How about sending PHICH 4 ms after the first PUSCH in the TTI ? If there's an error, only that CBG is retransmitted, not the entire TB. TxTI Transmitted Trace Identifier UNI User-to-Network Interface VCG Virtual Concatenation Group VCOH Virtual Concatenation Overhead vcPT virtual concatenated Payload Type 3 What is OTN/OTH 3.1 OTN Standards There are many standards that fall under the umbrella of "OTN". At 60kHz, there's an option to use extended cyclic prefix (CP), thus limiting the slot duration to 12 symbols. When a UE is configured with higher layer parameter ttiBundling and configured with higher layer parameter e-HARQPattern-r12 set to FALSE or not configured, for FDD and subframe bundling operation, the UE shall upon detection of a PDCCH/EPDCCH with DCI format 0 in subframe n intended for the UE, and/or a PHICH transmission in subframe n-5 intended for the UE, adjust the corresponding first PUSCH transmission in the bundle in subframe n+4 according to the PDCCH/EPDCCH and PHICH information. With fewer bits, errors at CBG are less likely than at TB. It means Network can send DL control information in any subframe and UE can send UL control information in any subframe.

Prada Campaign 2020, Pipeline processing is possible because time-domain interleaving is not done. Then map it to a number of Resource Blocks using the table above. In the frequency domain, different numerologies are permitted, corresponding to different Sub-Carrier Spacing (SCS). This means that in deployments where there's a long delay spread, CP will not offer sufficient protection against inter-symbol interference (ISI). And I found some technical background for this from 3GPP However, after it hits a peak (point (2)), the overhead caused by the increasing CP length is more dominant than the increased robustness. Followings are proposed by Huawei and HiSilicon in, In real application, this proposal envison the possibility of using all these structure multiplexed together as illustrated below. Due to this, the symbol length in this frame can be 4 times shorter than LTE/LTE-A symbol length. With instant access in the uplink (= allowing the UE to transmit when it gets data on a pre-established grant) or by reducing the TTI and processing times to 1/2ms the download performance can be improved significantly, i.e. Processing can be decoupled from TTI duration. And I found some technical background for this from 3GPP The main reason is pretty obvious. conhecer a extenso da possvel interferncia. By combining different number of symbols, different TTIdurations are possible. 2018. 2) due to sub-frame type, where DL data can reduce and UL data can increase, how would the TTI data fit if the allowed DL data rate changes as per the sub-frame selected. In 3GPP 36.321 5.4.2.1 HARQ entity, you may find the answer to these questions as below : When TTI bundling is configured, the parameter TTI_BUNDLE_SIZE provides the number of TTIs of a TTI bundle. influncia significativa do tempo e da embalagem sobre os pigmentos analisados (p Any use, reproduction, distribution, marketing, modification of all or part of thehttps://www.ttinteractive.com/website, without the authorisation of the Publisher, is prohibited and may result in legal action and prosecution as provided for in the Intellectual Property Code and the Civil Code. 1,00 TTI bundling is when the same TB is transmitted across multiple TTIs.
