1. A method for wireless communication, comprising:
transmitting, by a base station, a first control message that includes a first scheduling information of a first data transmission on a first serving cell to a user device, wherein the first control message comprises a first set of New Data Indicator (NDI) values corresponding to a first set of Transport Blocks (TBs) of the first data transmission;
processing, by the base station, the first data transmission for the user device on the first serving cell according to the first scheduling information;
transmitting, by the base station to the user device, a second control message that includes a second scheduling information of a second data transmission on a second cell that is different from the first serving cell,
wherein the second control message comprises a second set of NDI values corresponding to a second set of TBs of the second data transmission,
wherein the second control message indicates that a TB of the second data transmission is a retransmission of a corresponding TB of the first data transmission upon an NDI value of the TB in the second control message being a same as a prior NDI value of the corresponding TB in the first control message,
wherein the first data transmission is a prior transmission corresponding to the second data transmission, and
wherein the second control message comprises a first identifier for the first serving cell and a first Hybrid Automatic Repeat Request (HARQ) process number for the first data transmission, the second control message further comprising a second identifier for the second cell and a second HARQ process number for the second data transmission; and
processing, by the base station, the second data transmission for the user device on the second cell according to the second scheduling information.
