Detailed Description

As described above, in the 5G high frequency deployment scenario, the UE is easy to frequently perform a cell handover (e.g. L1 or L2 handover) procedure, and a cell reestablishment procedure after the cell handover procedure fails, which may cause interruption of data transmission of the UE, thereby affecting the service experience of the UE. To cope with this problem, introduction of a handover enhancement mechanism based on L1 or L2 is being considered; namely, the source base station configures RRC configuration information of a plurality of candidate cells for the terminal, and then sends a medium access Control-Control element (MAC CE, medium access Control-Control element) or downlink Control information (DCI, downlink Control Information) activation command to the terminal according to the synchronization Signal of L1 and the measurement result of the beam of a PBCH block (SSB, synchronization Signal and PBCH block) and/or a channel state information Reference Signal (CSI-RS, channel State Information-Reference Signal) reported by the terminal, so that the terminal activates RRC configuration of the corresponding candidate cell according to the activation command, that is, initiates a handover procedure to the candidate cell. In this way, based on the L1 or L2 handover of DCI or MAC CE, the time for the terminal to perform L3 filtering on the measurement result can be saved, the time required for the source base station and the target base station to perform negotiation of the handover preparation process and the resource preparation process can be saved, and the time for the source base station to change the handover command sent by the source base station to the UE from RRC message to DCI or MAC CE can also be saved by several tens of milliseconds (ms).

However, considering that since the L1 or L2 handover mechanism is performed based on the measurement result of L1 of the UE, and the measurement result of L1 changes rapidly, the UE performs handover based on the measurement result of L1, it is likely that an RRC connection cannot be successfully established with the target cell (i.e., handover failure) or that a radio link failure (RLF, radio Link Failure) occurs in the target cell soon after the RRC connection is established, i.e., early handover. According to the existing working mechanism, when the UE fails to switch or switches too early, a reestablishment process is carried out, namely the UE executes cell selection and tries to access to the selected cell, and then the selected cell acquires the context information of the UE from the previous service cell; if the UE performs reconstruction frequently, the data transmission of the UE is interrupted, and the service experience of the UE is affected.

Based on this, the embodiment of the invention provides a cell activation method, and a terminal determines at least one candidate cell; the at least one candidate cell comprises: the network device activates a first candidate cell in the at least one candidate cell for the cell for L1 or L2 handover configured by the terminal and/or the cell detected by the terminal as being available for L1 or L2 handover. Correspondingly, the network equipment sends first information to the terminal; the first information is used to indicate at least one candidate cell configured for a terminal by the network device for L1 or L2 handover. Therefore, the terminal can be directly connected with the candidate cell which is preconfigured by the network equipment or detected by the terminal without executing the reestablishment flow, so that the frequent reestablishment of the terminal is avoided, the interruption of data transmission is reduced, the influence on the service experience of the terminal is reduced, and the service experience of the terminal is further improved.

The present invention will be described in further detail with reference to examples.

Fig. 1 is a schematic flow chart of a cell activation method according to an embodiment of the present invention; as shown in fig. 1, the method may be applied to a Terminal, which may also be referred to as a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (Mobile Terminal), or the like, which may communicate with one or more core networks via a radio access network, and which may be a portable, pocket, hand-held, computer-built-in, or vehicle-mounted Mobile device, such as a Mobile phone, a smart phone, a notebook, a digital broadcast receiver, a Personal Digital Assistant (PDA), a tablet (PAD), a Portable Multimedia Player (PMP), a wearable device (such as a smart bracelet, a smart watch, or the like), a navigation device, or the like. The method comprises the following steps:

step 101, determining at least one candidate cell; the at least one candidate cell comprises: the network equipment configures a cell for L1 or L2 switching for the terminal, and/or the cell which is detected by the terminal and can be used for L1 or L2 switching;

step 102, activating a first candidate cell of the at least one candidate cell.

In the embodiment of the present invention, activating a corresponding candidate cell (e.g., a first candidate cell) may also be described as switching to the candidate cell, or may also be described as establishing physical layer connection with the candidate cell, establishing RRC connection with the candidate cell, connecting to the candidate cell, etc., which may be understood as the terminal performing data transmission or communication through the candidate cell; the embodiment of the invention is not limited to the description mode. The candidate cells may be activated by initiating a random access procedure, and the method of activation is not limited herein.

The L1 or L2 handover may also be described as including, but not limited to, any of the following: l1 or L2 activation, L1 cell activation, DCI-based cell activation, L2 cell activation, MAC CE-based cell activation, L1 or DCI-based cell activation, L2 or DCI-based cell activation, cross-cell beam management, etc.; the embodiment of the invention is not limited to the description mode.

Here, the target cell may be a cell that is determined to be activated by the network device (i.e. the source base station) according to the measurement result of the L1 beam reported by the terminal. The network device may inform the terminal by sending a MAC CE or DCI to the terminal, which may carry: information indicating relevant information such as identification of the target cell, configuration information of the target cell, and the like.

The terminal initiates a switching process to the target cell by using the configuration information of the target cell, but the switching is unsuccessful (for example, the terminal does not receive an RRC establishment (Setup) command sent by a corresponding base station), or the terminal quickly generates connection failure (for example, RLF) in the target cell after the switching is successful; in this case, the terminal attempts to activate a first candidate cell of the at least one candidate cell.

The terminal may also attempt to activate a first candidate cell of the at least one candidate cell after receiving the first command; here, the first command is used to instruct the terminal to activate the candidate cell or switch to the candidate cell, and may also be understood as instructing the terminal to establish a physical layer connection or RRC connection with the candidate cell or connect to the candidate cell, etc. That is, the network device may also actively trigger the terminal to activate the first candidate cell.

In some embodiments, the determining at least one candidate cell includes at least one of:

receiving first information from a network device; the first information is used for indicating a cell of L1 or L2 switching configured by the network equipment for the terminal;

cells available for L1 or L2 handover are detected.

Here, the first information may specifically include: the configuration information comprises an index of at least one candidate cell, RRC (radio resource control) of each candidate cell in the at least one candidate cell and the like;

the index of the candidate cell may be an identity of the cell, such as a physical cell identity (PCI, physical Cell Identity), an NR network global cell identity (NCGI, NR Cell Global Identifier), etc.;

the configuration information is used for the terminal to perform cell activation, and may include: a random access resource or a Cell-radio network temporary identifier (C-RNTI).

For example, the first information may include: the identification of the cell 1, the random access resource configured by the cell 1 for the terminal, and/or the C-RNTI; the identification of the cell 2, the random access resource configured by the cell 2 for the terminal, and/or the C-RNTI; … … identity of cell n, random access resources configured by cell n to the terminal, and/or C-RNTI.

The candidate cell may be a cell to which the terminal itself can connect (i.e., a cell available for L1 or L2 handover) determined by the detection; the candidate cells may also be configured by a source cell to which the terminal is connected, and configuration information related to L1 or L2 handover of one or more candidate cells may be determined by the network device (i.e., the source base station) and then sent to the terminal.

Here, the network device may be a base station of a source cell to which the terminal is connected, i.e., a source base station. The terminal receives one or more configuration information (i.e. the first information) related to the L1 or L2 handover sent by the source base station, determines one or more cells for the L1 or L2 handover as candidate cells, and then, the terminal may select one candidate cell from the at least one candidate cell for activation according to a measurement result of the at least one candidate cell.

The terminal may also actively detect a cell connectable to itself (i.e. a cell available for L1 or L2 handover), take the detected cell as a candidate cell, and then select one candidate cell from at least one candidate cell for activation according to the measurement result of the detected cell connectable to itself and/or the measurement result of the cell indicated by the first information.

In some embodiments, the at least one candidate cell further comprises: a source cell.

That is, the candidate cell may be a source cell to which the terminal is connected, other cells configured by the source base station, or other cells detected by the terminal itself.

When the terminal fails in handover or is switched too early, the terminal does not execute the reestablishment flow, but tries to recover the connection with the source cell or tries to switch to another candidate cell, so as to avoid frequent reestablishment of the terminal, thereby reducing interruption of data transmission and not affecting the service experience of the terminal.

In some embodiments, the measurement comprises at least one of the following measurements: RSRP, RSRQ, SINR;

and determining a candidate cell with the optimal measurement result in the at least one candidate cell as the first candidate cell. Here, the measurement result is optimal to characterize the communication quality as optimal, e.g., RSRQ is greater than the RSRQ threshold and RSRQ is maximum.

In practical application, the network device (such as the source base station) may configure, in advance, conditions for selecting candidate cells for the terminal, for example, a threshold value corresponding to the measured value is sent to the terminal: RSRP threshold, RSRQ value, SINR threshold.

Based on this, in some embodiments, the method may further comprise:

and receiving second information sent by the network equipment, wherein the second information is used for indicating a threshold value for activating the candidate cell.

Wherein the threshold value comprises at least one of: RSRP threshold, RSRQ threshold, SINR threshold.

Here, the measurement result may also be described as an L1 measurement result at a cell level, an SSB of L1, or a measurement result of a channel state information Reference Signal (CSI-RS, channel State Information-Reference Signal), or the like; the manner of description is not limited herein.

Accordingly, the threshold may be a threshold at a cell level, or may be a threshold at a beam level (such as SSB or CSI-RS), which is not limited herein.

Specifically, the measurement may include at least one of: RSRP, RSRQ, SINR; and the terminal compares the determined measured value with a threshold value corresponding to the measured value, and selects any one from the candidate cells of which the measured value exceeds the corresponding threshold value for activation, namely, the terminal can activate only if the measured value exceeds the corresponding threshold value.

The threshold value used by each candidate cell may be the same or different, i.e., may be configured for each (per) candidate cell individually.

The terminal can select a candidate cell with the best measurement result according to the measurement result and initiate a random access flow; or under the condition that the measurement results of the plurality of candidate cells meet the threshold requirement, the terminal randomly selects one candidate cell to initiate a random access flow.

In some embodiments, in case the terminal does not successfully activate the first candidate cell, the method further comprises:

Wherein the second condition includes at least one of:

the terminal activates candidate cells;

The terminal fails to activate both of the at least two candidate cells;

the terminal fails to connect; the terminal failure comprises: RLF occurs at the terminal (also may be described as terminal claim RLF).

Here, the terminal activates the candidate cell, i.e. the terminal switches to the candidate cell, i.e. the terminal successfully establishes a connection with the candidate cell, such as RRC connection, physical layer connection.

The terminal generates RLF (or the terminal declares RLF), including at least one of:

wherein the terminal satisfying the third condition includes at least one of:

the first moment is one of the following:

the moment when the terminal receives a first command from the network device;

The terminal does not successfully activate the candidate cells (e.g., the first candidate cell, the second candidate cell), i.e., the terminal does not successfully establish a connection (e.g., RRC connection, physical layer connection) with the second candidate cell, or fails (e.g., RLF) soon after the connection is established (e.g., within a period of time).

It should be noted that, based on the measurement result of at least one candidate cell, the above method determines that candidate cells (such as the first candidate cell, the second candidate cell, and the third candidate cell) from the at least one candidate cell are all: a candidate cell is determined from at least one candidate cell based at least on a measurement of the at least one candidate cell. That is, in practical application, the candidate cell may be selected for activation in combination with the measurement result of at least one candidate cell and other information. For example, the network device may configure a priority for each candidate cell and inform the terminal that the terminal may select in combination with the measurement result and the priority of at least one candidate cell; for another example, the terminal may determine a location relationship (such as a cell edge, a cell center, etc.) with each candidate cell, and select in combination with a location distance, etc.

In some embodiments, the method further comprises at least one of:

the terminal starts to count from the first moment, and if the count length of the timer is greater than or equal to a third threshold (also can be described as expiration of the timer) and the terminal does not successfully establish connection with the network, the terminal generates RLF;

wherein the terminal satisfying the third condition includes at least one of:

the target time is one of the following:

the moment (or point in time) when the terminal receives the first command from the network device;

Specifically, the terminal may start from receiving the first command of the source base station, or start according to the handover failure performed by the first command of the source base station, or start the terminal to autonomously activate the candidate cell for the first time, start the timer, expire the timer, or reach the maximum number when the number or the number of the candidate cells that the terminal autonomously tries to activate or activate reaches, and the terminal still fails to establish a connection with the network, and declare RLF.

Here, the terminal does not successfully establish a connection with the network, which can also be understood as that the terminal does not successfully activate any candidate cell; or, not connected to any one candidate cell; or, the terminal does not establish a physical layer connection or an RRC connection with any one of the candidate cells.

In practical applications, the network device (i.e. the source base station) may configure the terminal with the maximum number or maximum number of candidate cells that the terminal autonomously tries to activate or activates, or the maximum time length for which activation is attempted.

Based on this, in some embodiments, the method further comprises:

In actual application, the terminal can inform the network device of the information of itself attempting to autonomously activate the candidate cell.

Based on this, in some embodiments, the method further comprises:

Sending a report to the network device; the report includes at least one of:

attempting activation or identification of activated candidate cells;

indication information; the indication information is used for indicating the candidate cells which are attempted to be activated or activated to be cells of a first type or cells of a second type; the first type of cells are cells configured by the network equipment for the terminal and used for L1 or L2 switching, and the second type of cells are cells detected by the terminal and used for L1 or L2 switching;

a first number of candidate cells attempting to activate or activate;

a first number of attempts to activate or activate a candidate cell;

attempting to activate or activate a second number of the first type of cells;

a ratio of the first number to the second number;

a second number of attempts to activate or activate the first type of cell;

a ratio of the second number to the first number;

attempting to activate or activate a third number of the second class of cells;

a ratio of the third number to the first number;

a third number of attempts to activate or activate the second class of cells;

a ratio of the third number of times to the first number of times;

a ratio of the second number to the third number;

A ratio of the second number to the third number;

attempting an activation or measurement of an activated candidate cell;

the moment when the terminal receives a first command from the network device;

Here, the indication information may include at least one of:

the candidate cells attempting to activate or activate are cells of a first type (i.e., cells configured by the network device for the terminal for L1 or L2 handover), or cells of a second type (i.e., cells detected by the terminal as being available for L1 or L2 handover);

Whether the candidate cell attempting activation or activation is a first type cell (i.e., a cell configured by the network device for L1 or L2 handover for the terminal);

whether the candidate cell attempting activation or activation is a second type of cell (a cell detected by the terminal as being available for L1 or L2 handover).

The indication information can also be characterized by other characters or numbers or symbols, for example, the indication information comprises a number 1, which indicates that the candidate cell which is attempted to be activated or activated is a first type cell; the indication information includes a number of 2, indicating that the candidate cell attempting to be activated or activated is a second type cell.

The ratio of the first number to the second number is used to describe the ratio of the cells configured by the network device for the terminal for L1 or L2 handover (i.e. the first type cells) in the candidate cells attempting activation or activation. The specific steps can be as follows: a second number/first number; wherein first number = second number + third number.

The ratio of the second number to the first number is used for explaining the number of times the terminal tries to activate or activate the cell (i.e. the first type cell) configured by the network equipment for the terminal for L1 or L2 handover among the number of times the candidate cell tries to activate or activate. The specific steps can be as follows: second number/first number; wherein first number of times = second number of times + third number of times;

The ratio of the third number to the first number is used to describe the ratio of the cells detected by the terminal as being available for L1 or L2 handover (i.e. the second type of cells) among the candidate cells attempting to activate or active. The specific steps can be as follows: a third number/first number; wherein first number = second number + third number.

The ratio of the third number to the first number is used for describing the number of times the terminal tries to activate or activate the cell which is detected by the terminal and can be used for L1 or L2 switching (namely, the second type cell) among the number of times the candidate cell tries to activate or activate. The specific steps can be as follows: third number/first number; wherein first number of times = second number of times + third number of times;

the ratio of the second number to the third number is used for describing the ratio of the number of the first type of cells which are attempted to be activated or activated to the number of the second type of cells which are attempted to be activated or activated. The specific steps can be as follows: a second number/third number; alternatively, the third number/second number may be used.

The ratio of the second times to the third times is used for describing the ratio of the times of the first type of cells which are attempted to be activated or activated to the times of the second type of cells which are attempted to be activated or activated. The specific steps can be as follows: second/third times; alternatively, the third number/second number may be used.

The terminal activates the candidate cell successfully, i.e. the terminal is successfully switched to the candidate cell, i.e. the terminal successfully establishes a connection with the candidate cell, such as an RRC connection, a physical layer connection.

In practical application, considering that the terminal has not successfully activated any candidate cell until RLF occurs, there may be incorrect values (such as a first threshold, a second threshold, a threshold, etc.) configured by the network device, and therefore, in order to improve the success rate of activating the candidate cell, a method for adjusting the corresponding values is provided.

Based on this, in some embodiments, the method further comprises:

an adjusted RSRP threshold;

an adjusted RSRQ threshold;

an adjusted SINR threshold value;

Here, the fourth information may be that the network device reconfigures based on a report transmitted from the terminal and transmits to the terminal.

In particular, the terminal may record information of autonomous activation candidate cells by the terminal in a report (such as an RLF report or other report), including at least one of: attempting activation or identification information associated with activated candidate cells; the number of candidate cells for attempting to activate or activating, the maximum number or the maximum number of candidate cells for autonomous attempting to activate or activating are allowed by the terminal configured by the network side; autonomous attempt to activate or measurement of candidate cells at activation; a measurement result is compared with a threshold value to obtain a exceeding part value or proportion; the terminal starts switching failure according to the command of the source base station, or starts the candidate target cell for the first time, and the time difference information (namely the time length for trying to activate or activate the candidate cell) from the successful switching of the terminal to the declaration of RLF. The network device (source base station) can judge whether the configured candidate cell, the threshold (such as a first threshold, a second threshold and a third threshold) and the threshold (such as an RSRP threshold, an RSRQ threshold and an SINR threshold) corresponding to each measured value are suitable according to the information reported by the terminal.

For example, if the measurement result of the terminal exceeds the configured threshold value but still fails to switch, it may indicate that the threshold value is configured to be lower and needs to be increased;

for another example, the network device (source base station) may determine, according to the information about the duration of attempting to activate or activate the candidate cell, whether the maximum duration (i.e., the third threshold) of the candidate cell allowed to be activated or activated, which is configured for the terminal, is appropriate, and if the time required for most terminals to succeed in handover is shorter, it means that the third threshold may be configured to be shorter; if the time required for most terminals to handover successfully is longer, this means that the third threshold needs to be configured longer;

the network device (source base station) may determine, according to the maximum number and/or maximum number of candidate cells attempting to activate or activated, whether the maximum number and/or maximum number of candidate cells allowed to activate (i.e. the first threshold and/or the second threshold) configured for the terminal is appropriate, if most terminals have fewer candidate cells attempted until the handover is successful, this means that the first threshold may be configured to be smaller; if most terminals try more candidate cells until the handover is successful, this means that the first threshold needs to be configured to be larger; similarly, if the number of times that most terminals attempt to activate candidate cells until a handover is successful is small, this means that the second threshold can be configured to be small; if most terminals attempt to activate the candidate cell more times until the handover is successful, this means that the second threshold needs to be configured larger.

The first threshold, the second threshold and the threshold may be adjusted by comprehensively referencing the measurement results of the candidate cells for activation attempted sent by one or more terminals, and the value or proportion of the measurement results of the candidate cells for activation attempted to the exceeding part of the threshold. If the measurement results of a large number of terminals exceed the threshold by a large amount or exceed a large proportion, the threshold value can be adjusted up by a small amount; conversely, the threshold value may be adjusted downward.

In the embodiment of the invention, the candidate cell activated by the terminal and the service cell currently connected by the terminal may be the same base station or may be different base stations. The method for activating the candidate cell by the terminal may use a random access procedure, and specific steps are not limited herein.

The method comprises the following steps:

The first information may specifically include: the configuration information comprises an index of at least one candidate cell, RRC (radio resource control) of each candidate cell in the at least one candidate cell and the like;

Here, when the terminal fails in handover or switches too early, the terminal does not execute the reestablishment procedure, but tries to recover the connection with the source cell or tries to switch to a candidate cell configured by the network device for the terminal, so as to avoid frequent reestablishment of the terminal, thereby reducing interruption of data transmission and not affecting service experience of the terminal.

In practical application, the network device (i.e. the source base station) may configure the conditions for selecting the candidate cells for the terminal in advance, for example, send the threshold values corresponding to various measured values to the terminal: RSRP threshold, RSRQ value, SINR threshold.

In some embodiments, the method further comprises:

sending second information to the terminal; the second information is used for indicating a threshold value for activating the candidate cell;

The threshold may be a threshold at a cell level, or may be a threshold at a beam level (e.g., SSB or CSI-RS), which is not limited herein.

It should be noted that the threshold value adopted by each candidate cell may be the same or different, that is, the threshold value adopted by each candidate cell may be configured separately for each candidate cell.

In practical applications, the network device (i.e. the source base station) may configure the terminal with the maximum number or number of candidate cells that the terminal autonomously tries to activate or activates, or the maximum time length for which activation is attempted.

Therefore, frequent reconstruction of the terminal is avoided, interruption of data transmission is reduced, influence on service experience of the terminal is reduced, and service experience of the terminal is further improved. The method provided by the embodiment of the invention is particularly suitable for small cells deployed at high frequency or high-speed moving scenes with frequent switching
