Abstract:Spectrum is a scarce and non-renewable resource. This paper proposes an improved adaptive spectrum access mechanism for unlicensed millimetre waves, which is based on the problem of low spectrum utilisation due to the high signalling overhead of the receiver-assisted Listen Before Talk (LBT) mechanism. By introducing an adaptive duty cycle to the receiver-assisted LBT frame structure, the system parameters can be adaptively adjusted to ensure that New Radio-based Access to Unlicensed Spectrum (NR-U) and Wirele… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
