Abstract: The present disclosure relates to signaling information in physical broadcast channel (PBCH) demodulation reference signals (DMRS). In one example, a network entity may transmit the signaling information carried by a DMRS in one or more resource elements of physical broadcast channel (PBCH) symbols within a bandwidth of a primary synchronization signal and a secondary synchronization signal of a synchronization signal block. In another example, a user equipment (UE) may receive the signaling information carried by the DMRS within one or more resource elements of PBCH symbols within a bandwidth of a primary synchronization signal and a secondary synchronization signal of a synchronization signal block on a broadcast channel from the network entity.

Abstract: Techniques for signaling dynamic control region for PRACH transmission are described. In an aspect, the disclosure describes a method for receiving, at a user equipment (UE), an indication of a number of control symbols that the UE is to assume when transmitting physical random access channel (PRACH), and transmitting, by the UE, the PRACH over one or more slots based on the number of control symbols. In another aspect, the disclosure describes a method for generating, at a network device, an indication of a number of control symbols that a UE is to assume when transmitting PRACH, transmitting, by the network device, the indication to the UE. A UE and network device configuration as well as apparatuses and computer-readable medium related to these methods are also described.

Abstract: A first apparatus may communicate with a user equipment through a first active beam. The first apparatus may determine that beam tracking is to be performed with the UE, including identifying a new beam for communication between the UE and the apparatus. The first apparatus may perform beam tracking with the UE based on the determination that beam tracking is to be performed. The first apparatus may communicate with the UE through a second active beam based on the beam tracking.

Abstract: Adjacent channel leakage-power ratio (ACLR) can be reduced at a transmitter of a device. A modulated signal can be mapped into a plurality of tone sets in a frequency domain, wherein the plurality of tone sets include a first, a second, and a third set of tones. The first and the third set of tones can be converted in the frequency domain to a fourth and a fifth set of tones, respectively, in a time domain. A zero padding of one or more symbols associated with the fourth and the fifth set of tones can be performed to output a sixth and a seventh set of tones, respectively. The sixth and the seventh set of tones can be converted to an eighth and a ninth set of tones, respectively, in the frequency domain. The eighth and the ninth set of tones can be processed for transmitting to another wireless device.

Abstract: Aspects of the present disclosure provide a mechanism for flexible scheduling of grants for downlink or uplink transmissions. In some examples, a grant may be scheduled using multiple control signals, where subsequent control signals may modify one or more properties of the grant. For example, the grant may be modified to add a packet to the grant for transmission on a different set of time-frequency resources or a different set of multiple-input multiple-output (MIMO) layers, modify a time-frequency resource allocation of the grant, modify the waveform utilized for the grant, modify the transmit-diversity scheme utilized for the grant, or indicate specific processing for the packet.

Abstract: A base station may maintain multiple beam pair links, with one being actively used for communication. The active beam pair may become blocked. Accordingly, it may be necessary to switch to another beam pair. The apparatus may be an apparatus for wireless communication. The apparatus for wireless communication may include a memory and at least one processor coupled to the memory. The at least one processor is configured to determine a set of active beam pairs including at least a first beam pair and a second beam pair and select the first beam pair. The at least one processor is also configured to predict that the first beam pair is blocked, the prediction based on an expiration of a timer and sweep through the set of active beam pairs based on predicting that the first beam pair is blocked.

Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to control resource sets (coresets) for transmitting physical downlink control channels using either a single-carrier waveform or a multicarrier waveform in communications systems operating according to new radio (NR) technologies. In an exemplary method, a base station may determine whether a control resource set (coreset), of time and frequency resources within a control region of system bandwidth and configured for a user equipment (UE), conveys a physical downlink control channel (PDCCH) via a single-carrier waveform or a multicarrier waveform, and transmit the PDCCH to the UE using the determined waveform.

Abstract: A method and apparatus for enhancing channel estimation by using a binary tree based PDCCH search space in a new radio wireless communication system is disclosed. For example, a UE may identify an aggregation level profile having an aggregation level value for one or more aggregation levels, wherein each aggregation level corresponds to a respective number of resources to use for decoding a PDCCH, determine one or more decoding candidates for the UE from among a plurality of available decoding candidates defined as nodes in a binary tree for a search space based on the aggregation level profile, determine respective CCEs corresponding to each of the one or more decoding candidates, each respective CCE including one or more REGs, and performing channel estimation for each of the respective CCEs for use in demodulating and decoding downlink control information for the UE in the PDCCH.
