摘要： A WTRU may receive downlink control information (DCI) indicating a start of a frame. The DCI may be received on a control channel, such as the Physical Downlink Control Channel (PDCCH) from an eNB, base station, AP, or other infrastructure equipment operating in a wireless communications system. The WTRU may decode the DCI and may determine a transmit time interval (TTI) duration, which may be expressed in terms of an integer number of basic time intervals (BTIs). The WTRU may determine a downlink (DL) transmission portion and assignment and an uplink (UL) transmission portion and UL grant based on the received DCI. Additionally, the WTRU may determine the start of the UL portion based on an offset (toffset). The WTRU may receive data in a DL portion of the frame and may transmit in an UL portion of the frame based on the determined UL grant and TTI duration.

摘要： Techniques and devices are disclosed for efficient offloading and/or aggregation of resources by providing different levels of connection management in a network. A wireless transmit/receive unit (WTRU) may support additional ECM and/or RRC states (e.g. inactive states) and/or transitions that may enable a WTRU to act without an RRC connection and/or with reduced latency. A WTRU may operate with network resources with and/or without radio resources. A WTRU may operate in parallel with a plurality of layers, including a primary layer for which the WTRU may behave according to LTE or other behavior. The WTRU may be configured for operation in a secondary layer. The WTRU may establish a secondary layer security context and/or a tunnel or routing for the secondary layer for transport of user plane data between the WTRU and a gateway. The WTRU may determine to which layer uplink data may be applicable.

摘要： A WTRU may determine that a LTE cell at least partially overlaps in frequency with an NR cell. The WTRU may determine that an NR transmission is to be received within a set of resources that are included in at least a portion of the NR cell that at least partially overlaps with the LTE cell. The WTRU may determine a subset of resources within the set of resources that correspond to an LTE common transmission. The WTRU may receive the NR transmission within the set of resources. The NR transmission may not be included in the subset of resources that correspond to the LTE common transmission. The LTE common transmission may include one or more of a common control signal, a cell-specific broadcast signal, cell-specific reference signals, a physical downlink control channel, a primary synchronization signal, a secondary synchronization signal, and/or a channel state information reference signal.

摘要： Systems, methods, and instrumentalities may be disclosed for implementing a flexible radio access communication system. A flexible radio access communication system may be supported using spectrum of varying size, including aggregation of non-adjacent carriers in the same and/or in different frequency bands. A wireless transmit/receive unit (WTRU) may receive a first transmission via a common downlink control channel. The first transmission may include first control information. The first control information may include information regarding the configuration of a first dedicated downlink control channel of one or more dedicated control channels. The WTRU may receive a second transmission via the first dedicated downlink control channel of the dedicated control channels. The second transmission may include second control information. The second control information may be associated with a transmission of a first transmission type. The dedicated downlink control channels may be used for providing control information associated with different types of transmissions.

摘要： Systems, methods and instrumentalities may be provided for handling a user plane in a wireless communication system. The wireless communication system may be characterized by a flexible air interface. One aspect of the flexible air interface is that transmissions by a wireless transmit/receive unit (WTRU) in the system may have different quality of service (QoS) requirements, such as different latency requirements. The WTRU may adjust its behaviors based on the QoS requirements, e.g., by utilizing preconfigured resources, resource requests, self-scheduling, and/or the like, such that the transmissions may be performed in accordance with their respective QoS requirements.
