SYSTEM AND METHOD FOR EFFICIENT BANDWIDTH UTILIZATION

WIPO Patent Application WO/2018/028625

A1

Systems and method for defining sub-bands are provided. Each sub-band has a respective sub-carrier spacing, and at least one sub-band portion. Each sub-band portion has a channelization configuration including a resource block size configuration and a sub-band portion bandwidth. The sub-bands are allocated based on a sub-band configuration framework that includes a preconfigured set of possible sub-carrier spacings, a preconfigured set of possible resource block sizes, and a preconfigured set of possible sub-band portion bandwidths. In some embodiments, to improve bandwidth utilization, the channelization configuration for a given sub-band configures a plurality of resource blocks having a first number of sub-carriers and an additional resource block having a number of sub-carriers other than the first number. A bandwidth portion may include two bandwidth portions having different channelizations with differing numbers of sub-carriers per resource block such that more useful sub-carriers are used than would be possible if only resource blocks having a largest of the differing numbers of sub-carriers were used.
