General control signals for efficient system operation
TLDR
In this paper, the authors proposed the slot format indicator (SFI) for the slot (68a) and determined the type of each of the symbols in the slot based on the number of uplink and downlink symbols.Abstract:
FIELD: wireless communication.SUBSTANCE: invention relates to the field of control signaling in a wireless communication system. Effect is achieved by following: in a wireless communication system (100), the access node (110) configures for a user device (UE) (105) each symbol in the slot (68a) separately as one of a plurality of possible symbol types. The types include an uplink symbol, a downlink symbol, and other symbol. The access node (110) transmits to the UE (105) an SFI determining the number of downlink symbols in the slot (68a) and the number of uplink symbols in the slot (68a) and indicating whether the slot (68a) includes other symbols. The UE (105) receives from the access node (110) the SFI for the slot (68a) and determines the type of each of the symbols in the slot (68a) based on the number of uplink symbols and the number of downlink symbols.EFFECT: technical result consists in ensuring the transmission of the slot format indicator (SFI) in efficient way.30 cl, 23 dwgread more
