Abstract: Two physical layer user terminal capability alternatives are introduced for device-to-device discovery for FDD mode terminals: a full discovery physical layer capability, and a partial discovery physical layer capability. The full discovery physical layer capability corresponds to an alternative where a discovery-capable user terminal has a capability to perform both Discovery_Scan (on an uplink band) and Discovery_Tx (on a downlink band) operations. A Discovery_Tx operation corresponds to transmission of a discovery signal to another user terminal directly over the air. A Discovery_Scan operation corresponds to reception of the discovery signal from another user terminal directly over the air. The partial discovery physical layer capability corresponds to an alternative where the discovery-capable terminal has a capability to perform either Discovery_Scan operation (on the downlink band) or Discovery_Tx (on the uplink band) operation (or both).

Abstract translation: 为FDD模式终端的设备到设备发现引入了两个物理层用户终端功能替代方案：完全发现物理层功能和部分发现物理层功能。 完全发现物理层能力对应于具有发现能力的用户终端具有执行Discovery_Scan（在上行链路频带）和Discovery_Tx（在下行链路频带上）操作的能力的替代方案。 Discovery_Tx操作对应于直接在空中将发现信号发送到另一个用户终端。 Discovery_Scan操作对应于直接在空中接收来自另一个用户终端的发现信号。 部分发现物理层能力对应于可发现能力终端具有执行Discovery_Scan操作（在下行链路频带）或Discovery_Tx（在上行链路频带上）操作（或两者）的能力的替代方案。
