Abstract: Various aspects described herein relate to techniques for timing control with filtering in orthogonal frequency division multiplexing (OFDM)-based wireless communications systems. In an aspect, the method includes determining whether time-domain filtering or frequency-domain filtering is used for a transmission signal waveform, and identifying a time delay based on a determination that the time-domain filtering is used for the transmission signal waveform. The method further includes applying a timing correction based on the identified time delay. The techniques described herein may apply to different communications technologies, including 5th Generation (5G) New Radio (NR) communications technology.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus maybe a base station or a UE. In an aspect, the apparatus may determine locations for a number of DM-RS symbols to be transmitted in a scheduling unit of a channel configured in a slot/mini-slot, where a last DM-RS symbol maybe positioned one symbol prior to a last symbol carrying scheduled data. In another aspect, the apparatus may determine the locations for the DM-RS symbols based on a selection between a first set of predetermined DM-RS positions and a second set of predetermined DM-RS positions. In another aspect, the apparatus may determine the locations for the DM-RS symbols based on a set number of symbols, wherein the determined locations are spaced apart according to the set number of symbols. The apparatus may transmit the DM-RS symbols based on the determined locations.

Abstract: Aspects of the present disclosure relate to deriving spatial receive parameters for quasi-colocation at a user equipment (UE). An exemplary method generally includes receiving a plurality of beams from a base station in a plurality of coarse directions, determining, based on the plurality of beams, a first spatial colocation parameter, transmitting an indication of a coarse direction associated with a beam having a highest receive strength of the plurality of beams, receiving a plurality of second beams from the base station based on the indication, the plurality of second beams having a narrower beam width than the plurality of beams and covering a beam width of the beam associated with the indicated coarse direction, determining, based on the plurality of second beams, a second spatial colocation parameter, transmitting an indication of the second beam having a highest receive strength, and refining at least one of the first or second spatial colocation parameters.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus methods and apparatus for multiplexing demodulation reference signals (DMRS) and synchronization signals (SS) in new radio (NR). An exemplary method that may be performed by a base station (BS) includes determining transmission resources, in a set of slots, to be used for first demodulation reference signals (DMRS), based on whether synchronization signals (SS) are to be transmitted in the set of slots, and transmitting the first DMRS using the transmission resources in the set of slots.

Abstract: Aspects of the present disclosure relate to techniques that may enhance radio link failure (RLF) procedures. In some cases, a UE may perform radio link monitoring (RLM) based on reference signals (RS) transmitted using a first set of beams, perform beam failure recovery (BFR) monitoring based on transmissions using a second set of beams, and adjust one or more radio link failure (RLF) parameters based on both the RLM monitoring and the BFR monitoring.

Abstract: Aspects of the present disclosure generally relate to a conditional utilization of reference signals for managing communications of one or more user equipment (UE) in a wireless communications system. The described aspects include receiving a transmission having a first subframe slot and a second subframe slot, at least one of the first subframe slot and the second subframe slot have a single-slot transmission time interval (TTI). The described aspects further include detecting a first demodulation reference signal (DM-RS) in the first subframe slot and a second DM-RS in the second subframe slot. The described aspects further include determining whether to demodulate the at least one downlink channel in the first subframe slot using the first DM-RS in the first subframe slot or to demodulate both the first DM-RS in the first subframe slot and the second DM-RS in the second subframe slot based on whether at least one condition exists.

Abstract: A method or apparatus for wireless communication at a scheduling entity communicating with a plurality of devices over a plurality of links in a shared spectrum in a way to avoid undue interference among the plurality of links. The apparatus receives a set of priority indicators, each priority indicator corresponding to time varying priorities for communicating over the plurality of links. The apparatus assigns each of the plurality of links a subset of the set of priority indicators. Each priority indicator maps to a time varying priority level for the communication during each of a plurality of frames. The apparatus may also receive an indication of a mapping function for determining the corresponding priority level for each priority indicator according to a frame number. Links assigned disjoint priority indicators may have TDM transmissions, whereas links having an overlapping priority indicator may have simultaneous transmissions.
