The transmitter can transmit on a certain frequency or channel corresponding to that antenna, so that the various transmitters in the DAS each transmit on different frequencies. These frequencies can be detected by a receiver and can be processed to determine whether a signal at any frequency or channel expected to be received is missing. If any expected signal is missing for any frequency or channel, the receiver can infer that the antenna or a component associated with the antenna (such as cabling) may have failed. The receiver can then output an indication or notification that may be accessed by maintenance personnel and/or emergency personnel to enable them to identify and repair the non-functioning antenna or component.

    Abstract: A method and apparatus for identifying joint transmissions in unlicensed spectrum are described, including receiving, at a user equipment (UE), a frame from one or more network entities over a contention-based medium, wherein the frame includes a preamble. The method and apparatus further include determining whether the frame corresponds to a unicast transmission or a joint transmission based on the preamble. In another aspect, a method and apparatus include determining, at a network entity, whether a frame corresponds to a unicast transmission or a joint transmission. The method and apparatus include transmitting the frame with a preamble to a UE over a contention-based medium, the preamble being based on determining whether the frame corresponds to the unicast transmission or the joint transmission. For example, the type of scrambling applied to the preamble may be based on whether the frame corresponds to unicast transmission or joint transmission.

An example method for handling connections to two radio access technologies, according to some of the embodiments disclosed herein, is implemented by a mobile terminal and comprises determining (710) that a trigger condition has been satisfied, while the mobile terminal is connected to a first radio access network and in an idle state with respect to a second radio access network. Responsive to this trigger condition, the mobile terminal then automatically establishes or re-establishes (720) a connection to the second radio access network. In some embodiments, the first radio access network is a wireless local area network and the second radio access network is a cellular telecommunications network.
