Abstract: Embodiments provide a Polar code transmission method and apparatus. A bit sequence is encoded into a code sequence using Polar code by a network device. The bit sequence contains a control signaling and a Cyclic Redundancy Code (CRC) sequence. The code sequence is transformed into M copies such that an ith information copy of the M copies multiples by a first matrix of the power of (i−1). M is an integer and M>0. M copies of codeword was encoded by Polar code, the M copies implicitly conveys different time stamp information, which is suitable for the transmission of PBCH in 5G communication system, signaling overhead is also reduced.

Abstract: A control information sending method, a control information receiving method, and a device, where a first device sends first control information to a second device on a first resource such that second device prepares data information based on the first control information and waits for sending the data information. The first device sends second control information on a second resource different from the first resource such that the second device sends the data information based on the second control information. The first resource is different from the second resource such that a duration of preparing the data information by the second device is greatly greater than an interval between control information and uplink data in one time interval, and the second device has sufficient time to prepare the data information.

Abstract: A method for adjusting power of a terminal includes monitoring, by the terminal, usage of an uplink carrier, where the carrier usage includes at least one of a quantity of carriers, duration of continuous use of one or more carriers, and a temperature of the terminal. The method further includes adding, by the terminal, a power back-off value during calculation of power headroom when the terminal detects that the carrier usage satisfies a preset condition, to reduce a value of power headroom of the one or more carriers. The method further includes reporting, by the terminal, the value of the power headroom to a network device.
