    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.

    Abstract: A method to explicitly indicate the version information while still supporting soft combining is disclosed. A polar code encoder maps q bits to q positions of q sub-channels, q is a positive integer; wherein the q bits are used to indicate a version of encoded codeword; map 1 to a special frozen bit corresponding to the q bits; map K−q information bits to K−q positions for the K−q information bits, K is an integer, K>q; and perform polar encoding over an input vector u0N-1, comprising the q bits, the special frozen bit and the K−q information bits, with the length of N, N is an integer, N>=K. With this method, there is no need to make blind detection to achieve the version information of transmitted payload, which reduces power consumption for a receiver.

    Abstract: A sounding reference signal sending method and user equipment are disclosed. The method includes the following steps: receiving a configuration parameter of a sounding reference signal SRS, and determining, based on the configuration parameter, a time-frequency resource occupied by the SRS, where the configuration parameter includes a trigger type, a period parameter, and a time-frequency resource location identifier; obtaining a power control parameter of the SRS, and calculating, based on the power control parameter and a preset calculation formula, a transmit power for sending the SRS; and sending the SRS on the time-frequency resource at the transmit power. The trigger type includes beamforming and non-beamforming. The period parameter is an identifier used to indicate that the SRS is sent periodically or aperiodically.
