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.

摘要： An aggressor base station (22-1) herein performs downlink interference coordination with one or more victim base stations (22-2, 22-3) in a radio communication network (10). Such coordination is performed for each of one or more iterations. For any given iteration, the aggressor (22-1) sends a message (28-2) to a victim (22-2) that indicates, for each of one or more downlink resources (26), whether the aggressor (22-1) promises to protect that resource (26) from interference by not transmitting on the resource (26) with a transmit power above a threshold (TH2). The victim (22-2) schedules downlink transmissions to one or more user equipments (16) on resources (26) that, according to the message (28-2), are protected from interference. Based on monitoring for interference to those transmissions, though, the victim (22-2) generates and sends to the aggressor (22-1) feedback (30-2) that generally requests an increase or decrease of the threshold (TH2). From evaluation of this feedback (30-2), the aggressor (22-1) determines a new threshold (TH2) on which promises are to be based in a message (28-2) to the victim (22-2) in a subsequent iteration.

摘要： An information processing apparatus and a communication apparatus for accurately recognizing, at the base station, the current receiving quality of the mobile terminals for improving the throughput of the base station. A mobile terminal determines its own receiving quality based on the signal received from the base station for generating the receiving quality message indicating the receiving quality and generates the power control information requesting the transmission power of the base station. The receiving quality message is transmitted at a frame rate and power control information is transmitted at the slot rate to the base station. Based on both the receiving quality message and power control information, the base station estimates the current receiving quality of the mobile terminal and adaptive modulation and coding is performed based on the estimated value.
