Scheduling resources for user equipment (UE) sidelink communication

An apparatus configured for wireless communication, the apparatus comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor, wherein the at least one processor is configured:
• to schedule, by a base station, resources for a sidelink between a first user equipment (UE) and a specified second UE, wherein the first UE is in communication with the base station and is a UE to transmit to the specified second UE via the sidelink;
• and
• to transmit, by the base station, control signaling to the first UE to implement the sidelink between the first UE and the specified second UE in accordance with the scheduling, wherein the control signaling is configured to assign granted resources as link resources for the sidelink between the first UE and the specified second UE and is configured to specify to the first UE the specified second UE is a sidelink receiver UE for the sidelink by including at least one of:
• a hybrid automatic repeat request (HARQ) process identifier providing a sidelink RX UE indicator for the specified second UE;
• or
• a cyclic redundancy check (CRC) of downlink control information (DCI) of the control signaling scrambled using a radio network temporary identifier (RNTI) distributed to the first UE and the specified second UE that provides destination identification for the specified second UE.

A method of wireless communication, comprising:

• receiving, by a first user equipment (UE) from a base station, control signaling scheduling resources for a sidelink between the first UE and a specified second UE, wherein the first UE is in communication with the base station and is a UE to transmit to the specified second UE via the sidelink, and wherein the control signaling is configured to assign granted resources as link resources for the sidelink between the first UE and the specified second UE and is configured to specify to the first UE the specified second UE is a sidelink receiver UE for the sidelink by including at least one of:
• a hybrid automatic repeat request (HARQ) process identifier providing a sidelink RX UE indicator for the specified second UE;
• or
• a cyclic redundancy check (CRC) of downlink control information (DCI) of the control signaling scrambled using a radio network temporary identifier (RNTI) distributed to the first UE and the specified second UE that provides destination identification for the specified second UE;
• and
• implementing, by the first UE based on the control signaling, the sidelink between the first UE and the specified second UE in accordance with the scheduling.
