Abstract
A method of operating a first communication node includes receiving a communication at the first communication node from a second communication node, wherein the communication includes information bits in a plurality of information bit positions, determining, by the first communication node, a subset of the information bit positions of the communication that are punctured wherein the determining is performed based on detected or decoded control information, and responsive to determining the subset, reducing, by the first communication node, magnitudes of information bits in the subset of the information bit positions that are punctured.
Claims22
A method of operating a first communication node, the method comprising:
- receiving a communication at the first communication node from a second communication node, the communication including information bits in a plurality of information bit positions;
- determining, by the first communication node, a subset of the information bit positions of the communication that are punctured, the determining being performed based on detected or decoded control information;
- responsive to determining the subset, reducing, by the first communication node, magnitudes of information bits in the subset of the information bit positions that are punctured;
- determining at the first communication node an estimate of a modulation used in a search space;
- and
- the subset of the information bit positions that are punctured being determined responsive to determining that the estimate of the modulation is different than a signaled modulation that is signaled on a scheduling assignment from the second communication node.
A first communication node comprising:
- a transceiver configured to provide communication with a second communication node over a wireless interface;
- and
- a processor coupled with the transceiver, the processor being configured to provide reception/transmission from/to the second communication node through the transceiver, and the processor configured to perform operations comprising:
- receiving, from a second communication node, the communication including information bits in a plurality of information bit positions;
- determining a subset of the information bit positions of the communication that are punctured, the determining being performed based on detected or decoded control information;
- and
- responsive to determining the subset, reducing magnitudes of information bits in the subset of the information bit positions that are punctured;
- determining an estimate of a modulation used in a search space;
- and
- the subset of the information bit positions that are punctured being determined responsive to determining that the estimate of the modulation is different than a signaled modulation that is signaled on a scheduling assignment from the second communication node.
