摘要： The length and starting point of transmissions within a predetermined slot are adjusted, based on an expected accuracy of channel estimation performed by a receiving device. In an example, a scheduling node, which may be the receiving device or a transmitting device, allocates resources by evaluating (610) one or more parameters corresponding to a link between the transmitting device and the receiving device, the one or more parameters being predictive of channel estimation accuracy in the receiving device, and allocating (630) resources for a transmission from the transmitting device to the receiving device. This allocating comprises allocating a transmission interval so as to occupy fewer than all Orthogonal Frequency-Division Multiplexing (OFDM) symbols of a predetermined transmission slot and further comprises determining the number of OFDM symbols in the allocated transmission interval and/or the starting point of the allocated transmission interval within the predetermined transmission slot, based on said evaluating.
