Abstract

According to some embodiments, a method for use in a wireless transmitter of a wireless communication network comprises providing control information relating to a slot. The control information includes an indication of whether the slot is of a first type or a second type. A slot of the first type starts at a slot interval boundary, and a slot of the second type either starts between slot interval boundaries and has arbitrary length or starts at a slot interval boundary and has reduced length. The control information includes an implicit or explicit reference signal timing indication if the slot is of the second type. The method further comprises transmitting the control information to a wireless receiver.

Dependent claims

A method for use in a wireless transmitter of a wireless communication network, the method comprising:

transmitting, to a wireless receiver of the wireless communication network, downlink control information (DCI) scheduling physical uplink shared channel (PUSCH) transmission in a slot, the downlink control information including:
a parameter indicating whether the slot is of a first type or a second type;
and
when the slot is of the second type, the parameter further indicating a reference signal timing;
wherein:
a slot of the first type corresponds with a prescheduled slot interval;
and
a slot of the second type either starts between prescheduled slot interval boundaries or starts at a prescheduled slot interval boundary, a length of the slot of the second type corresponding to a prescheduled number of symbols that is less than that of the prescheduled slot interval.
