The field mapping convention in this clause is that when a field is contained within a single octet, the highest bit number of the field represents the highest order value and lowest bit number of the field represents the lowest order value.

Spare bits are encoded with the binary value "0". Fill octets are encoded with the binary value "00101011".

Two alternative PTCCH uplink block formats are specified. The originally 8 bit (1 octet) blocks are used uplink in the following way.

Figure 7.11 (sheet 2 of 2): PTCCH uplink block format

The field mapping convention of clause 7.10 applies. In the addition, when a field spans more than one octet, the order of bit values within each octet progressively decreases as the octet number increases. In that part of a field contained in a given octet the lowest bit number represents the lowest order value.

7.10 Order of bit transmission

On channels for normal burst transmission having a block format with an integer N number of octets, the N octets are mapped onto 8N bits, d(0) to d(8N-1), defined in 3GPP TS 05.03 clauses 4 and 5 as follows:

Bit m of octet n shall be transmitted as bit d((n‑1)*8+m‑1) with m=(1..8) and n=(1..N).

On channels for normal burst transmission having a block format with a non-integer number of octets, or for transmission having a defined block format but which does not follow the normal burst transmission, the octets are mapped onto M bits, d(0) to d(M-1), defined in 3GPP TS 05.03 clause 5 as follows:

Bit m of octet n shall be transmitted as bit d(8(n‑1) + m‑1) with n = (1 .. ((M-1) DIV 8) + 1)) and m = (1 .. min (8, (M – 8(n-1))), and where ‘DIV’ is the integer division operator.
