Therefore, how to accurately determine whether a cell enters an activation phase or an inactivation phase of discontinuous transmission and/or reception so as to save network power in a timely manner and transmit the data to be sent as much as possible has become a technical problem that needs to be solved urgently.

In order to accurately determine whether a cell enters an activation phase or an inactivation phase of discontinuous transmission and/or reception, the embodiments of the present disclosure provide a communication method, device, and apparatus. The method, the apparatus, and the apparatus are based on the same application concept, and since the method and the apparatus solve the problem in a similar principle, the implementation of the apparatus and the method can refer to each other, and the repeated parts will not be repeated.

The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

FIG1 is one of the flow charts of the communication method provided by the embodiment of the present disclosure. The communication method shown in FIG1 may be performed by a terminal device or a communication device provided in the terminal device, and the communication device may be composed of software and/or hardware. As shown in FIG1 , the method includes:

Step 101: Receive instruction information sent by a network device.

Optionally, indication information sent by the receiving network device in a preset manner.

Optionally, the preset method may be one or more of the following methods:

Broadcasting method;

Multicast mode;

Unicast mode.

Optionally, the indication information may be one or more of the following signalings on the air interface side:

L1 signaling;

L2 signaling;

L3 signaling.

Among them, L3 signaling is Radio Resource Control (RRC) signaling.

Step 102: Based on the indication information, determine the target stage of the serving cell of the terminal device in the discontinuous transmission state, the target stage being a non-activated stage or an activated stage.

The service cell is a cell covered by the network device, which enables the terminal device to communicate with the network device.

Optionally, the number of service cells of the terminal device can be 1 or more.

Optionally, discontinuous transmission includes discontinuous sending and/or discontinuous receiving.

In some embodiments, the non-active period includes a Cell DRX non-active period and/or a Cell DTX non-active period.

The active period includes the Cell DRX activation period and/or the Cell DTX activation period.

In the communication method provided in the embodiment of the present disclosure, based on the indication information sent by the network device, the target stage of the service cell of the terminal device in the discontinuous transmission state is determined, so that the target stage of the service cell in the discontinuous transmission state can be accurately determined (that is, the service cell is accurately determined to enter the activation stage or the inactivation stage).

In some embodiments, determining, based on the indication information, a target phase in which a serving cell of the terminal device is in a discontinuous transmission state includes:

In case that the indication information is non-activation phase indication information, it is determined that the target phase of the service cell of the terminal device in the discontinuous transmission state is the non-activation phase.

The interaction process between the terminal device and the network device is described below with reference to FIG. 2 .

FIG2 is one of the interactive flow diagrams of the communication method provided in the embodiment of the present disclosure. As shown in FIG2 , the method includes:

Step 201: The network device sends inactive phase indication information to the terminal device.

Optionally, when the serving cell of the terminal device is in the Cell DTX activation phase, if the network device determines to shut down the transmitter corresponding to the serving cell based on the network side policy, or partially shut down the transmitter corresponding to the serving cell, the serving cell can only send part of the specific information, thereby reducing the energy consumption caused by the sending of the serving cell, and then sends the non-activation phase indication information to the terminal device. Optionally, the network side policy can be to reduce the network load, for example, there is no DL data to be transmitted.

Optionally, the network device sends a signal to the terminal device via broadcast, multicast or unicast. Send inactive phase indication information.

Optionally, the inactive phase indication information may be L1 signaling, L2 signaling or L3 signaling on the air interface side.

In some embodiments, the inactive phase indication information includes one or more of the following:

The identification of the serving cell;

a first preset quantity;

The first specified duration of time that the serving cell is in the inactive phase;

Discontinuous transmission type.

Optionally, the identifier of the service cell may be the ID of the service cell, or an index number, or a first preset value. The first preset value is a value on a first preset bit position, and the first preset bit position is a bit position corresponding to the service cell in the non-activation phase indication information. Optionally, the first preset value may be 0 or 1, etc. For example, 3 service cells are preset, and 3 bits are used to represent each service cell. Service cell 1 corresponds to the first bit, service cell 2 corresponds to the second bit, and service cell 3 corresponds to the third bit. If the first preset value on the first bit position is 1, it means that the non-activation phase indication information is applied to service cell 1.

Optionally, a first preset number (for example, N, where N is an integer greater than or equal to 1) included in the inactive phase indication information can be used to indicate that the target phase of the serving cell within N consecutive Cell DTX cycles is the Cell DTX inactive phase.

Step 202: Based on the inactive phase indication information, determine that the target phase of the serving cell of the terminal device in the discontinuous transmission state is the inactive phase.

Furthermore, based on the content included in the inactive phase indication information, a target serving cell whose target phase is the inactive phase is determined.

For example, in the case where the discontinuous transmission type is Cell DTX, if the network device is configured with Cell DTX for multiple service cells, the identifier of the service cell included in the non-activation phase indication information determines that the target service cell is the service cell corresponding to the identifier (there can also be multiple target service cells here).

Further, when the non-activated phase indication information includes the discontinuous transmission type, the target phase is determined to be the Cell DRX non-activated phase and/or the Cell DTX non-activated phase.

Furthermore, after receiving the inactive phase indication information, it is also possible to determine, based on a default method, a target serving cell whose target phase is the inactive phase.

For example, when there are multiple service cells, the default method may be that if the non-activation phase indication information is received from the target service cell (any one of the multiple service cells), it is considered applicable to the target service cell; or, it is applicable by default to all multiple service cells configured with Cell DTX.

Step 203: Determine a first duration of time during which the serving cell is in an inactive phase.

In some embodiments, the first duration is one or more of the following:

The discontinuous transmission period of the current cell in the inactive phase;

The product of the cell discontinuous transmission period and a first preset number;

First specified duration.

Optionally, the first duration can be determined as the discontinuous transmission period of the current cell in the inactive phase based on a protocol predefined method, that is, the service cell enters the Cell DTX inactive phase until the next Cell DTX period.

Optionally, the first duration may be determined as the product of the cell discontinuous transmission period and the first preset number based on at least one of the following methods 11, 12 and 13.

Mode 11, based on the first preset number included in the inactive phase indication information, the first duration is determined to be the product of the cell discontinuous transmission period and the first preset number.

Method 12, based on a protocol predefined method, determines that the first duration is the product of the cell discontinuous transmission period and a first preset number, wherein the first preset number is a number agreed upon in the protocol.

Method 13, based on a first preset number indicated by the network device through other signaling, determines that the first duration is the product of the cell discontinuous transmission period and the first preset number.

Optionally, the first duration may be determined to be the first specified duration based on at least one of the following methods 21, 22, and 23.

Mode 21: Based on the first designated duration included in the inactive phase indication information, the first duration is determined to be the first designated duration.

Mode 22, based on a protocol predefined mode (a first specified duration agreed upon in the protocol), determining the first duration as the first specified duration, wherein the first specified duration is the specified duration agreed upon in the protocol;

Mode 23, determining a first holding time based on a first preset number indicated by the network device through other signaling The continuation duration is the first specified duration.

Furthermore, in the embodiment of the present disclosure, after the first duration ends, the periodic Cell DTX is restored.

It should be noted that some of the explanations in the embodiment of FIG. 2 are explained by taking the case where the discontinuous transmission type is Cell DTX as an example. In the case where the discontinuous transmission type is Cell DRX, if the network device finds that the terminal device no longer needs to monitor UL data in the serving cell, or only needs to monitor part of the UL data and/or part of the UL signaling, the preset manner in which the network device sends the non-activation phase indication information to the terminal device, the content included in the non-activation phase indication information, and the behavior of the terminal device receiving the non-activation phase indication information are the same as those in the case where the discontinuous transmission type is Cell DTX, and are not described in detail here.

In the embodiment of Figure 2, the network device sends non-activation phase indication information to the terminal device. Based on the non-activation phase indication information, the terminal device determines that the target phase of the service cell of the terminal device in the discontinuous transmission state is the non-activation phase. This allows the network device and the terminal device to adjust the target phase of the service cell to the non-activation phase in a timely manner, thereby reducing power consumption of the network device and the terminal device.

In some embodiments, determining, based on the indication information, a target phase in which a serving cell of the terminal device is in a discontinuous transmission state includes:

In case that the indication information is activation phase indication information, it is determined that the target phase of the serving cell of the terminal device in the discontinuous transmission state is the activation phase.

In the disclosed embodiment, the network device may also decide to extend the duration that the service cell is in the activation phase, and notify the terminal device to extend the duration that the service cell is in the activation phase.

Optionally, the network device extends the duration of the serving cell being in the activation phase to a fixed duration.

FIG3 is a second interactive flow diagram of a communication method provided in an embodiment of the present disclosure. As shown in FIG3 , the method includes:

Step 301: The network device sends activation phase indication information to the terminal device.

Optionally, in the case where the serving cell periodically enters the Cell DTX inactive phase, if the network device determines based on the network side policy that the serving cell is in the Cell DTX inactive phase and there is still DL data to be transmitted, then the activation phase indication information is sent to the terminal device. Optionally, the network side policy may be that the amount of DL data to be transmitted is greater than a preset threshold or the DL data has a high latency requirement and cannot wait until the next Cell DTX active phase of the serving cell to be transmitted. Specifically, the network side policy is not specifically limited here.

Optionally, the network device sends activation phase indication information to the terminal device via broadcast, multicast or unicast.

Optionally, the activation phase indication information may be L1 signaling, L2 signaling or L3 signaling on the air interface side.

Optionally, the activation phase indication information and the inactivation phase indication information may be the same signaling or different signaling.

For example, when the activation phase indication information and the inactivation phase indication information are different signalings, the activation phase indication information may be L1 signaling, and the inactivation phase indication information may be L2 signaling; or Alternatively, the activation phase indication information may be L2 signaling, and the inactivation phase indication information may be L1 signaling.

Optionally, the activation phase indication information includes one or more of the following:

The identification of the serving cell;

A second preset quantity;

A second specified time duration during which the serving cell is in the activation phase;

Discontinuous transmission type, discontinuous transmission type includes Cell DRX and/or Cell DTX.

Optionally, the identifier of the serving cell may be an ID of the serving cell, or an index number, or a second preset value. The second preset value is a value on a second preset bit position, and the second preset bit position is a bit position corresponding to the serving cell in the inactive phase indication information. Optionally, the second preset value may be 0 or 1, etc. The first preset value and the second preset value may be the same or different. For example, when the first preset value is 0, the second preset value is 1.

Optionally, the activation phase indication information includes a second preset number (an integer greater than or equal to 1), which is used to indicate that the serving cell will be in the Cell DTX activation phase for n consecutive Cell DTX cycles.

Optionally, when the network device is configured with multiple second specified durations for the Cell DTX activation phase, at least one bit may be used in the activation phase indication information to indicate the second specified duration corresponding to the serving cell.

Step 302: Based on the activation stage indication information, determine that the target stage of the serving cell of the terminal device in the discontinuous transmission state is the activation stage.

Furthermore, the target serving cell whose target stage is the activation stage may be determined based on the content included in the activation stage indication information.

For example, in the case where the discontinuous transmission type is Cell DTX, if the network device is configured with Cell DTX for multiple service cells, the service cell identifier included in the activation phase indication information determines that the target service cell is the service cell corresponding to the identifier (which can be multiple).

Further, when the activation phase indication information includes the discontinuous transmission type, the target phase is determined to be the Cell DRX inactive phase and\or the Cell DTX inactive phase.

Furthermore, after receiving the activation phase indication information, the target serving cell in the activation phase may be determined based on a default method.

For example, when there are multiple service cells, the default method may be that if activation phase indication information is received from a target service cell (any one of multiple service cells), it is considered applicable to the target service cell; or, it is applicable by default to all multiple service cells configured with Cell DTX.

Step 303: determine a second duration of the serving cell being in the activation phase.

Optionally, the second duration can be determined based on a protocol predefined method as the discontinuous transmission period of the current cell in the activation phase, that is, the serving cell enters the Cell DTX activation phase until the next Cell DTX period.

Optionally, the second duration may be determined based on at least one of the following methods 31, 32 and 33 as the product of the cell discontinuous transmission cycle and the second preset number.

Mode 31: Based on the second preset number included in the activation phase indication information, determine the second duration as the product of the cell discontinuous transmission period and the second preset number.

Method 32, based on a protocol predefined method (a second preset number agreed upon in the protocol), determines that the second duration is the product of the cell discontinuous transmission period and the second preset number.

Method 33, based on a second preset number indicated by the network device through other signaling, determines that the second duration is the product of the cell discontinuous transmission period and the second preset number.

Optionally, the second duration may be determined as the second specified duration based on at least one of the following methods 41 , 42 and 43 .

Mode 41: Based on the second designated duration included in the activation phase indication information, the second duration is determined to be the second designated duration.

Mode 42, based on the protocol predefined mode (the protocol stipulates the second specified time length), determining the second duration as the second specified time length;

Method 43, based on a second preset number indicated by the network device through other signaling, determining the second duration as a second specified duration.

Optionally, after the second duration expires, periodic Cell DTX may be resumed.

Furthermore, after the network device determines that the service cell enters the Cell DTX activation phase, if the data to be sent (such as DL data to be transmitted) or the data to be received is processed in advance, the network device can send a non-activation phase indication information to the terminal device to notify the terminal device that the target phase of its service cell is the Cell DTX non-activation phase.

It should be noted that some of the explanations in the embodiment of FIG3 are explained by taking the case where the discontinuous transmission type is Cell DTX as an example. In the case where the discontinuous transmission type is Cell DRX, the preset manner in which the network device sends the activation phase indication information to the terminal device, the content included in the activation phase indication information, and the behavior of the terminal device receiving the activation phase indication information are the same as those in the case where the discontinuous transmission type is Cell DTX, and are not described in detail here.

In the embodiment of Figure 3, the network device sends activation stage indication information to the terminal device, and based on the activation stage indication information, determines that the target stage of the service cell of the terminal device in the discontinuous transmission state is the activation stage, so that the activation stage can be extended in time to ensure good service quality while saving energy.

Optionally, the time period during which the network device extends the serving cell in the activation phase is a variable time period. This will be described below in conjunction with FIG.

FIG4 is a third interactive flow diagram of the communication method provided in the embodiment of the present disclosure. As shown in FIG4 , the method includes:

Step 401: The network device sends activation phase indication information to the terminal device.

In some embodiments, the target PDCCH is one or more of the following:

PDCCH for serving cell scheduling data;

The serving cell schedules the PDCCH for new transmission data.

Step 403, after receiving the activation phase indication information sent by the network device, the terminal device starts or restarts the timer with a timing duration of the second duration each time it receives the target PDCCH, and determines that the target phase of the serving cell within the second duration is the activation phase.

Optionally, step 403 may also include: the terminal device determines a second duration during which the serving cell is in the activation phase.

Optionally, when the activation phase indication information includes a second preset number, the product of the second preset number and the cell discontinuous transmission period is determined as the second duration.

Optionally, when the activation phase indication information includes a second specified duration, the second specified duration is determined as the second continuous duration.

Optionally, the second duration may also be configured by the network device through other signaling or agreed upon by a protocol.

Further, in the case where the target stage is the activation stage, if the terminal device receives the non-activation stage indication information sent by the network device, it is determined that the target stage of the service cell in the discontinuous transmission state is the non-activation stage.

In the method provided in the embodiment of Figure 4, after the network device sends the activation phase indication information to the terminal device, in combination with the target PDCCH received each time, based on the activation phase indication information, it starts or restarts the timer with a timing duration of the second duration, and determines that the target phase of the service cell within the second duration is the activation phase. The activation phase can be extended in a timely and dynamic manner, ensuring the service quality while ensuring energy saving of the network device and the terminal device.
