US Patent 10461976 Cyclic prefix management in new radio

Aspects of the disclosure relate to wireless communication systems configured to provide techniques for managing the cyclic prefix (CP) type of a transmission as a function of one or more parameters, such as the transmission type (e.g., the type of channel or signal), the resources utilized for the transmission, or the tone spacing of the transmission. In some examples, at least a portion of the downlink and/or uplink control channels or signals utilize a CP having one duration, while other control channels or signals and/or traffic channels may utilize either the same CP or a different CP having a different duration. The CP type or duration for a given transmission may be indicated in various manners.
