摘要:
A relay may partially decode a frame to get enough information to know when to amplify and transmit the frame to a user. By limiting transmission in this way, less interference may be generated in some cases. By using only limited decoding, the relay overhead may be reduced in some embodiments.

A method and apparatus for determining a channel quality indicator (CQI) to be used in link adaptation for Orthogonal Frequency Division Multiplexing (OFDM) communications. In one embodiment of the invention, the CQI is based on a set of capacity values for subcarrier components in a received OFDM signal. In another embodiment, a minimum value from a running average of the set of capacity values is used to determine the CQI.

In a multiple-input multiple-output (MIMO) multicarrier communication system, a mobile station sends a quantized time-domain representation of the channel transfer function to a base station for use by the base station in generating beamforming coefficients for use in subsequent transmissions to the mobile station. In some embodiments, the quantized time-domain representation of the channel transfer function may be generated from selected most significant rays of an initial estimated sampled channel impulse response. Other embodiments may be described and claimed.
