Embodiments of the present disclosure relate to communications with preconfigured uplink resources (PUR). A method implemented at a terminal device comprises identifying a need to change a transmission configuration of the terminal device, the terminal device being in a transmission mode with a set of preconfigured uplink resources (PURs) allocated for the terminal device to transmit user data to a network device; and in response to identifying the need to change the transmission configuration, transmitting control information to the network device using a first PUR in the set of PURs, the control information comprising information relevant to the change of the transmission configuration. In this way, it is possible to enable the terminal device to save power, time, and resources by bypassing a full random access procedure when the transmission configuration is needed to be changed.

A UE receives configuration from a source cell for conditional handover for target cell(s). At least one of the target cell(s) also supports DAPS handover. The UE determines that either a RLF or HOF has occurred. The UE selects one of the target cell(s) for a handover, and performs a process for handover to the selected target cell. A UE receives individual handover commands and corresponding configuration for conditional handover for target cell(s) and an indication to use DAPS handover if possible in response to a handover. The UE determined condition(s) for handover to one of the target cell(s) have triggered, wherein the one target cell supports DAPS handover. The UE performs, based on the indication to use DAPS handover if possible in response to a handover, handover by the user equipment to the one target cell without releasing the source cell while accessing the one target cell.
