    Abstract: Techniques for sending control messages are described. In an aspect, assi gnment messages may be acknowledged based on either linked or dedicated ackn owledgement (ACK) resources. A terminal may receive an assignment message fr om a base station, determine whether to acknowledge the assignment message, and determine ACK resources to use to acknowledge the assignment message. Th e ACK resources may be linked to a control block on which the assignment mes sage was received, linked to resources given by the assignment message, or a ssigned to the terminal. The terminal may send the acknowledgement on the AC K resources. In another aspect, a control message may be acknowledged based on ACK resources determined based on the control message or the control bloc k. The ACK resources may be linked to resources assigned by the control mess age or linked to the control message. The terminal may send an acknowledgeme nt for the control message on the ACK resources.

    Abstract: Transmit and/or receive diversity is achieved using multiple antennas. In some embodiments, a single transmitter chain within a wireless terminal is coupled over time to a plurality of transmit antennas. At any given time, a controllable switching module couples the single transmitter chain to one the plurality of transmit antennas. Over time, the switching module couples the output signals from the single transmitter chain to different transmit antennas. Switching decisions are based upon predetermined information, dwell information, and/or channel condition feedback information. Switching is performed on some dwell and/or channel estimation boundaries. In some OFDM embodiments, each of multiple transmitter chains is coupled respectively to a different transmit antenna. Information to be transmitted is mapped to a plurality of tones. Different subsets of tones are formed for and transmitted through different transmit chain/antenna sets simultaneously. The balance of tones allocated to the subsets for each antenna are changed as a function of predetermined information, dwell information, and/or channel condition feedback information.

    Abstract: Methods and apparatus for collecting, measuring, reporting and/or using information which can be used for interference control purposes. Wireless terminals measure signals transmitted from one or more base stations, e.g., base station sector transmitters. The measured signals may be, e.g., beacon signals and/or pilot signals. From the measured signals, the wireless terminal generates one or more gain ratios which provide information about the relative gain of the communications channels from different base station sectors to the wireless terminal. This information represents interference information since it provides information about the signal interference that will be caused by transmissions from other base station sectors relative to transmissions made by the base station sector to which the wireless terminal is attached. Based on the signal energy measurements and relative gains generated from the energy measures, reports are generated in accordance with the invention and sent to one or more base stations.
