    Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for a quick retransmission of signals in a communication system.SOLUTION: A transmitting terminal, transmits transmission signals in a form of packets to a receiving terminal, if the packet was intended for the receiving terminal, and the receiving terminal demodulates the packet. The receiving terminal then computes a quality metric of the packet, and compares the computed quality metric with a quality metric contained in the packet. If the quality metrics match, the packet is forwarded for further processing. If the quality metrics fail to match, the receiving terminal sends a request for retransmission of the packet. The transmitting terminal determines which packet needs to be retransmitted based on the request for retransmission. If delivery of the packet in accordance with the aforementioned description fails, retransmission in accordance with conventional sequence-number-based schemes, e.g., radio link protocol, is attempted.

    Abstract: PROBLEM TO BE SOLVED: To increase the throughput in a sector.SOLUTION: Upon successful decoding of a first set of slots of a first data packet, an access network (AN) can send an acknowledge message (ACK) to an access terminal (AT) to indicate that the AN has successfully decoded the data received in the first set of slots of the first data packet. Upon unsuccessful decoding of the first set of slots of the first data packet, the AN can send a negative acknowledge message (NAK) to the AT to indicate that the AN has not successfully decoded the data received in the first set of slots of the first data packet. Based upon receipt of the NAK, the AT can resend the data by sending a second set of slots of the first data packet containing redundant data. Based upon receipt of the ACK, the AT can send a first set of slots of another packet.

    Abstract: PROBLEM TO BE SOLVED: To provide methods and systems for providing enhanced position location in wireless communications.SOLUTION: Embodiments disclosed herein relate to methods and systems for providing improved position-location (e.g., time-of-arrival) measurement and enhanced position location in wireless communication systems. In an embodiment, an access point may replace information (e.g., data) transmission by a "known" transmission (or "reference transmission") at a predetermined time known to access terminals in the corresponding sectors. The access terminals may use the received reference signal to perform a position-location measurement, and report back the measured information. The access point may also send a reference transmission on demand, e.g., in response to a request from an access terminal in need of a location-based service.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for tracking signals in a wireless communication system.SOLUTION: A base station includes a rake antenna having multiple fingers. When any of the fingers goes out of lock, the base station waits for a predetermined time period and then adjusts a lock detect filter. The adjustment is based on comparison of received signal energy with an adjusted energy threshold. The comparison may result in an increased energy level of the filter. In one embodiment, if a mobile station is in soft hand-off, the base station ignores the lock state of the fingers and transmits power control information based on the received signal energy. If the mobile station is not in soft hand-off, a predetermined power control pattern is applied for gradual power adjustment.
