Definitions
- the second processing unit selects a target resource pool according to the second parameter; selects a resource in the selected target resource pool;
- FIG. 21 is a schematic diagram of another terminal device hardware structure provided by this application.
- FIG. 22 is a schematic diagram of the composition structure of the communication system provided by this application.
- the selecting resources or excluding resources includes: selecting resources or excluding resources from N sets of resources divided by the resource pool; N is an integer greater than or equal to 2.
- the terminal excludes resources based on the RSRP threshold.
- pre-configuration refers to pre-defined or pre-defined.
- the first threshold value and second threshold configuration mode of RSRP includes one of the following methods:
- the resource selected by the vehicle moving in the east-west direction may also fall into the first group of resources. For example, this is because when vehicle C excludes resources based on the RSRP threshold T_low on the first set of resources, it does not find that there are resources with an RSRP value higher than the threshold T_low on the target time slot of the first set of resources, which means Vehicle C does not find that there is a short-distance vehicle in the target time slot that reserves the resources in the time slot. Therefore, at this time, vehicle C can select the resources in the target time slot to send data or signaling, which will not cause strong damage to other vehicles. interference.
- the resources are divided into two groups, and the terminal obtains the distance threshold of each group of resources based on the movement direction as an example.
- the specific process is as follows:
- the direction of movement is divided into two groups.
- the range of the angle between the movement direction and the reference direction (for example, true north) is [-180, 180) degrees
- the movement direction within the range of [135,180] degrees is the first group of movement directions
- the movement direction with the absolute value of the included angle with the reference direction (for example, true north) within the range of (45,135) degrees is the second group of movement directions.
- CBR Channel Busy Ratio
- PPPP ProSe Per-Packet Priority
- the first processing unit 31 is configured to configure or pre-configure the first parameter according to the direction, and select or exclude the resource according to the first parameter;
