METHOD AND DEVICE FOR GENERATION OF A ZC SEQUENCE OF A RANDOM ACCESS CHANNEL Russian patent published in 2018 - IPC H04W74/08 

FIELD: electrical engineering.

SUBSTANCE: invention relates to a base station, a user equipment (UE), and a method for generating a ZC sequence of a random access channel. Method for generating a ZC sequence of a random access channel comprises the following steps: UE selects a sequence number ν of shift in the range from 0 to , where ν is a positive integer, is the number of candidates for successive UE shifts in one group, represents the number of groups and is the number of candidates for consecutive UE shifts within the last length, which is insufficient for one group; are obtained using the UE, value of C_ν cyclic shift in accordance with the sequence number ν and are generated using the UE, random access sequence ZC in accordance with the value of C_ν cyclic shift using the above expressions.

EFFECT: technical result is to ensure that interference between a plurality of random access sequences UE caused by a Doppler frequency shift is avoided.
