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 facilitate soft handoff and enhanced performance in a wireless communication environment. In multiple access systems, access points assign certain resources (e.g., time, frequency, code) to each terminal. This assignment information can also be provided to neighboring sectors, allowing such sectors to receive and decode terminal transmissions. The information can be provided via backhaul signaling. Decoding by sectors within the active set of the terminal facilitates smooth transition as terminals move between sectors during soft handoff. In addition, sectors can signal successful receipt and decoding of transmissions, avoiding redundant processing.

Abstract:
A method and apparatus for generating erasure sequence in a wireless communication system is described. A one bit packet is constructed, wherein the bit in the packet is set to '0'. An initial seed of a scrambler using medium access control identity (MAC ID) of target access terminal and a packet format index of '0' is generated. A port counter i is initialized to '0'. A frame counter f is initialized to '0'. An orthogonal frequency division multiplexing (OFDM) symbol counter j is initialized to '0'. A set of usable hop-ports assigned to the packet in the f'th physical (PHY) Frame of transmission are arranged in increasing order. If nsc is not a pilot subcarrier is determined, wherein nsc is the subcarrier index corresponding to a hop-port pi in the j'th OFDM symbol in the PHY Frame.
