Abstract: A joint channel estimation and data detection technique for decoding an uplink control channel using resource elements that are redundant in acknowledgement and negative acknowledgement uplink control channel transmissions is disclosed. To improve the performance of a decoder, channel estimation can be performed using reference signals (pilot symbols) to determine the characteristics of a channel at given locations within a subframe. For some uplink control channel formats, however, there aren't dedicated locations for reference signals/symbols, and so channel estimation is not performed.

In response to determining the set of resource blocks include both the first set of resource blocks and the second set of resource blocks, the data transmission can be transmitted in at least one of the first set of resource blocks and the second set of resource blocks.

Abstract: A method for assisting in multipoint data flow control in a wireless communication system having a number, n+1, where n?1, of wireless-transmission points. The method comprises obtaining, for each of the wireless-transmission points, a round trip time of a present sampling period for data travelling to a user equipment via a respective wireless-transmission point and an acknowledge message travelling back. A round trip time skew is computed for the present sampling period for individual wireless-transmission points. The round trip time skew is a difference between the obtained round trip time of a respective wireless-transmission point and a reference value. A reference round trip time value is provided for each wireless-transmission point in dependence of the round trip time skews. A rate control signal is generated, for each of the wireless-transmission points, in dependence of a respective reference round trip time value. Corresponding arrangements are also disclosed.

Abstract: A network element includes output ports, a crossbar fabric and a scheduler. The output ports are organized in groups of multiple output ports selectable over predefined time slots in accordance with a cyclic mapping assigned to each group. In each time slot, the crossbar fabric routes to fabric outputs data received from the buffers via fabric inputs, in accordance with a routing plan. The scheduler determines and applies the routing plan for transmitting packets from the buffers to the communication network via the crossbar fabric and output ports. When in a given time slot, a required readout rate from a given buffer exceeds a maximum rate, the scheduler selects a group of the output ports to which the given buffer is routed in that time slot, and modifies the cyclic mapping for that group to reduce the required readout rate from the given buffer in the given time slot.

A method, apparatus, and computer-readable medium are disclosed extend a TB over more than one slot to maximize utilization of a TO duration, for improved resource utilization and service quality. A method, apparatus, and computer-readable medium implemented by a communication device are disclosed to receive a signaling message, to configure a flexible transport block (TB) to extend the TB over more than one slot. Then the communication device may receive a portion of the flexible TB, based on the received signaling message.

Abstract: Low-cost network switches and other computing systems are described herein. A low-cost network switch can operate at a lower ambient temperature (e.g., 55° C.) than conventional switches, thereby enabling the use of lower cost components (e.g., optical components that are not rated for operation at up to 70° C.). The network switch can utilize a power bar pass-through card that provides power from an enclosure bus bar to components of the network switch in lieu of a power supply unit. Additionally, ports of the network switch can operate in a 2×50G mode in which a network switch port capable of communicating at 100 Gbps interfaces with two external ports each capable of communicating at 50 Gbps. Communication in 2×50G mode can be supported by a four-channel Y-cable, in which the four channels are utilized by the network switch port and fan-out to two channels to each of the two external ports.
