Abstract
Methods, systems, and devices for wireless communications are described where a system bandwidth within a shared radio frequency spectrum band may be divided into multiple sub-bands. A base station may use a fallback downlink control information format to provide a resource grant to a user equipment, where the fallback downlink control information has a predetermined number of bits. To provide an indication of one or more of the sub-bands that are to be used for uplink communications when using fallback downlink control information, an explicit or implicit indication may be provided. Such sub-band indication may allow for the user equipment to use a particular sub-band that is available for transmissions in a shared radio frequency spectrum band. Indications of one or more sub-bands may be provided explicitly by a sub-band indication field in a fallback downlink control information, or implicitly by one or more downlink transmissions of a base station.
