Abstract

The invention brings forward a method and apparatus for communication on a non-authorized frequency band. For the purpose of solving the problem of interference generated when different service provider devices are disposed at the same non-authorized frequency spectrum, a base station sends one or two from a first signaling indication positive integer N and a rational number R on first carrier waves, wherein the R is not smaller than 0 and not greater than 1, the N is used for identifying a continuous subframe number occupied by physical signals processed by the base station on the first carrier waves on a time domain, and the R is used for identifying the proportion which subframes scheduled by the base station account in subframes of a given time window; and a base station adjacent to the base station, according to the N, helps to determine scheduling subsframes available on the first carrier waves, the adjacent base station, according to the R, helps to determine the number of the scheduling subframes available in the given time window on the first carrier waves. According to the scheme provided by the invention, a conventional sequence or signaling is reused as much as possible for indicating a first signaling so that the computability with a conventional system is maintained to a maximum degree.

Description

technical field [0001] The present invention relates to a scheduling scheme in a wireless communication system, in particular to a scheduling scheme based on a long-term evolution (LTE-Long Term Evolution) unlicensed spectrum (Unlicensed Spectrum). Background technique [0002] In the traditional 3GPP–3rd Generation Partner Project (3GPP–3rd Generation Partner Project) LTE system, data transmission can only occur on the licensed spectrum. However, with the rapid increase of traffic, especially in some urban areas, the licensed spectrum may be difficult Meet the needs of business volume. The 62nd plenary meeting of 3GPP RAN discussed a new research topic, that is, the research on unlicensed spectrum synthesis (RP-132085), the main purpose of which is to study the non-standalone (Non-standalone) deployment of LTE on unlicensed spectrum, the so-called Non-independent means that the communication on the unlicensed spectrum must be associated with the serving cell on the license...
