Abstract: Systems and techniques are disclosed relating to wireless communications, and more specifically, to various systems and techniques for early termination of low rate traffic in a wireless network. A physical layer packet (PLP) grouping factor K configures the PLP into K groups and an ACK/NAK is received on each group.

Abstract: A method for performing carrier frequency offset estimation and frame synchronization is disclosed herein. In one approach, the method includes performing a first level frequency discrimination on at least one estimated channel tap to generate a frequency discriminated value; estimating a phase error from the frequency discriminated value; and, determining a predetermined frame synchronization pattern from the estimated phase error. A computer program product having code and a wireless communications apparatus for performing the method are also described herein.

Abstract: A method of reducing power consumption by waking a wireless device based on hashing a unique identifier of the wireless device is disclosed. A hash function is applied to a unique identifier; a wakeup time is determined based on the hashed unique identifier; and the wireless device is awoken at the wakeup time.

Abstract: A method for performing symbol timing estimation is disclosed herein. In one approach, the method includes defining a search space in a plurality of estimated magnitudes of channel taps; defining a search window (SW-33) in the search space; and locating a symbol timing estimate index in the search space corresponding to a maximum value of an energy of the plurality of estimated magnitudes of channel taps within the search window (1660). A computer program product having code and a wireless communications apparatus for performing the method are also described herein.

Abstract: An adaptive linearity communication device and its operation are disclosed. The adaptive linearity communication device may include a component having a linearity dependent upon a bias and a processor configured to change the bias in response to the detection of a connection between the wireless communication device and a high-capacity power source. A method of operating an adaptive linearity communication device having a bias dependent component where the device is configured to operate in a high efficiency mode in the absence of a connection between the device and a high-capacity power source, may include determining whether a high-capacity power source is connected to the wireless communication device, and varying the operation of the bias dependent component based on whether a high-capacity power source is connected to the wireless communication device.

Abstract: Systems and techniques are disclosed relating to wireless communications. Th e systems and techniques involve wireless communications wherein a process, module or communications terminal schedules communications over a frame havi ng a plurality of time slots. The process, module or communications terminal ma y be used to assign information to be transmitted between two terminals to a block of the time slots within a frame, and reordering the time slot assignments within the frame using a permutation function, the permutation function being a function of frame count.
