[0023] at the sending end,

[0024] According to the number of transmitting antennas of the physical broadcast channel, the original information bits are sorted according to different sorting methods, CRC bits are generated according to the sorting results, and sent together with the original information bits. The above arrangement is only for generating CRC bits, and the sequence of original information bits remains unchanged when sending.

[0025] First, number the original information bits sequentially. It is stipulated that when the physical broadcast channel is one antenna, the original information bits are sorted from small to large; when the physical broadcast channel has two antennas, the original information bits are sorted from large to small. When the physical broadcast channel has four antennas, the original information bits are sorted in the order of odd numbers and then even numbers; then, CRC bits are generated according to the sorted original information bits. ...

[0030] at the sending end,

[0031] According to the number of transmitting antennas of the physical broadcast channel, the original information bits are sorted according to different sorting methods, CRC bits are generated according to the sorting results, and sent together with the original information bits.

[0032] First, number the original information bits sequentially. It is stipulated that when the physical broadcast channel has one or two antennas, the original information bits are sorted from small to large; to the smallest order; then, generate CRC bits according to the sorted original information bits.

[0033] at the receiving end,

[0034] Decoding is performed in a corresponding manner according to the number of transmitting antennas of different physical broadcast channels in turn. After each decoding, the decoded information bits are sorted according to the sorting method adopted by the sending end under the number of transmitting antennas, and the CRC genera...

Abstract

The invention discloses a method for transmitting the antenna information of a physical broadcast channel, and a sending end arranges the original information bits in sequence according to the number of the sending antennas of the physical broadcast channel, generates cyclical redundancy check (CRC) bits according to the ordering result, and sends out the CRC bits together with the original information bits; wherein, the method adopts different ordering ways in the situations with two antennas or four antennas. 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] As shown in FIG. 1 , 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] As shown in FIG. 2 , 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 different scram...
