Abstract
A method and apparatus provide reception of control signaling in a wireless communication network. Downlink Control Information (DCI) containing PDSCH resource assignments can be received in one of two types of control channels in a subframe. A type of truncation of the subframe can be determined based on the type of control channel on which the DCI is received. The PDSCH can be decoded based on at least the determined type of truncation of the subframe.
Claims24
A method in a device, the method comprising:
- receiving downlink control information containing physical downlink shared channel resource assignments in one of two types of control channels in a subframe;
- determining a type of truncation of the subframe based on the type of control channel on which the downlink control information is received;
- and
- decoding the physical downlink shared channel based on at least the determined type of truncation of the subframe.

An apparatus comprising:
- a transceiver configured to receive downlink control information containing physical downlink shared channel resource assignments in one of two types of control channels in a subframe;
- and
- a controller configured to determine a type of truncation of the subframe based on the type of control channel on which the downlink control information is received and configured to decode the physical downlink shared channel based on at least the determined type of truncation of the subframe.
A method in a first device, the method comprising:
- communicating with second device using a primary serving cell operating on a licensed carrier and a secondary serving cell operating on an unlicensed carrier;
- receiving downlink control information containing physical downlink shared channel resource assignments in one of two types of control channels in a subframe from the second device;
- ascertaining a type of subframe truncation is a back truncation if the downlink control information is received in a physical downlink control channel;
- ascertaining the type of subframe truncation is a front truncation if downlink control information is received in an enhanced physical downlink control channel;
- and
- attempting to decode a physical downlink shared channel from the second device based on at least the ascertained type of truncation of the subframe.
