Information sending and receiving method and related device
First Claim
1. An information sending method, wherein the method comprises:
- enabling, by a network device, a physical broadcast channel (PBCH) to carry Q bits that are used to indicate a synchronization signal (SS) block time index, the SS block time index comprising M bits, (M−
Q) bits of the M bits being implicitly carried by using demodulation reference signal (DMRS) sequences of the PBCH, M being a first integer greater than 0, and Q being a second integer greater than 0; and
sending the PBCH to a terminal device.

Abstract
Embodiments of this application disclose an information sending and receiving method and a related device. The method may include: sending, by a network device, first indication information to a terminal device, where the first indication information is carried by using m bits in a downlink signal, and the first indication information includes related information indicating a quantity n of synchronization signal blocks SS blocks included in a synchronization signal burst set SS burst set, where m<log2N, N is a maximum value of a quantity of SS blocks supported in the SS burst set, both m and n are integers greater than 1, and n is less than or equal to N. According to the embodiments of this application, a prior-art problem that transmission overheads are relatively high when the network device indicates the quantity n of SS blocks to the terminal device can be resolved.
