Zusammenfassung:Various embodiments herein provide techniques for user equipment (UE) behavior and delay requirements in case of spatial relation information change for an uplink signal, such as a sounding reference signal (SRS), a physical uplink control channel (PUCCH), and/or a physical uplink shared channel (PUSCH). In one example, the UE determines a delay time period from receipt of a message that indicates spatial relation information for uplink transmission. The delay time period includes a decoding time period and a UE processing and preparation time period. The UE transmits an uplink signal using the indicated spatial relation information after expiration of the delay time period.
