Abstract: A wireless communication terminal that communicates on a plurality of sub-carriers divided into a plurality of frequency bands, wherein each frequency band includes at least one sub-carrier. The terminal measures a channel quality indicator (CQI) for a plurality of frequency bands, identifies a subset of frequency bands for which the channel quality indicator has been measured based on a subset criterion, and transmits a report identifying a subset of frequency bands for which a channel quality indicator has been measured or frequency bands not in the subset. In some embodiments, the report also includes a subset CQI value associated with at least the subset of frequency bands identified.

Abstract: A first user equipment (UE) and a second UE communicate with a network element (e.g., an eNB) over a carrier (e.g., an uplink or downlink cellular carrier). The first and second UEs also engage in D2D communication using resources of the carrier that have been allocated to them by the network entity. Using the allocated resources, the first and second UEs communicate using a subframe that has a first set of symbols in during which the first UE transmits, a second set of symbols during which the second UE transmits, and a guard interval between the first and second UEs.

Abstract: A display component (108) displays multiple icons that a user can touch. A sensing component (104) supports multiple resolution modes, including at least a high resolution mode and a low resolution mode. In one embodiment, in response to detecting an object touching one of the multiple icons while in the low resolution mode, at least a portion of the sensing component over the touched icon changes to operating in a high resolution mode. While in the high resolution mode, the user's fingerprint is sensed, and then the sensing component is returned to the low resolution mode. In another embodiment, icons are displayed in different regions of a display, and those different regions are associated with different sensing component resolutions. When an icon is touched, the touch is detected by the sensing component using the sensing component resolution associated with the region that includes the icon.
