Patent ID: 8824968

Claim:
A method for reducing intercell interference in a wireless communication system, the method comprising: receiving, at a first user equipment from a first cell, scheduling information for transmission of a first signal to a second cell; and transmitting, at the first user equipment, the first signal to the second cell, wherein the first signal is generated by the first user equipment based on the scheduling information, wherein the scheduling information is provided by the first cell when uplink or downlink transmission of the first cell is interfered by uplink or downlink transmission of the second cell, wherein the first signal indicates a request to reduce downlink transmission power of the second cell or uplink transmission power of a second user equipment served by the second cell, wherein the scheduling information includes a grant for at least one candidate of a time and frequency resource region for transmitting the first signal, and wherein the at least one candidate of the time and frequency resource region for transmitting the first signal is predetermined and shared between the first and second cells.
