i. In 1-a of Step 3, the symbol offsets O1 and O2 may be set to positive and/or negative integer values including “0”.
ii. For example, the symbol index E may be indicated as one of the following: 1) the symbol index S and 2) the symbol index L. Alternatively, the symbol index E may be determined as one of the symbol indices without separate signaling.
iii. As another example, the symbol index E may be indicated as one of the following: 1) a symbol index S?1, 2) the last symbol index in the slot, 3) the symbol index S, and/or 4) a symbol index S+1. Alternatively, the symbol index E may be determined as one of the symbol indices without separate signaling.
b. As another method, the symbol index E may be indicated as one of the following: 1) a symbol index S+O1 obtained by applying a symbol offset O1 to the symbol index S, 2) a symbol index S+D+O2 obtained by applying a symbol offset O2 to a symbol index S+D, 3) a symbol index D+O3 obtained by applying a symbol offset O3 to a symbol index D, and 4) a symbol index L+O4 obtained by applying a symbol offset O4 to a last symbol index L in the slot. Alternatively, the symbol index E may be determined as one of the symbol indices without separate signaling.
i. In 1-b of Step 3, the symbol offsets O1, O2, O3, and O4 may be set to positive and/or negative integer values including “0”.
ii. For example, the symbol index E may be indicated as one of the following: 1) the symbol index S, 2) the symbol index S+D, 3) the symbol index D, and 4) the symbol index L. Alternatively, the symbol index E may be determined as one of the symbol indices without separate signaling.
