An access point in a wireless network communicates with multiple mobile stations simultaneously using spatial-division multiple access.

Parallel wireless communication apparatus, method, and system

In one embodiment an controller comprises logic, at least partially including hardware logic, configured to logic, at least partially including hardware logic, configured to receive location data from a location measurement apparatus, buffer the location data in a local memory, and release the location data from the local memory to a remote processor in response to one or more trigger conditions. Other embodiments may be described.

GNSS services on low power hub

In one embodiment a controller comprises logic configured to receive, in the controller, a geofencing definition and input from at least one location information device, update a location of the controller using one or more location parameters from one or more location information devices, and generate a notification signal when the location of the controller indicates that the controller has crossed a threshold. Other embodiments may be described.

Geofencing techniques

Embodiments of a base station and method for resource allocation using localized and distributed resource blocks are generally described herein. The base station comprises processing circuitry to allocate localized resources to user stations based on receipt of channel quality information received from the user stations and to allocate distributed resource to user stations based on non-receipt of channel quality information. The base station also comprises physical layer circuitry to transmit control information on a physical channel to indicate the resources that are allocated to each scheduled user station.

Base station and method for resource allocation using localized and distributed resource blocks

Briefly, in accordance with one or more embodiments, a wireless signal is transmitted to a remote device. The remote device determines a precoding matrix indicator (PMI) in response to the wireless signal based at least in part on a hierarchical codebook. The PMI is then received as reported back from the remote device.

Multiple input, multiple output wireless communication system, associated methods and data structures

Briefly, in accordance with one or more embodiments, in response to receiving a wireless communication signal, a non-uniform codebook is generated based at least in part on one or more characteristics of the received wireless communication signal for quantization and communication back to a source of the received signal. The non-uniform codebook may be generated by selecting a suitable uniform codebook based at least in part on the one or more characteristics of the received wireless communication signal, and supplementing the uniform codebook with additional codewords to generate the non-uniform codebook.

An embodiment of the present invention provides a method, comprising optimizing the location and configuration of relay stations in a wireless network that includes at least one base station and at least one relay station by taking into account at least one or more of the following: the distinct antenna heights of said at least one base station and said at least one relay station; the data dependency between said at least one relay station and said at least one base station; the service outage of said wireless network; and the network throughput of said wireless network.

Techniques for optimal location and configuration of infrastructure relay nodes in wireless networks

An orthogonal-frequency division multiplexed (OFDM) transmitter is configured to transmit a data unit in accordance with a multiple-input multiple-output (MIMO) technique over a wideband channel comprising a 20 MHz channel and another channel using a plurality of spatially diverse antennas. The transmitter is further configured to include in the data unit, a parameter indicating a modulation and coding scheme and a parameter indicating number of spatial streams. Each of the spatial streams is encoded and beamformed for receipt by one or more different receiving stations.

MIMO transmitter and method for transmitting OFDM symbols

Methods and apparatuses for providing CQI feedback with common code rate to a transmitter station are described herein. In one implementation, the methods may include a receiver station that is communicatively linked to a transmitter station via k spatial channels transmitting a first CQI to the transmitter station that indicates a modulation level for use by the transmitter station to transmit (i.e., to configure for transmission) a first of k streams of signals to be transmitted to the receiver station. The first CQI may further include a common code rate to be used by the transmitter station for transmitting the first of the k streams of signals as well as for transmitting the rest of the k&#x2212;1 additional streams of signals to the receiver station. The receiver station may further transmit to the transmitter station k&#x2212;1 additional CQIs to indicate to the transmitter station the k&#x2212;1 modulation levels to be used by the transmitter station for transmitting the k&#x2212;1 additional streams of signals to the receiver station.

Providing CQI feedback with common code rate to a transmitter station

Methods and apparatuses for providing CQI feedback to a transmitter station are described herein. In one implementation, an apparatus may include a transceiver to transmit and receive signals to and from a transmitter station, and a controller coupled to the transceiver to control the transceiver to transmit to the transmitter station a first channel quality indicator (CQI) that corresponds to a first modulation level to be used by the transmitter station to transmit first signals, and to control the transceiver to transmit to the transmitter station a differential indicator that comprises two bits or less to differentially indicate a second CQI relative to the first CQI, wherein the second CQI corresponds to a second modulation level to be used by the transmitter station to transmit second signals. Other embodiments may be described and/or claimed.

Embodiments of the present invention provide for downlink resource allocation among a plurality of users. Other embodiments may be described and claimed.

Downlink resource allocation and mapping

A MIMO transmitter and method for transmitting a group of sequential OFDM symbols on a downlink channel using a plurality of antennas is disclosed herein. Groups of OFDM subcarriers are individually modulated in accordance with spatial-frequency subcarrier modulation assignments to generate groups of symbol-modulated subcarriers, corresponding symbol-modulated subcarriers are combined for transmission on each of a plurality of spatial channels, and beamforming is performed on the combined symbol-modulated subcarriers for transmission over the spatial channels. The channel comprises a plurality of the groups of the OFDM subcarriers and the OFDM subcarriers within each group of subcarriers and within each group of sequential OFDM symbols have the same spatial-frequency subcarrier modulation assignments. The spatial-frequency subcarrier modulation assignments for each group are determined based on feedback by a receiver, which is determined from spatial channel characteristics of the spatial channels.
