Abstract
Embodiments of the present disclosure relate to methods, devices and computer readable media for transmission and reception of DCI in a single carrier based downlink control channel. A method of communication comprises receiving, at a terminal device, a reference signal for a downlink control channel associated with the terminal device via a first time-frequency resource allocated for transmission of the reference signal; determining, from a set of second time-frequency resources allocated for the downlink control channel, a subset of second time-frequency resources based on the reference signal; and receiving DCI via the subset of second time-frequency resources. The method further comprises determining, at a network device, the first and second time-frequency resources; determining the reference signal based on the second time-frequency resource; and transmitting the reference signal and DCI via the first and second time-frequency resources respectively. Embodiments of the present disclosure can reduce the complexity on blind detection for the downlink control channel while supporting low PAPR and better coverage with a single carrier based downlink control channel structure.
