Abstract: The disclosure provides for managing voice calls in Circuit Switched Fall Back (CSFB) communication devices that are configured to make voice calls using both Circuit Switched (CS) networks and Internet Protocol (IP) over Packet Switched (PS) networks. The device may determine, when registered with a PS network, a signal strength of a CS network at the device. The device may select, based on the signal strength of the CS network, one of the CS network and the PS network for the voice call. The device may establish the voice call using the selected network. The device may receive a user request for initiating a voice call, and initiate a voice call over the selected network automatically using an application corresponding to the selected network. The device may also register with a voice over IP (VoIP) service over the PS network based on the signal strength of the CS network.

Abstract: The present disclosure presents a method and an apparatus for heavy active estimation mechanism for backhaul management at a small cell base station. For example, the method may include identifying, at the small cell base station, that a throughput of a user equipment (UE) in communication with the small cell base station is potentially limited due to backhaul congestion at the small cell base station, establishing a proxy flow between the small cell base station and a transmission control protocol (TCP) proxy peer in response to the identifying, wherein the proxy flow data packets are transmitted from the small cell base station to the TCP proxy peer or from the TCP proxy peer to the small cell base station, calculating a throughput of the proxy flow for a pre-determined time period, and determining whether the throughput of the UE is limited by backhaul congestion at the small cell base station based on the calculated throughput of the proxy flow. As such, heavy active estimation mechanism for backhaul management at a small cell base station may be achieved.

Abstract: Fractional frequency reuse (FFR) is defined based on a mobility condition of an access terminal. For example, upon determining that an access terminal is moving (or at a cell edge, or experiencing poor link conditions, etc., due to mobility), FFR may be defined for the serving access point of the access terminal and/or for neighbor access points to maintain acceptable link quality for the access terminal. In particular, FFR may be defined in a manner that frees-up or otherwise reserves resources for the access terminal. For example, the serving access point may allocate additional sub-bands for the access terminal and/or increase the power levels used on the sub-bands allocated for the access terminal. In addition, neighbor access points may back-off these sub-bands.

Abstract: Wireless communications systems and methods related to UE cooperation are provided. A base station (BS) may assist a UE in cooperating with other UEs. A UE may transmit a cooperative UE update request to aBS, indicating a number of candidate cooperative UE sets. The UE may also transmit information to the BS about the candidate cooperative UE sets such as UE capability information, location information, and channel measurements. Additional measurements maybe requested by the BS. The BS may use the information from the UEs together with BS-side information such as configuration information and TRP information in order to determine which of the candidate cooperative UE sets is preferred. The BS may then configure and communicate with selected cooperative UE set.
