English to Polish Tech/Engineering Telecom(munications) Metody dostępu do bezprzewodowego systemu komunikacji

Mieliśmy już "waveform" i w owym kontekście od Pana Crannmera uzyskałem podpowiedź "przebieg sygnału pomiaru odległości". Teraz temat powraca w innym kontekście. Oczywiście mógłbym po prostu dodać "access" i powstałby chyba potworek w stylu 1) "przebieg sygnału pomiaru odległości dostępu" (?!) 2) "dostęp do przebiegu sygnału pomiaru odległości" (?!), ale pewnie sprawa nie jest aż tak prosta, jak to zwykle bywa przy tak skomplikowanej (i jak twierdzą fachowcy) dopiero rodzącej się terminologii. Podaję kontekst i jak zwykle błagam o pomoc:

Referring to FIG. 6, a block diagram shows the division of ranging opportunities in frequency, time, and code
domains, in accordance with some embodiments of the present invention. Each random access signal is generated based on a ranging sequence (interchangeable with "access sequence" and "ranging code" and "access code") that is randomly chosen from a code group 601 allocated to the sector (the code group size is denoted herein as Nc, an integer). The access sequences used in a code group and the allocation of code groups to different sectors are specified later. The ranging sequence may be used to generate an access signal by directly modulating the contiguous sub-carriers in a frequency block (sub-band) that is randomly chosen among Nb1 sub-bands 602, wherein Nb1 is an integer including the value "1" known to both BS and SS. Nb1 may be determined based on the system bandwidth and be made known to the BS and the SS. The time-domain access signal is generated by performing an IFFT on the ranging sequence after modulating the chosen sub-band. Before a CP is inserted in front of the access signal to form a complete access waveform, the access signal may be cyclically (circularly) shifted in time domain, where the shift is chosen randomly among Nsh allowed values 603 that are known to the BS and SS, wherein Nsh is an integer. Lastly, a CP is added to form the final ranging waveform where the length of the CP is that of the extended CP for initial ranging and for other ranging, either the extended CP or the regular CP depending on the transmission point (discussed above). The duration of the waveform corresponds to the duration of one OFDM symbol in the extended ranging interval, in embodiments such as those described with reference to FIG. 3 and FIG. 5 In embodiments such as those described with reference to FIG. 5, the ranging sequence may be used to generate an access waveform by appending data symbols to the ranging sequence and directly modulating the contiguous sub-carriers in the frequency block (sub-band) that is randomly chosen, using terms of the appended ranging sequence.
