    摘要： Systems and methods for providing an efficient network entry for a mobile station in RF communications systems with fully configured and partially configured carriers are described. A distinguishing parameter for fully configured carriers is determined. A mobile station receives a carrier and determines whether a fully configured carrier has been received. The mobile station performs synchronization with a base station using the detected fully configured carrier and completes a network entry procedure. In one method embodiment, the distinguishing parameter is a unique preamble characteristic. In another method embodiment, the fully configured carrier frequency is part of messages broadcast by both the fully configured and partially configured carriers. In yet another method embodiment, the carrier raster for fully configured carriers is distinguishable from the carrier raster for partially configured carriers. Latency is reduced for the network entry process for the mobile stations.

    摘要： Various embodiments are disclosed relating to the optimization of handovers and ranging in a wireless network. According to an example embodiment, an information request may be received, which may include a handover information request, such as a ranging request for handover. Resources for handover information requests may be allocated or applied at a higher priority level than at least some non-handover information requests. Further, a mobile station may perform ranging with a base station, wherein a first value of a retransmission timer at the mobile station is used for non-handover ranging, and a second value of the retransmission timer that is less than the first value is used for handover ranging. Further, a ranging request message including a ranging purpose indication indicating a ranging purpose may be received. Resources for processing the ranging request message may be allocated at a priority level based on the ranging purpose indication.

    摘要： A system for managing wireless communication in view of other potentially interfering wireless signal sources. Signal-related information may be collected from one or more apparatuses that are participating in a network. The information may then be evaluated in order to determine expected signal activity in the environment in which the apparatuses are operating. In some instances the signal activity may then be compared to a scan schedule utilized, for example, to identify legacy apparatuses operating in the environment. This scan schedule may be altered to avoid potential conflicts that may exist with the expected signal activity. The scan schedule may then be communicated to the networked apparatuses.
