Description

Receiving and configuring method, equipment and medium

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a receiving method, a configuration method, a device, and a medium.

Background

The CHO (Conditional handover Over) means that a network configures a plurality of candidate cells for a terminal, and the terminal autonomously determines a target cell to be handed Over according to the comparison between the channel quality of different cells and an RSRP (Reference Signal Received Power) threshold, and the handover does not require a source base station to indicate the target cell to be handed Over by signaling. The CHO is a mechanism for enhancing robustness of a handover process, and compared with a conventional handover, the conditional handover can complete the handover process more quickly, so as to avoid a problem that the UE cannot complete the handover normally when a channel between the UE (User Equipment) and a serving cell is suddenly degraded (especially when the UE moves at a high frequency or a terminal moves at a high speed).

The base station can configure the UE to trigger measurement report at a lower threshold, the source base station selects a target base station to perform switching request and confirmation according to information reported by the user, a CHO command is configured to the UE through an RRC (Radio Resource Control) reconfiguration message, a determined CHO list is configured to the user in the CHO command, the CHO list carries a higher threshold for triggering switching, the UE can also carry random access resources used by the UE in a target cell, and once the switching threshold is met, the UE initiates a random access process to the target base station.

The prior art has the disadvantage that the signaling overhead is large because the network performs the related configuration of Conditional Handover (CHO) for each UE through RRC reconfiguration message.

Detailed Description

The inventor notices in the process of invention that:

in the prior art, since the network performs related configuration of Conditional Handover (CHO) for each UE through RRC reconfiguration message, in some specific cases, the overhead can be reduced, for example: in a high-speed rail and other scenes, generally, the UEs in one car are switched simultaneously, and since the high-speed rail line is relatively fixed, and the candidate target cells for switching are generally the same, for this scene, the related configuration of CHO can be performed in a grouping manner, and the parameters common to the UEs in the group are issued in a common manner, which can effectively reduce signaling overhead.

Based on this, the embodiment of the invention provides a conditional switching configuration scheme and a switching scheme.

The following describes embodiments of the present invention with reference to the drawings.

In the process of description, the implementation of the terminal and the network side will be described separately, and then an example of the implementation of the terminal and the network side in cooperation will be given to better understand the implementation of the scheme given in the embodiment of the present invention. Such an explanation does not mean that the two must be implemented in cooperation or separately, and actually, when the terminal and the network side are implemented separately, each of them solves the problem of the own side, and when the two are used in combination, a better technical effect is obtained.

Fig. 1 is a schematic flow chart of an implementation process of a configuration method on a network side, as shown in the figure, the implementation process may include:

step 101, the network side issues first information to the group of terminals, wherein the first information includes one or a combination of the following information:

Specifically, a plurality of first information may be configured to correspond to different terminals and/or terminal groups, and further, a corresponding/mapping relationship between the first information and the terminals and/or the terminal groups may be given.

Fig. 2 is a schematic flow chart of an implementation of a receiving method at a terminal side, as shown in the figure, the receiving method may include:

step 201, a terminal receives first information, wherein the first information includes one or a combination of the following information: measuring and reporting trigger condition information, switching execution condition information, candidate cell information, cell information of a removed candidate cell and random access information.

Further, the method can also comprise the following steps:

step 202, the terminal performs switching according to the first information.

This is because the first information may be used in a conditional switching scenario or other switching scenarios, and the following description mainly takes a switching scenario as an example.

In an implementation, the first information is applied to one terminal or at least 2 terminals.

The following description will be mainly divided into three parts, which are: the content of the first information of the grouping configuration, the network issues the switching or conditional switching command of the grouping configuration, and the terminal acts. However, it should be noted that the division into three parts is only for convenience of explanation, and the explanation of the scheme and the technical features is not related to the division into three parts, and the scheme is specifically described below.

Firstly, grouping the contents of the configured first information.

In an implementation, the first information may include one or a combination of the following information:

Specifically, the network issues a first message, which may be applied to a group of UEs, where the first message includes at least one of the following:

1. specifically, the measurement reporting trigger condition refers to a trigger condition for reporting a measurement result to a network side, and includes at least one of the following: measuring quantity and measuring and reporting a trigger event. A plurality of measurement reporting trigger conditions may be configured, for example, different measurement reporting trigger conditions may be configured for a condition switching scenario and a normal switching (unconditional switching) scenario;

2. the handover execution condition information may include a first channel Quality threshold, a second channel Quality threshold (e.g. rsrp, RSRQ (Reference Signal Received Quality), SINR (Signal to Interference plus Noise Ratio)).

The first channel quality threshold is used to determine whether to start conditional handover, specifically, when the channel quality of the serving cell is lower than the first channel quality threshold, the terminal starts conditional handover related operations, for example, starts measurement of handover candidate cells configured by multiple networks; when the channel quality of the serving cell is higher than the first channel quality threshold, the terminal does not need to start the relevant operation of conditional switch.

The conditional switch is initiated when the channel quality of the first cell is below and/or equal to a first channel quality threshold. The first cell may be a serving cell.

The second cell may be a target cell or a candidate cell for handover when the channel quality of the second cell is above and/or equal to a second channel quality threshold.

The second channel quality threshold is used to determine the target cell. The second channel quality threshold is used for the terminal to autonomously determine a target cell for handover, and specifically, in the candidate cells, a cell whose channel quality satisfies the second channel quality threshold becomes a target cell for handover.

The candidate cells may be configured with the same second channel quality threshold, or different candidate cells may be configured with different second channel quality thresholds, and regarding the latter, since the second channel quality thresholds of different candidate cells are different, the target cell sequence in continuous multiple times of conditional handovers may be determined.

That is, the handover execution condition information includes: the method comprises the steps of determining whether to start conditional switching or not and determining a target cell by using a first channel quality threshold and/or a second channel quality threshold.

3. The candidate Cell information is, specifically, the candidate Cell information refers to candidate Cell information of a target Cell to which the terminal performs handover, such as a Cell identity PCI (Physical Cell Identifier), which includes a plurality of candidate Cell information for conditional handover, for example, the PCI.

Alternatively, the priority for the terminal to perform conditional handover in the multiple candidate cells may be indicated, for example, the priority may be implicitly expressed by an order of the multiple candidate cells in signaling;

4. removing cell information of the candidate cell;

5. the random access information may be contention random access information or non-contention random access information. For example, at least one of the following: subcarrier interval, random access preamble, time domain information, frequency domain information, terminal identification and terminal group identification;

further, a plurality of random access information can be configured and applied to different terminals and/or terminal groups. Specifically, the correspondence/mapping relationship between the random access information and the terminal and/or the terminal group is given.

In the implementation, if the RRC reconfiguration message comprises the CFRA, the terminal performs non-competitive random access based on the CFRA resources in the RRC reconfiguration message;

Specifically, if the random access information is included in the first information of the group configuration, the random access information is applied to all UEs within the UE group. The UE in the group adopts competition random access;

if the RRC reconfiguration message includes a CFRA (Contention Free Random Access), the terminal performs the non-Contention Random Access based on the CFRA resource in the RRC reconfiguration message regardless of whether the first information configured in the group includes Random Access information;

and if the RRC reconfiguration message does not comprise the CFRA, the terminal performs random access by adopting the random access information in the first information of the grouping configuration.

In an implementation, the first information of a plurality of grouping configurations can be configured and applied to different grouping UEs. If a plurality of packet first information are configured, the packet configuration conditional command may be identified by a configuration packet identifier.

And secondly, the network issues first information of the grouping configuration.

In the implementation, the terminal receives first information issued by the network side through one or a combination of the following messages:

broadcast messages, multicast messages.

In a specific implementation, the terminal receives first information issued by the network side through one of the following modes or a combination thereof:

broadcast messages, multicast messages.

In implementation, the network side receives a first identifier to the group of terminals, where the first identifier indicates whether to send first information.

Specifically, the first identifier is used to notify the terminal network side whether to send the first information, that is, whether to send the measurement reporting trigger condition information and/or the condition execution condition information and/or the candidate cell information and/or the cell information of the removed candidate cell and/or the random access information.

The first identifier may be issued through a broadcast message, a multicast message, or an RRC reconfiguration message.

In implementation, the network side issues second information to the group of terminals, where the second information is information related to whether the terminal receives or applies the first information.

a terminal identifier, specifically, the terminal identifier may be identified by an RNTI (Radio Network Temporary Identity);

a terminal group identifier, specifically, the terminal group identifier may be an identifier of a terminal group composed of at least one terminal, and the first information may be applied to all terminals in the terminal group;

a terminal identifier in the terminal group;

the identifier of the terminal group to which the terminal belongs;

the second indication information is used to notify the terminal whether to receive or apply the first information, and specifically, the second indication information may indicate whether a certain terminal receives the first information or may indicate whether a certain terminal group receives the first information.

For example, the second indication information may be indicated by 1 bit, for example, the bit position 1 indicates that the terminal needs to receive the first information.

For another example, if the second indication information is configured to true, it indicates that the terminal needs to receive the first information.

A plurality of second indication information can be configured and applied to a plurality of terminals or a plurality of terminal groups;

the terminal may specifically compare the moving speed of the terminal with the first speed threshold to determine whether to use the first information. Specifically, if the moving speed of the terminal is higher than or equal to the first speed threshold, the terminal may use the first information; if the moving speed of the terminal is lower than the speed threshold, the terminal adopts the conditional switching configuration in the RRC reconfiguration message.

broadcast message, multicast message, RRC reconfiguration message.

Specifically, first information carried by the broadcast message, the multicast message or the multicast message is acquired from the issued broadcast message, the multicast message or the multicast message;

when the first information is determined to be received in the broadcast message, the multicast message or the multicast message through the indication in the broadcast message or the RRC message, the first information of the configuration carried by the first information is obtained in the broadcast message, the multicast message or the multicast message which is issued;

when a terminal list issued through an RNTI determines that first information needs to be received in a broadcast message, a multicast message or a multicast message, acquiring the first information of configuration carried by the first information in the issued broadcast message, multicast message or multicast message;

the method comprises the steps of obtaining first information carried by the broadcast message, the multicast message or the multicast message in the broadcast message, the multicast message or the multicast message, receiving a speed threshold issued by the broadcast message, and determining whether to execute the first information according to the speed threshold.

Specifically, the following description will be made separately.

The first method is as follows: and acquiring the first information carried by the broadcast message, the multicast message or the multicast message.

The first information is added to a broadcast, multicast, or multicast message.

The terminal may periodically read the broadcast, multicast, or multicast message to obtain the first information.

In the implementation, still include:

Specifically, if the related information of handover or conditional handover is configured in the RRC reconfiguration message, the terminal first adopts the handover or conditional handover configuration in the RRC reconfiguration message. If no handover or conditional handover configuration is performed in the RRC reconfiguration message, the terminal employs the configured or packet configured first information in the broadcast, multicast, or multicast message. If switching or conditional switching is configured in the RRC reconfiguration message, but the switching or conditional switching information lacks configuration of a part of parameters, the terminal adopts first information configured in a broadcast, multicast or multicast message or configured in a packet for the missing parameter configuration in the RRC reconfiguration message.

The second method comprises the following steps: when the first information is determined to be received in the broadcast message, the multicast message or the multicast message through the indication in the broadcast message or the RRC message, the first information of the configuration carried by the first information is obtained in the broadcast message, the multicast message or the multicast message which is transmitted.

First information of packet configuration is added in a broadcast, multicast, or multicast message. And informs the terminal of issuing the first information in a broadcast, multicast or multicast message through the indication identifier. The indication mark is used to inform the terminal to broadcast, multicast or receive the relevant first information in multicast.

Specifically, the indication identifier may indicate that the terminal only receives the first broadcast, multicast or multicast information; the indication identifier may also be configured such that the terminal receives a part of the conditional handover parameters in broadcast, multicast, or multicast. The indication mark notification can be issued in the following way:

1) sending down through broadcasting;

2) and issuing through an RRC message, for example, adding an indication identifier in an RRC reconfiguration message.

If the terminal receives the indication identification, the terminal performs conditional switch based on the first information in the broadcast, multicast or multicast message.

If the terminal receives the network notification to acquire the first information in the broadcast, multicast or multicast, but the terminal also receives the switching or conditional switching information based on the RRC reconfiguration message, for some parameters, if the switching or conditional switching information in the RRC reconfiguration message and the first information of the broadcast, multicast or multicast are both configured, the terminal adopts the relevant configuration of the first information in the reconfiguration message for the parameters, and for some parameters, only the first information of the broadcast, multicast or multicast is configured, the terminal adopts the relevant configuration of the first information of the broadcast, multicast or multicast for the parameters.

The third method comprises the following steps: when the terminal list issued through the RNTI determines that the first information needs to be received in the broadcast message, the multicast message or the multicast message, the first information carried by the first information is acquired in the issued broadcast message, the multicast message or the multicast message.

On the basis of the first and second modes, a broadcast delivery of a UE list may be added, and the UE list may indicate the UE through an RNTI (Radio Network Temporary Identifier).

Only the UEs in the UE list need to receive the first information configured by broadcast, multicast, or multicast.

The UE list may also indicate grouping, and UEs in different groups may use different first information.

The method is as follows: the method comprises the steps of obtaining first information carried by the broadcast message, the multicast message or the multicast message in the broadcast message, the multicast message or the multicast message, receiving a speed threshold issued by the broadcast message, and determining whether to execute the first information according to the speed threshold.

On the basis of the first mode, the second mode and the third mode, a speed threshold issued by broadcasting can be increased. And the UE judges whether to adopt the first information configured in a broadcasting, multicasting or multicasting mode according to the comparison between the self moving speed and the speed threshold.

Specifically, if the moving speed of the terminal is higher than or equal to the speed threshold, the terminal may use the first information configured in a broadcast, multicast, or multicast manner; if the moving speed of the terminal is lower than the speed threshold, the terminal adopts the switching or conditional switching information in the RRC reconfiguration message.

And thirdly, terminal behavior.

Accordingly, for the implementation on the terminal side, in addition to the behavior corresponding to the network side, the following may be implemented:

in the implementation, still include:

The terminal obtains the first information-related configuration in a broadcast, multicast, or multicast message. The specific method comprises the following modes:

the first method is as follows: the terminal acquires the complete first information in a broadcast, multicast or multicast message.

If the terminal obtains the signaling notification that the complete first information can be obtained in the broadcast, multicast or multicast message, the terminal obtains the first information in the broadcast, multicast or multicast message;

if the terminal obtains the signaling notification and can obtain complete first information in the broadcast, multicast or multicast message, and the terminal also receives the switching or conditional switching information configured by the RRC reconfiguration message, the terminal adopts the switching or conditional switching information configured by the RRC reconfiguration message;

in a scenario that the network does not signal whether the terminal can obtain complete first information in the broadcast, multicast or multicast message, if the terminal does not receive the switching or conditional switching information configured by the RRC reconfiguration message, but the terminal receives the first information in the broadcast, multicast or multicast message, the terminal adopts the first information in the broadcast, multicast or multicast message.

The second method comprises the following steps: the terminal acquires part of the first information in a broadcast, multicast or multicast message and acquires part of switching or conditional switching information in an RRC reconfiguration message.

If the terminal obtains the signaling notification and can obtain part of the first information in the broadcast, multicast or multicast message, the terminal adopts the first information in the broadcast, multicast or multicast message for the corresponding switching or conditional switching parameter;

if the terminal obtains the signaling notification, part of the first information can be acquired in the broadcast, multicast or multicast message, and for part of the parameters, a scene that the first information in the broadcast, multicast or multicast message and the RRC reconfiguration message are both configured exists, at this time, the terminal adopts the configuration of the RRC reconfiguration message. For parameters configured only in broadcast, multicast, or multicast messages, the terminal employs the first information of the broadcast.

In a scene that a network does not inform a terminal whether a part of first information can be acquired in a broadcast, multicast or multicast message through signaling, the broadcast, multicast or multicast message and an RRC reconfiguration message configure switching or conditional switching, and if parameters configured by the broadcast, multicast or multicast message and the RRC reconfiguration message are not overlapped, the terminal acquires complete switching or conditional switching configuration based on the broadcast, multicast or multicast message and the RRC reconfiguration message. If the parameters configured by the two are overlapped, the terminal adopts the switching or conditional switching configuration in the RRC reconfiguration message at the overlapped part, and for the parameters configured by the non-overlapped part, the terminal acquires the relevant switching or conditional switching parameters based on the respective switching or conditional switching configuration in the broadcast, multicast or multicast message and the RRC reconfiguration message.

The following is illustrated by way of example.

Example 1:

in this example, a new SIB (System Information Block) message is added to the broadcast message, and the SIB message carries the first Information. The terminal periodically reads the SIB message to acquire the first information.

If the switching or conditional switching information is configured in the RRC reconfiguration message, the terminal first adopts the switching or conditional switching configuration in the RRC reconfiguration message. If no handover or conditional handover configuration is performed in the RRC reconfiguration message, the terminal employs the first information of the packet configuration in the broadcast or multicast message. If switching or conditional switching information is configured in the RRC reconfiguration message, but the switching or conditional switching information lacks configuration of partial parameters, the terminal adopts first information of packet configuration in a broadcast or multicast message for the missing parameter configuration in the RRC reconfiguration message.

The UE list may be issued in a broadcast message, and the UE belonging to the UE list may determine the first information to be used based on the above scheme.

Or, a speed threshold may be issued in the broadcast message, and if the moving speed of the terminal is higher than or equal to the speed threshold, the terminal may determine the adopted first information based on the above scheme; if the moving speed of the terminal is lower than the speed threshold, the terminal adopts the switching or conditional switching configuration in the RRC reconfiguration message, or does not adopt the first information sent in the broadcast, multicast or multicast message.

Example 2:

in this example, first information is added to the broadcast message, and the first information is carried by the existing SIB message. The terminal periodically reads the SIB message to acquire the first information.

Example 3:

in this example, a new SIB message is added to the broadcast message, and the SIB message carries the first information. The network issues the indication mark to inform the terminal that the first information can be obtained in the broadcast message.

An embodiment of the present invention provides a computer-readable storage medium, which is characterized in that the computer-readable storage medium stores a computer program for executing the handover or conditional handover CHO configuration method and/or the handover or conditional handover CHO configuration receiving method of the claims.

The specific implementation may refer to the implementation of a handover or conditional handover CHO configuration method and/or a handover conditional handover CHO configuration receiving method.

In summary, in the technical solution provided in the embodiment of the present invention, the configuration information for conditional switching is issued in a grouping manner, and the configuration information may be applied to a plurality of UEs.

The first information of the packet may be delivered by broadcast or multicast, or multicast.

The terminal may be informed of the presence or absence of the first information of the packet through network signaling. The signaling notification may be broadcast or may be an RRC message.

The terminal may obtain the handover or conditional handover configuration based on the broadcast alone; the terminal may also jointly acquire a handover or conditional handover configuration based on the broadcast and RRC reconfiguration messages.

In the prior art, the network performs related configuration of conditional switching for each UE through an RRC reconfiguration message. In a high-speed rail and other scenes, the UEs in one compartment are usually switched at the same time, and since the high-speed rail line is relatively fixed, and the candidate target cells for switching are also usually the same, for such a scene, the related configuration of switching or conditional switching can be performed in a grouping manner, and parameters common to the UEs in the group are issued in a common manner, so that the signaling overhead can be effectively reduced.
