Abstract:
1. A method, comprising: determining an anchor carrier, from a plurality of available carriers, assigned to an access point having a first access point power class, wherein the anchor carrier is assigned to the access point based at least in part on carrier assignment information, the carrier assignment information defining a first carrier assignment scheme for the access point, wherein the carrier assignment information specifies an anchor carrier reserved for an access point power class of a plurality of access point power classes for downlink control data transmissions and maximum power level associated with the anchor carrier based at least in part on the access point power class of the access point, wherein the first carrier assignment scheme specifies a first carrier designated as the anchor carrier, a second carrier reserved as an additional carrier, and power levels of the first carrier and the second carrier for downlink control data transmissions for the first access point power class, and wherein a disparate access point having a disparate access point power class has a second carrier assignment scheme that is different from the first carrier assignment scheme, wherein the second carrier assignment scheme specifies a third carrier designated as the anchor carrier and a power level of the third carrier for downlink control data transmissions for the disparate access point power class; receiving a first control data transmission from the access point using the anchor carrier at a first power level; transmitting interference information to the access point, the interference information based on interference received on the anchor carrier, wherein the interference is received from the disparate access point having the disparate access point power class; and receiving a second control data transmission from the access point using the second carrier at a second power level, wherein the second carrier and the second power level are selected based at least in part on the transmitted interference information and the second power level does not exceed the maximum power level specified in the carrier assignment information.
