Mixed format techniques for orphaned symbols in uplink channel repetitions

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

• receiving, from a base station, an indication of a configuration for symbol repetition, the configuration comprising one or more parameters for transmitting a message on a physical uplink channel;
• selecting a second format based at least in part on a number of resource blocks supported by a first format indicated by the indication of the configuration;
• formatting, based at least in part on the first format indicated by the indication of the configuration, a first portion of a set of repetitions of the message scheduled for transmission before a slot boundary, and based at least in part on a and indicated by the indication of the configuration, a second portion of the set of repetitions of the message scheduled for transmission after the slot boundary, wherein the second portion of the set of repetitions is a single symbol, wherein formatting the second portion of the set of repetitions is based at least in part on selecting the second format;
• and
• transmitting, to the base station, the first portion of the set of repetitions formatted according to the first format and the second portion of the set of repetitions according to the second format.

A method for wireless communication by a base station, comprising:

• transmitting, to a user equipment (UE), an indication of a configuration for symbol repetition, the configuration comprising one or more parameters for transmitting a message on a physical uplink channel;
• indicating, via the indication of the configuration, a selection of a second format for the UE to use based at least in part on a number of bits supported by a first format indicated by the indication of the configuration;
• receiving, from the UE, a first portion of a set of repetitions of the message transmitted before a slot boundary and formatted according to the first format indicated by the indication of the configuration, and a second portion of the set of repetitions of the message transmitted after the slot boundary and formatted according to a second format indicated by the indication of the configuration, the second portion of the set of repetitions being a single symbol, and wherein the second portion of the set of repetitions is formatted based at least in part on selecting the second format;
• and
• processing the first portion of the set of repetitions of the message according to the first format and the second portion of the set of repetitions of the message according to the second format.

An apparatus for wireless communication by a user equipment (UE), comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, from a base station, an indication of a configuration for symbol repetition, the configuration comprising one or more parameters for transmitting a message on a physical uplink channel;
• select a second format based at least in part on a number of bits supported by a first format indicated by the indication of the configuration;
• format, based at least in part on the first format indicated by the indication of the configuration, a first portion of a set of repetitions of the message scheduled for transmission before a slot boundary, and based at least in part on a second format indicated by the indication of the configuration, a second portion of the set of repetitions of the message scheduled for transmission after the slot boundary, wherein the second portion of the set of repetitions is a single symbol, and wherein formatting the second portion of the set of repetitions is based at least in part on selecting the second format;
