METHOD AND APPARATUS FOR COEXISTENCE AMONG WIRELESS TRANSMIT/RECEIVE UNITS (WTRUS) OPERATING IN THE SAME SPECTRUM
First Claim
1. A wireless transmit/receive unit (WTRU) comprising:
- a memory configured to store a plurality of coexistence gap patterns, each of the plurality of coexistence gap patterns defining a pattern of transmission periods and silent periods for the WTRU and corresponding to a respective duty cycle of a plurality of duty cycles;
a receive unit configured to receive from a base station information regarding a duty cycle for a wireless cell operated by the base station;
a transmit unit configured to transmit information; and
a control unit configured to select one of the plurality of coexistence gap patterns based on the received information regarding the duty cycle for the wireless cell and control the transmit unit to transmit information during the transmission periods and not transmit information during the silent periods of the selected one of the plurality of coexistence gap patterns.

Abstract
A method and apparatus for coexistence among wireless transmit/receive units (WTRUs) operating in the same spectrum are disclosed. A WTRU includes a memory, a receive unit, a transmit unit and a control unit. The memory stores coexistence gap patterns. Each of the coexistence gap patterns defines a pattern of transmission periods and silent periods for the WTRU and corresponds to a respective duty cycle. The receive unit receives from a base station information regarding a duty cycle for a wireless cell operated by the base station. The control unit selects one of the coexistence gap patterns based on the received information regarding the duty cycle for the wireless cell and controls the transmit unit to transmit information during the transmission periods and not transmit information during the silent periods of the selected one of the plurality of coexistence gap patterns.
