FEEDBACK TECHNIQUES FOR GROUP-COMMON PDCCH TRANSMISSIONS

Abstract:

A user equipment (UE) may receive a first group downlink control information transmission associated with a UE group, where the first group downlink control information transmission may reference a second group downlink control information transmission (e.g., according to a pre-notification indication). The UE may determine a feedback condition for the second group downlink control information transmission and monitor for the second group downlink control information transmission. Alternatively, the UE may receive a second group downlink control information transmission referencing the first group downlink control information transmission (e.g., according to a post-confirmation indication), and the UE may determine a feedback condition for the first group downlink control information transmission. Based on the feedback condition, the UE may transmit feedback information, for example, indicating that the UE did not correctly receive the indicated group downlink control information transmission.
