Abstract: A network learns capability information indicating whether a user equipment (UE) is capable of simultaneous and independent operation in multiple component carriers (CCs). The network configures a monitoring pattern for each of multiple CCs that are configured for the UE in dependence on the received capability information.

This knowledge is particularly useful if the CCs are frequency non-contiguous with one another. If the UE is not so capable, the network must assign monitoring patterns to that UE for all its configured CCs that are not independent of one another.

Abstract: A method capable of reducing a required capacity of a retry buffer of a link device when the link device transfers real-time data to a link partner through the PCIe interface determines how to resend a packet required by the link partner according to the type of the packet. When the packet is a data packet, the method determines if a pending data packet exists in a pending transmission data buffer.

When the pending data packet does not exist in the pending transmission data buffer, the link device transmits a dummy packet to the link partner. In this way, the retry buffer only requires enough capacity to store the dummy packet and buffer the command data packets.
