Abstract
Methods, systems, and apparatuses are disclosed for reducing interference between wireless network cells. The embodiments may include: transmitting, by a base station, a physical broadcast channel in predetermined time slots in a frame; receiving, by the base station, interference information for other base stations indicating interference levels associated with its wireless transmit/receive units (WTRUs); wherein particular neighboring base stations having high interference are identified based on the received interference information; and reducing, by the base station, transmission power in the predetermined time slots in response to the interference levels.
Claims9
A base station comprising:
- circuitry configured to transmit a physical broadcast channel in predetermined time slots in a frame;
- wherein the circuitry is further configured to receive interference information for other base stations indicating interference levels associated with its wireless transmit/receive units (WTRUs);
- wherein particular neighboring base stations having high interference are identified based on the received interference information;
- and
- wherein the circuitry is further configured to reduce transmission power during the predetermined time slots in response to the interference levels.
A method for use by a base station comprising:
- transmitting, by the base station, a physical broadcast channel in predetermined time slots in a frame;
- receiving, by the base station, interference information for other base stations indicating interference levels associated with its wireless transmit/receive units (WTRUs);
- wherein particular neighboring base stations having high interference are identified based on the received interference information;
- and
- reducing, by the base station, transmission power in the predetermined time slots in response to the interference levels.
A wireless transmit/receive unit (WTRU) comprising:
- circuitry configured to receive a physical broadcast channel in predetermined time slots in a frame;
- wherein the circuitry is further configured to receive, at a reduced power, a dedicated transmission in the predetermined time slots;
- wherein the scheduling information is derived for interference information from other base stations indicating interference levels associated with its WTRUs;
- wherein particular neighboring base stations having high interference are identified based on the received interference information.
