    Abstract: Suppression of serving cell transmissions directed to second-served UEs may improve channel estimation of a serving cell or a neighbor cell. This may include using scheduling information for second-served UEs to suppress serving cell signals intended for second-served UEs having overlapping MIMO transmissions. Alternatively, this scheduling information may aid in suppressing a serving cell signal for a second-served UE to improve channel estimation of a neighbor cell. Various embodiments described herein, include implementations and techniques to aid channel estimation, and signal scheduling information to a first-served UE to aid in suppression of serving cell signals for second-served UEs.

    Abstract: For an enhanced physical downlink control channel (EPDCCH), unlimited traffic-to-pilot ratio (TPR) variations across resource elements of a physical resource block (PRB) pair is problematic because of the detrimental affect the variations will have on the ability of a user equipment (UE) to perform inter-cell/intra-cell interference suppression (IS) and/or interference cancellation (IC) on EPDCCH of an interfering cell. A TPR limitation is placed on EPDCCH to facilitate IS/IC without causing practical limitations on EPDCCH management by an eNB. Accordingly, a method, an apparatus, and a computer program product for wireless communication are provided. The apparatus identifies a plurality of resource elements of at least one PRB pair for transmitting one or more control channels, divides the plurality of identified resource elements into one or more groups, and restricts a plurality of resource elements in a respective group to a TPR.

    Abstract translation: 对于增强的物理下行链路控制信道（EPDCCH），物理资源块（PRB）对的资源元素之间的无限的业务导频比（TPR）变化是有问题的，因为不利的变化将对一个 用户设备（UE）在干扰小区的EPDCCH上执行小区间/小区内干扰抑制（IS）和/或干扰消除（IC）。 在EPDCCH上设置TPR限制以便于IS / IC，而不会对eNB的EPDCCH管理造成实际限制。 因此，提供了一种用于无线通信的方法，装置和计算机程序产品。 该装置识别用于发送一个或多个控制信道的至少一个PRB对的多个资源元素，将多个所识别的资源元素划分为一个或多个组，并将相应组中的多个资源元素限制为TPR。

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. In one configuration, the apparatus may be a UE. The UE determines an MCS that would facilitate interference suppression of an interfering first cell transmission from a first cell when decoding a second cell transmission from a second cell at the UE. The interfering first cell transmission is a transmission unintended for the UE. The second cell transmission is a transmission intended for the UE. The UE transmits information indicating the determined MCS for the first cell. The UE receives a transmission including the second cell transmission from the second cell and the interfering first cell transmission from the first cell. The UE demodulates and/or decodes the second cell transmission from the received transmission based on the determined MCS.

    Abstract: Techniques are provided for decoupling uplink and downlink operations. According to certain aspects, a wireless node (e.g., a low power node) may receive, from a base station of a first cell, signaling indicating a random access channel (RACH) configuration for a wireless device. The wireless node may then detect the wireless node performing a RACH detection (based on the RACH configuration) and report the RACH detection and desired UL configuration to the base station of the first cell. The base station of the first cell may then select the wireless node for serving the wireless device for UL operations (e.g., based on the reported RACH detection-and similar reports from other wireless nodes detecting the same RACH procedure).
