Methods and apparatus for determining device-to-device transmission patterns
Abstract
Embodiments include methods and apparatuses for the design, construction and selection of base patterns and associated control signaling for direct device-to-device (D2D) communication, independent of a network. An embodiment includes the selection and transmission, by a wireless transmit and receive unit (WTRU), of base patterns in a scheduling period when the number of medium access control (MAC) protocol data units (PDUs) is larger than the number of MAC PDUs that a family of pre-determined base patterns can support. An embodiment may include the selection and transmission, by a WTRU, of base patterns in a scheduling period when the number of MAC PDUs is smaller than the number of MAC PDUs that a family of pre-determined base patterns can support. In addition, embodiments may include the selection, by a WTRU, of a base pattern or base patterns to minimize interference with other communications and to use resources efficiently.
