摘要： Time division multiplexing (TDM) partitioning is one of the inter-cell interference coordination (ICIC) mechanisms considered for a heterogeneous network (HetNet) ICIC in a co-channel deployment. For example, in subframes that are pre-allocated to an evolved Node B (eNB), neighbor eNBs may not transmit, hence interference experienced by served user equipments (UEs) may be reduced. Semi-persistent scheduling (SPS) grants may have various available periodicities, which may not be compatible with TDM partitioning. Therefore, a UE may miss an SPS opportunity that was scheduled for a subframe that was not usable by the UE. Hence, using SPS grants with small periodicities in a heterogeneous network with TDM partitioning may require changes which may include adjusting the periodicities of the SPS grants, rescheduling of uplink SPS messages based on resource partitioning information (RPI), and/or determining RPI based on current SPS grants.
摘要翻译：时分复用（TDM）分区是在同频道部署中为异构网络（HetNet）ICIC考虑的小区间干扰协调（ICIC）机制之一。例如，在预分配给演进节点B（eNB）的子帧中，相邻eNB可能不发送，因此可能减少被服务用户设备（UE）经历的干扰。半静态调度（SPS）授权可能具有各种可用的周期性，这可能与TDM分区不兼容。因此，UE可能错过针对UE不可用的子帧调度的SPS机会。因此，在具有TDM分割的异构网络中使用具有小周期的SPS许可可能需要改变，其可以包括调整SPS授权的周期性，基于资源划分信息（RPI）重新安排上行SPS消息，和/或基于当前SPS赠款。

摘要： Aspects of the present disclosure relate generally to wireless communication systems, and more particularly, to systems and methods for managing inter-cell interference coordination (ICIC) actions for time-domain partitioned cells. In certain aspects, time-domain partitioning is accounted for by an ebb in determining whether to send frequency-based inter-cell interference information (e.g., uplink overload indicator) to neighboring ebb(s) and/or responsive actions to take in response to receiving frequency-based inter-cell interference information (e.g., uplink overload indicator, high interference indicator, and/or relative narrowband transmission power).

摘要： A method for determining channel quality estimates of two or more types of subframes, such as clean and unclean subframes, may be applicable to both legacy and newer user equipment. A first base station affects a channel quality measurement by either transmitting dummy signals over designed tones that correspond to a second base station, or by puncturing transmissions during designated tones that correspond to the second base station.

摘要： A method and apparatus are for communication in a wireless network in which a User Equipment (UE) associated with a first evolved Node B (eNB) experiences interference from a second eNB. The method includes negotiating by the first eNB of the wireless network with a second eNB of the wireless network for a partitioning of subband resources on an uplink. A first subset of subband resources is assigned to the first eNB, and a second subset of subband resources is assigned to the second eNB. A method and apparatus are for communication in a wireless network. The method includes decoding a downlink control channel received during a protected downlink subframe to determine an uplink subframe n containing a protected subband for uplink transmission. The method also includes transmitting data during the uplink subframe n on the protected subband.
