| 20090207762 | Assigning mobile users in a half-frequency division duplex (HFDD) system to uplink (UL) sub-frames and to downlink (DL) sub-frames - Methods assigning mobile users in a half-frequency division duplex (HFDD) system to a first UL group and second UL group of an uplink (UL) sub-frame, and to a first DL group and a second DL group of a downlink (DL) sub-frame, wherein the UL sub-frame is assigned a first carrier frequency and the DL sub-frame is assigned a second carrier frequency, are disclosed. One method includes determining a type of data, determining a receive CINR (carrier interference plus noise ratio), and determining a Doppler frequency parameter, for each mobile user of a plurality of mobile users. The plurality of mobile users to are assigned to the first UL group, the second UL group, the first DL group and the second DL group based on time durations of the first UL group, the second UL group, the first DL group and the second DL group, and based on and at least one of the data type, CINR, Doppler frequency spread of the mobile user, and a number of mobile users previously assigned to the first UL group, the second UL group, the first DL group and the second DL group. | 08-20-2009 |

| 20090092199 | Estimating frequency offset at a subscriber station receiver - A method and system of estimating frequency offset at a subscriber station is disclosed. One method includes the subscriber station receiving a composite signal, wherein the composite signal includes multi-carrier signals transmitted from a plurality of base stations. The subscriber station selects a first pair of multi-carrier symbols of the composite signal, wherein each multi-carrier symbol of the first pair of multi-carrier symbols includes a pilot sub-carrier having a common sub-carrier index. The subscriber station selects a second pair of multi-carrier symbols of the composite signal, the second pair having different symbol indices than the first pair, but having a same symbol index separation, wherein each of the multi-carrier symbols of the second pair of multi-carrier symbols includes a pilot sub-carrier having a second common sub-carrier index. The subscriber station estimates a phase based on a first sum of complex conjugate products between received symbols on the pilot sub-carriers of the first pair of multi-carrier symbols, and/or based on a second sum of complex conjugate products between received symbols on the pilot sub-carriers of the second pair of multi-carrier symbols. The subscriber station provides the phase to a filter of a frequency tracking loop of the subscriber station. | 04-09-2009 |
| 20090116575 | Method of a receiver estimating a plurality of channels - A method and apparatus of a receiver estimating a plurality of channels is disclosed. The method includes the receiver receiving a composite signal. The composite signal includes a signal from each of a plurality of transmission antennas, wherein the signal of each transmission antenna includes a delay relative to other signals of other antennas. The receiver estimates channels between the receiver and the plurality of transmission antennas based on amplitude and a phase of a received composite signal, at a plurality of frequencies. | 05-07-2009 |
| 20090190488 | Method of aiding uplink beamforming transmission - A method and apparatus of aiding uplink beamforming transmission is disclosed. One method includes a base station downlink transmitting beamformed signals to at least a first terminal, the beam formed signals directed and conveying data to at least the first terminal. The method further includes a second terminal eavesdropping the transmitted beamformed signals, and measuring a signal quality. The second terminal estimates uplink channel information based on the measured signal quality, for aiding uplink transmission. Based at least in part on the estimated transmission channel, the second terminal transmits beamformed uplink signals to the base station. | 07-30-2009 |
| 20090190520 | Method of updating transmission channel information based on eaves-dropping of beamformed signals - A method and apparatus of providing a base station with updated transmission channel information is disclosed. The method includes the base station transmitting beamformed signals to a first terminal. A second terminal receives the transmitted beamformed signals, and measures a signal quality. The second terminal conveys back to the base station the measured signal quality, and a transmission identifier of the beamformed data signal. | 07-30-2009 |
