摘要： Methods and apparatuses are described for cooperation of two or more devices to improve the transmissions over a Uu interface. A source receives or transmits an indicator indicating a first mode of two modes of cooperation between the source apparatus and at least a first cooperating device. The two modes of cooperation includes a joint communication mode and a relay mode of cooperation. If the first mode is the joint communication mode, at least a portion of the data, intended for the intended recipient, is transmitted to at least the first cooperating device to be further transmitted by the first cooperating device to the intended recipient. A same or different portion of the data is transmitted to the intended recipient or to a second cooperating device to be further transmitted by the second cooperating device to the intended recipient.

摘要： A network for facilitating wireless radio communication. The network includes a first access area, wherein the access area includes one or more transmission/receive points. At least one transmission/receive point includes a base station that supports wireless communication between a network and user equipment (UE), such as, a mobile device. The network includes a dedicated connection signature (DCS) that is assigned to a UE. The DCS provides for and is used by the UE to maintain active, unified access to the wireless network. More particularly, the DCS provides for active, contention free, and fast access for the UE to the network through transmission/receive points within the first access area, which is of significance to present and future UE centric virtual radio access networks having high densities of mobile and non-mobile users and with high populations of different types of traffic patterns and applications.
