Abstract: Described are methods, apparatuses, and computer-readable mediums of enabling transmission of feedback for a mixture of pre-timed and on-demand acknowledgements. In an example, an apparatus receives a first transmission and a second transmission. The apparatus determines that the first transmission is associated with pre-timed acknowledgement rules and also determines that the second transmission is associated with on-demand acknowledgement rules. The apparatus transmits a first acknowledgement of the first transmission according to the pre-timed acknowledgement rules and transmits a second acknowledgement of the second transmission according to the on-demand acknowledgement rules.

Abstract: Techniques for broadcast channel management on a shared communication medium are disclosed. An access terminal may be configured to identify a subframe number associated with a given subframe based not only on a subframe number indicator but also a reference boundary. Conversely, an access point may be configured to set a subframe number indicator for a given subframe based not only on its subframe number but also a reference boundary.

Abstract: Techniques for control channel signaling on a shared communication medium are disclosed. An access point or an access terminal may communicate over a communication medium in accordance with a Time Division Duplex (TDD) frame structure defining a set of subframes that each span a plurality of time-domain symbol periods. The access point may transmit and the access terminal may receive control information via a short Physical Uplink Control Channel (sPUCCH) on one or more of the subframes in a portion of the subframe configured for uplink signaling. The sPUCCH may comprise one or more pilot symbols and one or more payload symbols that collectively occupy a subset of less than all of the symbol periods in each of the one or more subframes.

Abstract: Systems, methods, and apparatuses for detecting interference caused by a wireless local area network (WLAN) and a wireless wide area network (WWAN) node operating in an unlicensed or shared spectrum is disclosed. In accordance with the present disclosure, a base station may generate a null tone pattern for one or more subframes transmitted to the UE. The null tone pattern may include one or more null tones mapped to consecutive symbols in each resource block to detect interference. Accordingly, a UE may monitor a wireless channel from a base station for a null tone transmission. The UE may detect a null tone pattern by decoding a known physical layer channel to identify the null tone pattern. In some aspects, the UE may generate channel estimates, decode allocated resources, determine timing of future transmissions and/or establish communication with the base station based on the identified null tone pattern.
Abstract translation: 公开了用于检测由无线局域网（WLAN）和在非许可或共享频谱中操作的无线广域网（WWAN）节点引起的干扰的系统，方法和装置。 根据本公开，基站可以为发送给UE的一个或多个子帧生成空调模式。 空色调模式可以包括映射到每个资源块中的连续符号的一个或多个空音调以检测干扰。 因此，UE可以监视来自基站的无线信道用于零音调传输。 UE可以通过解码已知的物理层信道来识别空色调模式来检测空色调模式。 在一些方面，UE可以基于所识别的空色调模式来生成信道估计，解码分配的资源，确定将来传输的定时和/或建立与基站的通信。
