`
`Definitions
`3.1
`For the purposes of the present document, the following terms and definitions apply:
`
`TG: Transmission Gap is consecutive empty slots that have been obtained with a transmission time reduction method.
`The transmission gap can be contained in one or two consecutive radio frames.
`
`TGL: Transmission Gap Length is the number of consecutive empty slots that have been obtained with a transmission
`time reduction method. 0 ≤TGL≤ 14. The CFNs of the radio frames containing the first empty slot of the transmission
`gaps, the CFNs of the radio frames containing the last empty slot, the respective positions Nfirst and Nlast within these
`frames of the first and last empty slots of the transmission gaps, and the transmission gap lengths can be calculated with
`the compressed mode parameters described in [5].

`Multiplexing, channel coding and interleaving
`
`General
`4.1
`Data stream from/to MAC and higher layers (Transport block / Transport block set) is encoded/decoded to offer
`transport services over the radio transmission link. Channel coding scheme is a combination of error detection, error
`correcting, rate matching, interleaving and transport channels mapping onto/splitting from physical channels.
`
`General coding/multiplexing of TrCHs
`4.2
`This section only applies to the transport channels: DCH, RACH, CPCH, DSCH, BCH, FACH and PCH. Other
`transport channels which do not use the general method are described separately below.
`
`Data arrives to the coding/multiplexing unit in form of transport block sets once every transmission time interval. The
`transmission time interval is transport-channel specific from the set {10 ms, 20 ms, 40 ms, 80 ms}.
`
`The following coding/multiplexing steps can be identified:
`
`- add CRC to each transport block (see subclause 4.2.1);
`
`IPR2018-01556
`HTC v. INVT
`INVT Exhibit 2002 - Page 9
`
`

`

`-
`
`transport block concatenation and code block segmentation (see subclause 4.2.2);
`
`- channel coding (see subclause 4.2.3);
`
`-
`
`-
`
`-
`
`-
`
`-
`
`radio frame equalisation (see subclause 4.2.4);
`
`rate matching (see subclause 4.2.7);
`
`insertion of discontinuous transmission (DTX) indication bits (see subclause 4.2.9);
`
`interleaving (two steps, see subclauses 4.2.5 and 4.2.11);
`
`radio frame segmentation (see subclause 4.2.6);
`
`- multiplexing of transport channels (see subclause 4.2.8);
`
`- physical channel segmentation (see subclause 4.2.10);
`
`- mapping to physical channels (see subclause 4.2.12).
`
`The coding/multiplexing steps for uplink and downlink are shown in figure 1 and figure 2 respectively.

`Figure 2: Transport channel multiplexing structure for downlink
`
`The single output data stream from the TrCH multiplexing, including DTX indication bits in downlink, is denoted
`Coded Composite Transport Channel (CCTrCH). A CCTrCH can be mapped to one or several physical channels.

`CRC attachment
`4.2.1
`Error detection is provided on transport blocks through a Cyclic Redundancy Check (CRC). The size of the CRC is 24,
`16, 12, 8 or 0 bits and it is signalled from higher layers what CRC size that should be used for each TrCH.
`
`CRC Calculation
`4.2.1.1
`The entire transport block is used to calculate the CRC parity bits for each transport block. The parity bits are generated
`by one of the following cyclic generator polynomials:
`
`- gCRC24(D) = D24 + D23 + D6 + D5 + D + 1;
`
`- gCRC16(D) = D16 + D12 + D5 + 1;
`
`- gCRC12(D) = D12 + D11 + D3 + D2 + D + 1;
`- gCRC8(D) = D8 + D7 + D4 + D3 + D + 1.
