Abstract: Techniques for addressing high interference observed by a receiver in a wireless communication system are disclosed. The receiver may observe different interference power levels across a transmission symbol. In an aspect, the receiver applies different weights to different portions of the transmission symbol to account for fluctuation of interference power across the transmission symbol. In another aspect, a transmitter may send a transmission symbol such that a receiver can ignore a portion of a symbol period with high interference. In one design, the transmitter generates a transmission symbol including at least two copies of a signal component. The transmitter transmits at least one copy of the signal component in a portion of the symbol period in which the receiver does not observe high interference. The receiver processes the at least one copy of the signal component to recover data sent in the transmission symbol.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE identifies properties associated with reference signals of a received payload. The properties associated with reference signals of the received payload may include a reference signal structure and/or a traffic to pilot ratio. The UE determines a payload structure based on the identified properties. Subsequently, the UE decodes the received payload based on the determined payload structure. The UE may receive mapping information indicating a mapping between possible properties associated with reference signals and possible payload structures. The UE may determine the payload structure further based on the received mapping information. The UE may receive the mapping information through a broadcast or RRC signaling.

Abstract: A method of wireless communication occurs in a frequency band having a first set of resources associated with a first carrier type and a second set of resources associated with a second carrier type. In one configuration, the first carrier type is a new carrier type and the second carrier type is a legacy carrier type. Legacy UEs may only receive signals from the second carrier type. However, new UEs may receive signals from both the first carrier type and the second carrier type. Therefore, to provide backward compatibility while supporting new UEs, an eNodeB may signal support of the first carrier type to a new UE while maintaining signaling with legacy UEs. Additionally, the eNodeB may restrict operations of a UE to the first set of resources or second set of resources.

Abstract translation: 无线通信的方法发生在具有与第一载波类型相关联的第一资源集合的频带和与第二载波类型相关联的第二资源集合的频带中。 在一种配置中，第一载波类型是新载波类型，第二载波类型是传统载波类型。 旧的UE可能只接收来自第二载波类型的信号。 然而，新的UE可以从第一载波类型和第二载波类型两者接收信号。 因此，为了在支持新的UE的同时提供向后兼容性，eNodeB可以向新的UE发送对第一载波类型的支持，同时保持与传统UE的信令。 另外，eNodeB可以将UE的操作限制为第一组资源或第二组资源。

Abstract: A method of wireless communication includes receiving activation parameters at a low power node and detecting a proximity of an active user equipment (UE) based at least in part on the activation parameters. The activation parameters are triggered from a node different from the low power node, such as an eNodeB. The low power node initiates an activation sequence after detecting the active UE.

Abstract: When enabled with common reference signal interference cancelation, a user equipment (UE) may still compute a channel state feedback value with consideration of any canceled interfering neighboring signals. When the neighboring cells are determined to be transmitting data during the time for which the channel state feedback value is being computed, the UE is able to derive the channel state feedback value considering those canceled interfering signals. The UE determines whether each neighboring cell is transmitting during the designated time either by obtaining signals that indicate the transmission schedule of the neighboring cells or by detecting the transmission schedule, such as based on the power class of the neighboring cells. If the UE determines that the neighboring cells are transmitting data during this time period, the UE will compute the channel state feedback value including consideration of the canceled interfering signals.

Abstract translation: 当使用公共参考信号干扰消除时，用户设备（UE）仍可以考虑任何取消的干扰相邻信号来计算信道状态反馈值。 当在正在计算信道状态反馈值的时间内确定相邻小区正在发送数据时，UE能够导出考虑到那些被消除的干扰信号的信道状态反馈值。 UE通过获得指示相邻小区的传输调度的信号或者通过基于相邻小区的功率等级来检测传输调度来确定在指定时间期间每个相邻小区是否正在发射。 如果UE在该时间段期间确定相邻小区正在发送数据，则UE将计算包括考虑被消除的干扰信号的信道状态反馈值。

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided for separating control transmissions and data transmissions within the coverage area of a plurality of transmission/reception points or points that are geographically displaced, the plurality of points comprising a macro node and a plurality of remote radio heads (RRHs) coupled to the macro node. Separating control transmissions and data transmissions in the macro node/RRH configuration may allow UEs to be associated with one set of transmission points for data transmissions and the same set or a different set of transmission points for common control signaling. Separating control transmissions and data transmissions may also allow for faster reconfiguration of antenna ports used for UE data transmission compared with reconfiguration via a handover process.
