Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Referring to fig. 1, fig. 1 is a schematic diagram of a network architecture provided in an embodiment of the present application. In fig. 1, in a conventional cellular network, a user equipment 120 and a Base Station (BS) 110 communicate, and a link between the user equipment 120 and the Base Station 110 is referred to as an Uplink (UL) or a Downlink (DL). In the physical direct communication technology or the side link communication technology (SL), the ue 120 directly communicates with the ue 130, and the link between the ue 120 and the ue 130 is called a direct link (SL). In the side link communication technology, the user equipment 120 is called a transmitting device (Transmitter User Equipment, tx UE), and the user equipment 120 is called a receiving device (ReceiverUser Equipment, rx UE).
Wherein user device 120 may transmit communication data to user device 130 based on the side link resources allocated by base station 110. And the transmission resources on the side link or the grant (SL grant) may be allocated by the base station 110 through downlink control information (Downlink Control Information, DCI), that is, the base station 110 dynamically schedules the transmission resources on the side link; or periodic resources allocated by the base station 110 through radio resource control (Radio Resource Control, RRC) signaling.
In the uplink, the ue 120 directly transmits the communication data to the bs 110, and the bs 110 can determine whether retransmission is needed according to whether decoding is successful. Since the dl transmission resources are allocated by the base station 110, after the ue 120 sends the communication data to the ue 130 based on the dl transmission resources, the ue 130 needs to wait for the ue 120 to send a Negative Acknowledgement (NACK) on the physical dl feedback channel (Physical Sidelink Feedback Channel, PSFCH), and then forward the negative acknowledgement to the base station 110 through the physical uplink control channel (Physical Uplink Control Channel, PUCCH), and the base station 110 can schedule the ue 120 to retransmit.
The network structure in the embodiment of the application may be applicable to a 5G (5 Generation) communication system, may also be applicable to a 4G communication system and a 3G communication system, and may also be applicable to various new communication systems in the future, such as 6G, 7G, and the like.

Wherein the gNB and the terminal communicate by adopting NR technology, the ng-eNB and the terminal communicate by adopting evolved UMTS terrestrial radio access (Evolved Universal Terrestrial Radio Access, E-UTRA) technology, and the gNB and the ng-eNB can be connected to a 5G core network. The base station in the embodiment of the present application further includes a device for providing a base station function in a new communication system in the future, which may be specifically determined according to an actual application scenario, and is not limited herein.

The method for transmitting the data of the side link (for convenience of description, hereinafter referred to as the method provided by the embodiment of the present application) provided by the embodiment of the present application may be applicable to a transmitting device in the side connection communication technology. Referring to fig. 2, fig. 2 is a schematic flow chart of a first procedure of an edge link data transmission method according to an embodiment of the present application. The method of transmitting the side link data shown in fig. 2 may include the following step S201.
S201, receiving a negative acknowledgement, and starting a first configuration authorization timer so as not to use the side link pre-configuration authorization in the running time of the first configuration authorization timer.
In some possible implementations, the transmitting device may transmit communication data to the receiving device based on the side link transmission resources, and the receiving device may decode the communication data and, after decoding failure, transmit a negative acknowledgement to the transmitting device over the physical side link feedback channel. Wherein a negative acknowledgement is used to indicate a failure of the receiving device to decode the communication data. The transmitting device forwards a negative acknowledgement to the base station through the physical uplink control channel to request the base station to schedule retransmission. Since the transmitting device needs a certain time from receiving the negative acknowledgement from the sidelink feedback channel to requesting the base station to schedule the retransmission based on the negative acknowledgement, in order to ensure that the transmitting device can successfully transmit the negative acknowledgement to the base station, the transmitting device may start the first configuration grant timer after receiving the negative acknowledgement so as not to use the sidelink pre-configuration grant belonging to the same hybrid automatic repeat request (Hybrid Automatic Repeat Request, HARQ) process as the sidelink transmission resource for transmitting the communication data in the running time of the first configuration grant timer.
In the embodiment of the application, the sending device starts the configuration authorization timer, which includes starting the configuration authorization timer in an unoperated state by the sending device, and restarting the configuration authorization timer by the sending device. For convenience of description, the action of starting or restarting the configuration authorization timer with respect to the transmitting device is simply referred to as starting the configuration authorization timer, and will not be described in detail below.
Referring to fig. 3, fig. 3 is a schematic diagram of a first scenario of an edge link data transmission provided in an embodiment of the present application. In fig. 3, the transmitting device starts a first configuration grant timer after receiving a negative acknowledgement sent by the receiving device over the physical side link feedback channel. The base station configures the sending equipment to start the first configuration authorization timer after receiving the negative acknowledgement through the downlink control information. Wherein the time period from when the transmitting device receives the negative acknowledgement to when the transmitting device transmits the negative acknowledgement to the base station is the running time of the first configuration grant timer. And the running time of the first configuration grant timer is configured by radio resource control signaling sent by the base station.
Optionally, the running time of the first configuration grant timer may be a time period from when the negative acknowledgement is received to when the negative acknowledgement is sent to the base station at a first preset time point, so as to ensure that the same hybrid automatic repeat request process as the transmission of the communication data is not used in a period when the base station determines that the sending device is not scheduled to retransmit or when a new side link transmission resource allocated by the base station is received. The preset time point may be determined according to an actual application scenario, which is not limited herein.
Referring to fig. 4, fig. 4 is a second flow chart of the method for transmitting data of an edge link according to the embodiment of the present application. The side link data transmission method shown in fig. 4 may include the following steps S401 to S402.
S401, receiving a negative acknowledgement, starting a first configuration authorization timer so as not to use the side link pre-configuration authorization in the running time of the first configuration authorization timer.
In some possible embodiments, the specific embodiment of step S401 may refer to the embodiment shown in step S201 in fig. 2, and will not be described herein.
S402, a negative acknowledgement is sent to the base station, and the second configuration authorization timer is started so that the side link pre-configuration authorization is not used in the running time of the second configuration authorization timer.
In some possible embodiments, after receiving the negative acknowledgement sent by the receiving device through the physical side link feedback channel, the sending device needs to forward the negative acknowledgement to the base station through the physical uplink control channel, so that the base station reallocates new side link transmission resources. Since the transmitting device is transmitting a negative acknowledgement to the base station, it takes a certain time for the base station to reallocate new side link transmission resources to the transmitting device or to determine that the base station is no longer performing retransmission scheduling. Therefore, in order to ensure that the transmitting device can successfully transmit the negative acknowledgement to the base station and ensure that the base station will not schedule the transmitting device to retransmit or receive new sidelink transmission resources allocated by the base station, the transmitting device may start the second configuration grant timer after transmitting the negative acknowledgement to the base station through the physical uplink control channel, so as not to use the sidelink pre-configuration grant belonging to the same hybrid automatic repeat request process as the sidelink transmission resources for transmitting the communication data in the operation time of the second configuration grant timer.
Referring to fig. 5, fig. 5 is a schematic diagram of a second scenario of an edge link data transmission provided in an embodiment of the present application. In fig. 5, the transmitting device may start the second configuration grant timer after transmitting a negative acknowledgement to the base station. And the second configuration authorization timer is configured by downlink control information sent by the base station, that is, the base station configures the sending device through the downlink control information, and starts the second configuration authorization timer after sending a negative acknowledgement to the base station through a physical uplink control channel. The running time of the second configuration authorization timer is a time period from a second preset time point after the start of sending the negative acknowledgement to the base station, and the sending device can be ensured to successfully send the negative acknowledgement to the base station in the running time of the second configuration authorization timer, and the base station is ensured not to schedule the sending device to retransmit or receive new side link transmission resources allocated by the base station. Wherein the running time of the second configuration grant timer is configured by radio resource control signaling sent by the base station.
Referring to fig. 6, fig. 6 is a third flow chart of the method for transmitting side link data according to the embodiment of the present application. The side link data transmission method shown in fig. 6 may include the following steps S601 to S603.
S601, receiving the side link transmission resource, and starting a third configuration authorization timer so as not to use the side link pre-configuration authorization in the running time of the third configuration authorization timer.
In some possible embodiments, the transmitting device may send communication data to the receiving device based on the side link transmission resources after receiving the side link transmission resources allocated by the base station. The sidelink transmission resource may be dynamically allocated by the base station through downlink control information, or may be a periodic resource configured by the base station through radio resource control signaling, which may be specifically determined based on an actual application scenario, and is not limited herein.
Since the transmitting apparatus takes a certain time from receiving the side link transmission resource allocated by the base station to transmitting the communication data to the receiving apparatus based on the side link transmission resource, and if the transmitting apparatus does not successfully transmit the communication data to the receiving apparatus, the transmitting apparatus uses the same hybrid automatic repeat request process as the side link transmission resource for transmitting the communication data, the communication data may be emptied. Thus, the transmitting device may start the third configuration grant timer after receiving the side link transmission resource allocated by the base station so as not to use the same hybrid automatic repeat request process as the side link transmission resource transmitting the communication data for the operation time of the third configuration grant timer.
S602, receiving a negative acknowledgement, and starting a first configuration authorization timer so as not to use the side link pre-configuration authorization in the running time of the first configuration authorization timer.
S603, sending a negative acknowledgement to the base station, and starting a second configuration authorization timer so as not to use the side link pre-configuration authorization in the running time of the second configuration authorization timer.
In some possible embodiments, the specific embodiments of steps S602 to S604 can be referred to the implementation shown in steps S401 to S402 in fig. 4, and will not be described herein.
Referring to fig. 7, fig. 7 is a schematic diagram of a third scenario of an edge link data transmission provided in an embodiment of the present application. In fig. 7, the transmitting apparatus may start the third configuration grant timer after receiving the side link transmission resources allocated by the base station, and the base station configures the transmitting apparatus to start the third configuration grant timer after receiving the side link transmission resources allocated by the base station through the downlink control information. Wherein the third configuration grant timer is run from when the base station allocated side link transmission resources are received to when communication data is transmitted to the receiving device. And the running time of the third configuration grant timer is configured by radio resource control signaling sent by the base station.
Referring to fig. 8, fig. 8 is a fourth flowchart of a method for transmitting side link data according to an embodiment of the present application. The side link data transmission method shown in fig. 8 may include the following steps S801 to S804.
S801, receiving the side link transmission resource, and starting a third configuration authorization timer so as not to use the side link pre-configuration authorization in the running time of the third configuration authorization timer.
In some possible embodiments, the specific embodiment of step S801 may refer to the implementation shown in step S601 in fig. 6, which is not described herein.
S802, transmitting communication data to a receiving device based on the side link transmission resource, and starting a fourth configuration authorization timer so as not to use the side link pre-configuration authorization in the running time of the fourth configuration authorization timer.
In some possible embodiments, after the sending device sends the communication data to the receiving device, if the sending device uses the pre-configured grant belonging to the same hybrid automatic repeat request process as the side link transmission resource for transmitting the communication data before the communication data is sent successfully or before the receiving device decodes the communication data successfully, the sending device may be caused to empty the previously sent communication data or cause the sending device to wait for a retransmission schedule for a long time. Thus, the transmitting device may start the fourth configuration grant timer after transmitting communication data to the receiving device based on the side link transmission resource so as not to use other transmission resources belonging to the same hybrid automatic repeat request process as the side link transmission resource transmitting the communication data during the operation time of the fourth configuration grant timer.
S803, receiving the negative acknowledgement, starting the first configuration grant timer so as not to use the side link pre-configuration grant during the running time of the first configuration grant timer.
S804, a negative acknowledgement is sent to the base station, and the second configuration authorization timer is started so that the side link pre-configuration authorization is not used in the running time of the second configuration authorization timer.
In some possible embodiments, the specific embodiments of steps S803 to S804 can be referred to the implementation shown in steps S602 to S603 in fig. 6, and will not be described herein.
Referring to fig. 9, fig. 9 is a schematic diagram of a fourth scenario of an edge link data transmission provided in an embodiment of the present application. In fig. 9, the transmitting device may start the fourth configuration grant timer after transmitting communication data to the receiving device based on the side link transmission resource, and the fourth configuration grant timer is configured by downlink control information transmitted by the base station, i.e., the base station configures the transmitting device to start the fourth configuration grant timer after transmitting communication data to the receiving device through the downlink control information. The fourth configuration grant timer is run from the time of sending communication data to the receiving device until the receiving device sends a negative acknowledgement indicating decoding failure, or until a certain period of time (which may be specifically determined according to the actual application scenario and is not limited herein) to ensure that the receiving device decodes successfully. And the run time of the fourth configuration grant timer is configured by radio resource control signaling sent by the base station.
In the embodiment of the application, the configuration authorization timer is set to enable the sending equipment in the side link communication to have enough time to wait for the base station to schedule retransmission, so that the transmission delay of the sending equipment and the scheduling retransmission delay are reduced, and the applicability is high.
Referring to fig. 10, fig. 10 is a fifth flowchart of an edge link data transmission method according to an embodiment of the present application. The side link data transmission method shown in fig. 10 may include the following step S101.
S101, a negative acknowledgement is sent to the base station, and a fifth configuration authorization timer is started so that the side link pre-configuration authorization is not used in the running time of the fifth configuration authorization timer.
In some possible implementations, the base station allocates an edge link transmission resource to the transmitting device, and the transmitting device transmits communication data to the receiving device based on the edge link transmission resource. And after the receiving device fails to decode the communication data, a negative acknowledgement is sent to the sending device through a physical side link feedback channel so as to indicate that the receiving device fails to decode the communication data. The transmitting device may then transmit a negative acknowledgement to the base station over the physical uplink control channel to cause the base station to allocate new side link transmission resources. Since the transmitting device is transmitting a negative acknowledgement to the base station, it takes a certain time for the base station to reallocate new side link transmission resources to the transmitting device or to determine that the base station is no longer performing retransmission scheduling. Therefore, in order to ensure that the transmitting device can successfully transmit the negative acknowledgement to the base station, and ensure that the base station does not schedule the transmitting device to retransmit or that the receiving device can receive new sidelink transmission resources allocated by the base station, the transmitting device may start the fifth configuration grant timer after transmitting the negative acknowledgement to the base station through the physical uplink control channel, so as not to use the sidelink pre-configuration grant belonging to the same hybrid automatic repeat request process as the sidelink transmission resources for transmitting the communication data in the running time of the fifth configuration grant timer.
Referring to fig. 11, fig. 11 is a schematic diagram of a fifth scenario of an edge link data transmission provided in an embodiment of the present application. In fig. 11, the transmitting device may start a fifth configuration grant timer after transmitting a negative acknowledgement to the base station. And the fifth configuration authorization timer is configured by downlink control information sent by the base station, that is, the base station configures the sending device through the downlink control information, and starts the fifth configuration authorization timer after sending a negative acknowledgement to the base station through a physical uplink control channel. The running time of the fifth configuration grant timer is a time period from a fifth preset time point after the start of sending the negative acknowledgement to the base station, and the sending device can be ensured to successfully send the negative acknowledgement to the base station in the running time of the fifth configuration grant timer, and the base station is ensured not to schedule the sending device to retransmit or receive new side link transmission resources allocated by the base station. Wherein the running time of the fifth configuration grant timer is configured by radio resource control signaling sent by the base station.
Alternatively, in the case where the fifth configuration grant timer participates, after the transmitting device receives a negative acknowledgement transmitted by the receiving device, the sixth configuration grant timer may be started so that the side link pre-configuration grant is not used during the running time of the sixth configuration grant timer. The specific embodiment of the sixth configuration authorization timer can refer to the implementation manner shown in step S201 in fig. 2, and will not be described herein.
Optionally, the transmitting device may further start a seventh configuration grant timer after receiving the side link transmission resource allocated by the base station, so that the side link pre-configuration grant is not used for a run time of the seventh configuration grant timer. Alternatively, the transmitting device may start the eighth configuration grant timer after transmitting communication data to the receiving device based on the side link transmission resource such that the side link pre-configuration grant is not used for the run time of the eighth configuration grant timer. The specific embodiment of the seventh configuration authorization timer can refer to the implementation manner shown in step S601 in fig. 6, and will not be described herein. The specific embodiment of the eighth configuration grant timer may refer to the implementation manner shown in step S802 in fig. 8, and will not be described herein again.
In the embodiment of the application, the configuration authorization timer is set to enable the sending equipment in the side link communication to have enough time to wait for the base station to schedule retransmission, so that the transmission delay of the sending equipment and the scheduling retransmission delay are reduced, and the applicability is high.
