There are 504 unique physical layer cell identities The physical layer cell identities are grouped into 168 unique physical layer cell identity groups each group containing three unique identities The grouping is such that each physical layer cell identity is part of one and only one physical layer cell identity group A physical layer cell identity PCI 3SecondarySynchronisationSignal PrimarySynchronisationSignal The SecondarySynchronisationSignal has a range of 0 to 167 representing the physical layer cell identity group The PrimarySynchronisationSignal asa range of 0 to 2 representing the physical layer identity within the physical layer cell identity group The sequence for the SecondarySynchronisationSignal SSS signal is generated as follows m0 m mod 31 m1 m0 INT m 31 1 mod 31 m Sj q q 1 2 q INT Sj q q 1 2 30 q INT Sj 30 Studies have shown that PCIs of adjacent cells that meet the following criteria will have problems with performance long synchronisation times high interference The same SecondarySynchronisationSignal value The same m0 value The same m1 value This macro calculates all the PCIs that meet the above criteria i e all the PCIs that adjacent cells should not have Instructions 1 On the next tab input the PCI value you wish to use for your cell in the red box in the top left corner 2 Click the Calculate value Explanation of results The grey box below the input box shows the PrimarySynchronisationSignal PSS SecondarySynchronisationSignal SSS m0 and m1 values for the PCI The blue columns show the PCIs that should not be used for adjacent cells References 3GPP TS 36 211 v 9 0 0 Maria Thiesen Considerations for PCI planning knowledge object PCI99 PSS0 SSS33 q 1 q1 m 34 m03 m15 Calculate PCIs not allowed in adjacent cells PCIs with same PSSPCIs with same m0PCIs with same m1 96912 931013 901114 87100100 84101101 81186183 78187184 75188185 72270264 69271265 66272266 63351342 60352343 57353344 54429 51430 48431 45 42 39 36 33 30 27 24 21 18 15 12 9 6 3 102 105 108 111 114 117 120 123 126 129 132 135 138 141 144 147 150 153 156 159 162 165 168 171 174 177 180 183 186 189 192 195 198 201 204 207 210 213 216 219 222 225 228 231 234 237 240 243 246 249 252 255 258 261 264 267 270 273 276 279 282 285 288 291 294 297 300 303 306 309 312 315 318 321 324 327 330 333 336 339 342 345 348 351 354 357 360 363 366 369 372 375 378 381 384 387 390 393 396 399 402 405 4
