Abstract: Techniques for implicitly configuring resources for radio link monitoring or beam failure detection. An example method generally includes identifying that RLM resources or BFD resources are configured implicitly by at least in part: obtaining TCI states, for PDDCH CORESETs, obtaining an indication that at least one of the TCI states is activated to become an active TCI state of the PDCCH CORESETs, identifying one or more CSI-RS resources configured in the at least one of active TCI states of the PDCCH CORESETs, and if the UE does not support RLM or BFD based on the CSI-RS or the one or more CSI-RS resources are AP or SP, determining a SS block for RLM or BFD that has a QCL relationship with the one or more CSI-RS resources of the at least one of active TCI states; and performing RLM or BFD based on the SS block.

Abstract: The present disclosure involves determining base station (BS) beams for communicating between a UE and the BS. The BS may use sensor data or beam management reporting history to assist with determining one or more appropriate beams. The sensor data may include camera images, radar data, or lidar data, and be used to model the cell environment served by the BS. The BS may obtain reporting data from multiple UEs over time indicating the quality of beams received by the UEs at various locations in the cell environment and model the cell environment based on the reporting data. The BS may associate beams with possible UE locations within the cell environment and use the associations to determine beams for communicating with a UE after determining the UE's location.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for a DPD training procedure. A base station may transmit, for a plurality of iterations, a signal to at least one UE through a plurality of transmit chains and with application of DPD. The signal transmitted for each iteration may be transmitted with a BW that extends over a plurality of subcarriers and includes pilots extending over a BW subset that increases in subcarrier size for each iteration. The base station may receive, for each iteration, feedback from the at least one UE based on the transmitted signal and apply DPD to each of the plurality of transmit chains based on the feedback. Accordingly, the base station may transmit to one or more UEs through the plurality of transmit chains and with application of the DPD pilot signals that extend over the entire BW.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine the subcarrier spacing and carrier frequency used by a user equipment (UE) for communicating with the base station. The base station may select a sounding reference signal (SRS) configuration for the UE that is based on the subcarrier spacing and carrier frequency used by the UE. The SRS configuration may define the temporal spacing between repetitions of the SRS. The base station may indicate the SRS configuration to the UE so that the UE transmits repetitions of the SRS according to the SRS configuration. The base station may measure the SRS repetitions from the UE to determine the Doppler frequency for the uplink channel. The base station may use the uplink Doppler frequency to select a demodulation reference signal (DMRS) configuration for the UE.

Abstract: Methods related to wireless communication systems and the transmission of code blocks on such systems are provided. A wireless communication device interleaves a plurality of code block segments in time and frequency. The segments are interleaved by mapping a first code block segment of the plurality of code block segments to a first resource located at a first time and a first frequency, wherein the first code block segment is associated with a first code block, and mapping a second code block segment of the plurality of code block segments to a second resource based on at least one of the first time or the first frequency of the first resource and a code block proximity parameter, wherein the second code block segment is associated with a second code block different from the first code block. The device then transmits the plurality of interleaved code block segments. Other features are also claimed and described.

Abstract: Wireless communication devices are adapted to facilitate path loss estimations utilizing a synchronization signal block (SSB). According to one example, a wireless communication device can obtain a spatial relation reference signal. The wireless communication device may determine a SSB in quasi-colocation (QCL) with the received spatial relation reference signal. A path loss may be measured utilizing the determined SSB. The wireless communication device may conduct transmit power control based on the measured path loss associated with the determined SSB. Other aspects, embodiments, and features are also included.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, within a subframe, a plurality of sidelink control channel signals providing scheduling information for a plurality of sidelink shared channel signals that are also received within the subframe. The UE may determine to use one or more of the plurality of sidelink control channel signals as pilot signals for decoding the plurality of sidelink shared channel signals. The UE may decode the plurality of sidelink shared channel signals based at least in part on the plurality of sidelink control channel signals as pilot signals.

Abstract: Methods, systems, and devices for wireless communications are described. In some cases, a user equipment (UE) may be configured to use certain reference signals to perform radio link monitoring and/or beam failure detection of a communication link. In some cases, the UE may identify a first reference signal configured for the UE and a second reference signal configured for radio link monitoring and/or beam failure detection. In some cases, the UE may determine a synchronization signal block (SSB) for the radio link monitoring or the beam failure detection of the control channel based on an association between the second reference signal and the SSB. For example, the UE may be configured to follow a sequence including hops between different reference signals to arrive at the SSB. The UE may then perform the radio link monitoring and/or the beam failure detection using the SSB.

Abstract: Techniques for synchronized reception beam refinement are described herein. A base station may indicate to a user equipment (UE) a time when a reception beam refinement event may occur. The UE may initiate a synchronized reception beam refinement procedure based on receiving the indication from the base station. The UE may identify a new reception beam configuration based on data stored locally by the UE and ongoing background calculations that the UE carries out based on periodic beam reference signals. At the time indicated, the UE may adjust the reception beam configuration of a reception beam. The base station may initiate one or more link maintenance procedures based on a reception beam refinement event occurring. Such techniques may reduce the loss of data due to link degradation related to channel state feedback inconsistency (CSF) after a reception beam refinement event.
