Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of enhanced blind retransmission scheme. The method comprises: receiving, at a first device and from a second device, a configuration for determining a target offset associated with a contention resolution timer for a random access procedure; determining the target offset based on the configuration; transmitting, to the second device, a message associated with the random access procedure, the message comprising an identity of the first device for random access; and controlling a starting and termination of the contention resolution timer based on the target offset and the transmission of the message. In this way, the blind retransmission of MSG3 can be supported in the random access procedure through controlling a starting and termination of the contention resolution timer based on the transmission of the message and an offset, which is beneficial to the NTN.

Abstract: Various example embodiments relate to devices and methods for refining a coverage window for discontinuous coverage. A terminal device may comprise at least one processor and at least one memory including computer program code. The at least one memory and the computer program code may be configured to, with the at least one processor, cause the terminal device to perform actions including determining a coverage window for receiving transmission from a network device, monitoring radio coverage of the network device at least during the coverage window, and updating the coverage window based on when the radio coverage is available for the terminal device.

Abstract: Example embodiments of the present disclosure relate to repetition solution for transmission. In such solution, a first device determines information associated with a movement direction of a second device serving the first device relative to the first device. Then, the first device performs a transmission of the information to the second device. With this solution, repetition number is able to be selected/determined at both the first device and the second device based on the information such as change trend of pathloss/RSRP, the change trend of RSRP of a signal received from the second device, the change trend of a distance between the first device and the second device, the change trend of an elevation angle between the first device and the second device, the change trend of a SINR of a signal received from the second device, the change trend of RSRQ of a signal received from the second device, the change trend of a Doppler shift of a signal received from the second device, or elevation angle of the second device, thereby optimizing the resource usage of the network and reducing the transmission time as well as the power consumption for the first device or reducing the failure of the transmission.

Abstract: Embodiments of the present disclosure relate to conditional handover. A method comprises: determining, at a first device, an ordered list of target cells for a second device to initiate handover to in order based at least in part on location-related data of the second device, the second device being served in a source cell of the first device; transmitting, to the second device, first information indicating the ordered list of target cells and radio configurations associated with each of the target cells; and causing second information indicating the ordered list of target cells to be transmitted to at least one third device serving target cells in the ordered list, to request allocation of resources for the handover by the at least one third device. In this way, a chain of target cells regarding future handover is determined in a predetermined order, which avoid multiple cells prepare for a same handover, thus reducing handover preparation latency and improving the service continuity.
