Consider TTI = 20ms
peak data rate = 64 kbps
trasnport block size = 336 bits
RLC SDU size = 500 bytes
SN=6, 8 are dropped.
SN = Sequence Number
P = Poll bit
The physical layer combines the transport blocks together, interleaves them and then transmits them via two radio frames.
Thus, RLC PDUs in the receiver cannot be recovered until all [...]
There are 4 use cases for STATUS PDU:
1. By the receiver to inform the sender about missing and received AMD PDUs.
2. By the sender to request the receiver to move the reception window
3. By the receiver to acknowledge the sender about the reception of the request to move the window
4. By the receiver to inform [...]
There are two types of PDUs in RLC/AM:
1. AM data (AMD) PDUs: user data
2. AM control PDUs
AM control PDUs are further classified into:
1. STATUS PDU
2. Piggybacked STATUS PDU
3. RESET and RESET ACK PDU
