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: Methods and apparatus in a fifth-generation wireless communications network, including an example method, in a wireless device, that includes determining a reporting quality threshold for a parameter related to channel state information (CSI); performing a measurement for each of a plurality of beams from a first predetermined set of beams for evaluation; evaluating the measurement for each of the plurality of beams against the reporting quality threshold; discontinuing the performing and evaluating of measurements in response to determining that the reporting quality threshold is met for one of the beams, such that one or more beams in the first predetermined set of beams are not measured and evaluated; and reporting, to the wireless communications network, CSI for the one of the beams.

摘要: A UE transmits a radio access capability to a base station. The radio access capability is transmitted via an information element that comprises a bitmap in which a bit has a value that indicates, to the base station, support of a modification to at least one of a maximum power reduction or a spectrum emission requirement. According to embodiments, the base station manages the UE based on the supported modification. Such managing of the UE may include, for example, one or more of admission control, imposing scheduling restrictions, and imposing handover restrictions.

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.

摘要: Systems and methods are disclosed for adjusting Radio Link Monitoring (RLM), Radio Link Failure (RLF) detection, RLF recovery, and/or connection establishment failure detection for wireless devices (16) in a cellular communications network (10) depending on mode of operation. In one embodiment, a node (14, 16) in the cellular communications network (10) determines whether a wireless device (16) (e.g., a Machine Type Communication (MTC) device) is to operate in a long range extension mode of operation or a normal mode of operation. The node (14, 16) then applies different values for at least one parameter depending on whether the wireless device (16) is to operate in the long range extension mode or the normal mode. The at least one parameter includes one or more RLM parameters, one or more RLF detection parameters, and/or one or more RLF recovery parameters. In doing do, signaling overhead and energy consumption within the wireless device (16) when operating in the long range extension mode is substantially reduced.

摘要: A communication device is arranged for three main communication states: a detached state, an idle state, and an active state. The communication device connects to the cellular communication network such that a transition from the detached state to any of idle state or active state is made, performs scheduled operations in the active state or idle state, determines, when a transition from the active state to the idle state occurs, a time instant for a next operation in the active state, disconnects from the cellular communication network such that a transition to the detached state is made, and, when the time for next operation in the active state is approaching, connects to the cellular communication network again. A transceiver and a computer program are also disclosed.
