[0169] FIG. 2A is an interaction diagram of an information processing method according to an embodiment of the present disclosure. As shown in FIG. 2A, the embodiment of the present disclosure relates to an information processing method, and the method comprises:

[0170] In step S2101, the first network device sends configuration information to the terminal.

[0171] In some embodiments, the configuration information is used to configure the configuration of at least one candidate cell. Optionally, the configuration information includes one or more candidate configurations. Each candidate configuration includes one or more candidate cells. It should be noted that the embodiments of the present disclosure are described by taking the candidate cell as an example. In another embodiment, the candidate cell can also be referred to as a candidate cell group.

[0172] In some embodiments, the candidate cell (candidate cell group) can also be referred to as a candidate target cell (candidate target cell group)

[0173] In some embodiments, the configuration information is carried in RRC (Radio Resource Control) signaling or other signaling, which is not limited by the embodiments of the present disclosure.

[0174] In some embodiments, after the configuration information is configured for the terminal, it can be used for any one or more of the following situations: cell switching, cell addition, and cell change.

[0175] In some embodiments, after the configuration information is configured for the terminal, it can be used for any one or more of the following situations: cell group addition and cell group change.

[0176] In some embodiments, the configuration information is used to configure the configuration of at least one candidate cell, and the candidate configuration can be used for multiple mobility operations, including but not limited to any one or more of the following mobility operations: Conditional (conditional) LTM

[0177] LTM;

[0178] CHO (Conditional Handover, conditional handover);

[0179] CPA (Conditional PSCell Addition, conditional primary secondary cell (or cell group) addition);

[0180] CPC (Conditional PSCell Change, conditional primary secondary cell (or cell group) change);

[0181] Subsequent CHO (Conditional Handover, conditional handover);

[0195] LTM;

[0196] Subsequent LTM;

[0197] Subsequent Conditional LTM.

[0198] Optionally, the first network device can control the terminal to change the cell in the multiple candidate cells included in the configuration information through signaling.

[0199] Optionally, the terminal changes the configuration of the cell to the configuration of the candidate cell corresponding to the trigger condition when the trigger condition configured by the first network device or agreed by the protocol is met. For example, the execution condition 1 is associated with the candidate configuration 1 (the association can be realized by corresponding to the same configuration identifier), wherein the execution condition 1 is associated with the measurement event A3, and when the measurement result of the terminal meets the measurement event A3 associated with the execution condition 1, the terminal applies the candidate configuration 1 associated with the execution condition 1.

[0200] For example, the terminal applies the candidate configuration 1 associated with the execution condition 1, that is, the terminal changes the configuration of the serving cell to the candidate configuration 1 associated with the execution condition 1, and accesses the candidate cell 1.

[0201] In some embodiments, the network device can update, modify, or delete the configuration of the candidate cell configured for the terminal.

[0202] At step S2102, the terminal receives the configuration information sent by the first network device.

[0203] In the embodiments of the present disclosure, after receiving the configuration information sent by the first network device, the terminal can determine the configuration of the corresponding candidate cell according to the configuration information.

[0204] It should be noted that after receiving the configuration information sent by the first network device, the terminal needs to return response information to the first network device, and the response information is used to reply that the first network device has received the configuration information.

[0205] Optionally, the configuration information of the first network device is RRCReconfiguration, and the response information of the terminal is RRCReconfigurationComplete.

[0206] At step S2103, the second network device sends a second message.

[0207] In some embodiments, the second network device sends the second message to the first network device.

[0208] In some embodiments, the second network device is not connected with the terminal. In the embodiments of the present disclosure, the second network device is not a cell providing service for the terminal, or it can also be understood that the second network device can be a candidate cell providing service for the terminal, or it can also be understood that the second network device can be a candidate cell connected with the terminal.

[0209] In some embodiments, the second network device covers the candidate cell, and the candidate cell includes at least one of the following:

[0210] (1) A cell corresponding to the terminal based on the condition triggered mobility.

[0211] (2) A cell used for handover of the terminal.

[0212] (3) A neighbor cell.

[0213] Optionally, in the embodiments of the present disclosure, the candidate cell is any one or more of SPcell, PCell, PSCell, and SCell.

[0214] Optionally, in the embodiments of the present disclosure, the candidate cell group is any one or more of MCG and SCG.

[0215] Optionally, for the TA related information of the SCell included in the candidate configuration, the network device can selectively include it in the sent first message.

[0216] In some embodiments, the second message comprises a TA corresponding to the second network device and / or time information corresponding to the TA. In the embodiments of the present disclosure, the TA is used to indicate the time delay caused by the transmission path when the terminal transmits in uplink. Optionally, if the terminal needs to transmit uplink data, it needs to be transmitted according to the TA to ensure that the uplink data reaches the network device at the expected time.

[0217] In some embodiments, the time information comprises at least one of the following:

[0218] (1) TAT duration; the TAT duration is used to indicate the effective duration of the TA value. In some embodiments, the TAT duration is the timing duration of a specified timer. If the timer expires, the TA value is invalid.

[0219] (2) TAT adjustment value, which is used to adjust the TAT duration.

[0220] In the embodiments of the present disclosure, the TAT adjustment value can increase or decrease the TAT duration, which is not limited in the embodiments of the present disclosure.

[0221] (3) Effective time of the TA value.

[0222] In some embodiments, the effective time of the TA value can be an absolute time, and the effective time of the TA value is the time information of the serving cell, which can be indicated by UTC time, SFN and subframe time. The effective time is used to indicate the time when the terminal maintains the TA of the candidate cell (or the TAG corresponding to the candidate cell) and starts the TAT corresponding time.

[0223] (4) TAT (timeAlignmentTimer).

[0224] It should be noted that in the embodiments of the present disclosure, the terminal can send a random access preamble to the candidate cell, and the candidate cell can determine the TA value and / or the time information corresponding to the TA based on the received random access preamble sent by the terminal. Subsequently, the second access network device corresponding to the candidate cell can send a second message comprising the TA value and / or the time information corresponding to the TA to the first access network device.

[0225] In some embodiments, the second message can further comprise at least one of the following messages:

[0226] (1) The candidate cell identifier corresponding to the second network device.

[0227] (2) Configuration identifier corresponding to the candidate cell. The configuration identifier is used to indicate the configuration corresponding to the candidate cell, which is associated with the configuration to be used when the UE accesses the candidate cell;

[0228] (3) Node identity of the candidate cell corresponding to the second network device.

[0229] Optionally, the node identity is, for example, a CU (Cellular Unit) identity; a DU (Data Unit) identity.

[0230] (4) Candidate cell TAG identity.

[0231] Optionally, the TAG identity is used to identify the TAG corresponding to the candidate cell, which is different from the existing TAG identity used to identify the sPCell and / or SCell, and is a TA identity used to indicate the candidate cell that needs to maintain TA.

[0232] (5) Terminal identity.

[0233] In some embodiments, for the CU and DU separation scenario of the second network device, referring to FIG. 2B, the DU where the candidate cell is located acquires the TA value of the terminal in the candidate cell and / or the time information corresponding to the TA value, and sends the TA value and / or the time information corresponding to the TA value to the CU of the candidate cell. The CU of the candidate cell forwards the TA value and / or the time information corresponding to the TA value to the CU of the serving cell through the second message. The CU of the serving cell can integrate the TA value and / or the time information corresponding to the TA value contained in the second message received from the CUs of different candidate cells, and generate the TA information of one or more candidate cells (or target cells) sent to the terminal based on this, and send it to the terminal. Alternatively, the CU of the serving cell can also send the second message sent by the CU of a certain candidate cell to the UE after receiving it.

[0234] In some embodiments, the first access network device triggers the process of the terminal sending a random access preamble to the candidate cell.

[0235] In some embodiments, the process of the terminal sending a random access preamble to the candidate cell belongs to the early RACH process.

[0236] Step S2104: The first network device receives the second message sent by the second network device.

[0237] In the embodiments of the present disclosure, after the first network device receives the second message sent by the second network device, the TA value corresponding to each candidate cell and / or the time information corresponding to the TA can be determined.

[0238] Step S2105: The first network device sends a first message.

[0239] In some embodiments, the first message is used to configure TA information of at least one candidate cell. Optionally, the first message is a PHY (Physical Layer) layer signal. Optionally, the first message is a MAC (Media Access Control) layer message. For example, the MAC CE layer message is a MAC CE message. Optionally, the MAC CE message includes at least one of a RAR (Random Access Response) and a MAC CE. The RAR is a RAR corresponding to a preamble of the terminal received by the candidate cell. Optionally, the first message is an RRC message.

[0240] In some embodiments, the TA information is used to indicate a TA of one or more candidate cells. The candidate cell is used for mobility operation of the terminal.

[0241] In some embodiments, the TA information includes at least one of:

[0242] (1) a cell identity, the cell identity being used to indicate a candidate cell corresponding to the TA information.

[0243] (2) a configuration identity, the configuration identity being used to indicate a configuration of a candidate cell corresponding to the TA information.

[0244] (3) a node identity, the node identity being used to indicate a node of a candidate cell corresponding to the TA information.

[0245] In some embodiments, the node indicates at least one of a CU identity or a DU identity.

[0246] (4) a TAG identity, the TAG identity being used to identify a TAG of a candidate cell corresponding to the TA information.

[0247] In some embodiments, the TAG is different from a TAG identity used to identify a sPCell and / or an SCell, and the TAG in the embodiments of the present disclosure is a TA identity used to indicate a candidate cell requiring maintenance of a TA.

[0248] (5) a TA value.

[0249] (6) time information corresponding to the TA value.

[0250] The time information corresponding to the TA value is similar to the time information in the above embodiments, and is not described here again.

[0251] Step S2106, the terminal receives the first message.

[0252] In some embodiments, the terminal receives the first message sent by the first access network device.

[0253] It should be noted that steps S2103 to S2106 in the embodiments of the present disclosure are described by taking an example in which the first access network device receives the message sent by the second access network device and then sends the received message to the terminal. In another embodiment, the second access network device can also send the message directly to the terminal. Referring to FIG. 2C, the method includes: the second access network device sends the RAR to the terminal, the terminal receives the RAR sent by the second access network device, and the terminal obtains the TA of the second access network device based on the RAR. It should be noted that the terminal can also maintain the TA of the second network device in the embodiments of the present disclosure. The scheme in which the terminal maintains the TA of the second network device is similar to steps S2107-S2108.

[0254] In step S2107, the terminal stores the TA information of the at least one candidate cell.

[0255] In the embodiments of the present disclosure, after the terminal receives the TA information of the at least one candidate cell included in the first message, the terminal can store the obtained TA information of the at least one candidate cell.

[0256] In step S2108, the terminal starts the TAT corresponding to the candidate cell.

[0257] In the embodiments of the present disclosure, the terminal starts the TAT corresponding to the candidate cell based on the first message.

[0258] In some embodiments, the terminal starts the corresponding TAT based on the time information corresponding to the TA value. In the embodiments of the present disclosure, if the TA information does not include the time information corresponding to the TA value, the terminal starts the TAT corresponding to the candidate cell based on the preconfigured TAT length or the default TAT length when receiving the first message.

[0259] In some embodiments, the terminal starts the corresponding TAT based on the TAT length configured by the network device. In the embodiments of the present disclosure, if the TA information includes the time information corresponding to the TA value, the terminal starts the TAT based on the time information corresponding to the TA value when receiving the first message.

[0260] Optionally, if the time information includes the TAT adjustment value, the terminal needs to adjust the TAT length preconfigured by the network device based on the TAT adjustment value when maintaining the TA of the candidate cell and starting the TAT.

[0261] Optionally, the TAT length included in the time information is used to indicate the duration of the TAT started by the terminal when maintaining the TA of the candidate cell.

[0262] Optionally, the time information comprises a validity time of the TA value, the validity time of the TA value can be an absolute time, the validity time of the TA value is time information of the serving cell, and the time information of the serving cell can be indicated by a UTC (Universal Time Coordinated) time, a SFN (System Frame Number), and a subframe time. The validity time of the TA value is used to indicate a time at which the terminal starts a TAT corresponding to the candidate cell (or a TAG corresponding to the candidate cell) when the terminal maintains the TA of the candidate cell (or the TAG corresponding to the candidate cell), and the terminal needs to start the TAT corresponding to the candidate cell (or the TAG corresponding to the candidate cell) at the time. The time is generally earlier than a current time, and therefore when the terminal receives the TA, the terminal considers that the TAT corresponding to the candidate cell (or the TAG corresponding to the candidate cell) has been running for a time length, and the time length is a difference between the current time and a time at which the TA is acquired.

[0263] Optionally, the TAT corresponding to each candidate cell expires, and the terminal deletes the TA information corresponding to the candidate cell stored by the terminal. It should be noted that the terminal can send information to the first network device to inform the first network device that the TAT corresponding to the candidate cell (or the TAG corresponding to the candidate cell) expires, and the TA value is invalid, so that the first network device can reinitiate the TA acquisition process.

[0264] It should be noted that the terminal needs to maintain the TAT corresponding to each candidate cell based on the first message.

[0265] In some embodiments, the TAT corresponding to each candidate cell is maintained based on the first message, and the TAT corresponding to each candidate cell is maintained based on the first message includes any one of the following:

[0266] (1) A TAT corresponding to a TAG of each candidate cell is maintained.

[0267] (2) A TAT corresponding to each candidate cell is maintained.

[0268] (3) A TAT corresponding to a candidate cell satisfying a first condition is maintained.

[0269] In some embodiments, the first condition includes at least one of the following:

[0270] (1) A measurement result of the candidate cell is greater than a threshold value;

[0271] (2) A second condition associated with the candidate cell corresponds to at least two handover events, and at least one handover event in the at least two handover events is satisfied.

[0272] Optionally, a specific TAT corresponding to the candidate cell satisfying the first condition is maintained.

[0273] Step S2109, the terminal determines that the target cell satisfies the third condition, and the TA corresponding to the target cell is valid, and switches to the target cell.

[0274] The target cell is one of the at least one candidate cell.

[0275] In some embodiments, the terminal determines that the target cell satisfies the third condition, and switches to the target cell, which can be implemented by any one or more of the following mobility procedures:

[0276] Conditional trigger-based mobility: including but not limited to any one or more of Conditional LTM, CHO, CPA, CPC, Subsequent Conditional LTM, Subsequent CHO, Subsequent CPAC

[0277] Network device instruction trigger-based mobility includes but is not limited to at least one of the following: LTM, Subsequent LTM, Handover, switching, PSCell addition, PSCell change, SCell addition, SCell change, SCell deletion, SCell activation and / or deactivation, SCG activation and / or deactivation, MCG activation and / or deactivation.

[0278] In some embodiments, the third condition includes at least one of the following:

[0279] (1) The target cell satisfies the second condition.

[0280] For example, the target cell satisfies the second condition, wherein the second condition is the second condition corresponding to the candidate configuration in the configuration information in S2101, and the candidate cell is the cell corresponding to the candidate configuration.

[0281] For example, the third condition corresponds to conditional trigger-based mobility:

[0282] Optionally, the second condition includes at least one of the following switching events:

[0283] Trigger events based on cell-level measurement results;

[0284] Trigger events based on beam-level measurement results;

[0285] Trigger events based on L3 measurement;

[0286] Trigger events based on L1 measurement.

[0287] The following illustrates the switching events:

[0288] CondEvent A3: Conditional reconfiguration candidate becomes amount of offset better than PCell / PSCell;

[0289] CondEvent A4: Conditional reconfiguration candidate becomes better than absolute threshold where condEventA4 can also be used for current PSCell (i.e., in case it is configured as candidate PSCell for CondEvent A4 evaluation) for CHO with candidate SCG(s) case;

[0290] CondEvent A5: PCell / PSCell becomes worse than absolute threshold1 AND Conditional reconfiguration candidate becomes better than another absolute threshold2;

[0291] CondEvent D1: Distance between UE and a reference location referenceLocation1 becomes larger than configured threshold distanceThreshFromReference1 and distance between UE and a reference location referenceLocation2 of conditional reconfiguration candidate becomes shorter than configured threshold distanceThreshFromReference2;

[0295] Event LTM4: Beam of candidate cell becomes better than absolute threshold;

[0296] Event LTM5: Beam of serving cell becomes worse than absolute threshold1 AND Beam of candidate cell becomes better than another absolute threshold2.

[0297] (Conclusion A3: The offset of the conditional reconfiguration candidate cell is better than the PCell / PCell;

[0298] Conclusion A4: The conditional reconfiguration candidate cell becomes better than an absolute threshold, Conclusion tA4 can also be used for the current PSCell (i.e. if it is configured as a candidate PSCell for condEventA4 evaluation) for CHO with candidate SCG;

[0299] Conclusion A5: The PCell / PCell is 1 worse than an absolute threshold, the conditional reconfiguration candidate cell is 2 better than another absolute threshold;

[0300] CondEvent D1: The distance of the UE to the reference location referenceLocation1 is greater than a configured threshold distanceThreshFromReference1, the distance of the UE to the reference location referenceLocation2 of the conditional reconfiguration candidate cell is less than a configured threshold distanceThreshFromReference2;

[0301] Conclusion D2: The distance between the UE and the mobile reference location based on the moving reference location and its corresponding satellite ephemeris and SIB19 epoch broadcasted by the serving cell is greater than a configured threshold distanceThreshFromReference1, the distance between the UE and the mobile reference location determined based on the referenceLocation2 of the conditional reconfiguration candidate cell is less than a configured threshold distanceThreshFromReference2;

[0302] Event LTM2: The serving cell beam is worse than an absolute threshold;

[0303] Event LTM3: The candidate cell beam is better than the serving cell beam;

[0304] Event LTM4: The candidate cell beam is better than an absolute threshold;

[0305] Event LTM5: The serving cell beam is d1 worse than an absolute threshold, the candidate cell beam is d2 better than another absolute threshold.

[0306] (2) The target cell is indicated by the network equipment.

[0307] Exemplarily, the third condition corresponds to network indication based mobility:

[0308] In some embodiments, the terminal sends a random access preamble to the target cell, and the random access preamble is used to access the target cell.

[0309] It should be noted that the embodiments of the present disclosure are described by taking the terminal determining that the target cell meets the third condition and the TA corresponding to the target cell being valid, and switching to the target cell as an example. In another embodiment, if the TA of the target cell is invalid, the terminal needs to perform H0-based RACH.

[0360] In some embodiments, the embodiment of the present disclosure relates to an information processing method, and the method comprises: a serving cell sends TA information of a candidate cell to a terminal.

[0361] In some embodiments, the serving cell sends TA related information (by the first information) of one or more candidate cells (or target cells) to the UE; the UE maintains TA of the one or more candidate cells (or target cells) based on the TA information of the one or more candidate cells (or target cells) sent by the serving cell, and when the UE needs to access any one or more of the candidate cells (or target cells) later, the UE performs RACH-less handover using the TA value maintained for the corresponding cell.

[0362] Optionally, RACH-less is to reduce mobility interruption time by not performing (or removing) RACH procedure during mobility events (including handover and / or pcell change / addition).

[0363] In some embodiments, the TA information of the candidate cell (target cell) can be any one or more of the following candidate cells (target cells) configured by the network side for the UE: one or more candidate cells (target cells) corresponding to the conditionally triggered mobility; one or more candidate cells of C-LTM; target cell of handover configured by the network side for the UE; one or more neighbor cells indicated by the network side.

[0364] In some embodiments, the TA related information includes any one or more of the following information (wherein one or more candidate cells (target cells) can correspond to one TA related information):

[0365] Corresponding candidate cell (or target cell) identifier;

[0366] Corresponding configuration identifier, the configuration identifier is used to indicate the configuration corresponding to the candidate cell (or target cell), which is associated with the configuration needed to be used when the UE accesses the candidate cell (or target cell);

[0367] Node identifier of the corresponding candidate cell (or target cell): for example, CU identifier; DU identifier;

[0368] TAG identifier of the candidate cell (target cell), wherein the TAG identifier is used to identify the TAG corresponding to the candidate cell (target cell), which is different from the existing TAG identifier used to identify sPCell and / or SCell, and is used to indicate the TA identifier of the candidate cell which needs to maintain TA;

[0369] TA value (Timing Advance value);

[0370] Time information corresponding to TA.

[0371] Optionally, the time related information corresponding to TA includes any one or more of the following information:

[0372] TAT adjustment value: used to indicate that UE maintains the TA of this candidate cell, when starting TAT, UE needs to adjust the TAT length pre-configured by network side based on the TAT adjustment value;

[0373] TAT length: used to indicate that UE maintains the TA of this candidate cell, when starting TAT, the corresponding length of TAT.

[0374] Time to acquire this TA, the time can be absolute time, this time information is the time information of the serving cell, for example, it can be indicated by UTC time, SFN and subframe time; used to indicate that UE maintains the TA of this candidate cell (or the TA of the TAG corresponding to this candidate cell), when starting TAT, UE needs to start the TAT corresponding to this candidate cell (or the TAG corresponding to this candidate cell) at this time, this time is generally earlier than the current time, so when UE receives the TA, UE considers that the TAT corresponding to this candidate cell (or the TAG corresponding to this candidate cell) has been running for a period of time, the period of time is the difference between the current time and the time to acquire the TA.

[0375] In some embodiments, the candidate cell (target cell) specifically refers to SPCell.

[0376] In some embodiments, the TA related information of SCell contained in the candidate configuration can be selectively contained in the first information sent by the network side.

[0377] In some embodiments, the network side sends the TA related information of one or more candidate cells (target cells) to the UE by one or more of the following methods.

[0378] The network side sends the TA related information of one or more candidate cells (target cells) to the UE through the PHY layer signal.

[0379] The network side sends the TA related information of one or more candidate cells (target cells) to the UE through the MAC layer message; an exemplary MAC CE message can have the following structure:

[0380] (1) RAR: the RAR message is the RAR corresponding to the Preamble received by the candidate cell (target cell) of the UE.

[0381] (2) MAC CE: can contain the TA related information corresponding to one or more candidate cells.

[0382] The network side sends the TA related information of one or more candidate cells (target cells) to the UE through the RRC message.

[0383] In another embodiment, the UE receives TA related information (first information) of one or more candidate cells (or target cells) sent by the serving cell; the UE stores the TA value of the candidate cell (or target cell) and maintains the corresponding TAT based on the content of the above information. When the UE meets the execution condition corresponding to the candidate cell (or the network side triggers the UE to access the candidate cell), if the TA corresponding to the candidate cell is valid, the UE performs RACH-less handover to access the candidate cell and uses the TA as the TA of the accessed cell.

[0384] In another embodiment, the UE maintains multiple TATs for multiple candidate cells (or target cells).

[0385] Optionally, the UE maintains one TAT for each candidate cell TAG (if the candidate cell TAG information is carried).

[0386] Optionally, the UE maintains one TAT for each candidate cell.

[0387] Optionally, the UE maintains one TAT for the candidate cell that partially meets the second condition (different from the handover execution condition).

[0388] The measurement result of the candidate cell is greater than a threshold value.

[0389] If the execution condition corresponding to the candidate cell corresponds to two events, if the candidate cell has met any one of the events.

[0390] In one embodiment, for the TA related information corresponding to the candidate cell contained in the first information, but the candidate cell does not meet the second condition, the UE does not store these TA information.

[0391] In one embodiment, when the UE receives the first information, the UE stores one or more TA related information contained therein and starts the corresponding TAT:

[0392] If the TA related information does not contain the time information corresponding to the TA, the UE starts the corresponding TAT based on the TAT duration (or the default TAT duration) pre-configured by the network side when receiving the first information

[0393] If the TA related information contains the time information corresponding to the TA, the UE starts the TAT based on the time information corresponding to the TA according to the corresponding description in 1 when receiving the first information

[0394] In one embodiment, when the TAT corresponding to the candidate cell (or the TAG corresponding to the candidate cell) times out, the UE deletes the TA related information stored by the UE

[0395] Optionally, the UE can send information to the network (serving cell) to inform the network of the TA timeout and TA invalidation of the candidate cell (or the TAG corresponding to the candidate cell), so that the network can re-initiate the TA acquisition procedure

[0396] In one embodiment, when the candidate cell (target cell) receives the preamble (Msg1) from the UE, the node corresponding to the candidate cell acquires the TA of the UE in the candidate cell and / or the time information (e.g., absolute time information) corresponding to the TA, forwards the TA of the candidate cell and / or the time information (e.g., absolute time information) corresponding to the TA to the node where the serving cell is located, and the serving cell integrates the TA values and time information received from different candidate cells, generates the TA-related information described above sent to the UE by one or more candidate cells (or target cells) based on this, and sends it to the UE.

[0397] Optionally, for the CU and DU separation scenario: the DU where the candidate cell is located acquires the TA of the UE in the candidate cell and / or the time information (e.g., absolute time information) corresponding to the TA, the DU sends the TA and / or the time information corresponding to the TA to the CU of the candidate cell, the CU of the candidate cell forwards it to the CU where the serving cell is located, the CU of the serving cell integrates the TA values and time information received from the CUs of different candidate cells, generates the TA-related information described above sent to the UE by one or more candidate cells (or target cells) based on this, and sends it to the UE. If sent through an RRC message, it can be sent to the UE by the CU; if sent through a MAC or PHY message, the serving CU needs to send the integrated information to the serving DU, which sends it to the UE.

[0398] In one embodiment, when the candidate cell (target cell) receives the preamble (Msg1) from the UE, the node corresponding to the candidate cell acquires the TA of the UE in the candidate cell, forwards the TA of the candidate cell to the node where the serving cell is located, and the serving cell integrates the TA values received from different candidate cells, generates the TA-related information described above sent to the UE by one or more candidate cells (or target cells) based on this, and sends it to the UE. At this time, the time information of the UE starting the TA is generated by the serving cell, and the serving cell needs to send the TA-related information related to the candidate cell to the node corresponding to the candidate cell, and the candidate cell maintains the TA corresponding to the candidate cell based on the TA time information sent by the serving cell, so as to realize the consistency of the TA validity of the network side and the node side

[0399] Optionally, when the TA of the candidate cell corresponding to the candidate node is invalid, that is, the corresponding TAT is expired, the candidate node can send information to the service introduction to inform the UE that the TA of the candidate cell (or the TAG corresponding to the candidate cell) is expired, and the network can reinitiate the TA acquisition process of the candidate cell for the UE.

[0400] The above embodiments are described below by way of example. Referring to FIG. 6, the method includes:

[0401] Step 0: The terminal reports a measurement report.

[0402] The serving base station makes a mobility decision based on the measurement report.

[0408] The purpose of the “candidate configuration” can be at least one of the following:

[0409] Purpose 1: The network device can subsequently control the terminal to change in multiple “candidate cells (or cell groups)” through signaling (such as the “dynamic cell (or cell group) change” in the background technology).

[0410] Purpose 2: The terminal changes the configuration to the candidate cell (or cell group) configuration when it meets the trigger condition configured by the network or agreed by the protocol (such as when the terminal measurement meets the measurement event A3 or A4 or A5 event, the serving cell (or cell group) configuration is changed to the corresponding candidate cell (or cell group). For example, the “mobility process based on condition triggering” in the background technology.

[0411] Among them, the triggering condition includes but is not limited to any one or more of the following events: a triggering event corresponding to a cell-level measurement result based on L3 measurement, and / or a triggering event of a beam-level measurement result based on L1 measurement

[0413] CondEvent A4: Conditional reconfiguration candidate becomes better than absolute threshold where condEventA4can also be used for current PSCell (i.e., in case it is configured as candidate PSCell for CondEvent A4evaluation) for CHO with candidate SCG(s) case;

[0414] CondEvent A5: PCell / PSCell becomes worse than absolute threshold1 AND Conditional reconfiguration candidate becomes better than another absolute threshold2;

[0415] CondEvent D1 : Distance between UE and a reference location referenceLocationl becomes larger than configured threshold distanceThreshFromReference1 and distance between UE and a reference location referenceLocation2 of conditional reconfiguration candidate becomes shorter than configured threshold distanceThreshFromReference2;

[0416] CondEvent D2: Distance between UE and a moving reference location determined based on movingReferenceLocation and its corresponding satellite ephemeris and epoch time broadcast in SIB19 for the serving cell becomes larger than configured threshold distanceThreshFromReference1 and distance between UE and a moving reference location determined based on referenceLocation2 of conditional reconfiguration candidate becomes shorter than configured threshold distanceThreshFromReference2;

[0417] Event LTM2: Beam of serving cell becomes worse than absolute threshold;

[0418] Event LTM3: Beam of candidate cell becomes amount of offset better than beam of serving cell;

[0419] Event LTM4: Beam of candidate cell becomes better than absolute threshold;

[0421] Step 4: The terminal returns a configuration response (RRCReconfigurationComplete) to the serving base station.

[0422] Step 5: The serving base station triggers the terminal to send a random access preamble to perform an early RACH procedure.

[0423] Step 6: The candidate base station 1 and the candidate base station 2 send TA information.

[0424] Step 7: The serving base station sends the TA information to the terminal.

[0425] Step 8: The terminal stores the TA information and maintains a TAT.

[0426] Step 9: The terminal accesses the target cell (serving base station 1).
