Abstract

In accordance with some embodiments, a user equipment or mobile station may provide assistance to the eNB or base station so that eNB or base station can more effectively provide settings to the user equipment. Because the user equipment may have more in depth knowledge about the conditions that exist at the user equipment, efficiencies may be achieved by providing information to the eNB from which the eNB can better set various settings on the user equipment, including those related to power saving and latency.
