Embodiment Construction

[0081] The specific implementation manner of the present invention will be further described in detail below with reference to the drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0082] Such as figure 1 As shown, the signal processing method of the embodiment of the present invention is applied to the network side equipment, including:

[0083] Step 101, generating candidate PBCH DMRS sequences.

[0084] In the embodiment of the present invention, the network side device may be a base station or the like. On the base station side, usually, there are 8 usable PBCH DMRS sequences generated, so any one of the 8 sequences can be called a candidate (Candidate) PBCH DMRS sequence here.

[0085] There are many ways to generate candidate PBCH DMRS sequences, for example, Gold sequences can be generated according to the methods in the prior art.

[0086] Step 102, obta...

Abstract

The invention provides a signal processing method, device, equipment and computer-readable storage medium, which relate to the technical field of communication and are used for reducing the collision of PBCH DMRS. The signal processing method of the present invention includes: generating a candidate physical broadcast channel demodulation reference symbol PBCH DMRS sequence; obtaining a mapping relationship between a PBCH DMRS sequence and a resource unit RE group; according to the mapping relationship, using the PBCH DMRS sequence corresponding to the candidate PBCH DMRS sequence The RE group transmits the candidate PBCH DMRS sequence. The invention can reduce the collision of PBCH DMRS.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a signal processing method, device, equipment and computer-readable storage medium. Background technique [0002] In the 5th generation mobile communication system, in order to improve the coverage, the synchronization signal block is transmitted by means of beam scanning, that is, different beams are formed at different times to point to the same or different directions to transmit the synchronization signal block. A sync signal block is composed of a sync signal and a physical broadcast channel part. The physical broadcast channel part includes a physical broadcast channel (Physical Broadcast Channel, PBCH) and a demodulation reference symbol (DeModulation Reference Signal, DM RS) of the physical broadcast channel. [0003] The demodulation reference symbol in the physical broadcast channel is used for channel estimation and indicates the (time) sequence numb...
