Abstract: Methods, systems, and apparatuses are described for wireless communication at a base station. The base station may transmit a control message to a set of user equipments (UEs) using a directional transmission having a first beamform width. The base station may exchange, according to the control message, data messages with a first UE of the set of UEs using a directional transmission having a second beamform width. The second beamform width may be different from the first beamform width. The base station may exchange, according to the control message, data messages with a second UE of the set of UEs using a directional transmission having a third beamform width. The third beamform width may be different from the first beamform width, the second beamform width, or both.

Abstract: Methods, systems, and devices for wireless communications are described that provide for signaling and switching of beam pair links (BPLs) for directional transmission beams between a base station and a user equipment (UE). A threshold value may be determined, which corresponds to an amount of time for a UE to receive and decode control information, and apply a different BPL than a current BPL that that is in use. The UE may maintain a BPL for data, which is used during data transmission time intervals (TTIs) until an indication is received to change the BPL for data. The UE and the base station may determine to change between BPLs based at least in part on the threshold value and a scheduling offset between a control channel transmission that allocates resources for a data TTI and a start of the data TTI.

Abstract: Methods, systems, devices, and apparatuses are described for phase noise estimation. A transmitting device identifies a phase noise metric associated with a receiving device. The phase noise metric provides an indication of the expected phase noise for the receiving device. The transmitting device selects a plurality of pilot tones adjacent to each other and a plurality of null tones for a transmission to the receiving device based on the phase noise metric. The plurality of null tones may be adjacent to and on both sides of the pilot tones in the frequency domain. The transmitting device identifies its own phase noise metric and select the pilot tones adjacent to each other and plurality of null tones in further consideration of its own phase noise metric. The receiving device may use the pilot tones and plurality of adjacent null tones to determine a phase noise estimation for the transmission.

Abstract: At a receiver, errors may occur in estimating phase trajectory based on PT-RS due to a window effect. In order to address the problem of such errors, a transmitter determines at least one location for inserting PT-RS samples into a sequence of a plurality of samples, wherein a first set of the samples comprises a first number of samples at a beginning of the sequence and/or a second number of samples at an end of the sequence, and wherein the at least one location for the PT-RS samples is within a second set of the plurality of samples. The apparatus inserts the PT-RS samples into the sequence based on the determined at least one location and transmits a signal based on the inserted PT-RS samples. A receiver extracts the PT-RS samples and estimates phase errors for data samples in the received transmission based on the extracted PT-RS samples.

Abstract: In aspects, an initial access procedure may include a random access channel (RACH) procedure. Thereby, a user equipment (UE) may transmit, to a base station, a random access channel preamble over a first bandwidth of a system bandwidth that is less than the system bandwidth, receive, from the base station after transmitting the random access channel preamble, a random access channel response over the first bandwidth, receive, from the base station after transmitting the random access channel preamble, one or more reference signals over one or more portions of a second bandwidth of the system bandwidth, the second bandwidth being wider than the first bandwidth, the one or more portions of the second bandwidth being different than the first bandwidth, the one or more reference signals being usable for determining a beam to be used for data communication over the second bandwidth, and receive, from the base station, a physical downlink shared channel (PDSCH) over the second bandwidth via the beam based on the one or more reference signals.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may report a phase-noise compensation reference signal (PCRS) configuration to a base station to enable per-UE PCRS signaling. For example, a UE may operate in a wireless communications system using carrier frequencies greater than 6 GHz, which may be affected by phase noise. The UE may accordingly determine a PCRS configuration based on a capability to receive signals. The PCRS configuration may include a resource mapping for one or more PCRS, a number of PCRS ports used for PCRS, a multiplexing scheme for one or more PCRS ports, or the UE's phase noise estimation capability. The UE may then transmit a reporting message including the PCRS configuration to a base station. The base station may use the PCRS configuration for PCRS transmissions to the UE.

Abstract: There is a need for a beam tracking technique that reduces the time needed to perform a beamforming procedure and that reduces beam overhead. The apparatus may determine a mapping between a first beam associated with a first type of channel and a second beam associated with a second type of channel. In an aspect, the first type of channel may be different than the second type of channel. The apparatus may receive the first beam associated with the first type of channel and the second beam associated with the second type of channel. In an aspect, the first beam and the second beam may be received from a second device.
