A method of wireless communication performed by a user equipment, UE, comprising: receiving, from a serving base station, a medium access control control element, MAC-CE, indicating activation or deactivation of a semi-persistent, SP, sounding-reference-signal-for-positioning, SRS-for-positioning, wherein a reserved bit in the MAC-CE or a logical channel identifier, LCID, of a MAC subheader of the MAC-CE indicates the activation or deactivation of the SP SRS-for-positioning; and transmitting the SP SRS-for-positioning on one or more SRS resources configured for the UE, the SP SRS-for-positioning having transmission parameters adopted from a spatial relation reference signal for the SP SRS-for-positioning, wherein the MAC-CE includes at least one three-bit field having a value that indicates any particular one of five possible types of the spatial relation reference signal from which transmission parameters are adopted for the transmission of the SP SRS-for-positioning, the five possible types including a first possible type, a second possible type, a third possible type, a fourth possible type and a fifth possible type, wherein the first possible type of the spatial relation reference signal from which transmission parameters are adopted is an SRS-for-communication resource, wherein the second possible type of the spatial relation reference signal from which transmission parameters are adopted is a synchronization signal block, SSB, wherein the third possible type of the spatial relation reference signal from which transmission parameters are adopted is a channel state information reference signal, CSI-RS, resource, wherein the fourth possible type of the spatial relation reference signal from which transmission parameters are adopted is an SRS-for-positioning resource, wherein the fifth possible type of the spatial relation reference signal from which transmission parameters are adopted is a downlink positioning reference signal, DL PRS, resource, wherein the MAC-CE further includes at least one spatial relation information field indicating an identifier, ID, of the spatial relation reference signal from which transmission parameters are adopted for the transmission of the SP SRS-for-positioning. receiving, from a serving base station, a medium access control control element, MAC-CE, indicating activation or deactivation of a semi-persistent, SP, sounding-reference-signal-for-positioning, SRS-for-positioning, wherein a reserved bit in the MAC-CE or a logical channel identifier, LCID, of a MAC subheader of the MAC-CE indicates the activation or deactivation of the SP SRS-for-positioning; and transmitting the SP SRS-for-positioning on one or more SRS resources configured for the UE, the SP SRS-for-positioning having transmission parameters adopted from a spatial relation reference signal for the SP SRS-for-positioning, wherein the MAC-CE includes at least one three-bit field having a value that indicates any particular one of five possible types of the spatial relation reference signal from which transmission parameters are adopted for the transmission of the SP SRS-for-positioning, the five possible types including a first possible type, a second possible type, a third possible type, a fourth possible type and a fifth possible type, wherein the first possible type of the spatial relation reference signal from which transmission parameters are adopted is an SRS-for-communication resource, wherein the second possible type of the spatial relation reference signal from which transmission parameters are adopted is a synchronization signal block, SSB, wherein the third possible type of the spatial relation reference signal from which transmission parameters are adopted is a channel state information reference signal, CSI-RS, resource, wherein the fourth possible type of the spatial relation reference signal from which transmission parameters are adopted is an SRS-for-positioning resource, wherein the fifth possible type of the spatial relation reference signal from which transmission parameters are adopted is a downlink positioning reference signal, DL PRS, resource, wherein the MAC-CE further includes at least one spatial relation information field indicating an identifier, ID, of the spatial relation reference signal from which transmission parameters are adopted for the transmission of the SP SRS-for-positioning.
