Abstract
A method for enhanced autonomous uplink timing adjustment includes determining that a user equipment (UE) is traveling above a predetermined velocity. In response to the determination that the UE is traveling above the predetermined velocity, a maximum aggregate adjustment rate to an uplink timing for the UE and a maximum amount of a magnitude of a timing change to the uplink timing for the UE are determined. The uplink timing for the UE is adjusted based on the maximum aggregate adjustment rate and the maximum amount of the magnitude of the timing change.
Claims21
A method, comprising:
- receiving an indication of a high-speed configuration for a device;
- determining a time adjustment to an uplink timing for the device based at least in part on the indication of the high-speed configuration for the device;
- and
- transmitting an uplink transmission by the device based at least in part on the determined time adjustment to the uplink timing.
A device, comprising:
- a transceiver;
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
- receiving an indication of a high-speed configuration for a device;
- determining a time adjustment to an uplink timing for the device based at least in part on the indication of the high-speed configuration for the device;
- and
- transmitting, by the transceiver, an uplink transmission by the device based at least in part on the determined time adjustment to the uplink timing.
An access node (AN), comprising:
- a transceiver;
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
- transmitting, by the transceiver and to a device, an indication of a high-speed configuration for the device, wherein the indication causes the device to determine a time adjustment to an uplink timing, the time adjustment for the device based at least in part on the indication of the high-speed configuration for the device
- receiving, by the transceiver, an uplink transmission from the device, wherein the uplink transmission is transmitted based on the uplink timing.
