摘要: Disclosed are a method and apparatus for transmitting a frame. A method for transmitting a frame in a wireless LAN comprises the steps of: an STA receiving an uplink transmission trigger frame from an access point (AP), wherein the uplink transmission trigger frame triggers the transmission of an uplink frame of an STA on an overlapping time resource, and triggers the transmission of one other uplink frame of at least one other STA; the STA transmitting the uplink frame to the access point (AP) through an allocated uplink transmission resource; and the STA performing a backoff process based on channel access parameters, which have been determined according to the success of the uplink frame transmission.

摘要: In an example of wireless communications, an access point (AP) may send a first trigger frame to multiple stations. In response, some or all of the stations may transmit their respective uplink frames to the AP. The uplink frames may include status information of the stations such as buffered data size. The AP may send a second trigger frame, including resource allocation assignments to inform stations which sub-bands may be used to send their payloads to the AP. The AP may allocate sub-bands to stations based on the status information of the station. The AP may allocate a relatively narrow sub-band to one or more stations when the status information is not known to the AP. Status information may be provided in certain control fields of a data frame. Random access may be provided by assigning a sub-band to multiple stations. Other methods, apparatus, and computer-readable media are also disclosed.

摘要: A packet collision among a plurality of access points is avoided and QoS is ensured. An access point that shares a wireless channel with a plurality of access points to carry out communication is provided with a function for determining, based on information contained in a polling communication signal or a broadcast signal transmitted from another access point, an access point (preceding AP) that is to perform polling communication immediately before the own station to form a group within which the order of the polling communication is determined, and after determining that a polling communication period of the preceding AP has ended, starting the polling communication period of the own station in a wireless network.

摘要: Methods and apparatuses for communicating in a wireless communication network are disclosed. For example, one method includes determining, by a first access point, a polling schedule for communicating with one or more wireless stations on a first wireless communication channel, the polling schedule for a second access point on a second wireless communication channel. The method further includes transmitting, by the first access point, on the first wireless communication channel, transmission information to the one or more wireless stations, wherein the transmission information comprises information for the one or more wireless stations to receive a transmission from the second access point on the second wireless communication channel. The method further includes transmitting, by the first access point, on the first wireless communication channel, one or more packets to at least one of the one or more wireless stations in accordance with the polling schedule.

摘要: Systems and methods for determining the health score of a Wi-Fi radio are described. Data associated with the Wi-Fi radio and/or an access point encapsulating the Wi-Fi radio may be received. Various parameters related to the Wi-Fi radio and/or an access point encapsulating the Wi-Fi radio may be determined. Weights may be assigned to the parameters, and the health score may be calculated using the weighted parameters. Default values may be assigned to the parameters if the initial determination of the parameter is below a minimal value. Configuration parameters related to the Wi-Fi radio, the access point, or neighboring access points may be transmitted based on the calculated health score.

摘要: Methodologies are presented that provide better uplink and downlink data throughput for cell-edge stations (CE STAs) in wireless networks. In downlink, two or more access points (AP) can work in concert to code a signal such that each AP sends a portion of the data during concurrent transmissions. To further enhance the data throughput of a CE STA, the channel access opportunities are increased. The CE STA is associated with multiple APs and installed with multiple low power receivers (LPRs) that are monitoring contiguous or non-contiguous channels. The CE STA can have LPRs monitoring each AP's operating channel. When an associated AP has a downlink data packet for the STA or can receive an uplink data transmission, the associated AP may send a low-power (LP) signal to the CE STA over the operating channel. Then, the CE STA can switch to that channel and trigger the downlink or uplink transmission.

摘要: Systems, methods, apparatuses, and computer program products for expediting repetition of an unanswered poll for automatic repeat request (ARQ) feedback are provided. One method includes transmitting a poll to a peer protocol entity to trigger status reporting at the peer protocol entity, starting a timer with a duration that is set based on whether at least one predefined condition is met. The at least one predefined condition depends at least on a value of a sequence number (SN) of a protocol data unit (PDU) in which the poll is transmitted. The method may further include re-transmitting a poll when the timer expires.
