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.
摘要翻译：为了找到D2D信道，例如用于从分配的D2D信道的卸载业务的共享信道，蜂窝网络接入节点向D2D设备发送具有参数（例如，感测时间，频带，感测机制，循环移位）的配置消息感光谱。根据该频谱感测的结果，决定是否利用根据参数感测到的D2D通信的频带。在一个实施例中，网络选择子帧配置来设置感测时间，其中不同的子帧配置具有作为感测时间的不同长度的保护周期。在实施例中，第一感测在保护周期内并且表示粗略感测结果，并且如果这些感测结果不够，则网络配置更长的感测时间（例如，跨越多个子帧）以获得更精细的感测结果。网络或备选地，D2D设备决定是否使用所感测的频带来进行卸载业务。

摘要： There is transmitted to a user equipment UE in a first subframe of a radio frame a downlink shared channel DSCH according to a first relay-transmission mode (e.g., mode A or A' in the examples); then switch to a second relay-transmission mode (e.g., mode C or C' in the examples) within the radio frame based on a channel quality of the DSCH. After switching, then transmit to the UE, in a subsequent subframe of the radio frame, the DSCH according to the second relay-transmission mode. In this embodiment the HARQ process is synchronous and non-adaptive for mode C: the eNB re-transmits packets to the UE in a predetermined fashion to be concurrent with transmission of those same packets from the relay node, as scheduled by the eNB. In this embodiment the eNB receives the UE's NACK for the data that is to be retransmitted via relay through the relay node.
摘要翻译：根据第一中继传输模式（例如，示例中的模式A或A'），向无线电帧的第一子帧中的用户设备UE发送下行链路共享信道DSCH; 然后基于DSCH的信道质量切换到无线帧内的第二中继传输模式（例如，示例中的模式C或C'）。在切换之后，然后根据第二中继传输模式在无线电帧的后续子帧中向UE发送DSCH。在该实施例中，对于模式C，HARQ进程是同步的和非自适应的：eNB按照预定的方式将数据包重新发送到UE，与eNB的调度从中继节点传输那些相同的分组并发。在本实施例中，eNB通过中继节点通过中继节点接收要发送的数据的UE的NACK。
