Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a resource configuration method, device, terminal and network side equipment. Background Art

[0002] In the related art, for a candidate cell, it may be a candidate cell for multiple terminals that perform continuous layer 1 or layer 2 triggered mobility (L1 / L2Triggered Mobility, LTM) processes. If the candidate cell is configured with a dedicated configured grant (Configured Grant, CG) for each terminal, then these allocated resources will no longer be used by other terminals in the candidate cell, and because it is a continuous LTM, the candidate cell may not always be the target cell of the terminal, so the terminal will not use the CG resources allocated by the candidate cell. Therefore, until the corresponding terminal releases the resources corresponding to the CG configuration, the resources can continue to be allocated. In addition, since in the continuous LTM process, the terminal will not release the candidate cell after the cell switching is successful, and will not release the candidate cell until it receives a clear release signaling, therefore, the candidate cell must reserve dedicated CG resources for the terminal for a long time, and the CG resources configured by the candidate cell cannot be allocated to other terminals and may not be used, which will cause a waste of resources.

As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment 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.

[0057] In order to facilitate understanding of the embodiments of the present application, the following contents are first described.

[0058] In the related art, LTM (L1 / L2 triggered mobility) is introduced. LTM is for cell switching triggered by layer 1 or layer 2. Specifically, the serving base station determines the target cell based on the layer 1 measurement result of the terminal, and uses the LTM command medium access control control element (LTM Command Medium Access Control Control Element, MAC CE) or the LTM cell switch command MAC CE (LTM cell switch command MAC CE) to trigger the terminal 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). In the process of executing LTM, the network side will prepare multiple candidate cells in advance, and send the configuration information of the candidate cells to the terminal through the radio resource control (Radio Resource Control, RRC) signaling, and when the terminal changes the cell, the configuration information of the candidate cells saved by the terminal will not be actively released, but can be used for the subsequent cell switching process, so LTM can also be called continuous LTM.

[0059] In order to reduce the delay of cell change, during the LTM process, the network side NW can trigger the terminal to obtain the timing advance (TA) value of the candidate cell in advance, that is, to obtain the TA of the candidate cell in advance relative to the cell switching. TA is used for the uplink transmission of the terminal to ensure that the uplink data packet of the terminal reaches the base station within the expected time. Specifically, the NW sends a Physical Downlink Control Channel (PDCCH) order to the UE, which carries the identifier of the candidate cell; after receiving the PDCCH order, the UE sends a preamble to the candidate cell indicated by the PDCCH order; then, the candidate cell calculates the TA value of the UE based on the preamble.

[0060] Regarding maintaining the TA value of the candidate cell, in the process of obtaining the TA value of the candidate cell in advance, the terminal may not maintain the TA value of the candidate cell, and the TA value of the candidate cell is maintained by the serving base station. When the serving base station uses LTM commandMAC CE / LTM cell switch command MAC CE to trigger the terminal to perform the LTM process, if the serving base station maintains the TA value of the target cell, the TA value of the target cell will be carried in the MAC CE; after the terminal receives the MAC CE, it can obtain the TA value of the target cell, so there is no need to trigger the random access (Random Access Channel, RACH) process to the target cell, so that a cell switching without random access (RACH-less) can be performed.

[0061] In order to solve the problem of resource waste caused by the resource configuration method of the existing LTM process, the embodiment of the present application proposes a configuration method of the CG of the LTM based on RACH-less. Specifically, in the process of the terminal executing the TA of the candidate cell in advance or before / after the execution, the candidate cell (source cell) configures the CG of the LTM of the terminal, and releases the configured resources when the terminal completes the handover. The specific contents include:

[0062] 1. The candidate cell allocates configured UL grant resources to the terminal or activates CG resources allocated to the terminal during the process of the terminal executing the advance acquisition of the TA of the candidate cell;

[0063] 2. In the process of obtaining the TA of the candidate cell in advance, if the network does not send a random access response RAR, the candidate cell sends the configured UL grant resources or the activation command of the pre-configured CG to the source cell, and the source cell sends it to the terminal through an RRC message or MAC CE or downlink control information (Downlink Control Information, DCI);

[0064] 3. In the case where the network sends a random access response RAR during the process of acquiring the TA of the candidate cell in advance, the candidate cell can send the configured UL grant resources or the activation command of the pre-configured CG to the terminal through the RAR;

[0065] 4. After determining that the terminal handover is successful or the candidate cell sends a handover command, the candidate cell releases or deactivates the configured UL grant resources;

[0066] 5. After determining that the terminal handover is successful or the candidate cell sends a handover command, the target cell notifies other candidate cells to release or deactivate the configured UL grant resources configured for the terminal, or the source cell notifies other candidate cells to release or deactivate the configured UL grant resources configured for the terminal.

[0067] The resource configuration method, apparatus, terminal and network side equipment provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

[0068] See also Figure 2 , Figure 2 is a flow chart of a resource configuration method provided in an embodiment of the present application, the method is executed by a terminal, such as Figure 2 As shown, the method comprises the following steps:

[0069] Step 21: The terminal receives the first uplink authorization configuration information of the candidate cell used in the LTM process;

[0070] Step 22: The terminal sends an uplink message to the target cell during the cell switching process according to the first uplink authorization configuration information;

[0071] Step 23: After the handover is successful, the terminal releases or deactivates the first uplink authorization configuration information of the candidate cell.

[0072] Here, the first uplink authorization configuration information can be configured and sent before executing the process of obtaining the TA of the candidate cell in advance, or configured and sent during or after the execution of obtaining the TA of the candidate cell in advance, so as to avoid premature allocation or activation of the resources of the candidate cell in the LTM process compared to the related art of sending the uplink authorization configuration information in the LTM accurate stage. The first uplink authorization configuration information can be used to configure CG resources for the terminal, such as CG uplink resources.

[0073] Optionally, the sending of an uplink message to the target cell during the cell switching process may be sending the first uplink message to the target cell during the cell switching process.

[0074] Optionally, the above-mentioned releasing or deactivating the first uplink authorization configuration information of the candidate cell includes: determining the CG resources associated with the first uplink authorization configuration information of the candidate cell, and releasing the CG resources associated with the first uplink authorization configuration information of the candidate cell.

[0075] Therefore, with the help of the solution in this application, the resources configured by the candidate cell during the LTM process can be released or deactivated in a timely manner for use by other terminals, thereby effectively solving the problem of resource waste, avoiding resource waste, and improving resource utilization.

[0076] In the embodiment of the present application, the terminal may receive the first uplink authorization configuration information in a variety of ways. The above step 21 may include at least one of the following:

[0077] (1) After executing the process of obtaining the TA of the candidate cell in advance, the terminal receives a first message sent by the source cell, where the first message includes the first uplink authorization configuration information; for example, the first message may be an RRCReconfiguration message or other RRC messages;

[0078] (2) The terminal receives a first cell handover command sent by a source cell, where the first cell handover command includes the first uplink authorization configuration information, and the candidate cell is a target cell;

[0079] (3) When executing the process of acquiring the TA of the candidate cell in advance, the terminal receives a random access response message sent by the source cell or the candidate cell, where the random access response message includes the first uplink authorization configuration information.

[0080] In this way, by sending the first uplink authorization configuration information by means of the above (1) to (3), compared with sending the uplink authorization configuration information in the LTM accurate stage in the related art, it is possible to avoid premature allocation or activation of candidate cell resources in the LTM process.

[0167] Example 1

[0168] In this embodiment 1, there is no random access response RAR in the process of UE acquiring the TA of the candidate cell in advance. In the process of acquiring the TA of the candidate cell in advance (such as early TA acquisition), or after the process of acquiring the TA of the candidate cell in advance is completed, the candidate cell allocates CG resources and sends the CG resources to the source cell, and the source cell uses RRC message to send it to the UE. The specific UE behavior includes:

[0169] Step 1: The UE receives an RRC reconfiguration message, which carries (i.e. includes) the configuration information of the candidate cells in the LTM process; if the configuration information includes CG configuration information, the CG configuration information carries the fourth uplink authorization configuration information, and the fourth uplink authorization configuration information is specifically as described in the above embodiment and will not be repeated here.

[0170] Step 2: The UE receives a PDCCH order sent by the source base station (i.e., the base station in the source cell). The PDCCH order is used to trigger the UE to execute a process of acquiring the TA in advance to the candidate cell (e.g., candidate cell #1, i.e., C-cell #1). The PDCCH order may carry the following information:

[0171] -Identification of candidate cells;

[0172] -Preamble retransmission or initial transmission indication information;

[0176] -Physical Random Access Channel (PRACH) mask index (Maskindex).

[0177] Step 3: The UE sends a preamble to the candidate cell according to the PDCCH order. Afterwards, the candidate cell can calculate the TA value of the UE according to the preamble and send it to the source cell.

[0178] Step 4: The UE receives a first message sent by the source base station, which carries first uplink authorization configuration information of one or more candidate cells. For example, the first message may be an RRCReconfiguration message or other RRC messages.

[0179] Optionally, the implementation method of the first uplink authorization configuration information may be specifically as implementation method 1, implementation method 2-1 or implementation method 2-2 in the above embodiments, which will not be described again here to avoid repetition.

[0180] Optionally, the UE stores the first uplink authorization configuration information.

[0181] Optionally, the first uplink authorization configuration information also includes a public C-RNTI or a temporary C-RNTI.

[0183] Step 5: The UE receives the LTM cell switching command sent by the source base station, such as sent via MAC CE, which carries the identifier of the target cell and the TA value of the target cell, for example, carries the configuration identifier of C-cell#1.

[0184] Step 6: The UE performs RACH-less based LTM cell switching, such as applying the RRC configuration information of the target cell C-cell#1, wherein the RRC configuration information includes the candidate configuration information associated with the target cell and the associated first uplink authorization configuration information, and sends a first uplink message to the target cell C-cell#1, wherein the first uplink message is, for example, an RRC reconfiguration complete (RRCReconfigurationComplete) message or other uplink message.

[0185] Optionally, the UE determines uplink resources, such as physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) resources, based on the fourth uplink authorization configuration information and the second uplink authorization configuration information associated with the target cell or based on the first uplink authorization configuration information associated with the target cell (corresponding to the case where the fourth uplink authorization configuration information does not exist), and sends an uplink message on the uplink resources.

[0186] Optionally, determining the time domain resource of the PUSCH resource includes: using the following formula to determine the system frame number (System Frame Number, SFN), time slot slot and symbol symbol:

[0187] [(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)+(slot number in the frame×numberOfSymbolsPerSlot)+symbol number in the slot]=

[0188] (timeDomainOffset×numberOfSymbolsPerSlot+S+N×periodicity)modulo(1024×numberOfSlotsPerFrame×numberOfSymbolsPerSlot), N>=0

[0189] In the above formula, SFN, slot number in the frame, and symbol number in the slot are the time domain positions of the PUSCH resources; other parameters are:

[0190] numberOfSlotsPerFrame: the number of time slots contained in one frame of the target cell;

[0191] numberOfSymbolsPerSlot: the number of symbols contained in one time slot in the target cell;

[0192] timeDomainOffset: the time domain offset carried in the fourth uplink authorization configuration information or the first uplink authorization configuration information;

[0193] S: the S value carried in the fourth uplink authorization configuration information or the first uplink authorization configuration information;

[0194] Periodicity: the period of the configured UL grant carried in the fourth uplink grant configuration information or the first uplink grant configuration information;

[0195] N is a positive integer.

[0196] Step 7: After the UE sends the first uplink message, such as the RRCReconfigurationComplete message, and confirms that the network side device of the target cell (such as the target base station) has successfully received the first uplink message, such as the RRCReconfigurationComplete message, it considers that the LTM is executed successfully and releases the first uplink authorization configuration information of all candidate cells.

[0197] Optionally, if the UE tells the target cell the UE identifier, such as C-RNTI, during the early TA acquisition process, the UE uses the C-RNTI to scramble the first uplink message when sending the uplink message.

[0198] Optionally, if the UE does not tell the target cell the UE identifier during the early TA acquisition process, but the target cell allocates a common C-RNTI or a temporary C-RNTI to the UE when allocating CG resources to the UE, such as carrying it in the first uplink authorization configuration information sent, then when the UE sends the first uplink message, it can use the common C-RNTI or temporary C-RNTI to scramble the uplink message and tell the target cell the UE identifier, such as C-RNTI, in the uplink message.

[0199] Example 2

[0200] In this embodiment 2, there is no random access response RAR in the process of UE acquiring the TA of the candidate cell in advance. During the early TA acquisition process, or after the early TA acquisition process is completed, the candidate cell allocates CG resources to the UE that sends the preamble, and optionally sends the configuration information of the CG resources along with the TA value to the source cell; the source cell matches the UE and sends the configuration information of the CG resources to the UE during the cell handover, along with the TA value. The specific UE behaviors include:

[0201] Step 1: The UE receives an RRCReconfiguration message, which carries the configuration information of the candidate cells in the LTM process; if the configuration information includes CG configuration information, the CG configuration information carries the fourth uplink authorization configuration information, and the fourth uplink authorization configuration information is specifically as described in the above embodiment and will not be repeated here.

[0202] Step 2: The UE receives a PDCCH order sent by a source base station (i.e., a base station in a source cell), wherein the PDCCH order is used to trigger the UE to execute a process of acquiring a TA in advance to a candidate cell (e.g., candidate cell #1, i.e., C-cell #1). The information carried in the PDCCH order may be as described in the above-mentioned embodiment 1.

[0203] Step 3: The UE sends a preamble to the candidate cell according to the PDCCH order. Afterwards, the candidate cell can calculate the TA value of the UE according to the preamble and send it to the source cell.

[0204] Step 4: The UE receives the LTM cell switching command (such as cell switch command, corresponding to the first cell switching command mentioned above) sent by the source base station, such as sent via MAC CE, which carries the identifier of the target cell, the TA value of the target cell and the first uplink authorization configuration information of the target cell.

[0205] Optionally, the implementation method of the first uplink authorization configuration information may be specifically as implementation method 1, implementation method 3-1 or implementation method 3-2 in the above embodiments, which will not be described again here to avoid repetition.

[0206] Step 5: The UE performs RACH-less based LTM cell switching, such as applying the RRC configuration information of the target cell C-cell#1, wherein the RRC configuration information includes the candidate configuration information associated with the target cell and the associated first uplink authorization configuration information, and sends a first uplink message to the target cell C-cell#1, wherein the first uplink message is, for example, an RRC reconfiguration complete (RRCReconfigurationComplete) message or other uplink messages.

[0207] Step 6: After the UE sends the first uplink message, such as the RRCReconfigurationComplete message, and confirms that the network side device of the target cell (such as the target base station) has successfully received the first uplink message, such as the RRCReconfigurationComplete message, it considers that the LTM is executed successfully and releases the first uplink authorization configuration information of the target cell.

[0208] Optionally, if the UE tells the target cell the UE identifier, such as C-RNTI, during the early TA acquisition process, the UE uses the C-RNTI to scramble the first uplink message when sending the uplink message.

[0209] Optionally, if the UE does not tell the target cell the UE identifier during the early TA acquisition process, but the target cell allocates a common C-RNTI or a temporary C-RNTI to the UE when allocating CG resources to the UE, such as carrying it in the first uplink authorization configuration information sent, then when the UE sends the first uplink message, it can use the common C-RNTI or temporary C-RNTI to scramble the uplink message and tell the target cell the UE identifier, such as C-RNTI, in the uplink message.

[0210] Example 3

[0211] In this embodiment 3, there is no random access response RAR in the process of UE acquiring the TA of the candidate cell in advance. CG resources are configured during the LTM preparation process, but the candidate cell may not activate the CG resources for the UE; during or after the early TA acquisition process, the candidate cell activates the previously configured unactivated CG resources, and the source cell sends an activation command to the UE before switching. The specific UE behaviors include:

[0212] Step 1: UE receives an RRCReconfiguration message, which carries the configuration information of the candidate cell in the LTM process; if the configuration information includes CG configuration information, the CG configuration information carries the first uplink authorization configuration information; the first uplink authorization configuration information is specifically the first uplink authorization configuration information sent before executing the TA process of early acquiring the candidate cell in the above embodiment, and the content carried therein can be referred to the above embodiment. To avoid repetition, it will not be repeated here.

[0213] Step 2: The UE receives a PDCCH order sent by a source base station (i.e., a base station in a source cell). The PDCCH order is used to trigger the UE to execute a process of acquiring a TA in advance to a candidate cell (e.g., candidate cell #1, i.e., C-cell #1). The information carried in the PDCCH order is as described in the above embodiment 1 and will not be repeated here.

[0214] Step 3: The UE sends a preamble to the candidate cell according to the PDCCH order. Afterwards, the candidate cell can calculate the TA value of the UE according to the preamble and send it to the source cell.

[0215] Step 4: The UE receives first activation information of the candidate cell sent by the source base station. The first activation information may be specifically as described in the above embodiment, which will not be repeated here.

[0216] Step 5: The UE receives the LTM cell switching command sent by the source base station, such as sent via MAC CE, which carries the identifier of the target cell and the TA value of the target cell, for example, carries the configuration identifier of C-cell#1.

[0217] Step 6: The UE performs RACH-less based LTM cell switching, such as applying the RRC configuration information of the target cell C-cell#1, wherein the RRC configuration information includes the candidate configuration information associated with the target cell and the associated first uplink authorization configuration information, and sends a first uplink message to the target cell C-cell#1, wherein the first uplink message is, for example, an RRC reconfiguration complete (RRCReconfigurationComplete) message or other uplink message.

[0218] Step 7: After the UE sends the first uplink message, such as the RRCReconfigurationComplete message, and confirms that the network side device of the target cell (such as the target base station) has successfully received the first uplink message, such as the RRCReconfigurationComplete message, it considers that after the LTM is executed successfully, it considers that the CG resources related to the first UL data transmission of all candidate cells are deactivated, that is, the resources will no longer be used until the relevant activation command is received again.

[0219] In this solution, the UE tells the target cell the UE identifier, such as C-RNTI, during the early TA acquisition process. When the UE sends the first uplink message, it uses the C-RNTI to scramble the uplink message.

[0220] Example 4

[0221] In this embodiment 4, there is no random access response RAR in the process of UE acquiring the TA of the candidate cell in advance. CG resources are configured in the LTM preparation process, but the candidate cell may not activate the CG resources for the UE; in the early TA acquisition process or after the early TA acquisition process, the candidate cell activates the previously configured CG resources, and the source cell uses the handover command to send the activation command to the UE during the handover. The specific UE behavior includes:

[0222] Step 1: UE receives an RRCReconfiguration message, which carries the configuration information of the candidate cell in the LTM process; if the configuration information includes CG configuration information, the CG configuration information carries the first uplink authorization configuration information; the first uplink authorization configuration information is specifically the first uplink authorization configuration information sent before executing the TA process of early acquiring the candidate cell in the above embodiment, and the content carried therein can be referred to the above embodiment. To avoid repetition, it will not be repeated here.

[0223] Step 2: The UE receives a PDCCH order sent by a source base station (i.e., a base station in a source cell). The PDCCH order is used to trigger the UE to execute a process of acquiring a TA in advance to a candidate cell (e.g., candidate cell #1, i.e., C-cell #1). The information carried in the PDCCH order is as described in the above embodiment 1 and will not be repeated here.

[0224] Step 3: The UE sends a preamble to the candidate cell according to the PDCCH order. Afterwards, the candidate cell can calculate the TA value of the UE according to the preamble and send it to the source cell.

[0226] Step 5: The UE performs RACH-less based LTM cell switching, such as applying the RRC configuration information of the target cell C-cell#1, wherein the RRC configuration information includes the candidate configuration information associated with the target cell and the associated first uplink authorization configuration information, and sends a first uplink message to the target cell C-cell#1, wherein the first uplink message is, for example, an RRC reconfiguration complete (RRCReconfigurationComplete) message or other uplink messages.

[0227] Step 6: After the UE sends the first uplink message, such as the RRCReconfigurationComplete message, and confirms that the network side device of the target cell (such as the target base station) has successfully received the first uplink message, such as the RRCReconfigurationComplete message, it considers that after the LTM is executed successfully, it considers that the CG resources related to the first UL data transmission associated with the target cell are deactivated, that is, the resources will no longer be used until the relevant activation command is received again.

[0228] In this solution, the UE tells the target cell the UE identifier, such as C-RNTI, during the early TA acquisition process. When the UE sends the first uplink message, it uses the C-RNTI to scramble the uplink message.

[0229] Example 5

[0230] In this embodiment 5, there is a random access response RAR in the process of UE acquiring the TA of the candidate cell in advance. In early TA acquisition, the candidate cell allocates CG resources and generates a RAR message, and sends the RAR message to the source cell, and the source cell uses the RAR in early TA acquisition to send the CG resources to the UE; or the candidate cell allocates CG resources and generates a RAR message, and directly sends the CG resources to the UE through the RAR message in early TA acquisition. Specific UE behaviors include:

[0231] Step 1: The UE receives an RRCReconfiguration message, which carries the configuration information of the candidate cells in the LTM process; if the configuration information includes CG configuration information, the CG configuration information carries the fourth uplink authorization configuration information, and the fourth uplink authorization configuration information is specifically as described in the above embodiment and will not be repeated here.

[0232] Step 2: The UE receives a PDCCH order sent by a source base station (i.e., a base station in a source cell), wherein the PDCCH order is used to trigger the UE to execute a process of acquiring a TA in advance to a candidate cell (e.g., candidate cell #1, i.e., C-cell #1). The information carried in the PDCCH order may be as described in the above-mentioned embodiment 1.

[0233] Step 3: The UE sends a preamble to the candidate cell according to the PDCCH order. Afterwards, the candidate cell can calculate the TA value of the UE according to the preamble.

[0234] Step 4: The UE receives a RAR message (such as msg2 message), which is sent from the source cell or the candidate cell; the RAR message sent by the source cell may be a MAC CE scrambled by C-RNTI or RA-RNTI, or a MAC PDU scrambled by C-RNTI or RA-RNTI. The RAR message carries one or more of the candidate cell identifier, the candidate cell TA value, and the first uplink authorization configuration information.

[0235] Optionally, the implementation method of the first uplink authorization configuration information may be specifically as implementation method 1, implementation method 3-1 or implementation method 3-2 in the above embodiments, which will not be described again here to avoid repetition.

[0236] Optionally, the UE stores the first uplink authorization configuration information.

[0237] Step 5: The UE receives the LTM cell switching command sent by the source base station, such as sent via MAC CE, which carries the identifier of the target cell and the TA value of the target cell, for example, carries the configuration identifier of C-cell#1.

[0238] Step 6: The UE performs RACH-less based LTM cell switching, such as applying the RRC configuration information of the target cell C-cell#1, wherein the RRC configuration information includes the candidate configuration information associated with the target cell and the associated first uplink authorization configuration information, and sends a first uplink message to the target cell C-cell#1, wherein the first uplink message is, for example, an RRC reconfiguration complete (RRCReconfigurationComplete) message or other uplink message.

[0239] Step 7: After the UE sends the first uplink message, such as the RRCReconfigurationComplete message, and confirms that the network side device of the target cell (such as the target base station) has successfully received the first uplink message, such as the RRCReconfigurationComplete message, it considers that the LTM is executed successfully and releases the first uplink authorization configuration information of all candidate cells.

[0240] Optionally, if the UE tells the target cell the UE identifier, such as C-RNTI, during the early TA acquisition process, the UE uses the C-RNTI to scramble the first uplink message when sending the uplink message.

[0241] Optionally, if the UE does not tell the target cell the UE identifier during the early TA acquisition process, but the target cell allocates a common C-RNTI or a temporary C-RNTI to the UE when allocating CG resources to the UE, such as carrying it in the first uplink authorization configuration information sent, then when the UE sends the first uplink message, it can use the common C-RNTI or temporary C-RNTI to scramble the uplink message and tell the target cell the UE identifier, such as C-RNTI, in the uplink message.

[0242] Example 6

[0243] In this embodiment 6, there is a random access response RAR in the process of UE acquiring the TA of the candidate cell in advance. CG resources are configured in the LTM preparation process, but the candidate cell does not activate the CG resources for the UE; in the early TA acquisition process, the candidate cell activates the previously configured CG resources and generates a RAR message, and sends the RAR message to the source cell, and the RAR of the source cell in the early TA acquisition sends the activation command to the UE; or the candidate cell allocates CG resources and generates a RAR message, and directly sends the CG resources to the UE through the RAR message in the early TA acquisition. Specific UE behaviors include:

[0244] Step 1: UE receives an RRCReconfiguration message, which carries the configuration information of the candidate cell in the LTM process; if the configuration information includes CG configuration information, the CG configuration information carries the first uplink authorization configuration information; the first uplink authorization configuration information is specifically the first uplink authorization configuration information sent before executing the TA process of early acquiring the candidate cell in the above embodiment, and the content carried therein can be referred to the above embodiment. To avoid repetition, it will not be repeated here.

[0245] Step 2: The UE receives a PDCCH order sent by a source base station (i.e., a base station in a source cell). The PDCCH order is used to trigger the UE to execute a process of acquiring a TA in advance to a candidate cell (e.g., candidate cell #1, i.e., C-cell #1). The information carried in the PDCCH order is as described in the above embodiment 1 and will not be repeated here.

[0246] Step 3: The UE sends a preamble to the candidate cell according to the PDCCH order. Afterwards, the candidate cell can calculate the TA value of the UE according to the preamble.

[0247] Step 4: The UE receives a RAR message (such as msg2 message), which is sent from the source cell or the candidate cell; the RAR message sent by the source cell may be a MAC CE scrambled by C-RNTI or RA-RNTI, or a MAC PDU scrambled by C-RNTI or RA-RNTI. The RAR message carries the identifier of the candidate cell, the TA value of the candidate cell, and activation indication information (i.e., the sixth indication information mentioned above).

[0248] Step 5: The UE receives the LTM cell switching command sent by the source base station, such as sent via MAC CE, which carries the identifier of the target cell and the TA value of the target cell, for example, carries the configuration identifier of C-cell#1.

[0249] Step 6: The UE performs RACH-less based LTM cell switching, for example, using the RRC configuration information of the target cell C-cell#1, wherein the RRC configuration information includes the candidate configuration information associated with the target cell and the associated first uplink authorization configuration information, and sends a first uplink message to the target cell C-cell#1, wherein the first uplink message is, for example, an RRC reconfiguration complete (RRCReconfigurationComplete) message or other uplink message.

[0250] Step 7: After the UE sends the first uplink message, such as the RRCReconfigurationComplete message, and confirms that the network side device of the target cell (such as the target base station) has successfully received the first uplink message, such as the RRCReconfigurationComplete message, it considers that after the LTM is executed successfully, it considers that the CG resources related to the first UL data transmission of all candidate cells are deactivated, that is, the resources will no longer be used until the relevant activation command is received again.

[0251] In this solution, the UE tells the target cell the UE identifier, such as C-RNTI, during the early TA acquisition process. When the UE sends the first uplink message, it uses the C-RNTI to scramble the uplink message.

[0252] See also Figure 3 , Figure 3 1 is a flow chart of a resource configuration method provided by an embodiment of the present application, the method is executed by a first network side device, and the first network side device is a network side device of a candidate cell related to LTM. Figure 3 As shown, the method comprises the following steps:

[0253] Step 31: The first network side device sends fifth uplink authorization configuration information to the second network side device.

[0254] In this embodiment, the fifth uplink authorization configuration information may be configured and sent before executing the process of obtaining the TA of the candidate cell in advance, or the fifth uplink authorization configuration information may be configured and sent during or after the execution of obtaining the TA of the candidate cell in advance. The fifth uplink authorization configuration information is configured by the first network side device for the terminal, and the second network side device is a network side device of the source cell.

[0255] Step 32: The first network side device receives seventh indication information, where the seventh indication information is used to instruct the first network side device to release or deactivate the CG resources associated with the RACH-less-based LTM configured by it;

[0256] Step 33: The first network side device releases or deactivates the CG resources according to the seventh indication information.

[0257] Optionally, the seventh indication information includes an identifier of the first terminal, and the seventh indication information is used to instruct the first network side device to release or deactivate CG resources associated with the RACH-less based LTM configured for the first terminal; or, the seventh indication information includes CG related information, such as a CG identifier, and the seventh indication information is used to instruct the first network side device to release or deactivate CG resources associated with the CG related information.

That is, the candidate cell may receive the seventh indication information sent by the source cell or the target cell.

[0259] Therefore, with the help of the solution in this application, it is possible to avoid premature allocation or activation of candidate cell resources during the LTM process, and timely release or deactivate the resources configured for the candidate cell during the LTM process for use by other terminals, thereby effectively solving the problem of resource waste, avoiding resource waste, and improving resource utilization.

[0361] The present application is described below in conjunction with specific embodiments.

[0362] Example 7

[0363] In this embodiment 7, for the case where there is no random access response RAR during the process of the UE obtaining the TA of the candidate cell in advance, it corresponds to the above-mentioned embodiments 1, 2, 3 and 4. The network side behavior of the network side device of the candidate cell includes:

[0364] Step 1: The network side device of the candidate cell sends a second message to the network side device of the source cell, which carries the candidate cell configuration information, wherein the candidate cell configuration information includes but is not limited to the fourth uplink authorization configuration information (or the fifth uplink authorization configuration information, corresponding to the case of using in combination with the activation information) and the RACH configuration information for obtaining the TA in advance. Optionally, the fourth uplink authorization configuration information may be as described in the above embodiment, which will not be repeated here.

[0365] Optionally, the second message may be a switching request confirmation message in the case of inter-CU switching; or, the second message may be a UE context creation (UE Context setup) message, or a UE context modification (UE Context Modification) message, etc. in the case of intra-CU switching.

[0366] Step 2: If the RACH resources acquired in advance by the TA are shared, the network side device of the candidate cell receives contention free random access (CFRA) resource related information from the network side device of the source cell, and optionally receives the UE identifier.

[0367] The effect achieved by this step 2 is: since the RACH resources for obtaining the TA of the candidate cell in advance are shared, when the UE executes the process of obtaining the TA of the candidate cell in advance, the candidate cell cannot determine the UE identity through the PRACH resources and preamble used by the UE; and based on this step 2, before the source cell triggers the UE to execute the process of obtaining the TA of the candidate cell in advance, the UE identity and the RACH resources used by the candidate cell are notified, so that the candidate cell can determine the UE identity, so that the corresponding CG resources can be allocated to the UE.

[0368] Step 3: The network side device of the candidate cell receives the preamble code preamble on the configured PRACH resource for early acquisition of TA, and calculates the TA value according to the preamble; and if the RACH resource for early acquisition of TA is not shared, the candidate cell determines the UE identity according to the RACH resource.

[0369] Optionally, for the situations in the above-mentioned embodiments 1 and 2, the network side device of the candidate cell configures first uplink authorization configuration information for the terminal, and the content included in the first uplink authorization configuration information is specifically as described in the above-mentioned embodiments.

[0371] Optionally, if the candidate cell cannot obtain the UE identifier in the above step 2, a public C-RNTI or a temporary C-RNTI can be carried in the fifth uplink authorization configuration information sent.

[0404] d) The source CU notifies the target CU of the CU of the candidate cell configured with the configured UL grant resources. After determining that the UE successfully accesses the target cell, the target CU notifies the CU of the candidate cell configured with the configured UL grant resources to release or deactivate the configured UL grant resources.
