摘要： A method for uplink closed loop power control in advanced wireless systems which adaptively adjusts target signal-to-interference noise ratio (SINRtarget) in order to achieve the best uplink throughput of data services is disclosed. To derive the desired target SINR, the system collects and evaluates various uplink parameters as inputs: real-time signal-to-interference noise ratio of data physical channel, terminal power headroom, and terminal buffer data status and data service requirements.

摘要： A receiver receives signals and noise over a frequency spectrum of a desired received signal. The desired received signal is spread using code division multiple access. The received signals and noise are demodulated to produce a demodulated signal. The demodulated signal is despread using a code uncorrelated with a code associated with the desired received signal. A power level of the despread demodulated signal is measured as an estimate of the noise level of the frequency spectrum.

摘要： Methods and apparatuses are provided for uplink MIMO transmissions in a wireless communication system. In particular, a single inner loop power control may be utilized to control a power of both a primary stream and a secondary stream, in a system where the power of the secondary stream is linked to the power of the primary stream. That is, a single transmit power control command calculated according to the primary stream and directly controlling the power of the primary stream can effectively control the power of both uplink streams. Further, the disclosure provides outer loop power control, where a signal-to-interference ratio target used in the inner loop power control can be adjusted. Here, the SIR target may be adjusted in accordance with at least one of a block error rate performance or a HARQ failure performance of one of the primary stream or the secondary stream.

摘要： Techniques to increase the capacity of a W-CDMA wireless communications system. In an exemplary embodiment, early termination of one or more transport channels on a W-CDMA wireless communications link is provided. In particular, early decoding is performed on slots as they are received over the air, and techniques are described for signaling acknowledgment messages (ACK's) for one or more transport channels correctly decoded to terminate the transmission of those transport channels. The techniques may be applied to the transmission of voice signals using the adaptive multi-rate (AMR) codec. Further exemplary embodiments describe aspects to reduce the transmission power and rate of power control commands sent over the air, as well as aspects for applying tail-biting convolutional codes in the system.
