The unpaid income of each period is carried forward to the fund share on the maturity date (postponed in case of holidays). You sell it all on the opening day of the maturity date, and the unpaid proceeds will be transferred to the relevant bank account. If you don't sell or partially sell on the first day of the maturity date, the remaining shares and unpaid income will automatically roll into the next period. The sold part and the corresponding unpaid income will be transferred to the associated bank account together. Whether this unpaid income is transferred to the account in proportion to the number of sales shares or left in the account to be rolled into the next period depends on the product rules stipulated by the fund company.
