Definitions
- This application belongs to the field of communications, and specifically relates to an information sending method, resource processing method, device, and electronic equipment.
- LTE Long Term Evolution
- LTE sidelink is based on broadcasting for communication. Although it can be used to support the basic security communication of vehicle to everything (V2X), it is not suitable for other more advanced V2X services.
- the 5G NR (New Radio) system will support more advanced sidelink transmission design, such as unicast, multicast or multicast, etc., so as to support more comprehensive service types.
- NR V2X defines two resource allocation modes, one is mode 1, which schedules resources for the base station; the other is mode 2, where the terminal decides what resources to use for transmission.
- the resource information may come from a broadcast message of the base station or pre-configured information. If the terminal works within the range of the base station and has a radio resource control (RRC) connection with the base station, it can be mode 1 and / mode 2. If the terminal works within the range of the base station but does not have an RRC connection with the base station, it can only work In mode 2; if the terminal is outside the range of the base station, it can only work in mode 2, and perform V2X transmission according to the pre-configured information.
- RRC radio resource control
- the specific working methods are as follows: 1) After the resource selection is triggered, the transmitting terminal first determines the resource selection window. The lower boundary of the resource selection window is at time T1 after the resource selection is triggered, and the upper boundary of resource selection is after the trigger. T2 time, where T2 is the value selected in the data delay (Packet Delay Budget, PDB) of its transport block (Transport Block, TB) implemented by the terminal, and T2 is not earlier than T1. 2) The terminal selects resources in the terminal. Before, the candidate resource set for resource selection (candidate resource set) needs to be determined, and the reference signal received power (RSRP) measured on the resources in the resource selection window is compared with the corresponding RSRP threshold. If RSRP Below the RSRP threshold, the resource can be included in the set of candidate resources. 3) After the resource set is determined, the terminal randomly selects transmission resources from the candidate resource set. In addition, the terminal can reserve transmission resources for the next transmission in this transmission.
- PDB Packet Delay Budget
- T2 the value
