1. A method of wireless communication, comprising:
receiving, at a user equipment (UE), a transmission power configuration for side-link channel transmissions, wherein the transmission power configuration includes a power step-up indication determined in accordance with current transmission conditions wherein the UE is connected to a connected UE via a side-link channel, wherein the connected UE is associated with a connected state with respect to a base station, and wherein the UE is associated with an unconnected or idle state with respect to the base station;
receiving, at the UE, side-link transmissions from the connected UE via the side-link channel; and
transmitting, by the UE, an acknowledgement status of the side-link transmissions to the connected UE via the side-link channel at a first transmission power stepped up according to the power step-up indication, wherein the first transmission power is stepped up according to the power step-up indication in accordance with power step-up criteria being satisfied, the power step-up criteria including:
the acknowledgement status indicating a negative acknowledgement (NACK) of the side-link transmissions; and
the side-link transmissions being associated with a first transmission type,
wherein the first transmission type is associated with eligibility for a retransmission procedure, wherein a second transmission type different than the first transmission type is associated with ineligibility for the retransmission procedure, and wherein the second transmission type is associated with a second transmission power that is less than the first transmission power stepped up according to the power step-up indication.
