摘要： Systems, apparatuses, and methods for a handover procedure in heterogeneous networks are provided. In particular, an intermediate handover (IHO) is introduced. Certain aspects of the disclosure involve, a method, performed at a serving base station of a wireless communications network, where the serving base station serves a user equipment (UE). The method includes receiving a downlink (DL) signal quality indicator from the UE; and determining, from the signal quality indicator, whether a condition for an intermediate handover (IHO) state is satisfied. If the condition for the intermediate handover state is satisfied, the serving base station can initiate the intermediate handover state.
摘要翻译：提供了用于异构网络中的切换过程的系统，装置和方法。特别地，引入了中间切换（IHO）。本公开的某些方面涉及在无线通信网络的服务基站执行的方法，其中服务基站服务于用户设备（UE）。该方法包括从UE接收下行链路（DL）信号质量指示符; 以及从所述信号质量指示符确定是否满足中间切换（IHO）状态的条件。如果满足中间切换状态的条件，则服务基站可以启动中间切换状态。

摘要： Systems, methods, and apparatuses for transmitting physical hybrid automatic repetition request indicator channel (PHICH) signals using adaptive code rates are provided. In accordance with one implementation, various PHICH code rates may be supported by configuring a different number of resource element groups (REGs) to transmit the PHICH signai. The information regarding the REGs may be transmitted to a user equipment (UE) in a radio resource control (RRC) message or in an uplink grant message or in a medium access control (MAC) control element. Correspondingly, the UE may detect the PHICH signal with adaptive code rate on the indicated REGs. Furthermore, channel state information (CSi) may be transmitted from the UE to a base station to indicate the measured PHICH quality, such that the base station may determine appropriate PHICH code rate for the UE based on the CSI information.
