OsmocomBB

As was discussed with Harald and Eric, the TDMA scheduler from trxcon should be integrated into osmo-trx-ms for the sake of minimizing delays. This can be achieved by separating trxcon's major components into shared libraries, let's say: libosmobb-l1sched.so, libosmobb-l1ctl.so, and libosmobb-trxif.so (naming suggestions are welcome!).

Scheduler interface¶

Clock¶

• trx_data_rx_cb()
• sched_clck_handle()

Uplink path¶

• trx_data_rx_cb()
• sched_trx_handle_rx_burst()
• lchan_handler(), e.g. rx_data_fn()
• (... burst buffers ... )
• sched_send_dt_ind()
• l1ctl_tx_dt_ind()
• l1ctl_link_send()

Downlink path¶

• l1ctl_rx_dt_req()
• sched_prim_init() & sched_prim_push()
• (... prim queue ...)
• sched_frame_clck_cb()
• lchan_handler()
• trx_if_tx_burst()
