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： The present invention discloses a cluster head assisted method for converting a user terminal from device-to-device (D2D) communication to cellular communication. When quality of a D2D link between a user terminal and a cluster head is lower than a predetermined threshold, if the user terminal has to leave the cluster but still expects to continue an original the service, the user terminal performs cell search and random access, and establishes a radio resource control (RRC) connection with a target base station of a cellular network. Switching from D2D communication to cellular communication is implemented with the assistance of the cluster head, and a communication manner after the switching is provided. The present invention implements mobile switching from D2D communication in distributed cluster communication to cellular communication, which can reduce route search delay and save wireless resources.

摘要： A multicarrier data transmission scheme is provided. According to the provided scheme, a radio transmitter encodes data bits with different degrees, the degree of an encoded data bit being defined by the number of parity check equations protecting the data bit. The data bits are preferably encoded with an irregular low-density parity check (LDPC) code. The encoded data bits are then mapped to symbols. The symbols are allocated to subcarriers of a multicarrier radio signal on the basis of channel state information obtained from the radio receiver and the degree used with respect to each symbol. On the basis of the channel state information, a number of subcarriers are truncated due to high attenuation, and the number of subcarriers to be truncated relative to the total number of subcarriers is substantially fixed. The available transmit power to the non-truncated subcarriers. The multicarrier signal comprising symbols on the non-truncated subcarriers is then transmitted to the radio receiver.
