Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to an information processing method, device and terminal. Background Art

[0002] In the related art, the user equipment (UE) monitors the physical downlink control channel (PDCCH) only when the media access control (MAC) entity is in the active time. Generally, when the source gNB triggers the UE to execute the early acquisition of the timing advance (TA) value of the candidate cell through the PDCCH order, it is very likely to continue to send the PDCCH order to trigger the UE to re-execute the process of early acquisition of the TA value of the same candidate cell after failure. However, in one case, since the MAC entity of the UE is in the inactive time at this time, the source gNB needs to wait for a period of time until the MAC entity of the UE continues to enter the active time before it can continue to send the PDCCH order, so the source gNB may take a long time to obtain the TA value of the subsequent cell.

It should be noted that in the embodiments of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0052] In order to enable those skilled in the art to better understand the embodiments of the present application, the following description is first made.

[0053] 1. A process for obtaining the timing advance (TA) value of a candidate cell in advance.

[0054] In the related technology, L1 / L2-Triggered Mobility (LTM) based on layer 1 / 2 triggering is introduced. Specifically, the serving base station determines the target cell based on the layer 1 measurement result of the UE, and uses the medium access layer control (MAC) control element (CE) to trigger the UE to switch the primary cell or the primary and secondary cells (or the primary cell group or the secondary cell group) to the target cell (or the target cell group). During the LTM process, the network side will prepare multiple candidate cells in advance, and send the configuration information of the candidate cells to the UE through the radio resource control (RRC) signaling, and when the UE changes the cell, the configuration information of the candidate cells saved by the UE will not be actively released.

[0055] In order to reduce the delay of cell change, during the LTM process, the network (NetWork, NW) can trigger the UE to obtain the timing advance (TA) value of the candidate cell in advance (TA is used for the uplink transmission of the terminal, the purpose is to ensure that the terminal uplink data packet reaches the base station within the desired time). Specifically, the NW sends a PDCCH order to the UE, which carries the identifier of the candidate cell. After receiving the PDCCH order, the UE sends a random access preamble (preamble) to the candidate cell indicated by the PDCCH order, and the candidate cell calculates the TA value of the UE based on the preamble. The PDCCH order that triggers the early acquisition of the TA of the candidate cell will carry the indication information of the candidate cell and the configuration information of the random access timing of the candidate cell. In addition, there is 1 bit in the PDCCH order to clearly configure whether the PRACH is an initial transmission or a retransmission.

[0056] The UE will not maintain the TA value of the candidate cell. The TA value of the candidate cell is maintained by the serving base station. When the serving base station uses MAC CE to trigger the UE to execute LTM, if the serving base station has a valid TA value of the target cell, the TA value will be carried in the media access control unit (LTM cell switch MAC CE) used for LTM cell switching. After receiving the MAC CE, the UE can obtain the TA value of the target cell. Therefore, during the service cell change process, there is no need to trigger the random access (Random Access Channel, RACH) process to the target cell, so that RACH-less based cell switching can be performed.

[0057] Currently, there can only be one RACH process running in a MAC entity. For the RACH process triggered by the PDCCH order to obtain the TA value of the candidate cell in advance, when the UE sends the preamble to the corresponding candidate cell, the RACH process is considered to have ended.

[0058] 2. Discontinuous Reception (DRX) in RRC connected state.

[0059] The purpose of discontinuous reception is to save power. The terminal in DRX state does not need to monitor the control channel. The DRX cycle consists of "On Duration" and "Opportunity for DRX": During the "On Duration" time, that is, the UE's DRX is in the active time, the UE monitors the PDCCH; during the "Opportunity for DRX" time, the UE does not monitor the PDCCH to save power.

[0060] In addition, the network configures an inactivity timer. If a PDCCH indicating a new transmission is received within the onduration, the inactivity timer will be started or restarted to extend the time the UE monitors the PDCCH.

[0061] The MAC entity monitors the PDCCH only during the active period. When the DRX cycle is configured, the active period includes:

[0062] The DRX duration timer (drx-onDurationTimer) or DRX deactivation timer (drx-InactivityTimer), downlink DRX retransmission timer (drx-RetransmissionTimerDL), or uplink DRX retransmission timer (drx-RetransmissionTimerUL), or contention resolution timer (ra-ContentionResolutionTimer) or message B response window (msgB-ResponseWindow) (i.e., the MAC entity is waiting for a message on random access conflict resolution) is running;

[0063] A Scheduling Request (SR) has been sent on the Physical Uplink Control Channel (PUCCH), and the SR is currently in a pending state (i.e., waiting for an uplink grant);

[0064] After the MAC entity successfully receives a random access response (RAR) in response to a "preamble not selected from a contention-based preamble set", it has not yet received a PDCCH indicating an initial transmission and scrambled using a cell radio network temporary identifier (Cell RNTI, C-RNTI).

[0065] The information processing method provided by the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0066] like Figure 2 As shown, the embodiment of the present application provides an information processing method, including:

[0067] Step 201: The terminal starts a first timer at a target time.

[0068] The target time includes the first time or the end time of the second timer:

[0069] The second timer is started at a second moment, and the first moment and the second moment respectively include any one of the following:

[0070] The first item: the moment when the terminal monitors or successfully decodes the first PDCCH command;

[0071] The second item: a time of a first duration from the time when the terminal monitors the first PDCCH command;

[0072] Item 3: the time when the terminal successfully sends the preamble code according to the received first PDCCH command;

[0073] The first PDCCH command is used to trigger the terminal to execute a process of obtaining the timing advance TA value of the candidate cell in advance.

[0074] For the first item above, since the above-mentioned first PDCCH command is used to trigger the terminal to execute the process of obtaining the timing advance TA value of the candidate cell in advance, after the terminal listens to or successfully decodes the first PDCCH command, it executes the process of extracting and obtaining the TA value. In this case, there is a high probability that the network device will continue to send the first PDCCH command to trigger the UE to re-execute the process of obtaining the TA value of the same candidate cell in advance after failing to successfully obtain the TA value of the same candidate cell, or after successfully obtaining the TA value of the candidate cell associated with the first PDCCH command, use the PDCCH command to trigger the terminal to continue to execute the process of obtaining the TA value of other candidate cells in advance. Therefore, starting the first timer at the moment of listening to or successfully decoding the above-mentioned first PDCCH command, and listening to the PDCCH command during the activation time during the operation of the first timer can effectively avoid the delay problem caused by the terminal entering the non-activation time of discontinuous reception or the so-called DRX off period and being unable to monitor the PDCCH, so that the network side has to wait for the next DRX activation time of the terminal to send the PDCCH command.

[0075] For the second item above, optionally, the first duration is determined based on the terminal's processing capability for PDCCH, and optionally, the terminal reports the terminal's processing capability for PDCCH to the network, so that the network configures the first duration based on the terminal's processing capability for PDCCH. Since the terminal needs to process the first PDCCH command accordingly after receiving the first PDCCH command, that is, the terminal cannot monitor the PDCCH command during the process of processing the first PDCCH command accordingly, therefore, the first timer is started at a time of the first duration from the moment when the terminal monitors the first PDCCH command, and the first timer is in the activation time or monitors the PDCCH command during its operation, on the basis of reducing the energy consumption of the terminal, the delay problem caused by the network side having to wait for the next DRX activation time of the terminal to send the PDCCH command is effectively avoided because the terminal cannot monitor the PDCCH during the non-activation time of discontinuous reception or the so-called DRX off period.

[0076] For the third item above, after receiving the first PDCCH command, the terminal needs to send a preamble code based on the first PDCCH command. During this period, the terminal is also unable to monitor the PDCCH command. Therefore, the first timer is started at the moment when the preamble code is successfully sent according to the received first PDCCH command, and the first timer is in the activation time or monitoring the PDCCH command during the operation of the first timer. On the basis of reducing the energy consumption of the terminal, it is effectively avoided that the network side has to wait for the next DRX activation time of the terminal to send the PDCCH command because the terminal enters the non-activation time of discontinuous reception or the so-called DRX off period and cannot monitor the PDCCH. The delay problem caused by this.

[0077] Optionally, the above-mentioned second moment may include the first item or the second item, that is, the duration of the second timer may be determined according to the terminal's processing capability of PDCCH or according to the delay of the terminal sending the preamble code to the candidate cell. After receiving the first PDCCH command, the terminal needs to perform corresponding processing on the first PDCCH command, and will not monitor PDCCH during the processing period. After that, the terminal sends the preamble code according to the first PDCCH command, and will not monitor PDCCH during the period when the terminal sends the preamble code. That is, during the operation of the second timer, the terminal may be in an inactive time or not monitor the PDCCH command. At the end moment of the second timer, that is, after the terminal completes the processing of the first PDCCH command, the first timer is started, and during the operation of the first timer, it is in the active time or monitors the PDCCH command. On the basis of reducing the energy consumption of the terminal, it is effectively avoided that the terminal misses the first PDCCH command sent again by the network device.

[0078] Optionally, when the first moment includes the moment when the terminal listens to or successfully decodes the first PDCCH command, the first moment is specifically the first symbol corresponding to the earliest control resource set in the PDCCH in which the UE is configured to receive the Type1-PDCCH common search space set or the UE-specific search space set, and the first symbol corresponding to the control resource set is located after the last symbol of the first PDCCH command received by the UE and is at least one symbol away from the last symbol of the first PDCCH command received by the UE.

[0079] It is known that the terminal can only monitor PDCCH at the location configured by the control resource set. Therefore, if the first timer is strictly turned on at the precise moment when the terminal monitors or successfully decodes the first PDCCH command, but there is no control resource set at this time, the UE cannot monitor the PDCCH command. Therefore, by monitoring the PDCCH command at the first symbol corresponding to the earliest control resource set in the above-mentioned search space set, it is possible to effectively avoid the delay problem caused by the terminal entering the non-activated time of discontinuous reception or the so-called DRX off period and being unable to monitor PDCCH, which forces the network side to wait for the next DRX activation time of the terminal to send the PDCCH command, thereby reducing unnecessary power consumption.

[0080] Optionally, when the first moment includes the moment when the terminal successfully sends the preamble code according to the first PDCCH command received, the first moment is specifically the first symbol corresponding to the earliest control resource set in the PDCCH in which the UE is configured to receive the Type1-PDCCH common search space set or the UE-specific search space set, and the first symbol corresponding to the control resource set is located after the last symbol of the physical random access channel (Physical Random Access Channel, PRACH) opportunity when the UE sends the preamble code according to the first received PDCCH command, and is at least one symbol away from the last symbol of the PRACH opportunity when the UE sends the preamble code according to the first received PDCCH command.

[0081] It is known that the terminal can only monitor PDCCH at the location configured in the control resource set. Therefore, if the first timer is strictly turned on at the precise moment when the terminal successfully sends the preamble code according to the received first PDCCH command, but there is no control resource set at this time, the UE cannot monitor the PDCCH command. Therefore, by monitoring the PDCCH command at the first symbol corresponding to the control resource set, it can effectively ensure that the terminal monitors the first PDCCH command at the PDCCH timing, and thus effectively avoid the delay problem caused by the terminal entering the non-activated time of non-continuous reception or the so-called DRX off period and being unable to monitor PDCCH, which makes the network side have to wait for the next DRX activation time of the terminal to send the PDCCH command, thereby reducing unnecessary power consumption.

[0082] In an embodiment of the present application, the unit of the above-mentioned first moment or second moment can be seconds, milliseconds, microseconds, frames, subframes, orthogonal frequency division multiplexing (OFDM) symbols; exemplarily, the UE starts the first timer or the second timer at the first symbol, the first time slot, or the first subframe after the terminal listens to or successfully decodes the first PDCCH command.

[0083] In an embodiment of the present application, the unit of the above-mentioned first duration can be seconds, milliseconds, microseconds, frames, subframes, orthogonal frequency division multiplexing (OFDM) symbols, and the first duration can be configured by the network or agreed upon by a protocol.

[0084] The length units of the first timer and the second timer may be seconds, milliseconds, microseconds, frames, subframes, or OFDM symbols.

[0085] Exemplarily, the end time of the second timer may be the first symbol after the second timer expires, or the first time slot after the second timer expires, or the first subframe after the second timer expires, etc.

[0086] The first timer in the embodiment of the present application can also be described as a first duration, and the target time is the starting time of the first duration. The first timer can also be described as a first time window, and the target time is the starting time of the first time window.

[0087] Optionally, when the UE starts the second timer, if the first timer is running, the first timer is stopped.

[0088] Step 202: During the operation of the first timer, the terminal performs at least one of the following:

[0089] The first item: controlling the media access control MAC entity of the terminal to be in the activation time;

[0090] Item 2: monitor the physical downlink control channel PDCCH;

[0091] Optionally, for the second item above, during the operation of the first timer, the terminal monitors the PDCCH regardless of whether the current time is an activation time.

[0092] Optionally, the monitoring of a physical downlink control channel PDCCH includes monitoring a PDCCH used for random access.

[0093] Exemplarily, the terminal monitoring the PDCCH for random access can be understood as the UE monitoring the downlink control information (Downlink Control Information, DCI) format (format) 1_0 or monitoring the PDCCH encrypted by the cell radio network temporary identification (Cell RNTI, C-RNTI). If the current time is not activated, the UE only monitors DCI format 1_0 or only monitors the PDCCH encrypted by the C-RNTI.

[0094] The first timer may be an existing timer, such as a discontinuous reception-inactivity timer (drx-InactivityTimer), or may be a newly introduced timer.

[0095] In an embodiment of the present application, the terminal starts a first timer at a target time, for example, at the moment of receiving the first PDCCH command for triggering the terminal to execute the process of obtaining the timing advance TA value of the candidate cell in advance, or at the moment after receiving the first PDCCH command for the first duration, or at the moment when the terminal successfully sends the preamble code according to the received first PDCCH command, the first timer is started, and during the operation of the first timer, the MAC entity of the terminal is controlled to be in the activation time; and the physical downlink control channel PDCCH is monitored. Through the above scheme, it can be ensured that the MAC entity of the terminal is still in the activation time or continues to monitor the PDCCH within a certain duration after the network side device sends the above first PDCCH command. This avoids the situation that after the network side device sends the above first PDCCH command, the MAC entity of the terminal enters an inactive state and needs to wait for the MAC entity of the terminal to be in the activation time again before sending the PDCCH command for triggering the process of the timing advance TA value of the candidate cell, thereby reducing the time for the network side to obtain the TA value of the candidate cell.

[0096] Optionally, the method of the embodiment of the present application further includes:

[0097] During the running of the second timer, the terminal performs at least one of the following:

[0098] The terminal does not monitor the PDCCH or does not monitor the PDCCH command;

[0099] In the case where there is no target trigger information during the running of the second timer, controlling the media access control MAC entity of the terminal to be in an inactive time;

[0100] Among them, the target trigger information is information other than the first PDCCH command and is used to trigger the terminal's MAC entity to be in the activation time, specifically including all mechanisms specified in the protocol that trigger / cause / result in the terminal's MAC entity being in the activation time.

[0101] As an example, there is target trigger information at moment n during the operation of the second timer, and the target trigger information includes that the UE received a DRX command media access layer control unit (DRX Command MAC CE) or a long DRX command media access layer control unit (Long DRX Command MAC CE) 4 ms before moment n, or the UE sent a scheduling request; or the UE has a configured grant at moment n and sends uplink information; or at moment n, the UE's drx-ondurationTimer is running, etc.

[0102] In an embodiment of the present application, the duration of the above-mentioned second timer is determined according to the terminal's processing capability of PDCCH. After receiving the first PDCCH command, the terminal needs to perform corresponding processing on the first PDCCH command, and will not monitor the PDCCH command during the processing, that is, during the operation of the second timer, the terminal can be in an inactive time or not monitor the PDCCH command. At the end time of the second timer, that is, after the terminal completes the processing of the first PDCCH command, the first timer is started, and during the operation of the first timer, it is in an active time or monitors the PDCCH command. This effectively avoids the terminal from missing the first PDCCH command sent again by the network device on the basis of reducing the energy consumption of the terminal.

[0103] Optionally, the terminal not monitoring the PDCCH or not monitoring the PDCCH command includes:

[0104] When the target triggering information does not exist during the running of the second timer, the terminal does not monitor the PDCCH or does not monitor the PDCCH command.

[0105] Here, when there is no target trigger information during the operation of the second timer, not monitoring the PDCCH or not monitoring the PDCCH command can effectively save power consumption of the terminal.

[0106] Optionally, the duration of the second timer is determined according to at least one of the following:

[0107] The terminal's ability to process PDCCH;

[0108] Delay information of terminal uplink transmission;

[0109] The processing power or computing power on the network side;

[0110] Network side interface delay; the network side interface includes at least one of the F1, Xn and N2 interfaces.

[0111] Cell quality information of the terminal;

[0112] Network implementation.

[0113] In the embodiment of the present application, the duration of the second timer may be a network configuration or a protocol agreement. For example, the network configures the duration of the second timer according to the PDCCH processing capability or cell quality information reported by the UE or the network implementation.

[0114] The duration of the second timer is set through the above content to determine the processing time required by the terminal after receiving the first PDCCH command, that is, to determine the duration during which the terminal cannot monitor the PDCCH command, thereby effectively saving power consumption of the terminal.

[0115] Optionally, the method of the embodiment of the present application further includes:

[0116] After receiving a discontinuous reception DRX command media access layer control unit MAC CE or a long DRX command media access layer control unit MAC CE, perform at least one of the following:

[0117] Stop or not stop the first timer, where not stopping the first timer can be understood as allowing the terminal to continue to execute the behavior when the first timer is running, such as the MAC entity of the terminal continues to maintain the activation time or the terminal continues to monitor the PDCCH;

[0118] Stop the first timer, and control the media access control MAC entity of the terminal to enter an inactive time or not monitor the PDCCH or PDCCH command;

[0119] Do not stop the first timer, and control the MAC entity of the terminal to enter an inactive time and not monitor the PDCCH;

[0120] The first timer is not stopped, and the MAC entity of the terminal is controlled to enter an inactive time and monitor the PDCCH or a PDCCH command.

[0121] Stopping the first timer in the embodiment of the present application may also be described as exiting and resetting the first time window or the first duration.

[0122] Optionally, the method of the embodiment of the present application further includes:

[0123] After receiving the first control signaling, the terminal stops the first timer and performs the target operation in the absence of target triggering information;

[0124] Alternatively, after the first timer expires and in the absence of target trigger information, the target operation is performed;

[0125] The target operation includes at least one of the following:

[0126] Control the MAC entity of the terminal to enter the inactive time;

[0127] Stop monitoring PDCCH or PDCCH command;

[0128] The target trigger information is information other than the first PDCCH command and used to trigger the MAC entity of the terminal to be in the activation time;

[0129] The first control signaling is used to indicate that the network side will not trigger the terminal to continue to execute the process of obtaining the TA value of the candidate cell in advance or the UE does not need to continue to monitor the PDCCH command that triggers the execution of the process of obtaining the TA value of the candidate cell in advance. The first control signaling can be MAC CE or DCI.

[0130] In an embodiment of the present application, after receiving the first control signaling, the terminal stops the first timer and performs the target operation in the absence of target trigger information; or, after the first timer expires and in the absence of target trigger information, the target operation is performed, which can effectively reduce the power consumption of the terminal.

[0131] Optionally, the method of the embodiment of the present application further includes:

[0132] After the first timer expires (expired), and if a target condition is met, the terminal uses a short DRX cycle;

[0133] Alternatively, after the first timer expires and the target condition is not met, the terminal uses a long DRX cycle;

[0134] The target condition includes that there is no target trigger information, and during the operation of the first timer, the MAC entity of the terminal is in the activation time and a short DRX cycle is configured;

[0135] The target trigger information is information other than the first PDCCH command and is used to trigger the MAC entity of the terminal to be in the activation time.

[0136] Optionally, the configuration information of the first timer is configured for any one of the following or agreed upon by a protocol:

[0137] terminal;

[0138] Terminal type;

[0139] Distributed Unit (DU);

[0140] Centralized Unit (CU);

[0141] DU and CU;

[0142] Frequency;

[0143] Frequency range;

[0144] Candidate cell;

[0145] The configuration information of the first timer includes at least one of the duration of the first timer and the offset of the first timer.

[0146] In an embodiment of the present application, the offset of the first timer is used to indicate the offset value of the start time of the first timer relative to the first preset time. For example, the first preset time is the time when the terminal monitors or successfully decodes the first PDCCH command. The offset of the first timer is the first duration.

[0147] Exemplarily, the length of the first timer is configured for a terminal or a terminal type (UE type), and the length of the first timer corresponding to a UE or the same UE type is the same, that is, regardless of whether the candidate cell and the current service cell are of the same DU or different DUs, or, the candidate cell and the current service cell are of the same frequency or different frequencies, or, the candidate cell and the current service cell are of the same frequency band or different frequency bands, the lengths of the first timers corresponding to different candidate cells are the same.

[0148] Exemplarily, the length of the above-mentioned first timer is configured for DU or CU, that is, the network side will configure multiple first timer lengths for the UE, corresponding to different DUs or different CUs respectively. For example, UE#1 has four candidate cells (cell#1, cell#2, cell#3, cell#4), the CU corresponding to the current serving cell and the candidate cell cell#1 is CU#1, and the corresponding DU is DU#1, the CU corresponding to the candidate cell cell#2 is CU#1, and the corresponding DU is DU#2, the CU corresponding to the candidate cell cell#3 is CU#1, and the corresponding DU is DU#3, the CU corresponding to the candidate cell cell#4 is CU#2, and the corresponding DU is DU#1, then the length configuration of the first timer received by the UE has 4 values, corresponding to CU#1&DU#1, CU#1&DU#2, CU#1&DU#3, and CU#2&DU#1 respectively; another implementation method is that the network side configures The network side configures or agrees on the length values ​​of two first timers (for the scenario of intra-CU switching). When the candidate cell and the serving cell correspond to the same DU (i.e., intra-DU), the UE applies the first length, otherwise the second length is applied; or the network side configures or agrees on the length values ​​of three first timers (for the scenario of different CU (inter-CU) switching), corresponding to the cases of intra-CU&intra-DU, intra-CU&inter-DU, and inter-CU respectively. When the candidate cell and the serving cell correspond to the same DU and CU (i.e., intra-CU and intra-DU), the UE applies the first length; when the candidate cell and the serving cell correspond to the same CU but different DUs (i.e., intra-CU and inter-DU), the UE applies the second length; when the candidate cell and the serving cell correspond to different CUs, the third length is applied.

[0149] Exemplarily, the length of the above-mentioned first timer is configured for the frequency point, that is, the network side will configure multiple first timer lengths for the UE, corresponding to different frequency points respectively. For example, UE#1 has three candidate cells (cell#1, cell#2, cell#3), the frequency point corresponding to the current service cell and the candidate cell cell#1 is freq#1, the candidate cell cell#2 corresponds to freq#2, and the frequency point corresponding to the candidate cell cell#3 is freq#3. Then, the length configuration of the first timer received by the UE has 3 values, corresponding to freq#1, freq#2, and freq#3 respectively; another implementation method is that the network side configures or the protocol agrees on the length values ​​of the two first timers. When the candidate cell and the service cell correspond to the same frequency point (ie, intra-freq), the UE applies the first length, otherwise the second length is applied.

[0150] Exemplarily, the length of the above-mentioned first timer is configured for the frequency range, that is, the network side will configure multiple first timer lengths for the UE, corresponding to different frequency bands. For example, UE#1 has three candidate cells (cell#1, cell#2, cell#3), and the frequency corresponding to the current service cell and the candidate cell cell#1 is FR1, and the candidate cells cell#2 and cell#3 correspond to FR2. Then, the length configuration of the first timer received by the UE has two values, corresponding to FR1 and FR2 respectively; another implementation method is that the network side configures or the protocol agrees on the length values ​​of the two first timers. When the candidate cell and the serving cell correspond to the same frequency band, the UE applies the first length, otherwise the second length is applied.

[0151] Exemplarily, the length of the first timer is configured for the candidate cell, that is, the network side configures a first timer length for each candidate cell of the UE. When the UE executes the process of obtaining TAvalue in advance for different candidate cells, the first timer is set to the corresponding length.

[0152] like Figure 3 As shown, when the UE receives the first PDCCH order, it starts the first timer, and during the running of the first timer, the MAC entity of the UE is in the active time.

[0153] Optionally, the configuration information of the second timer is configured for any one of the following or agreed upon by a protocol:

[0154] terminal;

[0155] Terminal type;

[0156] DU;

[0157] CU;

[0158] DU and CU;

[0159] Frequency;

[0160] Frequency range;

[0161] Candidate cell;

[0162] The configuration information of the second timer includes at least one of a duration of the second timer and an offset of the second timer.

[0163] In an embodiment of the present application, the offset of the second timer is used to indicate the offset value of the start time of the second timer relative to the second preset time. For example, the second preset time is the time when the terminal monitors or successfully decodes the first PDCCH command. The offset of the second timer is the first duration.

[0164] like Figure 4 As shown, when the UE receives the first PDCCH order, the second timer is turned on, and during the operation of the second timer, if there is no target trigger information that causes the UE's MAC entity to be in the activation time, the UE's MAC entity is not in the activation time; after the second timer expires, the first timer is turned on, and during the operation of the first timer, the UE's MAC entity is in the activation time.

[0165] In an embodiment of the present application, the terminal starts a first timer at a target time, for example, at the moment of receiving the first PDCCH command for triggering the terminal to execute a process of obtaining the timing advance TA value of the candidate cell in advance, or at the moment after receiving the first PDCCH command for the first duration, or at the moment when the terminal successfully sends the preamble code according to the received first PDCCH command, the first timer is started, and during the operation of the first timer, the MAC entity of the terminal is controlled to be in the activation time; and the physical downlink control channel PDCCH is monitored. Through the above scheme, it can be ensured that the MAC entity of the terminal is still in the activation time or continues to monitor the PDCCH within a certain duration after the network side device sends the above first PDCCH command. This avoids the situation that after the network side device sends the above first PDCCH command, the MAC entity of the terminal enters the inactive time and needs to wait for the MAC entity of the terminal to be in the active time again before sending the PDCCH command for the process of triggering the timing advance TA value of the candidate cell, thereby reducing the time for the network side to obtain the TA value of the candidate cell.

[0314] In the above scheme of the embodiment of the present application, the terminal starts the first timer at the target time, for example, at the moment of receiving the first PDCCH command for triggering the terminal to execute the process of obtaining the timing advance TA value of the candidate cell in advance, or at the moment after receiving the first PDCCH command for the first duration, or at the moment when the terminal successfully sends the preamble code according to the received first PDCCH command, the first periodic device is started, and the MAC entity of the terminal is controlled to be in the activation time during the operation of the first timer; and the physical downlink control channel PDCCH is monitored. Through the above scheme, it can be ensured that the MAC entity of the terminal is still in the activation time or continues to monitor the PDCCH within a certain duration after the network side device sends the above first PDCCH command, so as to avoid the need to wait for the MAC entity of the terminal to be in the activation time again before sending the PDCCH command for the process of triggering the timing advance TA value of the candidate cell due to the MAC entity of the terminal entering the inactive time after the network side device sends the above first PDCCH command, thereby reducing the time for the network side to obtain the TA value of the candidate cell.
