摘要： Embodiments of the present invention disclose a method and an apparatus for indicating a transmission time interval. The implementation solutions of the method includes: receiving an access preamble from a user equipment UE, where the access preamble carries a signature; determining whether a cell where the UE is located is configured with an extended acquisition indicator EAI, and sending, on an acquisition indicator channel AICH of an access timeslot corresponding to an access timeslot where the access preamble is received, an acquisition indicator AI corresponding to the signature of the access preamble. Therefore, the problem that the judging condition of EAI configured is always YES is solved; the UE access delay may be reduced; the number of preambles sent by the UE may be reduced; and interference on the uplink may be reduced.

摘要： This application provides a PBCH transmission method and an apparatus. The method includes: receiving, by a terminal device, a PBCH sent by a network device, where the PBCH includes seven most significant bits of an SFN of a radio frame in which the PBCH is located; determining, by the terminal device, a least significant bit of the PBCH based on indication information of the least significant bit of the SFN; determining, by the terminal device based on the PBCH, at least one of a scrambling code, a CRC check mask, or a redundancy version of the PBCH, and determining two remaining bits of the SFN based on a one-to-one correspondence between the two remaining bits of the SFN and the at least one of the scrambling code, the CRC check mask, or the redundancy version of the PBCH; and determining, by the terminal device based on the least significant bit, the seven most significant bits, the second least significant bit, and the third least significant bit of the SFN, the SFN of the radio frame in which the PBCH is located. This reduces complexity of blind detection. In addition, the method can be applicable to scenarios with different quantities of PBCHs sent within one PBCH TTI. An application scope is relatively wide.
