Abstract: Embodiments of this application provide a method for reporting user equipment capability information and related device. A user equipment (UE) receives user equipment capability enquiry information sent by a network device, and reports the carrier aggregation capability of the user equipment by sending user equipment capability information to the network device, where the carrier aggregation capability of the user equipment includes the information that the downlink carriers of the UE in different radio access technologies are contiguous and the uplink carriers of the UE in the different radio access technologies are non-contiguous.

Abstract: Embodiments of this application provide a multistation coordination-based data transmission method and apparatus. The method includes: receiving, by a station, second data of another station, different from the station, in a coordination group to which the station belongs; sending, by the station, first data to the other station, so that the other station generates a second aggregated frame that includes the first data and the second data; and sending, by the station, a first aggregated frame to an access point. The first aggregated frame includes the first data and the second data. This reduces a transmit power of a single station, and prolongs a service lifespan of the station.

Abstract: The disclosure relates to performing phase compensation at a transmitter. A processing device for a network access node generates a phase compensated modulation symbol based on at least one first modulation symbol and at least on one of a frequency offset parameter and a time offset parameter. The frequency offset parameter may be determined based on an offset between a reference frequency f0 and a DC (0 Hz) frequency such that the frequency offset parameter corresponds to the reference frequency f0. Also, the reference frequency f0 can be at least partly based on the carrier of up-conversion frequency used by the processing device and the reference frequency f0 can be the carrier for up-conversion frequency. The phase compensated symbol is transmitted to a receiver, such as a client device. Furthermore, the disclosure also relates to corresponding methods and a computer program.

Abstract: A method and apparatus. The method includes: a terminal device sends a carrier aggregation (CA) capability reporting message to a network device, where the CA capability reporting message includes a frequency separation class of each of at least one radio frequency (RF) channel of the terminal device and a power amplifier (PA) architecture of the terminal device. The PA architecture indicates that the PA architecture that can be used by the terminal device to support CA is a single PA and/or a plurality of PAs. The network device can improve CA resource configuration flexibility by using the foregoing method.

Abstract: A first device sends a first message to a second device, where the first message indicates to the second device to hop to different channels at different times to send radio signals. The frequency bandwidth ranges of any two channels do not completely overlap, and the frequency bandwidth range of each channel is within a total frequency bandwidth range supported by the first device. The first device separately receives the radio signals that are sent by the second device on different channels at different times. The radio signals reach the first device after being reflected by an intermediate object. The first device measures the state information of the intermediate object based on the physical characteristics of the different radio signals that are separately received.

Abstract: This application discloses an information transmission method, apparatus, and system, and belongs to the field of communications technologies. The method includes: generating, by a base station, amount indication information, where the amount indication information is used to indicate a maximum amount of downlink control information; sending, by the base station, the amount indication information to user equipment; receiving, by the user equipment, the amount indication information; and receiving, by the user equipment, downlink control information based on the amount indication information. In this application, the amount indication information is sent to the user equipment, so that the user equipment receives the downlink control information based on the amount indication information. This can resolve a problem that complexity of blind detection performed by the user equipment is relatively high, thereby reducing the complexity of the blind detection performed by the user equipment.
