Abstract: Systems and methods are disclosed for control-data multiplexing as well as control-data decoupling. In one embodiment, a semi-static approach is disclosed, wherein the upper layer(s) are configured such that each user equipment uses either control-data multiplexing or control-data decoupling. Additionally or alternatively, a dynamic approach is disclosed, in which one bit is added to the DCI format which indicates whether the UE is using control-data multiplexing or control-data coupling.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications, and more specifically to enhanced paging procedures for devices with limited communications resources, such as machine type communication (MTC) devices and enhanced or evolved MTC (eMTC) devices. An example method generally includes determining a set of subframes corresponding to a paging occasion for the UE to receive a paging message from a base station (BS), determining, within the set of subframes, at least one narrowband region for receiving the paging message, and monitoring for the paging message in the at least one narrowband region within the set of subframes.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that a size of an uplink control information (UCI) part exceeds a UCI part payload size limit, wherein the UCI part includes hybrid automatic repeat request acknowledgment information (HARQ-ACK), and may selectively transmit the UCI part based at least in part on determining that the size of the UCI part exceeds the UCI part payload size limit. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for compact downlink control information (DCI) signaling design for ultra-reliable low-latency communications (URLLC). A method for wireless communications performed by a base station (BS) is provided. The method generally includes generating DCI, the DCI scheduling at least one transmission, according to a first DCI format. The first DCI format is compressed relative to a second DCI format and includes a carrier indicator field (CIF) and/or a rate-matching indicator field. The BS transmits the DCI to a user equipment (UE). The UE communicates with the BS based on the received DCI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a set of physical uplink control channel (PUCCH) resources to be used to transmit a channel state information (CSI) payload based at least in part on a first rank that is independent of a second rank used to construct the CSI payload; and transmit the CSI payload, to a base station (BS), using one or more resources from the set of PUCCH resources. Numerous other aspects are provided.

Abstract: A method and apparatus for demodulation reference signal (DMRS) communication are described. The method and apparatus include determining a DMRS pattern for at least two multiplexing schemes. In some aspects, the at least two multiplexing schemes may include orthogonal frequency-division multiplexing (OFDM) and single carrier frequency-division multiplexing (SC-FDM). Further, in some aspects, the DMRS pattern may correspond to a continuous tone pattern in each subframe transmitted in accordance with both SC-FDM and OFDM. Additionally, in some aspects, the DMRS pattern may correspond to a comb tone pattern in each subframe transmitted in accordance with both SC-FDM and OFDM. The method and apparatus further include transmitting a DMRS in accordance with at least one of the two multiplexing schemes and based on the DMRS pattern.

Abstract: Aspects of the present disclosure provide techniques that may be used by a BS and/or UE to reduce the time associated with performing cell acquisition. An exemplary method, performed by a BS, generally includes determining opportunities for assisting cell acquisition by one or more UEs, and boosting transmission power for one or more signals used for cell acquisition during the determined opportunities. Another exemplary method, performed by a UE, generally includes exiting a first low power state in order to perform cell acquisition based on one or more signals transmitted by a base station, and taking one or more actions to reduce acquisition time when performing the cell acquisition.

Abstract: Processing relaxation for aperiodic channel state information (CSI) reference signal (CSI-RS) is discussed for networks that include full dimension multiple input, multiple output (FD-MIMO) operations. A user equipment (UE) operating in such a system monitors for the presence of aperiodic CSI-RS. When such aperiodic CSI-RS are detected, the UE may provide process relaxation in CSI reporting by transmitting aperiodic CSI reporting according to an uplink shared channel limitation, or by relaxing the processing of the aperiodic CSI reporting transmitted by the UE, or a combination of both.

Abstract: In eMTC, channels may be bundled, using repetitions in multiple subframes. SPS and DRX for eMTC may not accommodate such repetitions, because repetitions for a bundled channel may fall only partially within a DRX ON duration. An apparatus addresses this problem by determining a DRX ON duration, determining a set of subframes carrying a bundled M-PDCCH candidate and determining that the DRX ON duration at least partially overlaps with the set of subframes of the bundled M-PDCCH. The apparatus then refrains from decoding the first bundled M-PDCCH candidate, decodes the first bundled M-PDCCH candidate, or extends the DRX ON duration to include the set of subframes entirely and decoding the first bundled M-PDCCH candidate carried in the set of subframes in the extended DRX ON duration. The apparatus may also determine DRX configuration parameters based on parameters of bundled channels, and handle invalid subframes for an SPS grant.

Abstract: Aspects of the present disclosure provide techniques for design of synchronization signals for narrowband operation and other clean-slate, OFDM based systems such as enhanced component carrier (eCC) systems. An example method is provided for operations which may be performed by a BS to generate and transmit a dual-layer PSS, and correspondingly, techniques for a UE to detect the dual-layer PSS. The PSS may be generated utilizing a binary code cover and at least one sequence applied to a number of symbols within one or more subframes of a frame.
