    Abstract: Embodiments are described that may help to provide wireless service in a circuit-switched fall back scenario. In particular, when a user entity (UE) falls back from a first network to a second network to conduct a voice call, the first network may instruct the UE to scan a certain predetermined channel or channels for coverage from the second network. However, certain types of base stations typically operate on unlisted channels that differ from the predetermined channels that the UE is instructed to scan. Accordingly, a UE may pre-emptively scan unlisted channels, and report any unlisted channel that is detected to the first network. The first network can then coordinate with the second network to re-provision the base station that was operating on an unlisted channel, to instead operate on one of the predetermined channels that a UE will be instructed to scan during fall back to the second network.

    Abstract: Coordinated multipoint (CoMP) may involve coordination between multiple sectors to receive and/or process a given user equipment's uplink signal. Embodiments herein may help to intelligently select the particular sectors that should coordinate to provide uplink CoMP, based on the types of applications being served in sectors that are candidates to provide uplink CoMP. For example, a base station serving a primary sector in an CoMP group that includes two or more candidates from which to select a secondary sector sectors for uplink CoMP, may evaluate the application being served by traffic flows in these candidates, in an effort to select secondary sectors having lower-priority traffic flows.

    Abstract: Methods and systems are disclosed that support the aggregation of acknowledgement messages and control messages. Advantageously, acknowledgement and negative acknowledgement indications for multiple client nodes are combined into a single aggregated message which is broadcast or multicast to the multiple client nodes. Based on unique identifiers assigned to each client node, client nodes are grouped such that the aggregated acknowledgement messages can be efficiently encoded to conserve both network capacity when they are transmitted, as well as processing capacity when they are parsed by the client nodes. If code division multiple access (CDMA) technology is used, the aggregated acknowledgment message can be transmitted without CDMA spreading to effectively broadcast or multicast it to multiple client nodes. A similar technique can be employed for the efficient broadcast or multicast of aggregated control messages.

    Abstract: Data identifying a plurality of wireless coverage areas in a region may be obtained. The data may identify geographic locations of the wireless coverage areas. Possibly based on the data, the wireless coverage areas may be arranged into a plurality of mutually exclusive tracking area groups. Each of the tracking area groups may include multiple wireless coverage areas and may be identified by respective unique tracking area identifiers. The tracking area groups may form a geographically-defined sequence across the region. A numerical sequence of wireless coverage area identifiers may be assigned to the wireless coverage areas in the region, one wireless coverage area identifier per wireless coverage area. The wireless coverage areas of the tracking area groups may be provisioned to use the assigned wireless coverage area identifiers.

    Abstract: A mobile station receives forward link signals and transmits reverse link signals for a communication session conducted via a wireless network. A controller maintains a reverse-active set that defines which sectors of the wireless network are used to receive the reverse link signals. When the mobile station transmits a request signal requesting the communication session, the controller may create the reverse-active set to include the sector that received the request signal with the highest signal strength. During the communication session, the signal strengths of the reverse link signals may be monitored in each of a plurality of sectors to obtain reverse-link signal strengths. The controller may maintain the reverse-active set based on the reverse-link signal strengths, adding sectors that report reverse-link signal strengths greater than an add threshold and dropping sectors that report reverse-link signal strengths less than a drop threshold.
