Abstract: Systems and methods are disclosed to provide offloading procedures that reduce signaling load. Specifically, embodiments of the present disclosure provide offloading techniques that enable signaling overhead caused by attachment procedures to be avoided when user equipment (UE) reconnects to a cellular network after offloading data to a Wireless Local Area Network (WLAN). According to an embodiment, at least one Public Data Network (PDN) is kept connected through the cellular network access when other PDN connections are offloaded to WLAN. According to another embodiment, a PDN connection through cellular network access is suspended, rather than detached, when data is offloaded to WLAN.

Abstract: Methods and configurations for mitigating intermodulation between a first transceiver and a co-located second transceiver are provided. A method includes determining when the transceivers are concurrently transmitting, and when they are concurrently transmitting, changing a transmission channel of the second transceiver to mitigate the intermodulation when it is determined that the intermodulation is affecting at least one of the first and second transceivers. The first method also includes sending a look-ahead signal from the first transceiver to the second transceiver indicating when the first transceiver will be transmitting, and completing all transmission activity of the second transceiver prior to a transmission by the first transceiver. A second method also includes implementing a schedule for the first transceiver, which designates regular transmission and reception opportunities, communicating the schedule to the second transceiver, and only allowing the second transceiver to transmit when a transmitter of the first transceiver is inactive.

Abstract: Embodiments provide WiFi and LTE tailored transceiver radio frequency (RF) filtering techniques and configurations to enable coexistence between WiFi and LTE transceivers operating in close proximity. In particular, embodiments provide filtering techniques to reject emissions from LTE into WiFi, and vice versa. The filtering techniques eliminate the need for additional isolation between LTE and WiFi antennas (approximately 50 dB), which is beyond what is achievable in practice. Embodiments can be tailored according to different use cases of the WiFi and LTE transceivers (e.g., fixed CPE, portable router, smart phone with tethering).

Abstract: Apparatuses and methods are provided for determining operating modes of a communications link for a user equipment (UE) in a communications system based on whether the UE is configured for network coded transmission control protocol (TCP-NC). The operating modes can include physical layer channel error recovery, modulation, channel selection, among others. For example, physical layer channel error recovery can be scaled-back, or disabled, when TCP-NC is available because it is a redundant error recovery scheme. Accordingly, power can be saved, higher spectral efficiency can be achieved, and the user experience can be improved while the TCP-NC protocol recovers any data loss due to channel, errors.
