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: Signals from antennas A and B are alternately switched by an antenna switch at a predetermined rate. Then, the signals from the antennas A and B are alternately input to a wireless receiving unit. The wireless receiving unit orthogonal-signal-detects the signals received by the antennas A and B, and inputs the detected signals to a branch selecting unit. The branch selecting unit extracts only the signals from either of the antennas from the signals obtained from the antennas A and B, which are alternately arranged in time series, and transmits the extracted signals to a matched filter. A searcher obtains despreading timings from correlation values, and stores the obtained timings in two memories. The searcher obtains despreading timings with large correlation values, and transmits the timings to a despreading unit to perform RAKE reception.

Abstract: An antenna apparatus for a folder type mobile phone, wherein a first antenna is installed in a main body of the folder type mobile phone, and a second antenna is installed in the folder. The folder type mobile phone installs a main antenna apparatus in the main body, and an antenna apparatus for maximizing the diversity effect in the folder. As a result, it becomes more convenient to carry the folder type mobile phone based on the diversity mode, while securing a broader separation distance between two antennas at the same time.

Abstract: A method and system for conducting rapid control traffic in a time division multiple access (TDMA) communication system comprises a base station communicating with a plurality of user stations in assigned time slots of a time frame. For bearer traffic, time slots are assigned to particular user stations for an extended duration. In unassigned time slots, the base station transmits a general polling message indicating availability of the time slot. A user station desiring to hand off communication from one base station to another uses multiple available time slots at the target base station for exchanging control traffic messages with the target base station. The next available time slot is indicated by a slot pointer in the header of each general polling message to facilitate rapid exchange of control traffic messages. During handover, the user station may establish a new link with the target base station before relinquishing the existing communication link with the old base station.
