The indication response method, apparatus, terminal and storage medium provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 2, fig. 2 is a flowchart of an indication response method provided in an embodiment of the present application, where the method is applied to a terminal, and as shown in fig. 2, the method includes the following steps:

step 201, receiving a first message, where the first message includes indication information, and the indication information is used to indicate to activate or deactivate a cell.

The cell may include: and a secondary cell. Of course, this is not limited, for example: the cell may also be a primary cell in some scenarios.

Further, the cell may be one or more cells, such as one or more secondary cells.

The first message may be sent by the network device to the terminal.

Step 202, responding to the indication information at a first time;

The first time may be a subframe, a slot, a sub-slot, or a symbol, but is not limited thereto, for example: or may be a certain point in time.

The above-mentioned case that the indication information indicates to activate the cell, where the time interval between the first time and the second time is greater than or equal to the first time may be understood as responding to the indication information at a time point not earlier than the second time plus the first time;

illustratively, the first time is time slot n (which may be understood as receiving an activation indication for activating secondary cell 1 at time slot n), and the first time is equal to K time slots, then the indication information is responded (e.g., activating cell 1) no earlier than time slot n + K.

In the above case where the indication information indicates to deactivate the cell, the time interval between the first time and the second time is smaller than or equal to the first time, which may be understood as responding to the indication information at a time point that is no later than the second time plus the first time.

Illustratively, the first time is a time slot n (which may be understood as receiving an activation indication for deactivating the secondary cell 1 at the time slot n), and the first time is equal to K time slots, then the indication information is responded (e.g., deactivating the cell 1) no later than the time slot n + K.

The time for successfully transmitting the second message may be a time used for successfully transmitting the second message, for example: the time for successfully transmitting the second message may be the time between the completion of processing the first message and the successful transmission of the second message. In addition, the successful transmission of the second message may be that the terminal successfully sends the second message, or the successful transmission of the second message may be that a receiving end (e.g., a network side device) of the second message successfully receives the second message.

The first time may include a processing time of the first message and a time of successful transmission of the second message, and the first time is greater than or equal to a sum of the processing time of the first message and the time of successful transmission of the second message. The first time may be referred to as a first delay.

In this embodiment of the application, the unit of the first time may be any one of the following:

milliseconds, symbols, time slots.

Of course, this is not limited, for example: but also a subframe or a sub-slot.

In the embodiment of the application, the indication information can be responded at the first moment through the steps, so that the problem that understanding of the moment of responding the indication information by the terminal between the terminal and the network equipment is inconsistent can be avoided, and the transmission performance between the terminal and the network equipment is improved.

As an optional implementation manner, the first time is a first subframe, and the second time is a second subframe; or,

the first moment is a first time slot, and the second moment is a second time slot; or,

the first time is a first symbol, and the second time is a second symbol.

Optionally, the first time is determined according to a converted subframe after the first time is converted into the subframe; or

The first moment is determined according to the converted time slot after the first time is converted into the time slot; or

The first time is determined according to the converted symbol after the first time is converted into the symbol.

The first time may be determined according to the converted sub-frame after the first time is converted into the sub-frame, and before the first time is determined, the first time may be converted into the sub-frame, for example, the unit of the first time is millisecond, for example, 2 milliseconds, and the first time may be actually understood as how many sub-frames the first time is equivalent to, for example, 2 milliseconds equivalent to 2 sub-frames, and then determined according to the converted sub-frame.

The first time conversion into time slots and the first time conversion into symbols are the same, and are not described herein again.

Further, the first time may be converted when the unit of the first time does not coincide with the unit of the second time.

For example: when the first time is a first subframe and the second time is a second subframe, the first time is determined according to the converted subframe after the first time is converted into the subframe; or

Under the condition that the first moment is a first time slot and the first moment is a second time slot, the first moment is determined according to the converted time slot after the first time is converted into the time slot;

and when the first time is a first symbol and the second time is a second symbol, the first time is determined according to the converted symbol after the first time is converted into the symbol.

Optionally, the converting the first time into a subframe or a symbol or a slot includes:

converting the first time into a subframe or a symbol or a slot with reference to a subcarrier spacing of a physical resource transmitting the second message.

The converting the first time into the subframe, the symbol, or the time slot may be performed by determining the number of the subframe, the symbol, or the time slot equivalent to the first time according to the inter-subcarrier interval, with reference to the subcarrier interval of the physical resource for transmitting the second message.

It should be noted that, since the subcarrier intervals are different, the number of slots or symbols included in a unit millisecond is different, and therefore, the first time needs to be converted. For example, if the unit of the first time is milliseconds, the first time needs to be converted into a time slot or a symbol number to determine the position of the second time. In order to ensure that the terminal and the network side device keep consistent understanding of the position of the second time, the subcarrier interval used as a reference needs to be selected. The reference subcarrier spacing may be a subcarrier spacing of a physical resource (e.g., an uplink grant) for transmitting the second message, or may be a protocol convention.

As an optional implementation manner, the second time is any one of the following:

a start time or an end time of transmission of the first message on a first physical channel;

a start time or an end time of a transmission of a last segment of the first message on a first physical channel;

and the overtime moment of the timer corresponding to the cell.

The first Physical channel may be a downlink Physical shared channel (PDSCH). For example: the indication information is carried by a Radio Resource Control (RRC) message, and the second time is a start time or an end time when the PDSCH including the RRC message (or including the last segment of the RRC message) is received; another example is: if the indication information is carried by a Medium access control element (MAC CE), the second time is a start time or an end time when the PDSCH including the MAC CE is received.

The last segment of the first message may be that the first message contains the last segment in the order of segments, for example: the first message is divided into segment 1, segment 2 and segment 3 in sequence, and the last segment mentioned above may refer to segment 3 including the first message. Alternatively, the last segment of the first message may be that the first message includes the last segment in the receiving order of the plurality of segments, for example: the first message is divided into segment 1, segment 2 and segment 3 in sequence, and the last segment may refer to the last received segment, e.g., the terminal receives segments 1, 3 and 2 in sequence, and segment 2 is the last segment.

The Timer may be a Deactivation Timer (Deactivation Timer), and if the cell is a secondary cell, the Timer is a Deactivation Timer (SCellDeactivationTimer) corresponding to the secondary cell.

As an optional implementation manner, in a case that the first message is a Medium access control element (MAC CE), the second message is feedback information (such as HARQ feedback information, which may be understood as HARQ feedback information received for a PDSCH including the MAC CE) received for a first physical channel; or

In a case that the first message is a Radio Resource Control (RRC) message, the second message is an RRC response message; or

In the case that the first message is a radio resource control RRC message, the second message is feedback information received for a first physical channel (e.g. HARQ feedback information, which may be understood as HARQ feedback information received for a PDSCH including the RRC message).

The RRC message may be an RRC Reconfiguration message (RRC Reconfiguration message), and the second message may be an RRC Connection Reconfiguration Complete message (RRC Connection Reconfiguration Complete); alternatively, the RRC message may be an RRC recovery message (RRC Resume message), and the second message may be an RRC recovery Complete message (RRC Resume Complete message).

As an optional implementation manner, the time when the second message is successfully transmitted is a time corresponding to any one of the following:

receiving first scheduling information;

the second message begins transmission on a second physical channel;

the last segment of the second message begins transmission on a second physical channel;

the second message ends transmission on a second physical channel;

the last segment of the second message ends transmission on a second physical channel;

receiving a first status report indicating that the second message was successfully received;

receiving a second status report indicating that a last segment of the second message was successfully received;

and the first scheduling information is used for indicating a first process transmitting the second message to perform new transmission.

The second physical channel may include any one of the following:

an uplink physical control channel PUCCH or an uplink physical shared channel PUSCH.

The first status report or the second status report may include:

a Radio Link Control (RLC) status report or a Packet Data Convergence Protocol (PDCP) report.

For example: the first status report is an RLC status report or a PDCP report, and the second status report is an RLC status report or a PDCP report.

The first scheduling information is used to indicate that the first process transmitting the second message performs new transmission, where the network device schedules, through the first scheduling information, the terminal to perform new transmission in the first process of the second message, which indicates that the second message is successfully transmitted. The first process may be a Hybrid Automatic Repeat Request (HARQ) process. For example, the second message is sent through an HARQ process with an HARQ process number of 1 (for example, HARQ process ID ═ 1), and the first scheduling information on the network side is subsequently received, where the scheduling information indicates that a first process (the first process is an HARQ process with an HARQ process ID of 1) transmitting the second message is newly transmitted, and then the terminal device considers that the network-side device has successfully received the second message, which can be understood as that the terminal has successfully transmitted the second message.

Optionally, the second message starts to be transmitted on a second physical channel, and the second message includes any one of the following items:

the second message begins transmission on a second physical channel before the first scheduling information is received;

the second message begins transmission on a second physical channel before receiving the first status report or the second status report;

and/or the presence of a gas in the gas,

the last segment of the second message begins transmission on a second physical channel, comprising any of:

starting transmission of a last segment of the second message on a second physical channel before receiving the first scheduling information;

starting transmission of a last segment of the second message on a second physical channel prior to receiving the first status report or the second status report;

and/or the presence of a gas in the gas,

the second message ending transmission on a second physical channel, comprising any of:

before receiving the first scheduling information, the second message finishes transmission on a second physical channel;

the second message ends transmission on a second physical channel before receiving the first status report or the second status report;

and/or the presence of a gas in the gas,

the last segment of the second message ending transmission on a second physical channel, comprising:

before receiving the first scheduling information, the last segment of the second message finishes transmission on a second physical channel;

the last segment of the second message ends transmission on a second physical channel before receiving the first status report or the second status report.

Further, before receiving the first scheduling information, the second message starts to be transmitted on a second physical channel, including:

before receiving the first scheduling information, the second message starts to be transmitted on a second physical channel for the first time or the last time; and/or the presence of a gas in the gas,

before the receiving the first scheduling information, a last segment of the second message starts to be transmitted on a second physical channel, including:

before receiving the first scheduling information, the last segment of the second message starts to be transmitted on a second physical channel for the first time or the last time; and/or the presence of a gas in the gas,

before the receiving the first scheduling information, the second message ends transmission on a second physical channel, including:

before the first scheduling information is received, the second message finishes transmission on a second physical channel for the first time or the last time; and/or the presence of a gas in the gas,

before the receiving the first scheduling information, ending transmission of a last segment of the second message on a second physical channel, comprising:

before receiving the first scheduling information, the last segment of the second message finishes transmission on a second physical channel for the first time or the last time; and/or the presence of a gas in the gas,

the second message begins transmission on a second physical channel before the first status report or the second status report is received, comprising:

starting transmission of the second message on a second physical channel for the first time or the last time before receiving the first status report or the second status report; and/or the presence of a gas in the gas,

the receiving a second status report, wherein the second status report includes a second segment of the second message transmitted on a second physical channel, the second segment including:

starting transmission of a last segment of the second message on a second physical channel for a first or last time before receiving the first status report or the second status report; and/or the presence of a gas in the gas,

before the receiving of the first status report or the second status report, the second message ending transmission on a second physical channel, including:

before receiving the first status report or the second status report, the second message finishes transmission on a second physical channel for the first time or the last time; and/or the presence of a gas in the gas,

the ending transmission of the last segment of the second message on a second physical channel before the receiving of the first status report or the second status report comprises:

the last segment of the second message ends transmission on a second physical channel for the first or last time before receiving the first status report or the second status report.

The first time the second message starts to be transmitted on the second physical channel may be, before the first scheduling information is received, the first time the second message starts to be transmitted on the second physical channel, and the last time the second message starts to be transmitted on the second physical channel may be, before the first scheduling information is received, the last time the second message starts to be transmitted on the second physical channel. The same process for the first time, the last time and the end of transmission is not described herein.

As an optional implementation manner, in the case that the indication information indicates to activate the cell, the responding to the indication information includes:

activating the cell.

In this embodiment, it may be achieved that the cell is activated at a time point not earlier than the second time plus the first time.

Optionally, the method further includes:

and activating a timer corresponding to the cell.

Such as activating the SCellDeactivationTimer corresponding to the secondary cell.

Optionally, a time interval between the time of activating the timer corresponding to the cell and the second time is equal to the first time.

Illustratively, the first time is a time slot n (which may be understood as receiving an activation indication for activating the secondary cell 1 at the time slot n), and the first time is equal to K time slot lengths, then the indication information is responded to at the time slot n + K (e.g. activating a corresponding timer of the cell 1).

In this embodiment, the timer corresponding to the cell is activated at the time point of the second time plus the first time. Therefore, the terminal and the network equipment can guarantee the understanding consistency of the time for activating the timer corresponding to the cell.

Of course, in the embodiment of the present application, the timer corresponding to the cell may not be activated.

Illustratively, when receiving an RRC message indicating activation of the secondary cell 1, the terminal activates the secondary cell 1 at the first time, but does not activate the timer corresponding to the secondary cell 1.

As an optional implementation manner, in a case that the indication information indicates to deactivate the cell, the responding to the indication information includes:

deactivating the cell.

In this embodiment, it may be achieved that the cell is deactivated at a time point not later than the second time plus the first time.

Optionally, the method further includes:

deactivating the timer corresponding to the cell at a third time,

the third time is the second time, or the third time is a time corresponding to a second time after the second time, where the second time includes the processing time of the first message.

The third time may be a time corresponding to a second time after the second time, and a time interval between the third time and the second time may be equal to the second time.

The second time may include a processing time of the first message, and the second time is equal to the processing time of the first message, or the second time is equal to the processing time of the first message plus a predefined time.

Illustratively, the first time is a time slot n (which may be understood as receiving an activation indication for activating the secondary cell 1 at the time slot n), the first time is equal to K time slots, and the predefined time is M time slots, then the indication information is responded to at the time slot n + K + M (e.g. activating a corresponding timer of the cell 1). Where M may be equal to zero or 1, or other integer value.

This embodiment may be implemented, where the terminal and the network device guarantee that the understanding is consistent for the time when the timer corresponding to the cell is deactivated.

As an optional implementation, the first time further includes: a predetermined defined time, and the first time is equal to the sum of:

the processing time of the first message, the time of successful transmission of the second message and a predetermined defined time.

The predetermined defined time may be a protocol agreement or a network preconfiguration, and the unit may be a subframe, a slot, a symbol, or the like.

This embodiment may enable activation of the cell not earlier than the point in time, and may also enable deactivation of the cell not later than the point in time, which is the second time plus the sum of the three terms.

For example: taking the second time as T, the sum of the processing time of the first message and the time of successful transmission of the second message as T1, and the predetermined defined time as N, for example, it may be implemented that the cell is activated no earlier than time T + T1+ N, or a timer corresponding to the cell is activated at time T + T1+ N, or the cell is deactivated no later than time T + T1+ N.

As an optional implementation manner, in a handover scenario, the first time further includes a predefined time and a handover interruption time, and the first time is equal to the sum of the following four terms:

the processing time of the first message, the time of successful transmission of the second message, the predetermined defined time and the handover interruption time.

The handover scenario may be a cell handover scenario, for example: the activation or deactivation of a cell is performed during a cell handover procedure.

The above-mentioned switching interruption time may be a fixed time defined in advance, or a considerable time determined according to scene information of a terminal switching scene.

In this embodiment, because the handover interruption time is added, the problem that the terminal and the network device have inconsistent understanding of the time for responding to the indication information due to handover interruption in the handover scene can be avoided.

Referring to fig. 3, fig. 3 is a cell deactivation method provided in the embodiment of the present application, and is applied to a terminal device, as shown in fig. 3, including the following steps:

step 301, determining a deactivated cell.

The determining to deactivate the cell may be determining to deactivate the cell when a timer corresponding to the cell is overtime. The cell may include a secondary cell. It may be understood that the second time is a time when a timer corresponding to the cell expires.

Step 302, responding to and deactivating the cell at a first time;

the time interval between the first time and the second time is less than or equal to a first time, the second time is a time when a timer corresponding to the cell times out, the first time includes a processing time of a first message and a time when a second message is successfully transmitted, and the second message is a response message of the first message.

The processing time of the first message and the time of successful transmission of the second message may be preset or assumed. For example, the first time may be determined based on a time used for the terminal device to receive a previous (e.g. last) indication to activate or deactivate the cell through an RRC message or a MAC CE, for example, the terminal receives a MAC CE signaling indication to activate the secondary cell last time, and a total time for the terminal to process the first message including the MAC CE information and the response message of successfully transmitting the first message is T. And when the timer corresponding to the auxiliary cell is overtime, the terminal equipment deactivates the cell within the time delay T. For example, when the time when the timer corresponding to the secondary cell times out is the time slot n, the terminal deactivates the cell no later than the time slot n + T/(the time slot length). The first message may be an RRC message or a MAC CE, and the RRC message or the MAC CE may be a message for indicating activation or deactivation of the cell. It should be noted that, in this embodiment, the terminal is not limited to receive the first message and transmit the second message, and the time corresponding to the two messages may be preset or assumed by the terminal.

It should be noted that, for the first time, the processing time of the first message, the time of successfully transmitting the second message, and the like, reference may be made to the corresponding description of the embodiment shown in fig. 2, which is not described herein again.

In this embodiment, through the above steps, the problem of inconsistent understanding between the terminal and the network device at the time when the terminal deactivates the cell can be solved, so as to improve the transmission performance between the terminal and the network device.

The method provided by the embodiment of the present application is illustrated by taking a cell as a secondary cell as an example through two embodiments:

the first embodiment is as follows:

in this embodiment, the indicating, by the network side, to activate the secondary cell may include the following:

step 1: the terminal receives indication information for activating the secondary cell, where a time point when the terminal receives the indication information is T (i.e., the second time), and a unit of T may be a time slot or a symbol, for example, the indication information is received in the time slot T.

If the indication information for activating the secondary cell is carried by an RRC message, the time point T is a start time or an end time when the PDSCH including the RRC message (or including the last segment of the RRC message) is received;

if the indication information for activating the secondary cell is carried by the MAC CE, the time point T is a start time or an end time when the PDSCH including the MAC CE is received.

Step 2: the terminal executes a specific operation according to a timing relationship agreed by a protocol or configured by a network, and specifically includes the following two schemes:

the first scheme is as follows: if the indication information for activating the secondary cell is carried by an RRC message, performing the following specific operations:

activating a timer corresponding to the secondary cell at a time point T + T1+ N (the unit may be a time slot or a symbol); or, not activating the timer corresponding to the secondary cell;

activating the secondary cell no earlier than a time point T + T1+ N (the unit may be a time slot or a symbol);

the T1 includes the processing time of the RRC message, and the time when the terminal successfully transmits the RRC response message (i.e., the second message), for example, T1 ═ TRRCprocess + trrccomplex. The N is a predetermined defined time appointed by the protocol, and can be zero or non-zero time;

in addition, the terminal determines successful transmission of the RRC response message based on any one of:

receiving first scheduling information (such as DCI), wherein the first scheduling information indicates the HARQ process transmitting the RRC response message to perform new transmission.
