Abstract: Aspects of system information block (SIB) management during wireless communication include assigning a cell controlled by a network entity to a cell group based on at least one interference parameter of the cell, wherein the cell group is one of a plurality of cell groups into which each cell in the wireless network is assigned based on a respective interference parameter of each cell. The SIB management further includes identifying, within a subframe, one or more SIB resource blocks (RBs) in which a SIB transmission is scheduled for other cells in the cell group. In addition, the SIB management includes halting, at the network entity, one or more non-SIB RB transmissions of the cell in the identified one or more SIB RBs in the subframe in which the SIB transmission is scheduled for the other cells in the cell group.

Abstract: Systems and methods for selecting an operating channel for a small cell are described. A determination can be made to select a different operating channel at a small cell based at least in part on at least one of a downlink quality metric or an uplink quality metric. One or more connected mode user equipments (UE) served by the small cell can be caused to handover to one or more neighboring cells, and one or more parameters configured to one or more idle mode UEs camped on the small cell can be modified to cause the one or more idle mode UEs to reselect to the one or more neighboring cells. The operating channel of the small cell can be switched to the different operating channel at least when the one or more connected mode UEs are handed over to the one or more neighboring cells.

Abstract: Methods, systems, and devices are described for managing a handover of a UE based on consideration of both the uplink and the downlink channel conditions. A handover of a user equipment from a serving base station to a target base station may be held over, prevented or inhibited even if the downlink channel measurement events are triggered and reported based on consideration of the uplink and the downlink metrics. Such determination may also be based on weight factors associated with the uplink and the downlink metrics. The weight factors may communicate to the base station a relative value of the uplink and the downlink transmission for a user equipment. In other examples, a handover of the user equipment may be either initiated or held over based on a calculation of a loading delta that indicates an overall gain or loss that may be realized between the serving base station and the target base station.

Abstract translation: 描述了用于基于上行链路和下行链路信道条件的考虑来管理UE的切换的方法，系统和设备。 即使下行链路信道测量事件被触发并且基于上行链路和下行链路度量的考虑而被报告，用户设备从服务基站到目标基站的切换也可以被保持，阻止或禁止。 这种确定也可以基于与上行链路和下行链路度量相关联的加权因子。 加权因子可以向基站通信用户设备的上行链路和下行链路传输的相对值。 在其他示例中，可以基于指示可以在服务基站和目标基站之间实现的总体增益或丢失的负载增量的计算来启动或保持用户设备的切换。

Abstract: Methods, systems, and devices are described for dynamically adjusting a ZeroCorrelationZoneConfig (Ncs) parameter of a base station. An initial Ncs parameter is set for the base station. A determination is made as to whether a count of timing synchronization failures between a mobile device and the base station exceeds a threshold. A determination is also made as to whether the timing synchronization failures correspond to a predetermined range of timing advanced (TA) estimated values. Upon determining that the count of timing synchronization failures exceeds the threshold and that the failures correspond to the predetermined range of TA estimated values, the initial Ncs parameter is dynamically adjusted.
