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: Provided are a user equipment, base station and wireless communication methods related to resource determination for UCI in case of BWP switching in NR. A user equipment comprises: a receiver operative to receive, from a base station in a slot, a Downlink Control Information (DCI) for Bandwidth Part (BWP) switching from a first BWP to a second BWP; circuitry operative to drop a Uplink Control Information (UCI) to be transmitted in a BWP switching period of the first BWP, and to determine the earliest available slot of the second BWP or a third BWP, the BWP switching period being from the slot where the DCI for BWP switching is received until starting the second BWP to which the first BWP is switched according to the DCI; and a transmitter operative to transmit the dropped UCI in the determined earliest available slot of the second BWP or the third BWP to the base station.

Abstract: The present disclosure provides a method of setting reserved subframes for indication of a resource pool by a bitmap, a user equipment, and a base station. In the present disclosure, the resource pool is used for transmitting or receiving sidelink signals within a system frame number cycle that includes predefined subframes and remaining subframes that are subframes after excluding the predefined subframes within the system frame number cycle. In the method, a number of the reserved subframes is determined so that the bitmap is repeated by integer times within the subframes after excluding the reserved subframes and the predefined subframes within the system frame number cycle. In the method, position of each of the reserved subframes is set, wherein at most two reserved subframes are set per n subframes within the system frame number cycle.

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: 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.
