Method and apparatus for scheduling information for a downlink data channel

An apparatus comprising:

• a controller that controls operations of the apparatus;
• and
• a transceiver coupled to the controller, where the transceiver
• transmits scheduling information to a user equipment regarding a downlink data channel in a slot, wherein scheduling information includes information regarding at least a set of allocated subcarriers and the downlink data channel requires the user equipment to send an immediate hybrid automatic repeat request acknowledgement feedback within the slot, and
• transmits downlink data by using every x-th subcarrier among the allocated subcarriers in the last symbol of the downlink data channel,
• wherein every x-th subcarrier comprises every subcarrier that skips a number of subcarriers,
• wherein the controller sets a value of x based on user equipment processing capability corresponding to at least the user equipment processing time of downlink data and indicates to the user equipment the value of x, and
• wherein x comprises a positive integer greater than one.

A method comprising:

• receiving scheduling information from a network entity at a user equipment, the scheduling information regarding a downlink data channel in a slot, where the scheduling information includes information regarding at least a set of allocated subcarriers and the downlink data channel requires the user equipment to send an immediate hybrid automatic repeat request acknowledgement feedback within the slot;
• receiving downlink data by using every x-th subcarrier among the allocated subcarriers in the last symbol of the downlink data channel;
• and
• transmitting a hybrid automatic repeat request acknowledgement in response to receiving the downlink data,
• wherein every x-th subcarrier comprises every subcarrier that skips a number of subcarriers, and
• wherein the method further comprises receiving a value of x that is set based on user equipment processing capability corresponding to at least user equipment processing time of downlink data, and
• wherein x comprises a positive integer greater than one.
