Method and devices for use in a wireless device are described herein. A signal is received over a plurality of time segments, the signal over each time segment including a plurality of resource element blocks. For each time segment, at least one resource element block is selected from the plurality of resource element blocks of the time segment based on information determined about the time segment. For each time segment, a power value associated with the at least one resource element block of the time segment is determined. For each time segment, a gain adjustment value to adjust the gain of the time segment or one or more subsequent time segments of the signal is determined based upon the power value associated with the at least one resource element block.

Power based gain control adjustment

There are disclosed systems and methods that dynamically vary the word length of data being transmitted through a digital interface. In one embodiment, the method comprises: (i) obtaining at least one parameter indicative of a quality of a signal; (ii) if the at least one parameter indicates that the quality of the signal is above a threshold, then transmitting the data as a number of digital words at a first predetermined word length; (ii) if the at least one parameter indicates that the quality of the signal is below the threshold, then transmitting the data as a number of digital words at a second predetermined word length. The second predetermined word length is different from the first predetermined word length.
