Semi-persistent scheduling configurations for sidelink communications

An apparatus for wireless communications at a first user equipment (UE), comprising:

• one or more processors;
• memory coupled with the one or more processors;
• and
• instructions stored in the memory and executable by the one or more processors to cause the apparatus to:
• receive, from a network entity, a configured grant pair configuration indicating:
• a sidelink semi-persistent scheduling resource allocation for a sidelink channel for communicating with a second UE, and
• a first configured grant for the first UE and a second configured grant for the second UE, wherein the first configured grant and the second configured grant, of a configured grant pair, each indicate:
• an activation of the sidelink semi-persistent scheduling resource allocation for communications between the first UE and the second UE via the sidelink channel,
• which of the first UE or the second UE is a transmitter for communications between the first UE and the second UE on the sidelink channel, and
• which of the first UE or the second UE is a receiver for communications between the first UE and the second UE on the sidelink channel;
• receive, from the network entity, the first configured grant of the configured grant pair based at least in part on the configured grant pair configuration;
• and
• communicate with the second UE on the sidelink channel according to the sidelink semi-persistent scheduling resource allocation based at least in part on the first configured grant.

An apparatus for wireless communications at a first user equipment (UE), comprising:

• which of the first UE or the second UE is a transmitter for communication between the first UE and the second UE on the sidelink channel, and
• which of the first UE or the second UE is a receiver for communication between the first UE and the second UE on the sidelink channel;
• means for receiving, from the network entity, the first configured grant of the configured grant pair based at least in part on the configured grant pair configuration;
• and
• means for communicating with the second UE on the sidelink channel according to the sidelink semi-persistent scheduling resource allocation based at least in part on the first configured grant.

A non-transitory computer-readable medium storing code for wireless communications at a first user equipment (UE), the code comprising instructions executable by one or more processors to:

• receive, from a network entity, a configured grant pair configuration indicating:
• a sidelink semi-persistent scheduling resource allocation for a sidelink channel for communicating with a second UE, and
• a first configured grant for the first UE and a second configured grant for the second UE, wherein the first configured grant and the second configured grant, of a configured grant pair, each indicate:
• an activation of the sidelink semi-persistent scheduling resource allocation for communication between the first UE and the second UE via the sidelink channel,
• which of the first UE or the second UE is a transmitter for communication between the first UE and the second UE on the sidelink channel, and
• which of the first UE or the second UE is a receiver for communication between the first UE and the second UE on the sidelink channel;
• receive, from the network entity, the first configured grant of the configured grant pair based at least in part on the configured grant pair configuration;
• and
• communicate with the second UE on the sidelink channel according to the sidelink semi-persistent scheduling resource allocation based at least in part on the first configured grant.
