On the other hand, in the case of DCI scheduling/indicating multiple PUSCH transmission resources over a plurality of slots as described above (for convenience, such DCI is referred to as “multi-slot DCI”), if a (DCI-to-PUSCH) slot offset indicated by the DCI for a (first) PUSCH transmission time is defined as K, the transmission time (slot) of a (SRS) resource set indicated by an a-SRS request field in the corresponding DCI, that is, a DCI-to-SRS slot offset is determined as the maximum value of K and K_s, i.e., max(K, K_s) or {K+K_s}, which is the sum of K and K_s. Alternatively, if the total number of slots in which PUSCH transmissions (resources) are scheduled/indicated is defined as N_s, the DCI-to-SRS slot offset may be determined as {K+K_s mod N_s}, {min (K+K_s, K+N_s?1)}, or {min (max (K, K_s), K+N_s?1)}.
In addition, if an SRS resource (or SRS resource set) where transmission is indicated by the multi-slot DCI overlaps in time with the entirety of a specific PUSCH resource (or a DMRS symbol of the corresponding PUSCH) scheduled by the corresponding multi-slot DCI, the corresponding PUSCH transmission may be dropped. Additionally, if the SRS resource (or SRS resource set) indicated/scheduled by the multi-slot DCI overlaps with a part of the specific PUSCH resource (not including the DMRS symbol or including the DMRS symbol), the corresponding PUSCH (resource) may be transmitted after performing rate-matching or puncturing on overlapping symbols.
