Abstract: Systems, methodologies, and devices are described that can facilitate reducing power consumption associated with mobile devices. A mobile device can utilize a sleep mode controller that can facilitate selecting and/or switching to a desired sleep mode based in part on predefined sleep mode criteria. The sleep modes can include a non-sleep mode, light sleep mode, and/or deep sleep mode. The mobile device can employ an analyzer to evaluate information related to explicit signals, implicit signals, and/or the current sleep mode to determine whether a condition is met based in part on the predefined sleep mode criteria such that a transition to a different sleep mode is to be performed. If such a condition is met, the sleep mode controller can facilitate transitioning from the current sleep mode to a different sleep mode to facilitate reducing power consumption by the mobile device.

Abstract: Methods, systems, and devices are described for supporting common reference signaling in wireless communications systems. Some configurations introduce a phase discontinuity between common reference signal (CRS) transmissions on different subframes. This may address issues that may arise when a reduced CRS periodicity is utilized. Indicators may also be transmitted from base stations to user equipment (UEs) to indicate whether phase continuity may be assumed or not. Some configurations may support CRS sequence initialization. These tools and techniques may utilize an extended CRS sequence periodicity, which may increase the number of CRS sequences transmitted by a cell.

Abstract: Methods, systems, and apparatuses for enabling and utilizing variable length transmission time intervals (TTI) are described. Latency for communications between base stations and user equipment (UEs) may be reduced by flexibly and dynamically adapting to data traffic needs. TTI for a given UE may be dynamically adjusted according to UE or system requirements and the configuration of uplink and downlink TTI. A base station may utilize dynamic grants to schedule resources within a system. A UE may receive a grant in a first portion of a variable TTI. The UE may determine a duration of the variable TTI based on the grant, and the UE may communicate accordingly. The UE may receive a subsequent grant in the variable TTI—either in the first portion or another portion—and may respond or alter its operation accordingly.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with specifying a traffic-to-pilot (T/P) ratio per subframe and/or resource block to allow a base station to transmit over the subframes and/or resource blocks using varying transmit powers. In one example, a device communicating with the base station can receive a plurality of T/P ratios each related to a power used by the base station to transmit over one of a plurality of carriers in a specific subframe or resource block, determine a power of a reference signal received from the base station over a carrier of the plurality of carriers, and process a data signal received over the carrier within the specific subframe or resource block based in part on applying, to the power of the reference signal, a T/P ratio of the plurality of T/P ratios corresponding to the carrier.

Abstract: When enabled with common reference signal interference cancellation, 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: 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.

Abstract translation: 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性的SPS授权可能需要改变，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。
