The paging response is transmitted on at least one of the uplink transmission resources allocated for the paging response. A method for wireless communication at a base station includes identifying uplink transmission resources for paging responses, transmitting an indication of the uplink transmission resources allocated for paging responses, transmitting a paging indication to at least one UE, and receiving a paging response from one or more UEs using a receive beam sweep. The paging response is received on an associated beam on at least one of the uplink transmission resources allocated for paging responses. ## Claims ### Claim 1 A method for wireless communication at a user equipment (UE), comprising: receiving a paging indication from a base station during a paging procedure, wherein the paging indication indicates at least one uplink transmission resource allocated for a paging response of the paging procedure;
