Description

Wireless communication method, terminal equipment and network equipment

Technical Field

The embodiment of the application relates to the field of communication, and more particularly relates to a wireless communication method, terminal equipment and network equipment.

Background

The third generation partnership project (3rd Generation Partnership Project,3GPP) defines a conditional change of primary and secondary cells (conditional PSCELL CHANGE, CPC), a conditional addition of primary and secondary cells (Conditional PSCell Addition, CPA) and a Conditional HandOver (CHO). The main idea of CPC is that a network device may configure a CPC configuration to a terminal device, the CPC configuration comprising: the terminal device may continuously monitor whether the candidate cells satisfy the CPC execution condition or not according to the configuration and the CPC execution condition of the plurality of candidate primary and secondary cells (Primary Secondry Cell, PScell), and once the candidate cells satisfy the CPC execution condition, perform the CPC procedure, that is, change the original PScell to the candidate cell, and further release the CPC configuration. Similarly, the main idea of CPA is that a network device can configure a CPA configuration to a terminal device, the CPA configuration comprising: the configuration of the plurality of candidates PScell and the CPA execution condition, the terminal device may continuously monitor whether the candidate cell satisfies the CPA execution condition, and once the candidate cell satisfies the CPA execution condition, perform the CPA procedure, that is, the candidate cell is regarded as PScell, and further release the CPA configuration. Whereas the main idea of CHO is that a network device can configure a CHO configuration to a terminal device, the CHO configuration comprising: and once the candidate cells meet the CHO execution conditions, executing a CHO process, namely taking the candidate cells as target cells, switching the terminal equipment from the source cells to the target cells, and further releasing the CHO configuration.

As described above, for any one of the CPC procedure, the CPA procedure, and the CHO procedure, once the procedure is performed, the terminal device releases the configuration corresponding to the procedure. However, on the one hand, if the network device needs to initiate the procedure again, the network device needs to perform the corresponding configuration for the terminal device again, which definitely causes additional signaling overhead and communication delay, and on the other hand, as the terminal device moves, if the CPC configuration, CPA configuration or CHO configuration corresponding to the terminal device is not changed all the time, this may not be suitable for the mobility requirement of the terminal device.

The following describes the relevant knowledge of the technical scheme of the application:

1. CPC execution conditions:

A CPC execution condition may include: one or two trigger conditions, which are CPC events, but are not limited thereto:

Event A3: the signal quality of the adjacent cell is higher than that of the PCell/PScell by a certain offset;

event A5: the signal quality of the PCell/PSCell is below an absolute threshold 1 and the signal quality of the neighboring Cell/Secondary Cell (SCell) is above an absolute threshold 2;

2. CPA execution conditions:

a CPA execution condition may include: one or two trigger conditions, which are, but are not limited to, CPA events as follows:

Event A4: the signal quality of the adjacent cell is higher than an absolute threshold;

Event B1: the signal quality of the adjacent cell is higher than a specified threshold;

3. CHO execution conditions:

a CHO execution condition may include: one or two trigger conditions, which are but not limited to CHO events as follows:

Conditional event A3: the signal quality of the conditionally reconfigured PCell is higher than the signal quality of the PCell by a certain offset;

Conditional event A5: the signal quality of the PCell is below an absolute threshold 1 and the signal quality of the conditionally reconfigured PCell is above an absolute threshold 2.

4. Principle followed by CPC:

The CPC configuration contains the configuration of a plurality of candidate pscells and the SN/MN generated CPC execution conditions.

One execution condition may comprise one or two trigger conditions, supporting only a single reference signal (REFERENCE SIGNAL, RS) type, at most two different trigger amounts (e.g. reference signal received power (REFERENCE SIGNAL RECEIVING power, RSRP), reference signal received quality (REFERENCE SIGNAL RECEIVING quality, RSRQ), reference signal received power (REFERENCE SIGNAL RECEIVING power, RSRP), and signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR), etc.) may be configured simultaneously for evaluating CPC execution conditions of a single candidate PSCell.

-Before any CPC execution conditions are met, after receiving a PSCell change command or PCell change command, the terminal device performs a PSCell change procedure described in sections 10.3 and 10.5 or a PCell change procedure described in section 9.2.3.2 in TS38.300, regardless of any CPC configuration previously received. After successfully completing the PSCell change procedure or the PCell change procedure, the terminal device releases all stored CPC configurations.

In performing CPC, the terminal device is not required to continue evaluating CPC performance conditions of other candidate pscells.

Once the CPC procedure is successfully executed, the terminal device releases all stored CPC configurations.

-Upon release of the secondary cell group (Secondary Cell Group, SCG), the terminal device releases the stored CPC configuration.

4. The CPA follows the principle:

the MN decides to configure the CPA to the terminal device and sends an SN addition request to the candidate SN.

-Upon receipt of the SN addition request feedback acknowledgement of the candidate SN, the MN sends a CPA configuration to the terminal device, including a CPA configuration message (RRCConnectionReconfiguration message) comprising the candidate SN configuration and the corresponding execution conditions.

The terminal device evaluates the configured execution conditions, and if the execution conditions of a candidate PSCell are met, the terminal device sends a reconfiguration complete message to the PScell, wherein the terminal device can send the reconfiguration complete message to the MN, which in turn forwards the message to the SN.

Further terminal device initiates a synchronization procedure, i.e. a random access procedure, towards the PScell.

5. CHO follows the principle:

the CHO configuration includes the configuration of candidate cells generated by the candidate gNB and the execution conditions of the source gNB generation.

An execution condition may consist of one or two trigger conditions. Only one RS type is supported, and at most two different triggers (such as RSRP and RSRQ, RSRP and SINR, etc.) can be configured simultaneously to evaluate CHO performance of a single candidate cell.

-The terminal device performs the HO procedure described in section 9.2.3.2 in TS38.300, before any CHO execution conditions are met, upon receipt of a HandOver (HO) command, without CHO configuration, no matter what CHO configuration was received before.

When CHO is performed, i.e. starting from the time when the terminal device starts synchronizing with the target cell, the terminal device does not monitor the source cell.

The technical scheme of the application will be described in detail as follows:

fig. 2 is an interaction flow chart of a wireless communication method according to an embodiment of the present application, as shown in fig. 2, where the method includes:

s210: the network device sends a first configuration and first information to the terminal device, wherein the first configuration comprises any one of the following: CPC configuration, CPA configuration, conditional addition change primary secondary cell (Conditional PSCell Addition Change, CPAC) configuration, CHO configuration, first information for determining validity of the first configuration;

S220: and the terminal equipment releases the first configuration according to the first information.

In some implementations, the first configuration includes: configuration and execution conditions of at least one candidate cell. For example: assuming that the first configuration is CPC configuration, the configuration of at least one candidate cell refers to the configuration of at least one PScell, and the execution condition is CPC execution condition; assuming that the first configuration is a CPA configuration, the configuration of at least one candidate cell refers to the configuration of at least one PScell, and the execution condition is a CPA execution condition; assuming that the first configuration is CPAC configurations, that is, the CPAC configuration is a set of configurations that are common to the CPA process and the CPC process, in actual implementation, the CPA process may be performed first and then the CPC process may be performed, where the configuration of at least one candidate cell included in the CPAC configuration refers to the configuration of at least one PScell, and the implementation condition is CPAC implementation condition; assuming that the first configuration is a CHO configuration, the configuration of the at least one candidate cell refers to the configuration of the at least one Pcell, and the execution condition is a CHO execution condition.

In some implementations, the first configuration further includes: the activation or deactivation status information corresponding to the at least one candidate cell, in some implementations, the configuration of the at least one candidate cell includes at least one of: radio resource bearer configuration, protocol stack configuration, security key related configuration for each candidate cell.

Illustratively, the configuration of the candidate cell may include at least one of, but is not limited to: the identification of the candidate cell, the new cell radio network temporary identification (Cell Radio Network Temporary Identifier, C-RNTI), the security algorithm identification of the network device corresponding to the candidate cell, the relationship between the dedicated Random access channel (Random ACCESS CHANNEL, RACH), RACH resources and single side bands (SINGLE SIDE bands, SSBs), the relationship between RACH resources and UE specific channel state information-reference signal (CHANNEL STATE information-REFERENCE SIGNAL, CSI-RS) configuration, the common RACH resources and system information corresponding to the candidate cell, and the like.

In some implementations, the first configuration is a full configuration. For example: the candidate cell configurations in the first configuration are all absolute configurations, and the first information may be absolute values.

In some implementations, the first configuration is an incremental configuration relative to a reference configuration, which may be, but is not limited to, a configuration of a source cell, a configuration of SN settings, or a configuration of a primary secondary cell, etc.

In some implementations, the first information is configuration information of a timer.

In some implementations, the network device may predict how long the terminal device should not need to update the CPC configuration, CPAC configuration, CPA configuration, or CHO configuration and set that time range to the running duration of the timer.

In some implementations, the network device may send the first configuration and the first information separately, or may send the first configuration and the first information together, for example: the network device may send the first configuration and the first information to the terminal device in a certain message. The start/restart condition of the timer comprises receiving the first configuration and/or the first information.

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

1.a message is received that the network releases the CPC/CPA/CHO configuration.

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

3. The sequential CPC/CPA/CHO procedure ends.

4. Triggering RRC connection re-establishment.

In some implementations, when the timer expires, the terminal device may deactivate the first configuration, i.e. indicate that the first configuration is invalid, and further the terminal device may release the first configuration.

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

In some implementations, when/after the timer has stopped running, the terminal device may restart the timer when the terminal device receives the first configuration and the first information again. 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 accordingly, the first information received by the terminal device twice is also different, for example: assuming that the first configuration is CPC configuration, the CPC configuration received by the terminal device twice is different, and correspondingly, the first information corresponding to the CPC configuration received twice is naturally different.

In some implementations, the first information is any one of, but not limited to:

(1) Carrying out CPC, CPA, CPAC or the maximum allowable number of CHO according to the first configuration, wherein the maximum allowable number is a positive integer;

(2) Carrying out CPC, CPA, CPAC or the maximum allowable success times of CHO according to the first configuration, wherein the maximum allowable success times are positive integers;

(3) Carrying out CPC, CPA, CPAC or the maximum allowable failure times of CHO according to the first configuration, wherein the maximum allowable failure times are positive integers;

in this implementation, the first information may be predefined by a standard, or may be configured by a network device, which is not limited by the present application.

In some implementations, the maximum allowed number may be a maximum allowed number that there is at least one candidate cell satisfying the execution condition and the terminal device executes CPC, CPA, CPAC or CHO.

In some implementations, the maximum allowed number of successes may be a maximum allowed number of random access successes.

In some implementations, the maximum allowed number of failures may be a maximum allowed number of random access failures.

It should be appreciated that when the terminal device determines that at least one candidate cell satisfies the execution condition corresponding to the first configuration, it may execute CPC, CPA, CPAC or CHO, for example: the terminal device may continuously monitor whether the candidate cell satisfies the CPC execution condition, and once the candidate cell satisfies the CPC execution condition, perform the CPC procedure, that is, change the original PScell to the candidate cell. Or the terminal device may continuously monitor whether the candidate cell satisfies the CPA execution condition, and once there is a candidate cell satisfying the CPA execution condition, perform the CPA procedure, i.e. add the candidate cell as PScell. Or once the candidate cell exists and meets the CHO execution condition, executing a CHO process, namely taking the candidate cell as a target cell, and switching the terminal equipment from the source cell to the target cell. Thus, for the same first configuration, the terminal device may determine CPC, CPA, CPAC or the actual number of CHO.

In some implementations, when the first information includes: CPC, CPA, CPAC or CHO, then the first configuration is indicated as invalid when the actual number of CPC, CPA, CPAC or CHO according to the first configuration determined by the terminal device is greater than the maximum number of allowed times, and conversely the first configuration is indicated as valid when the actual number of CPC, CPA, CPAC or CHO according to the first configuration determined by the terminal device is less than or equal to the maximum number of allowed times.

In some implementations, when the first information includes: CPC, CPA, CPAC or CHO, then when the actual number of CPC, CPA, CPAC or CHO according to the first configuration determined by the terminal device is greater than the maximum number of allowed successes, then the first configuration is not valid, and conversely when the actual number of CPC, CPA, CPAC or CHO according to the first configuration determined by the terminal device is less than or equal to the maximum number of allowed successes, then the first configuration is valid.

In some implementations, when the first information includes: CPC, CPA, CPAC or CHO, then when the actual number of CPC, CPA, CPAC or CHO according to the first configuration determined by the terminal device is greater than the maximum number of allowed failures, the first configuration is indicated to be invalid, and conversely when the actual number of CPC, CPA, CPAC or CHO according to the first configuration determined by the terminal device is less than or equal to the maximum number of allowed failures, the first configuration is indicated to be valid.

In some implementations, the terminal device may release the first configuration when the actual number of times CPC, CPA, CPAC or CHO is greater than the maximum number of times allowed or the maximum number of times allowed to succeed or the maximum number of times allowed to fail, i.e., the terminal device determines that the first configuration is invalid.

In some implementations, the first information includes: at least one signal quality threshold, the first configuration comprising: configuration of at least one candidate cell; the configuration of the candidate cell has a corresponding relation with the signal quality threshold.

In some implementations, the signal quality herein can be measured by at least one of RSRP, RSRP, RSRQ and SINR.

In some implementations, the 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, as the application is not limited in this regard.

In some implementations, the correspondence between the configuration of the candidate cells and the signal quality threshold is a one-to-one correspondence or a many-to-one correspondence. For example: assuming that there are 5 candidate cell configurations, each candidate cell configuration corresponds to a signal quality threshold that differs, for example: it is assumed that there are 5 candidate cell configurations, which all correspond to one and the same signal quality threshold. Also for example: it is assumed that there are 5 candidate cell configurations, of which 3 correspond to one signal quality threshold and the other 2 correspond to one signal quality threshold.

In some implementations, for the at least one candidate cell, if there are at least N candidate cells with signal qualities less than the corresponding signal quality thresholds, the terminal device determines that the first configuration is invalid, where N is a positive integer, where N may be predefined by a standard or configured by a network device, and the application is not limited in this regard.

Illustratively, assuming n=3, the first configuration includes: and 5 candidate cells are configured, and if the signal quality of at least 3 candidate cells is smaller than the corresponding signal quality threshold value, the terminal equipment determines that the first configuration is invalid.

In some implementations, the terminal device may release the first configuration when the signal quality of the at least N candidate cells is less than the corresponding signal quality threshold, i.e. the terminal device determines that the first configuration is invalid.

In some implementations, assuming that any one of the at least one candidate cell is referred to as a first candidate cell, the terminal device may determine that the configuration of the first candidate cell is invalid when the signal quality of the first candidate cell is less than the corresponding signal quality threshold, and further may release the configuration of the first candidate cell when the terminal device determines that the configuration of the first candidate cell is invalid.

In summary, through the technical solution provided in the present application, the terminal device may release the first configuration according to the first information, for example: when the first configuration is determined to be invalid according to the first information, the first configuration is released, and on the contrary, when the first configuration is determined to be valid according to the first information, CPC, CPA, CPAC or CHO is executed, on the one hand, compared with the prior art that the corresponding configuration is released after the terminal equipment completes CPC, CPA, CPAC or CHO each time, the first configuration is released only when the first configuration is invalid, for example: the first configuration may be used multiple times in succession, which may reduce additional signaling overhead and communication latency; on the other hand, if the terminal device moves far, its first configuration may have failed, and the terminal device releases the first configuration, so that the mobility requirement of the terminal device can be better adapted.

Fig. 3 is an interaction flow chart of a wireless communication method according to an embodiment of the present application, as shown in fig. 3, where the method includes:

S310: the network device sends first configuration and second information to the terminal device, wherein the first configuration comprises any one of the following: CPC configuration, CPA configuration, CPAC configuration, CHO configuration, the second information being used to indicate release of the first configuration;

S320: and the terminal equipment releases the first configuration according to the second information.

It will be appreciated that the first configuration is explained with reference to the above, to which the application is not limited.

In some implementations, the second information is carried in a radio resource control (Radio Resource Control, RRC) message, a medium access control unit (MEDIA ACCESS Control Control Element, MAC CE), or downlink control information (Downlink Control Information, DCI), but is not limited thereto.

In some implementations, the terminal device may send the auxiliary information to the network device before the network device sends the first configuration and the second information to the terminal device; wherein the auxiliary information is used to assist the network device in determining whether to release the first configuration, 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 for the current camping cell, the network device compares the channel measurement result with a corresponding threshold value, and if the channel measurement result is lower than the corresponding threshold value, the network device may send second information to the terminal device, i.e. release the first configuration.

In some implementations, after the terminal device releases the first configuration according to the second information, the terminal device may send indication information to the network device; wherein the indication information is used for indicating that the first configuration has been released.

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

According to the technical scheme provided by the application, the terminal equipment can release the first configuration according to the second information, on one hand, compared with the prior art that the terminal equipment releases the corresponding configuration after CPC, CPA, CPAC or CHO is executed each time, the first configuration is released only when the first configuration is invalid, for example: the first configuration may be used multiple times in succession, which may reduce additional signaling overhead and communication latency; on the other hand, if the terminal device moves far, its first configuration may have failed, and the terminal device releases the first configuration, so that the mobility requirement of the terminal device can be better adapted.

Fig. 4 is a schematic diagram of a terminal device 400 according to an embodiment of the present application, as shown in fig. 4, the terminal device 400 includes: a communication unit 410 and a processing unit 420, wherein the communication unit 410 is configured to: receiving a first configuration and first information, the first configuration comprising any one of: CPC configuration, CPA configuration, CPAC configuration, CHO configuration, first information is used to determine the validity of the first configuration; the processing unit 420 is configured to release the first configuration according to the first information.

In some implementations, the first configuration is indicated as invalid when the timer expires or expires.

In some implementations, the starting condition of the timer includes receiving the first configuration and/or the first information.

In some implementations, the first information is any one of:

carrying out CPC, CPA, CPAC or the maximum allowable number of CHO according to the first configuration;

Carrying out CPC, CPA, CPAC or the maximum allowable success times of CHO according to the first configuration;

carrying out CPC, CPA, CPAC or the maximum allowable failure times of CHO according to the first configuration;
