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 efficient beam management in communication devices based on reporting of Line-of-Sight characteristics. A first communication device (100) determines a Line-of-Sight characteristic associated with a first transmit beam received from a second communication device (300). The first communication device (100) can perform receive beam management, e.g. select a receive beam to use for receiving further transmissions from the second communication device (300), based on the determined Line-of-Sight characteristic. Furthermore, the first communication device (100) may report the determined Line-of-Sight characteristic associated with the first transmit beam to the second communication device (300). The second communication device (300) may use the reported Line-of-Sight characteristic associated with the first transmit beam to perform transmit beam management, e.g. to select a transmit beam to use for further transmissions to the first communication device (100).

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 link reconfiguration of a radio link configured for two different service types. A client device (100) receives data associated with a first service type and data associated with a second service type transmitted in a first transmit beam from a network access node (300) over a radio link (502). The client device (100) evaluates the quality of the first transmit beam based on two quality threshold values, a first quality threshold value associated with the first service type and a second quality threshold value associated with the second service type. Based on the evaluation of the quality of the first transmit beam, the client device (100) transmits an indication associated with reconfiguration of the radio link (502) to the network access node (300). The indication informs the network access node (300) about the quality of the first transmit beam relative to the first service type and the second service type. Thereby, the network access node (300) can perform suitable link reconfiguration actions for the radio link (502). Furthermore, the invention also relates to the network access node (300), corresponding methods and a computer program.
