  • Patent number: 8953467
    Abstract: 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.

  • Patent number: 8849290
    Abstract: The specification and drawings present a method, apparatus and software related product (e.g., a computer readable memory) for improving device discovery and D2D operation, e.g., in LTE wireless systems, by using control signaling provided by a wireless network (e.g., by an eNB). The discovery channel/channels which conveys discovery signal/signals are configured by a network (e.g., by the eNB) and are mapped to control channel/channels (e.g., one-to-one). After sending/receiving the discovery signal/signals, the D2D devices are monitoring control channel/channels to get current information for establishing the D2D communication among these D2D devices, the current information may include a resource allocation for the D2D communication and a device list of candidates for establishing the D2D communication.
