Abstract: The present disclosure relates to methods and devices for communicating based on improved signaling. A base station can transmit an indication of resources in time and frequency to a UE allocated for NOMA communication with the UE. The indication of resources can comprise a set of NA-RUs. The UE can then transmit uplink NOMA communication to the base station based on the indication of resources received from the base station. Also, the base station can transmit a compact UL resource grant via DCI, or signal the semi-static transport format configuration via RRC, to the UEs allocated for NOMA communication. The DCI or the payload of RRC signaling can be scrambled with a NOMA group RNTI, as well as comprise NOMA transmission parameters indicated by a MCS table. The UE can then transmit uplink NOMA communication to the base station based on the DCI or the RRC signaling.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may apply an open-loop multiple-input multiple-output (MIMO) scheme among a plurality of antenna groups associated with a plurality of antennas, wherein phase coherence cannot be maintained between the plurality of antenna groups; and may apply a closed-loop MIMO scheme among antennas within each antenna group of the plurality of antenna groups, wherein phase coherence can be maintained between antennas included in each antenna group of the plurality of antenna groups. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide a subframe structure for time division duplex (TDD) carriers that can be entirely self-contained. That is, information transmitted on a TDD carrier may be grouped into subframes, where each subframe provides communication in both directions (e.g., uplink and downlink) in a suitable fashion to enable such communication without needing any further information in another subframe. For example, a single subframe may include scheduling information, data information corresponding to the scheduling information, and acknowledgment information corresponding to the data information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a transmission gap for a set of transmissions including a first type of transmission and a second type of transmission based at least in part on at least one of a sounding reference signal parameter, a numerology parameter, or an antenna parameter. In some aspects, the user equipment may transmit at least one transmission, the set of transmissions, in accordance with the transmission gap for the set of transmissions based at least in part on determining the transmission gap for the set of transmissions. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine, when using resource spread multiple access with non-orthogonal multiple access, that a particular modulation scheme is enabled. The user equipment may process symbols using a set of processing sequences selected based at least in part on the particular modulation scheme such that the particular modulation scheme is preserved for the symbols. The user equipment may transmit the symbols based at least in part on processing the symbols using the set of processing sequences. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide techniques for enhanced transmission time interval (TTI) bundling design for machine type communications (MTC). A method for wireless communications by a wireless device is provided. The method generally includes determining a mapping of one or more uplink or downlink channels to one or more fixed bundling sizes, wherein each of the one or more fixed bundling sizes indicates a number of transmission time intervals (TTIs) over which a channel should be transmitted and processing transmission of the one or more uplink or downlink channels based on the mapping.

Abstract: Aspects of the present disclosure provide methods and apparatus for selecting beamforming parameters for uplink transmissions based on an uplink reference signal. An example method generally includes identifying one or more parameters for beamformed transmission to a transmit receive point (TRP), transmitting a reference signal using beamforming in accordance with the identified parameters, and receiving, from the TRP in response to the reference signal, signaling for adjusting the one or more parameters for one or more subsequent beamformed transmissions.

Abstract: Various aspects of the present disclosure provide for methods, apparatus, and computer software for transmitting a common uplink burst in time division duplex (TDD) carriers. The common uplink burst includes a sounding reference signal (SRS) transmitted separate from (e.g., decoupled from) a demodulation reference signal (DM-RS). At least one symbol in the common uplink burst includes a control region for carrying control information and a data region for carrying data information. The SRS may be precoded separately from precoding of the control and data regions, so that the control and/or data information may be transmitted utilizing multiple input multiple output (MIMO).
