Flexible resource reservation indication in sidelink

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

• receiving, from a first UE, a single control information transmission indicating control information, wherein the control information includes an indication of one or more first resource reservations and one or more second resource reservations, wherein the one or more second resource reservations have a different frequency resource allocation than the one or more first resource reservations, and wherein a size of the control information is based on a configuration indicating whether the control information includes resource reservations with different frequency resource allocations, wherein the configuration further indicates that a threshold number of resource reservations in the control information determines whether the control information includes the one or more second resource reservations with the different frequency resource allocation;
• determining time and frequency resource allocations for communicating with the first UE based on the indication of the one or more first resource reservations and the one or more second resource reservations;
• and
• communicating with the first UE based on the determination of the time and frequency resource allocations.

An apparatus for wireless communication, comprising:

• a memory;
• a processor coupled to the memory, the processor and the memory being configured to:
• determine, for sidelink communications with a user equipment (UE), one or more first resource reservations and one or more second resource reservations, wherein the one or more second resource reservations have a different frequency resource allocation than the one or more first resource reservations;
• and
• obtain a configuration indicating whether control information includes resource reservations with different frequency resource allocations, wherein a size of the control information is based on the configuration, wherein the configuration indicates that a threshold number of resource reservations in the control information determines whether the control information includes the one or more second resource reservations with the different frequency resource allocation;
• and
• a transceiver configured to:
• transmit, to the UE, a single control information transmission indicating the control information, wherein the control information includes an indication of the one or more first resource reservations and the one or more second resource reservations;
• and
• communicate with the UE based on the one or more first resource reservations and the one or more second resource reservations.
