摘要： A method can include receiving at a cluster head, a multicast/broadcast packet from a base station. The method can also include monitoring, at the cluster head, to detect whether any members of a cluster of the cluster head responds to the multicast/broadcast packet with a negative acknowledgment directed to the cluster head. The method can further include, when a result of the monitoring is no detection of any negative acknowledgments, and the cluster head successfully received the multicast/broadcast packet, sending, by the cluster head, a general acknowledgment of the multicast/broadcast packet to the base station.

摘要： A method and an apparatus for switching D2D data communications between a licensed and a license-exempt band are disclosed. A D2D device receives from a cellular network a pre-switch notification to prepare for a switch of its D2D communications, and in response adopts a temporary strategy for conducting its D2D transmissions prior to the switch. After the switch the D2D device discontinues the temporary strategy. In one embodiment the temporary strategy and its duration are indicated in the pre-switch notification. Two example temporary strategies are presented: 'no-new-data' where new data transmissions are suspended and data re-transmissions are sent with high reliability; and 'no-feedback' where new data is sent with high reliability and data re-transmissions are suspended. Different embodiments have the cellular network access node or D2D device contending for the radio resource in the license-exempt frequency band.
摘要翻译：公开了一种在许可证和免许可频段之间切换D2D数据通信的方法和装置。 D2D设备从蜂窝网络接收预切换通知以准备其D2D通信的切换，并且响应采用用于在切换之前进行其D2D传输的临时策略。开关后，D2D设备停止临时策略。在一个实施例中，临时策略及其持续时间在切换前通知中指示。提出了两个示例性的临时策略：暂停新数据传输的“新数据”，高可靠性发送数据重传; 和“无反馈”，其中发送新数据的高可靠性和数据重传被暂停。不同的实施例具有蜂窝网络接入节点或D2D设备在免许可频段中竞争无线电资源。

摘要： From a plurality of messages provided by at least a first license-exempt access node which give usage information for the at least one channel in license-exempt radio spectrum, there is derived channel-specific statistical traffic information. This information for the channel is then provided to a second access node that controls licensed radio spectrum. Or in another embodiment the second access node can get this information by sensing and measuring the channel itself. The second access node retrieves this information from its local memory and sends on the licensed radio spectrum a downlink message having contents, determined from the channel-specific statistical traffic information, for aiding a user equipment UE to access the channel with a probability defined by the contents. The UE receives this message, extracts the contents, and attempts to access that channel in the license-exempt radio spectrum utilizing the defined probability.
