Interference management for two-step random access

A method for wireless communication at a base station serving a cell, comprising:

• receiving, from a user equipment (UE) served by the cell, a first random access message of a two-step random access channel procedure, wherein information bits of a random access payload associated with the first random access message are scrambled based at least in part on a random access radio network temporary identifier, and wherein a scrambling sequence applied to the information bits of the random access payload is a function of a cell identifier and a UE identifier;
• transmitting, to the UE, a second random access response message of the two-step random access channel procedure in response to the first random access message, the second random access response message being transmitted based at least in part on one or more cell-specific transmission parameters or cell-specific transmission schemes;
• and
• establishing a connection with the UE based at least in part on the first random access message and the second random access response message.

A user equipment (UE) for wireless communication in a cell, comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and operable to execute the code to cause the UE to:
• transmit, to a base station serving the cell, a first random access message of a two-step random access procedure, the first random access message including a random access preamble and a random access payload, at least one of the random access preamble or the random access payload being transmitted based at least in part on one or more cell-specific transmission parameters or cell-specific transmission schemes, wherein information bits of the random access payload are scrambled based at least in part on a random access radio network temporary identifier, and wherein a scrambling sequence applied to the information bits of the random access payload is a function of a cell identifier and a UE identifier;
• receive, from the base station, a second random access response message of the two-step random access procedure in response to the first random access message;
• and
• establish a connection with the base station based at least in part on the first random access message and the second random access response message.
