Abstract
Half duplex (HD) frequency division duplexing (FDD) in a wireless transmit-receive unit (WTRU) using a single oscillator (SO) for uplink (UL) and downlink (DL), which may contribute to reduced costs of implementation. Approaches to the resolution of scheduling issues which may result from increased switching time versus implementations using separate oscillators are discussed, including indication of SO-HD-FDD capability, scheduling for collision avoidance, enhanced node-b (eNB) receiver implementations, link adaptation for missed detected physical downlink control and shared channels, collision handling, DL measurement, and burst based transmissions.
