1. A method of wireless communication by a first user equipment (UE), the method comprising:
receiving, from a base station, information associated with sidelink communication, wherein the information associated with sidelink communication indicates a resource allocation associated with sidelink communication;
when a sidelink communication pattern is configured in a centralized manner,
sending, to the base station, a request associated with communicating with a second UE on a first sidelink channel, wherein the centralized manner comprises the base station assisting sidelink communication between UEs by determining the sidelink communication pattern, wherein the sidelink communication pattern indicates a slot in which the second UE is a transmitter or a receiver for the sidelink communication, and
receiving, from the base station, the sidelink communication pattern associated with the second UE;
when the sidelink communication pattern is configured in a distributed manner and that the first UE is a transmitting UE,
sending, to the second UE based on the resource allocation, a first request associated with the sidelink communication pattern associated with the second UE based on a first schedule associated with the first UE; and
receiving, from the second UE, one of a confirmation of the first request associated with the sidelink communication pattern associated with the second UE or a second request associated with the sidelink communication pattern associated with the second UE, wherein the sidelink communication pattern associated with the second UE is determined based on the first request or the second request, wherein the distributed manner comprises the base station refraining from scheduling any UEs on the resource allocation associated with the sidelink communication;
when the sidelink communication pattern is configured in the distributed manner and that the first UE is a receiving UE,
receiving, from the second UE based on the resource allocation, a first request associated with the sidelink communication pattern associated with the second UE;
determining, based on a first schedule associated with the first UE, whether to confirm the first request associated with the sidelink communication pattern associated with the second UE; and
sending, to the second UE, a confirmation of the first request associated with the sidelink communication pattern associated with the second UE when the first request is determined to be confirmed or a second request associated with the sidelink communication pattern, wherein the sidelink communication pattern associated with the second UE is determined based on the first request or the second request;
determining, based on the information associated with sidelink communication, the sidelink communication pattern associated with the second UE; and
communicating with the second UE on the first sidelink channel using at least one beam that is determined based on the sidelink communication pattern associated with the second UE.
