Abstract: Methods and systems are disclosed for communicating in a wireless communications system utilizing a plurality of frequency bands for downlink (DL) transmission and a plurality of frequency bands for uplink (UL) transmission. In an embodiment, a mobile device receives a DL signal via a DL frequency band. The DL signal contains DL-UL frequency band association information which is used to determine a UL frequency band for UL transmission. The mobile device configures its radio-frequency (RF) circuitry to operate in the UL frequency band for UL transmission.

Abstract: An operation method of a terminal in a communication system may comprise: performing a monitoring operation to receive BWP configuration information for common downlink communication; in response to receiving the BWP configuration information from the base station, configuring a common frequency region for the common downlink communication based on the BWP configuration information; receiving DCI including scheduling information of the common downlink communication from the base station; and performing the common downlink communication with the base station in the common frequency region by using a frequency resource indicated by the scheduling information, wherein the common downlink communication is communication between the base station and a plurality of terminals including the terminal.

Abstract: Traffic services for network addresses may be provided within threads executing within a main process for managing the traffic services. The threads may share resources within the main process, reducing the computing resources consumed to provide traffic services to large pools of network addresses. According to one embodiment, a method may include executing a main process for managing traffic services; determining, by the main process, a configuration specifying at least one or more destination addresses; instantiating, by the main process, one or more traffic service (TS) threads for the one or more destination addresses; and/or processing, by the one or more traffic service (TS) threads, inbound traffic for the corresponding one or more destination addresses. Other aspects and embodiments for traffic management are also disclosed.
