    摘要: To find a D2D channel, by example a shared channel for offload traffic from an allocated D2D channel, a cellular network access node sends a configuration message with parameters (e.g., sensing time, frequency band, sensing mechanism, cyclic shift) for a D2D device to sense spectrum. From results of this spectrum sensing is decided whether to utilize a frequency band, sensed according to the parameters, for D2D communications. In an embodiment the network selects a subframe configuration to set the sensing time, in which different subframe configurations have different-length guard periods which is the sensing time. In embodiments a first sensing is within a guard period and represents coarse sensing results and if those are not sufficient the network configures a longer sensing time (e.g., spanning multiple subframes) for finer sensing results. The network or alternatively the D2D device decides whether to use the sensed frequency band for offload traffic.

    摘要: Device-to-device (D2D) communication is one alternative to communication between devices through a radio access network. One interesting D2D communication method is reuse-mode D2D, where D2D nodes communicate with each other using the same uplink (UL) radio resource that is being used by some other cellular user equipment(s) (UEs). In other words, the UL cellular resources occupied by cellular UEs are reused by D2D nodes in their short-range communications. Centralized control of D2D communication can be performed by appropriate signaling between a D2D-capable UE and an evolved Node B (eNB).

    摘要: A method is provided for facilitating multicast service. The method may include receiving data multicast to members of a multicast group. The method may further include determining, based at least in part on an indication received during multicast of the data, that a late joining device has joined the multicast group subsequent to initiation of the multicast. The method may additionally include marking, based at least in part on the received indication, a point at which the late joining device began to participate in the multicast. A corresponding apparatus and computer program product are also provided.
