摘要:
Spectrum access for Internet of things (IOT) applications including receiving information about expected use by a primary user of a spectrum band in a radio frequency spectrum. The spectrum band is classified into at least two working modes based on the expected use. The spectrum band is sensed to determine a current access pattern of the primary user. Based on the classifying and the sensing, one of the working modes is selected as a current working mode of the primary user. Transmissions are scheduled on the spectrum band using a current schedule that is responsive to the current working mode of the primary user. If the current working mode of the primary user changes, the sensing, selecting, scheduling, and determining whether the current working mode has changed are re-performed. Otherwise, the transmission scheduling and determining if the current working mode has changed are re-performed.

摘要:
A method and apparatus for reducing spectrum interference between wireless networks. This is realized by arranging at least one sub-coordinating apparatus, namely, a monitoring apparatus, in respective wireless network, and by arranging a coordinating apparatus, namely, an allocation apparatus in the whole network. Wherein, the sub-coordinating apparatus monitors the spectrum utilization situation of the wireless network where it is located, reports it to the coordinating apparatus, and requests the coordinating apparatus for spectrum resource when new spectrum resource is needed. The coordinating apparatus maintains the spectrum utilization information of each wireless network, and allocates appropriate spectrum resource to the sub-coordinating apparatus which requests spectrum resource based on the maintained information. Therefore, the interference of inter-wireless networks is reduced or even avoided through such overall management that the coordinating apparatus allocates corresponding spectrum resources to a plurality of wireless networks capable of sharing spectrum resources.

A wireless communication system base station, and a remote radio head (RRH) and a computer-implemented synchronization method for the wireless communication system base station. The RRH is communicably coupled to a baseband unit (BBU) of the wireless communication system base station through a network, and the BBU processes and transmits downlink data to the RRH. The RRH includes: a time-delay measurement unit for measuring a time-delay for the downlink data to arrive at the RRH from the BBU; and a time-delay notification unit for notifying from the RRH to the BBU of time-delay data on the time-delay measured by the time-delay measurement unit, wherein the time-delay data is used to advance the starting time for the BBU to process and transmit the downlink data by an amount of time obtained based on the time-delay data.
