1. A method performed by a first communication device, the method comprising:
transmitting a plurality of beacon frames in a corresponding plurality of transmit sectors, wherein the plurality of beacon frames are transmitted within a beacon interval;
receiving, from a second communication device, a first transmission including information representing a first ranked list of at least a first subset of the plurality of transmit sectors, wherein the first ranked list is based on a characteristic, observed by the second communication device, of the at least the first subset of the plurality of transmit sectors, wherein the first transmission is received in a sector corresponding to one of the transmit sectors of the first subset of the plurality of transmit sectors; and
receiving, from a third communication device, a second transmission including information representing a second ranked list of at least a second subset of the plurality of transmit sectors, wherein the second ranked list is based on a characteristic, observed by the third communication device, of the at least the second subset of the plurality of transmit sectors, wherein the second transmission is received in a sector corresponding to one of the transmit sectors of the second subset of the plurality of transmit sectors.
