摘要： Systems and methods related to a synchronization signal (18) particularly well suited for wireless devices (22) in an extended coverage area (16) of a cell (14) of a cellular communications network (10) are disclosed. In one embodiment, a base station (12) transmits a synchronization signal (18) including multiple repetitions of a basic synchronization block during a coherence time of a downlink channel over which the synchronization signal (18) is transmitted. The multiple repetitions of the basic synchronization block during the coherence time enable coherent combining during detection of the synchronization signal (18) at wireless devices (22) located in the cellular communications network (10). This coherent combining enables, for example, wireless devices (22) located in an extended coverage area (16) of a cell (14) served by the base station (12) to synchronize to the cell (14) using a shorter synchronization signal (18) than that which would be required if only non-coherent combining were used.

摘要： One aspect of the teachings herein involves the advantageous use of learned statistical information to improve inter-cell interference coordination, "ICIC". A network (20) uses historical signal quality measurements collected over time for wireless communication devices (36) operating within its coverage areas to identify those geographical areas where devices (36) generally experience significant levels of patterned interference. In an example case, the network (20) develops a "map" of the geographical areas that are affected by the transmission patterns of neighboring nodes (26, 30), and it applies the map to ICIC operations, wherein the serving nodes associated with the affected areas incorporate knowledge of the interfering transmission patterns into the ongoing scheduling of devices (36) operating in the affected areas.

摘要： In a cellular communication network, a method of dynamic mobility management in which a base station employing cell-breathing or other Similar energy- efficiency mechanism notifies User Equipments, UEs in its cell, either via broadcasting or with direct over-the-air signaling, that such a mechanism is utilized within the cell. The base station may also notify neighbor base stations of its use of cell-breathing. The neighbor base stations disseminate this information to UEs within their own cells, and consider this information when deciding whether to hand over a UE to a base station that is capable of performing cell-breaming. The base station may also inform UEs in the cell and/or neighbor base stations when it is preparing to reduce transmission power. UEs store information regarding which base stations use cell-breathing, and consider this information when perforating cell reselections.

In one embodiment, a network node in the cellular communications network determines whether a wireless device is within LOS of a base station. In order do so, the network node compares a Ricean factor of a wireless communications channel between the base station and the wireless device and a predetermined Ricean factor threshold for LOS detection. In addition, the network node compares a Root Mean Squared Error (RMSE) between a Rayleigh probability density function and samples of received signal strength for radio signals transmitted between the base station and the wireless device and a predetermined RMSE threshold for LOS detection. The network node then determines whether the wireless device is within LOS of the base station based on results of the comparisons.
