Abstract: The invention relates to an improved transmission protocol for uplink data packet transmission in a communication system. A receiver of a user equipment receives a Fast Retransmission Indicator, referred to as FRI. The FRI indicates whether or not a base station requests a retransmission of a previously transmitted data packet. A transmitter of the user equipment retransmits the data packet using the same redundancy version as already used for the previous transmission of the data packet.

Abstract: Provided are an eNB, a UE and wireless communication methods. The eNB, in an embodiment, includes circuitry operative to fill a SPS activation/deactivation field in a DCI with a predetermined pattern of bits; and a transmitter operative to transmit the DCI to a first UE for the first UE to start periodically transmitting signals to a second UE or stop periodically transmitting signals to the second UE based on the SPS activation/deactivation field. The DCI is in a SPS format formed by adopting part or all bits of at least one field of DCI format 5 as the SPS activation/deactivation field, and information supposed to be transmitted in the at least one field is indicated with the assistance of or by RRC or MAC signaling.

Abstract: A terminal is disclosed, which is capable of appropriately determining a resource to which a DCI is mapped. A DCI receiver (203) receives first and second downlink (DL) control signals, and a signal demultiplexer (202) demultiplexes a DL data signal from a received signal, using the first and the second DL control signals. The DCI receiver (203) identifies a resource for the second DL control signal based on information on the first DL control signal, or information on the DL data signal, indicated by the first DL control signal.

Abstract: A communication apparatus includes circuitry that determines a number of resource blocks forming a resource block group, which is a unit used to allocate a resource to the communication apparatus, in a first band or in a second band that is an expanded band to which the first band is expanded, and a subcarrier spacing for the second band is same or different from a subcarrier spacing for the first band; and a transceiver that is coupled to the circuitry and that communicates with a base station using the resource. One of the number of resource blocks set for the first band and the number of resource blocks set for the second band is an integer multiple of the other, and the number of resource blocks set for the first band and the number of resource blocks set for the second band are values that are a power of two.

Abstract: Provided are wireless communication methods and devices. In one embodiment, a wireless communication method performed by a wireless communication device comprises: transmitting a data packet repeatedly in multiple subframes including at least one normal subframe and at least one special subframe to another wireless communication device, wherein the available resources in the special subframe are different from that in the normal subframe, the data packet includes multiple modulated symbols which are divided into multiple modulated-symbol sets, in each subframe, each OFDM symbol is mapped by one of the modulated-symbol sets, and in every subframe, the modulated symbols in the same modulated-symbol set are mapped onto REs in one OFDM symbol in a fixed order. In another embodiment, multiple repetitions of the data packet are transmitted in each subframe, and in each special subframe, different repetitions are mapped onto REs with cyclic shift.
