Abstract: 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.

Abstract: Methods, apparatuses, and computer software products for paging, the method comprises: dividing paging occasions within at least one discontinuous reception cycles or within a paging time window of an extended discontinuous reception cycle into multiple paging occasion subgroups based on user equipment characteristics, and broadcasting the multiple paging occasion subgroups in system information (S101); receiving a paging message from a network element, identifying a paging occasion subgroup corresponding to a user equipment to be paged from the multiple paging occasion subgroups and selecting a paging occasion corresponding to the user equipment from the paging occasion subgroup according to the paging message (S103); transmitting a group based wake up signal associated with the paging occasion prior to the paging occasion if the user equipment currently uses group based wake up signal (S104).

Abstract: Various communication systems may benefit from proper handling of mobility. In particular, connected mode mobility may be suitably addressed for enhanced coverage user equipment. A method can include determining to attempt access to a target cell in enhanced coverage mode. The method can also include sending, based on the determination, a report to a source cell of an intent to access the target cell in enhanced coverage mode.
