Abstract
A BS may transmit a first signal using a first group of one or more tones, transmit a second signal using a second group of one or more tones, and transmit a third signal using a third group of one or more tones in a GB between the first and second groups of tones. In one example, the transmitting comprises controlling a transmit power of at least one tone of the third group of one or more tones in the GB. The at least one tone of the third group of tones is on a different frequency grid than the first group of one or more tones or the second group of one or more tones. A UE may perform corresponding transmit power control operations for UL transmissions in a GB.
