DEVICE-TO-DEVICE (D2D) LINK ADAPTATION
First Claim
1. A method for measuring channel quality in a device-to-device (D2D) communication network, wherein the D2D communication network comprises one or more D2D wireless transmit/receive units (WTRUs), and wherein the D2D WTRUs communicate using a D2D bandwidth, the method comprising:
- receiving a channel measurement resource configuration corresponding to a channel measurement resource, wherein the channel measurement resource configuration comprises a reference signal (RS) bandwidth;
receiving an RS on the channel measurement resource;
measuring one or more channel state parameters from the channel measurement resource for a part of bandwidth overlapping with a D2D communication bandwidth, when the RS bandwidth is greater than the D2D communication bandwidth; and
reporting the channel state parameters to a controlling entity.

Abstract
Channel quality may be measured in a device-to-device (D2D) communication network. The D2D communication network may include one or more D2D wireless transmit/receive units (WTRUs), wherein the D2D WTRUs may communicate using a D2D bandwidth. A D2D WTRU may receive a channel measurement resource configuration corresponding to a channel measurement resource. The D2D WTRU may further receive an RS on the channel measurement resource. The D2D WTRU may measure one or more channel state parameters from the channel measurement resource for a part of bandwidth overlapping with a D2D communication bandwidth, when the RS bandwidth is greater than the D2D communication bandwidth. The D2D WTRU may report the channel state parameters to a controlling entity. The controlling entity may configure a D2D frequency allocation between a transmitting device and a receiving device. The D2D frequency allocation may be based on the time averaged measurement.
