Transmission parameter modification for uplink communications

A method of wireless communication performed by a base station, comprising:

• transmitting a configuration associated with modifying one or more transmission parameters, other than a transmit power, for uplink communications;
• transmitting downlink control information that indicates a transmission parameter value, for a transmission parameter of the one or more transmission parameters, for an uplink communication;
• receiving the uplink communication, wherein the uplink communication is transmitted using a modified transmission parameter value that is different from the transmission parameter value indicated in the downlink control information, a required transmit power for the uplink communication being determined based at least in part on a measured pathloss parameter, the required transmit power being greater than a maximum transmit power, the modified transmission parameter value being modified based at least in part on the configuration based at least in part on the required transmit power being greater than the maximum transmit power, a transmission parameter corresponding to the modified transmission parameter value including at least one of a modulation and coding scheme, a transport block size, or a resource allocation;
• and
• decoding the uplink communication.

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

• a memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
• receive a configuration for uplink communications;
• determine a required transmit power for an uplink communication, wherein the required transmit power is determined based at least in part on a pathloss parameter measured by the UE;
• modify at least one transmission parameter for the uplink communication based at least in part on the configuration if the required transmit power is greater than a maximum transmit power, wherein the at least one transmission parameter includes at least one of a modulation and coding scheme, a transport block size, or a resource allocation;
• and
• transmit the uplink communication using the modified at least one transmission parameter.

An apparatus for wireless communication, comprising:

• means for receiving a configuration for uplink communications;
• means for determining a required transmit power for an uplink communication, wherein the required transmit power is determined based at least in part on a pathloss parameter measured by the apparatus;
• means for modifying at least one transmission parameter for the uplink communication based at least in part on the configuration if the required transmit power is greater than a maximum transmit power, wherein the at least one transmission parameter includes at least one of a modulation and coding scheme, a transport block size, or a resource allocation;
• and
• means for transmitting the uplink communication using the modified at least one transmission parameter.
