Abstract: Aspects are described for a user equipment (UE) comprising two or more transceivers configured to enable wireless communication with a first base station, and a processor communicatively coupled to the two or more transceivers. The processor is configured to measure a first reference signal and a second reference signal during a measuring period to determine a first measuring result of the first reference signal and a second measuring result of the second reference signal. The processor is further configured to generate one or more reports that include the first measuring result and the second measuring result, wherein the one or more reports indicate that the first measuring result is associated with the second measuring result in time. The processor is further configured to transmit the one or more reports to the first base station.

Abstract: Embodiments of the present disclosure relate to multi-path operation. According to embodiments of the present disclosure, a measurement report is transmitted to a base station on a first path between the UE and the base station, wherein the measurement report indicates channel quality information on one or more potential paths between the UE and the base station. A path addition command is then received from the base station, wherein the path addition command indicates the UE to add a path from one or more potential paths as a second path. The second path between the UE and the base station is then established based on the path addition command.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for prioritizing data transmissions. According to embodiments of the present disclosure, in accordance with a determination that there is an overlap between a configured uplink grant and a dynamic uplink grant, a terminal device selects, from the configured uplink grant and the dynamic uplink grant, a target uplink grant for transmitting data to a network device. Thereby, the terminal device transmits data to the network device via the target uplink grant.
