Abstract: This disclosure provides methods, devices and systems for reducing power consumption in neighbor awareness networking (NAN) devices. Some implementations more specifically relate to dynamically adjusting a NAN device link (NDL) schedule to reduce the idle duration of a NAN data interface (NDI). The NDL schedule identifies a number of NAN slots, per discovery window (DW) interval, during which an NDL is available for data communications between NAN devices. In some aspects, a NAN device may measure congestion on the wireless channel during each NAN slot within a DW interval and may dynamically update the NDL schedule based on the measured congestion. In some other aspects, a NAN device may measure throughput on the NDL during each NAN slot within a DW interval and may dynamically update the NDL schedule based on the measured throughput.

Abstract: In some aspects, a method for adjusting an operating frequency of a memory controller is provided, wherein a graphics processing unit (GPU) accesses a memory via the memory controller. The method includes monitoring activity of the GPU to determine an active time of the GPU, comparing the determined active time with an active threshold, and, if the determined active time is greater than the active threshold, increasing the operating frequency of the memory controller.

Abstract: An antenna for use with a receiver in a wireless communications system includes antenna elements for generating antenna patterns, and a first module for applying weights to a signal received at each of the antenna elements to generate a selected one of the antenna patterns. A second module detects the received signal at each of the antenna elements. A combiner combines the received signal detected at each of the antenna elements to produce a combined received signal for a selected antenna pattern. A third module determines a signal quality metric for the combined received signal at each selected antenna pattern. The first module is responsive to the determined signal quality metrics for adjusting the weights to generate a preferred antenna pattern.

Abstract: An antenna apparatus that can increase capacity in a cellular communication system. The antenna operates in conjunction with a mobile subscriber unit and provides a plurality of antenna elements, each coupled to a respective signal control component such as a phase shifter. The phase shift for each antenna element is programmed for optimum reception during, for example, an idle mode when a pilot signal is received. The antenna array creates a beam former for signals to be transmitted from the mobile subscriber unit, and a directional receiving array to more optimally detect and receive signals transmitted from the base station. By directionally receiving and transmitting signals, multipath fading is greatly reduced as well as intercell interference. The phase shifters are adjusted in a coarse and a fine mode. In the coarse mode all phase shifters are jointly incremented through several phase shift values until a signal quality metric is optimized.

Abstract: A wireless area network (99) includes at least one access point (100), provides for multiple possible network devices (104, 105), and is located in a structure (108) with wiring (201). The wireless area network includes an interface unit (200) that extends the range of the network devices (104, 105). The interface unit (200) is for receiving wireless signals from the access point (100) and for transmitting the wireless signals on the wiring (201). The interface unit (200) is also for receiving the wireless signals from the wiring (201) and for transmitting the wireless signals to the access point (100).
