    • Uplink buffer occupancy(304), and a link imbalance between a serving and a neighbour cell operating in the same frequency and the same radio access technology, are determined for a user equipment UE. Based at least on those,the UE is controlled to transition directly from an idle state with the serving cell to a connected state with the neighbour cell (308,310B). In one embodiment the UE checks its own buffer occupancy, link imbalance and downlink channel quality against thresholds to decide whether to transition directly. In another embodiment the UE sends to the serving cell at least its buffer occupancy and link imbalance, and the serving cell sends to the UE a redirect message that identifies the neighbour cell as a target cell for the direct transition. The neighbour cell may be a small cell operating at a lower transmit power than the (macro) serving cell.
    • 对于用户设备UE确定上行链路缓冲器占用(304),并且在相同频率下运行的服务和相邻小区之间的链路不平衡以及相同的无线接入技术。 至少基于这些,UE被控制以从服务小区的空闲状态直接转换到与相邻小区(308,310B)的连接状态。 在一个实施例中,UE根据阈值检查其自身的缓冲器占用,链路不平衡和下行链路信道质量,以决定是否直接转换。 在另一个实施例中,UE至少向服务小区发送其缓冲器占用和链路不平衡,并且服务小区向UE发送重定向消息,其将相邻小区标识为用于直接转换的目标小区。 相邻小区可以是以比(宏)服务小区更低的发射功率工作的小小区。

    • A method, apparatus and software related product avoid UL interference in a victim LPN (20) such as femtocell using a discontinuous reception (DRX) by the LPN (20) coordinated with the UL discontinuous transmission (DTX) of UEs (22) to the LPN (20) and to one or more HPNs (27,28) such as NBs (or Home NB), e.g. in HSPA systems. The victim LPN (20) may start DRX having ON and OFF periods. Then the LPN (20) sends information about DRX to its UEs (LUEs 22) communicating with the LPN (20), and to one or more network elements such as aggressor HPNs' RNCs. The network element(s) are adapted to identify and configure aggressor UEs (HUEs 24,26) communicating with one or more HPNs (27,28) of the network for coordinating ON and OFF periods of the discontinuous reception by the LPN (20) with transmissions of the LUEs (22) and the HUEs (24,26) to avoid interference during the OFF periods of the DRX in the LPN (20).

    • A network sends (302) to a user equipment UE downlink signalling indicating at least one frequency which is subject to special handling. In response,the UE measures and reports neighbour cells operating on any of that/those frequencies without regard to a threshold signal strength of a serving cell which is configured for reporting neighbour cells(304). In more specific examples, if the neighbour cells operating on any of that/those frequencies is considered a first set of neighbour cells, then the network also sends a second set of neighbour cells in other downlink signalling(306). Measuring and reporting on the first set of neighbour cells is less frequent than for the second set of neighbour cells, when measurements of the second set is required(306). Measuring and reporting on the second set is dependent on measured signal strength of a serving cell being greater than the configured threshold signal strength of the serving cell(308).
    • 网络向用户设备UE发送(302)下行信令,指示经过特殊处理的至少一个频率。 作为响应,UE测量并报告在该/那些频率中的任一个上操作的相邻小区,而不考虑配置用于报告相邻小区的服务小区的阈值信号强度(304)。 在更具体的例子中,如果在任何这些/那些频率上工作的相邻小区被认为是第一组相邻小区,则网络还在其他下行链路信令中发送第二组相邻小区(306)。 当需要测量第二组时,第一组相邻小区的测量和报告比第二组相邻小区频繁(306)。 第二组的测量和报告取决于服务小区的测量信号强度大于所配置的服务小区(308)的阈值信号强度。
