Abstract: Various exemplary methods and apparatus are directed to using Visible Light Communication (VLC) in a downlink, e.g., a supplemental downlink, in combination with a wireless radio downlink/ uplink pair. A gateway is coupled, via a wireline link, to a VLC access point. In some embodiments, the gateway includes a wireless radio base station. A user equipment device detects a visible light signal from the VLC access point, and transmits a radio signal to a communications device, e.g., a gateway including a base station or a macro base station, indicating that the UE device is in a VLC coverage area. The gateway configures the VLC access point to serve as a supplemental wireless cell which supports downlink communications. The gateway sends traffic signals to the VLC access point, via the wireline, which are converted by the VLC access point into VLC signals which are transmitted. The UE device receives VLC downlink traffic signals and transmits a corresponding acknowledgment signal via an uplink radio channel.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with improving QoE in RAN congestion. In one example, a communications device is equipped to indicate a quality control indicator (QCI) for each of a plurality of applications that communicate with a RAN over a bearer, receive information regarding modification of the bearer or additional bearers based on the QCIs, and modify the bearer or additional bearers according to the information to achieve a desired QoE for at least one of the plurality of applications. In another example, a RAN is equipped to receive a QCI for each of a plurality of applications related to a bearer from a UE, and modify the bearer or adding additional bearers for communicating with the UE based on the QCI for each of the plurality of applications to improve QoE at the UE.

Abstract: Techniques for signaling carrier bandwidths supported by a user equipment (UE) for carrier aggregation are disclosed. A UE may be configured with a plurality of carriers for carrier aggregation. Each carrier may have one carrier bandwidth of a set of possible carrier bandwidths. The set of possible carrier bandwidths may be dependent on a band in which the carrier belongs. Multiple combinations of carrier bandwidths for the plurality of carriers may be possible. The UE may identify at least one supported carrier bandwidth combination for the plurality of carriers. Each of the supported carrier bandwidth combinations may include a particular carrier bandwidth for each configured carrier. The UE may send signaling indicative of the at least one supported carrier bandwidth combination. The UE may thereafter communicate on the plurality of carriers based on a carrier bandwidth combination selected from the supported carrier bandwidth combination(s).
