A resource scheduling method according to an embodiment of the present invention, a resource scheduling method includes: receiving, by a remote user terminal, a secondary user terminal secondary link buffer status report; in the remote user terminal secondary link buffer status report Adding the identification information of the remote user terminal; transmitting the secondary user terminal secondary link buffer status report to the base station; forwarding the base station according to the remote user terminal secondary link buffer status report as the remote user The secondary link resource allocated by the terminal to the remote user terminal.

Referring first to FIG. 1, FIG. 1 is a schematic flowchart diagram of a resource scheduling method according to a first embodiment of the present invention. As shown in FIG. 1 , a resource scheduling method provided by the first embodiment of the present invention may include:

S101. Receive a remote user terminal secondary link buffer status report sent by the remote user terminal.

The user terminal, that is, the UE, refers to a UE that is connected to the communication network, can acquire network resources, has information sending and receiving functions, and can establish communication with other UEs, UE groups, or eNBs in the communication network, and can be a computer. , laptops and mobile phones, etc., according to the location of the UE, can be divided into remote UE, relay UE, etc.;

The relaying UE is in the network coverage of the relay scenario introduced in the 3GPP Rel-13D2D communication, and can communicate with the eNB, and report the secondary link resource buffer status report (SidelinkBSR) to the eNB to request the secondary link from the eNB. a resource (Sidelink resource) that completes communication with other UEs;

The remote UE refers to a UE that is out of the coverage of the eNB network. The current 3GPP Rel-12 cannot report the Sidelink BSR to the eNB, so that the communication between the Sidelink resource and other UEs cannot be obtained directly from the eNB.

The eNB is associated with the UE, and is responsible for radio resource management and allocation of uplink and downlink dynamic resources of the UE in the 3GPP network, and allocates appropriate resources to the UE according to the Sidelink BSR reported by the UE for communication.

The Sidelink BSR is reported by the UE to the eNB, and is used to provide the eNB with information about how much data is shared by the UE in the uplink buffer, so that the eNB allocates appropriate resources to the UE according to the Sidelink BSR for network communication; according to the send of the Sidelink BSR. The difference between the parties can be divided into the remote user terminal sub-link buffer status report and the relay user terminal sub-link buffer status report.

The remote user terminal sub-link buffer status report, that is, the remote side-link BSR, refers to the Sidelink BSR sent by the remote UE to reflect the resource request status required by the remote UE transmitting the Remote Sidelink BSR.

Optionally, in some possible implementation manners of the present invention, in a relay scenario introduced by the 3GPP Rel-13 D2D communication, since the relay UE is in the network coverage, the relay UE may directly communicate with the eNB, and The Sidelink resource can be obtained based on the eNB resource scheduling mode defined by the Rel-12, and the D2D communication with the remote UE can be established, so that the relay UE can receive the Sidelink BSR of the remote UE sent by the remote UE.

For example, in some possible implementation manners of the present invention, after the relay UE accesses the eNB, and obtains the Sidelink resource based on the eNB resource scheduling mode defined by Rel-12, and establishes D2D communication with the remote UE, if If there are two remote UEs that establish a connection with the relay UE, the two remote UEs will send a Sidelink BSR to the relay UE, and the relay UE will receive the Sidelink BSR from the two remote UEs.

S102. Add identifier information of the remote user terminal to the remote user terminal sub-link buffer status report.

The identifier information of the remote user terminal, that is, the identifier information of the remote UE, is used to uniquely identify the remote UE that sends the Remote Sidelink BSR, so that the eNB can use the unique identifier area. The remote UE of the Remote Sidelink BSR is sent.

In some possible implementation manners of the present invention, the identification information of the remote UE may be a unique number of the remote UE in the network.

For example, after the relay UE receives the Remote Sidelink BSRs sent by two different remote UEs, in order to distinguish the remote sidelink BSRs of the two remote UEs, the Remote Sidelink BSRs are separately sent and sent. The unique number of the remote UE of the Sidelink BSR, so that after receiving the Remote Sidelink BSR, the eNB can distinguish the UE that sends the Sidelink BSR.

S103. Send the remote user terminal sub-link buffer status report to the base station.

Optionally, in some possible implementation manners of the present invention, after receiving the Remote Sidelink BSR sent by the remote UE, the relay UE adds the identifier information of the remote UE and sends the Remote Sidelink BSR to the eNB.

For example, in some possible implementation manners of the present invention, after the relay UE receives the Remote Sidelink BSR sent by two different remote UEs, the remote UE is added to the Remote Sidelink BSR of each remote UE. The unique identification information is then sent to the eNB.

S104. Forwarding, by the base station, the secondary link resource allocated to the remote user terminal according to the remote user terminal secondary link buffer status report to the remote user terminal.

For example, in some possible implementation manners of the present invention, after receiving the Sidelink resource allocated by the eNB according to the Remote Sidelink BSR, the relay UE sends the Sidelink resource to the corresponding remote UE.

Optionally, in some possible implementation manners of the present invention, the Sidelink resource received by the relay UE may be a Sidelink resource allocated by the eNB to each remote UE for the remote UE that has sent the Remote Sidelink BSR.

It can be understood that, after the remote UE receives the Sidelink resource allocated by the eNB by using the relay UE, the D2D communication between the remote UE and the UE group (UE1, UE2, UE3, . . . ) can be completed.

It can be seen that, in the solution of the embodiment, the remote user terminal sends a secondary link buffer status report sent by the remote user terminal, and adds the remote user terminal to the remote user terminal secondary link buffer status report. And sending the remote user terminal sub-link buffer status report to the base station; and forwarding the sub-link allocated by the base station to the remote user terminal according to the remote user terminal sub-link buffer status report Resources to the remote user terminal. Thus, by relaying the UE, the eNB is implemented to the remote end. The allocation of the UE's Sidelink resources, that is, the D2D communication between the remote UE and the UE group outside the network coverage is realized.

Optionally, in some possible implementation manners of the present invention, the adding the identifier information of the remote user terminal in the report includes:

Parsing the remote user terminal sublink buffer status report;

Re-encapsulating the remote user terminal sub-link buffer status report.

The identifier information of the remote user terminal, that is, the identifier information of the remote UE, is used to uniquely identify the remote UE that sends the Remote Sidelink BSR, so that the eNB can separately send the Remote Sidelink BSR according to the unique identifier. End UE.

Optionally, in some possible implementation manners of the present invention, the identifier information of the remote UE is a unique number of the remote UE in the network.

It can be understood that, after the unique identification information of the remote user terminal that sends the remote sidelink BSR is added to the remote sidelink BSR, the remote sidelink BSR can be uniquely identified by the eNB to the remote UE that sends the remote sidelink BSR, so that the subsequent eNB can perform the subsequent eNB. Resource scheduling, at this time, the mode is called eNB direct scheduling mode.

For example, after the relay UE receives the Remote Sidelink BSRs of the two remote UEs, in order to distinguish the UEs that send the Sidelink BSRs, the two Remote Sidelink BSRs are first parsed, and then added to the two Remote Sidelink BSRs. Each of the remote UEs is sent to facilitate subsequent identification of the remote UEs that send the two Remote Sidelink BSRs, and then re-encapsulate the two Remote Sidelink BSRs for transmission.

Optionally, in some possible implementation manners of the present invention, the eNB that receives the eNB according to the Remote Sidelink BSR of the remote UE sends the Remote Sidelink to each of the remote UEs. The remote UEs of the BSR are respectively allocated, so that the relay UE directly forwards the Sidelink resources allocated by the eNB to the remote UE according to the Remote Sidelink BSR to the remote UE.

For example, in some possible implementation manners of the present invention, when the relay UE receives the Remote Sidelink BSR sent by the two remote UEs, if the relay UE adds the unique location of the remote UE in the two Remote Sidelink BSRs, respectively After identifying the information, send the Remote Sidelink BSR to The eNB, so that the relay UE receives the Sidelink resources allocated to the two remote UEs by the eNB, and the relay UE forwards the Sidelink resources of the two remote UEs to the corresponding remote UE.

Optionally, in some possible implementation manners of the present invention, the method further includes:

Transmitting, by the relay user terminal, a secondary link buffer status report to the base station.

It can be understood that since the relay UE also needs the Sidelink resource, the relay UE also needs to send its own Sidelink BSR to the eNB.

The transmission user sub-link buffer status report has a higher transmission priority than the remote user terminal sub-link buffer status report.

Optionally, in some possible implementation manners of the present invention, when the uplink resource is sufficient to send two types of Sidelink BSRs, the relay UE may send the Remote Sidelink BSR in parallel with the relay UE's own Sidelink BSR.

Optionally, in another possible implementation manner of the present invention, when the uplink resource is insufficient, and the remote sidelink BSR of the remote UE and the Sidelink BSR of the relay UE itself are sent, the secondary UE BSR of the relay UE is preferentially transmitted.

It can be understood that the communication of the UE itself needs to be guaranteed first, so that the SIP of the relay UE itself needs to be sent preferentially.

The embodiment of the present invention further provides a resource scheduling method, where a resource scheduling method includes: receiving a secondary user terminal secondary link buffer status report forwarded by a relay user terminal, and the remote user terminal secondary link buffer status report And including the identifier information of the remote user terminal that sends the remote user terminal secondary link buffer status report to the relay user terminal; parsing the remote user terminal secondary link buffer status report; The remote user terminal allocates a secondary link resource.

Referring to FIG. 2, FIG. 2 is a schematic flowchart of a resource scheduling method according to a second embodiment of the present invention. As shown in FIG. 2, a resource scheduling method according to a second embodiment of the present invention may include:

S201. Receive a remote user terminal secondary link buffer status report forwarded by the relay user terminal, where the remote user terminal secondary link buffer status report includes sending the remote user terminal secondary link buffer status report to the The identification information of the remote user terminal of the relay user terminal.

The user terminal, that is, the UE, refers to a UE that is connected to the communication network, can acquire network resources, has information sending and receiving functions, and can establish communication with other UEs, UE groups, or eNBs in the communication network, and can be a computer. , laptops and mobile phones, etc., according to the location of the UE, can be divided into a remote UE, a relay UE, or the like;

Optionally, in some possible implementation manners of the present invention, in the relay scenario introduced by the 3GPP Rel-13D2D communication, since the relay UE is in the network coverage, the relay UE may directly communicate with the eNB, so that the eNB The Remote Sidelink BSR of the remote UE forwarded by the relay UE may be received.

For example, in some possible implementation manners of the present invention, after the relay UE accesses the eNB, the Sidelink resource is obtained based on the eNB resource scheduling mode defined by Rel-12, and D2D communication with the remote UE is established, thereby relaying the user. The terminal receives the Remote Sidelink BSR of the remote UE, and the relay user terminal forwards the Remote Sidelink BSR to the eNB, so that the eNB receives the Remote Sidelink BSR of the remote UE forwarded by the relay UE.

S202. Parse the remote user terminal sub-link buffer status report.

It can be understood that when the eNB receives the Remote Sidelink BSR forwarded by the relay UE, it needs to be parsed first for further processing.

S203. Allocate a secondary link resource to the remote user terminal according to the analysis result.

For example, in some possible implementation manners of the present invention, when the eNB receives the relay UE, The Remote Sidelink BSR is sent to parse the Remote Sidelink BSR, and then the Sidelink resource is allocated to the remote UE that sends the Remote Sidelink BSR according to the analysis result.

It can be seen that, in the solution of the embodiment, the remote user terminal forward link buffer status report forwarded by the relay user terminal is received, and the remote user terminal secondary link buffer status report includes sending the remote user terminal. The secondary link buffer status reports the identification information of the remote user terminal to the relay user terminal; and allocates the secondary link resource to the remote user terminal according to the analysis result. Therefore, by relaying the UE, the eNB allocates the Sidelink resources of the remote UE, that is, implements D2D communication between the remote UE and the UE group outside the network coverage.

Receiving a relay user terminal sublink buffer status report sent by the relay user terminal;

Parsing the relay user terminal sublink buffer status report;

The allocating the secondary link resources to the remote user terminal according to the parsing result includes:

Allocating sub-link resources to each of the remote user terminals according to the remote user terminal sub-link buffer status report.

It can be understood that, since the relay UE needs to send the relay UE's own Sidelink BSR in addition to the Remote Sidelink BSR of the remote UE, the eNB will receive its own Sidelink BSR sent by the relay UE, so that the eNB will receive the relay. The Remote Sidelink BSR of the remote UE sent by the UE and the Sidelink BSR of the relay itself.

Optionally, in some possible implementation manners of the present invention, the Remote Sidelink BSR of the remote UE and the Sidelink BSR of the relay UE itself are simultaneously parsed, so that the UE may be allocated Sidelink resources according to the results of the two.

Optionally, in some possible implementation manners of the present invention, the Sidelink BSR of the relay UE and the Remote Sidelink BSR of the remote UE are respectively parsed, so that the UE allocates the Sidelink resource according to the analysis result of the analysis.

For example, in some possible implementation manners of the present invention, after receiving the Remote Sidelink BSR sent by the relay UE in parallel and the Sidelink BSR of the relay itself, the eNB parses the two types of Sidelink BSRs simultaneously, and resolves to the Remote. The Sidelink BSR contains a unique identifier of the remote UE, so that each Remote Sidelink BSR can be distinguished according to the identifier, and can be distinguished from the relay's own Sidelink BSR, so that each different Sidelink BSR is used for each far The end UE and the relay UE respectively allocate Sidelink resources.

In order to facilitate the better understanding and implementation of the foregoing solutions of the embodiments of the present invention, the following is exemplified in conjunction with some specific application scenarios.

Referring to FIG. 3, FIG. 3 is a schematic flowchart of a resource scheduling method according to a third embodiment of the present invention. As shown in FIG. 3, a resource scheduling method according to a third embodiment of the present invention may include:

S301. The relay user terminal receives a remote user terminal secondary link buffer status report sent by the remote user terminal.

Optionally, in some possible implementation manners of the present invention, in a relay scenario introduced by the 3GPP Rel-13 D2D communication, since the relay UE is in the network coverage, the relay UE may directly communicate with the eNB, and The Sidelink resource can be obtained based on the eNB resource scheduling mode defined by the Rel-12, and the D2D communication with the remote UE can be established, so that the relay UE can receive the remote UE sent by the remote UE. SidelinkBSR.

S302. The relay user terminal parses the sub-link buffer status report of the remote user terminal.

S303. The relay user terminal adds the identifier information of the remote user terminal to the sub-link buffer status report of the remote user terminal.

S304. The relay user terminal re-encapsulates the remote user terminal sub-link buffer status report.

It can be understood that the relay UE first needs to parse the Remote Sidelink BSR to add the identifier and re-encapsulate in the Remote Sidelink BSR.

S305. The relay user terminal sends a remote user terminal secondary link buffer status report and a relay user terminal secondary link buffer status report to the base station.

Optionally, in some possible implementation manners of the present invention, when the uplink resource is sufficient to send two types of Sidelink BSRs, the relay UE may use the Remote Sidelink BSR and the relay UE's own Sidelink. The BSR is sent in parallel.

For example, in some possible implementation manners of the present invention, after the relay UE receives the Remote Sidelink BSR sent by two different remote UEs, the remote UE is added to the Remote Sidelink BSR of each remote UE. The unique identification information is then sent to the eNB by the relay UE's own Sidelink BSR and the remote sidelink BSRs of the two remote UEs.

S306. The base station receives a relay user terminal secondary link buffer status report and a forwarded remote user terminal secondary link buffer status report sent by the relay user terminal.

S307. The base station parses the remote user terminal sub-link buffer status report and the relay user terminal sub-link buffer status report.

It can be understood that when the eNB receives the Remote Sidelink BSR forwarded by the relay UE and the Sidelink BSR of the relay UE itself, it needs to be parsed first for further processing.

S308. The base station allocates a secondary link resource to each remote user terminal according to the remote user terminal secondary link buffer status report.

Optionally, in some possible implementation manners of the present invention, the eNB is configured as each of the remote user terminals according to the remote user terminal secondary link buffer status report and the relay user terminal secondary link buffer status report, respectively. The relay user terminal allocates a secondary link resource.

Optionally, in some possible implementation manners of the present invention, the eNB performs scheduling according to the eNB resource scheduling mode defined by the Rel-12 according to the method for scheduling the Sidelink for the remote UE according to the Remote Sidelink BSR.

It can be understood that, since the relay UE adds the unique identification information of the remote UE in the Remote Sidelink BSR of the remote UE, the eNB will resolve the unique identification information of the remote UE in the Remote Sidelink BSR, so that the eNB can be based on the Remote. The Sidelink BSR allocates a Sidelink resource for each remote UE.

For example, in some possible implementation manners of the present invention, when the eNB receives the two Remote Sidelink BSRs that are relayed by the relay UE and the Sidelink BSR of the relay itself, the eNB analyzes the two types of Sidelink BSRs simultaneously. Each of the two Remote Sidelink BSRs includes a unique identifier of the remote UE, so that each Remote Sidelink BSR can be distinguished according to the identifier, and can be distinguished from the relay's own Sidelink BSR, so that each different The Sidelink BSR allocates Sidelink resources to the two remote UEs and the relay UEs respectively.

S309. The relay user terminal forwards the secondary link resource allocated by the base station to the remote user terminal according to the remote user terminal secondary link buffer status report to the remote user terminal.

For example, when the Remote Sidelink BSR includes the unique identifier of the remote UE that sends the Remote Sidelink BSR, the relay UE receives the Sidelink resource allocated by the eNB according to the Remote Sidelink BSR for each remote UE, and then forwards the Sidelink resource. To the remote UE that sent the Remote Sidelink BSR.

It can be seen that, in the solution of this embodiment, the relay user terminal receives the remote user terminal secondary link buffer status report sent by the remote user terminal; and the relay user terminal reports the secondary link buffer status of the remote user terminal. Adding the identification information of the remote user terminal to the base station; after the relay user terminal performs the foregoing marking on the secondary user terminal secondary link buffer status report, the secondary user terminal sends a secondary link buffer status report to the base station; The base station receives the sub-link buffer status report of the remote user terminal forwarded by the relay user terminal; the base station parses the sub-link buffer status report of the remote user terminal; and the base station allocates the sub-link resource to the remote user terminal according to the parsing result. After receiving the secondary link resource allocated by the base station, the relay user terminal forwards the secondary link resource allocated by the base station to the remote user terminal according to the remote user terminal secondary link buffer status report to the Remote user terminal. Therefore, by relaying the UE, the eNB allocates the Sidelink resources of the remote UE, that is, implements D2D communication between the remote UE and the UE group outside the network coverage.

The embodiment of the present invention further provides a resource scheduling method, where the resource scheduling method includes: receiving a remote user terminal secondary link buffer status report sent by at least one remote user terminal; and replacing the remote user terminal secondary link buffer a logical channel number of the status report; sending the remote user terminal secondary link buffer status report to the base station; and receiving, by the base station, the at least one remote user terminal according to the remote user terminal secondary link buffer status report The total secondary link resource performs scheduling of the total secondary link resources for the at least one remote user terminal.

Referring to FIG. 4, FIG. 4 is a schematic flowchart diagram of a resource scheduling method according to a fourth embodiment of the present invention. As shown in FIG. 4, a resource scheduling method according to a fourth embodiment of the present invention may include:

S401. Receive a remote user terminal secondary link buffer status report sent by at least one remote user terminal.

S402. Replace a logical channel number of the sub-link buffer status report of the remote user terminal.

The logical channel number, that is, the logical channel ID, is used to indicate on which logical channel a certain type of signal is transmitted. When the logical channel ID is changed, it represents the corresponding transmission logical channel change, when the logical channel of the Remote Sidelink BSR is replaced. After the ID, the remote sidelink BSR can be distinguished from the relay UE's own Sidelink BSR. However, the remote sidelink BSRs sent by different remote UEs have the same logical channel ID, that is, the Remote Sidelink BSR sent by different remote UEs cannot be distinguished. .

For example, in some possible implementation manners of the present invention, after the relay UE receives the Remote Sidelink BSR sent by two different remote UEs, all the Remote Sidelink BSRs sent by the remote UE are relayed to the relay itself. The Sidelink BSR distinguishes the logical channel ID of the Remote Sidelink BSR by a value different from the original logical channel ID, so that the logical channel of the Remote Sidelink BSR is different from the relay's own Sidelink BSR, so that the eNB can receive both of them. The Sidelink BSR distinguishes based on the logical channel ID.

Optionally, in another possible implementation manner of the present invention, after the relay UE receives the Remote Sidelink BSR sent by the remote UE, the logical channel ID of the Remote Sidelink BSR of the remote UE is assigned a new value and then sent to the eNB. .

For example, in another possible implementation manner of the present invention, after the relay UE receives the Remote Sidelink BSRs sent by the two remote UEs, the logical channel IDs of the Remote Sidelink BSRs of the two remote UEs are assigned new values. Then, the eNB is further sent to distinguish the logical channel ID of the Remote Sidelink BSR from the remote UE from the logical channel ID of the relay itself.

S404. Receive, by the base station, a total sub-link resource allocated to the at least one remote user terminal according to the remote user terminal sub-link buffer status report, and perform total deputy for the at least one remote user terminal. Scheduling of link resources.

For example, in some possible implementation manners of the present invention, after receiving the Sidelink resource allocated by the eNB according to the Remote Sidelink BSR to the at least one remote UE, the relay UE sends the Sidelink resource to the corresponding remote UE.

Optionally, in other possible implementation manners of the present invention, the Sidelink resource received by the relay UE may also be the sum of all Sidelink resources allocated by the eNB for all remote UEs that have sent the Remote Sidelink BSR.

Optionally, in some possible implementation manners of the present invention, when the relay UE scheduling eNB allocates the Sidelink resource to the at least one remote UE according to the Remote Sidelink BSR, the eNB resource scheduling mode is the same as the Rel-12-defined eNB resource scheduling mode. .

Optionally, in another possible implementation manner of the present invention, the eNB that receives the eNB according to the Remote Sidelink BSR of the at least one remote UE allocates a Remotelink resource to the remote UE for all the Remote Sidelink BSRs. And the sum of the Sidelink resources respectively allocated by the at least one remote UE, the relay UE scheduling and forwarding the eNB according to the Remote Sidelink BSR as the remote end The Sidelink resource allocated by the UE to the at least one remote UE.

Optionally, in some possible implementation manners of the present disclosure, when the relay UE schedules the Sidelink resource for the at least one remote UE, when the relay UE receives the Sidelink resource from the eNB, according to each Remote Sidelink BSR, The corresponding remote UEs schedule corresponding resources.

Optionally, in another possible implementation manner of the present invention, when the relay UE schedules the Sidelink resource for the at least one remote UE, when the relay UE receives insufficient Sidelink resources from the eNB, the priority is high. The remote UE schedules the Sidelink resource.

For example, in another possible implementation manner of the present invention, when the relay UE receives the Remote Sidelink BSR sent by the two remote UEs, if the relay UE assigns the logical channel IDs of the two Remote Sidelink BSRs to the new value. And sending the Remote Sidelink BSR to the eNB, so that the relay UE receives the sum of the Sidelink resources allocated by the eNB for the two remote UEs, if the sum of the allocated Sidelink resources at this time is insufficient to meet the requirements of the two remote UEs. If the priority of the remote UE1 is higher than that of the remote UE2, the remote UE1 is preferentially allocated with the Sidelink resource, and then the remote UE2 is allocated the Sidelink resource.

It can be seen that, in the solution of this embodiment, receiving a remote user terminal secondary link buffer status report sent by the remote user terminal; replacing the logical channel number of the remote user terminal secondary link buffer status report; The remote user terminal sub-link buffer status is reported to the base station; and the forwarding base station reports the sub-link resource allocated to the remote user terminal to the remote user according to the remote user terminal sub-link buffer status report. terminal.

However, the remote sidelink BSRs from different remote UEs cannot be distinguished, so that the subsequent eNBs can perform resource allocation according to the relay UE and the remote UE after receiving the Sidelink BSR. In this case, the mode is called the eNB indirect scheduling mode.

For example, in some possible implementation manners of the present invention, after the relay UE receives the Remote Sidelink BSRs of the two remote UEs, the Remote Sidelink BSR sent by the two remote UEs and the Sidelink sent by the relay UE are used. The BSR distinguishes the two Remote Remote Link BSRs and then replaces the Remote Sidelink BSRs sent by the two remote UEs, that is, reassigns the Remote Sidelink BSRs sent by the two remote UEs to the relay users. The logical channel ID of the Sidelink BSR of the terminal is distinguished, and then the Remote Sidelink BSR after replacing the logical channel ID is re-encapsulated for transmission.

Optionally, in some possible implementation manners of the present invention, after the replacing the logical channel number of the remote user terminal sub-link buffer status report, sending the remote user terminal sub-link buffer status report to In the eNB, the Remote Sidelink BSR of the remote UE and the Sidelink BSR of the relay itself are transmitted on different logical channels.

S501: Receive a remote user terminal secondary link buffer status report sent by at least one remote user terminal forwarded by the relay user terminal, where the remote user terminal secondary link buffer status report includes the replaced logical channel number.

Optionally, in some possible implementation manners of the present invention, introduced in 3GPP Rel-13D2D communication In the relay scenario, since the relay UE is in the network coverage, the relay UE can directly communicate with the eNB, so that the eNB can receive the Remote Sidelink BSR of the remote UE forwarded by the relay UE.

For example, in some possible implementation manners of the present invention, after the relay UE accesses the eNB, the Sidelink resource is obtained based on the eNB resource scheduling mode defined by Rel-12, and D2D communication with the remote UE is established, thereby relaying the user. The terminal receives the Remote Sidelink BSR sent by the at least one remote UE, and the relay user terminal forwards the Remote Sidelink BSR to the eNB, so that the eNB receives the Remote Sidelink BSR of the remote UE forwarded by the relay UE.

S502. Parse the remote user terminal sub-link buffer status report.

S503. Allocate a secondary link resource to the at least one remote user terminal according to the parsing result.

For example, in some possible implementation manners of the present invention, when the eNB receives the Remote Sidelink BSR forwarded by the relay UE, parses the Remote Sidelink BSR, and then sends at least one remote end of the Remote Sidelink BSR according to the parsing result. The UE allocates a Sidelink resource.

Transmitting a total of the secondary link resources to the relay user terminal, so that the relay user terminal allocates the total secondary link resource to the remote user terminal according to the remote user terminal secondary link buffer report .

For example, in another possible implementation manner of the present invention, after the eNB receives the Remote Sidelink BSR sent by the relay UE and the Sidelink BSR of the relay itself, the eNB performs parsing on the two types of Sidelink BSRs simultaneously. After the two logical channel IDs, that is, the Remote Sidelink BSR is a logical channel ID and the relay's own Sidelink BSR is a logical channel ID, the Sidelink resources are assigned to the Sidelink BSRs belonging to different logical channel IDs, that is, The Sidelink resource is allocated by its own Sidelink BSR, and the sum of the Sidelink resources is allocated to all remote UEs transmitting the Remote Sidelink BSR.

S601. The relay user terminal receives a remote user terminal secondary link buffer status report sent by at least one remote user terminal.

S602. The relay user terminal parses the sub-link buffer status report of the remote user terminal.

S603. The relay user terminal replaces a logical channel number of the sub-link buffer status report of the remote user terminal.

The logical channel number, that is, the logical channel ID, is used to indicate on which logical channel a certain type of signal is transmitted. When the logical channel ID is changed, it represents the corresponding transmission logical channel change, when the logical channel of the Remote Sidelink BSR is replaced. After the ID, the Remote Sidelink BSR can be distinguished from the relay UE's own Sidelink BSR, but the Remote Sidelink sent by different remote UEs The BSRs have the same logical channel ID, that is, they cannot distinguish the Remote Sidelink BSRs sent by different remote UEs.

It can be understood that after the logical channel number of the Remote Sidelink BSR is replaced, the Remote Sidelink BSR sent by the remote UE can be distinguished from the Sidelink BSR sent by the relay UE, but the Remote Sidelink BSR from different remote UEs cannot be performed. Differentiated, so that the subsequent eNBs perform resource allocation according to the relay UE and the remote UE after receiving the Sidelink BSR. At this time, the mode is called the eNB indirect scheduling mode.

S604. The relay user terminal re-encapsulates the remote user terminal sub-link buffer status report.

S605. The relay user terminal sends a remote user terminal secondary link buffer status report and a relay user terminal secondary link buffer status report to the base station.

Optionally, in other possible implementation manners of the present invention, when uplink resources are insufficient, When the remote sidelink BSR of the remote UE and the Sidelink BSR of the relay UE itself are relayed, the relay UE's own Sidelink BSR is preferentially transmitted.

For example, in some possible implementation manners of the present invention, when the relay UE receives the Remote Sidelink BSRs sent from two different remote UEs, and assigns the logical channel IDs of the remote sidelink BSRs of the two remote UEs After the new value is re-encapsulated, the relay UE's own Sidelink BSR and the remote sidelink BSRs of the two remote UEs are sent to the eNB.

The terminal receives the Remote Sidelink BSR sent by the at least one remote UE, and the relay user terminal forwards the Remote Sidelink BSR to the eNB, so that the eNB receives the Remote Sidelink BSR of the at least one remote UE forwarded by the relay UE.

S607. The base station parses the remote user terminal sublink buffer status report and the relay user terminal sublink buffer status report.

After the two logical channel IDs, that is, the Remote Sidelink BSR is a logical channel ID and the relay's own Sidelink BSR is a logical channel ID, the Sidelink resources are allocated to the Sidelink BSRs belonging to different logical channel IDs, that is, Relay itself The Sidelink BSR allocates the Sidelink resource and allocates the sum of the Sidelink resources to all remote UEs that send the Remote Sidelink BSR.

S608. The base station sends the total sub-link resource to the relay user terminal according to the parsing result, so that the relay user terminal allocates the total sub-link resource to the remote user terminal according to the remote user terminal sub-link buffer report.

It can be understood that when the Sidelink BSR of the relay UE and the Remote Sidelink BSR of the remote UE are different logical channel IDs, and the remote Sidelink BSRs of all the remote UEs are the same logical channel ID, the Remote Sidelink BSR cannot be distinguished. Therefore, the eNB sends the sum of the Sidelink resources allocated to all the remote UEs that send the Remote Sidelink BSR.

The relay user terminal receives the total secondary link resource allocated by the base station to the at least one remote user terminal according to the remote user terminal secondary link buffer status report, and is the at least one remote user terminal. The scheduling of the total secondary link resources is performed.

It can be understood that, because the eNB received by the relay UE sends the sum of the Sidelink resources to one of the remote UEs, the relay UE needs to complete the scheduling of the Sidelink resources according to the Remote Sidelink BSR.

Optionally, in some possible implementation manners of the present disclosure, when the relay UE scheduling eNB allocates the Sidelink resource to the remote UE according to the Remote Sidelink BSR, the eNB resource scheduling mode is the same as the Rel-12-defined eNB resource scheduling mode. .

Optionally, in some possible implementation manners of the present invention, when the relay UE is scheduled for the remote UE In the case of the Sidelink resource, when the Relaylink resource received by the relay UE from the eNB is sufficient, the corresponding resource is scheduled for the corresponding remote UE according to each Remote Sidelink BSR.

Optionally, in another possible implementation manner of the present invention, when the relay UE schedules the Sidelink resource for the remote UE, when the relay UE receives insufficient Sidelink resources from the eNB, the priority is the remote terminal with a higher priority. The UE schedules the Sidelink resource.

For example, in some possible implementation manners of the present invention, when the relay UE receives the Remote Sidelink BSR sent by the two remote UEs, if the relay UE adds the unique location of the remote UE in the two Remote Sidelink BSRs, respectively After the identification information, the Remote Sidelink BSR is sent to the eNB, so that the relay UE receives the Sidelink resources allocated by the eNB to the two remote UEs, and the relay UE forwards the Sidelink resources of the two remote UEs to the corresponding Remote UE.

It can be seen that, in the solution of this embodiment, the relay user terminal receives the remote user terminal secondary link buffer status report sent by the at least one remote user terminal; and the relay user terminal replaces the remote user terminal secondary link buffer. a logical channel number of the status report; after the relay user terminal performs the foregoing marking on the remote user terminal secondary link buffer status report, the remote user terminal sends a secondary link buffer status report to the base station; and the base station receives the relay user. a remote user terminal sub-link buffer status report sent by the at least one remote user terminal forwarded by the terminal; the base station parses the remote user terminal sub-link buffer status report; and the base station allocates a pair to the remote user terminal according to the parsing result a link resource; the relay user terminal receives the total secondary link resource allocated by the base station to the at least one remote user terminal according to the remote user terminal secondary link buffer status report, and is the at least one remote end The user terminal performs scheduling of the total secondary link resources.
