A method of reducing interference comprises estimating an interference level in a mobile network. In the event that the interference level is detected as being above a satisfactory threshold, the method comprises selecting an infrastructure unit of one or more infrastructure units which is currently operating as one of a base station or an uplink and downlink relay node configured to relay uplink and downlink transmissions, and configuring the infrastructure unit to operate as an uplink relay node such that it does not send downlink signals. In the event that the interference level is detected as being below a satisfactory threshold, the method comprises selecting an infrastructure unit currently operating as an uplink relay node such that it does not send downlink signals, and configuring the infrastructure unit to operate as one of a base station or an uplink and downlink relay node configured to relay uplink and downlink transmissions.

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for configuring a Secondary Cell (SCell) with Physical Uplink Control Channel (PUCCH) resource; receiving an Radio Resource Control (RRC) signaling indicating that the PUCCH resource is de-configured from the SCell, wherein the RRC signaling includes an indication which indicates whether the UE activates or deactivates the SCell from which PUCCH resource is de-configured; de-configuring the PUCCH resource from the SCell; and activating or de-activating the SCell according to the indication after the UE de-configures PUCCH from the SCell.

Millimeter-wave (mmWave) band communication is a very promising technology for 5G small cells. In practice, such a new system will coexist with legacy or evolved microwave band systems, such as E-UTRAN LTE macro-cell cellular systems, for a long time to come. Considering the typical scenarios where a macro cell offers umbrella coverage for clusters of small cells, several user plane (U-plane) architectural choices of macro-assisted 5G mmWave systems from both UE and network's perspectives are evaluated. The proposed On-demand Reconfiguration U-Plane Architecture (ORUA) for Macro-assisted Millimeter Wave (mmWave) small cells is designed to meet 5G expectations of dense deployment of small cells and UEs and beamformed intermittent Gbps links.

A wireless access network node receives, from a coordinating network node, configuration information relating to a configuration of an uplink signal comprising a given uplink sequence selected by a user equipment (UE) from a plurality of uplink sequences and to be transmitted by the UE, the configuration information to enable the wireless access network node to monitor for the uplink signal, the plurality of uplink sequences mapped to respective power levels. The wireless access network node monitors for the uplink signal according to the configuration while the wireless access network node is in an off state, and determines a power level of the uplink signal based on the given uplink sequence in the uplink signal detected by the wireless access network node.

A user equipment, a small cell and an operation method thereof are provided. The small cell includes a processor and a transceiver. The processor is configured to generate a maintaining downlink signal when the small cell is in an off-state. The maintaining downlink signal utilizes fewer radio resources compared to a normal downlink signal which is generated when the small cell is in an on-state. The transceiver is electrically connected to the processor and configured to continuously transmit the maintaining downlink signal when the small cell is in the off-state and receive an uplink signal from the user equipment. The processor further switches the small cell from the off-state to the on-state according to the uplink signal.
