Abstract: Mechanisms are provided for a user equipment (UE) to determine to use a shared resource such as an antenna to access a land based wireless communication system or a satellite communication system. The UE can provide a first priority indication to indicate whether to access the land based wireless communication system based on one or more wireless link metrics of the land based wireless communication system or one or more application metrics for applications using the land based wireless communication system; and provide a second priority indication to indicate whether to access the satellite wireless communication system based on one or more service metrics provided by the satellite wireless communication system. The UE can determine to use the shared resources to access the land based wireless communication system or the satellite communication system based on the first priority indication and the second priority indication.

Abstract: Embodiments described herein relate to an apparatus, system, and method for controlling access to multiple antennas in a mobile device. The mobile device may determine priority among a first protocol stack associated with a first subscriber identity module (SIM) in the mobile device and a second protocol stack associated with a second SIM in the mobile device. The mobile device may lock control of a position of a switch to the first protocol stack based on determining the priority among the first protocol stack and the second protocol stack. The switch may control access to the multiple antennas. Accordingly, the second protocol stack may be unable to modify the position of the switch when control of the switch is locked to the first protocol stack.

Abstract: A method and system of estimating frequency offset at a subscriber station is disclosed. One method includes the subscriber station receiving a composite signal, wherein the composite signal includes multi-carrier signals transmitted from a plurality of base stations. The subscriber station selects a first pair of multi-carrier symbols of the composite signal, wherein each multi-carrier symbol of the first pair of multi-carrier symbols includes a pilot sub-carrier having a common sub-carrier index. The subscriber station selects a second pair of multi-carrier symbols of the composite signal, the second pair having different symbol indices than the first pair, but having a same symbol index separation, wherein each of the multi-carrier symbols of the second pair of multi-carrier symbols includes a pilot sub-carrier having a second common sub-carrier index.

Abstract: Techniques are disclosed for obtaining and maintaining synchronization of the TTR clock during a Channel Discovery Phase of DSL transceiver initialization for a DSL service operating in a TCM-ISDN crosstalk environment. The customer premises DSL transceiver achieves synchronization of its TTR clock throughout the Channel Discovery Phase of the DSL initialization procedure using a TTR indication signal transmitted by the central office transceiver. In addition to enabling basic communications, keeping TTR synchronization improves the accuracy of quiet noise measurement and the reliability of message exchanges, even on very long and noisy loops.
