Abstract:
Direct communication (radio cross link) between nodes (UEs) in advanced topology (LTE) applications. A method includes a first node (user equipment, UE) receiving a cross link grant specifying resources for use by at least the first node (UE) for transmission on the radio cross link (direct link). The first node also performs cross link scheduling per transmission time interval (TTI) within the resources specified in the cross link grant and transmits at least one packet to a second node (second UE) based on the cross link scheduling grant per TTI. In another embodiment, y wireless transmit/receive unit, WTRU (UE), adapted to discard stalled (stored) RLC protocol data units, PDUs, at a helper (assisting, supplemental) WTRU (UE) on the downlink is disclosed, wherein PDUs stored at a logical channel queue or buffer are discarded (dropped) if a discard time set expires. Additionally, a system is claimed in which pairs of WTRU (UEs) are adapted to negotiate a cross link (direct link) scheduling per transmission time interval, TTI, within the resources specified in a cross link grant.
