Parameter | Definition |
|---|---|
\(N_\text {S} \in \{1,2,4,8\}\) | Number of different base sequences used in the network. In this work, the maximum number of different base sequences is limited to eight |
\(n \in \{0,1, \ldots , N_{\text {S}}-1 \}\) | Base sequence index |
\(M_{\text {C}} \in \{10, 20, 40, 80\}\) | Number of gNBs transmitting a copy of the same base sequence |
\(M_{\text {gNB}} = N_{\text {S}} M_\text {C}\) | Total number of gNBs transmitting a RIM-RS and the number of sequences arriving to the receiver within a delay window |
\(M_{\text {G}} = 10\) | Number of gNBs per group. In this work, a constant value of 10 is assumed |
\(m \in \{ 0,1, \ldots , M_{\text {G}}-1\}\) | gNB index within a gNB group |
\(G = M_{\text {gNB}}/M_{\text {G}}\) | Number of aggressor gNB groups |
\(g \in \{0,1, \ldots , G-1 \}\) | Aggressor gNB group index |
\(K = 600\) | Total number of resource elements (REs) allocated for the base sequence |
\(k \in \{ 0,1,\ldots , K-1 \}\) | Frequency domain RE index |
S | Length of the used base sequence |
\(s \in \{0,1,\ldots , S-1 \}\) | Sample index within the used base sequence |
\(c \in \{0,1,2,3\}\) | Cyclic shift index used for transmitting a specific base sequence. Maximum number of cyclic shifts depends on the used frequency domain comb-pattern. |
\(N_{\text {rep}} \in \{1, 2, 4\}\) | Number of time domain repetitions with comb-1, comb-2, and comb-4 frequency patterns. |
