Abstract: A method for wireless communications includes reducing transmission power, by a femto base station, at its radio frequency (RF) transmitter, and cancelling a transmitted data signal of the RF transmitter at its network listen (NL) receiver. The reduction occurs in response to: occurrence of a network listen process; and/or a signal quality of the local macro coverage area exceeding a threshold quality. Additionally or alternatively, the femto base station may detect quality of its macro coverage area, and respond to the signal quality being below the threshold quality by: suspending reduction of transmission power and cancellation of the transmitted data signal; suspending the RF transmitter during transmission gaps assigned to user equipments (UEs); and triggering an NL operation in response to suspension of the RF transmitter, wherein the NL operation occurs within the duration of each of the transmission gaps.

Abstract: The disclosure uses a low-cost local wireless network to expand coverage of a multicast service. A user device determines whether a signal strength for a detected wireless multicast service is greater than a threshold, determines whether a low cost local wireless network is available, and communicates with an application server over the low cost local wireless network based on the signal strength being not greater than the threshold and the low cost local wireless network being available. A server receives a request from a user device to send multicast communications to the user device over the low cost local wireless network serving the user device, wherein the user device sends the request based on a signal strength of a detected wireless multicast network being less than a threshold and the low cost local wireless network being available, and communicates with the use device over the low cost local wireless network.

Abstract: Methods, systems, and devices for facilitating mobility between flexible bandwidth systems and other bandwidth systems are provided. These tools and techniques that provide mobility between different bandwidth systems may facilitate supporting circuit-switched (CS) services, such as CS voice services. Some embodiments provide for determining flexible bandwidth capable devices, such as user equipment. Some embodiments involve core network redirection where a core network may direct the handling of circuit-switched services when a flexible bandwidth system does not support the CS services. Some examples provide for radio access network determined handling of CS services when a flexible bandwidth system may not support the CS services. Some embodiments provide for transitioning to a flexible bandwidth system. Some embodiments provide for transitioning from flexible bandwidth systems to non-flexible bandwidth systems that have no support for some or all CS services, other flexible bandwidth systems, and/or systems that natively support CS voice services.
