摘要： An embodiment is directed to an access network that configures set of paging indicator (PI) bits within a quick paging channel (QPCH) cycle to page a group of access terminals. An access terminal within the group receives the QPCH cycle, and evaluates the PI bits to determine whether a unicast page and/or group page is present. Another embodiment is directed to selecting less than all timeslots in one or more control channel cycles of a downlink control channel, and configuring a page message to convey the selected timeslots to an access terminal. The access terminal receives the configured page message and decodes information only within the selected timeslots. Another embodiment is directed to generating a transport-layer message for transmission to at least one access terminal, and configuring the transport-layer message by modifying an application-layer portion of the transport-layer message. An access terminal receives the message and extracts the application-layer portion.

摘要： Embodiments are directed to monitoring downlink communication at an access terminal within a wireless communications system. The access terminal monitors data on a first downlink broadcast channel of a first network at least with a primary antenna of the access terminal, the monitored data associated with an active communication session (e.g., a high-priority multicast communication session) of the access terminal. The access terminal may optionally periodically monitor messaging information on a downlink channel of a second network with a secondary antenna of the access terminal, the primary antenna having a higher sensitivity than the secondary antenna. The access terminal maintains an exclusive allocation of the primary antenna to the first network irrespective of a quality level of the periodically monitored messaging information on the downlink channel of the second network.

摘要： Techniques and systems are disclosed for estimating an unknown image from a plurality of cone-beam computed tomography (CBCT) image projections. The unknown image is estimated by solving for minima of an expression comprising a fidelity term that is a function of the plurality of image projections and a regularization term that is responsive to a sparsity of the CBCT image projections. The minima of the expression is iteratively estimated by calculating an image gradient of the function, determining a step size based on a based on a Barzilai-Borwein (BB) formulation and adjusting the minima estimate using the projected image gradient and a step size.

摘要： A system, method, and computer device that selectively maintain an open interface to a communication control device that is controlling wireless communication to at least one of a plurality of wireless communication devices that are in a communication group, such as a push-to-talk (PTT) group. In one embodiment, the wireless communication device registers at the communication control device, such as a base station controller, and at least one interface is established between the communication control device and another computer device on the wireless communication network, such as a broadcast A10 interface with a broadcast serving node (BSN). The communication control device will then maintain the interface while the at least one wireless communication device, or at least one member device of the communication group, is registered such that group communications can more rapidly be delivered to the wireless communication device.

摘要： A mobile device provides first information to an access point over an out-of-band wireless link. The access point uses the first information to coarsely synchronize with a macrocell base station. The access point transmits a low power pilot signal that is formed using a pseudo-random noise (PN) sequence. The mobile device uses the out-of-band wireless link to provide second information to the access point that indicates a PN phase of the pilot signal with respect to a reference time point. The access point uses the second information to finely synchronize with the macrocell base station. The mobile device communicates with a mobile operator core network through the access point using an in-band wireless link to the access point. The mobile device compensates for propagation delay when obtaining time information. The mobile device provides additional information to the access point, which the access point uses to adjust for continued clock drift.

摘要： A network communication entity (e.g., an access terminal, access network and/or application server) obtains a location associated with a given access terminal that is attempting to participate in a given communication service, obtains a priority level of the given access terminal, determines a given level of service restriction for the given access terminal's participation in the given communication service based on the obtained location and the obtained priority level and restricts the given access terminal's participation in the given communication service based on the given level of service restriction. In an example, the priority levels can be established such that low-priority access terminals obtain a first level of service restriction within a defined location region, and a second level of service restriction outside of the defined location region, whereas high-priority access terminals obtain the first level of service restriction both inside and outside of the defined location region.
