Abstract: Embodiments of the present application provide a signal sending method, a device, and a system. A base station modulates, by using a first modulation scheme, signaling carried in a control channel, and modulates, by using a second modulation scheme, data carried in a traffic channel; and the base station sends, to UE, a signal obtained after modulation. In this way, the base station can independently select a modulation scheme for the control channel and the traffic channel, avoiding a case in which a modulation scheme used by the control channel and a modulation scheme used by the traffic channel must be the same, so that the base station can flexibly select a channel modulation scheme.

Abstract: Embodiments of the present invention provide a data transmission method, a base station, and a terminal device. The method includes: determining first indication information, where the first indication information is used to indicate a coding method that needs to be used for a service channel of to-be-transmitted data; and sending control signaling to a terminal device, where the control signaling includes the first indication information. In the embodiments of the present invention, the base station sends the first indication information to the terminal device by using the control signaling, so that the terminal device determines, according to the first indication information, the coding method that needs to be used for the service channel over which the to-be-transmitted data is transmitted.

Abstract: The present invention relates to the field of communications, and in particular, to a method for configuring a physical random access channel (PRACH) resource, a method for acquiring a PRACH resource configuration, a base station, and user equipment. The method for configuring a resource includes configuring, by a base station, a supported coverage enhancement level and a PRACH resource corresponding to the coverage enhancement level, and transmitting, by the base station to user equipment, a resource index and/or resource configuration information of the PRACH resource configured for the coverage enhancement level, so that the user equipment acquires the corresponding PRACH resource, and transmits a preamble on the acquired PRACH resource.

Abstract: Embodiments are provided to suppress the peak-to-average power ratio (PAPR) in MC-Multi-Carrier Code Division Multiple Access (MC-CDMA) and derivative systems. The embodiments include transmitter and receiver configurations for limiting the level of PAPR in the transmitted and received signals. The PAPR is limited to a PAPR of typical OFDM signals. At the transmitter, a sequence of Newman phase rotations (rotors) is applied to a sequence of transmitted signals prior to an inverse Fast Fourier Transform (FFT) function. With the correct choice of Newman phases, the PAPR of the transmitted signals is sufficiently suppressed. The sequence is also repeated for subsequently transmitted signals. At the receiver, the sequence of Newman rotors is removed after a FFT function. The transmitter and receiver are configured by adding an additional module or function without changing other existing used modules or functions.

Abstract: A radio communication system includes transmission/reception devices which perform communication by dynamically switching a first transmission mode and a second transmission mode having a lower quality than the first transmission mode, wherein the transmission/reception devices have a transmission mode decision means which fixes a transmission mode upon communication to the first transmission mode for a given period of time.

Abstract: Techniques are provided to assign radio resources with one of two or more types of assignments on a frame-by-frame basis. The first type of assignment uses subcarriers that are contiguous in both time and frequency, and the second type of assignment uses subcarriers that are disjoint and equally-spaced in frequency. The types of resource assignments can be multiplexed in a frame by dividing the frame into two zones, each zone of a different type. The demarcation between the first and second zones is implicitly indicated by the assignment messages for the mobile stations. Based on the loading conditions, the base station selects one of two demarcation strategies to use and communicates the selection implicitly by using one assignment message for a mobile station.
