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： A network sends data blocks in a first/n1h radio frame having a first configuration of uplink to downlink transmission time intervals TTIs. Each of these data blocks originate a separate hybrid automatic repeat request HARQ process. The network then frequency or spatially mutliplexes first re-transmissions of at least two of the data blocks in at least one TTI of a sequentially next second/(n+1)st radio frame having a different second configuration of uplink to downlink TTIs. If necessary second re-transmissions of the HARQ processes can also be similarly multiplexed in a TTI of a third/(n+2)nd radio frame sequentially next after the second/(n+1)st frame. In the examples, if frequency domain multiplexing the frequency mutliplexed first re-transmissions are separately scheduled; or if spatial domain multiplexing the spatially mutliplexed first re-transmissions are scheduled with a single physical downlink control channel PDCCH.

摘要： A user's downlink component carriers DL-CCs are divided into groups. An aperiodic CQI/PMI report is triggered by signaling (for example one bit). There is a pattern that maps the signaled trigger to a particular DL-CC within a group of DL-CCs that are configured for a user equipment UE, and that mapped particular DL-CC is determined to be the subject of the aperiodic report. In various embodiments the pattern is implicit and points to the DL-CC for which an aperiodic report has not been sent for more than a threshold time interval; or to the DL-CC for which resources have not been allocated for a periodic report; or to every DL-CC in the group that are activated for the user equipment. Examples are detailed for apparatus, method and computer program from the perspective of the network and from the perspective of the UE.
