Methods for beam determination after beam pair link indication

A method for wireless communication, comprising:

• establishing, at a base station, a first connection with a user equipment (UE) using a first beam pair link (BPL);
• maintaining a BPL for data, which is initialized with the first BPL and is used during data transmission time intervals (TTIs);
• changing the BPL for data to a second BPL based at least on one or more channel conditions;
• identifying a threshold value corresponding to an amount of time for the UE to decode an indication of a BPL switch and apply a different BPL based at least in part on the indication;
• allocating resources for the UE for a first data TTI;
• determining a scheduling offset between a control information transmission indicating the allocated resources and a start of the first data TTI;
• and
• transmitting control information to the UE, the control information including the scheduling offset, an assignment for the first data TTI, and a BPL indication, and wherein the scheduling offset, a time of the control information transmission, the threshold value, and the BPL indication indicate to the UE whether the BPL for data will change and a BPL change time.
