Let G be the group of rational points of a split connected reductive group over a non-Archimedean local field of residue characteristic p, says Kohlhaase, and let I be a pro-p Iwahori subgroup of G and let R be a commutative quasi-Frobenius ring. So, if H = R[I\G/I] denotes the pro-p Iwahori-Hecke algebra of G over R, he clarifies the relation between the category of H-modules and the category of G-equivariant coefficient systems on the semisimple Bruhat-Tits building of G.
