    Abstract: PROBLEM TO BE SOLVED: To achieve the inter-node fairness of wireless communication using resource utilization messages (RUMs), in accordance with various aspects.SOLUTION: A RUM may be generated for a first node, such as an access point or an access terminal, to indicate that a first predetermined threshold has been met or exceeded. The RUM may be weighted to indicate a degree to which a second predetermined threshold has been exceeded. The first and/or second predetermined thresholds may be associated with various parameters associated with the node, such as latency, throughput, data rate, spectral efficiency, carrier-to-interference ratio, interference-over-thermal level, etc. The RUM may then be transmitted to one or more other nodes to indicate a level of disadvantage experienced by the first node.

    Abstract: PROBLEM TO BE SOLVED: To provide a technique for deriving a high quality channel estimate.SOLUTION: A first channel impulse response estimate (CIRE) having multiple channel taps is derived by filtering initial CIREs obtained from a received pilot, for instance. A threshold parameter value is selected based on at least one criterion, and the criterion can relate to a channel profile, operating SNR, a number of channel taps, etc. A second CIRE is derived by zeroing out selected ones of the channel taps in the first CIRE based on the threshold parameter value. The average energy of the channel taps is determined, a threshold is derived based on the average energy and the threshold parameter value, and the channel taps with energy less than the threshold are zeroed out.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for channel estimation in a system employing differing transmission protocols as broadcast/multicast and unicast protocols.SOLUTION: The number of pilot tones used for a broadcast transmission is greater than the number of pilot tones used for a unicast transmission. The channel estimation may be significantly degraded when a symbol from a broadcast transmission slot is adjacent to a symbol from a unicast transmission slot. Therefore, it is determined whether a first time slot of one transmission protocol (multicast slot) is adjacent to a second time slot of another transmission protocol (unicast slot). The pilot power and/or the number of the pilot sub-carriers are/is increased for the edge symbol of the multicast slot for purposes of channel estimation using the edge symbol.

    Abstract: PROBLEM TO BE SOLVED: To provide distributed processing for a set of wireless communication devices to implement distributed, multi-antenna communication via one or more devices.SOLUTION: A relay link can be established between one or more wireless transceivers. The link can be utilized to distribute an indexing parameter to a remote transceiver. The indexing parameter can be employed to identify a set of index-specific instructions configured for a particular wireless node of a network. Based on the instructions and indexing parameter, such a transceiver can locally compute and transmit, or receive and decode, a stream of traffic data for multi-antenna communication. Thus, for instance, a P-P link between UTs can be employed to implement increased throughput and reduced interference benefits of multi-antenna communication for unplanned configurations of mobile devices.

    Abstract: Techniques to transmit data with cyclic delay diversity and pilot staggering are described. For cyclic delay diversity, OFDM symbols having different cyclic delay durations are generated. The cyclic 5 delay durations for the OFDM symbols may be selected to be time varying with respect to the cyclic delay durations for OFDM symbols transmitted by a neighboring base station. An FDM pilot is generated and multiplexed on multiple sets of subbands in different symbol periods. Waveforms for a second radio technology (e.g., W-CDMA) may be generated for data to be transmitted with this radio technology. The OFDM symbols are multiplexed onto time slots used for OFDM, and the 10 waveforms for the second radio technology are multiplexed onto time slots used for this radio technology. One or multiple modulated signals may be generated based on the multiplexed OFDM symbols and waveforms. Each modulated signal is transmitted from a respective antenna.
