Abstract: A method of power control can include receiving at a UE a first downlink reference signal from a repeater and a second downlink reference signal from a base station, the first downlink reference signal corresponding to a first path that is between the UE and the base station and passes the repeater, the second downlink reference signal corresponding to a second path that is between the UE and the base station. The UE estimates a first uplink path loss of the first path and a second uplink path loss of the second path and determine a first uplink transmit power corresponding to the first path and a second uplink transmit power corresponding to the second path. The UE performs an uplink transmission on the first path based on the first uplink transmit power and on the second path based on the second uplink transmit power.

Abstract: A synergetic communication method for relay node identification (ID) acquisition is proposed. The network node may generate a configuration based on the relay node information from a user equipment (UE) to configure the relay node ID for the relay node in an aggregated group. The network node may schedule the operations of the devices of the aggregated group based on the configuration. The UE may detect the relay node and assign the relay node ID configured by the network node to the relay node in the aggregated group. Therefore, when the relay node in the aggregated group cannot directly obtain the relay node ID from the network node, the UE can assist of obtaining the relay node ID from the network node and assigning the relay node ID to the relay node in the aggregated group.

Abstract: A communications apparatus. A first radio module communicates with a first wireless network and provides wireless communication services in compliance with a first RAT. A second radio module communicates with a second wireless network and provides wireless communication services in compliance with a second RAT. At least two antennas are shared by the first radio module and the second radio module. When the first radio module operates in an idle mode and when the timing of the first radio module performing a first receiving activity coincides with the timing of the second radio module performing a second receiving activity, the second radio module uses the antennas to perform the second receiving activity when a DRX cycle duration of the first radio module in the idle mode is shorter than a DRX cycle duration of the second radio module.

The network node may generate the resource configuration for discovery procedure and allocate the resource configuration for discovery procedure to a UE. The UE may transmit the resource configuration for discovery procedure to at least one relay node. Thus, the relay node is able to obtain the resource configuration for discovery procedure from the UE.

Abstract: A synergetic communication method for capability reporting in relay communications is proposed. A user equipment (UE) may detect the relay node(s). In an event that a trigger condition is triggered, the UE may transmit the capability report associated with the detected relay node to the network node. The network node may generate the resource configuration based on the capability report from the UE. Therefore, the network node is able to obtain the capability information of the relay node even if the relay node has limited capability, e.g., the relay node is a layer 0 (L0) relay node or a layer 1 (L1) relay node.

Abstract: A communications apparatus includes a controller and a wireless communications module. The controller selects a first subset of receiving beam(s) from receiving beams supported by a wireless communications module. The wireless communications module uses the receiving beam(s) in the first subset in turns to receive signals transmitted by a network control device for a first stage of beam training. The network control device uses control beams in turns to transmit the signals. The controller further calculates a detection metric for each combination of the receiving beam(s) in the first subset and the control beams, and determines a preferred control beam and a preferred receiving beam according to the detection metrics for the first stage of beam training.
