    摘要: A method, an apparatus, and a computer program product operable in a wireless communication system are provided in which an access probe is generated for transmission to a wireless node. A first signal is generated for transmission to the wireless node. The first signal includes information corresponding to a first preferred beam pattern from the wireless node to the apparatus. A second signal is received from the wireless node including information corresponding to a second preferred beam pattern from the apparatus to the wireless node. The second preferred beam pattern is determined based on the access probe. The apparatus communicates with the wireless node using at least one of the first preferred beam pattern or the second preferred beam pattern.

    摘要: In a first aspect, an aggregated packet (A-MPDU) includes packets (MPDUs) and EC-Blocks (Error Correction Blocks) containing error correction coding information. A transmitter uses a Fountain coding scheme (for example, Raptor or RaptorQ) to generate the error correction coding information from the MPDUs. If a receiver detects an error in a received MPDU, then the receiver uses the error correction coding information from the EC-Blocks to correct the error. In a second novel aspect, a determination is made as to whether a change in error rate is more likely due to collisions or to a low SNR. If the determination is that the change is due to collisions then the MCS index is adjusted to restore a target error rate, whereas if the determination is that the change is due to a low SNR then the number of EC-Blocks per A-MPDU is adjusted to restore the target error rate.

    摘要: Various methods and apparatuses for transmitting an allocation of time in a wireless communication system are disclosed. In one aspect, an allocation of time for receiving communications via a receive beam direction is transmitted. The allocation of time may be based on information regarding an apparatus known to be located in the receive beam direction. A unique time for receiving communications from each known apparatus may be allocated, or a duration of time for receiving communications from the known apparatuses may vary based on a number of apparatuses known to located in a receive beam direction.

    摘要: A communication device for allocating tones is described that includes a processor and instructions in memory in electronic communication with the processor. The communication device determines whether a bandwidth for signal transmission is 20, 40, 80 or 160 megahertz (MHz). The communication device respectively allocates tones for 20, 40, 80 or 160 MHz as follows: for a very high throughput (VHT) signal A1 (VHT-SIG-A1): 52, 104, 208, 416; a VHT signal A2 (VHT-SIG-A2): 52, 104, 208, 416; a VHT short training field (VHT-STF): 12, 24, 48, 48; one or more VHT long training field(s) (VHT-LTF(s)): 56, 114, 242, 484; a VHT signal B (VHT-SIG-B): 56, 114, 242, 484; and a data field (DATA): 56, 114, 242, 484. The communication device also transmits the signal.

    摘要: Methods and apparatus are provided for performing and utilizing residual frequency offset estimation and correction in Institute of Electrical and Electronics Engineers (IEEE) 802.11 waveforms. Certain aspects of the present disclosure provide a technique for enabling one to perform good channel estimation with a signal-to-noise ratio (SNR)>33 dB, even in the presence of residual frequency errors. Further, certain aspects may enable one to support uplink Spatial Division Multiple Access (UL-SDMA), even in the presence of residual frequency offsets at the client side.
