    Abstract: Methods and devices for operating a wireless communication device that can communicate with at least two different co-located APs are described. The device may receive, from a first AP, information corresponding to a second AP of the co-located APs. The information corresponding to the second AP may include state information of the second AP. The device may establish a first wireless link with the first AP using a first frequency of the first AP and establish a second wireless link with the second AP using a second frequency which is different than the first frequency. The device may simultaneously receive first data from the first AP and second data from the second AP.

    Abstract: Methods and apparatus for communicating and utilizing persistent allocation of resources are described herein. A base station may allocate persistent resources to a client station, and may associate the client station or persistent resource allocation with a particular shared NACK channel. The base station may monitor the NACK channel for a NACK indicating a map error. The base station may monitor the resource allocation to implicitly determine a map error. The base station may resend one or more persistent resource allocation information elements in response to the NACK or implicit error determination. A client station having a persistent resource allocation may monitor persistent resource allocation information elements in map messages and/or may indicate failure to receive a persistent resource allocation information element in a NACK message on a shared NACK channel.

    Abstract: A method of wireless communication including a base station transmitting a preamble including information indicating a sector identifier and an antenna port value. The base station further transmits a pilot sequence, wherein the pilot sequence and the location of the pilot sequence are based on the sector identifier and on the antenna port value. A base station configured to perform the method is also disclosed. A corresponding subscriber station configured to receive the preamble and pilot sequence is also disclosed, as well as a subscriber station method.

    Abstract: A method of transmission over multiple wireless channels in a multiple antenna system includes storing channel modulation matrices at a transmitter; receiving quantized channel state information at the transmitter from plural receivers; selecting a transmission modulation matrix using the quantized channel state information from the stored channel modulation matrices; and transmitting over the multiple channels to the plural receivers using the selected transmission modulation matrix. In another embodiment, the method includes storing, at one or more receivers, indexes of modulation matrices generated by a capacity enhancing algorithm; upon a selected one of the one or more receivers receiving a transmission from the transmitter, the selected receiver selecting a modulation matrix from the stored modulation matrices that optimizes transmission between the transmitter and the selected receiver; the selected receiver sending an index representing the selected modulation matrix; and receiving the index at the transmitter from the selected receiver.
