The aim of the test code test_pdcp_rlc.c is primarily to test a PDCP protocol entity integrated with RLC layer.
|
|
This is a first step, in near future, this test may be extended with an other type of RLC (AM), and may be
|
|
integrated with the upcoming traffic generator.

Q:How to send a SDU?
|
|
A:
|
|
pdcp_rlc_test_send_sdu(0, 1, 2); // prototype pdcp_rlc_test_send_sdu(module_id_t module_idP, rb_id_t rab_idP, int sdu_indexP)

Q:How to fix the bitrate of the radio bearer?
|
|
A:
|
|
pdcp_rlc_test_exchange_pdus(&rlc[0].m_rlc_um_array[rlc[0].m_rlc_pointer[1].rlc_index],
|
|
&rlc[1].m_rlc_um_array[rlc[1].m_rlc_pointer[1].rlc_index],
|
|
1000,
|
|
1000);
|
|
|
|
Prototype:
|
|
pdcp_rlc_test_exchange_pdus(rlc_um_entity_t *um1P, // RLC UM instance 1
|
|
rlc_um_entity_t *um2P, // RLC UM instance 2
|
|
u16_t bytes_tx1P, // tx bytes requested at RLC UM instance 1 and sent to RLC UM instance 2
|
|
u16_t bytes_tx2P) // tx bytes requested at RLC UM instance 2 and sent to RLC UM instance 1
