Method and apparatus for enhancing cell-edge user performance and signaling radio link failure conditions via downlink cooperative component carriers

A wireless transmit/receive unit (WTRU) in communication with a plurality of sites configured to manipulate their transmit power for a particular downlink (DL) component carrier (CC) operating frequency, the WTRU configured to establish a connection with the sites via respective DLs, each DL including at least one DL CC that operates on a frequency that is the same or different than one or more of the other DL CCs, wherein the distance from a particular one of the sites to its cell boundary becomes larger by increasing its transmit power of the particular DL CC operating frequency, and the distance from at least one of the other sites to its respective cell boundary becomes smaller by decreasing its transmit power on the particular DL CC operating frequency.

A wireless communication network comprising:

• a plurality of sites configured to manipulate their transmit power for a particular downlink (DL) component carrier (CC) operating frequency;
• and
• a wireless transmit/receive unit (WTRU) configured to establish a connection with the sites via respective DLs, each DL including at least one DL CC that operates on a frequency that is the same or different than one or more of the other DL CCs, wherein the distance from a particular one of the sites to its cell boundary becomes larger by increasing its transmit power of the particular DL CC operating frequency, and the distance from at least one of the other sites to its respective cell boundary becomes smaller by decreasing its transmit power on the particular DL CC operating frequency.
