Abstract: When a user equipment detects a condition that a distance between the user equipment, which has an established connection with a network entity of a communications network system, and a subject enters apre-warning region, the user equipment enters a monitoring mode based on at least the detected condition. In the monitoring mode, options of operations to be performed by the user equipment to mitigate degradation of the established connection due to a required power backoff of an antenna of the user equipment are monitored.

Abstract: The present disclosure relates generally to the field of wireless communications, and in particular to techniques for performing one-step data transmissions from a User Equipment (UE) to a Base Station (BS), without requiring the UE to transit from an idle state to a connected state in a wireless communication network. To make it possible to perform the one-step data transmission, the UE receives a confirmation from the BS that the BS supports the one-step data transmission (which means that the BS has allocated, in advance, the UL resources for performing the one-step data transmission), and to have a pre-stored database associating cell IDs of different cells with corresponding pre-allocated UL resources and transmission parameters. Said confirmation from the BS may be represented by a predefined signal sequence, the presence of which will inform the UE about the possibility of performing the one-step data transmission within a cell of interest. After receiving the predefined signal sequence, the UE uses the pre-stored database to find the UL resources and transmission parameters used for the one-step data transmission from the idle state within the cell of interest.
