Abstract: Embodiments of the present invention disclose a queue scheduling method and apparatus, which can not only implement scheduling of a large number of queues, but also ensure that the queues uniformly send service data. The method includes: determining whether service data exists in each to-be-scheduled data queue and determining whether the to-be-scheduled data queues are allowed to send data; if it is determined that the service data exists in the to-be-scheduled data queues and the to-be-scheduled data queues are allowed to send data, placing queue marks of the to-be-scheduled data queues into a mark queue; scheduling queue marks of the to-be-scheduled data queues from the mark queue in sequence, scheduling the to-be-scheduled data queues corresponding to the queue marks, and enabling the to-be-scheduled data queues corresponding to the queue marks to send service data not exceeding predetermined data amounts.

Abstract: The present invention provides a preamble sequence sending and receiving method and apparatus, and a system. The preamble sequence sending method includes: generating, by a transmit end, a frequency offset estimation sequence, where the frequency offset estimation sequence includes N subsequences each with a length of M, N is a positive integer greater than or equal to 2, and M is a positive integer; generating, by the transmit end, a prefix and a suffix based on the frequency offset estimation sequence; adding, by the transmit end, the prefix and the suffix before and after the frequency offset estimation sequence respectively to form a preamble sequence, where the prefix and the suffix are used for canceling multipath interference; and adding, by the transmit end, the preamble sequence to a data packet and sending the data packet to a receive end.
