摘要
According to a first aspect there is provided a method, performed at a User Equipment, 'UE', of a wireless communications network, the method comprising: detecting that a downlink transmission timing has changed by an amount of time; determining that a time alignment timer, 'TAT', is not running; and while the TAT is not running, adjusting a timing advance for uplink transmissions based on the amount of time that the downlink transmission timing has changed, wherein the timing advance for uplink transmissions was stored in memory at expiration of the TAT. According to further aspects there are provided a user equipment to perform such a method and a computer readable medium storing instructions to cause a processor to perform such a method.
