Abstract: Embodiments of the present disclosure relate to methods, devices and apparatuses of processing beam failure of a secondary cell at a terminal device and a network device respectively. In an embodiment of the present disclosure, the terminal device is serviced in a primary cell and a secondary cell on separate beams, and the secondary cell operates in a self-scheduling mode. The method may include transmitting, on an uplink control channel of the primary cell, a beam failure recovery request of the secondary cell, in response to detection of a beam failure in the secondary cell; and receiving a response to the beam failure recovery request of the secondary cell on a downlink control channel of the primary cell, wherein the response is configured to indicate a transmission configuration indication for a subsequent transmission. With embodiments of the present disclosure, a solution for supporting beam failure recovery request in the secondary cell without substantial latency or overhead issues, which makes an efficient beam failure recovery in the secondary cell possible.

Abstract: Embodiments of the present disclosure relate to methods and apparatuses for downlink control information (DCI) transmission and receiving in a wireless communication system. A DCI configuration parameter can be first transmitted to a terminal device; and then DCI is transmitted to the terminal device, wherein the DCI configuration parameter indicates time-frequency resources for the DCI. With embodiments of the present disclosure, the UE could perform a flexible DCI monitoring according to the DCI configuration parameter and thus it may support the DCI monitoring occasion change due to numerology and scheduling unit size.

Abstract: Embodiments of the present disclosure relate to methods, devices and apparatus for resource allocation for a control resource region in a wireless communication system. In an embodiment of the present disclosure, a method may include determining resource units each containing a predetermined number of resource blocks based on available transmission resources. Resource blocks not contained in the resource units are distributed in the available transmission resources to divide resource blocks contained in the resource units into a plurality of resource segments. The method also comprise allocating one or more of the determined resource units to the control resource region and transmitting resource allocation information indicating the allocated one or more of resource units. With embodiments of the present disclosure, there is provided an effective solution for resource allocation for control resource region.

Abstract: Embodiments of the present disclosure relate to methods and apparatuses for Control State Information (CSI) transmission. In example embodiments, a method implemented in a terminal device is provided. According to the method, in response to receiving DCI from a network device, a configuration for transmitting CSI to the network device is determined at least based on the DCI. The DCI indicates a CSI-RS for determining the CSI and timing information associated with the CSI. The CSI is determined by measuring the CSI-RS in response to receiving the CSI-RS from the network device. The CSI is transmitted to the network device based on the configuration.
