Abstract: In one aspect, resource selection may be performed where single frequency full-duplex (SFFD) UEs are present in a V2X system. Signaling and procedures may enable the coexistence of half-duplex (HD) and SFFD-capable UEs. Based on the resource reservation information obtained from other UEs, the SFFD UE may determine which among the reserved time-frequency resources is amenable for performing the SFFD operation. In one aspect, the time-frequency resources chosen for SFFD may partially or fully overlap with the reserved time-frequency resources, based on the self-interference cancellation capability of the SFFD UE, the RSRP, and/or the RSSI on the reserved time-frequency resources. Accordingly, the full-duplex capability of an SFFD-capable UE may be leveraged, and spectral efficiency improved.
