摘要： Systems, methods, and instrumentalities are disclosed for downlink resource allocation associated with a shared frequency band. A WTRU may receive resource allocation information associated with a component carrier and at least one carrier segment. The component carrier and the least one carrier segment may each comprise a plurality of resource block groups (RBG). At least two bitmaps may be associated with the resource allocation information. A size of a resource block group (RBG) of the component carrier and the at least one carrier segment may be based on a combined number of resource blocks (RB) of the component carrier and the one or more carrier segments divided by a 3GPP Rel-8/Rel-10 RBG size of the component carrier. The WTRU may determine at least one RBG allocated to the WTRU using the resource allocation information and may receive and decode the at least one RBG allocated to the WTRU.

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： Systems and methods are contemplated for reconfiguration of one or more MAC instances while the WTRU is operating using dual- or multi-MAC instance connectivity. For example, upon reception of RRC reconfiguration information that modifies one or more secondary MAC instances, the WTRU may transmit a reconfiguration complete message to a Macro eNB (MeNB) and may synchronize to small-cell or secondary eNB (SeNB), for example if triggered by one or more of an RRC flag, a physical downlink control channel (PDCCH) order (MeNB/SeNB), MAC activation information, etc. For example, the WTRU may synchronize to the SeNB for specific type(s) of RRC reconfigurations, but not other type(s) of RRC reconfigurations. Although examples may be described in terms of dual connectivity, the WTRU may establish connectivity and perform mobility procedures with more than two radio access network (RAN) nodes (e.g., eNBs), and the embodiments described may be equally applicable to those scenarios.
摘要翻译：在WTRU使用双MAC或多MAC实例连接操作的同时，考虑了一种或多种MAC实例的重新配置的系统和方法。例如，在接收到修改一个或多个辅助MAC实例的RRC重新配置信息时，WTRU可以向宏eNB（MeNB）发送重新配置完成消息，并且可以与小小区或辅助eNB（SeNB）同步，例如，由RRC标志，物理下行链路控制信道（PDCCH）顺序（MeNB / SeNB），MAC激活信息等中的一个或多个触发。例如，WTRU可以与针对特定类型的RRC重新配置的SeNB同步，而不是其他类型的RRC重新配置。尽管可以以双重连接来描述示例，但是WTRU可以利用多于两个的无线接入网（RAN）节点（例如，eNB）建立连接并执行移动性过程，并且所描述的实施例可以同样适用于这些场景。

摘要： Systems, methods, and instrumentalities are provided to implement scheduling for device-to-device (D2D). A WTRU (e.g., a D2D WTRU) may determine whether the WTRU has D2D data to transmit. The WTRU may determine a set of allowed SA resources and/or allowed D2D data resources for transmission of the SA. The WTRU may select an SA resource and/or D2D data resources (e.g., from the set of allowed SA resources and/or D2D data resources) for transmission. The WTRU may select one or more transmission parameters. The WTRU may select one or more transmission patterns. The WTRU may transmit D2D data over the set of allowed D2D resources using the selected transmission patterns and according to the selected transmission parameters.

摘要： Physical layer processing and procedures for device-to-device (D2D) discovery signal generation and transmission and scheduling of D2D discovery signals are described. Detection and measurement of a D2D discovery signal, D2D signal identity management, and monitoring by a wireless transmit/receive unit (WTRU) of PDCCH for D2D discovery scheduling is described, as is a WTRU that may be configured with a D2D-specific transmission/reception opportunity pattern. The discovery signal may carry a payload for explicit information about user and/or service identity, and may be mapped to physical resources in such a way as to decouple transmission/reception of the discovery signal from downlink operations. A WTRU may measure a D2D discovery signal quality and report to the network.
