Abstract: The application provides manner for communicating channel state information (CSI) in a communication network. A preset length is used for equalizing lengths of CSI to be reported. The preset length is determined based on a quantity of CSI-reference signal (RS) ports. A communication device determines whether a total length of one or more indication information items to be included in the CSI is less than the preset length. If the total length of the one or more indication information items to be included in the CSI is less than the preset length, the communication device adds one or more padding bits, to obtain a CSI bit sequence including the one or more indication information items and the one or more padding bits. A total length of the CSI bit sequence is consistent with the preset length. The communication device then outputs the CSI bit sequence.

Abstract: The present invention discloses an information transmission method, a device, and a system, and relates to the communications field, so as to resolve a problem that a receiving device has excessively large power consumption because the receiving device needs to continuously perform blind detection on a channel to determine a moment at which data transmission is started. A specific solution is: obtaining, by a network device, a start location of a first subframe, configuring a first field in downlink control information DCI of a second subframe, and sending, to user equipment, the first subframe and the second subframe that are adjacent to each other, where the first field is used to indicate the start location of the first subframe. The present invention is used for information transmission.

Abstract: The present disclosure provides an information transmission method, a device, and a system, and relates to the communications field, so as to resolve a prior-art problem that when an unlicensed spectrum is preempted to send data, a receive end cannot obtain a correct time resource sequence number, and cannot descramble information. A first device scrambles, according to a first scrambling code sequence, first data carried on a first time resource on an unlicensed carrier, where the first data is data that is sent by the first device to a second device, and the first scrambling code sequence is generated according to a sequence number of a second time resource on a licensed carrier or a first value; and the first device sends scrambled first data to the second device.
