Abstract: A UE may identify a first indication associated with a first signaling to be received in a time interval and identify a second indication associated with a second signaling to be received in the time interval. The UE may select to receive and receive, in the time interval, at least one of the first signaling or the second signaling based on at least one of the first or second indications. One or more of the first and second indications may be received from a BS or determined by the UE via predefined or other means. A BS may convey indications of the first and/or second signaling. The first and second indications may be transmitted sufficiently before the signaling in an effort to allow the UE to select and tune its receiver beam in the direction of the signaling to be received.

Abstract: An apparatus for wireless communication selects a recommendation for the need. The apparatus selects the resource to transmit a phase tracking reference signal based on a condition of a communication system. The apparatus performs at least one of transmitting an indication of the selected recommendation for the resource to a second wireless communication device or transmitting at least one of information or a reference signal to the second device to assist the second device in determining the resource. In an aspect, the selection may be made based on receiving a request for a recommendation from the second wireless communication device or the transmitting the at least one of the information or the reference signal are based on a request received.

Abstract: Aspects of the present disclosure provide for random access channel (RACH) configuration in wireless communication systems. In some examples, a RACH configuration may be selected for use by a scheduled entity in transmitting a RACH signal to a scheduling entity based on an estimated timing advance value. The RACH configuration may include, for example, a transmission time of the RACH signal and/or a RACH waveform configuration identifying at least a cyclic prefix (CP) length and a guard time (GT) for the RACH signal. In some examples, the CP and GT length may each be set to the difference between an estimated maximum round-trip time (RTT) and an estimated minimum RTT between the scheduled entity and the scheduling entity. In some examples, the timing advance value may be estimated as the estimated minimum RTT.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a plurality of reference signals, each reference signal of the plurality of reference signals corresponding to a beam of a plurality of beams. The UE may transmit a beam report comprising measurement information associated with the plurality of reference signals, wherein the measurement information is based on an output of a linear principal component analysis (PCA) filter. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a source distributed unit (DU) may receive, from a user equipment (UE), a measurement report indicating at least one transmission configuration indicator state (TCI) state associated with a target DU. The source DU may transmit, to the target DU, an indication of a set of candidate TCI states from the at least one TCI state for a dynamic cell switch of the UE from a source cell of the source DU to a target cell of the target DU. As such, the UE may transmit, to the target DU, a random access message or an uplink message in accordance with a first TCI state from the set of candidate TCI states.

Abstract: In operation, the UE in the cell (SpCell/SCell) may be configured to operate with beam group specific BFRs, cell-level BFRs, or combinations of them under a beam failure configuration that is determined according to various rules. A method of wireless communication performed by a user equipment (UE) and a UE is disclosed. The method includes determining a beam failure configuration for a serving cell, the beam failure configuration including at least one of a beam failure parameter of a beam group or a beam failure parameter of a cell; and detecting, in the serving cell based at least in part on the beam failure configuration, a beam failure recovery (BFR) based at least in part on the beam failure configuration. The beam failure configuration is determined based on various rules that control the operation of the BFR.
