Method and apparatus for handling a cell change

摘要

Example embodiments presented herein are directed towards a user equipment, and corresponding methods therein, for handling a cell change from a first cell to a second cell in a wireless communications network. Some example embodiments may also be directed towards the user equipment altering a duration of a measurement time over which at least one measurement is performed, and altering a measurement bandwidth of the at least one measurement. The alterations may be performed based on associated bandwidths of the first and second cells. Other example embodiments may be directed towards a network node, and corresponding method therein, for sending, to the user equipment, a notification of a cell change and information associated with the cell change. Example embodiments may further comprise the network node receiving measurement data of at least one measurement performed over an altered measurement bandwidth and an altered duration of measurement time, where the alterations are based on the information associated with the cell change.

主权项

1. A method in a user equipment for handling a cell change, the user equipment being comprised in a wireless communications network, the method comprising:
performing at least one measurement; wherein the at least one measurement is a Reference Signal Time Difference, RSTD, measurement; receiving from a network node, a notification of, and information associated with, the cell change from a first cell to a second cell; performing the cell change during the at least one measurement; altering a duration of a measurement time over which the at least one measurement is performed; altering a measurement bandwidth of the at least one measurement, wherein the altering is based on associated bandwidths of the first and second cells; and completing the at least one measurement based on the altered duration of measurement time and the altered measurement bandwidth.
