5.7.2 导频序列生成
The random access preambles are generated from Zadoff-Chu sequences with zero correlation zone, generated from one or several root Zadoff-Chu sequences. The network configures the set of preamble sequences the UE is allowed to use. There are 64 preambles available in each cell. The set of 64 preamble sequences in a cell is found by including first, in the order of increasing cyclic shift, all the available cyclic shifts of a root Zadoff-Chu sequence with the logical index RACH_ROOT_SEQUENCE, where RACH_ROOT_SEQUENCE is broadcasted as part of the System Information. Additional preamble sequences, in case 64 preambles cannot be generated from a single root Zadoff-Chu sequence, are obtained from the root sequences with the consecutive logical indexes until all the 64 sequences are found. The logical root sequence order is cyclic: the logical index 0 is consecutive to 837. The relation between a logical root sequence index and physical root sequence index u is given by Tables 5.7.2-4 and 5.7.2-5 for preamble formats 0 – 3 and 4, respectively.
The uth root Zadoff-Chu sequence is defined by
xu?n??e?j?un(n?1)NZC,0?n?NZC?1
where the length NZC of the Zadoff-Chu sequence is given by Table 5.7.2-1. From the uth root Zadoff-Chu sequence, random access preambles with zero correlation zones of length NCS?1are defined by cyclic shifts according to
xu,v(n)?xu((n?Cv)modNZC)
where the cyclic shift is given by
?vNCS??Cv??0?RARA??dvn?(vmodn)NCSstartshiftshift????v?0,1,...,??NZCNCS???1,NCS?0for unrestricted setsNCS?0for unrestricted sets
RARARAfor restricted setsv?0,1,...,nshiftngroup?nshift?1and NCS is given by Tables 5.7.2-2 and 5.7.2-3 for preamble formats 0-3 and 4, respectively. The parameter High-speed-flag provided by higher layers determines if unrestricted set or restricted set shall be used. The variable du is the cyclic shift corresponding to a Doppler shift of magnitude 1TSEQ and is given by
?1?0?u?1modNZC?NZC2?umodNZC du???1?N?umodNotherwiseZC?ZCThe parameters for restricted sets of cyclic shifts depend on du. ForNCS?du?NZC3, the parameters are given by
