A transmission method of physical broadcasting channel aerial information

Abstract

The invention discloses a method for transmitting the antenna information of a physical broadcast channel and is applied in a wireless communication system, and according to the transmission antenna number of the physical broadcast channel and which time the current sending belongs to in a period, a sending end selects a corresponding scrambling sequence for implementing the scrambling of original information bits, generates a cyclical redundancy check (CRC) code, and sends out the CRC code together with the data; wherein, two antennas and four antennas are corresponding to different scrambling sequences. The method of the invention can well detect the antenna information of the physical broadcast channel and is characterized in that the two situations with two antennas and four antennas are well differentiated, thus ensuring the decoding performance of other physical channels.

Description

technical field

[0001] The invention relates to the field of mobile communication, in particular to a method for transmitting antenna information of a physical broadcast channel. Background technique

[0002] like figure 1 As shown, it is a schematic diagram of an LTE (Long Term Evolution) system frame structure. In the LTE system, a 10ms radio frame is divided into two half frames, each half frame is divided into 10 time slots with a length of 0.5ms, and two time slots form a subframe with a length of 1ms, and a half frame contains 5 subframes. frame.

[0003] like figure 2 As shown, it is a schematic diagram of sending a physical broadcast channel in an LTE system. The sending period of the physical broadcast channel is 40ms, wherein the physical broadcast channel is sent every 10ms, and within a period, the physical broadcast channel sends the same information each time. In order to achieve accurate timing in a cycle, the LTE standard stipulates that by using differ...
