摘要： Aspects describe controlling a power level for an access terminal in a wireless communication system that utilizes multiple modulation waveforms. The power can be controlled after an Access Grant is received in response to an Access Probe until the mobile device transitions into a steady state. A reference power can be continuously monitored and a setting of a power amplifier can be modified only when the reference power changes. A digital gain of a reverse data channel can be adjusted relative to the reference power level.

摘要： Systems and methodologies are described that facilitate increasing system capacity in a code-limited WCDMA (e.g., TDD, FDD, . . . ) wireless communication environment. According to one aspect, a larger code space can be defined by introducing multiple code clusters within a sector, wherein each cluster has a unique scrambling code. Codes within a cluster can have orthogonal Walsh sequences that can be assigned to user devices to facilitate communicating over a wireless network and can overlap with codes in another cluster. The unique scrambling code assigned to each cluster can ensure that duplicate Walsh sequences in another cluster in the same sector appear as a pseudo-noise codes.

摘要： A method for estimating a feedback channel for a wireless repeater uses frequency domain channel estimation and uses a signal indicative of the amplified signal as a pilot signal. The channel estimation method generates a time domain feedback channel estimate from the frequency domain channel estimation and scales the time domain feedback channel estimate using scaling factors. In one embodiment, the scaling factors are function of a tap index and the block size of the frequency domain channel estimation.

摘要： At a mobile device, a total received power represents signals received from all access points. In order to calculate an appropriate transmit power for communication with a single access point, a mobile device determines a per sector received power level. The mobile device can ascertain a time-domain channel response from each access point pilot signal, ascertain a received digital power lever per sector from each access point pilot signal and, based in part on the digital power level, calculate a received power level from each access point. A per sector received power level can be utilized to conserve battery power and/or to reduce interference in a wireless communications network.

摘要： Transmission schemes that can flexibly achieve the desired spatial multiplexing order, spatial diversity order, and channel estimation overhead order are described. For data transmission, the assigned subcarriers and spatial multiplexing order (M) for a receiver are determined, where M≧1. For each assigned subcarrier, M virtual antennas are selected from among V virtual antennas formed with V columns of an orthonormal matrix, where V≧M. V may be selected to achieve the desired spatial diversity order and channel estimation overhead order. Output symbols are mapped to the M virtual antennas selected for each assigned subcarrier by applying the orthonormal matrix. Pilot symbols are also mapped to the V virtual antennas. The mapped symbols are provided for transmission from T transmit antennas, where T≧V. Transmission symbols are generated for the mapped symbols, e.g., based on OFDM or SC-FDMA. Different cyclic delays may be applied for the T transmit antennas to improve diversity.

摘要： Methods and apparatus for estimating a loop delay value (Ndelay) in an interference cancellation repeater are presented. For example, a method may include setting a repeater gain to an initial gain value, setting a delay parameter to an initial time value, and measuring a loop gain associated with the delay parameter and the repeater gain by detecting a feedback signal with an echo canceller disabled. The method may further include determining whether the measured loop gain is larger than a previously measured loop gain, and if so, designating the delay parameter as the loop delay value (Ndelay); and decrementing the delay parameter when the measured loop gain is not larger than the previously measured loop gain, and when the delay parameter is not at a final time value. The method may iterate until the delay parameter is less than or equal to the final time value.
