In some aspects, a user equipment (UE) may obtain an indication that a network node is configured to accept a request for the network node to perform network coding for a communication from the UE. The UE may transmit, based at least in part on the UE being within an area associated with the network node, the request for the network node to perform the network coding for the communication. Numerous other aspects are described. ## Claims ### Claim 1 A method of wireless communication performed by a user equipment (UE), comprising: obtaining an indication that a network node is configured to accept a request for the network node to perform network coding for a communication from the UE, wherein a network coded communication comprises two or more communications that are combined using encoding;

and performing retransmissions of one or more communications based at least in part on the UE being outside of the coverage area associated with the network node. ### Claim 11 (depends on 10) The method of claim 10, wherein the performing of the retransmissions of the one or more communications is enabled or disabled based at least in part on a configuration of the UE or an indication received from the network node. ### Claim 12 (depends on 10) The method of claim 10, wherein a maximum number of retransmissions of the one or more communications is based at least in part on a configuration of the UE or an indication received from the network node. ### Claim 13 (depends on 12) The method of claim 12, further comprising refraining from retransmitting the one or more communications based at least in part on determining that the maximum number of retransmissions by the UE has been performed. ### Claim 14 A method of wireless communication performed by a network node, comprising: receiving, from a user equipment (UE), a request for the network node to perform network coding for a communication from the UE, the network coding comprising encoding the communication and another communication to combine the communication and the other communication; and transmitting, to the UE, based at least in part on the UE being within a coverage area associated with the network node, an indication that the network node will perform the network coding for the communication. ### Claim 15 (depends on 14) The method of claim 14, further comprising performing the network coding for the communication based at least in part on the UE being within the coverage area associated with the network node. ### Claim 16 (depends on 14) The method of claim 14, further comprising determining whether to accept the request to perform the network coding for the communication based at least in part on at least one of a location of the network node, a location of the UE, a priority of the communication, a current load of a network associated with the network node, or a current load of the network node. ### Claim 17 (depends on 14) The method of claim 14, further comprising determining that the UE is within the coverage area associated with the network node prior to transmitting the indication that the network node will perform the network coding for the communication. ### Claim 18 (depends on 14) The method of claim 14, further comprising: determining that the UE has moved outside of the coverage area associated with the network node;
