Title: METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING PHYSICAL BROADCAST CHANNEL
Abstract:
Provided in the present application are a method and device for transmitting and receiving a physical broadcast channel, for use in solving the problem in the prior art in which a terminal device cannot acquire accurate broadcast channel information and, as a result, cannot access a network. In the method, when two broadcast channel signals in corresponding two physical broadcast channels are received on two time-frequency resource positions by a terminal device, same determines that information in two pieces of broadcast information carried in the two broadcast channel signals other than offsets of the corresponding time-frequency resource positions are identical, acquires the time offset difference of the two time-frequency resource positions, and generates a scrambling sequence on the basis of the time offset difference; and the terminal device descrambles respectively the two broadcast channel signals on the basis of the scrambling sequence and a preset scrambling sequence, thus implementing joint decoding of the two broadcast channel signals to acquire either piece of broadcast information. As such, the terminal device is allowed to access a network on the basis of various information in the broadcast information.
