Interference management employing fractional code reuse

Interference that occurs during wireless communication may be managed through the use of fractional reuse and other techniques. In some aspects fractional reuse may relate to HARQ interlaces, portions of a timeslot, frequency spectrum, and spreading codes. Interference may be managed through the use of a transmit power profile and/or an attenuation profile. Interference also may be managed through the use of power management-related techniques. In one aspect, an access point determines the set of spreading codes that will be used for the downlink and informs the associated access terminal (block 1402). An access point may also send information to the access terminal that identifies the spreading codes that are not being used by the access point and/or that identifies the spreading codes that are being used by some other access point (e.g., a neighbouring access point) (block 1408). The access terminal may then utilize the information received regarding the used spreading codes as well as the information regarding the spreading codes not used by the access point to more efficiently decode the received information (blocks 1410 and 1412). For example, this may be achieved by using interference cancellation techniques.
