Support for an increased quantity of sidelink configured grants

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

• receiving, in radio resource control (RRC) signaling, scheduling information corresponding to a first quantity of sidelink configured grants, the first quantity of sidelink configured grants being greater than eight sidelink configured grants;
• receiving, in downlink control information (DCI), an activation of a sidelink configured grant of the first quantity of sidelink configured grants, wherein the activation is indicated based on at least one of:
• a configuration index having a number of bits indicated by an RRC signaled parameter that indicates a quantity of bits of the configuration index in the DCI for the activation of sidelink configured grants, wherein the configuration index indicates the activation of the sidelink configured grant from the first quantity of sidelink configured grants,
• a first combination of a configuration index codepoint of the DCI and a second codepoint of the DCI, wherein the first combination indicates the activation of the sidelink configured grant from the first quantity of sidelink configured grants, or
• a second combination of the configuration index codepoint of the DCI and a cyclic redundancy check (CRC) scrambling sequence for the DCI, wherein the second combination indicates the activation of the sidelink configured grant from the first quantity of sidelink configured grants;
• and
• transmitting sidelink traffic to a second UE based on the sidelink configured grant.

An apparatus for wireless communication at a base station, comprising:

• one or more memories;
• and
• one or more processors coupled to the one or more memories and configured to cause the base station to:
• transmit, in radio resource control (RRC) signaling, scheduling information corresponding to a first quantity of sidelink configured grants, the first quantity of sidelink configured grants being greater than eight sidelink configured grants;
• and
• transmit, in downlink control signaling (DCI) for a user equipment (UE), an activation of a sidelink configured grant of the first quantity of sidelink configured grants, wherein the activation is indicated based on at least one of:
• a configuration index having a number of bits indicated by an RRC signaled parameter that indicates a quantity of bits of the configuration index in the DCI for the activation of sidelink configured grants, wherein the configuration index indicates the activation of the sidelink configured grant from the first quantity of sidelink configured grants,
• a first combination of a configuration index codepoint of the DCI and a second codepoint of the DCI, wherein the first combination indicates the activation of the sidelink configured grant from the first quantity of sidelink configured grants, or
• a second combination of the configuration index codepoint of the DCI and a cyclic redundancy check (CRC) scrambling sequence for the DCI, wherein the second combination indicates the activation of the sidelink configured grant from the first quantity of sidelink configured grants.
