Abstract: The present disclosure provides a scheduling assignment indicating method and device-to-device (D2D)-enabled wireless device. The method is used by D2D-enabled wireless devices communicating with each other via multiple SA periods, each of which including a SA pool and a data pool, wherein the SA pool is used for transmitting SA for assigning data resource of the data pools, the method comprising: selecting SA resources in SA pools of more SA periods to transmit SA to assign the same data resource for the D2D-enabled wireless device. The SA indicating method and D2D-enabled wireless device according to the present disclosure can increase the capacity of the SA pools, avoid SA and/or data transmission collisions, and increase the robustness of the SA transmission.

Abstract: An integrated circuit includes reception circuitry and demodulation circuitry. The reception circuitry, in operation, controls receiving one or more repetitions of control information in a search space region. The search space region includes a first plurality of sub-regions of different lengths for a largest repetition number of the control information. The search space region includes a second plurality of sub-regions of different lengths for a second-largest repetition number of the control information. An interval of subframes to which the first plurality of sub-regions are mapped is greater than an interval of subframes to which the second plurality of sub-regions are mapped. The demodulation circuitry, in operation, controls performing a demodulation process of the one or more repetitions of the control information.

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.

Abstract: Provided are wireless communication methods, a UE and an eNB. The wireless communication method performed by a UE includes transmitting transport block repetitions to an eNB, wherein one HARQ process includes multiple repetition sets of a transport block if one repetition set of the transport block is not enough for the eNB to successfully decode the transport block, each of the multiple repetition sets includes multiple repetitions of the transport block, each of the multiple repetition sets is followed by a feedback channel to indicate whether the transport block is successfully decoded by the eNB.

Abstract: A wireless communication method includes receiving a reference signal and a data signal, based on a coverage enhancement level represented by a number of transmission repetitions; processing the reference signal and the data signal received by the receiving; setting a number of resource elements for transmitting the reference signal based at least on a channel type; and setting usage of resource elements indicated by a System Information Block (SIB). The reference signal is a Cell-specific Reference Signal (CRS) or a Demodulation Reference Signal (DMRS).

Abstract: The present disclosure provides a band usage information generating and reporting method, a charging method, an eNB, a CN, a MME and a UE. The eNB and the UE can generate band usage information for charging, and report the band usage information to the CN, wherein the band usage information involves band usage of at least a first band and a second band, and traffic is assigned to respective bands by the eNB. The Counting entity at the eNB or UE can count the data volume of each band or ratio of data volume via different bands as the band usage information based on the scheduling information of the data. The Charging system located in the CN can process the charging and generate a bill according to the reported band usage information.
