Description

Technical Field

[0001] The embodiments of the present invention relate to the field of wireless communication technology, and in particular to a reporting and configuration method for auxiliary node link failure, a terminal, and a network-side device. Background Art

[0002] In the dual-link scenario, a new terminal capability is defined, namely, the capability to support dynamic power sharing, which means that when the total transmission power of the two links of the dual link exceeds the "transmission power limit PEN-DC,tot_L", the transmission power of the auxiliary node link can be reduced or the uplink transmission of the auxiliary node link can be interrupted to ensure that the total transmission power of the dual link is less than or equal to the transmission power limit PEN-DC,tot_L. The "transmission power limit PEN-DC,tot_L" mentioned above refers to the maximum uplink total transmission power actually allowed in the dual link scenario defined to ensure the transmission power, interference, anti-interference and other indicators in the dual link scenario. The judgment criteria for reducing power or interrupting uplink transmission are as follows: In order to ensure the dual link transmission power limit PEN-DC,tot_L, if the power value that the auxiliary node link needs to reduce is greater than the threshold "X_scale" configured by the network, the uplink transmission of this link is terminated; if the reduced power value is lower than the threshold "X_scale" configured by the network, the transmission power of the auxiliary node link is reduced to the target power value.

[0076] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0077] By actively reducing the transmission power of the auxiliary node link or interrupting the uplink transmission of the auxiliary node link, and reducing the total transmission power of the two links of the main and auxiliary nodes, the terminal supporting dynamic power sharing capability is more likely to experience uplink and downlink failures or even retransmission failures. Among them, downlink failure is mainly caused by uplink feedback link failure, such as uplink HARQ (Hybrid Automatic Repeat reQuest) feedback failure causing downlink failure.

[0078] From the perspective of the network side, there are many reasons for the failure of the wireless link, and the network side is not clear about the specific reasons that caused the wireless link failure of the terminal. The reasons for the failure of the wireless link include: the auxiliary node link of the terminal supporting dynamic power sharing interrupts the uplink transmission, the wireless link fails after the terminal supporting dynamic power sharing reduces the transmission power of the auxiliary node link, the auxiliary node handover fails, the auxiliary node configuration fails, the auxiliary node RRC integrity protection detection fails, etc.

[0079] Therefore, the network side cannot quickly solve the wireless link failure problem caused by dynamic power sharing, and can only maintain the secondary node link failure state or send and receive secondary node data through the primary node. However, both methods lose the dual link advantage, greatly reduce spectrum efficiency, and increase operator operating costs.

[0080] To solve the above problems, an embodiment of the present invention provides a reporting and configuration method for auxiliary node link failure, a terminal and a network-side device. If the terminal causes a wireless line failure due to supporting dynamic power sharing, the reported failure cause indicates that it is caused by supporting power sharing, so that the network side can perform corresponding wireless resource configuration adjustments according to the cause, thereby ensuring the advantages of dual links, improving spectrum efficiency, and reducing operator operating costs.

[0081] Please refer to Figure 1 , Figure 1 The flowchart of the method for reporting a secondary node link failure according to an embodiment of the present invention is applied to a terminal, including:

[0082] Step 11: reporting indication information indicating the cause of the auxiliary node link failure to the network side device, where the indication information is used to indicate that the auxiliary node link failure is caused by the terminal supporting dynamic power sharing.

[0083] In an embodiment of the present invention, if a wireless line failure occurs due to support for dynamic power sharing by a terminal, the reported failure cause indicates that it is caused by support for power sharing, so that the network side can perform corresponding wireless resource configuration adjustments according to the cause, thereby ensuring the dual-link advantage, improving spectrum efficiency, and reducing operator operating costs.

[0084] Optionally, the indication information is reported via SCG failure cause indication information or via other information.

[0085] In the embodiment of the present invention, when the sum of the transmission power of the terminal master node and the auxiliary node exceeds the threshold value "PEN-DC, tot_L" specified by the standard, the terminal needs to reduce the transmission power of the auxiliary node to ensure that the power sum is lower than the threshold value "PEN-DC, tot_L". If the power value that needs to be reduced by the auxiliary node link exceeds the threshold X_scale configured by the network, the terminal stops the auxiliary node uplink transmission and reports the failure reason, that is, the report that the current uplink failure reason is caused by the terminal supporting dynamic power sharing capability actively stopping the uplink transmission of the auxiliary node link.

[0086] That is, the indication information includes: first indication information, where the first indication information is used to indicate that the auxiliary node link failure is caused by the terminal supporting dynamic power sharing actively stopping the uplink transmission of the auxiliary node link.

[0087] Optionally, the first indication information may be reported through secondary cell group (SCG) failure cause indication information or through other information. For example, a parameter may be carried in the SCG failure cause indication information, and when the parameter value is 10, it represents the first indication information.

[0088] In an embodiment of the present invention, when the sum of the transmission power of the terminal main node and the auxiliary node exceeds the threshold value "PEN-DC, tot_L" specified by the standard, the terminal needs to reduce the transmission power of the auxiliary node to ensure that the power sum is lower than the threshold value "PEN-DC, tot_L". If the power value that the auxiliary node link needs to reduce is lower than the threshold X_scale configured by the network, the auxiliary node link reduces the actual transmission power to the target transmission power. If the auxiliary node uplink and downlink fail due to the current auxiliary node link reducing the transmission power, the current uplink and downlink failure is reported as caused by the terminal supporting dynamic power sharing capability reducing the uplink transmission power of the auxiliary node.

[0089] That is, the indication information includes second indication information, and the second indication information is used to indicate that the auxiliary node link failure is caused by the terminal supporting dynamic power sharing reducing the transmission power of the auxiliary node link.

[0090] Optionally, the second indication information may be reported through SCG failure cause indication information or other information. For example, a parameter may be carried in the SCG failure cause indication information, and when the parameter value is 01, it represents the second indication information.

[0091] In an embodiment of the present invention, if a terminal supporting dynamic power sharing causes a wireless line failure due to the auxiliary node link stopping uplink transmission or reducing the transmission power of the auxiliary node link, the specific reason will be indicated in the reported failure reason, so that the network side can perform corresponding wireless resource configuration adjustments according to the reason, thereby ensuring the advantages of dual links, improving spectrum efficiency, and reducing operator operating costs.

[0092] Please refer to Figure 2 , Figure 2 This is a flow chart of a method for reporting a secondary node link failure according to another embodiment of the present invention, the method being applied to a terminal, comprising:

[0093] Step 21: reporting indication information indicating the cause of the auxiliary node link failure to the network side device, where the indication information is used to indicate that the auxiliary node link failure is caused by the terminal supporting dynamic power sharing.

[0094] Step 22: receiving the adjusted auxiliary node link configuration information sent by the network side device, where the adjusted auxiliary node link configuration information is obtained by the network side device adjusting the auxiliary node link configuration information according to the indication information.

[0095] In the embodiment of the present invention, optionally, the adjusting the auxiliary node link configuration information includes at least one of the following:

[0096] Adjusting the configuration position and / or configuration quantity of the radio resources of the secondary node;

[0097] Adjusting the configuration position and / or configuration quantity of the wireless resources of the master node;

[0098] Reduce the master node's transmit power;

[0099] The configuration position and / or configuration quantity of the radio resources of the primary node and the secondary node are jointly adjusted.

[0100] Optionally, the wireless resource is a resource block (RB).

[0101] Please refer to Figure 3 , Figure 3 This is a flow chart of a method for reporting a secondary node link failure according to another embodiment of the present invention, the method being applied to a terminal, comprising:

[0102] Step 31: reporting indication information indicating the cause of the auxiliary node link failure to the network side device, where the indication information is used to indicate that the auxiliary node link failure is caused by the terminal supporting dynamic power sharing.

[0103] Step 32: Perform wireless link measurement on the secondary node according to the secondary node link configuration information.

[0104] Step 33: The master node reports the wireless link measurement result of the secondary node, so that the network side device can determine whether to adjust the secondary node link configuration information according to the secondary node link measurement result.

[0105] In the embodiment of the present invention, the terminal performs radio link measurement on the secondary node according to the secondary node link configuration information, and reports the radio link measurement result, so that the network side can determine whether to adjust the secondary node link configuration information according to the secondary node link measurement result.

[0106] In the above embodiments of the present invention, optionally, the method further includes:

[0107] After the terminal stops uplink transmission of the auxiliary node link or the terminal reduces the transmission power of the auxiliary node link for a specified time threshold, no adjusted auxiliary node link configuration information is received, and a scheduling request (SR) is sent to request new wireless resources to establish the auxiliary node link;

[0108] or

[0109] If the uplink data to be sent changes, the scheduling request is sent to request new wireless resources to establish a secondary node link.

[0110] In the embodiment of the present invention, if the auxiliary node uplink fails, the network decides to keep the existing auxiliary node in the resident state, and the related technology does not explain when the terminal can perform a new round of SCG uplink data transmission. In the embodiment of the present invention, it is proposed that the terminal actively stops the uplink transmission of the auxiliary node link or the terminal reduces the transmission power of the auxiliary node link. If the network side does not send new auxiliary node link configuration information after a certain time threshold, the terminal sends SR, or when the amount of uplink data sent by the terminal changes, the terminal initiates SR and performs a new round of data transmission process.

[0111] Please refer to Figure 4 The embodiment of the present invention further provides a configuration method for secondary node link failure, which is applied to a network side device and includes:

[0112] Step 41: receiving indication information for indicating a cause of a secondary node link failure of a terminal, wherein the indication information is used to indicate that the secondary node link failure is caused by the terminal supporting dynamic power sharing;

[0113] Step 42: According to the indication information, adjust the auxiliary node link configuration information so that the maximum power backoff value and / or the additional maximum power backoff value of the network side device meets the first condition; wherein the adjustment of the auxiliary node link configuration information includes at least one of the following:

[0114] Adjusting the configuration position and / or configuration quantity of the radio resources of the secondary node;

[0115] Adjusting the configuration position and / or configuration quantity of the wireless resources of the master node;

[0116] Reduce the master node's transmit power;

[0117] The configuration position and / or configuration quantity of the radio resources of the primary node and the secondary node are jointly adjusted.

[0118] The first condition can ensure normal communication of the auxiliary node link. The first condition may be, for example: the maximum power backoff value and / or the additional maximum power backoff value is less than a preset value.

[0119] Step 43: Send the adjusted auxiliary node link configuration information to the terminal.

[0120] In an embodiment of the present invention, if the terminal causes a wireless line failure due to supporting dynamic power sharing, the reported failure cause indicates that it is caused by supporting power sharing, so that the network side can perform corresponding wireless resource configuration adjustments according to the cause, solve the auxiliary node link failure problem, quickly complete the auxiliary node uplink and downlink wireless link establishment work, reduce the main node network pressure, ensure the dual link advantage, improve spectrum efficiency, and reduce operator operating costs.

[0121] In an embodiment of the present invention, optionally, according to the MPR (maximum power backoff value) and / or A-MPR (additional maximum power backoff value) formula, the auxiliary node link configuration information is adjusted so that the maximum power backoff value and / or additional maximum power backoff value of the network side device meets the first condition.

[0122] Optionally, the wireless resource is a resource block (RB).

[0123] Optionally, the adjusting the auxiliary node link configuration information includes:

[0124] A first resource block is selected for the primary node and / or the secondary node, where the first resource block satisfies one of the following conditions:

[0125] The signal quality meets the second condition;

[0126] Located near the center of the channel;

[0127] The resource blocks of the secondary node and the primary node are located adjacently.

[0128] The signal quality meeting the second condition means selecting a wireless resource with better signal quality, and using the signal quality in exchange for making the MPR and / or A-MPR as small as possible.

[0129] In the embodiment of the present invention, optionally, the adjusted auxiliary node link configuration information is sent via downlink control information (DCI) or RRC information.

[0130] In the embodiment of the present invention, optionally, the adjusting the auxiliary node link configuration information includes at least one of the following:

[0131] (1) adjusting the configuration position and / or configuration quantity of the radio resources (RB) of the secondary node;

[0132] In an embodiment of the present invention, optionally, the configuration position and / or configuration quantity of the RB of the auxiliary node is adjusted, and the adjustment criterion is to make the maximum power backoff value and / or additional maximum power backoff value of the network side device meet the first condition. For example, the maximum power backoff value (MPR) of EN-DC (EUTRAN NR dual connection), NE-DC (NR-E-UTRA dual connection), NR-DC, LTE or NR is minimized as much as possible. For example, while ensuring the selection of RB resources with better signal quality, try to configure the RB to the center of the entire channel.

[0133] (2) adjusting the configuration position and / or configuration quantity of the wireless resources of the master node;

[0134] In an embodiment of the present invention, optionally, the configuration position and / or configuration quantity of the RB of the master node is adjusted, wherein the RB adjustment criterion makes the maximum power backoff value and / or additional maximum power backoff value of the network side device meet the first condition. For example, the MPR of EN-DC, NE-DC, NR-DC, NR or LTE is minimized as much as possible. For example, while ensuring the selection of RB resources with better signal quality, the RB is configured to the center of the entire channel as much as possible.

[0135] (3) Reduce the transmission power of the master node.

[0136] In an embodiment of the present invention, optionally, the transmit power of the master node is reduced, and the adjustment criterion is to make the maximum power backoff value and / or additional maximum power backoff value of the network side device meet the first condition. For example, the maximum power backoff value (MPR) of EN-DC (EUTRAN NR dual connectivity), NE-DC (NR-E-UTRA dual connectivity), NR-DC, LTE or NR is minimized.

[0137] (4) Jointly adjust the configuration position and / or configuration quantity of the wireless resources of the primary node and the secondary node.

[0138] In an embodiment of the present invention, optionally, the configuration position and / or configuration quantity of the radio resources of the primary node and the secondary node are jointly adjusted, and the adjustment criterion is to make the maximum power backoff value and / or additional maximum power backoff value of the network side device meet the first condition. For example, the maximum power backoff value (MPR) of EN-DC (EUTRAN NR dual connection), NE-DC (NR-E-UTRA dual connection), NR-DC, LTE or NR is minimized.

[0139] When the above four, three or two of them are combined, the RB adjustment criteria are similarly such that the MPR (maximum power fallback value) of EN-DC, NR-DC, NR or LTE is minimized. For example, for a terminal supporting NS_04 signal, the number and position of RB configuration of the main and auxiliary nodes can be appropriately and reasonably changed so that ① the frequency of harmonic, forward and reverse intermodulation products is higher than 2490.5MHz and falls as far as possible at a position where the SEM value is as high as possible, such as -13dBm / MHz instead of -25dBm / MHz, ② the RB of the main node is configured at a position with better signal quality and at the center of the channel, and ③ the RB positions of the auxiliary node and the main node are as close as possible. If there is a conflict between ①, ② and ③ above, the network side can decide the specific configuration plan by itself to ensure that the RB with better signal quality is selected while reducing the MPR value.

[0140] In an embodiment of the present invention, for uplink and downlink link failures caused by the reduction of transmission power of the auxiliary node of the dynamic power sharing terminal or the cessation of uplink transmission, the network side can solve the cause of the uplink and downlink wireless link failure of the auxiliary node by reducing the position and / or configuration quantity of the wireless resources of the auxiliary node, adjusting the configuration position and / or configuration quantity of the wireless resources of the main node, or the main and auxiliary nodes jointly coordinate the configuration position and / or configuration quantity of the wireless resources, and / or reduce the transmission power of the main node.

[0141] In an embodiment of the present invention, for uplink and downlink link failures caused by other reasons, the network side device can solve the problem of uplink and downlink wireless link failures of the auxiliary node by switching cells, updating the configuration location of wireless resources, and increasing the scheduling priority of the current terminal in the auxiliary node cell.

[0142] In the embodiment of the present invention, optionally, after receiving the indication information indicating the cause of the secondary node link failure of the terminal, the step further includes:

[0143] Stop sending the power increase indication information to the terminal.

[0146] If the auxiliary node link measurement result indicates that the current auxiliary node cell is the best cell among all the auxiliary node cells, adjusting the auxiliary node link configuration information according to the indication information;

[0147] If the auxiliary node link measurement result indicates that the current auxiliary node cell is not the best cell among all auxiliary node cells, the auxiliary node link is released or auxiliary node cell reselection is performed.
