Document Type and Number:
WIPO Patent Application WO/2021/012738
Kind Code:
A1
Abstract:
A synchronization signal block sending method and apparatus, a slot position determination method and apparatus, a storage medium, a base station and a terminal. The sending method comprises: acquiring a synchronization signal block set to be sent, wherein the synchronization signal block set comprises n synchronization signal blocks; for the ith synchronization signal block, respectively mapping a plurality of signals or channels comprised in the ith synchronization signal block to the same slot of different frames within a transmission window, and enabling the same signals or channels of different synchronization signal blocks in the synchronization signal block set to be located in different slots of the same frame; and within the transmission window, sending the synchronization signal block set according to a mapping pattern obtained by means of mapping. By means of the solution of the present invention, a synchronization signal block set suitable for narrowband transmission can be provided to support synchronization signal blocks for multi-beam transmission. Further, in consideration of flexible uplink and downlink slot configurations in an NR system, the solution of the present invention provides a more rational mapping pattern for a time-domain synchronization signal block, which can facilitate the transmission of a synchronization signal block set.
