ENB PDCCH implementation to avoid ambiguous DCI information
First Claim
1. A method of wireless communication, comprising:
- determining a first starting index for transmitting a first control message in a first search space;
determining a second starting index for transmitting a second control message in a second search space; and
when the first starting index and the second starting index have the same value;
determining at least one information field different between the first control message and the second control message,determining whether the at least one different information field in the second control message would have a different interpretation when decoded based on the first search space than when decoded based on the second search space, andsetting a bit of the at least one different information field to zero in the second control message when the at least one information field in the second control message would have a different interpretation when decoded based on the first search space than when decoded based on the second search space.

Abstract
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines a first starting index for transmitting first control information in a first search space, determines a second starting index for transmitting second control information in a second search space, and transmits the second control information in the second search space at the second starting index when the first starting index and the second starting index are not the same value. The apparatus further transmits to a user equipment (UE) control information in a first search space, receives information from the UE corresponding to the transmitted control information, and decodes the received information based on the UE parsing the control information according to the first search space and based on the UE incorrectly parsing the control information according to a second search space.

11. An apparatus for wireless communication, comprising:
-
a memory; and at least one processor coupled to the memory and configured to; determine a first starting index for transmitting a first control message in a first search space; determine a second starting index for transmitting a second control message in a second search space; and when the first starting index and the second starting index have the same value; determine at least one information field having a respective bit different between the first control message and the second control message, determine whether the at least one different information field in the second control message would have a different interpretation when decoded based on the first search space than when decoded based on the second search space, and set a bit of the at least one different information field to zero in the second control message when the at least one information field in the second control message would have a different interpretation when decoded based on the first search space than when decoded based on the second search space. - View Dependent Claims (12, 13, 14, 15)

16. A non-transitory computer-readable medium storing computer executable code, comprising code for:
-
determining a first starting index for transmitting a first control message in a first search space; determining a second starting index for transmitting a second control message in a second search space; and when the first starting index and the second starting index have the same value; determining at least one information field having a respective bit different between the first control message and the second control message, determining whether the at least one different information field in the second control message would have a different interpretation when decoded based on the first search space than when decoded based on the second search space, and setting a bit of the at least one different information field to zero in the second control message when the at least one information field in the second control message would have a different interpretation when decoded based on the first search space than when decoded based on the second search space. - View Dependent Claims (17, 18, 19, 20)
