Abstract: Embodiments of the present invention disclose a signal receiving method, a signal transmission method, and a device, and relate to the communications field, so as to resolve a problem that a supported quantity of UEs that perform orthogonal code division multiplexing through cyclic shifts is relatively small when a frequency deviation between a center frequency for receiving a signal by UE and a center frequency for transmitting a signal by a base station is greater than a subcarrier spacing used for communication between the base station and the UE. The embodiments of the present invention are used in a signal transmission process.

Abstract: A sequence-based signal processing method and apparatus are provided. A sequence meeting a requirement for sending a signal by using a physical uplink control channel (PUCCH) is determined, where the sequence is a sequence {ƒn} consisting of N elements, ƒn is an element in the sequence {ƒn}, and the determined sequence {ƒn} is a sequence meeting a preset condition; then, the N elements in the sequence {ƒn} are respectively mapped to N subcarriers to generate a first signal; and the first signal is sent. By using the determined sequence, when a signal is sent by using a PUCCH, a low sequence correlation can be maintained, and a relatively small peak-to-average power ratio (PAPR) value and cubic metric (CM) value can also be maintained, thereby meeting a requirement of a communication application environment in which a signal is sent by using a PUCCH.

Abstract: Embodiments of the present invention provide a power usage state information transmission method and apparatus. The transmission method for transmitting power usage state information according to the present invention includes: determining, by a terminal device, a power headroom PH of a second cell corresponding to the terminal device; and sending, by the terminal device to the first network device, the PH and channel configuration information corresponding to the PH. According to the embodiments of the present invention, the first network device can readily acquire, according to the PH and the channel configuration information, a power usage state of the second cell corresponding to the terminal device. In this way, transmit power of UE between different network devices can be properly allocated, and therefore, system resources are properly used.

Abstract: A sequence distributing and sequence processing method and apparatus in a communication system are provided. The sequence distributing method includes the following steps: generating sequence groups including a number of sequences, the sequences in the sequence groups are determined according to the sequence time frequency resource occupation manner which is supported by the system; distributing the sequence groups to cells. The method avoids the phenomenon that signaling transmission is needed to distribute the sequences to the cells for different time frequency resource occupation manner, and saves in so far as possible the wireless network transmission resource occupied during the process of distributing the sequences through distributing the sequence groups comprising a number of sequences to the cells.

Abstract: Embodiments of the present disclosure provide, among other implementations, sequence determining methods. One example method provides a sequence group, and one sequence group number is corresponding to at least two sequences, where one sequence is used for mapping to consecutive subcarriers, and at least one other sequence is used for mapping to equally-spaced subcarriers. In some embodiments of the present disclosure, as high as possible cross-correlation between a sending signal obtained after equally-spaced mapping is performed on a sequence in a sequence group can be determined, and a sending signal obtained after continuous mapping is performed on another sequence in the group.
