Abstract: The application provides an uplink transmission method, a network side device and a terminal. The uplink transmission method includes that a terminal receives first configuration information at a first-time-domain position, and receives second configuration information at a second-time-domain position, in which the first configuration information indicates frequency-domain resource information of an uplink shortened Transmission Time Interval (sTTI) transmission performed by the terminal at a third-time-domain position, and the second configuration information indicates scheduling information for the uplink sTTI transmission performed by the terminal at the third-time-domain position; and the terminal performs the uplink sTTI transmission at the third-time-domain position, according to the first and second configuration information.

Abstract: The application discloses an ACK/NACK feedback method and an associated apparatus serving to resolve the problem arising from data in different transmission time intervals having different transmission and processing latencies, leading to different earliest time points to transmit an ACK/NACK feedback message, and subsequently resulting in being unable to ensure normal ACK/NACK feedback in downlink transmission. The method comprises: a terminal receives a first physical downlink control channel having downlink control information containing a first indication field, the first indication field indicating a time-domain position of ACK/NACK feedback message; and the terminal determines, according to the first indication field, the first physical downlink control channel or the time-domain position of the ACK/NACK feedback message of a first physical downlink shared channel corresponding to the first physical downlink control channel, and transmits, at the time-domain position of the ACK/NACK feedback message, the ACK/NACK feedback message.

Abstract: A narrowband PBCH transmission method and a narrowband PBCH transmission device are provided. A network side device transmits a narrowband PBCH carrying at least CRS transmission indication information. The CRS transmission indication information is to indicate the CRS port number and/or CRS frequency domain position in the LTE system. Through the CRS transmission indication information, it is able to enable the narrowband terminal working simultaneously with the LTE terminal in the LIE bandwidth to obtain the CRS in the LTE system, so that the narrowband downlink transmission may be demodulated through the CRS of the LTE system, and then the signal reception based on the CRS may be realized.

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.
