Title: INDICATION OF HYBRID AUTOMATIC REPEAT REQUEST FEEDBACK BY SYNCHRONIZATION SIGNAL
Abstract:
A node (100) of a wireless communication network receives a synchronization signal from a radio device (10). Based on the received synchronization signal, the node determines a time alignment configuration for uplink radio transmissions from the radio device to the wireless communication network. Based on the received synchronization signal, the node further determines Hybrid Automatic Repeat Request feedback information for at least one downlink radio transmission from the wireless communication network to the radio device (10). The node (100) indicates the determined time alignment configuration to the radio device (10). Based on the determined Hybrid Automatic Repeat Request feedback information, the node controls retransmission of the at least one downlink radio transmission.
