Channel reservation techniques for unlicensed spectrum

A method of wireless communication at a user equipment (UE) comprising:

• receiving, in an unlicensed radio frequency (RF) spectrum band, a channel reservation transmission indicating a transmission opportunity and an allocation of downlink (DL) transmissions and uplink (UL) transmissions, wherein the channel reservation transmission comprises a channel state information (CSI) request;
• determining CSI associated with the transmission opportunity;
• and
• transmitting a CSI report in a channel reservation response transmission, wherein the channel reservation response transmission comprises an interference threshold indicator associated with the UE that indicates an amount of interference tolerable by the UE.

An apparatus for wireless communication, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory, the instructions being executable by the processor to:
• identify a transmission opportunity duration for a transmission;
• determine an allocation between downlink (DL) transmissions and uplink (UL) transmissions for the identified transmission opportunity duration;
• broadcast, in an unlicensed radio frequency (RF) spectrum band, a channel reservation transmission indicating the identified transmission opportunity duration and the determined allocation, wherein the channel reservation transmission comprises a channel state information (CSI) request;
• and
• receive a channel reservation response transmission comprising an interference threshold indicator associated with a user equipment (UE) that indicates an amount of interference tolerable by the UE.
