Description

Technical Field

[0002] In New Radio (NR) version 18 (R18), in order to improve mobility performance, continuous switching of low-layer triggered mobility (Layer1 / 2 Triggered Mobility, LTM) and continuous condition update of primary secondary cell (PScell) in NR dual connectivity (Dual connectivity, DC) are introduced.

The terminal equipment may also be referred to as User Equipment (UE), a terminal, etc.

[0048] As described in the background technology, in actual configuration, there may be unreasonable parameters, which may cause the terminal device to evaluate unnecessary candidate cells or evaluate candidate cells for a long time, resulting in increased power consumption or measurement burden of the terminal device.

[0049] The technical solution of the present application enables the network device to promptly obtain information related to the continuous condition update of the primary and secondary cells in the dual connection scenario and / or information related to the low-layer triggered mobility LTM continuous switching, such as candidate primary and secondary cells / candidate LTM cells with low signal quality, by enabling the terminal device to record and report the first information, thereby assisting the network device to reasonably configure the parameters in the continuous condition update of LTM continuous switching / PScell, such as updating the candidate primary and secondary cells / candidate LTM cells that need to be measured, reducing unnecessary measurements of the terminal device, and reducing the power consumption of the terminal device.

[0050] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0051] See also Figure 1 The method provided in this application specifically includes the following steps:

[0052] Step 101: The terminal device reports first information. Correspondingly, the network device receives the first information.

[0053] The first information includes information related to continuous condition update of primary and secondary cells in a dual-connectivity scenario and / or information related to continuous mobility LTM switching triggered by a lower layer.

[0054] It should be pointed out that the serial numbers of the steps in this embodiment do not limit the execution order of the steps.

[0055] It is understandable that, in a specific implementation, the communication method can be implemented in the form of a software program, which runs in a processor integrated inside a chip or a chip module. The method can also be implemented in the form of software combined with hardware, which is not limited in this application.

[0056] In this embodiment, the terminal device records the first information, and carries the first information in appropriate signaling to report it to the network device.

[0057] In a specific implementation, the terminal device may carry the first information in a radio resource control (RRC) establishment completion signaling.

[0058] In another specific implementation, the terminal device may carry the first information in the RRC reconfiguration completion signaling.

[0059] In another specific implementation, the terminal device may carry the first information in the RRC recovery completion signaling.

[0060] The embodiments of the present application can be applied to the scenarios of continuous switching of LTM or continuous conditional update of PScell, which will be described below in conjunction with specific scenarios.

[0061] 1. Continuous conditional update scenario of PScell

[0062] The terminal device accesses the primary cell (Pcell), establishes an RRC connection, and then establishes a data radio bearer (DRB) to start data transmission. Specifically, the terminal device can establish one or more DRBs. PCell can configure dual connections for the terminal device according to the service needs of the terminal device, such as NR-DC.

[0063] In order to meet the mobility requirements, the network device configures the Conditional PSCell Addition or Change (CPAC) for the terminal device. The network device configures multiple candidate PSCells for the terminal device, which can be candidate PSCells within the secondary node (intra-Secondary Node, intra-SN) or candidate PSCells between secondary nodes (inter-SN). Each candidate PSCell has a corresponding update execution condition.

[0064] After the terminal device initially executes a PSCell update (either the network sends a command to the terminal device to execute a PSCell update, or a conditional PSCell update is executed), the terminal device continues to save the configuration of other candidate PSCells, and after the terminal device accesses a new PSCell, it can continue to execute the PSCell conditional update. For the scenario of continuous PSCell updates, because there are always candidate PSCells and corresponding update conditions on the terminal device side, if the terminal device continues to evaluate, the power consumption of the terminal device will increase.

[0065] For example, after the terminal device starts evaluating the candidate PSCell, it continues to evaluate the candidate PSCell. This may indicate that the PSCell signal to which the terminal device is connected is not very good (such as the threshold corresponding to the update condition is set low), causing the terminal device to continue to evaluate other candidate PSCells after entering this PSCell.

[0066] For another example, the terminal device intermittently evaluates the candidate PSCell after starting to evaluate the candidate PSCell, which means that the update execution conditions of the current PSCell may be set unreasonably.

[0067] To reduce the power consumption of the terminal equipment, you can perform Figure 2 Step 201 and step 202 are shown.

[0068] In the specific implementation of step 201, the terminal device records the first information.

[0069] In the specific implementation of step 202, the terminal device reports the first information.

[0070] In this embodiment, the first information includes an identifier of the currently accessed primary and secondary cells and an identifier of the first candidate primary and secondary cells, and the first candidate primary and secondary cells indicate candidate primary and secondary cells whose signal quality is lower than a first threshold.

[0071] Specifically, the first candidate primary and secondary cells include one or more of the following: candidate primary and secondary cells whose signals are not detected, candidate primary and secondary cells whose signals are detected, and candidate primary and secondary cells whose signal quality is continuously lower than a first threshold.

[0072] Specifically, when the terminal device evaluates the candidate PSCells in the currently connected PSCell, if it is found that the signals of some PSCells are always undetectable or lower than the first threshold value, it means that the settings of these PSCells are unreasonable. It is a waste of measurement resources for the terminal device to continuously evaluate these candidate PSCells in the currently connected PSCell. Therefore, the terminal device needs to record which PSCells in the candidate PSCells cannot be detected or the signal conditions are continuously lower than the first threshold value.

[0073] In addition, the terminal device can report the candidate primary and secondary cells whose signals have been detected, and the network device stores all the configured candidate primary and secondary cells on the terminal device side. Then, the network device can infer the candidate primary and secondary cells whose signals have not been detected based on the candidate primary and secondary cells whose signals have been detected.

[0074] It should be noted that the first threshold value can be set according to the actual application scenario. For example, the first threshold value is 20dbm lower than the signal threshold in the continuous condition update condition of the primary and secondary cells, or any other feasible value. This application does not impose any limitation on this.

[0075] Furthermore, the first information also includes signal quality of the first candidate primary and secondary cells.

[0076] This embodiment reports the signal quality of the first candidate primary and secondary cells, so that the network device can configure the candidate primary and secondary cells more reasonably based on the signal quality of the first candidate primary and secondary cells.

[0077] In a non-limiting embodiment, the first information also includes information on whether the candidate primary and secondary cells meet the update execution condition when the radio link fails on the secondary base station side. If not, the first information also includes the signal quality of the strongest candidate primary and secondary cells when the radio link fails.

[0078] Specifically, the update execution condition may be that the signal quality of the candidate primary and secondary cells is higher than the signal quality of the serving primary and secondary cells by a preset offset, and needs to last for a period of time, such as 80ms or 160ms. Here, satisfying the update execution condition may refer to whether the candidate primary and secondary cells meet the entry conditions set in the update execution conditions, that is, whether they are higher than the serving primary and secondary cells by a preset offset, or it may also refer to whether they are higher than the serving primary and secondary cells by a preset offset and last for a period of time.

[0079] This embodiment reports the signal quality of the strongest candidate primary and secondary cells when the radio link fails at the secondary base station side, so that the network device can configure the parameters of the radio link switching more reasonably to avoid the radio link failure.

[0080] In a non-limiting embodiment, the first information may also include one or more of the following: the first time T1 for updating the primary and secondary cells, the second time T2 for first evaluating the candidate primary and secondary cells, the time interval between the first time T1 and the second time T2, the first duration for evaluating the candidate primary and secondary cells, the second duration after the primary and secondary cells are updated, and the ratio of the first duration to the second duration.

[0081] The time interval between the first time T1 and the second time T2 can reflect how long the terminal will start evaluating the candidate PSCell again after updating the PSCell. The ratio of the first duration to the second duration can reflect the intensity of the terminal device's continuous evaluation of the candidate PSCell, which can indirectly reflect the power consumption of the terminal device.

[0082] In this embodiment, the content in the first information can further assist the network device in optimizing the configuration of the candidate primary and secondary cells.

[0083] Furthermore, the first information also includes the Nth time of evaluating the candidate primary and secondary cells for the Nth time or the time interval between the first time and the Nth time, where N is a positive integer greater than or equal to 2.

[0084] For the network device, it receives and analyzes the first information, obtains valuable results, and modifies the update conditions of the primary and secondary cells. For example, the terminal device does not need to configure some PSCells as candidate cells in certain PSCells; or it can flexibly instruct the terminal device that the candidate PSCells do not need to be evaluated in a certain PSCell (when accessing the PSCell), so that the terminal device does not need to measure the above-mentioned candidate PSCells, thereby reducing the power consumption of the terminal device.

[0085] 2. LTM continuous switching

[0086] In this embodiment, the terminal device is configured with an LTM candidate cell and a continuous LTM handover. After the terminal device performs the LTM handover and enters a new serving cell, it may need to start measuring and reporting the candidate cell. For the LTM candidate cell, the terminal device needs to continuously perform evaluation and reporting. If the terminal device continuously evaluates and reports the candidate LTM cell, a large amount of resources will be consumed.

[0087] The candidate LTM cell referred to in this embodiment may be a candidate primary cell or a candidate primary and secondary cell.

[0088] To reduce the power consumption of the terminal equipment, you can perform Figure 3 Step 301 and step 302 are shown.

[0089] In the specific implementation of step 301, the terminal device records the first information.

[0090] In the specific implementation of step 302, the terminal device reports the first information.

[0091] In this embodiment, the first information includes the identifier of the current serving cell, and also includes the signal quality, such as the channel quality indicator (CQI), and the identifier of the candidate LTM cell that is lower than the second threshold value. Specifically, in the current serving cell, when the signal quality of the candidate LTM cell continues to be lower than the second threshold value, the terminal device records the identifier of the candidate LTM cell. Alternatively, in the current serving cell, if the terminal device cannot detect the candidate LTM cell, the terminal device records the identifier of the candidate LTM cell. Specifically, the current serving cell can be the identifier of the primary cell or the identifier of the primary and secondary cells. If the candidate LTM cell is the candidate primary cell, the identifier of the current primary cell is recorded; if the candidate LTM cell is the candidate primary and secondary cell, the identifier of the current primary and secondary cells is recorded.

[0092] Furthermore, the first information may also include signal quality of the candidate LTM cell.

[0093] The network device receives and analyzes the first information, and reasonably configures the candidate LTM cells, so that the terminal device does not need to measure the candidate LTM cells, thereby reducing the power consumption of the terminal device.

[0094] In a non-limiting embodiment, the first information includes one or more of the following information in the case of access failure: failure of pre-configured resources, synchronization signal blocks SSB corresponding to the failed pre-configured resources, and channel quality of the SSB corresponding to the failed pre-configured resources.

[0095] In this embodiment, if the terminal device initiates a random access process in advance to obtain the timing advance (Timing Advance, TA) on the target side during the LTM switching process, the network device configures the terminal device with authorized resources (i.e., pre-configured resources) on the target side during the switching process. However, when the terminal device uses the authorized pre-configured resources and the specified TA to access the target cell, it is found that the signal quality of the corresponding synchronization signal block (Synchronization Signal Block, SSB) is very poor or cannot be detected, resulting in a failure to access using the pre-authorized resources. The terminal device needs to record this problem.

[0096] Specifically, the terminal device may only record the failure of the pre-configured resource. The terminal device may further record the SSB index (SSB index) corresponding to the failed pre-configured resource. The terminal device may further record the channel quality of the SSB corresponding to the failed pre-configured resource.

[0097] Furthermore, the first information includes one or more of the following: the third moment T3 when a preamble code is sent to the target cell in the process of obtaining the time advance TA of the target cell in advance, the fourth moment T4 when a switching command is received to access the target cell, and the time interval between the third moment T3 and the fourth moment T4.

[0098] In this embodiment, the terminal device reports the above information to help the auxiliary network device analyze the reasons for the failure of the pre-configured resources of the terminal device, thereby assisting the network device to optimize the candidate LTM cells, reduce unnecessary measurements of the terminal device, and reduce the power consumption of the terminal device.
