Fig. 1 is a schematic diagram of a communication system to which an embodiment of the present application is applicable. The vehicle-mounted terminals (the vehicle-mounted terminal 131 and the vehicle-mounted terminal 132) autonomously select transmission resources on the resources of the side links to perform data transmission. Optionally, the vehicle-mounted terminal may select the transmission resource randomly, or select the transmission resource through a listening or sensing manner.

To facilitate a better understanding of embodiments of the present application, the application is described in relation to D2D/V2X.

Device-to-Device communication is based on a side-link (SL) transmission technique of Device-to-Device (D2D), and thus has higher spectral efficiency and lower transmission delay, unlike conventional cellular systems in which communication data is received or transmitted via a base station. The internet of vehicles system adopts a terminal-to-terminal direct communication mode, and two transmission modes are defined in The third generation partnership project (The 3rd Generation Partnership Project,3GPP): mode a and mode B.

Mode a: the transmission resources of the terminal are allocated by the base station, and the terminal transmits data on the side links according to the resources allocated by the base station; the base station may allocate resources for single transmission to the terminal, or may allocate resources for semi-static transmission to the terminal. As shown in fig. 2, the terminal is located in the coverage area of the network, and the network allocates transmission resources for side transmission to the terminal.

Mode B: and the terminal selects one resource from the resource pool to transmit data. As shown in fig. 3, the terminal is located outside the coverage area of the cell (i.e., the terminal is located outside the coverage area of the network), and the terminal autonomously selects transmission resources in a preconfigured resource pool to perform side transmission; or as shown in fig. 2, the terminal autonomously selects transmission resources from a resource pool configured by the network to perform side transmission.

Note that, the mode a may be referred to as a mode 1, and the mode B may be referred to as a mode 2.

In 3GPP, D2D is classified into Proximity-based Services (ProSe), internet of vehicles (Vehicle to everything, V2X), and wearable devices (FeD 2D).

ProSe: device-to-device communication was studied for ProSe scenarios, which are mainly directed to public safety class traffic.

In ProSe, by configuring the position of the resource pool in the time domain, for example, the resource pool is discontinuous in the time domain, discontinuous data transmission/reception of the UE on the side link is achieved, so that the effect of power saving is achieved.

Internet of vehicles (V2X): the Internet of vehicles system researches the scenes of vehicle-to-vehicle communication, and is mainly oriented to the traffic of vehicle-to-vehicle and vehicle-to-person communication which move at a relatively high speed; in V2X, since the in-vehicle system has continuous power supply, power efficiency is not a major problem, and delay of data transmission is a major problem, so that continuous transmission and reception by the terminal device is required in system design.

Wearable device (FeD 2D): this scenario is studied for the scenario where the wearable device accesses the network through a handset, which is mainly oriented to the scenario of low movement speed and low power access. In FeD2D, the 3GPP concludes that the base station can configure discontinuous reception (Discontinuous Reception, DRX) parameters of a remote terminal through a relay terminal.

For a better understanding of the embodiments of the present application, the NR V2X related to the present application will be described.

NR V2X is not limited to broadcast scenes, but extends further to unicast and multicast scenes where V2X applications are studied. NR V2X also defines two resource grant modes, mode A/mode B, described above; further, the user may be in a mixed mode, i.e., both mode a and mode B may be used for resource acquisition. The resource acquisition is indicated by means of a sidelink grant, i.e. the sidelink grant indicates the time-frequency position of the corresponding physical sidelink control channel (Physical Sidelink Control Channel, PSCCH) and physical sidelink shared channel (Physical Sidelink Shared Channel, PSSCH) resources.

Unlike LTE V2X, NR V2X introduces feedback-based HARQ retransmissions, not limited to unicast communications, but also multicast communications, in addition to feedback-free, UE-initiated hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) retransmissions.

As in LTE V2X, in NR V2X, since the in-vehicle system has continuous power supply, power efficiency is not a major problem, and delay of data transmission is a major problem, and thus continuous transmission and reception by the terminal device is required in system design.

In order to facilitate a better understanding of the embodiments of the present application, the prior art and the problems associated with the present application will be described.

At present, if the terminal is out of network coverage, the terminal can only acquire resources in a mode B mode, namely, autonomously select resources. At this time, if the sensing result is unavailable or the resource pool of the mode B is too congested, the terminal cannot select reliable transmission resources, and can only perform random selection in the abnormal resource pool, so that the reliability cannot be guaranteed. On the other hand, when the terminal acquires the resources in the mode B, the terminal needs to continuously sense, and the power consumption can be greatly increased.

Based on the above problems, the present application proposes a resource allocation scheme, when the terminal device is out of network coverage, the terminal device can obtain reliable transmission resources through the opposite terminal, and the terminal device does not need to perform sensing operation, so that the reliability of the resources can be ensured, and the power consumption of the terminal device is reduced.

The technical scheme of the application is described in detail below through specific embodiments.

Fig. 4 is a schematic flow chart of a method 200 of wireless communication according to an embodiment of the application, as shown in fig. 4, the method 200 of wireless communication may include at least some of the following:

s210, a first terminal device determines that a target service corresponds to a first resource allocation mode; wherein the first resource allocation mode is a mode in which the second terminal device schedules the first terminal device through unicast connection.

In some embodiments, the target service may be a unicast connection service, and the first terminal device is an originating terminal of the target service, and the second terminal device is a receiving terminal of the target service.

In the embodiment of the present application, the first terminal device may also be referred to as a scheduled terminal, the second terminal device may also be referred to as a scheduled terminal, and the first resource allocation mode may also be referred to as mode 2d. In the first resource allocation mode (mode 2 d), the second terminal device schedules resource selection of the first terminal device.

In the embodiment of the present application, in the first resource allocation mode, the second terminal device may schedule the first terminal device through a unicast connection (i.e., the second terminal device may configure transmission resources for the first terminal device through a unicast connection), and the first terminal device may transmit the target service to the second terminal device based on the resources scheduled by the second terminal device.

In some embodiments, the first terminal device determines that the target traffic corresponds to the first resource allocation pattern in case the second terminal device has resource scheduling capabilities for the target traffic.

In some embodiments, the first terminal device receives first indication information sent by the second terminal device, where the first indication information is used to indicate that the second terminal device has a resource scheduling capability for the target service.

In some embodiments, the first indication information may be sent by one of:

PC5-RRC signaling, medium access control element (Media Access Control Control Element, MAC CE) signaling, sidestream control information (Sidelink Control Information, SCI) signaling.

In some embodiments, whether the second terminal device has resource scheduling capability for the target service is obtained by the first terminal device during establishment of a sidestream connection with the second terminal device.

In some embodiments, the first terminal device determines that the target service corresponds to the first resource allocation pattern according to a first condition;

wherein the first condition includes at least one of: the first terminal device is out of network coverage, the perceived result of the first terminal device is not available, and the second terminal device has resource scheduling capability for the target service.

In some embodiments, the first terminal device determines, according to a first correspondence, that the target service corresponds to the first resource allocation pattern;

wherein the first correspondence includes a correspondence between first information and at least one resource selection mode, the at least one resource selection mode includes the first resource allocation mode, and the first information includes at least one of: quality of Service (Quality of Service, qoS), service Priority (Service Priority), sidestream resource block (Sidelink Resource Block, SL-RB), destination ID (destination ID), communication type (cast type), resource pool (resource pool), geographic location area ID.

Specifically, for example, the first terminal device determines, according to the first information and the first correspondence corresponding to the first terminal device, that the target service corresponds to the first resource allocation mode.

That is, the first terminal device determines that the target service corresponds to the first resource allocation mode according to at least one of the QoS, the service priority, the side resource block, the destination identifier, the communication type, the resource pool, the geographic location area identifier and the first correspondence.

It should be noted that, the destination ID may indicate the target service, or may indicate the receiving device (i.e., the second terminal device) of the target service.

In some embodiments, the communication type (cast type) may include at least one of:

unicast communication, multicast communication, broadcast communication.

In some embodiments, the first correspondence is pre-configured or agreed upon by a protocol, or the first correspondence is configured by a first network device via a system message (e.g., a system information block (System Information Block, SIB)) or dedicated signaling.

In some embodiments, the first terminal device determines that the target service corresponds to the first resource allocation pattern according to an indication of the first network device.

In some implementations, the first terminal device sends the target traffic to the first network device through direct link terminal assistance information (sidelinkinformation) with the first terminal device within the first network device coverage and with the first terminal device in a radio resource control (Radio Resource Control, RRC) connected state; and the first terminal equipment receives second indication information sent by the first network equipment, wherein the second indication information is used for indicating that the target service corresponds to the first resource allocation mode.

Specifically, for example, the first terminal device is in the coverage of the first network device, and the first terminal device is in an RRC connected state, as shown in fig. 5, where the first terminal device sends a destination identifier 1 (destination ID 1) to the first network device through direct link terminal auxiliary information (sendlinkinformation), where the destination identifier 1 indicates a target service; after the first network device receives the destination identifier 1, the first network device may configure the first terminal device with the first resource allocation mode corresponding to the target service, as shown in fig. 5, and the first network device sends second indication information to the first terminal device through an RRC reconfiguration message (rrcrecon configuration), where the second indication information is used to indicate that the destination identifier 1 corresponds to the first resource allocation mode. And the first terminal equipment sends a resource allocation mode switching request to the second terminal equipment so as to instruct the switching of the resource allocation mode corresponding to the target service to the first resource allocation mode.

In some embodiments, the first terminal device sends third indication information to the second terminal device, where the third indication information is used to instruct the first terminal device to determine that the target service corresponds to the first resource allocation mode. That is, after the first terminal device determines that the target service corresponds to the first resource allocation mode, the first terminal device sends the third indication information to the second terminal device, so as to trigger the second terminal device to determine whether the second terminal device has the capability of activating the first resource allocation mode corresponding to the target service.

In some embodiments, the third indication information may be sent by one of:

PC5-RRC signaling, MAC CE signaling, SCI signaling.

In some embodiments, the first terminal device sends first request information to the second terminal device, where the first request information is used to request the second terminal device to perform resource scheduling on the first terminal device.

In some embodiments, the first request information may be sent by one of:

PC5-RRC signaling, MAC CE signaling, SCI signaling.

In some embodiments, the first terminal device receives first response information sent by the second terminal device, the first response information including response information for the first request information.

Specifically, for example, the response information to the first request information may be an Acknowledgement (ACK) or a negative Acknowledgement (Negative Acknowledgement, NACK).

In some embodiments, the first response information may be sent by one of:

PC5-RRC signaling, MAC CE signaling, SCI signaling, physical sidelink feedback channel (Physical Sidelink Feedback Channel, PSFCH).

In some embodiments, in a case where the response information for the first request information included in the first response information is ACK, the first response information includes a resource pool configuration corresponding to the target service. Therefore, the first terminal equipment can acquire the sending resource corresponding to the target service based on the resource pool configuration.

In some embodiments, in a case where the response information for the first request information included in the first response information is ACK, the first terminal device activates the first resource allocation mode corresponding to the target service.

In some embodiments, the first terminal device determines to deactivate the first resource allocation pattern corresponding to the target service. That is, after the first terminal device activates the first resource allocation pattern corresponding to the target service, the first terminal device may deactivate the first resource allocation pattern corresponding to the target service in some cases.

In some implementations, the first terminal device determines to deactivate the first resource allocation mode corresponding to the target service according to a second condition; wherein the second condition includes at least one of:

under the condition that the first terminal equipment is in the coverage of the first network equipment and the first terminal equipment is in an RRC connection state, the first network equipment reconfigures a resource allocation mode for the first terminal equipment;

a unicast link corresponding to the target service has radio link failure (Radio Link Failure, RLF);

the reference signal received power (Reference Signal Received Power, RSRP) of the unicast link corresponding to the target service is lower than the sidelink RSRP threshold;

the channel busy rate (Channel Busy Ratio, CBR) of the transmission resource pool corresponding to the target traffic is greater than a CBR threshold;

the first terminal equipment has a service to be transmitted with a priority higher than a priority threshold;

the first terminal device has traffic to be transmitted with a QoS above a QoS threshold.

In some implementations, the sidestream RSRP threshold is pre-configured or agreed upon, or the sidestream RSRP threshold is configured for the first network device; and/or the CBR threshold is pre-configured or agreed upon by the protocol, or the CBR threshold is configured by the first network device; and/or the priority threshold is pre-configured or agreed upon by the protocol, or the priority threshold is configured by the first network device; and/or the QoS threshold is pre-configured or agreed upon by the protocol, or the QoS threshold is configured by the first network device.

In some implementations, after the first terminal device determines to deactivate the first resource allocation mode corresponding to the target service, the first terminal device sends fourth indication information to the second terminal device, where the fourth indication information is used to instruct the second terminal device to deactivate the first resource allocation mode corresponding to the target service.

In some embodiments, the fourth indication information may be sent by one of:

PC5-RRC signaling, MAC CE signaling, SCI signaling.

In some embodiments, the fourth indication information includes first cause information, where the first cause information is used to indicate a cause of deactivating the first resource allocation pattern corresponding to the target service.

For example, if the second condition includes that the first network device reconfigures the resource allocation pattern for the first terminal device in a case that the first terminal device is within coverage of the first network device and the first terminal device is in an RRC connected state, the first cause information includes that the first network device reconfigures the resource allocation pattern for the first terminal device.

For another example, if the second condition includes that the unicast link corresponding to the target service generates RLF, the first cause information includes that the unicast link corresponding to the target service generates RLF.

For another example, if the second condition includes that the RSRP of the unicast link corresponding to the target service is lower than the sidelink RSRP threshold, the first cause information includes that the RSRP of the unicast link corresponding to the target service is lower than the sidelink RSRP threshold.

For another example, if the second condition includes that the CBR of the transmission resource pool corresponding to the target service is greater than the CBR threshold, the first cause information includes that the CBR of the transmission resource pool corresponding to the target service is greater than the CBR threshold.

For another example, if the second condition includes that the first terminal device has a service to be transmitted with a priority higher than a priority threshold, the first cause information includes that the first terminal device has a service to be transmitted with a priority higher than a priority threshold.

For another example, if the second condition includes that the first terminal device has a service to be transmitted with QoS higher than a QoS threshold, the first cause information includes that the first terminal device has a service to be transmitted with QoS higher than a QoS threshold.

In some embodiments, the first terminal device switches the resource allocation mode corresponding to the target service from the first resource allocation mode to the second resource allocation mode. For example, the second resource allocation pattern is pattern a or pattern B described above.

In some embodiments, the first terminal device switches the resource allocation mode corresponding to the target service from the first resource allocation mode to the second resource allocation mode according to the priority information of the resource allocation mode; wherein the second resource allocation pattern has a lower priority than the first resource allocation pattern.

In some embodiments, the resource allocation pattern priority information is pre-configured or agreed upon by the protocol, or the resource allocation pattern priority information is configured by the first network device.

Therefore, in the embodiment of the present application, the first terminal device determines that the target service corresponds to the first resource allocation mode, so that the second terminal device may schedule the first terminal device through unicast connection, and the first terminal device may send the target service to the second terminal device based on the resources scheduled by the second terminal device.

s310, the second terminal equipment determines that the second terminal equipment has the capability of activating a first resource allocation mode corresponding to the target service; wherein the first resource allocation mode is a mode in which the second terminal device schedules the first terminal device through unicast connection.

In some embodiments, in case the first terminal device determines that the target service corresponds to the first resource allocation pattern, the second terminal device determines that it has the capability to activate the first resource allocation pattern corresponding to the target service.

In some embodiments, the second terminal device receives third indication information sent by the first terminal device, where the third indication information is used to instruct the first terminal device to determine that the target service corresponds to the first resource allocation mode.

In some embodiments, the third indication information may be sent by one of:

PC5-RRC signaling, MAC CE signaling, SCI signaling.

In some embodiments, the second terminal device determines, according to a third condition, that the second terminal device has the capability of activating the first resource allocation mode corresponding to the target service; wherein the third condition includes at least one of:

The CBR of the resource pool configured for the target service is less than a CBR threshold;

the RSRP of the unicast link corresponding to the target service is higher than the side-row RSRP threshold;

the unicast scheduling connection number is not more than the maximum capability value of the second terminal equipment;

the unicast scheduling connection number is not more than a connection number threshold value;

the second terminal equipment does not have the service to be transmitted with the priority higher than the priority threshold;

the second terminal device does not have traffic to be transmitted with QoS above the QoS threshold.

For example, the second terminal device performs CBR measurement on a resource pool configured for the target service (i.e., a resource pool corresponding to the first resource allocation mode), determines a congestion degree of the resource pool, and if the CBR measurement value of the resource pool is greater than a CBR threshold, or the CBR measurement value of the resource pool is equal to the CBR threshold, the second terminal device cannot enter the first resource allocation mode to schedule the first terminal device; if the CBR measurement of the resource pool is less than the CBR threshold, the second terminal device has the capability to enter the first resource allocation mode to schedule the first terminal device.

For another example, the second terminal device performs RSRP measurement on the unicast link corresponding to the target service, determines the link quality, and if the RSRP of the unicast link corresponding to the target service is not higher than a sidelink RSRP threshold, the second terminal device cannot enter the first resource allocation mode to schedule the first terminal device; if the RSRP of the unicast link corresponding to the target service is higher than the sidelink RSRP threshold, the second terminal device has the capability of entering the first resource allocation mode to schedule the first terminal device.

For another example, the second terminal device determines whether the current unicast scheduling connection number is greater than the maximum capability value of the second terminal device, or the second terminal device determines whether the current unicast scheduling connection number is greater than a connection number threshold, and if so, the second terminal device cannot enter the first resource allocation mode to schedule the first terminal device; if not, the second terminal device has the capability to enter the first resource allocation mode to schedule the first terminal device.

For another example, the second terminal device determines whether there is a service to be transmitted with a priority higher than a priority threshold, or the second terminal device determines whether there is a service to be transmitted with a QoS higher than a QoS threshold, if there is such a service to be transmitted, the second terminal device preferentially transmits the service of itself, and temporarily cannot enter the first resource allocation mode to schedule the first terminal device; if no such traffic to be transmitted exists, the second terminal device has the capability to enter the first resource allocation mode to schedule the first terminal device.

In some embodiments, the second terminal device receives and sends first indication information to the first terminal device, where the first indication information is used to indicate that the second terminal device has a capability of activating the first resource allocation mode corresponding to the target service.

In some embodiments, the first indication information may be sent by one of:

After receiving the scheduling request, the base station indicates to the second terminal equipment whether to agree to schedule the first terminal equipment by using the first resource allocation mode. If the base station indicates agreement, optionally, the base station may simultaneously allocate the resource pool corresponding to the first resource allocation mode to the second terminal device. And after receiving the consent indication of the base station and optionally the resource pool configuration, the second terminal equipment sends scheduling request feedback to the first terminal equipment.

Specifically, for example, a first terminal device is in a coverage of a first network device, the first terminal device is in an RRC connection state, a second terminal device is in a coverage of a second network device, and the second terminal device is in an RRC connection state, as shown in fig. 7, the first terminal device sends a destination identifier 1 (destination ID 1) to the first network device through direct link terminal auxiliary information (SidelinkUEInformation), where the destination identifier 1 indicates a target service and the second terminal device; after the first network device receives the destination identifier 1, the first network device may configure the first terminal device with the first resource allocation mode corresponding to the target service, as shown in fig. 7, and the first network device sends second indication information to the first terminal device through an RRC reconfiguration message (rrcrecon configuration), where the second indication information is used to indicate that the destination identifier 1 corresponds to the first resource allocation mode, and the first terminal device sends a resource allocation mode switching request to the second terminal device. As shown in fig. 7, the second terminal device sends destination ID2 (destination ID 2) to the first network device through link terminal auxiliary information (sendlink ue information), where the destination ID2 indicates a scheduling request for the target service and the first terminal device; after the second network device receives the destination identifier 2, the second network device may instruct to grant the scheduling request (ACK) of the second terminal device for the target service/the resource pool configuration corresponding to the target service, as shown in fig. 7, and the second network device sends fifth instruction information to the second terminal device through an RRC reconfiguration message (rrcrecon configuration), where the fifth instruction information is used to instruct to grant the scheduling request of the second terminal device for the target service, and the fifth instruction information includes the resource pool configuration corresponding to the target service.
