12. The method of claim 6 , wherein transmitting, by the device, the first acknowledgement message further comprises transmitting, by the device, the first acknowledgement message over the wireless communication network in a time slot k that is prior to an end of the time slots n to n+(N rep −1).

13. A method for enhanced Multiple Transmit and Receive Point (M-TRP) Physical Uplink Control Channel (PUCCH) transmission in a wireless communication network, the method comprising:

receiving, at a device, M occasions of a Physical Downlink Shared Channel (PDSCH) in a single Downlink Control Information (DCI) M-TRP scheme having a slot-based repetition in N time slots in which N is an integer greater than 1, in which the PDSCH is associated with two TCI states, and in which M≤N; and

determining, at the device, TCI states of the M occasions based on a dynamic grant single-DCI M-TRP PDSCH with slot-based repetition.

wherein determining, at the device, TCI states further comprises determining, at the device, N valid time slots each having valid symbols.

17. The method of claim 16 , wherein the N occasions end after a predetermined deferral time T deferral max from an end of a last symbol of an occasion in time slot N.

18. The method of claim 13 , further comprising transmitting, by the device, an acknowledgement message over the wireless communication network for the PDSCH based on a predetermined number of time slots from a last received PDSCH occasion.

19. A method for enhanced Physical Uplink Control Channel (PUCCH) transmission in a wireless communication network, the method comprising:

determining, at a device, a Physical Uplink Control Channel (PUCCH) over the wireless communication network with acknowledgement information for a Semi-Persistently Scheduled (SPS) Physical Download Shared Channel (PDSCH) or a first dynamic grant PDSCH scheduled by a first Physical Download Control Channel (PDCCH) and a first PUCCH resource with HARQ-ACK information on a first PUCCH cell with SCS numerology of μ 1 ;
