Abstract: According to embodiments of the present disclosure, a first device receives first information from a second device. The first information is associated with a conditional handover through a source Integrated Access Backhaul (IAB) node to a target IAB node. If the conditional handover is completed at an ancestor IAB node, the first device transmits, to the second device, second information associated with the conditional handover. In this way, it avoids the child IAB node performs the handover before its parent IAB node.

Abstract: Embodiments of the present disclosure provide a solution for supporting a successful handover report. In a method for communication, a terminal device receives, from a first network device providing a first cell, an indication that a handover of the terminal device from the first cell to a second cell of a second network device is to be performed. Then, the terminal device determines triggering information about a successful handover report of the handover based on a set of triggering conditions. The triggering information indicates whether the successful handover report is triggered for the handover. In this way, the successful handover report can be optionally triggered based on the set of triggering conditions, so that the terminal device may be limited to reporting a successful handover report when necessary, thereby saving processing resources and communication resources for unnecessary successful handover reports.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A terminal device receives, from a network device, a first timing value set associated with a first HARQ feedback with a first priority, a second timing value set associated with a second HARQ feedback with a second priority different from the first priority, and a TDRA list for the first and second HARQ feedbacks, determines a third timing value set from the first and second timing value sets, constructs a HARQ codebook comprising the first and second HARQ feedbacks at least based on the third timing value set and the TDRA list, and transmits the HARQ codebook to the network device on an uplink control channel. In this way, unnecessary redundancy in HARQ bits can be removed and UCI overhead can be reduced.

Abstract: Embodiments of the present disclosure relate to methods for communication, terminal devices, network devices and computer readable media. In the method, a terminal device determines a transmission configuration indicator (TCI) state for a physical downlink control channel (PDCCH) candidate, based on at least one of: an index of the PDCCH candidate, and an index of a control channel element (CCE) of the PDCCH candidate. The terminal device monitors the PDCCH candidate based on the TCI state. As a result, the complexity of the terminal device for blind detection or decoding is able to be reduced.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable mediums for beam management. In example embodiments, a method implemented at a first network device is provided. According to the method, a first group of resources are determined to be used by a terminal device for determining a first group of beams from the first network device. The first group of resources are different from a second group of resources configured by a second network device to the terminal device for determining a second group of beams from the second network device. The first group of resources are configured to the terminal device. A plurality of synchronization and/or reference signals are transmitted, using the first group of beams, on the first group of resources to the terminal device.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. According to embodiments of the present disclosure, the terminal device performs a cyclic shift on a sequence of uplink control information. The terminal device further performs an orthogonal spread on the sequence with the cyclic shift. The terminal device transmits the processed sequence to the network device. In this way, it avoids wasting transmission resources for DMRS. Further, it also avoids too complicated sequence detections.
