3.1 Definitions
For the purposes of the present document, the following terms and definitions apply.
TrCH number: The transport channel number identifies a TrCH in the context of L1. The L3 transport channel identity (TrCH ID) maps onto the L1 transport channel number. The mapping between the transport channel number and the TrCH ID is as follows: TrCH 1 corresponds to the TrCH with the lowest TrCH ID, TrCH 2 corresponds to the TrCH with the next lowest TrCH ID and so on.
3.2 Symbols
For the purposes of the present document, the following symbols apply:
x round towards , i.e. integer such that x x < x+1
x round towards –, i.e. integer such that x-1 < x x
x absolute value of x
Unless otherwise is explicitly stated when the symbol is used, the meaning of the following symbols are:
i TrCH number
