Description

Wireless communication method, terminal device and network device

technical field

The embodiments of the present application relate to the communication field, and more specifically, relate to a wireless communication method, a terminal device, and a network device.

Background technique

The 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) defines conditionally changing primary and secondary cells (Conditional PSCell Change, CPC), conditionally adding primary and secondary cells (Conditional PSCell Addition, CPA) and conditional handover ( Conditional HandOver, CHO). The main idea of CPC is that the network device can configure the CPC configuration to the terminal device. The CPC configuration includes: the configuration of multiple candidate Primary Secondary Cells (PScell) and the CPC execution conditions, and the terminal device can continuously monitor whether the candidate cells meet the CPC requirements. Execution condition, once there is a candidate cell that satisfies the CPC execution condition, the CPC process is executed, that is, the original PScell is changed to the candidate cell, and the CPC configuration is further released. Similarly, the main idea of CPA is that the network device can configure the CPA configuration to the terminal device. The CPA configuration includes: the configuration of multiple candidate PScells and the CPA execution conditions. The terminal device can continuously monitor whether the candidate cells meet the CPA execution conditions. If the cell satisfies the CPA execution condition, the CPA process is executed, that is, the candidate cell is used as a PScell, and the CPA configuration is further released. The main idea of CHO is that the network device can configure the CHO configuration to the terminal device. The CHO configuration includes: the configuration of multiple candidate cells and the CHO execution conditions. Once a candidate cell meets the CHO execution conditions, the CHO process will be executed, that is, the candidate cell As a target cell, the terminal device is handed over from the source cell to the target cell, and further releases the CHO configuration.

As mentioned above, for any one of the CPC process, the CPA process and the CHO process, once the process is executed, the terminal device will release the configuration corresponding to the process. However, on the one hand, if the network device needs to initiate the process again, the network device needs to configure the terminal device again, which will undoubtedly cause additional signaling overhead and communication delay; on the other hand, as the terminal device Mobile, if the CPC configuration, CPA configuration or CHO configuration corresponding to the terminal device has not changed, this may not be able to meet the mobility requirements of the terminal device.

- Before any CPC execution conditions are satisfied, upon receipt of a PSCell change command or a PCell change command, the terminal device performs the PSCell change procedure described in Sections 10.3 and 10.5 or the PCell change described in Section 9.2.3.2 of TS38.300 process, regardless of any previously received CPC configuration. After successfully completing the PSCell change procedure or the PCell change procedure, the terminal device releases all stored CPC configurations.

- When executing CPC, it is not necessary for the terminal device to continue evaluating the CPC execution conditions of other candidate PSCells.

- Once the CPC procedure has been successfully executed, the terminal device releases all stored CPC configurations.

- When the secondary cell group (Secondary Cell Group, SCG) is released, the terminal device releases the stored CPC configuration.

- Before any CHO execution conditions are met, when receiving a handover (HandOver, HO) command, no CHO configuration, regardless of any previous CHO configuration received, the terminal device executes the HO procedure described in Section 9.2.3.2 of TS38.300 .

- When performing CHO, ie from when the terminal device starts to synchronize with the target cell, the terminal device does not monitor the source cell.

The technical scheme of the present application will be described in detail below:

Fig. 2 is an interactive flow chart of a wireless communication method provided by the embodiment of the present application. As shown in Fig. 2, the method includes:

S210: The network device sends the first configuration and the first information to the terminal device, the first configuration includes any of the following: CPC configuration, CPA configuration, conditional addition and change of primary and secondary cell (Conditional PSCell Addition Change, CPAC) configuration, CHO configuration, the first information is used to determine the validity of the first configuration;

S220: The terminal device releases the first configuration according to the first information.

In some implementable manners, the first configuration includes: configuration and execution conditions of at least one candidate cell. For example: assuming that the first configuration is CPC configuration, then the configuration of at least one candidate cell refers to the configuration of at least one PScell, and the execution condition is the CPC execution condition; assuming that the first configuration is CPA configuration, then the configuration of at least one candidate cell refers to It is the configuration of at least one PScell, and the execution condition is the CPA execution condition; assuming that the first configuration is CPAC configuration, that is, the CPAC configuration is a common set of configurations for the CPA process and the CPC process. In actual execution, CPA can be executed first. process, and then execute the CPC process, the configuration of at least one candidate cell included in the CPAC configuration refers to the configuration of at least one PScell, and the execution condition is the CPAC execution condition; assuming that the first configuration is CHO configuration, then the configuration of at least one candidate cell It refers to the configuration of at least one Pcell, and the execution condition is the CHO execution condition.

In some implementable manners, the first configuration further includes: activation or inactivation status information corresponding to at least one candidate cell. In some implementable manners, the configuration of at least one candidate cell includes at least one of the following: each candidate cell Radio resource bearer configuration, protocol stack configuration, and security key related configuration.

Exemplarily, the configuration of the candidate cell may include at least one of the following, but is not limited thereto: an identifier of the candidate cell, a new cell radio network temporary identifier (Cell Radio Network Temporary Identifier, C-RNTI), a network device corresponding to the candidate cell Security algorithm identification, dedicated Random Access Channel (Random Access CHannel, RACH), RACH resources and the relationship between Single Side Band (Single Side Band, SSB), RACH resources and UE-specific channel state information-reference signal (channel State information-Reference Signal, CSI-RS) configuration relationship, common RACH resources and system information corresponding to candidate cells, etc.

In some implementable manners, the first configuration is a full configuration. For example, the configurations of the candidate cells in the first configuration are all absolute configurations, and the first information may also be an absolute value.

In some implementable manners, the first configuration is an incremental configuration relative to a reference configuration, and the reference configuration may be a configuration of a source cell, a configuration of an SN setting, or a configuration of a primary and secondary cell, but is not limited thereto.

In some implementable manners, the first information is timer configuration information.

In some implementable manners, the network device may predict a time range within which the terminal device should not need to update the CPC configuration, CPAC configuration, CPA configuration or CHO configuration, and set the time range as the running duration of the timer.

In some implementation manners, the network device may send the first configuration and the first information separately, or send the first configuration and the first information together. For example, the network device may carry the first configuration and the first information in a message sent to the terminal device. The start/restart condition of the timer includes receiving the first configuration and/or the first information.

The stop condition of the timer includes at least one of the following:

1. Receive the message that the network releases the CPC/CPA/CHO configuration.

2. A traditional switching command or other unconditional switching command is received, such as a dual active protocol stack (Dual Active Protocol Stack, DAPS) switching command.

3. The continuous CPC/CPA/CHO process ends.

4. Trigger RRC connection re-establishment.

In some implementable manners, when the timer stops, the terminal device stops using the first configuration, which means that the first configuration is invalid, and further, the terminal device may release the first configuration.

In some implementable manners, when the timer expires, the first configuration is considered invalid, and further, the terminal device may release the first configuration.

In some implementable manners, when/after the timer stops running, when the terminal device receives the first configuration and the first information again, the terminal device may restart the timer. It should be noted that the first configuration received by the terminal device again is different from the first configuration received by the terminal device in S210, and correspondingly, the first information received twice by the terminal device is also different. For example, assuming that the first If the configuration is a CPC configuration, then the CPC configurations received twice by the terminal device are different, and correspondingly, the first information corresponding to the CPC configurations received twice is also naturally different.

In some practicable manners, the first information is any of the following, but not limited thereto:

(1) The maximum allowable number of times for CPC, CPA, CPAC or CHO according to the first configuration, the maximum allowable number of times is a positive integer;

(2) According to the first configuration, the maximum allowable success times of CPC, CPA, CPAC or CHO are performed, and the maximum allowable success times are positive integers;

(3) The maximum allowable number of failures of CPC, CPA, CPAC or CHO according to the first configuration, where the maximum allowable number of failures is a positive integer;

In this practicable manner, the first information may be predefined by a standard, and of course may also be configured by a network device, which is not limited in this application.

In some practicable manners, the maximum allowed times may be the maximum allowed times for which there is at least one candidate cell that satisfies the execution condition and the terminal device executes CPC, CPA, CPAC or CHO.

In some implementable manners, the maximum allowed number of successes may be the maximum allowed number of successful random accesses.

In some implementable manners, the maximum allowed number of failures may be the maximum allowed number of random access failures.

It should be understood that when the terminal device determines that at least one candidate cell satisfies the execution condition corresponding to the first configuration, it can execute CPC, CPA, CPAC or CHO, for example: the terminal device can continuously monitor whether the candidate cell satisfies the CPC execution condition, Once a candidate cell satisfies the CPC execution condition, the CPC process is executed, that is, the original PScell is changed to the candidate cell. Alternatively, the terminal device may continuously monitor whether a candidate cell satisfies the CPA execution condition, and once a candidate cell satisfies the CPA execution condition, the CPA process is executed, that is, the candidate cell is added as a PScell. Or, once a candidate cell satisfies the CHO execution condition, the CHO process is executed, that is, the candidate cell is used as the target cell, and the terminal device is handed over from the source cell to the target cell. Therefore, for the same first configuration, the terminal device can determine the actual times of CPC, CPA, CPAC or CHO.

In some practicable manners, when the first information includes: the maximum allowable number of CPC, CPA, CPAC or CHO, then the actual number of CPC, CPA, CPAC or CHO determined by the terminal device according to the first configuration is greater than the The maximum allowable number of times indicates that the first configuration is invalid; on the contrary, when the actual number of CPC, CPA, CPAC or CHO determined by the terminal device according to the first configuration is less than or equal to the maximum allowable number of times, it indicates that the first configuration is valid.

In some practicable manners, when the first information includes: the maximum allowable number of successes of CPC, CPA, CPAC or CHO, then the actual number of times of CPC, CPA, CPAC or CHO determined by the terminal device according to the first configuration is greater than When the maximum allowable number of successes is used, it indicates that the first configuration is invalid; on the contrary, when the actual number of CPC, CPA, CPAC or CHO determined by the terminal device according to the first configuration is less than or equal to the maximum allowable number of successes, it indicates that the first configuration efficient.

In some practicable manners, when the first information includes: the maximum allowable failure times of CPC, CPA, CPAC or CHO, then the actual number of CPC, CPA, CPAC or CHO determined by the terminal device according to the first configuration is greater than When the maximum allowable number of failures is used, it means that the first configuration is invalid; on the contrary, when the actual number of CPC, CPA, CPAC or CHO determined by the terminal device according to the first configuration is less than or equal to the maximum allowed number of failures, it means that the first configuration efficient.

In some implementable manners, when the actual number of CPC, CPA, CPAC or CHO is greater than the maximum allowable number of times or the maximum allowable number of successes or the maximum allowable number of failures, the terminal device determines that the first configuration is invalid , the terminal device may release the first configuration.

In some implementable manners, the first information includes: at least one signal quality threshold, and the first configuration includes: a configuration of at least one candidate cell; where there is a correspondence between the configuration of the candidate cell and the signal quality threshold.

In some implementable manners, the signal quality here can be measured by at least one of RSRP, RSRP, RSRQ and SINR.

In some practicable manners, at least one signal quality threshold may be an absolute threshold involved in a CPC event, or an absolute threshold involved in a CPA event, or an absolute threshold involved in a CHO event, which is not limited in the present application .

In some implementable manners, the correspondence between configurations of candidate cells and signal quality thresholds is a one-to-one correspondence or a many-to-one correspondence. For example: suppose there are 5 candidate cell configurations, and each candidate cell configuration corresponds to a signal quality threshold, and these signal quality thresholds are different. Same signal quality threshold. Another example: assume that there are 5 candidate cell configurations, among these candidate cells, the configurations of 3 candidate cells correspond to a signal quality threshold, and the configurations of the other 2 candidate cells correspond to a signal quality threshold.

In some implementable manners, for the at least one candidate cell, if there are at least N candidate cells whose signal quality is less than the corresponding signal quality threshold, the terminal device determines that the first configuration is invalid, and N is a positive integer, where N can be It is predefined by a standard, or is configured by a network device, which is not limited in this application.

For example, assuming that N=3, assuming that the first configuration includes: a configuration of 5 candidate cells, if there are at least 3 candidate cells whose signal quality is lower than the corresponding signal quality threshold, the terminal device determines that the first configuration is invalid.

In some implementable manners, when the signal quality of at least N candidate cells is lower than a corresponding signal quality threshold, that is, when the terminal device determines that the first configuration is invalid, the terminal device may release the first configuration.

In some practicable manners, assuming that any one of the at least one candidate cell is called the first candidate cell, when the signal quality of the first candidate cell is less than the corresponding signal quality threshold, the terminal device may determine that the first candidate cell The configuration of the candidate cell is invalid. Further, when the terminal device determines that the configuration of the first candidate cell is invalid, it may release the configuration of the first candidate cell.

To sum up, through the technical solution provided by this application, the terminal device can release the first configuration according to the first information, for example: when it is determined that the first configuration is invalid according to the first information, release the first configuration; When the information confirms that the first configuration is valid, execute CPC, CPA, CPAC or CHO. On the one hand, compared with the prior art, the terminal device must release the corresponding configuration each time after executing CPC, CPA, CPAC or CHO. The technology of this application The solution releases the first configuration only when the first configuration is invalid. For example, the first configuration can be used continuously for many times, which can reduce the additional signaling overhead and communication delay; on the other hand, if the terminal device moves If the distance is long, the first configuration may be invalid. At this time, the terminal device will release the first configuration, so that it can be better adapted to the mobility requirements of the terminal device.

Fig. 3 is an interactive flow chart of a wireless communication method provided in the embodiment of the present application. As shown in Fig. 3, the method includes:

S310: The network device sends the first configuration and second information to the terminal device, the first configuration includes any of the following: CPC configuration, CPA configuration, CPAC configuration, and CHO configuration, and the second information is used to indicate release of the first configuration;

S320: The terminal device releases the first configuration according to the second information.

It should be understood that the description of the first configuration may refer to the above, and the present application does not limit this.

In some practicable manners, the second information is carried in a radio resource control (Radio Resource Control, RRC) message, a media access control element (Media Access Control Control Element, MAC CE) or a downlink control information (Downlink Control Information, DCI) in, but not limited to.

In some implementable manners, before the network device sends the first configuration and the second information to the terminal device, the terminal device may send auxiliary information to the network device; where the auxiliary information is used to assist the network device in determining whether to release the first configuration, the The auxiliary information may be a signal measurement result. For example, the signal measurement result may be a channel measurement result of the terminal device on the cell where it is currently camping. The network device compares the channel measurement result with a corresponding threshold. If the channel measurement result is lower than the The corresponding threshold, then the network device may send the second information to the terminal device, that is, release the first configuration.

In some implementable manners, after the terminal device releases the first configuration according to the second information, the terminal device may send indication information to the network device; where the indication information is used to indicate that the first configuration has been released.

In some implementable manners, before the terminal device releases the first configuration according to the second information, the terminal device may also trigger the network device to update the first configuration.

Through the technical solution provided by this application, the terminal device can release the first configuration according to the second information. On the one hand, compared with the prior art, the terminal device must release the corresponding configuration every time it executes CPC, CPA, CPAC or CHO. The technical solution of the present application releases the first configuration only when the first configuration is invalid, for example: the first configuration can be used continuously for multiple times, thereby reducing additional signaling overhead and communication delay; on the other hand, if The terminal device moves a long distance, and its first configuration may be invalid. At this time, the terminal device releases the first configuration, so that it can better meet the mobility requirements of the terminal device.
