17. A method for wireless communication at a user equipment (UE), comprising:
generating, using an initial seed and a pseudo-random shift value, a scrambling sequence, wherein the pseudo-random shift value is a function of one or more of a cell identifier associated with a network node, a radio network temporary identifier (RNTI) of the UE, a frame index of a frame associated with a wireless communication channel, a subframe index of a subframe associated with the wireless communication channel, or a slot index of a slot associated with the wireless communication channel;
scrambling, using the scrambling sequence, one or more codewords as part of generating a baseband signal for the wireless communication channel; and
transmitting the baseband signal to the network node.
