Abstract: PROBLEM TO BE SOLVED: To provide an improved method for deploying small-coverage base stations.SOLUTION: An access point is configured based on acquired information. The access point may be configured based on configuration(s) of at least one other access point. An identifier to be transmitted by the access point may be selected based on identifier(s) transmitted by the at least one other access point. An access point may configure itself with assistance from a configuration server. For example, the access point may send information such as the location of the access point to the configuration server and the configuration server may respond with a list of neighboring access points for that access point. The configuration server may provide configuration information to an access point on the basis of the location of the access point. The configuration server also may direct an access point to a different configuration server.

Abstract: PROBLEM TO BE SOLVED: To provide methodologies that facilitate transmitting beacon symbols of a beacon message such that a sequence of symbols can satisfy a linear constraint over a field where the field elements can be identified with carriers.SOLUTION: A coding scheme can be applied to a beacon message; the coding scheme can produce a plurality of beacon symbols to transmit on given subcarriers. A receiving device of the beacon symbols decodes a beacon message by receiving less than the total number of symbols in a beacon message and determining the remaining symbol subcarriers based on the linear constraint. Thus, more efficient decoding of beacons is facilitated as well as resolving beacon ambiguity by figuring out which symbols satisfy linear constraints for the symbols, and resolving time and frequency shift by detecting an offset that would result in satisfaction of the linear constraint.

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 provide systems and methodologies that facilitate interference measurement and reporting in a network multiple-in-multiple-out (N-MIMO) communication system.SOLUTION: A network device can measure and report interference corresponding to network nodes other than a designated set of nodes. Interference reports can additionally identify dominant interfering nodes, correlation between transmit antennas of the respective nodes, or the like. The interference reports are combined with per-node channel information to manage coordination and scheduling across the respective network nodes. Interference from a network node can be measured by observing reference and/or synchronization signals from the network node. Each non-interfering network node can define null pilot intervals in which transmission is silenced or otherwise reduced. Loading information broadcasted by interfering network nodes can be identified and utilized in connection with interference calculation.

Abstract: PROBLEM TO BE SOLVED: To facilitate establishing a forward link acknowledgement channel and transmitting acknowledgment signals thereupon.SOLUTION: The signals are spread within contiguous channel clusters in a tile where the signals in the cluster are mutually orthogonal to one another. Additionally, the signals can be multiplexed over a plurality of frequency regions. In this regard, the acknowledgment signals are diverse with respect to frequency and interference; moreover, the signals can be received and decoded even where one of the channels experiences high interference. Furthermore, the acknowledgement signals can also communicate a channel deassign value, which provides diversity for devices to utilize persistent channels in communicating data to one another.

Abstract: PROBLEM TO BE SOLVED: To support communication avoiding interference in a heterogeneous network.SOLUTION: Communication in a dominant interference scenario is supported by reserving a plurality of subframes for a weaker base station observing high interference from a strong interfering base station. In another aspect, interference due to a first reference signal from a first station (for example, a base station) can be mitigated by canceling the interference at a second station (for example, UE) or by selecting a plurality of different resources for sending a second reference signal by the second station (for example, another base station) to avoid collision with the first reference signal. In another aspect, a relay transmits in an MBSFN mode in a plurality of subframes in which it listens to a macro base station, and in a regular mode in a plurality of subframes in which it transmits to a plurality of pieces of UE. In another aspect, a station transmits more TDM control symbols than a dominant interferer.

Abstract: PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate guard bandwidth independent mapping and de-mapping of bandwidth in a wireless communication system.SOLUTION: Broadcast signals can be created as if the whole bandwidth were available, and guard bandwidth can be initialized over the utilized bandwidth, to puncture data existing in the guard bandwidth. Upon decoding the broadcast signals, the size of the guard bandwidth can be predetermined or estimated by allowing a center portion of the signal to be decoded without decoding the guard bandwidth. In this regard, the decoder of the signal need not find exact positions of the guard bandwidth because transforming and decoding the center portion provides a substantial portion of the signal to interpret the signal.
