Abstract
Embodiments of this application provide a random access response method and an apparatus. The method includes: RARs associated with one RO are transmitted based on groups, so that a transport block size of RAR data transmitted each time is reduced, and N bits in DCI format 1_0 of CRC are scrambled by using a RA-RNTI to indicate scheduling information of N RAR groups in a PDSCH. Alternatively, DCI format 1_0 of CRC is scrambled by using identifiers of RAR groups, to correspondingly schedule the RAR groups in the PDSCH. According to this application, a problem of a large transport block caused by a large quantity of RARs being transmitted in a PDSCH can be avoided, so that a modulation order or a bit rate is reduced, and demodulation performance of a terminal device is improved.
