7. An apparatus comprising:
at least one processor; and
at least one memory including computer program code;
the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
determine, by a user equipment in a wireless network, a starting physical resource block of a common physical resource block grid that is associated with a wideband channel, wherein a plurality of bandwidth parts is provided within the common physical resource block grid, each bandwidth part having a bandwidth that is less than the bandwidth of the wideband channel;
determine, by the user equipment, a wideband channel guard band for the wideband channel, the wideband channel guard band provided between a lowest frequency of the wideband channel and a first usable physical resource block of the common physical resource block grid; and
determine, by the user equipment for at least one bandwidth part of the plurality of bandwidth parts, a bandwidth part-specific physical resource block grid that is a subset of the common physical resource block grid;
wherein the plurality of bandwidth parts comprises:
at least a first temporal bandwidth part that is temporarily available for use by the user equipment for transmission or reception based on a positive clear channel assessment, performed by either the user equipment or a base station, for one or more sub-bands of the at least first temporal bandwidth part; and
at least a second bandwidth part that is unavailable for use by the user equipment for transmission or reception based on a negative clear channel assessment, performed by either the user equipment or the base station, for one or more sub-bands of the at least first temporal bandwidth part.
