Abstract: A device obtains proof of its authority to use a first set of selectively activated features (first proof). An authorization server signs the first proof with its private key. The device sends a request to use a network service to a network node. The device sends the first proof to the network node. The network node validates the first proof using a public key of the authorization server. The network node grants the request to use the network service. The device sends a request for proof of authority for the network node to provide the network service (second proof). The device obtains the second proof, signed by another authorization server, and validates the second proof before using the network service. The first proof and the second proof each include a list of selectively activated features, where the selectively activated features are needed to use or provide the network service.

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: Disclosed herein are techniques for light beam scanning in a light detection and ranging (LIDAR) system. The LIDAR system includes a beam shaping subsystem configured to generate an illumination pattern elongated in a first direction, and a scanning subsystem configured to direct the elongated illumination pattern towards a plurality of positions along a second direction different from the first direction. The LIDAR system further includes a sensor configured to generate a detection signal in response to detecting light reflected by a target object illuminated by the elongated illumination pattern, and a processor configured to determine a characteristic of the target object based on the detection signal.

Abstract: A method and apparatus for admission control in a communication system. An Access Network (AN) element determines available resources. When available resources are sufficient to support the requirements of a requested application flow, the AN admits the application flow. The AN periodically, and on trigger events, updates a measure of available resources. The admission control may operate in coordination with a scheduler applying a compensation factor to each flow type, and a compensation factor for aggregate flows of a given user.

Abstract: A method and apparatus for allocating and using a resource to transmit wireless information signals to a plurality of subscriber units wherein application flows are selected based on associated Quality of Service (QoS) requirements. Compensation factors are evaluated for a plurality of QoS requirements. For a violation of a given QoS requirement, the corresponding compensation factor is calculated and applied to an adaptive weight, else the compensation factor is set to a default value.

Abstract: Embodiments disclosed herein relate to methods and systems for providing adaptive server selection in wireless communications. An access terminal may be configured to determine a forward link quality metric associated with each of a plurality of sectors serviced by a plurality of access points; assign credits to each sector in relation to the forward link quality metric; and change a data source control (DSC) value if the credits accumulated for a non-serving sector at a DSC change boundary is greater than a predetermined threshold, where the non-serving sector and the serving sector for the access terminal belong to different cells. The access terminal may be further configured to change a data rate control (DRC) cover in accordance with the DSC change. The use of DSC may provide an early indication of handoff, thereby allowing the service outage associated with server switching to be substantially reduced.

Abstract: Techniques to reduce transmit power required for transmission of messages from an access terminal to reduce interference to transmissions from other access terminals. In one aspect, messages to be transmitted are defined and/or coded such that they may be detected at different received signal qualities. The codewords may be defined having different distances to their nearest codewords. In another aspect, messages to be transmitted are assigned to different points in a signal constellation, with the points being located such that they may be received at different signal qualities. Codewords that may be received at a lower signal quality may be assigned to messages more likely to be transmitted at higher transmit power levels (e.g., when the access terminal is located further away) or to more frequently transmitted messages.

Abstract: A network entity includes a processor configured to regulate the data rate of transmissions over a wireless channel from a base station to a subscriber station based on feedback from the subscriber station, the feedback relating to the wireless channel conditions, the processor being further configured to determine a substitute data rate for one or more transmissions over the wireless channel.

Abstract: A communication network having a plurality of subscriber units receive a finite resource from a common node is disclosed. Individual subscriber units may seize the finite resource of the common node to the exclusion of all other subscriber units in the network. A scheduler allocates the finite resource to the individual subscriber units based upon a weight associated with the individual subscriber units. The scheduler determines the weight for each of the subscriber units based upon an instantaneous rate of consuming the finite resource.

Abstract: This disclosure provides a synchronous packet manager containing a data structure for scheduling future synchronous packet transmissions and arbitrating between synchronous and asynchronous packet transmissions. Slots required for transmitting a synchronous packet are reserved by marking the corresponding entries in a synchronous packet reservation table. Rather than writing packets to many different queues, the application software fills in a single reservation table per BTS sector.

Abstract: An apparatus for a wireless communication system that includes means for determining available resources in the wireless communication system and means for determining an admission of a flow.
