Enhanced fragmented sector level sweep procedure in MMW WLAN systems

A first communication device comprising:

• a processor;
• a transmitter;
• and
• a receiver;
• wherein the processor and the transmitter are configured to transmit a plurality of beacon frames in a corresponding plurality of transmit sectors, wherein the plurality of beacon frames are transmitted within a beacon interval;
• wherein the receiver is configured to receive, 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
• wherein the receiver is configured to receive, 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.
