Splet31. mar. 2024 · For example, 15kHz SCS with 14 symbols spanning the entire subframe corresponds to LTE's configuration. At 240kHz SCS (for control only), 14 symbols are squeezed into a 62.5µs slot. In Release 16, 120kHz is the maximum SCS allowed for data. Hence, the lowest achievable slot duration is 125µs. Spletprbset contains the physical resource block (PRB) indices corresponding to the resource allocation for this PDSCH transmission. You can specify prbset as either a column vector or a two-column matrix. If you specify a column vector, the resource allocation is the same in both slots of the subframe.

Splet22. okt. 2024 · There are 4 aggregation layers in the normal PDCCH – Aggregation layer 1 : This uses 1 CCE and it is the smallest block so it is only used in very good radio conditions. – Aggregation layer 2 : This uses 2 CCEs and it is usually the most common aggregation layer in normal radio conditions. SpletThis MATLAB function performs the inverse of physical downlink shared channel (PDSCH) processing on the matrix of complex modulated PDSCH symbols, sym, using cell-wide …

Splet5.5.4 PUCCH resource allocation. Before carrier aggregation is introduced into the LTE system, the ACK/NACK information corresponding to the PDSCH scheduled by a DCI is transmitted on a PUCCH format 1a/1b resource, which is determined based on the first CCE occupied by the DCI. Splet11. apr. 2024 · The resource allocation methods of the above work have a high computational complexity and the system performance still has room for improvement. For settling the above issues, this paper firstly designs a NOMA-based model of a power IoT network for downlink transmission of URLLC and eMBB hybrid service scenarios.
