The invention relates to a mapping device of a physical communication channel in an orthogonal frequency-division multiplexing system and a mapping method thereof, wherein the method implements the following steps to each flow of symbols which is generated after a code clock in a transmission block is processed, firstly orderly dividing the flow of symbols into a plurality of resource block transmission units with the resource block transmission length, secondly, determining the mapping area which integrates the resource blocks which are corresponding to the flows of symbols and the quality indicated value of the communication channels which are respectively corresponding to the resource blocks in the area, thirdly, mapping the resource transmission block unit which is near to the front most position of the unmapped position into the resource block whose indicated value of the unmapped communication channel quality is the biggest. The method improves the decrypting accuracy of a terminal and reduces the retransmitting frequency through mapping the RB transmission unit whose position is near to the front position in the flow of signals into the RB with higher CQI value.

A method in which a first apparatus performs wireless communication and an apparatus supporting the same are provided. The method may include: receiving information related to a physical sidelink feedback channel (PSFCH) resource from a base station; receiving a physical sidelink shared channel (PSSCH) from a second apparatus; and transmitting a PSFCH related to the PSSCH to the second apparatus. Here, the information related to the PSFCH resource may include, for example, information related to a resource block (RB) available for the first apparatus to transmit the PSFCH.

In a base station (100), when the number of layers employed is 1 and the employed antenna port and the antenna port used for transmitting the allocation control signal are the same, a transmission controller (102) sets a first data resource region inside a first resource region, in a resource block group (RBG), that can be used for the control channel or the data channel. When the number of layers employed is 1 and the employed antenna port and the antenna port used for transmitting the allocation control signal are different, a transmission controller (102) sets a second data resource region inside the first resource region in the RBG. The second data resource region is larger than the first data resource region.

A method of transmitting demodulation reference signals (DMRS) over one, three or five resource blocks (RBs) with Interleaved Frequency Division Multiple Access (IFDMA) from a wireless device to a wireless network node in a wireless network wherein Single Carrier Frequency Division Multiple Access (SC-OFDMA) is deployed in uplink, is provided. At least one of: a set of base sequences including thirty quadrature phase shifting keying, QPSK, sequences of length 6, 18 or 30 is determined, a demodulation reference signal sequence is derived from the determined set of base sequences, the demodulation reference signal sequence is multiplexed, and the multiplexed demodulation reference signal sequence is transmitted, by the wireless device, to the wireless network node.

Embodiments of the invention provide a method and a device for transmitting a signal based on resource mapping in an NOMA (Non-Orthogonal Multiple Access) system, and relate to the technical filed ofcommunication, wherein the method comprises the steps of: acquiring preset number of resource groups; for the each resource group, determining a corresponding relationship between each variable node of the resource group and channel nodes in physical resource blocks of the other resource groups to serve as a new corresponding relationship; and transmitting signals to each user according to a corresponding relationship included in the preset number of resource groups and the determined new corresponding relationship. Through adoption of the method provided by the embodiment of the invention, adetection bit error rate of a signal receiver can be reduced, and system reliability can be improved.

The invention provides a method, device and system for dispatching user equipment of a down link. Parts of physical resource blocks in a variable frequency band are selected to be added into a reserved frequency band according to resource load information of a first cell and channel condition information of a variable frequency band of a second cell, after the selected physical resource blocks are added into the reserved frequency band, resource load information of the second cell is provided, and the reserved frequency band of the second cell is determined according to the resource load information of the second cell to be used for dispatching the user equipment of the down link in the first cell. According to the method, device and system for dispatching the user equipment of the down link, more schedulable frequency band resources can be provided for one cell by expanding the reserved frequency band of an adjacent cell of the cell.
