    Abstract: In general, to provide acknowledgment information by a first wireless device, the first wireless device sends repeated instances of acknowledgment information in respective first and second frame structures, in response to receipt of first information from a second wireless device. In addition, the first wireless device also sends further acknowledgment information in the second frame structure that is responsive to second information received from the second wireless device.

    Abstract: Neighbor cell hearability can be improved by including an additional reference signal that can be detected at a low sensitivity and a low signal-to-noise ratio, by introducing non-unity frequency reuse for the signals used for a time difference of arrival (TDOA) measurement, e.g., orthogonality of signals transmitted from the serving cell sites and the various neighbor cell sites. The new reference signal, called the TDOA-RS, is proposed to improve the hearability of neighbor cells in a cellular network that deploys 3GPP EUTRAN (LTE) system, and the TDOA-RS can be transmitted in any resource blocks (RB) for PDSCH and/or MBSFN subframe, regardless of whether the latter is on a carrier supporting both PMCH and PDSCH or not. Besides the additional TDOA-RS reference signal, an additional synchronization signal (TDOA-sync) may also be included to improve the hearability of neighbor cells.

    Abstract translation: 通过对于用于到达时差（TDOA）的信号引入非单位频率重用，可以通过包括可以在低灵敏度和低信噪比下检测的附加参考信号来提高邻近小区的可听性， 测量，例如从服务小区站点和各个相邻小区站点发送的信号的正交性。 提出了称为TDOA-RS的新参考信号，以提高部署3GPP EUTRAN（LTE）系统的蜂窝网络中的相邻小区的可听性，并且可以在用于PDSCH的任何资源块（RB）中发送TDOA-RS 和/或MBSFN子帧，而不管后者是否在支持PMCH和PDSCH两者的载波上。 除了附加的TDOA-RS参考信号之外，还可以包括附加同步信号（TDOA-sync）以提高相邻小区的可听性。

    Abstract: Display-to-touch noise may be perceptible when a touch image generated during an active period of an electronic display of an electronic device is used to determine a touch indication on the display. The electronic device may include a display pixel layer including a plurality of display pixels that write display images to the display during a display active period and continue displaying the display image during a display blanking period. The electronic device may also include a touch sense layer including a plurality of touch sense pixels that facilitate generation of a first touch image during a first display active period and generation of a second touch image during a first display blanking period. The electronic device may further include a controller coupled to the display pixel layer and the touch sense layer that facilitates the reduction or elimination of display-to-touch interference. In particular, the controller may determine a first noise metric associated with touch images generated during the first display active period and a second noise metric associated with touch images generated during the first display blanking period. Further, the controller may instruct the touch sense layer to not generate touch images during a second display active period in response to the first noise metric being greater than a noise threshold and the second noise metric not being greater than the noise threshold.
