Abstract: An apparatus for wireless communication obtains a first metric of a cell based on signals received by a WWAN radio tuned to a common frequency, and a second metric of the cell based on signals received by a WLAN radio tuned to the common frequency. The apparatus determines a calibration factor based on the first and second metrics, and performs cell search and cell measurement based on the calibration factor and signals received by the WLAN radio tuned to a target frequency. The common frequency may be a serving frequency of the WWAN, in which case the first and second metrics are one of frequency or power metrics and the calibration factor is one of a frequency offset and a power offset. The common frequency may also be a target frequency for inter-frequency measurements of the WWAN, in which case the calibration factor is based primarily on power measurements.

Abstract: Wireless communication systems and methods of scheduling access terminal responses to an interactive multicast message are provided. A radio access network (RAN) generates an access control message (ACM), the ACM indicating feedback instructions for a plurality of access terminals (ATs) belonging to a given multicast group. The feedback instructions of the ACM designate a temporary manner in which the plurality of access terminals are to respond to an interactive multicast message. The target ATs receive the interactive multicast message as well as the ACM. The target ATs, or multicast group members, respond to the interactive multicast message based on the feedback instructions for the plurality of access terminals indicated by the ACM.

Abstract: 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.

Abstract: An access network (AN) receives a call announcement message for transmission to an access terminal (AT). The AN initiates, in response to the received call announcement message, a physical-layer synchronization procedure for at least one channel between the AN and the AT, the physical-layer synchronization procedure associated with a transition of the access terminal to a dedicated channel state. The AN performs the initiation by sending a message to the AT. In response to the message, the AT monitors a downlink channel for receipt of the call announcement message. The AN then transmits the call announcement message on the downlink channel to the access terminal, and the AT receives the call announcement message due to the monitoring. The call announcement message is transmitted either (i) before the physical layer synchronization procedure completes or (ii) before a transmission of a reconfiguration complete message indicating completion of dedicated channel state transition.

Abstract: In an embodiment, a secondary communication terminal (CT) executes a client application to engage in a client application session (CAS), the secondary CT configured to connect to a primary CT over a local wireless connection (LWC), the primary CT having a higher-quality user interface environment as compared to the secondary CT. The secondary CT establishes the LWC with the primary CT during the CAS and, responsive to the establishment, negotiates with the primary CT to selectively transition the CAS to the primary CT. Alternatively, the primary CT executes the client application before the establishment and negotiates with the secondary CT to selectively transition the CAS to the secondary CT. In another embodiment, the primary CT hosts the CAS while the LWC is established with the secondary CT. Then, upon disconnection of the LWC, the secondary AT selectively transitions the CAS to the secondary CT.
