Abstract: This application provides example methods for controlling an output power of an antenna for user equipment. One example method includes, during a sounding reference signal (SRS) transmission period, transmitting, by a first antenna of at least one antenna of the user equipment, a first SRS signal to a base station at a first SRS output power, where the first SRS output power is equal to a maximum output power (Pcmax) of the first antenna. During the SRS period, a non-SRS signal is transmitted to the base station at a non-SRS output power, where the non-SRS output power is less than a difference between the maximum output power of the first antenna and a maximum output power reduction of the first antenna, and the maximum output power reduction of the first antenna is set to meet an electromagnetic power density exposure requirement of the first antenna.

Abstract: Embodiments of this application provide a data transmission method and apparatus and a storage medium. The method includes: After obtaining a first identifier and a second identifier that uniquely identify a first device, the first device scrambles, by using the first identifier, checked data obtained through CRC check. After performing channel coding on to-be-transmitted data and scrambled checked data, the first device scrambles, by using the second identifier, coded data obtained through channel coding, and finally sends scrambled data. In this way, after receiving the scrambled data, a second device may perform descrambling by using the second identifier, and then perform CRC check, to determine whether the received data is correct and determine the first identifier of the first device.

Abstract: The present application describes a control information transmission method, a terminal device, a network side device, and a communications system. The method may be implemented by a terminal device and include determining, based on a preset mapping relationship between bit combinations and modulation symbols, a modulation symbol corresponding to a to-be-transmitted bit combination and a resource used to send the determined modulation symbol, where in the mapping relationship, each bit combination corresponds to one modulation symbol to be sent on a first resource or one modulation symbol to be sent on a second resource. In bit combinations corresponding to modulation symbols sent on at least one of the first resource and the second resource, SR bits in at least two bit combinations are different, and ACK/NACK bits in at least two bit combinations are different. Furthermore, the method may include sending, on the determined resource, the modulation symbol corresponding to the to-be-transmitted bit combination.

Abstract: In accordance to embodiments, methods, devices, and systems for determining initial transmissions in grant-free transmissions are disclosed. A UE receives a resource configuration for grant-free (GF) transmissions. The resource configuration comprises a periodicity parameter (P), a repetition number (K), and a sequence of redundancy version (RV) numbers corresponding to one or more RV types. The periodicity parameter defines a period having K transmission occasions (TOs), and each of the KTOs is associated with one RV number in the sequence of RV numbers. The UE performs an initial GF transmission of data in a TO of the K TOs in the period defined by the periodicity parameter. The TO is associated with an RV number corresponding to RV0.

Abstract: This application relates to a scheduling method and a device. In the scheduling method, a base station sends, at a first moment, uplink grant (UL GRANT) information to a terminal that is to perform uplink data transmission; the base station sends, at a second moment, downlink data to a terminal that is determined by the base station and that is to perform downlink data transmission, where the second moment is a moment at which the terminal that is to perform uplink data transmission sends uplink data after receiving the uplink grant information at the first moment.

Abstract: The present disclosure discloses a data processing method, a network device, and a terminal. In this method, a transmit end combines basic modulation symbols obtained after basic modulation is performed on all layers of data, to obtain a combined symbol vector X. The transmit end maps the symbol vector X to Q resource elements to obtain a data vector S. A symbol quantity of the symbol vector X is greater than a symbol quantity of the data vector S. The symbol quantity of the data vector S is Q. Q is a positive integer. Therefore, non-orthogonal spreading and superposition transmission of a plurality of terminals can be implemented in both uplink and downlink, thereby effectively improving transmission efficiency.
