer, the RRC layer determines the following conditions:

[0615] There exists an FR2 SCell that is activated from a deactivated state;

[0616] FR2 SCell is an unknown cell.

[0617] There are valid measurement results. Valid measurement results refer to the measurement results of the target FR2 SCell (that is, the FR2 SCell is activated from deactivation and is an unknown cell), or the measurement results for the frequency layer where the target FR2 SCell is located.

[0618] If all the above conditions are met, the RRC layer triggers L3 measurement reporting. L3 measurement result reporting is a measurement report in which the report type (reportType) of the measurement report is set to measurement reporting based on the activated measurement result report (reportOnActivation).

[0619] like Figure 6E As shown, Figure 6E This is a schematic diagram illustrating the information interaction between the MAC layer and the RRC layer during SCell activation, according to an exemplary embodiment. Figure 5 .

[0620] Among them, condition 1: at least one SCell is activated from the deactivated state; condition 2: the SCell that satisfies condition 1 is an FR2 cell; condition 3: the SCell that satisfies condition 1 or condition 2 is an unknown FR2 cell; condition 4: the L3 measurement results of the FR2 SCell that satisfies condition 1 or condition 2 are valid after the SCell activation command.
