    Abstract: Systems, methods, and devices for wireless communication that support mechanisms for non-coherent, sequence-based downlink control signaling in a wireless communication system. In aspects, the mechanisms for non-coherent, sequence-based downlink control signaling may include a new non-coherent, sequence-based downlink control channel or signal transmitted from a base station to a user equipment (UE) and configured to convey information bits (e.g., control information bits) to the UE. The UE may receive a signal transmitted over the new non-coherent, sequence-based downlink control channel and may decode the signal to extract the control information. The UE may then apply a control based on the control information received from the base station in the signal over the non-coherent, sequence-based downlink control channel.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling identifying a configuration for a reference signal comprising a single carrier waveform and associated with single carrier signals for a plurality of symbol periods, the configuration indicating a plurality of channels associated with the reference signal and a set of functions associated with the reference signal. The UE may receive, according to the configuration, the reference signal in a first one or more symbol periods of the plurality of symbol periods and the single carrier signals on the plurality of channels in a second one or more symbol periods of the plurality of symbol periods. The UE may perform the set of functions on the received single carrier signals based at least in part on the received reference signal.

    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may account for propagation delay when initiating a random access (RACH) procedure. For example, the UE may determine transmission timing for a RACH preamble based on an estimated propagation delay, such that the RACH preamble is received at a base station approximately at the beginning of a slot. To support reliable communication of the RACH preamble, the UE may implement a timing offset. In some examples, the base station may configure the UE with the timing offset using system information. Alternatively, the UE may be pre-configured with the timing offset. By determining the transmission timing for the RACH preamble further based on the timing offset, the UE may ensure that the RACH preamble is received at the base station after a slot boundary (e.g., avoiding causing interference to communications in a previous slot).

    Abstract: The apparatus is configured to transmit and/or receive GDMRS that may be scrambled based on a same scrambling identifier (ID) and shared for a plurality of UEs or channels. The apparatus, in some configurations, is further configured to multiplex, in time, data for the plurality of UEs or channels into different segments within each symbol in a set of symbols. The apparatus is further configured to transmit and/or receive the multiplexed data for the plurality of UEs or channels. In some configurations, the apparatus is further configured to demodulate the received data based on the GDMRS, and extract at least one segment for a UE or a plurality of channels associated with the apparatus within the demodulated data for subsequent decoding at the apparatus. In some configurations the extraction is based on a SLIV transmitted and/or received by the apparatus.
