Abstract: A user equipment (UE) transmits uplink control information (UCI) and a base station receives UCI when the UE is configured to have a number of cells configured for operation with carrier aggregation (CA). The base station configures the UE with a code rate and the UE determines a maximum UCI payload to transmit in a subframe that results in a transmission code rate that is no larger than the configured code rate. For transmission of aperiodic channel state information (A-CSI), a number of triggering states depends on the number of cells.

Abstract: To facilitate redundancy in a distributed control system architecture used in an industrial automation environment, a user workstation is connected to multiple enterprise access switches. Separate physical connections established between an application server and the enterprise access switches are configured into a single virtual interface for the application server to provide physical media redundancy between the application server and the enterprise access switches. Redundancy switches are connected to the enterprise access switches and to a first LAN and a second LAN, and are assigned unique IP addresses but communicate using a same default gateway IP address to serve as redundant default gateways. The redundancy switches are configured with a redundancy protocol that enables transmission of duplicate data packets over the first LAN and the second LAN.

Abstract: A shared bus time interleaves 1 PPS signal and control and coordination information between a primary timing source and line cards that need to be synchronized using the 1 PPS signals. The shared bus utilizes 1 second frames divided into time slots. The 1 PPS signals are interleaved at predetermined locations in the frame so the delays introduced by interleaving the 1 PPS data in time can be precisely removed. While the bus is not being used for 1 PPS signals, the bus is available to send control and coordination information between the line cards and the primary timing source, avoiding the use of another system and increasing utilization of an available communication path.
