Description

Setting method, terminal equipment and network equipment

Technical Field

The present application relates to the field of communications, and more particularly, to a setting method, a terminal device, and a network device.

Background

Device-to-Device communication is a side-link (SL) transmission technology based on a D2D technology, which has higher spectral efficiency and lower transmission delay, unlike the conventional cellular system in which communication data is received or transmitted through 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 (3GPP,3rd Generation Partnership Project): a first mode and a second mode. In the second mode, the terminal may select one resource from the preconfigured or network configured resource pool to perform side transmission of data. After the terminals select the transmission resources, if data is directly transmitted on the resources, there is a possibility that two terminals select the same transmission resources and resource collision occurs. In order to solve this problem, a resource preemption (pre-solution) and re-evaluation (re-evaluation) mechanism is introduced into a New air-vehicle to other devices (NR-V2X, new Radio-Vehicle to Everything), so that a terminal can determine whether there is a resource conflict with other terminals before using the selected resource, if there is no conflict, the selected transmission resource can be continuously used, and if there is a resource conflict, avoidance and resource reselection are required according to corresponding mechanisms to avoid the resource conflict.

In order to reduce the power consumption, some terminals have no reception capability of sidestream data, i.e. have no interception capability. When a resource pool supports acquisition of transmission resources in a random selection mode and acquisition of transmission resources in a interception mode, a terminal without interception capability randomly selects resources, and then re-evaluation or pre-transmission detection is not carried out, and the selected resources are directly used for side transmission; after the terminal with interception capability selects the transmission resource, before using the resource to perform sidestream transmission, re-evaluation or pre-transmission detection is needed to determine whether resource conflict occurs with other terminals. For example, for pre-transmission detection, when a terminal with interception capability detects that a resource conflict occurs, the priority of the terminal is lower than that of the terminal with conflict, and the reference signal received power (RSRP, reference Signal Received Power) of other terminals is detected to be higher than a threshold, the terminal reselects the resource at the moment so as to avoid the conflict with other terminals; if the terminal has a higher priority than the terminal with conflict, the terminal will not perform resource reselection, but the terminal with conflict is expected to perform resource reselection, i.e. the terminal with high priority can use the conflict resource preferentially. However, if other terminals with collision are terminals without interception capability, pre-transmission detection is not performed, and resource reselection is not performed, so that the result is that the low-priority terminal can avoid resource collision with the terminals without interception capability, but the high-priority terminal cannot avoid resource collision with the terminals without interception capability, that is, the terminals without interception capability collide with the high-priority data transmission resources with interception capability, thereby affecting the performance of the high-priority data transmission.

In the side line communication, according to the network coverage condition of the terminal for communication, the network coverage inside line communication, the partial network coverage side line communication and the network coverage outside line communication can be divided as shown in fig. 1A, 1B and 1C, respectively.

As shown in fig. 1A, in network coverage inside-line communication, all terminals performing side-line communication are within the coverage of the same base station, and all the terminals may perform side-line communication based on the same side-line configuration by receiving configuration signaling of the base station.

As shown in fig. 1B, in the case of partial network coverage sidestream communication, a part of terminals performing sidestream communication are located within the coverage area of the base station, and this part of terminal terminals can receive the configuration signaling of the base station and perform sidestream communication according to the configuration of the base station. In this case, the terminal outside the network coverage area determines the sidestream configuration according to the pre-configuration information and the information carried in the physical sidestream broadcast channel (PSBCH, physical Sidelink Broadcast Channel) sent by the terminal located in the network coverage area, so as to perform sidestream communication.

As shown in fig. 1C, for network coverage outside line communication, all terminals performing outside line communication are located outside the network coverage, and all terminals determine side line configuration according to the pre-configuration information to perform side line communication.

Device-to-device communication is a D2D based side-link transmission technique, and has higher spectral efficiency and lower transmission delay, unlike conventional cellular systems in which communication data is received or transmitted by a base station. The internet of vehicles system adopts a terminal-to-terminal direct communication mode, and two transmission modes are defined in 3 GPP: a first mode and a second mode.

First mode: 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. 1A, the terminal is located in the coverage area of the network, and the network allocates transmission resources for side transmission to the terminal.

Second mode: and the terminal selects one resource from the resource pool to transmit data. As shown in fig. 1C, the terminal is located outside the coverage area of the cell, and the terminal autonomously selects transmission resources in a preconfigured resource pool to perform side transmission; or in fig. 1A, the terminal autonomously selects transmission resources from a resource pool configured by the network to perform side transmission.

In NR-V2X, automatic driving needs to be supported, and thus, higher demands are placed on data interaction between vehicles, such as higher throughput, lower latency, higher reliability, larger coverage, more flexible resource allocation, etc.

When the terminal of NR-V2X operates in the second mode (i.e., mode 2 in NR-V2X), the terminal performs resource selection according to interception, specifically, when a new data packet arrives in time slot n, resource selection is required, and the terminal performs resource selection in a resource selection window according to the interception result of a period of time. Fig. 2 is a schematic diagram of a manner in which a terminal performs resource selection within a selection window. In the example shown in fig. 2, the resource listening window (abbreviated listening window) determined by the terminal is [ n-1000, n-1 ], and the resource selection window (abbreviated selection window) is [ n+1, n+100].

The brief process of the terminal for selecting the resources in the selection window is as follows:

1. the terminal will select all available resources within the window as one set a,

2. if the terminal does not have a interception result in some subframes in the interception window, the resources of the subframes corresponding to the subframes in the selection window are eliminated;

3. if a terminal detects a physical sidelink control channel (PSCCH, physical Sidelink Control Channel) in a listening window, measuring the RSRP of the PSCCH or the RSRP of a physical sidelink shared channel (PSSCH, physical Sidelink Shared Channel) scheduled by the PSCCH, and if the measured RSRP is above an RSRP threshold and there is a resource conflict between its reserved transmission resources determined according to reservation information in the control information and data to be transmitted by the user, the user excludes the resources in set a. The selection of the RSRP threshold is determined by the priority information carried in the detected PSCCH and the priority of the data to be transmitted by the terminal.

4. If the number of the remaining resources in the set a is less than the total number of resources by X%, the terminal may raise the threshold of RSRP by 3dB, and repeat the above steps until the number of the remaining resources in the set a is greater than the total number of resources by X%. Where X is a high level configuration parameter.

5. And the terminal reports the set A to a high-rise.

And the higher layer randomly selects N transmission resources from the available resource set reported by the physical layer for side transmission.

After the terminal selects the transmission resource, as there is a possibility that two terminals will collide with each other due to the selection of the same transmission resource, in order to solve this problem, pre-transmission and re-evaluation mechanisms are introduced into NR-V2X, so that before using the selected resource, the terminal can determine whether there is a resource collision with other terminals, if there is no collision, the terminal can continue to use the selected transmission resource, if there is a resource collision, avoidance and resource reselection are required according to the corresponding mechanisms to avoid the resource collision.

In the re-evaluation mechanism, the terminal still continuously listens for sidestream control information after completing resource selection, and re-evaluates the selected but not indicated resources at least once. FIG. 3 is a schematic diagram of a re-evaluation mechanism. As shown in fig. 3, the resource w, x, y, z, v is a time-frequency resource that the UE has selected at time n, and the resource x is located in the slot m. Resources y and z for which the UE is about to send sidelink control information for the first time at resource x (resource x has been indicated previously by sidelink control information in resource w). The UE is at least in time slot m-T ₃ And performing primary resource interception, namely determining a resource selection window and an interception window, and performing resource elimination on resources in the resource selection window to obtain a candidate resource set. If resources y or z are not in the candidate resource set, the UE reselects time-frequency resources among resources y and z that are not in the candidate resource set, and may also reselect any of the resources that have been selected but not indicated by the transmission-side row control information, e.g., any of resources y, z, and v. The above m-T ₃ Depending on the processing capabilities of the terminal.

In NR-V2X, the conclusions about the pre-transmission mechanism are all described in terms of preempted UEs. After completing the resource selection, the UE still continues to listen to the sidestream control information, and triggers a resource reselection if the time-frequency resources that have been selected and indicated by the sending sidestream control information meet the following three conditions:

1. the resources reserved in the detected sidestream control information overlap with the resources selected and indicated by the UE, including all overlap and partial overlap.

The RSRP of PSCCH corresponding to the lateral control information detected by the UE or the RSRP of PSSCH scheduled by the PSCCH is larger than the SL RSRP threshold.

3. The priority carried in the detected side-uplink control information (SCI, sidelink Control Information) is higher than the priority of the data to be transmitted by the UE.

FIG. 4 is a schematic diagram of the pre-emission mechanism. As shown in fig. 4, the resource w, x, y, z, v is a time-frequency resource that the UE has selected, and the resource x is located in the slot m. For resources x and y indicated by the sidestream control information that the UE is about to send in slot m and that has been indicated by the sidestream control information that the UE sent before. The UE is at least in time slot m-T ₃ And performing primary resource interception to determine a candidate resource set. If the resource x or y is not in the candidate resource set (meeting the conditions 1 and 2), further judging whether the resource x or y is not in the candidate resource set (meeting the condition 3) due to the indication of carrying the side uplink control information with high priority, if so, the UE performs resource reselection, and reselects the time-frequency resource meeting the 3 conditions in the x and y.

The terminal without interception capability randomly selects sidestream resources, and re-evaluation or pre-emission detection is not carried out; after selecting the transmission resource, the terminal with interception capability needs to perform re-evaluation or pre-transmission detection before using the resource for sidestream transmission to judge whether resource conflict occurs with other terminals. And when a conflict occurs, if the priority of the terminal with interception capability is higher than that of the terminal with conflict, the terminal does not perform resource reselection, but the terminal with conflict is expected to perform resource reselection, so that the terminal without interception capability only interferes with the side transmission of the terminal with interception capability with high priority.

In view of the above, the present embodiment proposes a setting method, and fig. 5 is a schematic flowchart of a setting method 500 according to the present embodiment, which may be alternatively applied to the above-described terminal device without interception capability. The method includes at least part of the following:

s510: when the first terminal device transmits the sidestream data, the priority in the SCI for scheduling the sidestream data is set as the first priority.

The first terminal device may comprise a terminal device without interception capability.

In the prior art, when a terminal sends side line data, the priority of the side line data is borne in an SCI; in this embodiment, the first priority carried in the SCI may be different from the priority corresponding to the sidestream data sent by the first terminal device.

In one embodiment, the first priority may be set to a highest priority.

Optionally, the highest priority is the highest priority in priority levels allowed by the resource pool for transmitting the sidestream data by the first terminal device, or the highest priority is the highest priority in all priorities corresponding to the sidestream data.

Example 1:

in this embodiment, when a terminal having no interception capability transmits side line data, the first priority in SCI which schedules the side line data is set to the highest priority.

When the terminal with interception capability performs pre-transmission detection, the terminal performs resource reselection under the condition that the following conditions are satisfied:

1. resources reserved in sidestream control information of other terminals (RX UEs) that are listened to by the listening terminal (TX UE) overlap with resources that have been selected and indicated by the TX UE, including all overlap and partial overlap.

RSRP of PSCCH corresponding to SCI of RX UE and detected by tx UE or RSRP of PSCCH scheduled PSSCH is greater than SL RSRP threshold.

The first priority (p_rx) carried in the sidestream control information of the RX UE detected by the TX UE is higher than the priority (p_tx) of the data to be sent by the TX UE, i.e. p_rx < p_tx, where p_rx and p_tx represent values corresponding to the priority levels, and the higher the value, the lower the priority level. For example, the priorities corresponding to the sidestream data include 8 levels, i.e., [0,7], where a priority level value of 0 indicates the highest priority and a priority level value of 7 indicates the lowest priority.

For terminals without interception capability, the transmission resources are acquired in a random selection mode, and when the transmission resources are used for lateral transmission, the first priority in the SCI is set to be the highest priority, so that the priority level of other terminals is lower than or equal to the priority level of the terminal when pre-transmission detection is carried out, and one of the conditions for triggering the terminal to reselect resources can be met.

It can be seen that the first priority in SCI of the terminal without interception capability is set to be the highest level, so that the priority of the other terminals with interception capability is lower than (or equal to) the priority of the terminal without interception capability, and in the pre-transmission detection mechanism, the terminal with interception capability can more easily meet the condition of resource preemption, trigger resource reselection, and avoid resource conflict with the terminal without interception capability.

When a terminal with interception capability performs resource selection or re-evaluation detection, if the terminal detects PSCCH in an interception window, the RSRP of the PSCCH or the RSRP of PSSCH scheduled by the PSCCH is measured, and if the measured RSRP is higher than an RSRP threshold and the reserved transmission resource determined according to reservation information in SCI has resource conflict with data to be sent by the terminal, the terminal with interception capability excludes the resource from an available resource set. The selection of the RSRP threshold is determined by the priority information carried in the detected PSCCH and the priority of the data to be transmitted by the terminal, and the higher the priority is, the higher the corresponding RSRP threshold is.

It can be seen that, setting the first priority in SCI of the terminal without interception capability to the highest level, so that the determined RSRP threshold is the highest, after the terminal with interception capability detects the PSCCH in the interception window, the possibility that the RSRP of the PSCCH or the RSRP of the PSCCH scheduled by the PSCCH is measured to be higher than the RSRP threshold is the smallest, and the possibility that the terminal with interception capability excludes the reserved transmission resource without interception capability from the available resource set is the smallest. Therefore, no matter the priority of the terminal with interception capability, the terminal is not easy to trigger resource reselection, and resource conflict exists between the transmission of the terminal without interception capability and the terminals with interception capability of all priorities, so that the terminal without interception capability is prevented from only interfering with the side transmission of the terminal with interception capability of high priority.

In another embodiment, the first priority may be set to the lowest priority.

Optionally, the lowest priority is the lowest priority in priority levels allowed by the resource pool for transmitting the sidestream data by the first terminal device, or the highest priority is the lowest priority in all priorities corresponding to the sidestream data.

Example 2:

in this embodiment, when a terminal having no interception capability transmits side line data, the first priority in SCI that schedules the side line data is set to the lowest priority.

When a terminal having interception capability performs pre-transmission detection, the terminal performs resource reselection in the case that the above 3 conditions are satisfied, as in embodiment 1.

For terminals without interception capability, a random selection mode is adopted to acquire transmission resources, and when the transmission resources are used for lateral transmission, the first priority in SCI is set to be the lowest priority, so that the priority level of other terminals is higher than or equal to the priority level of the terminal when pre-transmission detection is carried out, and one of the conditions for triggering the terminal to reselect resources is not met.

It can be seen that the first priority in SCI of the terminal without interception capability is set to the lowest level, so that the priority of the other terminals with interception capability is higher than (or equal to) the priority of the terminal without interception capability, and in the pre-transmission detection mechanism, the terminal with interception capability does not meet the condition of resource preemption, and the resource reselection is not triggered. Therefore, no matter the priority of the terminal with interception capability, the terminal does not trigger resource reselection, and resource conflict exists between the transmission of the terminal without interception capability and the terminals with interception capability of all priorities, so that the terminal without interception capability is prevented from only interfering with the side transmission of the terminal with interception capability of high priority.

It can be seen that, setting the first priority in SCI of the terminal without interception capability to the lowest level, so that the determined RSRP threshold is the lowest, after the terminal with interception capability detects the PSCCH in the interception window, the possibility that the RSRP of the PSCCH or the RSRP of the PSCCH scheduled by the PSCCH is higher than the RSRP threshold is measured to be the greatest, and then the possibility that the terminal with interception capability excludes the reserved transmission resource without interception capability from the available resource set is the greatest.

In another embodiment, the first priority may be set to be not higher than a priority corresponding to the first parameter; alternatively, the value of the first priority may be set to be greater than or equal to the value of the priority corresponding to the first parameter.

Alternatively, the first parameter may include a resource preemption enable (sl-preemption enable) parameter. The sl-pre enable parameter is a parameter included in the resource pool configuration information, and is used to indicate whether pre-transmission detection is supported in the resource pool. Possible values for the sl-preemptionEnable parameter include { enabled, pl1, pl2, pl3, pl4, pl5, pl6, pl7, pl8}. When the parameter is configured as "enabled", the terminal that performs interception judges whether or not it is preempted by the resource and whether or not resource selection is necessary according to the 3 conditions in embodiment 1 and embodiment 2. At this time, in the manner of embodiment 1, that is, the first priority of the terminal without interception capability is configured as the highest priority, so that when pre-transmission detection is performed, the interception terminal more easily meets the condition of being preempted by the resource, and triggers resource selection; or when the resource selection or re-evaluation detection is carried out, the interception terminal cannot easily meet the condition of being preempted by the resource, and the resource selection is not triggered. Or, in the manner of embodiment 2, that is, the first priority of the terminal without interception capability is configured to be the lowest priority, so that when pre-transmission detection is performed, the interception terminal does not easily meet the condition of being preempted by the resource, and does not trigger resource selection; or when the resource selection or re-evaluation detection is carried out, the interception terminal can more easily meet the condition of being preempted by the resource, and the resource selection is triggered.

Example 3:

in this embodiment, when the terminal without interception capability sends the sidestream data, the value of the first priority in the SCI for scheduling the sidestream data is set to be greater than or equal to the priority value corresponding to the sl-preemption enable parameter.

When the sl-PreemptionEnable parameter is configured to be p_pre, i.e., corresponds to one value of pl1 to pl8, the listening terminal determines whether or not to be preempted by the resource and whether or not to need to perform resource selection, and in addition to the 3 conditions in embodiment 1 and embodiment 2, the following conditions need to be satisfied:

and 4, the priority carried in the sidestream control information of the RX UE, which is detected by the TX UE, is higher than the priority corresponding to the parameter sl-preemptionEnable, namely P_rx < P_pre.

Only when the 4 conditions are met, the terminal for resource interception is preempted by other terminals and triggers resource selection.

When the terminal without interception capability transmits the sidestream data, the first priority in the SCI is set to be greater than or equal to a level of p_pre, that is, p_rx > =p_pre, that is, the priority of sidestream data transmitted by the terminal without interception capability is low, so that the terminal performing interception is not preempted by resources, that is, whether the priority of the terminal performing interception is lower than the priority of the terminal without interception capability, is not preempted by resources, that is, resource reselection is not performed. That is, all terminals performing resource interception do not perform resource reselection even if a resource conflict exists between the terminals having no interception capability and the resources selected by the terminals having no interception capability. A resource conflict may exist between the transmission of the terminal without interception capability and the terminals with interception capability of all priorities, thereby avoiding that only the transmission of the terminal with interception capability with high priority is interfered.

It can be seen that the first priority of the terminal without interception capability is set to be not higher than the priority threshold configured by the first parameter (for example, the sl-preemption enable parameter), the terminal with interception capability is not preempted by the resource during interception, and the resource reselection is not performed, so that the terminal without interception capability may have resource conflict with the terminals with interception capability of all priority levels, and the transmission of the terminal with interception capability with high priority is avoided.

In the above embodiments 1 to 3, by setting the first priority of the terminal device having no listening capability, it is achieved that the interference situation is the same for all priority terminals having listening capability. A transmission of a terminal without interception capability may have resource conflict with all priority terminals with interception capability or no resource conflict with all priority terminals with interception capability, thereby avoiding affecting only the transmission of a terminal with interception capability of high priority.

The embodiment of the application also provides another setting method, and the RSRP threshold corresponding to the terminal equipment without interception capability during resource selection or resource reselection is determined through certain setting, so that the transmission of the terminal with interception capability with high priority is prevented from being influenced.

Fig. 6 is a schematic flow chart of a setup method 600 according to an embodiment of the present application, which may alternatively be applied to the above-described terminal device with listening capabilities. The method includes at least part of the following:

s610: when the second terminal equipment performs resource selection, resource reselection, re-evaluation detection or pre-solution detection, determining an RSRP threshold corresponding to the first terminal equipment according to the first configuration parameter; wherein the first terminal device comprises a terminal device without interception capability.

The first configuration parameter may be determined by network configuration information or pre-configuration information.

In some embodiments, the first configuration parameter may include a priority parameter.

Optionally, the determining, according to the first configuration parameter, the RSRP threshold corresponding to the first terminal device includes:

determining an RSRP threshold according to the first configuration parameter and priority information carried in SCI of the first terminal equipment; or,

determining an RSRP threshold according to the first configuration parameter and the priority information of the second terminal equipment; or,

and determining an RSRP threshold according to the first configuration parameter, the priority information carried in the SCI of the first terminal equipment and the priority information of the second terminal equipment.

In some embodiments, the first configuration parameter may include an RSRP threshold.

Two examples of the above-described first configuration parameters are respectively described below using two examples in embodiment 4.

Example 4:

when the terminal with interception capability performs resource selection, re-evaluation detection or pre-transmission detection, if the terminal without interception capability is detected, the terminal without interception capability is used with the first configuration parameter.

The first configuration parameter may be used for terminals without listening capabilities if the terminals with listening capabilities are able to detect and identify terminals without listening capabilities.

Example 4-1:

and in the process of resource exclusion, if SCI of other terminals is detected, determining an RSRP threshold according to priority information (denoted as P_rx) carried in SCI of other terminals and priority information (denoted as P_tx) of the terminals, and if RSRP of other terminals is measured to exceed the RSRP threshold and transmission resources reserved by other terminals and resources reserved by the terminals in a resource selection window overlap, eliminating the resources from the resource selection window. In the process, if other terminals are detected to be terminals without interception capability, the terminals determine an RSRP threshold according to the first configuration parameters.

Optionally, the first configuration parameter is a priority parameter. Further, the terminal determines an RSRP threshold according to the priority parameter, p_rx and p_tx, or the terminal determines an RSRP threshold according to the priority parameter and p_rx, or the terminal determines an RSRP threshold according to the priority parameter and p_tx, or the terminal determines an RSRP threshold according to the priority parameter only.

For example, the network configures the correspondence or table of p_tx, p_rx and RSRP thresholds, i.e. according to p_tx and p_rx, the corresponding RSRP threshold may be determined by combining the correspondence or table. In general, the higher the priority, the higher the corresponding RSRP threshold.

The network configures a priority parameter, when the terminal detects the terminal without interception capability, determines an RSRP threshold according to the priority parameter and p_tx, and the network can configure the priority corresponding to the priority parameter to be very low, for example, to be corresponding to priority 7 (i.e. lowest priority), so that the determined RSRP threshold is very low, thus the measured RSRP of the terminal without interception capability is very easy to be higher than the threshold, and resources reserved by the terminal without interception capability are excluded from a resource selection window, so that transmission collision between the terminal with interception capability and the terminal without interception capability is avoided.

For another example, the network configures a priority parameter, and when the terminal detects a terminal without interception capability, the terminal determines an RSRP threshold according to the priority parameter and p_rx, so that when the terminal with interception capability is performing resource exclusion, the RSRP threshold is determined by using the priority parameter, and no matter whether the priority corresponding to the terminal is high or low, so that the interference probability of the terminal without interception capability to the terminals with interception capability of all priority levels is the same, and the terminal with interception capability with high priority level is prevented from being interfered only. Further, the network may configure the priority level corresponding to the priority parameter to be very low, for example, to correspond to priority level 7 (i.e., the lowest priority level), so that the determined RSRP threshold is very low, which easily makes the measured RSRP of the terminal without interception capability higher than the threshold, and excludes the resources reserved by the terminal without interception capability from the resource selection window, thereby avoiding transmission collision between the terminal with interception capability and the terminal without interception capability.

For another example, the network configures a priority parameter, and when the terminal detects a terminal without interception capability, the terminal determines an RSRP threshold according to the priority parameter, so that the RSRP threshold determined when the terminal with interception capability performs resource exclusion is the same, and whether the priority corresponding to the terminal is high or low, so that the interference probability of the terminal without interception capability to the terminals with interception capability of all priority levels is the same, and the terminal with interception capability with high interference priority level is avoided. Further, the network may configure the priority level corresponding to the priority parameter to be very low, for example, to correspond to priority level 7 (i.e., the lowest priority level), so that the determined RSRP threshold is very low, which easily makes the measured RSRP of the terminal without interception capability higher than the threshold, and excludes the resources reserved by the terminal without interception capability from the resource selection window, thereby avoiding transmission collision between the terminal with interception capability and the terminal without interception capability.

For another example, when the network configures a priority parameter and the terminal detects a terminal without interception capability, an RSRP threshold is determined according to the priority parameter, p_tx and p_rx, and the network may configure the priority corresponding to the priority parameter to be very low, for example, to correspond to priority 7 (i.e. lowest priority), so that the determined RSRP threshold is very low, thus it is easy to make the measured RSRP of the terminal without interception capability be higher than the threshold, and the reserved resources of the terminal without interception capability are excluded from the resource selection window, so as to avoid transmission collision between the terminal with interception capability and the terminal without interception capability.

Example 4-2:

in this example, the first configuration parameter is an RSRP threshold.

And in the process of resource exclusion, if SCI sent by the terminal without interception capability is detected, the first configuration parameter, namely an RSRP threshold, is used for resource exclusion, namely the terminal measures the RSRP of the terminal without interception capability, and if the RSRP threshold is exceeded, transmission resources reserved by the terminal without interception capability are excluded from a resource selection window.

Therefore, as the RSRP thresholds adopted by the terminals with interception capability of all priorities are the same, the interference probability of the terminals without interception capability to the terminals with interception capability of all priorities is the same, and the situation that only the terminals with interception capability with high priority are interfered is avoided.

Further, the RSRP threshold may be set very low, so that the measured RSRP of the terminal without interception capability is easily higher than the threshold, and the resources reserved by the terminal without interception capability are excluded from the resource selection window, so that transmission collision between the terminal with interception capability and the terminal without interception capability is avoided.

In the present embodiment, a precondition is that a terminal without interception capability can be identified. The step S610 may further include: the second terminal device determines that the first terminal device is a terminal device without listening capability.

Optionally, the second terminal device determines that the first terminal device is a terminal device without interception capability in at least one of the following manners:

mode one: the second terminal equipment determines that the first terminal equipment is terminal equipment without interception capability according to the information field in the SCI of the first terminal equipment;

For example, SCI includes a 1-bit information field, and a value of 1 indicates a terminal having no interception capability, and a value of 0 indicates a terminal having interception capability.

Wherein, the SCI of the first terminal equipment can be a first-order SCI and/or a second-order SCI.

Mode two: the second terminal device determines that the first terminal device is a terminal device without interception capability according to the format of the SCI of the first terminal device.

For example, the SCI format includes a first format and a second format;

wherein the first format includes at least one of a first order SCI format (format) 1-a, a second order SCI format 2-a, and a second order SCI format 2-B.

Mode three: the second terminal device determines that the first terminal device is a terminal device without interception capability according to a scrambling sequence for scrambling the SCI bit sequence of the first terminal device;

for example, the information bit sequence of SCI, or the bit sequence after channel coding, may be scrambled, indicating a terminal with listening capability if the first sequence is used for scrambling, and indicating a terminal without listening capability if the second sequence is used for scrambling.

Mode four: the second terminal equipment determines that the first terminal equipment is the terminal equipment without interception capability according to the DMRS sequence of the PSCCH or PSSCH of the first terminal equipment;

For example, if the DMRS sequence of the PSCCH or PSSCH adopts a first sequence, it means a terminal having listening capability, and if the DMRS sequence adopts a second sequence, it means a terminal having no listening capability.

Mode five: when the second terminal device detects the PSCCH of the first terminal device in the first time-frequency resource set configured in the resource pool, the first terminal device is determined to be the terminal device without interception capability.

In this way, a first set of time-frequency resources may be configured in the resource pool, and terminals without listening capability may be configured to transmit within the first set of time-frequency resources. Accordingly, when other terminals detect a PSCCH (i.e., SCI) within the first set of time-frequency resources, it may be determined that the terminal transmitting the PSCCH is a terminal that has no listening capability.

The embodiment of the application also proposes a sidestream data transmission method, and fig. 7 is a schematic flowchart of a sidestream data transmission method 700 according to an embodiment of the application, where the method may alternatively be applied to the above-mentioned terminal device with interception capability and terminal device without interception capability. The method includes at least part of the following:

s710: the terminal equipment acquires the resource pool configuration information, and determines that the transmission priority of the sidestream data in the resource pool is not higher than the priority corresponding to the first priority threshold according to the first priority threshold.

Optionally, the resource pool configuration information includes the first priority threshold.

Optionally, the resource pool configuration information may include indication information, where the indication information is used to indicate that the terminal without interception capability allows data transmission in the resource pool.

Example 5 below corresponds to this sidestream data transmission scheme.

Example 5:

when the resource Chi Zhongyun Xu Suiji is selected, the resource pool configuration information includes a first priority threshold, and side line data with a priority higher than the first priority threshold is not allowed to be transmitted in the resource pool.

When the resource pool allows the terminals with interception capability (selecting transmission resources through interception) and the terminals without interception capability (acquiring transmission resources through random selection) to be used together, the terminals without interception capability select transmission resources, and as re-evaluation and pre-transmission detection cannot be performed, resource reselection cannot be performed, only other terminals with interception capability can be expected to avoid interference with the terminals without interception capability through re-evaluation or pre-transmission detection, and when the priority of the terminals with interception capability is higher than that of the terminals without interception capability, resource reselection cannot be triggered, so that interference between the terminals without interception capability and the terminals with interception capability with high priority is caused. Therefore, in the resource pool configuration information, the first priority threshold is configured, and the sidestream data with the priority higher than the first priority threshold is not allowed to be transmitted in the resource pool, so that interference of the terminal without interception capability to high-priority sidestream transmission can be avoided.

For example, the priority of the side line data is 8 levels, i.e., [0,7], where 0 represents the highest priority and 7 represents the lowest priority, and if the first priority threshold is p_thd=3 in the resource pool configuration information, then the side line data with priority level 0,1,2 (whose corresponding priority is higher than the priority corresponding to the first priority threshold) is not allowed to be transmitted in the resource pool, i.e., the priority of the side line data that can be supported by the resource pool is [3,7], so that interference of the terminal without interception capability to the side line data with priority level 0,1,2 is avoided.

The embodiment of the application also proposes a sidestream data transmission method, and fig. 8 is a schematic flowchart of a sidestream data transmission method 800 according to an embodiment of the application, where the method may alternatively be applied to the terminal device with interception capability. The method includes at least part of the following:

s810: under the condition that the channel occupancy rate (CBR, channel Busy Ratio) is lower than a first threshold, when the second terminal equipment detects that resource conflict occurs with the first terminal equipment, the second terminal equipment performs resource reselection; wherein the first terminal device comprises a terminal device without interception capability. The second terminal device comprises a listening capable terminal device.

Optionally, when the second terminal device detects that a resource conflict occurs with the first terminal device, and the second terminal device measures that the RSRP of the first terminal device is higher than the second threshold, the second terminal device performs resource reselection.

Optionally, the first threshold and the second threshold are determined according to network configuration information or pre-configuration information.

In the present embodiment, a precondition is that a terminal without interception capability can be identified. The step S810 may further include: the second terminal device determines that the first terminal device is a terminal device without listening capability. The specific identification manner is similar to that in the above embodiment 4, and will not be described here again.

Example 6 below corresponds to this sidestream data transmission scheme.

Example 6:

if the CBR is lower than the first threshold, when the terminal with interception capability detects that resource conflict occurs with the terminal without interception capability, the terminal with interception capability performs resource selection so as to avoid interference between the terminal with interception capability and the terminal without interception capability.

Or if the CBR is lower than the first threshold, when the terminal with interception capability detects that resource conflict occurs with the terminal without interception capability, and the RSRP of the terminal with interception capability measured by the terminal without interception capability is higher than the second threshold, the terminal with interception capability performs resource selection to avoid interference between the terminal with interception capability and the terminal without interception capability.

The first threshold and the second threshold may be determined according to network configuration information or pre-configuration information.

When the CBR measured by the terminal is below the first threshold, the system resources may be considered idle. At this time, the terminal detects that the resource conflict exists, and the terminal can be triggered to reselect the resource; because the system is idle, the probability of selecting idle resources in the process of resource reselection is high, so that interference between terminals can be avoided.
