Abstract: For channel estimation in a spectrally shaped wireless communication system, an initial frequency response estimate is obtained for a first set of P uniformly spaced subbands (1) based on pilot symbols received on a second set of subbands used for pilot transmission and (2) using extrapolation and/or interpolation, where P is a power of two. A channel impulse response estimate is obtained by performing a P-point IFFT on the initial frequency response estimate. A final frequency response estimate for N total subbands is derived by (1) setting low quality taps for the channel impulse response estimate to zero, (2) zero-padding the channel impulse response estimate to length N, and (3) performing an N-point FFT on the zero-padded channel impulse response estimate. The channel frequency/impulse response estimate may be filtered to obtain a higher quality channel estimate.

Abstract: Various aspects of the disclosed approach described herein allows a reduction of preamble overhead by tailoring transmitted packet preambles based on an expected level of clock-related offset between a transmitter and a receiver for a pair of communicating nodes. An estimate may be maintained at the transmitter of maximum time and frequency offsets between the transmitter and the receiver. The estimate may then be utilized to create a customized preamble sequence for generating the packet preamble. The estimate may also be utilized to select a particular modulation technique for the packet preamble.

Abstract: Embodiments describe a varied transmission time interval in wireless communication system. According to some embodiments is a method for assigning a transmission time interval. The method can include measuring a channel condition and/or a data rate of packet communicated by at least one wireless device. Based in part on the data rate and/or channel condition information, a determination can be made whether to schedule a long transmission time interval or a short transmission time interval to the packet. A long transmission time interval can be scheduled if the channel condition is poor and/or there is a low data rate. A short transmission time interval can be scheduled if the channel condition is good and/or the data rate is high or fast. The method can be repeated for multiple wireless devices. Also included is an alternative interlacing structure that supports both long transmission time intervals and short transmission time intervals.

For example, an erasure signature packet comprising a first data pattern is transmitted on the assigned resource when there is no actual data to transmit on the assigned resource.

Abstract: Systems and methodologies are described that facilitate resolving resource assignment conflicts between access terminals in a wireless communication environment. A first access terminal may receive a persistent, or “sticky” assignment of a set of resources, such as subcarriers. In the event that a second access terminal requires a brief resource assignment, a time-limited, or “non-sticky” resource assignment may be granted to the second access terminal. If a resource in the non-sticky assignment is already assigned to the first access terminal via the sticky assignment, the first access terminal may receive an indication of the conflict along with information related to a duration of the non-sticky assignment, may surrender the conflicted resource, and may resume control over the conflicted resource after the termination of the non-sticky assignment.

Alternatively, an access terminal determines what information needs to be sent to the access point.

If sufficient resources are not available at the given time, the transmission of an indication of acknowledgment is delayed until sufficient resources are available.

Upon determination of channel degradation, the access point can decide whether to ignore messages sent from the access terminal to instruct the access terminal to cease transmission.

Abstract: Systems and methods are described that mitigating coverage gaps near region boundaries using a plurality of multi-sector broadcast (MSBC) paging channels in wireless networking environments. One or more MSBC paging channels can be assigned unique time slots, such that although the channels can be identical, they are disjointed in time. Accordingly, such channels and/or dynamically generated paging zones associated therewith can be overlapped in areas where wireless device density is high and requires substantial paging capacity. Additionally, a single paging channel can be employed in multiple instances in a paging region without overlap to mitigate inter-channel interference.

Abstract: Systems and methods for controlling a delay associated with paging a remote device. In one implementation, a paging device arranges page operations such that if one of two consecutive page scans performed by a remote device occurs during a response scan, the other page scan occurs during the transmission of a page. In another implementation, a device scanning for a page arranges page scans such that if one of two consecutive page scans occurs during a page response scan, the other page scan occurs during the transmission of a page. In another implementation, a device scanning for a page performs a series of sets of separate page scans, wherein the time interval between two of separate scans in a set is less than the time interval between adjacent sets. The page scans in a set are configured to ensure that one of them occurs during the transmission of a page.
