The uplink signal is used to trigger a base station to send first system information, and the first system information is used by the terminal to camp on a cell. In the embodiment method, correspondingly, the base station receives the uplink signal sent by the terminal, and the base station sends the first system information on a beam in which the terminal is located. In the embodiment method, correspondingly, the terminal receives the first system information sent by the base station on the beam in which the terminal is located.

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 {fn} consisting of N elements, fn is an element in the sequence {fn}, and the determined sequence {fn} is a sequence meeting a preset condition; then, the N elements in the sequence {fn} 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: The present invention relates to the field of communications technologies, and in particular, to a data scheduling method and apparatus, so as to resolve a problem that performing data scheduling on a data node by different evolved NodeBs participating in CA may cause a case in which a range supported by a processing capability of the data node is exceeded, or may cause a case in which the data node cannot fully leverage a processing capability of the data node. The method includes: sending, by the data node, scheduling limitation indication information to a first communications node; receiving, by the data node, data scheduling information that is sent by the first communications node to the data node; and sending, by the data node, uplink data to the first communications node, or receiving, by the data node, downlink data sent by the first communications node according to the data scheduling information.
