    Abstract: Wireless communications systems, methods, and techniques related to signaling and determining slot and mini-slot structures are provided. A first wireless communication device transmits a first signal according to a first numerology including at least a first tone spacing. The first signal indicates a second numerology including at least a second tone spacing. The first wireless communication device transmits a second signal according to the second numerology. The first signal includes a physical broadcast channel (PBCH) signal. The second numerology is independent from the first numerology. Different slot/mini-slot structures may be utilized for varying channel types to support mixed numerology arrangements. Embodiments may utilize single and varied slot structures; single slot structures may be decoupled from transmission numerology and varied slot structures may be defined based on reference numerology. Other aspects, embodiments, and features are also claimed and described.

    Abstract: One or more selectively activated features needed at a device to use a network service may be identified. Authorization information and feature activation key(s) associated with features that the device has been authorized to activate may be obtained at the device. The feature activation key(s) may be used to activate and/or maintain activation of the authorized features that match the selectively activated feature(s) needed to use the network service. An authorization server may obtain a request to activate one or more selectively activated features of a device. The authorization server may verify that the selectively activated feature(s) are authorized to be used at the device based on an authorization agreement obtained at the authorization server. The authorization server may send proof that the device is authorized to use the selectively activated feature(s) and may send feature activation key(s) based on the authorization agreement in response to the request.

    Abstract: Techniques for selecting either a DFE or an LE for use to equalize a receive d signal, and for quickly and efficiently determining the coefficients for the selected equalizer. In an embodiment, a method is provided whereby the DFE i s initially adapted based on the received signal and a particular adaptive algorithm (e.g., the LMS algorithm) for an initial time period. A quality metric is then determined for an output of the DFE. The DFE is selected for use if the quality metric is better than a threshold value, and the LE is selected otherwise. If the LE is selected, then the initial values for the coefficients of the LE may be derived based on the coefficients of a feed- forward filter and a feedback filter for the DFE, and the LE coefficients ma y further be adapted for an additional time period prior to its use to equaliz e the received signal.

    Abstract: In a CDMA data communication system capable of variable rate data transmission, a time-division power assignment cyclically reduces the carrier power level to at least one sector to reduce interference in neighboring sectors. The base station determines a time-division power assignment for each sector and generates signals according to the power assignment. The mobile unit generates filter coefficients corresponding to each power level. The mobile unit estimates Carrier Signal-to-Interference (C/I) to determine a data rate for each power level. Previous iterations of the equalizer are stored and used to refine future estimates.
