Title:
SIGNALING BETWEEN NODES FOR RESOURCE ALLOCATION
Document Type and Number:
WIPO Patent Application WO/2020/060141
Kind Code:
A1
Abstract:
A method and apparatus for supporting signaling between nodes, e.g., gNB central unit (gNB-CU) and gNB distributed unit (gNB-DU), for efficient resource allocation is provided. The gNB-CU receives a delivery status of downlink (DL) data from a first gNB-DU and a second gNB-DU. The gNB-CU determines that a packet data convergence protocol (PDCP) protocol data unit (PDU) from the DL data does not need to be transmitted to a wireless device based on the delivery status of the DL data. The gNB-CU transmits an indication to at least one gNB-DU among the first gNB-DU and the second gNB-DU. The at least one gNB-DU has the PDCP PDU which does not need to be transmitted to the wireless device. Upon receiving the indication from the gNB-CU, the gNB-DU removes resources for transmitting the PDCP PDU based on the indication.
