Wireless communication methods and devices at user devices

Abstract

The invention proposes methods, systems, machines and devices for wireless communication. User equipment (UE) can be configured to perform group transmission over a sub-link of a high-frequency band, such as millimeter wave (mmW). The UE can transmit, over the sub-link, multiple directed packet beam iterations in various directions corresponding to multiple Quality of Service (QoS) profiles configured for packet transmission. The UE can identify precoding sets for transmitting packets in multiple directions. Packet repeaters can be linked to a separate hybrid automatic repeat request (HARQ) procedure. The UE can rotate the precoding set to transmit packets in multiple directions, and the UE can retransmit packets in the direction where the initial transmission failed.
