Query: A Reliable Uplink Control Channel Design with Complementary Sequences   In this study, we propose two schemes for uplink control channels based on
non-contiguous complementary sequences (CSs) where the peak-to-average-power
ratio (PAPR) of the resulting orthogonal frequency division multiplexing (OFDM)
signal is always less than or equal to 3 dB. To obtain the proposed schemes, we
extend Golay's concatenation and interleaving methods by considering extra
upsampling and shifting parameters. The proposed schemes enable a flexible
non-contiguous resource allocation in frequency, e.g., an arbitrary number of
null symbols between the occupied resource blocks (RBs). The first scheme
separates the PAPR minimization and the inter-cell interference minimization
problems. While the former is solved by spreading the sequences in a Golay
complementary pair (GCP) with the sequences in another GCP, the latter is
managed by designing a set of GCPs with low cross-correlation. The second
scheme generates reference symbols (RSs) and data symbols on each RB as parts
of an encoded CS. Therefore, it enables coherent detection at the receiver
side. The numerical results show that the proposed schemes offer significantly
improved PAPR and cubic metric (CM) results in case of non-contiguous resource
allocation as compared to the sequences defined in 3GPP New Radio (NR) and
Zadoff-Chu (ZC) sequences.
