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： There is provided a mechanism for conducting power control in a time division based communication. Subframes of a frame structure of the time division based communication are classified into at two or more classification sets, each classification set comprising at least one subframe. For each of the classification sets, power control related parameters are selected in accordance with the interference on the respective subframes. On the basis of the selected power control related parameters, a power control parameter set is configured defining a power control setting for each subframe of the frame structure. A UE receiving the power control parameter set applies the power control related parameters in the power control.
