摘要： A client device and a corresponding method for detecting and indicating that a Quality-of-Service (QoS) estimate for a radio link serving an application does not fulfill a QoS requirement associated with the application is provided. The 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. According to the application, the client device is allowed to take precautionary actions to counteract possible negative consequences of the non-fulfillment of the QoS requirement.

摘要： In certain embodiments, a method includes generating a first signal and a second signal. The first signal includes at least one first sub-signal, and the second signal includes at least one second sub-signal. A subcarrier frequency spacing of the first sub-signal is M times as large as a subcarrier frequency spacing of the second sub-signal. The method further includes separately sending each first sub-signal and each second sub-signal. In a range of a first preset frequency apart from a reference subcarrier frequency, all the second sub-signals sent on a subcarrier corresponding to a subcarrier frequency whose difference from the reference subcarrier frequency is a non-integer multiple of the subcarrier frequency spacing of the first signal are zero signals. The reference subcarrier frequency is a subcarrier frequency of the first sub-signal adjacent to the second signal in a frequency domain.

摘要： The present disclosure relates to client devices and methods for link failure recovery in discontinuous reception (DRX) in connected mode (C-DRX). One example client device is configured to perform beam/link monitoring according to a link recovery procedure if the client device is in a C-DRX mode operation with a network access node, where a configured beam failure detection (BFD) timer of the link recovery procedure is a function of a periodicity of beam failure indications.

摘要： Method is provided, including: determining, by a base station, a current time period in which an end moment of a current control channel is located in a first transmission time interval (TTI), where the first TTI includes at least two time periods, and a start moment of a data channel corresponding to a control channel that ends in each of the at least two time periods is located in a different TTI; sending, by the base station to user equipment in the first TTI, control information carried on the current control channel, where the control information is configured to schedule a current data channel corresponding to the current control channel; determining, by the base station, a second TTI in which a start moment of the current data channel is located; and exchanging, by the base station, data of the current data channel with the user equipment in the second TTI.

摘要： The application relates to maintaining time-synchronization of a wireless connection between a network access node and a client device. The wireless connection may be configured for services with latency constraints. In one example, based on an expiry of a time alignment timer for the client device, the network access node transmits a control message to the client device. The control message instructs the client device to transmit a response signal to the network access node. The response signal can be used by the network access node to determine the timing advance for the wireless connection and adjust the timing advance.

摘要： Embodiments of the present disclosure provide a data transmission method and apparatus. The method includes sending, by a base station to UE, a downlink control channel used to schedule downlink data. The method further includes indicating, by the base station, a first time-frequency resource domain and a second time-frequency resource domain using the downlink control channel. A downlink data channel is sent on a time-frequency resource that is in the first time-frequency resource domain and that does not belong to the second time-frequency resource domain.

摘要： It is an object to provide a procedure for handling failure of a subset of serving beam pair links in wireless radio communication. A client device is configured to monitor, independently, a link quality of each serving downlink (DL) beam pair link (BPL) of the client device; detect at least one failed DL BPL based on the monitoring, where the at least one failed DL BPL is a subset of the monitored serving DL BPLs; choose an uplink, UL, BPL, where the chosen UL BPL corresponds to an available serving DL BPL of the monitored serving DL BPLs; and transmit a beam report within a predetermined time period from the detection through a non-contention-based channel using the chosen UL BPL, where the beam report indicates the at least one failed DL BPL. A client device, a network device, methods and a computer program are included.
