Abstract: The present disclosure provides in some embodiments a method and a device for transmitting CSI. The method for transmitting the CSI includes steps of: determining, by a UE, a first number of bits used for a joint encoding operation on a BI and a RI, the BI being configured to indicate an index of a resource for transmitting a reference signal corresponding to the RI measured by the UE, an identical first number of bits being used for the joint encoding operation on RI(s) and the BI corresponding to all resources for transmitting the reference signal; and performing, by the UE, the joint encoding operation on the RI and the BI in accordance with the first number of bits to acquire encoding information, and transmitting the encoding information.

Abstract: A signal processing method and apparatus, a device, and a computer readable storage medium are provided, which relate to the field of communication technology, to reduce collisions of physical broadcast channel (PBCH) demodulation reference signals (DMRSs). The signal processing method provided by embodiments of the present disclosure includes: generating a plurality of candidate PBCH DMRS sequences; acquiring a mapping relationship between PBCH DMRS sequences and resource element (RE) groups; and transmitting the candidate PBCH DMRS sequences by using RE groups corresponding to the candidate PBCH DMRS sequences according to the mapping relationship. Therefore, the embodiments of the present disclosure may reduce collisions of PBCH DMRSs.
