Method and apparatus for determining uplink transmission in mobile communications

A method, comprising:

• receiving, by a processor of an apparatus, a downlink (DL) information, wherein the DL information is associated with an uplink (UL) transmission;
• and
• transmitting, by the processor, the UL transmission, wherein
• in an event that a time span between the DL information and an earliest scheduled UL transmission of a group of time domain overlapped UL transmissions is scheduled to be greater than or equal to a specific time span, a timing of determining the UL transmission of the group of time domain overlapped UL transmissions is before the specific time span ahead of the earliest scheduled UL transmission;
• or
• in an event that a time span between the DL information and the UL transmission is scheduled to be less than the specific time span, the UL transmission is scheduled without collision,
• wherein the specific time span is configured to be greater than a required time span between the DL information and the earliest scheduled UL transmission.

An apparatus, comprising:

• a transceiver which, during operation, wirelessly communicates with a wireless network;
• and
• a processor communicatively coupled to the transceiver such that, during operation, the processor performs operations comprising:
• transmitting, by the transceiver, a downlink (DL) information, wherein the DL information is associated with an uplink (UL) information;
• and
• receiving, via the transceiver, the UL transmission, wherein
• in an event that a time span between the DL information and an earliest scheduled UL transmission of a group of time domain overlapped UL transmissions is scheduled to be greater than or equal to a specific time span, a timing of determining the UL transmission of the group of time domain overlapped UL transmissions is before the specific time span ahead of the earliest scheduled UL transmission;
• or
• in an event that a time span between the DL information and the UL transmission is scheduled to be less than the specific time span, the UL transmission is scheduled without collision,
• wherein the specific time span is configured to be greater than a required time span between the DL information and the earliest scheduled UL transmission.
