Title:
DETERMINING TRANSMISSION PREPARATION TIME FOR WIRELESS COMMUNICATION ON AT LEAST ONE CARRIER
Document Type and Number:
WIPO Patent Application WO/2021/217322
Kind Code:
A1
Abstract:
A base station (BS) may determine (e.g., estimate) a preparation time for at least one uplink (UL) transmission by a user equipment (UE) on at least one radio frequency (RF) carrier. The BS may determine the preparation time so that the BS will send a grant for the at least one transmission to the UE a sufficient amount of time (based on the estimated preparation time) before the at least one transmission is scheduled to occur. In some examples, the BS may select the sub-carrier spacing (SCS) index from the SCS indexes for a first RF carrier and a second RF carrier that provides a longer preparation time. In this way, the determined preparation time will be long enough to enable the UE to conduct the at least one UL transmission on a selected one of the RF carriers or on both RF carriers.
