Physical uplink shared channel coverage enhancements

A method for wireless communication, comprising:

• transmitting an uplink grant that conveys an indication of a multi-transmission opportunity (TxOP) grant and a transport block scaling factor;
• receiving, during a first TxOP, a first uplink transmission in one or more subframes in accordance with the multi-TxOP grant and the transport block scaling factor, wherein the first uplink transmission comprises a dense reference signal based at least in part on a medium captured for one or more repetitions of uplink data in the first uplink transmission in the first TxOP, and wherein the dense reference signal identifies the beginning of a first repetition of the uplink data in the uplink transmission during the first TxOP;
• receiving, during a second TxOP different from the first TxOP, a second uplink transmission in one or more subframes in accordance with the multi-TxOP grant and the transport block scaling factor;
• and
• transmitting a trigger indicator in the second TxOP during a subframe that is before the subframe in which the first or second uplink transmissions are transmitted, the trigger indicator indicating that repetitions of the uplink data are permitted to be transmitted during the second TxOP.

An apparatus for wireless communication, in a system comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
• receive an uplink grant that conveys an indication of a multi-transmission opportunity (TxOP) grant and a transport block scaling factor;
• transmit, during a first TxOP, a first uplink transmission in one or more subframes in accordance with the multi-TxOP grant and the transport block scaling factor, wherein the first uplink transmission comprises a dense reference signal based at least in part on capturing a medium for one or more repetitions of uplink data in the first uplink transmission in the first TxOP, and wherein the dense reference signal identifies the beginning of a first repetition of the uplink data in the uplink transmission during the first TxOP;
• transmit, during a second TxOP different from the first TxOP, a second uplink transmission in one or more subframes in accordance with the multi-TxOP grant and the transport block scaling factor;
• and
• receive a trigger indicator in the second TxOP during a subframe that is before the subframe in which the first or second uplink transmissions are transmitted, the trigger indicator indicating that repetitions of the uplink data are permitted to be transmitted during the second TxOP.
