Description

Transmission method, device, terminal and network equipment for channel occupation time

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method, an apparatus, a terminal, and a network device for transmitting channel occupation time.

Background

In order to more flexibly utilize frequency resources in a New air interface (NR) of 3GPP, a direct communication interface Unlicensed spectrum (SL-U) is introduced for a direct communication interface.

For SL-U, after introducing the LBT (Listen Before Talk listen before talk) mechanism, the terminal will continue to occupy the channel once it competes to resources through the LBT procedure. If the network side device (such as the base station) cannot know the channel occupation time (Channel Occupy Time, COT) of the terminal, only blind scheduling can be performed, which may cause direct communication interface resources allocated by the network device to the terminal to be out of the COT, resulting in direct communication interface resource waste. If the direct communication peer of the terminal cannot learn the COT, the direct communication peer of the terminal may not select a suitable LBT type. However, how to allow the direct communication counterpart or the network side device of the terminal to acquire the COT information is not defined at present.

The embodiment of the application provides a transmission method, a transmission device, a terminal and network equipment for channel occupation time, which are used for solving the problem that how to enable a communication opposite terminal or network side equipment of the terminal to acquire COT information of the terminal is unclear in the prior art.

Referring to fig. 1, an embodiment of the present application provides a method for transmitting channel occupation time, which is applied to a first terminal, and specifically includes the following steps:

Step 101, triggering target information when a first condition is met, wherein the target information is used for indicating channel occupation time COT information of a first terminal to target equipment; the target device comprises network equipment and/or a second terminal, and the second terminal is a target communication opposite terminal of the first terminal through direct communication interface communication.

Alternatively, when the first condition is satisfied, the trigger target information may be understood as: when the first condition is satisfied, the target information needs to be transmitted to the target device. As to whether the first terminal can send the target information to the target device or not, it is further determined based on whether there are available resources, for example, after the target information is indicated to the network device is triggered, if the network device allocates uplink resources to the first terminal and the uplink resources can carry the target information, the first terminal may send the target information on the uplink resources allocated to the first terminal by the network device; for example, after the target information is indicated to the network device by triggering, starting a timer, and if the network device does not allocate uplink resources for the first terminal before the timer is overtime, the terminal device does not send the target information to the network device; for example, after triggering to indicate the target information to the second terminal, if the network device allocates a direct communication interface resource for the first terminal and the direct communication interface resource can carry the target information, the first terminal may send the target information on the direct communication interface resource allocated for the first terminal by the network device; for example, after the target information is indicated to the second terminal by triggering, a timer is started, and if the network device does not allocate the direct communication interface resource for the first terminal until the timer is overtime, the terminal device does not send the target information to the target communication opposite terminal of the direct communication interface.

In the above embodiment, in the case that the direct communication interface supports SL-U, a scheme that the first terminal triggers to indicate the COT information to the network device and/or the target communication peer (second terminal) of the direct communication interface communication can be implemented. Thus, for the first terminal using Mode 1, if the network device (such as the base station) can acquire the COT time, the network device can schedule the first terminal as much as possible in the COT time, thereby improving the reliability of successful transmission and improving the resource utilization rate. In addition, if the target communication peer is able to acquire the COT of the first terminal, the target communication peer may also be assisted in better determining the listen before talk type (LBT type) to be used.

In an alternative embodiment, in the case that the target device comprises the network device, the first condition comprises any one of:

The first terminal determines CAPC values by itself;

The first terminal determines COT information;

In an alternative embodiment, in case the target device comprises the second terminal, the first condition comprises at least one of:

the network equipment configures the first terminal to start COT sharing;

The first terminal determines CAPC values by itself;

For example, in the case where the target device includes the second terminal, the first condition may include any one of:

The DCI sent by the network equipment does not carry CAPC indication information;

The network equipment configures the first terminal to start COT sharing, and the DCI sent by the network equipment does not carry CAPC indication information;

The second terminal indicates to the first terminal that the second terminal supports or has started COT sharing, and the DCI sent by the network device does not carry CAPC indication information;

The network equipment configures the first terminal to start COT sharing, the second terminal indicates to the first terminal that the second terminal supports or has started COT sharing, and the DCI sent by the network equipment does not carry CAPC indication information;

The first terminal determines CAPC values by itself;

the network equipment configures the first terminal to start COT sharing, and the first terminal determines CAPC values by itself;

The second terminal indicates to the first terminal that the second terminal supports or has started COT sharing, and the first terminal determines CAPC values by itself;

the first terminal determines a COT;

The network equipment configures the first terminal to start COT sharing, and the first terminal determines COT;

the second terminal indicates to the first terminal that the second terminal supports or has started COT sharing, and the first terminal determines COT;

The network device configures the first terminal to start COT sharing and the second terminal indicates to the first terminal that the second terminal supports or has started COT sharing, and the first terminal determines COT.

Further, in an embodiment of the present application, in step 101, after triggering the target information when the first condition is met, the method further includes:

And sending the target information to the target equipment.

When the sending condition is met, the first terminal can send the target information to the target equipment through target signaling; the target signaling includes one of: radio resource Control, RRC, signaling, medium access Control (MEDIA ACCESS) security, control Element (CE), and physical layer signaling; the physical layer signaling includes: first stage SCI (stage 1 SCI) and second stage SCI (stage 2 SCI).

In an alternative embodiment, the target information includes any one of the following:

COT information;

CAPC values;

priority indication information in SCI.

In this embodiment, when the target information includes the COT information, the first terminal indicates the COT information to the target device by displaying an indication; in case that the target information includes CAPC values or priority indication information in SCI, the first terminal indicates COT information to the target device by means of a implicit indication.

It should be noted that, in the case that the target information includes CAPC values, the terminal may determine the corresponding COT according to CAPC values; in the case that the target information includes priority indication information in the SCI, the terminal may determine CAPC values (e.g., further quantize the priority in the SCI, e.g., if the priority in the SCI is 0/1, then the corresponding CAPC value is 1, and so on) according to the priority indication information in the SCI, and further determine the corresponding COT according to the CAPC value. Specifically, the COT information may be determined according to CAPC values and Table 1 below. Wherein, table 1 below shows:

TABLE 1

In table 1, CWp denotes a contention window range (contention window for a given priority class) corresponding to each priority class (priority class); CWmin, p denotes the contention window minimum value (Maximum contention window for a given priority class) corresponding to each priority level; CWmax, p denotes the contention window maximum value (Maximum contention window for a given priority class) corresponding to each priority level; tslmcot, p denotes the COT, i.e. the resource occupation time per priority class (Maximum channel occupancy time for a given priority class).

In a specific embodiment of the present application, the COT information includes any one of the following:

In a specific embodiment of the present application, in a case where the target information includes the CAPC values, the target information further includes a time domain starting point corresponding to the COT.

In this embodiment, after receiving the target information, the target device may determine the terminal channel occupation time according to the target information. For example, if the target information is CAPC, the first terminal may determine the duration of the COT according to CAPC, and then determine the specific time period corresponding to the COT according to the time domain starting point corresponding to the COT.

In an optional embodiment of the present application, in step 101, after triggering the target information when the first condition is met, the method further includes at least one of:

It should be noted that, as shown in fig. 2, two adjacent terminals may perform data transmission through a direct communication link (also referred to as Sidelink or a PC5 or a bypass) within a short range, where a wireless interface corresponding to the Sidelink link is referred to as a direct communication interface (also referred to as a Sidelink interface or a PC5 interface or a bypass interface); and the terminal and the network side equipment transmit uplink and downlink data/control information through a Uu interface.

In this embodiment, after the target information is indicated to the network device by triggering, if the uplink UL resource can carry the target information, the first terminal has sent the target information to the network device through the uplink UL resource, so that the triggered target information needs to be cancelled; after the triggering indicates the target information to the network equipment, if the first timer is overtime, the fact that the sending resource is not allocated in the timing duration of the first timer is indicated, so that the triggered target information needs to be canceled. Similarly, after the target information is indicated to the second terminal by triggering, if the through link SL resource can bear the target information, the first terminal sends the target information to the second terminal through the through link SL resource, so that the triggered target information needs to be cancelled; after the target information is indicated to the second terminal by triggering, if the second timer is overtime, the fact that the sending resource is not allocated in the timing duration of the second timer is indicated, so that the triggered target information needs to be canceled.

In an alternative embodiment of the present application, the method further comprises at least one of:

In this embodiment, through the timer mechanism, it is possible to avoid waiting all the time when the terminal cannot obtain UL resources and/or SL resources, and also to ensure timeliness of target information transmission, and cancel triggered target information in time after timeout.

In this embodiment, after the first terminal triggers the scheduling request SR, the network device allocates uplink UL resources and/or through link SL resources for the first terminal according to the scheduling request SR; further, the first terminal sends target information to the network device according to the allocated uplink UL resource, and the first terminal sends target information to the second terminal according to the allocated through link SL resource.

In an optional embodiment of the present application, the method further includes:

Illustratively, in step 101, before the target information is triggered when the first condition is met, configuration information sent by the network device is received.

In this embodiment, it is possible to realize an independent configuration of the on or off of the function of triggering the transmission of the target information to the second terminal and the on or off of the function of triggering the transmission of the target information to the second terminal.

Illustratively, in the step 101, before the target information is triggered when the first condition is met, terminal capability indication information is sent to the network device.

Note that, in the COT sharing mechanism, if the transmitting terminal (the first terminal in the present application) and the receiving terminal (the second terminal in the present application) support COT sharing, the transmitting terminal may share the COT acquired by the transmitting terminal with the desired receiving terminal. The receiving terminal may decide an LBT type (type) based on the COTs of the transmitting terminal. If the desired reception terminal is to transmit a time outside the COTs of the transmission terminals, it is necessary to acquire the COTs used by the reception terminals using LBT type 1.

The transmission method of the channel occupation time of the present application will be described with reference to specific examples.

Example one: the first terminal sends target information for indicating COT to the service base station

As shown in fig. 3, the transmission method of the channel occupation time may include the steps of:

Step 1, the first terminal (UE 1) performs LBT.

If the first terminal supports SL-U, if the first terminal has a Transport Block (TB) to send on the SL-U spectrum, the first terminal needs to use an LBT (Listen Before Talk listen before talk) mechanism for data transmission. When the first terminal competes to the resource through the LBT procedure, the resource may be continuously occupied for a certain time (i.e., COT).

Specifically, the first terminal may determine the duration of the channel occupation time COT according to the CAPC value. The method for determining CAPC by the first terminal includes:

mode 1: if the DCI includes CAPC indication, the first terminal determines a corresponding COT according to the CAPC value indicated in the DCI.

Mode 2: if the DCI does not include CAPC, the first terminal determines CAPC according to the content included in the TB, specifically in the following manner:

Mode 2-1: if only MAC CEs are included in the SL TB, then SL CAPC of the highest priority is used (i.e., SL CAPC takes the lowest value of 1);

Mode 2-2: if the TB contains a cut-through link control channel (Sidelink Control Channel, SCCH) service data Unit (SERVICE DATA Unit, SDU), then the highest priority SL CAPC is used (i.e., SL CAPC takes the lowest value of 1);

Mode 2-3: if the TB contains both MAC CE and logical channel data, one possible way is to use SL CAPC of the highest priority;

mode 2-3: if only data for a logical channel is contained in the TB, one possible way is to determine by SL CAPC the highest priority of the logical channel configuration.

Wherein, after the first terminal determines CAPC values, the COT information may be determined according to CAPC and table 1 above.

Step 2: and triggering target information, wherein the target information is used for indicating COT of the indication first terminal to the network equipment.

Specifically, when the first condition is met, triggering to indicate target information to the network equipment; wherein the first condition comprises any one of:

The first terminal determines CAPC values by itself;

The first terminal determines COT information;

Step 3: triggering SR

It should be noted that this step 3 is an optional step. When the target information is indicated to the network device by triggering, if the first terminal has UL resources on the Uu interface and the UL resources can carry the target information, the step 3 may be omitted.

In the step, when the first terminal triggers to indicate target information to the network equipment, if the first terminal has no resource available on the Uu interface or the Uu interface can not bear the target information although having the resource, the SR is triggered. Here, the triggered SR may use dedicated SR resources corresponding to the COT or carry specific indication information in the buffer status report (bufferstatusreport, BSR) to indicate that there is COT data to be transmitted.

Step 4: the network device allocates an uplink scheduling grant (UL grant) for the first terminal

In this step, the network device allocates an UL grant to the first terminal, where the UL grant is used to determine an uplink transmission signal format of the first terminal, and includes: resource allocation information and transport format.

It should be noted that this step 4 is not necessarily associated with the above steps 1 to 3, and only the terminal needs to be able to acquire the UL grant before step 5.

Step 5: and the terminal sends the target information to the network equipment.

In this step, the signaling manner used for the transmission of the target information may be one of the following: RRC signaling, MAC CE, and physical layer signaling.

The specific embodiment form of the target information may be one of the following:

the explicit mode is as follows: namely, the target information comprises COT information;

implicit mode: i.e. the destination information contains CAPC values or priority indication information in SCI.

The COT information comprises a time domain starting point corresponding to COT and the length of the COT; or a time domain starting point corresponding to COT and a time domain terminal corresponding to COT.

Optionally, if the target information includes CAPC values, the target information may further include at least a time domain starting point corresponding to the COT.

In addition, after the target information is indicated to the network equipment by triggering, if uplink UL resources can bear the target information or a first timer is overtime, the triggered target information is canceled;

Triggering the function to indicate to the network device whether the target information is in an on (enabled) state or an off (disabled) state may be based on a network configuration or a pre-configuration.

Example two: the first terminal sends target information for indicating COT to the second terminal

As shown in fig. 4, the transmission method of the channel occupation time may include the steps of:

step 1, the first terminal (UE 1) performs LBT

In the case that the first terminal supports SL-U, if the first terminal has a Transport Block (TB) to transmit on the SL-U spectrum, the terminal needs to use an LBT (Listen Before Talk listen before talk) mechanism for data transmission. Once a terminal competes for a resource through the LBT procedure, the resource may be continuously occupied for a certain time.

Specifically, the first terminal may determine the duration of the channel occupation time COT according to the CAPC value. The detailed description of the embodiment is given in the above example one, and for avoiding repetition, a detailed description is omitted here.

Step 2: and triggering target information, wherein the target information is used for indicating COT of the first terminal to the second terminal.

Specifically, when the first condition is satisfied, triggering target information; wherein the first condition comprises any one of:

The first terminal determines CAPC values by itself;

Step 3: triggering the SR.

It should be noted that this step 3 is an optional step. When the trigger indicates the target information to the second terminal, if the first terminal has a SL grant on the direct communication interface and the SL grant is capable of carrying the target information, this step 3 may be omitted.

In the step, after the target information is indicated to the second terminal by triggering, if the first terminal uses a resource allocation mode of network scheduling at a direct communication interface and the first terminal has no available resource at the direct communication interface, an SR is triggered; or after the target information is indicated to the second terminal by triggering, if the first terminal uses a resource allocation mode of network scheduling at a direct communication interface and the first terminal cannot bear the target information at the resources of the direct communication interface, triggering an SR.

Here, the triggered SR may use a dedicated SR resource corresponding to the COT, an SR resource multiplexing existing SL Channel State Information (CSI), or carry specific indication information in a buffer status report (bufferstatusreport, BSR) to indicate that there is COT data to be transmitted.

Step 4: the network device allocates a SL grant for the first terminal.

It should be noted that step 4 and steps 1 to 3 are not necessarily associated, and only the first terminal needs to be able to acquire the SL grant before step 5.

Step 5: the first terminal transmits the target information to its direct communication interface communication counterpart (second terminal UE 2).

In addition, after the target information is indicated to the second terminal by triggering, if the through link SL resource can bear the target information or the second timer is overtime, the triggered target information is canceled; when the target information is triggered to be indicated to the second terminal, starting the second timer; stopping the second timer when the SL resource is determined to be capable of bearing the target information; the length of the timing of the second timer is equal to the length of the COT.

Triggering the function to indicate to the second terminal whether the target information is in an on (enabled) state or an off (disabled) state may be based on a network configuration or a pre-configuration.

Example three: the first terminal sends target information for indicating COT to the second terminal and the target device

As shown in fig. 5, the transmission method of the channel occupation time may include the steps of:

step 1, the first terminal (UE 1) performs LBT

If the terminal supports SL-U, if the terminal has a Transport Block (TB) to transmit on the SL-U spectrum, the terminal needs to use LBT (Listen Before Talk listen before talk) mechanism for data transmission. Once a terminal competes for a resource through the LBT procedure, the resource may be continuously occupied for a certain time.

Specifically, the terminal may determine the duration of the channel occupation, COT, according to the CAPC values. The detailed description of the embodiment is given in the above example one, and for avoiding repetition, a detailed description is omitted here.

Step 2: and triggering target information, wherein the target information is used for indicating COT of the first terminal to the second terminal and the target equipment.

Specifically, the indication of the target information to the network device is triggered when one of the following conditions is met:

The first terminal determines CAPC values by itself;

The first terminal determines COT information;

Specifically, the indication of the target information to the second terminal is triggered when one of the following conditions is satisfied:

The first terminal determines CAPC values by itself;

the first terminal determines a COT;

Step 3a: triggering SR

It should be noted that this step 3a is an optional step. When the trigger indicates the target information to the second terminal, this step 3a may be omitted if the first terminal has a SL grant on the direct communication interface and the SL grant is able to carry the target information.

Step 3b: network equipment distributes SL grant for first terminal

The network device allocates a SL grant for the terminal. The step and the step 1/2/3a are not necessarily related, and the terminal can acquire the SL grant before the step 5.

It should be noted that, the above steps 3a/3b and the following steps 4a/4b have no sequence requirement, so long as the base station is guaranteed to be able to allocate a SL grant for the first terminal.

Step 4a: triggering SR

It should be noted that this step 4a is an optional step. When the target information is indicated to the network device by triggering, if the first terminal has UL resources on the Uu interface and the UL resources can carry the target information, the step 3 may be omitted.

In the step, when the first terminal triggers to indicate target information to the network equipment, if the first terminal has no resource available on the Uu interface or the Uu interface can not bear the target information although having the resource, the SR is triggered.

Here, the triggered SR may use dedicated SR resources corresponding to the COT or carry specific indication information in the buffer status report (bufferstatusreport, BSR) to indicate that there is COT data to be transmitted.

Step 4b: network equipment allocates UL grant for first terminal

It should be noted that, the steps 3a/3b and 4a/4b have no sequence requirement, so long as the network device is guaranteed to be able to allocate UL grant for the first terminal.

Step 5a: the first terminal transmits target information to its direct communication interface communication counterpart (UE 2), respectively.

Step 5b: the first terminal sends target information to the network device.

In the above step 5a/5b, the signaling manner used for the transmission of the target information may be one of the following: RRC signaling, MAC CE, and physical layer signaling.

In addition, in the step 5b, after the target information is indicated to the network device by triggering, if the uplink UL resource can carry the target information or the first timer times out, the triggered target information is cancelled; starting the first timer when triggering to indicate the target information to the network equipment; stopping the first timer when the UL resource is determined to be capable of bearing the target information; wherein the length of the timing of the first timer is equal to the length of the COT.

In the step 5a, after the target information is indicated to the second terminal by triggering, if the through link SL resource can bear the target information or the second timer is overtime, the triggered target information is cancelled; when the target information is triggered to be indicated to the second terminal, starting the second timer; stopping the second timer when the SL resource is determined to be capable of bearing the target information; the length of the timing of the second timer is equal to the length of the COT.

Here, the on or off of the function of triggering the transmission of the target information to the second terminal and the on or off of the function of triggering the transmission of the target information to the second terminal may be configured independently.
