Detailed Description
So that the manner in which the features and techniques of the embodiments of the present application can be understood in more detail, a more particular description of the application, briefly summarized below, may be had by reference to the appended drawings, which are not intended to be limiting of the embodiments of the present application.
D2D communication is based on SL transmission technology, and unlike conventional cellular systems in which communication data is received or transmitted through a base station, the internet of vehicles system adopts a D2D communication mode (i.e., a device-to-device direct communication mode), so that the system has higher spectral efficiency and lower transmission delay. For D2D communication, the third generation partnership project (Third Generation Partnership Project,3 GPP) defines two transmission modes: 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 resources of the terminal device are allocated by the base station, and the terminal device sends data on the side link according to the resources 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 one transmission resource in the resource pool to transmit data.
Transmission mode 3 and transmission mode 4 are introduced in LTE-V2X, wherein 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 resources by listening. The interception and resource determination processes are: when a new data packet arrives at a time n and a transmission resource is required to be selected for data transmission, the terminal equipment performs side uplink transmission resource selection within [ n+t1, n+t2] milliseconds (ms) according to a 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, and T2 needs to be within the range of the delay requirement of the service; if the latency requirement of the service is 50ms, 20 < = T2 < = 50; if the delay requirement of the traffic is 100ms, 20 < = T2 < = 100. The terminal device performs a transmission resource selection process within the resource selection window, as shown in fig. 3: comprising the following steps: the terminal equipment takes all available resources in the resource selection window as a set A, and the terminal equipment performs the elimination operation on the resources in the set A:
1) If the terminal equipment does not have a interception result in some subframes in the resource interception window, for example, the terminal equipment sends data on the subframes, if the terminal equipment does not have a interception result in the subframes, the resources on the subframes corresponding to the subframes in the selection window after K periods are eliminated;
2) If the terminal device detects a physical sidelink control channel (Physical Sidelink Control Channel, PSCCH) in the listening window, the reference signal received power (Reference Signal Received Power, RSRP) of the corresponding physical sidelink shared channel (Physical Sidelink Shared Channel, PSSCH) is higher than the threshold, and the next transmission resource reserved by the control information has resource conflict with the data to be sent by the terminal device, the terminal device excludes the resource in the set a.
3) If the number of resources remaining in set a is less than 20% of the total number of resources in the resource selection window, the terminal device may raise the threshold of PSSCH-RSRP by 3dB, and repeat steps 1) -2) above until the number of resources remaining in set a is greater than 20% of the total number of resources in the resource selection window.
4) The terminal equipment detects the side-row received signal strength indication (Sidelink Received Signal Strength Indicator, S-RSSI) of the rest resources in the set A, sorts the resources according to the energy, and puts the resources with the lowest energy (relative to the number of the resources in the set A) into the set B.
5) And the terminal equipment selects one resource from the set B with equal probability to transmit data.
It should be noted that the foregoing only lists a few main steps of the terminal device for selecting transmission resources in the resource selection window, and the detailed procedure of the terminal device for selecting transmission resources in the resource selection window may refer to the operation steps in 3GPP TS36.213 V15.3.0.
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.
In NR-V2X, a broadcast transmission mode, a unicast transmission mode and a multicast transmission mode are supported. For the unicast transmission scheme, as shown in fig. 4, only one terminal device of the receiving end performs unicast transmission between UE1 and UE 2. For multicast transmission, the receiving end is all the terminal devices in a communication group or all the terminal devices in a certain transmission distance. For the multicast transmission mode, as shown in fig. 5, UE1, UE2, UE3 and UE4 form a communication group, where UE1 is a terminal device of a transmitting end and is used for transmitting data, and UE2, UE3 and UE4 in the group are all terminal devices of a receiving end and are used for receiving data. For the broadcast transmission mode, the receiving end may be any one of terminal devices, as shown in fig. 6, where UE1 is a terminal device of a transmitting end, and is used for transmitting data, and other terminal devices around UE1, such as UE2, UE3, UE4, UE5, UE6, and UE7, are all terminal devices of 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 sends side data (including PSCCH and PSSCH) to a terminal device at a receiving end, and the terminal device at the receiving end sends feedback information, such as hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) feedback information, to the terminal device at the transmitting end; and the terminal equipment of the transmitting end judges whether data retransmission is needed according to the feedback information of the terminal equipment of the receiving end. Wherein the HARQ feedback information is carried in a sidestream feedback channel, e.g. a physical sidestream feedback channel (Physical Sidelink Feedback Channel, PSFCH).
In some embodiments, sidestream feedback may be activated or deactivated by pre-configuration information or network configuration information. And if the sidestream feedback is activated, the terminal equipment of the receiving end receives sidestream data sent by the terminal equipment of the sending end, and feeds back HARQ Acknowledgement (ACK)/Negative Acknowledgement (NACK) to the terminal equipment of the sending end according to the detection result. And the terminal equipment of the transmitting end transmits retransmission data or new data according to the feedback information of the terminal equipment of 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 transmitting end generally adopts a blind transmission mode to send data. For example, instead of deciding whether retransmission data needs to be transmitted according to feedback information of the terminal device of the receiving end, the terminal device of the transmitting end repeatedly transmits K times for each sidestream data.
In the case that the terminal device at the transmitting end transmits data in a blind transmission manner, for example, in a broadcast manner or in a unicast manner, and the sidestream feedback is deactivated, the resource selection window can be determined by using the determination manner of the resource selection window in the prior art; the end position of the resource selection window in the time domain as determined should meet the time delay requirement of the service. However, if the sidestream feedback is activated, if the resource selection window is determined by using the determination method of the resource selection window in the prior art, the situation that the retransmission resource cannot be selected when the terminal device at the transmitting end receives the feedback information may result. For example, 100ms when the time delay of the service is required, the maximum value of the determined resource selection window is (n+100) ms when the terminal device at the transmitting end transmits the service for the first time at the time n, if the transmission resource of the first time transmission service is (n+90) 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 the retransmission resource of the terminal equipment at the transmitting end can only be between [ n+97, n+100] ms. If the processing of the terminal device is delayed by 4ms, in this case there is no resource available for retransmission.
Based on the above-mentioned problems, the embodiment of the present application provides a method for determining a resource selection window, which can be applied to various communication systems, for example: global system for mobile communications (Global System of Mobile communication, GSM), code division multiple access (Code Division Multiple Access, CDMA), wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) systems, general packet radio service (General Packet Radio Service, GPRS), long term evolution (Long Term Evolution, LTE) systems, LTE frequency division duplex (Frequency Division Duplex, FDD) systems, LTE time division duplex (Time Division Duplex, TDD), universal mobile telecommunications system (Universal Mobile Telecommunication System, UMTS), worldwide interoperability for microwave access (Worldwide Interoperability for Microwave Access, wiMAX) communication systems, or 5G systems, and the like.
An optional process flow of the method for determining a resource selection window by using an application provided in the embodiment of the present application, as shown in fig. 8, includes the following steps:
step S101, a terminal device determines a resource selection window according to service attributes, wherein the resource selection window is used for the terminal device to select side uplink transmission resources.
In some embodiments, the traffic attributes include at least one of a number of transmissions and a quality of service (Quality of Service, qoS) of the traffic. Wherein, the QoS may include at least one of service priority, service reliability and service delay; of course, qoS may also include other parameters that characterize quality of service in addition to traffic priority, traffic reliability, and traffic latency. The number of service transmissions may be a maximum number of transmissions of the service; the service transmission times can also be preconfigured transmission times or network configured transmission times, for example, the transmission times information is included in the resource pool configuration information and is used for indicating the maximum transmission times of PSSCH transmitted in the resource pool; the number of traffic transmissions may also be the remaining number of transmissions of traffic. The remaining transmission times of the service are as follows: the difference between the maximum number of transmissions of the service and the number of times the service 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 alternative embodiment, the terminal device allocates the size of the resource selection window equally in the time delay requirement range of the service according to the transmission times of the service. For example, the delay requirement of the service is 100ms, the transmission time of the service is 4 times, and the size of each resource selection window is 100ms/4 times=25 ms.
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, a value obtained by rounding the ratio of the time delay requirement of the service to the transmission times of the service. It can be understood that, when the ratio of the time delay requirement of the service to the transmission frequency of the service is an integer, 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. 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: a value obtained by rounding the ratio of the time delay requirement of the service to the transmission times of the service; the rounding operation may be an up rounding operation or a down rounding operation.
For example, the delay requirement of the service is 100ms, the number of transmissions of the service is 4, an alternative schematic diagram of the resource selection window is shown in fig. 9, where the end position of the first resource selection window on the time domain resource is (n+25) ms, the end position of the second resource selection window on the time domain resource is (n+50) ms, the end position of the third resource selection window on the time domain resource is (n+75) ms, and the end position of the fourth resource selection window on the time domain resource is (n+100) ms. For another example, the time delay requirement of the service is 100ms, the number of times of transmission of the service 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 manner, the terminal device allocates the size of the resource selection window exponentially in the time delay requirement range of the service according to the transmission times of the service. When the terminal equipment performs data transmission, the reliability of initial transmission is higher and even reaches about 90 percent; therefore, the probability of data retransmission is very low, for example, about 10% of services need to perform data retransmission. To ensure that there are enough side-link transmission resources available for selection in the initial transmission, and to reduce the probability of collisions of side-link transmission resources, the end position of each resource selection window in the time domain may be configured in an exponentially proportional manner.
In a specific implementation, the end position of each resource selection window on the time domain resource may be a ratio of the time delay requirement of the service to the first function; or, a value obtained by rounding the ratio of the delay requirement of the service to the first function. Optionally, the first function comprises 2 k K is the kth transmission of the service, and k is a positive integer. For example, the time delay of the service is 100ms, the transmission time of the service is 4 times, and the end position of each resource selection window on the time domain resource is 100-100/2 k K=1, 2,3; when k=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 transmission times of the service is K, the ending position of the previous (K-1) time resource selection window in the time domain is determined; and the final position of the resource selection window corresponding to the last service transmission in the time domain is the time corresponding to the time delay requirement of the service. In particular, the method comprises the steps of,as shown in fig. 10, if the terminal device performs resource selection of the first resource transmission at time n and the maximum transmission number is 4, 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 yet another alternative embodiment, the determining, by the terminal device, a resource selection window according to a 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 associated with the service attribute.
In the case that the first configuration information includes end position information of the resource selection window related to the service priority, that is, in the case that the terminal device 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 device 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 the implementation, if the service attribute is service priority, for the service with high service priority, a resource selection window with an early end position in the time domain can be selected, and an earlier transmission resource can be selected for the service, so that the service can be sent to the terminal equipment of the receiving end as early as possible. Accordingly, for a service with a low service priority, a resource selection window with a late end position in the time domain may be selected.
In the case that the first configuration information includes end position information of the resource selection window related to the service reliability, that is, in the case that the terminal device 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 device 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 the specific implementation, if the service attribute is service reliability, the service reliability can be improved through multiple transmissions of the service, so that for the service with high service reliability, a resource selection window with an early ending position in the time domain can be selected, thereby ensuring that the service has more retransmission opportunities and improving the service reliability. For traffic with low traffic reliability, a resource selection window with a late end 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, under the condition that 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 the implementation, if the service attribute is service delay, different end positions of the resource selection window can be configured for different service delays, and for the service with low service delay, the resource selection window with an early end position in the time domain can be selected, so that an earlier transmission resource is selected for the service, and the service can be sent to the terminal equipment of the receiving end as early as possible. For services with high service delay, a resource selection window with a late end 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 the network device.
The method for determining the resource selection window can ensure that the method can have selectable side uplink transmission resources when each service transmission (including first transmission and retransmission) is carried out. And, by configuring different end positions of the resource selection window in the time domain for services with different service attributes, the requirements of the services, such as the transmission times requirement of the services and/or the QoS requirement of the services, can be satisfied.
