  • Patent number: 8102832
    Abstract: Techniques are provided to support fast frequency hopping with a code division multiplexed (CDM) pilot in a multi-carrier communication system (e.g., an OFDMA system). Each transmitter (e.g., each terminal) in the system transmits a wideband pilot on all subbands to allow a receiver (e.g., a base station) to estimate the entire channel response at the same time. The wideband pilot for each transmitter may be generated using direct sequence spread spectrum processing and based on a pseudo-random number (PN) code assigned to that transmitter. This allows the receiver to individually identify and recover multiple wideband pilots transmitted concurrently by multiple transmitters. For a time division multiplexed (TDM)/CDM pilot transmission scheme, each transmitter transmits the wideband pilot in bursts. For a continuous CDM pilot transmission scheme, each transmitter continuously transmits the wideband pilot, albeit at a low transmit power level.

  • Patent number: 8085831
    Abstract: Inter-sector interference for a target user in a sector may be controlled by selectively blanking or attenuating transmit powers for interfering users in neighboring sectors whenever their transmissions collide. The sector provides the frequency hopping (FH) sequence or subband usage for the target user to the neighboring sectors. Each neighboring sector uses the target user's FH sequence to form a blanking pattern. Each neighboring sector then either blanks or reduces transmit power for each subband in its blanking pattern. Each user in each neighboring sector receives either (1) punctured symbols for subbands in the blanking pattern, if blanking is performed, or (2) lower energy symbols for these subbands, if attenuation is performed. In any case, the target user and each neighboring user may process their received symbols in the normal manner and do not need to be informed of the blanking/attenuation.

  • Patent number: 8059589
    Abstract: Systems and methodologies are described that facilitate dynamically scheduling orthogonal resource sets for reuse by user devices to reduce inter-cell interference by evaluating an overall scheduling metric for each user device in a wireless communication region. The overall scheduling metric can be evaluated by determining a fairness metric for each user device in a wireless communication region, an overall channel peak desirability metric for each user device, and a channel delay desirability metric for each user device. The overall scheduling metric can be the function of the fairness metric and one or more of the overall channel peak desirability metric and the channel delay desirability metric. A user device with a highest overall scheduling metric score for a given round of dynamic scheduling can be awarded an orthogonal resource set.

  • Patent number: 7990911
    Abstract: A method and apparatus to determine whether a transmission was successfully received in a multiple access communication system is claimed. First and second encoded data packets are received and decoded. The first and second data packets are then re-encoded, and correlated to determine whether the first and second re-encoded data packets are the same. If there is a high degree of correlation, an indicator of acknowledgement is transmitted to indicate that there is a high degree of correlation between the first and second re-encoded data packets. If there is a low degree of correlation, a determination is made that the previously transmitted indicator of acknowledgement was correctly received.

  • Patent number: 7983674
    Abstract: Techniques for selecting a reverse link (RL) serving base station for a terminal are described. The terminal sends a transmission on the reverse link to multiple base stations in a wireless communication system. The transmission may be for signaling sent on a control channel. The terminal receives feedback (e.g., power control (PC) commands and/or erasure indications) from the multiple base stations. Each base station may generate feedback based on the control channel and/or some other transmission received from the terminal. The terminal performs reverse link power control and further selects an RL serving base station based on the received feedback. For example, the terminal may select the base station with the lowest transmit power level, the largest percentage of power down commands, or the lowest erasure rate as the RL serving base station.

  • Publication number: 20110053558
    Abstract: A method, system and devices for enabling secure pairing between two communication devices equipped with a minimal user interface includes determining a verification pattern based upon security information exchanged between the two communication devices and presenting the verification pattern in a manner that can be perceived by a user who can determine whether the verification patterns are the same. The verification patterns may be presented as flashing light displays, such as flashing sequences of a light emitting diode, or as sounds, such as tones or click patterns emitted by a speaker. If a user perceives that the verification patterns emitted by both communication devices are the same, the user may so indicate by pressing a button on each of the devices. Obtaining such user confirmation of the verification patterns enables establishing a secure pairing between the two communication devices that is protected from active and passive eavesdropping.
