Techniques for communicating feedback in low latency wireless communications

A method for communicating uplink control information (UCI), comprising:

• transmitting one or more resource assignments for a user equipment to transmit over a first symbol and at least one second symbol that comprise a first transmission time interval (TTI), wherein at least one resource assignment of the one or more resource assignments includes, at least for the at least one second symbol, an indication of one or more consecutive frequency resources divided in a bandwidth of an uplink channel based on a factor;
• and
• receiving, in the first TTI and according to the one or more resource assignments, a reference signal over the first symbol;
• and
• receiving, in the first TTI, according to the one or more resource assignments, and only in multiple frequency resources that are interleaved in frequency based on the factor, a data signal indicating UCI over the at least one second symbol.

An apparatus for wireless communications, comprising:

• a transceiver for communicating one or more wireless signals via one or more antennas;
• a memory configured to store instructions;
• and
• one or more processors communicatively coupled with the transceiver and the memory, wherein the one or more processors are configured to:
• receive one or more resource assignments from an access point to transmit over a first symbol and at least one second symbol that comprise a first transmission time interval (TTI), wherein a resource assignment of the one or more resource assignments includes, at least for the at least one second symbol, an indication of one or more consecutive frequency resources divided in a bandwidth of an uplink channel based on a factor;
• and
• transmit, in the first TTI and according to the one or more resource assignments, a reference signal over the first symbol;
• and
• transmit, in the first TTI, according to the one or more resource assignments, and only in multiple frequency resources that are interleaved in frequency based on the factor, a data signal indicating UCI over the at least one second symbol.
