7. How an established radio link works
On an established link, the terminal must be able to identify, on the downstream channel, the resources to be listened to in order to decode the packets intended for it, and, on the upstream channel, the resources it can use to transmit its data. This is the resource allocation mechanism. In addition, it needs reference signals to analyze the channel and demodulate the signal correctly, especially in the case of multi-antenna transmission.
7.1 Resource allowance
On the 4G-LTE radio interface, resource allocation for the downlink or uplink channel is systematically performed on the first symbols of each 1 ms subframe, and the allocation message is spread over the entire band.
The mechanism is more flexible in 5G-NR. Allocation is indicated...
