Title:
SSB CANDIDATE POSITION INDEX INDICATION METHOD AND APPARATUS, SSB CANDIDATE POSITION INDEX RECEIVING METHOD AND APPARATUS, STORAGE MEDIUM, BASE STATION, AND USER EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2021/027694
Kind Code:
A1
Abstract:
An SSB candidate position index indication method and apparatus, an SSB candidate position index receiving method and apparatus, a storage medium, a base station, and a user equipment. The SSB candidate position index indication method comprises: determining the maximum number of SSB candidate position indexes capable of being sent in a DRS transmission window under the current subcarrier space; determining the number of bits occupied for sending the SSB candidate position indexes according to the maximum number of the SSB candidate position indexes; determining to indicate the SSB candidate position indexes by adopting the highest P bits in a PBCH payload and a sequence of a DMRS according to the number of bits, or indicate the SSB candidate position indexes by adopting original SSB index bits and newly added index bits in the PBCH load, wherein the sequence of the DMRS occupies Q bits, and P is a difference between the number of bits and Q; and sending an SSB, the SSB comprising the PBCH payload. According to the technical solution of the present invention, the SSB candidate position index can be indicated in an unlicensed frequency band higher than 6 GHz.
