An apparatus for wireless communication by a user equipment, UE , comprising: means for determining a first sounding reference signal, SRS, frequency hopping pattern for transmitting one or more SRSs; means for determining an antenna switch will occur during transmission of the one or more SRSs; means for determining a second SRS frequency hopping pattern for transmitting the one or more SRSs, wherein determining the second SRS frequency hopping pattern comprises using the first SRS frequency hopping pattern to generate the second SRS frequency hopping pattern based on the determined antenna switch and by repeating an order of subbands in the first SRS frequency hopping pattern at least for a subset of antenna indices; and means for transmitting a first set of SRSs of the one or more SRSs according to the first SRS frequency hopping pattern and transmit a second set of SRSs of the one or more SRSs according to the second SRS frequency hopping pattern; characterized in that at least one of the first SRS frequency hopping pattern or the second SRS frequency hopping pattern is determined according to: N = RN AS N FH + (N AS - 1 )G AS + (N FH - 1 )N AS G FH + (N AS - 1)(1 - G AS )G FH , where N is a total duration associated with the one or more SRSs, R is a repetition factor associated with the one or more SRSs, N AS is a number of antenna switches associated with the one or more SRSs, N FH is a number of frequency hops with a same antenna or antenna pair associated with the one or more SRSs, G AS ∈ is a guard symbol configuration value for antenna switching, and G FH ∈ is a guard symbol configuration value for frequency hopping of the one or more SRSs. means for determining a first sounding reference signal, SRS, frequency hopping pattern for transmitting one or more SRSs; means for determining an antenna switch will occur during transmission of the one or more SRSs; means for determining a second SRS frequency hopping pattern for transmitting the one or more SRSs, wherein determining the second SRS frequency hopping pattern comprises using the first SRS frequency hopping pattern to generate the second SRS frequency hopping pattern based on the determined antenna switch and by repeating an order of subbands in the first SRS frequency hopping pattern at least for a subset of antenna indices; and means for transmitting a first set of SRSs of the one or more SRSs according to the first SRS frequency hopping pattern and transmit a second set of SRSs of the one or more SRSs according to the second SRS frequency hopping pattern; characterized in that at least one of the first SRS frequency hopping pattern or the second SRS frequency hopping pattern is determined according to: N = RN AS N FH + (N AS - 1 )G AS + (N FH - 1 )N AS G FH + (N AS - 1)(1 - G AS )G FH , where N is a total duration associated with the one or more SRSs, R is a repetition factor associated with the one or more SRSs, N AS is a number of antenna switches associated with the one or more SRSs, N FH is a number of frequency hops with a same antenna or antenna pair associated with the one or more SRSs, G AS ∈ is a guard symbol configuration value for antenna switching, and G FH ∈ is a guard symbol configuration value for frequency hopping of the one or more SRSs. <EOS>
