    摘要: A method for wireless communications is disclosed that includes receiving a plurality of requests to transmit data from a plurality of apparatuses; determining resource allocation for a set of apparatuses in the plurality of apparatuses, wherein the determination is based on the plurality of requests; and transmitting a message comprising the resource allocation to the set of apparatuses to permit data transmission. Another method for wireless communications is disclosed that includes contending for access to a medium based on a request, by an apparatus, with a plurality of other apparatuses; receiving a message, the message comprising a resource allocation based on requests from the apparatus and the other apparatuses, wherein the resource allocation permits data transmission from the apparatus and some of the other apparatuses; and transmitting data by the apparatus based on the message. Apparatuses for performing the methods are also disclosed.

    摘要: Simultaneous, multi-user uplink communication is scheduled in a wireless network by transmitting a poll message to a plurality of access terminals in response to receiving a first request to transmit data via uplink. The poll message includes a solicitation for requests to transmit data from each of the plurality of access terminals. The poll message also includes a medium reservation and schedule for transmission of the requests from the access terminals. Based on the requests received from the access terminals, a number of the access terminals are selected for simultaneous transmission of data via uplink. A transmit start message is sent to each of the selected access terminals indicating when and for how long the selected access terminals may transmit data via uplink. After the data is received, a block ACK message is sent to each of the selected access terminals indicating successful simultaneous communication.

    摘要: A method includes sending a sequence number acknowledgement (SN-ACK) from a first device to a second device. The SN-ACK identifies a last consecutively correctly received data unit and includes a retry bit indicating whether at least one data unit of the plurality of data units was received by the first device subsequent to the last consecutively correctly received data unit. The method also includes, when the retry bit has a first value, sending a block acknowledgement (BA) after sending the SN-ACK. The BA includes a bitmap, where each particular bit of the bitmap indicates whether a corresponding data unit was correctly received. When the retry bit has a second value and one or more of the plurality of data units were incorrectly received by the first device, the first device receives a retransmission of one or more data units without sending the BA to the second device.

    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.
