    摘要： Apparatuses and methodologies are described that coordinate multiple wireless communication protocols within a mobile device. A single mobile device can contain multiple communication components (e.g., a Bluetooth component, an IEEE 802.11b/g component). To prevent interference and possible loss of data, one communication component may be prevented from transmitting or receiving data packets while the other communication component is either transmitting or receiving. The components may be coordinated by a central controller located in the mobile device. Alternatively, the communication components may exchange messages to determine transmission or reception priority. In addition, one communication component may monitor the status of the other communication component to determine unused communication slots.

    摘要： Embodiments disclosed herein address the need in the art for enhanced block acknowledgement. In one embodiment, a receiver indicates a decoding delay for a maximum size aggregate frame in Block Ack negotiation, which may be used by a transmitter to determine to which Block Ack Request a Block Acknowledgement is responsive. In another embodiment, a Transmission Sequence Number (TSN) may be included in a Block Ack Request. The receiver includes the TSN in the corresponding Block Ack response. This allows the transmitter to determine which frames are “in transit.” The TSN may be used to identify blocks. In another embodiment, a TSN may be associated with one or more transmitted frames. While, the TSN is not transmitted with the Block Ack Request, the transmitter may determine which TSN corresponds with a Block Ack response in accordance with acknowledgements contained therein. Combinations of these techniques may be deployed. Various other aspects are also presented.

    摘要： Techniques for performing open-loop rate control in a TDD communication system are described. The channel quality of a first link is estimated based on a transmission received via the first link. The channel quality of a second link is estimated based on the estimated channel quality of the first link and an asymmetric parameter. At least one rate for a data transmission via the second link is selected based on the estimated channel quality of the second link. The estimated channel quality for each link may be given by a set of SNR estimates for a set of transmission channels on that link. The asymmetric parameter may be determined based on (1) the capabilities (e.g., transmit power, receiver noise figure, and number of antennas) of the transmitting and receiving stations or (2) received SNRs for the first and second links.

    摘要： A system and method for providing wireless time division multiplexed communications in which time is divided into a plurality of frames and each frame is divided into N data bursts, which has a first multiplexer defining a channel as a series of bursts that occur periodically every N bursts once per frame; a second multiplexer defining a sub-channel as every Mth burst of said channel; and a transmitter transmitting said channel and sub-channel from a first station to a second station. A new interleaving 0246/1357 method is used by the system which is just as good as the known 0123/4567 method when ideal frequency hopping is used, and 0246/1357 has better performance when non-ideal frequency hopping or no frequency hopping is used.

    摘要： Techniques for MAC processing for efficient use of high throughput systems that may be backward compatible with various types of legacy systems are disclosed. In one aspect, a data frame is formed comprising a common portion for transmission in a format receivable by various stations, such as access points and remote stations. The data frame also comprises a dedicated portion, formatted for transmission to a specified remote station. In another aspect, the common portion is unsteered, and the dedicated portion is steered. In another aspect, an access point schedules an allocation in response to a data indication included in a common portion of a data frame transmitted from one remote station to another. In another aspect, a first station transmits a reference to a second station, which measures the reference and generates feedback therefrom.
