    摘要： When there are different power classes of base stations (BSs), there may be a need to coordinate transmission from the different BSs to reduce interference to a user equipment (UE) on both control channels and data channels. There are different ways of coordination. For some embodiments, time division multiplex (TDM) resource partitioning may be performed across BSs on a subframe level. TDM resource partitioning may avoid control channel interference since resource mapping on time and frequency for control channels may span the whole frequency domain. However, the data rate for the UE may be limited due to the TDM partitioning of subframes. In other words, a limitation may derive from control channel interference coordination. For some embodiments, a UE may transmit and/or receive in subframes other than the ones partitioned for the UE.

    摘要翻译： 当存在基站（BS）的不同功率等级时，可能需要协调来自不同BS的传输，以减少对控制信道和数据信道上的用户设备（UE）的干扰。 有不同的协调方式。 对于一些实施例，可以在子帧级别上跨越BS执行时分复用（TDM）资源划分。 TDM资源分配可以避免控制信道干扰，因为控制信道的时间和频率上的资源映射可能跨越整个频域。 然而，由于子帧的TDM划分，UE的数据速率可能受到限制。 换句话说，限制可以来自控制信道干扰协调。 对于一些实施例，UE可以在除了为UE分配的子帧之外的子帧中发送和/或接收。

    摘要： Communication in a dominant interference scenario may be supported by performing inter-cell interference coordination (ICIC). Resource coordination/partitioning may be performed to allocate resources to a serving Node B located near the vicinity of a strong interfering Node B. The interfering Node B may avoid transmitting on the allocated/protected resources, possibly except for a common reference signal (CRS). A UE can then communicate with the serving Node B on the protected resources in the presence of the interfering Node B and may observe no interference (possibly except for the CRS) from the interfering Node B. When CRS tones of an interferer may collide with control/data tones of a serving cell, CRS interference cancellation (CRS IC) or puncturing of interfered resource elements (REs) may be appropriate. Certain aspects of the present disclosure provide techniques, where the UE may dynamically switch between CRS IC and RE puncturing based on certain parameters.

    摘要： A method of wireless communication includes determining a number of symbols for uplink control information (UCI) on each of a plurality of layers, multiplexing symbols for the UCI with data on multiple layers such that the symbols are time aligned across the layers, and sending the multiplexed symbols on the multiple layers on uplink. In some designs, the number of symbols for the UCI may be determined based on a spectral resource parameter.
