Abstract: Disclosed in the present application are a data transmission method and device. The method comprises: a base station sends a signaling notification to a terminal, so that the terminal determines, according to the signaling notification, whether a pilot signal of data transmitted using a second transmission time interval exists within a first transmission time interval, wherein the first transmission time interval is shorter than the second transmission time interval, or the priority of a service carried by the first transmission time interval is higher than the priority of a service carried by the second transmission time interval, there is a resource overlap between the first transmission time interval and the second transmission time interval, and the terminal using the first transmission time interval for data transmission knows a pilot signal location of the data transmitted using the second transmission time interval; and the base station performing transmission according to a pilot signal resource location of the second transmission time interval. The present application can ensure that a receiving end for other service transmissions can use a pilot signal for data demodulation, thereby avoiding the waste of resources caused by the destruction of the pilot signal.

Abstract: The present invention relates to the technical field of communications, and specifically relates to a method and device for determining the initial positions of a downlink data channel. The present invention solves the problem of determining the initial positions in the time domain of a downlink data channel when the resources occupied by a downlink control channel in the time domain are variable. The method comprises: a base station transmits to a terminal a generated indication signaling, and the terminal determines, on the basis of the received indication signaling, the time domain initial positions of the downlink data channel in L downlink TTIs. With said method, when the downlink control channel only appears in a part of the positions in a frequency domain or does not appear at all, and when the downlink control channel does not occupy the complete downlink control area in the time domain or the resources occupied by the downlink control channel in the time domain are variable, the base station can still accurately notify the terminal the time domain initial positions of the downlink data channel, so that the terminal can accurately receive downlink data, thereby enhancing the efficiency and reliability of the terminal reception of downlink data, and further enhancing the spectrum efficiency as well as the user experience.

Abstract: Disclosed are a data transmission method, device, and system. The method comprises: for the transmission of random access uplink data, according to the correspondence between preambles and data resources as described by a protocol, determining the data resource corresponding to the preamble in the uplink data transmission, different preambles corresponding to different data resources; transmitting the preamble and the uplink data that uses the determined data resource. In the embodiments of the present invention, a protocol describes the correspondence between preambles and data resources. For the transmission of random access uplink data, the data resource corresponding to the preamble in the uplink data transmission can be determined, and different preambles correspond to different data resources. Thus it can be ensured that different users use different data resources to bear uplink data, thereby enabling the data portion multiplexing for multiple users.

Abstract: The present application discloses a method and an apparatus for transmitting uplink control information (UCI), to resolve the issue of repeated transmissions of UCI in the prior art. In an embodiment of the present application, a terminal determines a bit sequence of coded UCI of a first transmission, the UCI being repeatedly transmitted on a PUCCH, and the terminal transmits the bit sequence of the coded UCI in a determined uplink channel in each subsequent retransmission of the UCI. A network side apparatus uses the same method to determine a bit sequence of coded UCI of a first transmission, and receives, via a determined uplink channel, a repeatedly transmitted bit sequence of the coded UCI. In the embodiments of the present application, a bit sequence of coded UCI is determined according to a channel of the UCI in a first transmission time slot.

Abstract: Disclosed are a transmission method, a terminal, and a base station, for use in resolving the technical problem in the prior art that a base station cannot perform accurate uplink scheduling for a scheduling request (SR) of a terminal due to that there is no explicit solution for how to distinguish which SR in a plurality of SR configuration is transmitted simultaneously with other UCIs. In the transmission method for distinguishing a plurality of SR configurations provided by embodiments of the present disclosure, the terminal cascades an M-bit SR with a first UCI and simultaneously transmits same, and M-bit SR information is used for indicating SR states of the plurality of SR configurations of the terminal, ensuring that a base station performs correct uplink scheduling on the terminal.
