摘要： The embodiments disclosed relates to a method and a network node that determines a time period between a first handover and a second handover of a user equipment. The first handover is to or from a first cell and the second handover is to or from a second cell. The network node sets a threshold value based on a difference in cell quality between the first cell and the second cell. The difference in cell quality is associated with the first or second handover. The network node then determines the type of handover, of at least one of the first and second handover, based on the time period and threshold value.

摘要： Frequency-selective phase shifts are applied to signals transmitted from multiple transmission points involved in a coordinated (joint) transmission to a given UE. An eNodeB or other network node controlling the joint transmission artificially induces frequency selectivity between signals received by the UE in joint transmission from different transmission points, so as to ensure an even balance between constructive and destructive combination over frequency. By applying frequency-selective phase shifts (e.g., pseudo-random phase shifts) to the different transmission points that perform joint transmission, the signals from the different transmission points are forced to combine at the UE in a non-coherent manner. As a result, uncertainty in how the signals combine is drastically reduced, since it can be expected that the signals will always combine incoherently. The reduced uncertainty translates to reduced back-off offset in the link adaptation, and thus in an increased throughput.
摘要翻译：频率选择性相移被应用于从涉及协调（联合）传输到给定UE的多个传输点发送的信号。控制联合传输的eNodeB或其他网络节点在不同传输点的联合传输中人为地诱导由UE接收的信号之间的频率选择性，以便确保在频率上的建设性和破坏性组合之间的均衡。通过对执行联合传输的不同传输点应用频率选择性相移（例如，伪随机相移），来自不同传输点的信号被强制以不相干的方式在UE处组合。结果，信号组合的不确定性大大降低，因为可以预期信号将总是不连贯地组合。减少的不确定性转化为链路适配中的减小偏移，并且因此增加的吞吐量。

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.
