Abstract

The invention provides a millimeter wave band unlicensed spectrum access and beamforming method and device, and aims to solve the problem of sharing of unlicensed frequency bands in millimeter wave bands and the problem of joint allocation of frequency and space resources. The method comprises the following steps: occupying a plurality of idle unauthorized millimeter wave channels according to channel detection of an unauthorized millimeter wave channel by a base station and cellular user terminals; iteratively optimizing RF precoders and digital precoders of all cellular user terminal accesschannels to obtain a target RF precoder and a target digital precoder; and according to the target RF precoder and the target digital precoder of the channel where the cellular user terminals are located, obtaining respective total utility of candidate channels which can be selectively accessed by the cellular user terminals, and allocating the cellular user terminals to the channel with the highest total utility to obtain channel allocation results of all the cellular user terminals, wherein the cellular user terminals and a WiGig user terminal share the unauthorized millimeter wave channel in the allocation result for data transmission.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for accessing unlicensed spectrum in the millimeter wave band and beamforming. Background technique [0002] With the development of the Internet of Things, a large number of smart devices with huge data traffic requirements need to be deployed in wireless networks. Various mobile applications in the future 6G era, such as autonomous driving of cars and enabling virtual reality (VR) with rich sensing information, need to rely on ultra-high data transmission rates. Millimeter wave communication is considered to be an effective solution to the current dilemma, enabling multi-gigabit data rates for numerous devices. [0003] However, it is still difficult to meet these 6G requirements only by relying on the licensed mmWave frequency band. Original user terminals on the licensed mmWave band share the unlicensed mmWave band. At present, th...
