摘要： A method and apparatus for measuring a channel quality in wireless transmit/receive units (WTRUs) which are equipped with a subscriber based smart antenna. The WTRUs are equipped with a smart antenna so that the WTRU generates a plurality of directional beams and, optionally, an omni-directional beam. A dwell time is provided in a measurement period to switch a beam from an active beam to a non-active beam. The active beam is one of the plurality of directional beams or, optionally, the omni-directional beam, for communication with one or more serving base station(s). A beam is switched to a non-active beam at the initiation of the dwell time. Signals are received through the switched non-active beam, and samples of the received signals are generated. The samples are stored in a memory. Channel quality is measured using the samples, whereby the dwell time to measure the channel quality is minimized.

摘要： A method and apparatus for transmit power control (TPC) while switching a beam among a plurality of beams in a wireless communication system. An antenna array generates a plurality of directional beams and preferably an omni-directional pattern and switches a beam among the plurality of beams preferably including the omni-directional pattern. Link quality on at least one of the plurality of beams is measured, and a beam having a greatest link quality is selected. If the selected beam is different from a current beam, a beam is switched from the current beam to the selected beam. While switching a beam, TPC parameters are adjusted based on the link quality difference between the link quality of the current beam and the link quality of the selected beam, and optionally, base on other parameters.

摘要： A method and apparatus for utilizing a switched beam directional antenna in a wireless transmit/receive unit (WTRU) is disclosed. A wireless communication system includes a serving cell, a neighbor cell and a WTRU. The WTRU is configured to generate and steer a directional beam in a plurality of directions. Once the WTRU registers with the wireless communication system, the WTRU receives messages transmitted by the serving cell. The WTRU measures signal quality of messages received in each of a plurality of predetermined directions while steering the directional beam antenna. The WTRU selects a particular one of the directions having the best signal quality. As the WTRU constantly moves, the WTRU monitors signal quality in the selected direction, and switches to another direction when the signal quality in a current direction drops below a predetermined threshold.

摘要： Multipoint wireless communications are coordinated in cells with radiation that is emanated from antennas in an inward direction. In an example embodiment, an apparatus includes a first antenna, a second antenna, a third antenna and a controller. The first antenna emanates radiation from a first location in an inwardly direction for a cell. The second antenna emanates radiation from a second location in an inwardly direction for the cell. The third antenna emanates radiation from a third location in an inwardly direction for the cell. The controller coordinates the emanation of the radiation via the first, second, and third antennas so as to reduce intra-cell interference for remote terminals located within the cell. The coordination may be effected in accordance with one or more coordinated multi-point (transmission/reception) (CoMP) techniques. Different numbers of sub-cells and antennas per cell and different CoMP cell organizations may be implemented.

摘要： Measurements for identifying pre-candidate cells are made by a wireless transmit/receive unit (WTRU) operating with a switched beam antenna in a wireless communication system. The switched beam antenna is a smart antenna generating a plurality of directional beams and an omni-directional beam. The WTRU measures signals from cells not in an active set of cells to define a pre-candidate set of cells. Measured signals from cells in the pre-candidate set of cells are compared to a threshold, and the corresponding cells are moved from the pre-candidate set of cells to a candidate set of cells based upon the comparison to the threshold. A measurement report is then sent to the network.
