Description

Method, device and system for resource scheduling

Technical field

The present invention relates to the field of wireless communication technologies, and in particular, to a method, an apparatus, and a system for resource scheduling.

Background technique

With the rapid development of wireless communication and the generation of ultra-high-speed services (such as high-definition video), the load of wireless communication networks is getting heavier and heavier. How to reduce the load on the network has become a hot topic of research. Device to Device (D2D) technology came into being. In this device direct communication mode, the terminal and the terminal can communicate directly without the need to forward through the base station, and share the data load of the base station. D2D communication can better utilize spectrum resources, improve spectrum utilization and data rate, and at the same time reduce the burden on the base station.

In D2D communication, whether it is D2D device discovery or D2D device communication, resource allocation is generally divided into two modes. The first is to allocate resources through a base station or a relay station, and the second is to send UEs from a resource pool through competition. Get the sending resource. When the resource allocation is performed by the first method, for example, when the resource is allocated by the base station, the base station sends the resource to the sender UE by using the Downlink Control Information (DCI) format5. The simple field format of DCI format5 is shown in Table 1:

Table 1: DCI format 5 fields

The sender UE receives the scheduling signaling sent by the base station, and sends a Scheduling Assignment (SA) and data to the receiver UE on the corresponding resource, and carries the related information of the data in the SA. The format of the SA is edge chain control information ( Sidelink Control Information (SCI) format 0. SCI format 0 The simple field format is shown in Table 2:

Table 2: SCI format 0 field

The receiving UE blindly checks the SA, finds the resource for transmitting data according to the SA, and then receives the data.

The scheduling signaling DCI format5 of the resource sent by the base station to the D2D sender UE is the same as the most of the fields in the SCI format 0 sent by the D2D sender UE to the receiver UE, such as frequency hopping, resource block allocation, and time domain resources. Fields such as drawings. Corresponding to the D2D sender UE forwarding the scheduling instruction sent by the base station. This causes an artificial delay, and in the process of forwarding control signaling, it also causes the cost to double.

detailed description

The technical solution of the present invention will be further described in detail below through the accompanying drawings and embodiments.

The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

A resource scheduling method provided by an embodiment of the present invention corresponds to a wireless communication system. The system mainly includes a base station, a first terminal, and a second terminal. The base station includes a NodeB, an eNodeB, a Pico, a Femto, a Home eNB, a Relay base station, or a relay terminal having a base station function. The first terminal and the second terminal may each be one or more. The scenario that can be applied to the system may include Device to Device (D2D) of the Long Term Evolution-Advanced Release-12/13 (LTE-A Rel-12/13). Scenes, LTE-A Rel-14 V2X (Vechicle-to-Everyting), D2D, M2M (Machine to Machine) and other scenarios. Certainly, these scenarios are only described in the embodiments of the present invention, but the present invention is not limited to these scenarios. For other application scenarios in which a communication connection can be established between the first terminal and the second terminal, no work is done here. limited.

The process of performing a communication connection between the base station, the first terminal, and the second terminal may refer to a method flow diagram respectively executed by each component in the wireless communication system introduced in the following.

FIG. 1 is a schematic flowchart 100 of a resource scheduling method according to Embodiment 1 of the present invention. As shown in FIG. 1 , the method step is performed by the first terminal, and the specific method steps are as follows:

Step 110: Receive a first message sent by the base station, where the first message carries the first ID information.

Specifically, the base station may be configured by a physical downlink control channel (Physical Downlink Control Channel, PDCCH for short), a Physical Downlink Shared Channel (PDSCH), or a Radio Resource Control (RRC). A message is sent to the first terminal.

The first ID information is ID information of the first terminal or other ID information except the ID information of the first terminal. And other ID information except the ID information of the first terminal may include: ID information of the second terminal, or ID information shared by a terminal and a second terminal, or public ID information other than the ID information of the first terminal and the ID information of the second terminal.

Step 120: Receive a first scheduling instruction that is sent by the base station to perform scrambling according to the first ID information.

The first scheduling instruction may be received by the second terminal, and the first scheduling instruction carries the indication information of the first resource.

Specifically, when the base station sends the first scheduling instruction to the first terminal, the second terminal may also acquire the first scheduling instruction, where the first scheduling instruction is the first scheduling instruction that is scrambled according to the first ID information. Of course, the first ID information here is usually ID information other than the first terminal. On the other hand, if the first ID information is the ID information of the first terminal, the base station naturally does not need to send it to the first terminal but to the second terminal. When the base station sends the ID information of the first terminal to the second terminal, the first terminal can also know the existence of the second terminal.

It should also be understood that the base station sends the first message to the first terminal or the first message to the second terminal, in order to enable the first terminal and the second terminal to clarify the existence of the other party. Therefore, if the first message carries the ID information of the first terminal, it can be directly sent to the second terminal, and if the ID information of the second terminal is carried, it is directly sent to the first terminal. And if it is ID information other than the ID information of the first terminal and the ID information of the second terminal, the base station needs to simultaneously transmit the first message to the first terminal and the second terminal.

The first scheduling instruction sent by the base station to the first terminal and the second terminal may be carried on the first carrier, and the first resource indicated by the first scheduling instruction may be a resource on the first carrier, or may be a resource on the second carrier. . The second carrier may be an unlicensed carrier. The first scheduling instruction may further include the second resource indication information, where the second resource is used to send the control signaling, and the second resource may be the resource on the first carrier, or the resource on the second carrier, or may be the first The resource on the three carriers, that is, the second resource, may be located in the carrier that sends the first scheduling instruction, or in the carrier that sends the data, and may also be located in other carriers. The third carrier may be an unlicensed carrier. Optionally, the second carrier and the third carrier may be the same carrier.

Specifically, when the first ID information is the ID information of the first terminal, the first scheduling instruction sent by the base station to perform scrambling according to the ID information of the first terminal is received.

Further, when the second terminal is multiple, the first field included in the first scheduling instruction is used to instruct the first terminal to use the first resource to the one or more second terminals of the multiple second terminals. send data.

And when the first ID information is the ID information of the second terminal or the ID information shared by the first terminal and the second terminal, or is the public ID information other than the first terminal and the second terminal ID information, In the case, if the number of the first terminals is multiple, the first scheduling instruction includes a second field, where the first field is used to indicate that one or more of the multiple first terminals send data to the second terminal by using the first resource. .

For example, when the first ID information is the ID information of the second terminal, a certain field is set in the scheduling instruction scrambled by the ID information of the second terminal, to indicate that the resource is allocated to the multiple first terminals. One or more first terminals.

Similarly, when the first ID information is the ID information shared by the first terminal and the second terminal, or the public ID information other than the ID information of the first terminal and the ID information of the second terminal, the shared A certain field is set in the scheduling instruction scrambled by the ID information or the public ID information, indicating that the resource is allocated to one or more of the plurality of first terminals.

It should be understood that when the base station allocates the first resource to the plurality of first terminals, that is, the plurality of first terminals simultaneously send data to the second terminal on the first resource. Rather than saying that the first resource is allocated in multiple copies, each terminal transmits data on each of the sub-resources.

If at least two of the plurality of first terminals respectively send data to one of the second terminals, at least two of the first terminals may send the same data to the second terminal, or separately send different data to the second terminal. .

It should be understood that if at least two of the plurality of first terminals respectively send the same data to the second terminal, the purpose is that in the following second embodiment, the second terminal uploads the data sent by the first terminal to the base station. At the same time, it can provide protection, that is, improve the accuracy of data transmission. The data sent by the at least two first terminals to the second terminal is the same data, and when the second terminal sends the data to the base station, at least one of the data received by the base station is accurate. The probability is relatively large, or the data sent by at least two first terminals is combined to obtain a complete data, so that the accuracy of sending data can be improved.

Similarly, if at least two of the plurality of first terminals respectively send different data to the second terminal, the second terminal may package and send data sent by different first terminals to the base station, which may save resources. .

In another case, when the first terminal is one and the second terminal is plural.

If the first ID information is the ID information of the second terminal, or the ID information shared by the first terminal and the second terminal, or the public ID information, the second field is used to indicate that the first terminal uses the first resource to multiple One or more second terminals in the second terminal transmit data.

Similar to the first terminal in the foregoing, when the second terminal is multiple, the first terminal is also on the first resource, and simultaneously sends data to the multiple second terminals. For details on how to send data, see the content described in step 140.

In addition, when the first terminal or the second terminal is multiple, in this step, the first scheduling instruction sent by the base station to perform scrambling according to the first ID information is received. The first ID information herein will not simply refer to the ID information of a certain first terminal or the ID information of the second terminal, but the group ID information of the first terminal group or the group ID information of the second terminal group. The group ID information of the first terminal group is different from any one The ID information of the ID information of a terminal is similar, that is, the group ID information of the second terminal group is different from the ID information of any one of the second terminals. Certainly, the group ID information of the first terminal group or the second terminal group is determined according to actual conditions.

When the first terminal sends data to the second terminal, the transmit power is first calculated.

Specifically, the transmit power may be calculated according to the path loss of the first terminal to the second terminal, and then the first resource is used to send data to the second terminal by using the transmit power.

When the number of the second terminals is multiple, the calculation of the path loss is to calculate the transmission power according to the path loss of the second terminal determined by the first terminal to the plurality of second terminals. The method for calculating the path loss and the transmission power in detail is a prior art and will not be described here.

Step 130: Acquire a first resource according to the indication information of the first resource, and send data to the second terminal by using the first resource.

Specifically, it can be seen from step 120 that, according to the scheduling instruction, the time-frequency location of the first resource can be determined, the first resource is obtained, and which one or which first terminals use the first resource, and to which second terminal send data. In this step, the determined first terminal uses the resource to transmit data to the one or more second terminals determined in step 120.

When the determined first terminal sends data to one or more of the plurality of second terminals by using the first resource, the following situations are specifically included.

In the first case, the first terminal sends different data to at least two of the plurality of second terminals, where different data is a subset of data that the first terminal needs to send, and all subsets constitute The complete set of data that the first terminal needs to send, and there is no intersection between multiple subsets. In other words, the first terminal divides all the data to be transmitted into several parts, and each of the second terminals that need to receive data receives different data, but the data is exactly the data to be sent by the first terminal. All.

Of course, there are also special cases. When the first terminal determines to send data to one of the plurality of second terminals, then there is no doubt that all the data of the first terminal is transmitted.

In another case, when the first terminal sends data to all the second terminals of the plurality of second terminals, the data received by each second terminal is all data sent by the first terminal. Alternatively, it may be part of the data sent by the first terminal, but the data sent by the first terminal to all the second terminals of the plurality of second terminals are the same data.

The embodiment of the present invention provides a method for resource scheduling. Before receiving the resource allocation by the base station, the first terminal first receives the first message, and the first terminal and the second terminal know the ID of the other party through the first message. Then receive The scheduling signaling that carries the resource indication information sent by the base station, and the second terminal can also listen to the scheduling signaling. When the first terminal sends data to the second terminal by using the first resource, the first terminal does not need to forward the scheduling information to the second terminal. The second terminal also does not need to blindly check the SA to determine whether it needs to receive the data sent by the first terminal. Thereby, the artificial delay can be reduced, and at the same time, since the process of forwarding the scheduling information is omitted, the overhead is greatly saved.

2 is a schematic flowchart 200 of another resource scheduling method according to Embodiment 2 of the present invention. The method is corresponding to the first embodiment, and the method is performed by the second terminal, as shown in FIG. 2 .

Step 210: Receive a first message sent by a base station. Specifically, the base station may send the first message to the second terminal by using a PDCCH, a PDSCH, or an RRC. The second terminal receives the first message. The first message carries the first ID information, where the first ID information is ID information of the first terminal or other ID information except the ID information of the first terminal. The ID information other than the ID information of the first terminal may include: ID information of the second terminal, or ID information shared by the first terminal and the second terminal, or ID information of the first terminal and an ID of the second terminal. Public ID information outside of the information.

Step 220: Receive a first scheduling instruction that is sent by the base station to perform scrambling according to the first ID information.

Specifically, the first scheduling instruction sent by the base station to the first terminal and the second terminal may be carried on the first carrier, where the first resource indicated by the first scheduling instruction may be a resource on the first carrier, or may be a second carrier. Resources on. The second carrier may be an unlicensed carrier. The first scheduling instruction may further include the second resource indication information, where the second resource is used to send the control signaling, and the second resource may be the resource on the first carrier, or the resource on the second carrier, or may be the first The resource on the three carriers, that is, the second resource, may be located in the carrier that sends the first scheduling instruction, or in the carrier that sends the data, and may also be located in other carriers. The third carrier may be an unlicensed carrier. Optionally, the second carrier and the third carrier may be the same carrier. Specifically, when the first ID information is the ID information of the first terminal, the first scheduling instruction sent by the base station to perform scrambling according to the ID information of the first terminal is received.

Further, when there are multiple second terminals, the first scheduling instruction includes a first field, and one or more of the plurality of second terminals respectively determine, according to the indication of the first field, that the user needs to receive The data sent by the first terminal on the first resource.

And when the first ID information is the ID information of the second terminal, or the ID information shared by the first terminal or the second terminal, or the public ID information other than the first terminal and the second terminal ID information, For a variety of situations.

In one case, if the number of the first terminals is multiple, the first scheduling instruction includes a second field, and the second terminal determines to receive one or more of the multiple first terminals according to the indication of the second field. The data transmitted by the first terminal using the first resource.

For example, when the first ID information is the ID information of the second terminal, a certain field is set in a field of the scheduling instruction scrambled by the ID information of the second terminal, and when the second terminal receives the scheduling instruction, according to An indication of the field in the scheduling instruction determines to receive data transmitted by one or more of the plurality of first terminals.

Similarly, when the first ID information is the ID information shared by the first terminal and the second terminal or is the public ID information, a field is set in a field of the scheduling instruction scrambled by the shared ID information or the public ID information, When the second terminal receives the scheduling instruction, according to the field indication, it may be determined to receive data sent by one or more of the plurality of first terminals.

It should be noted that when the base station allocates the first resource to the multiple first terminals, that is, the multiple first terminals simultaneously send data to the second terminal on the first resource. Rather than saying that the first resource is allocated in multiple copies, each terminal transmits data on each of the sub-resources. If at least two first terminals of the plurality of first terminals respectively send data to one second terminal, at least two first terminals may send the same data to the second terminal, or separately send different data to the second terminal.

Therefore, the second terminal may receive, according to the indication of the second field, the data that is simultaneously sent by the at least two first terminals of the multiple first terminals on the first resource, specifically, the second terminal receives at least two Different data transmitted by each of the first terminals in the first terminal, or the second terminal receives the same data transmitted by each of the at least two first terminals.

It should be understood that if at least two of the plurality of first terminals respectively send the same data to the second terminal, the purpose is that, in the following, when the second terminal sends the data sent by the first terminal to the base station, the protection may be provided. That is to improve the accuracy of data transmission. The data sent by the at least two first terminals to the second terminal are all the same data, and when the second terminal sends the data to the base station, the data received by the base station has at least one first terminal. The accuracy of the data is relatively large, or the data sent by at least two first terminals is combined to obtain a complete data, so that the accuracy of the transmitted data can be improved.

If the first ID information is the ID information of the second terminal, the shared ID information, or the public ID information, one or more of the plurality of second terminals may determine the need according to the second field indication. Receiving data sent by the first terminal using the first resource.

In another case, when the first ID information is the ID information of the second terminal, or the shared ID information, or the public ID information, and the number of the first terminal and the number of the second terminal are multiple The one or more second terminals of the plurality of second terminals may determine, according to the second field indication, which one of the plurality of first terminals needs to receive data sent by the first resource.

In addition, when the first terminal or the second terminal is multiple, in this step, the first scheduling instruction sent by the base station to perform scrambling according to the first ID information is received. The first ID information herein will not simply refer to the ID information of a certain first terminal or the ID information of the second terminal, but the group ID information of the first terminal group or the group ID information of the second terminal group. The group ID information of the first terminal group is ID information different from the ID information of any one of the first terminals. Similarly, the group ID information of the second terminal group is different from the ID information of any one of the second terminals. Certainly, the group ID information of the first terminal group or the second terminal group is determined according to actual conditions.

Step 230: Acquire a first resource according to the indication information of the first resource, and receive data sent by the first terminal on the first resource.

Further, when the data of the first terminal needs to be uploaded to the base station, if the first terminal has a limitation condition such as insufficient power or insufficient transmission power, the second terminal may forward the data and upload it to the base station.

Therefore, after the second terminal receives the data sent by the first terminal, the method may further include steps 240-250.

Step 240: Receive a second scheduling instruction sent by the base station, where the second scheduling instruction carries the third resource indication information.

Step 250: Acquire a third resource according to the third resource indication information, and upload the data sent by the first terminal to the base station on the third resource.

It should be noted that, in step 240, if the base station sends a second scheduling instruction to the second terminal, it may send a scheduling instruction to one or more second terminals. And the one or more second terminals receive the second scheduling finger In order to determine the specific requirements of the data that need to be uploaded according to the second scheduling instruction.

Specifically, the method includes: receiving, by the second terminal, at least two or all of the second terminals, the second scheduling instruction sent by the base station, where the second scheduling instruction includes a third field, The data sent by the terminal is uploaded to the base station, where the second scheduling instruction is a scheduling instruction that is scrambled according to the second ID information, where the second scheduling instruction carries the third resource indication information, and the second ID information is part of the second terminal. ID information or ID information of all second terminals.

When the second scheduling instruction indicates that the at least two second terminals are on the third resource, and the data sent by the first terminal is uploaded to the base station, the data uploaded by each of the at least two second terminals is the first terminal. A subset of the transmitted data, wherein all subsets constitute a complete set of data transmitted by the first terminal, and there is no intersection between each subset.

When the second scheduling instruction indicates that all the second terminals of the plurality of second terminals are on the third resource, and the data sent by the first terminal is uploaded to the base station, all the data sent by the second terminal are all sent by the first terminal. data. Alternatively, it may be part of the data sent by the first terminal, but the data sent by the first terminal to all the second terminals of the plurality of second terminals are the same data.

When at least two second terminals respectively transmit a part of data of the data transmitted by the first terminal, the uploading efficiency can be improved. If all the second terminals are uploaded to all the data sent by the first terminal, the accuracy of data uploading can be improved.

The embodiment of the present invention provides a method for resource scheduling. Before receiving the resource allocation by the base station, the first terminal first receives the first message, and the first terminal and the second terminal know the ID of the other party through the first message. Then, the scheduling signaling that carries the resource indication information sent by the base station is received, and the second terminal can also listen to the scheduling signaling. When the first terminal sends data to the second terminal by using the first resource, the first terminal does not need to forward the scheduling information to the second terminal. The second terminal also does not need to blindly check the SA to determine whether it needs to receive the data sent by the first terminal. Thereby, the artificial delay can be reduced, and at the same time, since the process of forwarding the scheduling information is omitted, the overhead is greatly saved.

Hereinafter, embodiments of the present invention provide specific examples of interactions between a base station, a first terminal, and a second terminal in a wireless communication system. details as follows:

FIG. 3 is a schematic diagram 300 of a signaling flow interaction of a resource scheduling method according to Embodiment 3 of the present invention. In FIG. 3, the first ID and the second terminal are both set, and the first ID information carried by the base station to the first terminal is the ID information of the first terminal. When the base station sends the first message to the first terminal, the second terminal may also receive the first message sent by the base station to the first terminal. Here, the purpose of simultaneously transmitting the first message to the first terminal and the second terminal is to let the first terminal and the second terminal determine the existence of the other party.

The interaction steps between the three are as follows:

Step 310: The base station sends a first message, where the first message carries the first ID information.

Specifically, the first message is that the base station can send to the first terminal by using a PDCCH, a PDSCH, or an RRC. The first ID information is ID information of the first terminal or other ID information except the ID information of the first terminal. The ID information other than the ID information of the first terminal may include: ID information of the second terminal, or ID information shared by the first terminal and the second terminal, or ID information of the first terminal and an ID of the second terminal. Public ID information outside of the information.

It should be noted that, because the first message carries the first ID information, in this embodiment, the first ID information itself is the ID information of the first terminal, so the base station may skip sending the first message to the first message. The steps of a terminal. Instead, the base station sends a first message to the second terminal.

Step 320: The second terminal receives the first message sent by the base station.

Specifically, when the second terminal receives the first message sent by the base station, the ID information of the first terminal is obtained.

Step 330: The base station sends a first scheduling instruction that is scrambled according to the first ID information to the first terminal, where the second terminal may also receive the first scheduling instruction, and the first scheduling instruction carries the first resource indication information.

Specifically, the first scheduling instruction sent by the base station to the first terminal may be carried on the first carrier, and the first resource indicated by the first scheduling instruction may be a resource on the first carrier or a resource on the second carrier. The second carrier may be an unlicensed carrier. The first scheduling instruction may further include the second resource indication information, where the second resource is used to send the control signaling, and the second resource may be the resource on the first carrier, or the resource on the second carrier, or may be the first The resource on the three carriers, that is, the second resource, may be located in the carrier that sends the first scheduling instruction, or in the carrier that sends the data, and may also be located in other carriers. The third carrier may be an unlicensed carrier.

In this embodiment, the first scheduling instruction is scrambled according to the ID information of the first terminal, so that the default first resource of the base station is used when the first terminal sends data.

More specifically, it should be that the base station transmits a first scheduling instruction that is scrambled according to the ID information of the first terminal to the first terminal, and the second terminal can monitor and receive the scheduling instruction sent by the base station to the first terminal. Determining a first resource allocated by the base station to the first terminal, a format in which the first terminal transmits data, and the like. The specific format is similar to the DCI format 5 field format and the SCI format0 field format introduced in the background art, and details are not described herein again.

When the base station sends the first scheduling instruction to the first terminal, the second terminal may receive the first scheduling instruction sent by the base station to the first terminal, thereby determining which first terminal needs to receive the data. However, among the scheduling instructions sent by the base station, only part of the scheduling information is utilized by the second terminal (for example, the back In the DCI format 5, which is the same as the field in the SCI format 0, the other control signaling (for example, other control signaling in the SCI format0) needs to be resent to the second terminal by the first terminal. Therefore, optionally, in the first scheduling instruction, the second resource indication information may be further included, the second resource is obtained according to the second resource indication information, and the control signaling is sent to the second terminal on the second resource. . The second resource is sent on the third carrier, and the third carrier is also an unlicensed carrier. Further, the second carrier may be the same carrier as the third carrier, that is, the first resource and the second resource are sent to the first terminal on the same carrier.

Step 340: The first terminal receives the first scheduling instruction, where the first scheduling instruction carries the first resource indication information.

Specifically, after receiving the first scheduling instruction, the first terminal may determine the location of the first resource according to the first resource indication information, thereby acquiring the first resource, and sending data to the second terminal on the first resource.

The first terminal first calculates the path loss to the second terminal, and then determines the transmit power when transmitting the data according to the path loss. And transmitting data to the second terminal using the first resource by using the transmission power.

The second terminal may be a second terminal that is closest to the first terminal, or a second terminal that is farthest from the first terminal, or a second terminal with the smallest signal measurement value, or a second terminal with the largest signal measurement value. And a second terminal having the smallest signal measurement value in the second terminal whose signal measurement value is within the set threshold range, or a second terminal having the largest signal measurement value in the second terminal whose signal measurement value is within the set threshold range .

Step 350: The second terminal receives the first scheduling instruction, and receives data sent by the first terminal on the first resource.

Specifically, when receiving the first scheduling instruction, the second terminal determines that the first terminal will send data on the first resource, and the second terminal only needs to wait for data to arrive to receive data.

When the data of the first terminal needs to be uploaded to the base station, if the first terminal has a limitation condition such as insufficient power or insufficient transmission power, the second terminal may forward the data and upload it to the base station. Specific steps may include steps 360-370.

Step 360: The base station sends a second scheduling instruction that is scrambled according to the second ID information to the second terminal, where the second scheduling instruction carries the third resource, and the second ID information is the ID information of the second terminal.

Step 370: The second terminal receives the second scheduling instruction, and sends the data sent by the first terminal to the terminal by using the third resource.

In the resource scheduling method provided by the embodiment of the present invention, before the base station allocates resources for the D2D sender UE, the base station first makes the sender UE and the receiver UE know the ID of the other party through the first message. The base station is adjusted for the D2D sender UE When the degree carries the scheduling signaling of the resource indication information, the receiver UE can also listen to the scheduling signaling. When the D2D sender UE transmits data to the receiver UE, the sender UE does not need to forward the scheduling information to the receiver. The receiver also does not need to blindly check the SA to determine whether it needs to receive the data sent by the sender UE. Thereby, the artificial delay can be reduced, and at the same time, since the process of forwarding the scheduling information is omitted, the overhead is greatly saved.

FIG. 4 is a schematic diagram of a signaling flow 400 of another resource scheduling method according to Embodiment 4 of the present invention. As shown in FIG. 4, in this embodiment, the number of the first terminal and the second terminal is the same as that in the first embodiment. The number of a terminal and the second terminal are the same, and both are one. The first message sent by the base station to the first terminal carries not the ID information of the first terminal but the ID information of the second terminal. Therefore, in this embodiment, the omitted step is that the base station sends the first message to the second terminal. In step 430, the base station sends a first scheduling instruction that is scrambled according to the first ID information to the first terminal, where the second terminal can also receive the first scheduling instruction. The first resource indication information is carried in the scheduling instruction, and the first resource is obtained according to the first resource indication information. Moreover, the first scheduling instruction includes a field, where the field is used to indicate that the first resource is used by the first terminal to send data. The other steps are the same as or similar to those in the first embodiment, and are not described here.

In the fifth embodiment of the present invention, a signaling procedure of a resource scheduling method is provided. In this embodiment, the number of the first terminals is multiple, and the number of the second terminals is one. In step 510, the base station sends a first message to the first terminal and the second terminal respectively, and the first message carries other ID information except the ID information of the first terminal and the ID information of the second terminal. In step 530, the base station sends a first scheduling instruction that is scrambled according to the first ID information to the first terminal and the second terminal, where the first scheduling instruction carries the first resource indication information, according to the first resource indication information, Get the first resource. Moreover, the first scheduling instruction includes a field, which is used to indicate which of the plurality of first terminals sends the data to the second terminal by using the first resource. The other steps are the same or similar to the third embodiment, and are not described here.

In the signaling flow of the method for resource scheduling provided by the sixth embodiment of the present invention, in this embodiment, the number of the first terminals is one, and the number of the second terminals is multiple.

In step 620, the base station sends a scheduling instruction that is scrambled according to the ID information of the first terminal, where the first resource indication information is carried in the scheduling instruction, and the first resource is obtained according to the resource indication information. And, a field included in the scheduling instruction is used to instruct the first terminal to send data to one or more of the plurality of second terminals.

Correspondingly, in step 640, the first terminal will send data to the one or more second terminals on the resource, and in step 650, the one or more second terminals will send the first terminal to send on the resource. The data.

In step 660, the base station sends, to the second terminal, a second scheduling instruction that performs scrambling according to the second ID information, The second scheduling instruction carries the third resource indication information, and acquires the third resource according to the third resource indication information.

In step 670, the one or more second terminals receive the scheduling instruction, and send the data sent by the first terminal to the base station by using the third resource.

However, it should be noted that if the second terminal specified by the base station is one, the designated second terminal will upload all the data sent by the first terminal to the base station.

When the second terminal is multiple, each second terminal sends part of the data sent by the first terminal to the base station, that is, sends a subset of the data that the first terminal needs to send to the base station. And there is no intersection between each subset, and the common set of data subsets sent by all the second terminals is all the data that the first terminal needs to send.

When the base station specifies that all the second terminals are to send the data sent by the first terminal to the base station, each of the second terminals of all the second terminals uploads all the data that the first terminal needs to send to the base station.

The other steps are the same as or similar to those in the first embodiment, and are not described herein again.

The seventh embodiment of the present invention provides a signaling procedure of a resource scheduling method. In this embodiment, the number of the first terminals is one, and the number of the second terminals is also multiple. In step 710, the base station sends a first message to the first terminal and the second terminal, where the first message carries other ID information than the ID information of the first terminal and the ID information of the second terminal. And the field included in the first scheduling instruction is used to instruct the first terminal to send data to one or more of the plurality of second terminals.

The other steps are similar to the sixth embodiment and will not be described here.

It should also be understood that, in the foregoing specific embodiment, if the first terminal or the second terminal is multiple, the first terminal receives the first scheduling instruction that is sent by the base station to perform scrambling according to the first ID information. The first ID information herein will not simply refer to the ID information of a certain first terminal or the ID information of the second terminal, but the group ID information of the first terminal group or the group ID information of the second terminal group. The group ID information of the first terminal group is ID information different from the ID information of any one of the first terminals. Similarly, the group ID information of the second terminal group is different from the ID information of any one of the second terminals. Certainly, the group ID information of the first terminal group or the second terminal group is determined according to actual conditions. In the resource scheduling method provided by the embodiment of the present invention, before the base station allocates resources for the D2D sender UE, the base station first makes the sender UE and the receiver UE know the ID of the other party through the first message. When the base station schedules the scheduling signaling carrying the resource indication information for the D2D sender UE, the receiver UE can also listen to the scheduling signaling. When the D2D sender UE transmits data to the receiver UE, the sender UE does not need to forward the scheduling information to the receiver. The receiver also does not need to blindly check the SA to determine whether it needs to receive the data sent by the sender UE. Thereby, the artificial delay can be reduced, and at the same time, since the process of forwarding the scheduling information is omitted, it is also large. Great savings.

It should be noted that the signaling flowcharts of Embodiment 5 to Embodiment 7 are similar to the signaling flowcharts of FIG. 3 and FIG. 4, and specific differences have also been pointed out above. Therefore, the applicant does not draw the signaling flowcharts of Embodiments 3 to 5. The foregoing specific signaling flowchart is only the signaling flowchart of the embodiment provided by the present invention. However, the resource scheduling method provided by the present invention includes, but is not limited to, the foregoing specific implementation manner.

The third carrier may be an unlicensed carrier. Optionally, the second carrier and the third carrier may be the same carrier.

In one case, when the first ID information is the ID information of the first terminal, the first scheduling instruction is a first scheduling instruction that the base station performs scrambling according to the ID information of the first terminal.

Further, when there are multiple second terminals, the first scheduling instruction may include a first field, where the first field is used to indicate that, on the first resource, the sending unit sends one of the multiple second terminals or A plurality of second terminals transmit data.

The scheduling instruction, where the first scheduling instruction includes a second field, where the second field is used to indicate that, on the first resource, the sending unit sends data to the second terminal.

Here, the two sub-cases are also divided into two sub-cases. In the first seed case, when the second terminal is set to be multiple, the second field is used to indicate that, on the first resource, the sending unit is respectively connected to the plurality of second terminals. One or more The second terminal sends data.

In the second seed case, when the first terminal is multiple, the second field is used to indicate that the one or more of the plurality of first terminals respectively correspond to the sending unit on the first resource, and Send data to the second terminal.

And when the second field indicates that the at least two first terminals of the plurality of first terminals send data to the second terminal, the sending unit corresponding to each of the at least two first terminals respectively Specifically, the method is: sending different data to the second terminal respectively, or separately sending the same data to the second terminal.

It should be understood that if at least two of the plurality of first terminals respectively send the same data to the second terminal, the purpose is that, in the following, when the second terminal sends the data sent by the first terminal to the base station, the protection may be provided. That is to improve the accuracy of data transmission. The data sent by the at least two first terminals to the second terminal is the same data, and when the second terminal sends the data to the base station, at least one of the data received by the base station is accurate. Or combining the data sent by the plurality of first terminals to obtain complete data sent by at least two first terminals, so that the accuracy of transmitting the data can be improved.

In the second case, the first terminal is one and the second terminal is a plurality. The second field is used to indicate that, on the first resource, the sending unit separately sends data to one or more of the plurality of second terminals.

Specifically, when the second field indicates that the first terminal is on the first resource, and the data is sent to the at least two second terminals of the multiple second terminals, the sending unit is specifically configured to:
