Detailed Description
So that the manner in which the features and elements of the present embodiments can be understood in detail, a more particular description of the embodiments, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.
The D2D communication is based on SL transmission technology, and unlike the traditional cellular system in which the communication data is received or sent through the base station, the car networking system adopts the D2D communication mode (i.e. the device-to-device direct communication mode), so that the communication system has higher spectral efficiency and lower transmission delay. For D2D communication, the Third Generation Partnership Project (3 GPP) defines two modes of transmission: a first mode (also referred to as mode a) and a second mode (also referred to as mode B). The first mode is that the network device allocates transmission resources for the terminal device, and the second mode is that the terminal device autonomously selects transmission resources.
For the first mode: as shown in fig. 1, the transmission resource of the terminal device is allocated by the base station, and the terminal device transmits data on the sidelink according to the resource allocated by the base station; the base station may allocate resources for single transmission to the terminal device, or may allocate resources for semi-static transmission to the terminal device.
For the second mode: as shown in fig. 2, the terminal device selects a transmission resource from the resource pool to transmit data.
In LTE-V2X, transmission mode 3 and transmission mode 4 are introduced, where transmission mode 3 corresponds to the first mode and transmission mode 4 corresponds to the second mode. In transmission mode 4, the terminal device determines the transmission resource by listening. The interception and resource determination process comprises the following steps: when a new data packet arrives at the time n and transmission resources need to be selected for data transmission, the terminal equipment selects the sidelink transmission resources within [ n + T1, n + T2] milliseconds (ms) according to the interception result in the past 1 second, wherein T1< (4); 20< ═ T2< ═ 100; and T1 should be greater than the processing delay of the terminal device, T2 needs to be within the delay requirement range of the service; if the delay requirement of the service is 50ms, 20< ═ T2< ═ 50; if the delay requirement of the service is 100ms, then 20< ═ T2< ═ 100. The process of the terminal device performing transmission resource selection in the resource selection window is as shown in fig. 3: the method comprises the following steps: the terminal device takes all available resources in the resource selection window as a set A, and the terminal device performs exclusion operation on the resources in the set A:
1) if the terminal device does not have the monitoring result in some subframes in the resource monitoring window, for example, the terminal device sends data on the subframe, and the subframe does not have the monitoring result, the resources on the corresponding subframe in the selection window are eliminated after the subframes are K periods;
2) if the terminal device detects a Physical Sidelink Control Channel (PSCCH) in the listening window, a Reference Signal Received Power (RSRP) of a corresponding Physical Sidelink Shared Channel (PSCCH) is higher than a threshold, and a next transmission resource reserved by the Control information conflicts with a resource of data to be transmitted by the terminal device, the terminal device excludes the resource from the set a.
3) If the number of the remaining resources in the set a is less than 20% of the total number of the resources in the resource selection window, the terminal device will raise the threshold of the psch-RSRP by 3dB, and repeat the above steps 1) -2) until the number of the remaining resources in the set a is greater than 20% of the total number of the resources in the resource selection window.
4) The terminal equipment detects the side-line Received Signal Strength Indicator (S-RSSI) of the rest resources in the set A, sorts the resources according to the energy level, and puts the 20 percent resource with the lowest energy (relative to the number of the resources in the set A) into the set B.
5) The terminal equipment selects a resource from the set B with medium probability for data transmission.
It should be noted that, the foregoing lists only a few main steps of the terminal device performing transmission resource selection within the resource selection window, and the detailed process of the terminal device performing transmission resource selection within the resource selection window may refer to the operation steps in 3GPP TS36.213 V15.3.0.
In NR-V2X, autonomous driving needs to be supported, and thus higher requirements are placed on data interaction between vehicles, such as higher throughput, lower latency, higher reliability, greater coverage, more flexible resource allocation, and the like.
In NR-V2X, a broadcast transmission scheme, a unicast transmission scheme, and a multicast transmission scheme are supported. As shown in fig. 4, the unicast transmission scheme has only one receiving end terminal device, and unicast transmission is performed between UE1 and UE 2. For the multicast transmission mode, the receiving end is all the terminal devices in a communication group or all the terminal devices within a certain transmission distance. For the multicast transmission scheme, as shown in fig. 5, UE1, UE2, UE3 and UE4 form a communication group, where UE1 is a terminal device at the transmitting end for transmitting data, and UE2, UE3 and UE4 in the group are all terminal devices at the receiving end for receiving data. For the broadcast transmission method, the receiving end may be any terminal device, as shown in fig. 6, UE1 is a terminal device on the transmitting end and is used for transmitting data, and other terminal devices around UE1, such as UE2, UE3, UE4, UE5, UE6, and UE7, are terminal devices on the receiving end and are used for receiving data.
In NR-V2X, a sidestream feedback channel is introduced in order to improve the reliability of the system. As shown in fig. 7, for a unicast transmission mode, a terminal device at a transmitting end transmits side line data (including PSCCH and PSCCH) to a terminal device at a receiving end, and the terminal device at the receiving end transmits feedback information, such as Hybrid Automatic Repeat reQuest (HARQ) feedback information, to the terminal device at the transmitting end; and the terminal equipment at the sending end judges whether data retransmission is needed or not according to the feedback information of the terminal equipment at the receiving end. The HARQ Feedback information is carried in a Sidelink Feedback Channel, such as a Physical Sidelink Feedback Channel (PSFCH).
In some embodiments, the sidestream feedback may be activated or deactivated by pre-configuration information or network configuration information. And if the side line feedback is activated, the terminal equipment at the receiving end receives the side line data sent by the terminal equipment at the sending end, and feeds back HARQ Acknowledgement (ACK)/Negative Acknowledgement (NACK) to the terminal equipment at the sending end according to the detection result. And the terminal equipment at the sending end sends retransmission data or new data according to the feedback information of the terminal equipment at the receiving end. If the sidestream feedback is deactivated, the terminal device at the receiving end does not need to send feedback information, and the terminal device at the sending end usually sends data in a blind transmission mode. For example, instead of determining whether retransmission data needs to be transmitted according to the feedback information of the terminal device at the receiving end, the terminal device at the transmitting end repeatedly transmits K times each piece of sideline data.
Under the condition that terminal equipment at a sending end sends data in a blind transmission mode, for example, data is sent in a broadcast mode or data is sent in a unicast mode, and side feedback is deactivated, a resource selection window can be determined in a resource selection window determining mode in the prior art; the determined ending position of the resource selection window in the time domain should meet the delay requirement of the service. However, if the sidelink feedback is activated, if the resource selection window is determined in the determination manner of the resource selection window in the prior art, the terminal device at the transmitting end may not select the retransmission resource when receiving the feedback information. For example, when the delay requirement of a service is 100ms, when the terminal device at the transmitting end transmits the service for the first time at time n, the maximum value of the determined resource selection window is (n +100) ms, if the transmission resource of the service for the first time is (n +90) th ms, the feedback information sent by the terminal device at the receiving end is (n +96) ms, and the feedback information is NACK; the selection range of retransmission resources of the terminal device at the transmitting end can only be [ n +97, n +100] ms. If the processing delay of the terminal device is 4ms, there is no resource available for retransmission in this case.
Based on the foregoing problems, an embodiment of the present application provides a method for determining a resource selection window, which may be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, LTE) System, an LTE Frequency Division Duplex (FDD) System, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication System, or a 5G System.
As shown in fig. 8, an optional processing flow of the method for determining a resource selection window by an application provided in the embodiment of the present application includes the following steps:
step S101, a terminal device determines a resource selection window according to a service attribute, wherein the resource selection window is used for the terminal device to select a sidelink transmission resource.
In some embodiments, the Service attribute includes at least one of a number of transmissions and a Quality of Service (QoS) of the Service. The QoS may include at least one of service priority, service reliability, and service latency; of course, QoS may also include other parameters that can characterize quality of service in addition to traffic priority, traffic reliability, and traffic latency. The service transmission times may be the maximum transmission times of the service; the service transmission times may also be preconfigured transmission times or network configured transmission times, for example, the resource pool configuration information includes transmission time information for indicating the maximum transmission times of the pschs transmitted in the resource pool; the number of service transmissions may also be the remaining number of transmissions of the service. Wherein, the remaining transmission times of the service are: the difference between the maximum number of transmissions of the traffic and the number of times the traffic has been transmitted.
In some embodiments, the determining, by the terminal device, a resource selection window according to the service attribute includes: and the terminal equipment determines the end position of the resource selection window on the time domain resource according to the service attribute.
In an optional implementation manner, the terminal device averagely allocates the size of the resource selection window within the time delay requirement range of the service according to the transmission times of the service. For example, the delay of a service needs 100ms, the number of transmissions of the service is 4, and the size of each resource selection window is 25 ms/4.
Correspondingly, the end position of each resource selection window on the time domain resource is the ratio of the time delay requirement of the service to the transmission times of the service; or, rounding up the ratio of the time delay requirement of the service to the transmission times of the service to obtain a value. It can be understood that, when the ratio of the delay requirement of the service to the transmission times of the service is an integer, the end position of each resource selection window on the time domain resource is: a ratio of a delay requirement of the service to a number of transmissions of the service. When the ratio of the time delay requirement of the service to the transmission times of the service is a non-integer, the end position of each resource selection window on the time domain resource is as follows: carrying out rounding operation on the ratio of the time delay requirement of the service to the transmission times of the service to obtain a value; the rounding operation may be an upward rounding operation or a downward rounding operation.
For example, the delay requirement of a service is 100ms, the number of times of transmission of the service is 4, and an optional diagram of the resource selection window is shown in fig. 9, where an end position of the first resource selection window on the time domain resource is (n +25) ms, an end position of the second resource selection window on the time domain resource is (n +50) ms, an end position of the third resource selection window on the time domain resource is (n +75) ms, and an end position of the fourth resource selection window on the time domain resource is (n +100) ms. For another example, the delay requirement of the service is 100ms, the number of times of service transmission is 3, the end position of the first resource selection window on the time domain resource is (n +33) ms, the end position of the second resource selection window on the time domain resource is (n +66) ms, and the end position of the third resource selection window on the time domain resource is (n +99) ms.
In another optional implementation, the terminal device allocates the size of the resource selection window according to an index within the time delay requirement range of the service according to the transmission times of the service. When the terminal equipment transmits data, the reliability of initial transmission is high, even reaches about 90%; therefore, the probability of data retransmission is very low, for example, about 10% of the traffic needs to perform data retransmission. In order to ensure that enough sidelink transmission resources are selectable in the initial transmission and reduce the probability of the conflict of the sidelink transmission resources, the end position of each resource selection window on the time domain can be configured according to an exponential proportion mode.
In specific implementation, the ending position of each resource selection window on the time domain resource may be a ratio of the delay requirement of the service to the first function; or, rounding the ratio of the delay requirement of the service to the first function to obtain a value. Optionally, the first function comprises 2kK is the kth transmission of the service, and k is a positive integer. For example, if the delay requirement of the service is 100ms, the number of times of transmission of the service is 4, and the end position of each resource selection window on the time domain resource is 100-100/2kK is 1, 2, 3; when k is 4, i.e., the last transmission, the end position of the resource selection window is (n +100) ms. It can be understood that, in the case that the number of times of transmission of the service is K, the end position of the resource selection window of the previous (K-1) times on the time domain is determined; and the end position of the resource selection window corresponding to the last service transmission on the time domain is the time corresponding to the time delay requirement of the service. Specifically, as shown in fig. 10, if the terminal device performs resource selection for the first resource transmission at time n and the maximum transmission time is 4 times, the end positions of the 4 resource selection windows in the time domain are (n +50) ms, (n +75) ms, (n +87) ms, and (n +100) ms, respectively.
In another optional implementation manner, the determining, by the terminal device, a resource selection window according to the service attribute includes:
the terminal equipment determines first configuration information and determines a resource selection window according to the first configuration information; the first configuration information includes end position information of a resource selection window related to the service attribute.
And under the condition that the first configuration information comprises the end position information of the resource selection window related to the service priority, namely the terminal equipment acquires the end position of the resource selection window and the end position of the resource selection window is related to the service priority, the terminal equipment determines the resource selection window according to the service priority and the end position information of the resource selection window related to the service priority. In specific implementation, if the service attribute is the service priority, for a service with a high service priority, a resource selection window with an early end position in a time domain may be selected, and an earlier transmission resource may be selected for the service, so that the service is sent to the terminal device at the receiving end as early as possible. Accordingly, for a service with a low service priority, a resource selection window with a late ending position in the time domain may be selected.
And under the condition that the first configuration information comprises the end position information of the resource selection window related to the service reliability, namely the terminal equipment acquires the end position of the resource selection window and the end position of the resource selection window is related to the service reliability, the terminal equipment determines the resource selection window according to the service reliability and the end position information of the resource selection window related to the service reliability. In specific implementation, if the service attribute is service reliability, the reliability of the service can be improved by transmitting the service for multiple times, so that for the service with high service reliability, a resource selection window with an early ending position in a time domain can be selected, thereby ensuring that the service has more retransmission opportunities and improving the reliability of the service. For a service with low service reliability, a resource selection window with a late ending position in the time domain may be selected.
And under the condition that the first configuration information comprises the end position information of the resource selection window related to the service time delay, namely the terminal equipment acquires the end position of the resource selection window and the end position of the resource selection window is related to the service time delay, the terminal equipment determines the resource selection window according to the service time delay and the end position information of the resource selection window related to the service time delay. In specific implementation, if the service attribute is service delay, different ending positions of resource selection windows can be configured for different service delays, and for a service with low service delay, a resource selection window with an early ending position in a time domain can be selected, so that an earlier transmission resource is selected for the service, and the service can be sent to a terminal device at a receiving end as early as possible. For the service with high service delay, the resource selection window with a late ending position in the time domain can be selected.
In some embodiments, the first configuration information may be pre-configuration information, which may also be configured by a network device.
The method for determining the resource selection window can ensure that the side link transmission resource can be selected when each service is transmitted (including first transmission and retransmission). Moreover, by configuring different ending positions of the resource selection window on the time domain for services with different service attributes, the requirements of the services, such as the transmission frequency requirements of the services and/or the QoS requirements of the services, can be met.
