Transmission method, device, terminal and network side equipment

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese Patent Application No. 202410165724.5 filed on February 5, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application belongs to the field of communication technology, and specifically relates to a transmission method, apparatus, terminal and network-side equipment. Background Art

[0004] Network energy conservation is of great significance for environmental sustainability and reducing operating costs. Currently, to achieve network energy conservation, energy-saving cells can be controlled to be in an energy-saving state. An energy-saving cell is a cell that supports network energy conservation, for example, a cell that supports on-demand transmission of system information. When a terminal requires the services of the energy-saving cell, an uplink request signal (e.g., a wake-up signal) can be sent to wake the energy-saving cell from an energy-saving state to a non-energy-saving state. However, in related art, after sending an uplink request signal to the energy-saving cell to wake it up, the terminal typically resides directly in the energy-saving cell for transmission. This transmission method is less flexible and can easily affect network energy conservation. Summary of the Invention

[0055] It should be noted that the terminal in the embodiment of the present application may also be referred to as user equipment (UE).

[0056] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0057] 1. Scenario where an uplink request signal (e.g., a wake-up signal) needs to be sent

[0058] Scenario A: One coverage cell and multiple hotspot cells, as shown in Figure 2a.

[0059] There are multiple capacity cells near the coverage cell. Capacity cells are also called hotspot cells. Capacity cells are NES cells (energy-saving cells) that support on-demand system message transmission. When the number of connected UEs is small, or the connected UE load is light, the network side can shut down some capacity cells to save energy. However, the coverage cell does not know how many idle UEs are currently in the cell.

[0060] Furthermore, when all capacity cells are dormant, if many idle UEs gather in the coverage cell for random access (RACH), this can increase RACH collisions. To reduce the probability of RACH collisions, if all capacity cells are turned on again, the network will not know how many UEs are there or where they are located, which will consume a lot of power.

[0061] Scenario B: As shown in Figure 2b, the UE moves from Coverage Cell A's coverage area toward the edge. When it is about to leave Coverage Cell A's coverage area, Coverage Cell B (NES Cell) is still in the on-demand system message state. If the NES Cell continues to sleep (sending only Synchronous Signal Blocks (SSBs)), the UE will not be able to obtain system messages from the NES Cell and will face the risk of losing coverage.

[0062] Scenario C: As shown in Figure 2c, multiple indoor small cells are in the on-demand system message state (i.e., energy-saving state) under the Coverage Cell. When a UE moves from outdoors to indoors, the uplink service rate may decrease due to the obstruction of the building, resulting in a degraded user experience.

[0063] 2. Random Access Process

[0064] In related technologies, random access procedures may include contention-based random access procedures and non-contention-based random access procedures. The above-mentioned random access procedures may include a four-step random access procedure (also called a Type-1 random access procedure) and a two-step random access procedure (also called a Type-2 random access procedure).

[0065] In the contention-based 4-step random access procedure (RACH), the UE first sends MSG1, which includes a preamble, to the network. After the network detects the preamble, it sends MSG2 / Random Access Response (RAR) message, which includes the preamble number detected by the network and the uplink radio resources allocated to the UE for sending MSG3. After receiving MSG2, the UE confirms that at least one of the preamble numbers carried in MSG2 matches the preamble number it sent, and then sends MSG3 containing contention resolution information based on the resources indicated by the RAR. After receiving MSG3, the network sends MSG4 containing contention resolution information. After receiving MSG4, the UE confirms that the resolution information is consistent with the one sent in MSG3, thus completing the 4-step random access.

[0066] The network includes uplink grant (UL grant) information in the RAR to indicate the MSG3 physical uplink shared channel (PUSCH) scheduling information, and includes RACH preamble ID (RAPID), temporary cell radio network temporary identity (TC-RNTI), time advance (TA), etc. If the network does not receive the MSG3 PUSCH, it can schedule the retransmission of the MSG3 PUSCH in the TC-RNTI scrambled physical downlink control channel (PDCCH).

[0067] For the contention-based random access process, different UEs randomly select preambles for transmission. In this way, different UEs may select the same preamble to send on the same time-frequency radio resources (for example, random access opportunity (RACH Occasion, RO) resources). This situation can be understood as a UE preamble conflict. In this case, different UEs will receive the same RAR. At this time, different UEs will transmit MSG3PUSCH according to the scheduling information in the RAR UL grant. Since the relevant technology does not support repeated transmission of MSG.3PUSCH, the network can only decode the PUSCH (including contention resolution information) sent by one UE on one MSG3 PUSCH scheduling resource. Therefore, the network will include the contention resolution information received in MSG3 in MSG4. If the contention resolution information in MSG4 received by the UE matches the contention resolution information sent by the UE in MSG3 PUSCH, the UE considers that the contention resolution is successful. If they do not match, the contention resolution is considered unsuccessful.

[0068] If the contention resolution is unsuccessful, the UE reselects RACH transmission resources, performs PRACH transmission, and makes the next random access attempt.

[0069] NR Rel-16 introduced the two-step random access procedure, 2-step RACH. In the first step, the UE sends MsgA to the network. After receiving MsgA, the network sends MsgB to the UE. If the UE does not receive MsgB within a certain period of time, it increments the counter counting the number of MsgA transmissions and resends MsgA. If the MsgA transmission counter reaches a certain threshold, the UE switches from the 2-step random access procedure to the 4-step random access procedure.

[0070] MsgA consists of the MsgA preamble and MsgA PUSCH. The preamble is sent on the Ro used for 2-step RACH, and the PUSCH is sent on the MsgA PUSCH resources associated with the MsgA preamble and Ro. MsgA PUSCH resources are a set of PUSCH resources configured for each PRACH slot, including time-frequency resources and DMRS resources, and are associated with the PRACH resources within the PRACH slot.

[0071] 2. Paging

[0072] 1. Paging Purpose

[0073] The purpose of paging is described in protocol 36.331 as follows:

[0074] Send a core network initiated paging message to a UE in the RRC idle (RRC_IDLE) or RRC deactivated (RRC_INACTIVE) state;

[0075] Send a paging message initiated by the access network to the UE in RRC_INACTIVE state;

[0076] Notify UEs in RRC_IDLE, RRC_INACTIVE or RRC_CONNECTED states of system message changes;

[0077] Notify UEs in RRC_IDLE, RRC_INACTIVE, or RRC_CONNECTED states of information about Earthquake and Tsunami Warning System (ETWS) primary notifications and ETWS auxiliary notifications;

[0078] Notify UEs in RRC_IDLE, RRC_INACTIVE, or RRC_CONNECTED state about Commercial Mobile Alert System (CMAS) notifications;

[0079] Notify UEs in RRC_IDLE state or UEs connected to 5GC of the modification of Extended Access Barring (EAB) parameters;

[0080] Notify the UE in RRC_IDLE or RRC_INACTIVE state to perform the E-UTRAN inter-frequency reconfiguration procedure.

[0081] The purpose of paging is described in protocol 38.331 as:

[0082] Send a paging message to a UE in RRC_IDLE or RRC_INACTIVE state.

[0083] As for the difference between the two, in fact, what distinguishes 5G from 4G is that 5G uses the Short Message field in the Downlink Control Information (DCI) format 1_0 to indicate system message changes and ETWS notifications.

[0084] 2. Paging classification

[0085] According to the source of the message, paging can be divided into:

[0086] 5GC paging, comes from 5GC, in RRC_IDLE state. When downlink data arrives for the UE in RRC_IDLE state, 5GC notifies the UE through Paging message;

[0087] RAN paging comes from the gNB. When downlink data arrives for a UE in RRC_INACTIVE state, the gNB notifies the UE to start data transmission through a RAN Paging message. The final paging message is sent by the gNB to the UE over the air interface.

[0088] 4. Cell Selection and Cell Reselection

[0089] In the cell selection and reselection process, cells can be divided into:

[0090] Acceptable cell: According to the S criterion, it can meet the minimum access requirements;

[0091] Suitable cell: According to the S criteria, it can provide normal services to the UE, and the Public Land Mobile Network (PLMN) to which the cell belongs is consistent with the UE's subscription data. The PLMN can uniquely identify a communication operator and is composed of a Mobile Country Code (MCC) and a Mobile Network Code (MNC).

[0092] Reserved cell: The cell indicated in the system information is reserved (Reserved);

[0093] Barred cell: The cell is indicated as barred in the system information.

[0094] 1. Cell selection criteria (S criteria)

[0095] During cell selection, the terminal needs to measure the channel quality of the cell being selected, even performing a channel quality assessment, to determine whether it meets the criteria for staying. This measurement criterion for cell selection is called the S criterion. If the channel quality and signal strength of a cell meet the S criterion, it may be selected as the stay cell. Meeting the S criterion requires that both Srxlev > 0 and Squal > 0. The S criterion power criterion is: received power Srxlev > 0, and the S criterion quality criterion is: received signal quality Squal > 0 during cell search.

[0096] Srxlev=Qrxlevmeas–(Qrxlevmin+Qrxlevminoffset)–Pcompensation-Qoffsettemp

[0097] Among them, Srxlev: cell selection receiving level value.

[0098] Qrxlevmeas: measured cell reception level value / signal strength, for example, Reference Signal Receiving Power (RSRP).

[0099] Qrxlevmin: Minimum receive level for a cell, configured by the network. Increasing this value for a cell makes it more difficult for it to meet the S criterion and become a suitable cell, making it more difficult for the UE to select that cell, and vice versa. This parameter should be set so that the selected cell can provide the signal quality requirements for basic services.

[0100] Qrxlevminoffset: The minimum receive level offset for a cell, configured by the network. This parameter is used only when the UE is in a VPLMN and cell selection is triggered by periodic searches for high-priority PLMNs. Increasing this value for a cell makes it more difficult for the cell to meet the S criterion and become a suitable cell, making it more difficult for the UE to select the cell, and vice versa.

[0101] Pcompensation: Used to penalize UEs that fail to reach the cell's maximum power. This value is configured by the network. When the UE's maximum allowed transmit power is less than or equal to the maximum transmit power supported by the UE's capabilities, Pcompensation = 0. When the UE's maximum allowed transmit power is greater than the maximum transmit power supported by the UE's capabilities, Pcompensation = UE's maximum allowed transmit power - UE's maximum transmit power supported by the UE's capabilities.

[0102] Qoffsettemp (network-side configuration): Temporary offset applied to this cell, configured by the network. This parameter is configured by the ConnEstFailOffset parameter in RRC and is used for connection failure control.

[0103] Squal=Qqualmeas–(Qqualmin+Qqualminoffset)-Qoffsettemp

[0104] Among them, Squal: cell selection quality value.

[0105] Qqualmeas: measured cell quality value, for example, Reference Signal Received Quality (RSRQ).

[0106] Qqualmin: Minimum received signal quality, configured by the network. This parameter indicates the minimum received signal quality required for reselection and is used to control the difficulty of cell reselection. This parameter is delivered in System Message 5. Increasing this value for a cell makes it more difficult for the cell to meet the S criterion and become a suitable cell, making it more difficult for the UE to select the cell, and vice versa.

[0107] Qqualminoffset: Minimum received signal quality offset, configured by the network. This parameter represents the minimum received signal quality offset for a cell and is applied to the cell selection criterion (S criterion) formula. This parameter is used only when the UE is in a visited PLMN (VPLMN) and cell selection is triggered by periodic searches for high-priority PLMNs. Increasing this value for a cell makes it more difficult for the cell to meet the S criterion and become a suitable cell, making it more difficult for the UE to select the cell, and vice versa.

[0108] Qoffsettemp: configured by the network side.

[0109] 2. Cell reselection criteria (R criteria)

[0110] When a UE is idle / inactive, after cell selection, it continuously monitors the signal quality of neighboring cells and the current cell in order to camp on a cell with higher priority or better channel quality. If the signal quality and rating of a neighboring cell meet the S criterion and certain reselection criteria, the UE will camp on that cell.

[0111] Measurement criteria for cell reselection:

[0112] After the UE successfully camps on the cell, it will continue to measure the cell. To minimize the UE energy consumption caused by the measurement, the RRC layer calculates the S criterion based on the RSRP / RSRQ measurement results and compares it with the intra-frequency measurement start threshold (Sintrasearch) and the inter-frequency measurement start threshold (Snonintrasearch) as the decision condition for whether to start neighbor cell measurement.

[0113] The UE measures the serving cell signal and detects the serving cell signal strength Srxlev or quality Squal.

[0114] Intra-frequency measurement start criteria: Srxlev <= Sintrasearch or Squal <= Snonintrasearch.

[0115] Inter-frequency measurement starting criteria (for frequencies of the same or lower priority): Srxlev<=Snonintrasearch or Squal<=Sintrasearch.

[0116] During the reselection process, the network can control the UE's stay by setting the priority of different frequencies. The UE will select the cell with the best channel quality at a certain frequency to provide the best service. There are three ways for the UE to obtain the frequency priority information it needs to use:

[0117] (1) System information: For a certain frequency point, the corresponding absolute priority is provided in the system information;

[0118] (2) RRC Release message: If the frequency priority is provided by dedicated RRC signaling, the priority in the System Information (SI) is ignored;

[0119] (3) Inherited from other radio access technologies (RAT).

[0120] Same-frequency and same-priority inter-frequency cell reselection criteria (R criteria):

[0121] The cell ranking criteria are defined as follows, where Rs is used for the serving cell and Rn is used for the neighboring cell:

[0122] Rs=Qmeas,s+Qhyst–Qoffsettemp;

[0123] Rn=Qmeas,n-Qoffset–Qoffsettemp;

[0124] Qmeas: RSRP measurement;

[0125] Qoffset: The offset between the target candidate cell and the current resident cell, used to adjust the difficulty of reselection and reduce the ping-pong effect. When other parameters remain constant, increasing the offset will increase the difficulty of reselecting the same-frequency or different-frequency cells with the same priority, and vice versa. For same-frequency reselection, this parameter is equal to Qoffsets,n between cells (Qoffsets,n between cells exists in the system broadcast) or 0 (Qoffsets,n between cells does not exist in the system broadcast); for different-frequency reselection, this parameter is equal to 'inter-frequency Qoffsetfrequency + inter-cell Qoffsets,n' (inter-cell Qoffsets,n exists in the system broadcast) or 'inter-frequency Qoffsetfrequency' (inter-cell Qoffsets,n does not exist in the system broadcast);

[0126] Qhyst: The hysteresis value of the serving cell measurement. This parameter is related to the slow fading characteristics of the cell environment. A larger slow fading variance indicates a larger hysteresis value. A larger hysteresis value also increases the serving cell boundary, making it more difficult to reselect to a neighboring cell. This value is used to adjust the reselection difficulty and reduce the ping-pong effect. Setting it too high can lead to delayed reselection. If the terminal initiates a connection at this time, RRC connection establishment may fail.

[0127] 5. System Information Transmission in Heterogeneous Network (Hetnet) Scenario

[0128] In the Hetnet scenario shown in Figure 2d, there are multiple capacity cells near a coverage cell. In this scenario, even if there is no traffic within the coverage cell, the coverage cell and capacity cells A+B+C still need to periodically send SSBs and system messages. When a UE residing in a coverage cell moves toward a capacity cell, it can reselect and reside in the capacity cell. This allows the UE to receive better service quality when traffic arrives, compared to transmission within the coverage cell.

[0129] At the same time, for this scenario, there are currently two types of network energy-saving methods: when the Coverage Cell determines that the data capacity demand in the cell is low, it can shut down Capacity Cell A / B / C to save network energy.

[0130] The transmission method provided in the embodiments of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0131] Please refer to FIG3 , which is a flowchart of a transmission method provided in an embodiment of the present application. The method can be executed by a terminal, as shown in FIG3 , and includes the following steps:

[0132] Step 301: The terminal sends an uplink request signal;

[0133] Step 302: The terminal selects to perform a first operation or a second operation based on the first information;

[0134] The uplink request signal is used to request system information of a first cell, where the first cell is different from a second cell, and the second cell is a serving cell or a resident cell of the terminal;

[0135] The first information includes at least one of a preset rule, target configuration information, and system information of the first cell, the preset rule is related to at least one of a cell signal quality of the first cell and a cell signal quality of the second cell, and the target configuration information is related to at least one of the first operation and the second operation;

[0136] The first operation includes performing a third operation according to the system information of the first cell, and the third operation includes at least one of the following: monitoring paging, sending a random access channel (RACH), residing in a target cell, and performing service communication in the target cell;

[0137] The second operation includes performing a fourth operation within the first time window, the fourth operation including at least one of the following: receiving system information of the first cell, monitoring Paging, sending RACH, camping on the target cell, and performing service communication in the target cell;

[0138] The target cell includes at least one of the first cells.

[0139] In this embodiment, the uplink request signal may be used to request system information of the first cell, for example, to request a system information block (SIB) of the first cell, such as SIB1 or other SIBs (such as SIB x). It should be noted that, in some scenarios, the uplink request signal may be used to request system information of the first cell, and may also be referred to as being used to request the first cell to switch from an energy-saving state to a non-energy-saving state.

[0140] In some optional embodiments, the uplink request signal may also be used to request the first cell to send a synchronization signal, send paging, monitor the RACH, adjust transmission parameters of a system message or SSB, etc. The transmission parameters may include but are not limited to at least one of a period, a quantity, and a pattern.

[0141] In some optional embodiments, the uplink request signal may also be used to indicate at least one of the following:

[0142] Temporary Mobile Subscriber Identity (TMSI);

[0143] Terminal identification (ID);

[0144] Whether the terminal has subsequent business to send;

[0145] Whether the second cell meets the conditions for the terminal to reside;

[0146] The condition / reason / event that triggers the sending of the uplink request signal.

[0147] In some optional embodiments, the uplink request signal may include but is not limited to at least one of the following: a UL wakeup signal (Wakeup Signal, WUS), a preamble sequence, MsgA, and Msg3.

[0148] The first cell may include at least one cell different from the second cell, and the second cell is the current serving cell or the resident cell of the terminal. It should be noted that the first cell and the second cell may belong to the same base station or may belong to different base stations, which is not limited in this embodiment.

[0149] The preset rule may be a rule predefined by a protocol, a rule configured by a network-side device, or a rule determined by a terminal. The preset rule is related to at least one of the cell signal quality of the first cell and the cell signal quality of the second cell, wherein the cell signal quality may be measured by at least one of a cell signal quality indicator value such as an S-criterion power standard, an S-criterion quality standard, RSRP, and RSRQ.

[0150] The target configuration information is related to at least one of the first operation and the second operation. For example, the target configuration information may include at least one of the configuration information corresponding to the first operation and the configuration information corresponding to the second operation. Alternatively, the target configuration information may include indication information for instructing the terminal to perform the first operation or the second operation. For example, if the target configuration information includes a first indication value, it indicates that the terminal is instructed to perform the first operation; if the target configuration information includes a second indication value, it indicates that the terminal is instructed to perform the second operation. It should be noted that the target configuration information is configured by the network-side device.

[0151] The system information of the above-mentioned first cell may include but is not limited to information related to at least one of the first operation and the second operation. For example, the system information of the above-mentioned first cell may include indication information for instructing the terminal to perform the first operation or the second operation, or the system information of the above-mentioned first cell may include configuration information corresponding to the second operation, etc.

[0152] The first operation may also be referred to as a first action or a first process, and the second operation may also be referred to as a second action or a second process. Monitoring Paging may also be referred to as listening to Pagin, detecting Pagin, or receiving Pagin. Sending RACH may also be referred to as initiating a random access procedure, sending a random access message, or triggering a random access procedure. Random access messages include MSG1, MSG3, and MSGA. Service communication may also be referred to as service transmission, for example, receiving downlink data and sending uplink data.

[0153] It should also be noted that, in this embodiment, the execution order of the steps of the terminal sending an uplink request signal and the step of the terminal selecting to perform the first operation or the second operation based on the first information is not limited to the execution order shown in Figure 3. For example, the terminal may first execute the step of selecting to perform the first operation or the second operation based on the first information, and then execute the step of sending an uplink request signal; or, the terminal may simultaneously execute the step of sending an uplink request signal and the step of selecting to perform the first operation or the second operation based on the first information.

[0154] The first operation includes performing a third operation based on the system information of the first cell, where the third operation includes at least one of the following: monitoring Paging, sending RACH, camping on the target cell, and conducting service communications in the target cell. That is, when the terminal chooses to perform the first operation, the terminal is not subject to any time restrictions on performing operations such as monitoring Paging, sending RACH, camping on the target cell, and conducting service communications in the target cell. For example, the terminal can choose to camp on the target cell at all times.

[0155] The above-mentioned second operation includes executing a fourth operation within a first time window, wherein the fourth operation includes at least one of the following: receiving system information of the first cell, monitoring Paging, sending RACH, residing in the target cell, and performing service communications in the target cell. That is, when the terminal chooses to execute the second operation, the terminal's execution of operations such as receiving system information of the first cell, monitoring Paging, sending RACH, residing in the target cell, and performing service communications in the target cell are subject to time constraints, that is, the terminal only executes operations such as receiving system information of the first cell, monitoring Paging, sending RACH, residing in the target cell, and performing service communications in the target cell within the first time window. When the first time window ends, the terminal can terminate the above-mentioned operations. For example, the terminal can end its residency in the target cell and return to reside in the second cell.

[0156] It should be noted that the execution of the fourth operation within the first time window may also be referred to as the execution of the fourth operation during the operation of a first timer (timer). The timer may also be referred to as a timer.

[0157] In some optional embodiments, after the first time window / first timer expires, the terminal performs at least one of the following:

[0158] Do not receive paging from the first cell;

[0159] Not receiving system messages from the first cell;

[0160] Initiating a Physical Random Access Channel (PRACH) to the first cell is not allowed;

[0161] sending an uplink request signal to the first cell again;

[0162] Perform cell reselection, and the UE reselects back to the second cell.

[0163] It should also be noted that the monitoring of Paging in this embodiment may be monitoring of Paging of the first cell, and the sending of RACH in this embodiment may be sending RACH to the first cell.

[0164] Exemplarily, when the cell signal quality of the terminal's current resident cell (i.e., the second cell) is poor (for example, the cell signal quality index value of the second cell is less than or equal to threshold A), the terminal can send an uplink request signal to wake up the energy-saving cell (i.e., the first cell) and reside in the energy-saving cell, that is, the terminal performs the first operation to improve transmission efficiency; when the cell signal quality of the terminal's current resident cell (i.e., the second cell) decreases but can still be guaranteed to reside in the cell (for example, the cell signal quality index value of the second cell is greater than threshold A and less than or equal to threshold B), if the terminal needs the energy-saving cell to improve transmission efficiency, the terminal can send a US to wake up the energy-saving cell (i.e., the first cell) and reside in the energy-saving cell within the first time window, that is, the terminal performs the second operation to improve transmission efficiency, and returns to the second cell to reside after the first time window ends, which can reduce energy consumption.

[0165] In an embodiment of the present application, the terminal sends an uplink request signal and can choose to perform a first operation or a second operation based on a preset rule, target configuration information and at least one of the system information of the first cell, wherein the first operation includes performing a third operation according to the system information of the first cell, and the third operation includes at least one of the following: monitoring paging, sending a random access channel RACH, residing in the target cell, and performing business communications in the target cell; the second operation includes performing a fourth operation within a first time window, and the fourth operation includes at least one of the following: receiving the system information of the first cell, monitoring Paging, sending RACH, residing in the target cell, and performing business communications in the target cell; that is, the terminal can choose to stay in the energy-saving cell (that is, the target cell) for transmission all the time or stay in the energy-saving cell for transmission only for a period of time (the first time window), which not only improves the flexibility of terminal transmission, but also helps to reduce energy consumption while ensuring transmission efficiency.

[0166] Optionally, the preset rule includes at least one of the following:

[0167] a first preset condition, where the first preset condition is related to a cell signal quality of the first cell;

[0168] a second preset condition, where the second preset condition is related to the cell signal quality of the second cell;

[0506] In this embodiment, the switch corresponding to the first operation can be understood as the switch of the process associated with the first operation, and the switch corresponding to the second operation can be understood as the switch of the process associated with the second operation.

[0507] For example, when the value of the switch corresponding to the first operation is configured as the first value, it indicates that the first operation is "off"; when the value of the switch corresponding to the first operation is configured as the second value, it indicates that the first operation is "on"; when the value of the switch corresponding to the second operation is configured as the first value, it indicates that the second operation is "off"; when the value of the switch corresponding to the second operation is configured as the second value, it indicates that the second operation is "on". For example, one of the first value and the second value can be 0, and the other can be 1.

[0508] In some optional embodiments, the switch corresponding to the first operation and the switch corresponding to the second operation can be indicated by the same switch indication field. For example, if the value of the switch indication field is 01, it means that the first operation is "on" and the second operation is "off"; if the value of the switch indication field is 10, it means that the first operation is "off" and the second operation is "on"; if the value of the switch indication field is 00, it means that the first operation is "on" and the second operation is "on".

[0509] In some optional embodiments, if the above-mentioned switch indication field is not configured, it means that the first operation is "off" and the second operation is "off".

[0510] The threshold corresponding to the first operation can be understood as the threshold of the process associated with the first operation, and the threshold corresponding to the first operation can be used to trigger the first operation. The threshold corresponding to the second operation can be understood as the threshold of the process associated with the second operation, and the threshold corresponding to the second operation can be used to trigger the second operation.

[0512] Exemplarily, the threshold corresponding to the above-mentioned second operation may include but is not limited to the threshold corresponding to at least one of the cell signal quality index value corresponding to the first cell and the cell signal index value corresponding to the second cell.

[0520] The switch corresponding to the first operation in the target configuration information is in an on state;

[0521] The switch corresponding to the second operation in the target configuration information is in an off state.
