Embodiment 1
[0067] Embodiment 1 illustrates the processing flow chart of the first node of an embodiment of the present application, as shown in the appendix. figure 1 shown. in the attached figure 1 , each box represents a step.
[0068] In Embodiment 1, the first node in this application first executes step 101 to receive the first signaling; executes step 102 to execute the first channel sensing in the first resource pool; and then executes step 103 to determine the target resource pool; Then step 104 is performed to select a target time-frequency resource block from the target resource pool; finally step 105 is performed to send a second signaling on the target time-frequency resource block; the first signaling indicates the first reference resource set, the The first reference resource set includes at least one time-frequency resource block; the first channel sensing is used to determine the target resource pool; the first candidate time-frequency resource block is a time-frequency...
Embodiment 2
[0242] Embodiment 2 illustrates a schematic diagram of a network architecture according to the present application, as shown in the accompanying figure 2 shown. attached figure 2 A diagram illustrating the network architecture 200 of the 5G NR, LTE (Long-Term Evolution) and LTE-A (Long-Term Evolution Advanced) systems. The 5G NR or LTE network architecture 200 may be referred to as 5GS (5G System) / EPS (Evolved Packet System) 200 in some other suitable term. The 5GS / EPS 200 may include one or more UE (User Equipment, user equipment) 201, a UE 241 that performs sidelink (Sidelink) communication with the UE 201, NG-RAN (Next Generation Radio Access Network) 202, 5GC (5G Core Network, 5G core network) / EPC (Evolved Packet Core, evolved packet core) 210, HSS (Home Subscriber Server, home subscriber server) / UDM (Unified Data Management, unified data management) 220 and Internet service 230. 5GS / The EPS may interconnect with other access networks, but these entities / interfaces a...
Embodiment 3
[0256] Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture of a user plane and a control plane according to the present application, as shown in the accompanying drawings. image 3 shown. image 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300, image 3 Present with three layers for the first node device (RSU in UE or V2X, in-vehicle device or in-vehicle communication module) and the second node device (gNB, RSU in UE or V2X, in-vehicle device or in-vehicle communication module), or Radio protocol architecture of the control plane 300 between two UEs: Layer 1, Layer 2 and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical Layer) signal processing functions. The L1 layer will be referred to herein as PHY301. Layer 2 (L2 layer) 305 is above the PHY 301 and is responsible for the link between the first node device and the s...
