Methods, systems, and devices for wireless communication are described. A wireless device may determine that a serving base station supports multi-code and single-code transmissions, receiving a scheduling message having a cyclic redundancy check scrambled with a radio network temporary identifier (RNTI), determine resources for communicating with the serving base station based on the scheduling message, and communicate on the resources using coding associated with the single-code transmissions. A base station may identify at least one user equipment that supports single-code transmissions, transmit a scheduling message having a cyclic redundancy check (CRC) scrambled with a radio network temporary identifier (RNTI), wherein the scheduling message schedules the at least one user equipment for communication on resources using coding associated with the single-code transmissions and communicate with the at least one user equipment on the resources using the coding.
