Abstract: The present disclosure discloses a method and a device in a User and a base station used for channel coding. A first node determines a first bit block; performs channel coding; and transmits a first radio signal. Bits in the first bit block are used to generate bits in a second bit block. The bits in the first bit block and in the second bit block are used for an input to the channel coding, an output after the channel coding is used to generate the first radio signal. Channel coding is based on a polar code. A sub-channel occupied by a target first type bit is related to the number of bits in the second bit block related to the target first type bit. The target first type bit belongs to the first bit block. The disclosure can improve decoding performance of polar codes and reduce complexity of decoding.

Abstract: The present invention provides an uplink reference signal sending method, and the method includes: sending, by a terminal device, an uplink reference signal on N1 second component carriers within a determined uplink reference signal sending time, and prohibiting, on M1 first component carriers in M first component carriers within the sending time, the terminal device from sending an uplink signal, where the first component carriers are carriers on which scheduling of uplink data transmission is allowed, and the second component carriers are carriers on which scheduling of uplink data transmission is prohibited. N1=M1, in other words, within the sending time, a quantity N1 of second component carriers on which the uplink reference signal is sent is less than or equal to a quantity M1 of first component carriers on which sending of the uplink signal is prohibited.

Abstract: A system and method for real-time in-situ calibration of an Active Electronically Scanned Array (AESA) utilizes an S-parameter matrix-based EM transfer function between an end fire, unobtrusive, near field probe radiating element to minimize AESA look angle blockage. A sniffer probe is integrated in the AESA aperture of mechanical mounting frame or embedded with the AESA aperture structure. Hadamard orthogonal coding is utilized to simultaneously energize AESA elements.
