摘要： A wireless communication network uses backhaul negotiation based upon static and dynamic resource assignment on jamming graphs. Static reuse factor design methods including fractional frequency reuse (FFR) are addressed. The jamming graph is used to summarize the interfering relationship between transmitters (nodes in the jamming graph). Negotiation-based algorithm is used to arrive at a static resource assignment so that a large reuse factor can be achieved while jamming scenario can be avoided. As a result of such algorithm, each transmitter is assigned some resources, over which traffic transmission can be done instantaneously to reduce the packet delay for short packets. Based on the result of static resource negotiation algorithm, a dynamic resource algorithm can be run, such that the resources assigned to different nodes can be share in a bursty traffic scenario to further reduce packet delay for larger packet size cases, while jamming be also avoided.

摘要： Systems and methodologies are described that facilitate defining new control channels in legacy wireless networks. Control data resources for new systems can be defined over resources reserved for general data communications in the legacy wireless network specification. In this regard, legacy devices can still be supported by devices implementing new control data resources, and the new control data resources can avoid substantial interference that is typically exhibited over legacy control and/or reference signal resources by instead using the general data resources. In addition, new system devices can avoid scheduling data communication resources over the new control resources to create a substantially non-interfered global control segment. Control data can be transmitted over the segment using beacon-based technologies, reuse schemes, and/or the like.

摘要： A UE may store received samples of a wireless signal at cx1 to reduce memory usage, but then may correlate those samples with cx2 timing hypotheses to improve performance. The received sequence is resampled at cx2 instead of cx1. The UE still performs the correlation of the cx2 timing hypotheses for the performance gain, but the reference waveform is resampled with cx2 time offset. A Fast Fourier Transform (FFT) may be taken of the received and reference waveforms. In the frequency domain, resampling may be performed by multiplying the FFT of the reference waveform by a phase ramp—a pointwise multiplication in the frequency domain with a constant magnitude sequence whose phase varies linearly.

摘要： Techniques for performing power control of multiple channels sent using multiple radio technologies are described. The transmit power of a reference channel, sent using a first radio technology (e.g., CDMA), is adjusted to achieve a target level of performance (e.g., a target erasure rate) for the reference channel. The transmit power of a data channel, sent using a second radio technology (e.g., OFDMA), is adjusted based on the transmit power of the reference channel. In one power control scheme, a reference power spectral density (PSD) level is determined based on the transmit power of the reference channel. A transmit PSD delta for the data channel is adjusted based on interference estimates. A transmit PSD of the data channel is determined based on the reference PSD level and the transmit PSD delta. The transmit power of the data channel is then set to achieve the transmit PSD for the data channel.

摘要： Techniques for performing association with leakage-based metrics in a wireless network are described. Association may be performed to select a serving node (e.g., a base station or a relay) for a station (e.g., a UE or a relay). In one design, at least one metric may be determined for at least one candidate node for possible association by the station. A metric for each candidate node may be determined based on leakage of the candidate node. The leakage of the candidate node may include interference due to the candidate node at stations not served by the candidate node (excluding the station). The metric for each candidate node may include a signal-to-leakage ratio (SLR), a geometry-to-leakage ratio (GLR), or a throughput-to-leakage ratio (TLR). A serving node for the station may be selected from among the at least one candidate node based on the at least one metric.
