This is what is supposed to happen, from the General Instruction of the Roman Missal: (What I am getting is in boldface)
The rites preceding the Liturgy of the Word, namely the Entrance, Greeting, Act of Penitence, Kyrie, Gloria, and Collect, have the character of a beginning, introduction, and preparation.
After the people have gathered, the Entrance chant begins as the priest enters with the deacon and ministers.
The singing at this time is done either alternately by the choir and the people or in a similar way by the cantor and the people, or entirely by the people, or by the choir alone…If there is no singing at the entrance, the antiphon in the Missal is recited either by the faithful, or by some of them, or by a lector; otherwise, it is recited by the priest himself, who may even adapt it as an introductory explanation.
(No entrance chant, singing, or entrance antiphon, just instrumental music.)
- When they reach the sanctuary, the priest, the deacon, and the ministers reverence the altar with a profound bow.
As an expression of veneration, moreover, the priest and deacon then kiss the altar itself…
(Moved to after the Kyrie)

(Priest has never entered sanctuary, he kneels on the first step, all of congregation kneels. Sign of Cross moved to after Kyrie.)
(Greeting: “The Lord be with you. And also with you”…omitted.)
- Then the priest invites those present to take part in the Act of Penitence, which, after a brief pause for silence, the entire community carries out through a formula of general confession. The rite concludes with the priest’s absolution…
(Act of Penitence omitted. Priest’s absolution moved to after Kyrie)
- After the Act of Penitence, the Kyrie is always begun, unless it has already been included as part of the Act of Penitence.
**At the end of the Kyrie, the priest makes the sign of the cross and pronounces the priest’s absolution. All still kneeling. There is no greeting.
The priest rises, enters the Sanctuary, and reverences the Altar, goes to the chair and prays the Collect.) **
The Gloria (omitted on Sundays in Lent)
Next the priest invites the people to pray. All, together with the priest, observe a brief silence so that they may be conscious of the fact that they are in God’s presence and may formulate their petitions mentally. Then the priest says the prayer which is customarily known as the Collect…
