Abstract: This application discloses a control information sending method, a data block transmission method, and a related apparatus. The control information sending method in this application is used to schedule multiple transmission time intervals TTIs for data transmission, and the multiple TTIs include at least a first TTI and a second TTI. The method includes: generating first control information, where the first control information is partial control information required for scheduling each of the multiple TTIs; generating second control information, where the second control information is remaining control information, other than the first control information, in complete control information for scheduling the first TTI; and generating third control information, where the third control information is partial control information required for scheduling the second TTI, where the first control information and the third control information are corresponding to complete control information required for scheduling the second TTI.

Abstract: Example methods and client devices and network access nodes for link failure recovery in connected-mode-discontinuous-reception (C-DRX) mode are described. In one example method, the client device performs beam/link monitoring according to a first link recovery procedure if the client device is in non-discontinuous-reception (non-DRX) mode operation with a network access node. The client device performs beam/link monitoring according to a second link recovery procedure if the client device is in C-DRX mode operation with the network access node.

Abstract: The present disclosure relates to wireless communications technologies, and in particular, to a network device, user equipment, and a system information transmission method. In embodiments of the present disclosure, for user equipments of different coverage grades within a coverage area of a cell, a network device uses different sending parameters to send pieces of system information. When receiving a piece of system information, user equipment first determines a coverage grade of the user equipment within the cell, and receives, in a receiving manner that matches a sending parameter used by the network device to send the system information at the determined coverage grade to which the user equipment belongs, the system information sent by the network device. The network device uses different sending parameters for different coverage grades. This ensures receipt of pieces of system information by user equipments belonging to different coverage grades.

Abstract: The invention relates to detecting and indicating that a QoS estimate for a radio link serving an application does not fulfill a QoS requirement associated with the application. A client device monitors QoS estimates for a radio link serving an application in the physical layer. The monitoring is based on a QoS monitoring configuration associated with the application. Upon detecting that a QoS estimate does not fulfill a QoS requirement obtained from the QoS monitoring configuration, the client device provides a first indication to a second layer arranged above the physical layer. The first indication provides an early warning that the radio link does not fulfill the QoS requirement. Thereby, allowing the client device to take precautionary actions to counteract possible negative consequences of the non-fulfillment of the QoS requirement. Furthermore, the invention also relates to corresponding methods and a computer program.

Abstract: The invention relates to a processing device (200) for a client device (100), the processing device (200) obtains a set of reference signal configurations for a set of serving downlink beams (502a, 502b, . . . , 502n), wherein each reference signal configuration of the set of reference signal configurations is associated with a respective serving downlink beam of the set of serving downlink beams (502a, 502b, . . . , 502n), and wherein each reference signal configuration of the set of reference signal configurations comprises a reference signal periodicity. The processing device (200) further performs beam monitoring on the set of serving downlink beams (502a, 502b, . . . , 502n) based on the reference signal periodicities of the set of reference signal configurations. Furthermore, the invention also relates to a client device (100) comprising the processing device (200), corresponding methods, and a computer program.

Abstract: The disclosure relates to performing phase compensation at a transmitter. A processing device for a network access node generates a phase compensated modulation symbol based on at least one first modulation symbol and at least on one of a frequency offset parameter and a time offset parameter. The frequency offset parameter may be determined based on an offset between a reference frequency f0 and a DC (0 Hz) frequency such that the frequency offset parameter corresponds to the reference frequency f0. Also, the reference frequency f0 can be at least partly based on the carrier of up-conversion frequency used by the processing device and the reference frequency f0 can be the carrier for up-conversion frequency. The phase compensated symbol is transmitted to a receiver, such as a client device. Furthermore, the disclosure also relates to corresponding methods and a computer program.
