摘要： Techniques for performing interference and power control in a wireless communication system are described. An asymmetric power control scheme adjusts the transmit power of a user equipment (UE) in an asymmetric manner, e.g., with different up and down step sizes. In one design, a parameter value may be determined based on received SINR of at least one Node B. Up and down steps may be determined based on the parameter value and may have different sizes. At least one overloading indicator from at least one neighbor Node B may be obtained. The transmit power of the UE may be adjusted based on the up and down steps and the at least one overloading indicator. For example, the transmit power may be increased by the up step if an overloading indicator from the strongest neighbor Node B is not received and may be decreased by the down step otherwise.

摘要： A method for communicating in an advanced long term evolution (LTE-A) network using common reference signal (CRS) resources associated with different interference levels due to resource partitioning is disclosed. Signals are received from an eNodeB indicating a subset of CRS resources for radio link monitoring (RLM) and/or reference signal received power (RSRP) measuring. The subset of CRS resources includes the CRS resources expected to have lower interference from the interfering eNodeBs. RLM and/or RSRP measurements are performed based on the indicated subset.

摘要： A frontend receiver of a user equipment (UE) is configured with multiple transform operations assigned to separate sets of cells. One set of cells includes the serving cell of the UE and at least one additional cell within a first offset range of the serving cell. Another set or sets of cells include additional interferer cells within another offset range of the serving cell. After tracking the common frequency/timing offsets of each set of cells the assigned transform operation for that set transforms the time domain samples into frequency domain symbols. The individual frequency/timing offsets for each cell within the set are then tracked.

摘要： User equipment (UE) associated with synchronous networks operate in a synchronous mode while UEs associated with asynchronous networks operate in an asynchronous mode. When operating in a synchronous mode, a UE can significantly improve performance of synchronization signal detection, data decoding, and tracking loop management by using the interference cancellation (IC) techniques that are not available in an asynchronous mode of operation. Obtaining synchronization indicators and determining the synchronization status of the current network by UE is disclosed. The determination may be based on the synchronization indicator, whether detected through signal detection, signal measurements, signal analysis, or the like.

摘要： Techniques are described that provide inter-symbol interference—(ISI) and multi-user interference—(MUI) resilient blind timing synchronization and low complexity demodulation in wireless communication systems. A nonzero mean symbol is transmitted with a predetermined period in a stream of zero mean symbols during a synchronization phase. Only zero mean symbols are transmitted outside of the synchronization phase. Blind or non-data aided synchronization is performed at the receiver while bypassing channel estimation. The techniques enable timing synchronization via energy detection and low-complexity demodulation by matching the received waveform to a synchronized aggregate template (SAT). The SAT is recovered by averaging samples of the received waveform during the synchronization phase. In this manner, the described techniques may be applied to single or multi-user narrowband, wideband, or ultra-wideband (UWB) wireless communication systems with fixed or ad hoc access, but are particularly advantageous for wideband or UWB multi-user ad hoc access.

摘要： Methods and apparatus for selecting samples for secondary synchronization signal (SSS) detection are described. Several alternatives are provided for efficient cell identifier detection. In a first alternative, multiple bursts of a signal received from a cell are sampled with non-uniform spacing between sampling intervals to determine a sequence for cell identification. In a second alternative, samples of a first and a second signal received from a stronger cell are cancelled, and a sequence for detecting a weaker cell is determined by reducing effects of the samples of a third signal received from the weaker cell which do not overlap with the primary synchronization signal (PSS) or SSS of the stronger cell. In a third alternative, a sequence for detecting a weaker cell is determined by reducing effects of any sampled bursts that correspond to a high transmission power portion of a signal from a stronger cell.

摘要： Systems and methodologies are described that facilitate adjusting power spectrum density (PSD) for wireless devices according to multiple possible step sizes. A step size for an adjustment can be selected based at least in part on a received overload indicator from one or more access points, a PSD required to achieve a target signal-to-interference-and-noise ratio (SINR) for a wireless device, and a PSD previously assigned to the wireless device. Once the step size is selected, it can be applied to the previous PSD to generate a new PSD for the wireless device, and the wireless device can accordingly adjust PSD to mitigate inter-cell interference with the one or more access points.
