Abstract: Measurement and demodulation may be impacted by varying transmit power due to varying numbers of carriers in a shared radio frequency (RF) spectrum band. Methods, systems, and devices are described for wireless communication. One method includes monitoring at least one carrier of a RF spectrum band for a first reference signal transmitted in a number of listen-before-talk (LBT) radio frames from a plurality of LBT radio frames associated with the plurality of carriers, where the plurality of LBT radio frames are received at the user equipment (UE) in different sets of at least one carrier of the RF spectrum band at different times, and where the first reference signal is associated with a first fixed transmit power; receiving a plurality of instances of the first reference signal; measuring the plurality of instances; and determining a cell measurement based at least in part on the measurements of the plurality of instances.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may perform one or more process that enable smart processing of resource elements from interfering base stations in order to improve cell decoding. The method includes prioritizing resource elements in order to reduce complexity of processing of the interfering resource elements. Some resource elements may be excluded from processing if priority is set to a null value or to a sufficiently low value. Resource elements in a subframe received from an interfering transmitter are grouped into one or more target regions and paired with serving and interfering cells. Each pairing is prioritized and processed in an order based on the priorities assigned to the pairings.

Abstract: Coding for bursty interference is discussed in which a base station receives data bits for transmission. The base station may generate code blocks including information bits and parity bits. The base station may also generate parity check code blocks including information bits corresponding to information bits of the generated code blocks. The base station may transmit the code blocks and the parity check code blocks to a mobile device to improve decoding. When errors are detected, the mobile device may decode the received code blocks using hard or soft parity checks and the parity check code blocks.

Abstract: Reported CSI may not reflect non-cancelable CRS interference received from an interfering cell, such as when the CSI is computed when CRS interference is not received. To address the issue, a user equipment (UE) may determine an interference cancelation/suppression efficiency (CSE) associated with canceling/suppressing interference from interfering cells. In addition, based on the determined CSE, a UE may compute CSI such that the CSI reflects the true cancelation efficiency of the UE with respect to interfering cell signals. When computing the CSI based on the determined CSE, the UE may report that the CSI is worse than it is to reflect the UE's true cancelation efficiency with respect to the interfering cell signals.

Abstract translation: 报告的CSI可能不反映从干扰小区接收的不可取消的CRS干扰，例如当没有接收到CRS干扰时计算CSI。 为了解决该问题，用户设备（UE）可以确定与抵消/抑制来自干扰小区的干扰相关联的干扰消除/抑制效率（CSE）。 另外，基于所确定的CSE，UE可以计算CSI，使得CSI相对于干扰小区信号反映UE的真实消除效率。 当基于确定的CSE计算CSI时，UE可以报告CSI比反映UE相对于干扰小区信号的真实消除效率更差。

Abstract: Techniques are described for preempting resource allocations to one or more UEs in the event that delay sensitive data is received. A resource allocation of a number of symbols may be granted to a first user equipment (UE) for first associated data to be transmitted. Subsequently, data may be received for a second UE that is more delay sensitive than the first data. The resource allocation to the first UE may be preempted, and resources allocated to the second UE for the second data within a variable length transmission time interval (TTI) of the resource allocation to the first UE. UEs may monitor for preemption during transmissions to other UEs in order to receive new resource grants associated with the preempted resource grant. Whether a UE monitors transmissions for preemption may be determined based on a quality or service (QoS) of the UE.

Abstract: Channel state information (CSI) request procedures are disclosed for use in long term evolution (LTE)/LTE-Advanced (LTE-A) networks with unlicensed spectrum. Instead of relying on periodic reference signals which may not be transmitted because of failed clear channel assessment (CCA) operations, an aperiodic reference signal is defined that provides an on-demand reference signal and CSI request for user equipment (UE). The serving base station transmits an identifier, which signals that the aperiodic reference signal will be transmitted, either in the same subframe or a future subframe, and then transmits the aperiodic reference signal in the designated subframe. UEs served by the base station will receive the identifier, identify a CSI request, either implicitly through the identifier signal received from the base station or explicitly through a UE-specific CSI request, and then generate a CSI report based on the aperiodic reference signal for transmission back to the serving base station.

Abstract translation: 信道状态信息（CSI）请求程序被公开用于具有非许可频谱的长期演进（LTE）/ LTE-高级（LTE-A）网络。 不是依赖于由于清除信道评估（CCA）操作失败而不能发送的周期性参考信号，而是定义提供用户设备（UE）的按需参考信号和CSI请求的非周期性参考信号。 服务基站在同一子帧或将来的子帧中发送用于发送非周期参考信号的标识符，然后在指定的子帧中发送非周期性参考信号。 由基站服务的UE将通过从基站接收到的标识符信号或通过UE特定的CSI请求明确地接收标识符，识别CSI请求，然后基于非周期参考信号生成CSI报告， 传输回服务基站。

Abstract: Parameters associated with an interfering downlink transmission may be determined at the UE or may be signaled to the UE from an eNodeB. The parameters may be actual parameters or hypothetical parameters. Based on the parameters, the UE may determine a metric that reflects an amount of interference cancelled from the interfering data channel transmission. The UE determines a quasi-clean channel state information and/or interference efficiency based on the parameters. The UE may transmit the quasi-clean CSI and/or the interference efficiency to the eNodeB.

Abstract: Methods, systems, and devices are described for hierarchical communications and low latency support within a wireless communications system. An eNB and/or a UE may be configured to operate within the wireless communications system which is at least partially defined through a first layer with first layer transmissions having a first subframe type and a second layer with second layer transmissions having a second subframe type. The first subframe type may have a first round trip time (RTT) between transmission and acknowledgment of receipt of the transmission, and the second layer may have a second RTT that is less than the first RTT. Subframes of the first subframe type may be multiplexed with subframes of the second subframe type, such as through time division multiplexing. In some examples symbols of different duration may be multiplexed such that they different symbol durations coexist.

Abstract: Systems and methodologies are described that facilitate dynamically forming clusters in a wireless communication environment. A set of non-overlapping clusters can be formed dynamically over time and in a distributed manner. Each of the clusters can include a set of base stations and a set of mobile devices. The clusters can be yielded based upon a set of local strategies selected by base stations across the network converged upon through message passing. For example, each base station can select a particular local strategy as a function of time based upon network-wide utility estimates respectively conditioned upon implementation of the particular local strategy and disparate possible local strategies that can cover the corresponding base station. Moreover, operation within each of the clusters can be coordinated.
