Resource index determination for bundled channel transmission in special subframes

An apparatus for wireless communications, comprising:

• means for determining a channel is scheduled to be repeated across a bundle of subframes;
• means for determining a beginning subframe of the bundle of subframes is of a special subframe type that does not support repetition of the channel and in which the channel is dropped, wherein the special subframe type comprises a subframe with one of a special subframe configuration 1, 2, 6, 7, or 9;
• means for determining enhanced control channel elements (ECCE) indices for one or more decoding candidates of the channel in one or more other subframes of the bundle of subframes, wherein:
• the means for determining the ECCE indices comprises means for determining the ECCE indices using a hashing function that is based on a subframe number of the beginning subframe and a number of enhanced resource element groups (EREGs) per ECCE,
• the number of EREGs per ECCE used in the hashing function is a predetermined value associated with a normal subframe type when the beginning subframe is of the special subframe type in which the channel is dropped, and
• the predetermined value includes a value of 4 for a normal cyclic prefix (NCP) and a value of 8 for an extended cyclic prefix (ECP);
• and
• means for monitoring the one or more decoding candidates on the determined ECCE indices.

An apparatus for wireless communications, comprising:

• at least one processor configured to:
• determine a channel is scheduled to be repeated across a bundle of subframes;
• determine a beginning subframe of the bundle of subframes is of a special subframe type that does not support repetition of the channel and in which the channel is dropped, wherein the special subframe type comprises a subframe with one of a special subframe configuration 1, 2, 6, 7, or 9;
• determine enhanced control channel elements (ECCE) indices for one or more decoding candidates of the channel in one or more other subframes of the bundle of subframes, wherein:
• the at least one processor is configured to determine the ECCE indices using a hashing function that is based on a subframe number of the beginning subframe and a number of enhanced resource element groups (EREGs) per ECCE,
• the number of EREGs per ECCE used in the hashing function is a predetermined value associated with a normal subframe type when the beginning subframe is of the special subframe type in which the channel is dropped, and
• the predetermined value includes a value of 4 for a normal cyclic prefix (NCP) and a value of 8 for an extended cyclic prefix (ECP);
• and
• monitor the one or more decoding candidates on the determined ECCE indices.
