SIST EN 301 349 V7.2.1:2005 is the Slovenian adoption of ETSI EN 301 349 V7.2.1 (2000-06) for GSM Phase 2+ GPRS. It specifies the Radio Link Control/Medium Access Control (RLC/MAC) procedures on the Mobile Station (MS) - Base Station System (BSS) interface at the Um radio reference point. In practice, it tells implementers how packet access, paging, Temporary Block Flows (TBFs), block transfer, control messages, measurements, and error handling work between the MS and the network.
What does SIST EN 301 349 V7.2.1:2005 specify?
SIST EN 301 349 V7.2.1:2005 specifies the procedures used at the radio interface for the General Packet Radio Service (GPRS) Medium Access Control / Radio Link Control (MAC/RLC) layer. It applies to the GPRS Um functional layers for Radio Link Control functions and Medium Access Control on packet data physical channels.
Clause 1 states that text marked as “further study”, “FS” or “FFS” is not normative. The rest of the document is organized into scope, references, definitions, layered overview, MAC procedures, paging, MAC procedures on PCCCH, MAC procedures in packet transfer mode, RLC procedures, RLC/MAC block structure, message definitions, information element coding, and timers and counters.

What are the key requirements of SIST EN 301 349 V7.2.1:2005?
Access, paging, and measurements
Clause 5 separates packet idle mode from packet transfer mode. In packet idle mode, no TBF exists and the MS monitors paging subchannels on PCCCH, or on CCCH if PCCCH is not present. In packet transfer mode, the MS is assigned radio resources for point-to-point transfer over one or more PDCHs.
This matters because it defines when the MS listens and when it can send or receive packet data. The same clause also links packet idle mode to later TBF establishment when upper layers need to transfer an LLC PDU.
Clause 6 lets the network page for RR connection establishment or downlink packet transfer on CCCH or PCCCH, and in packet transfer mode on PACCH. A single paging message can address several mobile stations, which matters for network efficiency and for how paging capacity is planned.
Clause 5.6 and clauses 7.3 and 8.3 define measurement reporting. The network may request NC measurement reports in MM Ready state and EM reports in packet idle mode, and the MS sends reporting when timers such as T3158 or T3178 expire. In practice, this ties radio measurements to scheduled reporting periods rather than ad hoc transmission.
Temporary Block Flows and radio resource assignment
Clause 7 defines TBF establishment initiated by either the MS or the network. When PCCCH is available, packet access uses PCCCH; otherwise the procedures fall back to CCCH as defined in GSM 04.08. The clause covers one-phase and two-phase access, contention resolution, timing advance, and abnormal cases.
This matters because the standard separates how uplink resources are requested from how downlink resources are assigned. Implementers have to support both the request/response flow and the recovery paths when access fails or collides.
Clause 8.1 states that uplink and downlink RLC data block transfer can use dynamic allocation, extended dynamic allocation, or fixed allocation. The MAC mode is signalled in assignment messages, and Packet Uplink Assignment and Packet Downlink Assignment carry the parameters the MS needs for timing, frequency, power, and timeslot use.
Clause 8.2 adds PACKET PDCH RELEASE, which informs the MS that one or more timeslots are no longer available. In practice, the terminal must stop using the released channel immediately and update its allocation state.
RLC operation and reliability
Clause 9 defines the RLC procedures in packet transfer mode. RLC supports both acknowledged mode and unacknowledged mode: acknowledged mode uses selective retransmission and preserves PDU order, while unacknowledged mode does not retransmit lost blocks.
This matters because the application decides whether it values reliability or lower protocol overhead. Clause 9 also defines the peer-to-peer variables and windows used for acknowledged operation, including V(S), V(A), V(B), V(R), V(Q), BSN, SSN and RBB.
Clause 9.1 and clause 12.3 define segmentation and reassembly of LLC PDUs into RLC data units, and the Ack/Nack Description used for block acknowledgement. The receiver uses the block bitmap to acknowledge or reject individual RLC data blocks, which is the basis for retransmission control.
Block structure and header fields
Clause 10 defines the RLC/MAC block as a MAC header plus either an RLC data block or an RLC/MAC control block. Spare bits are set to 0 by the sender and ignored by the receiver.
This matters because every transmitted block has a strict on-air structure. Clause 10 also states that RLC data blocks may use CS-1, CS-2, CS-3 or CS-4, while RLC/MAC control blocks use CS-1.
Clause 10.4 defines the main header fields that control sharing and feedback: USF, R, SI, S/P, RRBP, CV, FBI, TI, AC, FS, RTI, D, TFI, BSN, LI and control message contents. In practice, these fields tell the peer when it may transmit, what flow the block belongs to, whether a block closes a flow, and how to parse segmented control messages.
Control messages, information elements, and cell parameters
Clause 11 defines the functional content of RLC/MAC control messages such as Packet Channel Request, Packet Downlink Assignment, Packet Uplink Assignment, Packet Downlink Ack/Nack, Packet Uplink Ack/Nack, Packet Paging Request, Packet PDCH Release, Packet Measurement Report, Packet TBF Release, Packet System Information messages, and Packet Timeslot Reconfigure.
This matters because the standard is not only about data transfer - it also defines the signalling vocabulary used to set up, modify, and release GPRS radio resources. Clause 11.1 also makes error handling mandatory for the MS when protocol data are unknown or erroneous.
Clause 12 defines reusable information elements such as Ack/Nack Description, ALLOCATION_BITMAP, Channel Request Description, Frequency Parameters, Global Power Control Parameters, Global TFI, Packet Request Reference, Packet Timing Advance, Power Control Parameters, PRACH Control Parameters, TFI, TLLI, TQI, TIMESLOT_ALLOCATION, TS_OVERRIDE, PAGE_MODE, Starting Frame Number Description, Cell Identification, GPRS Cell Options, PCCCH Organization Parameters, Extension Bits IE, Non GPRS Cell Options IE, and LSA Parameters. These IEs are the encoded building blocks used across multiple control messages, so they are central to implementation and interoperability.
Timers, counters, and recovery
Clause 13 defines timers and counters on both the MS side and the network side. The timers and counters govern measurement reporting, resource supervision, and abnormal release behavior, including cases such as T3158, T3169, T3191, N3101, N3102 and N3103.
In practice, these mechanisms stop stalled procedures from continuing indefinitely and define when the network or the MS must release resources, retry, or reselect a cell.
What terms does SIST EN 301 349 V7.2.1:2005 define?
- Block period - A block period is the sequence of four timeslots on a Packet Data Channel (PDCH) used to convey one radio block.
- GPRS multislot class - A GPRS multislot class describes which combinations of multiple PDCHs a mobile station can transmit and receive on.
- Temporary Block Flow (TBF) - A TBF is the temporary point-to-point radio resource used for signalling or user data transfer between the network and one MS.
- Temporary Flow Identifier (TFI) - The TFI uniquely identifies a single uplink or downlink TBF.
- Temporary Logical Link Identity (TLLI) - The TLLI is the identifier associated with the GPRS subscriber at the radio interface.
- Temporary Queueing Identifier (TQI) - The TQI identifies a mobile station during the queueing procedure and its contents are operator defined.
- Uplink State Flag (USF) - The USF tells the MS when it is allowed to transmit uplink data in a shared channel block.
- Ack/Nack Description - This information element carries the sequence number and bitmap used to acknowledge or negatively acknowledge a group of RLC data blocks.
Who uses SIST EN 301 349 V7.2.1:2005?
SIST EN 301 349 V7.2.1:2005 is used by engineers who design GSM/GPRS mobile stations and base station subsystem software, especially the MAC and RLC layers.
