Abstract: Channel state information reference signal transmission can be used to estimate channel state information. Although resources needed for channel state information reference signals can be small, when multiple bandwidths are deployed within the same orthogonal frequency division multiplexing bandwidth, estimating the channel state information can comprise a channel state information reference signal resource grid for every bandwidth. Therefore, time-frequency resources for channel state information reference signals can be high and occupy a lot of bandwidth, thereby reducing the number of resources for data transmission. Therefore, a non-orthogonal design for channel state information reference signals for a 5G air interface can mitigate bandwidth loss in a 5G network.

Abstract: Interactive content can be managed and provided to occupants of an automated vehicle to enhance their experience while in the vehicle. Orchestrator component can determine interactive content based on conditions associated with the vehicle, user preferences, video content, or other information. Interactive content can comprise video content, audio content, and control content. Video content can comprise augmented reality or virtual reality content. Control content can be used to control vehicle operation in relation to or synchronization with presentation of video content. Orchestrator component can correlate between certain roads on which the vehicle can travel and entertainment presentations presented to a vehicle occupant. Orchestrator component can control vehicle operation to have the vehicle recreate a vehicle action sequence (VAS) in a video program being presented to the occupant in the vehicle. Orchestrator component can notify nearby vehicles when VAS is be recreated, or another vehicle also can participate in VAS.

Abstract: Methods, apparatus and articles of manufacture for advertising network layer reachability information specifying a quality of service for an identified network flow are disclosed. Example methods disclosed herein to specify quality of service for network flows include receiving network layer reachability information including a first quality of service class specified for a first network flow, the network layer reachability information having been advertised by a first network element that is to receive the first network flow. Such example methods can also include updating an incoming packet determined to belong to the first network flow to indicate that the incoming packet belongs to the first quality of service class, the incoming packet being received from a second network element. Such example methods can further include, after updating the incoming packet, routing the incoming packet towards the first network element.
