The present invention relates to a mobile terminal which comprises a mobile telephone and an additional device. In this case, the additional device comprises a second communication module, wherein the second communication module is designed such that it enables, as a participant of a WLAN network, a wireless third communication connection to this WLAN network.

A method is performed at a first multilink device configured to communicate wirelessly with a first radio and a second radio of a second multilink device. The method includes accessing a set of parameters for a known mathematical model that establishes a frequency separation to be imposed between transmission from the first radio and reception at the second radio in order to achieve a predetermined reception performance at the second radio when the transmission and the reception are simultaneous. The method further includes, using the known mathematical model, computing the frequency separation based on the set of parameters.

This application provides a method for signal reception and transmission in a measurement gap. User equipment (UE) obtains, in dual connectivity, a measurement configuration delivered by a base station, and determines a first cell group in which signal reception and transmission can be performed in the measurement gap; performs signal reception and transmission with the base station in the first cell group in the measurement gap; and performs inter-frequency or inter-RAT measurement in a second cell group. The second cell group is a cell group in which signal reception or transmission cannot be performed in the measurement gap. In the measurement gap, the base station and the UE can still receive and transmit signals in the first cell group, and radio frequency channels of the UE that support signal reception and transmission in the measurement gap can be fully used for performing signal reception and transmission.
