Problems solved by technology

However, sensing is performed at the transmitter rather than the receiver, leading to the well-known hidden terminal problem
Furthermore, the resource selection process does not take into account the impact of the final transmission on nearby receivers

Abstract

A wireless communication device (UE) supporting multiple sidelink radio resources SRR, suitable for vehicle networking, V2X, intelligent driving or intelligent networked vehicles, the UE measures the first signal strength parameter PSSCHRSRP associated with at least one adjacent UE and / or measure a second signal strength parameter S-RSSI associated with at least one of the above-mentioned plurality of SRRs. The UE determines the interference-related parameter H associated with at least one of the above-mentioned multiple SRRs i es, especially the PSSCH interference margin; calculate the identity-related parameters (ID i ) maps to P ij or a first mapping of a function thereof; and / or computing a mapping of at least one SSR to I i (s) or H j (s) or a second mapping (C) of a function thereof. The UE is used to use the S j and / or C j sent to the base station and / or at least one neighboring UE.

Description

technical field [0001] The present invention relates to wireless communications. More specifically, the present invention relates to a wireless communication device and method for communicating in a communication network, especially a vehicle-to-vehicle (V2V) communication network. Background technique [0002] The 3rd Generation Partnership Project (the 3 rd The generation partnership project (3GPP) is enhancing the long term evolution (LTE) specifications towards 5G to support vehicle-to-everything (V2X) services. [0003] In V2V, or more generally, in a V2X communication network, information exchange between user equipment (UE) such as vehicles can pass through the base station via the LTE-Uu interface (ie, uplink / downlink) or directly device-to-device (device-to-device, D2D) (ie, sidelink (sidelink, SL)) via the PC5 interface. Direct communication mode is supported when UE is served by E-UTRAN and when UE is out of E-UTRA coverage (see "3GPPTS 36.300, Evolved Universa...
