A method for wireless communication, comprising: identifying a set of shortened transmission time intervals, sTTIs , for uplink transmissions of a first wireless service, the set of sTTIs located within subframe time boundaries of a subframe of a second wireless service; identifying two or more sTTIs within the set of sTTIs for transmission of sounding reference signal, SRS, transmissions within the subframe time boundaries; and transmitting one or more SRS transmissions in at least one of the two or more sTTIs , the method further comprising identifying a first subset of the set of sTTIs that each span two orthogonal frequency division multiplexing, OFDM, symbols and a second subset of the set of sTTIs that each span three OFDM symbols; and configuring two or more sTTIs of the second subset for the one or more SRS transmissions, wherein identifying the second subset comprises: identifying a first three-symbol sTTI as an initial sTTI of a first slot within the subframe time boundaries; identifying a second three-symbol sTTI as a final sTTI of a second slot within the subframe time boundaries; and identifying a first SRS symbol (645-a) within the first three-symbol sTTI for a first SRS transmission and a second SRS symbol (645-b) within the second three-symbol sTTI for a second SRS transmission, wherein the second SRS symbol (645-b) of a first subframe is adjacent to the first SRS symbol of a subsequent subframe. identifying a set of shortened transmission time intervals, sTTIs , for uplink transmissions of a first wireless service, the set of sTTIs located within subframe time boundaries of a subframe of a second wireless service; identifying two or more sTTIs within the set of sTTIs for transmission of sounding reference signal, SRS, transmissions within the subframe time boundaries; and transmitting one or more SRS transmissions in at least one of the two or more sTTIs , the method further comprising identifying a first subset of the set of sTTIs that each span two orthogonal frequency division multiplexing, OFDM, symbols and a second subset of the set of sTTIs that each span three OFDM symbols; and configuring two or more sTTIs of the second subset for the one or more SRS transmissions, wherein identifying the second subset comprises: identifying a first three-symbol sTTI as an initial sTTI of a first slot within the subframe time boundaries; identifying a second three-symbol sTTI as a final sTTI of a second slot within the subframe time boundaries; and identifying a first SRS symbol (645-a) within the first three-symbol sTTI for a first SRS transmission and a second SRS symbol (645-b) within the second three-symbol sTTI for a second SRS transmission, wherein the second SRS symbol (645-b) of a first subframe is adjacent to the first SRS symbol of a subsequent subframe. identifying a first three-symbol sTTI as an initial sTTI of a first slot within the subframe time boundaries; identifying a second three-symbol sTTI as a final sTTI of a second slot within the subframe time boundaries; and identifying a first SRS symbol (645-a) within the first three-symbol sTTI for a first SRS transmission and a second SRS symbol (645-b) within the second three-symbol sTTI for a second SRS transmission, wherein the second SRS symbol (645-b) of a first subframe is adjacent to the first SRS symbol of a subsequent subframe. <EOS>
