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 LTE 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 application discloses a physical uplink shared channel data transmission method and device. The method comprises: a terminal adjusts or schedules, according to detected downlink control channel data utilizing an uplink DCI format and/or PHICH data in a subframe n, PUSCH data to be transmitted in a special subframe (n+k), wherein k is a predefined value. A base station transmits the downlink control channel data utilizing the uplink DCI format and/or the PHICH data in the subframe n, to adjust or schedule the terminal to transmit the PUSCH data in the special subframe (n+k), wherein k is a predefined value. The application provides a schedule timing definition for transmitting PUSCH data in a special subframe, thereby ensuring normal transmission of the PUSCH data in the special subframe.

Abstract: A method and device for transmitting uplink control information is described. The method includes according to the size and position of a feedback window, determining uplink control information; according to a transmission moment of the uplink control information, performing listen-before-talk detection to determine an actual uplink transmission moment; and transmitting the determined uplink control information at an actual uplink transmission moment. In the embodiments of the present disclosure, under the situation where no channel is occupied at a set uplink control information transmission moment, one or more times of listen-before-talk detection are continued, and the determined uplink control information is transmitted on an actual uplink transmission moment, thereby avoiding the situation that uplink control information may not be correctly transmitted in time due to not occupying a channel, and further improving the system performance.
