摘要： The invention relates to radio link monitoring and when to change the radio link monitoring configuration for a client device (100). The client device (100) performs radio link monitoring for a radio link to a network access node (300) based on a measured quality of the radio link and a first set of parameters. The client device (100) further compares the measured quality of the radio link with a second set of parameters and indicates the comparison of the measured quality of the radio link with at least one parameter of the second set of parameters to the network access node (300). Based on the indication the network access node (300) can determine if the radio link can support a second service associated with the second set of parameters and transmit a first reconfiguration instruction to the client device (100) if the radio link can support the second service. The first reconfiguration instruction instructs the client device (100) to change from the first set of parameters to the second set of parameters for performing radio link monitoring for the radio link. Thereby, the network access node (300) can deliver data associated with the second service to the client device (100) over the radio link. Furthermore, the invention also relates to corresponding methods and a computer program.

摘要： The invention relates to efficient receive beam management and/or cell selection based on reporting of mobility information. A first network access node (100a) obtains mobility information associated with a network access node (100a; 100b) and transmits the mobility information to a client device (300). The mobility information may indicate if the network access node (100a; 100b) is a mobile network access node and if the network access node (100a; 100b) is currently moving or stationary, as well as a geographical location of the network access node (100a; 100b). The client device (300) may use the received mobility information associated with the network access node (100a; 100b) to perform receive beam management and/or cell selection towards the network access node (100a; 100b). Furthermore, the mobility information may be exchanged between network access nodes (100a, 100b).

摘要： The invention relates to a processing device (100) for a client device (300), the processing device (100) comprising a physical, PHY, layer (102), and a Medium Access Control, MAC, layer (104). The PHY layer (102) monitors a quality of a serving BPL (502) associated with a downlink control channel and determines a beam failure event for the serving BPL (502) based on the monitored quality. The PHY layer (102) further provides an indication of the beam failure event to the MAC layer (104). The MAC layer (104) stops, in response to reception of the indication of the beam failure event, at least one of: a timer associated with a scheduling request configuration, a counter associated with the scheduling request configuration, a time alignment timer, and a contention-based Random Access, RA, procedure except a contention-based RA procedure associated with a Beam Failure Recovery Request, BFRQ, transmission. The MAC layer (104) further receives a BFRQ transmission initiation from the PHY layer (102) or an indication of a Radio Link Failure, RLF, event at a Radio Resource Control, RRC, layer (106). Furthermore, the invention also relates to a client device (300) comprising the processing device (100), corresponding methods, and a computer program.

摘要： The invention relates to handling of data transmissions during measurement gaps. With a new control message (510), a network access node (100) can configure a client device (300) to skip measurement gaps and further receive data during the skipped measurement gap. Thus, when the network access node (100) transmits a data packet to the client device (300) during a measurement gap, the client device (300) can skip the measurement gap and instead receive the data packet during the measurement gap. Thereby, stringent latency and reliability requirements can be meet. Furthermore, the invention also relates to corresponding methods and a computer program.
