Patent ID: 11968640
Assignee: HUAWEI TECHNOLOGIES CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 15:
16. The timing advance update method according to claim 15, wherein that the terminal obtains a transmission delay TA offset based on the round-trip transmission delay change rate and a unidirectional transmission delay of the current location is performed according to the following formula:

ΔTAtrans=T′α×ttrans, wherein

ΔTAtrans represents the transmission delay TA offset, and ttrans represents the unidirectional transmission delay of the current location, and wherein
that the terminal obtains a TA offset based on the round-trip transmission delay change rate, a unidirectional transmission delay of the current location, and current TA update period duration is performed according to the following formula:

ΔTA=T′α×(ttrans+tupdate), where

ΔTA represents the TA offset, and tupdate represents the current TA update period duration.
