摘要： Techniques for adjusting transmit timing of base stations and user equipments (UEs) in a wireless network are described. In one operating scenario, a femto base station communicates with a femto UE, and a macro base station communicates with a macro UE located within the coverage of the femto base station. In an aspect, the transmit timing of the femto base station may be delayed relative to the transmit timing of the macro base station, e.g., to time align downlink signals from the femto and macro base stations at the femto and macro UEs. In another aspect, the transmit timing of the femto UE may be advanced relative to the transmit timing of femto base station by an amount larger than twice the propagation delay between the femto UE and the femto base station, e.g., to time align uplink signals from the femto and macro UEs at the femto base station.

摘要： Aspects disclosed herein relate to channel and interference estimations in a multiple transmission point environment including an eNB and RRHs. In the disclosed aspects, one or more transmission points can signal to a UE to measure channel state conditions based on a first and a second resource pattern. The UE may receive the signaling and perform interference estimation based at least in part on the first resource pattern, and channel estimation based at least in part on the second resource pattern. The UE may generate a channel state report based on the interference and channel estimations, and transmit the channel state report to a transmission point.

摘要： Acknowledgment bundling has been defined for Long Term Evolution (LTE) Time Division Duplex (TDD) systems due to asymmetric DL/UL partitioning. In the case of Frequency Division Duplex (FDD) with a limited uplink (UL) duty cycle, there may be asymmetry associated with a downlink transmission and an associated uplink acknowledgment. For example, there may be a physical downlink shared channel (PDSCH) and a physical uplink control channel (PUCCH) hybrid automatic repeat request acknowledgment (HARQ-ACK) asymmetry. Interference between downlink and uplink transmissions may be a factor contributing to the limited UL duty cycle in an FDD system. For an FDD system having a limited mobile transmission duty cycle, both DL and UL performance may be significantly degraded without proper mitigation techniques. According to certain embodiments of the present disclosure, various HARQ and scheduling techniques may be utilized for minimizing loss due to the limited UL duty cycle.
摘要翻译：由于不对称的DL / UL划分，已经为长期演进（LTE）时分双工（TDD）系统定义了确认捆绑。在具有有限上行链路（UL）占空比的频分双工（FDD）的情况下，可能存在与下行链路传输和相关联的上行链路确认相关联的不对称性。例如，可以存在物理下行链路共享信道（PDSCH）和物理上行链路控制信道（PUCCH）混合自动重传请求确认（HARQ-ACK）不对称性。下行链路和上行链路传输之间的干扰可能是导致FDD系统中限制的UL占空比的因素。对于具有有限移动传输占空比的FDD系统，如果没有适当的缓解技术，DL和UL性能可能会显着降低。根据本公开的某些实施例，可以利用各种HARQ和调度技术来最小化由于有限的UL占空比导致的损失。

摘要： Methods and apparatus for performing radio resource management (RRM) measurements in a heterogeneous network (HetNet) are provided in an effort to prevent failure of RRM measurement procedures in a dominant interference scenario. Several alternatives are provided for determining particular resources (e.g., subframes) to use for performing the RRM measurements, wherein the particular resources are based on cooperative resource partitioning between cells of the HetNet, wherein the cells may be of different types (e.g., macro, pico, or femto cells). These alternatives include, for example: (1) intra-frequency or intra-RAT (radio access technology) alternatives, which may involve transmitting resource partitioning information (RPI) in or deriving non-serving cell RPI based on the serving cell's RPI, as well as (2) inter-frequency or inter-RAT alternatives, where the RRM measurements may be performed during a measurement gap.

摘要： Wireless uplink communication is disclosed which includes dividing information bits into first and second sets of information bits. The first set of information bits is encoded into a first set of coded bits, while the second set of information bits is encoded into a second set of coded bits.

In one example, there is provided a method, operable by a network entity (e.g., evolved Node B), that may involve communicating with another network entity to determine parameters of a quiet period, the parameters comprising at least one of when the quiet period occurs and duration of the quiet period. The method may involve transmitting a reference signal in a first channel exclusively during a first plurality of subframes of a first frame period, wherein the first frame period further includes a quiet period during which no signals are transmitted, and performing during the quiet period a sensing operation with respect to the first channel.

摘要： Methods, systems, apparatus and computer program products are provided to facilitate the transmission of channel status information in wireless systems, such as advanced long-term evolution (LTE-A) systems. Requests for aperiodic channel status reports are generated in systems that use multiple carriers and operate in multiple-in-multiple-out (MIMO) configurations. The request enables a user equipment to configure two transport blocks for the transmission of channel status information only. In some instances, data, in addition to channel status information, is transmitted by the user equipment.
