The invention relates to a method in a user equipment and a user equipment (700) for controlling connection re-establishment between said user equipment and a network. The method comprises the steps of receiving (501) a configuration message from the network defining at least one condition; upon detection of connectivity problems (503) towards the first cell, evaluating said at least one condition (504); if said at least one condition is fulfilled for a neighboring cell (B), applying at least one special criterion for initiating connection re-establishment to said neighboring cell (505), said at least one special criterion being different from at least one criterion that is applied if said at least one condition is not fulfilled. The invention furthermore relates to a method and an arrangement in a network node (800) for controlling connection re-establishment between the network and a user equipment (700).

This application provides failure processing methods, handover methods, terminal devices, and network devices. One method includes receiving a radio resource control (RRC) configuration of a secondary network device, if the RRC configuration of the secondary network device is from the secondary network device and the RRC configuration fails, sending, to a primary network device, first indication information for indicating a configuration failure of the RRC configuration.

The present disclosure relates to handling a master cell group (MCG) failure in wireless communications. According to an embodiment of the present disclosure, a method performed by a wireless device in a wireless communication system comprises: receiving, from a source primary cell (PCell), a conditional mobility command including a mobility condition for a target PCell; starting a timer for a master cell group (MCG) failure recovery and transmitting MCG failure information related to the MCG failure recovery to a primary secondary cell (PSCell), based on detecting a radio link failure (RLF) on the source PCell; and based on that the mobility condition for the target PCell is satisfied while the timer is running: transmitting, to the PSCell, a new PCell indication informing a mobility from the source PCell to the target PCell; and performing a random access to the target PCell for the mobility.

Embodiments of the present application relate to methods and apparatuses for a mobility robustness optimization (MRO) mechanism of an inter-radio access technology (RAT) handover procedure. According to an embodiment of the present application, a method can include: receiving a mobility command message from a source new radio (NR) cell, wherein the mobility command message includes an identifier (ID) of a target cell, and the target cell is at least one of an evolved universal terrestrial radio access network (E-UTRAN) cell and an universal terrestrial radio access network (UTRAN) cell; determining whether a timer for initiating failure recovery based on triggering a measurement report (e.g., timer T312) is running; and in response to the timer being running, stopping the timer. Furthermore, radio link failure report (RLF) information is transmitted to a network in response to the failure of Inter-RAT handover from NR to E-UTRAN and UTRAN.

A terminal includes: a control unit configured to connect to another terminal in an RRC (Radio Resource Control) layer; and a transmitting unit configured to transmit data to the another terminal. In a case where the another terminal or the terminal itself performs at least one of transmission, reception, and sensing during a specific timing, the control unit controls an operation related to the connection in the RRC layer, based on the specific timing.

A wireless device receives one or more configuration parameters indicating a first beam detection set including a first reference signal and a second beam detection set including a second reference signal. The first reference signal overlaps in at least one symbol with the second reference signal. The wireless device measures, for beam failure and in response to the first beam detection set being different from the second beam detection set, both the first reference signal and the second reference signal.
