1. A method of wireless communication at a base station, comprising:
allocating a set of resources for transmission by a user equipment (UE);
transmitting, to another base station in association with handover of the UE, an indication that a capacity of the set of resources is insufficient for an amount of data indicated by a buffer status report (BSR) from the UE; and
calculating a remaining amount in at least one subgroup of the data for each of a set of logical channels (LCHs) in at least one logical channel group (LCG) associated with the at least one subgroup of the data, wherein the calculating the remaining amount in the at least one subgroup of the data for each of the set of logical channels (LCHs) in the at least one LCG is performed using a mapping between the at least one LCG and the set of LCHs for the another base station,
wherein the indication indicates one remaining amount in the at least one subgroup of the data for each of the set of LCHs in the at least one LCG, and
wherein the another base station schedules the UE to uplink the remaining amount in the at least one subgroup of the data before the another base station receives a BSR from the UE.
