WebMay 13, 2024 · PHICH is a control channel on LTE downlink, that is used to acknowledge the reception of uplink (PUSCH)transmission from a mobile/UE. The PHICH indicates either a ACK or a NACK, which the UE will decode to find out if it has to do a retransmission or not. The ACK/Nack is indicated by the Enodeb. Encoding Of PHICH WebOct 17, 2014 · The UE after decoding the DCI-0 will transmit the PUSCH in subframe-4 with the parameters as conveyed in the DCI-0. Now eNodeB knows that it has sent a uplink grant to the UE in subframe-0 and and now it is expecting a PUSCH from that UE, in subframe-4. So the eNodeB L2 will give the configurations needed to decode the PUSCH to L1 in … WebApr 11, 2024 · MIB will transmit the DL bandwidth and parameter called Ng, These two parameter used to decide no of PHICH groups.Ng will be decided by higher layers.Increased no of PHICH will support more UE to receive the ACK/NACK.
