Number of harq processes
Web18 okt. 2024 · Types of HARQ are classified according to how packets are retransmitted and combined. They are the “Incremental Redundancy” (IR) method and the “Chase Combining” (CC) method. The HARQ method enables efficient error control by performing both error correction and retransmission. 4 Analytical Markov Chain Model Web22 dec. 2024 · The HARQ time line is mainly comprised by the processing time, which may scale with the TTI length [], and the propagation time, which is independent of the TTI length.In the model, we take into account the scalability of the processing time, by equating \(n_1=n_2\) and \(n_3=n_4\).Since we are mostly interested in URLLC applications …

Web1 mei 2024 · Maximum number of HARQ processes was set to 8 in LTE but is increased to 16 in NR. This was motivated by shorter time slot and increased use of remote radio …
WebStop-and-wait is simpler, but waiting for the receiver's acknowledgment reduces efficiency. Thus multiple stop-and-wait HARQ processes are often done in parallel in practice: when one HARQ process is waiting for an acknowledgment, another process can use the channel to send some more data. Web1 sep. 2016 · What’s more, the potential large UL/DL asymmetry and limited transmit power in UL According to [ 4 ], when the UL/DL configuration is set to 5 in the case of 5 CCs, the maximum number of DL HARQ processes can reach 75.
Web15 jul. 2014 · As TTI is 1 ms, one HARQ is occupied for 8 ms. What it means is, one HARQ is occupied for atleast 8ms before we can re-use it. Here, 4 ms = propagation time + processing time. For TDD, as radio frame structure is different for different configuration, we have different number of HARQ processes as per configuration. WebJust to give you an practical aspect of Asynchronous HARQ, it operates the multiple HARQ processes in any order.

WebHARQ process ID for the first PDSCH is based on the indicated HARQ process ID in the DCI and increased by 1 for subsequent PDSCHs. NDI and RV bitmap for each scheduled PDSCH is included in the DCI. A single PDSCH-to-HARQ_feedback timing indicator is used to indicate the slot offset between the last scheduled PDSCH and PUCCH.
