Abstract: A sequence of codes are provided for potential assignment to a user in a wireless hybrid time division multiple access (TDMA)/code division multiple access (CDMA) communication system. At least one timeslot is selected to support the communication. For each selected timeslot, at least one code is selected. If more than one code is selected, the selected codes are consecutive in the provided codes sequence. For at least one of the selected timeslots, an identifier of a first and last code of the selected consecutive codes is signaled. The user receives the signaled identifier and uses the selected consecutive codes, as identified, to support the communication.

Abstract: A wireless communication method and antenna system for determining the direction of arrival (DOA) of received signals in azimuth and elevation, (i.e., in three dimensions), to form a beam for transmitting and receiving signals. The system includes two antenna arrays, each having a plurality of antenna elements, two first stage multi-mode-port matrices, at least one second stage multi-mode-port matrix, an azimuth phase detector, an elevation amplitude detector, a plurality of phase shifters and a transceiver. The antenna arrays and the first stage multi-mode-port matrices form a plurality of orthogonal omni-directional modes. Each of the modes has a characteristic phase set. Two of the modes' phases are used to determine DOA in azimuth. The second stage multi-mode-port matrix forms a sum-mode and a difference-mode used to determine the DOA of the received signals in elevation. A beam is formed in the direction of the received signals by adjusting the phase shifters.

Abstract: Systems and methods for optimizing the efficiency of each of a plurality of power amplifiers that amplify a corresponding one of a plurality of radio frequency signals for transmission by a corresponding one of a plurality of antennas. Using transmit beamforming, the power of each amplified signal output by the power amplifiers may not be the same for all the power amplifiers, and may vary with changes in the communication channel between the transmitting device and receiving device. Each of the plurality of power amplifiers is controlled to operate with one or more operating parameters that optimize the efficiency for an output power level of corresponding ones of the radio frequency signals. By adjusting one or more operating parameters of each power amplifier according to changing requirements (e.g., the destination device and channel conditions), the efficiency of each power amplifier can be optimized.

Abstract: A transmission power level for a user equipment in a wireless time division duplex communication system using code division multiple access is determined. An interference level is measured. A pathloss estimate is determined. A long term average of pathloss estimates is determined. A first weighting factor, ?, is determined by the determined pathloss estimate, producing a weighted pathloss estimate. (1??) is multiplied to the determined long term average of pathloss estimates, producing a weighted long term pathloss estimate. A target signal to interference ratio is provided. The target signal to interference ratio is updated using outer loop power commands. A transmission power level of the user equipment is determined by adding the weighted pathloss estimate to the weighted long term pathloss estimate to the measured interference level to the updated target signal to interference ratio to a constant value.

Abstract: Resource units are assigned within a cell of a wireless time division duplex communication system using code division multiple access. Each resource units is associated with a time slot and a code. For selected ones of the cell's resource units, the code interference level is measured during that unit's time slot and using that unit's code. The code interference level is compared to a threshold to determine whether that unit has an acceptable code interference level. Resource units are assigned to communications out of the unit's having acceptable interference levels.

Abstract: Vertical electromagnetic stirring is used to produce low shear, stress, turbulent and chaotic mixing of a liquid material or suspension in a container regardless of the volume or container geometry. Movement of a magnetic stir bar is controlled by multiple magnetic fields. The magnetic fields are produced by a series of sequentially or non-sequentially activated inductor coils which produce asymmetrical stirring dynamics and random motions of the stir bar, causing the liquid material to be gently and effectively mixed throughout the container. Moving the stir bar in random and irregular patterns during the stirring operation creates turbulent and chaotic mixing dynamics. The stir bars used for supporting vertical magnetic stirring are specifically designed to optimize the effectivity of the mixing process by maximizing the length of the stir bar to quickly and gently mix the materials.
