* libosmogsm/l1sap.h: extend ph_rach_ind_param with lqual_cbVadim Yanitskiy2019-07-101-0/+1
| | | | | | | | | | | | The link quality, defined by C/I (Carrier-to-Interference) ratio, can be computed from the training sequence of each burst, where we can compare the "ideal" training sequence with the actual training sequence and then express that in cB (centiBels, dB * 10). By analogy with both RSSI and ToA, it can be used to filter out false-positive detections and ghost Access Bursts. Change-Id: Ie2a66ebd040b61d6daf49e04bf8a84d3d64764ee
* l1sap: Add fields for higher-precision timing offset valuesHarald Welte2018-02-271-2/+8
| | | | | | | | | | | | So far, we used quarter-bits across the L1SAP between the hardware/PHY specific part of OsmoBTS and the common part. In order to increase the resolution, let's add fields/members for 1/256th bit. In order to keep ABI and API compatibility, we use a union around the old and new values, so old code will still compile + work withe new libosmocore.

* l1sap: Add RSSI, BER and quarter-bit accurate timing to PH-RACH.indHarald Welte2018-02-271-0/+4
| | | | | | | | Let's extend PH-RACH.ind with some useful data across the L1SAP boundary. Change-Id: I9439810c3a3ad89ea0302753617b850749af887c Related: OS#3003
* l1sap.h: Add ber10k and lqual_cb to ph_tch_paramPau Espin Pedrol2017-06-301-0/+2
| | | | | | | These fields are required in osmo-bts to do low link quality checks in a generic way. Change-Id: If4ae20c22b881e94585dad710f17b9e37f77bf82
* doxygen: unify use of \file across the boardNeels Hofmeyr2017-06-231-0/+2
| | | | | | | | | | | | | | | | | Considering the various styles and implications found in the sources, edit scores of files to follow the same API doc guidelines around the doxygen grouping and the \file tag. Many files now show a short description in the generated API doc that was so far only available as C comment. The guidelines and reasoning behind it is documented at https://osmocom.org/projects/cellular-infrastructure/wiki/Guidelines_for_API_documentation In some instances, remove file comments and add to the corresponding group instead, to be shared among several files (e.g. bitvec).

* doxygen: enable AUTOBRIEF, drop \briefNeels Hofmeyr2017-06-231-77/+77
| | | | | | | | | | Especially for short descriptions, it is annoying to have to type \brief for every single API doc. Drop all \brief and enable the AUTOBRIEF feature of doxygen, which always takes the first sentence of an API doc as the brief description. Change-Id: I11a8a821b065a128108641a2a63fb5a2b1916e87
* l1sap: Add frame-number to measurement indication structPhilipp Maier2017-05-171-0/+1
| | | | | | | | The distribution of the channel measurement calculations over multiple timeslots (continous calculation) requires to keep track of the frame number in struct info_meas_ind_param Change-Id: I8c783b4a92ae2c3cc5d17936a146eb49d47eac37
* Add Marker to ph_tch_paramMax2016-09-091-0/+1
| | | | | | | | Extend struct ph_tch_param with Marker bit from RTP header to indicate speech onset in case of DTX. Change-Id: Ic664902630b9d335ff9abc7a9ca7249eaf80e05f Related: OS#1750
* Extend L1SAP with MeasurementsMax2016-08-041-0/+3
| | | | | | | | We already have RSSI parameter in PH-DATA. Add other measurement information (BER, BTO, Link Quality). Change-Id: I2b127eb1856c4cd1bc46490a89592a595f1ee86b Related: OS#1616
* Update structure in libosmocore for 11 bit RACHbhargava2016-07-241-1/+11
| | | | | | | | Parameters are added to the structure ph_rach_ind_param to differentiate the type of RACH received from Layer 1. This is to further support the 11 bit RACH. Change-Id: Ic4f0f2424a3af7599d986044be25ea4fcc0ca477
* Add strings with PH primitive namesMax2016-05-301-0/+2
| | | | | | | | | | It's useful debugging helper while troubleshooting L1-related issues.

* Extend L1SAP PH-DATA with presence informationMax2016-02-221-0/+11
| | | | | | | | | Previously the presence of header and data blocks were communicated in-band which decreases code readability and makes it unnecessary hard to add support for new hardware. Note: OsmoBTS have to be modified to take advantage of extended ph_data_param structure.

* Add chan_nr to RACH info at L1SAP interfaceAndreas Eversberg2013-07-061-0/+1
| | | | | The chan_nr is required to locate timeslot and subslot of access bursts during handover procedure.

* Add MPH and TCH primitives to layer 1 SAPAndreas Eversberg2013-07-061-3/+72
| | | | | | | | | | | | | In order to control layer 1 via primitives, MPH primitives are required. There is only one (MPH-INFO) primitive defined in TS 04.04 for all control and measurement functions. A type identifier inside this primitive is used to differentiate between different functions. The TCH primitives are used to carry traffic. TCH primitives carry voice or data traffic, whereas PH-DATA primitives carry FACCH data. PH_RTS and TCH_RTS (ready-to-send) primitives are used to poll requests from upper layers.
* Remove osmo_phsap_prim from lapdm.h and move to a seperate header fileAndreas Eversberg2013-07-061-0/+53
