Detailed Description

So that the manner in which the features and aspects of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.

For the Data replication transmission mechanism under CA defined in 5G NR, the related protocol structure is as shown in fig. 1, after the PDCP layer generates PDCP PDUs based on the PDCP Service Data Units (SDUs) received by the higher protocol layer, the PDCP PDUs are replicated and the source PDCP PDUs and the replicated PDCP PDUs are transmitted to two R L C entities, e.g., R L C Entity a and R L C Entity b in fig. 1, respectively, and then the PDCP PDUs transmitted by different R L C entities are mapped onto different Physical layer carriers, e.g., Physical Carrier 1 and Physical Carrier 2, respectively, by a single MAC Entity for transmission, so as to improve the reliability of Data transmission by using the frequency diversity gain of the carriers.

Based on the protocol structure shown in fig. 1 and a data replication transmission mechanism under CA, it can be known that each R L C entity corresponds to one logical channel, and each logical channel may be configured to correspond to one or a group of cells, so that the configured cells or cell groups corresponding to the two logical channels are different, however, in the current discussion of the third Generation Partnership Project (3GPP, 3rd Generation Partnership Project), for the R L C entity of the UE, if all the configured cells or cell groups corresponding to the logical channels are secondary cells, when a certain R L C SDU of AM R L C is retransmitted up to the maximum retransmission number, that is, when R L C fails, it may only need to report to the network side without triggering RRC re-establishment, and the network side determines how to perform parameter reconfiguration, so as to reduce the occurrence of the phenomenon of service interruption of the UE due to RRC re-establishment.

In order to solve the problem of how to report to the network side in the R L C failure state, the following embodiments are proposed in the present application based on the above description.

Example one

Referring to fig. 2, it shows a method for information transmission provided in an embodiment of the present invention, which may be applied to a user equipment UE side, and the method includes:

s201, detecting an event occurring in an R L C entity based on a preset detection strategy;

s202, in response to the detection of a preset secondary cell radio link failure R L F event, sending report information generated based on the secondary cell R L F event through Radio Resource Control (RRC) signaling.

It should be noted that the reported information may be used by the network side to determine whether to perform reconfiguration.

Through the technical scheme shown in fig. 2, it can be seen that in the technical scheme shown in fig. 2, after the UE detects the R L F event of the secondary cell, the UE sends the reporting information to the network side by using the RRC signaling, so that the network side can determine whether to perform reconfiguration according to the reporting information, thereby avoiding that the UE directly triggers the RRC reestablishment process due to the R L F event, and reducing the phenomenon of service interruption caused by the RRC reestablishment process.

For the technical solution shown in fig. 2, in a possible implementation manner, the detecting an event occurring in the R L C entity based on a preset detection policy includes:

determining a target R L C entity in two R L C entities for PDCP duplicate transmission, wherein all cells or cell groups configured by logical channels corresponding to the target R L C entity are secondary cells;

detecting the retransmission times of each R L C SDU or R L C PDU of the target R L C entity.

For the above implementation, it should be noted that, in the process of performing data duplication transmission under CA, the UE may detect an event occurring in the R L C entity, for example, detect the communication quality of a cell or a cell group configured by a logical channel corresponding to the R L C entity, or detect the data transmission amount of a logical channel corresponding to the R L C entity, and for the AM R L C entity, the UE may also detect the number of retransmissions of a certain R L C SDU or R L C PDU of the AM R L C entity, and the like, for the AM R L C entity, the UE may detect all possible events occurring on the R L C entity, and in this embodiment, for a secondary cell radio link failure R L F event, the UE may be more interested in the number of retransmissions of each R L C SDU or R L C PDU of the target R L C entity, and therefore, specifically, for each R L C SDU or R L C SDU of the target R L C entity, or R L C entity, the number of retransmissions may reach a preset threshold, and it may be considered that the UE may detect the number of retransmissions of a secondary cell failure events based on the preset threshold R638C PDU, and therefore, when the number of retransmissions reaches the preset threshold of retransmissions is detected events, the preset threshold is considered that the secondary cell failure event, the detection is detected event, the threshold is equal to be the threshold, and the threshold is equal to be equal to the threshold, and the threshold:

and when the retransmission times of any R L C SDU or R L C PDU of the target R L C entity reach the preset maximum retransmission times, determining that the secondary cell R L F event is detected.

It can be understood that, after the event of the secondary cell R L F is detected, to avoid the occurrence of a service interruption phenomenon caused by the UE directly initiating an RRC reestablishment procedure, reporting is usually performed to the network side, and the network side determines whether to perform RRC reconfiguration according to the reporting.

Based on the above comprehensiveness, for the technical solution shown in fig. 2, in a possible implementation manner, the sending, by using a radio resource control RRC signaling, reporting information generated based on a radio link failure R L F event in response to detecting a preset secondary cell radio link failure R L F event includes:

when the secondary cell R L F event is detected, triggering to send first reporting information through RRC signaling, wherein the first reporting information is generated based on the detected secondary cell R L F event.

For the above implementation, it should be noted that the secondary cell R L F event may be used as a trigger condition for sending the first reporting information, and after the first reporting information is sent, whether to perform RRC reconfiguration for the secondary cell R L F event is determined by the network side.

And if the preset timer is in a non-timing state, triggering to send the first report information through an RRC (radio resource control) signaling, and starting the timer.

In the timer process, there may be a plurality of situations occurring at the UE side, and therefore, for the situations that may additionally occur in the timer process, the following preferred scheme is adopted in the present embodiment to perform processing.

Preferably, in the timer process, sending the first reporting information through RRC signaling is not triggered, and the secondary cell R L F event detected again is set to a waiting state.

In view of the above preferred embodiments, the method may further include:

and when the timer is overtime, if an auxiliary cell R L F event in a waiting state exists, sending second reporting information through a Radio Resource Control (RRC) signaling, wherein the second reporting information is generated based on the auxiliary cell R L F event in an undetermined state.

It can be understood that, during the timer timing process, the secondary cell R L F event may be still detected, but at this time, the network side does not have an indication of RRC reconfiguration, and therefore, in order to reduce the processing load of the network side, all the secondary cell R L F events detected during the timer timing process may be reported to the network side after the timer expires.

Preferably, in the timer counting process, if the RRC reconfiguration signaling is received, the timer is stopped.

It can be understood that, in the timer timing process, if the RRC reconfiguration signaling fed back by the network side based on the first reported information is received, the RRC reconfiguration process is performed on the logical channel corresponding to the target R L C entity, so that the timer timing is stopped, and the timer is turned to an untimed state, so that after the RRC reconfiguration process is completed, the event occurring in the R L C entity is detected again according to S201.

Based on this, after the timer stops timing, the above preferred example may further include canceling all the set standby-state secondary cell R L F events in the timing process of the timer before the timer stops timing, so that it is not necessary to report second report information generated for the standby-state secondary cell R L F event to the network side, and the network side also accordingly does not need to re-determine whether to perform RRC reconfiguration according to the second report information.

The specific content refers to the reconfiguration signaling that includes processing on the secondary cell R L F, such as related signaling that includes a reconfiguration R L C entity.

The foregoing two possible implementations describe the specific implementation process of the scheme shown in fig. 2 in detail, but since the network side determines whether to reconfigure based on the reporting information, the reporting information carried in the RRC signaling needs to enable the network to measure and acquire the description information related to the secondary cell R L F event.

For the implementation manner, specifically, the report information includes identification information that the target R L C entity has an association relationship and/or cell quality information corresponding to the target R L C entity.

The identification information of the target R L C entity having the association relationship may specifically include at least one of a logical channel identifier, a cell group identifier, a bearer identifier, and a cell identifier corresponding to the target R L C entity, where the target R L C entity is located.

As for the cell quality information corresponding to the target R L C entity, at least one of the following items is specifically included:

the quality information of the current serving cell and the quality information of the non-serving cell with the best quality on the frequency to which the cell corresponding to the target R L C entity belongs;

the quality information of the current serving cell and the non-serving cell quality information with the best quality on the frequency of other serving cells except the cell corresponding to the target R L C entity;

the best quality cell on other frequencies than the frequencies to which all serving cells belong.

It should be noted that, in the foregoing implementation manner, the cell corresponding to the target R L C entity includes an active cell corresponding to the target R L C entity, or an active cell and an inactive cell corresponding to the target R L C entity.

It can be understood that, the implementation manner of the aforementioned reporting information can describe the secondary cell R L F event from multiple aspects, so that the network side can accurately determine whether to perform reconfiguration according to the reporting information.

This embodiment provides a method for transmitting information, in which after detecting an R L F event in an auxiliary cell, a UE sends reporting information to a network side by using an RRC signaling, so that the network side can determine whether to perform reconfiguration according to the reporting information, thereby avoiding a direct triggering of an RRC reestablishment process by the UE due to the R L F event, and reducing a service interruption phenomenon caused by the RRC reestablishment process.
