RLC-ARQ

  • Can Anyone tell me ARQ Procedure in RLC is used in which Context i mean in terms of UL or DL?

  • What i figured out is for ARQ, there is no context specific to UL or DL, it is context of transmitter and receiver. One can be receiver or transmitter(one at a time) so whoever is transmitter executes polling procedure and whoever is receiver executes status reporting which together completes the ARQ procedure and initiate retransmission of lost or discarded packet at transmitter end.

    Thank you.

  • Now what i want to know is who decides the window size in RLC entity?

  • RRC configures Tx_Window_Size and Rx_Window_Size in RLC .
