摘要： A station, such as a point coordinator (PC) or a non-PC station, in a basic service set (BSS) in a wireless local area network (WLAN) is disclosed. The station includes a frame classification entity (FCE), a frame scheduling entity (FSE) and a QoS management entity (QME). The FCE is logically located in a logical link control (LLC) layer of the station and has a classification table containing at least one classifier entry. Each classifier entry contains a virtual stream identifier (VSID) and a frame classifier associated with a user session. The FCE receives a data frame associated with the user session, which can be one of a voice session, a video session, a data session and a multimedia session. The data frame contains in-band quality of service (QoS) signaling information for the user session. The FCE classifies the received data frame to a selected VSID contained in a classifier entry in the classification table based on a match between an in-band frame classification information contained in the received frame and the frame classifier contained in the classifier entry. The FSE is logically located in a medium access control (MAC) sublayer of the station and has a frame scheduling table containing at least one entry. Each entry in the frame scheduling table contains a VSID and a QoS parameter set associated with a user session identified by the VSID. The FSE is responsive to the classified data frame by scheduling a transmission opportunity (TO) for the classified data frame based on the at least one QoS parameter value associated with the VSID and characterizing the user session. The QME interfaces with the FCE and The FSE.

摘要： A method and a system is disclosed for providing quality of service (QoS)-driven channel access within a basic service set (BSS) in a wireless local area network (WLAN). A contention control (CC) frame is sent from a point coordinator (PC) of the BSS during a contention-free period (CFP) of a superframe that includes the contention-free period (CFP) and a contention period (CP). The CC frame contains information relating to at least one of a priority limit for a next centralized contention interval (CCI), a length of the next CCI, a permission probability associated with the next CCI and information relating to a reservation request (RR) frame successfully received by the PC in a previous CCI. A non-colliding RR frame is then received at the PC in the CCI following the CC frame. The received RR frame is sent from a non-PC station in the BSS when at least one centralized contention opportunity (CCO) is available during the CCI after the CC frame. The RR frame indicates that the non-PC station sending the RR frame has at least one buffered data frame for transmission.

摘要： System and method for synchronizing clocks and maintaining packet timing relationships in a wireless communications system. A preferred embodiment further comprises periodically synchronizing local clocks at a transmitter and a receiver to a clock reference, adding a timestamp to each application packet at a transmitter of a wireless network, setting the timestamp to a value of a local time at the transmitter plus a link delay, buffering a received packet at a receiver, and releasing the buffered packet to an application level when a value of a local time at the receiver equals the timestamp value in the packet. This can help to ensure that the timing relationships between data packets present at a transmitter is maintained at a receiver, regardless of transport delays (waiting, transmission and processing) incurred by the data packets.

摘要： A retry algorithm determines the maximum number of transmissions and retransmissions that may be attempted for the frame in the head of a transmit queue or transmit buffer that needs to be transmitted across a communications link. The algorithm attempts to achieve a constant delay for each packet in frame by taking into account the number of frames residing in the transmit queue, the number of transmit opportunities elapsed between the arrivals of two successive frames in the transmit queue s, as well as the buffering capabilities of both the transmitting and receiving sides. The transmission and retransmission control technique provides for a way of managing the TX and RX buffers with a size that is suitable for the application being used and the underlying transport network. The number of retries is adapted to incoming and outgoing data rate changes in order to provide a fixed delay wireless link transport and maximize effective channel utilization.

摘要： A quality of service (QoS) station is disclosed containing a point coordinator (PC) for a basic service set (BSS) in a wireless LAN. The PC station includes a QoS management entity (QME) and an admission control entity (ACE). The QME receives at least one end-to-end QoS message that characterizes a user application, such as a voice call, a video call, a data call and a multimedia call. The at least one end-to-end QoS message includes at least one QoS parameter set that is expressed at layer 3 and higher of an ISO/IEC basic reference model of Open Systems interconnection (OSI) (ISO/IEC 7498-1) and is to be passed down to layer 2 of the PC-station for enabling QoS traffic transport of the application. The ACE performs an admission control decision relating to the application based on the at least one end-to-end QoS message characterizing the application. The ACE reserves a resource based on a QoS parameter set contained in the end-to-end QoS message. The ACE can be part of the QME and can include a resource control module that performs at least one admission control decision based on resource permission, and a policy control module that performs at least one admission control decision based on policy permission.

摘要： A method and a system for acquiring data frame timing in a discrete multitone modem system in which an acquisition frame is generated having a first predetermined number of impulse signals. Each impulse signal is spaced in time by 2(P+1)T.sub.s, such that 1/T.sub.s is a sample transmission rate, and P is a time length in samples of a cyclic prefix that is added to a data frame. The cyclic prefix length P is chosen such that a channel impulse response seen at a receiver effectively spans no more than P+1 samples when a received signal is sampled at the 1/T.sub.s rate. Data frames are generated subsequent to the acquisition frame. Each data frame includes a cyclic prefix and at least as many data samples as samples of the cyclic prefix. The acquisition and data frames are converted to an analog signal for transmission. The received acquisition frame is sampled and a summation window is advanced one sample at a time through the received acquisition frame. The sampled acquisition frame is summed over each summation window, with each summation window spanning P+1 samples of the acquisition frame. A maximum summation value is determined as the summation window advances, and a data frame boundary is determined based on the summation window corresponding to the maximum summation value. A channel impulse response is estimated based on the P+1 samples of the received acquisition frame corresponding to the maximum summation value, and data is coherently detected based on the estimated channel impulse response.

摘要： A system and method for establishing a pairwise temporal key (PTK) between two devices based on a shared master key and using a single message authentication codes (MAC) algorithm is disclosed. The devices use the shared master key to independently compute four MACs representing the desired PTK, a KCK, and a first and a second KMAC. The Responder sends its first KMAC to the Initiator, which retains the computed PTK only if it verifies that the received first KMAC equals its computed first KMAC and hence that the Responder indeed possesses the purportedly shared master key. The Initiator sends a third message including the second KMAC to the Responder. The Responder retains the computed PTK only if it has verified that the received second KMAC equals its computed second KMAC and hence that the Initiator indeed possesses the purportedly shared master key.
