Abstract

See full text

The solution presented herein introduces variable repetition levels for control and data transmissions via a physical downlink control channel for machine-type communications, e.g., the M-PDDCH. When a wireless terminal detects and correctly decodes a message carried by physical downlink control channel for machine-type communications that requests retransmissions, the wireless terminal performs adaptive uplink retransmissions according to a retransmission format defined by the message. The retransmission format defines at least one of a modulation and coding rate for the retransmissions, a frequency resource for the retransmissions, and a number of repetitions.
