Using the dual decomposition technique, the NUM problem is decomposed into four subproblems — flow control; next-hop routing; rate allocation and scheduling; power control; and channel allocation — and finally
Learn about downlink data transmission in 5G NR. Explore the downlink shared channel chain, which includes LDPC coding, layer mapping, resource element allocation for PDSCH transmission, PDSCH mapping, and precoding.
5G NR Physical Uplink Shared Channel (PUSCH) From the series: 5G Tutorial Learn about the physical uplink shared channel (PUSCH) and its processing chain, which includes elements already found in the downlink shared channel chain including LDPC coding, modulation schemes, layer mapping,...

A problem with this uncoordinated scheme is that it requires changes to the existing IEEE 802.15.4 standard in MAC layer. (d) Femtocell & Femtocell A fully distributed method is proposed in [126] for dynamic spectrum sharing between femtocells. First, the available frequency band is divided ...

(depending on the SNR, thepropagation conditionsand the antenna configurations) through a precoding along preferred directions in combination with appropriatepower allocation, i.e., via matrixQ. Ultimately, we have observed that the optimal allocation is sometimes to transmit the total available power ...
You can also use deep learning techniques to perform channel estimation. For example, by viewing the resource grid as a 2-D image, you can turn the problem of channel estimation into an image processing problem, similar to denoising or super-resolution, where CNNs are effective. ...
Game theory is a powerful distributed method in solving the channel allocation problem in wireless networks [14,15,16,17]. In this article, we formulate the POC accessing problem as a QoE maximization game. By utilizing the approximate relationship between interference and QoE, the game is proved...
When a gNB pre-define large number of parameters in the GF configuration, there may be less resource re-allocation flexibility. The network may configure the number of parameters in the pre-defined GF configuration based on many factors such as the service requirements and deployment scenario. ...
