摘要： The invention discloses a timing synchronization method in a User Equipment (UE) which is served in a first cell of a first synchronous communication network and also located in a second cell of a second synchronous communication network. The method comprises receiving a message from a communication node of the first network, the message including clock offsets of the first cell and the second cell or timing difference there between, and calculating downlink synchronization of the second cell from downlink synchronization of the first cell and the clock offsets/timing difference.

摘要： In one aspect, the present invention comprises an apparatus and method for improving energy saving procedures in a wireless communication network, wherein one or more cells in the network are selectively inactivated for energy savings and reactivated as needed. More particularly, the present invention provides improved control for transitioning a cell to or from a power savings mode, including dynamic, adjustable power control and handover parameter control, based on the involved cells exchanging status and/or control information. The dynamic control results in gradual rather than abrupt changes to cell coverage area, as a cell is transitioned to or from the power savings mode.

摘要： A radio base station and a method therein are provided for allocating measurement gaps within a MGRP to UEs currently being served by the base station, wherein consideration is taken to the impact a measurement gap has on the HARQ processes. A plurality of possible measurement gaps are identified within the MGRP with regards to their starting point and duration in time within the MGRP. A number of HARQ processes that would be affected due to the identified measurement gaps with regards to a starting point in time of the identified measurement gaps during the MGRP are determined for the identified measurement gaps. The identified measurement gaps are ranked depending on the number of HARQ processes which would be affected during the MGRP and the identified measurement gaps are allocated to the UEs based on the ranking.
