摘要： Techniques for deriving a high quality channel estimate are described. A first channel impulse response estimate (CIRE) having multiple channel taps is derived, e.g., by filtering initial CIREs obtained from a received pilot. A threshold parameter value is selected based on at least one criterion, which may relate to channel profile, operating SNR, number of channel taps, and so on. 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 may be determined, a threshold may be derived based on the average energy and the threshold parameter value, and channel taps with energy less than the threshold may be zeroed out. A memory may store threshold parameter values for different operating scenarios, and a stored value may be selected for use based on the current operating scenario.

摘要： A method and apparatus for channel estimation in a system employing differing transmission protocols as broadcast/multicast and unicast protocols. The number of pilot tones used for 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, since the pilots of the adjacent slots are used for the channel estimate. 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), and if a first symbol of the unicast slot. The pilot power or/and the number of the pilot sub-carriers is/are increased for the edge symbol of the multicast slot for purposes of channel estimation using the edge symbol.

摘要： Frame structures and transmission techniques for a wireless communication system are described. In one frame structure, a super-frame includes multiple outer-frames, and each outer-frame includes multiple frames, and each frame includes multiple time slots. The time slots in each super-frame are allocated for downlink and uplink and for different radio technologies (e.g., W-CDMA and OFDM) based on loading. Each physical channel is allocated at least one time slot in at least one frame of each outer-frame in the super-frame. An OFDM waveform is generated for each downlink OFDM slot and multiplexed onto the slot. A W-CDMA waveform is generated for each downlink W-CDMA slot and multiplexed onto the slot. A modulated signal is generated for the multiplexed W-CDMA and OFDM waveforms and transmitted on the downlink. Each physical channel is transmitted in bursts. The slot allocation and coding and modulation for each physical channel can change for each super-frame.

摘要： Systems and methods are disclosed that facilitate wireless communication using resource utilization messages (RUMs), in accordance with various aspects. 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.

摘要： Techniques are provided for association decisions by a user equipment (UE) or the like. In one example, there is provided a method that may involve discovering a peer UE, and determining a first metric for the peer UE. The method may further involve determining a second metric for a base station in a wireless area network (WAN). The method may further involve deciding whether to associate with the peer UE for peer-to-peer (P2P) communication or with the WAN for communication via the base station based on the first and second metrics. For example, the first metric may be determined based on received power of the peer UE at the first UE, and the second metric may be determined based on received power of the base station at the first UE.

摘要： An authorization scheme limits the number of nodes that send out resource utilization messages. Here, a first node may determine whether a second node is allowed to transmit a resource utilization message, and send a message to the second node indicative of this determination. The second node may then determine whether to send out a resource utilization message based on the message from the first node and the quality of service associated with receive traffic at the second node. In some aspects, a node that is allowed to transmit a RUM may be identified based on whether the node is expected to be scheduled to use a given resource.

摘要： Techniques for performing data detection and decoding in a manner to account for guard subbands are described. A receiver obtains received pilot symbols for pilot subbands and received data symbols for data subbands. Channel estimates are derived based on the received pilot symbols with zeroed-out pilot subbands filled with zeros. Data detection is performed on the received data symbols with the channel estimates to obtain data symbol estimates. Estimates of noise and estimation errors due to the zeroed-out pilot subbands are derived. LLRs are then computed based on the data symbol estimates, the channel estimates, and the estimates of the noise and estimation errors. The LLRs are deinterleaved and decoded to obtain decoded data.
