Description

Method and equipment for resource allocation and data transmission

The present invention claims priority from chinese patent office, application number 201910023977.8, application name "a method and apparatus for resource allocation and data transfer" filed on 1 month 10 2019, the entire contents of which are incorporated herein by reference.

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and apparatus for resource allocation and data transmission.

Background

The existing LTE (Long Term Evolution ) provides a mechanism for an uplink scheduling request (Scheduling Request, SR) that if a UE has no uplink data to transmit, an eNodeB (Evolved Node B) does not need to allocate uplink resources for the UE, otherwise it may cause resource waste. Therefore, the UE (User Equipment) needs to tell the eNodeB itself whether there is uplink data to be transmitted or not, so that the eNodeB decides whether to allocate uplink resources to the UE or not. For this reason, the eNodeB may allocate a dedicated SR resource to each UE for transmitting the SR, and when the UE has uplink data to transmit but does not have an uplink resource, the UE transmits the SR on the SR resource, and requests the eNodeB to allocate the uplink resource, which clearly increases the system delay.

Therefore, 3GPP (Third Generation Partnership Project ) protocol proposes a concept of pre-configured resources, where network side devices can pre-configure resources for a terminal, where types of pre-configured resources include pre-configured resource type 1 and pre-configured resource type 2, and when the terminal has a service transmission requirement, the pre-configured resources can be used for transmission, so as to reduce transmission delay, save a delay of sending a scheduling request by the terminal, obtain uplink resources for buffer reporting, and retransmit data.

When the pre-configured resource is configured for the terminal, the network side device and the terminal can negotiate the data starting point about to arrive by the terminal, but in practice, the starting point of the pre-configured resource configured by the network side device is difficult to be completely matched with the data starting point about to arrive by the terminal, so that the terminal may need to wait for the next pre-configured resource period to send data, and therefore, although the pre-configured resource relieves the problem of transmission delay, the delay requirement of the scene with high delay requirement cannot be met, for example, an important scene proposed in the current 5G system, namely a URLLC (Ultra Reliable Low Latency Communications, ultra high reliability low delay) scene, and the scene requires the end-to-end delay to reach 0.5ms.

In summary, the transmission delay of the current resource pre-configuration method is larger, and the low-delay service requirement of the 5G system cannot be met.

Disclosure of Invention

And after receiving the configuration command sent by the network side, the terminal immediately uses the periodic resource to carry out data transmission. Fig. 1 is a schematic diagram of a scenario in which a network side device configures a preconfigured resource type1 for a terminal.

configured grant Type2 is a period in which the network side allocates periodic resources to the terminal using RRC signaling and a CS-RNTI for scheduling the periodic resources. When the network side decides to allocate the actual resource, a PDCCH order is sent to indicate the starting point of the periodic resource and specific transmission resources (time-frequency resources, etc.), transmission formats (MCS, etc.). The terminal does not have available resources when receiving the RRC signaling of the pre-configured resources, and the pre-configured resources are actually allocated after receiving the activation command of the PDCCH. Fig. 2 is a schematic diagram of a scenario in which a network side device configures a preconfigured resource type2 for a terminal.

When the network side equipment allocates the pre-configured resources for the terminal, the network side equipment can estimate the starting point of the resources and is approximately aligned with the business of the terminal, or the world where the estimated data of the terminal arrives can report the business model, and the network side equipment and the terminal negotiate the starting point position of the pre-configured resources allocated to the terminal. When the data of the terminal arrives, the terminal can use the pre-configured resource to report the data. But the start point of the pre-configured resource is difficult to match with the data that the terminal arrives at, so the terminal may need to wait for the next pre-configured resource period to send the data, referring to the scenario shown in fig. 3.

The transmission delay caused by the method has no influence on a general scene with low delay requirement, but for a scene with strict delay requirement, such as a significant test scene-URLLC scene proposed in 5G technology, the URLLC scene is suitable for industrial application and control, traffic safety and control, remote manufacturing, remote training and remote surgery, the scene requires that the end-to-end delay can reach 0.5ms (millisecond), and the transmission delay caused by the fact that the existing preconfigured resources are difficult to match with the data reached by a terminal can cause that the scene can not meet the requirement of the delay.

Therefore, the embodiment of the invention provides a method and a device for resource allocation and data transmission, wherein network side equipment pre-allocates pre-allocated resources for a terminal, wherein a set of pre-allocated resources have a plurality of continuous resource allocation in a pre-allocated resource period, and even if the starting point of the pre-allocated resources is not matched with the starting point of data to be arrived by the terminal, the terminal can select the closest resource in a plurality of connected resources for data transmission. Embodiments of the invention are described in further detail below with reference to the drawings.

As shown in fig. 4, an embodiment of the present invention provides a system for resource allocation and data transmission, where the system includes: network-side device 10 and terminal 20.

A network side device 10 for determining a plurality of consecutive resources within a period of one preconfigured resource among a set of preconfigured resources configured to the terminal; the terminal is preconfigured with a determined plurality of consecutive resources.

A terminal 20, configured to determine a plurality of continuous resources preconfigured by the network side device; and carrying out data transmission through the preconfigured plurality of continuous resources.

By the method, the network side equipment configures the pre-configured resources for the terminal in advance, wherein a set of pre-configured resources have a plurality of continuous resource allocation in one pre-configured resource period. When the terminal has data to arrive, one of a plurality of continuous pre-allocation resources is selected for data transmission, and even if the starting point of the pre-allocation resource is not matched with the starting point of the data to be arrived by the terminal, the terminal can select the closest resource to carry out data transmission in a plurality of continuous resources, so that the transmission delay is reduced.

The configuration procedure for the preconfigured resource type 1 and preconfigured resource type 2 is described below:

1. the network side equipment configures the pre-configuration resource process:

1. procedure for configuring preconfigured resource type 1: the network side equipment configures pre-configured resources for the terminal according to auxiliary information such as service arrival period, service data estimated arrival time, estimated data packet size, deviation of service data estimated arrival time and the like reported by the terminal, and determines a time starting point, a time-frequency resource position, a transmission format and the like of a first resource period of the pre-configured resources aiming at each set of pre-configured resources. Wherein, for understanding the deviation of the expected arrival time of the service data: the deviation of the expected arrival time of the service data is divided into positive and negative, and the unit of the deviation value can be a symbol, a time slot, a subframe or a millisecond. The network side equipment determines the number of a plurality of continuous resources in a pre-configured resource period according to the expected arrival time of the service data and the deviation of the expected arrival time of the service data.

For example, as shown in fig. 5, when the expected arrival time of the service data reported by the terminal is the 3 rd symbol of the subframe N and the deviation of the expected arrival time of the service data is positive 2 symbols, the network side device determines that the service data of the terminal may arrive after 2 symbols, so that the network side device determines that the number of a plurality of continuous resources in a preconfigured resource period is at least 3, specifically: starting point is 3 rd symbol of subframe N, 3 resources are allocated continuously, and assuming that service period is T subframe, 3 rd symbol of each subframe n+kt starts to pre-allocate 3 resources.

The network side equipment indicates the number of continuous resources in a pre-configured resource period through RRC signaling;

2. procedure for configuring preconfigured resource type 2: the network side equipment configures pre-configured resources for the terminal according to the service arrival period, the expected arrival time of service data, the expected data packet size, the deviation of the expected arrival time of the service data and other auxiliary information reported by the terminal, and determines the time starting point, the time-frequency resource position, the transmission format and the like of the first resource period of the pre-configured resources aiming at each set of pre-configured resources, wherein the mode for determining the number of continuous resources can be the parameter mode, and is not repeated here. The network side device indicates the number of continuous resources in a preconfigured resource period in the preconfigured resource type 2 by the following method:

Indication mode one: indication through RRC signaling;

the network side equipment can configure for the terminal through the RRC signaling and indicate the number of continuous resources in a pre-configured resource period.

Indication mode II: indicated by a PDCCH order for activating the pre-configured resources;

the network side device may indicate the number of continuous resources within one period of the pre-configured resources through a PDCCH order for activating the pre-configured resources.

In the embodiment of the present invention, whether the resource type 1 or the resource type 2 is preconfigured, in a set of preconfigured resources configured by the network side device for the terminal, one preconfigured resource period has a plurality of continuous resources, and for "a plurality of continuous" can be understood as follows:

1. continuous resources on adjacent symbols;

2. continuous resources on adjacent time slots;

3. continuous resources on adjacent subframes;

4. adjacent continuous same-direction transmission resources;

as shown in fig. 6, adjacent continuous co-directional transmission resources refer to resources that are continuously transmitted or continuously received by the same terminal, including continuous uplink resources or continuous sidelink resources.

If the adjacent continuous same-direction transmission resource is a sidelink resource, the pre-configured resource is configured by the network side equipment to the sending terminal and the receiving terminal to transmit on the sidelink interface.

2. Enabling the pre-configured resources and releasing other pre-configured resources within the same period:

the terminal receives the RRC signaling of the pre-configured resources configured by the network side equipment, and determines a plurality of continuous resources configured by the network side equipment, wherein the plurality of continuous resources in one pre-configured resource period of the pre-configured resources can be regarded as reserved for the terminal. When the terminal determines that service data arrives, one resource is selected on the preconfigured resources to report the data, after the network side equipment determines that the terminal uses the preconfigured resources to send a first data packet, the resources at the same position in each preconfigured resource period are enabled, other preconfigured resources in the same preconfigured resource period are disabled, the network side equipment releases the non-enabled resources in the preconfigured resources to the terminal, only one enabled resource exists in each preconfigured resource period, and then the terminal can transmit data on the enabled resources.

The network side equipment determines the resource position of the terminal for sending the first data packet by the following modes:

determining a first mode: determining according to the transmission power value of the terminal on the pre-configured resource;

and the network side equipment performs power detection, and determines the resource corresponding to the maximum value of the transmission power of the terminal on the plurality of pre-configured resources as the resource of the terminal for transmitting the first data packet.

And a second determination mode: determining according to the decoded data packet;

the network side equipment receives the report information of the terminal and decodes the report information, the network side equipment can determine the pre-configured resource used by the terminal for sending the first data packet according to the mode of whether the data packet is decoded or not, and if the network side equipment decodes the data packet, the resource used by the report information of the terminal at the time is determined to be the resource used by the terminal for sending the first data packet.

And determining a third mode: determining according to indication information reported by a terminal;

the terminal carries indication information in the data transmission packet, selects one resource from the preconfigured multiple continuous resources to report data, and the network side equipment takes the resource carrying the data packet containing the indication information and sent by the terminal in the preconfigured multiple continuous resources as the resource for the terminal to send the first data packet.

The indication information is carried by the MAC layer and is an MAC CE, or an MAC sub-head carrying a special indication LCID.

For the preconfigured resource type 1, a schematic diagram of a configuration and enabling scenario of the preconfigured resource type 1 is shown in fig. 7.

And for the preconfigured resource type 1, the network side equipment takes effect after configuration through RRC signaling, when the data of the terminal arrives, the terminal selects the resource closest to the arrival time on a plurality of continuous resources to send the data, the network side equipment determines that the terminal sends a first data packet on the preconfigured resource, enables the resource with the same position as the resource where the terminal sends the first data packet in each preconfigured resource period, and other preconfigured resources fail, and the network side equipment releases the resource which is not enabled in the preconfigured resources to the terminal, and then the terminal performs data transmission on the enabled resource.

For the preconfigured resource type 2, as shown in fig. 8, a scenario diagram of configuring and enabling the preconfigured resource type 2 for the terminal by the network side device is shown.

The difference between the T is that, for the preconfigured resource type 2, the network side device needs to activate the resource through the PDCCH order of activating the preconfigured resource after being configured by RRC signaling, the activated resource can be used by the terminal, when the data of the terminal arrives, the resource closest to the arrival time is selected from the activated plurality of continuous resources to send the data, after the terminal sends the resource of the first data packet, the resource at the same resource position in each preconfigured resource period is enabled, the other preconfigured resources fail, the network side device releases the resource which is not enabled in the preconfigured resources to the terminal, the terminal performs data transmission on the enabled resource, and the failed resource can be configured for other terminals to use, or can be dynamically scheduled to the terminal.

3. Process to disable pre-configured resources:

after the pre-configured resources are enabled, only one enabled pre-configured resource exists in one pre-configured resource period, the terminal transmits data on the enabled pre-configured resource, and if the disabling condition configured by the network side equipment is met, for example, the terminal does not transmit data on the enabled pre-configured resource for a long time, the enabled resource is disabled, namely, the terminal is retracted to an enabled and disabled state.

The disabling manner for preconfigured resource type 1 and preconfigured resource type 2 is described as follows:

disabling mode one: enabling the pre-configured resource by a timer or counter;

taking a timer as an example for introduction: the network side equipment sets the using time length of the disabling pre-configured resource through the timer, the terminal starts or restarts the timer when the first data packet is sent on the pre-configured resource before the pre-configured resource is activated and not enabled, and if the timer reaches the disabling time length, the terminal does not send data on the pre-configured resource enabled in the following N pre-configured resource periods, the terminal considers that the pre-configured resource is disabled, namely the terminal does not send data through the resource. Assuming N is 1, fig. 9 is a schematic diagram of a scenario in which the network side device enables the preconfigured resource type 1 through a timer. Fig. 9 distinguishes between an enabled resource and a data transmission on the enabled resource, where the enabled resource is enabled but the terminal does not transmit data on the resource, which is similar to fig. 10 and 11, and will not be described in detail.

When the timing time length of the timer reaches the use time length for disabling the pre-configured resource, the terminal judges whether to disable the pre-configured resource according to whether the terminal transmits data in 1 pre-configured resource period after the use time length is exceeded, if the terminal transmits data on the enabled resource in the subsequent 1 pre-configured resource period, the pre-configured resource is not disabled, and if the terminal does not have service data in the subsequent pre-configured resource period, i.e. the terminal does not transmit data through the pre-configured resource, the pre-configured resource is considered to be disabled, i.e. the terminal is retracted to a state with a plurality of continuous resources in one pre-configured resource period.

For another example, if N is a positive integer greater than 1, assuming that N is 2, after determining that the usage duration for disabling the pre-configuration is reached or exceeded, if the terminal does not send data through the enabled resource in the following 2 periods of pre-configuration resources, the pre-configuration resources are considered to be disabled. Fig. 10 is a schematic diagram of a scenario in which the network side device enables the preconfigured resource type 1 through a timer when N is 2. The terminal judges whether to enable the pre-configured resource according to whether the terminal transmits data in 2 pre-configured resource periods after the using time is exceeded, if the terminal transmits data on the resource enabled in the following 1 st pre-configured resource period, the terminal does not enable the pre-configured resource, and if the terminal does not have service data in the 2 (the 2 nd pre-configured resource period and the 3 rd pre-configured resource period after T1 is exceeded) pre-configured resource periods, namely, the terminal does not transmit data through the pre-configured resource any more, the pre-configured resource is disabled in the 2 nd pre-configured resource period without using the pre-configured resource to transmit data, namely, the terminal is retracted to a state with a plurality of continuous resources in one pre-configured resource period.

The network side device may also set the number of use of the pre-configured resources through a counter, where a specific implementation manner of the counter may refer to the method steps of the timer, which are not described herein.

The disabling duration or the number of the uses may be specified by a protocol, or the network device may be configured for the terminal through RRC signaling. For example, the network side device indicates the disabled use duration through RRC signaling configuring the preconfigured resource.

It should be noted that, if the timer time length reaches the use time length of the disabling pre-configured resource or the number of the data transmitted by using the pre-configured resource reaches the use number of the disabling pre-configured resource, if the terminal has a service transmission requirement, the terminal may further transmit data on the subsequent pre-configured resource until the terminal does not transmit data through the pre-configured resource any more, and then the pre-configured resource is considered to be disabled. As in the scenario shown in fig. 11.

Disabling mode two: enabling the pre-configured resource through a disabling command carried by the MAC layer;

the network side equipment receives the indication information for enabling the pre-configured resource sent by the terminal, wherein the indication information is a MAC sub-head containing LCID for indicating the pre-configured resource to be enabled, or

The network side equipment enables the pre-configured resource corresponding to the pre-configured resource number through the pre-configured resource number carried in the MAC CE.

If the LCID in the MAC sub-header indicates that the pre-configured resource is disabled, the value of the LCID in the MAC sub-header may be a specified value indicating that the pre-configured resource is disabled in the protocol, and if the LCID in the MAC sub-header sent by the terminal is the specified value of the disabled pre-configured resource, the network side device determines that the pre-configured resource configured for the terminal is disabled. The format of a specific MAC sub-PDU is a portion of fig. 11 that does not include a MAC CE.

If the indication information is a MAC CE, as shown in fig. 12, where CG (configured grant) index is a preconfigured resource number, the MAC CE may use a MAC subheader in the foregoing manner, where the MAC subheader may carry a MAC CE indicating that the corresponding MAC CE is a preconfigured resource disabling device, and disable the preconfigured resource corresponding to the preconfigured resource number according to the preconfigured resource number that is carried in the MAC CE and that the preconfigured resource disabling device is configured to enable the preconfigured resource corresponding to the preconfigured resource number. Fig. 11 is an example, and the number of bits indicating the preconfigured resource number in a specific MAC CE may be adjusted as needed.

For example, the preconfigured resource number of the preconfigured resource configured by the network side equipment for the terminal is 3, the terminal places the preconfigured resource number 3 in the MAC CE1, and enables the MAC CE of the preconfigured resource to be the MAC CE1 by carrying an indication to enable the preconfigured resource through the LCID in the MAC subheader, and then the network side equipment enables the preconfigured resource corresponding to the preconfigured resource number 3 according to the received indication information carried by the MAC CE 1. The preset resource number in the MAC CE1 corresponds to the preset resource to be disabled, and the preset resource to be disabled can also be determined by configuring the value of the preset resource number. Such as setting the CG index3 value in the MAC CE of fig. 11 to 1 (or to 0) to indicate that the preconfigured resource with preconfigured resource number 3 is disabled.

It should be noted that, for the preconfigured resource type 1, the network side device enables the preconfigured resource by:

disabling mode three: enabling the pre-configured resources through RRC signaling;

the network side equipment reconfigures the pre-configured resources with the same pre-configured resource number through the RRC signaling, and then the enabled pre-configured resources with the same pre-configured resource number are disabled.

For example, as shown in fig. 13, the network side device configures a preconfigured resource with a preconfigured resource number of 1 for the terminal, and the terminal sends data on the preconfigured resource, where one enabled resource exists in one preconfigured resource period of the preconfigured resource. When the network side equipment reconfigures the preconfigured resource with the preconfigured resource number of 1 through the RRC signaling again, the resource with the preconfigured resource number of 1 is disabled currently, and a new preconfigured resource is determined according to the RRC signaling of the reconfigurated preconfigured resource. Wherein the preconfigured resource number is for a set of preconfigured resources, and is distinguished from the resource number of the preconfigured resources hereinafter, and the resource number is for a resource in a preconfigured resource period.

It should be noted that the new preconfigured resource determined according to RRC signaling for reconfiguring the preconfigured resource may be the same as or different from the configuration of the previous preconfigured resource.

4. Releasing the enabled resources of the pre-configured resource type 2;

the first release mode is as follows: releasing the pre-configured resources by a timer or counter;

taking the counter as an example, the network side device sets the usage number of the released pre-configured resources through the counter, and when the terminal sends data through the pre-configured resources, the counter is increased by 1, and after the usage number of the released pre-configured resources is reached, the terminal does not send data on the pre-configured resources enabled in the following N pre-configured resource periods, and the terminal considers that the pre-configured resources are released. Assuming N is 1, fig. 14 is a schematic diagram of a scenario in which the network side device releases the preconfigured resource type 2 through the counter.

The duration or number of usage of the released pre-configured resources may be specified by a protocol, or configured by the network side device for the terminal through RRC signaling, or indicated by a PDCCH order for activating the pre-configured resources. For example, the network side device indicates the disabled use duration through RRC signaling configuring the preconfigured resource.

It should be noted that, if the timer time duration reaches the use duration of the released pre-configured resource or the number of the data transmitted by using the pre-configured resource reaches the use number of the released pre-configured resource, if the terminal has a service transmission requirement, the terminal may further transmit data on the subsequent pre-configured resource until the terminal does not transmit data through the pre-configured resource any more, and then the pre-configured resource is considered to be released.

And a release mode II: releasing the pre-configured resources through a release resource command carried by the MAC layer;

the network side equipment releases the pre-configured resources according to the indication information which is sent by the terminal and contains the pre-configured resources, the indication information bears the MAC layer, the network side equipment can bear the de-enabling command through a single MAC CE, and the network side equipment releases the MAC headers of LCID of the pre-configured resources according to the carried indication contained in the MAC CE; or (b)

The network side equipment releases the pre-configured resource corresponding to the pre-configured resource number through the pre-configured resource number which is carried in the MAC CE and releases the pre-configured resource.

And the release mode is three: releasing the pre-configured resources through RRC signaling;

and the network side equipment reconfigures the preconfigured resources with the same preconfigured resource numbers through RRC signaling, and releases the enabled preconfigured resources with the same preconfigured resource numbers.

And the release mode is four: releasing the pre-configured resource through a new PDCCH command for activating the pre-configured resource;

the network side activates the new resource configuration through the new PDCCH order of activating the pre-configured resources with the same pre-configured resource number, and it can be understood that when the new pre-configured resources are activated, the pre-configured resources activated and enabled in the pre-configured resource number before are released.

For example, as shown in fig. 15, the network side device configures a resource of the preconfigured resource type 2 with the preconfigured resource number of 2 for the terminal, activates the resource through a PDCCH command, the terminal sends data on the preconfigured resource, when the network side device configures a new set of preconfigured resources for the terminal, and the preconfigured resource number of the preconfigured resources is also 2, the network side device sends a PDCCH command for activating the preconfigured resources which are newly configured to the terminal, releases the currently activated and enabled resource with the preconfigured resource number of 2, and determines the new preconfigured resources according to the PDCCH command for activating the preconfigured resources newly.

It should be noted that "new" in the PDCCH order for activating the pre-configured resource may be understood as a PDCCH order sent by the network side device after the PDCCH order for activating the existing pre-configured resource, and the new pre-configured resource determined according to the PDCCH order for activating the new pre-configured resource may be the same as or different from the configuration of the pre-configured resource.

The fifth release mode is: releasing the pre-configured resources through a PDCCH command releasing the pre-configured resources;

the network side equipment releases the resources of the pre-configured resource type 2 configured for the terminal through the PDCCH command carrying the pre-configured resources.

The following is illustrated by way of example:

example 1: configuration and enabling of a pre-configured resource type 1 based on Uu port;

network side:

step 1: the network side equipment sends RRC signaling to the terminal, wherein the RRC signaling comprises part or all of the following steps: the configuration information of the pre-configured resources such as the time starting point of the first pre-configured resource, the time frequency resource position, the transmission format, the number of pre-allocated continuous resources in a pre-configured resource period, etc., if the RRC signaling does not contain the indication of the number of continuous resources, the protocol may define the number of continuous resources in the pre-configured resource period.

Step 2: the network side equipment receives uplink data sent by the terminal on the pre-configured resource, and determines the pre-configured resource used by the terminal for sending the first data packet by the following method:

determining a first mode: determining the used preconfigured resources according to the maximum value of the sending power of the terminal;

the network side equipment determines the sending power of the terminal on the preconfigured resource according to the power detection, determines the maximum sending power, namely the sending power of the terminal at the resource is higher than other preconfigured resources, and determines the resource to be used by the terminal for sending the first data packet. Further, the network side device may determine the preconfigured resources used by the terminal according to whether the received uplink data can decode the data packet.

And a second determination mode: according to the indication information in the data packet;

the terminal carries indication information in the data packet, the network side equipment receives the data packet reported by the terminal, and determines a preconfigured resource used by the terminal for sending the first data packet according to the indication information carried in the data packet. The indication information is carried in the MAC layer, and may be a single MAC CE or a MAC sub-header.

Step 3: the network side equipment enables the resources with the same positions as the resources used by the terminal for sending the first data packet in the preconfigured resource period;

the network side equipment determines the resource position of the first data packet sent by the terminal through the mode, and uses the resource of the received data packet as a starting point to enable the resource at the same position in each preconfigured resource period, other resources in the same preconfigured resource period fail to the terminal, namely only one enabled resource in one preconfigured resource period can be configured for other terminals to use, and the failed resource can be dynamically scheduled for the terminal to use.

Step 4: the network side equipment receives the uplink data of the terminal on the resources enabled in each preconfigured resource period.

Terminal side:

Step 1: the terminal receives RRC signaling sent by the network side equipment, and determines configuration of the pre-configured resources, including the number of continuous resources in a pre-configured resource period.

Step 2: when the data arrives, the terminal selects the closest resource to transmit the first data packet on a plurality of continuous resources in the preconfigured resources. Further, the terminal may further carry, in the first data packet, indication information for enabling the preconfigured resource, where the indication information is a MAC layer, may be a single MAC CE, or may be a MAC subheader including an LCID with an indication for enabling the preconfigured resource.

Step 3: the terminal takes the resource for transmitting the first data packet as the starting point of the enabled preconfigured resource, and the resource at the same position as the resource for transmitting the first data packet in each preconfigured resource period is taken as the enabled resource, and other preconfigured resources in the same preconfigured resource period are invalid.

Step 4: and the terminal performs data transmission on the enabled resources in the preconfigured resources.

Example 2: configuration and enabling of a pre-configured resource type 2 based on Uu port;

network side:

step 1: the network side equipment sends RRC signaling to the terminal, wherein the RRC signaling comprises part or all of the following steps: the configuration information of the pre-configured resources such as the time starting point of the first pre-configured resource, the time frequency resource position, the transmission format, the number of the pre-allocated continuous resources in a pre-configured resource period and the like; transmitting a PDCCH command to activate the pre-configured resource, and indicating the number of continuous resources in a period of the pre-configured resource by the following method:

Indication mode one: RRC signaling indication by configuring the pre-configured resources;

indication mode II: indication by PDCCH order activating pre-configured resources;

and the indication mode III: specified by a protocol;

step 2: the network side device receives the uplink data sent by the terminal on the preconfigured resource, and determines the preconfigured resource used by the terminal to send the first data packet through the specific step in the network side step 2 in the first embodiment, which is not described herein.

Terminal side:

step 1: the terminal receives RRC signaling and PDCCH command for activating the pre-configured resource sent by the network side equipment, determines the configuration of the pre-configured resource, comprises the number of continuous resources in a pre-configured resource period, and activates the pre-configured resource.

Step 2: when the data arrives, the terminal selects the closest resource to transmit the first data packet on a plurality of continuous resources in the preconfigured resources. Further, the terminal may further carry, in the first data packet, indication information that enables the pre-configured resource, where the indication information is carried on the MAC layer, and may be a single MAC ce or a MAC subheader.

Example 3: configuration and enabling of pre-configured resource type 1 based on a sidelink interface;

network side:

step 1: the network side equipment sends RRC signaling to the terminal, and configures pre-configured resources on a sidelink interface for the sending terminal, wherein the RRC signaling comprises part or all of the following steps: the configuration information of the pre-configured resources such as the time starting point of the first pre-configured resource, the time frequency resource position, the transmission format, the number of pre-allocated continuous resources in a pre-configured resource period, etc., if the RRC signaling does not contain the indication of the number of continuous resources, the protocol may define the number of continuous resources in the pre-configured resource period.

Step 2: the method comprises the steps that the network side equipment receives indication information about the enabled pre-configured resources sent by the sending terminal, determines the enabled resources in the pre-configured resources, wherein only one activated resource exists in each pre-configured resource period, other pre-configured resources are invalid, and the invalid resources can be configured for other terminals or can be dynamically scheduled for the terminals.

And the transmitting terminal:

step 1: the sending terminal receives the RRC signaling sent by the network side equipment, and determines the configuration of the pre-configured resources on the sidelink interface, wherein the configuration comprises the number of continuous resources in a pre-configured resource period.

Step 2: when the data arrives, the sending terminal selects the transmission on the closest resource sending sidelink on a plurality of continuous resources in the pre-configured resources. In one possible implementation manner, the sending terminal may send, to the network side device through the Uu interface, indication information that enables the preconfigured resource, where the indication information may be a single Uu-based MAC CE, and the MAC CE carries a resource number indicating a resource enabled in a preconfigured resource period in the preconfigured resource. For example, if the enabled resource is the first resource in the preconfigured resource period, the MAC CE carries indication information with a resource number of 0; if the enabled resource is the second resource in the preconfigured resource period, the MAC CE carries the indication information with the resource number of 1, and so on. It should be noted that the numerals are merely examples, and the present invention is not limited to the numerals.

Step 3: the terminal takes the resource for transmitting the first sidelink transmission as the starting point of the enabled preconfigured resource, the resource at the same position as the resource for transmitting the first sidelink transmission in each preconfigured resource period is taken as the enabled resource, other preconfigured resources in the same preconfigured resource period are invalid, and the terminal performs the sidelink transmission on the enabled resource in the preconfigured resources.

The receiving terminal:

the receiving terminal has two alternative transmission modes, one is that the sending terminal sends SCI indication information to the receiving terminal when transmitting data each time, and the receiving terminal determines the resource position where the sidelink transmission needs to be received and/or the resource position where the sidelink transmission is received next time according to the received SCI indication information, and in the mode, the receiving terminal does not see the pre-configured resource.

Another way is: the receiving terminal receives configuration information of pre-configured resources of a sidelink interface sent by the network side equipment or the sending terminal, determines a plurality of continuous resources in a pre-configured resource period, and receives data based on the pre-configured resources.

Example 4: configuration and enabling of pre-configured resource type 2 based on a sidelink interface;

network side:

Step 1: the network side equipment sends RRC signaling to the terminal, and configures pre-configured resources on a sidelink interface for the sending terminal, wherein the RRC signaling comprises part or all of the following steps: the configuration information of the pre-configured resources such as the time starting point of the first pre-configured resource, the time frequency resource position, the transmission format, the number of the pre-allocated continuous resources in a pre-configured resource period and the like; transmitting a PDCCH command to activate the pre-configured resource, and indicating the number of continuous resources in a period of the pre-configured resource by the following method:

and the indication mode III: specified by a protocol;

And the transmitting terminal:

step 1: the transmitting terminal receives RRC signaling and PDCCH command for activating the pre-configured resources, which are transmitted by the network side equipment, determines the configuration of the pre-configured resources on the sidelink interface, and comprises the number of continuous resources in a pre-configured resource period, and activates the pre-configured resources.

The receiving terminal:

Example 5: implicit de-enablement of pre-configured resource type 1 based on Uu port;
