摘要： User Equipment (UE) mobility in Ultra Dense Networks (UDNs) is based on communication signal layers, which could include respective data streams in an Orthogonal Frequency Division Multiplexing (OFDM) domain, a code domain using respective codebooks, and/or a spatial domain, for example. A UE uses candidate layer decoding parameters in applying layer-based decoding to communication signals that it received from network nodes. Layers could be allocated to UEs and transition between network nodes as UEs move between different network service areas. Layers could instead be allocated to network nodes. Layer-based decoding provides for UE mobility without requiring explicit handover processing every time a UE moves between different service areas.

摘要： A master user equipment (UE) device may coordinate device-to-device (D2D) communications amongst a plurality of UE devices. For example, a UE device, which has been designated as a master UE device, may coordinate a D2D communication between a first UE device and a second UE device. The master UE device may be a UE device that obtains an indication that it is a master UE device that is to coordinate D2D communications amongst the plurality of UE devices. In some embodiments, the coordinating the D2D communication may be on behalf of a network and/or to facilitate wireless communication between the network and at least one of the plurality of UE devices.

摘要： A method of simultaneous bidirectional transmissions, the method comprising determining, by a network element, first transmission time slots for downlink and uplink transmissions for a first plurality of user equipment (UEs); assigning a DL transmission to a first shared time slot of the first transmission time slots for a first UE in the first plurality of UEs; and assigning an UL transmission to the first shared time slot for a second UE in the first plurality of UEs, wherein the first and second UEs form a virtual UE to communicate in virtual full duplex in at least the first shared time slot.
