Abstract
Technologies and techniques are disclosed for managing timing advance (TA) validation of configured grant small data transmission (CG-SDT). A scheduling entity may receive downlink signal quality measurements for downlink beams from a scheduled entity, as well as a CG-SDT configuration request. The scheduling entity may transmit a CG-SDT configuration to the UE in response to receiving the CG-SDT configuration request, where the CG-SDT configuration includes a timing advance (TA) validation criteria based on downlink signal quality measurements meeting configured thresholds.
Claims22
A scheduling entity within a wireless communication network, comprising:
- a one or more memories;
- and
- a one or more processors coupled to the one or more memories, wherein the one or more processors are configured to:
- transmit a configured grant small data transmission (CG-SDT) configuration to a user equipment (UE), the CG-SDT configuration comprising timing advance (TA) validation criteria indicating that TA validation prior to a CG-SDT transmission be based on at least one downlink signal quality measurement meeting at least one threshold;
- transmit, on a periodic schedule together with one of a wake-up signal (WUS) or a paging signal within a discontinuous reception (DRX) time period, one or more downlink reference signals for TA validation;
- and
- receive a communication from the UE based on the CG-SDT configuration.
A method of wireless communication of a scheduling entity in a wireless communication network, the method comprising:
- transmitting a configured grant small data transmission (CG-SDT) configuration to a user equipment (UE), the CG-SDT configuration comprising timing advance (TA) validation criteria based on at least one downlink signal quality measurement meeting at least one threshold;
- transmit, on a periodic schedule together with one of a wake-up signal (WUS) or a paging signal within a discontinuous reception (DRX) time period, one or more downlink reference signals for TA validation of a CG-SDT transmission
- receiving a communication from the UE based on the CG-SDT configuration.
