Abstract: A scheduling request transmission method and a related device, used to solve the technical problem wherein no technical solution is currently available for providing SR feedback for terminals supporting different transmission time intervals. The method comprises: a terminal acquiring a first physical uplink control channel (PUCCH) resource corresponding to a first SR and a second PUCCH resource corresponding to a second SR, the first PUCCH resource being different from the second PUCCH resource; the first SR corresponding to a first transmission time interval (TTI) length, and the second SR corresponding to a second TTI length, the first TTI length being different from the second TTI length; the terminal determining whether the first SR and/or the second SR require transmission; if the first SR and/or the second SR require transmission, the terminal transmitting the first SR and/or the second SR by means of a PUCCH.

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: 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.
