    摘要: Systems and methods are disclosed herein for control resource set (CORESET) enhancements that are particularly beneficial for reduced bandwidth wireless communication devices. Embodiments of a method performed by a wireless communication device for a cellular communications system are disclosed. In one embodiment, a method performed by a wireless communication device for a cellular communications system comprises receiving, from a network node, information that configures a CORESET for the wireless communication device, the CORESET comprising four or more symbols in the time domain. The method further comprises receiving a physical downlink control channel (PDCCH) transmission from the network node within a search space that comprises at least a subset of time-frequency resources within the CORESET. In this manner, the CORESET is enhanced in a way that is particularly beneficial for reduced bandwidth wireless communication devices. Corresponding embodiments of a network node are also disclosed.

    摘要: Apparatuses and methods are disclosed for wireless device (WD) grouping indication using a wake-up signal (WUS). In one embodiment, a method in a WD includes receiving a WUS associated with a paging occasion (PO) of the WD; and based on a grouping indication of the WUS, determining whether the WUS corresponds to at least one WD group that the WD belongs to. In another embodiment, a method in a network node includes configuring a WUS with a grouping indication, the WUS associated with a PO for a wireless device, and the grouping indication indicating at least one WD group that the WD belongs to; and transmitting the WUS according to the grouping indication.

    摘要: The present disclosure relates to methods and devices for synchronizing one or more radio devices with a radio access node. A method of providing synchronization with a radio access node for radio communication to one or more radio devices is disclosed. The method comprises or triggers transmitting a configuration message to at least one of the radio devices, where the configuration message is indicative of a synchronization signal configuration for a configurable synchronization signal. The method further comprises or triggers transmitting the configurable synchronization signal to the at least one radio device in accordance with the synchronization signal configuration and communicating one or more decodable signals between the radio access node and the at least one radio device using radio resources in accordance with the configurable synchronization signal. A corresponding method of synchronizing the radio device with the radio access node for radio communication is disclosed.
