摘要： A method provides access to a channel in a network including stations and an access point connected by a common wireless channel. A station makes a request to the access point to access to the channel to transmit a data stream. The access point assigns a sequence index value to the data stream. The sequence index value is broadcast by the access point. Then, the station transmits the data stream, during a contention free period, at a time corresponding to the sequence index value.

摘要： A system and method schedule series of packets for transmission between terminals in a single wireless channel of a packet-switched local area network. The local area network can operate in an ad hoc mode or in infrastructure mode. A transmission rate is assigned to each of the terminals. The terminals can be mobile. Different terminals can be assigned different transmission rates, depending on a quality of the channel. That is, terminals transmitting via an error-free channel are assigned a higher transmission rate than terminals transmitting via an error-prone channel. Then, the series of packets are scheduled for transmission between the terminals such that each terminal receives a substantially equal amount of transmission time over an extended period of time.

Plural consecutive packets, received at a station, include plural consecutive sounding packets. Each sounding packet corresponds to a different subset of the set of antennas, and at least one of the plural consecutive packets includes a high throughput (HT) control field including a signal to initiate antenna selection and a number N indicative of a number of sounding packets which follow the at least one packet including the HT control field and which are to be used for antenna selection. A channel matrix is estimated based on a characteristic of the channel as indicated by the received N sounding packets, and a subset of antennas is selected according to the channel matrix.

摘要： A method signals data in a channel of a network including multiple stations and an access point connected by a wireless channel. A station first requests access to the channel using a sequential coordinated channel access method of an access point. After the station receives permission to access the channel during a contention free period at a time corresponding to a sequence index value received by the station from the access point, the station transmits a resource request message to the access point to obtain a bandwidth allocation. In response, the station receives the bandwidth allocation, and the station can then transmit data during the contention free period according to the bandwidth allocation.

摘要： A method selectively acknowledges data packets in a network including a multiple stations connected by a common wireless channel. A transmitting station requests a block acknowledgement from a receiving station. The transmitting station transmits a block of data packets to the receiving station. The receiving station determines a number of successfully received data packets and a number of incorrectly received packets. Then, the receiving station selectively acknowledges only the successfully received data packets if the number of usefully received data packets is less than the number of incorrectly received data packets, and otherwise acknowledging only the incorrectly received packets.
