It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various information, these information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. The word "if" as used herein may be interpreted as "at … …" or "at … …" or "responsive to a determination", depending on the context.

First, the terms involved in the embodiments of the present application will be briefly described:

1. LTE (Long Term Evolution ) D2D (Device-to-Device, device-to-Device communication)/V2X:

internet of vehicles (Vehicle to everything, V2X): is a key technology of an intelligent transportation system in the future, and mainly researches a vehicle data transmission scheme based on a 3GPP communication protocol. V2X communications include vehicle-to-vehicle (Vehicle to Vehicle, V2V) communications, vehicle-to-road side infrastructure (Vehicle to Infrastructure, V2I) communications, and vehicle-to-pedestrian (Vehicle to People, V2P) communications. V2X applications will improve driving safety, reduce congestion and vehicle energy consumption, increase traffic efficiency, etc.

Side Link (SL) transmission: is a device-to-device communication mode, and has higher spectral efficiency and lower transmission delay. Device-to-device communication is a side-link transmission technology, and unlike traditional cellular systems in which communication data is received or transmitted through network devices, the internet of vehicles system adopts a terminal-to-terminal direct communication mode, so that the system has higher spectral efficiency and lower transmission delay. Two transmission modes for side-link transmission are defined in 3 GPP: mode 1 and mode 2.

Mode 1 as shown in (1) in fig. 1: the network device 110 configures transmission resources for the terminal 120, and the terminal 120 performs data transmission of the side uplink on the configured transmission resources.

Mode 2 as shown in (2) in fig. 1: the network device 110 allocates a resource pool for the terminal 120, and the terminal 120 selects one or more transmission resources from the resource pool for data transmission of the side link. The terminal 120 may select transmission resources in the resource pool by sensing (or translating to "listening") or may select transmission resources in the resource pool by random selection, for example.

In mode 2, the terminal selects time-frequency resources from a resource pool (candidate resources) configured or preconfigured by the network equipment by means of resource perception or random selection for sending the testability information. Thus, a more accurate description of mode 2 resource allocation should be a resource selection.

In SI phase of NR (New Radio) V2X, 4 resource allocation schemes of mode 2 have been proposed, namely mode 2a, mode 2b, mode 2c and mode 2d.

Mode 2a refers to that the terminal selects resources which are not reserved by other terminals or reserved by other terminals but have lower receiving power in the resource pool by the methods of decoding side uplink control information, measuring side uplink receiving power and the like, so that the collision probability of the resources is reduced, and the communication reliability is improved. Mode 2a inherits the main design of the resource selection mechanism in LTE V2X mode 4 as a whole, and performs resource selection based on operations such as resource reservation, resource awareness, and resource exclusion.

The mode 2b is a mode of resource selection through cooperation between terminals, namely, the terminals send auxiliary information to help other terminals complete resource selection. The auxiliary information may be a result of resource sensing by the terminal, or a resource recommended to be used by other terminals. For example, terminal C sends auxiliary information to terminals a and B, which select resources in the resource pool using the auxiliary information and the perceived result of their own resource perception.

Mode 2c refers to that the network device configures or pre-configures the resource pattern (pattern) of the terminal, and the terminal utilizes the resources in the resource pattern to send the initial transmission and retransmission, so as to achieve the effect of reducing the sending delay. The network device may configure one or more resource patterns, and when the configured resource patterns are plural, the terminal selects one of the resource patterns using the resource awareness or the geographical location information.

In mode 2d, the terminal directly schedules time-frequency resources for other terminals.

In the embodiment of the present application, the second terminal (the scheduled terminal) operates in the mode 2d, and the first terminal (the scheduled terminal) may operate in the mode 1 or in the mode 2.

In 3GPP, D2D is studied in different stages.

ProSe (Proximity based Service, proximity-based service): device-to-device communication in Rel-12/13 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, the UE (User Equipment) can discontinuously transmit/receive data on the side downlink, so as to achieve the effect of power saving.

Internet of vehicles (V2X): in Rel-14/15, a car networking system is researched aiming at a scene of car-car communication, and is mainly oriented to traffic of car-car and car-man communication moving 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): in Rel-14, this scenario is studied for a scenario where a wearable device accesses a network through a handset, which is mainly oriented to a scenario of low movement speed and low power access. In FeD2D, the 3GPP concludes that the network device can configure DRX (Discontinuous Reception ) parameters of remote terminals through one relay terminal in the pre-research stage, but the specific details of how DRX configuration is performed are not concluded since the subject does not go further into the standardization stage.

2、NR V2X：

NR V2X is not limited to broadcast scenes on the basis of LTE V2X, but extends further to unicast and multicast scenes where V2X applications are studied.

Similar to LTE V2X, NR V2X will also define two resource grant modes, mode 1 and mode 2, described above; furthermore, the terminal may be in a mixed mode, i.e. the resource acquisition may be performed using mode 1, and the resource acquisition may be performed using mode 2. The resource acquisition is indicated by means of a side-link grant, i.e. the side-link grant indicates the time-frequency positions of the corresponding PSCCH (Physical Sidelink Control Channel, physical side-link control channel) and PSSCH (Physical Sidelink Shared Channel, physical side-link shared channel) 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 HARQ (Hybrid Automatic Repeat reQuest ) 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.

Fig. 2 is a block diagram of a communication system supporting side-link transmission according to an exemplary embodiment of the present application. The communication system may be a schematic diagram of a Non-roaming 5G system architecture (Non-roaming 5G system architecture) that may be applied to internet of vehicles (Vehicle to everything, V2X) traffic using D2D (Device to Device) technology.

The system architecture includes a Data Network (DN) in which V2X application servers (Application Server) required for V2X services are located.

The system architecture further includes: a radio access network (New Generation-Radio Access Network, NG-RAN) has 4 terminals (i.e., terminal 1 to terminal 4) as exemplarily shown. Optionally, each terminal is provided with a V2X Application (Application) or an Application supporting SL transport. The radio access network has one or more access network devices, such as base stations (gnbs), disposed therein.

In the system framework, a data network is connected with a user plane function in a 5G core network through an N6 Reference Point, and a V2X application server is connected with a V2X application in a terminal through a V1 Reference Point; the wireless access network is connected with an AMF function and a UPF function in the 5G core network, and is respectively connected with the terminal 1 and the terminal 5 through Uu reference points; and the plurality of terminals perform side-link transmission through a PC5 reference point, and the plurality of V2X applications are connected through a V5 reference point. The above-mentioned reference points may also be referred to as "interfaces".

The "5G NR system" in the embodiments of the present disclosure may also be referred to as a 5G system or an NR system, but a person skilled in the art may understand the meaning thereof. The technical scheme described in the embodiment of the disclosure can be applied to a 5G NR system and also can be applied to a subsequent evolution system of the 5G NR system. The technical solution described in the embodiments of the present disclosure may be applicable to V2x applications, and may also be applicable to other applications using side-link transmission, such as public security (public security) and business applications.

Referring to fig. 3, a flowchart of a method for requesting transmission resources according to an embodiment of the present application is shown, and the method may be applied to the system architecture shown in fig. 2. The method comprises the following steps.

In step 210, the second terminal sends a resource request signaling to the first terminal, where the resource request signaling is used to request the first terminal to schedule transmission resources for the second terminal.

For example, when the second terminal needs to transmit data (sidelink data) to the first terminal through sidelink transmission, a resource request signaling is transmitted to the first terminal, requesting the first terminal to schedule transmission resources for the second terminal to transmit the data. The second terminal, after receiving the transmission resource (first transmission resource) scheduled by the first terminal for it, transmits data of the side uplink transmission to the first terminal on the first transmission resource.

The second terminal is a transmitting terminal of the side line data, and the first terminal is a receiving terminal of the side line data. The first terminal schedules transmission resources for the second terminal, the second terminal is a scheduled terminal, and the first terminal is a scheduling terminal.

The resource request signaling is used to request scheduling of transmission resources for transmission of side row data for the second terminal. The resource request signaling includes at least one of an identifier of the second terminal, a packet size of the sidestream data, a data priority of the sidestream data, and a service identifier.

Step 220, the first terminal receives the resource request signaling sent by the second terminal.

The first terminal receives the resource request signaling sent by the second terminal, and schedules a first transmission resource for sending the sidestream data for the second terminal according to the resource request signaling.

In step 230, the first terminal sends side uplink scheduling information to the second terminal, the side uplink scheduling information being used to indicate the first transmission resources scheduled for the second terminal.

For example, after determining the first transmission resource scheduled for the second terminal, the first terminal generates side uplink scheduling information in which the first transmission resource scheduled for the second terminal is indicated to the second terminal.

The first transmission resource is used for transmitting sidelink data of a sidelink transmission.

Illustratively, the sidelink scheduling information is carried on a PSCCH (Physical Sidelink Control Channel ) or a PSSCH (Physical Sidelink Shared Channel, physical sidelink shared channel).

In step 240, the second terminal receives the side uplink scheduling information sent by the first terminal.

The second terminal receives the side uplink scheduling information and transmits side uplink data to the first terminal on the first transmission resource indicated by the side uplink scheduling information.

In summary, in the method provided in this embodiment, the second terminal in the side uplink transmission sends the resource request signaling to the first terminal, so as to request the first terminal to schedule transmission resources for the second terminal, and the first terminal schedules transmission resources for the second terminal, and sends the scheduled transmission resources to the second terminal, so that the second terminal performs the side uplink transmission on the transmission resources scheduled by the first terminal. And when the second terminal is positioned outside the coverage area of the network equipment, or the perceived result of the second terminal is inaccurate and unavailable, or the network equipment is congested in a resource pool configured for the second terminal, the second terminal can complete the selection of transmission resources through the first terminal, so that the second terminal can complete the side uplink transmission by using the proper transmission resources.

The method provided by the embodiment can solve the problem that when the second terminal is out of coverage of the network equipment and the sensing result is unavailable, the second terminal can acquire reliable transmission resources through the opposite terminal (the first terminal) in the mode 2 d. Meanwhile, when the second terminal is in the mode 2d, the reliability of the transmission resource can be ensured even if the second terminal does not sense. Therefore, the power consumption of the second terminal can be effectively reduced.

Illustratively, the second terminal needs to acquire transmission resources for transmitting the resource request signaling before transmitting the resource request signaling.

Referring to fig. 4, a flowchart of a method for requesting transmission resources according to an embodiment of the present application is shown, and the method may be applied to the system architecture shown in fig. 2. Based on the exemplary embodiment shown in fig. 3, step 210 is preceded by step 205, step 210 is further comprised of step 211, and step 220 is further comprised of step 221.

In step 205, the second terminal acquires a second transmission resource for transmitting the resource request signaling.

The second transmission resource is used for transmitting resource request signaling. The second transmission resource may be determined by the second terminal from the resource pool, may be configured by the network device for the second terminal, or may be scheduled by the first terminal for the second terminal, for example.

In the embodiment of the present application, at least the following four manners of acquiring the second transmission resource are provided:

and 1.1, the second terminal determines a second transmission resource through perception.

1.2, the second terminal requests the first terminal to schedule the second transmission resource for the second terminal.

1.3, the second terminal requests the network device to configure the second transmission resource for the network device.

1.4, the second terminal randomly selects a second transmission resource from a signaling transmission resource pool preconfigured by the first terminal.

Step 211, the second terminal sends a resource request signaling to the first terminal on the second transmission resource.

In step 221, the first terminal receives the resource request signaling sent by the second terminal on the second transmission resource.

In summary, in the method provided in this embodiment, the second terminal may obtain the second transmission resource for transmitting the resource request signaling in multiple manners, and in different application scenarios, the second terminal may obtain the second transmission resource in different acquisition manners, so as to send the resource request signaling to the first terminal on the second transmission resource.

Referring to fig. 5, a flowchart of a method for requesting transmission resources according to an embodiment of the present application is shown, and the method may be applied to the system architecture shown in fig. 2. Based on the exemplary embodiment shown in fig. 4, step 205 includes step 2051.

Step 2051, the second terminal perceives transmission resources to the candidate resources to obtain a first perceiving result; a second transmission resource is determined based on the first perceived result.

And the second terminal adopts a mode 2 to sense the candidate resources configured by the network equipment, and determines a second transmission resource from the candidate resources according to the sensing result. The candidate resource is illustratively a transmission resource that the network device pre-configures for the second terminal.

The second terminal performs transmission resource sensing on the candidate resources based on the priority of the resource request signaling to obtain a first sensing result. The priority of the resource request signaling can be configured by the network device, or can be determined according to the priority of the service attribute.

That is, the network device may further configure the priority of the resource request signaling for the second terminal, so that the second terminal performs resource awareness according to the priority of the resource request signaling, so as to select the second transmission resource. The second terminal receives the priority of the resource request signaling configured by the network equipment for the second terminal; and sensing transmission resources of the candidate resources based on the priority, and obtaining a first sensing result.

The second terminal may further determine a priority of the resource request signaling according to the priority of the service attribute, and further perform resource sensing according to the priority of the resource request signaling, so as to select the second transmission resource. The second terminal configures the priority of the resource request signaling according to the priority of the service attribute; and sensing transmission resources of the candidate resources based on the priority, and obtaining a first sensing result. Optionally, the second terminal configures the priority of the resource request signaling according to the priority of the service attribute of the second terminal. That is, the priority of the resource request signaling is determined according to the priority of the service attribute of the second terminal.

The second terminal may remove the unavailable transmission resources from the candidate resources based on the first sensing result, and randomly select the transmission resources from the remaining available transmission resources as the second transmission resources.

In summary, according to the method provided in this embodiment, the second terminal may select the second transmission resource for transmitting the resource request signaling from the candidate resources preconfigured by the network device through sensing, and further send the resource request signaling to the first terminal on the second transmission resource.

Based on the exemplary embodiment shown in fig. 4, step 205 includes steps 2052, 2053.

In step 2052, the second terminal sends a first request to the first terminal, where the first request is used to request to acquire a transmission resource for sending a resource request signaling.

The first terminal receives a first request sent by the second terminal, and schedules a second transmission resource for sending a resource request signaling for the second terminal according to the first request.

Illustratively, the first request includes a scheduling request (Scheduling Request, SR). Illustratively, the Scheduling Request (SR) may also be referred to as a sidelink scheduling request.

The network device configures SR resources on the side uplink transmission for the second terminal. The second terminal selects a transmission resource from SR resources configured by the network device and transmits a first request (e.g., a first SR request) to the first terminal. The first request is for requesting acquisition of transmission resources for transmitting resource request signaling from the first terminal.

Specifically, after the first terminal establishes a PC5-RRC (Radio Resource Control ) connection with the second terminal, the first terminal configures a resource pool of the used mode 2 to the second terminal through the PC5-RRC, and at the same time, the first terminal indicates SR resources used by the second terminal in the resource pool to the second terminal.

In step 2052, the first terminal schedules a second transmission resource for transmitting the resource request signaling to the second terminal.

The second terminal receives a second transmission resource which is scheduled by the first terminal and used for sending the resource request signaling.

In summary, according to the method provided in this embodiment, the second terminal may send the first request to the first terminal, so that the first terminal schedules, to the second terminal, the second transmission resource for transmitting the resource request signaling according to the first request, and further sends the resource request signaling to the first terminal on the second transmission resource.

In step 2054, the second terminal sends a second request to the network device, where the second request is for requesting to acquire transmission resources for sending the resource request signaling.

The network equipment receives a first request sent by the second terminal, and configures second transmission resources for sending resource request signaling for the second terminal according to the first request.

Illustratively, the second request includes a Side Link-buffer status report (SL-BSR) or a scheduling request (Scheduling Request, SR). Illustratively, the Scheduling Request (SR) may also be referred to as a sidelink scheduling request.

The second terminal sends a second request to the network device in a mode 1, and the network device is requested to configure transmission resources for sending the resource request signaling for the second terminal.

Specifically, the second terminal autonomously switches the transmission mode to mode 1, and the second terminal transmits the SL-BSR or the SR to request transmission resources for transmitting the resource request signaling to the network device.

In step 2055, the network device configures a second transmission resource for transmitting the resource request signaling to the second terminal.

The second terminal receives a second transmission resource configured by the network device and used for sending the resource request signaling.

In summary, in the method provided in this embodiment, the second terminal may send the second request to the network device, so that the network device configures, for the second terminal, a second transmission resource for transmitting the resource request signaling according to the second request, and further sends the resource request signaling to the first terminal on the second transmission resource.

Referring to fig. 8, a flowchart of a method for requesting transmission resources according to an embodiment of the present application is shown, and the method may be applied to the system architecture shown in fig. 2. Based on the exemplary embodiment shown in fig. 4, step 205 includes steps 2056, 2057.

In step 2056, the first terminal configures a signaling transmission resource pool to the second terminal, where transmission resources in the signaling transmission resource pool are used to transmit the resource request signaling.

The first terminal configures a signaling sending resource pool for the second terminal before starting to schedule the second terminal, and when the second terminal needs to send the resource request signaling, the signaling sending resource pool automatically selects transmission resources to send the resource request signaling.

In step 2057, the second terminal determines a second transmission resource from the signaling transmission resource pool for transmitting the resource request signaling.

Illustratively, the second terminal randomly selects a second transmission resource for transmitting the resource request signaling from the signaling transmission resource pool.

The second terminal may also select a second transmission resource for transmitting the resource request signaling from the signaling transmission resource pool according to the sensing result of the signaling transmission resource pool.

In summary, in the method provided in this embodiment, the first terminal may configure, in advance, a signaling sending resource pool for sending the resource request signaling for the second terminal, and the second terminal may randomly select, from the signaling sending resource pool, a second transmission resource for transmitting the resource request signaling, and further send the resource request signaling to the first terminal on the second transmission resource.

For example, the first terminal may schedule transmission resources for transmitting sidestream data for the second terminal in a variety of ways.
