Abstract: Certain aspects of the present disclosure relate to methods and apparatus for determining support for one or more modulation orders to use for the transmission of control channel(s) and data channel(s). In one aspect, a user equipment (UE) determines, based on at least three modulation and coding scheme (MCS) tables, a first modulation scheme to use for communications with a wireless device for a first subset of subframes, and a second modulation scheme to use for communications with the wireless device for a second subset of subframes. Each of the three MCS tables is associated with a different maximum modulation order. The UE monitors for a data channel transmitted in the first subset of subframes using the first modulation scheme. The UE monitors for a data channel transmitted in the second subset of subframes using the second modulation scheme.

Abstract: Aspects of the present disclosure provide techniques for design of synchronization signals for narrowband operation, which can be used for stand-alone/in-band/guard-band deployment. An example method is provided for operations which may be performed by a base station (BS). The example method generally includes generating a primary synchronization signal (PSS) utilizing a first code sequence and a cover code applied to the first code sequence over a first number of symbols within one or more subframes, generating a secondary synchronization signal (SSS) based on a second code sequence over a second number of symbols within one or more subframes, and transmitting the PSS and the SSS in the first and second subframes to a first type of a user equipment (UE) that communicates on one or more narrowband regions of wider system bandwidth.

Abstract: Certain aspects of the present disclosure relate to techniques for cross-carrier indication of TDD (Time Division Duplex) UL (Uplink)/DL (Downlink) subframe configuration. A UE may receive a configuration of a first index for a first cell, wherein the first index is mapped to a first position in a Downlink Control Information (DCI) message. The UE may receive the DCI message in a subframe and determine an indication of a UL/DL subframe configuration for the first cell based on the first index and the DCI message. The UE may communicate with the first cell based on the determined UL/DL subframe configuration for the first cell.

Abstract: In the present disclosure, CSI and/or a plurality of ACK/NACKs related to a group of DL data transmissions may be buffered at the UE as a GACK until a DCI trigger is received from the eNB. When the DCI trigger is received, the UE may transmit the CSI and/or GACK. In this way, HARQ feedback and/or CSI may be reliably communicated even if a CCA does not clear and/or UL subframes are unavailable. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In an aspect, the apparatus may be a UE. The apparatus monitors one or more subframes for a DCI trigger. In a further aspect, the apparatus receives the DCI trigger in a subframe. In another aspect, the apparatus transmits UCI using a subsequent subframe.
