Abstract: System(s) and method(s) are provided to facilitate generating and processing acquisition pilots in wireless communications. Acquisition pilots that convey timing and frequency synchronization information, wireless system acquisition and system determination information are modulated with pseudorandom sequences. The R bits of information carried by the acquisition pilot that conveys system determination information are augmented with T bits that convey a counter index associated with the system timing of superframes transmitted from an access point. The processing overhead resulting from the addition of the T bits is offset by the advantages afforded to a wireless communication. Salient advantages include: (i) processing gain at a receiver for communication in a specific sector during asynchronous operation, (ii) packet boundary determination through the counter field values, and (iii) initialization of various pseudorandom registers employed for communication.

Abstract: Systems and methodologies are described that provide half-duplex communication in a frequency division duplex (FDD) system. Communications in an FDD system may be divided into half-duplex interlaces, wherein a terminal may receive at one time period and transmit at another time period. An access network in an FDD system may then utilize half-duplex communication to communicate with an access terminal that is not capable of transmitting and receiving simultaneously by using a half-duplex interlace. Further, an access network may also utilize full-duplex communication to communicate with an access terminal that is capable of transmitting and receiving simultaneously.

Abstract: Systems and methodologies are described that provide techniques for generating and utilizing reverse link feedback for interference management in a wireless communication system. Other Sector Interference (OSI) indicators are transmitted from an interfering access point to an access terminal. At the access terminal, an appropriate delta value(s) is combined with the received OSI indicators. The combined information is transmitted to the access point in a feedback so the serving sector access point can analyze the amount of interference. Based on the provided feedback from the terminal, the serving sector access point can assign resources for use by the terminal in communication with the serving sector.
