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
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.

1. A method of wireless communication, comprising: determining, by a wireless communication device, a phase offset for a transmit power profile, wherein the transmit power profile specifies that transmit power is varied sinusoidally over time; andtransmitting, by the wireless communication device, according to the transmit power profile and the determined phase offset. 2. The method of claim 1, further comprising determining interference on a downlink, wherein the determination of the phase offset is based on the interference. 3. The method of claim 1, wherein the determination of the phase offset comprises selecting a phase offset associated with a relatively low level of interference on a downlink. 4. The method of claim 1, wherein the wireless communication device comprises an access point, and wherein the determination of the phase offset comprises the access point communicating with a neighboring access point to select a phase offset that is different than a phase offset used by the neighboring access point. 5. The method of claim 1, further comprising receiving at least one indication of maximum and minimum power levels and a time period for the transmit power profile from a network node, wherein the transmission is further based on the maximum and minimum power levels and the time period. 6.

The apparatus of claim 7, wherein the determination of the phase offset comprises selecting a phase offset associated with a relatively low level of interference on a downlink. 10. The apparatus of claim 7, wherein the apparatus comprises an access point, and wherein the determination of the phase offset comprises the access point communicating with a neighboring access point to select a phase offset that is different than a phase offset used by the neighboring access point. 11. The apparatus of claim 7, wherein the communication controller is further configured to receive at least one indication of maximum and minimum power levels and a time period for the transmit power profile from a network node, wherein the transmission is further based on the maximum and minimum power levels and the time period. 12. An apparatus for communication, comprising: means for determining a phase offset for a transmit power profile, wherein the transmit power profile specifies that transmit power is varied sinusoidally over time; andmeans for transmitting according to the transmit power profile and the determined phase offset. 13. The apparatus of claim 12, wherein the means for determining determines interference on a downlink, wherein the determination of the phase offset is based on the interference. 14. The apparatus of claim 12, wherein the determination of the phase offset comprises selecting a phase offset associated with a relatively low level of interference on a downlink. 15. The apparatus of claim 12, wherein the apparatus comprises an access point, and wherein the determination of the phase offset comprises the access point communicating with a neighboring access point to select a phase offset that is different than a phase offset used by the neighboring access point. 16. The apparatus of claim 12, wherein the means for transmitting receives at least one indication of maximum and minimum power levels and a time period for the transmit power profile from a network node, wherein the transmission is further based on the maximum and minimum power levels and the time period. 17. A non-transitory computer-readable medium comprising codes for causing a computer to: determine a phase offset for a transmit power profile, wherein the transmit power profile specifies that transmit power is varied sinusoidally over time; andtransmit according to the transmit power profile and the determined phase offset. 18. The non-transitory computer-readable medium of claim 17, further comprising codes for causing the computer to determine interference on a downlink, wherein the determination of the phase offset is based on the interference. 19. The non-transitory computer-readable medium of claim 17, wherein the computer comprises an access point, and wherein the determination of the phase offset comprises the access point communicating with a neighboring access point to select a phase offset that is different than a phase offset used by the neighboring access point. 20. The non-transitory computer-readable medium of claim 17, further comprising codes for causing the computer to receive at least one indication of maximum and minimum power levels and a time period for the transmit power profile from a network node, wherein the transmission is further based on the maximum and minimum power levels and the time period.
