摘要： Various example embodiments relate to uplink synchronization. An apparatus may receive, from a device, an alert of expected expiry of at least one validity period of uplink synchronization data. In response to receiving the alert, the apparatus may pause scheduling of data transmissions for the device, or transmit, to the device, an on-demand uplink synchronization assistance signal comprising updated uplink synchronization data.

摘要： Based on a configuration of a pre-allocated sequence of first SSBs of a first predetermined number, which comprise second SSBs of a second predetermined number and third SSBs of a third predetermined number, a network apparatus of an access network of a cellular communication system determines (S503) a usage for resources associated with the third SSBs. According to the configuration of the pre-allocated sequence of first SSBs, the second SSBs are to be utilized in a beam management procedure including an initial access procedure and the third SSBs are not necessarily to be utilized in the beam management procedure including the initial access procedure which enables UEs to gain initial access to the cellular communication system via the access network. The network apparatus broadcasts (S505) the usage in the beam management procedure.

摘要： A method includes receiving, from a base station, network signaling including information about one or more of a timing advance scaling parameter, a processing-delay compensation parameter, and a timing advance extension parameters enabling threshold/condition; receiving a timing advance index from the base station; adjusting parameters for uplink transmissions using the received timing advance index for the one or more of the timing advance scaling parameter, the processing-delay compensation parameter, and the timing advance extension parameters enabling threshold/condition; and performing uplink transmissions according to the configured and adjusted parameters. Another method includes sending, to a user equipment, network signaling including information about one or more of a timing advance scaling parameter, a processing-delay compensation parameter, and a timing advance extension parameters enabling threshold/condition; sending a timing advance index to the user equipment; and receiving uplink transmissions according to the configured and adjusted parameters.

摘要： One embodiment is directed to a method comprising receiving a grant message for channel resource allocation from a scheduling node, receiving data transmission based on the allocated channel resource from the scheduling node, and receiving a confirmation message from the scheduling node that indicates which channel resource was actually used for the data transmission. Another embodiment is directed to a method comprising receiving a grant message for channel resource allocation, receiving data transmission based on the allocated channel resource, decoding the received data, if the received data cannot be decoded correctly, sending an indication of packet failure, receiving a retransmission grant message, receiving a retransmitted data, and based on the retransmission grant message, performing HARQ combining.

摘要： An approach is provided for network-based positioning in non-terrestrial networks. The approach, for example, involves receiving a downlink position reference signal from a network node of a non-terrestrial network. The approach also involves determining whether the user device is in either line-of-sight or non-line-of-sight with respect to a network node of a non-terrestrial network. The approach further involves performing at least one of: (a) based on determining that the user device is in line-of-sight, transmitting a sounding reference signal for positioning to the network node; and (b) based on determining that the user device is in non-line-of-sight, transmitting the sounding reference signal for positioning to the network node for a number of repetitions.
