Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This application claims priority to Chinese Patent Application No. 202210306878.2, filed in China on March 25, 2022, the entire contents of which are incorporated herein by reference. The present disclosure relates to the technical field of communications, and in particular to an information transmission method, an information reception method, an apparatus, and a storage medium. [Background technology]

[0002] In a dual connection scenario, if a user equipment (UE) detects that a radio link failure (RLF) occurs in a master cell group (MCG) and the UE is configured with a mechanism for fast MCG connection recovery, the UE can suspend transmission of all radio bearers of the MCG and transmit MCG error information, such as measurement results of MCG and / or SCG cells measured by the UE, to a master node (MN) via a secondary cell group (SCG). Within a certain preset time length (T316), the UE may receive feedback messages such as Radio Resource Control (RRC) reconfiguration, handover, RRC release, etc. transmitted from the MN via the SCG and perform subsequent operations, while if the UE does not receive any of the above messages transmitted from the MN after the preset time length has elapsed, the UE initiates a re-establishment procedure. The fast MCG connection recovery mechanism can help the UE recover the connection with the MCG as quickly as possible, thereby avoiding the UE initiating re-establishment and entering an idle state, which would affect the UE's service experience.

[0003] A drawback of the related art is that due to parameter configuration problems, the MCG connection restoration mechanism cannot restore the connection between the UE and the MCG and / or SCG as quickly as possible. Summary of the Invention [Problem to be solved by the invention]

[0060] The inventors noticed the following during the invention. If an MCG Failure is detected by the UE during a Conditional Primary-Secondary Cell (PSCell) Change (CPC), the UE shall directly perform the re-establishment procedure. When the Secondary Node (SN) or SCG or PSCell is in deactivation state (the "SCG deactivation" in the following description refers to these three cases), the network side may also configure the UE to perform fast MCG connection recovery upon MCG failure. Compared with normal dual connection, when the SCG is deactivated, the UE needs to activate the SCG first to enable reporting of MCG error information via the SN. In order to detect potential MCG failure, SCG deactivation state earlier, different parameters such as T310, N311, T316, etc. may be used. After the UE receives an MN reconfiguration or handover or RRC release command, an MCG failure may be detected still soon (e.g., within a certain preset time) after the reconfiguration becomes effective (e.g., a longer T310, a smaller N311 is configured, etc.), or a new MCG failure may occur soon after the cell is changed according to the handover command, or an RRC connection with the target cell may not be established, or the UE may detect that the signal quality of the MCG has recovered to a relatively good level after the UE receives an RRC release command, or the UE has not received any information from the network side at the expiration of T316 (the cause may be that T316 is set too short, or the MN is configured too late, or the signal quality of the SN or SCG or PSCell is poor and the transmission is not successful), and a re-establishment procedure is initiated by the UE, which may result in a temporary loss of the RRC connection between the UE and the network side, affecting data transmission and the UE's service experience. If an MCG Failure occurs when the SCG is in a deactivated state, it may be because the UE has activated the SCG for too long, and at the expiration of T316, no network-side feedback information has been received by the UE. If the UE can report relevant information when an MCG failure occurs, such as the configurations of T310, N311, and T316, information that the SCG is in a deactivated state, the time it takes to activate the SCG, information that the UE has received RRC reconfiguration information, the target cell for handover, and measurement results, it can help the network side analyze whether the above configured parameters are appropriate and perform corresponding optimization.

[0061] Based on this, in a technical aspect according to an embodiment of the present disclosure, a mechanism is proposed for a UE to report related information of MCG failure, which can assist the network side in configuring appropriate parameters, assist the UE in recovering the connection between the MCG and / or SCG as quickly as possible, and improve user experience.

[0062] Hereinafter, specific embodiments of the present disclosure will be described with reference to the drawings.

[0063] In the description, the implementation of the UE side and the base station side will be described first, and then an example of the implementation of the two in conjunction will be given to better understand the implementation of the aspects listed in the embodiments of the present disclosure. This explanation does not mean that the two must be implemented in conjunction with each other or independently, and in fact, when the UE and the base station are implemented separately, the problems of the UE side and the base station side are solved, while when the two are used in combination, a better technical effect can be obtained.

[0064] FIG. 1 is a schematic diagram of the implementation flow of the UE side information transmission method. As shown in the figure, The method may include step 101, in which the UE reports first information, which is related information of fast master cell group link recovery (Fast MCG Link Recovery).

[0065] FIG. 2 is a schematic diagram of the implementation flow of the information receiving method on the base station side. As shown in the figure, Step 201: a base station receives first information reported by a UE, the first information being related information of a fast master cell group connection recovery; The method may further include step 202, in which the base station configures fast master cell group connection restoration according to the first information.

[0066] In an embodiment, the first information is: The information may be obtained in one or a combination of the following ways: recorded by the UE, configured by network management to record the UE, configured by the TCE to record the UE, or configured by the base station to record the UE.

[0067] Specifically, the information may be recorded by the UE autonomously, or may be configured to be recorded and reported by the UE by a network management or a trace collection entity (TCE) or a base station.

[0068] In an embodiment, the first information is: This is reported when the UE is in a connected state, when the UE is transitioning to a connected state, when the UE sends an RRC re-establishment request message, or when the UE sends a radio link failure report.

[0069] Specifically, the UE reports the information when in a connected state or in transition to a connected state, or in an RRC re-establishment request message or a radio link failure report.

[0070] In implementation, the first information is requested and reported by the network side, or spontaneously reported by the UE, or requested and reported by the network side after the UE informs the network side that it has relevant information.

[0071] Specifically, the report states: It may be requested by the network side, it may be reported spontaneously by the UE, or it may be requested and sent by the network side after the UE has notified the network side that it has relevant information.

[0072] In an embodiment, the first information is: T316 configured by the network side, Radio link failure (RLF) detection related parameters used when a master cell group failure (MCG failure) is detected; The time lag between when the MCG failure information is sent and when the feedback information on the network side is received, and The length of time that T316 has run when the network feedback is received after sending the MCG failure information, and The percentage or percentage that T316 is running when network side feedback is received after sending MCG failure information; and Information on whether network side feedback was received before T316 expired; and Information on whether network side feedback was received when T316 expired; and Feedback information received before T316 expires; and feedback information received when T316 expires; and Secondary Cell Group (SCG) status information; Information whether the UE is performing a conditional primary / secondary cell change (CPC) procedure; and Information whether the UE is performing a conditional primary and secondary cell addition (CPA) procedure; Information on whether the UE has triggered the CPC; and Information on whether the UE has triggered CPA; and If a re-establishment or handover has occurred, an indication that the UE has experienced a fast master cell group link recovery (MCG link recovery); and If a handover command is received after the MCG failure information is sent, measurement information of the serving cell, neighboring cells, and target cell measured before or at the time of the handover; reconfigured parameters if a reconfiguration command is received after the transmission of the MCG failure information; If an RRC release command is received after sending MCG failure information, the measurement result of the master node MN or MCG or primary cell (Primary Cell, PCell), if an RRC release command is received after sending the MCG failure information, or an indication that the measurement result has exceeded a preset threshold.

[0073] Hereinafter, the reporting of information related to Fast MCG Failure recovery by the UE will be specifically described as A) to K). A) T316 configured by the network side (i.e., the maximum time length of T316 that starts after the transmission of MCG Failure information), which may be expressed as a time length or in a bit-indicated manner. For example, 10 values ​​can be configured for T316, with 0000 representing the first configuration, B) RLF detection-related parameters used when MCG failure was detected, such as one or more of T310, N311, or the maximum number of retransmissions of the Radio Link Control (RLC) protocol (expressed in the same manner as T316); C) The time difference between sending the MCG failure information and receiving the feedback information from the network side, or the length of T316 running when the feedback from the network side is received, or the percentage or percentage already running; D) Information on whether network side feedback was received before or when T316 expired; E) Feedback information received before or when T316 expires, such as RRC reconfiguration, or handover, or RRC release; F) Status information of the SCG, such as deactivation or whether to deactivate it; G) UE is CPC or condition TIFF2025510263000002.tif16166 Information on whether the Conditional PSCell Addition (CPA) procedure is being performed or whether CPC or CPA has been triggered. H) When re-establishment or handover occurs, indication information that there has been a fast MCG link recovery in related report information such as re-establishment or handover success or RLF report, which is an indication to inform the network side that a fast MCG link recovery has occurred in the UE; I) When a handover command is received after the transmission of MCG failure information, the measurement information of the serving cell, neighboring cell, and target cell measured before or during the handover; J) If a reconfiguration command is received after sending MCG failure information, this is information on which parameters have been reconfigured, for example new T310, T316, or optionally, information that the values ​​of these parameters have been reconfigured; K) If an RRC release command is received after sending MCG failure information, this is a measurement result of the MN or MCG or primary cell (PCell), or an indication that the measurement result has exceeded a preset threshold.

[0074] After obtaining the data information reported by the terminal, the network side (source MCG) can optimize the relevant configuration of the corresponding high-speed master cell group connection recovery in combination with other information such as RLF report, UE location, measurement result, etc. Hereinafter, the implementation of configuring high-speed master cell group connection recovery according to the first information will be described as 1) to 7).

[0075] 1) If T316 expires and no feedback information from the network side has been received, and the UE has performed re-establishment, then configure T316 to be longer if it is determined that the UE cannot wait for the feedback from the network side because T316 is configured too short according to the T316 configured by the network side, information on whether feedback from the network side has been received before T316 expires, information on whether feedback from the network side has been received when T316 expires, indication information for informing the network side that fast MCG link recovery has occurred in the case of re-establishment or handover, and the measurement results of the UE. Specifically, if T316 has expired and the feedback information from the network side has not yet been received and the UE has performed re-establishment, then according to the above-mentioned information A, D, H and the measurement result information of the UE, the network side will judge whether the UE could not wait for the feedback from the network side because T316 was configured too short (especially when the measurement result of the MN or MCG or PCell is not bad), and if so, the base station will consider configuring T316 to be longer subsequently.

[0076] 2) if T316 expires and no network feedback information has been received and the UE has performed re-establishment, then when it is determined according to the SCG status information that the SCG is in a deactivated state at that time, configure T316 to be longer so that the UE will not perform re-establishment too early; and / or If T316 expires and no network side feedback information is received, and the UE performs re-establishment, configure the parameters corresponding to the UE's detection of MCG failure to be shorter according to the information in the RLF detection-related parameters used when the MCG failure is detected, so that the potential RLF can be detected by the UE earlier. Specifically, if T316 has expired and the network side feedback information has not yet been received and the UE has performed re-establishment, according to the information in information F, if the SCG is in a deactivated state at this time, it will take some time for the SCG to recover to activation, so the network side can subsequently consider configuring T316 to be longer so that the re-establishment is not performed too early by the UE, and / or configuring the parameters corresponding to the UE's detection of MCG failure, such as T310, N311, or the maximum RLC retransmission count, to be shorter so that the UE can detect a potential RLF earlier according to the information in information B.

[0077] 3) According to the time difference between when the MCG failure information is sent and when the network side feedback information is received, the length of T316 running from when the MCG failure information is sent to when the network side feedback is received, the ratio or percentage of T316 running when the network side feedback is received after the MCG failure information is sent, the UE measurement result, and the length of T316 configured by the network side, configure a longer T316 if it is determined that the running length of T316 is within a predetermined time until expiration when the network side feedback is received, or configure a shorter T316 if it is determined that the running length of T316 is longer than the predetermined time until expiration when the network side feedback is received. Specifically, according to information C (the running length of T316 when the network side feedback is received), the UE's measurement result, and information A (the configured length of T316), the network side can determine whether to configure a longer T316 (when the running length of T316 when the network side feedback is received is very long and close to expiration) or a shorter T316 (when the running length of T316 when the network side feedback is received is very short and still long until expiration) as necessary.

[0078] 4) If an MCG failure occurs during the CPC procedure, configure CPC early according to information on whether the UE is performing a CPC procedure, information on whether the UE is performing a CPA procedure, information on whether the UE has triggered CPC, information on whether the UE has triggered CPA, and, in the event of re-establishment or handover, instruction information that informs the network side that fast MCG link recovery has occurred in the UE. Specifically, according to the information G and H, the network side can determine whether an MCG failure occurs in the CPC procedure, and if so, it means that the timing of the CPC configuration is too late, and the CPC needs to be configured earlier.

[0079] 5) When re-establishment or handover occurs, if a handover command is received after the UE receives indication information informing the network side that fast MCG link recovery has occurred and the MCG failure information is sent, determine whether the handover configuration information is valid according to the measurement information of the serving cell, neighboring cell, and target cell measured before the handover is initiated or at the time of the handover. Specifically, according to the information H and I, the network side can judge whether the configuration information of the handover is valid, such as whether the target frequency point of the handover, the selection of the cell is valid, and so on.

[0080] 6) When re-establishment or handover occurs, determine whether the newly configured parameters are valid according to the indication information informing the network side that fast MCG link recovery has occurred in the UE and the reconfigured parameters when a reconfiguration command is received after the MCG failure information is sent, depending on whether RLF or re-establishment subsequently occurs in the UE. Specifically, according to the information H and J, the network side can determine whether the configured new parameters are valid according to whether the UE subsequently experiences a situation such as RLF or re-establishment, for example, the UE experiences an RLF of MCG after the longer T310 and / or the longer T316 are reconfigured.

[0081] 7) When re-establishment or handover occurs, if a handover command is received after the UE receives indication information informing the network side that fast MCG link recovery has occurred and the MCG failure information is sent, determine whether an RRC release command is appropriate according to the measurement information of the serving cell, neighboring cell, and target cell measured before the handover is initiated or at the time of the handover.

[0082] Specifically, according to the information H and I, the network side can judge whether the RRC release command is appropriate, for example, if the MN or MCG or PCell quality measured by the UE is not bad (for example, if the measurement result exceeds a preset threshold), it means that the link of the MCG is restored, and the MCG should not be released, and T310, N311, or the maximum number of RLC retransmissions is configured.

[0083] Based on the same inventive concept, the embodiments of the present disclosure further provide a base station, a user equipment, and a computer-readable storage medium, and since the principles of solving the problems of these equipment are similar to the information receiving method and the information transmitting method, the implementation of these equipment can refer to the implementation of the method, and the overlapping parts will not be repeated.
