Detailed ways

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. With regard to the embodiments in the present application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

Before introducing the technical solution of the present application, the relevant concepts of the present application are described below:

1. Network coverage in sideline communication (that is, communication based on sidelink technology)

In sideline communication, according to the network coverage of the communicating terminal, it can be divided into network coverage inner line communication, partial network coverage sideline communication, and network coverage outer line communication, respectively, as shown in Figure 1, Figure 2 and Figure 2. 3 shown.

As shown in FIG. 1 , in the inbound communication within the network coverage, all the terminals performing the lateral communication are within the coverage of the same network device, so that these terminals within the coverage of the same network device can receive the network device through the configuration signaling, so that sideline communication is performed based on the same sideline configuration.

As shown in Figure 2, when part of the network covers sideline communication, some terminals performing sideline communication are located within the coverage of the network device, and these terminals can receive the configuration signaling of the network device, and according to the configuration of the network device sideline communication. However, the terminal outside the network coverage cannot receive the configuration signaling of the network device. In this case, the terminal outside the network coverage will send the pre-configuration information and the terminal within the network coverage The information carried in the Physical Sidelink Broadcast Channel (PSBCH) determines the sideline configuration and performs sideline communication.

As shown in FIG. 3 , for communication outside the network coverage, all the terminals performing the lateral communication are located outside the coverage of the network, and all the terminals determine the lateral configuration according to the pre-configured information to perform the lateral communication.

2. D2D

Device-to-device communication is a D2D-based SL technology. Different from the traditional cellular system in which communication data is received or sent through network devices, device-to-device communication has higher spectral efficiency and lower transmission delay. The Internet of Vehicles system adopts the method of terminal-to-terminal direct communication, and two transmission modes are defined in the 3rd Generation Partnership Project (3GPP): the first mode and the second mode.

The first mode: the transmission resources of the terminal are allocated by the network device, and the terminal sends data on the sidelink according to the resources allocated by the network device; the network device can allocate resources for a single transmission to the terminal, or can allocate resources to the terminal. Semi-statically transmitted resources. As shown in FIG. 1 , the terminal is located within the coverage of the network, and the network device allocates transmission resources for sideline transmission to the terminal.

The second mode: the terminal selects a resource in the resource pool for data transmission. As shown in Figure 3, the terminal is located outside the coverage of the cell, and the terminal autonomously selects transmission resources in the preconfigured resource pool for sideline transmission; or as shown in Figure 1, the terminal autonomously selects transmission resources in the resource pool configured by the network to perform Sideline transmission.

3. NR-V2X

In NR-V2X, autonomous driving needs to be supported, so higher requirements are put forward for data interaction between vehicles, such as higher throughput, lower latency, higher reliability, larger coverage, More flexible resource allocation, etc.

In NR-V2X, unicast and multicast transmission methods are introduced. For unicast transmission, there is only one terminal at the receiving end. As shown in Figure 4, unicast transmission is performed between UE1 and UE2; for multicast transmission, the receiving end is all terminals in a communication group, or at a certain transmission All terminals within the distance, as shown in Figure 5, UE1, UE2, UE3 and UE4 form a communication group, in which UE1 sends data, and other UEs in the group are receivers; for broadcast transmission, the receiver is the sender. Any terminal around the terminal, as shown in FIG. 6 , UE1 is the transmitting terminal, and other UEs around it, namely, UE2-UE6 are all receiving terminals.

4. In LTE-V2X, the resource selection method based on listening

In LTE-V2X, full listening or partial listening is supported, wherein, full listening means that the terminal can listen to the data sent by other terminals in all time slots (or subframes) except the time slot in which data is sent; and Partial sensing is to achieve energy saving of the terminal. The terminal only needs to listen to part of the time slot or subframe, and selects resources based on the result of partial sensing.

Specifically, when the upper layer does not configure partial interception, that is, by default, complete interception is used to select resources. The standard (3GPP TS36.213) defines resource selection based on complete interception. Among them, when a new data packet arrives at time n, resource selection needs to be performed. Assuming that the terminal currently performing resource selection is Terminal 1, Terminal 1 will select a window [n+ Resource selection is performed within T1, n+T2] milliseconds, where T1≤4; _T2min (prio _TX )≤T ₂ ≤100, T _2min (prio _TX ) is a parameter related to priority, and the selection of T1 should be greater than that of the terminal The selection of T2 needs to be within the delay requirement of the service. For example, if the delay requirement of the service is 50ms, 20≤T2≤50, and the delay requirement of the service is 100ms, then 20≤T2≤100 , as shown in Figure 7 below, where T2=100. Terminal 1 detects sidelink control information (Sidelink Control Information, SCI) of other terminals on resource 1, indicating that resource 2 in the selection window is reserved, and the RSRP measured by terminal 1 on resource 1 exceeds the RSRP threshold, Then, the terminal excludes resource 2 in the selection window, that is, it considers resource 2 to be an unavailable resource. Conversely, for resource 4 in the selection window, if the terminal does not detect the SCI on the corresponding resource 3 in the listening window, it means that resource 4 is not reserved by other terminals. Therefore, terminal 1 can reserve this resource 4, if The service to be transmitted by the terminal 1 is a periodic service, then the terminal 1 can reserve resources 5-7.

In the way of complete listening, the process of the terminal selecting resources in the selection window includes:

The terminal will select all available resources in the window as a set A, and the terminal will exclude the resources in set A:

1. If the terminal has no listening result in some subframes in the listening window, the resources on the subframes corresponding to these subframes in the selection window are excluded.

2. If the terminal detects a Physical Sidelink Control Channel (PSCCH) within the listening window, it measures the reference signal received power (Reference Signal) of the Physical Sidelink Shared Channel (PSCCH) scheduled by the PSCCH. Signal Received Power, RSRP), if the measured PSSCH-RSRP is higher than the PSSCH-RSRP threshold, and the resources reserved according to the reserved information in the PSCCH are in resource conflict with the resources to be used by the terminal in the selection window, Then the terminal excludes the resource from the set A. The selection of the PSSCH-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.

3. If the number of remaining resources in set A is less than 20% of the total number of resources, the terminal will increase the PSSCH-RSRP threshold by 3dB, and repeat steps 1-2 until the number of remaining resources in set A is greater than 20% of the total number of resources. 20%.

4. The terminal performs sidelink reference signal received power (Sidelink Received Signal Strength Indicator, S-RSSI) detection on the remaining resources in set A, and sorts them according to the energy level. Number of resources) resources are put into set B.

5. The terminal selects a resource from set B with moderate probability for data transmission.

When the high-level configuration selects based on partial interception, the terminal based on partial interception selects at least Y resources in the selection window, and judges whether at least Y resources can be used as candidate resources according to the interception result, and puts them in set B if possible. , if the number of elements in set B is greater than or equal to 20% of the total number of resources, set B is reported to the upper layer.

5. In NR-V2X, resource selection method based on complete interception

NR-V2X supports periodic services and aperiodic services. In the current standard, the resource selection method based on complete listening is discussed, which is similar to the resource selection method based on complete listening in LTE-V2X. The specific listening process and resources are The selection process can be found in 3GPP TS38.214. Among them, in LTE-V2X, when the terminal selects transmission resources, it will send data on these resources, but there may be two terminals that select the same transmission resources. At this time, resource conflicts will occur and system performance will be reduced. In order to solve For this problem, the pre-emption and re-evaluation mechanisms are introduced in NR-V2X, so that the terminal can determine whether there is a resource conflict with other terminals before using the selected resource. If there is no conflict, you can Continue to use the selected transmission resource. If there is a resource conflict, avoidance and resource reselection need to be performed according to the corresponding mechanism to avoid resource conflict.

1. Re-evaluation mechanism

After the terminal completes resource selection, resources that have been selected but not indicated by sending sideline control information may still be reserved by other terminals with burst aperiodic services, resulting in resource collision. In response to this problem, a re-evaluation mechanism is proposed, that is, the terminal continues to listen to the sideline control information after completing the resource selection, and re-evaluates the selected but not indicated resources at least once.

As shown in FIG. 8 , resources w, x, y, z, and v are time-frequency resources that have been selected by the terminal, and resource x is located in time slot m. For the resources y and z that the terminal will send the sideline control information for the first time in resource x (resource x has been indicated by the sideline control information in resource w before). The terminal performs resource listening at least once in the time slot _mT3 , that is, determines the selection window and the listening window, and excludes the resources in the selection window to obtain a candidate resource set. If resource y or z is not in the candidate resource set, the terminal reselects the time-frequency resources in resources y and z that are not in the candidate resource set, and can also reselect any resource that has been selected but not indicated by sending sideline control information, for example Any number of resources y, z, and v. _The above T3 depends on the processing capability of the terminal.

2. Pre-emption mechanism

In NR-V2X, the conclusions about the pre-emption mechanism are all described from the perspective of the terminal whose resources are preempted. After completing the resource selection, the terminal continues to listen to the sideline control information, and if the time-frequency resources that have been selected and indicated by sending the sideline control information meet the following three conditions, resource reselection is triggered:

(1) The resources reserved in the detected sideline control information overlap with the resources selected and indicated by the terminal, including full overlap and partial overlap.

(2) The RSRP of the PSCCH corresponding to the sideline control information detected by the terminal or the RSRP of the PSSCH scheduled by the PSCCH is greater than the SL RSRP threshold.

(3) The priority carried in the detected sideline control information is higher than the priority of the data to be sent by the terminal.

As shown in FIG. 9 , resources w, x, y, z, and v are time-frequency resources that have been selected by the terminal, and resource x is located in time slot m. For the resources x and y indicated by the sideline control information that the terminal is about to send in the time slot m and which have been indicated by the sideline control information sent by the terminal before. The terminal performs resource listening at least once in time slot _mT3 to determine a candidate resource set. If the resource x or y is not in the candidate resource set (satisfying the above conditions 1 and 2), further judge whether the resource x or y is not in the candidate resource set due to the indication of the sideline control information carrying the high priority (satisfying the above condition 3) ), if yes, the terminal performs resource re-selection, and re-selects the time-frequency resources in x and y that satisfy the above three conditions.

As mentioned above, in the topic of R17 side link enhancement, it is necessary to study the handheld terminal. The handheld terminal is limited by the battery capacity, that is, the handheld terminal is a terminal that needs energy saving. Therefore, how to realize the energy saving of this type of terminal is the main problem. The technical problem to be solved urgently in the application, in order to solve this technical problem, the inventive concept of the present application is to carry the relevant information of the energy-saving terminal and/or the relevant information of different energy-saving levels in the configuration information of the resource pool.

The technical solution of the present application will be elaborated below:

FIG. 10 is a flowchart of a wireless communication method provided by an embodiment of the present application. As shown in FIG. 10 , the method includes the following steps:

Step S1010: The first terminal acquires transmission resources in a resource pool, and the configuration parameters of the resource pool include: related information of the energy-saving terminal and/or related information of different energy-saving levels.

Step S1020: The first terminal performs sideline transmission on the transmission resource.

Optionally, the present application can be applied to the sideline communication within the network coverage as shown in FIG. 1 , also can be applied to the sideline communication covered by the partial network as shown in FIG. The sideline communication outside the coverage of the network is not limited in this application.

Optionally, the present application may be applicable to the above-mentioned two transmission modes defined by 3GPP, that is, the first mode and the second mode, which are not limited in the present application. In the first mode, the above-mentioned transmission resources are allocated to the first terminal by the network device. In the second mode, the first terminal autonomously selects transmission resources from a preconfigured resource pool; or, the first terminal may autonomously select transmission resources from a network-configured resource pool.

It should be understood that R17 involves energy-saving terminals, such as handheld terminals, so in this application, the terminals will be divided into power saving levels.

It should be understood that, in this application, the power saving level is also described as a power saving state, a power saving mode, or a power saving state level, etc., which is not limited in this application.

Optionally, for any terminal, the energy saving level of the terminal is determined according to the capability and/or remaining power of the terminal. For example: Table 1 shows the corresponding relationship between the energy saving level and the remaining power:

Table 1

Energy saving class	Remaining power P
0	P≥80%
1	50%≤P<80%
2	20%≤P<50%
3	P≤20%

Optionally, for any terminal, the capability of the terminal may be measured by various software and hardware parameters of the terminal, and the present application does not limit the software and hardware parameters.

It should be understood that, in this application, the remaining power of the terminal is also described as the battery state of the terminal, which is not limited in this application.

Optionally, the energy saving level of each terminal in this application may be predefined, specified in a protocol or configured by a network, which is not limited in this application.

Optionally, the definition of the energy saving level in this application is as follows:

In an implementation manner, two energy-saving levels may be introduced in the present application, and one energy-saving level corresponds to a terminal that does not require energy saving or a terminal that does not require energy saving, such as a vehicle-mounted terminal. Another energy saving level corresponds to a terminal requiring energy saving or a terminal having energy saving requirement, such as a handheld terminal. Optionally, one of the above energy-saving levels may be defined as energy-saving level 0, and another energy-saving level may be defined as energy-saving level 1. Of course, one of the above energy-saving levels may also be defined as energy-saving level 1, and another energy-saving level may be defined as energy-saving level 0, which is not limited in this application.

Another achievable way is that more energy-saving grades can be introduced in this application, for example, four energy-saving grades are introduced, and energy-saving grade 0 corresponds to terminals that do not need energy-saving or terminals that do not need energy-saving, such as vehicle-mounted terminals, etc.; energy-saving grades 1. Energy-saving level 2 and energy-saving level 3 correspond to terminals that need to be considered for energy saving, and different energy-saving levels correspond to different terminal capabilities and/or corresponding to different remaining power levels.

Optionally, the stronger the capability of the terminal and/or the more remaining power, the lower the energy saving level of the terminal. The weaker the capability of the terminal and/or the less the remaining power, the higher the energy saving level of the terminal. Alternatively, the stronger the capability of the terminal and/or the more remaining power, the higher the energy saving level of the terminal. The weaker the capability of the terminal and/or the less the remaining power, the lower the energy saving level of the terminal. This application does not limit this.

Optionally, the relevant information of the energy-saving terminal and/or the relevant information of different energy-saving levels includes at least one of the following:

(1) First indication information. The first indication information is used to indicate whether the resource pool supports energy-saving terminals, or the energy-saving level supported by the resource pool, or the resource pool supports random resource selection, or the resource pool supports partial interception based resource selection method.

(2) Second indication information, the second indication information is used to indicate whether the energy-saving terminal supports the re-evaluation mechanism and/or the pre-preemption mechanism, or whether different energy-saving levels support the re-evaluation mechanism and/or the pre-preemption mechanism respectively.

(3) Transmission parameters corresponding to different energy-saving levels respectively.

(4) Third indication information, where the third indication information is used to indicate resource selection modes corresponding to the energy-saving terminal, or indicate resource selection modes corresponding to different energy-saving levels respectively.

(5) The minimum number of subframes or time slots included in the selection window corresponding to different energy saving levels.

(6) Listening parameters corresponding to different energy-saving levels respectively.

(7) First ratios corresponding to different energy saving levels respectively, where the first ratio is a threshold value of the ratio of the number of resources in the candidate resource set of the terminal to the number of resources in the selection window of the terminal.

(8) RSRP threshold values or RSRP offset values corresponding to different energy saving levels respectively, the RSRP offset value is an offset value relative to the default RSRP threshold value, and the default RSRP threshold value is no energy saving The RSRP threshold value corresponding to the terminal.

For item (1):

It should be understood that for terminals that require energy saving, terminals that do not require energy saving, or terminals of different energy saving levels, in order to achieve the purpose of energy saving of the terminals, whether they support the re-evaluation mechanism and/or pre-preemption mechanism, the transmission parameters involved, the corresponding The configuration of the resource selection method, the minimum number of subframes or time slots included in the selection window, the corresponding listening parameters, the corresponding first ratio, the RSRP threshold value or the RSRP offset value are different, for example: for For a terminal that needs to consider energy saving, resource selection can be performed based on random resource selection or based on a partial listening result, while for a terminal that does not need to consider energy saving, resource selection is performed according to the complete listening result. Alternatively, when a terminal requiring energy saving and a terminal not requiring energy saving use the same resource pool, the terminal not requiring energy saving needs to perform special processing on the terminal requiring energy saving, such as being unable to preempt the transmission resources reserved by the energy saving terminal. Therefore, in this case, for any terminal, it needs to know whether its corresponding resource pool supports energy-saving terminals, or indicates the energy-saving level supported by the resource pool, or indicates that the resource pool supports random resource selection, or indicates that the resource pool supports The resource selection method for partial listening. Based on this, in this application, the configuration parameters of the resource pool may include the above-mentioned first indication information.

For example, the value of the first indication information is 1, or TRUE, or enabled, indicating that the resource pool supports energy-saving terminals, and the value of the first indication information is 0, or FALSE, or disabled, indicating that the resource pool does not support energy-saving terminals . Alternatively, the first indication information takes a value of 1, or TRUE, or enabled, indicating that the resource pool does not support energy-saving terminals, and the first indication information takes a value of 0, or FALSE, or disabled, indicating that the resource pool supports energy-saving terminals .

For another example: there are a total of 4 energy-saving levels determined according to pre-definition, protocol regulations or network configuration, namely energy-saving level 0, energy-saving level 1, energy-saving level 2, and energy-saving level 3. The first indication information may indicate that the resource pool supports at least A power saving class such as support for power saving classes 2 and 3.

Another example: the first indication information indicates that a random resource selection method or a resource selection method based on partial listening is supported, and these two resource selection methods are usually the resource selection methods adopted by the energy-saving terminal. Therefore, this situation is equivalent to an implicit Indicates that the resource pool supports energy-saving terminals.

For item (2):

In NR-V2X, a re-evaluation and pre-preemption mechanism is introduced, that is, after the terminal selects a transmission resource, it still needs to listen before using the resource to determine whether the selected transmission resource conflicts with other terminals. If a conflict occurs You need to re-select the resource. Therefore, in the process of re-evaluation and pre-preemption, the terminal needs to perform continuous channel listening before transmission, and this process also consumes energy. For energy-saving terminals, this continuous listening process is not suitable. Therefore, for a terminal that needs energy saving, the second indication information in the configuration information of the resource pool can indicate whether to support the re-evaluation and/or pre-preemption mechanism for the terminal in the energy-saving state, or whether different energy-saving levels support the re-evaluation mechanism respectively. and/or pre-preemption mechanism.

For example, the second indication information takes a value of 1, or TRUE, or enabled, indicating that the re-evaluation and/or pre-preemption mechanism is supported for the energy-saving terminal; the second indication information takes a value of 0, or FALSE, or disabled, indicating that the energy-saving terminal supports The endpoint does not support re-evaluation and/or pre-preemption mechanisms. Alternatively, the second indication information takes a value of 1, or TRUE, or enabled, indicating that the re-evaluation and/or pre-preemption mechanism is not supported for the energy-saving terminal; the second indication information takes a value of 0, or FALSE, or disabled, indicating that for the energy-saving terminal Energy efficient terminals support re-evaluation and/or pre-preemption mechanisms.

For another example: a total of 4 energy-saving state levels of the terminal are determined according to pre-definition, protocol regulations or network configuration, namely energy-saving level 0, energy-saving level 1, energy-saving level 2, and energy-saving level 3, and the second indication information indicates different energy-saving levels respectively. Whether to support re-evaluation and/or pre-preemption mechanisms. For example, the second indication information is 4 bits, each bit corresponds to one energy saving level, and the value of each bit is 1 or 0, respectively indicating whether the re-evaluation and/or pre-preemption mechanism is supported or not. For example, the value of the bit sequence is 1111, indicating that the terminals of the four energy-saving levels support the re-evaluation and/or pre-preemption mechanism, and the value of 0000 means that the terminals of the four energy-saving levels do not support re-evaluation and/or pre-preemption Mechanism, a value of 1100 indicates that the terminals of energy saving level 0 and 1 support the re-evaluation and/or pre-preemption mechanism, and the terminals of energy-saving levels 2 and 3 do not support the re-evaluation and/or pre-preemption mechanism.

For item (3):

Optionally, the transmission parameters include at least one of the following: maximum transmit power, power control parameters, and maximum number of transmissions, but are not limited thereto.

In order to achieve the purpose of energy saving, the maximum transmit power of the terminal may be reduced. Therefore, in the configuration information of the resource pool, different maximum transmit powers can be configured for different energy saving levels. For example, two energy-saving levels or more are introduced in this application. When two energy-saving levels are introduced, the corresponding relationship between different energy-saving levels and the maximum transmit power is shown in Table 2. When four energy-saving levels are introduced , the corresponding relationship between different energy-saving levels and the maximum transmit power is shown in Table 3:

Table 2

0	twenty three
1	20

Energy saving class	Maximum transmit power P_ps_max (dBm)
0	twenty three

It should be noted that the correspondence between the energy saving level and the maximum transmission power is not limited to the correspondence shown in Table 2 and Table 3.

In the NR-V2X system, the terminal can perform power control according to the sidelink path loss or downlink path loss. Specifically, the transmit power of the terminal is determined by the following formula (1):

P _PSSCH (i)=min(P _CMAX ,P _MAX,CBR ,min(P _PSSCH,D (i),P _PSSCH,SL (i)))[dBm](1)

The power based on the downlink path loss is determined by equation (2):

The power based on the downlink path loss is determined by equation (3):

P _CMAX represents the configured maximum transmit power, P _{MAX, CBR} represents the configured maximum transmit power based on the channel occupancy ratio (Channel Busy Ratio, CBR),

Indicates the number of physical resource blocks (Physical Resource Block, PRB) occupied by the PSSCH, and PO _,D , PO _,SL , α _D and α _SL are power control parameters.

At least one of different PO _,D , PO _,SL , _αD , and _αSL may be configured for terminals in different energy-saving states. The following uses PO _{, SL} and _αSL as examples for description.

In NR-V2X, the value range of PO _{, SL} is an integer between [-16, 15]; the value range of _αSL is {0, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1} , therefore, corresponding PO _{, SL} and α _SL can be configured for terminals of different energy-saving levels. For example, when there are two energy-saving levels, the corresponding PO _{, SL} and _αSL are shown in Table 4 and Table 5, respectively, and when there are four energy-saving levels, the corresponding PO _{, SL} and _αSL are shown in Table 4 and Table 5, respectively. shown in Table 6 and Table 7.

In NR-V2X, the maximum number of transmissions for one sideline data, that is, transmitted through sideline communication or sidelink technology, is 32 to ensure transmission reliability. However, the more times the terminal sends data, the more power it consumes. Therefore, for different energy saving levels, different maximum transmission times can be configured to achieve the purpose of energy saving.

For example, the configuration information of the resource pool includes the MaxNumTransmission parameter, which represents the maximum number of transmissions of a sideline data. For example, when the energy saving level is two, the corresponding relationship between this parameter and the energy saving level is shown in Table 8. When the energy saving level is When there are four, the corresponding relationship between this parameter and the energy saving level is shown in Table 9:

For item (4):

Optionally, a resource selection method based on full listening can be used for terminals that do not need energy saving, and a random resource selection method or a resource selection method based on partial listening can be used for terminals requiring energy saving. Therefore, the configuration parameters of the resource pool may include third indication information, where the third indication information is used to indicate resource selection modes corresponding to the energy-saving terminal, or resource selection modes corresponding to different energy-saving levels respectively.

For example, the third indication information indicates that the energy-saving terminal adopts a random resource selection manner, or adopts a resource selection based on partial listening.

For another example, the third indication information indicates that the terminal of energy saving level 1 adopts the resource selection method based on partial listening, the terminals of energy saving level 2 and 3 adopt the random resource selection method, and the terminal of energy saving level 0 adopts the resource selection method based on full listening. Way.

For item (5):

As described above, the terminal based on partial listening selects at least Y time slots (or subframes) in the selection window, and judges whether resources on at least Y time slots (or subframes) can be used as candidate resources according to the listening result , where Y is the minimum number of subframes or time slots determined by the terminal in the selection window. For example, the selection window is [n+T1,n+T2], the terminal determines at least Y time slots (or subframes) in the selection window, and determines the at least Y subframes on the at least Y subframes according to the listening result in the listening window resources are available. The corresponding relationship between the energy saving level and the minimum number of subframes or time slots (minNumCandidateSF) determined in the selection window may be configured. For example, when there are two energy-saving levels, the corresponding relationship between the energy-saving level and the minimum number of subframes or time slots (minNumCandidateSF) determined in the selection window is shown in Table 10. When there are four energy-saving state levels, energy saving The corresponding relationship between the level and the minimum number of subframes or time slots (minNumCandidateSF) determined in the selection window is shown in Table 11:

For item (6):

Optionally, the listening parameters include any of the following: a parameter for determining a listening time slot or a listening subframe in the listening window, a parameter for determining the listening duration in the listening window, using The parameter used to determine the end position of the listening window, and the parameter used to determine the starting position of the listening window.

When the terminal performs partial listening, it needs to listen to the subframes corresponding to n-k*Pstep, where n represents the moment of resource selection, Pstep is a constant or a configuration parameter of the resource pool, and k is determined by the resource pool configuration parameter gapCandidateSensing. This parameter gapCandidateSensing is used to indicate which time slots or subframes need to be monitored. In LTE-V2X, this parameter is a bit sequence with a length of 10. In the above formula, k indicates that the value of the kth bit of the parameter gapCandidateSensing is 1. In NR-V2X, when the resource pool supports energy-saving terminals, the parameter gapCandidateSensing can be configured as a parameter related to the energy-saving level. For example, configure the corresponding parameter gapCandidateSensing for different energy saving levels.

For example, when the system supports two energy-saving levels, the configuration parameter gapCandidateSensing corresponds to the energy-saving level as shown in Table 12. When the system supports four energy-saving levels, the configuration parameter gapCandidateSensing corresponds to the energy-saving level as shown in Table 13.

If only aperiodic services are supported in the resource pool, the terminal cannot know the arrival time of the service, and the terminal of the aperiodic service will not reserve transmission resources for the transmission of the next data block, but will only reserve the transmission resources for the retransmission of the current data block. Therefore, the terminal cannot determine the candidate resource set based on the past listening results. Usually, the terminal will only listen when the service arrives, and the listening duration is W, and the resource selection is performed according to the listening result within the duration W. As shown in Figure 11, the terminal needs to perform resource selection at time n. , if the resource selection is triggered when data arrives, the terminal determines that the listening window is [n+t1,n+t2], and the terminal determines the transmission resource in the selection window according to the listening result in the listening window.

Optionally, since the longer the listening duration is, the greater the power consumption of the terminal is, and the listening duration is determined by the parameter used to determine the listening duration in the listening window, so in this application, it can be Different power saving levels configure different parameters for determining the listening duration within the listening window.

Optionally, as shown in FIG. 11 , usually t1 is determined according to the processing time of the terminal, so the listening duration depends on the end position of the listening window, as shown in t2 in FIG. 11 . Similarly, since the longer the listening duration, Then the power consumption of the terminal is larger, and the end position of the listening window is determined by the parameters used to determine the end position of the listening window. Therefore, in this application, different energy saving levels can be configured with different parameters for determining the listening window. Parameter for the end position of the window. Similarly, it is assumed that the end position of the listening window is determined, so the listening duration depends on the starting position of the listening window, and since the longer the listening time is, the greater the power consumption of the terminal will be, and the starting position of the listening window will be higher. is determined by the parameters used to determine the starting position of the listening window, so in the present application, different parameters for determining the starting position of the listening window can be configured for different energy saving levels.

For item (7):

As mentioned above, in LTE-V2X based on the resource selection method of full listening, if the number of remaining resources in set A is less than 20% of the total number of resources, the terminal will increase the threshold of PSSCH-RSRP by 3dB, and repeat steps 1- 2. Until the number of remaining resources in set A is greater than 20% of the total number of resources. In NR-V2X, this ratio is a parameter related to priority, and the range of possible values is {20%, 30%, 50%}. For an energy-saving terminal, if steps 1-2 are continuously performed for many times, the problem of excessive power consumption is bound to occur. Therefore, the present application can configure the corresponding relationship between different energy-saving levels and the above-mentioned first ratio.

For example, the system supports two energy-saving levels, and the corresponding relationship between different energy-saving levels and the first ratio is shown in Table 14. The system supports four energy-saving levels, and the corresponding relationship between different energy-saving levels and the first ratio is shown in Table 15.

Table 14

Energy saving class	first ratio
0	0.2
1	0.1

Table 15

Energy saving class	first ratio
0	0.2
1	0.1
2	0.05
3	0.02

Optionally, the higher the energy-saving level value, the more energy-saving the terminal needs, and the lower the corresponding first ratio, that is, the higher the ratio of the number of resources in the candidate resource set after resource exclusion to the number of resources in the selection window. It is easy to exceed the first ratio, so there is no need to increase the RSRP threshold for iterative processing.

For item (8):

As mentioned above, in LTE-V2X, if the terminal detects the PSCCH in the listening window, it measures the RSRP of the PSSCH scheduled by the PSCCH, and if the measured PSSCH-RSRP is higher than the PSSCH-RSRP threshold (that is, the RSRP threshold), And if there is a resource conflict between the reserved transmission resource determined according to the reservation information in the PSCCH and the resource to be used by the terminal in the selection window, the terminal excludes the resource from the set A. The selection of the PSSCH-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. In NR-V2X, when the terminal detects the PSCCH within the listening window, it can measure the RSRP of the PSCCH and compare it with the PSCCH-RSRP threshold, or measure the RSRP of the PSSCH scheduled by the PSCCH and compare it with the PSSCH-RSRP threshold.

In a possible implementation manner, in order to achieve the purpose of energy saving, different RSRP thresholds or different RSRP offset values delta_RSRP may be configured for different energy saving levels. During the listening process, the terminal determines according to the energy saving level corresponding to the terminal. Corresponding RSRP threshold value. Optionally, the RSRP threshold value or the RSRP offset value delta_RSRP is related to the priority. The new RSRP threshold determined according to this parameter is: RSRP_PSstate=RSRP+delta_RSRP; where RSRP represents the default RSRP threshold, and the default RSRP threshold corresponds to the terminal that does not need energy saving (or the terminal whose energy saving level is 0) The default RSRP threshold value is included in the configuration parameters of the resource pool. This threshold value is used by terminals that do not need energy saving during the listening process. For energy-saving terminals, the RSRP offset value can be configured. The default RSRP threshold value and the RSRP offset value can determine the RSRP threshold value used by the energy-saving terminal in the listening process.

For example, two energy-saving levels or more are introduced in this application. When two energy-saving levels are introduced, the corresponding relationship between different energy-saving levels and RSRP offset values is shown in Table 16. When four energy-saving levels are introduced The corresponding relationship between different energy saving levels and RSRP offset values is shown in Table 17. The table only exemplifies the RSRP offset values of different energy saving levels corresponding to one priority level. For different priority levels, you can configure corresponding The corresponding relationship between the energy saving level and the RSRP offset value (or RSRP threshold value).

In yet another possible implementation manner, different RSRP thresholds or different RSRP offset values may be configured for different energy saving levels, and the RSRP thresholds or RSRP offset values are used to determine that a terminal that does not need energy saving is in the listening process RSRP thresholds used for terminals with different energy-saving levels. As mentioned above, for energy-saving terminals, in order to achieve the purpose of energy saving, it is necessary to avoid re-evaluation and pre-preemption processing of energy-saving terminals as much as possible. Therefore, it is possible to avoid the energy-saving terminal from performing re-evaluation and pre-preemption judgment, and re-selecting resources. Therefore, terminals that do not need energy saving should try to avoid preempting the resources of energy-saving terminals. In this case, for the RSRP threshold or RSRP offset value of terminals that do not need energy saving, the corresponding RSRP threshold or RSRP threshold can be configured for energy-saving terminals or different energy-saving levels. RSRP offset value. When the terminal that does not need energy saving is in the listening process, the corresponding RSRP threshold may be determined according to the energy saving level of the transmitting end corresponding to the PSCCH detected in the listening window. Optionally, the RSRP threshold value or the RSRP offset value is related to the priority level. The RSRP offset value is used to determine the RSRP threshold used for the energy-saving terminal during the listening process. The new RSRP threshold determined according to this parameter is: RSRP_PSstate=RSRP+delta_RSRP; where RSRP represents the default RSRP threshold, and the default RSRP threshold is the terminal that does not need energy saving during the listening process (or energy saving level). The RSRP threshold value corresponding to the terminal that is 0); the default RSRP threshold value is included in the resource pool configuration parameters. For energy-saving terminals, the RSRP offset value can also be configured, according to the default RSRP threshold value and RSRP threshold The value of the RSRP threshold used for the energy-saving terminal during the listening process can be determined.

For the RSRP thresholds configured for different energy saving levels, when a terminal that does not require energy saving detects the PSCCH during the listening process, and learns the energy saving level corresponding to the transmitting end of the PSCCH (for example, obtain the energy saving corresponding to the terminal through the indication information in the SCI) level), then the terminal that does not need energy saving determines the RSRP threshold value corresponding to the terminal that does not need energy saving according to the energy saving level, and compares the RSRP measurement value for the PSCCH transmitter with the RSRP threshold value, if it is higher than the threshold value , the resources reserved by the terminal are excluded from the selection window.

For example, two energy-saving levels or more are introduced in this application. When two energy-saving levels are introduced, the corresponding relationship between different energy-saving levels and the RSRP threshold value is shown in Table 18. When four energy-saving levels are introduced , the corresponding relationship between different energy saving levels and the RSRP threshold value is shown in Table 19. The table only exemplarily shows the RSRP thresholds of different energy saving levels corresponding to one priority level. For different priority levels, the corresponding relationship between the corresponding energy saving levels and RSRP thresholds (or RSRP offset values) can be configured.

It should be noted that, for different energy-saving levels in Tables 2 to 19, the values on the right side of the tables may be different, and of course they may be the same, which is not limited in this application.

To sum up, in this application, the configuration information of the resource pool carries the relevant information of the energy-saving terminal and/or the relevant information of different energy-saving levels. Thus, the purpose of terminal energy saving can be achieved. For example, when the configuration information of the resource pool carries the first indication information, a terminal that does not need energy saving needs to perform special processing on the energy saving terminal, such as being unable to preempt the transmission resources reserved by the energy saving terminal, so as to achieve the purpose of energy saving. When the configuration information of the resource pool carries the second indication information, some energy-saving terminals may not support the re-evaluation and/or pre-preemption mechanism, so as to achieve the purpose of energy saving. For a terminal with a higher energy saving level, its maximum transmit power, power control parameters, and maximum transmission times are smaller, so that the purpose of energy saving can be achieved. When the configuration information of the resource pool carries the third indication information to indicate that the energy-saving terminal adopts a random resource selection method, or a resource selection method based on partial listening, the purpose of energy saving can also be achieved. When the energy saving level is higher, the minimum number of subframes or time slots in the listening window is smaller, and the purpose of energy saving can also be achieved. When the energy saving level is higher, the listening duration is shorter, and the purpose of energy saving can also be achieved. When the energy saving level is higher, the corresponding first ratio is smaller, and the purpose of energy saving can also be achieved. When the energy saving level is higher, the RSRP threshold value used by the energy-saving terminal during the listening process is higher, or the RSRP threshold value used by the energy-saving terminal during the listening process for the terminal that does not need energy saving is lower, which can also achieve energy saving. the goal of.
