TECHNIQUES FOR FLEXIBLE DUPLEXING

WIPO Patent Application WO/2017/020289

A1

The present disclosure, for example, generally relates to wireless communication systems, and more particularly to techniques for flexible duplexing in such systems. For example, a technique for flexible duplexing provides a reference configuration that determines characteristics for paired frequency division duplexing (FDD) bands when the uplink band is temporarily reconfigured for time division duplexing (TDD) use. A user equipment (UE) may use the reference configuration to determine hybrid automatic repeat request (HARQ) timing, schedule uplink transmissions, manage a soft buffer, and determine signaling formats. In an aspect, the UE may receive a reconfiguration message indicating a change for an FDD uplink band to a temporary TDD band. The UE may then determine a reference configuration for a pair of FDD bands including an FDD downlink band and the temporary TDD band, the reference configuration indicating a pattern of sub-frames associated with the pair of FDD bands.
