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.

[0040] The resource scheduling method, apparatus, terminal, network-side equipment, and medium provided in the embodiments of the present application are described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0041] Currently, the NR access network can split the gNB into a centralized unit (gNB-CU) and a distributed unit (gNB-DU), connected via the F1 interface. Figure 2 shows the CU-DU architecture. As shown in Figure 2, a gNB contains only one CU and two DUs (in actual implementation, it can contain one or more DUs). A DU contains at least one cell. The CU includes the Packet Data Convergence Protocol (PDCP) and the protocol stack above it, while the DU includes the protocol stack below PDCP, such as the Radio Link Control (RLC), Multiple Access Control (MAC), and Physical (PHY) protocols. On the control plane, the CU includes Radio Resource Control (RRC) and the control-plane PDCP (PDCP-C). On the user plane, the CU includes the Service Data Adaptation Protocol (SDAP) and the user-plane PDCP (PDCP-U).

[0042] In NR, in response to the needs of low-latency services or periodic services, NR supports uplink semi-static CG transmission mode to reduce the signaling interaction process and ensure low latency requirements. The resources for CG transmission can be semi-statically configured through RRC signaling. When service data arrives, the terminal can send data on the uplink channel of CG. NR supports type 1 and type 2 types of configuration authorization physical uplink shared channels (CG Physical Uplink Shared Channel, CG PUSCH). For type 1 CG PUSCH, after the RRC parameters are configured, the terminal can transmit data on the CG PUSCH. For type 2 CG PUSCH, the terminal can transmit data on the CG PUSCH only after the RRC parameters are configured and the DCI activates the CG PUSCH.

[0043] To reduce the LTM handover interruption time caused by uplink synchronization (i.e., the random access process), 3GPP has discussed and adopted handover schemes based on Early Random Access Channel (Early-rach) or Random Access Channel-less (RACH-less). Early-rach means that the candidate cell allocates contention-free random access (CFRA) resources to the terminal. Before initiating handover, the terminal performs a RACH on the candidate cell to obtain the candidate cell's Time Advanced (TA) value. RACH-less means that the terminal does not perform a RACH during the handover process. The candidate cell's TA value is obtained through the Early-rach process, or the candidate cell's TA value is the same as the source cell's, so no TA is required. During the RACH-less process, the target cell needs to allocate uplink resources to the terminal through dynamic scheduling or CG scheduling, so that the terminal can transmit a handover completion indication on the corresponding resources.

[0044] As can be seen from the above, for Random Access Channel less (RACH-less) handover, the supported solutions in L1 / L2 triggered mobility (LTM) include: the target cell in at least one candidate cell provides the terminal with periodic uplink configuration authorization (CG) resources in advance. After receiving the handover command sent by the current resident cell, the terminal uses the CG resources allocated by the target cell for uplink transmission to complete the RACH-less handover. However, when multiple terminals sharing the same CG resources initiate RACH-less handover at the same time, due to the conflict of CG resources used by the multiple terminals, the RACH-less handover delay of some terminals will be too long, or even the handover will fail.

[0045] In order to solve the above problems, in the resource scheduling method provided in the embodiment of the present application, the first terminal can receive a cell switching command sent by the first node device, the cell switching command is used to instruct the first terminal to switch to the first cell, and the cell switching command includes a first indication information, and the first indication information is used to indicate whether the CG resources corresponding to the first terminal are available; and based on the first indication information, access the first cell. The method of indicating to the first terminal whether the CG resources allocated to the first terminal are available through the first indication information can enable the first terminal to determine whether to use the CG resources for uplink transmission according to the indication of the first indication information. Therefore, when multiple terminals sharing the same CG resources initiate RACH-less switching at the same time, it can avoid excessive RACH-less switching delays of some terminals or even switching failures caused by conflicts in the CG resources used by the multiple terminals.

[0046] The embodiment of the present application provides a resource scheduling method, and Figure 3 shows a flow chart of the resource scheduling method provided by the embodiment of the present application.

[0072] Optionally, in an embodiment of the present application, if the identifiers of the CG resources or the indexes of the CG resources associated with any two terminals corresponding to the first node device are different, the first node device can determine that the terminals corresponding to the first node device are not allocated the same CG resources.

[0073] In an embodiment of the present application, since the identification information of the above-mentioned CG resources or the index information of the above-mentioned CG resources can be used for: the above-mentioned first node device to determine whether the terminal corresponding to the first node device is allocated the same CG resources, the first node device can quickly determine whether the terminal corresponding to the first node device is allocated the same CG resources through the identification information of the CG resources or the index information of the CG resources.

[0077] Optionally, in an embodiment of the present application, when the at least one CG resource configuration information includes the at least one terminal identification list information, the first node device can determine that the second node device allocates the same CG resource to the terminal corresponding to the at least one terminal identification list information.

[0078] In an embodiment of the present application, since the above-mentioned first terminal identification list information can be used to indicate that all terminals corresponding to the first terminal identification list information are allocated the same CG resources, it is convenient for the above-mentioned first node device to determine whether the terminal corresponding to the first node device is allocated the same CG resources.

[0079] Step 302: The first node device sends first indication information to the first terminal.

[0080] Among them, the above-mentioned first indication information is used to indicate whether the CG resources corresponding to the above-mentioned first terminal of the above-mentioned second node device are available.

[0104] The TA-related information of the first cell carried in the cell handover command may, for example, be information indicating that the TA value of the first terminal in the first cell is the same as a TAG (i.e., label) in the currently accessed cell;

[0105] Network configuration, for example, the first terminal may obtain the TA value of the first cell through a UE based TA measurement process.

[0106] Optionally, in an embodiment of the present application, if the first terminal fails to obtain the TA value of the first cell, it can be considered that the cell switching command does not carry the TA value of the first cell and the TA-related information of the first cell, and the first terminal cannot obtain the TA value of the first cell through the UE based TA measurement process.

[0107] In an embodiment of the present application, since the above-mentioned first terminal can access the above-mentioned first cell based on the above-mentioned first indication information and whether the TA value of the above-mentioned first cell is obtained, it is possible to avoid excessive RACH-less switching delay or even switching failure of some terminals caused by the conflict of CG resources used by multiple terminals.

[0108] Optionally, in the embodiment of the present application, the above step 402a can be specifically implemented through the following step 402a1, step 402a2 or step 402a3.

[0109] Step 402a1: When the first indication information indicates that CG resources are available and the TA value of the first cell has been obtained, the first terminal uses the CG resources to transmit uplink data and performs a RACH-less switching process based on the configuration authorization to access the first cell.

[0110] Step 402a2: When the first indication information indicates that the CG resource is unavailable and the TA value of the first cell is not obtained, the first terminal performs a RACH switching process to access the first cell.

[0111] Step 402a3: When the first indication information indicates that CG resources are unavailable and the TA value of the first cell has been obtained, the first terminal monitors the uplink dynamic scheduling of the first cell and performs a RACH-less switching process based on dynamic scheduling to access the first cell.

[0112] For the detailed description of the RACH-less switching process based on configuration authorization, the RACH switching process, and the RACH-less switching process based on dynamic scheduling, reference may be made to the relevant description in the related art. To avoid repetition, they are not described here.

[0113] In an embodiment of the present application, since the above-mentioned first terminal can execute different switching processes to access the above-mentioned first cell based on whether the CG resources indicated by the above-mentioned first indication information are available and whether the TA value of the above-mentioned first cell is obtained, it can further avoid the RACH-less switching delay of some terminals being too long or even the switching failure caused by the conflict of CG resources used by multiple terminals.

[0114] For other descriptions of the resource scheduling method provided in the embodiment of the present application, please refer to the relevant descriptions in the above-mentioned first node device side method embodiment. In order to avoid repetition, they will not be repeated here.

[0115] In the resource scheduling method provided in an embodiment of the present application, by indicating to the first terminal via first indication information whether the CG resource allocated to the first terminal is available, the first terminal can determine whether to use the CG resource for uplink transmission based on the indication of the first indication information. Thus, when multiple terminals sharing the same CG resource simultaneously initiate RACH-less handover, excessive RACH-less handover delays or even handover failures for some terminals caused by conflicts in the CG resources used by the multiple terminals can be avoided.

[0116] The present invention provides another resource scheduling method, and Figure 5 shows a flow chart of the resource scheduling method provided by the present invention. As shown in Figure 5, the resource scheduling method provided by the present invention may include the following steps 501 to 503.

[0117] Step 501: A second node device receives a first notification message sent by a first node device.

[0118] The first notification message is used to instruct: the second terminal corresponding to the first node device initiates handover to the first cell corresponding to the second node device.

[0119] Optionally, in an embodiment of the present application, the first notification message may include: the terminal identifier of the second terminal, the cell identifier of the first cell, and a transmission configuration indicator (TCI) status identifier corresponding to the second terminal.

[0120] Optionally, in an embodiment of the present application, the TCI status identifier may be carried in a cell switching command sent by the first node device to the second terminal.

[0121] In an embodiment of the present application, since the above-mentioned first notification message can include the terminal identifier of the above-mentioned second terminal, the cell identifier of the above-mentioned first cell, and the above-mentioned TCI status identifier, it is convenient for the second node device to obtain relevant information of the second terminal that needs to be switched to the first cell.

[0122] For example, assuming that the above-mentioned first node device is the first DU and the above-mentioned second node device is the second DU, then the first DU can first send the above-mentioned first notification message to the first CU to which the first DU belongs, and then the first CU sends the first notification message to the second CU to which the second DU belongs, and finally the second CU sends the first notification message to the second DU.

[0123] It should be noted that, if the first DU and the second DU belong to the same CU, the first CU and the second CU are the same node.

[0124] Optionally, in an embodiment of the present application, before sending the first notification message to the second node device, the first node device may first send a cell switching command to the terminals allocated the same CG resources of the first cell based on the measurement result of the first cell, simultaneously or in succession within a short period of time. After a terminal receives the corresponding cell switching command, if the terminal obtains the TA value of the first cell, the terminal executes a RACH-less switching process based on the configuration authorization, and monitors the physical downlink control channel (PDCCH) of the first cell at the same time. If uplink scheduling is monitored, the terminal executes a RACH-less switching process based on dynamic scheduling; if the terminal does not obtain the TA value of the first cell, the terminal executes a RACH-based switching process.

[0125] Step 502: The second node device determines, based on the first notification message, whether the CG resources corresponding to the second terminal conflict with the CG resources corresponding to other terminals.

[0126] Optionally, in an embodiment of the present application, the CG resources corresponding to the above-mentioned second terminal may be: the CG resources allocated by the above-mentioned second node device to the second terminal.

[0127] Optionally, in the embodiment of the present application, the above step 502 can be specifically implemented through the following step 502a.

[0128] Step 502a: The second node device determines whether the CG resources corresponding to the second terminal conflict with the CG resources corresponding to other terminals based on the CG resources corresponding to the second terminal and the TCI status identifier corresponding to the second terminal.

[0129] Optionally, in an embodiment of the present application, the second terminal and the other terminals may both be terminals corresponding to the first node device.

[0130] Optionally, in an embodiment of the present application, if the CG resources corresponding to the above-mentioned second terminal are the same as the CG resources corresponding to at least one other terminal, and the TCI status identifier corresponding to the second terminal is the same as the TCI status identifier corresponding to at least one other terminal, then the second node device can determine that the CG resources corresponding to the second terminal and the CG resources corresponding to the other terminals are in conflict; if the CG resources corresponding to the above-mentioned second terminal are different from the CG resources corresponding to any other terminal, and the TCI status identifier corresponding to the second terminal is different from the TCI status identifier corresponding to any other terminal, then the second node device can determine that the CG resources corresponding to the second terminal and the CG resources corresponding to the other terminals do not conflict.

[0131] In an embodiment of the present application, since the second node device can determine whether the CG resources corresponding to the second terminal conflict with the CG resources corresponding to other terminals based on the CG resources allocated to the above-mentioned second terminal and the TCI status identifier corresponding to the second terminal, and the TCI status identifier can clearly indicate the TCI status, the second node device can accurately determine whether the CG resources corresponding to the second terminal conflict with the CG resources corresponding to other terminals.

[0132] Step 503: In the event of a conflict, the second node device dynamically schedules the second terminal and at least some of the other terminals to perform uplink data transmission.

[0133] The specific method of dynamically scheduling at least part of the terminals to perform uplink data transmission by the second node device can refer to the relevant description in the relevant technology, and will not be described here to avoid repetition.

[0134] In the resource scheduling method provided in the embodiment of the present application, since the second node device can determine whether the CG resources corresponding to the second terminal conflict with the CG resources corresponding to other terminals based on the first notification message received from the first node device, and dynamically schedule the second terminal and at least some of the other terminals to perform uplink data transmission when there is a conflict, when the at least some of the terminals simultaneously initiate RACH-less switching, it can avoid excessive RACH-less switching delay or even switching failure of some terminals caused by the conflict of CG resources used by the at least some of the terminals.

[0135] Optionally, in an embodiment of the present application, before the above step 501, the resource scheduling method provided in the embodiment of the present application may further include the following step 504.

[0136] Step 504: The second node device allocates the same CG resources to multiple terminals corresponding to the first node device.

[0137] In an embodiment of the present application, since the second node device can allocate the same CG resources to multiple terminals corresponding to the first node device, the second node device dynamically schedules at least some of the above-mentioned terminals to perform uplink data transmission, which can avoid the RACH-less switching delay of some terminals being too long or even the switching failure caused by the conflict of CG resources used by the multiple terminals.
