Synchronous harq
WebA number of embodiments describe synchronous and asynchronous HARQ operations for NextGen Radio (NR) (e.g., 5G) medium access control (MAC). As used herein, a HARQ operation describes one or more HARQ processes that include transmissions and one or more retransmissions based on HARQ feedback acknowledgement (ACK)/negative … WebFeb 1, 2004 · An H-ARQ scheme with energy reduction transmission for the retransmitted subpackets termed energy reduction H-ARQ (ER-HARQ) is proposed and adopted in the …

WebFor both up and downlink a synchronous, single-bit HARQ feedback (ACK/NACK) is sent providing feedback about the success of the previous transmission. The HARQ protocol is adaptive in both uplink and downlink, meaning that the scheduler can decide to use a different resource for a retransmission compared to the previous (re)transmission. WebSynchronous HARQ defines the retransmission timing such that all the HARQ retransmission processes are restricted to occur at known time (usually with a certain …
WebIn the synchronous method of operation, the base station knows exactly when to expect the HARQ Ack/Nack indication and no explicit signaling is required: there is a fixed timing relationship between the over-the-air initial transmission (in above example, time=4) and the transmission of HARQ Ack/Nack by the receiver, also over the air (in above example, … WebSep 9, 2024 · Quick summary.
