Abstract: The present disclosure describes methods, system, and devices for configuring hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback for physical downlink shared channel (PDSCH) transmission. The method includes receiving, by a user equipment (UE), a radio resource control (RRC) parameter to configure an enhanced dynamic HARQ-ACK feedback mode; and receiving, by the UE, a first downlink control information (DCI) comprising a first K. The first DCI corresponds to a first PDSCH. The method also includes receiving, by the UE, a second DCI for a second PDSCH, the second DCI comprising a second K with an applicable value; and transmitting, by the UE, an enhanced dynamic HARQ-ACK feedback according to a preset rule.

Abstract: Techniques are described to improve the transmission and reception of access signals such as synchronization signal block (SSB), system information, or paging message. As an example, a wireless communication method is disclosed where a network node, such as a base station, determines a first set of transmission times and/or a second set of transmission times to transmit access signals. The network node transmits the access signals over a wireless channel using the first set of transmission times and/or the second set of transmission times. The access signals can include system information, paging message, or synchronization signal block.
