Abstract: A system and method are provided for distributing wireless network access parameters in a multi-mode communications user terminal (UT). The method includes: establishing a link between a UT and a first communications network (i.e., a cellular network); accessing a parameters server via the first network; downloading access parameters for a wireless, second communications network (i.e., a Wireless Local Area Network); and, using the downloaded access parameters to establish a wireless link between the UT and the second communications network. The downloaded access parameters may include information such as a security key, Service Set IDentifier (SSID), traffic channel allocation, and optimization parameters including transmit power, quality of service (QoS) settings, and operational mode. Alternately, the database may cross-reference UT ID to parameters such as QoS, IP address, gateway information, subnet mask, Domain Name Server (DNS) information, or geographical location.

Abstract: Systems and methods of generating quick paging messages having nearly unique identifiers and variable capacity are described. The system generates a quick paging message identifying an access terminal to indicate the presence of a scheduled paging message for that access terminal. The system generates a quick paging notification for each access terminal having a scheduled paging message and generates a compressed nearly unique identifier of each access terminal that is notified in the quick paging message. The compression technique can vary based on the number of bits allocated to the quick paging message as well as the number of access terminals notified in one quick paging message.

Abstract: Techniques are provided for frequency spectrum sharing that allows secondary operators to access a frequency band of a primary operator without interfering with the primary operator's use of the band, while ensuring service continuity for devices of the secondary operators. For example, there is provided a method that may involve identifying an outage on a first channel of a plurality of channels of a spectrum, wherein each of the plurality of channels is allocated to one of a plurality of operators. The method may involve migrating all mobile stations in communication over the first channel of the plurality of channels to at least one other channel of the plurality of channels during the outage.

Abstract: A resource assignment method during a tune-away procedure comprises determining a first instance in time that a tune-away will initiate with respect to an access terminal, determining a second instance in time that corresponds to a latest frame boundary associated with the access terminal prior to the instance in time that the tune-away initiates, and determining resource assignment parameters associated with the access terminal and implementing the resource assignment parameters at the second instance in time. The method can further comprise ceasing communications to the access terminal over a forward link at the second instance in time and discontinuing monitoring reverse link control channels associated with the access terminal at the second instance in time.

Abstract: Access control for an access point (e.g., a cell of the access point) may be based on an access mode associated with the access point. For example, depending on the access mode, access control may involve performing a membership check for the access point. Such a membership check may be performed at a network entity, a source access point, or some other suitable location in a network. In some aspects, access control may involve performing a membership check for an access point in conjunction with a context fetch procedure. Such a procedure may be performed, for example, when an access terminal arrives at the access point after experiencing RLF at another access point.

Abstract: A quick paging channel in a random access wireless communication system includes at least one bit in a quick paging frame identifying the presence of a paging message for an access terminal or group of access terminals. The quick paging bits identifying the presence of a paging message for a first access terminal is encoded with one or more quick paging bits corresponding to one or more additional access terminals to produce one or more forward error correction bits. The jointly encoded quick paging bits are broadcast to the access terminals by time division multiplexing the quick paging frame with additional frames of information.

Abstract: Systems and methodologies are described that provide techniques for managing persistent resource assignments in a wireless communication system. An access point can generate a bitmap by mapping access terminals having persistent assignments for traffic channels to a series of bitmap bits that provide keep-alive indications for the access terminals. The bitmap can then be provided as a common keep-alive message in a broadcast or multicast transmission to the access terminals. The keep-alive message can further include CRC bits for error prevention. An access terminal, upon receiving the keep-alive message, can then determine whether a bitmap bit in the keep-alive message corresponding to the access terminal conveys a keep-alive indication for the terminal and utilize its persistently assigned traffic channels accordingly.

Abstract: Aspects are disclosed for facilitating a timing alignment in a multicarrier system. In one aspect, at least one downlink timing associated with at least one downlink carrier is determined, and an uplink timing associated with an uplink group of carriers is ascertained based on at least one downlink timing and a timing offset associated with the uplink group of carriers. Each of the uplink group of carriers is then transmitted within a threshold value of the uplink timing. In another aspect, a downlink communication is transmitted to a wireless terminal via at least one downlink carrier. This embodiment further includes assigning a timing offset to an uplink group of carriers, and providing the timing offset to the wireless terminal via the at least one downlink carrier. An uplink communication is then received via the uplink group of carriers according to the timing offset.
