The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the present disclosure and should not be construed as a limitation of the present disclosure.

When the network device is configured with separate MBS for the terminal device, in order to solve the problem of how to realize the fast switching of the receiving mode, the embodiments of the present disclosure provide a method, apparatus and communication device for determining the receiving mode, so as to determine the receiving mode according to the trigger condition or the indication information of the network device. , to achieve fast switching of the receiving mode of the separated MRB.

FIG. 1 is a schematic flowchart of a method for determining a receiving mode according to an embodiment of the present disclosure, which is executed by a terminal device. As shown in Figure 1, the method for determining the receiving mode includes the following steps:

Step 101: Receive first indication information sent by a network device, where the first indication information is used to indicate a receiving mode for separating MRBs.

The split MRB of the present disclosure may be a carrier aggregation (Carrier Aggregation, CA) split MRB, or a dual connectivity (Dual Connectivity, DC) split MRB. As shown in Figure 2 and Figure 3, for CA separation MRB and DC separation MRB, one Packet Data Convergence Protocol (PDCP) can be associated with two Radio Link Control (Radio Link Control, RLC) entities (ie 2 different receiving paths), the data of 1 RLC entity can be sent through G-RNTI PDCCH scheduling, that is, through point-to-multipoint (PTM) transmission, that is, multicast transmission; the other 1 The data of each RLC entity can be scheduled and sent through the Cell-Radio Network Temporary Identifier (C-RNTI) PDCCH, that is, a point-to-point (PTP) transmission, that is, a unicast transmission.

The CA shown in FIG. 2 separates the MRB, and two RLC entities are associated with one medium access control (Medium Access Control, MAC) entity. As shown in Figure 3, the DC separates the MRB, and two RLC entities are associated with two different MAC entities. For example, RLC-1 is associated with the Master Cell Group (MCG) MAC, and RLC-2 is associated with the Secondary Cell Group (Secondary Cell Group). Group, SCG) MAC).

The terminal equipment can configure two cell groups MCG and SCG at the same time. The MCG may include at least one primary cell (Primary Cell, PCell), and may also include one or more secondary cells (Secondary Cell, SCell); the SCG includes at least one primary secondary cell (Primary Secondary Cell, PSCell), One or more SCells may also be included.

In the present disclosure, the receiving mode of separate MRB may include receiving only through PTM (eg, indicating reception through G-RNTI PDCCH scheduling, receiving through PTP only (eg, indicating receiving through C-RNTI PDCCH scheduling), and simultaneously through PTM and PDCCH scheduling. Receive in PTP mode (for example, indicating that the receiving is scheduled through G-RNTI PDCCH and C-RNTI PDCCH at the same time), etc.

The terminal device may receive the first indication information sent by the network device, where the first indication information is used to indicate the receiving mode of the separated MRB. Optionally, the first indication information may also be used to indicate at least one of the following: the changed bearer receiving mode; the activation state of the changed bearer receiving mode; the changed path receiving mode of the designated receiving path; the activation state; and the activation state of the changed path reception mode of the specified reception path.

Step 102 , according to the first indication information, determine the receiving mode after the separation of the MRB changes.

In the present disclosure, the terminal device may determine, according to the first indication information, the receiving mode after the separation of the MRB changes.

For the convenience of description, it can be specified that the receiving mode 1 is only through the PTM mode, the receiving mode 2 is only the receiving through the PTP mode, and the receiving mode 3 is the receiving through the PTM and the PTP mode at the same time. For example, the split MRB has two receive paths, namely path-1 and path-2. The network device configures the split MRB path-1 as receive mode 1 and the split MRB path-2 as receive mode 2. If the indication information indicates that the reception mode is reception mode 1, then the terminal device can determine, according to the first indication information, that the reception mode after the separation of the MRB changes is reception mode 1, that is, the reception mode is only received through PTM, so that the terminal device uses path-1 to use Receive MBS services in PTM mode.

In the present disclosure, the activation state may include "activated" and "deactivated". For example, the network device configures path-1 of the split MRB as receiving mode 1 and path-2 as receiving mode 2, and configures the split MRB with receiving mode 1, receiving mode 2 and receiving mode 3. If the first indication information indicates to activate the reception mode 1 of the split MRB, the terminal device determines that the modified reception mode of the split MRB is the reception mode 1, that is, only received in the PTM mode, so that the terminal device receives the MBS service through path-1. If the first indication message indicates that the receiving mode 3 is activated, the terminal device receives the MBS service through the path-1 and the path-2 at the same time.

In the embodiment of the present disclosure, the terminal device may receive the first indication information sent by the network device, and determine the changed reception mode of the separated MRB according to the first indication information, thereby realizing fast switching of the separated MRB reception mode.

FIG. 4 is a schematic flowchart of another method for determining a receiving mode according to an embodiment of the present disclosure. The method for determining a receiving mode may be performed by a terminal device.

As shown in Figure 4, the method for determining the receiving mode includes the following steps:

Step 401: Receive first indication information sent by a network device based on a specified type of signaling.

In the present disclosure, the terminal device may receive the first indication information sent by the network device based on the specified type of signaling. Wherein, the first indication information may be used to indicate the receiving mode of the separated MRB.

Optionally, the signaling of the specified type may be any of the following: radio resource control (Radio Resource Control, RRC) signaling, PDCP signaling, MAC signaling, and physical channel control signaling. The physical channel control signaling may be, for example, downlink control information (Downlink Control Information, DCI) of the PDCCH channel. The specified type of signaling here may be agreed through a standard or a protocol.

In the present disclosure, the first indication information may also be used to indicate at least one of the following: a changed bearer receiving mode; an activation state of the changed bearer receiving mode; a changed path receiving mode for specifying a receiving path; the activation state; and the activation state of the changed path reception mode of the specified reception path.

The activation state may include "activated" and "deactivated". For example, there are two receiving paths, namely path-1 and path-2, and the first indication information indicates that the activation state of the designated receiving path-1 is "active".

Optionally, the first indication information may include at least one of the following: a separate MRB identifier; type information of the changed bearer receiving mode; activation state information corresponding to the changed bearer receiving mode; an identifier of a designated receiving path; The activation state information corresponding to the path; and the type information of the changed path receiving mode corresponding to the designated receiving path.

In the present disclosure, if the first indication information indicates the changed bearer reception mode, the first indication information may include the separated MRB identifier and the type information of the changed bearer reception mode. If the first indication information indicates activation state information corresponding to the changed bearer reception mode, the first indication information may include a separate MRB identifier, type information of the changed bearer reception mode, and activation state information corresponding to the changed bearer reception mode.

If the first indication information indicates the activation state of the designated receiving path, the first indication information may include a separate MRB identifier, an identifier of the designated receiving path, and activation state information corresponding to the designated receiving path. If the first indication information indicates a changed path reception mode of the designated reception path, the first indication information may include a separate MRB identifier, an identifier of the designated reception path, and type information of the changed path reception mode corresponding to the designated reception path. If the first indication information indicates the activation state of the changed path reception mode of the designated reception path, the first indication information may include a separate MRB identifier, an identifier of the designated reception path, and the type of the changed path reception mode corresponding to the designated reception path information, the activation status information of the changed path reception mode corresponding to the specified reception path.

Optionally, the designated receiving path identifier includes at least one of the following: a logical channel identifier, an RLC entity identifier, a cell identifier, a cell type identifier, and a cell group identifier. The cell type identifier may be one of PCell, SCell, PSCell, and special cell (Special Cell, SpCell), and PCell and PSCell may be collectively referred to as SpCell.

Step 402, according to the first indication information, determine the receiving mode after the separation of the MRB changes.

If the first indication information includes the separated MRB identifier and the type information of the changed bearer reception mode, that is, the first indication information indicates the changed bearer reception mode. For example, if the separated MRB identifier is MRB-1, and the changed bearer receiving mode is receiving mode 1, the terminal device may determine that the changed receiving mode of MRB-1 is receiving mode 1.

If the first indication information includes the separated MRB identifier, the type information of the changed bearer reception mode, and the activation state information corresponding to the changed bearer reception mode, the first indication information indicates the activation state information corresponding to the changed bearer reception mode. For example, the network device configures the path-1 of the separated MRB identified as MRB-1 to receive mode 1, configures the path-2 of MRB-1 to receive mode 2, and configures the MRB-1 with receive mode 1 and receive mode Mode 2 and receiving mode 3, if the first indication information sent by the network device includes the separated MRB identifier as MRB-1, the changed bearer receiving mode is receiving mode 1, and the activation state information corresponding to the changed bearer receiving mode is "Activate". ”, then the terminal equipment can receive the MBS service through path-1 of MRB-1.

If the first indication information indicates the activation state of the designated receiving path, the terminal device may determine, according to the first indication information, the receiving mode after the separation of the MRB changes. For example, the network device configures the path-1 of MRB-1 as receiving mode 1, and configures the path-2 of MRB-1 as receiving mode 2. If the first indication information indicates that path-1 is activated and indicates that path-2 is deactivated, the terminal device adopts reception mode 1 for MRB-1. If the first indication message indicates deactivation of path-1 and activation of path-2, the terminal device adopts reception mode 2 for MRB-1. If the first indication message indicates that the path-1 is activated and the path-2 is activated, the terminal device adopts the receiving mode 3 for the MRB-1.

If the first indication information indicates the activation state of the changed path receiving mode of the designated receiving path, the terminal device may determine the changed receiving mode after separating the MRB according to the first indication information. For example, the network device configures the path-1 of MRB-1 as receiving mode 1, receiving mode 2 and receiving mode 3, and configures the path-2 of MRB-1 as receiving mode 1, receiving mode 2 and receiving mode 3, the first The indication information can indicate that path-1 of MRB-1 activates reception mode 1, and path-2 of MRB-1 activates reception mode 2. The terminal device can determine that path-1 adopts reception mode 1 to receive MBS services, and path-2 adopts reception mode 2. Receive MBS services.

Optionally, the terminal device may further determine the bearer receiving mode in the first indication information as the bearer receiving mode of the MRB. For example, the bearer reception modes in the first indication message include reception mode 1, reception mode 2, and reception mode 3, and the terminal may determine the three reception modes as the bearer reception modes of the MRB.

Alternatively, the terminal device may also determine the path reception mode in the first indication information as the path reception mode of the designated reception path of the MRB. For example, the path reception mode in the first indication message is reception mode 1, and the terminal device may determine reception mode 1 as the reception mode of the designated reception path of the MRB.

In the embodiment of the present disclosure, the terminal device may receive the first indication information sent by the network device based on the signaling of the specified type, and then determine the changed reception mode of the separated MRB according to the first indication information, thereby realizing the separated MRB reception mode fast switching.

FIG. 5 is a schematic flowchart of another method for determining a receiving mode according to an embodiment of the present disclosure. The method for determining a receiving mode may be performed by a terminal device.

As shown in Figure 5, the method for determining the receiving mode includes the following steps:

Step 501: Receive first indication information sent by a network device, where the first indication information is used to indicate a receiving mode for separating MRBs.

In the present disclosure, step 501 may be implemented in any one of the various embodiments of the present disclosure, which is not limited in the embodiments of the present disclosure, and will not be described again.

Step 502: Determine, according to the first indication information, a receiving mode after the split MRB is changed.

Optionally, the change of the reception mode may include the change of the bearer reception mode, the change of the reception mode of the designated reception path, and the like.

For example, if the receiving mode of the separated MRB is changed from receiving mode 1 (or receiving mode 3) to receiving mode 2, the terminal device can stop the MBS wireless network temporary identity (MBS Radio Network Temporary Identity, M-RNTI) PDCCH corresponding to the separated MRB. monitoring.

For another example, if the reception mode of Path-1 for separating MRBs is changed from reception mode 1 (or reception mode 3) to reception mode 2, the terminal device may stop monitoring the M-RNTI PDCCH corresponding to Path-1 for separating MRBs.

Optionally, the change of the activation state includes the activation state of the bearer reception mode, the activation state of the designated reception path, the activation state of the reception mode of the designated reception path, and the like.

For another example, for the activation state of the designated reception path, if the activation state of the designated reception path whose reception mode is reception mode 1 or reception mode 3 is changed to deactivation, the terminal device can stop monitoring the M-RNTI PDCCH corresponding to the split MRB.

For another example, for the activation state of the reception mode of the designated reception path, if the activation state of reception mode 1 is changed to deactivated, or the activation state of reception mode 2 is changed to activated, or the activation state of reception mode 3 is changed to deactivated, etc., Stop monitoring the M-RNTI PDCCH corresponding to the split MRB.

In this embodiment of the present disclosure, the terminal device may receive the first indication information sent by the network device, and according to the first indication information, determine the changed reception mode of the separated MRB, change the reception mode of the separated MRB, or change the reception mode of the separated MRB In the corresponding active state, the monitoring of the channel corresponding to the receiving mode before the change can be stopped, which not only realizes the fast switching of the receiving mode, but also stops the monitoring of the channel corresponding to the receiving mode before the change, saving power consumption.

FIG. 6 is a schematic flowchart of another method for determining a receiving mode according to an embodiment of the present disclosure. The method for determining a receiving mode may be performed by a terminal device.

As shown in Figure 6, the method for determining the receiving mode includes the following steps:

Step 601: Receive second indication information sent by a network device, where the second indication information is used to indicate a trigger condition.

In the present disclosure, the network device can send the second indication information to the terminal device, so that the terminal device can receive the second indication information sent by the network device. Wherein, the second indication information is used to indicate a trigger condition.

Optionally, the trigger condition may include at least one of the following: condition indication information; separation MRB identification; and separation MRB receiving path identification. Wherein, the condition indication information in the trigger condition corresponds to the identification of the separated MRB and the identification of the receiving path of the separated MRB.

Optionally, the condition indication information may include at least one of the following: a measurement signal threshold value; a data packet loss threshold value; a changed receiving mode; and a changed activation state.

In the present disclosure, the threshold value of the measured signal may be the threshold value of the reference signal received strength (Reference Signal Received Power, RSRP), or the threshold value of the reference signal received quality (Reference Signal Received Quality, RSRQ), or the signal The threshold value of Signal to Interference and Noise Ratio (SINR), or the threshold value of Received Signal Strength Indicator (RSSI), or the threshold value of Channel Occupancy Rate (COR) The limit value, or the threshold value of the channel busy ratio (Channel Busy Ratio, CBR), or the threshold value of the channel occupancy time (Channel Occupancy Time, COT), etc.

The data packet loss threshold value may be the threshold value of the PDCP data packet loss quantity, the RLC data packet loss quantity threshold value, the MAC data packet loss quantity threshold value, and the like.

Step 602 , according to the trigger condition, determine the received mode after the split MRB is changed.

In the present disclosure, the terminal device may determine the receiving mode after the separation of the MRB changes according to the trigger condition.

Optionally, the terminal device may change the receiving mode of the designated receiving path of the separated MRB, or the activation state of the designated receiving path, or the activation state of the receiving mode of the designated receiving path, etc., according to the measurement signal threshold value in the trigger condition. .

For example, for Path-1 with MRB separation, when the RSRP or RSRQ or SINR of the cell corresponding to Path-1 is greater than or equal to the corresponding threshold (or, RSSI or COR or CBR or COT is less than or equal to the corresponding threshold ), the receive mode of path-1 is changed to receive mode 1. Or, when the RSRP or RSRQ or SINR of the cell corresponding to the path is less than or equal to the corresponding threshold value (or, RSSI or COR or CBR or COT is greater than or equal to the corresponding threshold value), the reception mode of path-1 is changed to Receive mode 2.

Optionally, the terminal device may also change the bearer receiving mode of the separated MRB, or the activation state of the bearer receiving mode, etc., according to the threshold value of the measurement signal in the trigger condition.

For example, the network device is configured to receive mode 1 for path-1 for separating MRBs, and configure path-2 to receive mode 2. When the RSRP or RSRQ or SINR of the cell corresponding to the split MRB is greater than or equal to the corresponding threshold value (or, the RSSI or COR or CBR or COT is less than or equal to the corresponding threshold value), the reception mode of the split MRB is changed to Receive mode 1. Or, when the RSRP or RSRQ or SINR of the cell corresponding to the separated MRB is less than or equal to the corresponding threshold value (or, RSSI or COR or CBR or COT is greater than or equal to the corresponding threshold value), the receiving mode of the separated MRB is Change to receive mode 2 or receive mode 3.

Optionally, the terminal device may, according to the threshold value of the packet loss amount in the trigger condition, separate the receiving mode of the designated receiving path of the MRB, or the activation state of the designated receiving path, or the activation state of the receiving mode of the designated receiving path, etc. make changes.

For example, for the path-1 of the separated MRB, when the number of packet losses corresponding to the path-1 is less than or equal to the threshold value of the data packet loss, the receiving mode of the path-1 of the separated MRB is changed to the receiving mode 1. Alternatively, when the number of packet losses corresponding to the path is greater than or equal to the threshold value of the packet loss amount, the receiving mode of the path-1 of the separated MRB is changed to the receiving mode 2.

Optionally, the terminal device may also change the bearer receiving mode of the separated MRB, or the activation state of the bearer receiving mode, etc., according to the data packet loss threshold value in the trigger condition.

For example, the path-1 of the separated MRB is configured as receiving mode 1, and the path-1 of MRB-2 is configured as receiving mode 2. When the number of packet losses corresponding to the split MRB is less than or equal to the threshold value of the packet loss amount, the receiving mode of the split MRB is changed to receiving mode 1 . or. When the number of packet losses corresponding to the split MRB is greater than or equal to the threshold value of the packet loss amount, the receiving mode of path-1 of the split MRB is changed to receiving mode 2 or receiving mode 3.

Optionally, in the case of changing the bearer receiving mode or the receiving mode of the designated receiving path, it can indicate the changed receiving mode when the receiving mode change condition is satisfied, so that when the receiving mode changing condition is satisfied, The terminal device can determine the changed reception mode. For example, the changed reception mode may be reception mode 1, reception mode 2, or reception mode 3.

Optionally, in the case of changing the activation state of the designated receiving path, or the activation state of the receiving mode of the designated receiving path, or the activation state of the bearer receiving mode, etc., it can be indicated that if the conditions for changing the activation state are met, after the change so that the terminal device can determine the activation state after the change when the condition for changing the reception mode is satisfied. For example, the changed activation status is "activated" or "deactivated".

In this embodiment of the present disclosure, the terminal device can receive the second indication information sent by the network device, where the second indication information is used to indicate a trigger condition, and then according to the trigger condition, determine the received mode after the separation of the MRB changes, so that by using the trigger condition , to achieve fast switching of separate MRB receiving modes.

In an embodiment of the present disclosure, the terminal device can receive second indication information sent by the network device, where the second indication information is used to indicate a trigger condition, and according to the trigger condition, determine the receiving mode after the change of the separated MRB, and after the change When the receiving mode of the separated MRB is separated, or the activation state corresponding to the receiving mode of the separated MRB is changed, the monitoring of the channel corresponding to the receiving mode before the change can be stopped, which not only realizes the fast switching of the receiving mode, but also stops the receiving mode before the change. The monitoring of the corresponding channel saves power consumption.

In an embodiment of the present disclosure, the terminal device may determine the receiving mode after the change of the separated MRB according to the trigger condition or the first indication information sent by the network device, when changing the receiving mode of the separated MRB, or changing the corresponding receiving mode of the separated MRB In the activated state, the PDCP data receiving state information can be reported to the network device through the changed unicast path of the separated MRB, such as reporting the PDCP state report.

For example, the bearer reception mode is changed from reception mode 2 (or reception mode 3 ) to reception mode 1 , or from reception mode 2 to reception mode 3 . In another example, the reception mode of the designated reception path is changed from reception mode 2 (or reception mode 3 ) to reception mode 1 , or from reception mode 2 to reception mode 3 .

For example, for the activation state of bearer reception mode, if reception mode 1 is changed from activation to deactivation, or reception mode 2 is changed from deactivation to activation, or reception mode 3 is changed from deactivation to activation, or reception mode 3 From activation to deactivation, the terminal device can report the PDCP data reception status information to the network device through the changed unicast path of the separated MRB.

For another example, for the activation state of the designated receiving path, if the receiving mode is the receiving path of receiving mode 1 or receiving mode 3, and the activation state of the receiving path is changed from activated to deactivated, the terminal device can pass the changed separation MRB. The unicast path reports PDCP data reception status information to the network device.

Step 901: Send second indication information to the terminal device, where the second indication information is used to indicate a trigger condition for changing the receiving mode of the separated MRB.

In the present disclosure, the network device can send the second indication information to the terminal device, so that the terminal device can receive the second indication information sent by the network device. The second indication information is used to indicate a trigger condition for changing the split MRB.

Optionally, the network device may use the threshold value of the measurement signal in the trigger condition to indicate the receiving mode of the designated receiving path of the separated MRB, or the activation state of the designated receiving path, or the activation state of the receiving mode of the designated receiving path, etc. change.

Optionally, the network device may also instruct to change the bearer receiving mode of the separated MRB, or the activation state of the bearer receiving mode, etc., through the threshold value of the measurement signal in the trigger condition.

For example, the network device is configured to receive mode 1 for path-1 for separating MRBs, and configure path-2 to receive mode 2. The network device may indicate that when the RSRP or RSRQ or SINR of the cell corresponding to the separated MRB is greater than or equal to the corresponding threshold value (or, the RSSI or COR or CBR or COT is less than or equal to the corresponding threshold value), the receiving of the separated MRB The mode is changed to receive mode 1.

For example, for the path-1 of the separated MRB, when the number of packet losses corresponding to the path-1 is less than or equal to the threshold value of the data packet loss, the receiving mode of the path-1 of the separated MRB is changed to the receiving mode 1.

Optionally, the network device may also instruct to change the bearer receiving mode of the separated MRB, or the activation state of the bearer receiving mode, etc., through the threshold value of the packet loss amount in the trigger condition.

For example, the path-1 of the separated MRB is configured as receiving mode 1, and the path-1 of MRB-2 is configured as receiving mode 2. When the number of packet losses corresponding to the split MRB is less than or equal to the threshold value of the packet loss amount, the receiving mode of the split MRB is changed to receiving mode 1 .

In this embodiment of the present disclosure, the network device may send the second indication information to the network device, and the second indication information may indicate the receiving mode after the change of the separated MRB, so that the terminal device may determine, according to the second indication information, the changed reception mode of the separated MRB.

FIG. 10 is a schematic flowchart of another method for determining a receiving mode according to an embodiment of the present disclosure. The method for determining a receiving mode may be performed by a network device.

As shown in Figure 10, the method for determining the receiving mode includes the following steps:

Step 1001: Receive third indication information sent by another network device, where the third indication information is used to indicate a changed reception mode after separating the MRB.

In the present disclosure, when the split MRB is a DC split MRB, the network device may receive third indication information sent by another network device to negotiate with the other network device about the changed reception mode of the split MRB. The third indication information may be used to indicate the changed reception mode of the separated MRB, and may also be used to indicate the activation state of the changed reception mode, the activation state of the designated reception path, and the like.

The network device can be any one of a master node (Master Node, MN) and a secondary node (Secondary Node, SN), and the other network device is the other one of the MN and the SN. Among them, the MN is used to manage the MCG, and the SN is used to manage the SCG.

Alternatively, the network device may be any one of a centralized unit (Centralized Unit, CU) and a distributed unit (Distributed Unit, DU), and the other network device is the other of the CU and the DU. Wherein, the CU may include the RRC entity and the PDCP entity, and the DU may include the RLC and the MAC entity.

Step 1002, according to the third indication information, change the receiving mode of the separated MRB.

In the present disclosure, the network device may change the receiving mode of the separated MRB according to the third indication information.

For example, the SN receives the third indication information sent by the MN, where the third indication information is used to specify the receiving mode of the SCG path where the DC separates the MRB. After the SN accepts the MN's instruction, the SN uses the receiving mode to send the MBS data of the SCG path of the DC-separated MRB. If the SN does not accept the receiving mode of the SCG path indicated by the MN, the SN may refuse to establish the SCG path of the DC split MRB, or the SN indicates to the MN the receiving mode of the SCG path of the DC split MRB it uses.

For another example, the SN receives third indication information sent by the MN, where the third indication information specifies that the reception mode of the MCG path of the DC split MRB is reception mode 1 or reception mode 2. The SN accepts the receiving mode of the MCG path indicated by the MN, and the SN can determine the receiving mode of the SCG path of the DC separated MRB according to the receiving mode of the MCG path of the DC separated MRB, for example, the MN indicates that the receiving mode of the MCG path of the DC separated MRB is the receiving mode 1, the SN determines that the receiving mode of the SCG path of the DC split MRB is the receiving mode 2. Further, after determining the reception mode of the SCG path of the DC split MRB, the SN may notify the MN of the determined reception mode of the SCG path of the DC split MRB.

For another example, the SN receives the third indication information sent by the MN, where the third indication information specifies the receiving mode of the SCG path of the DC separated MRB and the receiving mode of the MCG path of the DC separated MRB. For example, for the case where the PDCP of the DC split MRB is on the MN (or MCG), the MN can instruct the SN that the reception mode of the MCG path of the DC split MRB is reception mode 1, and the reception mode of the SCG path of the DC split MRB is Receive mode 2.

For another example, the MN receives the third indication information sent by the SN, where the third indication information specifies the receiving mode of the SCG path of the DC separated MRB and the receiving mode of the MCG path of the DC separated MRB. For example, in the case where the PDCP of the DC split MRB is on the SN (or SCG), the SN can instruct the MN that the reception mode of the MCG path of the DC split MRB is reception mode 1, and the reception mode of the SCG path of the DC split MRB is Receive mode 2.

For another example, the DU receives third indication information sent by the CU, where the third indication information specifies the reception mode of the MRB reception path. For example, the DU receives the third indication information sent by the CU, wherein the third indication information specifies that the receiving mode of path-1 of the DC split MRB is the receiving mode 1 or the receiving mode 2, then the DU can be based on the receiving mode specified by the CU. The DC separates the path-1 of the MRB for data transmission.

Alternatively, the third indication information received by the DU may also indicate the activation state of the receiving path, and the CU sends the indication information to the DU to specify the activation state of the path-1 of the DC separation MRB, then the DU according to the activation state of the path-1 specified by the CU, in the When path-1 is activated, data transmission is performed in the receive mode corresponding to the path-1.

Optionally, the network device may send fourth indication information to another network device when the receiving mode of the separated MRB is not changed, where the fourth indication information is used to indicate that the receiving mode of the separated MRB is not changed.

For example, when the changed receiving mode of the split MRB indicated by the third indication information sent by another network device is the same as the current receiving mode of the split MRB, the receiving mode of the split MRB is not changed, and a fourth message is sent to the other network device. Indication information to notify another network device that the receive mode of the split MRB has not been changed.

Step 1003: Send first indication information to the terminal device, where the first indication information is used to indicate the receiving mode of the separated MRB.

In the present disclosure, step 1003 may be implemented by any one of the various embodiments of the present disclosure, which is not limited in the embodiments of the present disclosure, and will not be described again.

In this embodiment of the present disclosure, when the split MRB is a DC split MRB, the network device may receive third indication information sent by another network device, change the receiving mode of the split MRB according to the third indication information, and then send the first message to the terminal device. The indication information indicates the changed reception mode of the separated MRB through the first indication information, so that the terminal device determines the changed reception mode of the separated MRB according to the first indication information, thereby realizing fast switching of the separated MRB reception mode.

Optionally, the network device may also send second indication information to the terminal device after changing the receiving mode of the separated MRB according to the third indication information sent by another network device, and use the second indication information to instruct the change of the separation MRB. The trigger condition of the receiving mode is to enable the terminal device to determine the changed receiving mode of the separated MRB according to the second indication information, so as to realize the fast switching of the separated MRB receiving mode.

In an embodiment of the present disclosure, the network device may also send fifth indication information to another network device, where the fifth indication information is used to instruct the other network device to instruct the receiving mode after the MRB is separated and changed. Another network device may send, according to the fifth indication information, indication information to the network device to indicate the changed reception mode after separating the MRB. The network device can change the receiving mode of the separated MRB according to the indication information.

For example, the MN sends fifth indication information to the SN to request the SN to determine the receiving mode of the SCG path where the DC separates the MRB. After the SN determines the reception mode of the SCG path of the DC separated MRB, the SN notifies the MN of the reception mode of the SCG path of the DC separated MRB.

Further, according to the receiving mode of the SCG path of the DC separated MRB notified by the SN to the MN, the MN can configure the corresponding receiving mode of the MCG path of the DC MN MRB. For example, if the SN informs the MN that the receiving mode of the SCG path of the DC split MRB is receiving mode 1, the MN configures the receiving mode of the MCG path of the DC split MRB to be the receiving mode 2.

For another example, the SN requests or informs the MN that it has changed the receiving mode of the SCG path. For example, the current reception mode of the SCG path of the DC split MRB is reception mode 1, and the SN wishes to change the reception mode of the SCG path of the DC split MRB to reception mode 2. Then the SN can send indication information to the MN to request or notify the MN that it wishes to change the receiving mode of the SCG path of the DC split MRB to receiving mode 2.

Further, the MN can decide whether the receiving mode 2 of the SCG path of the DC split MRB requested by the SN is allowed, and indicate the allowed receiving mode of the SCG path of the DC split MRB to the SN through the indication information. The receiving mode of the SCG path of the DC separated MRB allowed by the MN may be the same as or different from the receiving mode of the SCG path of the DC separated MRB requested by the SN.

For another example, the CU sends fifth indication information to the DU to request the DU to indicate the receiving mode of the receiving path where the DC separates the MRB. For example, the CU sends indication information to the DU to request the DU to determine the receiving mode of path-1 of the DC split MRB. After the DU determines the receiving mode of the path-1 of the DC-separated MRB, the DU notifies the CU of the receiving mode of the path-1 of the DC-separated MRB.

For another example, the DU may request or notify the CU that it has changed the receive mode of the receive path of the DC split MRB. For example, the current receiving mode of path-1 of the DC split MRB is receiving mode 1, and the DU wants to change the receiving mode of path-1 to receiving mode 2, then the DU can send an indication message to the CU to request or Notify the CU that it wishes to change the receive mode of path-1 of the DC split MRB to receive mode 2.

Further, the CU may decide whether the receiving mode 2 of path-1 of the DC split MRB requested by the DU is allowed, and indicate the allowed receiving mode of the path-1 of the DC split MRB to the DU through the indication information. The receiving mode of the path-1 of the DC-separated MRB allowed by the CU may be the same as or different from the receiving mode of the path-1 of the MRB-1 requested by the DU.

Optionally, the fifth indication information may also be used to instruct another network device to indicate the activation state of the reception mode, the activation state of the reception path, and the like after the separation of the MRB changes.

For example, the DU may request or notify the CU to indicate the active state of the receive path. For example, the current reception mode of path-1 of the DC split MRB is reception mode 1, and the activation state of reception mode 1 of this path-1 is active. If the DU wishes to change the activation status of the receiving mode 1 of the path-1 of the DC split MRB to deactivated, the DU requests or informs the CU that it wishes to change the active status of the receiver mode 1 of the path-1 of the DC split MRB to deactivated.

Further, the CU may determine whether the activation state of the receiving mode 1 of the path-1 of the DC split MRB requested by the DU is allowed, and indicate the enabled status of the receiving mode 1 of the path-1 of the DC split MRB to the DU. . Wherein, the activation state of the receiving mode 1 of the path-1 of the DC separated MRB allowed by the CU may be the same as or different from the activation state of the receiving mode of the path-1 of the DC separated MRB requested by the DU.

In this embodiment of the present disclosure, the network device may send fifth indication information to another network device, where the fifth indication information is used to instruct the other network device to instruct the receiving mode after separation of the MRB changes, so that another network device may be used to indicate The received mode after the change of the separated MRB is determined, and the received mode after the change of the separated MRB is determined through negotiation.
