Transmissions related to overhead may take up a larger percentage of symbols for shorter durations of the variable length uplink control channel. Disabling intra-slot hopping may be beneficial to decrease overhead (as a percentage). The apparatus may be an apparatus for wireless communication. The apparatus may include a transmitter or receiver and a processing system. The processing system may be configured to determine whether or not to use intra-slot frequency hopping for a variable length uplink control channel, and communicate information to the transmitter for transmission over the variable length uplink control channel or receive information from the receiver. The information may be received over the variable length uplink control channel, the information transmitted by the transmitter or received by the receiver based on the determination of whether or not to use intra-slot frequency hopping. ## Claims ### Claim 1 An apparatus for wireless communication, comprising: a transmitter; and a processing system configured to: determine whether or not to use
