A method comprising: determining at least one shortened physical downlink control channel monitoring set including shortened physical downlink control channel downlink control candidates to be monitored by a device in a shortened transmit time interval of a subframe, where the shortened transmit time interval is shorter in length than a subframe length transmit time interval, where a regular physical downlink control channel corresponds at least to downlink transmission of the subframe length transmit time interval, where the at least one shortened physical downlink control channel monitoring set spans a first set of orthogonal frequency division multiplexing symbols, and where a shortened physical downlink control channel corresponds at least to downlink transmission of a shortened transmit time interval; receiving, by the device from a network, a shortened physical downlink control channel belonging to one of the at least one shortened physical downlink control channel monitoring set, where the shortened physical downlink control channel schedules downlink data packet transmissions in a shortened physical downlink shared channel, and where the shortened physical downlink control channel also indicates an rate-matching indicator that indicates at least one orthogonal frequency division multiplexing symbol that does not belong to the first set of orthogonal frequency division multiplexing symbols; determining a set of frequency resources; and decoding the shortened physical downlink shared channel based on the set of frequency resources belonging to the at least one orthogonal frequency division multiplexing symbol indicated by the rate matching indicator being not available for the shortened physical downlink shared channel. determining at least one shortened physical downlink control channel monitoring set including shortened physical downlink control channel downlink control candidates to be monitored by a device in a shortened transmit time interval of a subframe, where the shortened transmit time interval is shorter in length than a subframe length transmit time interval, where a regular physical downlink control channel corresponds at least to downlink transmission of the subframe length transmit time interval, where the at least one shortened physical downlink control channel monitoring set spans a first set of orthogonal frequency division multiplexing symbols, and where a shortened physical downlink control channel corresponds at least to downlink transmission of a shortened transmit time interval; where the shortened transmit time interval is shorter in length than a subframe length transmit time interval, where a regular physical downlink control channel corresponds at least to downlink transmission of the subframe length transmit time interval, where the at least one shortened physical downlink control channel monitoring set spans a first set of orthogonal frequency division multiplexing symbols, and where a shortened physical downlink control channel corresponds at least to downlink transmission of a shortened transmit time interval; receiving, by the device from a network, a shortened physical downlink control channel belonging to one of the at least one shortened physical downlink control channel monitoring set, where the shortened physical downlink control channel schedules downlink data packet transmissions in a shortened physical downlink shared channel, and where the shortened physical downlink control channel also indicates an rate-matching indicator that indicates at least one orthogonal frequency division multiplexing symbol that does not belong to the first set of orthogonal frequency division multiplexing symbols; where the shortened physical downlink control channel schedules downlink data packet transmissions in a shortened physical downlink shared channel, and where the shortened physical downlink control channel also indicates an rate-matching indicator that indicates at least one orthogonal frequency division multiplexing symbol that does not belong to the first set of orthogonal frequency division multiplexing symbols; determining a set of frequency resources; and decoding the shortened physical downlink shared channel based on the set of frequency resources belonging to the at least one orthogonal frequency division multiplexing symbol indicated by the rate matching indicator being not available for the shortened physical downlink shared channel.
