Embodiment Construction

[0025] figure 1 A group-based HARQ-ACK feedback process 100 according to some embodiments of the invention is shown. Process 100 may be performed between UE 110 and a BS belonging to wireless communication system 101 . In some examples, system 101 employs a fifth-generation (5G) New Radio (NR) air interface developed by the 3rd Generation Partnership Project (3GPP). In some examples, system 100 employs other wireless communication technologies developed by various standards development organizations.

[0026] In some examples, BS 120 may be a base station implementing a gNB node as defined in the 5G NR air interface standard developed by 3GPP. In an example, BS 120 can be configured to control one or more antenna arrays to form directional Tx or Rx beams for transmitting or receiving wireless signals. UE 110 may be a mobile phone, laptop computer, vehicle-mounted mobile communication device, utility meter fixed at a particular location, or the like. Similarly, in one examp...

Abstract

A method can include receiving one or more downlink control informations (DCIs) that are associated with first downlink transmissions belonging to a first hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback group at a user equipment (UE) in a wireless communication system, receiving a first request that indicates a first group index (GI) of the first HARQ-ACK feedback group and a first HARQ-ACK transmission opportunity (TxOP), and transmitting first acknowledge bits for acknowledging receptions of downlink transmissions belonging to the first HARQ-ACK feedback group over the first HARQ-ACK TxOP indicated by the first request.
