    Abstract: PROBLEM TO BE SOLVED: To provide a method for receiving packets via H-ARQ transmissions with interference cancellation in a quasi-orthogonal communication system.SOLUTION: To receive packets with interference cancellation, block transmissions for the packets are received on time-frequency blocks used by these packets. Receiver spatial processing is performed on input symbols to obtain detected symbols. For each packet that is decoded correctly, the transmission for the packet is terminated, and the interference due to the packet is estimated. Receiver spatial processing is performed on the interference-canceled symbols to obtain new detected symbols for all time-frequency blocks used by all correctly decoded packets. Each packet decoded in error and overlapping at least partially with any correctly decoded packet may be demodulated and decoded based on all detected symbols available for that packet.

    Abstract: PROBLEM TO BE SOLVED: To provide techniques to more efficiently transmit pilots on demand on a reverse link.SOLUTION: Pilots are transmitted on demand on a reverse link and used for channel estimation and data transmission on a forward link. A base station selects at least one terminal for on-demand pilot transmission on the reverse link (210). Each of the at least one selected terminal is a candidate for receiving data transmission on the forward link. The base station assigns each of the at least one selected terminal with a time-frequency allocation (212), which may be for a wideband pilot, a narrowband pilot, or some other type of pilot. The base station receives and processes an on-demand pilot transmitted from each of the at least one selected terminal (216) and derives a channel estimate for the terminal based on the received pilot (218).

    Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and method for increasing system capacity in a multi-access wireless communication system. SOLUTION: Spatial dimensions are utilized to distinguish between multiple signals utilizing the same channel and thereby increasing system capacity. Signals may be separated by applying beamforming weights based upon the spatial signature of a pair of a user device 104 and a base station 102. Grouping spatially orthogonal or disparate user devices on the same channel facilitates separation of signals and maximization of user device throughput performance. User devices may be reassigned to groups periodically or based upon changes in the spatial relationships between the user devices and the base station. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To efficiently provide scheduling information from an access terminal to a base station to enable effectuating scheduling decisions.
    SOLUTION: The access terminals may transmit scheduling information to a base station in bifurcated requests. The access terminals transmit coarse scheduling information to the base station by utilizing a dedicated out-of-band channel. The base station carries out allocation corresponding to the coarse scheduling information. The access terminals transmit fine scheduling information to the base station over an in-band channel in accordance with the allocation.

    Abstract: PROBLEM TO BE SOLVED: To provide a technique to support simultaneous transmission for more terminals in a multiple access system. SOLUTION: In a single-carrier frequency division multiple access (SC-FDMA) system that utilizes interleaved FDMA (IFDMA) or localized FDMA, a multitude of transmitters transmit their pilots which are orthogonal to one another using time division multiplexing (TDM), code division multiplexing (CDM), interleaved frequency division multiplexing (IFDM), or localized frequency division multiplexing (LFDMA). A receiver performs complementary demultiplexing (non-multiplexing) on the pilots and derives a channel estimate associated with each transmitter using an MMSE technique or a least-squares technique. The receiver separates data transmissions sent on the same time-frequency block through the use of spatial filter matrices. The receiver derives the spatial filter matrices based on the channel estimates and using also a zero-forcing, MMSE, or maximal ratio combining technique. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To increase system capacity in a code-limited WCDMA(R) (e.g., TDD, FDD, ...) wireless communication environment.SOLUTION: A larger code space can be defined by introducing multiple code clusters within a sector, where each cluster has a unique scrambling code. Codes within a cluster have orthogonal Walsh sequences that can be assigned to user devices to facilitate communicating over a wireless network and can overlap with codes in another cluster. The unique scrambling code assigned to each cluster can ensure that duplicate Walsh sequences in another cluster in the same sector appear as pseudo-noise codes.

    Abstract: PROBLEM TO BE SOLVED: To provide systems and methods that facilitate providing time-division duplexed beam-forming support in traditional non-time-division duplexed wireless systems, such as an OFDMA system, a WCDMA(R) system, etc.SOLUTION: A base station analyzes pilot information, such as a portion of bandwidth over which a user device is transmitting (402), and transmits on a downlink using a pre-hopped portion of bandwidth utilized by the user device on the preceding reverse link time slot (404). The base station then transmits bandwidth segment reassignment to the user device to facilitate bandwidth segment hopping between user devices served by the base station (406). Additionally, the base station can instruct the user device to provide on-demand pilot information to resolve ambiguity related thereto.
