Description

Information reporting and receiving method, terminal and network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, a terminal, and a network device for reporting and receiving information.

Background

A Conditional Handover (CHO) mechanism, that is, when a channel between a UE (User Equipment or terminal) and a serving cell suddenly becomes poor (especially in a high-frequency and high-speed scenario), the UE cannot normally complete a handover process. Therefore, the base station can configure the UE to trigger measurement report at a lower threshold, the source base station selects the target base station to perform switching request and confirmation according to the information reported by the user, the determined CHO list is configured to the user equipment in the CHO command, the higher threshold for triggering switching and the random access resource used by the UE in the target cell are carried, and once the switching threshold is met, the UE initiates a random access process to the target base station. As shown in figure 1 of the drawings, in which,

in the Dual Active Protocol Stack (DAPS) handover, after receiving RRC (radio resource control) information containing a handover command, the connection with the source base station is still maintained until the target base station is successfully accessed, and then the source cell is released.

Based on the existing CHO scheme, because a CHO list is configured at a lower threshold and the list updating instantaneity is not enough, a certain target cell meets the handover triggering condition after the user moves, and because the position of the user changes, the currently measured best cell is not a candidate target cell configured for the terminal by the previous source base station, and the terminal easily causes large interference to the neighboring cell or triggers fast handover after accessing the target cell. In the traditional CHO, because the source connection is unavailable when the UE executes the CHO, if the received CHO configuration is unavailable, the UE directly carries out reconstruction, and the problem of resource reservation waste or access incapability is caused.

If the CHO is combined with the DAPS HO, the terminal can still receive and transmit information through the source connection during handover, and further a series of problems can be generated, such as checking the availability of the CHO configuration, timely uploading of the end information and the recorded handover optimization information, and the like. In addition, when the target cell meets the CHO execution condition and the UE performs handover by itself, the source cell does not know when Data Forwarding (the CPU copies the output value content of one unit to the input value of another unit in one clock cycle) should be performed, which results in a large amount of waste of resources and a long interruption time for delayed Data Forwarding after successfully accessing the target cell compared to the current situation in which Data Forwarding is performed too early for all nodes after confirming candidate nodes.

In an alternative embodiment of the present invention, step 22 may include one of:

1) when the terminal is in a connection state, reporting the relevant information of the condition switching to network equipment;

2) the terminal reports the relevant information of the condition switching to the network equipment in the process of converting the non-connection state into the connection state;

3) and when the terminal is in an idle state or a non-activated state, reporting the relevant information of the condition switching to the network equipment.

In an optional embodiment of the present invention, reporting the information related to conditional handover to a network device includes:

and reporting the relevant information of the conditional switching to a network device through a Radio Link Failure (RLF) report or a predefined message.

In an optional embodiment of the present invention, reporting the information related to conditional handover to a network device includes one of the following:

1) reporting the relevant information of the condition switching to the network equipment according to the request of the network equipment;

2) the terminal actively reports the relevant information of the condition switching to network equipment;

3) and after the terminal reports the recorded information of the network equipment, reporting the recorded related information of the condition switching to the network equipment according to the request of the network equipment.

In an optional embodiment of the present invention, if the terminal performs conditional handover by using dual active protocol stacks or dual connectivity, step 22 may include: and reporting the relevant information of the conditional switch to the source cell through the connection of the source cell.

In an optional embodiment of the present invention, reporting the information related to conditional handover to a source cell through source cell connection includes: and through the connection of the source cell, carrying the relevant information of the condition switching in a feedback message ACK of a radio resource control RRC reconfiguration message or a predefined message, and reporting to the source cell.

In an optional embodiment of the present invention, if the terminal performs conditional handover by using a dual active protocol stack or dual connectivity, recording conditional handover related information measured when the terminal performs conditional handover, where the conditional handover related information includes:

Correspondingly, reporting the information related to the conditional handover to the source cell includes:

1) a configuration indicated by 1bit is not available;

2) the configuration of the at least one candidate target cell indicated by the multi-bit information is not available or applicable;

3) at least one configuration of the at least one candidate target cell indicated by the multi-bit information is not available or applicable.

In an optional embodiment of the present invention, if the configuration in the conditional handover related information is unavailable and the conditional handover is triggered to be executed, the terminal performs the connection reestablishment procedure by itself if the target cell configuration in the conditional handover related information is unavailable.

Optionally, reporting the inspection result to the source cell includes: the configuration of the target cell in the relevant information of the conditional switch is not available and the execution of the conditional switch is triggered, and the terminal stops the execution of the conditional switch and informs the source cell that the configuration in the relevant information of the conditional switch is not available through the source connection with the source cell.

1) informing the source cell through 1-bit information that the configuration in the conditional handover related information is unavailable;

2) informing the source cell through multi-bit information, wherein the conditional switching configuration of the target cell in the conditional switching related information is unavailable or applicable;

3) and informing the source cell by multi-bit information that at least one item of configuration of the target cell in the conditional handover related information is unavailable or applicable.

Specifically, if the UE utilizes a DAPS HO or dual connectivity capability, wherein the CHO and DAPS HO are selectable in the capability list and reported upon reporting of the capability. The information recorded by the source cell terminal may be reported in real time through the source cell connection still available, where the reported content may be in an RRC reconfiguration message ACK or in a newly defined message.

The terminal records the cell quality information and the beam quality information of the candidate target cell and the adjacent cell measured during the condition switching, and reports the cell quality information and the beam quality information to the network, so that the network side can be helped to configure a reasonable cell list for the condition switching and related optimization such as events and parameters for triggering the condition switching.

If the UE utilizes the capability of a DAPS HO or dual connectivity: the UE checks the availability of the CHO configuration given by the source cell if the configuration is not available and either CHO execution is not triggered or CHO execution is triggered, but not the target cell configuration. The UE records the check result and informs the source cell CHO configuration not available through the still available source connection. Wherein, the notification information may be: the 1bit information indicates that the configuration is not available; the multi-bit information indicates which specific candidate target cell-related configuration is not available or applicable; the multi-bit information indicates which configurations of which candidate target cells are not available or applicable.

If the CHO execution is triggered and the unavailable CHO configuration is related to the target cell, the UE executes the reconstruction by itself;

the UE stops the CHO execution and informs the source cell that the CHO configuration is not available through the source connection that is still available. Wherein, the notification information may be: the 1bit information indicates that the CHO configuration is not available; the multi-bit information indicates that the CHO configuration of the target cell is unavailable or applicable; the multi-bit information indicates which configurations of the target cell are not available or applicable.

After receiving the message that the CHO configuration of the UE is unavailable, the source cell can perform the following operations:

informing the UE to carry out reconstruction; specifically, the UE may be notified to perform the reconfiguration through an RRC reconfiguration message;

ignoring the CHO configuration: the UE can be informed to ignore all given CHO configurations or to ignore CHO configurations corresponding to one or more unavailable candidate target cells, and the UE continues to monitor the available CHO candidate cells and execute subsequent operations;

performing CHO configuration update: the source cell can be reconfigured according to the received indication, if the CHO execution condition Ax event which cannot be configured as the source cell configuration is known, the source cell updates the event by itself and sends the updated RRC reconfiguration message to the UE; if the unavailable configuration is known as the CHO configuration given by the candidate target cell, notifying that the configuration of the corresponding candidate target cell is unavailable, wherein the notification information may be: the 1bit information indicates that the configuration is not available or applicable; CHO configuration of the candidate target cell given by the candidate target cell.

The source cell may start a timer after sending the notification to the candidate target cell. The timing duration of the timer may be protocol-defined or configured by the base station. If the timer is overtime and no reply of the candidate target cell is received, the reconfiguration request is sent again once or more (the times can be specified by a protocol or matched by a base station), and if the reply is not continuously sent, the corresponding non-replied candidate target cell is deleted from the candidate list.

If the source cell receives the update information of the target cell, the source cell sends the updated RRC reconfiguration message to the UE;

and after receiving the notice that the configuration of the source cell is unavailable, the candidate target cell decides to update or not update the CHO configuration according to the received information. Optionally:

updating the CHO configuration: and sending the reconfigured configuration to the source cell.

Not updating the CHO configuration, optionally, the cell sends an indication that the target cell is not updated or is no longer a candidate target cell;

no operation is performed.

In the above embodiments of the present invention, since the source cell connection is not guaranteed, and the unavailable configuration is updated when the source cell connection is still available in the DAPS HO.

If the UE utilizes the DAPS HO or the dual connectivity capability, after satisfying the CHO execution condition or successfully accessing the target cell, the UE informs the source cell that the CHO has been executed through the source cell connection that is still available, and the message may include:

triggering CHO target cell related information;

information about cells in the CHO list;

and after receiving the executed CHO information transmitted by the UE through the still available source cell connection, the source base station forwards data to the target base station.

The embodiment of the invention helps the source base station to determine a more appropriate data forwarding time point, can reduce a large amount of waste of resources, can avoid longer interruption time, and can provide the time point for determining the target cell (avoid resource waste caused by all candidate cells, can also forward to a certain extent, reduce interruption time) or after successfully accessing the target cell (provide maximum reliability, avoid resource waste).

In an optional embodiment of the present invention, the method for reporting information may further include:

Optionally, the information reporting method further includes:

information related to the target cell that triggered the conditional handover;

information about the cells in the conditional handover list.

In the above embodiment of the present invention, the cell related information includes at least one of the following:

cell ID (e.g., at least one of PCI, GCI, ARFCN, and cell index);

cell quality (e.g., at least one of RSRP, RSRQ, SINR);

UE measures ID of beam of the cell: SSB or CSI-RS;

quality of the beam: quality of the SSB or CSI-RS (e.g., at least one of RSRP, RSRQ, SINR);

identification of whether a cell is in the CHO list.

The CHO configuration described above may include: CHO executes conditional Ax events (e.g., A3 or a5 events);

and the CHO configuration given by the candidate target cell, such as random access resources and the like. The situation where the configuration is not available includes, but is not limited to, exceeding the terminal capability, such as the number of times the terminal cannot recognize the partial RACH (random access) resource, the bandwidth location where the terminal does not support the RO configuration, or the BWP (bandwidth partial) of the candidate target cell configuration exceeds the terminal capability.

The terminal records the cell quality, beam quality and other relevant information of the candidate target cell and the adjacent cell measured during condition switching and reports the information to the network. The recorded or reported quality and other related information can help the network side to configure a reasonable cell list for conditional handover and related optimization of events, parameters and the like for triggering the conditional handover. For example, the recorded optimal cell which is not in the CHO list is allocated to the user at the time of initial configuration, thereby effectively avoiding fast handover and handover failure.

The different effects of binding of DAPS HO and CHO are further illustrated, in particular: in CHO, UE measurement results meet CHO execution conditions and then switch automatically, and informs a source cell of a target cell through DAPS/dual-connection available source connection, and the source cell can select time for starting data forwarding according to the information. And unavailable CHO configurations can be updated with better quality source connections.

The following describes a specific implementation process of the above method with reference to a specific embodiment:

example 1: when the UE performs switching, the configuration of the candidate cell which is not a target is found to exceed the capability of the UE;

when UE executes switching, the CHO configuration given by some non-target candidate target cell in RRC reconfiguration signaling given by a source cell is found to exceed the capability of the UE;

the UE continues to execute the switching, and sends information to the source cell through the original connection which is still available, and informs that certain configuration given by a certain candidate target cell exceeds the capability of the UE;

after receiving an unavailable indication given by the UE, the source cell sends information to a candidate target cell with a problem and tells the candidate target cell which specific configuration exceeds the capability of the UE;

after receiving the message of the source cell, the candidate target cell gives the CHO configuration conforming to the UE capability again and returns the CHO configuration to the source cell;

the source cell transmits the received configuration of the candidate target cell to the UE;

the UE stores all available CHO configurations.

Example 2: when UE executes switching, the candidate cell configuration of a target is found to exceed the capability of the UE;

when UE executes switching, the CHO configuration given by the target cell exceeds the capability of the UE in the RRC reconfiguration signaling given by the source cell;

the UE stops executing the switching, and sends information to the source cell through the original connection which is still available, and informs that certain configurations given by the target cell exceed the capability of the UE;

after receiving an unavailable indication given by the UE, the source cell sends information to the target cell to tell the target cell which specific configuration exceeds the capability of the UE;

after receiving the message of the source cell, the target cell gives the CHO configuration conforming to the UE capability again and returns the CHO configuration to the source cell;

the source cell transmits the received configuration of the target cell to the UE;

the UE stores all available CHO configurations, continuously monitors the CHO triggering conditions of each candidate target cell, and executes subsequent processes.

Example 3: when the switching is not triggered, the UE informs a source cell that the configuration of a certain candidate target cell in the multi-candidate target cell is unavailable;

when the switching is not triggered, the UE finds that the CHO configuration given by a certain candidate target cell is unavailable in the RRC reconfiguration signaling given by the source cell;

UE sends information to source cell to inform some candidate target cell that CHO configuration is not available;

after receiving an unavailable instruction given by UE, a source cell sends information to a candidate target cell with a problem and tells that the configuration is unavailable;

after receiving the message of the source cell, the candidate target cell gives CHO configuration for the UE again and returns the CHO configuration to the source cell;

the UE stores all available CHO configurations and continuously monitors the CHO trigger conditions for each candidate target cell.

Example 4: when the switching is not triggered, the UE informs the source cell that the configuration of a certain candidate target cell in the multi-candidate target cell is unavailable

after receiving the message of the source cell, the candidate target cell decides not to do the CHO candidate target cell and does not reply;

after the source cell does not receive the reply of the candidate target cell for a certain time, the source cell orders the UE to release the CHO configuration of the candidate target cell;

and the UE releases the unavailable CHO configuration of the candidate target cell after receiving the command and continuously monitors the CHO triggering conditions of other candidate target cells.

Example 5: CHO configuration unavailability of all candidate cells received by the UE

When the switching is not triggered, the UE finds that the CHO configuration of partial candidate cells in RRC reconfiguration signaling given by the source cell is unavailable;

UE starts a timer and continuously receives the reconfiguration message given by the source cell;

after the timer expires, no new CHO configuration is received, which is available, the UE triggers a re-establishment.

Example 6: UE finds out that the received CHO configuration of the target cell is unavailable when triggering handover

UE finds that the CHO configuration of the target cell in the RRC reconfiguration signaling given by the source cell is unavailable;

the UE triggers the re-establishment.

In the above embodiment of the present invention, the terminal records the cell quality, beam quality, and other relevant information of the candidate target cell and the neighboring cell measured during the condition switching, and reports the information to the network. The recorded or reported quality and other related information can help the network side to configure a reasonable cell list for conditional handover and related optimization of events, parameters and the like for triggering the conditional handover. The method avoids the waste of a large amount of resources and the long interruption time caused by the forwarding of delay data after the target cell is successfully accessed.
